President's Letter

Dear Shareowner,

When we look at the U.S. economy heading into the final quarter of 2013, we
continue to see slow, but steady, growth. Employment has also been rising
steadily, but only modestly. Consumer incomes, savings, wealth, and
debt-servicing capacity have been solid buttresses for the recovering housing
and auto industries. Industrial activity is growing only modestly, but current
corporate profits are generally solid and balance sheets appear able to support
needed capital spending and dividend* payouts. The scaled-back "fiscal cliff"
tax increases and spending cuts have meaningfully cut the budget deficit without
driving the economy into recession. In addition, we feel that continuing slack
in labor markets and capacity utilization offers the potential for continuing
growth without bottlenecks and rising inflation.

After observing the strengthening economic trends, the Federal Reserve (the Fed)
hinted that it might begin scaling back its "QE" quantitative easing program
later in 2013 and could terminate its bond purchases altogether sometime in
2014. In September, however, the Fed surprised many market participants by
deciding not to start scaling back QE yet. The Fed has also said that short-term
interest rates are likely to remain near zero for some time to come, given that
inflation remains subdued and unemployment remains too high.

As September ended, Congress had not yet passed a continuing resolution to
prevent a government shutdown, nor had it raised the debt ceiling, and a quick
resolution to the impasse appeared unlikely. The U.S. government's partial
shutdown in October rattled the markets to a degree, but did not immediately
have a significant negative impact on the economy or capital markets.

There are certainly risks and uncertainties that continue to plague the global
economy as we head into the final months of the year. The European economy
remains weak, though it is beginning to show signs of stabilization, and a
number of countries in the emerging markets have experienced difficulties.
Still, a potential ending of the European recession, continuing economic
improvement in Japan in response to the new government's easing policies, and a
"soft landing" of 7% growth in China could very well result in an improving
global outlook over the remainder of 2013 and in 2014.

There are also geopolitical worries abroad and the aforementioned political
fights at home, and while most of the widely recognized risks we've outlined may
already be "priced into" the market, we believe investors should continue to
expect market volatility.

The Fed's aggressive monetary policies and fears about economic growth had
helped drive long-term Treasury yields to unsustainably low levels; the return
to more normal levels has resulted in disappointing returns for bond investors
during the first nine months of 2013, but the stock market has delivered
double-digit returns to equity investors who were willing to brave the "wall of
worry".

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 there are still
opportunities for prudent investors to earn attractive returns. 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, keeping in mind that there is no single best strategy that
works for every investor.

Pioneer's investment teams have, since 1928, sought out attractive opportunities
in global equity and bond markets, using in-depth research to identify
undervalued individual securities, and using thoughtful risk management to
construct portfolios which balance potential risks and reward in an
ever-changing world.

We encourage you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank
you for investing with Pioneer.

Sincerely,

/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 9/30/13

Market sentiment toward municipal bonds - especially higher-yielding municipals
- abruptly turned negative in the spring of 2013, undermining the performance of
the asset class during the six-month period ended September 30, 2013. In the
following interview, David Eurkus and Jonathan Chirunga discuss the factors that
influenced the performance of Pioneer Municipal High Income Advantage Trust
during the six-month period. Mr. Eurkus, a senior vice president and a portfolio
manager at Pioneer, and Mr. Chirunga, a vice president and a portfolio manager
at Pioneer, are responsible for the day-to-day management of the Trust.

Q   How did the Pioneer Municipal High Income Advantage Trust perform during the
    six-month period ended September 30, 2013?

A   Pioneer Municipal High Income Advantage Trust returned -7.87% at net asset
    value and -9.67% at market price during the six-month period ended September
    30, 2013. During the same six-month period, the Trust's benchmarks, the
    Barclays Municipal Bond Index and the Barclays High Yield Municipal Bond
    Index, returned -3.15% and -6.92%, respectively. The Barclays Municipal Bond
    Index is an unmanaged measure of the performance of investment-grade
    municipal bonds, while the Barclays High Yield Municipal Bond Index is an
    unmanaged measure of the performance of lower-rated municipal bonds. Unlike
    the Trust, the two Barclays Indices do not use leverage. While use of
    leverage increases investment opportunity, it also increases investment
    risk. During the same six-month period, the average return (at market price)
    of the 11 closed end funds in Lipper's High Yield Municipal Debt Closed End
    Funds category (which may or may not be leveraged) was -6.71%.

    The shares of the Trust were selling at a 12.40% premium to net asset value
    at the end of the period, on September 30, 2013.

    On September 30, 2013, the Trust's standard 30-day SEC yield was 8.76*.

Q   How would you describe the investment environment in the municipal bond
    market during the six-month period ended September 30, 2013?

