   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 1


President's Letter

Robust, synchronized global economic growth and rising corporate profits have
continued to drive strong performance in both the credit and equity markets for
most of 2017. U.S. stocks, as measured by the Standard & Poor's 500 Index, have
returned 14.23% year-to-date through September 30, 2017. Fixed-income markets,
while not generating the same dazzling returns as equities, have held their own,
led by high-yield securities, which produced a year-to-date return of 7.05% in
the U.S., as measured by the Bank of America Merrill Lynch U.S. High Yield
Index. Meanwhile, the Bloomberg Barclays U.S. Aggregate Bond Index has returned
3.14% since the start of the calendar year.

Continued strong employment numbers and higher consumer confidence, together
with solid global economic growth and a depreciating U.S. dollar contributed to
better-than-expected U.S. gross domestic product (GDP) growth of 3.1% in the
second quarter. Outside the U.S., economic growth in the second quarter also
surprised to the upside across the Euro zone, China, and Japan. Meanwhile,
despite higher oil and commodities prices, inflation continued to be moderate,
both in the U.S. and globally, enabling major non-U.S. central banks to maintain
their easy monetary policies. As expected, however, the U.S. Federal Reserve
System (the Fed) recently announced that it would commence tapering its balance
sheet this October. The Fed also appears primed to raise interest rates one more
time before the end of this year, which would be the fourth rate increase since
December of 2016.

As we move into the final months of 2017, we believe the U.S. economy will
experience modest growth in the short term, depending on the mix of economic
policies enacted as the country moves away from monetary stimulus (driven by the
Fed) and toward fiscal stimulus (potentially including tax reform) as well as
lighter regulatory burdens. Meanwhile, corporate earnings remain solid and we
think they will improve even further, despite some pressure from wage increases.
In addition, as the economy continues to grow and we begin to see a modest
upturn in inflation, we believe the Fed will continue to raise interest rates.

While economic and market conditions appear solid, there are always risks to
consider that could dampen the outlook. Geopolitical concerns, such as increased
tensions with North Korea, and continued political gridlock in Washington are
just some of the risks that could lead to increased market volatility.

Portfolio Management Discussion | 9/30/17

The municipal bond market generated positive results over the six-month period
ended September 30, 2017, with high-yield municipals slightly outperforming
investment-grade municipals. 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,
Director of Municipals, U.S., a senior vice president, and a portfolio manager
at Amundi Pioneer Asset Management ("Amundi Pioneer"), and Mr. Chirunga, a vice
president and a portfolio manager at Amundi Pioneer, are responsible for the
day-to-day management of the Trust.

Q    How did Pioneer Municipal High Income Advantage Trust perform during the
     six-month period ended September 30, 2017?

A    Pioneer Municipal High Income Advantage Trust returned 3.20% at net asset
     value (NAV) and 7.82% at market price during the six-month period ended
     September 30, 2017. During the same six-month period, the Trust's
     benchmarks, the Bloomberg Barclays U.S. Municipal High Yield Bond Index and
     the Bloomberg Barclays Municipal Bond Index, returned 3.52% and 3.04% at
     NAV, respectively. The Bloomberg Barclays U.S. Municipal High Yield Bond
     Index is an unmanaged measure of the performance of lower-rated municipal
     bonds, while the Bloomberg Barclays Municipal Bond Index is an unmanaged
     measure of the performance of investment-grade municipal bonds. Unlike the
     Trust, the two 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 6.78%, and the
     average return at NAV of the 11 closed-end funds in the same Lipper
     category was 4.48%.

     The shares of the Trust were selling at a 3.19% discount to NAV on
     September 30, 2017. Comparatively the shares of the Trust were selling at a
     7.34% discount to NAV on March 31, 2017.

     On September 30, 2017, the standardized 30-day SEC yield of the Trust's
     shares was 4.02%*.

*    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.

Q    How would you describe the investment environment in the municipal bond
     market during the six-month period ended September 30, 2017?

A    A favorable backdrop supported the tax-advantaged, municipal bond market
     over the six-month period, as both economic fundamentals and technical
     market factors helped municipal debt turn in positive performance.
     Favorable fundamentals included a persistently growing economy with
     improving corporate profits, low inflation, declines in market interest
     rates, and a U.S. Federal Reserve System (the Fed) that acted with
     restraint in gradually tightening monetary policy. Over the period, the Fed
     raised the Federal Funds rate just once, in June 2017, after enacting two
     rate hikes in the prior six months.

     Yields of longer-term debt, including U.S. Treasuries, moved lower during
     the period. From a technical perspective, the supply of new municipal bond
     issues in the market remained relatively low over the six months.
     Meanwhile, demand remained solid, including demand from non-traditional
     buyers of municipals, such as pension funds and foreign investors attracted
     by the relative value of municipals compared to bonds in the taxable
     market.

     In that environment, both investment-grade and high-yield municipals fared
     well, even in the face of some mild market volatility related to
     uncertainties regarding the direction of the U.S. government's fiscal
     policy. Some key initiatives, such as tax reform, remain under discussion,
     but have not yet become law.

     High-yield municipal bonds slightly outperformed investment-grade
     municipals during the period, even though the market for higher-yielding
     municipals retreated somewhat after the Commonwealth of Puerto Rico's June
     1, 2017, default on payments on a group of sales-tax-backed municipal
     bonds. That event, combined with the extensive damage the island suffered
     after Hurricane Maria made landfall in September, raised concerns about the
     Commonwealth's ability to meet its debt obligations. Before those events,
     Puerto Rico-issued bonds had a relatively high weighting in the Bloomberg
     Barclays High Yield Municipal Bond Index, accounting for about 13% of the
     index's asset value. The benchmark's Puerto Rico allocation had dropped
     significantly, from 13% to 4%, by the end of the six-month period as more
     defaulted bonds were removed from the Index.

   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 5


Q    What factors affected the Trust's performance relative to the Bloomberg
     Barclays municipal bond indices during the six-month period ended September
     30, 2017?

A    We maintained a well-diversified** portfolio during the period, with
     exposures to both investment-grade and high-yield municipal bonds. The
     diversification helped the Trust outperform the Bloomberg Barclays
     Municipal Bond Index, which tracks investment-grade municipals, even as it
     slightly trailed the return of the Bloomberg Barclays U.S. Municipal High
     Yield Bond Index. The Trust's exposure to longer-maturity investment-grade
     municipals, which performed particularly well as market interest rates
     declined, was a key positive contributor to benchmark-relative results.

     The portfolio's holdings of certain tobacco bonds funded by Master
     Settlement Agreements between the tobacco industry and individual states,
     and bonds issued by charter schools, also contributed to the Trust's
     benchmark-relative performance during the period.

     On the negative side, there were some holdings in the Trust's portfolio
     that underperformed during the period, such as bonds issued by Sanger
     (Texas) Industrial Development Corporation, which experienced ongoing
     credit problems that contributed to a moderate decrease in value, and by
     the Commonwealth of Puerto Rico, a general obligation bond with an 8.00%
     coupon, the Trust's only exposure to Puerto Rico's debt.

Q    Did the Trust's distributions to shareholders change during the six-month
     period ended September 30, 2017?

A    Yes, the Trust's distributions increased slightly over the six-month
     period.

Q    Did the level of leverage in the Trust change during the six-month period
     ended September 30, 2017?

A    At the end of the six-month period on September 30, 2017, 34.5% of the
     Trust's total managed assets were financed by leverage obtained through the
     issuance of preferred shares, compared with 34.6% of the Trust's total
     managed assets financed by leverage at the start of the period on April 1,
     2017. While the amount of funds borrowed by the Trust decreased slightly,
     the decrease in leverage as a percentage of total managed assets was
     primarily due to the appreciation in values of securities in which the
     Trust had invested.

6 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17


Q    Did the Trust invest in any derivative securities during the six-month
     period ended September 30, 2017?

A    No, the Trust's portfolio held no derivative securities during the period.

Q    What is your investment outlook?

A    We maintain an optimistic view of the municipal bond market, as its
     underlying fundamentals remain strong and investor demand remains high.
     Meanwhile, new supply is limited.

     The expectation is that the Fed will move carefully as it considers whether
     to tighten monetary policy further by raising the Federal Funds rate again,
     though a December 2017 rate increase remains a solid possibility. The Fed
     also recently announced that it would begin to reduce its balance sheet by
     limiting reinvestments in some of the holdings it purchased during its
     multiple quantitative-easing programs between 2008 and 2014.

