PAINEWEBBER TAX-FREE BOND FUNDS                               SEMIANNUAL REPORT

Dear Shareholder,                                             October 16, 2000

We are pleased to present you with the semiannual report for PaineWebber
California Tax-Free Income Fund, PaineWebber National Tax-Free Income Fund,
PaineWebber Municipal High Income Fund and PaineWebber New York Tax-Free Income
Fund for the six-month period ended August 31, 2000.

MARKET REVIEW

[ICON] During the six-month period ended August 31, 2000, market sentiment
toward the fixed-income markets changed dramatically for the better. A
broad-based decline in stock prices triggered renewed interest in the relative
stability of fixed-income investments. In addition, investors reacted favorably
to evidence that the Federal Reserve Board's tight monetary policy of raising
short-term interest rates was having the desired effect of containing inflation
and slowing the pace of economic growth. In general, an environment of
relatively low inflation and moderate economic growth is positive for bonds.

   In the tax-exempt area of the market, many state and local municipalities
enjoyed continued prosperity. Several years of robust economic growth and low
unemployment have boosted property tax valuations and tax revenues. As a result,
the coffers of many municipalities are relatively full.

   Both municipal and high-yield municipal bonds rallied during the period;
however, the performance of high-yield bonds lagged that of higher-rated
securities. Nevertheless, the performance of the municipal market, as measured
by the Lehman Brothers Municipal Bond Index, rose 6.79% for the six months ended
August 31, 2000. For the same period, municipal bonds outperformed the taxable
bond market. The Lehman Brothers Aggregate Bond Index, which tracks the
performance of taxable bonds, gained 5.53%.

OUTLOOK

   Because the bond market has advanced significantly during the past six
months, it is possible that it will take a breather in the short term before
continuing its positive trend. Recent economic data indicate that the Federal
Reserve Board may have achieved its goal of a "soft landing," one in which the
economy slows but does not move into recession. If so, there may be no further
interest-rate hikes. An environment of moderate economic growth and relatively
stable interest rates should be positive for fixed-income investments.


                                                                               1

PORTFOLIO HIGHLIGHTS

   For the six-month period ended August 31, 2000, all share classes
outperformed both the Lipper California Municipal Debt Median and the Lipper
Municipal Bond Index. An average duration (a measure of a bond portfolio's
sensitivity to interest rate changes) that was shorter than the benchmark helped
contribute to the positive performance, and overweighting in the 15-to-20 year
area of the yield curve continued to aid performance.

   Lower bond supply and increased demand have continued to benefit the
short-maturity end of the municipal curve. The curve has begun to steepen on the
long end, however, as long bonds have responded positively to the probability
that interest rates will remain stable at least through year-end. Bullish
sentiment marked May and especially June, when reinvested cash and the
expiration of June municipal bond futures helped to bolster the market. Demand
for California issues has been strong, with 10-year bonds performing 25 to 30
basis points higher than their AAA counterparts, which represent the strongest
national general

obligation bonds. (A basis point equals 1/100 of one percent.)

   In June, we added two new bonds to our portfolio. One, issued by San
Francisco International Airport (2.4%),* was deeply discounted and added nine
basis points in yield. This purchase makes the airport sector one of the top
five in the Fund. The other bond, Little Lake City School District (0.9%),* was
purchased as a premium coupon bond, providing an opportunity to buy a larger
coupon with a minimal price premium.

   Going forward, the Fund is poised to take advantage of opportunities
presented in the market. Both weighted average duration and weighted average
maturity have shortened since the beginning of the period. As has been the case
for most of this year, we expect the 15-20 year area of the municipal yield
curve to remain the most attractive.

PROPOSED FUND MERGER

   On October 6, 2000, the board of trustees unanimously approved the merger of
the PaineWebber California Tax-Free Income Fund into the MFS California
Municipal Bond Fund. The proposed merger will be submitted to shareholders at
meetings expected to be held in February 2001. If approved by the PaineWebber
fund's shareholders, the merger is expected to become effective in March 2001.

   More information about the proposed merger for the PaineWebber California
Tax-Free Income Fund is set out in the October 10, 2000 supplement to the
prospectus dated June 30, 2000 and additional information will be provided to
shareholders in proxy solicitation materials that are expected to be mailed in
December 2000.

PORTFOLIO HIGHLIGHTS

   On the heels of the huge Treasury debt buyback in February, the period began
positively as the Fund returned 2.2% in March. April, however, was a different
story as the economy continued to overheat, prompting speculation of yet another
interest rate increase by the Federal Reserve. Both Treasurys and the municipal
market stalled while awaiting the latest interest rate hike in mid-May. Since
then, the economy has stabilized, interest rates are predicted to remain stable
through the end of the year and bond markets, in general, have rebounded.

