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

   We are pleased to present the annual report on the operations of Dean 
Witter Multi-State Series Trust for the November 30, 1996 fiscal year. 

   Stronger economic growth and the potential threat of rising inflation 
shifted the tone of the fixed-income markets from bullish to bearish early in 
1996. This change in market psychology was confirmed in March by a 
surprisingly large increase in payroll employment. The rise in interest rates 
between February and July may be attributed to market weakness on the days 
that strong monthly employment figures were reported. The bond market 
sporadically pushed long-term yields higher, in anticipation of a possible 
increase in the federal-funds rate by the Federal Reserve Board. However, as 
employment growth and overall economic activity slowed during the summer, the 
central bank left monetary policy unchanged. As a result, the fixed-income 
markets regained an optimistic outlook and rallied from September through 
November to lower yields last seen at the beginning of the year. 

MUNICIPAL MARKET CONDITIONS 

   Between February and July 1996, 30-year insured revenue bond yields rose 
75 basis points from 5.40 percent to reach 6.15 percent in April and again in 
mid-June. Subsequently, demand for municipal bonds improved and followed the 
trend of Treasuries to lower rates. By the end of November, insured bond 
yields stood at 5.50 percent. In November, the yield curve pickup for 
extending maturities from 1 to 30 years was 190 basis points. 

   The ratio of insured revenue bond yields to 30-year U.S. Treasury yields 
moved from 92 percent to 86 percent for the calendar year to date. A 
declining ratio means that municipal bond prices outperformed U.S. Treasury 
prices. The relative improvement in municipals occurred as flat-tax proposals 
failed to gain public support. 

   The municipal market also benefited from steady demand. In addition to 
regular maturities and calls for redemption this year, it has been estimated 
that investors also faced the retirement of over $60 billion in debt that had 
been previously refinanced. On the supply side, new issues increased 13 
percent to $160 billion for the first 11 months of 1996. 

PORTFOLIO STRUCTURE 

   Over the course of the fiscal year ended November 30, 1996, the average 
cash and short-term investment position of Dean Witter Multi-State Municipal 
Series Trust was increased to 7 percent of net assets. An additional 6 
percent of average net assets were held in refunded bonds escrowed to call 
dates within 10 years. The Fund's weighted average maturities ranged from 17 
to 20 years. Call protection was 6.5 years on average. Overall average credit 
quality remained double "A". 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.

   For your convenience, we have summarized details regarding the various 
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. 

LOOKING AHEAD 

   The balance between the supply of new issues and demand created by 
maturities is expected to remain positive for the municipal market. Long-term 
insured municipal securities currently yield 86 percent of the yield on U.S. 
Treasury securities and may be expected to move in tandem with the Treasury 
market. Although municipal performance relative to Treasuries has improved, 
tax-exempt investments could again be affected by market uncertainty if new 
tax-reduction proposals resurface. 

   We appreciate your ongoing support of Dean Witter Multi-State 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, 1996 
- ----------------------------------------------------------------------------- 
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 investment objective of each Series is to provide a 
high level of current income exempt from both Federal and the designated 
state income taxes consistent with preservation of capital. 

The Fund, organized on October 29, 1990, as a Massachusetts business trust, 
is comprised of ten separate Series (the "Series"); 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. Each of the Series commenced 
operations on January 15, 1991, with the exception of the Arizona Series 
which commenced operations on April 30, 1991. 

The preparation of financial statements in accordance with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts and disclosures. Actual results could differ 
from those estimates. 

The following is a summary of significant accounting policies: 

    A. Valuation of Investments -- Portfolio securities are valued by an 
    outside independent pricing service approved by the Fund's Trustees. The 
    pricing service has informed the Fund that in valuing the 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 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, 1996 (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 were deferred and fully amortized as of January 
    14, 1996. 

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

2. INVESTMENT MANAGEMENT AGREEMENT -- Pursuant to an Investment Management 
Agreement, each Series of the Fund pays the 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 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, 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 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, 1996, 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, 1996, 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 
five 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, 1996 by 
correspondence with the custodian and brokers, provide a reasonable basis for 
the opinion expressed above.
