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 their
conversion into Class A shares seven years after purchase. The since inception
returns for Class C shares reflect their conversion into Class A shares ten
years after purchase. See footnote 3 in the Notes to Financial Statements for
additional information. 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 12b-1 fees and service fees. Figures shown
above assume reinvestment of
                                                                               1


all dividends and capital gains. SEC yield is a calculation for determining the
amount of portfolio income, excluding non-income items as prescribed by the SEC.
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.

Van Kampen Insured Tax Free Income Fund is managed by the Adviser's Municipal
Fixed Income team.(1) Members of the team include James F. Willison, Managing
Director of the Adviser; Joseph R. Arcieri, Executive Director of the Adviser;
and Joseph A. Piraro, Vice President of the Adviser.

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively benign. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis points increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
rates declined. As a result, the yield curve (which charts the difference
between short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

PERFORMANCE ANALYSIS

The fund underperformed its benchmark, the Lehman Brothers Municipal Bond Index,
for the 12 months ended September 30, 2005, assuming no deduction of applicable
sales charges.

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.

Throughout the period, we followed our long-standing practice of trading between
liquid, high quality securities which our analysis identified as compelling
total return opportunities. Our strategy involves buying bonds when they are
attractively valued, and selling them when they reach our return targets. We
then invest the proceeds into bonds with greater potential for future total
return.

Reflecting our view that rates would move higher and that the yields of
short-term bonds would rise faster than those of long-term bonds, we kept the
overall duration of the fund shorter than that of its benchmark index. (Duration
is a measure of interest rate sensitivity.) Our analysis led us to favor bonds
within the 25- to 30-year segment of the market. In keeping with our
conservative strategy, we favored bonds with premium (above-market) coupons and
more defensive interest rate characteristics. To fund the portfolio's purchases,
we sold bonds with maturities of 10 years and less. Pre-refunded issues figured
prominently among our sales. We were also able to take advantage of refinancing
trends by selling pre-refunded bonds that had appreciated significantly during
the time the fund had held them. A modest position in inverse floaters (about 3
percent of the portfolio as of the end of the reporting period) provided an
additional boost to performance.

Meanwhile, we largely avoided zero coupon bonds because of their volatility.
Increased exposure to zero coupon securities would extend the duration of the
portfolio, and our long-term preference was to manage the portfolio's overall
interest rate exposure more conservatively. This decision tempered the fund's
pace over the period.

We kept the fund well diversified across the major sectors of the municipal
market, with an emphasis on essential services. The abundant issuance of insured
debt provided us with considerable choice and flexibility in constructing the
portfolio during the period. At the end of the period, the largest sectors

 4


represented in the portfolio were public education, water & sewer, airports,
wholesale electric and public building. In contrast, we avoided housing bonds
due to their less attractive structures.

The fund reflected a high degree of geographic diversification as well. That
said, as of the end of reporting period, less than five percent of the fund was
in Louisiana, Alabama and Mississippi, with all exposures in areas spared by
Hurricanes Katrina and Rita. Moreover, we have no significant concerns about the
impact of the storms on our Texas-issued debt (13 percent of the portfolio as of
September 30, 2005).

In addition to sector and geographic diversification, we invested in bonds
insured by a range of companies. This strategy enhanced performance during the
period. While all of these insurers were AAA rated, not all were equally
well-known in the market. In certain cases, the less well-known companies
offered higher yields. As a result, we were able to increase the income of the
portfolio within the strict parameters of our quality criteria.

Reflecting its focus on bonds that offer the credit enhancement of insurance,
the portfolio was rated AAA at the end of the period.

There is no guarantee that any sectors mentioned will continue to perform well
or that securities in such sectors will be held by the Fund in the future.

                                                                               5

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

You may obtain a copy of the fund's Proxy Voting Policy and Procedures without
charge, upon request, by calling toll free (800) 847-2424 or by visiting our Web
site at www.vankampen.com. It is also available on the Securities and Exchange
Commission's Web site at http://www.sec.gov.

You may obtain information regarding how the fund voted proxies relating to
portfolio securities during the most recent twelve-month period ended June 30 by

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 charge on redemptions of Class B and C Shares; 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 cost (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 4/1/05 - 9/30/05.

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. 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 25, 2005, 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. 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, a performance committee of 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 a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its

 12


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

    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting market discount on fixed income securities. The effect of this
    change for the year ended September 30, 2002 was to increase net investment
    income per share by less than $.01, decrease net realized and unrealized
    gains and losses per share by less than $.01, and increase the ratio of net
    investment income to average net assets from 4.27% to 4.30%. Per share,
    ratios and supplemental data for the periods prior to September 30, 2002

    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within eighteen months of purchase. With
    respect to shares purchased prior to December 1, 2004, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005

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 distribution of the
Fund's Class B and Class C Shares commenced on May 3, 1993 and August 13, 1993,
respectively. The distribution of the Fund's Class I shares commenced on August
12, 2005.

    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. 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, 2005, 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.

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.

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,
2005 and 2004 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 difference relating to book to tax
accretion differences totaling $105,272 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 $5,587 was reclassified from accumulated
undistributed net investment income to accumulated net realized gain.

    As of September 30, 2005, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $ 5,035,342
Undistributed long-term capital gain........................   15,304,816
</Table>

    Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of gains or losses recognized for tax purposes on
open futures transactions on September 30, 2005.

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

                                                                              39

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, 2005, the Fund's
custody fee was reduced by $39,384 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

Over $1.5 billion...........................................    .450%
</Table>

    For the year ended September 30, 2005, the Fund recognized expenses of
approximately $62,400 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,
2005, the Fund recognized expenses of approximately $143,400, representing Van
Kampen Investment 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, 2005, the Fund recognized expenses of approximately $579,200,
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 $246,728 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2005.
Appreciation/depreciation and distributions received from these investments are
recorded with

4. REDEMPTION FEES

Effective September 26, 2005, the Fund assesses a 2% redemption fee on the

seven days of purchase. The redemption fee is paid directly to the Fund. For the
period ended September 30, 2005, the Fund did not receive any redemption fees.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $776,593,577 and $809,276,957,
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 has a variety of reasons to use derivative instruments, 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 this instance, 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.

