INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year six), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect their conversion into Class A shares seven years after purchase. The since inception returns for Class C shares reflect their conversion into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding nonincome items as prescribed by the SEC. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. Index data source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005 Van Kampen Insured Tax Free Income Fund is managed by the Adviser's Municipal Fixed Income team.(1) Members of the team include James F. Willison, Managing Director of the Adviser; Joseph R. Arcieri, Executive Director of the Adviser; and Joseph A. Piraro, Vice President of the Adviser. MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (the difference between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market in total posted positive returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. (1)Team members may change at any time without notice. 2 PERFORMANCE ANALYSIS The fund returned 0.84 percent for the six months ended March 31, 2005 (Class A shares, unadjusted for sales charge). In comparison, the fund's benchmark index, the Lehman Brothers Municipal Bond Index, returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - -------------------------------------------------------------- LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 0.84% 0.46% 0.46% 1.21% - -------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITIONS. One of our primary strategies in managing the fund was to take advantage of compelling opportunities in the 25- to 30-year segment of the market. We focused here on purchasing securities with premium (that is, above-market) coupons and moderate interest rate sensitivity. Our purchases of these securities were funded by the proceeds of sales of several shorter-maturity positions, many of which had been refunded during the period. This was part of our ongoing strategy of positioning the fund for an environment of rising short-term interest rates by limiting the fund's exposure to that segment of the market. In terms of purchases, we continued to favor the essential services segments of the market, such as education and transportation. In turn, we avoided the housing sector out of concerns about those bonds' structural characteristics. We also avoided zero coupon bonds. The fund remained well diversified geographically, with no one state or region dominating the portfolio. Many of our purchases were from states with either high taxes, and thus strong ongoing demand for the bonds, or a lack of dual tax-exempt status, such as Illinois. Because the fund focuses on bonds that offer the credit enhancement of insurance, the entire portfolio was rated AAA at the close of the period. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 3/31/05 Illinois 15.0% Texas 12.9 California 10.3 Washington 8.8 Florida 6.8 Colorado 4.4 Pennsylvania 4.2 Indiana 3.3 Louisiana 2.8 Oklahoma 2.8 Georgia 2.6 Alabama 2.4 New Jersey 2.2 Michigan 2.1 Arizona 2.0 North Carolina 1.7 Nevada 1.6 New York 1.5 South Dakota 1.3 District of Columbia 1.1 Wisconsin 1.1 North Dakota 0.9 South Carolina 0.8 Arkansas 0.8 Ohio 0.5 Missouri 0.5 Massachusetts 0.5 Oregon 0.4 Alaska 0.4 West Virginia 0.4 Utah 0.3 Puerto Rico 0.3 New Hampshire 0.2 Iowa 0.2 Nebraska 0.2 Mississippi 0.1 Virginia 0.1 ----- Total Long-Term Investments 97.5% Short-Term Investments 4.4 ----- Total Investments 101.9 Liabilities in Excess of Other Assets -1.9 ----- Net Assets 100.0% </Table> <Table> <Caption> CREDIT QUALITY AS OF MARCH 31, 2005 AAA/Aaa 98.7% Not Rated 1.3 </Table> Based upon the highest quality ratings as issued by Standard & Poor's or Moody's. 4 <Table> <Caption> TOP FIVE SECTORS AS OF MARCH 31, 2005 Public Education 17.0% Public Building 11.3 Wholesale Electric 11.1 Airport 10.9 General Purpose 9.8 </Table> Subject to change daily.

You can request multiple copies of these documents by either calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD The fund's policies and procedures with respect to the voting of proxies relating to the fund's portfolio securities and information on how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is available without charge, upon request, by visiting our Web site at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs : (1) transaction costs, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/01/04 - 3/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD* ------------------------------------------------- 10/1/04 3/31/05 10/1/04-3/31/05 Class A Actual..................................... $1,000.00 $1,008.44 $4.41 Hypothetical............................... 1,000.00 1,020.53 4.43 (5% annual return before expenses) Class B Actual..................................... 1,000.00 1,004.56 8.15 Hypothetical............................... 1,000.00 1,016.83 8.20 (5% annual return before expenses) Class C Actual..................................... 1,000.00 1,004.56 8.15 Hypothetical............................... 1,000.00 1,016.83 8.20 (5% annual return before expenses) </Table> * Expenses are equal to the Fund's annualized expense ratio of 0.88%, 1.63%, and 1.63% for Class A, B, and C Shares, respectively, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

The effect of this change for the year ended September 30, 2002 was to increase net investment income per share by less than $.01, decrease net realized and unrealized gains and losses per share by less than $.01, and increase the ratio of net investment income to average net assets from 4.27% to 4.30%. Per share, ratios and supplemental data for the periods prior to September 30, 2002 have not been restated to reflect this change in presentation. (b) Assumes reinvestment of all distributions for the period and does not include payment of the maximum sales charge of 4.75% or contingent deferred sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be imposed on certain redemptions made within eighteen months of purchases. With respect to shares purchased prior to December 1, 2004, a CDSC of 1% may be imposed on certain redemptions made within one year of purchase.

