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

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. Figures shown above assume reinvestment of all dividends
and capital gains. SEC yield is a calculation for determining the amount of
portfolio income, excluding nonincome 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.

Fund Report

FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005

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

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (the difference between short and longer-term yields)
flattened and the long end of the municipal market handily outperformed the
shorter end.

The municipal market in total posted positive returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

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.

One of our primary strategies in managing the fund was to take advantage of
compelling opportunities in the 25- to 30-year segment of the market. We focused
here on purchasing securities with premium (that is, above-market) coupons and
moderate interest rate sensitivity. Our purchases of these securities were
funded by the proceeds of sales of several shorter-maturity positions, many of
which had been refunded during the period. This was part of our ongoing strategy
of positioning the fund for an environment of rising short-term interest rates
by limiting the fund's exposure to that segment of the market.

In terms of purchases, we continued to favor the essential services segments of
the market, such as education and transportation. In turn, we avoided the
housing sector out of concerns about those bonds' structural characteristics. We
also avoided zero coupon bonds. The fund remained well diversified
geographically, with no one state or region dominating the portfolio. Many of
our purchases were from states with either high taxes, and thus strong ongoing
demand for the bonds, or a lack of dual tax-exempt status, such as Illinois.
Because the fund focuses on bonds that offer the credit enhancement of
insurance, the entire portfolio was rated AAA at the close of the period.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

HOUSEHOLDING NOTICE

       To reduce fund expenses, the fund attempts to eliminate duplicate
       mailings to the same address. The fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1
       Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor
       Services has received your instructions, we will begin sending individual
       copies for each account within 30 days.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD

       The fund's policies and procedures with respect to the voting of proxies
       relating to the fund's portfolio securities and information on how the
       fund voted proxies relating to portfolio securities during the most
       recent twelve-month period ended June 30 is available without charge,
       upon request, 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
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 10/01/04 - 3/31/05.

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
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.

</Table>

*   Expenses are equal to the Fund's annualized expense ratio of 0.88%, 1.63%,
    and 1.63% for Class A, B, and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 182/365 (to reflect the
    one-half year period).

Assumes all dividends and distributions were reinvested.

(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 4.27% to 4.30%. Per share,
    ratios and supplemental data for the 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 purchases.
    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.

(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 3.50% to 3.53%. Per share,
    ratios and supplemental data for the 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 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.

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED)

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 Fund registered Class I Shares on August 31, 2004. There were
no sales of Class I Shares for the period ended March 31, 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 March 31, 2005, the Fund had $33,336,090 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

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

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

<Table>

Undistributed ordinary income...............................  $1,832,228
Undistributed long-term capital gain........................   9,263,391
</Table>

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

G. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's
custody fee was reduced by $11,729 as a result of credits earned on cash
balances.

                                                                              33

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...........................................     0.450
</Table>

    For the six months ended March 31, 2005, the Fund recognized expenses of
approximately $28,300 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 Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $51,900 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, in 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 six months ended
March 31, 2005, the Fund recognized expenses of approximately $296,400,
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 $229,011 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2005.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligations and do not affect the net asset value of the Fund. Benefits under
the retirement plan are payable upon retirement for a ten-year period and are
based upon each trustee's years of service to the Fund. The maximum annual
benefit per trustee under the plan is $2,500.

5. 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

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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.

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 six months ended March 31, 2005,
were as follows:

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.

6. 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 $1,573,500 and $59,800
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 six months ended March 31, 2005, are payments
retained by Van Kampen of approximately $362,300 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $45,300.

7. 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.

    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

 38


VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

the consolidated complaint described in the preceding paragraph. Plaintiff has
sought leave to file a second amended derivative compliant 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 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.

8. INDEMNIFICATIONS

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

                                                                              39

Fund Report

FOR THE 6-MONTH PERIOD ENDED MARCH 31, 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 Dennis S. Pietrzak and James D. Phillips, Executive
Directors of the Adviser.

MARKET CONDITIONS

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (the difference between short and longer-term yields)
flattened and the long end of the municipal market handily outperformed the
shorter end.

The municipal market in total posted positive returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

PERFORMANCE ANALYSIS

The fund returned 3.98 percent for the six months ended March 31, 2005 (Class A
shares, unadjusted for sales charge). In comparison, the fund's benchmark index,
the Lehman Brothers Municipal Bond Index, returned 1.21 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.