                                                                              43


VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

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
Notes 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, 2005,
were as follows:

</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.

7. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and maintenance of shareholder accounts
with respect to such classes of shares.

    Annual fees under the Plans 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 are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $1,399,800 and $61,600
for Class B and Class C Shares, respectively. This amount may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in the fees for the year ended September 30, 2005, are payments
retained by Van Kampen of approximately $693,500 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $88,200.

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. The consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit 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 proprietary mutual 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
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. Plaintiff has sought leave to file a second amended
derivative complaint that alleges that the Adviser permitted or recklessly
disregarded market timing and late trading in its proprietary mutual funds in
order to increase assets under management and fees. However, pursuant to an
agreement between the parties, the plaintiff's proposed second amended
derivative complaint was withdrawn and the allegations regarding market timing
and late trading asserted therein were filed in a separate complaint and
coordinated with other cases related to market timing that have been centralized
in a federal court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

                                                                              45

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, 2005, 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, 2005, 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, 2005, 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.

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 seven 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. See footnote 3 in the Notes to
Financial Statements for additional information. Figures shown above assume
reinvestment of all dividends and capital gains. SEC yield is a calculation for
determining the amount of portfolio income, excluding non-income items as
prescribed by the SEC. 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.

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2005

Van Kampen Strategic Municipal Income Fund is managed by the Adviser's Municipal
Fixed Income team.(1) Members of the team include Wayne D. Godlin, Managing
Director of the Adviser and James D. Phillips, Executive Director of the
Adviser.

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively stable. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis point increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
rates declined. As a result, the yield curve (which charts the difference
between short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

PERFORMANCE ANALYSIS

The fund returned 7.75 percent for the 12 months ended September 30, 2005 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.05 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.

The fund's outperformance during the period was attributable to a variety of
factors. Relative to the benchmark, the fund held greater exposure to higher
yielding bonds. As a result, the fund was better positioned to benefit from the
dramatic 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.) As
investors sought income, they increasingly favored the high yield sector.
Improving economic and corporate fundamentals and declining defaults further
bolstered the appeal of high yield issues.

While this tightening occurred across many sectors of the market, it was
particularly notable in the health care and special tax district sectors, two
areas which we emphasized during the period. Health care bonds were recognized
by the market for their improving fundamentals and potential to benefit from
demographic trends, while tax district bonds were supported by housing starts
and low mortgage rates. The fund's special facility airport bonds boosted the
fund's income. Generally, these bonds are secured by lease payments from
airlines, while airport authorities have ownership rights to these facilities.

Inverse floaters further enhanced performance. (The yields of inverse floaters
move in opposition with interest rates.) We had initiated positions in these
securities when the yield curve was steeper, thereby locking in higher interest
rates. The fund's inverse floaters appreciated briskly when long-term bonds
rallied.

During the period, we increased exposure to tobacco bonds, specifically master
settlement agreement securities. Through our analysis, we determined that
certain of these bonds might offer compelling risk and reward characteristics.
In particular, we were encouraged by the improving litigation environment for

                                                                               3


tobacco companies. As investors rekindled their interest in the sector, the fund
was well served by its exposure to select master settlement agreement bonds.

Although the fund outperformed the benchmark by a significant margin, not all
areas performed equally well. The fund's multi-family and nursing home bond
generated more muted gains relative to the leading sectors. Moreover, a handful
of individual bonds declined due to company-specific factors.

At the end of the period, the fund's largest sector positions were health care,
life care, special tax districts, air carriers and public facilities. To pursue
income with enhanced stability, the fund blended high yield and high grade
securities. High grade bonds represented approximately 14 percent of the
portfolio as of September 30, 2005.

As we begin the fund's next fiscal year, we remain optimistic. Ongoing economic
growth, stronger corporate balance sheets and declining levels of defaults are
among the factors that underpin our sentiment. That said, this optimism is
grounded in appropriate caution and informed by our exacting research of
individual securities.

There is no guarantee that any sectors mentioned will continue to perform well
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 charge on redemptions of Class B and Class C
Shares; 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 04/01/05 - 09/30/05.

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. 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 25, 2005, 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. 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, a performance committee of 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 a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its

                                                                              11


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.

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting market discount on fixed income securities. The effect of this
    change for the year ended September 30, 2002 was to increase net investment
    income per share by less than $.01, decrease net realized and unrealized
    gains and losses per share by less than $.01 and increase the ratio of net
    investment income to average net assets from 5.95% to 5.99%. Per share,
    ratios and supplemental data for periods prior to September 30, 2002 have
    not been restated to reflect this change in presentation.

    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within eighteen months of purchase. With
    respect to shares purchased prior to December 1, 2004, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005

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 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 distribution of the Fund's Class B and Class C
shares commenced on April 30, 1993 and August 13, 1993, respectively. The Fund
registered Class I Shares on December 30, 2004. There were no sales of Class I
Shares for the period ended September 30, 2005.

    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, 2005, the Fund had $49,056,200 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.

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

                                                                              49

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, 2005, the Fund had an accumulated capital loss
carryforward for tax purposes of $92,093,340 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,
2005 and 2004 were as follows:

<Table>
<Caption>
                                                               2005       2004
                                                                  
Distributions paid from:
  Ordinary income...........................................  $1,843    $115,296
  Long-term capital gain....................................     -0-         -0-
                                                              ------    --------
                                                              $1,843    $115,296

</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 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
$9,854,061 has been reclassified from accumulated net realized loss to capital.
Additionally, permanent book and tax differences relating to the Fund's
investment in other

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

regulated investment companies totaling $3,207, book to tax accretion
differences on bonds sold totaling $18,847, and book to tax accretion
differences totaling $126,671 were reclassified from accumulated undistributed
net investment income to accumulated net realized loss.

    As of September 30, 2005, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $48,591
</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, and
post October losses of $23,710,338 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, 2005, the Fund's
custody fee was reduced by $65,379 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:

First $500 million..........................................     .50%
Over $500 million...........................................     .45%
</Table>

    For the year ended September 30, 2005, the Fund recognized expenses of
approximately $45,700 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

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,
2005, the Fund recognized expenses of approximately $174,800 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,

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 STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

    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 $150,660 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2005.
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.

