      FROM THE CHAIRMAN
            State Street Research

      The U.S. economy grew at a solid pace during the six-month period from
      April 1, 2004 to September 30, 2004. Gross Domestic Product (GDP), a
      common measure of economic growth, rose at a pace of more than 3.5% for
      the first half of 2004. Estimates for second half suggest that the pace of
      growth could have picked up somewhat, as the US economy remains on solid
      ground.

      Consumer confidence wavered early in the period as the number of new jobs
      added to the economy fell below expectations. When the job picture
      brightened in April and May, consumer confidence tracked higher. More than
      1.2 million jobs were added to the U.S. economy in the spring, and the
      quality of new jobs improved, as reported by the U.S. Labor Department.
      However, caution returned on disappointing jobs reports in July and August
      and consumer confidence pulled back.

      Yet, consumers continued to fuel the economy, pumping dollars into the
      retail and housing markets. Sales of new and existing homes soared as
      homebuyers anticipated higher mortgage rates ahead. Corporate profits
      continued to rise, making it easier for companies to increase spending,
      especially on information technology, electronic equipment and new jobs.

      As the period wore on, it became clear that the days of record-low
      short-term interest rates were coming to an end. In June, the Federal
      Reserve Board raised the federal funds rate from 1.0% to 1.25%. The Fed
      raised this key short-term rate to 1.5% in August and to 1.75% in
      September. These increases had little or no impact on the financial
      markets because they had been widely anticipated and because the Fed has
      signaled that it will take a measured approach to raising rates as the
      economic recovery matures.

      Stocks Stumble as Bonds Edge Higher

      After a relatively positive start to the calendar year, a host of worries
      stopped the major stock market indexes in their tracks. Investors grew
      more cautious about interest rates, rising energy prices, the threat of
      terrorist attacks and the outcome of the presidential election and stocks
      retreated. Value stocks held up considerably better than growth stocks.
      The energy sector was the stock market's strongest performer.

      High-yield bonds continued to lead the bond market. Most other sectors of
      the bond market eked out modest positive returns as the yield on the
      benchmark 10-year U.S. Treasury bond moved lower in the final months of
      the period. Yields and bond prices move in opposite directions.

      Looking Ahead

      Any time the financial markets deliver negative returns, it is
      disheartening for investors. However, the seeds of a new market rally are
      often sown in periods of weakness and decline. With a diversified
      portfolio and a long-term perspective on the markets, it is easier to
      weather periods of volatility--and more likely that you may reap the
      potential benefits in better times. We urge you to talk to your investment
      professional about your investment plan. And we look forward to helping
      you achieve your long-term financial goals.

      Sincerely,

      /s/ Richard S. Davis

          PERFORMANCE

                       Discussion as of September 30, 2004

How State Street Research Asset Allocation Fund Performed State Street Research
Asset Allocation Fund (Class A shares, without sales charge) returned -0.94% for
the six-month period ended September 30, 2004. It underperformed its peer group,
the Lipper Flexible Portfolio Funds Average, which was -0.72% for the period.
The fund also underperformed the S&P 500/Lehman Brothers Blended Index, which
returned -0.19% for the same period.

Reasons for the Fund's Performance

The broad equity markets struggled during the six-month period, with growth
stocks experiencing the largest downturn. Bonds recovered during the third
calendar quarter, resulting in positive returns for the year to date.

Within the equity portion of the portfolio, small-cap growth stocks had the
largest negative impact on returns because the sector suffered the largest
declines during the period. However, an increased exposure to large-cap value
shares helped the fund's return as value stocks led the market. In addition, the
fund's inflation-sensitive holdings aided return, as they benefited from rising
oil prices. Finally, a modest international equity allocation was detrimental,
as the Japanese stock market continued to lose ground.

In the fixed income portfolio, high-yield and emerging markets exposure had the
greatest positive impact on returns. The high-yield sector benefited from a
recovery in corporate earnings and a decline in the expected default rate to
3.0%. The outlook for emerging markets debt also improved. Meanwhile, we
slightly increased our high-grade bond allocation, which helped performance.

Looking Ahead

We continue to emphasize equities over bonds, ending the period with a 63%
stocks/37% bonds allocation. That represents a slight decrease in our exposure
to equities and a slight increase in bonds, reflecting our view that corporate
profit growth has decelerated and the stock market outlook remains uncertain.

In the equity portfolio, we continue to favor large-cap stocks over small-cap,
and value issues over growth. We believe that business prospects for growth
stocks, especially in the technology area, remain weak, and we continue to find
investment opportunities among value stocks. The fund has maintained its modest
position in international equities.

Within fixed income, we remain invested in both high-yield and emerging markets
debt, as we believe they offer the highest return potential.

A Word about Risk

When investing in stocks, the fund may experience sudden or unpredictable drops
in value and periods of lackluster performance. When investing in bonds, the
fund takes on the risks of bond investing, including the tendency for bond
prices to fall when interest rates rise. Investments in foreign derivative
securities are subject to economic and currency risk. The fund may not correctly
anticipate the relative performance of different asset categories over specific
time periods.

