JAMES, JESSE, AND JOSEPH SELIGMAN, 1870


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 has a history of providing financial services
marked not by fanfare, but rather by a quiet and firm adherence to financial
prudence. While the world has changed dramatically in the 135 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 began managing its first mutual fund in 1930.

In the decades that followed, Seligman has continued to offer forward-looking
investment solutions, including equity funds that specialize in small companies,
technology, or international securities, and bond funds that focus on high-yield
issuers, US government bonds, or municipal 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

During Seligman Municipal Fund Series' six-month reporting period ended March
31, 1999, the US economy remained strong. In fact, the economy grew faster than
almost anyone had predicted.

At the Fund's fiscal year-end in September 1998, the consensus was that the US
economy would slow, possibly to recessionary levels, in the face of worldwide
financial disorder brought on by the Asian economic crisis. However, US consumer
strength was widely underestimated, and consumer confidence and the strong
consumer demand that accompanied it remained a powerful economic force. Not only
did the economy continue to surprise on the upside, it did so without signs of
rising inflation, a common side effect of prolonged and robust growth.

Despite evidence that inflation remained under control, the unexpected
acceleration in economic activity earlier this year caused bond-market
participants to worry that inflation posed a possible threat. This concern
pushed Treasury yields significantly higher. During these six months, Treasury
bond yields fluctuated within a wide range of 98 basis points. In contrast, the
municipal market remained relatively stable, with yields fluctuating within a
much narrower range of 32 basis points.

At the Fund's fiscal year-end in September 1998, the yield spread between
municipal bonds and Treasuries was unprecedentedly narrow. Recently, however, a
slowdown in the supply of new municipal bond issues and rising Treasury yields
caused the yield spread between municipal bonds and Treasury bonds to widen to a
more historically normal range. We believe that this trend will continue and, as
it does, the performance of the municipal market should improve relative to the
Treasury market.

The ongoing economic expansion in the US continued to benefit the municipal bond
market. Municipal bond issuers have been able to improve their financial
situations and, for the fourth year in a row, there were more credit-rating
upgrades than downgrades. We expect that this positive trend will continue.

The Fund's manager, J. & W. Seligman & Co. Incorporated, continues to work to
ensure that all of its operations are prepared for the challenges posed by the
Year 2000 (Y2K) computer issue. We are confident that there will be no
disruption in the investment and shareholder services provided by the Fund as a
result of Y2K. In addition, your portfolio management team considers the
potential ramifications of Y2K when making decisions on which securities should
be held by the Fund.

We appreciate your confidence in Seligman Municipal Fund Series and look forward
to serving your investment needs for many years to come. A discussion with your
Portfolio Manager and the Fund's portfolios of investments follow this letter.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,

THOMAS G. MOLES

Q:  WHAT ECONOMIC AND MARKET FACTORS INFLUENCED SELIGMAN MUNICIPAL FUND SERIES
    IN THE LAST SIX MONTHS?

A:  During the past six months, the outlook for the US and global economies has
    improved dramatically. At fiscal year-end in September 1998, economies
    around the world were struggling with financial crises that threatened to
    drag the US into recession. In response, the Federal Reserve Board took
    immediate defensive action by lowering the federal funds rate three times
    last fall.

    However, the outlook for the US economy brightened as economies around the
    world began to show signs of recovery and as strong US consumer demand
    continued to drive economic growth.

    While ending on a positive note, the last six months were nonetheless
    volatile for equity markets, and thus for the US Treasury market, as
    investors rushed to buy Treasury bonds during periods of market uncertainty.
    This "flight to quality" was the primary cause of the sharp swings in
    Treasury yields that were experienced during the period. The yield on the
    30-year US Treasury bond fluctuated by more than 98 basis points during this
    time.

    In contrast to the volatility of the Treasury market, the municipal market
    remained relatively stable throughout the period. Long-term municipal
    interest rates fluctuated within a much narrower trading range of
    approximately 32 basis points.

