TAX-FREE BOND FUNDS                                                ANNUAL REPORT

Dear Shareholder,

We are pleased to present you with the annual 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
fiscal year ended February 28, 1999.

GENERAL MARKET OVERVIEW

The mid-August crisis in Russia and fears of its spread to Latin America
heightened investors' aversion to credit risk and prompted them to sell other
securities in favor of U.S. Treasurys. The "flight to quality" ultimately drove
U.S. Treasury bond yields to a low of 4.70% in October. To fend off a
threatening global financial crisis, the Federal Reserve cut the short-term
interest rate by 0.25% three times in as many months, lowering them from 5.50%
to 4.75%. Investors returned in search of bargains as the bond markets began to
stabilize.

   Once the turmoil settled down, rates remained in the low 5% range until early
February 1999, when Federal Reserve Chairman Alan Greenspan delivered his annual
Humphrey-Hawkins testimony to Congress. In his testimony, Chairman Greenspan
expressed an inclination to restrain economic policy and confessed that he might
have overdone interest-rate cuts during the fall crisis. This surprised market
participants, and the yield on the 30-year Treasury bond rose by about one-half
percent to reflect fears of rising rates. Actual economic statistics for the
period, however, belied investors' concerns.

   As Treasury yields rose in February, municipal bonds strongly outperformed
taxable bonds, reversing their underperformance of 1998. In August 1998,
municipal bonds had yielded about 94% of taxable bonds. By fiscal year-end,
municipal bond yields had improved to around 84% of taxable bonds, the result of
significant municipal bond outperformance. The interest-rate backup contributed
to municipal bond outperformance -- as rates rose municipalities delayed their
financing, which further decreased supply.

                                                                               5

PORTFOLIO REVIEWS

PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND

PERFORMANCE

The Fund's total return consists of the change in net asset value with dividends
reinvested. For the fiscal year ended February 28, 1999, without deducting sales
charges, Class A shares gained 5.90%, Class B shares gained 5.06%, Class C
shares gained 5.35% and Class Y shares gained 6.28%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares gained 1.71%, Class B shares gained 0.15% and
Class C shares gained 4.61%. Class Y shares are not subject to sales charges.

PORTFOLIO HIGHLIGHTS

   We continued to pursue our goal of diversifying the Fund's portfolio during
the six months ended February 28, 1999. Most significantly, we added a
zero-coupon-bond component to the portfolio, purchasing bonds issued by
Escondido (1.7%*) and San Jose Santa Clara School Districts (1.0%). We
perennially seek to capture value in "structure spreads," that is, yield
differences between bond issues with different payback structures. For example,
we purchased the callable San Jose Santa Clara zero-coupon bonds at a price that
translated to a yield 39 basis points (0.39%) higher than that issuer's
current-income bond, an attractive spread for this structure.

   Within the Fund's non-callable sector, we added small positions in Natomas
School District (0.7%) and Inglewood Redevelopment Agency (0.7%). New
acquisitions in the nonrated sector included Lake Elsinore Recreation Authority
(1.2%) and a small increase in the Fund's holdings of Virgin Island Water and
Power (1.3%). Nonrated holdings comprised 9.5% of the portfolio at period-end.
During this period of municipal outperformance versus taxable bonds we enhanced
total return by extending portfolio duration one-third of a year. (Duration is a
measure of a Fund's exposure to interest-rate risk.)

OUTLOOK

California's issuance of new bonds has been moderate to slightly heavy, and has
kept pace with previous issuance rates. However, demand for California
securities has grown and their yields relative to non-California municipals are
near historical lows -- "rich" in industry parlance. We do not expect the
richness of California debt to diminish unless the supply balance changes
dramatically.

PAINEWEBBER NATIONAL TAX-FREE INCOME FUND

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended February 28, 1999, without
deducting sales charges, Class A shares gained 5.31%, Class B shares gained
4.48%, Class C shares gained 4.76% and Class Y shares gained 5.49%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares gained 1.09%, Class B shares lost 0.42% and Class
C shares gained 4.02%. Class Y shares are not subject to sales charges.

PORTFOLIO HIGHLIGHTS

   The cheapest part of the yield curve, the 15-20 year range, remained the
focus of our purchases. Generally, we added 30-60 basis-point premium bonds to
the Fund. (A basis point equals 1/100th of one percent.) We believe these
securities offer the greatest return potential for their effective duration
(interest-rate risk exposure), giving shareholders a higher yield without
increasing market risk. A typical addition was the block of small-premium bonds
issued by San Antonio Texas (1.0%*) due in 2015, which yielded 5.25% and were
rated Aa2/AA+. This strategy increased the Fund's yield and thus helped
performance.

