Item 1. Reports to Shareholders.

The Trust's semi-annual report transmitted to shareholders pursuant to Rule
30e-1 under the Investment Company Act of 1940 is as follows:

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Insured Tax Free Income Fund performed during the semiannual period. The
       portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the fund's financial statements and a list of fund investments
       as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25
percent for Class A shares and 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.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2004

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

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust with Gross
Domestic Product growth topping 4% in both quarters. While this strength in
output has historically triggered fears of rising interest rates, yields
remained stubbornly low across the municipal curve. These low yields were partly
the result of the continued low levels of observed inflation in the U.S.
economy. Unfortunately, they also reflected continuing weakness in the job
market, which remained soft throughout the period. The soft job numbers, coupled
with persistently low inflation, led the Federal Open Market Committee (the Fed)
to maintain its accommodative stance throughout the period.

In keeping with the general trend for calendar year 2003, the six months under
review saw record levels of issuance as municipalities sought to take advantage
of historically low interest rates. Many cities and states moved to reduce
expenditures by refinancing existing debt and replacing it with lower-yielding
bonds. In other cases, municipalities attempted to meet current and future
funding needs by issuing new debt.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and institutional investor activity slowed as holders of municipal bonds saw
little reason to sell bonds purchased at higher yield levels and reinvest at
historically low yields. However, the period was marked by rising activity among
non-traditional investors such as hedge funds and insurance companies seeking to
take advantage of the perceived attractiveness of municipal bonds relative to
taxable securities. Additionally, investors' search for yield led to significant
outperformance by lower-rated bonds with greater credit risk. Sectors such as
health care, with a preponderance of lower-rated issues, performed particularly
well.

California remained in the municipal spotlight during the period, with many
investors anxiously awaiting the result of the March 2 referendum on
Propositions 57 and 58. These two measures, which voters ultimately approved,
gave the green light to an estimated $15 billion economic-improvement bond
issuance that will begin to come to the market in early June. The passage of
these measures led the major ratings agencies to increase their outlooks (though
not their ratings) for the beleaguered state's bonds, with S&P shifting from

stable to positive and Moody's shifting from negative to stable. This surge in
issuance will at least partially offset the surprising decline in new debt in
the first quarter of 2004, which was one-third lower than the level for the
first quarter of last year. The majority of debt issued by the state for the
entire six-month period offered credit enhancements, with fully two-thirds
coming to market with credit insurance.

PERFORMANCE ANALYSIS

The fund returned 2.57 percent for the six months ended March 31, 2004 (Class A
shares, unadjusted for sales charges), underperforming its benchmark, the Lehman
Brothers Municipal Bond Index. (See table below). Our analysis of the economy
and interest rates indicated that the next major movement in rates was likely to
be upward, which we believed warranted a more defensive positioning. As a
result, we chose to emphasize securities that we believed provided sufficient
return potential and were most likely to hold up well in a rising interest-rate
environment. This approach led us to de-emphasize bonds from the long end of the
yield curve given their high sensitivity to interest rates and low coupons;
instead, we focused on securities with premium coupons from the 18- to 22-year
segment of the market in the belief that these bonds offered the most attractive
risk/reward profile. We also kept the fund's overall duration (a measure of
interest-rate sensitivity) below that of the benchmark. Unfortunately, the
longer segment of the yield curve outperformed strongly during the period, and
our defensive stance hampered performance.

In keeping with the fund's mandate, we maintained our long-term discipline of
only buying bonds with the highest credit ratings. Some of the securities we
purchased during the period carried the backing of XCLA, a relatively new credit
insurer. This company is rated AAA by both Moody's and S&P, and as a result its
bonds are well within the fund's investment universe.

We maintained the portfolio's diversification over the reporting period. The
fund's holdings were spread across the full spectrum of municipal bond-market
sectors in order to limit the risk of over-concentration in any one segment. At
the end of the period, the portfolio's largest sector weightings were public
education at 13.4 percent, followed by wholesale electric at 12.1 percent and
public building at 11.9 percent. We also kept the fund well diversified

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 an

geographically, with an emphasis on maintaining balanced exposure across
higher-yielding specialty states such as California and Florida.

We anticipate that rates will eventually begin to move upward. That being said,
we believe the fund is positioned to continue to provide investors with
attractive income across an array of possible market environments. We will
continue to scour the insured municipal market for attractive investment
opportunities.

(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 one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective November 30, 2003, the Fund's investment adviser, Van
Kampen Investment Advisory Corp. merged into its affiliate, Van Kampen Asset
Management.

