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

    Fixed-income  market conditions have improved steadily since late last year.
Bonds began to rally in November on signs of slower economic growth in the  wake
of  progressive tightening of monetary policy by the Federal Reserve Board. This
move toward lower long-term  interest rates reversed the  trend of most of  1994
when rapidly rising rates created a severe bear market in bonds.

    Long-term  municipal bond yields, as tracked  by THE BOND BUYER Revenue Bond
Index*, dropped from a high of 7.37  percent in November to 6.00 percent at  the
end  of May. This 137 basis point decline  in yield corresponded to a 13 percent
price increase for  municipal bonds with  30-year maturities. Short-term  yields
have  remained basically  unchanged over  the past  six months.  Thus, the yield
spread or difference between long- and short-term municipal bond interest  rates
narrowed as long rates declined.

    The  seasonal demand pattern for municipals in December more than offset the
uncertainty caused by the Orange County, California bankruptcy filing. During  a
period of scarce supply, the market anticipated cash inflows in January from the
reinvestment of coupons and the proceeds from bond calls and maturities.

    Tax-exempt  bonds  outperformed U.S.  Treasury  bonds through  February. The
ratio of the Revenue Bond  Index yield to the  30-year U.S. Treasury bond  yield
fell from a high of 92 percent in November to 84 percent by the end of February.
A  declining ratio means that municipal bond prices have been stronger than U.S.
Treasury prices.  Tax  reform proposals  advancing  the flat  tax  concept  were
partially  responsible  for  municipals  underperforming  Treasuries  from March
through May. By the end of May, the Revenue Bond Index/Treasury bond yield ratio
had again risen to 91 percent.

    The pace of new-issue underwriting over the first five months of 1995 was 36
percent below the  same period  last year. With  bond maturities  and calls  for
redemption  estimated  to exceed  new  issues coming  to  market this  year, the
outstanding supply of municipal securities is expected to decline. This scarcity
of municipal issues should strengthen market conditions.

    Dean Witter  Multi-State  Municipal  Series  Trust  continued  to  meet  its
investment  objective by  providing shareholders  with a  high level  of current
income exempt from both federal and specific state income taxes, consistent with
preservation of capital.  Cash and  short-term investment  positions averaged  5
percent  at the end of May. An additional  3.5 percent of average net assets was
held in  refunded bonds  escrowed to  call  dates within  10 years.  The  Fund's
weighted  average  maturity ranged  from  18 to  22  years. Call  protection was
maintained at 7.5 years on average. New purchases continued to be of  investment
grade  with quality ratings of  "A" or better, as  measured by Moody's Investors
Service, Inc. or Standard & Poor's Corp. Overall average credit quality remained
"AA," with  the exception  of Massachusetts  and New  York, which  have  average
credit ratings of "A."

- ------------
* 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  and AA+  to A-  by Standard  &
Poor's.

</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,  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. The Fund  amortizes premiums  and accretes  discounts on  securities
    purchased  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  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
<PAGE>
DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------
    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 costs ($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.   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 has  undertaken to waive  management fees and assume
all expenses  that  exceeded 0.50%  of  the daily  net  assets with  respect  to
Massachusetts,  Michigan, Minnesota, New  York and Ohio  Series 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 affiliate 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

the distribution fees were accrued at the following annual rates:
