RMA MONEY MARKET FUNDS                                   SEMIANNUAL REPORT


                                                        February 19, 1999

Dear Shareholder,

   We are pleased to present you with the semiannual report for the 
PaineWebber RMA Money Market Portfolio; the PaineWebber RMA U.S. Government 
Portfolio; the PaineWebber RMA Tax-Free Fund, Inc.; the PaineWebber RMA 
California Municipal Money Fund; the PaineWebber RMA New York Municipal Money 
Fund; and the PaineWebber RMA New Jersey Municipal Money Fund for the 
six-month period ended December 31, 1998.

MARKET REVIEW
- ------------------------------------------------------------------------------

       Money market mutual fund assets increased during the period as 
[ICON] investors emphasized safety of principal in response to volatility 
in the financial markets.  The Federal Reserve cut the Federal Funds rate by 
0.25% in September, October and November, lowering it from 5.50% to 4.75%. At 
the same time, European central banks were cutting rates in preparation for 
the January 1, 1999 debut of the euro currency.

   Lower interest rates helped to calm the global financial markets, which 
had become unsettled after Russia's default in August. Money-market yields 
were lower across the short-term yield curve.  Because inflation remained 
low, however, money-market yields stayed relatively strong on an 
inflation-adjusted basis and versus overseas short-term rates.

OUTLOOK

         The Federal Reserve is likely to maintain a steady monetary policy 
[ICON]   given strong U.S. economic growth and weak global growth.  We expect 
the U.S. economy to grow more slowly in 1999, with inflation remaining low 
and no recession on the immediate horizon.

PORTFOLIO REVIEWS
- ------------------------------------------------------------------------------

   We remained slightly bullish on the fixed income markets over the six 
months ended December 31, 1998, expecting interest rates to hold steady or 
fall slightly. Since we did not expect major changes in rates, we kept the 
Portfolios' weighted average maturities slightly long, about 5-10 days above 
the averages of their peer groups.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  PaineWebber RMA Money Fund, Inc. (the "Corporation") and PaineWebber RMA
Tax-Free Fund, Inc. ("RMA Tax-Free") were organized under the laws of Maryland
on July 2, 1982 and are registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended, as open-end management
investment companies. RMA Tax-Free is a diversified mutual fund and the
Corporation is a series mutual fund with three portfolios, each of which are
diversified series: PaineWebber RMA Money Market Portfolio ("Money Market
Portfolio"), PaineWebber RMA U.S. Government Portfolio ("U.S. Government
Portfolio") and PaineWebber Retirement Money Fund. The financial statements of
PaineWebber Retirement Money Fund are not included herein.
 
  PaineWebber Managed Municipal Trust ("Managed Municipal Trust") and
PaineWebber Municipal Money Market Series ("Municipal Money Market Series") were
organized under Massachusetts law by Declarations of Trust dated November 21,
1986 and September 14, 1990, respectively, and are registered with the
Securities and Exchange Commission under the Investment Company Act of 1940, as
amended, as open-end management investment companies. Managed Municipal Trust
currently offers two non-diversified series of shares: PaineWebber RMA
California Municipal Money Fund ("RMA California") and PaineWebber RMA New York
Municipal Money Fund ("RMA New York"). Municipal Money Market Series currently
offers one non-diversified series of shares: PaineWebber RMA New Jersey
Municipal Money Fund ("RMA New Jersey", and when referred together with Money
Market Portfolio, U.S. Government Portfolio, RMA Tax-Free, RMA California and
RMA New York collectively, the "Funds").
 
  The preparation of financial statements in accordance with generally accepted
accounting principles requires Fund management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies:
 
  VALUATION AND ACCOUNTING FOR INVESTMENTS AND INVESTMENT INCOME--Investments
are valued at amortized cost which approximates market value. Investment
transactions are recorded on the trade date. Realized gains and losses from
investment transactions are calculated using the identified cost method.
Interest income is recorded on the accrual basis. Premiums are amortized and
discounts are accreted as adjustments to interest income and the identified cost
of investments.
 
  REPURCHASE AGREEMENTS--The Funds' custodian takes possession of the collateral
pledged for investments in repurchase agreements. The underlying collateral is
valued daily on a mark-to-market basis to ensure that the value, including
accrued interest, is at least equal to the repurchase price. In the event of
default of the obligation to repurchase, each Fund has the right to liquidate
the collateral and apply the proceeds in satisfaction of the obligation. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/ or retention of the collateral may subject to
legal proceedings.
 
  DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions is
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.

CONCENTRATION OF RISK
 
  The ability of the issuers of the debt securities held by the Funds to meet
their obligations may be affected by economic developments, including those
particular to a specific industry or region.
 
  Additionally, RMA California, RMA New York and RMA New Jersey follow an
investment policy of investing primarily in municipal obligations of one state.
Economic changes affecting each state and certain of their public bodies and
municipalities may affect the ability of issuers within each state to pay
interest on, or repay principal of, municipal obligations held by each of those
Funds.
 
INVESTMENT ADVISER AND ADMINISTRATOR
 
  Each Fund has entered into a board approved Investment Advisory and
Administration Contract ("Advisory Contract") with PaineWebber Incorporated
("PaineWebber"), under which PaineWebber serves as investment adviser and
administrator. In accordance with the Advisory Contract, each Fund pays
PaineWebber an investment advisory and administration fee, which is accrued
daily and paid monthly, in accordance with the following schedule:
