Pioneer Tax Advantaged Balanced Trust
--------------------------------------------------------------------------------
LETTER TO SHAREOWNERS 11/30/04
--------------------------------------------------------------------------------

Dear Shareowner,
--------------------------------------------------------------------------------
High energy prices and rising interest rates caused concern among investors
during the third quarter of 2004. As oil prices touched $50 per barrel for the
first time, many consumers, faced with high priced gasoline and anticipating a
winter of hefty heating bills, responded by holding back on spending. Consumers
account for the bulk of the nation's economic activity, and retail sales over
the summer were erratic. Beyond soaring energy costs, which have the effect of
a tax increase on individuals and businesses, the slack job creation data of
the last few months also undermined confidence in the economic outlook. The
markets in general fell during the third quarter. Continued unsettled
conditions in Iraq and the ever present specter of terrorism also weighed on
investors' minds. Overseas, global markets were fairly stable, after stumbling
earlier in the year.

But the fuzzy economic picture was good news for bond investors. Despite three
hikes in short-term interest rates, the first increases in four years, bond
prices rose and yields fell over the period. Longer-term Treasury securities
were the strongest performers, with corporate bonds, including high-yield
issues, also delivering favorable returns. Lower long-term rates were also
beneficial to the housing and mortgage industries. Behind the rally in bonds
lies investor skepticism about the strength and durability of the current
economic recovery. A slowing recovery leading to an easing of inflationary
pressures may convince the Federal Reserve Board to slow the pace of future
rate increases. Less inflation would also mean better real returns for bond
holders.

Pioneer believes that the economy will continue to expand in 2005, but at a
more measured tempo. After an extended period of cutting costs and bolstering
balance sheets, many corporations are financially stronger than they have been
in some time. And although short-term interest rates have risen, they are still
relatively low and do not appear to be a barrier for companies needing to
borrow for expansion. Equity valuations now appear better aligned with earnings
prospects than was the case a year ago, when prices ran ahead of profit
expectations. Therefore, steady but moderate expansion in corporate profits has
the potential to drive stock prices higher.

As always, thank you for your investment in Pioneer Municipal High Income
Trust.

Respectfully,

/s/ Osbert M. Hood

performance results. Current performance may be lower or higher than the
performance data quoted.

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

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

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

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

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

Index comparison begins January 31, 2004. The Lehman Brothers Municipal Bond
Index is a widely recognized, unmanaged measure of approximately 15,000
municipal bonds. Bonds in the Index have a minimum credit rating of BBB, were
part of at least a $50 million issuance made within the past five years and have
a maturity of at least two years. S&P 500 Index is an unmanaged measure of 500
widely held common stocks listed on the New York Stock Exchange and the
over-the-counter market. Index returns are calculated monthly, assume
reinvestment of dividends and, unlike Trust returns, do not reflect any fees,
expenses or sales charges. You cannot invest directly in the Index.

Pioneer Tax Advantaged Balanced Trust
--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 11/30/04
--------------------------------------------------------------------------------

The first annual report for Pioneer Tax Advantaged Balanced Trust covers the
period since the Trust's inception on January 28, 2004 through November 30,
2004. In the report, David Eurkus, portfolio manager for the Trust's
fixed-income portion, and Walter Hunnewell, Jr., portfolio manager for the
Trust's equity portion, discuss the investment process, strategy and outlook.

Q: How did the Trust perform during the period?

A: Since inception, Pioneer Tax Advantaged Balanced Trust returned 6.09% at net
   asset value and 11.26% at market price. As of November 30, 2004, the Trust
   was selling at a discount of market price to net asset value of 12.4%. The
   Trust's net asset value return reflects the expenses associated with the
   start-up costs of the Trust. From February 1, 2004, through November 30,
   2004, the Lehman Brothers Municipal Bond Index returned 2.63%, while the S&P
   500 Index returned 5.29%. The Trust's relatively strong performance occurred
   mostly during the second half of the reporting period when market interest
   rates declined and bond prices rose, and the stock market rebounded from its
   lows of 2004.

