INTRODUCTION

This proxy statement is being used by the Board of Trustees of each fund
to solicit proxies to be voted at the annual meeting of shareholders of each of
the funds referenced above. Participating in the meeting are holders of common
shares of beneficial interest (the "Common Shares") and the holders of
preferred shares of beneficial interest (the "Preferred Shares") of each fund.
The Common Shares and the Preferred Shares of each fund sometimes are referred
to herein collectively as the "Shares". Each meeting will be held at the
offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, 26th
Floor, Boston, Massachusetts 02109, at 2:00 p.m., Boston time, on July 25,
2006, and at any adjournments of a meeting to a later date, for the purposes as
set forth in the accompanying notice of annual meeting of shareholders.

This proxy statement and the enclosed proxy card are being mailed to
shareholders of each fund on or about June 14, 2006. The annual report for each
fund for its most recently completed fiscal year was previously mailed to
shareholders.

WHO IS ELIGIBLE TO VOTE

Shareholders of record of each fund as of the close of business on June 2,
2006 (the "record date") are entitled to vote on all of the fund's business at
the annual shareholder meeting and any adjournments thereof. The affirmative
vote of a plurality of the Common and Preferred Shares of each fund present at
the meeting in person or by proxy, voting together as a single class, is
required to elect each nominee for Trustee designated to be elected by the
Common and Preferred Shares of each fund. The affirmative vote of a plurality
of the Preferred Shares of each fund present at the meeting in person or by
proxy is required to elect each nominee for Trustee designated to be elected by
the Preferred

Shares of each fund. Election by plurality means those persons who receive the
highest number of votes cast "FOR" up to the total number of persons to be
elected as Trustees at the meeting shall be elected. Shares represented by
properly executed proxies, unless revoked before or at the meeting, will be
voted according to the shareholder's instructions. If you sign a proxy but do
not fill in a vote, your shares will be voted in favor of each of the nominees
for Trustee. If any other business comes before the annual shareholder meeting,
your shares will be voted at the discretion of the persons named as proxies.

Each fund will vote separately on each item. Votes of multiple funds will
not be aggregated.

PROPOSAL 1

ELECTION OF BOARD OF TRUSTEES

Shareholders of each fund are being asked to consider the election of
three nominees to the Board of Trustees of each fund. All of the nominees for
election to each fund's Board currently serve as Trustees for the fund and have
served in that capacity continuously since originally elected or appointed.
Each Trustee shall be elected to hold office for a three year term or until his
or her successor is elected and qualified. Each nominee has consented to being
named in this proxy statement and indicated his or her willingness to serve if
elected. In the unanticipated event that any nominee should be unable to serve,
the persons named as proxies may vote for such other person as shall be
designated by the fund's Board of Trustees. The persons named on the
accompanying proxy card intend to vote at the meeting (unless otherwise
directed) for the election of the nominees named below as Trustees of each
fund.

The Declaration of Trust for each fund provides that the Board of Trustees
shall consist of Trustees divided into three classes, the classes to be as
nearly equal in number as possible. The Trustees of only one class are elected
at each annual meeting so that the regular term of only one class of Trustees
will expire annually and any particular Trustee stands for election only once
in each three year period. Each fund's Board of Trustees is divided into three
staggered term classes -- Class I, Class II and Class III. Class II Trustees
are being submitted to shareholders for election at the meeting for Pioneer Tax
Advantaged Balanced Trust. Class III Trustees are being submitted to
shareholders for election at the meeting for Pioneer Floating Rate Trust.

Each fund's Board of Trustees consists of nine members.

Pioneer Floating Rate Trust
The terms of the Class I Trustees -- Mr. Cogan, Mr. Bock and Mr. West
-- expire in 2007; the terms of the Class II Trustees -- Ms. Graham, Mr. Hood
and Mr. Winthrop -- expire in 2008; and the terms of the Class III Trustees
-- Ms. Bush, Mr. Perna and Ms. Piret -- expire at the upcoming 2006 annual
meeting.

Pioneer Tax Advantaged Balanced Trust

The terms of the Class I Trustees -- Ms. Graham, Mr. Hood and Mr.
Winthrop -- expire in 2008; the terms of the Class II Trustees -- Ms. Bush, Mr.
Perna and Ms. Piret -- expire at the upcoming 2006 annual meeting; and the
terms of the Class III Trustees -- Mr. Cogan, Mr. Bock and Mr. West -- expire
in 2007.

Subsequently, for each fund, each class of Trustees will stand for
election at the conclusion of its respective three year term. Such
classification may prevent replacement of a majority of the Trustees for up to
a two-year period. Mr. Cogan and Ms. Piret have been designated as the Trustees
to be elected by the holders of the Preferred Shares of each fund.

The following table sets forth the incumbent Trustees and each Trustee's
position(s) with each fund, his or her age, address, principal occupation and
employment during the past five years and any other directorship held. Trustees
who are interested persons of a fund within the meaning of the Investment
Company Act of 1940, as amended (the "1940 Act") are referred to as Interested
Trustees. Trustees who are not interested persons of a fund are referred to as
Independent Trustees. Each of the Trustees (except Mr. Hood and Mr. West)
serves as a Trustee of each of the 91 U.S. registered investment portfolios for
which Pioneer Investment Management, Inc. ("Pioneer") serves as investment
adviser (the "Pioneer Funds"). Mr. Hood and Mr. West each serves as Trustee of
35 of the 91 Pioneer Funds. The address of all Interested Trustees is 60 State
Street, Boston, Massachusetts 02109.

Board Committees
The Board of Trustees for each fund has an Audit Committee, an Independent
Trustees Committee, a Nominating Committee, a Valuation Committee and a Policy
Administration Committee. Committee members are as follows:

Audit
David R. Bock, Margaret B.W. Graham, Marguerite A. Piret (Chair) and
Stephen K. West

Independent Trustees
David R. Bock, Mary K. Bush, Margaret B.W. Graham (Chair), Thomas J.
Perna, Marguerite A. Piret, Stephen K. West and John Winthrop

Nominating
Mary K. Bush, Marguerite A. Piret and John Winthrop (Chair)

Valuation
David R. Bock, Margaret B.W. Graham and Marguerite A. Piret (Chair)

Policy Administration
Mary K. Bush (Chair), Thomas J. Perna and John Winthrop

During the most recent fiscal year, the Audit, Nominating, Valuation,
Independent Trustees and Policy Administration Committees of each fund held the
following meetings:

Tax Advantaged
Floating Rate Trust Balanced Trust
--------------------- ---------------

Audit Committee ......................... 18 18
Nominating Committee .................... 9 9
Valuation Committee ..................... 5 5
Independent Trustees .................... 16 16
Policy Administration Committee ......... 9 9

All members of the Audit Committee are "independent", as defined in the
applicable listing standard of the New York Stock Exchange currently in effect.
The Board of Trustees has adopted a charter for the Audit Committee, in effect
as of March 15, 2005. In accordance with its charter, the purposes of the Audit
Committee are to:

o act as a liaison between the fund's independent registered public
accounting firm and the full Board of Trustees of the fund;

o discuss with the fund's independent registered public accounting firm
their judgments about the quality of the fund's accounting principles and
underlying estimates as applied in the fund's financial reporting;

o review and assess the renewal materials of all related party contracts
and agreements, including management advisory agreements, underwriting
contracts, administration agreements, distribution contracts, and
transfer agency contracts, among any other instruments and agreements
that may be appropriate from time to time;

o review and approve insurance coverage and allocations of premiums
between the management and the fund and among the Pioneer Funds;

o review and approve expenses under the administration agreement between
Pioneer and the fund and allocations of such expenses among the Pioneer
Funds; and

o receive on a periodic basis a formal written statement delineating all
relationships between the independent registered public accounting firm
and the fund or Pioneer; to actively engage in a dialogue with the
independent registered public accounting firm with respect to any
disclosed relationships or services that may impact the objectivity and
independence of the independent registered public accounting firm; and to
recommend that the Trustees take appropriate action in response to the
independent registered public accounting firm's report to satisfy itself
of the firm's independence.

