Dear Shareholder:
 
  Strong individual issue selection, careful monitoring of changing market
conditions, and commitment to long-standing investment strategies were key to
the competitive performance achieved by the SunAmerica Income Funds over the
twelve month period ended March 31, 1997. Four of the five SunAmerica Income
Funds outperformed their respective Lipper category averages for the fiscal
year on a cumulative basis. The Tax Exempt Insured Fund slightly
underperformed its category average primarily because of its more conservative
philosophy.
 
MARKET ACTIVITY
 
  Overall, the fiscal year was a difficult one for fixed income investors, as
expectations that the U.S. Federal Reserve Board would officially tighten
monetary policy persistently hung over both the U.S. and international debt
markets.
 
  The period began with real U.S. GDP accelerating to a 4.2% pace,
dramatically slowing in the next quarter to 2.1%, and then picking up again to
3.8% in the fourth calendar quarter of 1996. In the first quarter of 1997,
real GDP was in excess of 3%. The actual inflation picture remained quite
benign throughout. In February, however, there appeared to be a renewal of a
consumer-led economy, as the Consumer Price Index, housing starts, and retail
sales, among other indicators, were all higher than anticipated. Federal
Reserve Board Chairman Alan Greenspan's comments regarding "irrational
exuberance" over market valuations and the possibility of a "preemptive
strike" exacerbated the markets' nervous concerns. Finally, after many months
of speculation and for the first time since January 1996, the Federal Reserve
Board raised the fed funds rate by 0.25% on March 25, 1997.
 
  U.S. GOVERNMENT SECURITIES. U.S. interest rates rose over the period, pushed
both by the rapid pace of economic growth and in anticipation of Fed action.
Market volatility from day to day was high, but the yield spread, from the
beginning of the fiscal period to the end, was very tight. For example, yields
on 30-year Treasuries moved less than 1.0%. This is a strong indication that
investors had already priced in some future tightening. Short-term yields
increased more than long-term yields, leading to a flattening yield curve.
Mortgages outperformed all other fixed income sectors for the fiscal year. As
indicated in our last report, when interest rates rise, prepayment activity
declines, and this, combined with a comparatively low interest rate
environment, led investors to prefer the extra income offered by mortgages
over U.S. Treasuries.
 
  One trend that provided support for the U.S. Treasury market in the face of
rising interest rates was the strength of the U.S. dollar versus most G7
currencies. Foreign investors continue to take advantage of the interest rate
differential and the inherent liquidity offered by dollar denominated assets.
 
  HIGH YIELD CORPORATE SECURITIES. These securities started the fiscal period
with a weak quarter, were strong in the next two, and, similar to other fixed
income sectors, were impacted negatively in the most recent quarter by the
Fed's interest rate hike. Overall, however, high yield products experienced
large cash inflows by individuals, insurance companies and pension plans, as
investors sought the benefits of the favorable supply/demand balance and the
higher returns offered in comparison to U.S. Treasuries. The media and
cyclical industries were strong; the consumer and telecommunications
industries were weak.

  INTERNATIONAL SECURITIES. For most of the fiscal year, the foreign debt
markets underperformed the other fixed income sectors. However, by the first
calendar quarter of 1997, yield spreads widened relative to U.S. Treasuries,
indicating, we believe, the beginning of a cyclical upturn in performance.
Within this sector, our focus continued to be on the Latin American markets.
Mexico and Venezuela were weak, but Argentina and Brazil outperformed, based,
in large part, on anticipation of April 2nd upgrades by Standard & Poor's.
 
  TAX EXEMPT SECURITIES. Municipal securities supply throughout the twelve
month period, both in new issue volume and refunding bonds, was low. This was
due to rising interest rates, a general aura of fiscal conservatism in
Washington, D.C., and relatively strong state and local economies, which
enabled municipalities to use increased tax proceeds and reserve pools, rather
than borrowed money, to pursue projects. Demand, on the other hand, remained
quite strong. This balance, along with an almost 3:1 credit upgrade/downgrade
ratio, was favorable for this sector's performance.
 