    During the year ended September 30, 2005, the Adviser voluntarily reimbursed
the Fund $30,000 for losses incurred on the sale of portfolio securities which
resulted from the correction of a compliance violation.

Fund, received commissions on sales of the Fund's Class A shares of
approximately $1,581,300 and CDSC on redeemed shares of approximately $246,100.
Sales charges do not represent expenses of the Fund.

4. REDEMPTION FEE

Effective September 26, 2005, 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
period ended September 30, 2005, the Fund received redemption fees of $14, which
are reported as part of "Cost of Shares Repurchased" in the Statement of Changes
in Net Assets.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $1,214,417,911 and $585,626,384,
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 has a variety of reasons to use derivative instruments, 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
counter parties to meet the terms of their contracts.

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

 54


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

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 futures contracts for the year ended September 30, 2005 are
as follows:

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2004...........................       -0-
Futures Opened..............................................    16,431
Futures Closed..............................................   (16,431)

</Table>

B. INDEXED 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

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and maintenance of shareholder accounts
with respect to such classes of shares.

    Annual fees under the Plans of up to 0.25% of Class A average daily net
assets and up to 1.00% each for Class B and Class C average daily net assets are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $3,134,300 and $557,700
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, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

                                                                              55


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

    Included in the fees for the year ended September 30, 2005, are payments
retained by Van Kampen of approximately $1,900,400 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $83,400.

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. The consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit 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 proprietary mutual 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
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. Plaintiff has sought leave to file second amended
derivative complaint that alleges that the Adviser permitted or recklessly
disregarded market timing and later trading in its proprietary mutual funds in
order to increase assets under management and fees. However, pursuant to an
agreement between the parties, that plaintiff's proposed second amended
derivative complaint was withdrawn and that the allegations regarding market
timing and late trading asserted therein were filed in a separate complaint and
coordinated with other cases related to market timing that have been centralized
in a federal court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

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.

                                                                              57


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, 2005, 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, 2005, 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, 2005, 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.

BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12B-1 PLAN THAN DID
CLASS A SHARES FOR THE FISCAL PERIOD ENDED SEPTEMBER 30, 2005, 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. Effective June 1, 2005, the maximum sales charge for Class A shares
increased to 4.75% from 3.25% and the contingent deferred sales charge for Class
B shares increased to 4.00% in years one and two, 3.00% in year three, 2.50% in
year four, 1.50% in year five and 0.00% in year six and thereafter from 3.00% in
year one, 2.50% in year two, 2.00% in year three, 1.00% in year four and 0.00%
in year five and thereafter. 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 four), 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

conversion of Class B shares into Class A shares six 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. See footnote 3 in the Notes
to Financial Statements for additional information. 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 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 non-income items as prescribed by the SEC.

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2005

Van Kampen California Insured Tax Free Fund is managed by the Adviser's
Municipal Fixed-Income team.(1) Members of the team include Joseph A. Piraro and
Robert J. Stryker, Vice Presidents of the Adviser; and Joseph R. Arcieri,
Executive Director of the Adviser.

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively benign. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis points increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
declined. As a result, the yield curve (which charts the difference between
short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

Although issuance dipped from last year's pace, the State of California remained
the leading issuer of municipal debt for the first nine months of 2005.
Throughout the period, the state made notable progress shoring up its fiscal and
credit conditions. For example, the government's plan to reduce budgetary
deficits has been generally well received. In recognition of the state's
strides, rating agencies upgraded California debt, while increased market
interest resulted in broad price appreciation. However, the outlook for the
state is not entirely unclouded. The governor has struggled with declining
popularity and growing impatience from residents over pace of reforms--factors
which could stall the pace of continued reforms.

PERFORMANCE ANALYSIS

The fund returned 3.96 percent for the 12 months ended September 30, 2005 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.05 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.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the fiscal period ended September 30, 2005, 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.

Throughout the period, we followed our long-standing practice of trading between
liquid, high quality securities which our analysis identified as compelling
total return opportunities. Our strategy involves buying bonds when they are in
our opinion attractively valued, and selling them when they reach our return
targets. We then invest the proceeds into bonds that we believe have greater
potential for future total return.

Reflecting our view that rates would move higher and that the yields of short-
term bonds would rise faster than those of bonds with longer maturities, we kept
the overall duration of the fund shorter than that of its benchmark index.
(Duration is a measure of interest rate sensitivity.) Our analysis led us to
favor bonds within the 25- to 30-year segment of the market. In keeping with our
conservative strategy, we favored bonds with premium (above-market) coupons and
more defensive interest rate characteristics. Although we have high
 4


conviction in the long-term total return potential of these issues, they
increased the fund's exposure to a segment of the California market which
trailed the broader Lehman Brothers Municipal Bond Index during the annual
period. To fund these purchases, we sold bonds with maturities of 10 years and
less. We were also able to take advantage of refinancing trends by selling
pre-refunded bonds that had appreciated significantly during the time the fund
had held them. A modest position in inverse floaters (about 3 percent of the
portfolio as of the end of the reporting period) provided an additional boost to
performance.

Meanwhile, we largely avoided zero coupon bonds because of their volatility.
Increased exposure to zero coupon securities would extend the duration of the
portfolio, and our long-term preference was to manage the portfolio's overall
interest rate exposure more conservatively. This decision tempered the fund's
pace over the period.

We kept the fund well diversified across the major sectors of the California
market, with an emphasis on essential services. The abundant issuance of insured
debt provided us with considerable choice and flexibility in constructing the
portfolio during the period. At the end of the period, the largest sectors
represented in the portfolio were public education, public building, tax
allocation, higher education and general purpose. In contrast, we avoided
housing bonds due to their less attractive structures.

In addition to sector diversification, we invested in bonds insured by a range
of companies. This strategy enhanced performance during the period. While all of
these insurers were AAA rated, not all were equally well-known in the market. In
certain cases, the less well-known companies offered higher yields. As a result,
we were able to increase the income of the portfolio within the strict
parameters of our quality criteria.