     We anticipate that the U.S. economy will continue to expand at a moderate
     pace, and that corporate profits should continue to improve, which may
     benefit some of the portfolio's underlying credits. The most recent reports
     on growth in U.S. gross domestic product (GDP) showed that the economy grew
     at a 3.1% annual rate in the second quarter of 2017, while corporate
     earnings in the first quarter were 14.9% higher than a year earlier.
     Inflationary pressures have remained low, despite recent gains in
     employment. Thus far, policy gridlock in Congress has not caused much, if
     any market distress, and investors remain hopeful that lawmakers and
     President Trump can reach agreement on a tax reform/tax cut program that
     could stimulate economic growth.

     At this point, the full extent of hurricane damage in Puerto Rico remains
     unknown, but the Trust has very little exposure to Puerto Rico-issued debt.

     In managing the Trust going forward, we will continue to monitor events
     carefully and remain focused on intensive, fundamental research while
     maintaining a well-diversified portfolio, with exposures to both
     investment-grade and high-yield municipal securities.

   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 7


Please refer to the Schedule of Investments on pages 13-23 for a full listing of
Trust securities.

All investments are subject to risk, including the possible loss of principal.
In the past several years, financial markets have experienced increased
volatility, depressed valuations, decreased liquidity and heightened
uncertainty. These conditions may continue, recur, worsen or spread.

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
incremental income or capital appreciation for investments purchased with the
proceeds of leverage 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 meet 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, which is
likely to result in a decrease in the market value of the Trust's shares.

Call 1-800-225-6292 or visit www.amundipioneer.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.

Shares of 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 bought and 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 include 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 through open-market purchases 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.
Had these fees and taxes been reflected, performance would have been lower.

The Bloomberg Barclays Municipal Bond Index is an unmanaged, broad measure of
the municipal bond market. The Bloomberg Barclays U.S. Municipal High Yield Bond
Index is unmanaged, totals over $26 billion in market value and maintains over
1,300 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.

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.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Trust's investment
adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer
Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned
subsidiary of UniCredit S.p.A.

In connection with the transaction, the names of the Trust's investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management,
Inc. (the Adviser) and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the Distributor).

In October 2016, the Securities and Exchange Commission (SEC) released its
Final Rule on Investment Company Reporting Modernization. In addition to
introducing two new regulatory reporting forms (Form N-PORT and Form
N-CEN), the Final Rule amends Regulation S-X, which impacts financial
statement presentation, particularly related to the presentation of derivative
investments. The Fund's financial statements were prepared in compliance with
the amendments to Regulation S-X.

The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles (U.S. GAAP) that require the management
of the Trust to 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 period. Actual
results could differ from those estimates.

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 29


The Trust is an investment company and follows investment company
accounting and reporting guidance under U.S. GAAP. The following is a
summary of significant accounting policies followed by the Trust in the
preparation of its financial statements:

A.   Security Valuation

     The net asset value of the Trust is computed once daily, on each day the
     New York Stock Exchange (NYSE) is open, as of the close of regular trading
     on the NYSE.

     Fixed-income securities are valued by using 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, or may use a pricing matrix or other fair value
     methods or techniques to provide an estimated value of the security or
     instrument. A pricing matrix is a means of valuing a debt security on the
     basis of current market prices for other debt securities, historical
     trading patterns in the market for fixed-income securities and/or other
     factors. Non-U.S. debt securities that are listed on an exchange will be
     valued at the bid price obtained from an independent third party pricing
     service. When independent third party pricing services are unable to supply
     prices, or when prices or market quotations are considered to be
     unreliable, the value of that security may be determined using quotations
     from one or more broker-dealers.

     Shares of open-end registered investment companies (including money market
     mutual funds) are valued at such Trust's net asset value. Repurchase
     agreements are valued at par. Cash may include overnight time deposits at
     approved financial institutions.

     Securities for which independent pricing services or broker-dealers 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 a
     fair valuation team comprised of certain personnel of the Adviser, pursuant
     to procedures adopted by the Trust's Board of Trustees. The Adviser's fair
     valuation team uses fair value methods approved by the Valuation Committee
     of the Board of Trustees. The Adviser's fair valuation team 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 of the Board of Trustees.

     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. 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

30 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17


     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.

     At September 30, 2017, one security was valued using fair value methods (in
     addition to securities valued using prices supplied by independent pricing
     services, broker-dealers or using third party insurance pricing model)
     representing 1.2% of net assets. The value of this fair valued security is
     $3,306,000.

