FROM THE CHAIRMAN


[photo of Ralph F. Verni]


Dear Shareholder:
In 1998, financial markets in the United States and most developed foreign
nations delivered strong gains. The U.S. economy boosted personal income and
kept unemployment low. Yet growth was moderate enough to hold inflation down to
a mere 1.5% for the year. During the summer, the collapse of Russia's currency
sent waves through the world's markets, but a fast-acting Federal Reserve Board
helped stem a crisis. Currencies continued to slump in many emerging markets. In
some, devaluation threatened, with Brazil in the hot seat at year-end.


Stocks

A steep U.S. stock market correction late in the summer was short-lived. Despite
signs of slower profit growth, the market staged a comeback in the fourth
quarter. Technology stocks and large company growth stocks were the strongest
performers, led by Internet stocks which delivered surprising gains. The S&P 500
was up by more than 20% for an unprecedented fourth consecutive year.(1)
However, gains were concentrated in a narrow band of stocks. The average stock
on the New York Stock Exchange actually lost ground for the year. And the stocks
of small and medium-sized companies continued to lag despite a fourth-quarter
comeback.


Bonds

Bonds benefited from the Federal Reserve Board's three quick interest rate cuts
in autumn. The yield on the bellwether 30-year U.S. Treasury bond fell below
5.0%, then rose slightly at year-end. Not surprisingly, U.S. Treasury bonds led
fixed income market performance for the year. Most other segments of the bond
market delivered attractive single-digit gains. High-yield bonds disappointed
investors, gaining only 0.6% as measured by the First Boston High Yield Index.


International

Foreign markets delivered mixed returns in 1998. In Europe, expectations for the
new common currency, the euro, ran high. Although this helped European markets,
they did better in the first half of the year than in the second. Most emerging
markets were hurt by currencies that continued to slump against the dollar, or
by fears of devaluation, which materialized in Russia, then threatened in
Brazil. Japan showed some willingness to address its lingering economic
problems. But the modest gains attributed to Japanese stocks owned by U.S.
investors were primarily the result of a weaker dollar.


Outlook and Opportunities

As investors, you may be asking where the opportunities are in a stock market
that has soared for the better part of a decade and a bond market where interest
rates are at or near historic lows. My reply: in diversification -- and in
markets that have been beaten down, such as small and mid-cap stocks, high-yield
bonds, and foreign markets. But every investor has individual goals. Now is a
good time to consult your financial professional. And as always, thank you for
your confidence in State Street Research funds.


Sincerely,

/s/ Ralph F. Verni

PORTFOLIO MANAGER'S REVIEW
Tax-Exempt Fund: Another solid year for municipal bonds

[photo of Paul J. Clifford, Jr.]

Paul J. Clifford, Jr.
Portfolio Manager

We spoke with Paul Clifford, portfolio manager of State Street Research
Tax-Exempt Fund, about the Fund's performance for the year ended December 31,
1998 and his views on the period ahead.


Q: How did the Fund perform last year?

A: It was a good year for the Fund relative to its peer group. Class A shares
returned 5.79% for the 12 months ended December 31, 1998 [does not reflect sales
charge].(2) That was higher than the Lipper average general municipal debt fund,
which returned 5.32%. The Fund underperformed the Lehman Brothers Municipal Bond
Index, which gained 6.48% for the same period.


Q: Why did the Fund outperform its peer municipal bond funds?

A: We made three key decisions that worked in the Fund's favor. First, we
lengthened the duration of the Fund based on the outlook of State Street
Research fixed income group. Duration is a measure of the Fund's sensitivity to
changes in interest rates. What's more, the timing of our decision to lengthen
duration was fortuitous: we lengthened ahead of the decline in interest rates.

Second, we made a decision early in the year to increase the credit quality of
the portfolio. The yield premium for lesser-quality bonds had declined
substantially, making valuations less compelling. Third, we focused on the
structure of our bonds, examining each opportunity for the optimal combination
of maturity, price, and call features.


Q: What changes did you make to the composition of the portfolio during the
year?

A: We added investments in education, and we increased our exposure to insured
bonds. That's not surprising in light of our emphasis on quality. It also
reflects a trend in our market: In the past five years, the percentage of bonds
that are insured with AAA ratings has grown from 34% to 55%. Insurance premiums
have come down, and yields have become increasingly competitive.