A   Municipal bonds - and especially high-yielding municipals - had been
    enjoying a favorable investment backdrop until a series of events began to
    undermine investors' confidence.

    One major development was the well-publicized bankruptcy filing by the City
    of Detroit, which raised worries about the financial stability and credit
    quality of other communities. Those worries only increased after another

*   The 30-day SEC yield is a standardized formula that is based on the
    hypothetical annualized earning power (investment income only) of the
    Trust's portfolio securities during the period indicated.

4 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13


    significant piece of news hit the market--high-profile media warnings about
    the financial problems afflicting the Commonwealth of Puerto Rico, which
    might have trouble meeting its obligations without additional borrowing.

    In the ensuing weeks, the market for municipal bonds became increasingly
    volatile, as liquidity dried up when institutional investors moved to sell
    their holdings, and buyers, at the same time, held back. Municipal bonds
    declined sharply in price, significantly underperforming U.S. Treasuries and
    many other segments of the fixed-income market. Because of their greater
    sensitivity to credit risk, lower-rated municipal bonds with higher yields
    performed much worse than investment-grade municipals during the period.

Q   How did the market environment and your investment strategies affect the
    Trust's performance during the six-month period ended September 30, 2013?

A   The changing market environment hindered the Trust's performance during the
    six-month period, despite the facts that the Fed eventually decided not to
    taper QE, and that the Trust's portfolio held no bonds issued by the City of
    Detroit. The Trust's portfolio also had only minimal exposure to the
    Commonwealth of Puerto Rico, holding one small position in AA-rated senior
    debt backed by sales tax revenues. In a declining market, the Trust's use of
    leverage also hurt performance relative to the two Barclays benchmarks, as
    portfolio bond holdings purchased with leverage also declined in price
    during the six-month period. At the same time, the Trust experienced
    disappointing results from specific portfolio holdings in the
    underperforming tobacco bond group (which are backed by revenues from
    tobacco liability cases), and in the hospital/health care industry. The
    disappointing results came despite our investment discipline, which
    emphasizes purchasing only those investments that are backed by
    project-specific revenue sources, which are less vulnerable to factors such
    as the financial health of issuing agencies or municipalities. Several
    portfolio positions in longer-maturity, investment-grade municipal bonds
    also declined in price during the period due to the general rise in market
    interest rates.

    During the six-month period, the Trust's portfolio experienced no defaults,
    and shares of the Trust continued to sell at a premium price to net asset
    value.

Q   How did the level of leverage employed by the Trust change during the
    six-month period ended September 30, 2013?

A   At the end of the six-month period on September 30, 2013, 34.8% of the
    Trust's total managed assets were financed by leverage, compared with 32.1%
    of the Trust's total managed assets financed by leverage at the start of the
    period on April 1, 2013. The increase was due to a decrease in the value of
    securities in which the Trust had invested.

   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13 5


Q   What is your investment outlook?

A   After one of the more severe corrections in the municipal market in recent
    history, we believe the resulting lower prices of municipal bonds represent
    a significant opportunity for investors. The investment fundamentals of
    municipal debt securities remain strong, and prices are at extremely
    attractive levels, especially when compared with the taxable bond market.

    We believe the low prices to which municipal bonds have fallen are
    inconsistent with the underlying fundamentals of the asset class. The market
    continues to have very low default rates, and state revenues generally are
    improving. Further, municipal bonds currently are paying high tax-
    equivalent yields that should make them more attractive than other segments
    of the fixed-income market. We believe that the entire municipal market
    ($3.7 trillion in debt outstanding) is large enough to absorb problems
    experienced by any individual community or agency. In fact, the financial
    problems of the City of Detroit and the Commonwealth of Puerto Rico were
    well known before the six-month period began, and should have come as no
    surprise to informed investors. We believe the credit quality of the sector
    is further enhanced because two-thirds of the market consists of revenue
    bonds, which are secured by income-producing facilities of the borrower and
    are not dependent upon tax revenue generated by municipalities.

    Going forward, we intend to keep the Trust's portfolio concentrated almost
    exclusively in revenue bonds, and to maintain our focus on intensive,
    independent research into the credit-worthiness of individual securities as
    well as the issuing agencies or municipalities behind them.

    We believe the Trust is very well positioned for solid performance as market
    sentiment changes and investors again begin to focus on the underlying
    fundamentals and competitive prices of municipal bonds.

Please refer to the Schedule of Investments on pages 11-22 for a full listing of
Trust securities.

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 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.

By concentrating in municipal securities, the portfolio 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 currently uses leverage through the issuance of preferred shares.
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. 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 documents relating to its common shares and 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.

