The graph depicts the performance of PaineWebber National Tax-Free Income Fund
versus the Bond Buyer 20-Bond General Obligation Index and the Lehman Brothers
Municipal Bond Index. It is important to note PaineWebber National
Tax-Free Income Fund is a professionally managed mutual fund while the indexes
are not available for investment and are unmanaged. The comparison is shown for
illustrative purposes only.

The Fund's performance benchmark has been changed to the Lehman Brothers
Municipal Bond Index. The Lehman Index is a more widely followed benchmark of
municipal bond returns and is believed to be a more appropriate broad-based
index for comparison with the total return performance of the Fund. The Fund's
prior benchmark, the Bond Buyer Index, is also shown in this report's
performance graph but will not appear in subsequent reports.

TAX-FREE BOND FUNDS                                                ANNUAL REPORT



                                                                  April 14, 1998


Dear Shareholder,

We are pleased to present you with the annual report for PaineWebber National
Tax-Free Income Fund, PaineWebber Municipal High Income Fund, PaineWebber New
York Tax-Free Income Fund and PaineWebber California Tax-Free Income Fund for
the fiscal year ended February 28, 1998.


GENERAL MARKET OVERVIEW
================================================================================

[GRAPHIC APPEARS HERE]
The credit markets rallied strongly from beginning to end of the Funds' fiscal
year. The long Treasury bond finished up, yielding below 6.00% from a 6.60%
starting point. Most of the move came in the early part of the fiscal year;
during the last three months the long bond stayed in a 25-basis-point (0.25%)
range.

  The central factors driving this move were: a steadily improving economy
without inflation, Asian economic unrest potentially causing a slowdown in the
United States, demand for U.S. financial assets by investors fleeing Asia and
the perception that the Federal Reserve would not increase short-term interest
rates.

  Municipal bonds also gained through the fiscal year, although they trailed the
U.S. Treasury market. Municipal issuers took advantage of historically low rates
to refinance outstanding debt with new, lower yielding bonds. At February 28,
1998, municipal yields were 86% of comparable-maturity Treasury yields, which
bodes well for municipal bonds. On average, municipals yield 82-83% of
comparable Treasuries. This yield relationship tends to return to its average,
meaning municipal prices could gain or Treasury prices could fall, or some
combination of both.


Portfolio Review
================================================================================
PAINEWEBBER NATIONAL TAX-FREE INCOME FUND

[GRAPHIC APPEARS HERE]
PERFORMANCE

The Fund's total return (the net asset value change with dividends reinvested)
for the fiscal year ended February 28, 1998, without deducting sales charges,
was 9.48% for Class A shares, 8.62% for Class B shares, 8.92% for Class C shares
and 9.87% for Class Y shares. The Fund's Class A shares outperformed the Lipper
median manager in the General Municipal Funds peer group by 38 basis points
(0.38%).

  For shareowners who purchased or redeemed Fund shares during the period, the
Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 5.11% for
Class A shares, 3.62% for Class B shares, 8.17% for Class C shares and 9.87% for
Class Y shares.

Portfolio Highlights

Our disciplined investment style -- focused on duration, sector allocation and
security selection -- allowed us to outperform our peers during this period.
Purchasing bonds with 50-basis-point (0.50%) premiums helped the Fund's
performance, as these bonds started pricing to their call dates versus their
maturity dates (thus rolling down the maturity curve). Diversifying across the
credit spectrum -- mainly into more BBB's, BB's and nonrated issues -- helped
too, as these issues performed better than higher-rated credits for the period.

Our hospital bond positions underperformed generally. However, since we are
underweighted in hospitals compared to our Lipper peer group, hospital issues
did not affect our performance as much as theirs.

Our Holdenville Oklahoma holding best represents the success of our investment
strategy. After extensive research, in late 1996 we purchased a Baa-rated jail-
lease bond that yielded 1.30% above an equivalent-maturity AAA bond. Less than
one year later, the issuer sold a new issue and used the proceeds to escrow our
position. This "prerefunding" allowed us to sell our bonds at a gain.

We are still positive on the power sector (19.9% of net assets as of February
28, 1998); we expect further consolidation to lead to lower issuance and more
prerefundings as municipalities respond to customers' ability to choose power
vendors. We hope to increase our single-family housing allocation (2.5% of net
assets as of February 28, 1998) if we can fine-tune individual issue prepayment
rates.

We are generally positive on interest rates, believing that inflation will stay
down within the context of a moderately healthy economy. In accordance with this
view, we are maintaining the Fund's duration slightly above that of its Lipper
peer group.



PAINEWEBBER MUNICIPAL HIGH INCOME FUND


PERFORMANCE

The Fund's total return (the net asset value change with dividends reinvested)
for the fiscal year ended February 28, 1998, without deducting sales charges,
was 11.06% for Class A shares, 10.23% for Class B shares and 10.51% for Class C
shares. Class Y shares were not outstanding for the entire fiscal year ended
February 28, 1998. The total return for Class Y shares from commencement on
February 5, 1998 is -0.09%, with and without deduction of sales charges. The
Fund's Class A shares outperformed the Lipper Municipal High Yield peer group by
81 basis points (0.81%).

