INTERNAL CONTROL RPT

Report of Independent Registered Public Accounting Firm

To the Shareholders and

Board of Trustees of MFS Intermediate High Income Fund

In planning and performing our audit of the financial statements of MFS Intermediate High Income Fund (the “Fund”) as of and for the year ended November 30, 2019, in accordance with the standards of the Public Company Accounting Oversight Board (United States), we considered the Fund’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-CEN, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

The management of the Fund 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 U.S. 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 U.S. 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 Fund’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 Fund’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 November 30, 2019.

This report is intended solely for the information and use of management and the Board of Trustees of MFS Intermediate High 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.

Section 2.  Shareholders

2.1       Shareholder Meetings.  Except as provided in the next sentence, regular meetings of the shareholders for the election of Trustees and the transaction of such other business as may properly come before the meeting shall be held, so long as Shares are listed for trading on the New York Stock Exchange, on at least an annual basis, on such day and at such place as shall be designated by a majority of the Trustees.  In the event that such a meeting is not held in any annual period if so required, whether the omission be by oversight or otherwise, a subsequent special meeting may be called by a majority of the Trustees and held in lieu of such meeting with the same effect as if held within such annual period.  A Special meeting of the shareholders of the Trust may be called at any time by a majority of the Trustees, by the president or, if a majority of the Trustees and the president shall fail to call any meeting of shareholders for a period of 30 days after written application of one or more shareholders who hold at least 10% of all outstanding shares of the Trust, then such shareholders may call such meeting.  Each call of a meeting shall state the place, date, hour and purposes of the meeting.

2.2       Advance Notice of Shareholder Nominees for Trustees and Other Shareholder Proposals.

(a)  As used in this Section 2.2, the term “annual meeting” refers to any annual meeting of shareholders as well as any special meeting held in lieu of an annual meeting as described in the first two sentences of Section 2.1 of these Bylaws, and the term “special meeting” refers to all meetings of shareholders other than an annual meeting or a special meeting in lieu of an annual meeting.

(b)  The matters proposed by shareholders to be considered and brought before any annual or special meeting of shareholders shall be limited to only such matters, including the nomination and election of Trustees, as shall be brought properly before such meeting in compliance with the procedures set forth in this Section 2.2.  Only persons who are nominated in accordance with the procedures set forth in this Section 2.2 shall be eligible for election as Trustees, and no proposal to fix the number of Trustees shall be brought before an annual or special meeting of shareholders or otherwise considered unless in accordance with the procedures set forth in this Section 2.2.

(c)  For any matter to be properly before any annual meeting, the matter must be (i) specified in the notice of meeting given by or at the direction of a majority of the Trustees pursuant to Section 2.4 of these Bylaws, or (ii) brought before the meeting in the manner specified in this Section 2.2(c) by a shareholder of record entitled to vote at the meeting or by a shareholder (a “Beneficial Owner”) that holds Shares entitled to vote at the meeting through a nominee or “street name” holder of record and that can demonstrate to the Trust such indirect ownership and such Beneficial Owner’s entitlement to vote such Shares, provided that the shareholder was the shareholder of record or the Beneficial Owner held such Shares at the time the notice provided for in this Section 2.2(c) is delivered to the secretary.

In addition to any other requirements under applicable law and the Declaration of Trust and these Bylaws, persons nominated by shareholders for election as Trustees and any other proposals by shareholders may be properly brought before an annual meeting only pursuant to timely notice (the “Shareholder Notice”) in writing to the secretary.  To be timely, the Shareholder Notice must be delivered to or mailed and received at the principal executive offices of the Trust not less than forty-five (45) nor more than sixty (60) days prior to the first anniversary date of the date on which the Trust first sent its proxy materials for the prior year’s annual meeting; provided, however, with respect to the annual meetings to be held in the calendar years 2008 and 2009, the Shareholder Notice must be so delivered or mailed and so received on or before March 18, 2008, and May 1, 2009, respectively; provided further, however, if and only if the annual meeting is not scheduled to be held within a period that commences thirty (30) days before the first anniversary date of the annual meeting for the preceding year and ends thirty (30) days after such anniversary date (an annual meeting date outside such period being referred to herein as an “Other Annual Meeting Date”), such Shareholder Notice must be given in the manner provided herein by the later of the close of business on (i) the date forty-five (45) days prior to such Other Annual Meeting Date or (ii) the tenth (10th) business day following the date such Other Annual Meeting Date is first publicly announced or disclosed.

