DEAR FELLOW SHAREHOLDERS:

After providing investors with sky-high returns for the last five years, the
financial markets have brought investors back down to earth in 2000. Volatility
ruled during the spring, as rising interest rates and prospects of a slowing
economy finally caught up to pricey growth stocks. As a result, the tech-heavy
NASDAQ Composite Index advanced by only 3.37% through the end of August, while
the Dow Jones Industrial Average lost 1.46% and the Standard & Poor's 500 Index
was up 4.12%.

--------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman, President and Chief
Executive Officer, flush right next to second paragraph.]
--------------------------------------------------------------------------------

But there is a silver lining. Investors have finally turned their attention to
broader swaths of the market, including both blue chip and old economy stocks in
sectors like financials, health care and energy, that combined both strong
fundamentals and less frothy valuation levels. As for bonds, rising interest
rates have kept the broader bond market in flux, but pockets of strength have
emerged there, as well, including municipal bonds and longer-maturity Treasury
bonds. The 30-year bond, for instance, has returned 14.28% since January.

Between now and year end, we expect the market's focus to be on Washington, as
it usually is in an election year. While the presidential election is important,
what warrants more attention is the Federal Reserve Board. The November election
will generate more ink, but won't have anywhere near the impact on financial
markets that further Fed action could. So we'll be watching the economic data to
see whether the Fed has truly wound down its string of interest-rate hikes.

The market's shifts in leadership so far this year highlight one of the key
investment tenets that we can't emphasize enough: investing should be a
marathon, not a sprint. If your portfolio is diversified and you have an
up-to-date financial plan crafted with an investment professional to meet your
goals, it becomes easier to ride out the market's short-term ups and downs. It
could also provide you with a greater chance of success over time.

Sincerely,

/s/Maureen R.Ford

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

After being battered and bruised last fall and winter, municipals rebounded
handsomely this spring and summer. A year ago, investors were spooked by fears
of inflation and rising interest rates. Continually tight labor markets and
strong economic growth continued to fan inflationary fears and the Federal
Reserve Board raised interest rates to cool off the economy - six times from
June 1999 through August 2000. In response, investors pushed bond yields higher
and their prices - which move in the opposite direction of yields - lower.
Rising interest rates also translated into flagging demand for municipals and
most other fixed-income investments, which put further pressure on bond prices.

         But beginning in the spring, the municipal market began to take what
proved to be a sustained turn for the better. The market rallied on expectations
that the Fed might be at or near the end of its nearly 15-month-long campaign to
fight inflation with interest-rate hikes. Most of that optimism stemmed from the
fact that a few key economic indicators - including new and existing home sales,
retails sales and manufacturing activity - appeared to level off after posting
strong gains during most of 1999. Furthermore, significantly increased demand
for municipals from individual investors - many of whom were provoked by stock
market volatility - gave the municipal market a much-needed shot in the arm. The

demand for municipals easily absorbed a diminished supply of them. Flush with
burgeoning tax coffers, state and local governments issued less debt, roughly
20% less than they had from January through August of 1999. Higher interest
rates also acted to curtail issuance because it drove up borrowing and
refinancing costs for issuers. In the end, these factors and others helped
municipal bond returns top stocks during 2000.

         The New York municipal market had other reasons to cheer. Some bonds
issued by the state and New York City agencies received a credit upgrade
recently, helping to boost their gains.

Fund performance

For the year ended August 31, 2000, John Hancock New York Tax-Free Income Fund's
Class A, Class B and Class C shares posted total returns of

5.95%, 5.21% and 5.21%, respectively, at net asset value. By comparison, the
average New York municipal bond fund returned 5.29%, according to Lipper, Inc.1
Keep in mind that your net asset value will be different from the Fund's
performance if you were not invested in the Fund for the entire period and did
not reinvest all distributions. Please see pages six and seven for longer-term
performance information.

Performance review

The Fund's performance was aided by two factors. First, it was well positioned
in some of the bonds that received a credit upgrade during the year, such as
state-issued securities and New York City Municipal Water Finance Authority
bonds. They posted better-than-average gains as a result of the positive credit
development.

