Dear Shareholder:

We are pleased to present the annual report for the Smith Barney Premium Total
Return Fund ("Fund") for the year ended December 31, 1997. In this report we
discuss stock market conditions and review our investment strategy during the
reporting period. A more detailed summary of performance and current holdings
can be found in the appropriate sections that follow.

Performance Overview

For the year ended December 31, 1997, the Fund had a total return of 25.19% for
Class A shares without sales charges. During this time the U.S. stock market, as
measured by the Standard & Poor's 500 Composite Stock Index ("S&P 500 Index"),
had a total return of 33.35%. In addition, the Fund paid income dividends that
totalled $0.38 and distributed capital gains of $1.25 per Class A share over the
same time period. Additional performance information regarding the Fund's other
share classes can be found on page five. Morningstar, Inc. assigned the Fund a
four-star* rating for its risk-adjusted performance among 3,821 stock funds as
of December 31, 1997.

The Fund invests primarily in dividend-paying common stocks and employs an
investment strategy that may cause it to underperform in a rising market.
However, the Fund should experience smaller losses when the stock market
declines. One of the key elements of the Fund's investment strategy involves the
use of S&P 500 Index call options that should help to reduce the volatility of
the Fund's net asset value ("NAV").

Market Overview and Outlook

With the S&P 500 Index rising more than 125% over the last three years, our
concerns regarding the valuation level of the stock market and the
sustainability and quality of future corporate earnings growth have never been
greater. We have therefore maintained a defensive posture in the Fund throughout
1997. S&P 500 Index call options were sold to reduce market exposure and to take
advantage of higher stock price volatility. In addition, cash reserve levels in
the Fund averaged about 11% in 1997.

The defensive positioning of the Fund had a negative impact and hurt its
relative performance versus the S&P 500 Index in 1997. As you may know, advances
in the S&P 500 Index were driven primarily by the market's largest companies.

Large-capitalization stocks outperformed small- and mid-capitalization stocks by
a wide margin in 1997. The Russell 2000 Index (an index made up of 2,000
smaller-capitalized U.S.-based companies whose common stocks trade on either the
New York, American or NASDAQ stock exchanges) returned 22.36% for the year. The
average stock mutual fund has a much larger allocation of assets in small- and
mid-capitalization stocks then does a large capitalization stock market index
such as the S&P 500 Index. This holds true for the Smith Barney Premium Total
Return Fund as well. (The average weighted

     performance. Ratings are subject to change monthly and are calculated from
     the Fund's three-, five- and ten-year average annual returns in excess of
     90-day Treasury bill returns with appropriate fee and sales charge
     adjustments, and a risk factor that reflects Fund performance below 90-day
     T-bill returns. Different classes within a fund share a common portfolio of
     securities. In an investment category, the top 10% of funds receive five
     stars and the next 22.5% receive four stars. The Fund received a four-star
     rating for the three- and five- year periods among 262 and 159 funds,
     respectively. Star ratings for individual classes may vary. Past
     performance is no guarantee of future results.

market capitalization of the Fund as of December 31, 1997 was roughly $19.7
billion versus the S&P 500 average weighted market capitalization of more than
$50 billion. Market capitalization is the value of a company's outstanding
shares of common stock calculated by multiplying the number of shares
outstanding by the share price.) While our selection of stocks in the Fund
remained strong in 1997, the invested position of the portfolio, coupled with
its lower market capitalization, are the main reasons why the Fund had a
performance shortfall relative to the S&P 500 during 1997.

Portfolio activity in the Fund was robust during the period under review. We
continue to follow a disciplined value investment approach that focuses on
buying companies with low valuations, sound business fundamentals and favorable
business momentum. This approach continues to generate new investment ideas.

There were only four changes made in the Fund's ten-largest holdings during the
reporting period. We began the year with an international flavor in the
portfolio's largest holdings, as three of the Fund's top-ten largest positions
were foreign stocks held in American Depository Receipt ("ADR") form. (An
American Depository Receipt is a certificate that trades on a U.S. stock market
but represents a non-U.S. stock.) These stocks were Alcatel Alshom, Inc.
(France's second largest company engaged in varied businesses including
telecommunications, energy, nuclear power and transportation, which remained a
0.9% portfolio position as of December 31, 1997); Telefonica de Espana S.A.
(Spanish national telecommunications and cable television service provider. This
remained a 0.5% holding as of December 31, 1997); and Repsol, S.A.

At the end of the year, the Fund's top-ten list counted Ace Ltd. (a
Bermuda-based reinsurance company) as its only foreign holding. In addition, the
Fund was extremely well diversified and owned some 150 securities, representing
a wide range of companies and industries. During the reporting period, we
emphasized tobacco, insurance, pharmaceutical and retail stocks. The Fund was
underweighted in technology, basic industries and capital goods stocks in 1997.

Investment Strategy

The Fund's main investment objective is to provide investors with long-term
total return by investing primarily in dividend-paying stocks. Our goal is to
give people exposure to the stock market -- a market that has historically
produced the highest returns relative to other investment classes -- with less
risk to principal than if they had invested in the stock market on their own. We
believe the best way to accumulate and build wealth is to compound absolute
returns.

We are "bottom up" investors who take a total return approach to investing. We
look for undervalued stocks and select them one at a time because of each
stock's characteristics. In our view the best way to find these undervalued
stocks is through a bottom-up approach combining qualitative and quantitative
techniques. Our starting point is always individual stocks, never "big picture"
economic forecasting.

The stock selection process for the Smith Barney Premium Total Return Fund
remained unchanged during the reporting period. The ideal candidate for
inclusion in the portfolio would possess three broadly defined characteristics:

     1.   Inexpensive valuation (e.g., low price/earnings ratio, price-to-book
          ratio, price to net asset value)

     2.   Sound long-term business fundamentals (e.g., high operating returns
          relative to invested capital, balance sheet strength, a strong
          competitive position)

     3.   Positive near-term business momentum (e.g., improving business trends)

First of all, the Fund's portfolio exhibits excellent value characteristics --
the price paid for a stock is always the primary consideration. In addition, the
portfolio's companies display strong business fundamentals and have better than
average business momentum.

<PAGE>
 
Our risk management strategies involve several different aspects. Historically,
dividend-paying stocks have proven less volatile than the overall stock market.
Beyond that, careful stock selection should help to further reduce risk. We
periodically use options, primarily S&P 500 Index calls, as part of our hedging
strategy to minimize volatility. (An option is the right to buy or sell a
security that is granted in exchange for an agreed upon sum.) We adjust the
Fund's overall hedge exposure based on our analysis of current market
conditions.

The Fund's option program is designed to help reduce portfolio volatility. We
never engage in random options writing. Investors in the Fund want exposure to
stocks but are typically uncomfortable with volatility. We believe our job is to
manage a fully diversified portfolio that seeks to control risk and maximize
investment returns over the long run.

With respect to risk control and compounding absolute returns over time, we
believe that what you do not own is often more important than what you do own.
If we do our job correctly, we avoid owning two kinds of stocks: 1) those of
very good companies that are overpriced; and 2) statistically inexpensive stocks
that either have very poor long-term business prospects or poor near-term
business momentum. Given our value orientation, it's usually easy for us to
avoid owning the first kind of company. Our extensive fundamental research and
investment discipline normally keep us from owning the second type of company.

We view the Fund as ideal for investors who realize they need to be in stocks
because of their long-term capital appreciation potential but do not have a
strong tolerance for market volatility. Moreover, as noted, because we
periodically use options in an attempt to reduce the Fund's volatility over
time, the Fund tends to be less risky than the average stock fund.

In light of greater stock market volatility and higher investor uncertainty of
late, we believe that diversification is one of the keys to control risk. We
think the Smith Barney Premium Total Return Fund is well positioned for the
market conditions we expect in the coming year.

Thank you for your investment in the Smith Barney Premium Total Return Fund. We
look forward to continuing to help you pursue your financial goals.

Sincerely,

/s/ Heath B. McLendon                  /s/ Harry J. Rosenbluth

Smith Barney Premium Total
Return Fund Distributions

Smith Barney Premium Total Return Fund's distribution practice has been to
provide an attractive level of monthly distributions. As in the past, during
1997 the Fund paid out approximately $0.10 per share each month. This practice
takes into account the long-term total return potential of the Fund's investment
in equities. Over time the Fund has been able to distribute income as well as
provide its shareholders with moderate growth of principal. Smith Barney Premium
Total Return Fund meets its distribution objective by paying out to shareholders
substantially all dividends, interest and net capital gains earned over the
course of the year. In certain years, the Fund's distributions may also
supplement this income with a return of capital to maintain the fixed payout.
Each year, shareholders of the Fund receive a 1099 federal tax form indicating
the amount of the distributions that represented ordinary income (dividends,
interest and short-term capital gains), long-term capital gains and return of
capital. The Fund's Board of Trustees monitors and evaluates the distribution
practice to ensure that its continuation remains in the best interest of
shareholders.

