HEATH B.                                HARRY J.
MCLENDON                                ROSENBLUTH

Chairman                                Vice President and
                                        Investment Officer


Dear Shareholder:

We are pleased to present the semi-annual report for the Smith Barney Premium
Total Return Fund ("Fund") for the period ended June 30, 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. In addition, an interview
with Harry J. Rosenbluth, the Fund's Portfolio Manager, appears on page four.


Performance Overview

For the six months ended June 30, 1997, the Fund had a total return of 13.73%
for Class A shares. During this time the U.S. stock market, as measured by the
Standard & Poor's 500 Composite Stock Index ("S&P 500"), had a total return of
20.62%. In addition, the Fund paid monthly dividends that totaled $0.6444 per
Class A share over the same time period. For the year ended June 30, 1997, the
Fund generated a total return of 26.73% for Class A shares.

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 call options that should help to reduce the volatility of the
Fund's net asset value (NAV).


Market Overview and Outlook

Stock prices continued their remarkable surge higher in June as the S&P 500
returned 4.50% for the month. This increase brought the total return for the
broad market index to 17.50% for the second quarter of 1997 -- the strongest
quarterly return for the S&P 500 in over ten years. When combined with its first
quarter result, this benchmark increased 20.62% in the first half of 1997. The
S&P 500 has more than doubled since the end of 1994 and has produced positive
returns in all ten quarters over this period. The last time the market produced
a string of ten or more consecutive quarters with positive returns occurred from
July 1962 through March 1965 when the S&P 500 gained 72%.

Large-capitalization growth stocks continued to push the market higher during
June and throughout the second quarter of 1997. Investors continued to favor the
quality, safety and liquidity of large growth companies such as General
Electric, Procter & Gamble, Gillette and Coca-Cola. The health care, capital
goods and technology sectors each managed returns greater than 20% for the
second quarter of 1997. Every sector of the market posted strong positive
results for both the second quarter and June.

During June, the total return of the Fund trailed that of the broad market S&P
500 index. Relative total Fund performance was hurt during the month by the
Fund's 65% invested position. The Fund began June with an invested position of
65% and ended the month with an effective invested position of about 64%. The
Fund's defensive position hurt its results in June when the stock market rose at
a rapid pace. However, the Fund's equity holdings exceeded the return of the S&P
500. The Fund continues to be overweighted in finance stocks (primarily
mid-sized insurance companies) and underweighted in technology and capital goods
issues.

Investment Strategy

The equity selection process for the Fund remains unchanged. The ideal candidate
for inclusion in the portfolio would possess three broadly defined
characteristics:

     1.   Inexpensive valuation (e.g., low price/earnings ratio ("P/E"), which
          shows the relationship between a stock's price and the company's
          earnings for the last four quarters and low price-to-book ("P/B"),
          which is the price of the stock compared to the difference between the
          company's assets and liabilities)

     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).

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.

We have discussed in a number of past commentaries our concerns that valuation
levels on the stock market as a whole and of many individual stocks were at
record highs. These concerns were in place even before the most recent upward
spike in stock prices. Once again, we believe it's important to put the market's
recent performance in perspective. Historically, the S&P 500 has generated a
total return of roughly 10.7% a year. For the last fifteen years, the total
return of the S&P 500 has averaged more than 18% per year. We believe that 10%
is a realistically sustainable long-term rate of return for stocks.

Companies continue to post record operating profits, and the market is currently
priced for 20% or more returns on equity and 12% to 15% earnings growth in
perpetuity. We do not believe that such returns and growth rates have become
permanent features of our economy. We will continue to tread gingerly in this
very volatile market.

The Fund remains defensively positioned, with about 64% of its assets invested.
Cash reserves were at 13% of assets at the end of the second quarter of 1997,
and S&P 500 Index call options are being used to help lower potential portfolio
volatility. This stance has lowered the effective invested position of the Fund
by an additional 23%. As noted we continue to emphasize financial services and
are underweighted in technology, basic industries and capital goods issues.

The stock market continues to be highly volatile and therefore we remain
cautious. Our investment philosophy and process are geared toward constantly
searching for new investment ideas. Through our proprietary quantitative
screening process and extensive fundamental research we strive to keep the
Fund's portfolio fresh.

We continue to implement our disciplined value style which focuses on buying
companies with low valuations, sound business fundamentals and favorable
business momentum. Accordingly, we continue to find suitable investments for the
Fund's portfolio. At the end of June 1997, the Fund was extremely well
diversified and owned some 161 securities, representing a wide range of
companies and industries.

When faced with stock market uncertainty, we believe that diversification is one
of the keys to controlling risk. We expect market volatility to continue but we
think the Fund is well positioned to deal with this environment.