See Notes to Financial Statements 31 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) 1. SIGNIFICANT ACCOUNTING POLICIES Van Kampen Insured Tax Free Income Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a diversified open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide investors a high level of current income exempt from federal income taxes, with liquidity and safety of principal, primarily through investment in a diversified portfolio of insured municipal securities. The Fund commenced investment operations on December 14, 1984. The distribution of the Fund's Class B and Class C Shares commenced on May 3, 1993 and August 13, 1993, respectively. The Fund registered Class I Shares on August 31, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At March 31, 2005, the Fund had $33,336,090 of when-issued and delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies 32 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. At March 31, 2005, the cost and related gross unrealized appreciation and depreciation were as follows: <Table> Cost of investments for tax purposes........................ $1,153,299,884 ============== Gross tax unrealized appreciation........................... $ 59,622,580 Gross tax unrealized depreciation........................... (3,257,755) -------------- Net tax unrealized appreciation on investments.............. $ 56,364,825 ============== </Table> E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short-term capital gains and a portion of futures gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended September 30, 2004 was as follows: <Table> Distributions paid from: Ordinary Income........................................... $ 1,429,233 Long-term capital gain.................................... 14,007,249 ----------- $15,436,482 ----------- </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $1,832,228 Undistributed long-term capital gain........................ 9,263,391 </Table> F. INSURANCE EXPENSES The Fund typically invests in insured bonds. Any portfolio securities not specifically covered by a primary insurance policy are insured secondarily through the Fund's portfolio insurance policy. Insurance premiums are based on the daily balances of uninsured bonds in the portfolio of investments and are charged to expense on an accrual basis. The insurance policy guarantees the timely payment of principal and interest on the securities in the Fund's portfolio. G. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's custody fee was reduced by $11,729 as a result of credits earned on cash balances. 33 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... 0.525 Next $500 million........................................... 0.500 Next $500 million........................................... 0.475 Over $1.5 billion........................................... 0.450 </Table> For the six months ended March 31, 2005, the Fund recognized expenses of approximately $28,300 representing legal expenses provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund. Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $51,900 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses, respectively, in the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $296,400, representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of $229,011 are included in "Other" assets on the Statement of Assets and Liabilities at March 31, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligations and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 34 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 3.

Class B Shares purchased before June 1, 1996, and any dividend reinvestment plan Class B Shares received on such shares, automatically convert to Class A Shares seven years after the end of the calendar month in which the shares were purchased. For the six months ended March 31, 2005 and the year ended September 30, 2004, 147,343 and 106,142 Class B Shares converted to Class A Shares, respectively, and are shown in the above tables as sales of Class A Shares and repurchases of Class B Shares. Class C Shares purchased before January 1, 1997, and any dividend reinvestment plan Class C Shares received on such shares, automatically convert to Class A Shares ten years after the end of the calendar month in which such shares were purchased. Class C Shares purchased on or after January 1, 1997 do not possess a conversion feature. For the six months ended March 31, 2005 and the year ended September 30, 2004, 30,727 and no Class C Shares converted to Class A Shares. Class B and Class C Shares are offered without a front end sales charge, but are subject to a contingent deferred sales charge (CDSC). The CDSC for Class B and Class C Shares will be imposed on most redemptions made within six years of the purchase for Class B and one year of the purchase for Class C as detailed in the following schedule. <Table> <Caption> CONTINGENT DEFERRED SALES CHARGE AS A PERCENTAGE OF DOLLAR AMOUNT SUBJECT TO CHARGE -------------------------- YEAR OF REDEMPTION CLASS B CLASS C First....................................................... 4.00% 1.00% Second...................................................... 3.75% None Third....................................................... 3.50% None Fourth...................................................... 2.50% None Fifth....................................................... 1.50% None Sixth....................................................... 1.00% None Seventh and Thereafter......................................

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 $293,546,145 and $303,661,724, 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 36 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued the portfolio's effective yield, maturity and duration. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Summarized below are the specific types of derivative financial instruments used by the Fund. A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in exchange traded futures contracts on U.S. Treasury Notes and typically closes the contract prior to the delivery date. Upon entering into futures contracts, the Fund maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts, for the six months ended March 31, 2005, were as follows: <Table> <Caption> CONTRACTS Outstanding at September 30, 2004........................... 1,435 Futures Opened.............................................. 5,162 Futures Closed.............................................. (4,223) ------ Outstanding at March 31, 2005............................... 2,374 ====== </Table> The futures contracts outstanding as of March 31, 2005, and the descriptions and unrealized appreciation/depreciation are a follows: <Table> <Caption> UNREALIZED CONTRACTS APPRECIATION SHORT CONTRACTS: US Treasury Notes 5-Year Futures, June 2005 (Current Notional Value of $107,094 per contract).................. 2,374 $1,750,192 </Table> B. INVERSE FLOATING RATE SECURITIES An Inverse Floating Rate security is one where the coupon is inversely indexed to a short-term floating interest rate multiplied by a specified factor. As the floating rate rises, the coupon is reduced. Conversely as the floating rate declines, the coupon is increased. The price of these securities may be more volatile than the price of a comparable fixed rate security. These instruments are typically used by the Fund to enhance the yield of the portfolio. 37 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 6. DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to .25% of Class A average daily net assets and up to 1.00% each of Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. The amount of distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was approximately $1,573,500 and $59,800 for Class B and Class C Shares, respectively. This amount may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended March 31, 2005, are payments retained by Van Kampen of approximately $362,300 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $45,300. 7. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with 38 VAN KAMPEN INSURED TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative compliant that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, that plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss each of these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 39 VAN KAMPEN INSURED TAX FREE INCOME FUND BOARD OF TRUSTEES AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.

Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year six), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares seven years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. Index data source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005 Van Kampen Strategic Municipal Income Fund is managed by the Adviser's Municipal Fixed Income team.(1) Members of the team include Wayne D. Godlin, Managing Director of the Adviser; and Dennis S. Pietrzak and James D. Phillips, Executive Directors of the Adviser. MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (the difference between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market in total posted positive returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. (1)Team members may change without notice at any time. 2 PERFORMANCE ANALYSIS The fund returned 3.98 percent for the six months ended March 31, 2005 (Class A shares, unadjusted for sales charge). In comparison, the fund's benchmark index, the Lehman Brothers Municipal Bond Index, returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - -------------------------------------------------------------- LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 3.98% 3.59% 3.56% 1.21% - -------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITIONS. The fund's relative outperformance was largely the result of its focus on higher-yielding municipal bonds. Despite ongoing increases to the federal funds target rate, yields on intermediate- and longer-maturity bonds remained relatively low for much of the period. As a result, investors hungry for yield income bid up the prices of higher-yielding securities over the period. This trend was a benefit to the fund, especially given its benchmark's lack of exposure to non-rated securities. During the first quarter of 2005, the fund also benefited from taking an initial limited position in tobacco bonds. We added these securities based on our evaluation of reduced litigation risk for the industry just prior to favorable developments in the federal courts. The sector appreciated early in 2005, and the portfolio gained as a result of its exposure. Not all of the fund's positions were so favorable. Based on our analysis of interest rates, the fund's duration (a measure of interest-rate exposure) was below that of its benchmark index over the period. While this stance supported returns in those weeks when rates rose, it was not uniformly helpful across the period. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> <Caption> RATING ALLOCATIONS AS OF 3/31/05 AAA/Aaa 10.8% AA/Aa 4.9 A/A 5.9 BBB/Baa 13.5 BB/Ba 3.2 B/B 5.1 Non-Rated 56.6 <Caption> TOP 5 SECTORS AS OF 3/31/05 Health Care 20.2% Continuing Care 18.1 Industrial Revenue 16.4 Tax District 14.7 General Purpose 5.5 <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 3/31/05 Florida 10.6% Texas 7.2 California 7.1 Illinois 6.9 Pennsylvania 6.3 New York 6.2 New Jersey 5.7 Missouri 4.8 Ohio 3.5 Massachusetts 3.1 Arizona 3.1 Minnesota 3.0 Colorado 2.8 Oklahoma 2.3 Georgia 2.2 Michigan 2.1 Maryland 1.9 Washington 1.7 Wisconsin 1.4 Tennessee 1.4 North Carolina 1.3 South Carolina 1.1 Oregon 1.1 Alabama 1.0 New Hampshire 1.0 Virginia 1.0 Puerto Rico 1.0 Indiana 1.0 Iowa 0.9 Nevada 0.9 South Dakota 0.9 Louisiana 0.8 Kansas 0.7 Hawaii 0.6 </Table> <Table> (continued on next page) </Table> 4 <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 3/31/05 (continued from previous page) New Mexico 0.6 Connecticut 0.6 District of Columbia 0.5 Rhode Island 0.5 Alaska 0.4 Maine 0.4 U.

You can request multiple copies of these documents by either calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD The fund's policies and procedures with respect to the voting of proxies relating to the fund's portfolio securities and information on how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is available without charge, upon request, by visiting our website at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and Class C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/1/04 - 3/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your cost would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD* -------------------------------------------------- 10/1/04 3/31/05 10/1/04-3/31/05 Class A Actual.................................... $1,000.00 $1,039.78 $4.27 Hypothetical.............................. 1,000.00 1,020.73 4.23 (5% annual return before expenses) Class B Actual.................................... 1,000.00 1,035.94 8.07 Hypothetical.............................. 1,000.00 1,017.03 8.00 (5% annual return before expenses) Class C Actual.................................... 1,000.00 1,035.64 8.07 Hypothetical.............................. 1,000.00 1,017.03 8.00 (5% annual return before expenses) </Table> * Expenses are equal to the Fund's annualized expense ratio of 0.84%, 1.60%, and 1.59% for Class A, B, and C Shares, respectively, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

The price of these securities may be more volatile than the price of a comparable fixed rate security. These instruments are typically used by the Fund to enhance the yield of the portfolio. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly. (d) The Fund owns 100% of the bond issuance. (e) Interest is accruing at less than the stated coupon. (f) Non-income producing security. (g) This borrower has filed for protection in federal bankruptcy court.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Strategic Municipal Income Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a diversified, open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide investors a high level of current income exempt from federal income tax primarily through investment in a diversified portfolio of medium- and lower-grade municipal securities. The Fund commenced investment operations on June 28, 1985. The distribution of the Fund's Class B and Class C shares commenced on April 30, 1993 and August 13, 1993, respectively. The Fund registered Class I Shares on December 30, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. Legal expenditures that are expected to result in the restructuring of or a plan of reorganization for an investment are recorded as realized losses. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At March 31, 2005, the Fund had $30,480,257 of when-issued or delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. 43 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset these losses against any future realized capital gains. At September 30, 2004, the Fund had an accumulated capital loss carryforward for tax purposes of $72,989,958, which will expire according to the following schedule. <Table> <Caption> AMOUNT EXPIRATION $ 9,854,061.................................................

DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended September 30, 2004 is as follows: <Table> <Caption> 2004 Distributions paid from: Ordinary income........................................... $115,296 Long-term capital gain.................................... -0- -------- $115,296 ======== </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $1,403 </Table> 44 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued Net realized gains or losses may differ for financial and tax reporting purposes primarily as a result of the deferral of losses related to wash sale transactions and the capitalization of reorganization and restructuring costs, and losses recognized for tax purposes but not for book purposes. F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's custody fee was reduced by $20,072 as a result of credits earned on cash balances. 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... .50% Over $500 million........................................... .45% </Table> For the six months ended March 31, 2005, the Fund recognized expenses of approximately $6,200 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund. Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $44,600 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses in the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent of the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $222,300 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of $138,024 are included in "Other" assets on the Statement of Assets and Liabilities at March 31, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 45 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 3.

INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $488,841,428 and $234,092,284, 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. 47 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued The Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio, to manage the portfolio's effective yield, maturity and duration, or generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risks may arise as a result of the potential inability of the counter parties to meet the terms of their contracts. During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in exchange traded futures contracts on U.S. Treasury Securities and typically closes the contract prior to the delivery date. These contracts are generally used to manage the Fund's effective maturity and duration. Upon entering into futures contracts, the Fund maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities.

DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to 0.25% of Class A average daily net assets and up to 1.00% each for Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. The amount of distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was approximately $2,710,700 and $325,900 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended March 31, 2005, are payments retained by Van Kampen of approximately $816,800 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $38,100. 7. LEGAL MATTERS. The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with 49 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative complaint that alleges that the Adviser permitted or recklessly disregarded market timing and later trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, the plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss each of these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 50 VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.

INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 3.25 percent for Class A shares, a contingent deferred sales charge of 3.00 percent for Class B shares (in year one and declining to zero after year four), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares six years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index.

Pietrzak and John R. Reynoldson, Executive Directors of the Adviser; and Joseph A. Piraro, Vice President of the Adviser. MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (the difference between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market in total posted positive returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. From a credit perspective, the state of California has made some positive strides. The California government's measures to stem current and projected budget deficits have been met with broad approval by investors. This in turn has resulted in improved demand for California bonds and a general rise in bond prices. During the period, the state maintained its position as the leading issuer of new municipal debt. More than half of the new issuance which came to market was protected by credit insurance, which was helpful for us as we attempted to put cash to work.

In comparison, the fund's benchmark index, the Lehman Brothers Municipal Bond Index, returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - ------------------------------------------------------------------------------ LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 1.08% 1.08% 0.71% 1.21% - ------------------------------------------------------------------------------ </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITIONS. The fund's performance relative to its benchmark was in large part the result of its positioning along the yield curve. One of our primary strategies in managing the fund was to take advantage of compelling opportunities in the 25- to 30-year segment of the market. We focused here on purchasing securities with premium (that is, above-market) coupons and moderate interest rate sensitivity. While we believe these securities offer strong total return potential, they did boost the fund's exposure during the period to a segment of the California market which underperformed relative to the broader, national benchmark. Our purchases of these securities were funded by the proceeds of sales of several shorter-maturity positions, many of which had been refunded during the period. This was part of our ongoing strategy of positioning the fund for an environment of rising short-term interest rates by limiting the fund's exposure to that segment of the market. In terms of purchases, we continued to favor the essential services segments of the market, such as education and transportation. In turn, we avoided the housing sector out of concerns about those bonds' structural characteristics. We also avoided zero coupon bonds. This approach resulted in a portfolio that remained well diversified across the major segments of the California municipal bond market. Tax districts, public education, higher education, public building and general purpose represented the portfolio's top exposures. Because the fund focuses on bonds that offer the credit enhancement of insurance, the entire portfolio was rated AAA at the close of the period. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> RATINGS ALLOCATIONS AS OF 3/31/05 TOP 5 SECTORS AS OF 3/31/05 AAA/Aaa 100% Tax District 21.8% Public Education 18.9 Higher Education 13.6 Public Building 13.4 General Purpose 12.3 </Table> Subject to change daily.

This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov 6 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction cost, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/01/04 - 03/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, and $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

(b) An Inverse Floating Rate security is one where the coupon is inversely indexed to a short-term floating interest rate multiplied by a specific factor. As the floating rate rises, the coupon is reduced. Conversely, as the floating rate declines, the coupon is increased. The price of these securities may be more volatile than the price of a comparable fixed rate security. These instruments are typically used by the Fund to enhance the yield of the portfolio. All of the Trust's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/depreciation.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen California Insured Tax Free Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a diversified, open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide only California investors with a high level of current income exempt from federal and California income taxes, with liquidity and safety of principal, primarily through investment in a diversified portfolio of insured California municipal securities. The Fund commenced investment operations on December 13, 1985. The distribution of the Fund's Class B Shares and Class C Shares commenced on April 30, 1993 and August 13, 1993, respectively. The Fund registered Class I Shares on September 1, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At March 31, 2005, the Fund had $6,079,743 of when-issued and delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies 21 VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. At March 31, 2005, the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $226,456,917 ============ Gross tax unrealized appreciation........................... $ 13,036,211 Gross tax unrealized depreciation........................... (173,971) ------------ Net tax unrealized appreciation on investments.............. $ 12,862,240 ============ </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, 2004 was as follows: <Table> Distributions paid from: Ordinary income........................................... $6,710 Long-term capital gain.................................... -0- ------ $6,710 ====== </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $ 543 Undistributed long-term capital gain........................ 1,481,141 </Table> F. INSURANCE EXPENSE The Fund typically invests in insured bonds. Any portfolio securities not specifically covered by a primary insurance policy are insured secondarily through the Fund's portfolio insurance policy. Insurance premiums are based on the daily balances of uninsured bonds in the portfolio of investments and are charged to expense on an accrual basis. The insurance policy guarantees the timely payment of principal and interest on the securities in the Fund's portfolio. G. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's custody fee was reduced by $1,583 as a result of credits earned on cash balances. 22 VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 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 $100 million.......................................... 0.500 Next $150 million........................................... 0.450 Next $250 million........................................... 0.425 Over $500 million........................................... 0.400 </Table> For the six months ended March 31, 2005, the Fund recognized expenses of approximately $8,500 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund. Under separate Accounting Services and Legal Services Agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $26,300 representing Van Kampen Investment Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses, respectively, in the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $54,300 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of $112,160 are included in "Other" assets on the Statement of Assets and Liabilities at March 31, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 23 VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 3.

Sales charges do not represent expenses of the Fund. 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $20,468,005 and $16,831,226, respectively. 5. DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to .25% of Class A average daily net assets and up to 1.00% each of Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. At March 31, 2005, there were no distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") for Class B and Class C Shares. Any unreimbursed receivables may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended March 31, 2005 are payments retained by Van Kampen of approximately $19,400 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $23,100. 6. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. This consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of the 26 VAN KAMPEN CALIFORNIA INSURED TAX FEE FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative compliant that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, that plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss each of these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 7. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 27 VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND BOARD OF TRUSTEES AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.

INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year six), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares six years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. Index data source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005 Van Kampen Municipal Income Fund is managed by the Adviser's Municipal Fixed Income team.(1) Current members of the team include James F. Willison, Managing Director of the Adviser; Joseph R. Arcieri, Executive Director of the Adviser; and Timothy D. Haney, Vice President of the Adviser. MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (the difference between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market in total posted positive returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. (1)Team members may change without notice at any time. 2 PERFORMANCE ANALYSIS The fund returned 0.63 percent for the six months ended March 31, 2005 (Class A shares, unadjusted for sales charge). In comparison, the fund's benchmark index, Lehman Brothers Municipal Bond Index returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - -------------------------------------------------------------- LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 0.63% 0.26% 0.27% 1.21% - -------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITION. The fund's underperformance relative to its benchmark was largely the result of its exposure to bonds with maturities in the five- to 10-year range. These securities were especially hard hit by rising interest rates during the period, and the fund's above-market exposure meant that it suffered more than did the broader market benchmark from their poor performance. We trimmed many of these holdings as part of an ongoing strategy to position the fund for continued increases in short-term interest rates. This strategy also included adding selectively to the fund's holdings of bonds with longer maturities but moderate interest rate characteristics. Finally, we kept the fund's duration (a measure of overall interest-rate sensitivity) below that of its benchmark. We continued to focus on relative-value trading between liquid, high-quality securities to capture relative value opportunities identified by our analysts. The fund's overall credit exposure remained tilted toward higher-quality securities, with more than 81 percent of its exposure at the end of the period in bonds rated AA or better. That said, the portfolio also had approximately 14 percent of its exposure in bonds rated BBB or lower. These positions benefited from the ongoing outperformance by lower-rated bonds, and were beneficial to the fund's returns. The fund's portfolio remained well diversified across the major sectors of the municipal bond market, with its top three sectors at the end of the period being general purpose, transportation and wholesale electric. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> <Caption> RATINGS ALLOCATIONS AS OF 3/31/05 AAA 68.5% AA 13.0 A 5.0 BBB 4.8 BB 0.9 B 0.3 NR 7.5 <Caption> TOP 5 SECTORS AS OF 3/31/05 General Purpose 17.6% Transportation 11.7 Wholesale Electric 10.4 Public Education 10.3 Water & Sewer 9.1 <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 3/31/05 New York 15.6% California 12.8 Texas 8.4 Illinois 8.1 New Jersey 7.9 Colorado 6.0 Florida 5.9 Michigan 3.9 Arizona 3.4 Massachusetts 3.3 Oregon 2.7 Washington 2.2 Utah 2.0 Connecticut 1.9 Missouri 1.8 North Carolina 1.4 Indiana 1.4 District of Columbia 1.3 Kansas 1.1 Tennessee 1.1 Georgia 1.1 Pennsylvania 1.1 West Virginia 0.9 New Hampshire 0.8 Alabama 0.6 Rhode Island 0.5 Iowa 0.5 Oklahoma 0.4 South Dakota 0.4 Arkansas 0.3 Louisiana 0.2 </Table> <Table> (continued on next page) </Table> 4 <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 3/31/05 (continued from previous page) Vermont 0.2 South Carolina 0.1 ----- Total Investments 99.3% Other Assets in Excess of Liabilities 0.7 ----- Total Net Assets 100.0% </Table> Subject to change daily.

The fund's prospectuses and shareholder reports (including annual privacy notices) will be delivered to you in this manner indefinitely unless you instruct us otherwise. You can request multiple copies of these documents by either calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD The fund's policies and procedures with respect to the voting of proxies relating to the fund's portfolio securities and information on how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is available without charge, upon request, by visiting our Web site at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/1/04 - 3/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Municipal Income Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a diversified open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide a high level of current income exempt from federal income tax, consistent with preservation of capital. The Fund commenced investment operations on August 1, 1990. The distribution of the Fund's Class B and Class C shares commenced on August 24, 1992 and August 13, 1993, respectively. The Fund registered Class I Shares on September 1, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Future contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. Legal expenditures that are expected to result in the restructuring of or a plan of reorganization for an investment are recorded as realized losses. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At March 31, 2005, the Fund had no when-issued and delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies 26 VAN KAMPEN MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset these losses against any future realized capital gains. At September 30, 2004, the Fund had an accumulated capital loss carryforward for tax purposes of $27,985,150 which will expire according to the following schedule. <Table> <Caption> AMOUNT EXPIRATION $11,008,462.................................................

Distributions from net realized gains for book purposes may include short-term capital gains, which are included in ordinary income for tax purposes. The tax character of distributions paid during the year ended September 30, 2004 was as follows: <Table> Distribution paid from: Ordinary Income........................................... $291,037 Long-term capital gain.................................... -0- -------- $291,037 ======== </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $117,235 </Table> F.

Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $37,200 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses, respectively, on the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $166,700 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and, to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of $161,615 are included in "Other" assets on the Statements of Assets and Liabilities at March 31, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 28 VAN KAMPEN MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 3.

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. 30 VAN KAMPEN MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued The Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio, to manage the portfolio's effective yield, maturity and duration, or generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risks may arise as a result of the potential inability of the counter parties to meet the terms of their contracts. During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in futures on U.S. Treasury Notes. Upon entering into futures contracts, the Fund maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended March 31, 2005, were as follows: <Table> <Caption> CONTRACTS Outstanding at September 30, 2004........................... 575 Futures Opened.............................................. 540 Futures Closed..............................................

DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively, the "Plans"). The Plans govern payments for: the 31 VAN KAMPEN MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and the maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to 0.25% of Class A average daily net assets and up to 1.00% each for Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. The amount of distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was approximately $2,592,900 and $185,900 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended March 31, 2005, are payments retained by Van Kampen of approximately $186,700 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $34,800. 7. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative compliant that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between 32 VAN KAMPEN MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued the parties, the plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of the litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 33 VAN KAMPEN MUNICIPAL INCOME FUND BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.

INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 3.25 percent for Class A shares, a contingent deferred sales charge of 3.00 percent for Class B shares (in year one and declining to zero after year four), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares six years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. The fund's adviser has waived or reimbursed fees and expenses from time to time; absent such waivers/reimbursements the fund's returns would have been lower. SEC yield is a calculation for determining the amount of portfolio income, excluding non- income items as prescribed by the SEC. The subsidized SEC yields reflect some or all of the expenses that the adviser had voluntarily waived. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. Index data source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005 Van Kampen Intermediate Term Municipal Income Fund is managed by the Adviser's Municipal Fixed Income team, which includes Timothy D. Haney, Vice President of the Adviser.(1) MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (which measures the difference in yields between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market posted positive overall returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. (1)Team members may change without notice at any time. 2 PERFORMANCE ANALYSIS The fund returned 0.81 percent for the six months ended March 31, 2005 (Class A shares, unadjusted for sales charge). In comparison, the fund's benchmark index, the Lehman Brothers Municipal Bond Index, returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - -------------------------------------------------------------- LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 0.81% 0.99% 0.52% 1.21% - -------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITION. The fund's underperformance relative to its benchmark was driven largely by its emphasis on the short-to-intermediate segment of the market. While this positioning tends to keep the fund's volatility at a modest level over longer time periods, it can hamper returns over shorter periods when yields on these securities rise more rapidly than those of longer-term bonds. That was the pattern which dominated the market during the review period, and the fund's returns suffered as a result. In fact, intermediate municipal funds as a group underperformed their longer-maturity counterparts over the period. In managing the fund, we continued to focus on trading between liquid, high- quality securities which our analysis identified as compelling total return opportunities. Our strategy involves buying these bonds when they are attractively valued, and selling them when they reach our return targets in order to reinvest the proceeds into bonds with greater future potential for total return. Most of our trading during the six-month period occurred in the 10-to-15 year portion of the market. Our purchases were largely of securities with 15-year maturities but which had more moderate interest rate exposure. The fund remained focused on higher-quality securities. As of the end of the reporting period, approximately 72 percent of the fund's portfolio consisted of securities rated AA or better. We added selectively to the portfolio's holdings of bonds rated BBB or lower in situations where our analysts' research showed sufficiently compelling return opportunity. At the sector level, the fund remained well diversified across the major segments of the municipal market. At the end of the period, the three largest sectors represented in the portfolio were public education, general purpose and public building. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> <Caption> RATINGS ALLOCATIONS AS OF 3/31/05 AAA/Aaa 60.8% AA/Aa 11.0 A/A 11.5 BBB/Baa 8.9 B/B 0.1 Non-Rated 7.7 <Caption> TOP 5 SECTORS AS OF 3/31/05 Public Education 17.9% General Purpose 13.9 Public Building 10.1 Higher Education 10.1 Health Care 9.6 <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 03/31/05 Pennsylvania 11.4% New Jersey 10.1 Ohio 7.2 Missouri 6.9 California 5.3 Illinois 5.2 Florida 5.0 Colorado 4.8 Oregon 4.5 Alabama 4.0 New York 3.0 Texas 2.7 Michigan 2.7 Arizona 2.3 Indiana 2.1 Kansas 2.0 Arkansas 1.9 South Carolina 1.8 Tennessee 1.5 North Carolina 1.5 New Mexico 1.5 South Dakota 1.3 West Virginia 1.2 Connecticut 1.2 Kentucky 0.9 Rhode Island 0.9 Nebraska 0.9 Oklahoma 0.9 District of Columbia 0.9 Maryland 0.6 Wisconsin 0.4 Massachusetts 0.3 Georgia 0.3 Montana 0.3 Louisiana 0.1 </Table> <Table> (continued on next page) </Table> 4 <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 03/31/05 (continued from previous page) Minnesota 0.1 Utah -- ----- Total Long-Term Investments 97.7% Short Term Investments 2.8 Liabilities in Excess of Other Assets -0.5 ----- Total Net Assets 100.0% </Table> Subject to change daily.

You may, however, obtain the Form N-Q filings (as well as the Form N-CSR and N-CSRS filings) by accessing the SEC's Web site, http://www.sec.gov. You may also review and copy them at the SEC's Public Reference Room in Washington, DC. Information on the operation of the SEC's Public Reference Room may be obtained by calling the SEC at 1-800-SEC-0330. You can also request copies of these materials, upon payment of a duplicating fee, by electronic request at the SEC's e-mail address (publicinfo@sec.gov) or by writing the Public Reference section of the SEC, Washington, DC 20549-0102.

The fund delivers a single copy of certain shareholder documents to investors who share an address, even if the accounts are registered under different names. The fund's prospectuses and shareholder reports (including annual privacy notices) will be delivered to you in this manner indefinitely unless you instruct us otherwise. You can request multiple copies of these documents by either calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor Services has received your instructions, we will begin sending individual copies for each account within 30 days. PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD The fund's policies and procedures with respect to the voting of proxies relating to the fund's portfolio securities and information on how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is available without charge, upon request, by visiting our Web site at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and Class C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/1/04 - 3/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your cost would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD* ------------------------------------------------- 10/1/04 3/31/05 10/1/04-3/31/05 Class A Actual..................................... $1,000.00 $1,008.05 $4.71 Hypothetical............................... 1,000.00 1,020.23 4.73 (5% annual return before expenses) Class B Actual..................................... 1,000.00 1,009.89 4.21 Hypothetical............................... 1,000.00 1,020.73 4.23 (5% annual return before expenses) Class C Actual..................................... 1,000.00 1,005.23 7.70 Hypothetical............................... 1,000.00 1,017.23 7.75 (5% annual return before expenses) </Table> * Expenses are equal to the Fund's annualized expense ratio of 0.94%, 0.84%, and 1.54% for Class A, B, and C Shares, respectively, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