Because financial markets and mutual fund strategies are constantly evolving, it
is possible that the fund's holdings, market stance, outlook for various
industries or securities and other matters discussed in this report have changed
since this information was prepared. Portfolio changes should not be considered
recommendations for action by individual investors.

no guarantee of future results. Current performance may be lower or higher than
the performance data quoted herein. For the most recent month-end performance
results, visit our website at www.ssrfunds.com. The fund's share price, yield
and return will fluctuate, and you may have a gain or loss when you sell your
shares. All returns assume reinvestment of capital gains distributions and
income dividends at net asset value. The returns shown do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares.

Average annual total return without sales charge does not reflect the maximum
applicable sales charges. If the applicable sales charges were deducted,
performance results would be lower.

Average Annual Total return at maximum applicable sales charge reflects a
maximum 5.75% Class A share front-end sales charge, or 5% Class B or B(1) share
or 1% Class C share contingent deferred sales charge, where applicable.

Performance for Class B(1) shares reflects Class B share performance through
December 31, 1998, and Class B(1) performance thereafter. If the returns for
Class B(1) shares had reflected their current service/distribution (Rule 12b-1)
fees for the entire period, these returns would have been lower.

Class S shares, offered without sales charge, are available through certain
employee benefit plans and special programs.

The Lipper Flexible Portfolio Funds Average shows the performance of a category
of mutual funds with similar goals. The Lipper average shows you how well the
fund has done compared to competing funds.

 * Expenses are equal to the fund's annualized expense ratio multiplied by the
   average account value over the period, multiplied by the number of days in
   the period and then divided by the number of days in the year.

About Your Fund Expenses

As a fund shareholder, you incur two types of costs: (1) Transaction costs,
which include sales charges, and (2) ongoing expenses, which include management
fees, service/distribution fees (12b-l) and "other" expenses. The examples below
illustrate the ongoing cost in dollars of investing in the fund and allow you to
compare these costs with the expenses of other funds. The examples are based on
a $1,000 investment at the beginning of the period and held for the entire
period from March 31, 2004 to September 30, 2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number shown for your
fund under the column "Expenses Paid during the Period".

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending balance and expenses paid during the period. To
compare your fund's ongoing expenses with those of other funds, simply compare
this 5% hypothetical example with the hypothetical examples shown in the
shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight and help
you compare ongoing costs only and do not reflect transactional expenses such as
sales charges, which would result in higher total expenses. It should also be
noted that, for certain funds, expenses have been subsidized or reduced through
expense offset arrangements, which reduces costs for shareholders. Generally,
the fund expects that the expense subsidy or expense offset arrangement will
continue although there is no guarantee that it will. Please see the fund's
prospectus for more information.

Notes to Unaudited Financial Statements
- --------------------------------------------------------------------------------
September 30, 2004


Note 1
State Street Research Asset Allocation Fund is a series of State Street Research
Income Trust (the "Trust"), which is organized as a Massachusetts business
trust, and is registered under the Investment Company Act of 1940, as amended,
as an open-end management investment company. The Trust consists presently of
two separate funds: State Street Research Asset Allocation Fund and State Street
Research High Income Fund.

The investment objective of the fund is to seek a high total return while
attempting to limit investment risk and preserve capital. To achieve its
investment objective, the fund uses an asset allocation strategy, investing in
varying percentages of its portfolio in three major categories: stocks, bonds
and, to a lesser extent, money market instruments. Drawing on its analysis of
financial trends and market conditions, the investment manager monitors and
adjusts those allocations from time to time. The fund has wide flexibility in
the relative weightings given to each category; however, it intends to remain
diversified across categories.

The fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 5.75% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) shares pay annual service and
distribution fees of 1.00% and automatically convert into Class A shares (which
pay lower ongoing expenses) at the end of eight years. Class B(1) shares are
subject to a contingent deferred sales charge on certain redemptions made within
six years of purchase. Class B shares are offered only to current shareholders
through reinvestment of dividends and distributions or through exchanges from
existing Class B accounts of State Street Research funds. Currently, the annual
service and distribution fees paid by Class B shares have been voluntarily
reduced to 0.00%. Class B shares automatically convert into Class A shares at
the end of eight years. Class B shares are subject to a contingent deferred
sales charge on certain redemptions made within five years of purchase. Class C
shares are subject to a contingent deferred sales charge of 1.00% on any shares
redeemed within one year of their purchase, and also pay annual service and
distribution fees of 1.00%. Class S shares are only offered through certain
retirement accounts, advisory accounts of State Street Research & Management
Company (the "Adviser"), an investment management subsidiary of MetLife, Inc.
("MetLife"), and special programs. No sales charge is imposed at the time of
purchase or redemption of Class S shares. Class S shares do not pay any service
or distribution fees. The fund's expenses are borne prorata by each class,
except that each class bears expenses, and has exclusive voting rights with
respect to provisions of the plans of distribution, related specifically to that
class. Income, expenses (other than service and distribution fees), and
unrealized and realized gains or losses on investments are allocated to each
class of shares based on its relative net assets. The Trustees declare separate
dividends on each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation

Values for listed equity securities reflect final sales on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("Nasdaq") system are valued at closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Fixed income securities are valued by a pricing service, which
utilizes market transactions, quotations from dealers and various relationships
among securities in determining value. Short-term securities maturing within
sixty days are valued at amortized cost. In the event that the market quotations
for a portfolio instrument are not deemed to be readily available, the
Investment Adviser's Valuation Committee determines the fair value for such
portfo-

lio instrument. The fair value of any such portfolio instruments are determined
based upon a consideration of all available facts and information. The fair
valuation of a restricted portfolio instrument reflects the inherent worth of
the portfolio instrument, without regard to the restrictive feature, adjusted
for any diminution in value resulting from the restrictive feature. The
Investment Adviser and the Custodian also monitor domestic and foreign markets
and news information for any developing events that may have an impact on the
valuation of portfolio instruments. Such monitoring includes general market news
and financial market information sources currently utilized in making investment
decisions, trading and investment personnel located abroad, foreign regional
brokers, and/or foreign custodians. The value assigned to these securities is
based upon available information at the time, and does not necessarily represent
the amount which might ultimately be realized upon sale.