    The historically low interest-rate environment led to a surge in municipal
    new issue volume during 1998. The increase in municipal supply caused the
    yield spread between municipal bonds and Treasury bonds to narrow, making
    municipals particularly attractive. For a brief period in October, long-term
    municipal yields actually exceeded long-term Treasury yields, an unusual
    occurrence given the tax advantages of municipal ownership.

    This situation has now begun to reverse itself. Year-to-date, new issue
    volume has slowed from its robust pace, causing the yield spread between
    municipal bonds and Treasury bonds to widen to a historically normal range.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,

THOMAS G. MOLES

    The continued strength of the US economy, which is now in its ninth year of
    economic expansion, has allowed the financial condition of the nation's
    states, cities, and municipalities to steadily improve. For the fourth year
    in a row, credit-rating upgrades exceeded downgrades. We expect that this
    positive trend will continue with the possible exception of health care
    bonds, whose issuers have been experiencing increased financial and
    operating pressures.

Q:  WHAT WAS YOUR INVESTMENT STRATEGY?

A:  The relative lack of volatility in the municipal market limited our
    opportunities to enhance total return through trading activity. Therefore,
    we focused on improving the relative value of Seligman Municipal Fund
    Series' portfolios. Through in-depth credit analysis and market research, we
    have been able to identify municipal credits that we believe have been
    undervalued by the market, and we have used this information in our security
    selection process.

    During the period, our investment strategy was consistent with our positive
    outlook for the economy and long-term interest rates. We reduced portfolio
    holdings with short durations, replacing them with longer-term bonds because
    they offer the greatest opportunity for price appreciation during periods of
    declining interest rates. (Conversely, during periods of rising interest
    rates, long-term bonds will depreciate more than shorter-term bonds.)
    Long-term bonds have also provided the highest yields historically. During
    the past six months, long-term municipal yields rose slightly, resulting in
    declines in Seligman Municipal Fund Series' net asset values.

    We have concentrated new purchases in triple "A" rated insured bonds because
    of the prevailing narrow yield spread between high-quality and lower-quality
    bonds. At this time, lower-quality bonds do not offer enough additional
    yield to compensate for the increased credit risk. For the six-month period,
    high-quality insured bonds outperformed lower-quality bonds.

Q:  WHAT IS YOUR OUTLOOK?

A:  Recent economic reports have suggested that the economy may be strengthening
    further, raising concerns about an acceleration in the rate of inflation. In
    response, long-term municipal yields have increased modestly. However, we
    believe that any increase in long-term yields will be temporary, and our
    outlook for interest rates remains positive. We will continually monitor
    market conditions and will adjust our investment strategy accordingly.

    There are currently a number of factors that bode well for the municipal
    market going forward. First, new issue supply has slowed, widening the yield
    spread between municipals and Treasuries to a historically normal range. If
    this trend continues, and we believe that it will, the performance of the
    municipal market should improve relative to the Treasury market. In
    addition, the municipal bond market has been the beneficiary of a healthy
    economy and a stable rate of inflation, and we anticipate that these
    favorable market conditions will continue for the balance of the year.

   *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 Brothers Municipal Bond Index is an unmanaged index that does not
    include any fees or sales charges. It is composed of approximately 60%
    revenue bonds and 40% state government obligations. Investors cannot invest

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 six months ended March 31, 1999,
   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 six months ended March 31,
1999, 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%. 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. CAPITAL LOSS CARRYFORWARD -- At September 30, 1998, the National and Colorado
Series had net capital loss carryforwards for federal income tax purposes of
$1,559,215 and $115,843, respectively, which are available for offset against
future taxable net capital 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 tables below are intended to help you understand the financial
performance of each Class of each Series for the past five and one-half years or
from its inception if less than five and one-half years. Certain information
reflects financial results for a single share of a Class that was held
throughout the periods shown. Per share amounts are calculated using average
shares outstanding. "Total return" shows the rate that you would have earned (or
lost) on an investment in each Class, assuming you reinvested all your dividend
and capital gain distributions. Total returns do not reflect any sales charges,
and are not annualized for periods of less than one year.

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.

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 or net asset value.

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 -- 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, how shares are bought and sold, fund fees and other
charges, and the fund's financial highlights.

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 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.