INVESTMENT REVIEW
 
  THE U.S. GOVERNMENT SECURITIES AND FEDERAL SECURITIES FUNDS, each with
approximately 1/3 of their portfolio assets invested in premium, higher coupon
mortgages, 1/3 in current coupon, total return-oriented mortgages, and 1/3 in
U.S. Treasuries, both benefited from their weightings in the outperforming
mortgage sector. This "thirds strategy" also enabled us to adjust quickly in
response to a market characterized by high day-to-day volatility and best
taken advantage of through strong trading capabilities. Clearly, this
strategy, along with a basically neutral posture towards the market, worked,
as both Funds ranked in the top third of their respective Lipper category
averages.
 
  In addition to its allocation structure, the outperformance of the U.S.
Government Securities Fund was due to strong security selection. The Fund's
duration ranged from a high of 4.7 years to a low of 4.1 years over the twelve
months and as of March 31, 1997 stood at 4.5 years. Active trading and minor
maturity adjustments contributed to the outperformance of the Federal
Securities Fund. This Fund's duration ranged from 5.8 to 4.8 years over the
twelve months and as of March 31, 1997 stood at 5.3 years. Once an imminent
tightening in monetary policy was virtually certain, the maturities of both
Funds were shortened in March.
 
  THE DIVERSIFIED INCOME AND HIGH INCOME FUNDS, each of which outperformed
their respective Lipper category averages for the annual period, both
benefited most from outstanding sector selection. Determining allocation based
on relative sector value, the Diversified Income Fund was approximately 47%
invested in foreign securities, 37% in high yield U.S. corporate bonds, 4% in
U.S. Treasuries and 12% in cash and other securities on March 31, 1997. Most
of the shift from an underweight to overweight position in foreign debt
securities was made in the first calendar quarter of 1997, as we began to see
a cyclical upturn there. Over half of the Fund's foreign securities are in
Latin America, where industries are maturing, economies are expanding rapidly,
and cash flows on corporate obligations are strengthening, in turn, enhancing
liquidity. We also continue to see opportunities in several nations' sovereign
issues and in the technology industry on a global basis.
 
  The High Income Fund particularly benefited from its overweight position in
the media sector, especially the U.K. cable companies such as Bell Cablemedia
and Videotron, and the broadcaster New World

Communications, which outperformed the sector as a whole. Still, toward the
end of the period, we moved to an underweight position in this sector, as
individual positions were sold when they met their target prices and profits
were redeployed elsewhere. The Fund also benefited from its neutral weightings
in the cyclical and consumer sectors. The telecommunications sector
underperformed, but the Fund remained overweight there, as we continue to see
value in this broad-ranging industry.
 
  THE TAX EXEMPT INSURED FUND maintained its defensive posture and its
commitment to stability of principal. The flattening yield curve and rising
interest rates hurt performance somewhat. However, the Fund's laddered
maturity approach, i.e. buying issues across the yield curve, its lower than
average duration, and its strong emphasis on high credit quality all helped it
produce better than category average returns in three of the four fiscal year
quarters. The Fund increased its exposure to New York issues, based on
improving fundamentals in its local economy, and sold off some Oklahoma
issues, as other municipalities offered more compelling relative returns. As
of March 31, 1997, the Fund was broadly diversified among 31 states, and
approximately 85% of its portfolio assets were invested in insured municipal
bonds.
 
MANAGER OUTLOOK
 
  Looking ahead, we believe the fixed income markets will remain on the
defensive until the U.S. economy moderates. Since the Federal Reserve Board
acted preemptively in March, we do not see any major increase in inflation,
although there is still a fairly strong possibility that the Fed will tighten
monetary policy again by another 0.25%. Still, the level of "real" interest
rates is already close to a historically restrictive level.
 