Reflecting its focus on bonds that offer the credit enhancement of insurance,
the portfolio was rated AAA at the end of the period.

There is no guarantee that any sectors mentioned will continue to perform well
or that securities in such sectors will be held by the Fund in the future.

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the
       Securities and Exchange Commission's Web site at http://www.sec.gov.

       You may obtain information regarding how the fund voted proxies relating
       to portfolio securities during the most recent twelve-month period ended
       June 30 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.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
cost, including sales charges (loads) on purchase payments of Class A Shares and
contingent deferred sales charge on redemptions of Class B and C Shares; 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 cost (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 04/01/05 - 09/30/05.

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, and $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. 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 25, 2005, 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, a performance committee of 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 a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its

 10


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 CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005

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 distribution of the Fund's Class
B, C and I Shares commenced on April 30, 1993, August 13, 1993 and August 12,
2005 respectively.

    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. 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, 2005, the Fund had $2,093,260 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

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,
2005 and 2004 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 difference relating to the Fund's
investment in other regulated investment companies totaling $2,551 was
reclassified from accumulated undistributed net investment income to accumulated
net realized gain. Additionally, a permanent difference relating to book to tax
accretion differences totaling $2,349 was reclassified from accumulated
undistributed net investment income to accumulated net realized gain.

    As of September 30, 2005, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $   94,762
Undistributed long-term capital gain........................   2,815,951
</Table>

F. INSURANCE EXPENSE 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, 2005, the Fund's
custody fee was reduced by $6,722 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:

<Table>

Next $150 million...........................................     .450%
Next $250 million...........................................     .425%
Over $500 million...........................................     .400%
</Table>

    For the year ended September 30, 2005, the Fund recognized expenses of
approximately $20,800 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,
2005, the Fund recognized expenses of approximately $65,400 representing Van
Kampen Investment 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, 2005, the Fund recognized expenses of approximately $105,200
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
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 $122,000
are included in "Other" assets on the Statement of Assets and Liabilities at
September 30, 2005. 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.

                                                                              27

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 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 has a variety of reasons to use derivative instruments, 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.

    The Fund invests in indexed securities. These instruments are identified in
the Portfolio of Investments. The price of these securities may be more volatile
than the price of a comparable fixed rate security.

    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. These instruments are typically used by
the Fund to enhance the yield of the portfolio.

7. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and maintenance of shareholder accounts
with respect to such classes of shares.

    Annual fees under the Plans 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 are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $6,800 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, any excess 12b-1 fees will be refunded to
the Fund on a quarterly basis.

    Included in the fees for the year ended September 30, 2005 are payments
retained by Van Kampen of approximately $36,200 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $45,800.

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates to

                                                                              31

investors rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit which additionally names as defendants certain
individual Trustees of the 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 proprietary mutual 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
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. Plaintiff has sought leave to file a second amended
derivative complaint that alleges that the Adviser permitted or recklessly
disregarded market timing and late trading in its proprietary mutual funds in
order to increase assets under management and fees. However, pursuant to an
agreement between the parties, the plaintiff's proposed second amended
derivative complaint was withdrawn and that the allegations regarding market
timing and late trading asserted therein were filed in a separate complaint and
coordinated with other cases related to market timing that have been centralized
in a federal court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

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.

VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

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, 2005, 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, 2005, by correspondence with the
custodian. 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, 2005, 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.

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 the
conversion of Class B shares into Class A shares six 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. See footnote 3 in the Notes
to Financial Statements for additional information. 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

Fund Report

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2005

Van Kampen Municipal Income Fund is managed by the Adviser's Municipal Fixed
Income team. Current members of the team include Robert W. Wimmel, Vice
President of the Adviser; James F. Willison, Managing Director of the Adviser;
Joseph R. Arcieri, Executive Director of the Adviser; and Robert J. Stryker,
Vice President of the Adviser.(1)

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively benign. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis points increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
rates declined. As a result, the yield curve (which charts the difference
between short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

PERFORMANCE ANALYSIS

The fund returned 3.78 percent for the 12 months ended September 30, 2005 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.05 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.

Throughout the period, we followed our long-standing practice of trading between
liquid, high quality securities which our analysis identified as compelling
total return opportunities. Our strategy involves buying these bonds when they
are in our opinion attractively valued, and selling them when they reach our
return targets. We then invest the proceeds into bonds we believe have greater
potential for future total return.

Reflecting our view that rates would move higher and that the yields of short-
term bonds would rise faster than those of longer-term bonds, we kept the
overall duration of the fund shorter than that of its benchmark index. (Duration
is a measure of interest rate sensitivity.) Additionally, we constructed the
portfolio according to a "barbell" structure, a strategy which was a significant
positive contributor to performance. Specifically, we emphasized very short-term
bonds and longer-term bonds, while limiting exposure to intermediate-term bonds.
Within the long-term portion of the portfolio, we favored high quality bonds
with more moderate interest-rate characteristics. These bonds performed well as
the yield curve flattened.

Consistent with our quality focus, securities rated AA or better represented
approximately 75 percent of the portfolio at the end of the reporting period.
However, we also found opportunities to enhance the yield of the portfolio by
gradually and selectively adding exposure to higher-yielding BBB rated and non-
rated bonds. These credits accounted for approximately 18 percent of the
portfolio as of September 30, 2005. Here, we focused on the health care sector,
where we found a number of issues which met our stringent criteria. To fund
these purchases, we liquidated positions in insured bonds. This shift benefited
performance as quality spreads tightened, particularly within the non-rated
sector. In contrast, the fund's relative performance was hindered by a lack of
exposure to tobacco revenue bonds, the leading sector for the period.

The fund remained well diversified across the major sectors of the municipal
market. At the end of the period, the largest sectors represented in the
portfolio were general purpose, transportation and wholesale electric.

There is no guarantee that any sectors mentioned will continue to perform well
or that securities in such sectors will be held by the Fund in the future.

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the
       Securities and Exchange Commission's Web site at http://www.sec.gov.