B. Forward Contracts and Foreign Currencies
The fund enters into forward foreign currency exchange contracts in order to
hedge its exposure to changes in foreign currency exchange rates on its foreign
portfolio holdings and to hedge certain purchase and sale commitments
denominated in foreign currencies. A forward foreign currency exchange contract
is an obligation by the fund to purchase or sell a specific currency at a future
date, which may be any fixed number of days from the origination date of the
contract. Forward foreign currency exchange contracts establish an exchange rate
at a future date. These contracts are transferable in the interbank market
conducted directly between currency traders (usually large commercial banks) and
their customers. Risks may arise from the potential inability of a counterparty
to meet the terms of a contract and from unanticipated movements in the value of
foreign currencies relative to the U.S. dollar. The aggregate principal amount
of forward currency exchange contracts is recorded in the fund's accounts. All
commitments are marked-to-market at the applicable transaction rates resulting
in unrealized gains or losses. The fund records realized gains or losses at the
time the forward contracts are extinguished by entry into a closing contract or
by delivery of the currency. Neither spot transactions nor forward currency
exchange contracts eliminate fluctuations in the prices of the fund's portfolio
securities or in foreign exchange rates, or prevent loss if the price of these
securities should decline.

C. Security Transactions

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered.

As part of the custodian contract between the custodian bank and the fund, the
custodian bank has a lien on the securities of the fund to the extent permitted
by the fund's investment restriction to cover any advances made by the custodian
bank for the settlement of securities purchased by the fund. At September 30,
2004, the payable to the custodian bank of $250,026 represents the amount due
for cash advance for the settlement of the security purchased.

D. Net Investment Income

Net investment income is determined daily and consists of interest and dividends
accrued and discount earned, less the estimated daily expenses of the fund.
Interest income is accrued daily as earned. Dividend income is accrued on the
ex-dividend date. All discounts/premiums are accreted/amortized. Certain fixed
income and equity securities held by the fund pay interest or dividends in the
form of additional securities (payment-in-kind securities). Interest income on
payment-in-kind fixed income securities is recorded using the effective-interest
method. The fund is charged for expenses directly attributable to it, while
indirect expenses are allocated between both funds in the Trust.

E. Dividends

Dividends from net investment income are declared and paid or reinvested
quarterly. Net realized capital gains, if any, are distributed annually, unless
additional distributions are required for compliance with applicable tax
regulations.

Income dividends and capital gains distributions are determined in accordance
with federal income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
due to differing treatments for wash sale deferrals.

F. Federal Income Taxes

No provision for federal income taxes is necessary because the fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods.

G. Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of income and expenses during
the reporting period. Actual results could differ from these estimates.

H. Securities Lending

The fund may seek additional income by lending portfolio securities to qualified
institutions. The fund will receive cash or securities as collateral in an
amount equal to at least 100% of the current market value of any loaned
securities plus accrued interest. By reinvesting any cash collateral it receives
in these transactions, the fund could realize additional gains and losses. If
the borrower fails to return the securities and the value of the collateral has
declined during the term of the loan, the fund will bear the loss. At September
30, 2004, the value of the securities loaned and the value of collateral were
$61,488,625 and $63,355,290 (consisting entirely of cash collateral invested in
State Street Navigator Securities Lending Prime Portfolio), respectively. During
the six months ended September 30, 2004, income from securities lending amounted
to $79,641.

I. Futures

The fund may enter into futures contracts as a hedge against unfavorable market
conditions and to enhance income. The fund will not purchase any futures
contract if, after such purchase, more than one-third of net assets would be
represented by long future contracts. The fund will limit its risks by entering
into a futures position only if it appears to be a liquid investment.

Upon entering into a futures contract, the fund deposits with the selling broker
sufficient cash or U.S. government securities to meet the minimum "initial
margin" requirements. Thereafter, the fund receives from or pays to the broker
cash or U.S. government securities equal to the daily fluctuation in value of
the contract ("variation margin"), which is recorded as unrealized gain or loss.
When the contract is closed, the fund records a realized gain or loss equal to
the difference between the value of the contract at the time it has opened and
the value at the time it was closed.

The potential risk to the fund is that the change in value of futures contracts
may not correspond to the change in value of the hedged instruments. In
addition, losses may arise in changes from the value of the underlying
instruments, if there is an illiquid secondary market for the contracts, or if
the counterparty to the contract is unable to perform.

J. Options

The fund may use options to hedge against changes in values of securities the
fund owns or expects to purchase. Writing puts or buying calls tends to increase
the fund's exposure to the underlying instrument and writing calls or buying
puts tends to decrease the fund's exposure to the underlying instrument, or
hedge other fund investments.

