The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect their
conversion into Class A shares eight years after purchase. The since inception
returns for Class C shares reflect their conversion into Class A shares ten
years after purchase. Class I shares are available for purchase exclusively by
investors through (i) tax-exempt retirement plans with assets of at least $1
million (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans,

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases -- the longest stretch of increases in 25 years. At
its September meeting, the Fed again kept its target rate unchanged, and
indicated that any future rate increases would be driven by the weight of
economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
funds. Because prevailing interest rates were still at relatively low levels,
investors increasingly sought out lower-quality, higher yielding bonds. The
increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

                                                                               3


PERFORMANCE ANALYSIS

The fund returned 4.49 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.45 percent for the period.

The performance for the four share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

A variety of factors contributed positively to the fund's performance during the
reporting year. Reflecting our view that Treasury rates would continue to rise,
we kept the portfolio's duration (a measure of interest-rate sensitivity) lower
than that of its benchmark for the first eight months of the period. This
conservative positioning benefited the fund as interest rates continued to climb
as anticipated. In June, when economic data started to weaken and it appeared
that rates were done climbing, we increased the duration of the portfolio to be
more in line with the Lehman Brothers Municipal Bond Index. This less-defensive
positioning also contributed positively to fund returns as the yield curve began
to flatten in the latter months of the period.

The fund's positioning along the yield curve remained consistent throughout the
period. We favored the longer-term segment of the curve, purchasing bonds
primarily in the 25-to-30 year maturity range. This proved advantageous as
longer-dated issues outperformed those with shorter maturities. We also
purchased premium coupon bonds priced to 10 years or shorter, and added to the
fund's holdings in inverse floating-rate securities,* both of which added income
to the fund. We continued to avoid zero coupon bonds, which have been volatile,
as well as non-callable bonds. The fund also benefited considerably from new
issues being brought into the marketplace that refunded current holdings in the
portfolio, which allowed the fund to capture appreciation gains.

For hedging purposes, we used Bond Market Association (BMA) swaps and to a
lesser extent, Treasury futures. BMA swaps are more closely tied to the

security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

municipal market than are Treasury futures, which we believe makes them a more
effective hedging tool.

The fund maintained an emphasis on the essential services sectors of the market,
such as water and sewer and education bonds. We selectively added some health
care issues to the portfolio but continued to avoid housing bonds. These factors
were also additive to performance whereas an underweight relative to the Lehman
Brothers Municipal Bond Index in the tax-supported debt and education sectors
tempered returns somewhat. We continued to keep the fund's Alternative Minimum
Tax (AMT) exposure low, at approximately two percent of total assets.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

       June 30 without charge by visiting our Web site at www.vankampen.com.
       This information is also available on the Securities and Exchange
       Commission's Web site at http://www.sec.gov.

                                                                               9


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 4/1/06 - 9/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
cost would have been higher.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                              11


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund and changes made
in the Fund's portfolio management team over time. The Fund discloses
information about its portfolio management team members and their experience in
its prospectus. The trustees also discuss certain other services which are
provided on a cost-reimbursement basis by the investment adviser or its
affiliates to the Van Kampen funds including certain accounting, administrative
and legal services. The Board has determined that the nature, extent and quality
of the services provided by the investment adviser support its decision to
approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

 12


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              13

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Insured Tax Free Income Fund (the "Fund") is organized as a series of
the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as
a diversified open-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment
objective is to provide investors a high level of current income exempt from
federal income taxes, with liquidity and safety of principal, primarily through
investment in a diversified portfolio of insured municipal securities. The Fund
commenced investment operations on December 14, 1984. The Fund offers Class A
Shares, Class B Shares, Class C Shares and Class I Shares. Each class of shares
differs by its initial sales load, contingent deferred sales charges, the
allocation of class-specific expenses and voting rights on matters affecting a
single class.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Interest rate swaps are valued using market
quotations from brokers. Short-term securities with remaining maturities of 60
days or less are valued at amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At September 30, 2006, the Fund had $49,356,004 when-issued and
delayed delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

and to distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    At September 30, 2006, the cost and related gross unrealized appreciation
and depreciation were as follows:

<Table>

Gross tax unrealized depreciation...........................           (42,823)
                                                                --------------
Net tax unrealized appreciation on investments..............    $   58,467,830
                                                                ==============
</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 was as follows:

<Table>
<Caption>
                                                                 2006           2005
                                                                       
Distributions paid from:
  Ordinary income...........................................  $ 5,594,196    $ 1,834,335
  Tax-exempt income.........................................   43,813,499     46,489,249
  Long-term capital gain....................................   18,477,514      9,269,523
                                                              -----------    -----------
                                                              $67,885,209    $57,593,107
                                                              ===========    ===========
</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities. A permanent difference relating to book to tax
accretion differences totaling $114,771 was reclassified from accumulated
undistributed net investment income to accumulated net realized gain.
Additionally, a permanent difference relating to the Fund's investments in other
regulated investment companies totaling $9,951 was reclassified from accumulated
undistributed net investment income to accumulated net realized gain. A
permanent book to tax difference of $6,200 was reclassed from accumulated net
investment income to capital.

    As of September 30, 2006, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                             
Undistributed ordinary income...............................    $  362,927
Undistributed tax-exempt income.............................     1,719,881
Undistributed long-term capital gain........................     3,333,429
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of gains or losses recognized for tax purposes on
open futures transactions on September 30, 2006.

                                                                              39

F. INSURANCE EXPENSES The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured
secondarily through the Fund's portfolio insurance policy. Insurance premiums
are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.

G. EXPENSE REDUCTIONS During the year ended September 30, 2006, the Fund's
custody fee was reduced by $57,640 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                        % PER ANNUM

Next $500 million...........................................       .475%
Over $1.5 billion...........................................       .450%
</Table>

    For the year ended September 30, 2006, the Fund recognized expenses of
approximately $21,900 representing legal expenses provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the year ended September 30,
2006, the Fund recognized expenses of approximately $124,900 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
September 30, 2006, the Fund recognized expenses of approximately $549,300
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and

common shares of those funds selected by the trustees. Investments in such funds
of $257,791 are included in "Other" assets on the Statement of Assets and
Liabilities at September 30, 2006. Appreciation/depreciation and distributions
received from these investments are recorded with an offsetting
increase/decrease in the deferred compensation obligations and do not affect the
net asset value of the Fund. Benefits under the retirement plan are payable upon
retirement for a ten-year period and are based upon each trustee's years of
service to the Fund. The maximum annual benefit per trustee under the plan is
$2,500.

    For the year ended September 30, 2006, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of

4. REDEMPTION FEES

The Fund assesses a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund. For the year ended September 30,
2006, the Fund received redemption fees of approximately $800, which are
reported as part of "Cost of Shares Repurchased" on the Statement of Changes in
Net Assets. The per share impact from redemption fees paid to the Fund was less
than $0.01.

                                                                              41

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $536,339,837 and $574,524,736,
respectively.

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's holdings, including derivative instruments, are marked to
market each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying a futures contract. Summarized
below are the specific types of derivative financial instruments used by the
Fund.

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Bonds or Notes for duration and risk management purposes and typically closes
the contract prior to the delivery date. Upon entering into futures contracts,
the Fund maintains an amount of cash or liquid securities with a value equal to
a percentage of the contract amount with either a futures commission merchant
pursuant to rules and regulations promulgated under the 1940 Act, as amended, or
with its custodian in an account in the broker's name. This amount is known as
initial margin. During the period the futures contract is open, payments are
received from or made to the broker based upon changes in the value of the
contract (the variation margin). The risk of loss associated with a futures
contract is in excess of the variation margin reflected on the Statement of
Assets and Liabilities.

    Transactions in futures contracts, for the year ended September 30, 2006,
were as follows:

Futures Opened..............................................      10,944
Futures Closed..............................................     (13,046)
                                                                 -------
Outstanding at September 30, 2006...........................         890
                                                                 =======
</Table>

B. INVERSE FLOATING RATE SECURITIES An Inverse Floating Rate security is one
where the coupon is inversely indexed to a short-term floating interest rate
multiplied by a specified factor. As the floating rate rises, the coupon is
reduced. Conversely as the floating rate declines, the coupon is increased. The
price of these securities may be more volatile than the price of a comparable
fixed rate security. These instruments are typically used by the Fund to enhance
the yield of the portfolio. These instruments are identified in the Portfolio of
Investments.