       You may obtain information regarding how the fund voted proxies relating
       to portfolio securities during the most recent twelve-month period ended
       June 30 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 charge on redemptions of Class B and C Shares; 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 cost (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 4/1/05 - 9/30/05.

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. 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 25, 2005, 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. 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, a performance committee of 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 a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its

 12


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

(a) Based on average shares outstanding.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million of more, a CDSC of 1% may be
    imposed on certain redemptions made within eighteen months of purchase. With
    respect to shares purchased prior to December 1, 2004, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

(c) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting market discount on fixed income securities. The effect of this
    change for the year ended September 30, 2002 was to increase net investment
    income per share by $.01, decrease net realized and unrealized gains and
    losses by $.01 and increase the ratio of net investment income to average
    net assets from 4.85% to 4.89%. Per share, ratios and supplemental data for
    periods prior to September 30, 2002 have not been restated to reflect this

    include payment of the maximum CDSC of 1%, charged on certain redemptions
    made within one year of purchase. If the sales charge was included, total
    returns would be lower. These returns include combined Rule 12b-1 fees and
    service fees of up to 1% and do not reflect the deduction of taxes that a
    shareholder would pay on Fund distributions or the redemption of Fund
    shares.

(c) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting market discount on fixed income securities. The effect of this
    change for the year ended September 30, 2002 was to increase net investment
    income per share by $.01, decrease net realized and unrealized gains and
    losses by $.01 and increase the ratio of net investment income to average
    net assets from 4.09% to 4.13%. Per share, ratios and supplemental data for
    periods prior to September 30, 2002 have not been restated to reflect this

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005

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 distribution of the Fund's Class B, Class C
and Class I shares commenced on August 24, 1992, August 13, 1993, and August 12,
2005, respectively.

    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, 2005, the Fund had $3,049,200 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 and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

    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 $5,929,156. At September 30, 2005, the Fund had an accumulated
capital loss carryforward for tax purposes of $22,055,994 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 in ordinary income for
tax purposes.

    The tax character of distributions paid during the years ended September 30,
2005 and 2004 were as follows:

<Table>

                                                                2005        2004
                                                                    
Distribution paid from:
  Ordinary Income...........................................  $117,584    $291,037
  Long-term capital gain....................................       -0-         -0-
                                                              --------    --------
                                                              $117,584    $291,037
                                                              ========    ========
</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 related to the Fund's
investment in other regulated investment companies totaling $3,155 was
reclassified from accumulated undistributed net investment income to accumulated
net realized loss. Additionally, a permanent difference of $130,575 related to
book to tax accretion differences was reclassified from accumulated
undistributed net investment income to accumulated net realized loss.

                                                                              33

Undistributed ordinary income...............................  $106,600
</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, 2005.

F. EXPENSE REDUCTIONS During the year ended September 30, 2005, the Fund's
custody fee was reduced by $15,888 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>

    For the year ended September 30, 2005, the Fund recognized expenses of
approximately $33,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such

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,
2005, the Fund recognized expenses of approximately $91,700, 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

part of "Other" expenses on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,

Liabilities at September 30, 2005. Appreciation/depreciation and distributions

    For the year ended September 30, 2005, Van Kampen as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $82,600 and CDSC on redeemed shares of approximately $52,600.
Sales charges do not represent expenses of the Fund.

4. REDEMPTION FEE

Effective September 26, 2005, 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
period ended September 30, 2005, the Fund did not receive any redemption fees.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $251,131,868 and $275,839,532,
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 has a variety of reasons to use derivative instruments, 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
counter parties to meet the terms of their contracts.

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

                                                                              37


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

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, 2005,
were as follows:

</Table>

B. INDEXED SECURITY 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

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively, the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and the maintenance of shareholder
accounts with respect to such classes of shares.

    Annual fees under the Plans of up to 0.25% of Class A average daily net
assets and up to 1.00% each for Class B and Class C average daily net assets are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $2,516,800 and $190,400
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, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in the fees for the year ended September 30, 2005, are payments
retained by Van Kampen of approximately $366,600 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $66,900.

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. The consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit 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 proprietary mutual 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
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. Plaintiff has sought leave to file a second amended
derivative complaint that alleges that the Adviser permitted or recklessly
disregarded market timing and late trading in its proprietary mutual funds in
order to increase assets under management and fees. However, pursuant to an
agreement between the parties, that plaintiff's proposed second amended
derivative complaint was withdrawn and that the allegations regarding market
timing and late trading asserted therein were filed in a separate complaint and
coordinated with other cases related to market timing that have been centralized
in a federal court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of the litigation, and no provision has been
made in the Fund's financial statements for the effect, if any, of these
matters.

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.

                                                                              39


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, 2005, 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, 2005, 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, 2005, 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.

BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12B-1 PLAN THAN DID
CLASS A SHARES FOR THE FISCAL PERIOD ENDED SEPTEMBER 30, 2005, 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. Effective June 1, 2005, the maximum sales charge for Class A shares
increased to 4.75% from 3.25% and the contingent deferred sales charge for Class
B shares increased to 4.00% in years one and two, 3.00% in year three, 2.50% in
year four, 1.50% in year five and 0.00% in year six and thereafter from 3.00% in
year one, 2.50% in year two, 2.00% in year three, 1.00% in year four and 0.00%
in year five and thereafter. 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 four), 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
                                                                               1


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 six 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. See footnote 3
in the Notes to Financial Statements for additional information. 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 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, 2005

Van Kampen Intermediate Term Municipal Income Fund is managed by the Adviser's
Municipal Fixed Income team(1). Current members of the team include James F.
Willison, Managing Director of the Adviser; Joseph R. Arcieri, Executive
Director of the Adviser and Robert W. Wimmel and Robert J. Stryker, Vice
Presidents of the Adviser.

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively benign. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis point increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
declined. As a result, the yield curve (which charts the difference between
short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

PERFORMANCE ANALYSIS

The fund returned 3.31 percent for the 12 months ended September 30, 2005 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.05 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.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the fiscal period ended September 30, 2005, 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.

Throughout the period, we followed our long-standing practice of trading between
liquid, high quality securities which our analysis identified as compelling
total return opportunities. Our strategy involves buying these bonds when they
are in our opinion attractively valued, and selling them when they reach our
return targets. We then invest the proceeds into bonds that we believe have
greater potential for future total return.