For shareowners who purchased or redeemed Fund shares during the period the
Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 6.65% for
Class A shares, 5.23% for Class B shares and 9.76% for Class C shares. Class Y
shares were not outstanding for the entire fiscal year ended February 28, 1998.

for Class Y shares from commencement on February 5, 1998 is -0.09%, with the
deduction of sales charges.

Portfolio Highlights

During the last six months the Fund benefited from the refunding of several of
its holdings. In late 1996 we purchased Baa-rated Holdenville, Oklahoma jail-
lease bonds that yielded 1.30% above an equivalent-maturity AAA bond. Less than
one year later, the issuer sold a new issue and used the proceeds to escrow our
position. This "prerefunding" allowed us to sell our bonds at a gain. Also, our
investment in bonds for a convention center in Myrtle Beach, South Carolina was
refunded in January 1998.

Several investment themes currently give focus to our industry and security
selections. The stable, moderate-growth economy, with its low inflation and high
consumer confidence, continue to bode well for the leisure and travel
industries. One of the issues we like is Black Hawk, Colorado Water Bonds, to
supply water to casinos (1.5% of net assets on February 28, 1998). The economic
recovery of Southern California presents attractive investment opportunities as
municipalities there undertake new infrastructure projects, such as our
investment in aquarium bonds for Long Beach, California (3.1% of net assets on
February 28, 1998). This investment also connects with our travel and leisure
theme.

We favor select companies in the power industry; those that we think will
benefit from consolidation as consumers get to choose their suppliers. At this
time, we are not keen on hospital bonds and have kept them to only 5% of the
Fund's net assets for some time. (Most of our Lipper competitors hold hospital
positions of about 15%.) Hospital issues underperformed during the last six
months, turning our underweighting into a relative advantage.

In the last report we asserted that narrowing credit spreads were justified, but
that we weren't sure how much longer the narrowing would continue. In fact, it
continued through the end of the Fund's fiscal year (February 28, 1998) and on
into March. Because spreads have narrowed so much already, we feel it's time to
take a more cautious stance with the Fund's portfolio. Therefore, we have begun
to increase the Fund's overall quality as a defensive move. Recently we
purchased the Fund's first A-rated credit in several years, bonds issued by
Pilchuck, Washington (1.6% of net assets as of February 28, 1998).

In an environment of such tight credit spreads there is little room for error;
we will therefore emphasize security selection and quality enhancement. While we
may give up some yield, we think that shareholders will be best served by taking
a cautious approach in the months ahead.

PAINEWEBBER NEW YORK TAX-FREE INCOME FUND

Performance

  The Fund's total return (the net asset value change with dividends reinvested)
for the fiscal year ended February 28, 1998, without deducting sales charges,
was 9.36% for Class A shares, 8.65% for Class B shares and 8.82% for Class C
shares.

  For shareowners who purchased or redeemed Fund shares during the period the
Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 5.02% for
Class A shares, 3.65% for Class B shares and 8.07% for Class C shares.

Portfolio Highlights

  During the fiscal year, the main contributors to the Fund's performance were
rebalancing across the credit curve as spreads compressed and picking ideally
structured securities at peak spots along the maturity curve. Issues such as
Local Government Assistance Corporation, NYS Thruway Authority and NYS
Environmental Authority (3.7%, 4.8% and 3.7%, respectively, of net assets on
February 28, 1998) not only benefited our shareholders for the above mentioned
reasons but were also prerefunded to their first call dates, causing large
price increases.

  We have been and still are positive on the utility sector. We foresee supply
dwindling as issuers delve into the world of consumer choice. Some issuers are
even issuing taxable paper to open up a greater customer base. NY Power
Authority (2.3% of net assets on February 28, 1998) is prerefunding all
outstanding debt to get out of restrictive bond covenants.

  Expanding our research efforts resulted in our timely purchase of a Brooklyn
Navy Yard (Baa3) issue. This position (2.3% of net assets on February 28, 1998)
has turned in a strong performance since we bought it in December 1997.

were not outstanding for the entire fiscal year ended February 28, 1998. From
their commencement on February 5, Class Y shares returned -0.34%, with and

PORTFOLIO HIGHLIGHTS

  During the year ended February 28, 1998, and particularly in the most recent
six months, improvements in the relative rate of interest rates brought an
onslaught of refinancing deals. Issuers took advantage of lower market rates to
prerefund higher-cost bond debt. Prerefunding accelerated the performance of
those bonds and contributed largely to strong performance for the period. Among
our attractive holdings (as percent of net assets on February 28, 1998) was
Santa Clara Valley Medical Center (1.5%).

  In this rally new issuance coupons of long bonds drifted to 4.50% and
resistance to the absolute levels of interest materialized. Some investors split
away from discount bonds and moved into higher premium bonds. Thus, moderate-
premium bonds grew to more substantial premiums in this rally and performed
well. Many of our core holdings consist of premium bonds in the 20-year range
with coupons between 5.5% and 6.0%.