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Fund's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Fund's agreement with a
counterparty to pay, in the future, a fixed or variable rate payment in exchange
for the counterparty paying the Fund a variable or fixed rate payment, the
accruals for which would begin at a specified date in the future (the "effective
date"). The amount of the payment obligation is based on the notional amount of
the forward swap contract and the termination date of the swap (which is akin to
a bond's maturity). The value of the Fund's swap commitment would increase or
decrease based primarily on the extent to which long-term interest rates for
bonds having a maturity of the swap's termination date increases or decreases.
The Fund may terminate a swap contract prior to the effective date, at which
point a realized gain or loss is recognized. When a forward swap is terminated,
it ordinarily does not involve the delivery of securities or other underlying
assets or principal, but rather is settled in cash on a net basis. The Fund
intends, but is not obligated, to terminate its forward swaps before the
effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Fund upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of the Fund with a value approximately equal to the amount of any
unrealized gain. Reciprocally, when the Fund has an unrealized loss on a swap
contract, the Fund has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash, if any, for segregating
purposes is shown on the Statement of Assets and Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $1,072,700 and $58,600
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

                                                                              43

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint
also alleges that the Van Kampen funds paid excessive commissions to Morgan
Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The impact to the
Fund's financial statements, if any, is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

VAN KAMPEN INSURED TAX FREE INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen Insured Tax Free Income
Fund:

    We have audited the accompanying statement of assets and liabilities of Van
Kampen Insured Tax Free Income Fund (the "Fund"), including the portfolio of
investments, as of September 30, 2006, and the related statement of operations
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen Insured Tax Free Income Fund at September 30, 2006, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for each
of the five years in the period then ended in conformity with U.S. generally
accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed, however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases -- the longest stretch of increases in 25 years. At
its September meeting, the Fed again kept its target rate unchanged, and
indicated that any future rate increases would be driven by the weight of
economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in the latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
mutual funds. Because prevailing interest rates were still at relatively low
levels, investors increasingly sought out lower-quality, higher yielding bonds.
The increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

PERFORMANCE ANALYSIS

The fund returned 8.41 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.45 percent for the period.

The performance for the three share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

A variety of factors contributed to the fund's strong performance during the
reporting year. The fund's allocation to high yield bonds and lower rated bonds
was a considerable driver of performance. Given the relatively low level of
interest rates, investors seeking yield turned to the high yield bond market,
which led to further tightening of credit spreads. (Credit spreads measure the
added compensation investors require to assume risk. When credit spreads
tighten, bonds with lower credit ratings generally outperform higher quality
bonds.) At the same time, supply of new high yield bonds continued to decline.
The combination of steep demand, narrowing spreads, and decreasing supply served
as catalysts to the high yield market. The fund's high yield holdings realized
price appreciation, especially in the health care, special tax district and
master settlement tobacco bonds.

The fund made a major sector change which allowed the fund to capture
considerable gains during the period. August, we sold the portfolio's holdings
in special facility airline revenue bonds, which represented over 10 percent of
the fund's holdings. The airline industry has made a significant turnaround
since September 11, 2001. Consequently, these bonds rallied sharply from their
very depressed levels of only a few years ago. We believed that the prices bonds
were trading at in the summer did not adequately reflect the geopolitical and
oil price risks inherent in the industry. We therefore decided this was a good
time for the fund to exit the sector and lock in gains.

The funds from sale of airline issues were primarily redeployed to increasing
the portfolio's exposure to inverse floating-rate securities,* which offered
attractive yields. At the same time, we initiated hedging strategies to help
offset the additional price volatility of these derivatives. Inverse floaters
held by the fund

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.
                                                                               3


carry a AAA rating and, as such, the fund's allocation to higher-rated bonds
increased while the non-rated portion of the portfolio declined to approximately
60 percent of holdings as of the end of the period.

While the fund outperformed its benchmark for the reporting period, the Lehman
Brothers Municipal Bond Index, a few isolated issues declined due to
security-specific reasons. Holdings in the higher education and affordable
senior housing sectors also tempered performance early in the period.

The fund remained well diversified across the municipal bond market. As of
September 30, 2006, the life care, acute care, and special tax/assessment
district sectors represented the largest sector weightings.

We closely manage the growth of the fund's asset base as an important part of
our commitment to the fund's existing shareholders. Based on our analysis of the
supply and demand trends in the market, we believed the prudent course was to
keep the fund closed to new investors during the period.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 4/1/06 - 9/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
cost would have been higher.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors
 10


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund and changes made
in the Fund's portfolio management team over time. The Fund discloses
information about its portfolio management team members and their experience in
its prospectus. The trustees also discuss certain other services which are
provided on a cost-reimbursement basis by the investment adviser or its
affiliates to the Van Kampen funds including certain accounting, administrative
and legal services. The Board has determined that the nature, extent and quality
of the services provided by the investment adviser support its decision to
approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

                                                                              11


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Strategic Municipal Income Fund (the "Fund") is organized as a series
of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered
as a diversified, open-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment
objective is to seek to provide investors a high level of current income exempt
from federal income tax primarily through investment in a diversified portfolio
of medium- and lower-grade municipal securities. The Fund commenced investment
operations on June 28, 1985. The Fund offers Class A Shares, Class B Shares,
Class C Shares and Class I Shares. Each class of shares differs by its initial
sales load, contingent deferred sales charges, the allocation of class-specific
expenses and voting rights on matters affecting a single class. As of September
30, 2006, there have been no sales of Class I Shares.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. The Fund
may purchase and sell securities on a "when-issued" or "delayed delivery" basis,
with settlement to occur at a later date. The value of the security so purchased
is subject to market fluctuations during this period. The Fund will segregate
assets with the custodian having an aggregate value at least equal to the amount
of the when-issued or delayed delivery purchase commitments until payment is
made. At September 30, 2006 the Fund had $15,343,221 of when-issued or delayed
delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

                                                                              53

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At September 30, 2006 the Fund had an accumulated capital loss
carryforward for tax purposes of $115,213,774 which will expire according to the
following schedule.

</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 were as follows:

<Table>
<Caption>
                                                                 2006           2005
                                                                       
Distributions paid from:
  Ordinary income...........................................  $    57,989    $     1,843
  Tax-exempt income.........................................   84,689,847     67,834,052
                                                              -----------    -----------
                                                              $84,747,836    $67,835,895
                                                              ===========    ===========
</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gain/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

and appropriately reclassified on the Statement of Assets and Liabilities.
Permanent book and tax differences relating to a portion of the capital loss
carryforward expiring in the current year totaling $1,076,939 has been
reclassified from accumulated net realized loss to capital. Additionally,
permanent book and tax differences relating to the Fund's investment in other
regulated investment companies totaling $6,390 were reclassified from
accumulated undistributed net investment income to accumulated net realized
loss. Additionally, permanent book to tax accretion differences totaling
$124,534 were reclassified from accumulated undistributed net investment income
to accumulated net realized loss. A permanent book to tax difference relating to
the sale of PIK bonds totaling $5,156,978 was reclassified from accumulated
undistributed net investment income to accumulated net realized loss.

    As of September 30, 2006 the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                             
Undistributed Ordinary income...............................    $  192,687
Undistributed Tax-exempt income.............................     5,043,163
</Table>

    Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of the deferral of losses relating to wash sale
transactions, the capitalization of reorganization and restructuring costs,
gains or losses recognized for tax purposes on open futures transactions at
September 30, 2006 and post October losses of $6,025,399 which are not
recognized for tax purposes until the first day of the following fiscal year.

F. EXPENSE REDUCTIONS During the year ended September 30, 2006 the Fund's
custody fee was reduced by $46,097 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management ("the Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance

of "Legal" expenses on the Statement of Operations. Services provided pursuant
to the Accounting Services and CCO Employment agreement are reported as part of
"Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
September 30, 2006 the Fund recognized expenses of approximately $672,700
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $163,813 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2006.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund. Benefits under the
retirement plan are payable upon retirement for a ten-year period and are based
upon each trustee's years of service to the Fund. The maximum annual benefit per
trustee under the plan is $2,500.

    For the year ended September 30, 2006 Van Kampen, as distributor for the
Fund, received commissions on sales of the Fund's Class A shares of
approximately $362,400 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $263,500 Sales charges do not represent expenses of the
Fund.

4. REDEMPTION FEE

The Fund assesses a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within 30 days of purchase. The redemption
fee is paid directly to the Fund. For the year ended September 30, 2006 the Fund
received redemption fees of approximately $12,300 which are reported as part of
"Cost of Shares Repurchased" on the Statement of Changes in Net Assets. The per
share impact from redemption fees paid to the fund was less than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $1,585,168,666 and $1,602,420,266,
respectively.

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio, to manage the portfolio's effective yield, maturity and duration, or
generate potential gain. All of the Fund's portfolio holdings, including
derivative instruments, are marked to market each day with the change in value
reflected in unrealized appreciation/depreciation. Upon disposition, a realized
gain or loss is recognized accordingly, except when taking delivery of a
security underlying a

                                                                              57

futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract. Risks may
arise as a result of the potential inability of the counter parties to meet the
terms of their contracts.

    Summarized below are the specific types of derivative financial instruments
used by the Fund.

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Securities and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the Fund's effective maturity and
duration. Upon entering into futures contracts, the Fund maintains an amount of
cash or liquid securities with a value equal to a percentage of the contract
amount with either a futures commission merchant pursuant to rules and
regulations promulgated under the 1940 Act, as amended, or with its custodian in
an account in the broker's name. This amount is known as initial margin. During
the period the futures contract is open, payments are received from or made to
the broker based upon changes in the value of the contract (the variation
margin).