For options purchased to hedge the fund's investments, the potential risk to the
fund is that the change in value of options contracts may correspond to the
change in value of the hedged instruments. In addition, losses may arise from
changes in the value of the underlying instruments, if there is an illiquid
secondary market, or if the counter party is unable to perform. The maximum loss
for purchased options is limited to the premium initially paid for the option.
For options written by the fund, the maximum loss is not limited to the premium
initially received for the option.

Note 2
The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.75% of the first $500 million of net
assets annually, 0.70% of the next $500 million, and 0.65% of any amount over $1
billion. In consideration of these fees, the Adviser furnishes the fund with
management, investment advisory, statistical and research facilities and
services. The Adviser also pays all salaries, rent and certain other expenses of
management. During the six

20



months ended September 30, 2004, the fees pursuant to such agreement amounted to
$2,459,507.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), provides certain shareholder services to the fund such as
responding to inquiries and instructions from investors with respect to the
purchase and redemption of shares of the fund. In addition, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the six months ended September 30, 2004, the amount of such expenses allocated
to the fund was $278,047.

The fund has entered into an arrangement with its custodian whereby credits
realized as a result of directed brokerage commissions, were used to reduce a
portion of the fund's expenses. During the six months ended September 30, 2004,
the funds custodian fees were reduced by $137 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$21,381 during the six months ended September 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the six months ended September 30, 2004, the amount of such
expenses was $57,442.

Note 3
For the six months ended September 30, 2004, purchases and sales of securities,
exclusive of short-term obligations, aggregated $607,745,049, and $576,514,625,
respectively.

Note 4
The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, the fund pays annual service
fees to the Distributor at a rate of 0.25% of average daily net assets for Class
A, Class B(1), Class B and Class C shares. In addition, the fund pays annual
distribution fees of 0.05% of average daily net assets for Class A shares and
0.75% of average daily net assets for Class B(1), Class B and Class C shares.
Currently, the annual service and distribution fees paid by Class B shares have
been voluntarily waived to 0.00%. The fund expects this waiver to continue,
although there is no guarantee that it will. The Distributor uses such payments
for personal services and/or the maintenance of shareholder accounts, to
reimburse securities dealers for distribution and marketing services, to furnish
ongoing assistance to investors and to defray a portion of its distribution and
marketing expenses. For the six months ended September 30, 2004, fees pursuant
to such plans amounted to $553,606, $679,300, and $240,986 for Class A, Class
B(1) and Class C shares, respectively. For Class A, Class B and Class C shares,
the payments are intended to reimburse the distributor for expenditures incurred
under the plan, and any unused payments are returnable to the fund. During the
six months ended September 30, 2004, the Distributor reimbursed a total of
$294,508 to Class B shares of the fund reflecting the estimated excess of
payments received over costs incurred under the plan. This amount is shown as
"Reimbursement of distribution fees" in the Statement of Operations. For Class
B(1), the payments compensate the distributor for services and expenditures
incurred under the plan, and none of the payments are returnable to the fund. As
of September 30, 2004, there were $3,625,865, $16,629 and $2,225,942 for Class
A, Class B, and Class C shares, respectively, of unreimbursed distribution and
shareholder servicing related expenses to be carried forward to future plan
years.

The fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of MetLife, earned initial sales charges aggregating
$1,416,764 and $5,829,512, respectively, on sales of Class A shares of the fund
during the six months ended September 30, 2004, and that MetLife Securities,
Inc. earned commissions aggregating $6,003,620 and $133,336 on sales of Class
B(1) and Class C shares, respectively, and the Distributor collected contingent
deferred sales charges aggregating $202,535, $424 and $6,810 on redemptions of
Class B(1), Class B and Class C shares, respectively, during the same period.

Note 5
MetLife announced that it has entered into an agreement to sell the Adviser as
part of a larger transaction to sell MetLife's asset management business to
BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset
management business is expected to occur in the first quarter of 2005. At the
time of the closing, the advisory agreement between the fund and the Adviser and
the distribution agreement between the fund and the Distributor will be
terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly
owned subsidiaries of BlackRock, will serve as investment adviser and
distributor, respectively.

A Special Meeting of Shareholders of the fund has been tentatively scheduled for
December 2004. At this meeting, shareholders of the fund will be asked to
consider and approve a plan of reorganization between the fund and the BlackRock
Balanced Portfolio. If the proposed reorganization is approved by shareholders
of the fund, the BlackRock Balanced Portfolio would acquire substantially all of
the assets and liabilities of the fund. In exchange, shareholders of the fund
would receive shares of the BlackRock Balanced Portfolio with an aggregate value
equivalent to the aggregate net asset value of their fund shares at the time of
the transaction. If the proposed reorganization is not approved by shareholders
of the fund, the Board of Trustees will need to consider other alternatives
relating to the management and operations of the fund, including without
limitations, seeking an alternative investment adviser for the fund or seeking
shareholder approval to liquidate the fund.*

   shares of any fund, nor is it a solicitation of any proxy.