We structured the portfolio to reflect our view that rates would move higher and
that the yields of short-term bonds would rise faster than those of longer-term
bonds. We emphasized very short-term bonds and bonds on the longer end of the
fund's investment horizon, while limiting exposure to intermediate-term bonds.
As the long end of the curve outperformed, this positioning was the main driver
of positive performance for the overall period.

Consistent with our quality focus, securities rated AA or better represented 68
percent of assets at the end of the reporting period. However, we also found
opportunities to enhance the yield of the portfolio by selectively adding
exposure to higher yielding BBB rated and non-rated bonds. These credits
accounted for 22 percent of the portfolio as of September 30, 2005. Here, we
focused on the health care sector, where we found a number of issues which met
our stringent criteria. To fund these purchases, we liquidated positions in
insured bonds. This increased exposure to lower rated credits was of particular
benefit to the fund's total returns as credit quality spreads, particularly non-
rated spreads, tightened dramatically over the past 12 months.

Relative value trading between specialty state bonds also helped returns.
(Specialty state bonds are from states with higher than average state taxes.) We
found occasions to buy newly issued bonds at attractive prices when demand was
low. We held these credits until the supply-demand relationship became more
favorable, and sold them to in-state investors seeking tax-exempt yield.

Intermediate-term bonds were particularly well represented among new issuance,
providing us with a wide pool of securities to choose among. The fund remained
well diversified across the major sectors of the municipal market. At the end of
the period, the largest sectors represented in the portfolio were public
education, general purpose and health care.

There is no guarantee that any sectors mentioned will continue to perform well
or that securities in such sectors will be held by the Fund in the future.

       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the

       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 charge on redemptions of Class B and C Shares; 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 cost (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 4/1/05--09/30/05.

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. 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 25, 2005, 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. 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, a performance committee of 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 a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its

 12


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, 2005

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 (the "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 with two
classes of common shares, Class A and Class B shares. The distribution of the
Fund's Class C and Class I shares commenced on October 19, 1993 and August 12,
2005, respectively.

    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, 2005, the Fund had $546,424 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, 2005 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, 2005, the cost and related gross unrealized appreciation
and depreciation are as follows:

<Table>
                                                           
Cost of investments for tax purposes........................  $117,483,411
                                                              ============
Gross tax unrealized appreciation...........................  $  2,879,812
Gross tax unrealized depreciation...........................      (168,934)
                                                              ------------
Net tax unrealized appreciation on investments..............  $  2,710,878
                                                              ============
</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 in ordinary income for
tax purposes.

    The tax character of distributions paid during the years ended September 30,
2005 and 2004 was as follows:

<Table>
<Caption>
                                                                2005        2004
                                                                    
Distributions paid from:
  Ordinary Income...........................................  $157,902    $444,464
  Long Term Capital Gain....................................        --     437,594
                                                              --------    --------
                                                              $157,902    $882,058
</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 2005 fiscal year have been identified and appropriately
reclassified on the Statement of Assets and Liabilities. For the tax year ended
September 30, 2005, a permanent book and tax difference relating to the Fund's
investment in other regulated investment companies totaling $2,392 was
reclassified from accumulated undistributed net investment income to accumulated
net realized gain. Additionally, a permanent difference of $84 relating to book
to tax amortization differences was reclassified from accumulated undistributed
net investment income to accumulated net realized gain.

    As of September 30, 2005, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $413,786
</Table>

    Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of losses recognized for tax purposes on open
futures contracts at September 30, 2005.

F. EXPENSE REDUCTIONS During the year ended September 30, 2005, the Fund's
custody fee was reduced by $2,731 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, 2005, the Adviser waived $122,315 of its
investment advisory fee. This represents .10% of its 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, 2005, the Fund recognized expenses of
approximately $16,400 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,
2005, the Fund recognized expenses of approximately $55,200, representing Van
Kampen Investment 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, 2005, the Fund recognized expenses of approximately $52,400,
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 approximately $115,500
are included in "Other" assets on the Statement of Assets and Liabilities at
September 30, 2005. 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.

                                                                              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 has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio 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 these instances,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

    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 contracts on U.S. Treasury
Securities and typically closes the contract prior to 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 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, 2005,
were as follows:

7. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively, the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and the maintenance of shareholder
accounts with respect to such classes of shares.

    Annual fees under the Plans 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 are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $4,700 for Class
B and Class C shares, respectively. These amounts may be recovered from future

                                                                              35


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

payments under the distribution plan or CDSC. To the extent the unreimbursed
receivable has been fully recovered, any excess 12b-1 fees will be refunded to
the Fund on a quarterly basis.

    Included in these fees for the year ended September 30, 2005, are payments
retained by Van Kampen of approximately $9,000, and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $31,400.

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. The consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit 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 economic incentives to promote the sale of proprietary
mutual 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 complaint has been coordinated with the consolidated
complaint described in the preceding paragraph. Plaintiff has sought leave to
file a second amended derivative complaint that alleges that the Adviser
permitted or recklessly disregarded market timing and late trading in its
proprietary mutual funds in order to increase assets under management and fees.
However, pursuant to an agreement between the parties, the plaintiff's proposed
second amended derivative complaint was withdrawn and the allegations regarding
market timing and late trading asserted therein were filed in a separate
complaint and coordinated with other cases related to market timing that have
been centralized in a federal court.

    The defendants have moved to dismiss these actions and otherwise intend to
defend them vigorously. While the defendants believe that they have meritorious
defenses, the ultimate outcome of these matters is not presently determinable at
this early stage of litigation, and no provision has been made in the Fund's
financial statements for the effect, if any, of these matters.

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.

                                                                              37


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, 2005, 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, 2005, 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, 2005, 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.

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 seven 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. See footnote 3 in the Notes to Financial
Statements for additional information. 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

FUND REPORT

FOR THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2005

Van Kampen New York Tax Free Income Fund is managed by the Adviser's Municipal
Fixed Income team. Members of the team include Dennis S. Pietrzak, John R.
Reynoldson and Joseph R. Arcieri, Executive Directors of the Adviser.