We also reduced our exposure to health care bonds and turned cautious on utility
bonds, where an evolving regulatory environment has induced uncertainty.
Overall, however, we kept the turnover of the Fund quite low for the year.


Q: What is your outlook for municipal bonds in the period ahead?

A: We believe that slowing global economic growth could continue to affect the
U.S. economy. As a result, we believe that interest rates could come down even
further. Right now the municipal market is inexpensive compared to the U.S.
Treasury market.

NOTES TO FINANCIAL STATEMENTS

December 31, 1998


Note 1

State Street Research Tax-Exempt Fund (the "Fund"), is a series of State Street
Research Tax-Exempt Trust (the "Trust"), which was organized as a Massachusetts
business trust in December, 1985 and is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The Fund
commenced operations in August, 1986. The Trust consists presently of two
separate funds: State Street Research Tax-Exempt Fund and State Street Research
New York Tax-Free Fund.

The investment objective of the Fund is to seek a high level of interest income
exempt from federal income taxes. In seeking to achieve its investment
objective, the Fund invests primarily in tax-exempt debt obligations which the
investment manager believes will not involve undue risk.

The Fund offers four classes of shares. Class A shares are subject to an initial
sales charge of up to 4.50% and pay a service fee equal to 0.25% of average
daily net assets. Class B shares are subject to a contingent deferred sales
charge on certain redemptions made within five years of purchase and pay annual
distribution and service fees of 1.00%. Class B shares automatically convert
into Class A shares (which pay lower ongoing expenses) at the end of eight years
after the issuance of the Class B shares. Effective January 1, 1999, the Fund
began offering Class B(1) shares which are subject to a contingent deferred
sales charges on certain redemptions made within six years. Class C shares are
subject to a contingent deferred sales charge of 1.00% on any shares redeemed
within one year of their purchase. Class C shares also pay annual distribution
and service 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 indirect wholly owned subsidiary of Metropolitan
Life Insurance Company ("Metropolitan"), 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 distribution or service 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 Plan of Distribution,
related specifically to that class. 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 generally accepted accounting principles for investment companies.


A. Investment Valuation

Tax-exempt securities are valued by a pricing service, which utilizes market
transactions, quotations from dealers, and various relationships among
securities in determining value. Short-term obligations are valued at amortized
cost. Other securities, if any, are valued at their fair value as determined in
accordance with established methods consistently applied.


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.


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

STATE STREET RESEARCH TAX-EXEMPT FUND
- --------------------------------------------------------------------------------
NOTES (cont'd)
- --------------------------------------------------------------------------------


C. Net Investment Income

Net investment income is determined daily and consists of interest accrued and
discount earned, less amortization of premium and the estimated daily expenses
of the Fund. Interest income is accrued daily as earned. The Fund is charged for
expenses directly attributable to it, while indirect expenses are allocated
between both funds in the Trust.


D. Dividends

Dividends are declared daily by the Fund based upon projected net investment
income 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. For the year ended December 31,
1998, the Fund has designated as long-term $1,173,629 of the distributions from
net realized gains.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.


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.


F. Futures Contracts

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 futures 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 was opened and
the value at the time it was closed.


G. Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles 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 those 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. 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. During the year ended December 31, 1998, there were no
loaned securities.


Note 2

The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.55% of the Fund's average daily net
assets. 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 year ended December 31, 1998, the fees pursuant to such
agreement amounted to $1,527,580.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), an indirect wholly owned subsidiary of Metropolitan, 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. During the year ended December 31, 1998, the amount of such
expenses was $115,280.

The Fund has entered into an arrangement with its transfer agent whereby credits
realized as a result of invested cash balances were used to reduce a portion of
the Fund's expense. During the year ended December 31, 1998 the Fund's transfer
agent fees were reduced by $36,420 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$36,639 during the year ended December 31, 1998.


Note 3

For the year ended December 31, 1998, purchases and sales of securities,
exclusive of short-term obligations, aggregated $108,615,904 and $103,250,685,
respectively.