(e)  During the periods ended March 31, 2004, and September 30, 2004, the
     Distributor reimbursed Class B shares of the fund the estimated excess of
     payments received over costs incurred under the 12B-1 plan. The effect of
     this reimbursement was to increase net investment income per share $0.07
     and $0.03, respectively, increase the total return 0.80% and 0.34%,
     respectively, and increase the ratio of net investment income to average
     net assets 0.80% and 0.65%, respectively.
(f)  Effective April 1, 2001, the fund has adopted the provisions on the AICPA
     Audit and Accounting Guide, Audit of Investment Companies and began
     amortizing premium on all fixed income securities. The effect of this
     change for the year ended March 31, 2002, was to decrease net investment
     income per share by $0.01, increase net realized and unrealized gain per
     share by $0.01, and decrease the ratio of net investment income in average
     and assets by 0.13%. The statement of changes and financial highlights for
     the period prior to April 1, 2001, have not been restated for this change

FROM THE CHAIRMAN
     State Street Research

The U.S. economy grew at a solid pace during the six-month period from April 1,
2004 to September 30, 2004. Gross Domestic Product (GDP), a common measure of
economic growth, rose at a pace of more than 3.5% for the first half of 2004.
Estimates for second half suggest that the pace of growth could have picked up
somewhat, as the US economy remains on solid ground.

Consumer confidence wavered early in the period as the number of new jobs added
to the economy fell below expectations. When the job picture brightened in April
and May, consumer confidence tracked higher. More than 1.2 million jobs were
added to the U.S. economy in the spring, and the quality of new jobs improved,
as reported by the U.S. Labor Department. However, caution returned on
disappointing jobs reports in July and August and consumer confidence pulled
back.

Yet, consumers continued to fuel the economy, pumping dollars into the retail
and housing markets. Sales of new and existing homes soared as homebuyers
anticipated higher mortgage rates ahead. Corporate profits continued to rise,
making it easier for companies to increase spending, especially on information
technology, electronic equipment and new jobs.

As the period wore on, it became clear that the days of record-low short-term
interest rates were coming to an end. In June, the Federal Reserve Board raised
the federal funds rate from 1.0% to 1.25%. The Fed raised this key short-term
rate to 1.5% in August and to 1.75% in September. These increases had little or
no impact on the financial markets because they had been widely anticipated and
because the Fed has signaled that it will take a measured approach to raising
rates as the economic recovery matures.

Stocks Stumble as Bonds Edge Higher

After a relatively positive start to the calendar year, a host of worries
stopped the major stock market indexes in their tracks. Investors grew more
cautious about interest rates, rising energy prices, the threat of terrorist
attacks and the outcome of the presidential election and stocks retreated. Value
stocks held up considerably better than growth stocks. The energy sector was the
stock market's strongest performer.

High-yield bonds continued to lead the bond market. Most other sectors of the
bond market eked out modest positive returns as the yield on the benchmark
10-year U.S. Treasury bond moved lower in the final months of the period. Yields
and bond prices move in opposite directions.

Looking Ahead

Any time the financial markets deliver negative returns, it is disheartening for
investors. However, the seeds of a new market rally are often sown in periods of
weakness and decline. With a diversified portfolio and a long-term perspective
on the markets, it is easier to weather periods of volatility--and more likely
that you may reap the potential benefits in better times. We urge you to talk to
your investment professional about your investment plan. And we look forward to
helping you achieve your long-term financial goals.

Sincerely,

/s/ Richard S. Davis

PERFORMANCE
   Discussion as of September 30, 2004

How State Street Research High Income Fund Performed

State Street Research High Income Fund (Class A shares, without sales charge)
returned 3.53% for the six-month period ended September 30, 2004. That was
higher than its peer group, the Lipper High Current Yield Funds Average, which
was 3.43% for the period. However, the fund underperformed the CSFB Global High
Yield II Index, which returned 4.29% over the same period.

Keep in mind that the performance data quoted represents past performance and is
no guarantee of future results. Current performance may be lower or higher than
the performance data quoted herein. For the most recent month-end performance
results, visit our website at www.ssrfunds.com. The fund's share price, yield
and return will fluctuate, and you may have a gain or loss when you sell your
shares. All returns assume reinvestment of capital gains distributions and
income dividends at net asset value. The returns shown do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares.

Average annual total return without sales charge does not reflect the maximum
applicable sales charges. If the applicable sales charges were deducted,
performance results would be lower.

Average annual total return at maximum applicable sales charge reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B(1) or B share
or 1% Class C share contingent deferred sales charge (CDSC) where applicable.

Performance for Class B(1) shares reflects Class B share performance through
December 31, 1998, and Class B(1) performance thereafter. If the returns for
Class B(1) shares had reflected their current service/ distribution (Rule 12b-1)
fees for the entire period, these returns would have been lower.

Class S shares, offered without sales charge, are available through certain
employee benefit plans and special programs.

The Lipper High Current Yield Funds Average shows the performance of a category
of mutual funds with similar goals. The Lipper average shows you how well the
fund has done compared to competing funds.

The CSFB Global High Yield II Index mirrors the public high-yield debt market,
representing a total of 250 different sectors within this market. The index is
unmanaged and does not take transaction charges into consideration. It is not
possible to invest directly in an index.


Reasons for the Fund's Performance

Early in the period, the high-yield sector underperformed Treasuries as mixed
economic news and increased geopolitical risk pressured the sector. However,
high-yield performance picked up in the second half of the period as the economy
put a "soft patch" behind it. High-yield led the fixed income markets for the
six-month reporting period.