B.   Investment Income and Transactions

     Interest income, including interest on income-bearing cash accounts, is
     recorded on the accrual basis, net of unrecoverable foreign taxes withheld
     at the applicable country rates and net of income accrued on defaulted
     securities.

     Discounts and premiums on purchase prices of debt securities are accreted
     or amortized, respectively, daily, into interest income on an effective
     yield to maturity basis with a corresponding increase or decrease in the
     cost basis of the security. Premiums and discounts related to certain
     mortgage-backed securities are amortized or accreted in proportion to the
     monthly paydowns. Interest income payable by delivery of additional shares
     is reclassified as PIK (payment-in-kind) income upon receipt and is
     included in interest income.

     Security transactions are recorded as of trade date. Gains and losses on
     sales of investments are calculated on the identified cost method for both
     financial reporting and federal income tax purposes.

C.   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 net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no federal income tax provision is required. As
     of March 31, 2017, the Trust did not accrue any interest or penalties with
     respect to uncertain tax positions, which if applicable, would be recorded
     as an income tax expense in the Statement of Operations. Tax returns filed
     within the prior three years remain subject to examination by federal and
     state tax authorities.

     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. GAAP. Distributions in excess of net investment
     income or net realized gains are temporary overdistributions 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.

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 31


     The tax character of current year distributions payable to shareowners will
     be determined at the end of the current taxable year. The tax character of
     distributions paid to shareowners during the year ended March 31, 2017 was
     as follows:



     ---------------------------------------------------------------------------
                                                                            2017
     ---------------------------------------------------------------------------
                                                                  
     Distributions paid from:
     Tax exempt income                                               $18,477,950
     Ordinary income                                                     621,291
     ---------------------------------------------------------------------------
          Total                                                      $19,099,241
     ===========================================================================


     The following shows the components of distributable earnings (losses) on a
     federal income tax basis at March 31, 2017:



     ---------------------------------------------------------------------------
                                                                           2017
     ---------------------------------------------------------------------------
                                                                  
     Distributable earnings:
     Undistributed ordinary income                                 $    224,502
     Capital loss carryforward                                      (41,662,439)
     Late year loss deferrals                                          (599,676)
     Other book/tax temporary differences                             6,782,955
     Tax-exempt spillback                                             2,230,226
     Unrealized appreciation                                          9,953,268
     ---------------------------------------------------------------------------
          Total                                                    $(23,071,164)
     ===========================================================================


     The difference between book-basis and tax-basis unrealized appreciation/
     depreciation is primarily attributable to the realization for tax purposes
     of unrealized gains on investments in passive foreign investment companies,
     the book/tax differences in the accrual of income on securities in default,
     the difference between book and tax amortization methods and discounts on
     fixed income securities.

D.   Automatic Dividend Reinvestment Plan

     All 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 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.

32 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17


     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 shares of the
     Trust on terms that differ from the terms of the Plan.

     Whenever the Trust declares a dividend on shares payable in cash,
     participants in the Plan will receive the equivalent in shares acquired by
     the Plan Agent either (i) through receipt of additional unissued but
     authorized shares from the Trust or (ii) by purchase of outstanding shares
     on the New York Stock Exchange or elsewhere. If, on the payment date for
     any dividend, the net asset value per 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
     shares. The number of newly issued shares to be credited to each account
     will be determined by dividing the dollar amount of the dividend by the net
     asset value per 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 share is greater than the market value (market
     discount), the Plan Agent will invest the dividend amount in shares
     acquired in open-market purchases. There are no brokerage charges with
     respect to newly issued 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 be able to transfer the shares to another broker and
     continue to participate in the Plan.

E.   Risks

     The value of securities held by the Trust may go up or down, sometimes
     rapidly or unpredictably, due to general market conditions, such as real or
     perceived adverse economic, political or regulatory conditions, inflation,
     changes in interest rates, lack of liquidity in the bond markets or adverse
     investor sentiment. In the past several years, financial markets have
     experienced increased volatility, depressed valuations, decreased liquidity
     and heightened uncertainty. These conditions may continue, recur, worsen or
     spread.

     Interest rates in the U.S. recently have been historically low, so the
     Trust faces a heightened risk that interest rates may rise. A general rise
     in interest rates may cause investors to move out of fixed income
     securities on a large scale, which could adversely affect the price and
     liquidity of fixed income securities.