Note 4

The Trust has adopted a Plan of Distribution Pursuant to Rule 12b-1 (the "Plan")
under the Investment Company Act of 1940, as amended. Under the Plan, 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 and Class C shares. In addition, the Fund pays
annual distribution fees of 0.75% of average daily net assets for Class B and
Class C shares. The Distributor uses such payments for personal services and/or
the maintenance or servicing 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 year ended December 31, 1998, fees pursuant to such plan amounted to
$515,943, $579,441 and $31,024 for Class A, Class B and Class C shares,
respectively.

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $68,263 and $428,743, respectively, on sales of Class A shares of
the Fund during the year ended December 31, 1998, and that MetLife Securities,
Inc. earned commissions aggregating $392,902 on sales of Class B shares, and the
Distributor collected contingent deferred sales charges aggregating $89,197 and
$1,045 on redemptions of Class B and Class C shares, respectively, during the
same period.

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, 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 State Street Research Tax-Exempt
Fund (a series of State Street Research Tax-Exempt Trust, hereafter referred to
as the "Trust") at December 31, 1998, and the results of its operations, the
changes in its net assets and the financial highlights for 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 Trust'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
December 31, 1998 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

STATE STREET RESEARCH TAX-EXEMPT FUND
- --------------------------------------------------------------------------------
MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

State Street Research Tax-Exempt Fund had a strong year. Class A shares returned
5.79% [does not reflect sales charge] for the 12 months ended December 31, 1998.
This total return performance was higher than that of the average general
municipal debt fund tracked by Lipper Analytical Services, which returned 5.32%
for the same period. The Lehman Brothers Municipal Bond Index gained 6.48% for
the same period.

The Fund currently invests in tax-exempt debt obligations with an emphasis on
research to maximize return and manage risk.

The manager added value by lengthening the Fund's duration, raising the Fund's
overall quality, and focusing on the structure of each bond added to the
portfolio. Turnover was low, and few major changes were made to the portfolio
for the year.

December 31, 1998


Keep in mind that past performance is no guarantee of future results. 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 gain
distributions and income dividends at net asset value. Performance reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B share or 1%
Class C share contingent deferred sales charge, where applicable. The fund's
returns include performance before the creation of share classes. If this
performance reflected the share classes' current 12b-1 fees, the fund's returns
may have been lower. Class S shares, offered without a sales charge, are
available only through certain employee benefit plans and special programs. The
Lehman Brothers Municipal Bond Index is comprised of 8,000 fixed-rate
investment-grade municipal bonds, all from issues larger than $50 million and
with maturities greater than two years. The index is unmanaged and does not take
sales charges into consideration. Direct investment in the index is not
possible; results are for illustrative purposes only.

                     Lehman Municipal Bond Index Compared To
                       Change In Value Of $10,000 Invested

FROM THE CHAIRMAN


[photo of Ralph F. Verni]


Dear Shareholder:

In 1998, financial markets in the United States and most developed foreign
nations delivered strong gains. The U.S. economy boosted personal income and
kept unemployment low. Yet growth was moderate enough to hold inflation down to
a mere 1.5% for the year. During the summer, the collapse of Russia's currency
sent waves through the world's markets, but a fast-acting Federal Reserve Board
helped stem a crisis. Currencies continued to slump in many emerging markets. In
some, devaluation threatened, with Brazil in the hot seat at year-end.


Stocks

A steep U.S. stock market correction late in the summer was short-lived. Despite
signs of slower profit growth, the market staged a comeback in the fourth
quarter. Technology stocks and large company growth stocks were the strongest
performers, led by Internet stocks which delivered surprising gains. The S&P 500
was up by more than 20% for an unprecedented fourth consecutive year.(1)
However, gains were concentrated in a narrow band of stocks. The average stock
on the New York Stock Exchange actually lost ground for the year. And the stocks
of small and medium-sized companies continued to lag despite a fourth-quarter
comeback.


Bonds

Bonds benefited from the Federal Reserve Board's three quick interest rate cuts
in autumn. The yield on the bellwether 30-year U.S. Treasury bond fell below
5.0%, then rose slightly at year-end. Not surprisingly, U.S. Treasury bonds led
fixed income market performance for the year. Most other segments of the bond
market delivered attractive single-digit gains. High-yield bonds disappointed
investors, gaining only 0.6% as measured by the First Boston High Yield Index.


