Dear Shareowner,
--------------------------------------------------------------------------------
Mature and emerging market economies around the world showed moderate
improvement after a flat second quarter. The U.S. saw some resurgence of
growth, which we expect to continue through the fourth quarter of 2006 and into
2007, although this growth may be slow with housing sector measures down in
recent months. While inflation pressures have risen slightly in recent months,
we believe the United States may now be at the end of the Fed's monetary
tightening cycle. Mature economies, led by Japan, remain firm, as do European
economic prospects, with strong GDP data reflecting the broad-based strength
seen in crucial indicators.

U.S. economic growth was back on track after lackluster market results prior to
Labor Day. Consumer spending rose with receding gas prices, just in time for
the back-to-school season, which retailers now consider the second most
lucrative period after the Christmas season. U.S. economic growth is in line
with our projections; we anticipate U.S. GDP finishing with a level of around
3.0% for 2006.

In our view, the pace of corporate earnings growth should slow amid pressure
from high raw materials costs and moderating economic growth. However, modest
U.S. dollar depreciation and improving growth overseas should offer some
support to U.S. earnings.

The European economy continues to improve and appears to be at its healthiest
in six years, with business confidence showing improvement across sectors and
consumers becoming more optimistic. While business sentiment indicators have
had a tendency to over-estimate growth in recent years, their broad-based
improvement across countries since 2005 is a clear sign that European economic
growth should continue through 2006.

The positive long-term drivers of emerging markets remain in place: improving
domestic growth and inflation stability; structural reform; debt
sustainability; and favorable demographics. Together, the emerging markets'
current account surplus is at record highs while external debt as a percentage
of GDP is at its lowest since 1991.

Letter

In summary, we think that despite the existence of some inflation pressures
seen by the Federal Reserve and its counterparts in developed economies, it
seems as if interest rates will remain mostly unchanged. U.S. economic growth
is expected to remain positive, as it should among the developed nations for
the remainder of 2006. Any further geopolitical issues and rising energy prices
could lead to deceleration, but not a derailment from the current healthy pace
of economic growth, as investment is expected to remain robust, benefiting from
sustained internal and international demand worldwide.

Our cautiously optimistic outlook reinforces the importance of Pioneer's
message that investors should remain diversified, take a long-term view, and
base investment decisions on economic and market fundamentals rather than on
emotion. Our investment philosophy and approach continue to be based on the use
of fundamental research to identify a range of opportunities that offer an
attractive balance of risk and reward to help Trust shareowners work toward
their long-term goals.

Respectfully,

/s/ Osbert M. Hood

Pioneer High Income Trust
--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 9/30/06
--------------------------------------------------------------------------------

The domestic high-yield bond market recovered during the second half of the
six-month period ending September 30, 2006, erasing the effects of a slump that
had pulled down high-yield bond prices early in the period. Lower-quality,
higher-yielding bonds had declined early in the six-month period over concerns
about inflation, high energy prices and rising interest rates. The following is
an interview with Kenneth J. Taubes and Andrew Feltus, who discuss the
performance of Pioneer High Income Trust during the six months. Mr. Taubes is
director of Pioneer's Fixed Income Group, and Mr. Feltus is a member of the
team responsible for the daily management of the Trust.

Q:  How did the Trust perform?

A:  Pioneer High Income Trust performed well based on returns at net asset value
    and even better based on an increase in the market price. For the six
    months ended September 30, 2006, the Trust had a total return of 5.11% at
    net asset value, outperforming the benchmark Merrill Lynch High Yield
    Master II Index, which returned 4.24%. At market price, the total return
    was 11.18% as the Trust's market price rose from a premium of 4.2% over
    net asset value to a premium of 10.2%. The Trust's current SEC 30-day
    yield, based on its market price on September 30, 2006, was 10.67%.

    recent month-end performance results. Current performance may be lower or
    higher than the performance data quoted.

    The performance data quoted represents past performance, which is no
    guarantee of future results. Investment return and principal value will
    fluctuate, and shares, when redeemed, may be worth more or less than their
    original cost.

Q:  How would you describe the investment environment for high-yield bonds
    during the six months?