   For the six-month period ended August 31, 2000, the Fund's various share
classes were in line with or slightly lower than the Lehman Brothers Municipal
Bond Index and the Lipper General Municipal Debt Funds Median, with Class A
shares returning 6.49%.

   Strong market momentum marked most of the summer, as mostly comforting
economic news combined with a scarcity of new issues, particularly in the
10-year range. This lower bond supply has limited the opportunities to acquire
premium coupon bonds, but we have found relative value in the 15-25 year range
of the municipal yield curve.

   California 10-year bonds in particular continue to perform strongly,
outperforming the AAA ten-year by 25-30 basis points. (A basis point equals
1/100th of one percent.) Other states also have shown such relative value
compared to the AAA ten-year. More than half of our portfolio consists of debt
from Texas, Illinois, New York, California and Indiana.

   We will continue to monitor credit quality in the secondary markets which
featured some poorly structured bonds, as well as the yield curve, which has
increased on the long maturity end in recent months. The curve tends to flatten
during interest rate increases and steepens at the end of most interest rate
tightening cycles. The announced intention by the Treasury in August to buy back
$750 million in shorter-term debt also marks the first time in almost a year
that 30-year bonds remain relatively untouched by the buyback, which may temper
enthusiasm on the long end of the Treasury yield curve.

PROPOSED MERGER AND NEW FUND MANAGEMENT
================================================================================

On October 6, 2000, the board of trustees unanimously approved
the merger of the PaineWebber National Tax-Free Income Fund into the PACE
Municipal Fixed Income Investments. The proposed merger will be submitted to
shareholders at meetings expected to be held in January 2001. If approved by the
PaineWebber fund's shareholders, the merger is expected to become effective no
later than early March 2001.

   On October 6, 2000, the board of trustees for the PaineWebber fund terminated
the existing Investment Advisory and Administration Contract with Mitchell
Hutchins relating to that PaineWebber fund and approved new interim investment
management arrangements that became effective on October 10, 2000, including a
new interim sub-advisory contract with Standish, Ayer & Wood, Inc. who took over
day-to-day portfolio management of the fund effective October 10, 2000.

PORTFOLIO HIGHLIGHTS

   While bonds across the board rallied during the six-month period ended August
31, 2000, the performance of high-yield bonds trailed that of higher-rated
securities.

   High-yield securities were affected by countervailing forces. On one hand,
they benefited from declining long-term interest rates and higher bond prices.
On the other hand, their performance was held back, because as investors
returned to the fixed-income markets, they tended to favor higher-quality
issues. The possibility of slower economic growth also dampened the
attractiveness of high-yield securities. Investors became concerned that a
decline in economic growth would adversely affect companies that issue
high-yield securities more than it would affect companies that issue
investment-grade securities.

   During the period, the Federal Reserve Board continued to raise short-term
interest rates, but even as short-term rates rose, long-term interest rates
declined. Because interest rates and bond prices move in opposite directions,
the drop in

long-term rates aided the Fund. As long-term rates fell, the prices generally
rose on the existing long-term bonds in the portfolio.

   In managing the portfolio, we maintained our discipline of seeking value
in various fixed-income sectors. We tended to favor investments in the power,
leisure, paper, airlines and lease-financing areas of the market. We avoided
sectors such as healthcare and resource recovery, where economic fundamentals
were unattractive. While we moved cautiously when investing available cash,
we believe we made some attractive purchases.

   In March, we purchased Pittsylvania County, VA Industrial Development
Authority bonds. These bonds are secured by a wood-burning electric plant that
operates as one of the more efficient plants in the area. The bonds have a 7.5%
coupon and a relatively short 2014 maturity.

   In May, we added Houston Community College District bonds to the portfolio.
We purchased the obligations of this successful district at the lowest prices
prevailing in the bond market at the time.

   The monitoring of markets to sell securities that we believe have become
fully valued is a fundamental part of our investment strategy. As a result, the
Fund benefited from the sale of two significant holdings. In May, we sold Loudon
County, Virginia, 71/8% Economic Development Bonds due 2015 when we saw a very
strong bid that we believed represented a price well above the bond's credit
rating.

   In August, we sold San Diego County, California bonds secured by Burnham
Research Institute. We purchased this issue in 1999 when many California
offerings temporarily depressed the market. The economics of medical research
have improved considerably since we added these bonds to the portfolio. As a
result, the San Diego County bonds became more highly regarded by investors and
the bonds became fully priced. We used the proceeds from the sale of San Diego
County bonds to purchase Northcumberland County, Pennsylvania bonds.