International

Foreign markets delivered mixed returns in 1998. In Europe, expectations for the
new common currency, the euro, ran high. Although this helped European markets,
they did better in the first half of the year than in the second. Most emerging
markets were hurt by currencies that continued to slump against the dollar, or
by fears of devaluation, which materialized in Russia, then threatened in
Brazil. Japan showed some willingness to address its lingering economic
problems. But the modest gains attributed to Japanese stocks owned by U.S.
investors were primarily the result of a weaker dollar.


Outlook and Opportunities

As investors, you may be asking where the opportunities are in a stock market
that has soared for the better part of a decade and a bond market where interest
rates are at or near historic lows. My reply: in diversification -- and in
markets that have been beaten down, such as small and mid-cap stocks, high-yield
bonds, and foreign markets. But every investor has individual goals. Now is a
good time to consult your financial professional. And as always, thank you for
your confidence in State Street Research funds.

Sincerely,

/s/ Ralph F. Verni

Ralph F. Verni
Chairman

(1)The S&P 500 (officially the "Standard and Poor's 500 Composite Stock Price
Index") is an unmanaged index of 500 U.S. stocks. The index does not take
transaction charges into consideration. It is not possible to invest directly in
the index.

(2)5.14% for Class B shares; 5.01% for Class C shares; 6.18% for Class S shares.

(3)Keep in mind that past performance is no guarantee of future results. 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 gain
distributions and income dividends at net asset value. Performance reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B share or 1%
Class C share contingent deferred sales charge, where applicable.

(4)Class S shares, offered without a sales charge, are available through certain
employee bene-fit plans and special programs.

(5)The fund's returns include performance before the creation of share classes.
If this performance reflected the share classes' current 12b-1 fees, the fund's
returns may have been lower.


Please note that the discussion throughout this shareholder report is dated as
indicated and, because of possible changes in viewpoint, data and transactions,
should not be relied upon as being current thereafter.

PORTFOLIO MANAGER'S REVIEW
New York Tax-Free Fund: Another solid year for municipal bonds


[photo of Paul Clifford]

Paul Clifford
Portfolio Manager


We spoke with Paul Clifford, portfolio manager of State Street Research New York
Tax-Free Fund, about the Fund's performance for the year ended December 31, 1998
and his views on the period ahead.


Q: How did the Fund perform last year?

A: It was a good year for the Fund. Class A shares returned 5.92% for the 12
months ended December 31, 1998 [does not reflect sales charge].(2) That was
higher than the Lipper average New York municipal debt fund, which returned
5.64%. The Fund underperformed the Lehman Brothers Municipal Bond Index, which
gained 6.48% for the same period.


Q: Why did the Fund outperform other New York municipal bond funds?

A: We made three key decisions that worked in the Fund's favor. First, we
lengthened the duration of the Fund based on the outlook of State Street
Research fixed income group. Duration is a measure of the Fund's sensitivity to
changes in interest rates. What's more, the timing of our decision to lengthen
duration was fortuitous: we lengthened ahead of the decline in interest rates.

Second, we made a decision early in the year to increase the credit quality of
the portfolio. The yield premium for lesser-quality bonds had declined
substantially, making valuations less compelling. Third, we focused on the
structure of our bonds, examining each opportunity for the optimal combination
of maturity, price, and call features.


Q: What changes did you make to the composition of the portfolio during the
year?

A: We added investments in education, and we increased our exposure to insured
bonds. That's not surprising in light of our emphasis on quality. It also
reflects a trend in our market: In the past five years, the percentage of bonds
that are insured with AAA ratings has grown from 34% to 55%. Insurance premiums
have come down, and yields have become increasingly competitive.

We also reduced our exposure to health care bonds and turned cautious on utility
bonds, where an evolving regulatory environment has induced uncertainty.
Overall, however, we kept the turnover of the Fund quite low for the year.


Q: What is your outlook for New York bonds in the period ahead?