The fund's relative outperformance was largely the result of its focus on
higher-yielding municipal bonds. Despite ongoing increases to the federal funds
target rate, yields on intermediate- and longer-maturity bonds remained
relatively low for much of the period. As a result, investors hungry for yield
income bid up the prices of higher-yielding securities over the period. This
trend was a benefit to the fund, especially given its benchmark's lack of
exposure to non-rated securities.

During the first quarter of 2005, the fund also benefited from taking an initial
limited position in tobacco bonds. We added these securities based on our
evaluation of reduced litigation risk for the industry just prior to favorable
developments in the federal courts. The sector appreciated early in 2005, and
the portfolio gained as a result of its exposure.

Not all of the fund's positions were so favorable. Based on our analysis of
interest rates, the fund's duration (a measure of interest-rate exposure) was
below that of its benchmark index over the period. While this stance supported
returns in those weeks when rates rose, it was not uniformly helpful across the
period.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

HOUSEHOLDING NOTICE

       To reduce fund expenses, the fund attempts to eliminate duplicate
       mailings to the same address. The fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1
       Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor
       Services has received your instructions, we will begin sending individual
       copies for each account within 30 days.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD

       The fund's policies and procedures with respect to the voting of proxies
       relating to the fund's portfolio securities and information on how the
       fund voted proxies relating to portfolio securities during the most
       recent twelve-month period ended June 30 is available without charge,
       upon request, by visiting our website 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
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 10/1/04 - 3/31/05.

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
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.

*   Expenses are equal to the Fund's annualized expense ratio of 0.84%, 1.60%,
    and 1.59% for Class A, B, and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 182/365 (to reflect the
    one-half year period).

PORTFOLIO OF INVESTMENTS -- MARCH 31, 2005 (UNAUDITED) continued

Percentages are calculated as a percentage of net assets.

*   Zero coupon bond

(a) These securities are restricted and may be resold only in transactions
    exempt from registration which are normally those transactions with
    qualified institutional buyers. Restricted securities comprise 11.4% of net
    assets.

(b) Securities purchased on a when-issued or delayed delivery basis.

(c) 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. 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.

(d) The Fund owns 100% of the bond issuance.

(e) Interest is accruing at less than the stated coupon.

(f) Non-income producing security.

(g) This borrower has filed for protection in federal bankruptcy court.

(h) Security is a "step-up" bond where the coupon increases or steps up at a
    predetermined date.

(i) Payment-in-kind security.

(j) Market value is determined in accordance with procedures established in good
    faith by the Board of Trustees.

(k) All or a portion of these securities have been physically segregated in
    connection with open futures contracts.

    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,

    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 -- MARCH 31, 2005 (UNAUDITED)

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 March 31, 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 March 31, 2005, the Fund had $30,480,257 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.

                                                                              43

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

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At September 30, 2004, the Fund had an accumulated capital loss
carryforward for tax purposes of $72,989,958, which will expire according to the
following schedule.

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.

    Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of the deferral of losses related to wash sale
transactions and the capitalization of reorganization and restructuring costs,
and losses recognized for tax purposes but not for book purposes.

F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's
custody fee was reduced by $20,072 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:

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

    For the six months ended March 31, 2005, the Fund recognized expenses of
approximately $6,200 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
legal counsel to the Fund.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $44,600 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses in the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
March 31, 2005, the Fund recognized expenses of approximately $222,300
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 $138,024 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 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.

                                                                              45

5. 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.

                                                                              47


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

    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.

    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 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). 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 six months ended March 31, 2005,
were as follows:

6. 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 $2,710,700 and $325,900
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 six months ended March 31, 2005, are payments
retained by Van Kampen of approximately $816,800 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $38,100.

7. 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.

    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

                                                                              49


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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 later 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.

8. INDEMNIFICATIONS

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

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 3.25 percent for Class A shares, a contingent deferred
sales charge of 3.00 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 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. 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. Source for index performance: Lipper Inc.

Fund Report

FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005

Van Kampen California Insured Tax Free Fund is managed by the Adviser's
Municipal Fixed-Income team.(1) Members of the team include Dennis S. Pietrzak
and John R. Reynoldson, Executive Directors of the Adviser; and Joseph A.
Piraro, Vice President of the Adviser.

