DEAR SHAREHOLDER:
- -----------------------------------------------------------------------------

   Bonds have rallied significantly since last year. Progressive tightening
of monetary policy by the Federal Reserve Board over the 12 months through
February 1995 led to slower economic growth and caused bonds to advance. The
trend toward lower long-term interest rates was aided in July and December
when the Federal Reserve Board reduced the fed funds rate banks charge each
other for overnight loans.

MUNICIPAL MARKET CONDITIONS

   Long-term municipal bond yields declined from a high of 7.37 percent in
November 1994 to 5.78 percent at the end of November 1995, as tracked by The
Bond Buyer Revenue Bond Index*. This 159 basis point decline in yield
corresponded to a 12 percent price increase for a callable bond with a
30-year maturity. Similarly, yields on 1-year municipal notes moved from 4.51
percent to 3.59 percent. The yield pickup for extending maturity from 1-to-30
years was 219 basis points in November 1995.

   Tax-exempt bonds began the year by outperforming U.S. Treasury bonds. The
ratio of the Revenue Bond Index yields to the 30-year U.S. Treasury bond
yield moved from 89 percent in December 1994 to 84 percent by the end of
February 1995. A declining ratio means that municipal bond prices have been
stronger than U.S. Treasury prices. In the spring the municipal market began
to discount the risk of comprehensive changes in the tax code created by
flat-tax rhetoric from Washington. This caused municipals to weaken on a
relative basis. The yield ratio reached a high of 95 percent during the
summer. Over the past 10 years, long municipal yields have averaged 89
percent of U.S. Treasury yields.

   The municipal market continued to experience consolidation in 1995.
Municipal underwriting in the first 11 months of the year was down 12 percent
from the same period in 1994. This change followed a 44 percent drop in
volume for all of 1994. The effects of lower volume and diminished new issue
profitability were also apparent in the decision by several major dealers to
withdraw from the municipal business.

TAX REFORM

   Flat-tax advocates have generated increased publicity for their proposals
and have influenced the municipal market since early 1995. Most of the
discussion on proposed tax-reform measures is based on theoretical concepts,
containing broad assumptions and lacking specific details. Basically, the
various plans raise questions about the fairness of changing from a
progressive tax structure. Low flat-tax rate plans call for the elimination
of deductions of mortgage interest, charitable contributions, property taxes,
and state and local income taxes. Should politicians make tax reform a
central issue in the 1996 elections, media coverage will expand from the
financial page to the front page. If that happens, municipal bonds could come
under further pressure. For example, when major tax reform turmoil occurred
in 1986, municipal yields briefly exceeded taxable yields.

- ------------

*The Bond Buyer Revenue Bond Index is an arithmetic average of the yields of
25 selected municipal revenue bonds with 30-year maturities. Credit ratings
of these bonds range from Aa1 to Baa1 by Moody's Investors Service, Inc., and
AA+ to A- by Standard & Poor's Corp.



         
<PAGE>

   In addition to the market risk associated with the flat-tax proposals,
municipal credits would also be negatively affected. If mortgage interest and
property tax deductions were eliminated, municipalities would experience a
decline in their property tax base. The loss of state and local income tax
deductions would increase the relative economic disadvantage that high tax
states already face. The flat-tax represents an attempt to shift tax
accountability from the federal to local governments. Taxpayer recognition of
the extent of change under consideration may impede the passage of
comprehensive tax reform.

PORTFOLIO STRUCTURE

   The investment objective of a high level of current income exempt from
both federal and state income taxes consistent with preservation of capital
remained the primary consideration in portfolio activity. New investments in
each portfolio of Dean Witter Multi-State Municipal Series Trust have been
focused on investment grade issues rated "A" or better by Moody's Investor
Service, Inc. or Standard & Poor's Corp. Overall average credit quality was
double "A" with the exception of Massachusetts and New York which averaged
single "A." As of November 30, 1995 the Series' average maturities ranged
from 19 to 22 years. Call protection was 7.5 years on average.