A:  The first half of the six-month period was dominated by the combination of
    worries about the Federal Reserve Board's ("Fed") interest-rate hikes,
    rising inflationary pressures and higher energy prices. While lower-rated
    bonds, including domestic high-yield corporates and emerging market debt,
    produced modest, positive results very early in this period, they fell
    hard in May and June as concerns grew about risks that inflationary
    threats were

    increasing. Emerging-market debt performed particularly poorly, although
    domestic high-yield corporate bonds also declined during this period when
    investors grew increasingly risk-averse. Equity prices also tended to fall
    during these two months. This trend reversed itself in July, however, as
    investors saw early evidence that economic growth was moderating and that
    inflationary pressures were receding. Investors began anticipating that
    the Fed might be ready to pause in its cycle of interest-rate hikes.
    Spurred on by the news in early August that the Fed indeed was leaving
    short-term interest rates level, emerging market and high-yield debt - as
    well as higher-quality issues - began to rally and they continued to
    perform well through the end of the period on September 30, 2006. The
    rally was enough to generate positive performance for high-yield bonds
    over the six months, with the market generally producing total returns in
    line with bond coupon (stated rate of interest) rates.

Q:  How did you position the Trust's portfolio in this environment?

A:  We started the six-month period in a relatively defensive posture, with a
    healthy cash position and a short duration. (Duration is a measure of a
    bond's price sensitivity to changes in interest rates.) We maintained this
    cautious posture because longer-maturity bonds tend to decline in value
    more than shorter-maturities when interest rates are rising, and
    Treasuries and other high-grade bonds were falling in price. Although we
    believed the economy was basically sound, we reduced our investments in
    the bonds of more cyclical corporations - companies whose earnings are
    closely tied to the ebb and flow of the economic cycle. In particular, we
    cut back our holdings in industries where we saw higher risk - notably
    homebuilders, where there was clear evidence of a major slowdown. We also
    pared back our holdings in industries such as chemicals and media, as well
    as in utilities, where values looked less appealing. We did, however, find
    opportunities in recovering areas, such as airlines.

    At the end of the six months, the Trust's average credit quality was B,
    with 66.5% of assets invested in U.S. high-yield bonds, and 22.9% invested
    in emerging market debt and international high-yield. On September 30,
    2006, approximately 24% of Trust assets were leveraged. The Trust has the
    ability to use leverage, borrowing

                                                                               5

--------------------------------------------------------------------------------

    up to 33% of assets at short-term rates to invest in high-yield bonds.
    This flexibility helped contribute to performance.

Q:  What types of investments had the greatest impact on performance?

A:  Our positions in airline and airline-related bonds gave some significant
    support to performance. As the airlines recovered from their downturn, our
    investments in bonds such as those of AMR, parent of American Airlines,
    and of Continental Airlines, did very well. We also have investments in
    municipal bonds backed by airport properties, and they also did well.
    These holdings included investments in securities backed by revenues from
    British Air, Northwest Airlines and U.S. Air. Late in the period, we took
    profits and reduced our positions in these securities when we believed
    they had reached full value.

    Other holdings that helped support results included bonds of companies
    that re-structured themselves and were able to buy back their outstanding
    debt, including: Hanger Orthopedic Group, Inc., a producer of prosthetics
    and other orthopedic devices; and J. Ray McDermott, an oil services
    company specializing in marine operations. Other positions that helped
    performance included securities of several companies that bought back debt
    after issuing new equity, including Dollar Financial Group, a company
    specializing in providing services to low- and middle-income customers;
    Warner Chilcott Corp., a pharmaceutical corporation; and Altra Industrial
    Motion, a manufacturer of logistics support systems. Individual
    investments that supported performance included bonds of Duane Reade,
    Inc., a company operating pharmaceutical and convenience stores in the New
    York metropolitan area. The Duane Reade bonds, which earlier had been a
    detractor from Trust performance, recovered in value as the company was
    able to report progress in its turnaround program.

    We did have some disappointing investments, including bonds of several
    companies vulnerable to the housing industry slump. They included
    securities of home builders William Lyon Homes, Inc. and WCI Communities,
    Inc. as well as bonds of Builders FirstSource, Inc. and of U.S. Concrete,
    Inc., both of which supply materials to the building construction
    industry.

Pioneer High Income Trust
--------------------------------------------------------------------------------

Q:  What is your investment outlook?

A:  We believe the economy is fundamentally healthy. While recent weakness in
    the housing industry may lead to a slowing of economic growth, the economy
    should receive some stimulus as a weaker dollar increases the
    competitiveness of companies exporting to other countries. We think
    corporations are likely to continue to invest to expand and improve their
    efficiency, while the consumer-sensitive industries should benefit from
    low unemployment levels. As long as the economic expansion is maintained,
    high-yield issuers should be able to grow and pay their debt obligations,
    and default rates should remain low. Although the difference between the
    yields of high-yield and high-grade bonds are relatively narrow, we think
    these narrow ranges can be justified by the strong fundamentals of
    high-yield issuers. We believe high-yield investors have a reasonable
    opportunity to realize returns consistent with coupon levels, with some
    opportunity for price appreciation.

