Gross domestic product, a tally of all goods and services produced in the United States, expanded, thanks to increased personal consumption, housing and business spending, low short-term interest rates and lower taxes on individuals. While broader market indicators managed small gains, the NASDAQ Composite rose sharply in the third quarter as investors sensed that companies might soon boost technology outlays. September's dip in consumer expectations linked to slow job creation, plus cutbacks in OPEC oil production, drove markets off their highest levels. Investors also kept an eye on the news, as U.S. troops came under daily fire in Iraq and tensions elsewhere remained. As the economy appeared to strengthen, investors who had sought safety in U.S. Treasury issues grew less risk-averse. As a result, corporate bonds moved broadly higher and the Treasury bond rally stalled. Some of the biggest gains were recorded among lower-rated, high-yield bonds whose issuers often depend on a strong economy to boost earnings. Bonds in emerging and developed markets also did well, as economies stabilized and currencies rose against the slumping U.S. dollar. Stocks and bonds, bonds and stocks Over the past few years, investor sentiment has swung from stocks to bonds and back again, from U.S. government securities to corporate and international issues. Each sector has spent time in the spotlight or back stage, delivering periods of stronger or weaker performance relative to one another. With sectors constantly moving in and out of favor, how can you increase your chances of holding investments that are performing well? By owning several kinds of securities, not just one or two. Through a process called asset allocation, you can create an investment mix that reflects your needs, taking into account such factors as your age, your financial goals and their timing, and, of course, your comfort level where risk is concerned. Asset allocation is only one area in which a qualified investment professional can serve you well. Ask your advisor to review how shifting markets may have affected your asset allocation recently. And if you've never thought about asset allocation before, now is the best time to start. Like everyone at Pioneer, I appreciate your continued confidence in our products and services.

The Merrill Lynch High Yield Master II Index is a broad-based measure of the performance of the non-investment grade U.S. domestic bond market. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in the Index. Past performance does not guarantee future results. Return and principal value fluctuate, and your shares, when redeemed, may be worth more or less than their original cost. The performance table and graph do not reflect the deduction of taxes and fees that a shareowner would pay on Trust distributions of the redemption of Trust shares. 3 Pioneer High Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 9/30/03 - -------------------------------------------------------------------------------- As evidence steadily accumulated that the domestic economy finally was strengthening and growth was beginning to accelerate, high-yield bonds and other corporate-backed fixed-income securities rebounded robustly during the six months ended September 30, 2003. The following is an interview with Kenneth J. Taubes, who discusses the Trust's performance during the period. Mr. Taubes, head of Pioneer's Fixed Income Group, oversees the team responsible for the daily management of the Trust. Q: How has the portfolio performed? A: During a period of rising expectations for both economic growth and corporate profitability, the portfolio delivered excellent performance. For the six months ended September 30, 2003, Pioneer High Income Trust had a total return of 18.90% at net asset value and 11.59% at market price, with a premium of market price to net asset value of 1.26% on September 30. The benchmark Merrill Lynch High Yield Master II Index returned 12.90% during the same period. We also continued to meet our goal of providing superior income. On September 30, the Trust's 30-day SEC yield was 11.49%. Q: What factors contributed to the strong performance? A: The Trust benefited from both a favorable environment and superior security selection. The rally in virtually all corporate securities had begun in late 2002 when the Federal Reserve lowered short-term interest rates once again. That rebound picked up steam in early 2003, at the start of the fiscal period, when evidence grew that corporate earnings finally were starting to accelerate. Other factors also raised expectations about the economy and supported the high-yield bond market. Leading economic indicators became more positive and Congress approved President Bush's tax-cut proposals, giving further immediate stimulus to the economy. Meanwhile, the weakening U.S. dollar helped U.S. manufacturers by making their products more competitive overseas and imports less competitive within the United States. With the improvement in performance of corporate securities, high-yield bonds outperformed investment-grade corporates as well as Treasury and government agency bonds, which began to suffer some price erosion as interest rates on Treasures with maturities 4 Pioneer High Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- of five years or longer started to rise. As interest rates rise, bond prices tend to decline. Q: What were your principal strategies? A: The principal emphasis was in U.S. corporate bonds. These bonds accounted for 75% of Trust assets at the start of the fiscal period, on April 1, and comprised 