The fund lost out on some performance because it had lower exposure to the
lowest-quality CCC-rated issues than its benchmark. CCC-rated issues
outperformed higher-rated, more stable issues during the period. However, this
disappointment was somewhat offset by strong performance from B-rated
securities, where the fund's exposure was higher than that of its benchmark.

An emphasis on securities in the chemical industry helped the fund's return
because chemical bonds were strong performers. Our decision to underweight the
utilities sector was also rewarded as the sector lagged during the period.

Looking Ahead

We continue to believe that the high-yield sector has the potential to generate
competitive returns relative to other fixed income alternatives. However, after
more than a year of strong price appreciation, the high-yield bond sector
appears to be at or near full value. In this environment, we believe that
security selection and risk avoidance will be key factors in performance.

A Word about Risk

The major risks of investing in high-yield, high-risk debt securities-- often
referred to as "junk bonds"--include the tendency for prices to fall when the
economy is sluggish or overall corporate earnings are weak. High-yield,
high-risk debt securities reflect a greater possibility that adverse changes in
an issuer's business or financial condition, or in general economic conditions,
may impair the issuer's ability to pay principal and interest on the securities.
The value of any bonds held by the fund is likely to decline when interest rates
rise; this risk is greater for bonds with longer maturities.

Because of active management, there is no guarantee that the fund invests, or

About Your Fund Expenses

As a fund shareholder, you incur two types of costs: (1) Transaction costs,
which include sales charges, and (2) ongoing expenses, which include management
fees, service/distribution fees (12b-l) and "other" expenses. The examples below
illustrate the ongoing cost in dollars of investing in the fund and allow you to
compare these costs with the expenses of other funds. The examples are based on
a $1,000 investment at the beginning of the period and held for the entire
period from March 31, 2004 to September 30, 2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number shown for your
fund under the column "Expenses Paid during the Period".

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending balance and expenses paid during the period. To
compare your fund's ongoing expenses with those of other funds, simply compare
this 5% hypothetical example with the 5% hypothetical examples shown in the
shareholder reports of other funds.

*  Expenses are equal to the fund's annualized expense ratio multiplied by the
   average account value over the period, multiplied by the number of days in
   the period and then divided by the number of days in the year.


Please note that the expenses shown in the table are meant to highlight and help
you compare ongoing costs only and do not reflect transactional expenses such as
sales charges, which would result in higher total expenses. It should also be
noted that, for certain funds, expenses have been subsidized or reduced through
expense offset arrangements, which reduces costs for shareholders. Generally,
the fund expects that the expense subsidy or expense offset arrangement will
continue although there is no guarantee that it will. Please see the fund's
prospectus for more information.

Notes to Unaudited Financial Statements
- --------------------------------------------------------------------------------
September 30, 2004


Note 1

State Street Research High Income Fund is a series of State Street Research
Income Trust (the "Trust"), which is organized as a Massachusetts business trust
and is registered under the Investment Company Act of 1940, as amended as an
open-end management investment company. The Trust consists presently of two
separate funds: State Street Research High Income Fund and State Street Research
Asset Allocation Fund.

The investment objective of the fund is to seek, primarily, high current income
and, secondarily, capital appreciation, from investments in fixed income
securities. Under normal circumstances, the fund invests at least 80% of its net
assets in lower-quality securities, primarily "junk bonds". At the time of
purchase, these securities are rated within or below the BB or Ba major rating
categories (Standard & Poor's/Moody's), or are unrated but considered equivalent
by the investment manager. The fund may not invest more than 20% of its total
assets in securities rated in the CCC/Caa or lower rating categories or
equivalent at the time of purchase. Fixed income securities include bonds and
other debt-like instruments such as asset- or mortgage-backed securities, and
preferred stocks.

The fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 4.50% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) shares pay annual service and
distribution fees equal to 1.00% of average daily net assets and automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) shares are subject to a contingent deferred sales charge
on certain redemptions made within six years of purchase. Class B shares are
offered only to current shareholders through reinvestment of dividends and
distributions or through exchanges from existing Class B accounts of State
Street Research funds . Currently, the annual service and distribution fees paid
by Class B shares have been voluntarily reduced to 0.00%. Class B shares
automatically convert into Class A shares at the end of eight years. Class B
shares are subject to a contingent deferred sales charge on certain redemptions
made within five years of purchase. Class C shares are subject to a contingent
deferred sales charge of 1.00% on any shares redeemed within one year of
purchase. Class C shares also pay annual service and distribution fees equal to
1.00% of average daily net assets. Class S shares are only offered through
certain retirement accounts, advisory accounts of State Street Research &
Management Company (the "Adviser"), an investment management subsidiary of
MetLife, Inc. ("MetLife"), and special programs. No sales charge is imposed at
the time of purchase or redemption of Class S shares. Class S shares do not pay
any service or distribution fees. The fund's expenses are borne pro rata by each
class, except that each class bears expenses, and has exclusive voting rights
with respect to provisions of the plans of distribution, related specifically to
that class. Income, expenses (other than service and distribution fees), and
realized and unrealized gains or losses on investments are allocated to each
class of shares based on its relative net assets. The Trustees declare separate
dividends on each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.


