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

   Strong economic growth in the fourth quarter of 1993 and a shift in
Federal Reserve Board monetary policy in February of 1994 led to the sharpest
increase in interest rates in more than six years. At the beginning of the
year, concerns regarding inflation developed as the economy approached full
employment and commodity prices moved upward. The Federal Reserve Board
responded by tightening monetary policy. Since early February, the central
bank has raised the federal-funds rate--the interest rate banks charge each
other for overnight loans--250 basis points from 3.00% to 5.50% in six
separate moves through November. Between May and November, the discount
rate--the interest rate the Federal Reserve charges member banks for
loans--increased 175 basis points to 4.75%.

   In February and March, yields, as measured by The Bond Buyer Revenue Bond
Index,* jumped 89 basis points from 5.50% to 6.39% in response to the Federal
Reserve Board's initial tightening and subsequent municipal bond selling
pressure. Despite 15 to 20 basis point swings in April and May, a semblance
of stability returned to the market between June and August. After Labor Day,
however, continued economic growth, aggressive tax-loss selling, heavy
mutual-fund redemptions and excessive dealer inventory led to further
municipal market deterioration. Over the 12-month period ended November 30,
1994, Revenue Bond Index yields rose from 5.71% to 7.18%. This total yield
increase of 147 basis points was equivalent to a 17% price decline for a
municipal bond with a 30-year maturity. Half of the price decline occurred
between September and November.

   The municipal market was also influenced by supply and demand conditions.
New-issue underwriting totaled a record $290 billion in 1993. The pace of
new-issue activity through November 1994, however, slowed 43%. The estimated
issuance for 1994 is $160 billion. By way of comparison, bond maturities and
calls for redemption are expected to reach $190 billion this year, resulting
in a reduction in the amount of municipal debt outstanding. This scarcity
would normally be expected to improve the relative performance of municipal
bonds under a stable-to-improving market environment.

INVESTMENT STRATEGY

   The investment objective of providing shareholders with a high level of
current income exempt from both federal and specific state income taxes
consistent with preservation of capital remained the primary consideration in
portfolio activity. However, the dramatic rise in interest rates since
February 1994 caused the Series' portfolios to become more defensive. The
short-term investment positions were increased from an average of 3% to 10%
by the end of November. The Series' weighted average maturities ranged from
19 to 21 years. Call protection was 8 years on average. Average credit
quality ratings were double A, except for Massachusetts and New York which
were single A.

   For your convenience, we have summarized details regarding the various
Series on the following pages. Here you will find information on credit
quality, maturity, call protection, distributions, performance and tax-free
and taxable yields for each portfolio.

   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, 1994, versus the performance of a similar investment in the
Lehman Brothers Municipal Bond Index.

   Please note that the Massachusetts, Michigan, Minnesota, New York and Ohio
Series will continue to have expenses (except for 12b-1 fees) in excess of 50
basis points of daily net assets absorbed by Dean Witter InterCapital Inc.
through December 31, 1995.

   On December 6, 1994 Orange County, California filed for protection under
federal bankruptcy law as the result of market losses in its pooled
investment fund. None of the California Series' holdings have been identified
as participants in the Orange County pool.

   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,
                                                       Charles A. Fiumefreddo

NOTES TO FINANICAL STATEMENTS

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>

</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 Fund's Trustees. The
pricing service has informed the Fund that in valuing the Fund's portfolio
securities each day, it uses both a computerized matrix of tax-exempt
securities and evaluations by its staff, in each case based on available
information concerning market transactions and quotations from dealers which
reflect the bid side of the market. 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 on the identified cost
method. Interest income is accrued daily. Premiums and discounts on
securities are amortized over the life of the respective securities.

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 are permanent in nature, such amounts
are reclassified within the capital accounts based on their




         
<PAGE>

DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS (continued)
- - -----------------------------------------------------------------------------

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 the Fund has agreed to bear and reimburse the Investment
Manager for $150,000 of such costs ($16,667 for each of the initial Series
excluding the Arizona Series). Such reimbursed 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. TRANSACTIONS WITH THE INVESTMENT MANAGER --Pursuant to an Investment
Management Agreement, each Series of the Fund pays its Investment Manager 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 had undertaken to waive management fees and assume
all expenses that exceeded 0.50% of the daily net assets with respect to each
Series of the Fund through December 31, 1993 and with respect to
Massachusetts, Michigan, Minnesota, New York and Ohio has undertaken to
extend such expense limitation for the period January 1, 1994 through
December 31, 1995.

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 affilate of the Investment Manager and Distributor, and
other 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 the
Fund's 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, 1994, the distribution fees were accrued at the following
annual rates:

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, 1994, 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
three 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 owned at November 30, 1994 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.