79% of Trust assets on September 30. Of that amount, 71% were invested in below-investment grade bonds and 8% in investment grade securities. The balance of the assets was invested in high-yielding securities issued by foreign companies and governments. These latter investments, in addition to any gains realized in local currencies, also benefited from the rising value of the foreign currencies against the weakening U.S. dollar. Within the high-yield corporate sector, we tended to emphasize bonds of cyclical companies that had the greatest potential to do well in an expanding economy. These investments included industries such as commodities, basic materials and transportation. Q: What types of investments most affected Trust performance? A: Among our investments in commodities and basic materials, we had particularly strong performance from two mining companies, Phelps-Dodge and Freeport-McMoRan. Within the transportation sector, we had good results from bonds issued by some of the stronger airlines, such as Continental and Northwest. Performance also benefited from investments in high-yield municipal bonds backed by revenues from airport facilities. These issues included securities backed by revenues from Continental Airline gates and maintenance facility in New Jersey, Northwest Air gates in Detroit, British Airways gates in New York, and U.S. Airways gates in Charlotte, N.C. We had disappointing results, however, from some chemical industry bonds that, despite positive returns, underperformed the high-yield market. Among the disappointments were bonds issued by Huntsman ICI and Lyondell Chemical. Also detracting from performance were bonds issued by Constar, the manufacturer of plastic containers commonly used by the soft drink industry. Cool weather during the spring months resulted in weak soft drink sales and poor sales for Constar. 5 Pioneer High Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 9/30/03 (continued) - -------------------------------------------------------------------------------- Q: What is your investment outlook? A: We believe that the economy and corporate profits should continue to grow, improving corporate balance sheets and supporting the performance of high-yield corporate bonds. Corporate bonds in general have the potential to continue to outperform U.S. Treasury and government agency bonds as the economic expansion continues and higher-quality securities become vulnerable to potential price loss as interest rates rise. While the outlook for high-yield bonds appears to be favorable, investors should have realistic expectations and not anticipate that returns will be as high as they have been for the past six months.

Pioneer High Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 9/30/03 (unaudited) - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer High Income Trust (the "Trust") was organized as a Delaware business trust on January 30, 2002. Prior to commencing operations on April 25, 2002, the Trust had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended, and the sale and issuance to Pioneer Investment Management, Inc. (PIM), the Trust's investment adviser, a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), of 6,981 shares of beneficial interest at an aggregate purchase price of $100,003. PIM has reimbursed the amount by which the aggregate of all the Trust's organizational expenses and offering costs (other than the sales load) exceeded $0.03 per share of the common offering. The investment objective of the Trust is to seek a high level of current income and the Trust may seek capital appreciation to the extent consistent with its investment objective. The Trust invests in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into equity securities of the issuer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Trust's financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America that require the management of the Trust to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, and expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Trust, which are in conformity with those generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. Securities are valued at prices supplied by independent pricing services, which 21 Pioneer High Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 9/30/03 (unaudited) (continued) - -------------------------------------------------------------------------------- consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the New York Stock Exchange. The values of such securities used in computing the net asset value of the Trust's shares are determined as of such times. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Trust becomes aware of the ex-dividend data in the exercise of reasonable diligence. Market discount and premium on fixed income securities are accreted or amortized daily on an effective yield to maturity basis. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the underlying monthly paydowns. Interest income, including income on interest bearing cash accounts, is recorded on an accrual basis. Temporary cash investments are valued at amortized cost. The Trust's investments in foreign markets or countries with limited developing markets may subject the Trust to a greater degree of risk than in a developed market. These risks include disruptive political or economic conditions and the possible imposition of adverse governmental laws or currency exchange restrictions. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Trust are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in 22 Pioneer High Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in market price of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Trust enters into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross-hedge against either specific investment transactions (settlement hedges) or portfolio positions (portfolio hedges). All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Trust's financial statements. The Trust records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 5). D. Federal Income Taxes It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The characterization of distributions to shareowners for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Trust's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment and foreign currency transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. 23 Pioneer High Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 9/30/03 (unaudited) (continued) - -------------------------------------------------------------------------------- The tax character of distributions paid during the period ended March 31, 2003 was as follows: - -------------------------------------------------------------------------------- 2003 Distributions paid from: Ordinary Income $37,808,117 Net long-term capital gains - ----------- Total taxable distribution $37,808,117 =========== - -------------------------------------------------------------------------------- The following shows components of distributable earnings on a federal income tax basis at March 31, 2003. These amounts do not include the capital loss carryforward. - -------------------------------------------------------------------------------- Undistributed ordinary income $3,439,995 Undistributed long-term gains - Unrealized appreciation 1,032,717 ---------- Total $4,472,712 ========== - -------------------------------------------------------------------------------- The difference between book/basis and tax-basis unrealized depreciation is primarily attributable to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on certain foreign currency contracts, and differences in the accrual of income on securities in default. E. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Trust's custodian, or subcustodians. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. F. Securities Lending The Trust lends securities in its portfolio to certain broker-dealers or other institutional investors, with the Trust's custodian acting as the lending agent. When entering into a loan, the Trust receives 24 Pioneer High Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- collateral which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Trust also continues to receive interest or dividends on the securities loaned and unrealized gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for account of the Trust. The loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Trust has the right under the securities lending arrangement to recover the securities on loan from the borrower on demand. The Trust invests cash collateral in the Securities Lending Investment Fund which is managed by Brown Brothers Harriman & Co., the Trust's custodian. G. Automatic Dividend Reinvestment Plan All common shareowners automatically participate in the Automatic Dividend Reinvestment Plan (the "Plan"), under which participants receive all dividends and capital gain distributions (collectively, "dividends") in full and fractional common shares of the Trust in lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time by notifying Mellon Investor Services LLC, the agent for shareowners in administering the Plan (the "Plan Agent"), prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Whenever the Trust declares a dividend on common shares payable in cash, participants in the Plan will receive the equivalent in common shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized common shares from the Trust or (ii) by purchase of outstanding common shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend the net asset value per common share is equal to or less than the market price per share plus estimated brokerage trading fees ("market premium"), the Plan Agent will invest the dividend amount in newly issued common shares. The number of newly issued common shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per common share on the date the 25 Pioneer High Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 9/30/03 (unaudited) (continued) - -------------------------------------------------------------------------------- shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per common share is greater than the market value ("market discount"), the Plan Agent will invest the dividend amount in common shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued common shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement PIM manages the Trust's portfolio. Management fees are calculated weekly at the annual rate of 0.60% of the Trust's average weekly managed assets. "Managed assets" is the average weekly value of the Trust's total assets minus the sum of the Trust's liabilities, which liabilities exclude debt related to leverage, short-term debt and the aggregate liquidation preference of any outstanding preferred shares. In addition, under PIM's management and administration agreements, certain other services and costs are paid by the Trust. PIM has retained Princeton Administrators, L.P., an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, to provide certain administrative services to the Trust on its behalf. PIM pays Princeton Administrators, L.P. a monthly fee at an annual rate of 0.10% of the average weekly value of the Trust's managed assets, subject to a minimum monthly fee of $10,000. Princeton Administrators, L.P. receives no compensation directly from the Trust. 