  Consequently, we believe that the short-term slowing in the fixed income
markets brought about by these interest rate increases will help preserve the
broader economic expansion in place since 1991 and may very well provide
opportunities for bond yields to fall in the second half of 1997. In addition,
we do not believe that the spending patterns of the consumer have staying
power much past the first quarter of the calendar year, which furthers our
positive disposition toward the fixed income markets. We do believe that
volatility of yields within a tight range will continue.
 
  Given this outlook, we anticipate lengthening the maturities of both the
U.S. Government Securities and Federal Securities Funds once there are clear
indicators that the economy has slowed down, the Federal Reserve Board action
is working, and as long as 30-year Treasury rates remain over 7%. We intend to
stay focused on the higher yielding international markets in the Diversified
Income Fund and on the telecommunications sector in the High Income Fund. As
for the investments of the Tax Exempt Insured Fund, we believe three factors
bode particularly well. The first is continuing budgetary consciousness in
Washington regarding both balancing the budget and keeping spending cuts to a
minimum. The second is a longer-term demographic trend that favors aging baby-
boomers seeking to emphasize protection over creation of wealth. The third is
that technical factors that drive the municipal market continue to be in our
favor.
 
  In all of the SunAmerica Income Funds, what is perhaps most important is our
long-standing commitment to our top-down, issue-specific, value-oriented
strategies, carried out in a disciplined manner consistent with current market
conditions and interest rate forecasts. The wisdom of this philosophy has been
proven in the performance of our Funds over time.

 SUNAMERICA INCOME FUNDS
 NOTES TO FINANCIAL STATEMENTS -- March 31, 1997
Note 1. Organization
 
  SunAmerica Income Funds is an open-end diversified management investment
  company organized as a Massachusetts business trust (the "Trust"). It
  currently consists of five different investment series (each, a "Fund" and
  collectively, the "Funds"). Each Fund is a separate series of the Trust
  with distinct investment objectives and/or strategies. Each Fund is managed
  by SunAmerica Asset Management Corp. (the "Adviser" or "SAAMCo"), an
  indirect wholly owned subsidiary of SunAmerica Inc. An investor may invest
  in one or more of the following Funds: SunAmerica U.S. Government
  Securities Fund, SunAmerica Federal Securities Fund, SunAmerica Diversified
  Income Fund, SunAmerica High Income Fund and SunAmerica Tax Exempt Insured
  Fund. The Funds are considered to be separate entities for financial and
  tax reporting purposes. The investment objectives for each of the Funds are
  as follows:
  U.S. Government Securities Fund seeks high current income consistent with
  relative safety of capital by investing primarily in securities issued or
  guaranteed by the U.S. government, or any agency or instrumentality
  thereof.
  Federal Securities Fund seeks current income, with capital appreciation as
  a secondary objective, by investing primarily in securities issued or
  guaranteed by the U.S. government or any agency or instrumentality thereof.
  Diversified Income Fund seeks a high level of current income consistent
  with moderate investment risk, with preservation of capital as a secondary
  objective.
  High Income Fund seeks maximum current income by investing primarily in
  high-yield, high-risk corporate bonds.
  Tax Exempt Insured Fund seeks a high level of current income exempt from
  Federal income taxes as is consistent with preservation of capital.
 
  Each Fund currently offers two classes of shares. Class A shares are
  offered at net asset value per share plus an initial sales charge. Class B
  shares are offered without an initial sales charge, although a declining
  contingent sales charge may be imposed on redemptions made within six years
  of purchase. Additionally, any purchases of Class A shares in excess of
  $1,000,000 will be subject to a contingent deferred sales charge on
  redemptions made within one year of purchase. Class B shares of each Fund
  convert automatically to Class A shares on the first business day of the
  month following the seventh anniversary of the issuance of such Class B
  shares and at such time will be subject to the lower distribution fee
  applicable to Class A shares. Each class of shares bears the same voting,
  dividend, liquidation and other rights and conditions and each makes
  distribution and account maintenance and service fee payments under a
  distribution plan pursuant to Rule 12b-1 under the Investment Company Act
  of 1940 (the "1940 Act") except that Class B shares are subject to higher
  distribution fee rates.
 