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

Q: What was the environment like during the period?

A: Early in the period, the strength of the economic rebound raised concerns
   that inflation and interest rates might move higher. In that environment,
   there was a significant sell-off in the bond market, which pushed bond prices
   down and yields up. Equity markets also declined, as investors worried that
   higher interest rates would erode corporate profits and, ultimately, have a
   negative impact on stock prices.

   As the fiscal year progressed, however, reports associated with the economy
   indicated that the rapid pace of growth had shifted to a slower but steady
   rate. Despite this slight softening in the economic expansion, the Federal
   Reserve tightened monetary policy, boosting the federal funds rate on four
   occasions, each time by 0.25%. (The federal funds rate is the rate banks
   charge each other for overnight loans.) The Fed's policy had relatively
   little effect on market interest rates, which trended down. The favorable

   interest-rate environment was positive for both the bond and stock markets.
   In the fixed-income area, bond prices rose; and in the equity market, stock
   prices went up.

Q: What were the principal strategies used in managing the Trust?

A: Municipal securities accounted for 52% of the Trust's assets at period-end.
   In the fixed-income portion of the Trust, we primarily emphasized
   high-quality, investment-grade bonds; however, we also took advantage of our
   ability to invest up to 15% of fixed-income assets in below investment-grade
   securities, which helped boost the Trust's income stream. At the end of the
   period, the credit quality breakdown of fixed-income assets was: AAA (23.8%);
   AA (17.3%); A (23.1%); BBB (21.9%); and BB and lower (13.9%).

   Fixed-income assets were mainly concentrated in insured bonds (22.6%) and
   revenue bonds (77.4%). With revenue bonds, interest and principal are derived
   from the particular asset the bond was issued to finance. For example, a bond
   issued to finance a utility would be paid from the fees the utility charges
   its customers. Only 1.2% of fixed-income assets were in general obligation
   bonds, which are backed by the taxing power of the municipality that issues
   them. In terms of industry exposure, fixed-income assets were invested in
   health care (28.9%), housing (1.0%), pollution control (1.4%), transportation
   (6.0%), water and sewer (5.1%), among others.

   During the period, short-term interest rates declined, but long-term rates
   remained relatively high. The historically low short-term rates enabled the
   Trust to borrow funds inexpensively to invest in additional long-term
   municipal bonds. This leveraging strategy helped augment the Trust's income.
   At the end of the fiscal period on November 30, 2004, about 32% of the
   fixed-income portion of the Trust was leveraged, giving a boost to
   performance. About 60% of the Trust's leverage has been hedged for five
   years.

   At period-end approximately 47% of the Trust's assets were invested in
   equities, with 27% in common stocks and 20% in preferred stocks. We sought
   companies with long-term records of dividend payouts in the highest yielding
   areas of the market, such as financials (40.6% of equity net assets) and
   utilities (28.5% of equity net assets). We also invested in
   telecommunications (6.4% of equity net assets), consumer staples (5.8% of
   equity net assets), materials (5.7% of equity net assets), health care (4.6%
   of equity


                                                                               5

   net assets) and energy (3.8% of equity net assets). The energy and utilities
   sectors were the strongest performing areas of the market, and the Trust's
   investments in Duke Energy and Southern were significant contributors to
   performance. The Trust's return was also enhanced by Bank of America, one of
   our largest common equity holdings, as well as positions in Lyondell Chemical
   and Eastman Chemical, which paid attractive dividends and were well
   positioned to take advantage of the improving economy. The Trust's tobacco
   holdings posted impressive returns; however, to manage risk only 2.3% of net
   assets were invested in tobacco over the period.

Q: What detracted from performance?

A: In the first few months of the period, performance was held back when bond
   prices declined and yields rose because investors were concerned about the
   prospects for higher inflation and rising interest rates. Later on, however,
   when it became clear that the economic expansion would proceed at a moderate
   pace and interest rates would remain relatively low, bond prices rose,
   benefiting the Trust's return.

   On the equity side, our investments in the pharmaceutical industry (2.1% of
   net assets) detracted from results. We had a position in Merck that lost
   value when it removed from the market its COX-II pain relief drug Vioxx. We
   took advantage of the downturn in Merck's stock price to add to our position
   in the company. In our opinion, Merck remains a solid pharmaceutical company
   with the potential to maintain its record of consistent dividend payouts.

Q: What is your outlook over the next several months?

A: As we look ahead to 2005, we expect the current economic backdrop of moderate
   growth and relatively low interest rates to continue. We believe this type of
   environment should be positive for the high quality municipal bonds in the
   portfolio. It should also be supportive of our equity investments, which
   emphasize well established companies that continue to benefit from improving
   business prospects.

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

NOTES TO FINANCIAL STATEMENTS 11/30/04
--------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Tax Advantaged Balanced Trust (the "Trust") was organized as a Delaware
business trust on October 16, 2003. Prior to commencing operations on January
28, 2004, the Trust had no operations other than matters relating to its
organization and registration as a diversified, closed-end management
investment company under the Investment Company Act of 1940, as amended, and
the sale and issuance to Pioneer Funds Distributor, Inc., an affiliate of
Pioneer Investment Management, Inc. ("PIM"), the Trust's investment adviser, a
wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito
Italiano), of 6,981 shares of beneficial interest at an aggregate purchase
price of $100,003. PIM has paid all the Trust's organizational expenses. The
investment objective of the Trust is to provide a high level of total after-tax
return, including attractive tax-advantaged income.

The Trust may invest in municipal securities with a broad range of maturities
and credit ratings, including both investment grade and below investment grade
municipal securities. The Trust may also invest in common stocks and preferred
securities that pay tax-qualified dividends. In addition, the Trust may invest
in other securities, including debt instruments, real estate investment trusts
("REITS") and equity securities, that generate income taxable at ordinary
income rates, rather than long-term capital gain rates.

The Trust invests in below investment grade (high yield) debt securities. Debt
securities rated below investment grade are commonly referred to as "'junk
bonds'" and are considered speculative. These securities involve greater risk
of loss, are subject to greater price volatility, and are less liquid,
especially during periods of economic uncertainty or change, than higher rated
debt securities.

The Trust's financial statements have been prepared in conformity with U.S.
accounting principles generally accepted in the United States of America that
require the management of the Trust to, among other things, make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of income, expenses and gains and losses
on investments during the reporting period. Actual results could differ from
those estimates. The following is a summary of significant


                                                                              25

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 11/30/04                               (continued)
--------------------------------------------------------------------------------

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

A. Security Valuation

   Security transactions are recorded as of trade date. Debt securities are
   valued at prices supplied by independent pricing services, which consider
   such factors as Treasury spreads, yields, maturities and ratings. Valuations
   may be supplemented by dealers and other sources, as required. Equity
   securities are valued at the last sale price on the principal exchange where
   they are traded. The value of interest rate swaps are determined by obtaining
   dealer quotations. Securities for which market quotations are not readily
   available are valued at their fair values as determined by, or under the
   direction of, the Board of Trustees. The Trust may also use the fair value of
   a security, including a non U.S. security, when the closing market price on
   the principal exchange where the security is traded no longer accurately
   reflects the value of the security as of the close of the exchange. As of
   November 30, 2004, the Trust had no fair valued securities.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Trust becomes aware of the ex-dividend data in
   the exercise of reasonable diligence. Discount and premium on debt securities
   are accreted or amortized daily, respectively, on an effective yield to
   maturity basis and are included in interest income. Interest income,
   including income on interest bearing cash accounts, is recorded on an accrual
   basis. Temporary cash investments are valued at amortized cost.

   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.


26


Pioneer Tax Advantaged Balanced Trust
--------------------------------------------------------------------------------

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

   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the source of the Trust's distributions may be shown in
   the accompanying financial statements as either from or in excess of net
   investment income or net realized gain on investment transactions, or from
   paid-in capital, depending on the type of book/tax differences that may
   exist.