MARKET CONDITIONS

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (the difference between short and longer-term yields)
flattened and the long end of the municipal market handily outperformed the
shorter end.

The municipal market in total posted positive returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

From a credit perspective, the state of California has made some positive
strides. The California government's measures to stem current and projected
budget deficits have been met with broad approval by investors. This in turn has
resulted in improved demand for California bonds and a general rise in bond
prices. During the period, the state maintained its position as the leading
issuer of new municipal debt. More than half of the new issuance which came to
market was protected by credit insurance, which was helpful for us as we
attempted to put cash to work.

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.

The fund's performance relative to its benchmark was in large part the result of
its positioning along the yield curve. One of our primary strategies in managing
the fund was to take advantage of compelling opportunities in the 25- to 30-year
segment of the market. We focused here on purchasing securities with premium
(that is, above-market) coupons and moderate interest rate sensitivity. While we
believe these securities offer strong total return potential, they did boost the
fund's exposure during the period to a segment of the California market which
underperformed relative to the broader, national benchmark.

Our purchases of these securities were funded by the proceeds of sales of
several shorter-maturity positions, many of which had been refunded during the
period. This was part of our ongoing strategy of positioning the fund for an
environment of rising short-term interest rates by limiting the fund's exposure
to that segment of the market.

In terms of purchases, we continued to favor the essential services segments of
the market, such as education and transportation. In turn, we avoided the
housing sector out of concerns about those bonds' structural characteristics. We
also avoided zero coupon bonds. This approach resulted in a portfolio that
remained well diversified across the major segments of the California municipal
bond market. Tax districts, public education, higher education, public building
and general purpose represented the portfolio's top exposures. Because the fund
focuses on bonds that offer the credit enhancement of insurance, the entire
portfolio was rated AAA at the close of the period.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

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 10/01/04 - 03/31/05.

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
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.

Percentages are calculated as a percentage of net assets.

*   Zero coupon bond

(a) The Fund owns 100% of the bond issuance.

(b) 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. All of the Trust'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.

(c) These securities are restricted and may be resold only in transactions
    exempt from registration which are normally those transactions with
    qualified institutional buyers. Restricted securities comprise 1.24% of net
    assets.

(d) Security purchased on a when-issued or delayed delivery basis.

(a) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 3.25% 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 purchases.
    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.

(b) The Ratio of Expenses to Average Net Assets does not reflect credits earned
    on cash balances. If these credits were reflected as a reduction of
    expenses, the ratio would decrease by .01% for the year ended September 30,
    2000.

(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 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 4.16% to 4.18%. Per share,
    ratios and supplemental data for periods prior to September 30, 2002 have
    not been restated to reflect this change in presentation.

    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting market discount on fixed income securities. The effect of this

    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 3.39% to 3.41%. Per share,
    ratios and supplemental data for periods prior to September 30, 2002 have

VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED)

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 Shares and Class C Shares commenced on April 30, 1993 and August 13, 1993,
respectively. The Fund registered Class I Shares on September 1, 2004. There
were no sales of Class I Shares for the period ended March 31, 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 accounting principles
generally accepted in the United States of America 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 March 31, 2005, the Fund had $6,079,743 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

                                                                              21

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 year ended September 30,
2004 was as follows:

<Table>

basis were as follows:

Undistributed ordinary income...............................  $      543
Undistributed long-term capital gain........................   1,481,141
</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 six months ended March 31, 2005, the Fund's
custody fee was reduced by $1,583 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

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

Next $150 million...........................................     0.450
Next $250 million...........................................     0.425
Over $500 million...........................................     0.400
</Table>

    For the six months ended March 31, 2005, the Fund recognized expenses of
approximately $8,500 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Accounting Services and Legal Services Agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $26,300 representing Van
Kampen Investment Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, in 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 six months ended
March 31, 2005, the Fund recognized expenses of approximately $54,300
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 $112,160 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 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.

                                                                              23

VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

    For the six months ended March 31, 2005, Van Kampen as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $18,800 and CDSC on redeemed shares of approximately $15,700.
Sales charges do not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $20,468,005 and $16,831,226,
respectively.