  The third significant event that marked this period was the narrowing of
traditional spreads. Yield compression was seen across the credit spectrum and
across sectors, although it was most evident in the credit spectrum. Lower-rated
securites, having seen the most narrowing, proved to be strong performers.

  The Fund participated well in this rally: our exposure to premium bonds
contributed to our performance. We were under-weighted in lower-rated credits,
however, and therefore did not benefit greatly from their performance. We will
seek to increase our holdings of Baa and lower issues, but we will not
compromise our quality standards to do so. We remain diligent in our search for
relative value and proper compensation for additional investment risk.

OUTLOOK
================================================================================

  We think 1998 will be a strong year for the U.S. bond markets. The U.S.
economy is slowing slightly due to Asia, though the effects will not show up in
economic statistics for a while. We expect inflation to run at a 1.5% annual
rate. The Federal budget is now running a surplus, which should reduce
government borrowing and ease the upward pressure on market interest rates. We
think rates could fall one- to three-tenths of a percent if present conditions
persist.

                                                                               9

NOTES TO FINANCIAL STATEMENTS
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 man-
agement 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 (no
Class Y shares were outstanding during the period for New York Tax-Free Income
Fund). 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 re-
invested shares automatically convert to Class A shares approximately six years
after initial issuance. All classes of shares have equal voting privileges, ex-
cept that each class has exclusive voting rights with respect to its service
and/or distribution plan.
 The preparation of financial statements in accordance with generally accepted
accounting principles requires Fund management to make estimates and assump-
tions that affect the reported amounts and disclosures in the financial state-
ments. 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
 
38
<PAGE>
 
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 Fund uses 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 differ-
ences 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 solely in municipal obligations of their
respective states. 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 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, 1998, 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, 1998, California Tax-Free Income Fund, National Tax-Free
Income Fund, Municipal High Income Fund and New York Tax-Free Income Fund owed
Mitchell Hutchins $125,749, $120,182,
 
                                                                              39
<PAGE>
 
NOTES TO FINANCIAL STATEMENTS
$45,650 and $16,907, respectively, in investment advisory and administration
fees. During the year ended February 28, 1998 Mitchell Hutchins voluntarily
waived $101,675 in investment advisory and administration fees from the New
York Tax-Free Income Fund.
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, 1998, California Tax-
Free Income Fund, National Tax-Free Income Fund, Municipal High Income Fund and
New York Tax-Free Income Fund owed Mitchell Hutchins $97,270, $97,956, $37,559
and $17,849, respectively, in service and distribution fees. For the year ended
February 28, 1998, Mitchell Hutchins voluntarily waived $13,884 in service and
distribution fees from New York Tax-Free Income Fund.
 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, 1998, it earned $145,737, $201,738, $210,046 and $74,056 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
 Prior to August 1, 1997, each Fund paid PaineWebber an annual fee of $4.00 per
active PaineWebber shareholder account, plus certain out-of-pocket expenses,
for certain services not provided by the Fund's transfer agent. For these serv-
ices for the period ended July 31, 1997, PaineWebber earned $5,924, $15,757,
$5,104 and $2,077 from California Tax-Free Income Fund, National Tax-Free In-
come Fund, Municipal High Income Fund and New York Tax-Free Income Fund, re-
spectively. For the period ended July 31, 1997, PaineWebber voluntarily waived
$1,791 in transfer agency service fees from New York Tax-Free Income Fund.
 Subsequent to July 31, 1997, PaineWebber provides transfer agency related
services to each Fund pursuant to a delegation of authority from PFPC Inc., the
Funds' transfer agent, and is compensated for these services by PFPC Inc., not
the Funds. For the seven months ended February 28, 1998, PaineWebber received
from PFPC Inc., not the Funds, approximately 47%, 47%, 47% and 39% of the total
transfer agency and related service fees collected by PFPC Inc. from the Cali-
fornia Tax-Free Income Fund, National Tax-Free Income Fund, Municipal High In-
come 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,
1998, was substantially the same as the cost of securities for financial state-
ment purposes.
 At February 28, 1998, 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 appli-
cable 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, 1998, the Funds had the following net capital loss
carryforwards available as reductions, to the extent provided in the regula-
tions, of future net realized capital gains which expire as follows:

 The capital loss carryforwards of National Tax-Free Income Fund of $1,074,491
relate to its acquisition on November 3, 1995, of Mitchell Hutchins/Kidder,
Peabody Municipal Bond Fund, and may be limited to its use by the Internal
Revenue Code.
 To the extent that any such losses are used to offset future capital gains, it
is probable that the gains so offset will not be distributed.

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, 1998, 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 at February 28, 1998 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, 1998, 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
** ALL LONG-TERM CAPITAL GAINS DISTRIBUTIONS ARE TAXED AT A 20% RATE.
 
 The California Tax-Free Income Fund did not invest in any security which paid
interest subject to the federal alternative minimum tax for individual
taxpayers during its fiscal year. Therefore, none of the dividends paid by this
fund were subject to such tax. Additionally, 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 1998. 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 1999. Shareholders are advised to consult their own tax
advisers with respect to the tax consequences of their investment in each Fund.
