Over the Long Term -- J. & W. Seligman & Co. Incorporated


TIME IS THE TEST

    In an industry that has changed dramatically in recent years, it's
comforting to know that stability, tradition, and consistent professional
service can still be found in an investment management firm.

    J. & W. Seligman & Co. Incorporated has been providing financial services 
for more than 130 years. From its beginning, Seligman has followed a long-term 
approach to making money for its clients, by managing investment products and 
providing services of the highest quality. Today, Seligman manages the 
Seligman Group of Funds, which offers investors more than 50 investment options.


A PLACE IN HISTORY

    Established in 1864, Seligman played a major role in the geographical
expansion and industrial development of the United States. The firm helped
finance the westward path of the railroads and the building of the Panama Canal.
In the late 1800s and early 1900s, the firm was instrumental in financing the
fledgling automobile and steel industries. Seligman also participated in the
original underwritings for some of the nation's most prominent companies,
including General Motors, Victor Talking Machine, United Artists Theater
Circuit, and Maytag. In 1929, Seligman introduced Tri-Continental Corporation --
which today is the nation's largest diversified closed-end investment company.
In 1930, Seligman began managing its first mutual fund, Broad Street Investing
Co., now known as Seligman Common Stock Fund.


SELIGMAN MUNICIPAL SERIES TRUST

    Seligman Municipal Series Trust, which commenced operations on November 20,
1984, is a series of state-specific municipal bond funds that seek to maximize
income exempt from regular federal income taxes and from personal income taxes
in the applicable state. This is done consistent with the preservation of
capital and with consideration given to opportunities for capital gain by
investing in municipal securities of the designated state, its political
subdivisions, municipalities, and public authorities.

To the Shareholders

   Seligman Municipal Series Trust posted strong results in its fiscal year
ended September 30, 1997. The steady growth of the economy, combined with benign
levels of inflation, reduced yields in the municipal bond market beginning in
May. Bond prices rose, improving the Trust's total returns as it continued to
provide monthly income free from regular income tax. Additional information on
the Trust's investment results begins on page 4.

   Long-term municipal bond yields fluctuated within a narrow range during the
Trust's first quarter and into the early part of 1997. By March, yields began to
rise in response to reports of strong economic growth and in anticipation of a
Federal Reserve Board interest rate increase. After raising the federal funds
rate to 5.50% from 5.25% on March 25, the Fed left rates unchanged. As economic
growth continued without prompting a noticeable increase in inflation, the
municipal bond market rallied from May to July, and then traded within a narrow
range from August to September.

   The yield on the Bond Buyer 20-Bond General Obligation Index, a benchmark for
the municipal market, ended the Trust's fiscal year at 5.36% on September 30,
1997, significantly lower than its 12-month high of 5.88% on April 10, and only
slightly higher than the July 31 low of 5.23%. The yield for the Bond Buyer
20-Bond General Obligation Index stood at 5.76% on September 30, 1996.

   While economic indicators have been mixed recently, the overall tone of the
environment is good. Unemployment levels have remained historically low,
consumer and producer prices have been fairly stable, consumer spending has been
increasing at a reasonable rate, and orders for durable goods - goods that have
a life span of three or more years - have been rising. This economic expansion
has improved the financial well-being of municipalities and increased investor
confidence in the municipal bond market.

   The next few months could be more challenging, given the recent volatility 
in the global equity markets and the business slowdown in Southeast Asia.
Nevertheless, US economic reports remain positive overall. There are still a few
areas where potential inflationary problems persist, particularly in the labor
market. A significant increase in labor costs could prompt the Fed to become
more restrictive and move interest rates up another notch, though this is a
fading risk given recent international events. Nonetheless, the future prospects
of both the municipal bond market and your Trust remain positive. Supply and
demand levels in the municipal market should remain favorable regardless of the
short-term impact of any Fed move.

   We thank you for your continued interest in Seligman Municipal Series Trust,
and look forward to serving your investment needs in the many years to come.

holdings, and financial statements follow this letter.

Interview With Your Portfolio Manager, Thomas G. Moles

Q. What economic factors affected Seligman Municipal Series Trust in the last
   12 months?

A. A healthy economy and a stable rate of inflation would seem the best of all
   possible worlds. However, for much of the past year, the fixed-income markets
   were most heavily influenced by economic growth and whether or not inflation
   was an important risk factor. The longer the economic expansion endured, the
   more anxious some market participants became that rising inflation was just 
   around the corner. The strong employment picture was of particular concern. 
   While low unemployment resulted in scattered labor shortages, it did not 
   translate into meaningfully higher wages. To date, wage pressures continue 
   to be restrained, mainly due to productivity improvements and global 
   competition. The market's reluctance to accept the premise that economic 
   vigor and low inflation are not mutually exclusive has prevented long-term 
   interest rates from falling to levels that would better reflect this 
   remarkable economic environment.