   The Fund's performance was held back by a position in Tooele County Utah
Hazardous Waste Disposal Bonds, which are secured by Laidlaw, a provider of
ambulances, school buses and inter-city buses. In March, Tooele County Bonds
declined significantly, when the company faced a financial crisis. We continue
to hold Tooele Country bonds in the portfolio, and we believe they should
recover significantly over the next year or two.

PAINEWEBBER TAX-FREE BOND FUNDS                             SEMIANNUAL REPORT

PORTFOLIO HIGHLIGHTS

   During the period ended August 31, 2000, the Fund's average annual return for
Class A shares stood at 6.77%, in line with the Lehman Brothers Municipal Bond
Index at 6.79% and the Lipper New York Municipal Debt Funds Median at 6.61%.
Class B and C shares came in slightly under the averages for the Index and
median, while Class Y shares slightly outperformed the averages. A weighted
average duration (a measure of a bond portfolio's sensitivity to interest rate
changes) that was shorter than the benchmark helped contribute to the positive
performance, and overweighting in the 15-to-20 year area of the municipal curve
continued to aid performance.

   The latest six-month period was nothing if not eventful. After a strong
March, buoyed by the early-year Treasury buy-back, April and May performance
stuttered, resulting in negative months, as concerns about an overheating
economy and additional interest rate increases persisted. Following an interest
rate hike in mid-May, the market and the Fund rebounded throughout the summer. A
smaller-than-average number of new issues contributed to increased demand, while
a lack of damaging economic news and the hope that interest rates would remain
stable through year-end helped to boost the market.

   Some credit concerns remain in secondary markets because of poorly structured
bonds, but we continue to place an emphasis on credit quality, with almost 90%
of the Fund's holdings rated A or above. The weighted average maturity and
weighted average duration continue slightly below benchmark, giving us the
flexibility to seek out opportunities when they develop.

   Our top five state holdings remain the same from the start of the period,
although the general obligation sector--our largest sector--comprises slightly
less of the Fund's assets than it did six months ago. In contrast, we have
increased our stake in the university sector, which now comprises 11.7% of the
Fund's assets. New York City obligations make up 20.6% of state
holdings.

(1)  Figures assume reinvestment of all dividends and other distributions at net
     asset value on the payable dates and do not include sales charges; results
     for each class would be lower if sales charges were included. Total
     investment return for periods of less than one year has not been
     annualized.

The data above represents past performance of the Fund's shares, which is no
guarantee of future results. The principal value of an investment in the Fund
will fluctuate, so that an investor's shares, when redeemed, may be worth more

(1)  Figures assume reinvestment of all dividends and other distributions at net
     asset value on the payable dates and do not include sales charges; results

guarantee of future results. The principal value of an investment in the Fund
will fluctuate, so that an investor's shares, when redeemed, may be worth more
or less than their original cost. Capital gain distributions and gains realized
on the sale of Fund shares are taxable.

guarantee of future results. The principal value of an investment in the Fund
will fluctuate, so that an investor's shares, when redeemed, may be worth more
or less than their original cost. Capital gain distributions and gains realized

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)



ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     PaineWebber Mutual Fund Trust ("Mutual Fund Trust") and PaineWebber
Municipal Series ("Municipal Series") (collectively, the "Trusts") were
organized under Massachusetts law by Declarations of Trust dated November 21,
1986 and January 28, 1987, respectively, and are registered with the Securities
and Exchange Commission under the Investment Company Act of 1940, as amended, as
an open-end diversified management investment company and an open-end
non-diversified management investment company, respectively. Mutual Fund Trust
has two series: PaineWebber California Tax-Free Income Fund ("California
Tax-Free Income Fund") and PaineWebber National Tax-Free Income Fund ("National
Tax-Free Income Fund"). Municipal Series has two series: PaineWebber Municipal
High Income Fund ("Municipal High Income Fund") and PaineWebber New York
Tax-Free Income Fund ("New York Tax-Free Income Fund") (collectively, the
"Funds").

     Currently, each Fund offers Class A, Class B, Class C and Class Y shares.
Each class represents interests in the same assets of the applicable Fund and
the classes are identical except for differences in their sales charge
structures, ongoing service and distribution charges and certain transfer agency
expenses. In addition, Class B shares and all corresponding dividend reinvested
shares automatically convert to Class A shares approximately six years after
initial issuance. All classes of shares have equal voting privileges, except
that each class has exclusive voting rights with respect to its service and/or
distribution plan.

     The preparation of financial statements in accordance with accounting
principles generally accepted in the United States 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 OF INVESTMENTS--Each Fund calculates its net asset value based on
the current market value for its portfolio securities. The Funds normally obtain
market values for their securities from independent pricing sources. Independent
pricing sources may use reported last sale prices, current market quotations or
valuations from computerized "matrix" systems that derive values based on
comparable securities. Securities traded in the over-the-counter ("OTC") market
and listed on The Nasdaq Stock Market, Inc. ("Nasdaq") normally are valued at
the last sale price on Nasdaq prior to valuation. Other OTC securities are
valued at the last bid price available prior to valuation. Securities which are
listed on U.S. and foreign stock exchanges normally are valued at the last sale
price on the day the securities are valued or, lacking any sales on such day, at
the last available bid price. In cases where securities are traded on more than
one exchange, the securities are valued on the exchange designated as the
primary market by Mitchell Hutchins Asset Management Inc. ("Mitchell Hutchins"),
the investment adviser and administrator of the Funds. Mitchell Hutchins is a
wholly owned subsidiary of PaineWebber Incorporated ("PaineWebber"), a wholly
owned subsidiary of Paine Webber Group Inc. ("PW Group"). If a market value is
not available from an independent pricing source for a particular security, that
security is valued at fair value as determined in good faith by or under the
direction of the Funds' board of trustees (the "board"). The amortized cost
method of valuation, which approximates market value, generally is used to value
short-term debt instruments with sixty days or less remaining to maturity,
unless the board determines that this does not represent fair value.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)



     INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are
recorded on the trade date. Realized gains and losses from investment
transactions are calculated on the identified cost method. Interest income is
recorded on an accrual basis. Discounts are accreted and premiums are amortized
as adjustments to interest income and the identified cost of securities.

     Income and expenses (excluding class-specific expenses) are allocated
proportionately to each class of shares based upon the relative value of
dividend eligible shares of each class at the beginning of the day (after
adjusting for current capital share activity of the respective classes).
Realized and unrealized gains and losses are allocated proportionately to each
class of shares based upon the relative value of shares outstanding at the
beginning of the day (after adjusting for current capital share activity of the
respective class). Class-specific expenses are charged directly to the
applicable class of shares.

     FUTURES CONTRACTS--Upon entering into a financial futures contract, the
Funds are required to pledge to a broker an amount of cash and/or municipal
securities equal to a certain percentage of the contract amount. This amount is
known as the "initial margin." Subsequently, payments, known as "variation
margin," are made or received by the Funds each day, depending on the daily
fluctuations in the value of the underlying financial futures contracts. Such
variation margin is recorded for financial statement purposes on a daily basis
as unrealized gain or loss until the financial futures contract is closed, at
which time the net gain or loss is reclassified to realized.

     Using financial futures contracts involves various market risks. The
maximum amount at risk from the purchase of a futures contract is the contract
value. The Funds use financial futures contracts in strategies intended to
enhance income or for hedging purposes. However, imperfect correlations between
futures contracts and the portfolio securities being hedged, or market
disruptions, do not normally permit full control of these risks at all times.

     DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders
are recorded on the ex-dividend date. The amount of dividends and distributions
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.

CONCENTRATION OF RISK

     Each Fund follows an investment policy of investing primarily in municipal
obligations of various states except for California Tax-Free Income Fund and New
York Tax-Free Income Fund which invest primarily in municipal obligations of
their respective states. This concentration of investments may subject these
Funds to greater risks. Economic changes affecting those states and certain of
their public bodies and municipalities may affect the ability of the issuers
within those states to pay interest on, or repay principal of, municipal
obligations held by those Funds.

BANK LINE OF CREDIT

     Each Fund may participate with other funds managed by Mitchell Hutchins in
a $200 million committed credit facility ("Facility") to be utilized for
temporary financing until the settlement of sale or purchase of portfolio
securities, the repurchase or redemption of shares of the Funds at the request
of the shareholders and other temporary or emergency purposes. In connection
therewith, each Fund has agreed to pay a commitment fee, pro rata, based on the
relative asset size of the Funds in the Facility. Interest is charged to each
Fund at rates based on prevailing market rates in effect at the time of
borrowings. For the six months ended August 31, 2000, the Funds did not borrow
under the Facility.