A: We believe that slowing global economic growth could continue to affect the
U.S. economy and that eventually it will be felt in New York state as well. As a
result, we believe that interest rates could come down even further. Right now
the municipal market is inexpensive compared to the U.S. Treasury market.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
December 31, 1998


Note 1

State Street Research New York Tax-Free Fund (the "Fund"), is a series of State
Street Research Tax-Exempt Trust (the "Trust"), which was organized as a
Massachusetts business trust in December, 1985 and is registered under the
Investment Company Act of 1940, as amended, as an open-end management
investment company. The Fund commenced operations in July, 1989. The Trust
consists presently of two separate funds: State Street Research New York
Tax-Free Fund and State Street Research Tax-Exempt Fund.

The investment objective of the Fund is to seek a high level of interest income
exempt from federal income taxes and New York State and New York City personal
income taxes. To achieve its investment objective, the Fund intends to invest
primarily in securities which are issued by or on behalf of New York State or
its political subdivisions and by other governmental entities.

The Fund offers four classes of shares. Class A shares are subject to an
initial sales charge of up to 4.50% and pay a service fee equal to 0.25% of
average daily net assets. Class B shares are subject to a contingent deferred
sales charge on certain redemptions made within five years of purchase and pay
annual distribution and service fees of 1.00%. Class B shares automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years after the issuance of the Class B shares. Effective January 1,
1999, the Fund began offering Class B(1) shares which are subject to a
contingent deferred sales charge on certain redemptions made within six years.
Class C shares are subject to a contingent deferred sales charge of 1.00% on
any shares redeemed within one year of their purchase. Class C shares also pay
annual distribution and service 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 indirect wholly owned subsidiary of
Metropolitan Life Insurance Company ("Metropolitan"), 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 distribution or service 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
Plan of Distribution, related specifically to that class. 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 generally accepted accounting principles for investment companies.


A. Investment Valuation

Tax-exempt securities are valued by a pricing service, which utilizes market
transactions, quotations from dealers, and various relationships among
securities in determining value. Short-term obligations are valued at amortized
cost. Other securities, if any, are valued at their fair value as determined in
accordance with established methods consistently applied.


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

NOTES (cont'd)
- --------------------------------------------------------------------------------


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.


C. Net Investment Income

Net investment income is determined daily and consists of interest accrued and
discount earned, less amortization of premium and the estimated daily expenses
of the Fund. Interest income is accrued daily as earned. The Fund is charged
for expenses directly attributable to it, while indirect expenses are allocated
between both funds in the Trust.


D. Dividends

Dividends are declared daily by the Fund based upon projected net investment
income 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. For the year ended December 31,
1998, the Fund has designated as long-term $349,984 of the distributions from
net realized gains.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.


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.


F. Futures Contracts

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 futures 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 realized gain or
loss equal to the differences between the value of the contract at the time it
was opened and the value at the time it was closed.


G. Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles 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 those 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. 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. During the year ended December 31, 1998,
there were no loaned securities.


Note 2

The Trust and the Adviser have entered into an agreement under which the
Adviser earns monthly fees at an annual rate of 0.55% of the Fund's average
daily net assets. 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 year ended December 31, 1998, the fees
pursuant to such agreement amounted to $386,106.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), an indirect wholly owned subsidiary of Metropolitan, 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. During the year ended December 31, 1998, the amount of such
expenses was $34,940.

The Fund has entered into an arrangement with its transfer agent whereby
credits realized as a result of uninvested cash balances were used to reduce a
portion of the Fund's expense. During the year ended December 31, 1998 the
Fund's transfer agent fees were reduced by $12,467 under this agreement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$18,667 during the year ended December 31, 1998.


Note 3

The Distributor and its affiliates may from time to time and in varying amounts
voluntarily assume some portion of fees or expenses relating to the Fund.
During the year ended December 31, 1998, the amount of such expenses assumed by
the Distributor and its affiliates was $94,339.


Note 4

For the year ended December 31, 1998, purchases and sales of securities,
exclusive of short-term obligations, aggregated $24,984,042 and $23,141,209,
respectively.


Note 5

The Trust has adopted a Plan of Distribution Pursuant to Rule 12b-1 (the
"Plan") under the Investment Company Act of 1940, as amended. Under the Plan,
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 and Class C shares. In addition,
the Fund pays annual distribution fees of 0.75% of average daily net assets for
Class B and Class C shares. The Distributor uses such payments for personal
services and/or the maintenance or servicing 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 year ended December 31, 1998, fees
pursuant to such plan amounted to $52,247, $181,161 and $9,175 for Class A,
Class B and Class C shares, respectively.

Note 5 (cont'd)

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $15,690 and $108,886, respectively, on sales of Class A shares of
the Fund during the year ended December 31, 1998, and that MetLife Securities,
Inc. earned commissions aggregating $145,513 on sales of Class B shares, and
that the Distributor collected contingent deferred sales charges aggregating
$49,228 on redemptions of Class B shares during the same period.


Note 6

Under normal circumstances at least 80% of the Fund's net assets will be
invested in New York Municipal Obligations. New York State and New York City
face potential economic problems due to various financial, social, economic and
political factors which could seriously affect their ability to meet continuing
obligations for principal and interest payments. Also, the Fund is able to
invest up to 25% of total assets in a single industry. Accordingly, the Fund's
investments may be subject to greater risk than those in a fund with more
restrictive concentration limits.


Note 7

At December 31, 1998, investments totalling 12.2% of the Fund's net assets were
insured as to the timely payment of principal and interest by Municipal Bond
Investors Assurance Corp. (MBIA).


Note 8

The Trustees have the authority to issue an unlimited number of shares of
beneficial interest, $.001 par value per share. At December 31, 1998, the
Distributor owned 59,032 Class C shares of the Fund.

Share transactions were as follows:

REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees of State Street Research
Tax-Exempt Trust and the Shareholders of
State Street Research New York Tax-Free Fund

 

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, 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 State Street Research New York
Tax-Free Fund (a series of State Street Research Tax-Exempt Trust, hereafter
referred to as the "Trust") at December 31, 1998, and the results of its
operations, the changes in its net assets and the financial highlights for 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 Trust'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 December 31, 1998 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.

STATE STREET RESEARCH NEW YORK TAX-FREE FUND
- --------------------------------------------------------------------------------
MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

State Street Research New York Tax-Free Fund had a strong year. Class A shares
returned 5.92% [does not reflect sales charge] for the 12 months ended December
31, 1998. This total return performance was higher than that of the average New
York municipal debt fund tracked by Lipper Analytical Services, which returned
5.64% for the same period. The Lehman Brothers Municipal Bond Index gained
6.48% for the same period.

The Fund currently invests in tax-exempt debt obligations issued by or on
behalf of New York state, New York City or the political subdivisions and other
governmental agencies of either jurisdiction.

The manager added value by lengthening the Fund's duration, by raising the
Fund's overall quality, and by focusing on the structure of each bond added to
the portfolio. Turnover was low, and few major changes were made to the
portfolio for the year.

December 31, 1998


Keep in mind that past performance is no guarantee of future results. 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 gain
distributions and income dividends at net asset value. Performance reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B share or 1%
Class C share contingent deferred sales charge, where applicable. The fund's
returns include performance before the creation of share classes. If this
performance reflected the share classes' current 12b-1 fees, the fund's returns
may have been lower. Class S shares, offered without a sales charge, are
available only through certain employee benefit plans and special programs. The
Lehman Brothers Municipal Bond Index is comprised of 8,000 fixed-rate
investment-grade municipal bonds, all from issues larger than $50 million and
with maturities greater than two years. The index is unmanaged and does not
take sales charges into consideration. Direct investment in the index is not
possible; results are for illustrative purposes only. Performance results for
the Fund are increased by the voluntary reduction of Fund fees and expenses;
without subsidization, performance would have been lower.

                        The Lehman Municipal Bond Index

This report is prepared for the general information of current shareholders.

When used as supplemental sales literature, this publication must be preceded or
accompanied by a current State Street Research New York Tax-Free Fund
prospectus. The prospectus contains more complete information, including sales
charges and expenses. Please read the prospectus carefully before investing.

When used after March 31, 1999, this report must be accompanied by a current
Quarterly Performance Update.

individual investors.

considered a rating of fund performance. The survey included mutual fund
complexes that volunteered or were otherwise selected to participate and was not
industry-wide.