+    Hypothetical illustration of $10,000 invested in Class B shares on December
     31, 1987, assuming reinvestment of dividends and capital gains, if any, at
     net asset value through December 31, 1997, compared to the Standard &
     Poor's 500 Index. The index is composed of 500 widely held common stocks
     listed on the New York Stock Exchange, American Stock Exchange and
     over-the-counter market. The index is unmanaged and is not subject to the
     same management and trading expenses as a mutual fund. The performance of
     the Fund's other classes may be greater or less than the Class B shares'
     performance indicated on this chart, depending on whether greater or lesser
     sales charges and fees were incurred by shareholders investing in the other
     classes.
     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

1.   Significant Accounting Policies

The Smith Barney Premium Total Return Fund ("Fund"), a separate investment fund
of Smith Barney Income Funds ("Trust"), a Massachusetts business trust, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Trust consists of this
Fund and six other separate investment funds: Smith Barney Exchange Reserve
Fund, Smith Barney Convertible Fund, Smith Barney High Income Fund, Smith Barney
Municipal High Income Fund, Smith Barney Diversified Strategic Income Fund and
Smith Barney Utilities Fund. The financial statements and financial highlights
for the other Funds are presented in separate annual reports dated July 31,
1997.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) investments are
valued at market value or, in the absence of market value with respect to any
portfolio securities, at fair value as determined by or under the direction of
the Board of Trustees. Portfolio securities that are traded primarily on a
domestic or foreign exchange are valued at the last sale price on that exchange
or, if there were no sales during the day, at the current quoted bid price.
Over-the-counter securities are valued on the basis of the bid price at the
close of business each day. Options are generally valued at the last sale price
or, in the absence of the last price, the last offer price. Investments in U.S.
government securities (other than short-term securities) are valued at the mean
of the quoted bid and asked price; (c) securities maturing within 60 days are
valued at cost plus accreted discount, or minus amortized premium, which
approximates value; (d) interest income, adjusted for amortization of premium
and accretion of discount, is recorded on the accrual basis; (e) dividend income
is recorded on the ex-dividend date; foreign dividend income is recorded on the
ex-dividend date or as soon as practical after the Fund determines the existence
of a dividend declaration after exercising reasonable due diligence; (f)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (g) gains or losses on the sale of securities calculated by using the
specific identification method; (h) the accounting records are maintained in
U.S. dollars. All assets and liabilities denominated in foreign currencies are
translated into U.S. dollars based on the rate of exchange of such currencies
against U.S. dollars on the date of valuation. Purchases and sales of
securities, and income and expenses are translated at the rate of exchange
quoted on the respective date that such transactions are recorded. Differences
between income and expense amounts recorded and collected or paid are adjusted
when reported by the custodian bank; (i) direct expenses are charged to each
class; management fees and general fund expenses are allocated on the basis of
relative net assets of each class; (j) the character of income and gains
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. At December 31, 1997,
reclassifications were made to the Portfolio's capital accounts to reflect
permanent book/tax differences and income and gains available for distributions
under income tax regulations. Net investment income, net realized gains and net
assets were not affected by this change; (k) the Fund intends to comply with the
applicable provisions of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve it from substantially all Federal income
and excise taxes; and (l) estimates and assumptions are required to be made
regarding assets, liabilities and changes in net assets resulting from
operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

In addition, the Fund may from time to time enter into options and/or futures
contracts in order to hedge market risk.

2.   Investment Advisory Agreement, 
     Administration Agreement and 
     Other Transactions

Smith Barney Strategy Advisers Inc. ("SBSA"), a subsidiary of Mutual Management
Corp. ("MMC"), formerly known as Smith Barney Mutual Funds Management Inc.
which, in turn, is a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment adviser to the Trust. The Fund pays SBSA an advisory fee
calculated at an annual rate of 0.55% of the average daily net assets. This fee
is calculated daily and paid monthly.

SBSA has entered into a sub-advisory agreement with Boston Partners Asset
Management, L.P. ("Boston Partners"). Pursuant to the sub-advisory agreement,
Boston Partners is responsible for the day-to-day portfolio operations and
investment decisions for the Fund. SBSA pays Boston Partners a monthly fee
calculated at an annual rate of 0.15% of the average daily net assets of the
Fund. This fee is paid monthly.

MMC also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets. This fee
is calculated daily and paid monthly.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares and primary broker for its portfolio agency transactions. For the
year ended December 31, 1997, SB received brokerage commissions of $936,326 and
sales charges of approximately $1,746,000 for sales of the Fund's Class A
shares.