                                                                              43

INVESTMENT ADVISER AND ADMINISTRATOR

     Each Trust's board has approved an Investment Advisory and Administration
Contract ("Advisory Contract") with Mitchell Hutchins, under which Mitchell
Hutchins serves as investment adviser and administrator of the Funds. In
accordance with the Advisory Contracts, each Fund pays Mitchell Hutchins an
investment advisory and administration fee, which is accrued daily and paid
monthly, at the annual rates of 0.50% of California Tax-Free Income Fund's and
National Tax-Free Income Fund's average daily net assets and 0.60% of Municipal
High Income Fund's and New York Tax-Free Income Fund's average daily net assets.
At August 31, 2000, California Tax-Free Income Fund, National Tax-Free Income
Fund, Municipal High Income Fund and New York Tax-Free Income Fund owed Mitchell
Hutchins $32,134, $105,391, $46,645 and $10,203, respectively, in investment
advisory and administration fees. For the six months ended August 31, 2000,
Mitchell Hutchins voluntarily waived $126,492 and $52,035 in investment advisory
and administration fees from the California Tax-Free Income Fund and New York
Tax-Free Income Fund, respectively.

     On July 12, 2000, PW Group and UBS AG ("UBS") announced that they had
entered into an agreement and plan of merger under which PW Group will merge
into a wholly owned subsidiary of UBS. If all required approvals are obtained
and the required conditions are satisfied, PW Group and UBS expect to complete
the transaction in the fourth quarter of 2000. UBS, with headquarters in
Zurich, Switzerland, is an internationally diversified organization with
operations in many areas of the financial services industry.

DISTRIBUTION PLANS

     Mitchell Hutchins is the distributor of each Fund's shares and has
appointed PaineWebber as exclusive dealer for the sale of those shares. Under
separate plans of distribution pertaining to Class A, Class B and Class C
shares, each Fund pays Mitchell Hutchins monthly service fees at the annual rate
of 0.25% of the average daily net assets of each class of shares and monthly
distribution fees at the annual rate of 0.75% and 0.50% of the average daily net
assets of Class B and Class C shares, respectively. At August 31, 2000,
California Tax-Free Income Fund, National Tax-Free Income Fund, Municipal High
Income Fund and New York Tax-Free Income Fund owed Mitchell Hutchins $40,132,
$78,753, $34,886 and $13,527, respectively, in service and distribution fees.

     Mitchell Hutchins also receives the proceeds of the initial sales charges
paid by shareholders upon the purchase of Class A shares and the contingent
deferred sales charges paid by shareholders upon certain redemptions of Class A,
Class B and Class C shares. Mitchell Hutchins has informed each Fund that, for
the six months ended August 31, 2000, it earned $61,533, $50,784, $60,657 and
$28,169 in sales charges for the California Tax-Free Income Fund, National
Tax-Free Income Fund, Municipal High Income Fund and New York Tax-Free Income
Fund, respectively.

TRANSFER AGENCY SERVICE FEES

     PaineWebber provides transfer agency related services to each Fund pursuant

FEDERAL TAX STATUS

     Each Fund intends to distribute all of its tax-exempt income and any
taxable income and to comply with the requirements of the Internal Revenue Code
applicable to regulated investment companies. Accordingly, no provisions for
federal income taxes are required. In addition, by distributing during each
calendar year substantially all of its net investment income, capital gains and
certain other amounts, if any, each Fund intends not to be subject to a federal
excise tax.

     At February 29, 2000, California Tax-Free Income Fund had $87,023 of
capital loss carryforwards available, which will expire by February 28, 2008. To
the extent that any net capital loss carryforwards are used, as provided in the
regulations, to offset future capital gains, it is probable that the gains so
offset will not be distributed. In accordance with U.S. Treasury regulations,
California Tax-Free Income Fund, National Tax-Free Income Fund, Municipal High
Income Fund and New York Tax-Free Income Fund have elected to defer $1,051,063,
$904,221, $774,879 and $56,267, respectively, of realized capital losses arising
after October 31, 1999. Such losses are treated for tax purposes as arising on
March 1, 2000.

*   Annualized.
(1) Total investment return is calculated assuming a $10,000 investment on
    the first day of each period reported, reinvestment of all dividends and
    distributions at net asset value on the payable dates and a sale at net
    asset value on the last day of each period reported. The figures do not
    include any applicable sales charges; results would be lower if they were
    included. Total investment return for a period of less than one year has
    not been annualized.

*   Annualized.
(1) Total investment return is calculated assuming a $10,000 investment on
    the first day of each period reported, reinvestment of all dividends and
    distributions at net asset value on the payable dates and a sale at net
    asset value on the last day of each period reported. The figures do not
    include any applicable program fees; results would be lower if they were
    included. Total investment return for a period of less than one year has
    not been annualized.

*    Annualized.
(1)  Total investment return is calculated assuming a $10,000 investment on the
     first day of each period reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each period reported. The figures do not
     include any applicable program fees; results would be lower if they were
     included. Total investment return for periods of less than one year has
     not been annualized.