   At November 30, 2004, the Trust reclassified $329,251 to decrease
   undistributed net investment income and to decrease accumulated net realized
   loss on investments. The reclassification has no impact on the net asset
   value of the Trust and presents the Trust's capital accounts on a tax basis.

   At November 30, 2004, the Trust had a capital loss carryforward of $6,830,525
   which will expire in 2012 if not utilized.

   The tax character of current year distributions paid to common and preferred
   shareowners during the period ended November 30, 2004 was as follows:

                                  2004

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

   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.

C. Automatic Dividend Reinvestment Plan

   All common shareowners automatically participate in the Automatic Dividend
   Reinvestment Plan (the "Plan"), under which participants receive all
   dividends and capital gain distributions (collectively, "dividends") in full
   and fractional common shares of the Trust in lieu of cash. Shareowners may
   elect not to participate in the Plan. Shareowners not participating in the
   Plan receive all dividends and capital gain distributions in cash.
   Participation in the Plan is completely voluntary and may be terminated or
   resumed at any time without penalty by notifying Mellon Investor Services
   LLC, the agent for shareowners in administering the Plan (the "Plan Agent"),
   in writing prior to any dividend record date; otherwise such termination or
   resumption will be effective with respect to any subsequently declared
   dividend or other distribution. Whenever the Trust declares a dividend on
   common shares payable in cash, participants in the Plan will receive the
   equivalent in common shares acquired by the Plan Agent either (i) through
   receipt of additional unissued but authorized common shares from the Trust or
   (ii) by purchase of outstanding common shares on the New York Stock Exchange
   or elsewhere. If, on the payment date for any dividend, the net asset value
   per common share is equal to or less than the market price per share plus
   estimated brokerage trading fees ("market premium"), the Plan Agent will
   invest the dividend amount in newly issued common shares. The number of newly
   issued common shares to be credited to each account will be determined by
   dividing the dollar amount of the dividend by the net asset value per common
   share on the date the shares are issued, provided that the maximum discount
   from the then current market price per share on the date of issuance does not
   exceed 5%. If, on the payment date for any dividend, the net asset value per
   common share is greater than the market value ("market discount"), the Plan
   Agent will invest the dividend amount in common shares acquired in
   open-market purchases. There are no brokerage charges with respect to newly
   issued common shares. However, each participant will pay a pro rata share of
   brokerage trading fees incurred with


28


Pioneer Tax Advantaged Balanced Trust
--------------------------------------------------------------------------------

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

   respect to the Plan Agent's open-market purchases. Participating in the Plan
   does not relieve shareowners from any federal, state or local taxes which may
   be due on dividends paid in any taxable year. Shareowners holding Plan shares
   in a brokerage account may not be able to transfer the shares to another
   broker and continue to participate in the Plan.

2. Management Agreement

PIM manages the Trust's portfolio. Management fees are calculated daily at the
annual rate of 0.60% of the Trust's average daily managed assets. "Managed
assets" is the average daily value of the Trust's total assets minus the sum of
the Trust's liabilities, which liabilities exclude debt related to leverage,
short-term debt and the aggregate liquidation preference of any outstanding
preferred shares. At November 30, 2004, $292,664 was payable to PIM related to
management fees.

In addition, under PIM's management and administration agreements, certain
other services and costs are paid by the Trust. PIM has retained Princeton
Administrators, L.P., an affiliate of Merrill Lynch, Pierce, Fenner & Smith
Incorporated, to provide certain administrative services to the Trust on its
behalf. The Trust pays Princeton Administrators, L.P. a monthly fee at an
annual rate of 0.07% of the average daily value of the Trust's managed assets
up to $500 million and 0.03% for average daily managed assets in excess of $500
million, subject to a minimum monthly fee of $10,000.