5. 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.
At March 31, 2005, there were no distribution expenses incurred by Van Kampen
and not yet reimbursed ("unreimbursed receivable") for Class B and Class C
Shares. Any unreimbursed receivables 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 six months ended March 31, 2005 are payments
retained by Van Kampen of approximately $19,400 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $23,100.

6. 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 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.

    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

 26


VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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 compliant 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 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.

7. 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.

                                                                              27

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. 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.

Fund Report

FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005

Van Kampen 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 Timothy D. Haney, Vice President of the Adviser.

MARKET CONDITIONS

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (the difference between short and longer-term yields)
flattened and the long end of the municipal market handily outperformed the
shorter end.

The municipal market in total posted positive returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

PERFORMANCE ANALYSIS

The fund returned 0.63 percent for the six months ended March 31, 2005 (Class A
shares, unadjusted for sales charge). In comparison, the fund's benchmark index,
Lehman Brothers Municipal Bond Index returned 1.21 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 underperformance relative to its benchmark was largely the result of
its exposure to bonds with maturities in the five- to 10-year range. These
securities were especially hard hit by rising interest rates during the period,
and the fund's above-market exposure meant that it suffered more than did the
broader market benchmark from their poor performance. We trimmed many of these
holdings as part of an ongoing strategy to position the fund for continued
increases in short-term interest rates. This strategy also included adding
selectively to the fund's holdings of bonds with longer maturities but moderate
interest rate characteristics. Finally, we kept the fund's duration (a measure
of overall interest-rate sensitivity) below that of its benchmark.

We continued to focus on relative-value trading between liquid, high-quality
securities to capture relative value opportunities identified by our analysts.
The fund's overall credit exposure remained tilted toward higher-quality
securities, with more than 81 percent of its exposure at the end of the period
in bonds rated AA or better. That said, the portfolio also had approximately 14
percent of its exposure in bonds rated BBB or lower. These positions benefited
from the ongoing outperformance by lower-rated bonds, and were beneficial to the
fund's returns. The fund's portfolio remained well diversified across the major
sectors of the municipal bond market, with its top three sectors at the end of
the period being general purpose, transportation and wholesale electric.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

HOUSEHOLDING NOTICE

       To reduce fund expenses, the fund attempts to eliminate duplicate
       mailings to the same address. The fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1
       Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor
       Services has received your instructions, we will begin sending individual
       copies for each account within 30 days.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD

       The fund's policies and procedures with respect to the voting of proxies
       relating to the fund's portfolio securities and information on how the
       fund voted proxies relating to portfolio securities during the most
       recent twelve-month period ended June 30 is available without charge,
       upon request, 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
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 10/1/04 - 3/31/05.

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
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.

*   Expenses are equal to the Fund's annualized expense ratio of 0.87%, 1.63%,
    and 1.63% for Class A, B, and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 182/365 (to reflect the
    one-half year period).

    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. The price of these securities may be more volatile than the price
    of a comparable fixed rate security. 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.

(d) The Fund owns 100% of the bond issuance.

(e) 144A securities are those which are exempt from registration under Rule 144A
    of the Securities Act of 1933, as amended. These securities may only be
    resold in transactions exempt from registration which are normally those
    transactions with qualified institutional buyers.

(f) Security is a "step-up" bond where the coupon increases or steps up at a
    predetermined date.

(g) This borrower has filed for protection in federal bankruptcy court.

(h) Non-income producing security.

(i) Payment-in-kind security.

(j) Interest is accruing at less than the stated coupon.

    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

    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

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED)

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 and Class C
shares commenced on August 24, 1992 and August 13, 1993, respectively. The Fund
registered Class I Shares on September 1, 2004. There were no sales of Class I
Shares for the period ended March 31, 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.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. The Fund
may purchase and sell securities on a "when-issued" or "delayed delivery" basis,
with settlement to occur at a later date. The value of the security so purchased
is subject to market fluctuations during this period. The Fund will segregate
assets with the custodian having an aggregate value at least equal to the amount
of the when-issued or delayed delivery purchase commitments until payment is
made. At March 31, 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

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At September 30, 2004, the Fund had an accumulated capital loss
carryforward for tax purposes of $27,985,150 which will expire according to the
following schedule.