    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, 2004, the Fund had $17,743,798 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
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 the Internal Revenue Code applicable to regulated investment companies and to
distribute

                                                                              29

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,
2003 was as follows:

Undistributed ordinary income...............................  $   264,854
Undistributed long-term capital gain........................   11,838,027
</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, 2004, the Fund's
custody fee was reduced by $4,273 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:

AVERAGE DAILY NET ASSETS                                      % PER ANNUM

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

    For the six months ended March 31, 2004, the Fund recognized expenses of
approximately $24,800 representing legal expenses provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is an affiliated person.

    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, 2004, the Fund recognized expenses of approximately $70,300 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, 2004, the Fund recognized expenses of approximately $322,100,
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
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 $223,109 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2004.
Appreciation/ depreciation and distributions received from these investments are

excluding short-term investments, were $167,874,434 and $220,796,086,
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 and to manage

                                                                              33

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, 2004,
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

 34


VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

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 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 $2,125,000 and $65,400
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, 2004, are payments
retained by Van Kampen of approximately $433,500 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $52,100.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid

                                                                              35


VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

excessive commissions to Morgan Stanley DW Inc. in connection with the sales of
the funds. The complaint seeks, among other things, the removal of the current
Trustees of the Van Kampen funds, rescission of the management contracts for the
Van Kampen funds, disgorgement of profits by Morgan Stanley and monetary
damages. This complaint will be coordinated with the consolidated complaint.

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.

       In this report, you'll learn about how your investment in Van Kampen
       Strategic Municipal Income Fund performed during the semiannual period.
       The portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the fund's financial statements and a list of fund investments
       as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

Past performance is no guarantee of future results and current performance may
be lower or higher than the figures shown. For more up-to-date information,
including 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.

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 five), a contingent deferred sales charge of 1.00 percent for Class C
shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25
percent for Class A shares and 1.00 percent for Class B and C shares. The
since-inception and 10-year returns for Class B shares reflect the conversion of
Class B shares into Class A shares seven years after purchase. The since
inception returns for Class C shares reflect the conversion of Class C shares
into Class A shares ten years after purchase. See footnote 3 in the Notes to
Financial Statements for additional information. Figures shown above assume
reinvestment of all dividends and capital gains. SEC yield is a calculation for
determining the amount of portfolio income, excluding non-income items as
prescribed by the SEC. Yields are subject to change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The index is unmanaged and does not include
any sales charges or fees. Such costs would lower performance. It is not
possible to invest directly in an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2004

Van Kampen Strategic Municipal Income Fund is managed by the adviser's Municipal
Fixed Income team. Members of the team include Wayne D. Godlin and Dennis S.
Pietrzak, Executive Directors, and James D. Phillips, Vice President.(1)

MARKET CONDITIONS

Economic growth continued to be positive throughout the reporting period.
Despite this growth, however, the economy failed to produce a significant
increase in job creation and inflation remained low, which led the Fed to
maintain its bias toward keeping interest rates low. As a result, yields
remained low across the entire municipal yield curve.

Early in the reporting period, the market had built-in expectations of Fed
tightening (increasing interest rates) in early 2004. When it became apparent
that higher rates were unlikely to materialize as anticipated, market consensus
reversed, bonds rallied, and credit spreads (the incremental yield difference
between lower- and higher-rated bonds) in the municipal market began to tighten.
The rally continued until March, when the municipal market started to lose
momentum and give up some of its prior gains.

The supply of new municipal bond issuance continued to be very high during the
reporting period. Many municipalities sought to take advantage of historically
low interest rates--either by issuing new debt or by refinancing existing debt
that carried higher rates. At the same time, demand for municipal bonds grew as
investors searching for yield were attracted to the bonds' potential tax
advantages. The high-yield segment of the municipal market generally
outperformed higher-rated bonds, particularly in the latter part of the period,
as investors seemed willing to take on greater credit risk in exchange for
higher yields.

PERFORMANCE ANALYSIS

During the six-month period ended March 31, the fund returned 3.61 percent
(Class A shares, unadjusted for sales charge), outpacing its benchmark, the
Lehman Brothers Municipal Bond Index. (See table below.)

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.

The portfolio's structure is commonly referred to as a "barbell" structure--
where holdings are more heavily weighted in the high- and low-grade sectors of
the credit spectrum. This type of structure offers the dual benefits of
potentially higher yields (from the lower-rated portion) and added balance (from
the lower-risk/higher-rated portion).

In the first three months of the period, the portfolio's holdings in
higher-rated bonds drove the fund's positive performance. This outperformance
was due in part to a decline in the overall supply of higher-rated bonds in the
marketplace, which contributed to a rally in this sector.

In the last three months, however, tightening credit spreads led to stronger
relative performance for high-yield bonds. The fund enjoyed gains as a result,
due to its greater concentration in this segment of the market during the
period. As of March 31, 68 percent of the portfolio's long-term holdings were in
high-yield bonds, down slightly from 74 percent as of September 30, 2003.