<PAGE>
 
The Smith Barney Premium Total Return Fund has an options program in place
designed to help reduce portfolio volatility. (An option is the right to buy or
sell a security that is granted in exchange for an agreed upon sum.) We never
engage in random options writing. Investors in the Fund want exposure to
equities but are typically uncomfortable with volatility. We believe our job is
to "make a market call" when conditions warrant. With the stock market trading
at an all-time high and corporations operating at record profitability, we
believe that the probability of the market continuing to advance at recent rates
is low.

On a more somber note, we recently were saddened by the loss of two outstanding
business leaders and Trustees of the Fund, Antoinette C. Bentley and Madelon
DeVoe Talley. Their wisdom and influence will be missed. 

We would like to thank you for your investment in the Smith Barney Premium Total
Return Fund. We look forward to continuing to help you achieve your financial
goals.


Sincerely,

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

An Interview with Portfolio Manager
Harry J. Rosenbluth
================================================================================


We recently had an opportunity for a discussion with Harry J. Rosenbluth,
Portfolio Manager of the Smith Barney Premium Total Return Fund in which he
talked about his value investing philosophy and risk management strategies. Mr.
Rosenbluth, who has been involved in the Premium Total Return Fund for more than
10 years and has more than 16 years of investment experience, assumed management
of the Fund on January 1, 1993.

Harry, what is the Fund's primary investment objective?

Harry: 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 equity 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.

How do you minimize risk in the portfolio?

Harry: Our risk management strategies involve several different aspects.
Historically, dividend-paying stocks have proven less volatile than the overall
equity 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. We adjust the Fund's overall
hedge exposure based on our analysis of current market conditions.

Risk is unavoidable when you invest in stocks. However, one way to minimize risk
is through careful asset allocation. We have the flexibility in the Fund not to
be fully invested. We would be fully invested only if the overall stock market
were inexpensive and there were lots of individual securities that passed our
screening process.

How would you describe your investment philosophy?

Harry: 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.

How do you determine when a stock may be suitable for the Fund?

Harry: The ideal stock possesses three characteristics: it's available at a good
price, the company's long-term fundamentals are sound and its near-term business
is improving. Hands-on research drives our stock-selection process. When we find
a stock with all three characteristics and it also possesses good liquidity, we
will buy a lot of the stock, up to 5 percent of the Fund's portfolio.

A good price for a stock is not defined solely as a low price-earnings ratio or
price-to-book ratio. What's more important to us is the price of the security in
relation to its own history and to its growth potential and profitability
characteristics.

If we believe a security is attractively priced, the second characteristic we
look for is whether the particular company is in the right long-term business.
We ask, "What exactly are the business characteristics that we're buying?" In
addition, we closely examine certain key qualitative factors such as barriers to
entry, distribution systems and operating leverage.

We start by looking at all the public information available on a particular
company. If its fundamental business prospects are good, we contact people who
are in a position to know whether its business momentum is positive, negative or
neutral. For instance, if the company is in the retail business, we would
contact its stores directly to discuss sales. In addition, analyzing the price
of a particular stock also involves other

- --------------------------------------------------------------------------------

quantification methods and examining ratios such as its price-earnings ratios,
price-to-book value and the liquidation value of the company. Moreover, we
employ traditional, fundamental analysis such as reading the 10K and 10Q reports
filed with the SEC. We are trying to find companies that can consistently
generate high returns to capital over a long-term time frame.

Lastly, we look for stocks that are exhibiting positive near-term business
momentum. Quite simply, if we were to pick up the phone and call a CEO or
treasurer and ask them, "Is your business getting better, worse or staying the
same?" we would want them to say that their business is getting better. And not
only improving, but getting better versus its business plan.

With respect to risk control and compounding absolute returns over time, what
you don't 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 keeps us from owning the second type of company.

What is your sell discipline?

Harry: We sell stocks for one of two reasons. First, whenever we purchase a
stock, we set a price target for sale. The price target will be a multiple of
earnings, cash flow, book value et. al. When a stock reaches its price target,
it is sold and the money is deployed elsewhere. Second, we may sell a stock when
their company's near-term business prospects deteriorate. If we see a slowdown
coming in the operating conditions of a company that we hold in the portfolio,
we will sell the stock.

What are some of the market sectors you currently favor?

Harry: Over the past several years we have been overweighted in the financial
services industry. In fact, throughout my career as a portfolio manager I have
always overweighted financial stocks. Most financial company stocks are not well
understood in the marketplace. As a result, in our view many financial stocks
have never really received the valuations they deserve. The financial services
industry should grow at double-digit rates for the foreseeable future. While
there are plenty of poorly managed financial services companies out there
deserving of low valuations, we believe there are several well-run financial
companies poised to take advantage of this growth.