Q. What market factors affected Seligman Municipal Series Trust in the last 
   12 months?

A. Seligman Municipal Series Trust ended its fiscal year on a positive note.
   During the past 12 months, long-term municipal yields, as measured by the
   Bond Buyer 20-Bond General Obligation Index, fluctuated within a narrow
   trading range. At September 30, 1997, yields were almost a half-point lower
   than at the beginning of the Trust's fiscal year. The declining interest
   rate environment led to rising prices for the majority of the holdings and
   favorable performance results for each Series.

     Investor demand for municipal securities generally kept pace with supply,
   contributing to the relative stability of the municipal bond market. While
   new issue volume has increased modestly over the past several years, it has
   had a negligible impact on the total outstanding supply of municipal bonds
   due to a record number of bond calls and redemptions.

     Additionally, the extraordinary economic expansion, now in its seventh 
   year, continued to improve credit trends for the nation's states, cities, and
   municipalities. Year-to-date, credit rating upgrades significantly
   outnumbered rating downgrades. Within Seligman Municipal Series Trust, the
   overall credit quality of the portfolios improved as several of our holdings
   received upgraded ratings.

Q. What was your investment strategy?

A. Consistent with our positive long-term interest rate outlook, new purchases
   were concentrated in longer maturity bonds. Generally, for a parallel
   decline in yields, long-term bonds appreciate more in price than
   shorter-term bonds. Long-term bonds also offer significantly higher yields
   than shorter-term bonds, allowing us to improve the Trust's yields. Further,
   given the market's short-term volatility, we sought to lessen the impact
   of temporary interest rate increases on the Trust's net asset values
   without sacrificing future upside potential. To do

Interview With Your Portfolio Manager, Thomas G. Moles

   this, we elected to purchase mostly current coupon bonds (bonds with coupon
   rates at or near current market rates). Current coupon bonds are 
   intrinsically less sensitive to changes in interest rates than lower coupon
   bonds of the same maturity.

     As each Series matures, older, callable portfolio holdings are approaching
   their optional call dates, resulting in increased reinvestment risk.
   (Callable bonds are bonds that are redeemable on specified dates and at
   specified prices -- prior to maturity -- at the option of the issuer.) In
   general, an open-end fund's income distributions will, over time, move
   toward current market levels as a result of portfolio activity, shareholder
   transactions, and bond calls and redemptions. In the past year, we focused
   on improving the Trust's call protection by selling shorter-call bonds and
   replacing them with longer-call bonds, while attempting to minimize the
   impact on income distributions.

Q. What is the outlook?

A. While fixed-income market participants remain cautious, economic fundamentals
   point to a continuation of steady, moderate growth with low inflation. We,
   therefore, remain optimistic regarding the long-term prospects of the Trust.
   Stable long-term interest rates, improving credit trends, and attractive
   real rates of return bode well for the performance of the municipal bond
   market going forward. We believe municipal bond funds will continue to play
   an important role in helping investors meet their investment goals. At
   Seligman, we have a straightforward approach to managing municipal bond
   funds. We invest for the long term, building diversified portfolios of
   quality bonds, and always work to provide our shareholders with competitive
   investment returns.

                                                                              3

- -------------------
   * Return figures reflect any change in price and assume all distributions
     within the period are invested in additional shares. Returns for Class A
     shares are calculated with and without the effect of the initial 4.75%
     maximum sales charge. Returns for Class D shares are calculated with and
     without the effect of the 1% contingent deferred sales load ("CDSL"),
     charged only on redemptions made within one year of the date of purchase.
     No adjustment was made to the performance of Class A shares for periods
     prior to commencement dates December 27, 1990, in the case of the Florida
     Series, and January 1, 1993, in the case of the California High-Yield and
     California Quality Series, for the annual Administration, Shareholder
     Services and Distribution Plan fee of up to 0.25% of average daily net
     assets for each Series. The rates of return will vary and the principal
     value of an investment will fluctuate. Shares, if redeemed, may be worth
     more or less than their original cost. A portion of each Series' income may
     be subject to applicable state and local taxes, and any amount may be
     subject to the federal alternative minimum tax.
     Past performance is not indicative of future investment results.
  ** The Lehman Index is an unmanaged index that does not include any fees or
     sales charges and does not reflect state-specific bond market performance.
     Investors cannot invest directly in an index.
 *** At its discretion, the Manager waived all or a portion of its fees and, in
     some cases, reimbursed certain expenses for the North Carolina Series. This
     has the effect of increasing the Series' average annual total returns for
     the since-inception period.

