Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 1
President's Letter
Dear Shareowner,
The U.S. stock market rallied sharply through the third quarter of 2012 amid a
sluggish, but nonetheless growing, U.S. economy. We have been cautiously
optimistic about the U.S. from the start of the year, and the economic data
continue to be encouraging. The housing and auto sectors are benefitting from
record-low interest rates. The climate for consumer and business credit has
improved, and inflation appears to be subdued. While corporate profits slowed in
the third quarter, many U.S. companies continue to have strong balance sheets
and to pay attractive dividends* compared to fixed-income securities.
All of these factors contributed to gains for investors who owned riskier
assets, including equities and higher-yielding corporate bonds. Year to date
through the end of the third quarter, the Standard & Poor's 500 Index returned
16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II
Index was up by 12.02% during the same period, while the Barclays Capital
Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a
comparatively sluggish return of 1.70%, as measured by the Barclays Capital
Intermediate Treasuries Index.
Despite this generally positive picture during the first three quarters of 2012,
investors face powerful macroeconomic challenges in the months ahead. These
include the threat of a so-called "fiscal cliff" in the U.S. budget process
after the November elections, the European sovereign-debt crisis, and slowing
growth in both Europe and China. Investors can continue to count on market
volatility tied to these factors, although we remain optimistic that the
underlying economic trends are moving in the right direction.
At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification alone does not assure a
profit or protect against loss in a declining market, we believe in actively
seeking out opportunities in undervalued securities and sectors around the
globe. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy that
works for every investor.
* Dividends are not guaranteed.
2 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
Pioneer's investment professionals focus on finding good opportunities in both
equity and bond markets using the same disciplined investment approach we have
used since 1928. Our strategy is to identify undervalued individual securities
with the greatest potential for success, carefully weighing risk against reward.
Our teams of investment professionals continually monitor and analyze the
relative valuations of different sectors and securities globally to help build
portfolios that we believe can help you achieve your investment goals.
We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 3
Portfolio Management Discussion | 10/31/12
Strong investor demand and limited supply helped produce solid returns from
municipal bond investments during the six months ended October 31, 2012. In the
following interview, David Eurkus discusses the factors that influenced the
performance of Pioneer Municipal High Income Trust during the six-month period.
Mr. Eurkus, senior vice president and portfolio manager at Pioneer, is
responsible for the daily management of the Trust.
Q How did Pioneer Municipal High Income Trust perform during the six months
ended October 31, 2012?
A Pioneer Municipal High Income Trust produced a total return of 8.33% at net
asset value, and 7.53% at market price during the six months ended October
31, 2012. During the same period, the Trust's benchmarks, the Barclays
Capital High Yield Municipal Bond Index and the Barclays Capital Municipal
Bond Index, returned 7.45% and 3.34%, respectively. The Barclays Capital
High Yield Municipal Bond Index is designed to track the performance of
lower-rated municipal bonds. The Barclays Capital Municipal Bond Index is
designed to track the performance of investment-grade municipal bonds.
During the same six months ended October 31, 2012, the average return (at
market price) of the 12 closed end funds in Lipper's High Yield Municipal
Debt Closed End Funds category (which may or may not be leveraged) was
8.75%.
Unlike the Trust, the two Barclays Capital municipal indices do not use
leverage. While the use of leverage can increase investment opportunity, it
also can increase investment risk.
The shares of the Trust were selling at a 9.0% premium to net asset value at
the end of the period.
On October 31, 2012, the standardized 30-day SEC yield on the Trust's shares
was 2.83%.
Q How would you describe the investment environment for municipal bonds during
the six months ended October 31, 2012?