A. Investment Valuation

Values for listed equity securities reflect final sales on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("Nasdaq") system are valued at closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Fixed income securities are valued by a pricing service, which
utilizes market transactions, quotations from dealers, and various relationships
among securities in determining value. If not valued by a pricing service, such
securities are valued at prices obtained from independent brokers. Short-term
securities maturing within sixty days are valued at amortized cost. Other
securities, if any, are valued at their fair value as determined in good faith
under consistently applied procedures established by and under the supervision
of the Trustees. In the event that the market quotations for a portfolio
instrument are not deemed to be readily available, the Investment Adviser's
Valuation Committee determines the fair


10 The notes are an integral part of the financial statements.



value for such portfolio instrument. The fair value of any such portfolio
instruments are determined based upon a consideration of all available facts and
information. The fair valuation of a restricted portfolio instrument reflects
the inherent worth of the portfolio instrument, without regard to the
restrictive feature, adjusted for any diminution in value resulting from the
restrictive feature. The Investment Adviser and the Custodian also monitor
domestic and foreign markets and news information for any developing events that
may have an impact on the valuation of portfolio instruments. Such monitoring
includes general market news and financial market information sources currently
utilized in making investment decisions, trading and investment personnel
located abroad, foreign regional brokers, and/or foreign custodians. The value
assigned to these securities is based upon available information at the time,
and does not necessarily represent the amount which might ultimately be realized
upon sale.

B. Security Transactions

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered. As part of the custodian contract
between the custodian bank and the fund, the custodian bank has a lien on the
securities of the fund to the extent permitted by the fund's investment
restriction to cover any advances made by the custodian bank for the settlement
of securities purchased by the fund. At September 30, 2004, the payable to the
custodian bank of $228,163 represents the amount due for cash advance for the
settlement of a security purchased.

C. Net Investment Income

Net investment income is determined daily and consists of interest and dividends
accrued and discount earned, less the estimated daily expenses of the fund.
Interest income is accrued daily as earned. Dividend income is accrued on the
ex-dividend date. The fund is charged for expenses directly attributable to it,
while indirect expenses are allocated between both funds in the Trust.

D. Dividends

Dividends from net investment income are declared daily and paid or reinvested
monthly. Net realized capital gains, if any, are distributed annually, unless
additional distributions are required for compliance with applicable tax
regulations.

Income dividends and capital gains distributions are determined in accordance
with federal income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
caused by differing treatment of accrued interest on defaulted bonds and premium
amortization on fixed income securities.

E. Federal Income Taxes

No provision for federal income taxes is necessary because the fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods.

At March 31, 2004, the fund had a net capital loss carryforward of $455,595,025
available, to the extent provided in regulations, to offset future capital
gains, if any, of which $3,347,001, $43,790,700, $69,423,365, $274,585,781 and
$64,448,178 expire on March 31, 2007, 2008, 2009, 2010 and 2011, respectively. A
portion of the losses expiring in 2007, 2008, 2009 and 2010, $3,347,001,
$5,252,309, $11,304,243 and $949,368, respectively, were acquired in connection
with the merger of State Street Research Strategic Income Fund. Future
utilization of these losses may be limited under current tax laws.

F. Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of income and expenses during
the reporting period. Actual results could differ from these estimates.

G. Securities Lending

The fund may seek additional income by lending portfolio securities to qualified
institutions. The fund will receive cash or securities as collateral in an
amount equal to at least 100% of the current market value of any loaned
securities plus accrued interest. By reinvesting any cash collateral it receives
in these transactions, the fund could realize additional gains and losses. If
the borrower fails to return the securities and the value of the collateral has
declined during the term of the loan, the fund will bear the loss. At September
30, 2004, the value of the securities loaned and the value of collateral were
$33,960,405 and $34,638,408, respectively. During the six months ended September
30, 2004, income from securities lending amounted to $36,010 .

H. Futures

The fund may enter into futures contracts as a hedge against unfavorable market
conditions and to enhance income. The fund will not purchase any futures
contract if, after such purchase, more than one-third of net assets would be
represented by long future contracts. The fund will limit its risks by entering
into a futures position only if it appears to be a liquid investment.

Upon entering into a futures contract, the fund deposits with the selling broker
sufficient cash or U.S. government securities to meet the minimum "initial
margin" requirements. Thereafter, the fund receives from or pays to the broker
cash or U.S. government securities equal to the daily fluctuation in value of
the contract ("variation margin"), which is recorded as unrealized gain or loss.
When the contract is closed, the fund records a realized gain or loss equal to
the difference between the value of the contract at the time it has opened and
the value at the time it was closed.

The potential risk to the fund is that the change in value of futures contracts
may not correspond to the change in value of the hedged instruments. In
addition, losses may arise in changes from the value of the underlying
instruments, if there is an illiquid secondary market for the contracts, or if
the counterparty to the contract is unable to perform.

Note 2

The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.60% of the first $500 million of net
assets annually, 0.55% of the next $500 million, and 0.50% of any amount over $1
billion. In consideration of these fees, the Adviser furnishes the fund with
management, investment advisory, statistical and research facilities and
services. The Adviser also pays all salaries, rent and certain other expenses of
management. During the six months ended September 30, 2004, the fees pursuant to
such agreement amounted to $950,244.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), provides certain shareholder services to the fund such as
responding to inquiries and instructions from investors with respect to the
purchase and redemption of shares of the fund. In addition, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the six months ended September 30, 2004, the amount of such expenses allocated
to the fund was $135,981.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$15,165 during the six months ended September 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among State Street Research funds.
During the six months ended September 30, 2004, the amount of such expenses was
$46,299.