    Transactions in future contracts for year ended September 30, 2006 are as
follows:

Outstanding at September 30, 2006...........................      2,670
                                                                 ======
</Table>

B. INVERSE FLOATING RATE SECURITIES An inverse floating rate security is one
where the coupon is inversely indexed to a short-term floating interest rate
multiplied by a specific factor. As the floating rate rises, the coupon is
reduced. Conversely, as the floating rate declines, the coupon is increased. The
price of these securities may be more volatile than the price of a comparable
fixed rate security. These instruments are typically used by the Fund to enhance
the yield of the portfolio. These instruments are identified in the Portfolio of
Investments.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $2,627,100 and $115,200
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint
also alleges that the Van Kampen funds paid excessive commissions to Morgan
Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

9. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes--an interpretation
of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes
by prescribing the minimum recognition threshold a tax position must meet before
being recognized in the financial statements. FIN 48 is effective for fiscal
years beginning after December 15, 2006. The impact to the Fund's Financial
Statements, if any is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

                                                                              59


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen Strategic Municipal
Income Fund:

    We have audited the accompanying statement of assets and liabilities of Van
Kampen Strategic Municipal Income Fund (the "Fund"), including the portfolio of
investments, as of September 30, 2006, and the related statement of operations
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen Strategic Municipal Income Fund at September 30, 2006, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for each
of the five years in the period then ended in conformity with U.S. generally
accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,
NY 10019-6064.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the fiscal period ended September 30, 2006, the total
operating expense ratio for Class B shares was lower and, as a result, the
performance of Class B shares was higher than that of Class A shares. There can
be no assurance that this will continue to occur in the future as the maximum
fees payable by Class B shares under the 12b-1 Plan are higher than those
payable by Class A shares.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in years one and two and
declining to zero after year five), a contingent deferred sales charge of 1.00
percent for Class C shares in year one and combined Rule 12b-1 fees and service
fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B
and C shares. The since inception and 10-year returns for Class B shares reflect
the conversion of Class B shares into Class A shares eight years after purchase.
The since inception returns for Class C shares reflect the conversion of Class C
shares into Class A shares ten years after purchase. Class I shares are
available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least
                                                                               1


$1 million (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans,
profit sharing and money purchase plans, defined benefit plans and non-qualified
deferred compensation plans), (ii) fee-based investment programs with assets of
at least $1 million and (iii) institutional clients with assets of at least $1
million. Class I shares are offered without any sales charges on purchases or
sales and do not include combined Rule 12b-1 fees and service fees. Figures
shown above assume reinvestment of all dividends and capital gains. SEC yield is
a calculation for determining the amount of portfolio income, excluding

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The Lehman Brothers California Insured

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases -- the longest stretch of increases in 25 years. At
its September meeting, the Fed again kept its target rate unchanged, and
indicated that any future rate increases would be driven by the weight of
economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
funds. Because prevailing interest rates were still at relatively low levels,
investors increasingly sought out lower-quality, higher yielding bonds. The
increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

Consistent with the national trend, the amount of municipal issues (both insured
and uninsured) that came to market in California declined for the overall
period. The large number of refundings that took place in the state in the
previous two years contributed to the reduction in supply. In addition, the low
level of interest rates more recently has led investors to seek securities with

                                                                               3


high yields, which resulted in a decline in demand for higher-quality, lower
yielding paper.

Despite the 20 percent drop in new issue supply, the State of California
remained the nation's largest issuer of municipal debt. The state's municipal
market continued to benefit from the strengthening of its credit fundamentals as
its credit rating was raised to A+ in 2006.

PERFORMANCE ANALYSIS

The fund returned 4.14 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmarks,
the Lehman Brothers California Insured Municipal Bond Index and the Lehman
Brothers Municipal Bond Index, returned 4.78 percent and 4.45 percent for the
period, respectively.

The performance for the four share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definitions.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the fiscal period ended September 30, 2006, the total
operating expense ratio for Class B shares was lower and, as a result, the
performance of Class B shares was higher than that of Class A shares. There can
be no assurance that this will continue to occur in the future as the maximum
fees payable by Class B shares under the 12b-1 Plan are higher than those
payable by Class A shares.

A variety of factors contributed positively to the fund's performance during the
reporting year. Reflecting our view that Treasury rates would continue to rise,
we kept the portfolio's duration (a measure of interest-rate sensitivity) lower
than that of the Lehman Brothers California Insured Municipal Bond Index for the
first eight months of the period. This conservative positioning benefited the
fund as interest rates continued to climb as anticipated. In June, when economic
data started to weaken and it appeared that rates were done climbing, we
increased the duration of the portfolio to be more in line with the Lehman
Brothers California Insured Municipal Bond Index. This less-defensive
positioning also contributed positively to fund returns as the yield curve began
to flatten in the latter months of the period.

The fund's positioning along the yield curve remained consistent throughout the
period. We favored the longer-term segment of the curve, purchasing bonds

 4


primarily in the 25-to-30 year maturity range. This proved advantageous as
longer-dated issues outperformed those with shorter maturities. We also
purchased premium coupon bonds priced to 10 years or shorter, and added to the
fund's holdings in inverse floating-rate securities,* both of which added income
to the fund. We continued to avoid zero-coupon bonds, which have been volatile,
as well as non-callable bonds. The fund also benefited considerably from new
issues being brought into the marketplace that refunded current holdings in the
portfolio, which allowed the fund to capture appreciation gains.

For hedging purposes, we used Bond Market Association (BMA) swaps and to a
lesser extent, Treasury futures. BMA swaps are more closely tied to the
municipal market than are Treasury futures, which we believe makes them a more
effective hedging tool.

The fund maintained an emphasis on the essential services sectors of the market,
such as water and sewer and education bonds. We selectively added some health
care issues to the portfolio but continued to avoid housing bonds. These factors
were also additive to performance whereas an underweight relative to the Lehman
Brothers California Insured Municipal Bond Index in the tax-supported debt and
education sectors tempered returns somewhat. In addition, the portfolio did not
contain any holdings subject to the Alternative Minimum Tax (AMT).

(*)An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and C Shares;
and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 4/1/06 - 9/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                               9


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund. The Fund
discloses information about its portfolio management team members and their
experience in its prospectus. The trustees also discuss certain other services
which are provided on a cost-reimbursement basis by the investment adviser or
its affiliates to the Van Kampen funds including certain accounting,
administrative and legal services. The Board has determined that the nature,
extent and quality of the services provided by the investment adviser support
its decision to approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees discuss with the investment adviser its revenues and expenses,
including among

 10


other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              11

VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen California Insured Tax Free Fund (the "Fund") is organized as a
series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is
registered as a diversified, open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide only California investors with a high level
of current income exempt from federal and California income taxes, with
liquidity and safety of principal, primarily through investment in a diversified
portfolio of insured California municipal securities. The Fund commenced
investment operations on December 13, 1985. The Fund offers Class A Shares,
Class B Shares, Class C Shares and Class I Shares. Each class of shares differs
by its initial sales load, contingent deferred sales charges, the allocation of
class specific expenses and voting rights on matters affecting a single class.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Interest rate swaps are valued using market
quotations from brokers. Short-term securities with remaining maturities of 60
days or less are valued at amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At September 30, 2006, the Fund had no when-issued and delayed
delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

                                                                              25

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    At September 30, 2006, the cost and related gross unrealized appreciation
and depreciation are as follows:

<Table>

                                                                ============

Gross tax unrealized depreciation...........................             -0-
                                                                ------------
Net tax unrealized appreciation on investments..............    $ 12,713,665
                                                                ============
</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and a portion of futures gains, which are
included in ordinary income for tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 was as follows:

                                                                 2006           2005
                                                                       
Distributions paid from:
  Ordinary income...........................................  $    95,063    $       755
  Tax exempt income.........................................    9,038,938      8,952,295
  Long-term capital gain....................................    2,883,508      1,527,321
                                                              -----------    -----------
                                                              $12,017,509    $10,480,371
                                                              ===========    ===========
</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities. A permanent difference relating to the Fund's
investment in other regulated investment companies totaling $4,955 was
reclassified from accumulated undistributed net investment income to accumulated
net realized gain. Additionally, a permanent book and tax difference of $2
related to book to tax accretion differences was reclassified from accumulated
undistributed net investment income to accumulated net realized gain.

</Table>

    For the year ended September 30, 2006, the Fund recognized expenses of
approximately $10,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the year ended September 30,
2006, the Fund recognized expenses of approximately $62,300 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
September 30, 2006, the Fund recognized expenses of approximately $101,000
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $130,897 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2006.
Appreciation/depreciation and distributions received from these investments are
recorded with

                                                                              27

an offsetting increase/decrease in the deferred compensation obligation and do
not affect the net asset value of the Fund. Benefits under the retirement plan
are payable upon retirement for a ten-year period and are based upon each
trustee's years of service to the Fund. The maximum annual benefit per trustee
under the plan is $2,500.