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 six months ended March 31, 2005, the Fund recognized expenses of
approximately $15,400 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 legal services as legal counsel to the
Fund.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $37,200 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, 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 six months ended
March 31, 2005, the Fund recognized expenses of approximately $166,700
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and, to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $161,615 are included in
"Other" assets on the Statements of Assets and Liabilities at March 31, 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.

whose value is "derived" from the value of an underlying asset, reference rate
or index.

 30


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

    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.

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in futures on U.S. Treasury Notes. 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 six months ended March 31, 2005,
were as follows:

6. 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

                                                                              31


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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 $2,592,900 and $185,900
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 six months ended March 31, 2005, are payments
retained by Van Kampen of approximately $186,700 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $34,800.

7. 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.

    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 compliant 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

 32


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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 the litigation, and no provision has been made in the Fund's
financial statements for the effect, if any, of these matters.

8. INDEMNIFICATIONS

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

                                                                              33

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

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 3.25 percent for Class A shares, a contingent deferred
sales charge of 3.00 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 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. Figures shown above assume
reinvestment of all dividends and capital gains. The fund's adviser has waived
or reimbursed fees and expenses from time to time; absent such
waivers/reimbursements the fund's returns would have been lower. SEC yield is a
calculation for determining the amount of portfolio income, excluding non-
income items as prescribed by the SEC. The subsidized 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 6-MONTH PERIOD ENDED MARCH 31, 2005

Van Kampen Intermediate Term Municipal Income Fund is managed by the Adviser's
Municipal Fixed Income team, which includes Timothy D. Haney, Vice President of
the Adviser.(1)

MARKET CONDITIONS

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (which measures the difference in yields between short
and longer-term yields) flattened and the long end of the municipal market
handily outperformed the shorter end.

The municipal market posted positive overall returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

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 underperformance relative to its benchmark was driven largely by its
emphasis on the short-to-intermediate segment of the market. While this
positioning tends to keep the fund's volatility at a modest level over longer
time periods, it can hamper returns over shorter periods when yields on these
securities rise more rapidly than those of longer-term bonds. That was the
pattern which dominated the market during the review period, and the fund's
returns suffered as a result. In fact, intermediate municipal funds as a group
underperformed their longer-maturity counterparts over the period.

In managing the fund, we continued to focus on 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 in
order to reinvest the proceeds into bonds with greater future potential for
total return. Most of our trading during the six-month period occurred in the
10-to-15 year portion of the market. Our purchases were largely of securities
with 15-year maturities but which had more moderate interest rate exposure.

The fund remained focused on higher-quality securities. As of the end of the
reporting period, approximately 72 percent of the fund's portfolio consisted of
securities rated AA or better. We added selectively to the portfolio's holdings
of bonds rated BBB or lower in situations where our analysts' research showed
sufficiently compelling return opportunity. At the sector level, the fund
remained well diversified across the major segments of the municipal market. At
the end of the period, the three largest sectors represented in the portfolio
were public education, general purpose and public building.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

FOR MORE INFORMATION ABOUT PORTFOLIO HOLDINGS

       Each Van Kampen fund provides a complete schedule of portfolio holdings
       in its semiannual and annual reports within 60 days of the end of the
       fund's second and fourth fiscal quarters by filing the schedule
       electronically with the Securities and Exchange Commission (SEC). The
       semiannual reports are filed on Form N-CSRS and the annual reports are
       filed on Form N-CSR. Van Kampen also delivers the semiannual and annual
       reports to fund shareholders, and makes these reports available on its
       public Web site, www.vankampen.com. In addition to the semiannual and
       annual reports that Van Kampen delivers to shareholders and makes
       available through the Van Kampen public Web site, each fund files a
       complete schedule of portfolio holdings with the SEC for the fund's first
       and third fiscal quarters on Form N-Q. Van Kampen does not deliver the
       reports for the first and third fiscal quarters to shareholders, nor are
       the reports posted to the Van Kampen public Web site. You may, however,
       obtain the Form N-Q filings (as well as the Form N-CSR and N-CSRS
       filings) by accessing the SEC's Web site, http://www.sec.gov. You may

HOUSEHOLDING NOTICE

       To reduce fund expenses, the fund attempts to eliminate duplicate
       mailings to the same address. The fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1
       Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor
       Services has received your instructions, we will begin sending individual
       copies for each account within 30 days.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD

       The fund's policies and procedures with respect to the voting of proxies
       relating to the fund's portfolio securities and information on how the
       fund voted proxies relating to portfolio securities during the most
       recent twelve-month period ended June 30 is available without charge,
       upon request, 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
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 10/1/04 - 3/31/05.