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 33


     The municipal bond market can be susceptible to unusual volatility,
     particularly for lower-rated and unrated securities. Liquidity can be
     reduced unpredictably in response to overall economic conditions or credit
     tightening. Municipal issuers may be adversely affected by rising health
     care costs, increasing unfunded pension liabilities, and by the phasing out
     of federal programs providing financial support. Unfavorable conditions and
     developments relating to projects financed with municipal securities can
     result in lower revenues to issuers of municipal securities, potentially
     resulting in defaults. Issuers often depend on revenues from these projects
     to make principal and interest payments. The value of municipal securities
     can also be adversely affected by changes in the financial condition of one
     or more individual municipal issuers or insurers of municipal issuers,
     regulatory and political developments, tax law changes or other legislative
     actions, and by uncertainties and public perceptions concerning these and
     other factors. Municipal securities may be more susceptible to down-grades
     or defaults during recessions or similar periods of economic stress. In
     recent periods, an increasing number of municipal issuers in the United
     States have defaulted on obligations and commenced insolvency proceedings.
     Financial difficulties of municipal issuers may continue or get worse. To
     the extent the Trust invests significantly in a single state, including
     California, Pennsylvania and Texas, or in securities the payments on which
     are dependent upon a single project or source of revenues, or that relate
     to a sector or industry, including health care facilities, education,
     transportation, special revenues and pollution control, the Trust will be
     more susceptible to associated risks and developments.

2. Management Agreement

The Adviser, manages the Trust's portfolio. Management fees payable under the
Trust's Advisory Agreement with the Adviser 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 or 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 September 30,
2017, the net management fee was 0.60% (annualized) of the Trust's average daily
managed assets, which was equivalent to 0.91% (annualized) of the Trust's
average daily net assets.

34 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17


In addition, under the Adviser management and administration agreements, certain
other services and costs are paid by the Adviser. At September 30, 2017,
$114,065, was payable to the Adviser related to management costs, administrative
costs and certain other services is included in "Due to affiliates" and
"Administration fee" on the Statement of Assets and Liabilities.

3. Transfer Agent

American Stock Transfer & Trust Company (AST) serves as the transfer agent with
respect to the Trust's common shares. The Trust pays AST an annual fee, as is
agreed to from time to time by the Trust and AST, for providing such services.

In addition, the Trust reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareowner communications activities
such as proxy and statement mailings and outgoing calls.

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.

4. 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
September 30, 2017 and the year ended March 31, 2017 were as follows:



--------------------------------------------------------------------------------
                                                          9/30/17        3/31/17
--------------------------------------------------------------------------------
                                                                
 Shares outstanding at beginning of period             23,899,020     23,822,909
 Reinvestment of distributions                                  --        76,111
--------------------------------------------------------------------------------
 Shares outstanding at end of period                   23,899,020     23,899,020
================================================================================


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, 2017, 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

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 35


for each series is 125% of the 7 day commercial paper rate or adjusted Kenny
rate. Dividend rates on APS ranged from 0.0128% to 0.0189 % during the six
months ended September 30, 2017.

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,
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.

5. Subsequent Events

A monthly dividend was declared on October 4, 2017 from undistributed and
accumulated net investment income of $0.500 per common share payable October 31,
2017, to common shareowners of record on October 18, 2017.

Subsequent to September 30, 2017, dividends declared and paid on preferred
shares totaled $278,970 in aggregate for the two outstanding preferred share
series through November 8, 2017.

The Board of Trustees has approved the redemption of the Trust's outstanding APS
at the liquidation preference per share of each series of APS, together with
accrued and unpaid dividends, if any, as of the redemption date.

The redemption of the Trust's APS is subject to the successful negotiation of a
refinancing plan, the satisfaction of certain notice and regulatory
requirements, and the closing conditions of the new financing. Specific
information related to the redemption process and timeframes will be released by
the Trust separately.

ADDITIONAL INFORMATION

no changes in the persons who are primarily responsible for the day-to-day
management of the Trust's portfolio.

