Item 3.
Source and Amount of Funds or Other Consideration.
 
Karpus, an independent registered investment advisor, has accumulated 2,687,046 Shares on behalf of accounts that are managed by Karpus (the "Accounts") under limited powers of attorney, which represents approximately 23.2% of the Issuer's outstanding shares. All funds that have been utilized in making such purchases are from such Accounts. The aggregate purchase price of the 2,687,046 Shares beneficially owned by Karpus is approximately $25,687,367, excluding brokerage commissions.

Purpose of Transaction.
 
Karpus, an independent registered investment advisor, with a specialty focus in closed-end funds, believes that the profile of the Issuer fit the investment guidelines for various Accouts. Shares have been acquired since March 15, 2013.

The Reporting Persons purchased the Shares based on the Reporting Persons' belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.
 
No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. In addition, Karpus may contact the Issuer with regards to concerns that they have with respect to the Issuer.
 
Item 5.
Interest in Securities of the Issuer.
 
The aggregate percentage of Shares reported owned by each Reporting Person is based upon 11,586,957 Shares outstanding, which is the total number of Shares outstanding as of November 30, 2016 as reported in the Issuer’s Annual Report to Shareholders, filed with the U.S. Securities and Exchange Commission on January 30, 2017.

14a-8 Shareholder Proposal Sent to the Fund on April 11, 2017
 

VIA FEDERAL EXPRESS 								April 11, 2017

Mark N. Polebaum, Secretary
MFS Investment Grade Municipal Trust
111 Huntington Avenue
Boston, Massachusetts 02199

Re:	MFS Investment Grade Municipal Trust ("CXH" or the "Fund"), CUSIP: 59318B108

Mr. Polebaum:
This letter shall serve as notice to the MFS Investment Grade Municipal Trust ("CXH" or the "Fund"), as to Karpus Management, Inc.'s ("Karpus") timely submittal of a shareholder proposal pursuant to Rule 14a-8 of the Securities Exchange Act of 1934 for presentation to CXH shareholders at the Fund's next annual shareholders' meeting anticipated to be held in October 2017, or any postponement or adjournment thereof (the "Meeting").

Karpus' non-binding 14a-8 shareholder proposal (the "Proposal") is as follows:

    BE IT RESOLVED, the shareholders of the MFS Investment Grade Municipal Trust ("CXH" or the "Fund") request that the Board of Trustees promptly consider authorizing a self-tender offer for all outstanding common shares of the Fund at or close to net asset value ("NAV"). If more than 50% of the Fund's outstanding common shares are tendered, the tender offer should be cancelled and the Board should take the steps necessary to liquidate, merge, or convert the Fund to an open-end mutual fund or exchange traded fund.

    Supporting Statement

    Closed-end funds trade as a function of supply and demand. As such, many factors weigh into whether market participants deem a fund worthy of being a part of their portfolio. With respect to CXH, because of the Fund's persistent discount and relatively low trading volume, one could conclude that there is a substantial lack of overall demand.

    Fortunately, closed-end fund boards have tools to address such issues. In fact, many funds, such as CXH, have language in their prospectus to address persistent discounts. The Fund's prospectus states: "the trust may repurchase its shares from time to time in the open market or otherwise as and when it is deemed advisable by the trustees." The prospectus further provides language where shareholder can ask the Trustees to put forth an open-ending proposal if certain conditions are met.

    Despite having this language, to our knowledge we are not aware of any such actions being taken for the Fund's common shares. As an investor, we cannot understand why the Trustees would not take more aggressive or committed measures to address the Fund's persistent discount.

    The Fund's own prospectus anticipates that it may need to take action from time to time to reduce a persistent discount. Now is clearly that time. Our proposal, if approved and implemented, would take steps toward the type of action that it doesn't appear the Trustees are willing to consider on behalf of shareholders. If put in place and a majority of outstanding shares are tendered, this would indicate that shareholders do not support the Fund continuing in its closed-end fund format.

    Even though the Board is likely to come up with a wide range of excuses as to why they have not implemented actions like those we are proposing, MFS' own proxy guidelines state they will: "support proposals to institute share repurchase plans in which all shareholders have the opportunity to participate on an equal basis. Such plans may include a company acquiring its own shares in the open market, or a company making a tender offer to its own shareholders."

    Why do they not hold themselves to the same standards that they hold for their portfolios' investments?

    Please vote FOR Karpus' Proposal and tell our Fund's Trustees that you want them to take action to narrow CXH's discount and offer shareholders liquidity at or near net asset value for their shares.

    END OF PROPOSAL

As is required by Rule 14a-8, attached as Exhibits 1 and 2 are letters from U. S. Bank N.A. and the "record" holder of the referenced shares, verifying that the referenced shares were continuously and beneficially owned, and had a market value of $2,000 or more, for at least a one year period prior to the date of the submittal of the above Proposal. Karpus intends to hold the shares referenced through the date of the Meeting.

Please advise us immediately if this notice is deficient in any way or if any additional information is required so that Karpus may promptly provide it in order to cure any deficiency.

Sincerely,


/s/ Brett D. Gardner
