SELIGMAN--TIMES CHANGE...VALUES ENDURE

J. & W.  SELIGMAN  & CO.  INCORPORATED  IS A  FIRM  WITH  A  LONG  TRADITION  OF
INVESTMENT  EXPERTISE,  OFFERING  A BROAD  ARRAY OF  INVESTMENT  CHOICES TO HELP
TODAY'S INVESTORS SEEK THEIR LONG-TERM FINANCIAL GOALS.

TIMES CHANGE...

Established in 1864, Seligman's history of providing financial services has been
marked not by fanfare, but rather by a quiet and firm adherence to financial
prudence. While the world has changed dramatically in the 134 years since
Seligman first opened its doors, the firm has continued to offer its clients
high-quality investment solutions through changing times.

In the late 19th century, as the country grew, Seligman helped finance the
westward expansion of the railroads, the construction of the Panama Canal, and
the launching of urban transit systems. In the first part of the 20th century,
as America became an industrial power, the firm helped fund the growing capital
needs of the nascent automobile and steel industries.

With the formation of Tri-Continental Corporation in 1929 -- today, the nation's
largest diversified publicly-traded closed-end investment company -- Seligman
began shifting its emphasis from investment banking to investment management.
Despite the stock market crash and ensuing depression, Seligman was convinced of
the importance that investment companies could have in building wealth for
individual investors and launched its first mutual fund in 1930.

In the decades that followed, Seligman has continued to offer forward-looking
investment solutions, including funds that focus on technology stocks, municipal
bonds, and international securities.

 ...VALUES ENDURE

Seligman is proud of its distinctive past and of the traditional values that
continue to shape the firm's business decisions and investment judgment. While
much has changed over the years, the firm's commitment to providing prudent
investment management that seeks to build wealth for clients over time is an
enduring value that will guide Seligman into the new millennium.

TO THE SHAREHOLDERS

Seligman Municipal Fund Series posted strong results for its fiscal year ended
September 30, 1998. Although the growth of the US economy slowed from its record
pace, the expansion continued. Inflation and interest rates reached their lowest
levels in a quarter century, and unemployment was at its lowest level since
1970.

Despite ongoing strength in the US, economic turmoil spread throughout the rest
of the world. The Asian financial crisis worsened, Japan failed to resolve its
banking problems, Russia's economy became chaotic, and economic crises loomed
throughout much of Latin America, particularly in Brazil. Fears of risk in
nearly all types of financial assets drove investors out of the equity markets
and into the relative safety and quality of investments such as US Treasury
bonds, often a haven from a turbulent stock market. This "flight to quality"
helped create a more attractive environment for municipal bonds.

Major factors influencing the market for municipal bonds over the year were the
prolonged Treasury bond rally and heavy issuance of municipal securities.
Municipal bond holders fared well as interest rates generally declined over this
time period. Nonetheless, the performance of the municipal market lagged that of
the Treasury bond market, as investors focused on quality because of concerns
about financial instability. Treasury bond prices rose sharply over the 12-month
period, sending yields significantly lower. At one point in the period, selected
municipal obligations traded at the same yield as Treasuries, even though
municipals offered more favorable tax treatment. Currently, long-term municipal
bonds have not been this attractive, relative to long-term Treasuries, since
1986, when proposed legislation threatened the tax-exempt status of municipal
securities.

Looking ahead, we see the favorable climate for municipal bonds continuing. Low
inflation and a growing economy should serve to protect the value of municipal
investments. Fewer new issues may be entering the market, which could tighten
the supply/demand balance. This could improve overall total rate-of-return
prospects. Also, although the US economy continues to grow, this growth is
slowing, and the global situation is forcing the Federal Reserve into a more
benign strategy on interest rates. The Fed has already cut short-term rates
twice, and we expect more cuts until a semblance of international stability
emerges. Finally, the municipal market's record of safety and stability offers
further appeal to investors in these more troubled times, especially as equity
market volatility continues.

All in all, we feel the investment attractiveness of municipals remains
compelling. In this period of global economic uncertainty and low interest
rates, municipals are an appropriate alternative for those investors with
suitable investment requirements.

As you may know, companies are modifying their computer systems to recognize
dates of January 1, 2000, and beyond. This is often referred to as the "Y2K"
problem. Unless systems are updated, many applications may interpret the last
two digits of the year to mean 1900 instead of 2000. J. & W. Seligman & Co.
Incorporated, the Seligman Investment Companies, and Seligman Data Corp., your
shareholder service agent, have jointly established a team to ensure that your
investment and shareholder services are not disrupted. This team is supported by
consulting firms specializing in Y2K solutions. Substantial work has been
performed to date, and we are confident that when our plans are finalized and
all systems are tested, there will be no disruption in the services provided by
your Fund.

