Report of Independent Registered Public
Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer Tax Free Income Fund
In planning and performing our audit of the
financial statements of Pioneer Tax Free Income
Fund (the Company) as of and for the year ended
December 31, 2008, in accordance with the
standards of the Public Company Accounting
Oversight Board (United States), we considered
the Company's internal control over financial
reporting, including controls over safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our
opinion on the financial statements and to comply
with the requirements of Form N-SAR, but not for
the purpose of expressing an opinion on the
effectiveness of the Company's  internal control
over financial reporting. Accordingly, we express
no such opinion.
The management of the Company is responsible
for establishing and maintaining effective internal
control over financial reporting. In fulfilling this
responsibility, estimates and judgments by
management are required to assess the expected
benefits and related costs of controls. A
company's internal control over financial reporting
is a process designed to provide reasonable
assurance regarding the reliability of financial
reporting and the preparation of financial
statements for external purposes in accordance
with generally accepted accounting principles. A
company's internal control over financial reporting
includes those policies and procedures that (1)
pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the
company; (2) provide reasonable assurance that
transactions are recorded as necessary to permit
preparation of financial statements in accordance
with generally accepted accounting principles,
and that receipts and expenditures of the
company are being made only in accordance with
authorizations of management and directors of
the company; and (3) provide reasonable
assurance regarding prevention or timely
detection of unauthorized acquisition, use or
disposition of a company's assets that could have
a material effect on the financial statements.
Because of its inherent limitations, internal control
over financial reporting may not prevent or detect
misstatements. Also, projections of any
evaluation of effectiveness to future periods are
subject to the risk that controls may become
inadequate because of changes in conditions, or
that the degree of compliance with the policies or
procedures may deteriorate.
A deficiency in internal control over financial
reporting exists when the design or operation of a
control does not allow management or
employees, in the normal course of performing
their assigned functions, to prevent or detect
misstatements on a timely basis. A material
weakness is a deficiency, or a combination of
deficiencies, in internal control over financial
reporting, such that there is a reasonable
possibility that a material misstatement of the
company's annual or interim financial statements
will not be prevented or detected on a timely
basis.
Our consideration of the Company's internal
control over financial reporting was for the limited
purpose described in the first paragraph and
would not necessarily disclose all deficiencies in
internal control that might be material
weaknesses under standards established by the
Public Company Accounting Oversight Board
(United States).  However, we noted no
deficiencies in the Company's internal control
over financial reporting and its operation,
including controls over safeguarding securities,
that we consider to be a material weakness as
defined above as of December 31, 2008.
This report is intended solely for the information
and use of management and the Board of
Trustees of Pioneer Tax Free Income Fund and
the Securities and Exchange Commission and is
not intended to be and should not be used by
anyone other than these specified parties.