   The charts that follow illustrate the growth of a $10,000 investment in
each Series from inception (January 15, 1991 for all Series except Arizona,
which commenced operations on April 30, 1991) through the fiscal year ended
November 30, 1995 versus the performance of similar hypothetical investments
in the issues that comprise the Lehman Brothers Municipal Bond Index.

   For your convenience, we have summarized details regarding the various
individual state Series on the following pages. Here you will find
information on credit quality, maturity, call protection, distributions,
performance and tax-free and taxable equivalent yields for each portfolio.
Please note that the Massachusetts, Michigan, Minnesota, New York and Ohio
Series will continue to have operating expenses in excess of 50 basis points
of daily net assets absorbed by the Investment Manager through December 31,
1996.

LOOKING AHEAD

   The slower pace of economic activity in 1995 and the Federal Reserve
Board's latest interest rate moves have improved bond-market expectations.
The decreasing supply of new issues, combined with significant maturities and
calls for redemptions, should continue to be positive for the municipal
market. However, tax-reduction proposals are likely to continue to receive
publicity and may cloud the outlook for tax-exempt bonds. With long-term
municipal securities yielding more than 90 percent of the yield on U.S.
Treasuries, the market has already begun the process of discounting the risk
that a flat-tax might eventually become law.

   We appreciate your ongoing support of Dean Witter Multi-State Municipal
Series Trust and look forward to continuing to serve your investment needs.

                                               Very truly yours,

                                               /s/ Charles A. Fiumefreddo

DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS November 30, 1995
- -----------------------------------------------------------------------------

1. ORGANIZATION AND ACCOUNTING POLICIES -- Dean Witter Multi-State Municipal
Series Trust (the "Fund") is registered under the Investment Company Act of
1940, as amended (the "Act"), as a non-diversified, open-end management
investment company.

The Fund, organized on October 29, 1990, as a Massachusetts business trust,
is comprised of ten separate Series (the "Series") and commenced operations
as follows:

<TABLE>

                      COMMENCEMENT OF

Pennsylvania .....      January 15, 1991
</TABLE>

The following is a summary of significant accounting policies:

    A. Valuation of Investments -- Portfolio securities are valued for the
    Fund by an outside independent pricing service approved by the Trustees.
    The pricing service has informed the Fund that in valuing the Fund's
    portfolio securities, it uses both a computerized matrix of tax-exempt
    securities and evaluations by its staff, in each case based on information
    concerning market transactions and quotations from dealers which reflect
    the bid side of the market each day. The Fund's portfolio securities are
    thus valued by reference to a combination of transactions and quotations
    for the same or other securities believed to be comparable in quality,
    coupon, maturity, type of issue, call provisions, trading characteristics
    and other features deemed to be relevant. Short-term debt securities
    having a maturity date of more than sixty days at time of purchase are
    valued on a mark-to-market basis until sixty days prior to maturity and
    thereafter at amortized cost based on their value on the 61st day.
    Short-term debt securities having a maturity date of sixty days or less at
    the time of purchase are valued at amortized cost.

    B. Accounting for Investments -- Security transactions are accounted for
    on the trade date (date the order to buy or sell is executed). Realized
    gains and losses on security transactions are determined by the identified
    cost method. Discounts are accreted and premiums are amortized over the
    life of the respective securities. Interest income is accrued daily.

    C. Federal Income Tax Status -- It is the Fund's policy to comply
    individually for each Series with the requirements of the Internal Revenue
    Code applicable to regulated investment companies and to distribute all of
    its taxable and nontaxable income to its shareholders. Accordingly, no
    federal income tax provision is required.

    D. Dividends and Distributions to Shareholders -- The Fund records
    dividends and distributions to its shareholders on the record date. The
    amount of dividends and distributions from net investment income and net
    realized capital gains are determined in accordance with federal income
    tax regulations which may differ from generally accepted accounting
    principles. These "book/tax" differences are either considered temporary
    or permanent in nature. To the extent these differences




         
<PAGE>

DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS November 30, 1995 (continued)
- ----------------------------------------------------------------------------
    are permanent in nature, such amounts are reclassified within the capital
    accounts based on their federal tax-basis treatment; temporary differences
    do not require reclassification. Dividends and distributions which exceed
    net investment income and net realized capital gains for financial
    reporting purposes but not for tax purposes are reported as dividends in
    excess of net investment income or distributions in excess of net realized
    capital gains. To the extent they exceed net investment income and net
    realized capital gains for tax purposes, they are reported as
    distributions of paid-in-capital.

