INDEPENDENT AUDITORS' REPORT
The Board of Directors
Seligman Municipal Fund Series, Inc.
In planning and performing our audit of the financial statements of Seligman
Municipal Fund Series, Inc. (formerly Seligman Tax-Exempt Fund Series, Inc.)
(the "Series") for the year ended September 30, 1996, we considered its internal
control structure, including procedures for safeguarding securities, in order to
determine our auditing procedures for the purpose of expressing an opinion on
the financial statements and to comply with the requirements of Form N-SAR, not
to provide assurance on the internal control structure.
The management of the Series is responsible for establishing and maintaining an
internal control structure. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected benefits and related
costs of internal control structure policies and procedures. Two of the
objectives of an internal control structure are to provide management with
reasonable, but not absolute, assurance that assets are safeguarded against loss
from unauthorized use or disposition and that transactions are executed in
accordance with management's authorization and recorded properly to permit the
preparation of financial statements in conformity with generally accepted
accounting principles.
Because of the inherent limitations in any internal control structure, errors or
irregularities may occur and not be detected. Also, projection of any evaluation
of the structure to future periods is subject to the risk that it may be
inadequate because of changes in conditions or that the effectiveness of the
design and operation may deteriorate.
Our consideration of internal control structure would not necessarily disclose
all matters in the internal control structure that might be material weaknesses
under standards established by the American Institute of Certified Public
Accountants. A material weakness is a condition in which the design or operation
of the specific internal control structure elements does not reduce to a
relatively low level the risk that errors or irregularities in amounts that
would be material in relation to the financial statements being audited may
occur and not be detected within a timely period by employees in the normal
course of performing their assigned functions. However, we noted no matters
involving the internal control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined above as of
September 30, 1996.
This report is intended solely for the information and use of management and the
Securites and Exchange Commission.