Note 2. Significant Accounting Policies
 
  The preparation of financial statements in accordance with generally
  accepted accounting principles requires management to make estimates and
  assumptions that affect the reported amounts and disclosures in the
  financial statements. Actual results could differ from these estimates.

 SUNAMERICA INCOME FUNDS
 NOTES TO FINANCIAL STATEMENTS -- March 31, 1997 -- (continued)
 
  The following is a summary of the significant accounting policies followed
  by the Funds in the preparation of their financial statements:
 
  SECURITY VALUATIONS: Securities that are actively traded in the over-the-
  counter market, including listed securities for which the primary market is
  believed by the Adviser to be over-the-counter, are valued at the quoted
  bid price provided by principal market makers. Securities listed on the New
  York Stock Exchange ("NYSE") or other national securities exchanges, are
  valued on the basis of the last sale price on the exchange on which they
  are primarily traded. If there is no sale on that day, then securities are
  valued at the closing bid price on the NYSE or other primary exchange for
  that day. However, if the last sale price on the NYSE is different than the
  last sale price on any other exchange, the NYSE price is used. Securities
  that are traded on foreign exchanges are ordinarily valued at the last
  quoted sales price available before the time when the assets are valued. If
  a securities price is available from more than one foreign exchange, a Fund
  uses the exchange that is the primary market for the security. Values of
  portfolio securities primarily traded on foreign exchanges are already
  translated into U.S. dollars when received from a quotation service.
  Options traded on national securities exchanges are valued as of the close
  of the exchange on which they are traded. Futures and options traded on
  commodities exchanges are valued at their last sale price as of the close
  of such exchange. The Funds may make use of a pricing service in the
  determination of their net asset values. The preceding procedures need not
  be used to determine the value of debt securities owned by a Fund if, in
  the opinion of the Trustees, some other method would more accurately
  reflect the fair market value of such debt securities in quantities owned
  by such Fund. Securities for which market quotations are not readily
  available and other assets are valued at fair value as determined pursuant
  to procedures adopted in good faith by the Trustees. Short-term investments
  which mature in less than 60 days are valued at amortized cost, if their
  original maturity was 60 days or less, or by amortizing their value on the
  61st day prior to maturity, if their original term to maturity exceeded 60
  days.
 
  REPURCHASE AGREEMENTS: The Funds, along with other affiliated registered
  investment companies, transfer uninvested cash balances into a joint
  account, the daily aggregate balance of which is invested in one or more
  repurchase agreements collateralized by U.S. Treasury or federal agency
  obligations. The Funds' custodian takes possession of the collateral
  pledged for investments in repurchase agreements. The underlying collateral
  is valued daily on a mark to market basis to ensure that the value,
  including accrued interest, is at least equal to the repurchase price. In
  the event of default of the obligation to repurchase, a Fund has the right
  to liquidate the collateral and apply the proceeds in satisfaction of the
  obligation. If the seller defaults and the value of the collateral declines
  or if bankruptcy proceedings are commenced with respect to the seller of
  the security, realization of the collateral by the Fund may be delayed or
  limited.
 
  Pursuant to exemptive relief granted by the Securities and Exchange
  Commission, the Funds are permitted to participate in joint repurchase
  agreement transactions with other affiliated investment companies.

  SECURITIES TRANSACTIONS, INVESTMENT INCOME, EXPENSES, DIVIDENDS AND
  DISTRIBUTIONS TO SHAREHOLDERS: Securities transactions are recorded on a
  trade date basis. Realized gains and losses on sales of investments are
  calculated on the identified cost basis. Interest income is recorded on the
  accrual basis; dividend income is recorded on the ex-dividend date. The
  Funds do not amortize market premiums (except for Tax Exempt Insured Fund)
  or accrete market discounts (except for Diversified Income Fund) except
  original issue discounts for which amortization is required for federal
  income tax purposes.
 