A The municipal market enjoyed healthy inflows of new money during the six
months ended October 31, 2012, from both traditional investors seeking tax
advantages and institutional investors who were attracted by the competitive
yields available from municipal securities compared with taxable
investments. During the period, both investment-grade and higher-yielding,
below-investment-grade municipal securities produced more
4 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
income than comparable-quality and similar-maturity taxable securities, on
an after-tax basis. As demand increased during the six-month period, the
supply of municipal securities remained limited. As a consequence, municipal
bond prices rose and interest rates declined, delivering total returns in
the asset class that often were superior to those available in the taxable
market. In addition to offering attractive relative values, municipal
revenue bonds continued to be perceived as a relatively safe place for
investors' money.
Q What investment strategies did you pursue during the six months ended
October 31, 2012, and how did the strategies affect the Trust's performance?
A In a favorable market for municipal bonds, the Trust outperformed its two
benchmarks, aided by quality security selection in both investment-grade and
high-yield municipals, and the Trust's longer-duration positioning as
compared with the two Barclays Capital municipal indices' weighted average
duration. The longer-duration positioning helped the Trust to capture price
gains as interest rates declined during the period.
We kept the Trust fully invested during the six-month period and maintained
a duration positioning that was longer than that of the benchmarks. In
addition, the Trust's portfolio of investments included many established
positions with adequate call protection that had much higher yields than
those currently available. Call protection limits the issuers' ability to
pre-pay their debt in order to refinance into lower-yielding substitutes.
During the period, we maintained the Trust's traditional emphasis on project
revenue bonds, which are secured by dedicated revenue streams from specific
projects, such as hospitals or airport facilities. We focus the Trust's
investments on these securities because of the reliability of their funding
sources as compared with general obligation bonds, which do not require
dedicated revenue streams and can be more affected by credit rating
downgrades or the general fiscal problems of a municipality or agency.
At the end of the period on October 31, 2012, health care revenue bonds
represented the largest allocation in the Trust's total investment
portfolio, at 17.1% of invested assets, followed by insurance revenue bonds,
which accounted for 14.9% of the Trust's total investment portfolio. Other
project revenue allocations in the Trust's portfolio included those in
education, housing, transportation and pollution control facilities.
As of October 31, 2012, 44.8% of the Trust's total investment portfolio was
invested in securities with investment-grade credit ratings, while 55.2% of
the Trust's total investment portfolio was held in high-yield securities.
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 5
Q What types of investments had a material effect on the Trust's performance
during the six months ended October 31, 2012?
A The Trust's performance during the period benefited from strong results
generated by both the investment-grade and high-yield allocations in the
portfolio, across a range of areas, including the hospital/health care
sector and the transportation and industrial development groups. We believe
the Trust's performance during the period provides evidence of the value of
our disciplined investment process, which relies on basic, fundamental
research and the analysis of individual securities as well as the
reliability of the securities' funding sources.
Among individual Trust holdings during the period, standout performers
included a British Airways transportation revenue bond issued in New York
and an industrial development authority security issued by the Pennsylvania
Economic Development Authority (backed by a U.S. Gypsum project). In the
hospital/health care sector, the Trust saw positive results from several
Massachusetts Health and Education Authority bonds. The Trust owned a
security backed by the Mohegan Sun Casino in Connecticut, which also fared
well during the period, as did holdings of several state revenue bonds
backed by proceeds from tobacco liability settlements.
Among the Trust's investments that detracted from results during the period
were bonds backed by revenues of two continuing care retirement communities,
one in Nassau County, New York, and one issued by the Illinois state
financing authority.
Q How did the level of leverage employed by the Trust change over the six
months ended Sept. 30, 2012?
A At the end of the six-month period ended October 31, 2012, 23.3% of the
Trust's total managed assets were financed by leverage, compared with 24.1%
of the Trust's total managed assets financed by leverage at the start of the
period on May 1, 2012. The decrease was due to changes in the values of
securities in which the Trust invested.
Q What is your investment outlook?
A We continue to see what we believe to be good values and attractive
opportunities in the municipal market, both in high-yield and investment-
grade securities. We believe we will see in the future the continued need
for financing of essential projects, and that need should provide quality
investment opportunities for those who focus on fundamental research of the
strengths and financial reliability of each proposed project. We think
credit research will remain essential for investment success.