The Audit Committee reports that it has (1) reviewed and discussed each
fund's audited financial statements with management; (2) discussed with the
independent registered public accounting firm the matters relating to the
quality of each fund's financial reporting; and (3) received written
disclosures and an independence letter from the independent registered public
accounting firm and discussed with the independent registered public accounting
firm that firm's independence. Based upon the review and discussions referred
to above, the Audit Committee recommended to the Board of Trustees that the
audited financial statements be included in the Annual Reports for Pioneer
Floating Rate Trust and Pioneer Tax Advantaged Balanced Trust for the fiscal
year ended November 30, 2005, for filing with the Securities and Exchange
Commission (the "SEC").

Each fund's Board of Trustees has determined that each fund has at least
one audit committee financial expert. Ms. Marguerite A. Piret, an independent
trustee, is the audit committee's financial expert.

All members of the Nominating Committee are independent under the New York
Stock Exchange's Revised Listing Rules and are not interested persons, as
defined in the 1940 Act, of Pioneer. The Board of each fund has adopted a
written charter for the Nominating Committee, which is available on Pioneer's
website: www.pioneerfunds.com. The Nominating Committee reviews the
qualifications of persons being considered as candidates as Trustees and makes
recommendations regarding the qualifications of such persons to the Independent
Trustees. All of the Independent Trustees then evaluate any candidate and
determine whether to nominate them for election. The Trustees who are not
Independent Trustees and the officers of each fund are nominated and selected
by the Board.

The Nominating Committee's charter provides for certain criteria to be
used in evaluating candidates for Independent Trustee. In reviewing a potential
nominee and in evaluating the re-nomination of current Independent Trustees,
the Nominating Committee applies the following criteria: (i) the nominee's
reputation for integrity, honesty and adherence to high ethical standards, (ii)
the nominee's business acumen and ability to exercise sound judgments, (iii) a
commitment to attend and participate in meetings of the Board and its
committees, (iv) the ability to understand potential conflicts of interest in
managing a fund and to act in the interests of all shareholders, and (v) the
absence of a real or apparent conflict of interest that would impair the
nominee's ability to represent the interests of all the shareholders and to
fulfill the responsibilities of an Independent Trustee. The Nominating
Committee does not necessarily place the same emphasis on each criteria and
each nominee may not have each of these qualities.

As long as an existing Independent Trustee continues, in the opinion of
the other Independent Trustees, to satisfy these criteria and continues to make
positive contributions to the Board, each fund anticipates that Independent
Trustees of each fund would favor the re-nomination of an existing Trustee
rather than a new candidate. Consequently, while the Nominating Committee will
evaluate the qualifications of nominees recommended by shareholders to serve as
Trustee, the Independent Trustees may only act upon the Nominating Committee's
evaluation if there is a vacancy on the Board. In the event that a vacancy
arises or a change in Board membership is determined to be advisable, the
Nominating Committee will, in addition to any shareholder recommendations,
evaluate candidates identified by other means, including candidates proposed by
Independent Trustees or management. While it has not done so in the past, the
Nominating Committee may retain a consultant to assist the Committee in a
search for a qualified candidate.

Any shareholder recommendation must be submitted in compliance with all of
the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of
1934, as amended (the "Exchange Act") to be considered by the Nominating
Committee. In evaluating a nominee recommended by a shareholder, the Nominating
Committee, in addition to the criteria discussed above, may consider the
objectives of the shareholder in submitting that nomination and whether such
objectives are consistent with the interests of all shareholders. If the Board
determines to include a shareholder's candidate among the slate of nominees,
the candidate's name will be placed on the fund's proxy card. If the Nominating
Committee, the Independent Trustees or the Board determines not to include such
candidate among the Board's designated nominees and the shareholder has
satisfied the requirements of Rule 14a-8, the shareholder's candidate will be
treated as a nominee of the shareholder who originally nominated the candidate.

The Nominating Committee initiated the recommendation of each of the
nominees to serve as Independent Trustee.

Shareholders may communicate with the members of the Board as a group or
individually. Any such communication should be sent to the Board or an
individual Trustee c/o the Secretary of the fund at the address on the notice
of this meeting. The Secretary may determine not to forward any letter to
members of the Board that does not relate to the business of a fund.

The Valuation Committee reviews the valuation assigned to certain
securities by Pioneer in accordance with each fund's valuation procedures.

The Policy Administration Committee reviews the implementation of certain
of each fund's administrative policies and procedures.

The Independent Trustees Committee reviews each fund's management contract
and other related party contracts annually and is also responsible for any
other action required to be taken, under the 1940 Act, by the Independent
Trustees acting alone.

Each fund's Declaration of Trust provides that the fund will indemnify the
Trustees and officers against liabilities and expenses reasonably incurred in
connection with any litigation in which they may be involved because of their
offices with the fund, unless it is determined in the manner specified in the
Declaration of Trust that they have not acted in good faith in the reasonable
belief that their actions were in the best interests of the fund or that such
indemnification would relieve any officer or Trustee of any liability to the
fund or its shareholders by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of his or her duties.

During each fund's most recent fiscal year, the Board of Trustees held 14
meetings. All of the current Trustees and committee members of each fund then
serving attended at least 75% of the meetings of the Board of Trustees and
applicable committees, if any, held during that fund's fiscal year.

The following table indicates the value of shares that each Trustee or
nominee beneficially owned in each fund and Pioneer Funds in the aggregate as
of April 30, 2006. Beneficial ownership is determined in accordance with SEC
rules. The share value of any closed-end Pioneer fund is based on its closing
market price on April 30, 2006. The share value of any open-end Pioneer fund is
based on the net asset value of the class of shares on April 30, 2006. The
dollar ranges in this table are in accordance with SEC requirements.

Trustees and person who own more than ten percent of a fund's shares ("10%
Shareholders") to file reports of ownership and changes in ownership with the
SEC. Executive officers, Trustees and 10% Shareholders are required by SEC
regulations to furnish the fund with copies of all Section 16(a) forms they
file. Except as noted below, based solely on a review of the copies of these
reports furnished to each of the funds and representations that no other
reports were required to be filed, each fund believes that during the past
fiscal year its executive officers, Trustees and 10% Shareholders complied with
all applicable Section 16(a) filing requirements. Due to an error by each fund
and not the Trustee, Forms 3 for Mr. Bock and Mr. Perna were filed subsequent
to the required date for such filings. Forms 4, if any, showing changes in
ownership of each fund's securities by such Trustees were filed in a timely
manner.

Other executive officers
In addition to Mr. Cogan and Mr. Hood, who serve as President and
Executive Vice President, respectively, of each fund, the following table
provides information with respect to the other executive officers of the funds.
Each executive officer is elected by the Board of Trustees and serves until his
or her successor is chosen and qualified or until his or her resignation or
removal by the Board. The business address of all officers of the funds is 60
State Street, Boston, Massachusetts 02109.

Investment adviser and administrator
Pioneer, whose executive offices are located at 60 State Street, Boston,
Massachusetts 02109, serves as investment adviser and administrator to each
fund. Pioneer has retained Highland Capital Management, L.P. to act as
subadviser to Pioneer Floating Rate Trust.

The Trustees may, but generally do not, attend shareholder meetings. John
F. Cogan, Jr. attended the 2005 annual shareholder meeting.

Required vote
In accordance with each fund's agreement and declaration of trust, the
holders of Common Shares and Preferred Shares of each fund will vote on the
respective nominees designated to be elected by such class of shares. Ms. Bush,
Mr. Perna and Ms. Piret are the current nominees for election for each fund.
Ms. Bush and Mr. Perna are each elected by the holders of Common and Preferred
Shares. Ms. Piret is elected by the holders of Preferred Shares, only. The
affirmative vote of a plurality of the Common and Preferred Shares for each
fund present at the meeting in person or by proxy, voting together as a single
class, is required to elect such nominee for Trustee designated to be elected
by the Common and Preferred Shares. The affirmative vote of a plurality of the
Preferred Shares for each fund present at the meeting in person or by proxy is
required to elect such nominee for Trustee designated to be elected by the
Preferred Shares. This means that the three nominees receiving the greatest
number of votes will be elected as Class II Trustees to the Board of Pioneer
Tax Advantaged Balanced Trust and Class III Trustees to the Board of Pioneer
Floating Rate Trust.