         Our timely management of the Fund's duration, or interest-rate
sensitivity, also paid off. Throughout periods when interest rates were on the
rise and the municipal market was in retreat - such as last fall, the
December-January period and the March-April span - we shortened the Fund's
duration. By doing so during those downdrafts, the Fund's share price losses
were curtailed when interest rates rose. We also benefited from increasing the
Fund's interest-rate sensitivity when the market rallied, as it has since May.
Lengthening the Fund's duration meant that it more fully benefited from the rise
in bond prices.

         On the flip side, our weighting in health-care bonds, although small,
detracted from performance. As they have for some time now, health-care issues
remained under pressure due to increasingly competitive conditions and cutbacks
in medical cost reimbursement by Medicare, HMOs and other payers.

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

Coupon strategy

One of the most important things we evaluate when selecting bonds for the Fund
is their structure, including such elements as their maturity, how much interest
they pay and whether or not they are redeemable before maturity. The past year
was a good illustration of how structural characteristics can determine a bond's
performance.

         In the first half of the year, we emphasized premium coupon bonds,
which pay interest rates above prevailing rates. That proved to be a plus
because their relatively high coupons helped cushion them against price declines
caused by rising interest rates. In addition, many municipal bond prices fell so
much that they started to lose eligibility for the more favorable tax treatment
known as "de minimus." A difficult market environment exposed more and more
bonds to this obscure tax law and placed a lot of pressure on bonds that fell
outside of "de minimus." Premium coupon bonds, however, were mostly immune to
that problem.

         In the second half of the period, we began to add more discount bonds.
Because these bonds paid interest rates below prevailing rates in a rising rate
environment, they were selling at a relatively deep discount to their face value
at the time. We viewed that as an opportunity to pick up some very attractively
priced discount bonds that also offered the benefit of helping to extend our
duration.

Outlook

Over the very short term, we think interest rates can hold steady at current
levels. It would be quite surprising to see the Fed cut or hike interest rates
prior to the November presidential election. Beyond that point, however,
anything can happen. While the economy has shown some signs of a slowdown, it
may not be enough to prevent the Fed from raising interest rates further by year
end. Some observers are speculating that the slowing has been significant enough
to warrant a rate cut, something we believe is unlikely given that economic
growth remains strong. With that outlook in mind, we plan to keep the Fund's
duration neutral. As for the municipal market, we think the technical aspects of
supply and demand will remain favorable.

                             A LOOK AT PERFORMANCE
--------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock New York Tax-Free Income Fund. Total return
measures the change in value of an investment from the beginning to the end of a
period, assuming all distributions were reinvested.

For Class A shares, total return figures include an up-front maximum applicable
sales charge of 4.50%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years). Class C
performance includes an up-front sales charge of 1% and a contingent deferred
sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them.

Please read your prospectus carefully before you invest or send money. Please
note that a portion of the Fund's income may be subject to taxes, and some
investors may be subject to the Alternative Minimum Tax (AMT). Also note that
capital gains are taxable.

Note to Performance

(1) The Adviser has voluntarily reduced a portion of the management fee and a
portion of the custodian fee has been offset by balance credits during the
period. Without the reduction of expenses and the offset, the average annual
total returns for the one-year, five-year and ten-year periods for Class A
shares would have been (3.30%), 4.02% and 5.68%, respectively. The average
annual total returns for the one-year and since inception periods for Class B
shares would have been (4.23%) and 2.90%, respectively. The average annual total
returns for the one-year and since inception periods for Class C shares would
have been (1.36%) and (2.04%), respectively. Without the reduction of expenses,
the yields for Class A, Class B and Class C shares would have been 4.23%, 3.75%
and 3.71%, respectively.

                    WHAT HAPPENED TO A $10,000 INVESTMENT...
--------------------------------------------------------------------------------

The charts on the right show how much a $10,000 investment in the John Hancock
New York Tax-Free Income Fund would be worth, assuming all distributions were
reinvested for the period indicated. For comparison, we've shown the same
$10,000 investment in the Lehman Brothers Municipal Bond Index - an unmanaged
index that includes approximately 15,000 bonds and is commonly used as a measure
of bond performance. It is not possible to invest in an index. Past performance
is not indicative of future results.