2

Any shareholder desiring to nominate any person or persons (as the case may be) for election as a Trustee or Trustees of the Trust shall deliver, as part of such Shareholder Notice:  (i) a statement in writing setting forth (A) the name, age, date of birth, business address, residence address and nationality of the person or persons to be nominated; (B) the number of all Shares of the Trust owned of record or beneficially by each such person or persons, as reported to such shareholder by such nominee(s); (C) any other information regarding each such person required by paragraphs (a), (d), (e) and (f) of Item 401 of Regulation S-K or paragraph (b) of Item 22 of Rule 14a-101 (Schedule 14A) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), adopted by the Securities and Exchange Commission (or the corresponding provisions of any regulation or rule subsequently adopted by the Securities and Exchange Commission or any successor agency applicable to the Trust); (D) any other information regarding the person or persons to be nominated that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitation of proxies for election of Trustees or directors pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; and (E) whether such shareholder believes any nominee is or will be an “interested person” of the Trust (as defined in the Investment Company Act of 1940, as amended) and, if not an “interested person,” information regarding each nominee that will be sufficient for the Trust to make such determination; and (ii) the written and signed consent of the person or persons to be nominated to be named as nominees and to serve as Trustees if elected.  In addition, a majority of the Trustees may require any proposed nominee to furnish such other information as they may reasonably require or deem necessary to determine the eligibility of such proposed nominee to serve as a Trustee.  Any Shareholder Notice required by this Section 2.2(c) in respect of a proposal to fix the number of Trustees shall also set forth a description of and the text of the proposal, which description and text shall state a fixed number of Trustees that otherwise complies with applicable law, these Bylaws and the Declaration of Trust.

Without limiting the foregoing, any shareholder who gives a Shareholder Notice of any matter proposed to be brought before a shareholder meeting (whether or not involving nominees for Trustees) shall deliver, as part of such Shareholder Notice:  (i) the description of and text of the proposal to be presented; (ii) a brief written statement of the reasons why such shareholder favors the proposal; (iii) such shareholder’s name and address as they appear on the Trust’s books; (iv) any other information relating to the shareholder that would be required to be disclosed in a proxy statement or other filings required to be made in connection with the solicitation of proxies with respect to the matter(s) proposed pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; (v) the number of all Shares of the Trust owned beneficially and of record by such shareholder; (vi) any material interest of such shareholder in the matter proposed (other than as a shareholder); (vii) a representation that the shareholder intends to appear in person or by proxy at the shareholder meeting to act on the matter(s) proposed; (viii) if the proposal involves nominee(s) for Trustees, a description of all arrangements or understandings between the shareholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by the shareholder; and (ix) in the case of a Beneficial Owner, evidence establishing such Beneficial Owner’s indirect ownership of, and entitlement to vote, Shares at the meeting of shareholders.  As used in this Section 2.2, Shares “beneficially owned” shall mean all Shares which such person is deemed to beneficially own pursuant to Rules 13d-3 and 13d-5 under the Exchange Act.

3

(d)  For any matter to be properly before any special meeting, the matter must be specified in the notice of meeting given by or at the direction of a majority of the Trustees pursuant to Section 2.4 of these Bylaws.  In the event the Trust calls a special meeting for the purpose of electing one or more Trustees, any shareholder may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Trust’s notice of meeting if and only if the shareholder provides a notice containing the information required in the Shareholder Notice to the secretary required with respect to annual meetings by Section 2.2(c) hereof, and such notice is delivered to or mailed and received at the principal executive office of the Trust not later than the close of business on the tenth (10th) day following the day on which the date of the special meeting and of the nominees proposed by a majority of the Trustees to be elected at such meeting are publicly announced or disclosed.

(e)  For purposes of this Section 2.2, a matter shall be deemed to have been “publicly announced or disclosed” if such matter is disclosed in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service, in a document publicly filed by the Trust with the Securities and Exchange Commission, or in a Web site accessible to the public maintained by the Trust or by its investment adviser or an affiliate of such investment adviser with respect to the Trust.

(f)  In no event shall an adjournment or postponement (or a public announcement thereof) of a meeting of shareholders commence a new time period (or extend any time period) for the giving of notice as provided in this Section 2.2.

(g)  The person presiding at any meeting of shareholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall have the power and duty to (i) determine whether a nomination or proposal of other matters to be brought before a meeting and notice thereof have been duly made and given in the manner provided in this Section 2.2 and elsewhere in these Bylaws and the Declaration of Trust and (ii) if not so made or given, to direct and declare at the meeting that such nomination and/or such other matters shall be disregarded and shall not be considered.  Any determination by the person presiding shall be binding on all parties absent manifest error.

(h)  Notwithstanding anything to the contrary in this Section 2.2 or otherwise in these Bylaws, unless required by federal law, no matter shall be considered at or brought before any annual or special meeting unless such matter has been approved for these purposes by a majority of the Trustees and, in particular, no Beneficial Owner shall have any rights as a shareholder except as may be required by federal law.  Furthermore, nothing in this Section 2.2 shall be construed as creating any implication or presumption as to the requirements of federal law.

4

            2.3       Place of Meetings.  All meetings of the shareholders shall be held at the principal office of the Trust, or, to the extent permitted by the Declaration of Trust, at such other place within the United States as shall be designated by the Trustees or the president of the Trust.

2.4       Notice of Meetings.  A written notice of each meeting of shareholders, stating the place, date and hour and the purposes of the meeting, shall be given at least seven days before the meeting to each shareholder entitled to vote thereat by leaving such notice with him or at his residence or usual place of business or by mailing it, postage prepaid, and addressed to such shareholder at his address as it appears in the records of the Trust.  Such notice shall be given by the secretary or an assistant secretary or by an officer designated by the Trustees.  No notice of any meeting of shareholders need be given to a shareholder if a written waiver of notice, executed before or after the meeting by such shareholder or his attorney thereunto duly authorized, is filed with the records of the meeting.

2.5       Ballots.  No ballot shall be required for any election unless requested by a shareholder present or represented at the meeting and entitled to vote in the election.

2.6       Proxies.  Shareholders entitled to vote may vote either in person or by proxy in writing dated not more than six months before the meeting named therein, which proxies shall be filed with the secretary or other person responsible to record the proceedings of the meeting before being voted.  Unless otherwise specifically limited by their terms, such proxies shall entitle the holders thereof to vote at any adjournment of such meeting but shall not be valid after the final adjournment of such meeting.  The placing of a shareholder's name on a proxy pursuant to telephonic or electronically transmitted instructions obtained pursuant to procedures reasonably designed to verify that such instructions have been authorized by such shareholder shall constitute execution of such proxy by or on behalf of such shareholder.

Section 3.  Trustees

3.1       Committees and Advisory Board.  The Trustees may appoint from their number an executive committee and other committees.  Except as the Trustees may otherwise determine, any such committee may make rules for conduct of its business.  The Trustees may appoint an advisory board to consist of not less than two nor more than five members.  The members of the advisory board shall be compensated in such manner as the Trustees may determine and shall confer with and advise the Trustees regarding the investments and other affairs of the Trust.  Each member of the advisory board shall hold office until the first meeting of the Trustees following the next meeting of the shareholders and until his successor is elected and qualified, or until he sooner dies, resigns, is removed, or becomes disqualified, or until the advisory board is sooner abolished by the Trustees.

3.4       Notice.  It shall be sufficient notice to a Trustee to send notice by mail at least forty-eight hours or by telegram at least twenty-four hours before the meeting addressed to the Trustee at his or her usual or last known business or residence address or to give notice to him or her in person or by telephone at least twenty-four hours before the meeting.  Notice of a meeting need not be given to any Trustee if a written waiver of notice, executed by him or her before or after the meeting, is filed with the records of the meeting, or to any Trustee who attends the meeting without protesting prior thereto or at its commencement the lack of notice to him or her.  Neither notice of a meeting nor a waiver of a notice need specify the purposes of the meeting.

3.5Quorum.  At any meeting of the Trustees one-third of the Trustees then in office shall constitute a quorum; provided, however, a quorum shall not be less than two.  Any meeting may be adjourned from time to time by a majority of the votes cast upon the question, whether or not a quorum is present, and the meeting may be held as adjourned without further notice.

Section 13.  Claims and Disputes

13.1     Forum for Adjudication of Disputes.  Unless the Trust consents in writing to the selection of an alternative forum, (i) any action or proceeding brought by or on behalf of the Trust or any of the Trust’s Shareholders, (ii) any action asserting a claim against the Trust (or a series thereof), or against any trustee, officer or other employee of the Trust, whether arising under federal law, the law of any state, or the law of a non-U.S. jurisdiction, (iii) any action asserting a claim arising pursuant to any provision of the Massachusetts Business Corporation Act, the statutory or common law of the Commonwealth of Massachusetts, the Declaration or these By-Laws, (iv) any action to interpret, apply, enforce or determine the validity of the Declaration, these By-Laws, or any agreement on behalf of the Trust authorized thereunder, or (v) any action asserting a claim governed by the internal affairs doctrine (each, a "Covered Action") shall be brought in the state or federal courts located within the Commonwealth of Massachusetts. Any person purchasing or otherwise acquiring or holding any interest in shares of beneficial interest of the Trust shall be (i) deemed to have notice of and consented to the provisions of this Section, and (ii) deemed to have waived any argument relating to the inconvenience of the forums referenced above in connection with any action or proceeding described in this Section.

If any Covered Action is filed in a court other than the state or federal courts of the Commonwealth of Massachusetts (a “Foreign Action”) in the name of any shareholder, such shareholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the Commonwealth of Massachusetts in connection with any action brought in any such courts to enforce the first paragraph of this Section (an “Enforcement Action”) and (ii) having service of process made upon such shareholder in any such Enforcement Action by service upon such shareholder’s counsel in the Foreign Action as agent for such shareholder.

9

If any provision or provisions of this Section shall be held to be invalid, illegal or unenforceable as applied to any person or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provision(s) in any other circumstance and of the remaining provisions of this Section (including, without limitation, each portion of any sentence of this Section containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons and circumstances shall not in any way be affected or impaired thereby.

            13.2     Claims.  As used herein, a “direct Shareholder claim" shall refer to (i) a claim based upon alleged violations of a Shareholder’s individual rights independent of any harm to the Trust, including a Shareholder’s voting rights under Article III, rights to receive a dividend payment as may be declared from time to time, rights to inspect books and records, or other similar rights personal to the Shareholder and independent of any harm to the Trust; and (ii) a claim for which a direct shareholder action is expressly provided under the U.S. federal securities laws. Any claim asserted by a Shareholder that is not a direct Shareholder claim, including without limitation any claims purporting to be brought on behalf of the Trust or involving any alleged harm to the Trust, shall be considered a “derivative claim" as used herein.

a. Derivative Claims.  No Shareholder shall have the right to bring or maintain any court action or other proceeding asserting a derivative claim or any claim asserted on behalf of the Trust or involving any alleged harm to the Trust without first making demand on the Trustees requesting the Trustees to bring or maintain such action, proceeding or claim. Such demand shall be excused only when the plaintiff makes a specific showing that irreparable nonmonetary injury to the Trust or any series or class thereof would otherwise result, or if a majority of the Board of Trustees, or a majority of any committee established to consider the merits of such action, has a material personal financial interest in the action at issue. A Trustee shall not be deemed to have a personal financial interest in an action or otherwise be disqualified from ruling on a Shareholder demand by virtue of the fact that such Trustee receives remuneration from his or her service on the Board of Trustees of the Trust or on the boards of one or more investment companies with the same or an affiliated investment adviser or underwriter, or the amount of such remuneration. Such demand shall be mailed to the Secretary of the Trust at the Trust’s principal office and shall set forth with particularity the nature of the proposed court action, proceeding or claim and the essential facts relied upon by the shareholder to support the allegations made in the demand. The Trustees shall consider such demand within 90 days of its receipt by the Trust. In their sole discretion, the Trustees may submit the matter to a vote of shareholders of the Trust or series or class of Shares, as appropriate. Any decision by the Trustees to bring, maintain or settle (or not to bring, maintain or settle) such court action, proceeding or claim, or to submit the matter to a vote of Shareholders, shall be binding upon the Shareholders.

You should not draw any conclusions about the fund's investment performance from the amount of this distribution or from the terms of the fund's managed distribution plan.
The fund estimates that it has distributed more than its income and capital gains; therefore, a portion of your distribution may be a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the fund is paid back to you. A return of capital distribution does not necessarily reflect the fund's investment performance and should not be confused with "yield" or "income." The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax-reporting purposes. The actual amounts and sources of the amounts for tax-reporting purposes will depend upon the fund's investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes. If you have any questions regarding this information, please call our fund service department at 1-800-637-2304 any business day from 9 a.m. to 5 p.m. Eastern time.