Conversely, we stay generally underweighted in economically sensitive areas of
the economy. Our decision is not based on a belief that the economy may be
slowing down and therefore these companies will perform poorly. Rather,
economically sensitive stocks are today, for the most part, not inexpensive.
Furthermore, these companies generally are in slow-growth, low-return businesses
and have little or no positive near-term business momentum.

Harry, how should investors view the Fund relative to their other mutual fund or
financial holdings?

Harry: We think the Smith Barney Premium Total Return Fund is a fairly
conservative way to participate in the stock market. 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 don't have a strong tolerance for market
volatility. Moreover, 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.

Harry, why did you become a portfolio manager?

Harry: I think it is an intellectually challenging business. To be successful in
this industry, you have to stay current. The world around us is reflected in the
global markets on a daily basis. Moreover, portfolio management is an
entrepreneurial business and the score is kept every day. I enjoy balancing my
competitive will to win with the intellectual challenges of investing.

Smith Barney Premium Total Return Fund
Distribution Policy


A mutual fund pays dividends to satisfy one of the requirements to qualify as a
regulated investment company and to avoid paying income tax at the fund level.
In fact, mutual funds must distribute at least 90% of their investment company
taxable income, but will generally distribute substantially all of its ordinary
net income and net capital gains to avoid federal income and excise taxes.
Accordingly, mutual fund dividends and distributions retain the character of
their source, therefore, the tax benefits of net long-term capital gains can be
passed along to shareholders. In addition, based on its objectives, an
individual fund may, as a result of its distribution policy, return a portion of
the shareholders' principal in the form of a return of capital, which may not be
considered taxable income.

Smith Barney Premium Total Return Fund's ("Fund") distribution policy is
designed to provide an attractive level of monthly distributions. Since 1989,
the Fund has paid out approximately $0.10 per share each month. The Fund's
distribution strategy takes into account the long-term total return potential of
its investment in equities. Over time, the Fund has been able to distribute
income as well as provide its shareholders with moderate growth of principal.
The 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.

     of the maximum initial sales charge of 5.00% and Class B shares reflect the
     deduction of a 5.00% CDSC, which applies if shares are redeemed within one
     year from initial purchase and declines thereafter by 1.00% per year until
     no CDSC occurs. Class C shares reflect the deduction of a 1.00% CDSC, which
     applies if shares are redeemed within the first year of purchase.

+    Hypothetical illustration of $10,000 invested in Class B shares on June 30,
     1987, assuming reinvestment of dividends and capital gains, if any, at net
     asset value through June 30, 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
Tax-Exempt 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 semi-annual reports dated January 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
fund and 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, 1996,
reclassifications are 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 Smith Barney
Mutual Funds Management Inc. ("SBMFM"), which, in turn, is a subsidiary of Smith
Barney Holdings Inc. ("SBH"), 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 0.10% of the average daily net assets of the
Fund. This fee is paid monthly.

SBMFM 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 SBH, acts as distributor of Fund
shares and primary broker for its portfolio agency transactions. For the six
months ended June 30, 1997, SB received brokerage commissions of $722,992 and
sales charges of approximately $902,000 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. For the six months ended June 30, 1997, CDSCs paid to SB were:

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 six
months ended June 30, 1997, total Distribution Plan fees incurred were:

proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:


<TABLE>

Net unrealized appreciation                     $1,023,598,712
================================================================================

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

Notes to Financial Statements (unaudited)(continued)
================================================================================


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.

As of June 30, 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 if the cost of the closing
purchase transaction exceeds the premium received when the option was sold)
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 six months
ended June 30, 1997:

5. Repurchase Agreements

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.

6. Lending of Portfolio Securities

The Fund has an agreement with its custodian whereby the custodian may lend
securities owned by the Fund to brokers, dealers and other financial
organizations. 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 between 2% and 5%
depending on the type of securities loaned. The custodian establishes and
maintains the collateral in a segregated account.

At June 30, 1997, the Fund loaned common stocks having a value of approximately
$623,656,659 and received cash collateral of $647,967,604 for the loan.

7. Shares of Beneficial Interest

At June 30, 1997, the Trust had an unlimited number of shares of beneficial
interest authorized with a par value of $0.001 per share. The Fund has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest and has the same rights, except that each class bears certain
direct expenses specifically related to the distribution of its shares.

At June 30, 1997,  total  paid-in  capital  amounted to the  following  for each
class:

(1)  For the six months ended June 30, 1997 (unaudited).

(2)  Per share amounts have been calculated using the monthly average shares
     method, rather than the undistributed net investment income method, because
     it more accurately reflects the per share data for the period.

(3)  For the period from August 1, 1996 to December 31, 1996.

(4)  For the period from February 7, 1996 (inception date) to July 31, 1996.

(5)  As of September 1995, the SEC instituted new guidelines requiring the
     disclosure of average commissions per share.

     total return for the year.