Any information in this shareowner report regarding market or economic trends or
the factors influencing the Trust's historical or future performance are
statements of opinion as of the date of this report. These statements should not
be relied upon for any other purposes.

Call 1-800-225-6292 or visit us.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 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 per common share 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.

Index comparison begins October 31, 2003. The Barclays Municipal Bond Index is
an unmanaged, broad measure of the municipal bond market. The Barclays High
Yield Municipal Bond Index is unmanaged, 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, issue date later than 12/31/90,
deal size over $20 million, 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. You cannot invest directly in the indices.

Notes to Financial Statements | 9/30/13 (unaudited)

1. Organization and Significant Accounting Policies

Pioneer Municipal High Income Advantage Trust (the Trust) was organized as a
Delaware statutory trust on August 6, 2003. Prior to commencing operations on
October 20, 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. Shares of
    money market mutual funds are valued at such funds' net asset value.

    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 by or at the
    direction or with the

28 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13


    approval of the Valuation Committee using fair value methods pursuant to
    procedures adopted by the Board of Trustees. The Valuation Committee is
    comprised of certain members of 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 significantly from
    exchange prices and such differences could be material. Pioneer Investment
    Management, Inc. (PIM), the Trust's investment adviser, is responsible for
    monitoring developments that may impact fair valued securities and for
    discussing and assessing fair values on an ongoing basis, and at least
    quarterly, with the Valuation Committee.

    At September 30, 2013, one security was valued using fair value methods
    (other than 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 interest or 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. As of
    September 30, 2013, the Trust did not have any interest and penalties
    related to uncertain tax positions, which if applicable, would be recorded
    as an income tax expense in the Statement of Operations. Tax years for the
    prior three fiscal years remain subject to examination by federal and state
    tax authorities.

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13 29


    The amount and character of income and capital gain distributions to
    shareowners are determined in accordance with federal income tax rules,
    which may differ from U.S. generally accepted accounting principles.
    Distributions in excess of net investment income or net realized gains are
    temporary overdistributions for financial statement purposes resulting from
    differences in the recognition or classification of income or distributions
    for financial statement and tax purposes. Capital accounts within the
    financial statements are adjusted for permanent book/tax differences to
    reflect tax character, but are not adjusted for temporary differences.

    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 March
    31, 2013 was as follows:

    Post-October loss deferred                                       (2,049,542)
    Dividends payable                                                    (5,961)
    Unrealized appreciation                                          38,273,825

         Total                                                    $ (15,418,219)
    ============================================================================
    

    The difference between book-basis and tax-basis unrealized appreciation is
    primarily attributable to the difference between book and tax amortization
    methods for premiums and discounts on fixed income securities, the
    difference between book and tax accounting for swap agreements, book/tax
    difference in accrual of income on securities in default, 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

30 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13


    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.

    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.

    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

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 period
ended September 30, 2013, the net management fee was 0.60% of the Trust's
average daily managed assets, which was equivalent to 0.90% 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 September 30,
2013, $276,404 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.

32 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13


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 September 30, 2013, 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 event of
non-performance

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13 33


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
September 30, 2013 or outstanding at September 30, 2013.

6. Trust Shares

There are an unlimited number of common shares of beneficial interest
authorized.

Transactions in common shares of beneficial interest for the periods ended
September 30, 2013 and March 31, 2013 were as follows:



--------------------------------------------------------------------------------
                                                        9/30/13          3/31/13
--------------------------------------------------------------------------------
                                                                
Shares outstanding at beginning of period            23,406,918       23,282,302
Reinvestment of distributions                            67,356          124,616
--------------------------------------------------------------------------------
Shares outstanding at end of period                  23,474,274       23,406,918
================================================================================


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
September 30, 2013, there were 6,000 APS as follows: Series A -- 3,000 and
Series B -- 3,000.

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 125% of the 7 day commercial paper rate or adjusted Kenny rate.
Dividend rates on APS ranged from 0.94% to 0.429% during the six months ended
September 30, 2013.

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,

34 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/13


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 October 4, 2013 a dividend from
undistributed net investment income of $0.0950 per common share payable October
31, 2013, to common shareowners of record on October 17, 2013.

Subsequent to September 30, 2013, dividends declared and paid on preferred
shares totaled $30,769 in aggregate for the two outstanding preferred share
series through November 13, 2013.

 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.

under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on the evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.


(b) Disclose any change in the registrant's internal control over financial
reporting (as defined in Rule 30a-3(d) under the Act (17CFR 270.30a-3(d)) that
occured during the second fiscal quarter of the period covered by this report
that has materially affected, or is reasonably likely to materially affect,
the registrant's internal control over financial reporting.

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.