==========================NOTES TO FINANCIAL STATEMENTS=========================

               John Hancock Funds - New York Tax-Free Income Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock New York Tax-Free Income Fund (the "Fund") is a diversified series
of John Hancock Tax-Exempt Series Fund (the "Trust"), an open-end management
investment company registered under the Investment Company Act of 1940. The
investment objective of the Fund is to provide as high a level of current income
exempt from both federal income taxes and New York personal income taxes as is
consistent with preservation of capital.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses subject to the approval of the Trustees may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

         Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. Aggregate cash balances
are invested in one or more repurchase agreements, whose underlying securities
are obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $763,997 of a capital loss
carryforward available to the extent provided by regulations, to offset future
net realized capital gains. To the extent that such carryforwards are used by
the Fund, no capital gain distributions will be made. The entire amount of the
loss carryforward expires August 31, 2008. Additionally, net capital losses of
$142,510 attributable to security transactions occurring after October 31, 1999
are treated as arising on the first day (September 1, 2000) of the Fund's next
taxable year.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at time of disposition.

==========================NOTES TO FINANCIAL STATEMENTS=========================

               John Hancock Funds - New York Tax-Free Income Fund


CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the relative net assets of the respective classes. Distribution
and service fees, if any, are calculated daily at the class level based on the
appropriate net assets of each class and the specific expense rate(s) applicable
to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and relative
size of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund has entered into
a syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the year ended August 31, 2000.

OPTIONS The Fund may purchase or sell option contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options will be valued at the mean between
the last bid and asked prices. Upon the writing of a call or put option, an
amount equal to the premium received by the Fund will be included in the
Statement of Assets and Liabilities as an asset and corresponding liability. The
amount of the liability will be subsequently marked to market to reflect the
current market value of the written option.

         The Fund may use option contracts to manage its exposure to the price
volatility of financial instruments. Writing puts and buying calls will tend to
increase the Fund's exposure to the underlying instrument and buying puts and
writing calls will tend to decrease the Fund's exposure to the underlying
instrument, or hedge other Fund investments.

         The maximum exposure to loss for any purchased options will be limited
to the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

         Risks may also arise if counterparties do not perform under the
contract's terms ("credit risk"), or if the Fund is unable to offset a contract
with a counterparty on a timely basis ("liquidity risk"). Exchange-traded
options have minimal credit risk as the exchanges act as counterparties to each
transaction, and only present liquidity risk in highly unusual market
conditions. To minimize credit and liquidity risks in over-the-counter option
contracts, the Fund will continuously monitor the creditworthiness of all its
counterparties.

         At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's year-end
Statement of Assets and Liabilities.

         At August 31, 2000, there were no written option transactions.

NOTE B -
MANAGEMENT FEE AND TRANSACTION
WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.500% of the first $250,000,000 of the
Fund's average daily net asset value, (b) 0.450% of the next $250,000,000, (c)
0.425% of the next $500,000,000, (d) 0.400% of the next $250,000,000 and (e)
0.300% of the Fund's average daily net asset value in excess of $1,250,000,000.

==========================NOTES TO FINANCIAL STATEMENTS=========================

               John Hancock Funds - New York Tax-Free Income Fund


         Effective January 1, 2000, the Adviser has voluntarily agreed to limit
the Fund's expenses to the extent required to prevent expenses from exceeding
0.80%, 1.50% and 1.50% of the average net assets attributable to Class A, Class
B and Class C, respectively. Prior to January 1, 2000, the expense limitations
were 0.70%, 1.40% and 1.40% of the average net assets attributable to Class A,
Class B and Class C, respectively. Accordingly, for the year ended August 31,
2000, the reduction in the Adviser's fee collectively with any additional
amounts not borne by the Fund by virtue of the expense limit amounted to
$156,359. This limitation may not be discontinued until December 31, 2000.

         The Fund has an agreement with its custodian bank under which $33,258
of custodian fees have been reduced by balance credits applied during the year
ended August 31, 2000. If the Fund had not entered into this agreement, the
assets not invested on which these balance credits were earned could have
produced taxable income.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the year ended
August 31, 2000, net sales charges received with regard to sales of Class A
shares amounted to $22,309. Out of this amount, $2,100 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $4,314
was paid as sales commissions to unrelated broker-dealers and $15,895 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder of
Signator Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended August 31, 2000,
the CDSCs amounted to $36,505.