  Net investment income, other than class specific expenses, and realized and
  unrealized gains and losses are allocated daily to each class of shares
  based upon the relative net asset value of outstanding shares of each class
  of shares at the beginning of the day (after adjusting for the current
  capital share activity of the respective class).
 
  Expenses common to all Funds are allocated among the Funds based upon their
  relative net asset values or other appropriate allocation methods.
 
  Dividends from net investment income are accrued daily and paid monthly.
  Capital gain distributions, if any, are paid annually. The amount of
  dividends and distributions from net investment income and net realized
  capital gains 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. Net investment income/loss, net realized gain/loss, and
  net assets were not affected.

  For the year ended March 31, 1997, the following reclassifications arising
  from book/tax differences were primarily the result of market discount and

  INVESTMENT SECURITIES LOANED: During the year ended March 31, 1997, U.S.
  Government Securities Fund, Federal Securities Fund and Diversified Income
  Fund participated in securities lending with qualified brokers. In lending
  portfolio securities to brokers the Funds receive cash as collateral
  against the loaned securities, which must be maintained at not less than
  102% of the market value of the loaned securities during the period of the
  loan. To the extent income is earned on the cash collateral invested, it is
  recorded as interest income. Alternatively, an interest expense is recorded
  on the books when the cash collateral from the securities on loan is used
  to cover an overdraft. As with other extensions of credit, should the
  borrower of the securities fail financially, the Funds may bear the risk of
  delay in recovery or may be subject to replacing the loaned securities by
  purchasing them with the cash collateral held, which may be less than 100%
  of the market value of such securities at the time of replacement.
 
  At March 31, 1997, U.S. Government Securities Fund and Federal Securities
  Fund have loaned securities having a value of $24,019,562 and $4,803,913,
  respectively, and held cash collateral of $24,000,000 and $4,800,000,
  respectively, for these loans.
 
  FOREIGN CURRENCY TRANSLATION: The books and records of the Funds are
  maintained in U.S. dollars. Assets and liabilities denominated in foreign
  currencies and commitments under forward foreign currency contracts are
  translated into U.S. dollars at the mean of the quoted bid and asked prices
  of such currencies against the U.S. dollar.
 
  The Fund does not isolate that portion of the results of operations arising
  as a result of changes in the foreign exchange rates from the changes in
  the market prices of securities held at fiscal year-end. The Fund does not
  isolate the effect of changes in foreign exchange rates from the changes in
  the market prices of portfolio securities sold during the year.
 
  Realized foreign exchange gains and losses on other assets and liabilities
  and change in unrealized foreign exchange gains and losses on other assets
  and liabilities include foreign exchange gains and losses from currency
  gains or losses realized between the trade and settlement dates of
  securities transactions, forward currency contracts, dividends received,
  the difference between the amounts of interest, discount and foreign
  withholding taxes recorded on the Fund's books and the U.S. dollar

 NOTES TO FINANCIAL STATEMENTS -- March 31, 1997 -- (continued)
  equivalent amounts actually received or paid and changes in the unrealized
  foreign exchange gains and losses relating to other assets and liabilities
  arising as a result of changes in the exchange rates.
 
  FUTURES CONTRACTS: A futures contract is an agreement between two parties
  to buy and sell a financial instrument at a set price on a future date.
  Upon entering into such a contract the Funds are required to pledge to the
  broker an amount of cash or U.S. government securities equal to the minimum
  "initial margin" requirements of the exchange on which the futures contract
  is traded. The contract amount reflects the extent of a Fund's exposure in
  these financial instruments. The Funds' activities in futures contracts are
  for hedging purposes and are conducted through regulated exchanges which do
  not result in counterparty credit risks. A Fund's participation in the
  futures markets involves certain risks, including imperfect correlation
  between movements in the price of futures contracts and movements in the
  price of the securities hedged or used for cover. Pursuant to a contract
  the Funds agree to receive from or pay to the broker an amount of cash
  equal to the daily fluctuation in value of the contract. Such receipts or
  payments are known as "variation margin" and are recorded by the Funds as
  unrealized appreciation or depreciation. When a contract is closed, the
  Funds record a realized gain or loss equal to the difference between the
  value of the contract at the time it was opened and the value at the time
  it was closed.
 