3. Transfer Agents Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency agreement with Mellon Investor Services LLC, provides substantially all transfer agent and shareowner services related to the Trust's common shares at negotiated rates. Deutsche Bank Trust Company Americas is the transfer agent, registrar, 26 Pioneer High Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- dividend paying agent and redemption agent with respect to the Trust's Auction Market Preferred Shares (AMPS). The Trust pays Deutsche Bank Trust Company Americas an annual fee, as is agreed to from time to time by the Trust and Deutsche Bank Trust Company Americas, for providing such services. 4. Expense Offsets The Trust may enter into certain expense offset arrangements resulting in a reduction in the Trust's total expenses. As of September 30, 2003, the Trust's expenses were not reduced under such arrangements. 5. Forward Foreign Currency Contracts During the six months ended September 30, 2003, the Trust had entered into contracts that obligate the Trust to deliver currencies at specified future dates. At the maturity of a contract, the Trust must make delivery of the foreign currency. Alternatively, prior to the settlement date of the portfolio hedge, the Trust may close out such contracts by entering into an offsetting hedge contract. At September 30, 2003, the Trust had no forward currency settlement contracts. The Trust's gross outstanding portfolio hedge contracts receivable and payable were $20,682,000 and $20,945,059, respectively, resulting in a net payable of $263,059. 6. Trust Shares There are an unlimited number of common shares of beneficial interest authorized. Of the 26,723,270 common shares of beneficial interest outstanding at September 30, 2003 PIM owned 6,981 shares. During the six months ended September 30, 2003 and the period ended March 31, 2003, the Trust issued 49,195 and 67,094 shares, respectively, in connection with the Trust's dividend reinvestment plan. The Trust may classify or reclassify any unissued common shares of beneficial interest into one or more series of preferred shares of beneficial interest. As of September 30, 2003, there were 6,040 AMPS ("preferred shares") as follows: Series M7-2,020, Series W28-2,020 and Series TH7-2,000. On August 1, 2003, the Trust reclassified and issued 2,000 shares of common shares into Series TH. Estimated offering costs of $166,972 and underwriting discounts of $500,000 have been charged to paid-in capital. 27 Pioneer High Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 9/30/03 (unaudited) (continued) - -------------------------------------------------------------------------------- Dividends on Series M7 AMPS and Series TH7 AMPS are cumulative at a rate which is reset every seven days based on the results of an auction. Dividends on Series W28 AMPS are also cumulative at a rate reset every 28 days based on the results of an auction. Dividend rates ranged from 1.00% to 1.35% during the six months ended September 30, 2003. The Trust may not declare dividends or make other distributions on its common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred shares would be less than 200%. The AMPS are redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared. The AMPS are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Agreement and Declaration of Trust are not satisfied. The holders of AMPS have voting rights equal to the holders of the Trust's common shares (one vote per share) and will vote together with holders of the common shares as a single class. However, holders of AMPS are also entitled to elect two of the Trust's Trustees. In addition, the Investment Company Act of 1940, as amended, requires that along with approval by shareowners that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the preferred shares and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. 7. Subsequent Events Subsequent to September 30, 2003 the Board of Trustees of the Trust declared a dividend from undistributed net investment income of $0.1375 per common share payable October 31, 2003, to shareowners of record on October 20, 2003. 28 Pioneer High Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- For the period October 1, 2003 to October 31, 2003, dividends declared on preferred shares totaled $145,045 in aggregate for the three outstanding preferred share series. ADDITIONAL INFORMATION (unaudited) During the period, there have been no material changes in the Trust's investment objective or fundamental policies that have not been approved by the shareowners. There have been no changes in the Trust's charter or By-Laws that would delay or prevent a change in control of the Trust which have not been approved by the shareowners. There have been no changes in the principal risk factors associated with investment in the Trust. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Trust's portfolio. Notice is hereby given in accordance with Section 23(c) of the Investment Company Act of 1940 that the Trust may purchase, from time to time, its common shares in the open market. 29 Pioneer High Income Trust - -------------------------------------------------------------------------------- RESULTS OF SHAREOWNER MEETING - -------------------------------------------------------------------------------- On October 28, 2003, the Trust held a special meeting of shareowners to select two trustees.