   In pursuit of this strategy of enhancing yield, we also increased the Fund's
allocation to such lower credit quality sectors as BBB-rated and nonrated bonds.
We are taking more credit risk among shorter maturity securities, where market
risk generally is lower. Among our notable purchases were nonrated Virgin Island
Water and Sewer bonds due in 2012 (0.3%). These bonds carry a Mitchell Hutchins
internal rating of BBB-. These lower credit quality purchases improved the
Fund's yield, which translated into better performance.

PAINEWEBBER MUNICIPAL HIGH INCOME FUND

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended February 28, 1999, without
deducting sales charges, Class A shares gained 4.80%, Class B shares gained
3.87%, Class C shares gained 4.25% and Class Y shares gained 4.96%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares gained 0.58%, Class B shares lost 1.09% and Class
C shares gained 3.51%. Class Y shares are not subject to sales charges.

PORTFOLIO HIGHLIGHTS

   The Fund suffered last August when municipal yield spreads to Treasurys
widened, especially among the Fund's lower-quality credits. Also, the Fund's
relatively short duration hurt it when the Federal Reserve cut interest rates.
(Longer-duration portfolios gain more than shorter-duration portfolios when
interest rates fall.) After the market stabilized, the Fund's performance
improved and returned to its prior trend of general outperformance.

   We have avoided the hospital sector for a long time, believing that an
oversupply of hospitals would lead to financial troubles for many of them. The
Fund benefited from its underweighting -- during the period the entire hospital
sector suffered from the default of several issuers. The Fund also benefited by
avoiding waste management bonds. The sector has suffered from downgrades
following unfavorable court rulings against issuers and a spate of takeovers.

   During the fiscal year the Fund bought Alexandria, Virginia bonds for
Buckingham Village Apartments (3.5%*), a lower-income housing project. Housing
projects can be risky investments -- low occupancy rates and high operating
costs can result in significant losses. Such bonds require thorough top-down and
bottom-up analysis. Our top-down analysis was positive: Alexandria is part of
the Washington D.C. metropolitan area, which faces a shortage of moderately
priced housing. From a bottom-up perspective, Buckingham Village is a well-kept
postwar apartment building that only needed minor upgrading. These factors
reassure us that occupancy rates in Buckingham Village are likely to remain
high, and we believe the project should keep making its debt payments.

   Private placements offer above-market yields to compensate for being harder
to sell and for their credit risk. The Fund bought private placements issued to
fund construction of public facilities such as health

department laboratories, child protection centers and corrections department
offices. We believe demand for such facilities is unlikely to fade over time. A
typical purchase was the Fund's participation in a placement by Harris County,
Texas (1.9%*). We consider these securities the equivalent of a high "A" credit
rating, yet the Fund gets a return well in excess of the market rate for A-rated
bonds.

OUTLOOK

   With the market turbulence apparently behind us, we think our long-term
investment themes remain valid and applicable over the next few years. We still
like the airline and travel industries, which continue to benefit from the solid
economy. Also, we remain bullish on the power and utilities sector, where we
think that uncertainty over deregulation has created buying opportunities. Our
bottom-up analysis has identified projects and companies that we believe will
perform well regardless of the form deregulation takes.

   The large spreads of municipals to taxable securities have narrowed as
municipal prices have risen, and spreads are likely to remain stable for a
while. In this more stable climate we'll look to enhance yield where we can by
selling some of our winners and, we hope, picking new ones. We continue to look
for opportunities to enhance total return through the accrual of tax-exempt
income and bond price appreciation, but we will not lower our credit quality
standards for the sake of either.

/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
or less than their original cost. Capital gain distributions and gains realized
on the sale of Fund shares are taxable.

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 distribu-
tion plan.
 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 of Investments--Where market quotations are readily available, port-
folio securities are valued thereon, provided such quotations adequately re-
flect the fair value of the securities, in the judgment of Mitchell Hutchins
Asset Management Inc. ("Mitchell Hutchins"), a wholly owned asset management
subsidiary of PaineWebber Incorporated ("PaineWebber") and investment adviser,
administrator and distributor of the Funds. When market quotations are not
readily available, securities are valued based upon appraisals received from a
pricing service which utilizes a computerized matrix system, or based upon ap-
praisals derived from information concerning those securities or similar secu-
rities received from recognized dealers in those securities. All other securi-
ties are valued at fair value as determined in good faith by or under the di-
rection of each Trust's board of trustees. The amortized cost method of valua-
tion, which approximates market value, is used to value debt obligations with
60 days or less remaining to maturity, unless the respective Trust's board of
trustees determines that this does not represent fair value.
 Investment Transactions and Investment Income--Investment transactions are re-
corded on the trade date. Realized gains and losses from investment transac-
tions are calculated on the identified cost method. Interest income is recorded
on an accrual basis. Discounts are accreted and premiums are amortized as ad-
justments to interest income and the identified cost of securities.
 Income and expenses (excluding class-specific expenses) are allocated propor-
tionately to each class of shares based upon the relative value of dividend el-
igible 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
 
