In planning and performing our audit of the financial statements
of Morgan Stanley Dean Witter Municipal Income Trust (the "Fund")
for the year ended August 31, 1999, we considered its internal
control, including control activities for safeguarding
securities, in order to determine our auditing procedures for the
purpose of expressing our opinion on the financial statements and
to comply with the requirements of Form N-SAR, not to provide
assurance on internal control.
The management of the Fund is responsible for establishing and
maintaining internal control. In fulfilling this responsibility,
estimates and judgments by management are required to assess the
expected benefits and related costs of controls. Generally,
controls that are relevant to an audit pertain to the entity's
objective of preparing financial statements for external purposes
that are fairly presented in conformity with generally accepted
accounting principles. Those controls include the safeguarding
of assets against unauthorized acquisition, use or disposition.
Because of inherent limitations in internal control, errors or
fraud may occur and not be detected. Also, projection of any
evaluation of internal control to future periods is subject to
the risk that it may become inadequate because of changes in
conditions or that the effectiveness of the design and operation
may deteriorate.
Our consideration of internal control would not necessarily
disclose all matters in internal control 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 one or more of the
internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud 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
internal control and its operation, including controls for
safeguarding securities, that we consider to be material
weaknesses as defined above as of August 31, 1999.