Also, PIM has agreed for the first three years of the Trust's investment
operations to limit the Trust's total annual expenses [excluding offering costs
for common and preferred shares, interest expense, the cost of defending or
prosecuting any claim or litigation to which the Trust is a party (together
with any amount in judgment or settlement), indemnification expenses or taxes
incurred due to the failure of the Trust to qualify as a regulated investment
company under the Code or any other non-recurring or non-operating expenses] to
0.80% of the Trust's average daily managed assets. The dividend on any
preferred shares is not an expense. Under the agreement, PIM may subsequently
recover reimbursed expenses within three years of being incurred from the Trust
if the Trust's total expenses are less than 0.80% of average managed assets.
For the period ended, November 30, 2004, the Trust's expenses were not reduced
under such arrangements.


                                                                              29

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

3. Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly
owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency
agreement with Mellon Investor Services LLC, provides substantially all
transfer agent and shareowner services related to the Trust's common shares at
negotiated rates. Deutsche Bank Trust Company Americas is the transfer agent,
registrar, dividend paying agent and redemption agent with respect to the
Trust's Auction Market Preferred Shares ("AMPS"). The Trust pays Deutsche Bank
Trust Company Americas an annual fee, as is agreed to from time to time by the
Trust and Deutsche Bank Trust Company Americas, for providing such services.

4. 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 and exchange of net
interest payments between the parties. For financial reporting purposes, the
Trust records the net receivable or payable for the net interest expected to be
received or paid as net realized gains or losses from interest rate swaps in
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" to reflect the market value of the swap. 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) the closing contract
and the cost basis of the contract. The Trust is exposed to credit risk in the
event of non-performance by the other party to the interest rate swap. However,
the Trust does not anticipate non-performance by any counterparty.

There are an unlimited number of common shares of beneficial interest
authorized. Of the 28,706,981 common shares of beneficial interest outstanding
at November 30, 2004, PIM owned 6,981 shares.

Transactions in common shares of beneficial interest for the period January 28,
2004 (commencement of investment operations) to November 30, 2004 were as
follows:

                                                     ----------
Shares outstanding at end of period                  28,706,981
                                                     ----------
-------------------------------------------------------------------


Offering costs of $851,752 incurred in connection with the Trust's offering of
common shares have been charged to paid-in capital.

The Trust may classify or reclassify any unissued common shares of beneficial
interest into one or more series of preferred shares of beneficial interest. On
April 12, 2004, the Trust reclassified and issued 7,050 shares of common shares
into three series of Auction Market Preferred Shares ("AMPS") as follows: Series
T7 - 2,350, Series F7 - 2,350 and Series TH28 - 2,350. Offering costs of
$253,194 and underwriting discounts of $1,762,500 have been charged to paid-in
capital.

Dividends on Series T7 AMPS and Series F7 AMPS are cumulative at a rate which
is reset every seven days based on the results of an auction. Dividends on
Series TH28 AMPS are also cumulative at a


                                                                              31

rate reset every 28 days based on the results of an auction. Dividend rates
ranged from 1.05% to 2.09% during the period from April 12, 2004 to November
30, 2004.

The Trust may not declare dividends or make other distributions on its common
shares or purchase any such shares if, at the time of the declaration,
distribution or purchase, asset coverage with respect to the outstanding
preferred shares would be less than 200%.

The AMPS are redeemable at the option of the Trust, in whole or in part, on any
dividend payment date at $25,000 per share plus any accumulated or unpaid
dividends, whether or not declared. The AMPS are also subject to mandatory
redemption at $25,000 per share plus any accumulated or unpaid dividends,
whether or not declared, if certain requirements relating to the composition of
the assets and liabilities of the Trust as set forth in the Agreement and
Declaration of Trust are not satisfied.