Recommendation
For the reasons set forth above, the Trustees of your fund unanimously
recommend that shareholders vote in favor of each of the nominees.

AUDITOR INFORMATION

Young LLP for its audit of each fund's annual financial statements and fees
related to consents and comfort letters for the two most recent fiscal years
contained in the annual reports filed by each fund for such years were as
follows:

For the fiscal year For the fiscal year

Audit-related fees
The following are aggregate fees billed for assurance and related services
by Ernst & Young LLP to each fund that are related to the review of each fund's
semi-annual financial statements and agreed upon procedures related to the
ratings of each fund's Preferred Shares for the two most recent fiscal years.
All of these services were approved by the Audit Committee of each fund
pursuant to Regulation S-X.

All other fees

to the funds.

Affiliates' Fees for Non-Audit Services Required to be Pre-Approved
Beginning with non-audit service contracts entered into on or after May 6,
2003, the effective date of the new SEC pre-approval rules, each fund's audit
committee is required to pre-approve services to affiliates as 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 fund. Affiliates include the
fund's investment adviser and any entity controlling, controlled by, or under
common control with the adviser that provides ongoing services to the fund
(hereinafter referred to as "affiliates" of the fund). For the years ended
November 30, 2005 and 2004, for each of the funds, there were no services
provided to an affiliate that required the fund's audit committee pre-approval.

General Audit Committee Approval Policy

o For all projects, the officers of the funds and the funds' independent
registered public accounting firm 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 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
independent registered public accounting firm as set forth in the above
policy.

Aggregate Non-Audit Fees
The aggregate non-audit fees for each fund and its affiliates, as
previously defined, were as follows. These fees include services provided prior
to May 6, 2003, the effective date of the pre-approval process.

For the fiscal year For the fiscal year
ended 11/30/2005 ended 11/30/2004
--------------------- --------------------

Pioneer Floating Rate Trust ................... $21,300 n/a
Pioneer Tax Advantaged Balanced Trust ......... $15,300 $19,000

The Audit Committee of the Board of each fund has considered whether the
provision of services, other than audit services, by Ernst & Young LLP to each
fund and its affiliates is compatible with maintaining Ernst & Young LLP's
independence in performing audit services.

Representatives of Ernst & Young LLP will be available at the shareholder
meeting (either in person or via telephone), will have the opportunity to make
a statement should they desire to do so, and will be available to answer
questions.

Shareholder proposals
If you wish to include a proposal in your fund's proxy statement for the
2007 annual meeting, your proposal must be received by the Secretary of the
fund at the fund's principal offices at 60 State Street, Boston, Massachusetts
02109 on or before March 14, 2007. A proposal that is not to be included in the
fund's proxy statement may only be made at the 2007 annual meeting if it is
received by the Secretary of the fund at the fund's principal offices at 60
State Street, Boston, Massachusetts 02109 not more than 120 days and at least
90 days before the anniversary date of the mailing of the fund's proxy
materials for this year's annual meeting provided, however, that in the event
that the date of the mailing of the notice for the 2007 annual meeting is
advanced or delayed by more than thirty (30) days from the anniversary date of
the mailing of the notice for this year's annual meeting, notice by a
shareholder to be timely must be so delivered not earlier than the close of
business on the 120th day prior to the date of mailing of the notice for the
2007 annual meeting and not later than the close of business on the later of
the 90th day prior to the date of mailing of the notice for the 2007 annual
meeting or the 10th day following the day on which public announcement of the
date of mailing of the notice for the 2007 meeting is first made by the fund.

The submission by a shareholder of a proposal for inclusion in a proxy
statement does not guarantee that it will be included. Each fund currently
expects to hold the next annual shareholders' meeting on or about June 26,
2007, which date is subject to change. Shareholder proposals are subject to
certain regulations under the federal securities laws.