Within high-yield, our emphasis on health-care and continuing-care bonds--the
fund's top two sectors--was particularly additive to performance due to spread
tightening in these sectors. Holdings in tax-district bonds also helped boost
fund returns. We continued to focus investments in these and other essential-
services sectors of the municipal market because they tend to be less cyclical
and therefore, less affected by changing economic conditions.

We continued to keep the portfolio highly diversified, and maintained its lower
duration (sensitivity to interest-rate changes) to help minimize interest-rate
risk. Keeping the fund's duration in the target range proved more challenging
during the reporting period; with interest rates so low, it was increasingly
difficult to find higher-coupon bonds to add to the portfolio, which have a
lower duration than low-coupon bonds. A lower duration could serve the fund well
if interest rates do begin to rise.

                                                                               3


Looking ahead, we believe demand for municipal bonds should continue to be
strong--especially if the economy continues to improve and interest rates remain
low. As always, we will pursue our disciplined investment approach, monitoring
the markets carefully for opportunities to add value to the portfolio.

(a) Non-income producing security.

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

(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 15.8% of net
    assets.

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

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

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

(g) Payment-in-kind security.

(h) 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

    interest rate shown represents the current interest rate earned by the Fund
    based on the most recent reset date.

    sales charge (CDSC). On purchases of $1 million or more, 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 of up to .25% and do not reflect the
    deduction of taxes that a shareholder would pay on Fund distributions or the

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective
November 30, 2003, the Fund's investment adviser, Van Kampen Investment Advisory
Corp. merged into its affiliate, Van Kampen Asset Management.

    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.
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, 2004, the Fund had $40,219,055 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
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 the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At September 30, 2003, the Fund had an accumulated capital loss
carryforward for tax purposes of $78,989,131 which expires between September 30,
2004 and September 30, 2011. Of this amount, $9,606,294 will expire on September
30, 2004.

    At March 31, 2004, 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

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,
2003 was as follows:

Undistributed ordinary income...............................  $103,011
</Table>

    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.

    For the six months ended March 31, 2004, the Fund recognized expenses of
approximately $14,800 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is an affiliated person.

    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, 2004, the Fund recognized expenses of approximately $57,200 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 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, 2004, the Fund recognized expenses of approximately $180,100
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
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 $131,937 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2004.
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.

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 0.25% of Class A average daily net
assets and 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 $2,069,200 and $52,000
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in these fees for the six months ended March 31, 2004, are payments
retained by Van Kampen of approximately $484,100 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $36,400.

6. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid excessive commissions to Morgan Stanley DW Inc. in connection with the
sales of the funds. The complaint seeks, among other things, the removal of the
current Trustees of the

                                                                              39


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

Van Kampen funds, rescission of the management contracts for the Van Kampen
funds, disgorgement of profits by Morgan Stanley and monetary damages. This
complaint will be coordinated with the consolidated complaint.

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       California Insured Tax Free Fund performed during the semiannual period.
       The portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the fund's financial statements and a list of fund investments
       as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25
percent for Class A shares and 1.00 percent for Class B and C shares. The since
inception and 10-year returns for Class B shares reflect their 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

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2004

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

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust with Gross
Domestic Product growth topping 4% in both quarters. While this strength in
output has historically triggered fears of rising interest rates, yields
remained stubbornly low across the municipal curve. These low yields were partly
the result of the continued low levels of observed inflation in the U.S.
economy. Unfortunately, they also reflected continuing weakness in the job
market, which remained soft throughout the period. The soft job numbers, coupled
with persistently low inflation, led the Federal Open Market Committee (the Fed)
to maintain its accommodative stance throughout the period.

In keeping with the general trend for calendar year 2003, the six months under
review saw record levels of issuance as municipalities sought to take advantage
of historically low interest rates. Many cities and states moved to reduce
expenditures by refinancing existing debt and replacing it with lower-yielding
bonds. In other cases, municipalities attempted to meet current and future
funding needs by issuing new debt.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and institutional investor activity slowed as holders of municipal bonds saw
little reason to sell bonds purchased at higher yield levels and reinvest at
historically low yields. However, the period was marked by rising activity among
non-traditional investors such as hedge funds and insurance companies seeking to
take advantage of the perceived attractiveness of municipal bonds relative to
taxable securities. Additionally, investors' search for yield led to significant
outperformance by lower-rated bonds with greater credit risk. Sectors such as
health care, with a preponderance of lower-rated issues, performed particularly
well.