MARKET CONDITIONS

During the 12-month period ended September 30, 2005, the economy grew at a
moderate pace, with reasonable gains in employment and sustained strength in
consumer spending. Although oil prices soared, core inflation (which excludes
food and energy) remained relatively benign. Continuing with the course it began
in June of 2004, the Federal Open Market Committee (the Fed) raised the federal
funds target rate eight times during the period. Through a "measured pace" of 25
basis points increments, the Fed brought the rate to 3.75 percent at the end of
the reporting period. While the yields of short- and intermediate-term bonds
moved upward in concert with the Fed's actions, the yields of long-term bonds
rates declined. As a result, the yield curve (which charts the difference
between short-term and long-term rates) flattened.

Against this backdrop, total returns across the municipal bond market varied
dramatically, with long maturity bonds outperforming short-term issues by a wide
margin. As investors sought income in an environment of historically low rates,
BBB rated and non-rated bonds significantly outperformed high grade debt, and
credit spreads tightened markedly. Strong and steady flows of new cash into high
yield municipal funds added to the demand for lower rated issues.

Sectors with a preponderance of lower rated credits performed with particular
strength. Tobacco revenue bonds were by far the best performing sector,
supported by overall spread tightening as well as by increasing investor comfort
with tobacco companies' future litigation risk. Health care bonds (hospitals and
long-term care facilities) also fared well, boosted by strong investor demand.
In contrast, housing bonds underperformed as interest rates declined and
prepayment risk increased.

Municipal bond issuance remained robust in 2005, with $310 billion of debt
brought to market in the first nine months of the year, a pace on track to beat
the record issuance of 2003. Refunding activity represented a good portion of
this activity, as issuers sought to refinance higher cost debt at low prevailing
interest rates. Bonds backed by insurance dominated issuance and increased their
market penetration to nearly 60 percent.

The State of New York remained a leading issuer of debt during the period.
Liberty bonds (for the reconstruction of the World Trade Center site) were among
the prominent fundings. The state saw its credit rating improve, due largely to
improvements in New York City's fiscal health. Positive employment data and
stable real estate markets also contributed to a brighter outlook. Economic
conditions were not uniformly strong across the state, however, as the northern
"rust belt" area continued to struggle economically.

PERFORMANCE ANALYSIS

The fund returned 4.29 percent for the 12 months ended September 30, 2005 (Class
A shares, unadjusted for sales charges). In comparison, the fund's benchmark,
the Lehman Brothers Municipal Bond Index, returned 4.05 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.

Throughout the period, we followed our long-standing practice of trading between
liquid, high quality securities which our analysis identified as compelling
total return opportunities. Our strategy involves buying these bonds when they
are attractively valued, and selling them when they reach our return targets. We
then invest the proceeds into bonds with greater potential for future total
return.

We sought to position the fund for rising rates, a strategy which proved
beneficial during the period. We kept the overall duration of the fund shorter
than that of its benchmark index. (Duration is a measure of interest rate
sensitivity.) To limit the fund's exposure to bonds that would be most
vulnerable to rising short-term rates, we sold bonds with maturities of 15 years
and less. Pre-refunded issues also figured prominently among our sales. As
refinancing activity surged, we sold many bonds which had appreciated
significantly during the time the fund had held them. We re-deployed assets into
the 25- to 30-year segment of the market, favoring bonds with premium
(above-market) coupons and more defensive interest rate characteristics. As the
yield curve continued to flatten, these bonds contributed strong performance.

At the end of the reporting period, securities rated BBB or higher accounted for
more than 94 percent of the portfolio. Within the context of our quality focused
approach, we sought opportunities to enhance the fund's exposure to higher
yielding securities. For example, after extensive research, we invested in
long-term investment-grade tobacco revenue bonds (which represented
approximately 5 percent of assets at the end of the period).

The fund was well diversified among the major sectors of the New York municipal
market. At the close of the period, the largest sector representations were
general purpose, health care, water and sewer, public education and

 4


student housing. The fund also established a stake in Liberty bonds during the
period.

There is no guarantee that any sectors mentioned will continue to perform well
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 charge on redemptions of Class B and C Shares; 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 cost (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 04/01/05 - 09/30/05.

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. 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 25, 2005, 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. Finally, the Board considered materials it had received in
approving a change in the advisory fee rate effective November 1, 2004. 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,
 10


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 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, a performance committee of 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

                                                                              11


together by the investment adviser with the oversight of a special ad hoc
committee of the Board. The trustees 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.

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting discount on fixed income securities. The effect of this change for
    the year ended September 30, 2002 was to increase net investment income per
    share by less than $.01, decrease net realized and unrealized gains and
    losses per share by less than $.01 and increase the ratio of net investment
    income to average net assets by .01%. Per share, ratios and supplemental
    data for periods prior to September 30, 2002 have not been restated to
    reflect this change in presentation.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within eighteen months of purchase. With
    respect to shares purchased prior to December 1, 2004, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns do
    include Rule 12b-1 fees of up to .25% and do not reflect the deduction of
    taxes that a shareholder would pay on Fund distributions or the redemptions
    of Fund shares.

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting discount on fixed income securities. The effect of this change for
    the year ended September 30, 2002 was to increase net investment income per
    share by less than $.01, decrease net realized and unrealized gains and
    losses per share by less than $.01 and increase the ratio of net investment
    income to average net assets by .01%. Per share, ratios and supplemental

    include Rule 12b-1 fees of up to 1% and do not reflect the deduction of
    taxes that a shareholder would pay on Fund distributions or the redemption
    of Fund shares.

(c) Certain non-recurring payments were made to Class C Shares, resulting in an
    increase to the Total Return and Ratio of Net Investment Income to Average
    net Assets of .03%.

(d) The Total Return, Ratio of Expenses to average Net Assets and Ratio of Net
    Investment Income to Average Net Assets reflect actual 12b-1 fees of less
    than 1% (See Footnote 7).

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005

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, with three classes of
common shares, Class A, Class B and Class C. The Fund registered Class I Shares
on December 30, 2004. There were no sales of Class I Shares for the period ended
September 30, 2005.