Thank you for your continued support of Seligman Municipal Fund Series. We look
forward to serving your investment needs in the many years to come. A discussion

INTERVIEW WITH YOUR PORTFOLIO MANAGER


Q.  WHAT ECONOMIC FACTORS INFLUENCED SELIGMAN MUNICIPAL FUND SERIES IN THE  LAST
    12 MONTHS?

A.  The continuing combination of low inflation, low unemployment, and steady
    economic growth throughout the past 12 months sustained what became one of
    the nation's longest peacetime economic expansions. This contributed to the
    overall improvement of the financial condition of America's states, cities,
    and municipalities. Over the past year, credit rating upgrades significantly
    outnumbered rating downgrades. These upgrades enhanced the overall
    creditworthiness of the municipal marketplace.

    But, by the end of the fiscal year, there was widespread expectation that
    the US may be unable to avoid the economic slowdown that has already gripped
    much of the world. While many economists were calling a recession unlikely,
    the fact that they were including its potential in their forecasts implied
    that the ongoing domestic economic expansion would not continue. In the
    final months of the fiscal year, turmoil in world markets began to
    contribute to a modest slowdown in the pace of US economic growth, and
    prevented an acceleration in the rate of inflation. In September, the
    Federal Reserve Board lowered the federal funds rate by one-quarter of one
    percent. With a warning that growing fear among investors and lenders was
    threatening the nation's economic expansion, the Fed unexpectedly cut
    interest rates again in October, the first time in four and a half years
    that the central bank had changed interest-rate policy outside one of its
    normally scheduled meetings. This unusual timing suggested that the Fed
    believed that the domestic economy is beginning to deteriorate as the
    worldwide financial crisis gains momentum, and that a credit shortage may be
    developing that could further curb growth. Fed officials have hinted that
    more interest-rate reductions will ensue if the global financial turmoil
    escalates. Declining US equity markets reflected these fears, as investors
    sold stocks in favor of the relative safety and quality of US Treasury
    bonds, which are often considered a haven from a volatile stock market.

Q.  WHAT MARKET FACTORS INFLUENCED SELIGMAN MUNICIPAL FUND SERIES IN THE LAST 12
    MONTHS?

A.  Overall, Seligman Municipal Fund Series ended its fiscal year on a positive
    note. During the period, long-term municipal yields fluctuated within a
    narrow range, decreasing by almost one-half of a point. The declining
    interest-rate environment led to rising prices for the majority of holdings
    and competitive performance results for each Series' net asset value.

INTERVIEW WITH YOUR PORTFOLIO MANAGER
THOMAS G. MOLES

    However, the municipal market underperformed the US Treasury market during
    the 12-month period. The ongoing strength in the economy over the year
    caused the supply of Treasury bonds to shrink, as the federal government
    needed to borrow less after running its first budget surplus in 29 years.
    But, the solid economy and low interest rates caused the supply of municipal
    bonds to grow. The net reduction in Treasury financing and the increasing
    municipal bond issuance was compounded by the increased investor demand for
    Treasuries. These factors caused the decline in Treasury yields to
    significantly outpace the drop in municipal yields. Because of these
    factors, long-term municipal bonds have not been as attractive, relative to
    long-term Treasuries, since 1986, when proposed tax legislation threatened
    the tax-exempt status of municipal securities.

Q.  WHAT WAS YOUR INVESTMENT STRATEGY?

A.  Throughout the 12-month period, the long-term interest rate outlook was
    positive, and Seligman Municipal Fund Series was positioned to benefit from
    the declining interest-rate environment. The Seligman Municipals Team
    engaged in duration-extension trades, selling shorter-term holdings and
    replacing them with long-term, current-coupon bonds. Current-coupon bonds
    have coupon rates that are at or near current market rates. Generally, when
    long-term bond yields decline, the prices appreciate more than those of
    shorter-term bonds.

    During the past 12 months, we also improved the call protection of the
    portfolios. As the bonds within the portfolio mature, older holdings
    approach their optional call dates (a callable bond can be redeemed by the
    issuer, prior to maturity, on specified dates and at predetermined prices).
    Declining interest rates increase the risk that these bonds will be called
    by the issuer. The lower interest-rate environment over the 12-month period
    prompted many municipal issuers to retire outstanding, higher-coupon debt.
    Additionally, as a direct result of the significant increase in refunding
    volume, many of the portfolio's holdings were advance-refunded, which had a
    positive impact on performance. In general, when a municipal bond is
    refunded, total return performance is improved, and the bond's rating is
    often upgraded.