Note 3. Investment Advisory and Management Agreement, Distribution Agreement
and Service Agreement
 
  The Trust, on behalf of each Fund, has an Investment Advisory and
  Management Agreement (the "Agreement") with SAAMCo. Under the Agreement,
  SAAMCo provides continuous supervision of a Fund's portfolio and
  administers its corporate affairs, subject to general review by the
  Trustees. In connection therewith, SAAMCo furnishes the Funds with office
  facilities, maintains certain of the Funds' books and records, and pays the
  salaries and expenses of all personnel, including officers of the Funds,
  who are employees of SAAMCo and its affiliates.
 
  The Funds pay SAAMCo a monthly investment advisory and management fee
  calculated daily at the following annual percentages of each Fund's net
  assets:

  The Trust, on behalf of each Fund, has a Distribution Agreement with
  SunAmerica Capital Services, Inc. ("SACS" or "Distributor"), an indirect
  wholly owned subsidiary of SunAmerica Inc. Each Fund has adopted a
  Distribution Plan (the "Plan") in accordance with the provisions of Rule
  12b-1 under the 1940 Act. Rule 12b-1 under the 1940 Act permits an
  investment company directly or indirectly to pay expenses associated with
  the distribution of its shares ("distribution expenses") in accordance with
  a plan adopted by the investment company's board of trustees and approved
  by its shareholders. Pursuant to such rule, the Trustees and the
  shareholders of each class of shares of each Fund have adopted Distribution
  Plans, hereinafter referred to as the "Class A Plan" and the "Class B
  Plan." In adopting the Class A Plan and the Class B Plan, the Trustees
  determined that there was a reasonable likelihood that each such Plan would
  benefit the Trust and the shareholders of the respective class. The sales
  charge and distribution fees of a particular class will not be used to
  subsidize the sale of shares of any other class.
 
  Under the Class A Plan and Class B Plan, the Distributor receives payments
  from a Fund at an annual rate of up to 0.10% and .75%, respectively, of
  average daily net assets of such Fund's Class A and Class B shares to
  compensate the Distributor and certain securities firms for providing sales
  and promotional activities for distributing that class of shares. The
  distribution costs for which the Distributor may be reimbursed out of such
  distribution fees include fees paid to broker-dealers that have sold Fund
  shares, commissions, and other expenses such as those incurred for sales
  literature, prospectus printing and distribution and compensation to
  wholesalers. It is possible that in any given year the amount paid to the
  Distributor under the Class A Plan or Class B Plan may exceed the
  Distributor's distribution costs as described above. The Distribution Plans
  provide that each class of shares of each Fund may also pay the Distributor
  an account maintenance and service fee at the annual rate of up to 0.25% of
  the aggregate average daily net assets of such class of shares for payments
  to broker-dealers for providing continuing account maintenance.
  Accordingly, for the year ended March 31, 1997, SACS received fees (see
  Statement of Operations) based upon the aforementioned rates (of which
  $6,176 and $11,034 was reimbursed to the U.S. Government Securities Fund
  Class A and High Income Fund Class B, respectively).
 