The holders of AMPS have voting rights equal to the holders of the Trust's
common shares (one vote per share) and will vote together with holders of the
common shares as a single class. However, holders of AMPS are also entitled to
elect two of the Trust's Trustees. In addition, the Investment Company Act of
1940, as amended, requires that along with approval by shareowners that might
otherwise be required, the approval of the holders of a majority of any
outstanding preferred shares, voting separately as a class, would be required
to (a) adopt any plan of reorganization that would adversely affect the
preferred shares and (b) take any action requiring a vote of security holders,
including, among other things, changes in the Trust's subclassification as a
closed-end investment company or changes in its fundamental investment
restrictions.

6. Subsequent Events

Subsequent to November 30, 2004 the Board of Trustees of the Trust declared two
dividends from undistributed net investment income of $0.0687 per common share
one payable December 31, 2004 and one January 19, 2005 to common shareowners of
record on December 13, 2004 and December 31, 2004, respectively.

For the period December 1, 2004 to December 31, 2004, dividends declared on
preferred stock totaled $339,787 in aggregate for the three outstanding
preferred share series.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

To the Board of Trustees and Shareowners
of Pioneer Tax Advantaged Balanced Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Tax Advantaged Balanced Trust (the
"Trust") as of November 30, 2004, and the related statements of operations and
changes in net assets, and the financial highlights, for the period from
January 28, 2004 (commencement of operations) to November 30, 2004. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
November 30, 2004, by correspondence with the custodian and brokers or by other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Tax Advantaged Balanced Trust at November 30, 2004, the results of its
operations, the changes in its net assets, and the financial highlights for the
period from January 28, 2004 (commencement of operations) to November 30, 2004,
in conformity with U.S. generally accepted accounting principles.

                                                           /s/ Ernst & Young LLP

 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 recognizes 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 recognizes 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.

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

--------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

    N/A

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The Fund's independent auditor, Ernst & Young 
LLP ("E&Y"), recently has advised the Securities 
and Exchange Commission, the Public Company 
Accounting Oversight Board, and the Audit 
Committee of the Fund's Board of Trustees that 
certain non-audit work performed by E&Y's China 
affiliate has raised questions regarding E&Y's 
independence with respect to its performance of 
audit services for the Fund.  In July 2004, E&Y 
became aware that member firms in China ("E&Y 
China") provided certain tax services to offices of 
UniCredito Italiano, S.p.A. ("UCI"), a member of 
the Fund's Investment Company Complex.  The 
services included receipt and disbursement of 
monies transferred to E&Y China by UCI in 
payment of individual expatriate income taxes due 
on returns prepared by E&Y China for certain UCI 
employees located in China from October 1998 to 
May 2003.  E&Y became auditors of the Fund in 
May 2002.  These expatriate tax services were 
discontinued in May 2003.  The fees received by 
E&Y China for all such services totaled $3,685.

The Fund's Audit Committee and E&Y have 
discussed the matter, including the nature of the 
services provided, the personnel involved in 
providing the services and the fees received by 
E&Y for performing the services.  The Committee 
continues to review the facts and circumstances 
surrounding the matter, including the issue of 
whether the monies transferred for employees' taxes 
were de facto monies due the employees for tax 
payments rather than monies belonging to UCI.  
E&Y has informed the Audit Committee that based 
on its internal reviews and the de minimis nature of 
the services provided and fees received, it does not 
believe its independence with respect to the Fund 
has been impaired.

Aggregate Non-Audit Fees

The aggregate non-audit fees for the Trust and 
affiliates, as previously defined, totaled $19,000 in 
2004. 

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

Non-Audit Services
Beginning with non-audit service contracts entered 
into on or after May 6, 2003, the effective date of the 
new SEC pre-approval rules, the Trusts audit 
committee is required to pre-approve services to 
affiliates defined by SEC rules to the extent that the 
services are determined to have a direct impact on the 
operations or financial reporting of the Trust.  For the 
year ended November 30, 2004, there were no services 
provided to an affiliate that required the Trusts audit 
committee pre-approval.


The Trust's audit committee of the Board of Trustees 
has considered whether the provision of non-audit 
services that were rendered to the Affiliates (as 
defined) that were not pre-approved pursuant to 
paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is 
compatible with maintaining the principal accountant's 
independence.