California remained in the municipal spotlight during the period, with many
investors anxiously awaiting the result of the March 2nd referendum on
Propositions 57 and 58. These two measures, which voters ultimately approved,
gave the green light to an estimated $15 billion economic-improvement bond
issuance that will begin to come to the market in early June. The passage of
these measures led the major ratings agencies to improve their outlooks (though

(1)Team members may change at any time without notice.

not their ratings) for the beleaguered state's bonds, with S&P shifting from
stable to positive and Moody's shifting from negative to stable. This surge in
issuance will at least partially offset the surprising decline in new debt in
the first quarter of 2004, which was one-third lower than the level for the
first quarter of last year. The majority of debt issued by the state for the
entire six-month period offered credit enhancements, with fully two-thirds
coming to market with credit insurance.

PERFORMANCE ANALYSIS

The fund returned 3.09 percent for the six months ended March 31, 2004 (Class A
shares, unadjusted for sales charges), performing roughly in line with its
benchmark, the Lehman Brothers Municipal Bond Index. (See table below). One of
our primary strategies in managing the fund was to adjust its interest-rate
sensitivity. Our analysis of the economy and interest rates indicated that the
next major movement in rates was likely to be upward, which we believed
warranted a more defensive positioning. As a result, we chose to emphasize
securities that we believed provided sufficient return potential and were most
likely to hold up well in a rising interest-rate environment. This approach led
us to de-emphasize bonds from the long end of the yield curve, given their high
sensitivity to interest rates and low coupons; instead, we focused on securities
with premium coupons from the 18- to 22-year segment of the market in the belief
that these bonds offered the most attractive risk/reward profile. We also kept
the fund's overall duration (a measure of interest-rate sensitivity) below that
of the benchmark.

We funded our purchases of intermediate bonds with the proceeds of sales from
elsewhere in the portfolio. These sales included several of the fund's
intermediate securities, which met our performance targets during the period and
were sold at a profit. The fund also benefited from pre-refundings of several
securities, which helped support the portfolio's net asset value (NAV).

We also maintained the portfolio's diversification over the reporting period.
The fund's holdings were spread across the full spectrum of municipal-bond
market sectors in order to limit the risk of over-concentration in any one
segment. At the end of the period, the portfolio's largest sector weightings
were tax districts at 23 percent, followed by public education at 18 percent and
public building at 15 percent.

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 an
index definition.

We anticipate that rates will eventually begin to move upward. That being said,
we believe the fund is positioned to continue to provide investors with
attractive income across an array of possible market environments. We will
continue to monitor the California market for attractive investment
opportunities.

*   Non-Annualized

(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 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

VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective November 30, 2003, the Fund's investment adviser, Van
Kampen Investment Advisory Corp. merged into its affiliate, Van Kampen Asset
Management.

    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, 2004, the Fund had $1,087,883 of when-issued and
delayed delivery purchase commitment.

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
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 the Internal Revenue Code applicable to regulated investment companies and to
distribute

VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

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 law which
allow it to carry 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, 2003, the Fund had an
accumulated capital loss carryforward for tax purposes of $29,472, which will
expire on September 30, 2011.

    At March 31, 2004, the cost and related gross unrealized appreciation and
depreciation are as follows:

</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, 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,
2003 was as follows:

    As of September 30, 2003, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $6,520
</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, 2004, the Fund's
custody fee was reduced by $675 as a result of credits earned on cash balances.

                                                                              19

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

    For the six months ended March 31, 2004, the Fund recognized expenses of
approximately $5,300 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is an affiliated person.

    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, 2004, the Fund recognized expenses of approximately $26,500 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, 2004, the Fund recognized expenses of approximately $58,400
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
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 $107,434 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2004.
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.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $9,198,093 and $27,843,907, 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, 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

 22


VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

change in value reflected in the unrealized appreciation/depreciation. Upon
disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In this instance,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

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

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

    Transactions in futures contracts for the six months ended March 31, 2004,
were as follows:

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2003...........................     252

Outstanding at March 31, 2004...............................     -0-
                                                                ====
</Table>

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

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 1.00% each of Class B and Class C average daily net assets are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $0 for Class B
and Class C Shares, respectively. These amounts may be recovered from future
payments under

                                                                              23


VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

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, 2004 are payments
retained by Van Kampen of approximately $142,200 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $24,800.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid excessive commissions to Morgan Stanley DW Inc. in connection with the
sales of the funds. The complaint seeks, among other things, the removal of the
current Trustees of the Van Kampen funds, rescission of the management contracts
for the Van Kampen funds, disgorgement of profits by Morgan Stanley and monetary
damages. This complaint will be coordinated with the consolidated complaint.