6 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
The municipal markets as well as the capital markets in general do face a
number of issues that can affect values, including the continuing political
debate in the U.S. over the country's national debt, levels of taxation, and
discretionary spending policies.
We plan to stay focused on intensive, independent research when selecting
securities for the Trust's portfolio, looking at the different sectors
involved in public finance and examining which areas we believe are most
likely to have secure revenues, and which services are considered to be most
essential. We are watching carefully for new areas of investment
opportunity, which may include financing for charter schools, seaport
facility expansions, toll road construction and maintenance, and energy
production. In the current environment, we also will be paying close
attention to which type of projects may be affected by any change in federal
tax or spending policies.
Please refer to the Schedule of Investments on pages 13-23 for a full listing of
Trust securities.
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 7
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.
A portion of income may be subject to state, federal, and/or alternative minimum
tax. Capital gains, if any, are subject to a capital gains tax.
When interest rates rise, the prices of debt securities held by the Trust will
generally fall. Conversely, when interest rates fall the prices of debt
securities held by the Trust generally will rise.
By concentrating in municipal securities, the Trust is more susceptible to
adverse economic, political or regulatory developments than is a portfolio that
invests more broadly.
Investments in the Trust are subject to possible loss due to the financial
failure of the issuers of the underlying securities and the issuers' inability
to meet their debt obligations.
The Trust may invest up to 20% 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 investment of the Trust's assets in
illiquid securities may restrict the Trust's ability to take advantage of market
opportunities.
The Trust uses leverage through the issuance of preferred shares. Leverage
creates significant risks, including the risk that the Trust's incremental
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. Since February of 2008, regularly scheduled auctions for the Trust's
preferred shares have failed and preferred shareowners have not been able to
sell their shares at auction. The Board of Trustees of the Trust has considered,
and continues to consider, this issue.
The Trust is required to maintain certain regulatory and rating agency asset
coverage requirements in connection with its outstanding preferred shares. In
order to maintain required asset coverage levels, the Trust may be required to
alter the composition of its investment portfolio or take other actions, such as
redeeming preferred shares with the proceeds from portfolio transactions, at
what might be inopportune times in the market. Such actions could reduce the net
earnings or returns to holders of the Trust's common shares over time.
Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering prospectus and in shareowner reports issued from time to time.
These risks may increase share price volatility.
Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

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 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 prices obtained under the Trust's dividend
reinvestment plan.
The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Trust distributions or the sale of Trust shares.
The Barclays Capital Municipal Bond Index is a broad measure of the municipal
bond market. The Barclays Capital High Yield Municipal Bond Index totals over
$26 billion in market value and maintains over 1300 securities. Municipal bonds
in this index have the following requirements: maturities of one year or
greater, sub investment grade (below Baa or non-rated), fixed coupon rate,
issued after 12/31/90, deal size over $20 million, and maturity size of at least
$3 million. Index returns are calculated monthly, assume reinvestment of
dividends and, unlike Trust returns, do not reflect any fees, expenses or sales
charges.
The indices do not employ leverage. It is not possible to invest directly in the
indices.

Various inputs are used in determining the value of the Trust's investments.
These inputs are summarized in the three broad levels below.
Level 1 - quoted prices in active markets for identical securities
Level 2 - other significant observable inputs (including quoted prices for
similar securities, interest rates, prepayment speeds credit
risks, etc.)
Level 3 - significant unobservable inputs (including the Trust's own
assumptions in determining fair value of investments)
Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans are categorized as Level 2, and securities valued using fair
value methods (other than prices supplied by independent pricing services) as
level 3. See Notes to Financial Statements -- Note 1A
The following is a summary of the inputs used as of October 31, 2012, in valuing

28 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
Notes to Financial Statements | 10/31/12 (unaudited)
1. Organization and Significant Accounting Policies
Pioneer Municipal High Income Trust (the Trust) was organized as a Delaware
statutory trust on March 13, 2003. Prior to commencing operations on July 21,
2003, 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 investment
objective of the Trust is to seek a high level of current income exempt from
regular federal income tax, and the Trust may, as a secondary objective, also
seek capital appreciation to the extent that it is consistent with its primary
investment objective.