Notice is hereby given in accordance with Section 23(c) of the Investment

Change in Independent Registered Public Accounting Firm

Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the
Trust's investment adviser, was an indirect, wholly owned subsidiary of
UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of
its Pioneer Investments business, which includes the Adviser, to Amundi (the
"Transaction"). As a result of the Transaction, the Adviser became an indirect,
wholly-owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A.
Amundi is headquartered in Paris, France, and, as of September 30, 2016, had
more than $1.1 trillion in assets under management worldwide.

Deloitte & Touche LLP ("D&T"), the Trust's previous independent registered
public accounting firm, informed the Audit Committee and the Board that it would
no longer be independent with respect to the Trust upon the completion of the
Transaction as a result of certain services being provided to Amundi and Credit
Agricole, and, accordingly, that it intended to resign as the Trust's
independent registered public accounting firm upon the completion of the
Transaction. D&T's resignation was effective on July 3, 2017, when the
Transaction was completed.

During the periods as to which D&T has served as the Trust's independent
registered public accounting firm, including the Trust's two most recent fiscal
years preceding the fiscal year ended July 31, 2017, D&T's reports on the
Trust's financial statements have not contained an adverse opinion or disclaimer
of opinion and have not been qualified or modified as to uncertainty, audit
scope or accounting principles. Further, there have been no disagreements with
D&T on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which, if not resolved to the
satisfaction of D&T, would have caused D&T to make reference to the subject
matter of the disagreement in connection with its report on the

  Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17 37


financial statements. In addition, there have been no reportable events of the
kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities
Exchange Act of 1934.

Effective immediately following the completion of the Transaction on July 3,
2017, the Board, acting upon the recommendation of the Audit Committee, engaged
a new independent registered public accounting firm, Ernst & Young LLP ("EY").

Prior to its engagement, EY had advised the Trust's Audit Committee that EY had
identified the following matters, in each case relating to services rendered by
other member firms of Ernst & Young Global Limited, all of which are located
outside the United States, to UniCredit and certain of its subsidiaries during
the period commencing July 1, 2016, that it determined to be inconsistent with
the auditor independence rules set forth by the Securities and Exchange
Commission ("SEC"): (a) project management support services to UniCredit in the
Czech Republic, Germany, Italy, Serbia and Slovenia in relation to twenty-two
projects, that were determined to be inconsistent with Rule 2-01(c)(4)(vi) of
Regulation S-X (management functions); (b) two engagements for UniCredit in
Italy where fees were contingent/success based and that were determined to be
inconsistent with Rule 2-01(c)(5) of Regulation S-X (contingent fees); (c) four
engagements where legal and expert services were provided to UniCredit in the
Czech Republic and Germany, and twenty engagements where the legal advisory
services were provided to UniCredit in Austria, Czech Republic, Italy and
Poland, that were determined to be inconsistent with Rule 2-01(c)(4)(ix) and (x)
of Regulation S-X (legal and expert services); and (d) two engagements for
UniCredit in Italy involving assistance in the sale of certain assets, that were
determined to be inconsistent with Rule 2-01(c)(4)(viii) of Regulation S-X
(broker-dealer, investment advisor or investment banking services). None of the
foregoing services involved the Trust, any of the other funds in the Pioneer
Family of Funds or any other Pioneer entity sold by UniCredit in the
Transaction.

EY advised the Audit Committee that it had considered the matters described
above and had concluded that such matters would not impair EY's ability to
exercise objective and impartial judgment in connection with the audits of the
financial statements of the Trust under the SEC and Public Company Accounting
Oversight Board independence rules, and that a reasonable investor with
knowledge of all relevant facts and circumstances would reach the same
conclusion. Management and the Audit Committee considered these matters and
discussed the matters with EY and, based upon EY's description of the matters
and statements made by EY, Management and the Audit Committee believe that EY
will be capable of exercising objective and

38 Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/17


impartial judgment in connection with the audits of the financial statements of
the Trust, and Management further believes that a reasonable investor with
knowledge of all relevant facts and circumstances would reach the same
conclusion.

registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller, or persons performing similar functions, regardless of

the registrant has not adopted such a code of ethics, explain why it has not
done so.

registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must

 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.

principal financials officers, or persons performing similar functions,
regarding the effectiveness of the registrant's disclosure

that includes the disclosure required by this paragraph,
based on the evaluation of these controls and procedures required by Rule
30a-3(b) under the Act (17 CFR 270.30(a)-3(b) and Rules 13a-15(b) or 15d-15(b)
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

There were no significant changes in the

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.