N/A=Not Applicable. 22 See Notes to Financial Statements VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) 1. SIGNIFICANT ACCOUNTING POLICIES Van Kampen Intermediate Term Municipal Income Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust (the "Trust"), a Delaware statutory trust, and is registered as a diversified, open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide investors with a high level of current income exempt from federal income tax, consistent with preservation of capital. The Fund commenced investment operations on May 28, 1993 with two classes of common shares, Class A and Class B shares. The distribution of the Fund's Class C shares commenced on October 19, 1993. The Fund registered Class I Shares on December 30, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. Legal expenditures that are expected to result in the restructuring of or a plan of reorganization for an investment are recorded as realized losses. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. Purchasing securities on this basis involves a risk that the market value at the time of delivery may be lower than the agreed upon purchase price resulting in an unrealized loss. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At March 31, 2005, the Fund has $2,742,996 of when-issued and delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. 23 D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income, if any, to its shareholders. Therefore, no provision for federal income taxes is required. At March 31, 2005, the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $119,774,141 ============ Gross tax unrealized appreciation........................... $ 2,212,527 Gross tax unrealized depreciation........................... (512,766) ------------ Net tax unrealized appreciation on investments.............. $ 1,699,761 ============ </Table> E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short term capital gains, which are included in ordinary income for tax purposes. The tax character of distributions paid during the year ended September 30, 2004 was as follows: <Table> Distributions paid from: Ordinary Income........................................... $444,464 Long Term Capital Gain.................................... 437,594 -------- $882,058 ======== </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $157,502 </Table> F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's custody fee was reduced by $1,288 as a result of credits earned on cash balances. 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... .50% Over $500 million........................................... .45% </Table> For the six months ended March 31, 2005, the Adviser waived $60,680 of its investment advisory fee. This represents an annualized rate of .10% of its average daily net assets. This waiver is voluntary in nature and can be discontinued at the Adviser's discretion. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $7,300 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such firm and he and his law firm provide services as legal counsel to the Fund. 24 Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $23,100 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses, respectively, on the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $25,400, representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund, and to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of approximately $106,200 are included in "Other" assets on the Statement of Assets and Liabilities at March 31, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 3.

Sales charges do not represent expenses of the Fund. 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $37,046,404 and $30,158,479 respectively. 5. DERIVATIVE FINANCIAL INSTRUMENTS A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index. The Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In these instances, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. 27 During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in exchange traded futures contracts on U.S. Treasury Securities and typically closes the contract prior to delivery date. These contracts are generally used to manage the Fund's effective maturity and duration. Upon entering into futures contracts, the Fund maintains, an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a future commission merchant pursuant to rules and regulations promulgated in the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended March 31, 2005, were as follows: <Table> <Caption> CONTRACTS Outstanding at September 30, 2004........................... 157 Futures Opened.............................................. 466 Futures Closed..............................................

DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares, and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively, the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and the maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to .25% of Class A average daily net assets and up to 1.00% each of Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. At March 31, 2005, there were no distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") for Class B and Class C shares, respectively. Any unreimbursed receivable may be recovered from future 28 payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in these fees for the ended, are payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $16,400. 7. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file second amended derivative complaint that alleges that the Adviser permitted or recklessly disregarded market timing and later trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, the plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 29 VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND BOARD OF TRUSTEES AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.

INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year six), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect its conversion into Class A shares seven years after purchase. The since inception returns for Class C shares reflects the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. The fund's adviser has waived or reimbursed fees and expenses from time to time; absent such waivers/reimbursements the fund's returns would have been lower. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. The subsidized SEC yields reflect some or all of the expenses that the adviser had voluntarily waived. Yields are subject to change. The Lehman Brothers Municipal Bond Index is generally representative of investment-grade, tax-exempt bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. Index data source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED MARCH 31, 2005 Van Kampen New York Tax Free Income Fund is managed by the Adviser's Municipal Fixed Income team.(1) Members of the team include Dennis S. Pietrzak and John R. Reynoldson, Executive Directors of the Adviser; and Timothy D. Haney, Vice President of the Adviser. MARKET CONDITIONS The six-month period ended March 31, 2005, was characterized by continued short-term interest rate increases, and the specter of rising inflation resulting from record-high crude oil prices. The Federal Open Market Committee (the "Fed") raised the federal funds target rate 100 basis points during the period through a series of four, "measured" 0.25 percent tightenings to 2.75 percent by the end of March. Although rates in the short and intermediate areas of the yield curve shifted upward as the Fed tightened, long-term interest rates fell as buyers did not seem deterred by the prospect of rising inflation. As a result, the yield curve (the difference between short and longer-term yields) flattened and the long end of the municipal market handily outperformed the shorter end. The municipal market posted positive overall returns during the period, though it was not uniformly strong. In contrast to the strong showing by longer-term bonds, shorter-term municipals were hampered by the Fed's tightening and turned in a slightly negative showing. Within the investment-grade segment of the market, yield differentials between BBB-rated municipals and AAA-rated securities were flat to slightly wider, though BBB-rated securities still outperformed high grades due to their higher coupons, while securities rated below investment grade strongly outperformed as investors sought out their higher yields. The Fed's interest rate hikes did not dampen investors' appetites for municipal bonds, as net inflows into municipal bond funds topped $700 million during the period. The supply of new issues was modest during the closing months of 2004 (the first half of the period) before soaring in the opening months of 2005 as long-term issuers rushed to bring securities to market in anticipation of additional interest rate increases in the near term. New York continued to be one of the most active markets in the nation for new issuance during the period, although economic conditions were not uniformly strong. New York's economy continued to improve, and its credit rating was upgraded thanks to a guardedly optimistic outlook for New York City's fiscal health. The city continued to issue Liberty bonds to fund reconstruction efforts at the site of the World Trade Center. By contrast, the northern part of the state continued to struggle economically.