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, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses, and gain or loss 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
with remaining maturity of more than sixty days are valued at prices
supplied by independent pricing services, which consider such factors as
market prices, market events, quotations from one or more brokers, Treasury
spreads, yields, maturities and ratings. Valuations may be supplemented by
dealers and other sources, as required. The values of interest rate swaps
are determined by obtaining dealer quotations. Equity securities that have
traded on an exchange are valued at the last sale price on the principal
exchange where they are traded. Equity securities that have not traded on
the date of valuation, or securities for which sale prices are not
available, generally are valued using the mean between the last bid and
asked prices. Short-term fixed income securities with remaining maturities
of sixty days or less generally are valued at amortized cost. Money market
mutual funds are valued at net asset value.
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 29
Securities for which independent pricing services are unable to supply
prices or for which market prices and/or quotations are not readily
available or are considered to be unreliable are valued using fair value
methods pursuant to procedures adopted by the Board of Trustees. The Trust
may use fair value methods if it is determined that a significant event has
occurred after the close of the exchange or market on which the security
trades and prior to the determination of the Trust's net asset value.
Examples of a significant event might include political or economic news,
corporate restructurings, natural disasters, terrorist activity or trading
halts. Thus, the valuation of the Trust's securities may differ from
exchange prices.
At October 31, 2012, one security was valued using fair value methods (in
addition to securities valued using prices supplied by independent pricing
services) representing 0.0% of net assets. Inputs used when applying fair
value methods to value a security may include credit ratings, the financial
condition of the company, current market conditions and comparable
securities.
Discount and premium on debt securities are accreted or amortized,
respectively, daily into interest income on a yield-to-maturity basis with a
corresponding increase or decrease in the cost basis of the security.
Interest income, including income bearing cash accounts, is recorded on an
accrual basis.
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.
Gains and losses on sales of investments are calculated on the identified
cost method for both financial reporting and federal income tax purposes.
B. 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. Tax
years for the prior three fiscal years remain subject to examination by
federal and state tax authorities.
The amounts and characterizations of distributions to shareowners for
financial reporting purposes are determined in accordance with federal
income tax rules. Therefore, the sources of the Trust's distributions may be
shown in the accompanying financial statements as from or in excess of net
investment income or as from net realized gain (loss) on investment
transactions, or as from paid-in capital, depending on the type of book/tax
differences that may exist.
30 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
The tax character of current year distributions payable to common and
preferred shareowners will be determined at the end of the current taxable
year. The tax character of distributions paid during the year ended April
30, 2012 was as follows:
----------------------------------------------------------------------------
2012
----------------------------------------------------------------------------
Distribution paid from:
Tax-exempt income $25,801,273
Ordinary income 1,290,517
----------------------------------------------------------------------------
Total taxable distribution $27,091,790
============================================================================
The following shows the components of distributable earnings (losses) on a
federal income tax basis at April 30, 2012:
----------------------------------------------------------------------------
2012
----------------------------------------------------------------------------
Distributable earnings:
Undistributed tax-exempt income $ 8,944,200
Undistributed ordinary income 137,848
Capital loss carryforward (25,495,311)
Post-October loss deferred (8,801,617)
Dividends payable (5,804)
Unrealized appreciation 22,618,184
----------------------------------------------------------------------------
Total $ (2,602,500)
============================================================================
The difference between book-basis and tax-basis unrealized depreciation is
primarily attributable to the difference between book and tax amortization
methods for premiums and discounts on fixed income securities, book/tax
difference in the accrual of income on securities in default, the deferral
of post-October capital losses for tax purposes and other temporary
differences.
C. Automatic Dividend Reinvestment Plan
All common shareowners whose shares are registered in their own names
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 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.
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 31
If a shareowner's shares are held in the name of a brokerage firm, bank or
other nominee, the shareowner can ask the firm or nominee to participate in
the Plan on the shareowner's behalf. If the firm or nominee does not offer
the Plan, dividends will be paid in cash to the shareowner of record. A firm
or nominee may reinvest a shareowner's cash dividends in common shares of
the Trust on terms that differ from the terms of the Plan.
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.
D. Risks
At times, the Trust's investments may represent industries or industry
sectors that are interrelated or have common risks, making the Trust more
susceptible to any economic, political, or regulatory developments or other
risks affecting those industries and sectors. Information regarding the
Trust's principal risks is contained in the Trust's original offering
prospectus, with additional information included in the Trust's shareowner
reports issued from time to time. Please refer to those documents when
considering the Trust's principal risks.
32 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
The Trust may invest in both investment grade and below investment grade
(high-yield) municipal securities with a broad range of maturities and
credit ratings. 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.
2. Management Agreement
Pioneer Investment Management, Inc. (PIM), the Trust's investment adviser, a
wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), manages the
Trust's portfolio. Management fees payable under the Trust's Advisory Agreement
with PIM are calculated daily at the annual rate of 0.60% of the Trust's average
daily managed assets. "Managed assets" means (a) the total assets of the Trust,
including any form of investment leverage, minus (b) all accrued liabilities
incurred in the normal course of operations, which shall not include any
liabilities or obligations attributable to investment leverage obtained through
(i) indebtedness of any type (including, without limitation, borrowing through a
credit facility of the issuance of debt securities), (ii) the issuance of
preferred stock or other similar preference securities, and/or (iii) any other
means. For the six months ended October 31, 2012, the net management fee was
0.60% of the Trust's average daily managed assets, which was equivalent to 0.80%
of the Trust's average daily net assets attributable to the common shareowners.
In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At October 31,
2012, $296,035 was payable to PIM related to management costs, administrative
costs and certain other reimbursements and is included in "Due to affiliates"
and "Administration fee" on the Statement of Assets and Liabilities.
Effective May 1, 2012, PIM has retained Brown Brothers Harriman & Company (BBH)
to provide certain administrative and accounting services to the Trust on its
behalf. For such services, PIM pays BBH a monthly fee at an annual rate of
0.025% of the Trust's average daily managed assets subject to a minimum monthly
fee of $6,250. Previously, PIM had retained State Street Bank & Trust Company
(State Street) to provide such services. PIM paid State Street a monthly fee at
an annual rate of 0.07% of the Trust's average daily managed assets up to $500
million, subject to a minimum monthly fee of $10,000. Neither BBH nor State
Street received compensation directly from the Trust for providing such
services.
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 33
3. Transfer Agents
Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, 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 (Deutsche Bank) is the transfer
agent, registrar, dividend paying agent and auction agent with respect to the
Trust's Auction Preferred Shares (APS). The Trust pays Deutsche Bank an annual
fee, as is agreed to from time to time by the Trust and Deutsche Bank, for
providing such services.
In addition, the Trust reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareowner communications activities such as proxy and
statement mailings and outgoing phone calls.
4. Expense Offset Agreements
The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the six months ended October 31, 2012, the
Trust expenses were not reduced under such arrangement.
5. Interest Rate Swaps
The Trust may enter into interest rate swap transactions to attempt to protect
itself from increasing dividend or interest expense on its leverage resulting
from increasing short-term interest rates. The cost of leverage may rise with an
increase in interest rates, generally having the effect of lower yields and
potentially lower dividends to common shareowners. Interest rate swaps can be
used to "lock in" the cost of leverage and reduce the negative impact that
rising short-term interest rates would have on the Trust's leveraging costs.
An interest rate swap is an agreement between two parties, which involves
exchanging floating rate and fixed rate interest payments for a specified period
of time. Interest rate swaps involve the accrual of the net interest payments
between the parties on a daily basis, with the net amount recorded within the
unrealized appreciation/depreciation of interest rate swaps on the Statement of
Assets and Liabilities. Once the interim payments are settled in cash, at the
pre-determined dates specified in the agreement, the net amount is recorded as
realized gain or loss from interest rate swaps on the Statement of Operations.
During the term of the swap, changes in the value of the swap are recognized as
unrealized gains and losses by "marking-to-market" the value of the swap based
on values obtained from dealer quotations. When the swap is terminated, the
Trust will record a realized gain or loss equal to the difference, if any,
between the proceeds from (or cost of) closing the contract and the cost basis
of the contract. The Trust is exposed to credit risk in the
34 Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12
event of non-performance by the other party to the interest rate swap. Risk may
also arise with regard to market movements in the value of the swap arrangement
that do not exactly offset the changes in the related dividend requirement or
interest expense on the Trust's leverage.
There were no interest rate swap contracts open during the six months ended
October 31, 2012 or outstanding at October 31, 2012.
6. Trust Shares
There are an unlimited number of common shares of beneficial interest
authorized.
Transactions in common shares of beneficial interest for the six months ended
October 31, 2012 and the year ended April 30, 2012 were as follows:
--------------------------------------------------------------------------------
10/31/12 4/30/12
--------------------------------------------------------------------------------
Shares outstanding at beginning of period 22,495,129 22,381,423
Reinvestment of distributions 35,682 113,706
--------------------------------------------------------------------------------
Shares outstanding at end of period 22,530,811 22,495,129
================================================================================
The Trust may classify or reclassify any unissued shares of beneficial interest
into one or more series of preferred shares of beneficial interest. As of
October 31, 2012, there were 4,040 APS as follows: Series A-2,000 and Series
B-2,040.
Dividends on Series A and Series B are cumulative at a rate which is to be reset
every seven days based on the results of an auction. An auction fails if there
are more APS offered for sale than there are buyers. When an auction fails, the
dividend rate for the period will be the maximum rate on the auction dates
described in the prospectus for the APS. Preferred shareowners are not able to
sell their APS at an auction if the auction fails. Since February 2008, the
Trust's auctions related to the APS have failed. The maximum rate for each
series is 110% of the 7 day commercial paper rate or adjusted Kenny rate.
Dividend rates on APS ranged from 0.278% to 0.364% during the six months ended
October 31, 2012.
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, the Trust does not comply with the asset coverage
ratios described in the prospectus for the APS.
The APS 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 APS are also subject to mandatory
redemption at $25,000 per share plus any accumulated or unpaid dividends,
Pioneer Municipal High Income Trust | Semiannual Report | 10/31/12 35
whether or not declared, if certain requirements relating to the composition of
the assets and liabilities of the Trust as set forth in the Statement of
Preferences are not satisfied.
The holders of APS 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. Holders of APS 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.
7. Subsequent Events
The Board of Trustees of the Trust declared on November 5, 2012 a dividend from
undistributed net investment income of $0.095 per common share payable November
30, 2012, to common shareowners of record on November 16, 2012.
Subsequent to October 31, 2012, dividends declared and paid on preferred shares
totaled $15,545 in aggregate for the two outstanding preferred share series
through November 19, 2012.

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.

of Schedule 14A (17 CFR 240.14a-101), or this Item.
There have been no material changes to the procedures by which the

ITEM 11. CONTROLS AND PROCEDURES.
(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.
The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on their evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.
(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.
There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.
The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:
In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose. Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.
ITEM 12. EXHIBITS.
File the exhibits listed below as part of this Form. Letter or number the
exhibits in the sequence indicated.
(a) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.
(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).
Filed herewith.