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Municipal Income Fund performed during the semiannual period. The
       portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the fund's financial statements and a list of fund investments
       as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

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 1.00 percent for Class B and C shares. The since
inception and 10-year returns for Class B shares reflect their 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 is unmanaged and does not include
any sales charges or fees. Such costs would lower performance. It is not
possible to invest directly in an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2004

Van Kampen Municipal Income Fund is managed by the adviser's Municipal Fixed
Income team. Current members of the team include James F. Willison, Managing
Director; Joseph R. Arcieri, Executive Director; and Timothy D. Haney, Vice
President.(1)

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust with Gross
Domestic Product growth topping 4% in both quarters. While this strength in
output has historically triggered fears of rising interest rates, yields
remained low across the municipal curve. These low yields were partly the result
of the continued low levels of observed inflation in the U.S. economy.
Unfortunately, they also reflected continuing weakness in the job market, which
remained soft throughout the period. The soft job numbers, coupled with
persistently low inflation, led the Federal Open Market Committee (the Fed) to
maintain its accommodative stance throughout the period.

In keeping with the general trend for calendar 2003, the six months under review
saw high levels of issuance as municipalities sought to take advantage of
historically low interest rates. Many cities and states moved to reduce
expenditures by refinancing existing debt and replacing it with lower-yielding
bonds. In other cases, municipalities attempted to meet current and future
funding needs by issuing new debt.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and institutional investor activity slowed as holders of municipal bonds saw
little reason to sell bonds purchased at higher yield levels and reinvest at
lower yields. However, the period was marked by rising activity among non-
traditional investors such as hedge funds and insurance companies seeking to
take advantage of the attractiveness of municipal bonds relative to taxable
securities. Additionally, investors' search for yield led to significant
outperformance by lower-rated bonds with greater credit risk. Sectors such as
health care, with a preponderance of lower-rated issues, performed particularly
well.

PERFORMANCE ANALYSIS

The fund returned 2.84 percent for the six months ended March 31, 2004 (Class A
shares, unadjusted for sales charge), underperforming its benchmark, the Lehman
Brothers Municipal Bond Index. (See table below.) Our analysis of the economy
and interest rates indicated that the next major movement in rates was likely to
be upward, which we believed warranted a more defensive positioning. As a
result, we chose to emphasize securities that provided sufficient return
potential and were most likely to hold up well in a rising interest-rate
environment. This approach led us to de-emphasize bonds from the long end of the
curve given their high sensitivity to interest rates and low coupons; instead,
we focused on securities with premium coupons from the intermediate segment of
the market (15 to 22 years) in the belief that these bonds offered the most
attractive risk/reward profile. While we maintained this strategy through the
end of the period, investors seemed to prefer bonds with longer maturities, and
our approach limited the fund's ability to participate in their gains. We also
kept the fund's overall duration (a measure of interest-rate sensitivity) below
that of the benchmark, with a particular underweight in the 5- to 10-year
maturity range. We expect this area of the yield curve to underperform if the
Fed begins to raise rates again.

While we focused our purchases on intermediate bonds, we also took advantage of
short-term relative-value opportunities on the long end of the market. We
focused such trading in liquid, high-quality bonds in an effort to maximize
liquidity. Our high-quality bias was reflected in the portfolio as a whole,
which ended the period with 78.7 percent of its assets invested in securities
rated AA or higher.

We also maintained the portfolio's diversification over the reporting period.
The fund's holdings were spread across a broad spectrum of municipal-bond market
sectors in order to limit the risk of over-concentration in any one segment. At
the end of the period, the portfolio's largest sector weightings were
transportation at 14.7 percent, followed by general purpose at 12.8 percent and
public education at 12.6 percent.

We will continue to scour state and local markets across the country for
attractive investment opportunities.

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

(g) Payment-in-kind security.

(h) 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 Trust 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.

(a) Based on average shares outstanding.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, 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 deductions of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

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

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective
November 30, 2003, the Fund's investment adviser, Van Kampen Investment Advisory
Corp. merged into its affiliate, Van Kampen Asset Management (the "Adviser").

    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.
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, 2004, 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
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 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.

                                                                              23


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At September 30, 2003, the Fund had an accumulated capital loss
carryforward for tax purposes of $28,396,676 which will expire between September
30, 2008 and September 30, 2010.

    At March 31, 2004, the cost and related gross unrealized appreciation and

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund is an
affiliated person.

    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, 2004, the Fund recognized expenses of approximately $53,400 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, 2004, the Fund recognized expenses of approximately $182,800 representing
transfer agency fees paid to VKIS. Transfer agency fees are determined through
negotiations with the Fund's Board of Trustees.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and, to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of approximately $156,700
are included in "Other" assets on the Statements of Assets and Liabilities at
March 31, 2004. 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.

                                                                              25

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.

                                                                              27


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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 future contract. In this instance, the recognition of gain
or loss is postponed until the disposal of the security underlying the future
contract.