  SACS receives sales charges on each Fund's Class A shares, portions of
  which are reallowed to affiliated broker-dealers and non-affiliated broker-
  dealers. SACS also receives the proceeds of contingent deferred sales
  charges paid by investors in connection with certain redemptions of Class B
  fund shares. SACS has advised the Funds that for the year ended March 31,
  1997, the proceeds received from Class A sales (and paid out to affiliated
  and non-affiliated broker-dealers) and Class B redemptions are as follows:

 NOTES TO FINANCIAL STATEMENTS -- March 31, 1997 -- (continued)
 
  Capital losses and currency losses after October 31 within the taxable year
  are deemed to arise on the first business day of the Funds' next taxable
  year. Accordingly, the U.S. Government Securities Fund and Federal
  Securities Fund, incurred and elected to defer capital losses of $178,567
  and $89,186, respectively, to the taxable year ended March 31, 1998. To the
  extent these losses are permitted under regulations to be used to offset
  future gains, it is probable that the gains so offset will not be
  distributed.
 
  At March 31, 1997, U.S. Government Securities Fund, Federal Securities
  Fund, Diversified Income Fund, High Income Fund and Tax Exempt Insured Fund
  had capital loss carryforwards of $36,791,157, $1,045,533, $29,832,034,
  $37,606,003 and $6,547,732, respectively, which were available to the
  extent provided in regulations and which will expire between 1998-2005.
  Some of these capital loss carry-forwards were acquired from mergers and
  may be subject to certain limitations. To the extent that these carryover
  losses are used to offset future capital gains, it is probable that the
  gains so offset will not be distributed.
 
  Diversified Income Fund, High Income Fund and Tax Exempt Insured Fund
  utilized capital loss carryforwards of $2,011,740, $7,129,273 and
  $2,316,366, respectively, to offset the Funds' net taxable gains realized
  and recognized in the year ended March 31, 1997.

 NOTES TO FINANCIAL STATEMENTS -- March 31, 1997 -- (continued)
  January 1, 1993 for the unaffiliated Trustees. The Retirement Plan provides
  generally that if an unaffiliated Trustee who has at least 10 years of
  consecutive service as a Disinterested Trustee of any of the SunAmerica
  mutual funds (an "Eligible Trustee") retires after reaching age 60 but
  before age 70 or dies while a Trustee, such person will be eligible to
  receive a retirement or death benefit from each SunAmerica mutual fund with
  respect to which he or she is an Eligible Trustee. As of each birthday,
  prior to the 70th birthday, but in no event for a period greater than 10
  years, each Eligible Trustee will be credited with an amount equal to  50%
  of his or her regular fees (excluding committee fees) for services as a
  Disinterested Trustee of each SunAmerica mutual fund for the calendar year
  in which such birthday occurs. In addition, an amount equal to 8.5% of any
  amounts credited under the preceding clause during prior years is added to
  each Eligible Trustee's Account until such Eligible Trustee reaches his or
  her 70th birthday. An Eligible Trustee may receive any benefits payable
  under the Retirement Plan, at his or her election, either in one lump sum
  or in up to fifteen annual installments. As of March 31, 1997, U.S.
  Government Securities Fund, Federal Securities Fund, Diversified Income
  Fund, High Income Fund and Tax Exempt Insured Fund had accrued $54,424,
  $5,542, $11,104, $12,341 and $12,962, respectively, for the Retirement
  Plan, which is included in accrued expenses on the Statement of Assets and
  Liabilities and for the year ended March 31, 1997 expensed $23,804, $2,660,
  $5,211, $6,390 and $6,266, respectively, for the Retirement Plan, which is
  included in Trustees' fees and expenses on the Statement of Operations.

 SUNAMERICA INCOME FUNDS
 REPORT OF INDEPENDENT ACCOUNTANTS
To the Trustees and Shareholders of SunAmerica Income Funds
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of SunAmerica U.S. Government
Securities Fund, SunAmerica Federal Securities Fund, SunAmerica Diversified
Income Fund, SunAmerica High Income Fund and SunAmerica Tax Exempt Insured Fund
(constituting SunAmerica Income Funds, hereafter referred to as the "Fund") at
March 31, 1997, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
indicated, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits, which included confirmation of
securities at March 31, 1997 by correspondence with the custodian and brokers

 COMPARISONS: PORTFOLIOS VS. INDICES
 
  As required by the Securities and Exchange Commission, the following graphs
  compare the performance of a $10,000 investment in the SunAmerica Income
  Funds' portfolios to a similar investment in a broad based index. It is
  important to note that the SunAmerica Income Funds are professionally
  managed mutual funds while the indices are not available for investment and
  are unmanaged. The comparison is shown for illustrative purposes only. The
  graphs present the performance of the class of that particular Fund which
  has been in existence the longest. The performance of the other class will
  vary based upon the difference in sales charges and fees assessed to
  shareholders of that class. The maximum sales charge for Class A is 4.75%
  of the public offering price. The maximum contingent deferred sales charge
  for Class B is 4.0% and is reduced to 0% after 6 years. Both Class A and
  Class B bear ongoing 12b-1 distribution and service fees.

With a cumulative total return of 3.98%, the U.S. Government Securities Fund
Class A outperformed its group average's performance of 3.48% (tracked by Lipper
Analytical Service) for the twelve months ended March 31, 1997. This strong
performance was due to superior security selection more than to adjustment of
portfolio characteristics such as maturity and duration. The Fund underperformed
relative to the Lehman Brothers Government Bond Index, which is an unmanaged
index and not available as an investment.

Active trading and maturity adjustments benefited this Fund's annual
performance. The Fund Class A had a cumulative total return of 5.40%,
outperforming its Lipper category average of 4.76%. As you can see in the chart
to the left, over time, the Fund has also closely tracked its benchmark, the
Salomon Brothers GNMA Index, which is an unmanaged index that tracks performance
of the GNMA portion of the U.S. Government bond market. The Fund's Class A
shares ranked 10 out of 51 funds in its comparative Lipper category for the
twelve months.

The Diversified Income Fund Class A had a cumlulative total return of 11.43% for
the twelve months ended March 31, 1997, as compared to 10.52% for its Lipper
category average. This outperformance is primarily attributable to superior
sector selection and a shift from an overweighting in corporate bonds one year
ago to an overweighting in foreign debt securities at the end of this fiscal
year. Because the Fund invests in several sectors of the bond market, it is not
compared to any one benchmark. The Fund outperformed, for the twelve months
ended March 31, 1997, the J.P. Morgan Global Government Bond Index and closely
tracked the Lehman Brothers Government Bond Index. It underperformed the Salomon
Brothers High Yield Market Index and the Merrill Lynch High Yield Index. The
Fund's objective has been a high level of current income consistent with
moderate investment risk since late 1992; therefore, performance comparisons
since the Fund's inception in April 1991 may not be relevant.

Benefiting primarily from superior sector selection, the High Income Fund Class
A achieved a cumulative total return of 11.46% for the fiscal year ended March
31, 1997, as compared to 11.35% for its Lipper category average. The Fund
underperformed the Salomon Brothers and Merrill Lynch High Yield Market Indices,
both unmanaged indices of high yield bonds. Given the flattening yield curve,
our outlook for this asset class is somewhat tempered; however, careful credit
analysis, constant monitoring of the financial markets, and a well-diversified
portfolio should still enable us to seek maximum current income with less risk
than normally associated with owning high yield securities.

For the year ended March 31, 1997, the Tax Exempt Insured Fund Class A had a
cumulative total return of 4.24%, as compared to 4.35% for its Lipper category
average. The Fund also underperformed the return for the Lehman Brothers
Municipal Bond Index, an unmanaged index consisting of municipal bonds that may
not be insured as to the timely payment of principal and interest. In contrast,
at least 65% of the holdings of the Tax Exempt Insured Fund are insured under
normal conditions. In fact, on March 31, 1997, approximately 85% of the Fund's
holdings were insured. The remainder is invested in investment grade bonds or
bonds of comparable quality. This Fund continues to be conservatively managed,
as it seeks as high a level of current income exempt from Federal taxes as is
consistent with preservation of capital.