                                                                              39

Notes to Financial Statements
current capital share activity of the respective class). Class-specific ex-
penses 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 securi-
ties 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 mar-
gin 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 in-
come 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 ob-
ligations 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 obli-
gations 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 tempo-
rary financing until the settlement of sale or purchase of portfolio securi-
ties, the repurchase or redemption of shares of the Funds at the request of the
shareholders and other temporary or emergency purposes. In connection there-
with, each Fund has agreed to pay a commitment fee, pro rata, based on the rel-
ative 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 year ended February 28, 1999, the Funds did not borrow under the Facil-
ity.
Investment Adviser and Administrator
 Each Trust's board of trustees has approved an Investment Advisory and Admin-
istration 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 as-
sets. At February 28, 1999, California Tax-Free Income Fund, National Tax-Free
Income Fund, Municipal High Income Fund and New York Tax-Free Income Fund owed
Mitchell Hutchins $35,062, $114,877,
 
40
<PAGE>
 
Notes to Financial Statements
$50,610 and $3,766, respectively, in investment advisory and administration
fees. For the year ended February 28, 1999 Mitchell Hutchins voluntarily waived
$200,824 and $112,366 in investment advisory and administration fees from the
California Tax-Free Income Fund and New York Tax-Free Income Fund, respective-
ly.
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 February 28, 1999, California Tax-
Free Income Fund, National Tax-Free Income Fund, Municipal High Income Fund and
New York Tax-Free Income Fund owed Mitchell Hutchins $44,258, $89,568, $40,946
and $16,822, 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 year
ended February 28, 1999, it earned $164,517, $209,660, $112,785 and $53,051 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, respective-
ly.
Transfer Agency Service Fees
 PaineWebber provides transfer agency related services to each Fund pursuant to
a delegation of authority from PFPC Inc., each Funds' transfer agent, and is
compensated for these services by PFPC Inc., not the Funds. For the year ended
February 28, 1999, PaineWebber received from PFPC Inc., not the Funds, approxi-
mately 52%, 50%, 53% and 55% of the total transfer agency and related service
fees collected by PFPC Inc. from the California Tax-Free Income Fund, National
Tax-Free Income Fund, Municipal High Income Fund and New York Tax-Free Income
Fund, respectively.
Investments in Securities
 For federal income tax purposes, the cost of securities owned at February 28,
1999, was substantially the same as the cost of securities for financial state-
ment purposes.
 At February 28, 1999, the components of net unrealized appreciation of invest-
ments were as follows:

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 28,1999, National Tax-Free Income Fund had $394,177 of capital
loss carryforwards available relating to its acquisition on November 3, 1995 of
Mitchell Hutchins/Kidder, Peabody Municipal Bond Fund, which will expire by
February 28, 2003. 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.

(1) Total investment return is calculated assuming a $1,000 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 sales charges or program fees; results would be lower if sales
    charges or program fees were included. Total investment return for periods
    of less than one year has not been annualized.

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each year 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 year reported. The figures do not
    include sales charges; results would be lower if sales charges were
    included.
(2) These ratios include non-recurring acquisition expenses of 0.03%.

Report of Ernst & Young LLP,
Independent Auditors
 
The Board of Trustees and Shareholders
PaineWebber Mutual Fund Trust
PaineWebber Municipal Series
 
 We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments, of PaineWebber Mutual Fund Trust
(comprising PaineWebber California Tax-Free Income Fund and PaineWebber
National Tax-Free Income Fund), and PaineWebber Municipal Series (comprising
PaineWebber Municipal High Income Fund and PaineWebber New York Tax-Free Income
Fund) (the "Trusts") as of February 28, 1999, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights
for each of the periods indicated therein. These financial statements and
financial highlights are the responsibility of the Trusts' 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 and financial highlights. Our procedures included confirmation of
investments owned as of February 28, 1999 by correspondence with the custodian
and brokers. 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective funds constituting PaineWebber Mutual Fund Trust and
PaineWebber Municipal Series at February 28, 1999, the results of their
operations for the year then ended, the changes in their net assets for each of
the two years in the period then ended, and the financial highlights for each
of the indicated periods, in conformity with generally accepted accounting
principles.

* Federally exempt interest dividends
** Taxable as ordinary income
*** All long-term capital gains distributions are taxed at a 20% rate.
 
 All exempt interest dividends paid by California Tax-Free Income Fund and New
York Tax-Free Income Fund were exempt from California state income tax and New
York state and city income tax, respectively.
 
 Because each Fund's fiscal year is not the calendar year, another notification
will be sent in respect of calendar year 1999. The second notification, which
reflects the amount to be used by calendar year taxpayers on their federal
income tax returns, will be made in conjunction with Form 1099 DIV and will be
mailed in January 2000. Shareholders are advised to consult their own tax
advisers with respect to the tax consequences of their investment in each Fund.