Q.  WHAT IS YOUR OUTLOOK?

A.  Long-term municipal yields have fallen to levels not seen in many years.
    Municipal securities continue to offer a significant yield advantage
    compared to the after-tax returns of other fixed-income investments.
    Further, as the yield spread between municipal and Treasury bonds
    normalizes, municipal market performance should improve, relative to the
    Treasury market. Finally, the municipal market's record of safety and
    stability may become more appealing as volatility persists in the US equity
    markets. Consequently, we remain optimistic about the long-term prospects
    for the municipal bond market, and for Seligman Municipal Fund Series.

   * Returns for periods of less than one year are not annualized.
  ** 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 charge ("CDSC"),
     charged on redemptions made within one year of the date after purchase. No
     adjustment was made to the performance of Class A shares for periods prior
     to January 1, 1993, the commencement date for the annual Administration,
     Shareholder Services and Distribution Plan fee of up to 0.25% of average
     daily net assets. 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.

NOTES TO FINANCIAL STATEMENTS

1. MULTIPLE CLASSES OF SHARES -- Seligman Municipal Fund Series, Inc. (the
"Fund") consists of 13 separate series: the "National Series," the "Colorado
Series," the "Georgia Series," the "Louisiana Series," the "Maryland Series,"
the "Massachusetts Series," the "Michigan Series," the "Minnesota Series," the
"Missouri Series," the "New York Series," the "Ohio Series," the "Oregon
Series," and the "South Carolina Series." Each Series of the Fund offers two
classes of 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 charge ("CDSC") 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 CDSC 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 Fund:

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 Board of Directors. 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 Fund 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, 1998,
   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 Fund 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
   reclassification will have no effect on net assets, results of operations, or
   net asset value per share of the Fund.

3. PURCHASES AND SALES OF SECURITIES -- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended September 30,
1998, were as follows:

   SERIES                  PURCHASES                 SALES

5. COMMITTED LINE OF CREDIT -- Effective July 1, 1998, the Fund entered into a
joint $800 million committed line of credit that is shared by substantially all
funds in the Seligman Group of Investment Companies. Each Series' borrowings are
limited to 10% of its net assets. Borrowings pursuant to the credit facility are
subject to interest at a rate equal to the overnight federal funds rate plus
0.50% on an overnight basis. Each Series incurs a commitment fee of 0.08% per
annum on its share of the unused portion of the credit facility. The credit
facility may be drawn upon only for temporary purposes and is subject to certain
other customary restrictions. The credit facility commitment expires one year
from the date of the agreement but is renewable with the consent of the
participating banks. To date, the Fund has not borrowed from the credit
facility.

6. LOSS CARRYFORWARD -- In accordance with current federal income tax law, each
of the Series' net realized capital gains and losses are considered separately
for purposes of determining taxable capital gains on an annual basis. At
September 30, 1998, the net loss carryforwards for the National and Colorado
Series amounted to $1,559,215 and $115,843, respectively, which are available
for offset against future taxable net gains, expiring in various amounts through
2005. Accordingly, no capital gain distributions are expected to be paid to
shareholders of the National and Colorado Series until net capital gains have
been realized in excess of the available capital loss carryforwards.

FINANCIAL HIGHLIGHTS

   The Fund'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 BOARD OF DIRECTORS AND SHAREHOLDERS,
SELIGMAN MUNICIPAL FUND SERIES, INC.:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the National, Colorado, Georgia, Louisiana,
Maryland, Massachusetts, Michigan, Minnesota, Missouri, New York, Ohio, Oregon,
and South Carolina Series of Seligman Municipal Fund Series, Inc. as of
September 30, 1998, 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
Fund'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, 1998 by correspondence with the Fund'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 each Series of
Seligman Municipal Fund Series, Inc. as of September 30, 1998, 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 taxed at different rates, primarily depending upon the
length of time the securities were owned by the fund.

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 not be based on the
original $1,000, but on the $1,070, which includes the first year's earnings.

CONTINGENT DEFERRED SALES CHARGE (CDSC) -- Depending on the class of shares
owned, a fee charged by a mutual fund when shares are sold back to the fund (the
CDSC 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 -- A document that contains updated or more
detailed information about an investment company and that 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
presented.

YIELD ON SECURITIES -- For bonds, the current yield is the coupon rate of
interest, divided by the purchase price. For stocks, the yield is measured by
dividing dividends paid by the market price of the stock.