    For the year ended September 30, 2006, Van Kampen as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $80,800 and contingent deferred sale charge (CDSC) on redeemed
shares of approximately $25,900. Sales charges do not represent expenses of the
Fund.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $69,282,470 and $74,941,574,
respectively.

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In these instances, the recognition of gain or loss is
postponed until the disposal of the security underlying the futures contract.

    Summarized below are the specific types of derivative financial instruments
used by the Fund.

A. FUTURES CONTRACTS During the period, the Fund invested in futures contracts,
a type of derivative. A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Notes and typically closes
the contract prior to the delivery date. The contracts are generally used to
manage the portfolio's effective maturity and duration. Upon entering into
futures contracts, the Fund maintains an amount of cash or liquid securities
with a value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin).

    Transactions in futures contracts for the year ended September 30, 2006,
were as follows:

<Table>

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2005...........................     -0-
Futures Opened..............................................     182
Futures Closed..............................................    (182)
                                                                ----
Outstanding at September 30, 2006...........................     -0-

</Table>

B. INVERSE FLOATING RATE SECURITIES An inverse floating rate security is one
where the coupon is inversely indexed to a short-term interest rate multiplied
by a specific factor. As the floating rate rises, the coupon is reduced.
Conversely, as the floating rate declines, the coupon is increased. The price of
these securities may be more volatile than the price of a comparable fixed rate
security. These instruments are typically used by the Fund to enhance the yield
of the portfolio. These instruments are identified in the Portfolio of
Investments.

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer,

                                                                              29


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

generally to more closely align the Fund's interest rate sensitivity with that
of the broader municipal market. Forward interest rate swap transactions involve
the Fund's agreement with a counterparty to pay, in the future, a fixed or
variable rate payment in exchange for the counterparty paying the Fund a
variable or fixed rate payment, the accruals for which would begin at a
specified date in the future (the "effective date"). The amount of the payment
obligation is based on the notional amount of the forward swap contract and the
termination date of the swap (which is akin to a bond's maturity). The value of
the Fund's swap commitment would increase or decrease based primarily on the
extent to which long-term interest rates for bonds having a maturity of the
swap's termination date increases or decreases. The Fund may terminate a swap
contract prior to the effective date, at which point a realized gain or loss is
recognized. When a forward swap is terminated, it ordinarily does not involve
the delivery of securities or other underlying assets or principal, but rather
is settled in cash on a net basis. The Fund intends, but is not obligated, to
terminate its forward swaps before the effective date. Accordingly, the risk of
loss with respect to the swap counterparty on such transactions is limited to
the credit risk associated with a counterparty failing to honor its commitment
to pay any realized gain to the Fund upon termination. To reduce such credit
risk, all counterparties are required to pledge collateral daily (based on the
daily valuation of each swap) on behalf of the Fund with a value approximately
equal to the amount of any unrealized gain. Reciprocally, when the Fund has an
unrealized loss on a swap contract, the Fund has instructed the custodian to
pledge cash or liquid securities as collateral with a value approximately equal
to the amount of the unrealized loss. Collateral pledges are monitored and
subsequently adjusted if and when the swap valuations fluctuate. Restricted
cash, if any, for segregating purposes is shown on the Statement of Assets and
Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $0 for Class B
and Class C Shares, respectively. These amounts may be recovered from future
payments under the distribution plan or CDSC. To the extent the unreimbursed
receivable has been fully recovered, the distribution fee is reduced.

8. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint
also alleges that the Van Kampen funds paid excessive commissions to

 30


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

Morgan Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

9. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes--an interpretation
of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes
by prescribing the minimum recognition threshold a tax position must meet before
being recognized in the financial statements. FIN 48 is effective for fiscal
years beginning after December 15, 2006. The impact to the Fund's financial
statements, if any, is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for the
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

                                                                              31

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen California Insured Tax
Free Fund:

    We have audited the accompanying statement of assets and liabilities of Van
Kampen California Insured Tax Free Fund (the "Fund"), including the portfolio of
investments, as of September 30, 2006, and the related statement of operations
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen California Insured Tax Free Fund at September 30, 2006, the results
of its operations for the year then ended, the changes in its net assets for
each of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended in conformity with U.S.
generally accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen--as well as several other decisions
by other judges in the Southern District of New York and certain other courts
that have dismissed similar complaints against other investment funds--plaintiff
in the derivative action has determined that the suit would be unsuccessful, if
pursued further. Accordingly, plaintiff has asked Judge Owen to dismiss the
action. No attorneys' fees will be paid by defendants and no consideration will
be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,
NY 10019-6064.

PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect the
conversion of Class B shares into Class A shares eight years after purchase. The
since inception returns for Class C shares reflect the conversion of Class C
shares into Class A shares ten years after purchase. Class I shares are
available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least $1 million (including 401(k) plans, 457
plans, employer-sponsored 403(b) plans, profit sharing and money purchase plans,
defined benefit plans and non-qualified deferred compensation plans), (ii)
fee-based investment programs with assets of at least $1 million and (iii)
institutional clients with assets of at least $1 million. Class I shares are
offered without any sales charges on purchases or sales and do not include
combined Rule 12b-1 fees and service fees. Figures shown above assume
reinvestment of all dividends and capital gains. SEC yield is a calculation

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases--the longest stretch of increases in 25 years. At its
September meeting, the Fed again kept its target rate unchanged, and indicated
that any future rate increases would be driven by the weight of economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
funds. Because prevailing interest rates were still at relatively low levels,
investors increasingly sought out lower-quality, higher yielding bonds. The
increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

                                                                               3


PERFORMANCE ANALYSIS

The fund returned 5.46 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.45 percent for the period.

The performance for the four share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

We sought opportunities to enhance the portfolio's yield, selectively adding
bonds to the portfolio that we believed were both attractively valued and
offered greater future total return prospects. To implement this strategy, we
lowered the fund's exposure to AAA rated bonds, investing the proceeds into
higher yielding BBB rated bonds. As a result, the fund was overweighted versus
the Lehman Brothers Municipal Bond Index in BBB and non-rated bonds, which
proved advantageous as this portion of the market outperformed higher-rated
bonds. Despite this shift in credit allocation, however, the fund's overall
credit quality remained high.

The fund also benefited from an overweight relative to the Lehman Brothers
Municipal Bond Index in zero coupon bonds, which outperformed current and
premium coupon bonds during the reporting year, as well as an overweight in the
hospital sector which improved due to credit spread tightening. Holdings in the
tobacco sector also did well as the litigation environment has become favorable
for tobacco companies, demand for the bonds remains strong, and the industry
continues to prosper. On a less positive note, an overweight relative to the
Lehman Brothers Municipal Bond Index in prerefunded bonds detracted somewhat
from performance due to their positioning on the short end of the yield curve.
However, these bonds were purchased at much higher interest rates and therefore,
add considerably to the overall yield of the fund.

The fund's yield-curve positioning also had a significant impact on performance.
When making new purchases, we emphasized the long end of the curve, favoring
bonds with maturities of 20 years or more. This strategy served the fund well as
longer-maturity issues outperformed those with shorter maturities during the
reporting period.

 4


The fund remained well diversified across the major sectors of the municipal
market. As of the close of the period, general purpose, hospital and wholesale
electric bonds represented the fund's largest sector weightings.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

                                                                               9


Expense Example

As a shareholder of the Fund, you incur two types of costs : (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and C Shares;
and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 4/1/06 - 9/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                              11


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund and changes made
in the Fund's portfolio management team over time. The Fund discloses
information about its portfolio management team members and their experience in
its prospectus. The trustees also discuss certain other services which are
provided on a cost-reimbursement basis by the investment adviser or its
affiliates to the Van Kampen funds including certain accounting, administrative
and legal services. The Board has determined that the nature, extent and quality
of the services provided by the investment adviser support its decision to
approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

 12


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              13

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Municipal Income Fund (the "Fund") is organized as a series of the
Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a
diversified open-end management investment company under the Investment Company
Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to
provide a high level of current income exempt from federal income tax,
consistent with preservation of capital. The Fund commenced investment
operations on August 1, 1990. The Fund offers Class A Shares, Class B Shares,
Class C Shares and Class I Shares. Each class of shares differs by its initial
sales load, contingent deferred sales charges, the allocation of class-specific
expenses and voting rights on the matters affecting a single class.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. The Fund
may purchase and sell securities on a "when-issued" or "delayed delivery" basis,
with settlement to occur at a later date. The value of the security so purchased
is subject to market fluctuations during this period. The Fund will segregate
assets with the custodian having an aggregate value at least equal to the amount
of the when-issued or delayed delivery purchase commitments until payment is
made. At September 30, 2006, the Fund had $1,496,809 of when-issued and delayed
delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

and to distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. During the current fiscal year, the Fund utilized capital losses carried
forward of $898,417. At September 30, 2006, the Fund had an accumulated capital
loss carryforward for tax purposes of $21,157,577, which will expire according
to the following schedule.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and gains on futures transactions. All
short-term capital gains and a portion of futures gains are included in ordinary
income for tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 was as follows:

    Due to inherent differences in the recognition of income, expenses and
realized gains/ losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities. A permanent book and tax difference related to the
Fund's investment in other regulated investment companies totaling $7,760 was
reclassified from accumulated undistributed net investment income to accumulated
net realized loss. A permanent book and tax difference related to the sale of a
payment-in-kind security totaling $4,525,006 was reclassified from accumulated

net investment income to accumulated net realized loss. Additionally, a
permanent book and tax difference of $33,601 related to book to tax accretion
differences was reclassified from accumulated undistributed net investment
income to accumulated net realized loss.