    E. Organizational Expenses -- Dean Witter InterCapital Inc. (the
    "Investment Manager") paid the organizational expenses of the Fund of
    approximately $204,000 of which $150,000 of such expenses ($16,667 for
    each of the initial Series excluding the Arizona Series) have been
    reimbursed. Such expenses have been deferred and are being amortized by
    the straight-line method over a period not to exceed five years from the
    commencement of operations.

    F. Expenses -- Direct expenses are charged to the respective Series and
    general corporate expenses are allocated on the basis of relative net
    assets.

2. INVESTMENT MANAGEMENT AGREEMENT -- Pursuant to an Investment Management
Agreement, each Series of the Fund pays a management fee, accrued daily and
payable monthly, by applying the annual rate of 0.35% to the daily net assets
of each Series determined as of the close of each business day.

   Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes office space and facilities, equipment, clerical,
bookkeeping and certain legal services, and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services,
heat, light, power and other utilities provided to the Fund.

   The Investment Manager has undertaken to waive management fees and assume
all expenses that exceeded 0.50% of the daily net assets with respect to the
Massachusetts, Michigan, Minnesota, New York and Ohio Series through December
31, 1996.

3. PLAN OF DISTRIBUTION -- Dean Witter Distributors Inc. (the "Distributor"),
an affiliate of the Investment Manager, is the distributor of the Fund's
shares and, in accordance with a Plan of Distribution (the "Plan") pursuant
to Rule 12b-1 under the Act, finances certain expenses in connection with the
distribution of shares of the Fund.

   Under the Plan, the Distributor bears the expense of all promotional and
distribution related activities on behalf of the Fund, except for expenses
that the Trustees determined to reimburse, as described below. The following
activities and services may be provided by the Distributor, under the Plan:
(1) compensation to, and expenses of, account executives of Dean Witter
Reynolds Inc., an affiliate of the Investment Manager and Distributor, and
other employees and selected broker-dealers; (2) sales incentives and bonuses
to sales representatives and to marketing personnel in connection with
promoting sales of the Fund's shares; (3) expenses incurred in connection
with promoting sales of the Fund's shares; (4) preparing and distributing
sales literature; and (5) providing advertising and promotional activities,
including direct mail solicitation and television, radio, newspaper, magazine
and other media advertisements.

   The Fund is authorized to reimburse the Distributor for specific expenses
the Distributor incurs or plans to incur in promoting the distribution of the
Fund's shares. The amount of each monthly reimbursement payment may in no
event exceed an amount equal to a payment at the annual rate of 0.15% of each
Series' average daily net assets during the month. Expenses incurred by the
Distributor pursuant to the Plan in any fiscal year will not be reimbursed by
the Fund through payments accrued in any subsequent fiscal year. For the year
ended November 30, 1995, the distribution fees were accrued at the following

DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
- -----------------------------------------------------------------------------

To the Shareholders and Trustees of Dean Witter Multi-State Municipal Series
Trust

In our opinion, the accompanying statements of assets and liabilities,
including the portfolios of investments, and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of the Arizona
Series, the California Series, the Florida Series, the Massachusetts Series,
the Michigan Series, the Minnesota Series, the New Jersey Series, the New
York Series, the Ohio Series and the Pennsylvania Series (constituting the
Dean Witter Multi-State Municipal Series Trust, hereafter referred to as the
"Fund") at November 30, 1995, the results of each of their operations for the
year then ended, the changes in each of their net assets for each of the two
years in the period then ended and the financial highlights for each of the
four years in the period then ended and for the period January 15, 1991
(commencement of operations for all Series except the Arizona Series) and
April 30, 1991 (commencement of operations for the Arizona Series) through
November 30, 1991, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. We believe that our audits,
which included confirmation of securities at November 30, 1995 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