    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. 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
payments is made. At September 30, 2005, the Fund had $1,320,463 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

                                                                              25

and to distribute substantially all of its taxable income, if any, 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 such losses against any future realized capital
gains. During the current fiscal year, the Fund utilized capital losses carried
forward of $78,198.

    At September 30, 2005, the cost and related gross unrealized appreciation
and depreciation are as follows:

<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,
2005 and 2004 was as follows:

<Table>

                                                              2005     2004

  Ordinary Income...........................................  $384    $11,294
  Long-term capital gain....................................   -0-        -0-

                                                              $384    $11,294

</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 $1,502 and
book and tax accretion differences totaling $622 were reclassified from
accumulated undistributed net investment income to accumulated net realized
loss.

    As of September 30, 2005, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                             
Undistributed ordinary income...............................    $   73,859
Undistributed long-term capital gain........................    $2,033,570
</Table>

    Net realized gains and 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, 2005.

F. EXPENSE REDUCTION During the year ended September 30, 2005, the Fund's
custody fee was reduced by $2,454 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..........................................       0.47%
Over $500 million...........................................      0.445%
</Table>

    Effective November 1, 2004, the management fee was reduced from .60% for the
first $500 million, and .50% for any average daily net assets greater than $500
million.

    For the year ended September 30, 2005, the Adviser voluntarily waived
$298,729 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, 2005, the Fund recognized expenses of
approximately $16,200, 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,
2005, the Fund recognized expenses of approximately $47,400, representing Van
Kampen Investment 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, 2005, the Fund recognized expenses of approximately $51,300
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 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 $65,689 are included in
"Other" assets on the Statement of Assets and Liabilities at September 30, 2005.
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

                                                                              27

excluding short-term investments, were $49,501,556 and $48,156,498,
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 has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio or to 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.

    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. 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

 30


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 2005 continued

futures contracts on U.S. Treasury Bonds 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
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 values of the
contract (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, 2005, are
as follows:

B. INDEXED SECURITY 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 in the portfolio of
investments.

7. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and the maintenance of shareholder
accounts with respect to such classes of shares.

    Annual fees under the Plans of up to .25% of Class A average daily net
assets and up to 1.00% each for Class B and Class C average daily net assets are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees and paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $305,000 and $1,000 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, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in the fees for the year ended September 30, 2005, are payments
retained by Van Kampen of approximately $330,700 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $46,200.

                                                                              31

8. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. The consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs. Plaintiffs have
filed a Motion for Leave to file a Supplemental Pleading that would, among other
things, expand the allegations and alleged class.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit 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 proprietary mutual 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
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. However, pursuant to an agreement between the parties, the
plaintiff's proposed second amended derivative complaint was withdrawn and the
allegations regarding market timing and late trading asserted therein were filed
in a separate complaint and coordinated with other cases related to market
timing that have been centralized in a federal court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

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.

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, 2005, 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, 2005, 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, 2005, 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.

Item 2. Code of Ethics.

(a) The Trust has adopted a code of ethics (the "Code of Ethics") that applies
to its principal executive officer, principal financial officer, principal
accounting officer or controller, or persons performing similar functions,
regardless of whether these individuals are employed by the Trust or a third
party.

(b) No information need be disclosed pursuant to this paragraph.

(c) The Trust has amended its Code of Ethics during the period covered by the
shareholder report presented in Item 1 hereto to delete from the end of the
following paragraph on page 2 of the Code the phrase "to the detriment of the
Fund.":

"Each Covered Officer must not use his personal influence or personal
relationship improperly to influence investment decisions or financial reporting
by the Fund whereby the Covered Officer would benefit personally (directly or
indirectly)."

Further, due to personnel changes at the Adviser, the list of Covered Officers
set forth in Exhibit B and the General Counsel designee to whom questions about
the application of the Code should be referred in Exhibit C were amended during
the period. Exhibit B was then amended again in March 2005 and a third time in
August 2005 and a fourth time in September 2005. All four editions of Exhibit B
are attached. Additionally, Exhibit B was amended to remove Mitchell M. Merin as
a covered officer.

(d) Not applicable.

(e) Not applicable.

(f)

      (1)   The Trust's Code of Ethics is attached hereto as Exhibit 12A.

      (2)   Not applicable.

      (3)   Not applicable.

Item 3. Audit Committee Financial Expert.

The Trust's Board of Trustees has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees: Jerry Choate and R. Craig Kennedy. Under applicable
securities laws, a person who is determined to be an audit committee financial
expert will not be deemed an "expert" for any purpose, including without
limitation for the purposes of Section 11 of the Securities Act of 1933, as a
result of being designated or identified as an audit committee financial expert.
The designation or identification of a person as an audit committee financial
expert does not impose on such person any duties, obligations, or liabilities
that are greater than the duties, obligations, and liabilities imposed on such
person as a member of the audit committee and Board of Trustees in the absence
of such designation or identification.

(e)(1) The audit committee's pre-approval policies and procedures are as
follows:

                              JOINT AUDIT COMMITTEE
                          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
would include:

      -     Van Kampen Investments Inc.

      -     Van Kampen Asset Management

      -     Van Kampen Advisors Inc.

      -     Van Kampen Funds Inc.

      -     Van Kampen Investor Services Inc.

      -     Morgan Stanley Investment Management Inc.

      -     Morgan Stanley Trust Company

      -     Morgan Stanley Investment Management Ltd.

      -     Morgan Stanley Investment Management Company

      -     Morgan Stanley Asset & Investment Trust Management Company Ltd.

(e)(2) Beginning with non-audit service contracts entered into on or after May
6, 2003, the audit committee also is required to pre-approve services to Covered
Entities to the extent that the services are determined to have a direct impact
on the operations or financial reporting of the Registrant. 100% of such
services were pre-approved by the audit committee pursuant to the Audit
Committee's pre-approval policies and procedures (included herein).

(f) Not applicable.

(g) See table above.

(h) The audit committee of the Board of Trustees has considered whether the
provision of services other than audit services performed by the auditors to the
Registrant and Covered Entities is compatible with maintaining the auditors'