Notes to Financial Statements

1. Multiple Classes of Shares -- Seligman Municipal Series Trust (the "Trust")
consists of four separate series: the "California High-Yield Series," the
"California Quality Series," the "Florida Series," and the "North Carolina
Series." Each Series of the Trust offers two classes of shares. All shares
existing prior to February 1, 1994, the commencement date of Class D shares,
were classified as Class A shares. Class A shares are sold with an initial sales
charge of up to 4.75% and a continuing service fee of up to 0.25% on an annual
basis. Class A shares purchased in an amount of $1,000,000 or more are sold
without an initial sales charge but are subject to a contingent deferred sales
load ("CDSL") of 1% on redemptions within 18 months of purchase. Class D shares
are sold without an initial sales charge but are subject to a distribution fee
of up to 0.75% and a service fee of up to 0.25% on an annual basis, and a CDSL
of 1% imposed on redemptions made within one year of purchase. The two classes
of shares for each Series represent interests in the same portfolio of
investments, have the same rights and are generally identical in all respects
except that each class bears its separate distribution and certain other class
expenses, and has exclusive voting rights with respect to any matter on which a
separate vote of any class is required.

2. Significant Accounting Policies -- The financial statements have been
prepared in conformity with generally accepted accounting principles which
require management to make certain estimates and assumptions at the date of the
financial statements. The following summarizes the significant accounting
policies of the Trust:

a.  Security Valuation -- All municipal securities and other short-term holdings
    maturing in more than 60 days are valued based upon quotations provided by
    an independent pricing service or, in their absence, at fair value
    determined in accordance with procedures approved by the Trustees.
    Short-term holdings maturing in 60 days or less are generally valued at
    amortized cost.

b.  Federal Taxes -- There is no provision for federal income tax. Each Series
    has elected to be taxed as a regulated investment company and intends to
    distribute substantially all taxable net income and net gain realized.

c.  Security Transactions and Related Investment Income -- Investment
    transactions are recorded on trade dates. Identified cost of investments
    sold is used for both financial statement and federal income tax purposes.
    Interest income is recorded on the accrual basis. The Trust amortizes
    original issue discounts and premiums paid on purchases of portfolio
    securities. Discounts other than original
    issue discounts are not amortized.

d.  Multiple Class Allocations -- All income, expenses (other than
    class-specific expenses), and realized and unrealized gains or losses are
    allocated daily to each class of shares based upon the relative value of the
    shares of each class. Class-specific expenses, which include distribution
    and service fees and any other items that are specifically attributable to
    a particular class, are charged directly to such class. For the year ended
    September 30, 1997, distribution and service fees were the only
    class-specific expenses.

e.  Distributions to Shareholders -- Dividends are declared daily and paid
    monthly. Other distributions paid by the Trust are recorded on the
    ex-dividend date. The treatment for financial statement purposes of
    distributions made to shareholders during the year from net investment
    income or net realized gains may differ from their ultimate treatment for
    federal income tax purposes. These differences are caused primarily by
    differences in the timing of the recognition of certain components of
    income, expense, or realized capital gain for federal income tax purposes.
    Where such differences are permanent in nature, they are reclassified in the
    components of net assets based on their ultimate characterization for
    federal income tax purposes. Any such reclassifications will have no effect
    on net assets, results of operations, or net asset value per share of any
    series of the Trust.

3. Purchases and Sales of Securities -- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended September 30,
1997, were as follows:

  SERIES                    PURCHASES                SALES
- ----------                ------------           ------------

California Quality          10,963,840              20,983,040
Florida                     15,089,050              18,279,160
North Carolina               4,549,405              10,481,680

    At September 30, 1997, the cost of investments for federal income tax
purposes was substantially the same as the cost for financial reporting
purposes, and the tax basis gross unrealized appreciation and depreciation of
portfolio securities were as follows:

                               TOTAL                  TOTAL
                            UNREALIZED             UNREALIZED
  SERIES                   APPRECIATION           DEPRECIATION

California High-Yield       $3,078,058              $30,918
California Quality           5,958,601               30,570
Florida                      1,668,548               82,555

such fees to the Trust pursuant to the Plan. For the year ended September 30,
1997, for the California High-Yield, California Quality, Florida, and North

Class D shares occurring within one year of purchase and on certain redemptions

Financial Highlights

   The Trust's financial highlights are presented below. "Per share operating
performance" data is designed to allow investors to trace the operating
performance of each Class, on a per share basis, from the beginning net asset
value to the ending net asset value, so that investors can understand what
effect the individual items have on their investment, assuming it was held
throughout the period. Generally, per share amounts are derived by converting
the actual dollar amounts incurred for each item, as disclosed in the financial
statements, to their equivalent per share amounts, based on average shares
outstanding.