    As of September 30, 2006, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $   35,026
Undistributed tax-exempt income.............................   6,959,489
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of post-October losses of $10,955,598 which are
not recognized for tax purposes until the first day of the following fiscal year
and gains or losses recognized for tax purposes on open futures transactions on
September 30, 2006.

F. EXPENSE REDUCTIONS During the year ended September 30, 2006, the Fund's
custody fee was reduced by $25,960 as a result of credits earned on cash
balances.

Management (the "Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

    For the year ended September 30, 2006, the Fund recognized expenses of
approximately $14,500 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment Agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the year ended September 30,
2006, the Fund recognized expenses of approximately $98,500 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
September 30, 2006, the Fund recognized expenses of approximately $306,100
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and, to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $184,427 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2006.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund. Benefits under the
retirement plan are payable upon retirement for a ten-year period and are based
upon each trustee's years of service to the Fund. The maximum annual benefit per
trustee under the plan is $2,500.

    For the year ended September 30, 2006, Van Kampen as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $155,900 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $59,800. Sales charges do not represent expenses of the
Fund.

4. REDEMPTION FEE

The Fund assesses a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund. For the year ended September 30,
2006, the Fund received redemption fees of approximately $400, which are
reported as part of "Cost of Shares Repurchased" on the Statement of Changes in
Net Assets. The per share impact from redemption fees paid to the Fund was less
than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $121,665,813 and $115,130,385,
respectively.

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio, to manage the portfolio's effective yield, maturity and duration, or
generate potential gain. All of the Fund's portfolio holdings, including
derivative instruments, are marked to market each day with the change in value
reflected in unrealized appreciation/depreciation. Upon disposition, a realized
gain or loss is recognized accordingly, except when taking delivery of a
security underlying a futures contract. In this instance, the recognition of
gain or loss is postponed until the disposal of the security underlying the
futures contract. Risks may arise as a result of the potential inability of the
counterparties to meet the terms of their contracts.

    Summarized below are the different types of derivative financial instruments
used by the Fund.

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures on U.S. Treasury Notes and
typically closes the contract prior to delivery date. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the year ended September 30, 2006,
were as follows:

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2005...........................      438

Futures Closed..............................................   (1,783)
                                                               ------
Outstanding at September 30, 2006...........................       35

</Table>

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

B. INVERSE FLOATING RATE SECURITIES An inverse floating rate security is one
where the coupon is inversely indexed to a short-term floating interest rate
multiplied by a specific factor. As the floating rate rises, the coupon is
reduced. Conversely, as the floating rate declines, the coupon is increased. The
price of these securities may be more volatile than the price of a comparable
fixed rate security. These instruments are typically used by the Fund to enhance
the yield of the portfolio. These instruments are identified in the Portfolio of
Investments.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $2,456,400 and $208,700
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint
also alleges that the Van Kampen funds paid excessive commissions to Morgan
Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

                                                                              39


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

9. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes--an interpretation
of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes
by prescribing the minimum recognition threshold a tax position must meet before
being recognized in the financial statements. FIN 48 is effective for fiscal
years beginning after December 15, 2006. The impact to the Fund's financial
statements, if any, is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

VAN KAMPEN MUNICIPAL INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Van Kampen Municipal Income Fund

We have audited the accompanying statement of assets and liabilities of Van
Kampen Municipal Income Fund (the "Fund"), including the portfolio of
investments, as of September 30, 2006, and the related statement of operations
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen Municipal Income Fund at September 30, 2006, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended in conformity with U.S. generally
accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,

BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12B-1 PLAN THAN DID
CLASS A SHARES FOR THE FISCAL PERIOD ENDED SEPTEMBER 30, 2006, THE TOTAL
OPERATING EXPENSE RATIO FOR CLASS B SHARES WAS LOWER AND, AS A RESULT, THE
PERFORMANCE OF CLASS B SHARES WAS HIGHER THAN THAT OF CLASS A SHARES. THERE CAN
BE NO ASSURANCE THAT THIS WILL CONTINUE TO OCCUR IN THE FUTURE AS THE MAXIMUM
FEES PAYABLE BY CLASS B SHARES UNDER THE 12B-1 PLAN ARE HIGHER THAN THOSE
PAYABLE BY CLASS A SHARES.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in years one and two and
declining to zero after year five), a contingent deferred sales charge of 1.00
percent for Class C shares in year one and combined Rule 12b-1 fees and service
fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B
and C shares. The since inception and 10-year returns for Class B shares reflect
the conversion of Class B shares into Class A shares eight years after purchase.
The since inception returns for Class C shares reflect the conversion
                                                                               1


of Class C shares into Class A shares ten years after purchase. Class I shares
are available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least $1 million (including 401(k) plans, 457
plans, employer sponsored 403(b) plans, profit sharing and money purchase plans,
defined benefit plans and non-qualified deferred compensation plans), (ii)
fee-based investment programs with assets of at least $1 million and (iii)
institutional clients with assets of at least $1 million. Class I shares are
offered without any sales charges on purchases or sales and do not include
combined Rule 12b-1 fees and service fees. Figures shown above assume
reinvestment of all dividends and capital gains. The fund's adviser has waived
or reimbursed fees and expenses from time to time; absent such
waivers/reimbursements the fund's returns would have been lower. SEC yield is a
calculation for determining the amount of portfolio income, excluding nonincome
items as prescribed by the SEC. The unsubsidized SEC yields reflect some or all
of the expenses that the adviser had voluntarily waived. Yields are subject to
change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The index does not include any expenses,
fees or sales charges, which would lower performance. The index is unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index. Index data source: Lipper Inc.

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data, and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases--the longest stretch of increases in 25 years. At its
September meeting, the Fed again kept its target rate unchanged, and indicated
that any future rate increases would be driven by the weight of economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
funds. Because prevailing interest rates were still at relatively low levels,
investors increasingly sought out lower-quality, higher yielding bonds. The
increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

                                                                               3


PERFORMANCE ANALYSIS

The fund returned 3.91 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.45 percent for the period.

The performance for the four share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the fiscal period ended September 30, 2006, the total
operating expense ratio for Class B shares was lower and, as a result, the
performance of Class B shares was higher than that of Class A shares. There can
be no assurance that this will continue to occur in the future as the maximum
fees payable by Class B shares under the 12b-1 Plan are higher than those
payable by Class A shares.

We sought opportunities to enhance the portfolio's yield, selectively adding
bonds to the portfolio that we believed were both attractively valued and
offered greater future total return prospects. This led us to lower the fund's
exposure to AA rated bonds, investing the proceeds into higher-yielding A and
BBB rated bonds. As a result, the fund was overweighted versus the Lehman
Brothers Municipal Bond Index in BBB and non-rated bonds, which proved
advantageous as this portion of the market outperformed higher-rated bonds.
Despite this shift in credit allocation, however, the fund's overall credit
quality remained high.

The fund's yield-curve positioning also contributed positively to performance.
We emphasized the long end of the fund's investment range, favoring bonds with
maturities of 10 to 15 years, which served the fund well as longer-maturity
issues outperformed those with shorter maturities. It's important to note that
the fund has, by nature, a shorter average maturity than that of the Lehman
Brothers Municipal Bond Index, which is a long-term index, and as such, could
not benefit as much from rising prices on the very long end of the curve. The
fund's comparatively shorter duration (a measure of interest-rate sensitivity)
was also a factor in its underperformance versus the Lehman Brothers Municipal
Bond Index, keeping the fund from more fully participating in the rally later in
the period.