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

FUTURES CONTRACT 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, 2004,
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

 28


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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 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 $2,928,300 and $182,800
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in these fees for the six months ended March 31, 2004, are payments
retained by Van Kampen of approximately $35,400 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $234,800.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid excessive commissions to Morgan Stanley DW Inc. in connection with the
sales of the funds. The complaint seeks, among other things, the removal of the
current Trustees of the Van Kampen funds, rescission of the management contracts
for the Van Kampen funds, disgorgement of profits by Morgan Stanley and monetary
damages. This complaint will be coordinated with the consolidated complaint.

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.

                                                                              29

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Intermediate Term Municipal Income Fund performed during the semiannual
       period. The portfolio management team will provide an overview of the
       market conditions and discuss some of the factors that affected
       investment performance during the reporting period. In addition, this
       report includes the fund's financial statements and a list of fund
       investments as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

Past performance is no guarantee of future results and current performance may
be lower or higher than the figures shown. For more up-to-date information,
including 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.

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 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 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 is unmanaged and does not include

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2004

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

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust with Gross
Domestic Product growth topping 4% in both quarters. While this strength in
output has historically triggered fears of rising interest rates, yields
remained persistently low across the municipal curve. These low yields were
partly the result of the continued low levels of observed inflation in the U.S.
economy. Unfortunately, they also reflected continuing weakness in the job
market, which remained soft throughout the period. The soft job numbers, coupled
with persistently low inflation, led the Federal Open Market Committee (the Fed)
to maintain its accommodative stance throughout the period.

In keeping with the general trend for calendar 2003, the six months under review
saw high levels of issuance as municipalities sought to take advantage of
historically low interest rates. Many cities and states moved to reduce
expenditures by refinancing existing debt and replacing it with lower-yielding
bonds. In other cases, municipalities attempted to meet current and future
funding needs by issuing new debt.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and institutional investor activity slowed as holders of municipal bonds saw
little reason to sell bonds purchased at higher yield levels and reinvest at
lower yields. However, the period was marked by rising activity among non-
traditional investors such as hedge funds and insurance companies seeking to
take advantage of the attractiveness of municipal bonds relative to taxable
securities. Additionally, investors' search for yield led to significant
outperformance by lower-rated bonds with greater credit risk. Sectors such as
health care, with a preponderance of lower-rated issues, performed particularly
well.

PERFORMANCE ANALYSIS

The fund returned 2.35 percent for the six months ended March 31, 2004 (Class A
shares, unadjusted for sales charge), underperforming its benchmark, the Lehman
Brothers Municipal Bond Index. (See table below.) The period saw a flattening of
the yield curve, as short rates rose slightly and long rates declined. As a
result, bonds in the longest segment of the yield curve performed most strongly.
The fund's investment strategy is focused on the more conservative,
intermediate-maturity portion of the yield curve, limiting the fund's ability to
participate in this trend. This was the key driver of the fund's
underperformance relative to its benchmark index, which is broader and includes
a significant weighting of more-volatile, long-maturity bonds.

The most significant change in the fund's portfolio was in its aggregate credit
quality. With interest rates at such low levels, we focused our purchases on
well-researched securities in the middle tiers of the investment-grade market
that our analysis indicated offered the most attractive return potential. As a
result of this activity, the fund's holdings of securities rated A and AA
climbed by 10 percent, while its holdings of AAA rated bonds declined.

Our interest-rate strategy during the period was driven by our assessment of the
economy and interest rates. With yields at such low levels, we believed that the
next movement in interest rates was likely to be upward. This led us to position
the portfolio defensively by purchasing securities with attractive total-return
potential that are likely to perform well in the event of rising interest rates.
Many of these securities were intermediate bonds with premium coupons and
attractive structural characteristics. At the same time, we de-emphasized the
five- to 10-year portion of the curve, which our analysis showed was likely to
suffer most in a rising interest-rate environment.

We also maintained the portfolio's diversification over the reporting period.
The fund's holdings were spread across the full spectrum of municipal-bond
market sectors in order to limit the risk of over-concentration in any one
segment. At the end of the period, the portfolio's largest sector weightings
were general purpose at 16.2 percent, followed by public building at 14.0
percent and public education at 13.1 percent.

We will continue to scour state and local markets across the country for
attractive investment opportunities.

distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future

**  Non-Annualized

(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 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.

    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 by .01%. Per share, ratios and

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective November 30,
2003, the Fund's investment adviser, Van Kampen Investment Advisory Corp. merged
into its affiliate, Van Kampen Asset Management.

    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 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, 2004, 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
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 the Internal Revenue Code applicable to regulated investment companies and to
distribute

                                                                              19

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are

tax purposes.

Undistributed long-term capital gain........................  $167,866

F. EXPENSE REDUCTIONS During the six months ended March 31, 2004, the Fund's
custody fee was reduced by $260 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, 2004, the Adviser waived $59,396 of its
investment advisory fee. This represents .10% of its average net assets for the
period. This waiver is voluntary in nature and can be discontinued at the
Adviser's discretion.

    For the six months ended March 31, 2004, the Fund recognized expenses of
approximately $3,000 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is an affiliated person.

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

    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, 2004, 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, 2004, the Fund recognized expenses of approximately $24,900,
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund, and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of approximately $101,800
are included in "Other" assets on the Statement of Assets and Liabilities at
March 31, 2004. 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.

                                                                              21

    For the six months ended March 31, 2004, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $8,800 and CDSC on redeemed shares of approximately $24,600. 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 $43,410,867 and $41,983,888 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,

                                                                              23


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

except when taking delivery of a security underlying a futures contract. In
these instances, the recognition of gain or loss is postponed until the disposal
of the security underlying the futures contract.

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in exchange traded futures contracts on U.S. Treasury Bonds
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, 2004,
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.

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

    Annual fees under the Plans of up to .25% of Class A average daily net
assets and 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 $1,296,800, and
$34,200, for Class B and Class C shares, respectively. These amounts may be
recovered from future payments under the distribution plan or CDSC. To the
extent the unreimbursed receivable has been fully recovered, any excess 12b-1
fees will be refunded to the Fund on a quarterly basis.

    Included in these fees for the six months ended March 31, 2004, are payments
retained by Van Kampen of approximately $149,200, and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $11,600.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid excessive commissions to Morgan Stanley DW Inc. in connection with the
sales of the funds. The complaint seeks, among other things, the removal of the
current Trustees of the Van Kampen funds, rescission of the management contracts
for the Van Kampen funds, disgorgement of profits by Morgan Stanley and monetary
damages. This complaint will be coordinated with the consolidated complaint.

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.

                                                                              25

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen New
       York Tax Free Income Fund performed during the semiannual period. The
       portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the fund's financial statements and a list of fund investments
       as of March 31, 2004.

       This material must be preceded or accompanied by a prospectus for the
       fund being offered.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that a mutual fund will achieve its
       investment objective. Funds are subject to market risk, which is the
       possibility that the market values of securities owned by the fund will
       decline and that the value of fund shares may therefore be less than what
       you paid for them. Accordingly, you can lose money investing in this
       fund. Please see the prospectus for more complete information on
       investment risks.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

Past performance is no guarantee of future results and current performance may
be lower or higher than the figures shown. For more up-to-date information,
including 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.

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 1.00 percent for Class B and C shares. The since
inception return for Class B shares reflect its conversion into Class A shares
seven 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 is unmanaged and does not include
any sales charges or fees. Such costs would lower performance. It is not
possible to invest directly in an index.

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust with Gross
Domestic Product growth topping 4% in both quarters. While this strength in
output has historically triggered fears of rising interest rates, yields
remained stubbornly low across the municipal yield curve. These low yields were
partly the result of the continued low levels of observed inflation in the U.S.
economy. Unfortunately, they also reflected continuing weakness in the job
market, which remained soft throughout the period. The soft job numbers, coupled
with persistently low inflation, led the Federal Open Market Committee (the Fed)
to maintain its accommodative stance throughout the period.

In keeping with the general trend for calendar 2003, the six months under review
saw record levels of issuance as municipalities sought to take advantage of
historically low interest rates. Many cities and states moved to reduce
expenditures by refinancing existing debt and replacing it with lower-yielding
bonds. In other cases, municipalities attempted to meet current and future
funding needs by issuing new debt.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and institutional investor activity slowed as holders of municipal bonds saw
little reason to sell bonds purchased at higher yield levels and reinvest at
historically low yields. However, the period was marked by rising activity among
non-traditional investors, such as hedge funds and insurance companies seeking
to take advantage of the attractiveness of municipal bonds relative to taxable
securities. Additionally, investors' search for yield led to significant
outperformance by lower-rated bonds with greater credit risk. Sectors such as
health care, with a preponderance of lower-rated issues, performed particularly
well.

The New York economy continued to struggle with fiscal problems during the
period, and the executive and legislative branches of the state government
remained locked in their perennial budget battle. Signs of economic improvement
in the rest of the country, however, did bode particularly well for New York,
since the state's tax revenues are in large part driven by revenues from the
financial sector. The state continued to be among the country's largest

municipal-bond issuers as local- and state-level projects sought funding for
their ongoing operations.

PERFORMANCE ANALYSIS

The fund returned 3.02 percent for the six months ended March 31, 2004 (Class A
shares, unadjusted for sales charges), modestly underperforming its benchmark,
the Lehman Brothers Municipal Bond Index. (See table below.) Our analysis of the
economy and interest rates indicated that the next major movement in rates was
likely to be upward, which to our thinking warranted a more defensive
positioning. As a result, we chose to emphasize securities that provided
sufficient return potential and were most likely to hold up well in a rising
interest-rate environment. We de-emphasized low-coupon bonds from the long end
of the yield curve given their high sensitivity to interest rates, focusing
instead on securities with premium coupons from the 15- to 22-year segment of
the market in the belief that these bonds offered the most attractive
risk/reward profile. We also kept the fund's overall duration (a measure of
interest-rate sensitivity) below that of the benchmark. Unfortunately, the
longer segment of the curve outperformed during the period, and our defensive
stance hampered performance slightly.

We funded our purchases of intermediate bonds with the proceeds of sales from
elsewhere in the portfolio. These sales included several of the fund's longer-
dated positions as well as some of its income-oriented positions that had met
their performance targets during the period. The fund also benefited from
pre-refundings of several securities, which helped support the portfolio's net
asset value (NAV). We generally limited our purchases to liquid, high-quality
bonds. Our high-quality bias was reflected in the portfolio as a whole, which
ended the period with more than 80 percent of its assets invested in securities
rated AA or higher.

We also maintained the portfolio's diversification over the reporting period.
The fund's holdings were spread across the full spectrum of municipal-bond
market sectors in order to limit the risk of over-concentration in any one
segment. At the end of the period, the portfolio's largest sector weightings
were general

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.
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.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and an

purpose at approximate 24 percent, followed by higher education at approximate
19 percent and health care at approximate 9 percent.

We anticipate that rates may eventually begin to move upward. That being said,
we believe the fund is positioned to continue to provide investors with
attractive income across an array of possible market environments. We will
continue to actively explore the New York market for attractive investment
opportunities.

(a) All or a portion of this security has been physically segregated in
    connection with open futures contracts.

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

(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 Trust 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.

(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 one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include Rule 12b-1 fees of up to .25% and do not reflect the deduction of
    taxes that a shareholder would pay on Fund distributions or the redemption
    of Fund shares.

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (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. Effective November 30, 2003, the
Fund's investment adviser, Van Kampen Investment advisory Corp. merged into its
affiliate, Van Kampen Asset Management.

    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.
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, 2004, 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
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 the Internal Revenue Code applicable to regulated investment companies and to
distribute

                                                                              17

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, 2003, the Fund had an accumulated capital loss
carryforward for tax purposes of $733,829 which will expire on September 30,
2009.

    At March 31, 2004, 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,
2003 was as follows:

<Table>

                                                                $6,501

    As of September 30, 2003, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                             
Undistributed ordinary income...............................    $11,191
</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.

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:

    For the six months ended March 31, 2004, the Adviser waived approximately
$215,000 of its advisory fees. This represents .35% 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, 2004, the Fund recognized expenses of
approximately $3,100, representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is an affiliated person.

    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, 2004, the Fund recognized expenses of approximately $19,900 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, 2004, 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
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 $55,170 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2004.
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.

                                                                              19

A derivative financial instrument in very general terms refers to a security

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 these instances, the recognition of gain or
loss is postponed until the disposal of the security underlying the futures
contract.

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in exchange traded futures contracts on U.S. Treasury 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, 2004,
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

 22


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2004 (UNAUDITED) continued

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 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 $725,600 and $15,300
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 these fees for the six months ended March 31, 2004, are payments
retained by Van Kampen of approximately $193,400 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $17,900.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, certain officers of such
affiliates 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 the
named 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 recommend 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 efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, rescissionary damages,
fees and costs.

    The Adviser, certain affiliates of the Adviser and certain investment
companies advised by the Adviser or its affiliates are also named as defendants
in a derivative suit which additionally names as defendants certain individual
Trustees of the Van Kampen funds; the funds, including the Fund, are also named
as nominal defendants. The complaint in the derivative action alleges that
defendants gave a proprietary sales force economic incentives to promote the
sale of proprietary mutual funds and that they improperly failed to disclose
these economic incentives. The complaint also alleges that the Van Kampen funds
paid excessive commissions to Morgan Stanley DW Inc. in connection with the
sales of the funds. The complaint seeks, among other things, the removal of the
current Trustees of the Van Kampen funds, rescission of the management contracts
for the Van Kampen funds, disgorgement of profits by Morgan Stanley and monetary
damages. This complaint will be coordinated with the consolidated complaint.

                                                                              23

    The defendants intend to move to dismiss these actions and otherwise
vigorously to defend them. While the Fund believes that it has 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.