         Effective May 1, 2000, all Class C retail purchases are assessed a
1.00% up-front sales charge. For the year ended August 31, 2000, up-front sales
charges received with regard to sales of Class C shares amounted to $2,755. Out
of this amount, $2,735 was paid as sales commissions to unrelated broker-dealers
and $20 was paid as sales commissions to sales personnel of Signator Investors.
Class C shares which are redeemed within one year of purchase will be subject to
a CDSC at a rate of 1.00% of the lesser of the current market value at the time
of redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSC are paid to JH Funds and are used in whole or in part to
defray its expenses related to providing distribution related services to the
Fund in connection with the sale of Class C shares. For the year ended August
31, 2000, the CDSCs amounted to $2,657.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the year was at
an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Stephen L. Brown, Ms. Maureen R. Ford and Mr. Richard S. Scipione
are directors and/or officers of the Adviser and/or its affiliates, as well as
Trusteesof the Fund. The compensation of unaffiliated Trustees is

borne by the Fund. The unaffiliated Trustees may elect to defer, for tax
purposes, their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. The investment had no impact on the operations
of the Fund.

NOTE C -

investments aggregated $2,233,362 and $186,326, respectively, resulting in net
unrealized appreciation of $2,047,036.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 2000, the Fund has reclassified amounts to
reflect an increase in accumulated net realized loss on investments of $7,752,
an increase in undistributed net investment income of $1,430 and an increase in
capital paid-in of $6,322. This represents the amount necessary to report these
balances on a tax basis, excluding certain temporary differences, as of August
31, 2000. Additional adjustments may be needed in subsequent reporting periods.
These reclassifications, which have no impact on the net asset value of the
Fund, are primarily attributable to certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles. The calculation of net investment income per
share in the financial highlights excludes these adjustments.

REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of
Trustees of John Hancock New York Tax-Free Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments (except for Moody's and Standard & Poor's ratings
and yields at market), 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 the John Hancock New York Tax-Free Income
Fund (the "Fund") at August 31, 2000, the results of its operations, the changes
in its net assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United States of
America. These financial statements and financial highlights (hereafter referred
to as "financial statements") are the responsibility of the Fund's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements in
accordance with auditing standards generally accepted in the United States of
America, 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 owned at August 31, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

DEAR FELLOW SHAREHOLDERS:

After providing investors with sky-high returns for the last five years, the
financial markets have brought investors back down to earth in 2000. Volatility
ruled during the spring, as rising interest rates and prospects of a slowing
economy finally caught up to pricey growth stocks. As a result, the tech-heavy
NASDAQ Composite Index advanced by only 3.37% through the end of August, while
the Dow Jones Industrial Average lost 1.46% and the Standard & Poor's 500 Index
was up 4.12%.

--------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman, President and Chief
Executive Officer, flush right next to second paragraph.]
--------------------------------------------------------------------------------

But there is a silver lining. Investors have finally turned their attention to
broader swaths of the market, including both blue chip and old economy stocks in
sectors like financials, health care and energy, that combined both strong
fundamentals and less frothy valuation levels. As for bonds, rising interest
rates have kept the broader bond market in flux, but pockets of strength have
emerged there, as well, including municipal bonds and longer-maturity Treasury
bonds. The 30-year bond, for instance, has returned 14.28% since January.

Between now and year end, we expect the market's focus to be on Washington, as
it usually is in an election year. While the presidential election is important,
what warrants more attention is the Federal Reserve Board. The November election
will generate more ink, but won't have anywhere near the impact on financial
markets that further Fed action could. So we'll be watching the economic data to
see whether the Fed has truly wound down its string of interest-rate hikes.

The market's shifts in leadership so far this year highlight one of the key
investment tenets that we can't emphasize enough: investing should be a
marathon, not a sprint. If your portfolio is diversified and you have an
up-to-date financial plan crafted with an investment professional to meet your
goals, it becomes easier to ride out the market's short-term ups and downs. It
could also provide you with a greater chance of success over time.