Proxies, quorum and voting at the meeting
Any shareholder who has given his or her proxy to someone has the power to
revoke that proxy at any time prior to its exercise by executing a superseding
proxy or by submitting a notice of revocation to the secretary of the fund. In
addition, although mere attendance at the meeting will not revoke a proxy, a
shareholder present at the meeting may withdraw his or her proxy and vote in
person. All properly executed and unrevoked proxies received in time for the
meeting will be voted in accordance with the instructions contained in the
proxies. If no instruction is given, the persons named as proxies will vote the
shares represented thereby in favor of the nominees in Proposal No. 1, as
described above, and will use their best judgment in connection with the
transaction of such other business as may properly come before the meeting or
any adjournment thereof.

For each fund, one-third of the outstanding shares of each series or
class, or one-third of the outstanding shares of the Trust, entitled to vote,
present in person or represented by proxy, constitutes a quorum for the
transaction of business at the meeting with respect to such series or class, or
with respect to the entire fund, respectively. In the event that at the time
any session of the meeting is called to order a quorum is not present in person
or by proxy, the persons named as proxies may vote those proxies that have been
received to adjourn the shareholder meeting to a later date. In the event that
a quorum is present but sufficient votes in favor of the proposal have not been
received, the persons named as proxies may propose one or more adjournments of
the shareholder meeting to permit further solicitation of proxies with respect
to such proposal. Any such adjournment will require the affirmative vote of
more than one half of the shares of the

fund present in person or by proxy at the session of the meeting to be
adjourned. The persons named as proxies will vote those proxies which they are
entitled to vote in favor of any such proposal in favor of such an adjournment
and will vote those proxies required to be voted against any such proposal
against any such adjournment. A shareholder vote may be taken on one or more of
the proposals in the proxy statement prior to such adjournment if sufficient
votes for its approval have been received and it is otherwise appropriate. Such
vote will be considered final regardless of whether the meeting is adjourned to
permit additional solicitation with respect to any other proposal.

Shares of the fund represented in person or by proxy, including shares
that abstain or do not vote with respect to a proposal, will be counted for
purposes of determining whether there is a quorum at the meeting. However, an
abstention from voting has the same effect as a vote against a proposal.
Similarly, if a broker or nominee holding shares in "street name" indicates on
the proxy card that it does not have discretionary authority to vote on a
proposal and has not received instructions from the beneficial owner, those
shares will not be considered present and entitled to vote on that proposal.
Thus, a "broker non-vote" has no effect on the voting.

Other business
While the meeting has been called to transact any business that may
properly come before it, the only matters that the Trustees intend to present
are those matters stated in the attached notice of annual meeting of
shareholders. However, if any additional matters properly come before the
meeting, and on all matters incidental to the conduct of the meeting, it is the
intention of the persons named in the enclosed proxy to vote the proxy in
accordance with their judgment on such matters unless instructed to the
contrary.

Method of solicitation and expenses
The cost of preparing, assembling and mailing this proxy statement and the
attached notice of annual meeting of shareholders and the accompanying proxy
card for each fund will be borne by that fund. In addition to soliciting
proxies by mail, Pioneer may, at the fund's expense, have one or more of the
fund's officers, representatives or compensated third-party agents, including
Pioneer, PIMSS and PFD, aid in the solicitation of proxies by personal
interview or telephone and telegraph and may request brokerage houses and other
custodians, nominees and fiduciaries to forward proxy soliciting material to
the beneficial owners of the shares held of record by such persons.

Each fund may also arrange to have votes recorded by telephone, the
internet or other electronic means. The voting procedures used in connection
with such voting methods are designed to authenticate shareholders' identities,
to allow shareholders to authorize the voting of their shares in accordance
with their instructions and to confirm that their instructions have been
properly recorded. If these procedures were subject to a successful legal
challenge, such votes would not be counted at the shareholder meeting. Each
fund is unaware of any such challenge at this time. In the case of telephone
voting, shareholders would be called at the phone number the sub-transfer
agent, Mellon Investor Services LLC, has in its records for their accounts, and
would be asked for their Social Security number or other identifying
information. The shareholders would then be given an opportunity to authorize
proxies to vote their shares at the meeting in accordance with their
instructions.

In the case of automated telephone and internet voting, shareholders would be
required to provide their Social Security number or other identifying
information and would receive a confirmation of their instructions.

Persons holding shares as nominees will be reimbursed by Pioneer, upon
request, for the reasonable expenses of mailing soliciting materials to the
principals of the accounts.