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
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.

</Table>

*   Expenses are equal to the Fund's annualized expense ratio of 0.94%, 0.84%,
    and 1.54% for Class A, B, and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 182/365 (to reflect the
    one-half year period). These expense ratios reflect an expense waiver.

(a) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 3.25% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 0.50% 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 charge was 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.

(b) 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 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.

    include payment of the maximum CDSC of 3%, charged on certain redemptions
    made within one year of purchase and declining to 0% after the fourth year.
    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.

(b) 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 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.

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED)

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 shares commenced on October 19, 1993. The Fund registered Class I
Shares on December 30, 2004. There were no sales of Class I Shares for the
period ended March 31, 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 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 March 31, 2005, the Fund has $2,742,996 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.

                                                                              23


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 March 31, 2005, the cost and related gross unrealized appreciation and
depreciation are as follows:

<Table>

</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 year ended September 30,
2004 was as follows:

<Table>

                                                              $882,058
                                                              ========

basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $157,502
</Table>

F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's
custody fee was reduced by $1,288 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 six months ended March 31, 2005, the Adviser waived $60,680 of its
investment advisory fee. This represents an annualized rate of .10% of its
average daily net assets. This waiver is voluntary in nature and can be
discontinued at the Adviser's discretion.

    For the six months ended March 31, 2005, the Fund recognized expenses of
approximately $7,300 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide services as legal counsel to the Fund.

 24


    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $23,100 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, 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 six months ended
March 31, 2005, the Fund recognized expenses of approximately $25,400,
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 $106,200
are included in "Other" assets on the Statement of Assets and Liabilities at
March 31, 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.

3. CAPITAL TRANSACTIONS

At March 31, 2005, capital aggregated $85,693,034, $17,221,547 and $15,696,351
for Classes A, B and C, respectively. For the six months ended March 31, 2005,

    For the six months ended March 31, 2005, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $10,000 and CDSC on redeemed shares of approximately $21,100.
Sales charges do not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $37,046,404 and $30,158,479 respectively.

5. 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.

                                                                              27


    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 future commission merchant pursuant to rules and
regulations promulgated in the 1940 Act, as amended, or with its custodian in an
account in the broker's name. This amount is known as initial margin. During the
period the futures contract is open, payments are received from or made to the
broker based upon changes in the value of the contract (the variation margin).
The risk of loss associated with a futures contract is in excess of the
variation margin reflected on the Statement of Assets and Liabilities.

    Transactions in futures contracts for the six months ended March 31, 2005,
were as follows:

6. 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.
At March 31, 2005, there were no distribution expenses incurred by Van Kampen
and not yet reimbursed ("unreimbursed receivable") for Class B and Class C
shares, respectively. Any unreimbursed receivable may be recovered from future

 28


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 ended, are payments made to Morgan Stanley DW
Inc., an affiliate of the Adviser, of approximately $16,400.

7. 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.

    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, 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.

8. INDEMNIFICATIONS

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

                                                                              29

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
the amount of portfolio income, excluding non-income items as prescribed by the
SEC. The subsidized SEC yields reflect some or all of the expenses that the
adviser had voluntarily waived. Yields are subject to change.

Fund Report

FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005

Van Kampen New York Tax Free Income Fund is managed by the Adviser's Municipal
Fixed Income team.(1) Members of the team include Dennis S. Pietrzak and John R.
Reynoldson, Executive Directors of the Adviser; and Timothy D. Haney, Vice
President of the Adviser.

MARKET CONDITIONS

The six-month period ended March 31, 2005, was characterized by continued
short-term interest rate increases, and the specter of rising inflation
resulting from record-high crude oil prices. The Federal Open Market Committee
(the "Fed") raised the federal funds target rate 100 basis points during the
period through a series of four, "measured" 0.25 percent tightenings to 2.75
percent by the end of March. Although rates in the short and intermediate areas
of the yield curve shifted upward as the Fed tightened, long-term interest rates
fell as buyers did not seem deterred by the prospect of rising inflation. As a
result, the yield curve (the difference between short and longer-term yields)
flattened and the long end of the municipal market handily outperformed the
shorter end.

The municipal market posted positive overall returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a slightly negative showing. Within the investment-grade segment of the
market, yield differentials between BBB-rated municipals and AAA-rated
securities were flat to slightly wider, though BBB-rated securities still
outperformed high grades due to their higher coupons, while securities rated
below investment grade strongly outperformed as investors sought out their
higher yields.

The Fed's interest rate hikes did not dampen investors' appetites for municipal
bonds, as net inflows into municipal bond funds topped $700 million during the
period. The supply of new issues was modest during the closing months of 2004
(the first half of the period) before soaring in the opening months of 2005 as
long-term issuers rushed to bring securities to market in anticipation of
additional interest rate increases in the near term.

New York continued to be one of the most active markets in the nation for new
issuance during the period, although economic conditions were not uniformly
strong. New York's economy continued to improve, and its credit rating was
upgraded thanks to a guardedly optimistic outlook for New York City's fiscal
health. The city continued to issue Liberty bonds to fund reconstruction efforts
at the site of the World Trade Center. By contrast, the northern part of the
state continued to struggle economically.

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.

One of our key strategies in managing the fund was to position it for rising
interest rates. This approach was largely the result of our analysis of interest
rates, which remained relatively low by historical standards even after rising
from their multi-decade lows earlier. We effected this positioning in two ways.
First, we kept the fund's duration (a measure of interest-rate sensitivity)
below that of its benchmark. Second, to limit the fund's exposure to areas of
the market that would be most likely susceptible to rising rates, we also
trimmed the fund's shorter-maturity bonds. We reinvested the proceeds from those
sales into bonds with premium coupons and maturities between 25 and 30 years. In
addition to offering relatively attractive income streams, these securities
positioned the fund to benefit from any future flattening of the yield curve.

We kept the fund's exposure well diversified across the major sectors of the New
York municipal market. Much of our relative-value trading activity was focused
on selling issues that had been pre-refunded and purchasing more attractive
securities in sectors such as water and sewer and public education. The fund
remained focused on investment-grade securities, with more than 97 percent of
the portfolio rated BBB or higher at the end of the period.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

Expense Example

As a shareholder of the Fund, you incur 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 10/01/04 - 03/31/05.

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
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. Therefore, the second line of the table is useful in
comparing ongoing costs, and will not help you determine the relative total
costs of owning different funds that have transactional costs, such as sales
charges (loads), and redemption fees, or exchange fees.

Percentages are calculated as a percentage of net assets.

(a) Security is a "step-up" bond where the coupon increases or steps up at a
    predetermined date.

(b) 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. 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.

(c) All or a portion of these securities have been physically segregated in
    connection with open futures contracts.

(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 share holder would pay on Fund distributions or the redemptions
    of Fund shares.

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED)

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
March 31, 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.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. 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 March 31, 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, 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. At September 30, 2004, the Fund had an accumulated capital loss
carryforward for tax purposes of $78,198 which will expire on September 30,
2009.

    At March 31, 2005, the cost and related gross unrealized appreciation and
depreciation are as follows:

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 year ended September 30,
2004 was as follows:

    As of September 30, 2004, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $271
</Table>

    Net realized gains and losses may differ for financial reporting purposes
primarily as a result of the deferral of losses relating to wash sale
transactions.

F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's
custody fee was reduced by $881 as a result of credit earned on cash balances.

                                                                              21

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..........................................    0.60%
Over $500 million...........................................    0.50%
</Table>

    For the six months ended March 31, 2005, the Adviser voluntarily waived
$148,518 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 six months ended March 31, 2005, the Fund recognized expenses of
approximately $5,600, 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 Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2005, the Fund recognized expenses of approximately $20,300 representing Van
Kampen Investments or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, in 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 six months ended
March 31, 2005, the Fund recognized expenses of approximately $25,500
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 $59,643 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 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.

whose value is "derived" from the value of an underlying asset, reference rate
or index.

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

    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.

    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 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 six months ended March 31, 2005,
are as follows:

6. 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

                                                                              25


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

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 $446,400 and $2,700 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.

    Included in the fees for the six months ended March 31, 2005, are payments
retained by Van Kampen of approximately $162,900 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $24,300.

7. 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.

    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 compliant 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.

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued

    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.

8. INDEMNIFICATIONS

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

                                                                              27