Sincerely,

/s/Maureen R. Ford

                    Municipal bonds rebound as economy slows
                    ----------------------------------------

Fixed-income markets, including municipal bonds, struggled last fall and winter,
as the Federal Reserve attempted to put the brakes on inflationary pressures and
a robust economy by raising interest rates. Municipal bonds also suffered as
investor demand flagged. Beginning in May, however, economic indicators began to
soften - and the tide started to turn for municipal bonds. Hopes that the Fed's
tightening cycle was nearing an end fueled a rally in bonds, and municipals
rebounded as investor worries about inflation pressures eased.

         Municipal performance was also boosted by the increasingly favorable
supply/demand situation. With state and local governments issuing, on average,
about 20% less debt this year, supply wasn't able to keep pace with the demand
surge that occurred as the market rallied. This phenomenon drove prices higher
in the municipal market.

         Despite their recent turnaround, however, municipal bonds weren't able
to keep pace with their taxable counterparts. A shrinking supply of 30-year
Treasuries drove prices up and yields down on the long end of the yield curve,
while interest rates rose at the short end. The end result was a rare inversion
of the yield curve - that is, short-term bonds paid higher yields than long-term
bonds. Against this backdrop, municipal performance lagged, causing the

to-municipal yield ratio to reach some of the cheapest levels in the past
decade. Municipal performance suffered as crossover buyers exited the
tax-exempts to seek the improved returns available in long Treasuries.

A look at performance

Although municipal bonds didn't fare as well as their taxable counterparts, they
still posted solid returns for the period. For the year ended August 31, 2000,
John Hancock Massachusetts Tax-Free Income Fund's Class A, Class B and Class C
shares returned 5.16%, 4.43% and 4.43%, respectively, at net asset value. By
comparison, the average Massachusetts municipal bond fund returned 5.15% for the
same period, according to Lipper, Inc.1 Keep in mind that your net asset value
return will be different from the Fund's performance if you were not invested in
the Fund for the entire period and did not reinvest all

distributions. Please see pages six and seven for historical performance
information.

         While the Fund turned in respectable returns for the year, a couple of
things held performance back. In anticipation of further interest-rate
increases, we kept the Fund positioned relatively defensively with a shorter
duration. Duration measures the Fund's sensitivity to interest-rate changes. The
shorter the duration, the less the Fund's net asset value will fluctuate with
interest-rate changes. While the shorter duration definitely helped to protect
the Fund early in the period when rates were rising, it held back our
performance when munis rebounded this spring. In addition, we had a sizeable
position in lower-quality credits, which underperformed during the period. As
interest rates rose in the past year, many investors deserted lower-grade bonds
for higher credit quality, resulting in widening credit spreads. As a result,
lower-rated bonds lagged and our position in this arena hampered performance.

Responding to market dynamics

With market dynamics shifting throughout the period, we responded by shifting
the portfolio strategy. As we discussed above, we decreased the Fund's
interest-rate sensitivity by shortening our duration early in the period when
interest rates were climbing. While in hindsight we waited too long to lengthen
duration, we have recently begun to increase the Fund's interest-rate
sensitivity. Evidence of a slowing economy is gradually building, and we believe
the Fed is at or near the end of the tightening cycle. With this outlook, there
is substantial upside potential in the municipal market, and an increased
sensitivity to rate changes will prepare the Fund to take advantage of this
change.

         While our lower-quality holdings did detract somewhat from our total
return performance

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

this year, we plan on maintaining our stake in these names. This sector has
provided an important source of both total return and interest income to the
Fund. Once interest rates decline again, we expect this sector to return to its
position as a major contributor to performance.

         Finally, as we've discussed in past reports, we've continued to focus
on adding more call protection to the Fund. Call protection guards against a
bond being redeemed by its issuer for a certain period of time. Good call
protection is especially important in periods when interest rates are falling
because issuers often try to refinance their bonds at lower interest rates. If a
bond gets "called away" or redeemed early, investors are forced to reinvest
their money in bonds with lower yields. With the economy slowing, we believe
that interest rates are at some point likely to resume their decline. When that
happens, the Fund's strong call protection will serve to protect shareholders'
coupon payment stream.