   "Total return based on net asset value" measures each Class's performance
assuming that investors purchased shares at net asset value as of the beginning
of the period, invested dividends and capital gains paid at net asset value, and
then sold their shares at the net asset value on the last day of the period. The
total return computations do not reflect any sales charges investors may incur
in purchasing or selling shares of each Series. Total returns for periods of
less than one year are not annualized.

Report of Independent Auditors

The Trustees and Shareholders,
Seligman Municipal Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the California High-Yield, California Quality,
Florida, and North Carolina Series of Seligman Municipal Series Trust, as of
September 30, 1997, the related statements of operations for the year then ended
and of changes in net assets for each of the years in the two-year period then
ended, and the financial highlights for each of the periods presented. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.

Our procedures included confirmation of securities owned as of September 30,
1997 by correspondence with the Trust's custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the California
High-Yield, California Quality, Florida, and North Carolina Series of Seligman
Municipal Series Trust as of September 30, 1997, the results of their
operations, the changes in their net assets, and the financial highlights for
the respective stated periods, in conformity with generally accepted accounting
principles.

Glossary of Financial Terms

CAPITAL GAIN DISTRIBUTION -- A payment to mutual fund shareholders of profits
realized on the sale of securities in a fund's portfolio. For tax purposes,
these profits may be considered short-, mid-, or long-term capital gains and may
be taxed at different rates.

CAPITAL APPRECIATION/DEPRECIATION -- An increase or decrease in the market value
of a mutual fund's portfolio securities, which is reflected in the net asset
value of the fund's shares. Capital appreciation/depreciation of an individual
security is in relation to the original purchase price.

COMPOUNDING -- The change in the value of an investment as shareholders receive
earnings on their investment's earnings. For example, if $1,000 is invested at a
fixed rate of 7% a year, the initial investment is worth $1,070 after one year.
If the return is compounded, second year earnings will be based not on the
original $1,000, but on the $1,070, which includes the first year's earnings.

CONTINGENT DEFERRED SALES LOAD (CDSL) -- Depending on the class of shares owned,
a fee charged by a mutual fund when shares are sold back to the fund (the CDSL
expires after a fixed time period).

DIVIDEND -- A payment by a mutual fund, usually derived from the fund's net
investment income (dividends and interest less expenses).

DIVIDEND YIELD -- A measurement of a fund's dividend as a percentage of the
maximum offering price.

EXPENSE RATIO -- The cost of doing business for a mutual fund, expressed as a
percent of the fund's net assets.

INVESTMENT OBJECTIVE -- The shared investment goal of a fund and its
shareholders.

MANAGEMENT FEE -- The amount paid by a mutual fund to its investment advisor(s).

MULTIPLE CLASSES OF SHARES -- Although an individual mutual fund invests in only
one portfolio of securities, it may offer investors several purchase options
which are "classes" of shares. Multiple classes permit shareholders to choose
the fee structure that best meets their needs and goals. Generally, each class
will differ in terms of how and when sales charges and certain fees are
assessed.

NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC. (NASD) -- A self-regulatory
body with authority over firms that distribute mutual funds.

NET ASSET VALUE (NAV) PER SHARE -- The market worth of one fund share, obtained
by adding a mutual fund's total assets (securities, cash, and any accrued
earnings), subtracting liabilities, and dividing the resulting net assets by the
number of shares outstanding.

OFFERING PRICE (OP) -- The price at which a mutual fund's share can be
purchased. The offering price per share is the current net asset value plus any
sales charge.

PORTFOLIO TURNOVER -- A measure of the trading activity in a mutual fund's
investment portfolio that reflects how often securities are bought and sold.

PROSPECTUS -- The legal document describing a mutual fund to all prospective
shareholders. It contains information required by the Securities and Exchange
Commission (SEC), such as a fund's investment objective and policies, services,
investment restrictions, officers and directors, how shares are bought and
redeemed, fund fees and other charges, and the fund's financial statements.

SEC YIELD -- SEC Yield refers to the net income earned by a fund during a recent
30-day period. This income is annualized and then divided by the maximum
offering price per share on the last day of the 30-day period. The SEC Yield
formula reflects semiannual compounding.

SECURITIES AND EXCHANGE COMMISSION -- The primary US federal agency that
regulates the registration and distribution of mutual fund shares.

STATEMENT OF ADDITIONAL INFORMATION -- Document that contains updated or more
detailed information about a mutual fund and supplements the prospectus. It is
available at no charge upon request.

TOTAL RETURN -- A measure of a fund's performance encompassing all elements of
return. Reflects the change in share price over a given period and assumes all
distributions are taken in additional fund shares. The Average Annual Total
Return represents the average annual compounded rate of return for the periods

interest, divided by the purchase price. For stocks, the yield is measured by
dividing dividends paid by the market price of the stock.