Note 3

For the six months ended September 30, 2004, purchases and sales of securities,
exclusive of short-term obligations and U.S. government obligations, aggregated
$197,785,095 and $226,326,596, respectively.

Note 4

The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, the fund pays annual service
fees to the Distributor at a rate of 0.25% of average daily net assets for Class
A, Class B(1) and Class C shares. In addition, the fund pays annual distribution
fees of 0.05% of average daily net assets for Class A shares. The fund pays
annual distribution fees of 0.75% of average daily net assets for Class B(1) and
Class C shares. Currently, the annual service and distribution fees paid by
Class B shares have been voluntarily reduced to 0.00%. The fund expects this
waiver to continue, although there is no guarantee that it will. The Distributor
uses such payments for personal services


                                       State Street Research High Income Fund 11



and/or the maintenance of shareholder accounts, to reimburse securities dealers
for distribution and marketing services, to furnish ongoing assistance to
investors and to defray a portion of its distribution and marketing expenses.
For the six months ended September 30, 2004, fees pursuant to such plans
amounted to $330,428, $192,773 and $54,889 for Class A, Class B(1) and Class C
shares, respectively. For Class A, Class B and Class C shares, the payments are
intended to reimburse the distributor for expenditures incurred under the plan,
and any unused payments are returnable to the fund. During the six months ended
September 30, 2004, the Distributor reimbursed a total of $271,424 to Class B
shares of the fund reflecting the estimated excess of payments received over
costs incurred under the plan. This amount is shown as "Reimbursement of
distribution fees" in the Statement of Operations. As of September 30, 2004,
there were $3,102,114, $12,867 and $2,440,763 for Class A, Class B(1) and Class
C, respectively, of unreimbursed distribution and shareholder servicing related
expenses to be carried forward to future plan years. For Class B(1) shares, the
payments compensate the distributor for services and expenditures incurred under
the plan, and none of the payments are returnable to the fund.

The fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of MetLife, earned initial sales charges aggregating
$270,005 and $1,653,913, respectively, on sales of Class A shares of the fund
during the period ended September 30, 2004, and that MetLife Securities, Inc.,
earned commissions aggregating $922,534 and $69,488 on sales of Class B(1) and
Class C shares, respectively, and the Distributor collected contingent deferred
sales charges aggregating $75,332, $166 and $2,628 on redemptions of Class B(1),
Class B and Class C shares, respectively, during the same period.

Note 5

MetLife announced that it has entered into an agreement to sell the Adviser as
part of a larger transaction to sell MetLife's asset management business to
BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset
management business is expected to occur in the first quarter of 2005. At the
time of the closing, the advisory agreement between the fund and the Adviser and
the distribution agreement between the fund and the Distributor will be
terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly
owned subsidiaries of BlackRock, will serve as investment adviser and
distributor, respectively.

A Special Meeting of Shareholders of the fund has been tentatively scheduled for
December 2004. At this meeting, shareholders of the fund will be asked to
consider and approve a plan of reorganization between the fund and the BlackRock
High Yield Bond Portfolio. If the proposed reorganization is approved by
shareholders of the fund, the BlackRock High Yield Bond Portfolio would acquire
substantially all of the assets and liabilities of the fund. In exchange,
shareholders of the fund would receive shares of the BlackRock High Yield Bond
Portfolio with an aggregate value equivalent to the aggregate net asset value of
their fund shares at the time of the transaction. If the proposed reorganization
is not approved by shareholders of the fund, the Board of Trustees will need to
consider other alternatives relating to the management and operations of the
fund, including without limitations, seeking an alternative investment adviser
for the fund or seeking shareholder approval to liquidate the fund.*

*The foregoing is not an offer to sell, nor a solicitation of an offer to buy,
shares of any fund, nor is it a solicitation of any proxy.

(e) Effective April 1, 2001, the fund has adopted the provisions of the AICPA
    Audit and Accounting Guide, Audit of Investment Companies and began
    amortizing premium on all fixed income securities. The effect of this change
    for the year ended March 31, 2002, was to decrease net investment income per
    share by $0.05, increase net realized and unrealized loss per share by
    $0.05, and decrease the ratio of net investment income to average net assets
    by 1.47%. The financial highlights for the period prior to April 1, 2001,
    have not been restated for this change in policy.
(f) Audited by other auditors
(g) During the year ended March 31, 2004, the Distributor made restitution
    payments to the fund as part of a settlement with NASD. These payments had
    no effect on net investment income per share, total return and the ratio of
    net investment income to average net assets.
(h) During the periods ended March 31, 2004, and September 30, 2004, the
    Distributor reimbursed Class B shares of the fund the estimated excess of
    payments received over costs incurred under the 12b-1 plan. The effect of
    this reimbursement was to increase net investment income per share $0.00 and
    $0.02, respectively, increase the total return 0.00% and 0.57%, respectively
    and increase the ratio of net investment income to average net assets 0.12%
    and 1.30%, respectively.