In comparison, the fund's benchmark index, the Lehman Brothers Municipal Bond Index, returned 1.21 percent for the period. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2005 <Table> <Caption> - ---------------------------------------------------------------- LEHMAN BROTHERS CLASS A CLASS B CLASS C MUNICIPAL BOND INDEX 0.67% 0.30% 0.36% 1.21% - ---------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITIONS. One of our key strategies in managing the fund was to position it for rising interest rates. This approach was largely the result of our analysis of interest rates, which remained relatively low by historical standards even after rising from their multi-decade lows earlier. We effected this positioning in two ways. First, we kept the fund's duration (a measure of interest-rate sensitivity) below that of its benchmark. Second, to limit the fund's exposure to areas of the market that would be most likely susceptible to rising rates, we also trimmed the fund's shorter-maturity bonds. We reinvested the proceeds from those sales into bonds with premium coupons and maturities between 25 and 30 years. In addition to offering relatively attractive income streams, these securities positioned the fund to benefit from any future flattening of the yield curve. We kept the fund's exposure well diversified across the major sectors of the New York municipal market. Much of our relative-value trading activity was focused on selling issues that had been pre-refunded and purchasing more attractive securities in sectors such as water and sewer and public education. The fund remained focused on investment-grade securities, with more than 97 percent of the portfolio rated BBB or higher at the end of the period. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> TOP 5 SECTORS AS OF 3/31/05 RATINGS ALLOCATIONS AS OF 3/31/05 General Purpose 21.7% AAA/Aaa 51.1% Higher Education 20.0 AA/Aa 27.5 Public Education 9.6 A/A 14.4 Water & Sewer 8.4 BBB/Baa 4.0 Health Care 8.2 NR 3.0 </Table> Subject to change daily.

The fund delivers a single copy of certain shareholder documents to investors who share an address, even if the accounts are registered under different names. The fund's prospectuses and shareholder reports (including annual privacy notices) will be delivered to you in this manner indefinitely unless you instruct us otherwise. You can request multiple copies of these documents by either calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor Services has received your instructions, we will begin sending individual copies for each account within 30 days. PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD The fund's policies and procedures with respect to the voting of proxies relating to the fund's portfolio securities and information on how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is available without charge, upon request, by visiting our Web site at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 6 Expense Example As a shareholder of the Fund, you incur ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 10/01/04 - 03/31/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, and $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only.

(a) Security is a "step-up" bond where the coupon increases or steps up at a predetermined date. (b) An Inverse Floating Rate security is one where the coupon is inversely indexed to a short-term floating interest rate multiplied by a specific factor. As the floating rate rises, the coupon is reduced. Conversely, as the floating rate declines, the coupon is increased. The price of these securities may be more volatile than the price of a comparable fixed rate security. These instruments are typically used by the Fund to enhance the yield of the portfolio.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen New York Tax Free Income Fund (the "Fund") is organized as a series of the Van Kampen Tax Free Trust, a Delaware statutory trust, and is registered as a non-diversified, open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's investment objective is to provide investors with a high level of current income exempt from federal, New York State and New York City income taxes, consistent with preservation of capital. The Fund seeks to achieve its investment objective by investing at least 80% of its total assets in a portfolio of New York municipal securities that are rated investment grade at the time of purchase. The Fund commenced investment operations on July 29, 1994, with three classes of common shares, Class A, Class B and Class C. The Fund registered Class I Shares on December 30, 2004. There were no sales of Class I Shares for the period ended March 31, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Future contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Fund may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Fund will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payments is made. At March 31, 2005, the Fund had no when-issued and delayed delivery purchase commitments. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies 20 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued and to distribute substantially all of its taxable income, if any, to its shareholders. Therefore, no provision for federal income taxes is required. The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset such losses against any future realized capital gains. At September 30, 2004, the Fund had an accumulated capital loss carryforward for tax purposes of $78,198 which will expire on September 30, 2009. At March 31, 2005, the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $112,091,147 ============ Gross tax unrealized appreciation........................... $ 4,515,572 Gross tax unrealized depreciation........................... (110,153) ------------ Net tax unrealized appreciation on investments.............. $ 4,405,419 ============ </Table> E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended September 30, 2004 was as follows: <Table> <Caption> 2004 Distributions paid from: Ordinary Income........................................... $11,294 Long-term capital gain.................................... -0- ------- $11,294 ======= </Table> As of September 30, 2004, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $271 </Table> Net realized gains and losses may differ for financial reporting purposes primarily as a result of the deferral of losses relating to wash sale transactions. F. EXPENSE REDUCTIONS During the six months ended March 31, 2005, the Fund's custody fee was reduced by $881 as a result of credit earned on cash balances. 21 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... 0.60% Over $500 million........................................... 0.50% </Table> For the six months ended March 31, 2005, the Adviser voluntarily waived $148,518 of its investment advisory fees. This represents .25% of its average net assets for the period. This waiver is voluntary and can be discontinued at any time. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $5,600, representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund is a partner of such firm and he and his law firm provide legal services as counsel to the Fund. Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $20,300 representing Van Kampen Investments or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Fund, which are reported as part of "Other" and "Legal" expenses, respectively, in the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended March 31, 2005, the Fund recognized expenses of approximately $25,500 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of $59,643 are included in "Other" assets on the Statement of Assets and Liabilities at March 31, 2005. Appreciation/ depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 22 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued 3.

INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $12,175,070 and $11,583,337, 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. 24 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued The Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or to generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/ depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in exchange traded futures contracts on U.S. Treasury Bonds and typically closes the contract prior to the delivery date. These contracts are generally used to manage the Fund's effective maturity and duration. Upon entering into futures contracts, the Fund maintains an amount of cash or liquid securities with a value equal to percentage of the contract amount with either a future commission merchant pursuant to rules and regulations promulgated in the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the values of the contract (variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended March 31, 2005, are as follows: <Table> <Caption> CONTRACTS Outstanding at September 30, 2004........................... -0- Futures Opened.............................................. 220 Futures Closed..............................................

DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and the maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to .25% of Class A average daily net assets and up to 1.00% each for Class B and Class C average daily net assets are accrued daily. The annual 25 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. The amount of distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was approximately $446,400 and $2,700 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended March 31, 2005, are payments retained by Van Kampen of approximately $162,900 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $24,300. 7. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative compliant that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, the plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. 26 VAN KAMPEN NEW YORK TAX FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2005 (UNAUDITED) continued The defendants have moved to dismiss each of these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 27 VAN KAMPEN NEW YORK TAX FREE INCOME FUND BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.