    Investors in the Trust should remain mindful that if short-term interest
    rates were to rise further and add to the Trust's borrowing costs, the
    ability to sustain present dividend levels could be affected.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. The Trust may invest in securities of issuers that
are in default or that are in bankruptcy.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

When interest rates rise, the prices of fixed-income securities in the Trust
will generally fall. Conversely, when interest rates fall the prices of
fixed-income securities in the Trust will generally rise. Investments in the
Trust are subject to possible loss due to the financial failure of underlying
securities and their inability to meet their debt obligations.

The Trust may invest up to 50% of its total assets in illiquid securities.
Illiquid securities may be difficult to dispose of at a fair price at the times
when the Trust believes it is desirable to do so and their market price is
generally more volatile than that of more liquid securities. Illiquid
securities are also more difficult to value and

                                                                               7

--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 9/30/06                            (continued)
--------------------------------------------------------------------------------

investment of the Trust's assets in illiquid securities may restrict the
Trust's ability to take advantage of market opportunities.

The Trust may use leverage through the issuance of preferred shares with an
aggregate liquidation preference of up to 331/3% of the Trust's total assets
after such issuance. Leverage creates significant risks, including the risk
that the Trust's income or capital appreciation will not be sufficient to cover
the cost of leverage, which may adversely affect the return for the holders of
common shares.

Risks of investing in the Trust are discussed in greater detail in the Trust's
registration statement on Form N-2 relating to its common shares.

   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   Performance data shown represents past performance. Past performance is no
   guarantee of future results. Investment return and market price will
   fluctuate, and your shares may trade below net asset value ("NAV"), due to
   such factors as interest rate changes, and the perceived credit quality of
   borrowers.

   Total investment return does not reflect broker sales charges or
   commissions. All performance is for common shares of the Trust.

   Closed-end funds, unlike open-end funds, are not continuously offered.
   There is a one-time public offering and, once issued, shares of closed-end
   funds are sold in the open market through a stock exchange and frequently
   trade at prices lower than their NAV. NAV is total assets less total
   liabilities, which includes preferred shares, divided by the number of
   common shares outstanding.

   When NAV is lower than market price, dividends are assumed to be reinvested
   at the greater of NAV or 95% of the market price. When NAV is higher,
   dividends are assumed to be reinvested at market price.

   The performance table and graph do not reflect the deduction of fees and
   taxes that a shareowner would pay on Trust distributions or the redemption
   of Trust shares.

   Index comparison begins April 30, 2002. The Merrill Lynch High Yield Master
   II Index is a commonly accepted measure of the performance of high yield
   securities. 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 an Index.

                                                                              11

NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)

1. Organization and Significant Accounting Policies

Pioneer High Income Trust (the "Trust") was organized as a Delaware statutory
trust on January 30, 2002. Prior to commencing operations on April 26, 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.

The Trust invests in below investment grade (high-yield) debt securities, loans
and preferred stocks. Certain high-yield securities held by the Trust 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 U.S.
generally accepted accounting principles that require the management of the
Trust to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, and the reported amounts of income,
expenses and gains and losses on investments during the reporting year. Actual
results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A.  Security Valuation

    Security transactions are recorded as of trade date. Fixed-income
    securities are valued at prices supplied by independent pricing services,
    which consider such factors as Treasury spreads, yields, maturities and
    ratings. Valuations may be supplemented by dealers and other sources, as
    required. Equity securities are valued at the last sale price on the
    principal exchanges where they are traded. 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 NYSE. The values of such securities used in
    computing the net

32


Pioneer High Income Trust
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

    asset value of the Trust's shares are determined as of such times. The
    Trust may also use the fair value of a security, including a non-U.S.
    security, when the closing market price on the primary exchange where the
    security is traded no longer accurately reflects the value of the security
    as of the close of the exchange. As of September 30, 2006, the Trust had
    no fair valued securities. Temporary cash investments are valued at
    amortized cost.

    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. Discount and premium on debt
    securities are accreted or amortized, respectively, daily, on an effective
    yield to maturity basis and are included in interest income. 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.

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes.

    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.