There is a contingent deferred sales charge ("CDSC") of 5.00% on Class B shares,
which applies if redemption occurs within one year from initial purchase and
declines thereafter by 1.00% per year until no CDSC is incurred. Class C shares
have a 1.00% CDSC, which applies if redemption occurs within the first year of
purchase. In addition, Class A shares have a 1.00% CDSC, which applies if
redemption occurs in the first year of purchase. This CDSC applies only to those
purchases of Class A shares which, when combined with current holdings of Class
A shares, equal or exceed $500,000 in the aggregate. These purchases do not
incur an initial sales charge. For the year ended December 31, 1997, CDSCs paid
to SB were:

================================================================================
</TABLE>

Pursuant to a Distribution Plan, the Fund pays a service fee with respect to
Class A, B and C shares calculated at the annual rate of 0.25% of the average
daily net assets of each respective class. The Fund also pays a distribution fee
with respect to Class B and C shares calculated at the annual rate of 0.50% and
0.45% of the average daily net assets of each class, respectively. For the year
ended December 31, 1997, total Distribution Plan fees incurred were:

4.   Option Contracts

Premiums paid when put or call options are purchased by the Fund, represent
investments, which are marked-

to-market daily. When a purchased option expires, the Fund will realize a loss
in the amount of the premium paid. When the Fund enters into a closing sales
transaction, the Fund will realize a gain or loss depending on whether the
proceeds from the closing sales transaction are greater or less than the premium
paid for the option. When the Fund exercises a put option, it will realize a
gain or loss from the sale of the underlying security and the proceeds from such
sale will be decreased by the premium originally paid. When the Fund exercises a
call option, the cost of the security which the Fund purchases upon exercise
will be increased by the premium originally paid.

At December 31, 1997, the Fund had no open purchased call or put options.

When a Fund writes a call or put option, an amount equal to the premium received
by the Fund is recorded as a liability, the value of which is marked-to-market
daily. When a written option expires, the Fund realizes a gain equal to the
amount of the premium received. When the Fund enters into a closing purchase
transaction, the Fund realizes a gain or loss depending upon whether the cost of
the closing transaction is greater or less than the premium originally received,
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is eliminated. When a written call option
is exercised the cost of the security sold will be decreased by the premium
originally received. When a written put option is exercised, the amount of the
premium originally received will reduce the cost of the security which the Fund
purchased upon exercise. When written index options are exercised, settlement is
made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Fund enters into options for hedging purposes. The risk in writing a
covered call option is that the Fund gives up the opportunity to participate in
any increase in the price of the underlying security beyond the exercise price.
The risk in writing a put option is that the Fund is exposed to the risk of loss
if the market price of the underlying security declines.

The following written call option transactions occurred during the year ended
December 31, 1997:

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires continual maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

securities owned by the Fund to brokers, dealers and other financial
organizations, and receives a lenders fee. Fees earned by the Fund on securities
lending are recorded in interest income. Loans of securities by the Fund are
collateralized by cash, U.S. Government securities or high quality money market
instruments that are maintained at all times in an amount at least equal to the
current market value of the loaned securities, plus a margin which may vary
depending on the type of securities loaned. The custodian establishes and
maintains the collateral in a segregated account. The Fund maintains exposure
for the risk of any losses in the investment of amounts received as collateral.

At December 31, 1997, the Fund had loaned common stocks having a value of
approximately $477,385,466 and holds the following collateral for loaned
securities:

Independent Auditors' Report
================================================================================

The Shareholders and Board of Trustees of
Smith Barney Income Funds:

     We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of Smith Barney Premium Total Return Fund
of Smith Barney Income Funds as of December 31, 1997, and the related statement
of operations for the year then ended, the statements of changes in net assets
for the year ended December 31, 1997 and for the period from August 1, 1996 to
December 31, 1996, and the financial highlights for the year ended December 31,
1997, the period from August 1, 1996 to December 31, 1996 and for each of the
years in the two-year period ended July 31, 1996. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for each of
the years in the two-year period ended July 31, 1994, were audited by other
auditors whose report thereon, dated September 19, 1994, expressed an
unqualified opinion on those financial highlights.

     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. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodian. As to securities
purchased or sold but not yet received or delivered, we performed other
appropriate auditing procedures. 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
Smith Barney Premium Total Return Fund of Smith Barney Income Funds as of
December 31, 1997, and the results of its operations for the year then ended,
the changes in its net assets for the year ended December 31, 1997 and for the
period from August 1, 1996 to December 31, 1996 and the financial highlights for
the year ended December 31, 1997, the period from August 1, 1996 to December 31,
1996 and each of the years in the two-year period ended July 31, 1996, in
conformity with generally accepted accounting principles.
