The Board of Trustees of MFS Municipal Income Trust ("MFM") has approved
 changes to the investment objective and policies of the
fund.  Effective December 21, 2007, MFM's investment objective of seeking
 "high current income exempt from federal income tax" was
revised to provide that MFM will seek "high current income exempt from federal
 income tax but may also consider capital
appreciation."  Significant changes to MFM's principal investment strategies
 are described below.

The percentage limitation of investing less than 15% of the fund's assets in
 restricted securities has been eliminated to allow the
portfolio manager more flexibility to invest in appropriate securities.

The percentage limitation of investing 65% of the fund's assets in tax-exempt
 securities rated below the three highest rating
categories has been eliminated and the fund's principal investment strategy
 states, " MFS may invest up to 100% of the fund's assets
in lower quality debt instruments, including those that are in default."

The principal investment strategy of investing a high percentage of the fund's
 assets in the same geographic area or revenue bonds
and less than 25% of the fund's assets in industrial revenue bonds has been
 eliminated and replaced with:  "MFS may invest 25% or
more of the fund's total assets in municipal instruments that finance similar
 projects, such as those relating to education,
healthcare, housing, utilities, water, or sewers."