    Information regarding the Trust's principal risks is contained in the
    Trust's prospectus, with additional information included in the Trust's
    Shareowner reports from time to time. Please refer to those documents when
    considering the Trust's risks. At times, the Trust's investments may
    represent industries or industry sectors that are interrelated or have
    common risks, making it more susceptible to any economic, political, or
    regulatory developments or other risks affecting those industries or
    sectors. Under normal market conditions, the Trust invests at least 80% of
    its assets in below investment grade (high-yield) debt securities, loans
    and preferred stocks. Because the Trust's investments will be concentrated
    in the high-yield securities, it will be subject to risks of such
    securities. Below investment grade securities are commonly

                                                                              33

NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)                  (continued)
--------------------------------------------------------------------------------

    referred to as "junk bonds" and are considered speculative with respect to
    the issuer's capacity to pay interest and repay principal.

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 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 4).

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.

34


Pioneer High Income Trust
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

    The amounts and characterizations of distributions to shareowners for
    financial reporting purposes are 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.

    The tax character of current year distributions paid to common and
    preferred shareowners will be determined at the end of the fiscal year.
    The distribution during the year ended March 31, 2006 was as follows:

--------------------------------------------------------------------------------


    The difference between book basis and tax basis unrealized appreciation is
    primarily attributable to the tax deferral of losses on straddles and wash
    sales, the realization for tax purposes of unrealized gains on certain
    foreign currency contracts, the difference between book and tax
    amortization methods for premiums and discounts on fixed income securities
    and difference between book and tax in the accrual of income on securities
    in default.

                                                                              35

--------------------------------------------------------------------------------

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. Pioneer Investment
    Management, Inc. ("PIM"), the Trust's investment adviser 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 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
    payments in lieu of dividends on the securities loaned. Unrealized gain or
    loss on the fair value of the loaned securities that may occur during the
    term of the loan will be for the 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
    sponsored 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 without penalty by notifying
    American Stock Transfer & Trust

36


Pioneer High Income Trust
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

    Company, the agent for shareowners in administering the Plan (the "Plan
    Agent"), in writing 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
    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

Pioneer Investment Management, Inc. ("PIM"), a wholly owned indirect subsidiary
of Unicredito Italiano S.p.A. ("Unicredito Italiano") 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

                                                                              37

preference of any outstanding preferred shares. At September 30, 2006, $288,516
was payable to PIM related to management fees.

In addition, under PIM's management and administration agreements, certain
other services and costs are paid by PIM and reimbursed by the Trust. For the
six months ended September 30, 2006, the Trust recorded $77,864 as
"Administrative reimbursements" on the Statement of Operations.

PIM has retained Princeton Administrators, LLC., to provide certain
administrative services to the Trust on its behalf. PIM pays Princeton
Administrators, LLC., a monthly fee at an annual rate of 0.07% of the average
weekly value of the Trust's managed assets, subject to a minimum monthly fee of
$10,000. Princeton Administrators, LLC 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 American Stock Transfer & Trust Company, 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, 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. Forward Foreign Currency Contracts

During the six months ended September 30, 2006, 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 contracts, the
Trust may close out such contracts by entering into an offsetting hedge
contract.

There are an unlimited number of common shares of beneficial interest
authorized. Of the 27,000,668 common shares of beneficial interest outstanding
at September 30, 2006 PIM owned 6,981 shares.

Transactions in common shares of beneficial interest for the six months ended

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, 2006, there were 6,040 AMPS as follows: Series M7-2,020,
Series W28-2,020 and Series TH7-2,000.

Dividends on Series M7 and Series TH7 are cumulative at a rate, which is reset
every seven days based on the results of an auction. Dividends on Series W28
are also cumulative at a rate reset every 28 days based on the results of an
auction. Dividend rates ranged from 4.58% to 5.36% during the six months ended
September 30, 2006.

                                                                              39


Pioneer High Income Trust
--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)                  (continued)
--------------------------------------------------------------------------------

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
management investment company or changes in its fundamental investment
restrictions.

6. New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN
48"). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in
the course of preparing the Trust's tax returns to determine whether the tax
positions will "more-likely-than-not" be sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period. Adoption
of FIN 48 is required for fiscal years beginning after December 15, 2006 and is
to be applied to all open tax years as of the effective date.

40


Pioneer High Income Trust
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

At this time, management is evaluating the implications of FIN 48 and any
impact in the financial statements has not yet been determined.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements ("SFAS 157"), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Trust's financial statement disclosures.

7. Subsequent Events

Subsequent to September 30, 2006, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.1375 per common share
payable October 31, 2006, to shareowners of record on October 17, 2006.

For the period October 1, 2006 to October 31, 2006, dividends declared on
preferred shares totaled $653,967 in aggregate for the three outstanding
preferred share series.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 firm, the scope of the Audit