The hospital and tobacco sectors performed particularly well during the period
and the fund's holdings here were additive to performance. The litigation
environment has become favorable for tobacco companies, demand for the

 4


bonds remains strong, and the industry continues to prosper. The fund remained
well diversified across the major sectors of the municipal market. As of the
close of the period, public education, retail electric and general purpose bonds
represented the fund's largest sector weightings.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

As a shareholder of the Fund, you incur two types of costs : (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and C Shares;
and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 4/1/06 - 9/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                              11


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund and changes made
in the Fund's portfolio management team over time. The Fund discloses
information about its portfolio management team members and their experience in
its prospectus. The trustees also discuss certain other services which are
provided on a cost-reimbursement basis by the investment adviser or its
affiliates to the Van Kampen funds including certain accounting, administrative
and legal services. The Board has determined that the nature, extent and quality
of the services provided by the investment adviser support its decision to
approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

 12


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              13

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Intermediate Term Municipal Income Fund (the "Fund") is organized as
a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is
registered as a diversified, open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide investors with a high level of current income
exempt from federal income tax, consistent with preservation of capital. The
Fund commenced investment operations on May 28, 1993. The Fund offers Class A
Shares, Class B Shares, Class C Shares and Class I Shares. Each class of shares
differs by its initial sales load, contingent deferred sales charges, the
allocation of class specific expenses and voting rights on matters affecting a
single class.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services are valued at fair value
using procedures established in good faith by the Board of Trustees. Futures
contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. The Fund
may purchase and sell securities on a "when-issued" or "delayed delivery" basis,
with settlement to occur at a later date. The value of the security so purchased
is subject to market fluctuations during this period. Purchasing securities on
this basis involves a risk that the market value at the time of delivery may be
lower than the agreed upon purchase price resulting in an unrealized loss. The
Fund will segregate assets with the custodian having an aggregate value at least
equal to the amount of the when-issued or delayed delivery purchase commitments
until payment is made. At September 30, 2006, the Fund has $1,536,514 of
when-issued and delayed delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

                                                                              29

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income, if any, to
its shareholders. Therefore, no provision for federal income taxes is required.

    At September 30, 2006, the cost and related gross unrealized appreciation
and depreciation are as follows:

<Table>

                                                                ============
Gross tax unrealized appreciation...........................    $  2,911,616
Gross tax unrealized depreciation...........................         (11,141)
                                                                ------------
Net tax unrealized appreciation on investments..............    $  2,900,475
                                                                ============
</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed at least annually. Distributions from net realized gains for book
purposes may include short term capital gains and gains on futures transactions.
All short-term capital gains and a portion of futures gains are included in
ordinary income for tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 was as follows:

<Table>
<Caption>
                                                                 2006          2005
                                                                      
Distributions paid from:
  Ordinary income...........................................  $  467,011    $  157,902
  Tax-exempt income.........................................   3,880,983     3,880,918
  Long-term capital gain....................................      84,585            --
                                                              ----------    ----------
                                                              $4,432,579    $4,038,820
                                                              ==========    ==========
</Table>

    Due to inherent differences in the recognition of income, expenses, and
realized gains/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting for the 2006 fiscal year have been identified and appropriately
reclassified on the Statement of Assets and Liabilities. Permanent book and tax
differences of $4,607 related to the Fund's investments in other regulated
investment companies have been reclassified from accumulated undistributed net
investment income to accumulated net realized gain. Additionally, a permanent
difference of $1,088 related to book to tax amortization difference was
reclassified from accumulated undistributed net investment income to accumulated
net realized gain.

    As of September 30, 2006, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                             
Undistributed tax-exempt income.............................    $459,602
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of post October losses which are not realized for
tax purposes until the first day of the following fiscal year and gains or
losses recognized for tax purposes on open futures transactions at September 30,
2006.

F. EXPENSE REDUCTIONS During the year ended September 30, 2006, the Fund's
custody fee was reduced by $3,624 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                        % PER ANNUM
                                                             
First $500 million..........................................       .50%
Over $500 million...........................................       .45%
</Table>

    For the year ended September 30, 2006, the Adviser waived $114,579 of its
investment advisory fee. This represents .10% of the Fund's average net assets
for the period. This waiver is voluntary in nature and can be discontinued at
the Adviser's discretion.

    For the year ended September 30, 2006, the Fund recognized expenses of
approximately $3,300 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide services as legal counsel to the Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the year ended September 30,
2006, the Fund recognized expenses of approximately $61,900 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
September 30, 2006, the Fund recognized expenses of approximately $53,200
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund, and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of approximately $124,000
are included in "Other" assets on the Statement of Assets and Liabilities at
September 30, 2006. Appreciation/depreciation and distributions received from
these investments are recorded with an offsetting increase/decrease in the
deferred compensation obligation and do not affect the net asset value of the
Fund. Benefits under the retirement plan are payable

                                                                              31

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio, to manage the portfolio's effective yield, maturity and duration, or
generate potential gain. All of the Fund's portfolio holdings, including
derivative instruments, are marked to market each day with the change in value
reflected in the unrealized appreciation/depreciation. Upon disposition, a
realized gain or loss is recognized accordingly, except when taking delivery of
a security underlying a futures contract. In this instance, the recognition of
gain or loss is postponed until the disposal of the security underlying the
futures contract. Risks may arise as a result of the potential inability of the
counterparties to meet the terms of their contracts.

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in exchange traded futures on U.S. Treasury Securities and
typically closes the contract prior to delivery date. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the year ended September 30, 2006,
were as follows:

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $2,500 for Class
B and Class C Shares, respectively. These amounts may be recovered from future
payments under the distribution plan or CDSC. To the extent the unreimbursed
receivable has been fully recovered, the distribution fee is reduced.

                                                                              33

8. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint
also alleges that the Van Kampen funds paid excessive commissions to Morgan
Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

9. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The impact to the
Fund's financial statements, if any, is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen Intermediate Term
Municipal Income Fund:

    We have audited the accompanying statement of assets and liabilities of Van
Kampen Intermediate Term Municipal Income Fund (the "Fund"), including the
portfolio of investments, as of September 30, 2006, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen Intermediate Term Municipal Income Fund at September 30, 2006, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended in conformity with U.S.
generally accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,

PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT
VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL ADVISOR. INVESTMENT RETURNS AND
PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect its
conversion into Class A shares eight years after purchase. The since inception
returns for Class C shares reflects the conversion of Class C shares into Class
A shares ten years after purchase. Figures shown above assume reinvestment of
all dividends and capital gains. The fund's adviser has waived or reimbursed
fees and expenses from time to time; absent such waivers/reimbursements the
fund's returns would have been lower. SEC yield is a calculation for determining
the amount of portfolio income, excluding non-income items as prescribed by the
SEC. The unsubsidized SEC yields reflect some or all of the expenses that the
adviser had voluntarily waived. Yields are subject to change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The Lehman Brothers NY Municipal Bond Index
tracks the performance of NY issued municipal bonds rated at least Baa or BBB by
Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively
and with maturities of 2 years or greater. Indexes do not include any expenses,
fees or sales charges, which would lower performance. Indexes are unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index. Source for index performance: Lipper, Inc.

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2006

MARKET CONDITIONS

Against the backdrop of strong economic growth, good employment data and
inflationary pressures stemming from rising oil prices, the Federal Open Market
Committee (the "Fed") continued its tightening campaign during the first nine
months of the reporting period, raising the federal funds target rate six times
to 5.25 percent at the end of June. As the months progressed however, economic
growth moderated as consumer spending and housing weakened while inflation
concerns eased, prompting investors to speculate that the Fed would take a break
from rate increases. In August the Fed did pause, ending a two-year run of 17
consecutive rate increases--the longest stretch of increases in 25 years. At its
September meeting, the Fed again kept its target rate unchanged, and indicated
that any future rate increases would be driven by the weight of economic data.

As a result of the improved outlook for the fixed income market, yields on
longer-maturity municipal bonds fell dramatically in latter months of the
reporting year, ultimately ending at the lowest level in decades. Yields on
shorter-maturity municipal bonds, however, moved higher. Accordingly, the slope
of the municipal yield curve flattened as the spread between short-term and
long-term interest rates narrowed.

Demand for municipal bonds continued to be strong during the period. In fact,
inflows into municipal bond funds were 45 percent higher year-to-date through
September than for the same period last year, much of which went into high yield
funds. Because prevailing interest rates were still at relatively low levels,
investors increasingly sought out lower-quality, higher yielding bonds. The
increased demand for high yield bonds led this segment of the market to
considerably outperform high-grade issues. In addition, long-term bonds
continued to earn the best returns, while the short end of the curve posted the
lowest returns as Fed rate increases moved yields in this portion of the curve
higher.

Although municipal bond issuance remained brisk in the last quarter of 2005,
volume declined throughout the remaining months of the period. As of the end of
September, national municipal bond issuance was down 14 percent for 2006. The
reduced supply, coupled with growing demand, further fueled municipal bond
performance.

Consistent with the national trend, municipal bond issuance by the State of New
York declined for the overall period. However, there was still an abundance of
new issue supply as New York continues to be one of the largest issuers of
municipal bonds in the country. The state's economy is largely driven by the

 2


financial world, which has enjoyed a healthy run over the past decade. As such,
the state continues to have a positive credit outlook.

PERFORMANCE ANALYSIS

The fund returned 4.96 percent for the 12 months ended September 30, 2006 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmarks,
the Lehman Brothers Municipal Bond Index returned 4.45 percent and the Lehman
Brothers NY Municipal Bond Index returned 4.38 percent for the period.

The performance for the three share classes varies because each has different
expenses. The fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definitions.

Throughout the reporting period, we sought opportunities to enhance the
portfolio's yield, while still adhering to our quality-driven investment
discipline. We added to the fund's holdings of lower and non-rated issues that
offered favorable characteristics. As a result, the fund was overweighted
relative to the Lehman Brothers New York Municipal Bond Index benchmark in the
non-rated sector, and underweighted in higher-quality bonds. This posture proved
advantageous as lower and non-rated bonds outperformed higher-rated bonds during
the reporting period.

Another strategy that allowed us to capture significant yield was to increase
the fund's holdings of tobacco revenue bonds. Prior to August of 2005, the fund
did not contain any tobacco bonds but we began cautiously purchasing the bonds
as refundings came into the market in New York. The litigation environment has
become quite favorable for tobacco companies, demand for the bonds remains
strong, and the industry continues to prosper. Our decision to increase the
fund's exposure to this sector during the period was especially additive to
performance as valuations have dramatically improved.

The fund also benefited from its yield-curve positioning. We continued to
emphasize the long end of the curve, favoring bonds with maturities of 20 to 40
years. This strategy served the fund well as longer-dated issues outperformed
shorter-maturity bonds. In addition, reflecting our view that interest rates in
the Treasury market would continue to rise, we kept the fund's duration (a
measure of interest-rate sensitivity) slightly shorter than that of the Lehman
Brothers New York Municipal Bond Index. This conservative stance, which we

                                                                               3


implemented by hedging with five- and 10-year Treasury futures, was beneficial
as rates in the taxable market rose throughout the period.

We added to the fund's holdings in the housing and health care sectors, but the
portfolio remained well diversified across the major sectors of the municipal
bond market. As of September 30, 2006, the fund's largest allocations were to
the general purpose, hospital and higher education sectors. The portfolio was
underweight relative to the Lehman Brothers New York Municipal Bond Index in the
transportation sector, which detracted from returns in the last few months of
the period when the sector rallied.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the fund in
the future.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 04/01/06 - 09/30/06.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

*   Expenses are equal to the Fund's annualized expense ratio of 0.74%, 1.49%,
    and 1.44% for Class A, B and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 183/365 (to reflect the
    one-half year period). These ratios reflect an expense waiver.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                               9


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund and changes made
in the Fund's portfolio management team over time. The Fund discloses
information about its portfolio management team members and their experience in
its prospectus. The trustees also discuss certain other services which are
provided on a cost-reimbursement basis by the investment adviser or its
affiliates to the Van Kampen funds including certain accounting, administrative
and legal services. The Board has determined that the nature, extent and quality
of the services provided by the investment adviser support its decision to
approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

 10


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              11

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen New York Tax Free Income Fund (the "Fund") is organized as a series
of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered
as a non-diversified, open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide investors with a high level of current income
exempt from federal, New York State and New York City income taxes, consistent
with preservation of capital. The Fund seeks to achieve its investment objective
by investing at least 80% of its total assets in a portfolio of New York
municipal securities that are rated investment grade at the time of purchase.
The Fund commenced investment operations on July 29, 1994. The Fund offers Class
A Shares, Class B Shares, Class C Shares and Class I Shares. Each class of
shares differs by its initial sales load, contingent deferred sales charges, the
allocation of class-specific expenses and voting rights on matters affecting a
single class. As of September 30, 2006, there have been no sales of Class I
Shares.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Interest rate swaps are valued using market
quotations from brokers. Short-term securities with remaining maturities of 60
days or less are valued at amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At September 30, 2006, the Fund had $1,546,575 of when-issued
or delayed delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
incremental transfer agency costs which are unique to each class of shares.

                                                                              23

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income, if any, to
its shareholders. Therefore, no provision for federal income taxes is required.

    At September 30, 2006, the cost and related gross unrealized appreciation
and depreciation are as follows:

<Table>
                                                           
Cost of investments for tax purposes........................  $114,292,111
                                                              ============
Gross tax unrealized appreciation...........................  $  5,200,124
Gross tax unrealized depreciation...........................        (5,897)
                                                              ------------
Net tax unrealized appreciation on investments..............  $  5,194,227
                                                              ============
</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and gains on futures transactions. All
short-term capital gains and a portion of futures gains are included as ordinary
income for tax purposes.

    The tax character of distributions paid during the years ended September 30,
2006 and 2005 were as follows:

<Table>
<Caption>
                                                                 2006          2005
                                                                      
Distributions paid from:
  Ordinary income...........................................  $  140,635    $      384
  Tax-exempt income.........................................   4,392,841     4,114,874
  Long-term capital gain....................................   2,171,980           -0-
                                                              ----------    ----------
                                                              $6,705,456    $4,115,258
                                                              ==========    ==========
</Table>

    Due to inherent differences in the recognition of income, expenses, and
realized gains/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities. Permanent book and tax differences relating to the
Fund's investment in other regulated investment companies totaling $2,281 was
reclassified from accumulated undistributed net investment income to accumulated
net realized gain.

    As of September 30, 2006, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $  7,306
Undistributed tax-exempt income.............................   622,012
Undistributed long-term capital gain........................    91,886
</Table>

    Net realized gains and losses may differ for financial reporting and tax
purposes primarily as a result of gains and losses recognized for tax purposes
on open futures transactions on September 30, 2006.

F. EXPENSE REDUCTION During the year ended September 30, 2006, the Fund's
custody fee was reduced by $3,982 as a result of credit earned on cash balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                      % PER ANNUM
                                                           
First $500 million..........................................    .470%
Over $500 million...........................................    .445%
</Table>

    For the year ended September 30, 2006, the Adviser voluntarily waived
$298,224 of its investment advisory fees. This represents .25% of its average
net assets for the period. This waiver is voluntary and can be discontinued at
any time.

    For the year ended September 30, 2006, the Fund recognized expenses of
approximately $7,500 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is a partner of such firm and he and his law firm provide legal services as
counsel to the Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the year ended September 30,
2006, the Fund recognized expenses of approximately $48,700 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
September 30, 2006, the Fund recognized expenses of approximately $49,400
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $74,047 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2006.

                                                                              25

Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund. Benefits under the
retirement plan are payable upon retirement for a ten-year period and are based
upon each trustee's years of service to the Fund. The maximum annual benefit per
trustee under the plan is $2,500.

    For the year ended September 30, 2006, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $33,400 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $47,600. Sales charges do not represent expenses of the
Fund.

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

6. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund may use derivative instruments for a variety of reasons such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective maturity and duration. All of
the Fund's portfolio holdings, including derivative instruments, are marked to
market each day with the change in value reflected in the unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract.

    Summarized below are the different types of derivative financial instruments
used by the Fund.

A. FUTURES CONTRACTS During the period, the Fund invested in futures contracts,
a type of derivative investment. A futures contract is an agreement involving
the delivery of a particular asset on a specified future date at an agreed upon
price. The Fund generally invests in exchange traded futures contracts on U.S.
Treasury Bonds or Notes for duration and risk management purposes and typically
closes the contract prior to the delivery date. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to percentage of the contract amount with either a future commission
merchant pursuant to rules and regulations promulgated in the 1940 Act, as
amended, or with its custodian in an account in the broker's name. This amount
is known as initial margin. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract the (variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the year ended September 30, 2006 are
as follows:

<Table>

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2005...........................     237
Futures Opened..............................................     593
Futures Closed..............................................    (801)
                                                                ----
Outstanding at September 30, 2006...........................      29
                                                                ====
</Table>

B. INVERSE FLOATING RATE SECURITIES An inverse floating rate security is one
where the coupon is inversely indexed to a short-term floating interest rate
multiplied by a specific factor. As the floating rate rises, the coupon is
reduced. Conversely, as the floating rate declines, the coupon is increased. The
price of these securities may be more volatile than the price of a comparable
fixed rate security. These instruments are typically used by the Fund to enhance
the yield of the portfolio. These securities are identified on the Portfolio of
Investments.

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Fund's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Fund's agreement with

                                                                              27


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

a counterparty to pay, in the future, a fixed or variable rate payment in
exchange for the counterparty paying the Fund a variable or fixed rate payment,
the accruals for which would begin at a specified date in the future (the
"effective date"). The amount of the payment obligation is based on the notional
amount of the forward swap contract and the termination date of the swap (which
is akin to a bond's maturity). The value of the Fund's swap commitment would
increase or decrease based primarily on the extent to which long-term interest
rates for bonds having a maturity of the swap's termination date increases or
decreases. The Fund may terminate a swap contract prior to the effective date,
at which point a realized gain or loss is recognized. When a forward swap is
terminated, it ordinarily does not involve the delivery of securities or other
underlying assets or principal, but rather is settled in cash on a net basis.
The Fund intends, but is not obligated, to terminate its forward swaps before
the effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Fund upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of the Fund with a value approximately equal to the amount of any
unrealized gain. Reciprocally, when the Fund has an unrealized loss on a swap
contract, the Fund has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash, if any, for segregating
purposes is shown on the Statement of Assets and Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $79,200 and $0 for
Class B and Class C Shares, respectively. These amounts may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. LEGAL MATTERS

The Adviser and certain affiliates of the Adviser are named as defendants in a
derivative action which additionally names as defendants certain individual
trustees of certain Van Kampen funds. The named investment companies, including
the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of Van Kampen funds. The complaint

 28


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2006 continued

also alleges that the Van Kampen funds paid excessive commissions to Morgan
Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

9. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

10. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The impact to the
Fund's financial statements, if any, is currently being assessed.

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

                                                                              29


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen New York Tax Free Income
Fund:

    We have audited the accompanying statement of assets and liabilities of Van
Kampen New York Tax Free Income Fund (the "Fund"), including the portfolio of
investments, as of September 30, 2006, and the related statement of operations
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of September 30, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen New York Tax Free Income Fund at September 30, 2006, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for each
of the five years in the period then ended in conformity with U.S. generally
accepted accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than December 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,
NY 10019-6064.

                          AUDIT AND NON-AUDIT SERVICES
                       PRE-APPROVAL POLICY AND PROCEDURES
                                     OF THE
                                VAN KAMPEN FUNDS

              AS ADOPTED JULY 23, 2003 AND AMENDED MAY 26, 2004(1)

1.   STATEMENT OF PRINCIPLES

     The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.(2)

     The SEC has issued rules specifying the types of services that an
independent auditor may not provide to its audit client, as well as the audit
committee's administration of the engagement of the independent auditor. The
SEC's rules establish two different approaches to pre-approving services, which
the SEC considers to be equally valid. Proposed services either: may be
pre-approved without consideration of specific case-by-case services by the
Audit Committee ("general pre-approval"); or require the specific pre-approval
of the Audit Committee ("specific pre-approval"). The Audit Committee believes
that the combination of these two approaches in this Policy will result in an
effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

     For both types of pre-approval, the Audit Committee will consider whether
such services are consistent with the SEC's rules on auditor independence. The
Audit Committee will also consider whether the Independent Auditors are best
positioned to provide the most effective and efficient services, for reasons
such as its familiarity with the Fund's business, people, culture, accounting
systems, risk profile and other factors, and whether the service might enhance
the Fund's ability to manage or control risk or improve audit quality. All such
factors will be considered as a whole, and no one factor should necessarily be
determinative.

     The Audit Committee is also mindful of the relationship between fees for
audit and non-audit services in deciding whether to pre-approve any such
services and may determine for each fiscal year, the appropriate ratio between
the total amount of fees for Audit, Audit-related and Tax services for the Fund
(including any Audit-related or Tax service fees for Covered Entities that were
subject to pre-approval), and the total amount of fees for certain permissible
non-audit services classified as All Other services for the Fund (including any
such services for Covered Entities subject to pre-approval).

     The appendices to this Policy describe the Audit, Audit-related, Tax and
All Other services that have the general pre-approval of the Audit Committee.
The term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval from the Audit Committee. The Audit Committee will add to or
subtract from the list of general pre-approved services from time to time, based
on subsequent determinations.

     The purpose of this Policy is to set forth the policy and procedures by
which the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

- ----------
(1)  This Joint Audit Committee Audit and Non-Audit Services Pre-Approval Policy
     and Procedures (the "Policy"), amended as of the date above, supercedes and
     replaces all prior versions that may have been amended from time to time.

(2)  Terms used in this Policy and not otherwise defined herein shall have the
     meanings as defined in the Joint Audit Committee Charter.


     The Fund's Independent Auditors have reviewed this Policy and believes that
implementation of the Policy will not adversely affect the Independent Auditors'
independence.

2.   DELEGATION

     As provided in the Act and the SEC's rules, the Audit Committee may
delegate either type of pre-approval authority to one or more of its members.
The member to whom such authority is delegated must report, for informational
purposes only, any pre-approval decisions to the Audit Committee at its next
scheduled meeting.

3.   AUDIT SERVICES

     The annual Audit services engagement terms and fees are subject to the
specific pre-approval of the Audit Committee. Audit services include the annual
financial statement audit and other procedures required to be performed by the
Independent Auditors to be able to form an opinion on the Fund's financial
statements. These other procedures include information systems and procedural
reviews and testing performed in order to understand and place reliance on the
systems of internal control, and consultations relating to the audit. The Audit
Committee will monitor the Audit services engagement as necessary, but no less
than on a quarterly basis, and will also approve, if necessary, any changes in
terms, conditions and fees resulting from changes in audit scope, Fund structure
or other items.

     In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

     The Audit Committee has pre-approved the Audit services in Appendix B.1.
All other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

4.   AUDIT-RELATED SERVICES

     Audit-related services are assurance and related services that are
reasonably related to the performance of the audit or review of the Fund's
financial statements or, to the extent they are Covered Services, the Covered
Entities' financial statements, or that are traditionally performed by the
Independent Auditors. Because the Audit Committee believes that the provision of
Audit-related services does not impair the independence of the auditor and is
consistent with the SEC's rules on auditor independence, the Audit Committee may
grant general pre-approval to Audit-related services. Audit-related services
include, among others, accounting consultations related to accounting, financial
reporting or disclosure matters not classified as "Audit services"; assistance
with understanding and implementing new accounting and financial reporting
guidance from rulemaking authorities; agreed-upon or expanded audit procedures
related to accounting and/or billing records required to respond to or comply
with financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements under Forms N-SAR and/or N-CSR.

     The Audit Committee has pre-approved the Audit-related services in Appendix
B.2. All other Audit-related services not listed in Appendix B.2 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

5.   TAX SERVICES

     The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services. Hence, the Audit Committee believes it may grant
general pre-approval to those Tax services that have historically been provided
by the Independent Auditors, that the Audit Committee has reviewed and believes
would not impair the independence of the Independent Auditors, and that are
consistent with the SEC's rules on auditor independence. The Audit Committee
will not permit the retention of the



Independent Auditors in connection with a transaction initially recommended by
the Independent Auditors, the sole business purpose of which may be tax
avoidance and the tax treatment of which may not be supported in the Internal
Revenue Code and related regulations. The Audit Committee will consult with
Director of Tax or outside counsel to determine that the tax planning and
reporting positions are consistent with this policy.

     Pursuant to the preceding paragraph, the Audit Committee has pre-approved
the Tax Services in Appendix B.3. All Tax services involving large and complex
transactions not listed in Appendix B.3 must be specifically pre-approved by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
has been delegated), including tax services proposed to be provided by the
Independent Auditors to any executive officer or trustee/director/managing
general partner of the Fund, in his or her individual capacity, where such
services are paid for by the Fund (generally applicable only to internally
managed investment companies).

6.   ALL OTHER SERVICES

     The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

     The Audit Committee has pre-approved the All Other services in Appendix
B.4. Permissible All Other services not listed in Appendix B.4 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

     A list of the SEC's prohibited non-audit services is attached to this
policy as Appendix B.5. The SEC's rules and relevant guidance should be
consulted to determine the precise definitions of these services and the
applicability of exceptions to certain of the prohibitions.

7.   PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

     Pre-approval fee levels or budgeted amounts for all services to be provided
by the Independent Auditors will be established annually by the Audit Committee.
Any proposed services exceeding these levels or amounts will require specific
pre-approval by the Audit Committee. The Audit Committee is mindful of the
overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services. For each fiscal year, the Audit
Committee may determine the appropriate ratio between the total amount of fees
for Audit, Audit-related, and Tax services for the Fund (including any
Audit-related or Tax services fees for Covered Entities subject to
pre-approval), and the total amount of fees for certain permissible non-audit
services classified as All Other services for the Fund (including any such
services for Covered Entities subject to pre-approval).

8.   PROCEDURES

     All requests or applications for services to be provided by the Independent
Auditors that do not require specific approval by the Audit Committee will be
submitted to the Fund's Chief Financial Officer and must include a detailed
description of the services to be rendered. The Fund's Chief Financial Officer
will determine whether such services are included within the list of services
that have received the general pre-approval of the Audit Committee. The Audit
Committee will be informed on a timely basis of any such services rendered by
the Independent Auditors. Requests or applications to provide services that
require specific approval by the Audit Committee will be submitted to the Audit
Committee by both the Independent Auditors and the Fund's Chief Financial
Officer, and must include a joint statement as to whether, in their view, the
request or application is consistent with the SEC's rules on auditor
independence.

     The Audit Committee has designated the Fund's Chief Financial Officer to
monitor the performance of all services provided by the Independent Auditors and
to determine whether such services are in compliance with this Policy. The
Fund's Chief Financial Officer will report to the Audit Committee on a periodic
basis on the results of its monitoring. A sample report is included as Appendix
B.7. Both the Fund's Chief Financial Officer and management will immediately
report to the chairman of the Audit Committee any breach of this Policy that
comes to the attention of the Fund's Chief Financial Officer or any member of
management.



9.   ADDITIONAL REQUIREMENTS

     The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.

10.  COVERED ENTITIES

     Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities
