RE: MORGAN STANLEY INCOME TRUST
    (FILE NOS. 33-24245 AND 811-5654)

Dear Mr. Greene:

Thank you for your telephonic comments regarding the registration statement on
Form N-1A for Morgan Stanley Income Trust (the "Fund") filed with the Securities
and Exchange Commission on October 26, 2006. Below, we describe the changes made
to the registration statement in response to the Staff's comments and provide
any responses to or any supplemental explanations of such comments, as
requested. These changes will be reflected in post-effective amendment number 25
to the Fund's registration statement on Form N-1A, which will be filed via EDGAR
on or about December 20, 2006.

                  GENERAL COMMENTS TO FORM N-1A

COMMENT 1.  PLEASE FILE A RESPONSE LETTER TO THESE COMMENTS VIA EDGAR,
            INCLUDING THE "TANDY" PROVISION.

                 RESPONSE 1. This response letter addressing the Staff's
                 comments has been filed via EDGAR correspondence, including the
                 "Tandy" provision, separate from the corresponding
                 Post-Effective Amendment.

            COMMENTS TO THE PROSPECTUS

COMMENT 2.  PLEASE NOTE THAT CERTAIN SIDEBARS AND OTHER STATEMENTS IN THE
            PROSPECTUS APPEAR IN ALL CAPS IN THE EDGAR FILINGS WITH THE
            COMMISSION. PLEASE CONFIRM THAT THEY ARE NOT IN ALL CAPS AS THEY
            APPEAR IN THE PRINTED PROSPECTUS.

                 RESPONSE 2. This disclosure appears in italics in the Fund's
                 printed prospectus, not all caps.


                                        1

COMMENT 3.  PLEASE INCLUDE AN EXPLANATION IN THE PROSPECTUS ON WHAT RATINGS
            WOULD BE CONSIDERED "INVESTMENT GRADE" AND "JUNK BONDS" OR
            ALTERNATIVELY ADD A RATINGS APPENDIX TO THE END OF THE STATEMENT OF
            ADDITIONAL INFORMATION ("SAI").

                 RESPONSE 3. There is currently a ratings appendix attached
                 to the SAI.

COMMENT 4.  THE EIGHTH PARAGRAPH IN THE SECTION TITLED "PRINCIPAL INVESTMENT
            STRATEGIES" DISCUSSES THE FUND'S INVESTMENTS IN FIXED-INCOME
            SECURITIES RATED LOWER THAN INVESTMENT GRADE. PLEASE CONFIRM THAT
            THIS IS A PRIMARY INVESTMENT STRATEGY OF THE FUND.

                 RESPONSE 4. By virtue of the Fund's ability to invest up to 20%
                 in such securities, this is considered to be a primary
                 investment strategy of the Fund.

COMMENT 5.  ON PAGE 6 OF THE PROSPECTUS UNDER THE HEADING "OTHER RISKS,"
            DELETE ANY REFERENCE TO "SWAPS" WHICH IS A PRIMARY INVESTMENT
            STRATEGY.

                 RESPONSE 5. This disclosure has been revised accordingly.

COMMENT 6.  IN THE "FEES AND EXPENSES" SECTION OF THE PROSPECTUS, CONSIDER
            MOVING THE FOOTNOTES TO AFTER THE EXAMPLE.

                 RESPONSE 6. We respectfully acknowledge the comment, but
                 believe the current placement of the footnotes is appropriate.
                 We believe to move the footnotes to below the Example would
                 diminish the impact of the information and could result in a
                 shareholder being unable to locate the footnotes.

COMMENT 7.  IN THE "FEES AND EXPENSES" SECTION OF THE PROSPECTUS, PLEASE
            CONFIRM THAT THE NUMBERS IN THE TABLE ARE GROSS AMOUNTS AND NOT NET
            OF ANY WAIVERS CURRENTLY IN PLACE.

                 RESPONSE 7. The amounts shown in the table are the fees prior
                 to any waiver/assumption of expenses taken into account.

COMMENT 8.  PLEASE ATTACH AS AN EXHIBIT TO PART C THE WAIVER AGREEMENT IN
            CONNECTION WITH THE FEE WAIVER MENTIONED IN FOOTNOTE 6 IN THE "FEES
            AND EXPENSES" SECTION OF THE PROSPECTUS.

                 RESPONSE 8. This fee waiver is not a contractual waiver but a
                 voluntary waiver that may be terminated at any time. The
                 footnote has been revised to reflect its voluntary nature.

COMMENT 9.  IN THE "FEES AND EXPENSES OF THE PORTFOLIO" SECTION OF THE
            PROSPECTUS, IF APPLICABLE, DISCLOSE THAT THE INVESTMENT ADVISER HAS
            THE ABILITY TO RECOUP ANY FEES THAT IT WAIVED OR REIMBURSED IN
            SUBSEQUENT YEARS.

                 RESPONSE 9. The suggested disclosure is not applicable.


                                        2

COMMENT 10. PLEASE INCLUDE THE ORDER PROCESSING FEE IN THE FEE TABLE AS
            REQUIRED BY FORM N-1A UNLESS AN INVESTOR CAN PURCHASE SHARES WITHOUT
            BEING A MORGAN STANLEY CLIENT.

                 RESPONSE 10. Form N-1A requires that the costs and expenses
                 that an investor will bear directly or indirectly be included
                 in the fee table. The order processing fee that Morgan Stanley
                 DW Inc. charges clients when a client purchases or tenders
                 shares of the Fund is not required to be included in the fee
                 table because only investors that purchase shares through
                 Morgan Stanley DW Inc. would be subject to that fee.

            COMMENTS TO THE SAI

COMMENT 11. PLEASE ADD A DESCRIPTION OF THE FUND'S POLICIES WITH RESPECT TO
            BORROWING AND ISSUANCE OF SENIOR SECURITIES TO THE SAI.

                 RESPONSE 11. The SAI currently includes such disclosure. Please
                 see the section titled "Description of the Fund and Its
                 Investments and Risks - Investment Strategies and Risks -
                 Borrowing."

COMMENT 12. IN THE SECTION ENTITLED "FUND MANAGEMENT - PORTFOLIO MANAGER
            COMPENSATION STRUCTURE," (1) INCLUDE ONLY THE DISCRETIONARY
            COMPENSATION RECEIVED BY THE PORTFOLIO MANAGERS OF THE FUND DURING
            THE LAST YEAR AND (2) CONFIRM THAT YOU ARE PROVIDING THE REQUESTED
            INFORMATION.

                 RESPONSE 12. We believe the current disclosure is in compliance
                 with SEC Release 2004-89. This Release requires that the SAI
                 include disclosure regarding the structure of, and the method
                 used to determine, the compensation of its portfolio managers.
                 The Release notes that the purpose of this disclosure is to
                 help investors better understand a portfolio manager's
                 incentives in managing a fund and shed light on possible
                 conflicts of interest that could arise when a portfolio manager
                 manages other accounts. Therefore, in order to achieve this
                 purpose, the disclosure, in our view, should include all
                 possible forms of compensation that are available to the
                 portfolio manager in connection with managing the portfolio and
                 other accounts. Please note that we revised the disclosure to
                 clarify that investment performance, upon which a portfolio
                 manager's compensation is linked, is calculated for one-,
                 three-, and five-year periods measured against a
                 fund's/account's primary benchmark, indices and/or peer groups,
                 where applicable.