Massachusetts market

Looking ahead, we're likely to see bond issuance increase in Massachusetts
toward the latter part of the year. Much of this spending will be at the state
level, with major transportation projects like the Central Artery Project and
the widening of Route 3 leading the pack. However, much of this debt will be
issued as revenue bonds, thus protecting the state's general obligation rating.
This will also add some new "names" to the Massachusetts market. Though the
influx of supply may put some temporary pressure on the Massachusetts market, it
should be looked at as a buying opportunity to add attractive credits rather
than as a long-term negative.

A look ahead

Evidence is mounting that the U.S. economy is beginning to slow. Clearly the
Federal Reserve is aiming for a soft landing, a strategy that has been
successfully implemented in recent years. However, after six rate increases, the
Fed is likely approaching the tail end of this cycle. This should bode well for
bonds over the next six to 12 months. We have always felt that the latter part
of 2000 would bring an improved scenario for bonds. Indeed, the recent
volatility in the equity markets has led many investors to reconsider their
asset allocation and to increase their bond holdings in order to add more
stability to their portfolios.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Massachusetts Tax-Free Income Fund. Total
return measures the change in value of an investment from the beginning to the
end of a period, assuming all distributions were reinvested.

For Class A shares, total return figures include an up-front maximum applicable
sales charge of 4.50%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years). Class C
performance includes an up-front sales charge of 1% and a contingent deferred
sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them.

Please read your prospectus carefully before you invest or send money. Please
note that a portion of the Fund's income may be subject to taxes, and some
investors may be subject to the Alternative Minimum Tax (AMT). Also note that
capital gains are taxable.

Note to Performance

(1) The Adviser has voluntarily reduced a portion of the management fee
    and a portion of the custodian fee has been offset by balance credits
    during the period. Without the reductions of expenses, the average
    annual total returns for the one-year, five-year and ten-year periods
    for Class A shares would have been (3.78%), 4.10% and 5.64%,
    respectively. The average annual total return for the one-year period
    and since inception for Class B shares would have been (4.72%) and
    3.12%, respectively. The average annual total return for the one-year
    period and since inception for Class C shares would have been (1.90%)
    and (2.40%), respectively. Without the reductions of expenses, the
    yield for Class A, Class B and Class C shares would have been 4.38%,
    3.90% and 3.86%, respectively.

                    WHAT HAPPENED TO A $10,000 INVESTMENT...
--------------------------------------------------------------------------------

The charts on the right show how much a $10,000 investment in the John Hancock
Massachusetts Tax-Free Income Fund would be worth, assuming all distributions
were reinvested for the period indicated. For comparison, we've shown the same
$10,000 investment in the Lehman Brothers Municipal Bond Index - an unmanaged
index that includes approximately 15,000 bonds and is commonly used as a measure
of bond performance. It is not possible to invest in an index. Past performance
is not indicative of future results.

repurchased during the last two periods, along with the corresponding dollar
value.

            John Hancock Funds - Massachusetts Tax-Free Income Fund


NOTE A -
ACCOUNTING POLICIES

John Hancock Massachusetts Tax-Free Income Fund (the "Fund") is a diversified
series of John Hancock Tax-Exempt Series Fund (the "Trust"), an open-end
management investment company, registered under the Investment Company Act of
1940. The investment objective of the Fund is to provide as high a level of
current income exempt from both federal income taxes and Massachusetts personal
income taxes as is consistent with preservation of capital.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

         Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. Aggregate cash balances
are invested in one or more repurchase agreements, whose underlying securities
are obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $373,088 of capital loss carryforwards
available, to the extent provided by regulations, to offset future net realized
capital gains. To the extent such carryforwards are used by the Fund, no capital
gains distribution will be made. The carryforwards expire as follows: August 31,
2003 - $41,406, August 31, 2004 - $137,277, August 31, 2005 - $6,645 and August
31, 2008 - $187,760.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the fund level and allocated daily to each class of
shares based on the relative net assets of the respective classes. Distribution
and service fees, if any, are calculated daily at

                                       19

==========================NOTES TO FINANCIAL STATEMENTS=========================

            John Hancock Funds - Massachusetts Tax-Free Income Fund


the class level based on the appropriate net assets of each class and the
specific expense rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and relative
sizes of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund has entered into
a syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowings. In
addition, a commitment fee is charged to each fund based on the average daily
unused portion of the line of credit and is allocated among the participating
funds. The Fund had no borrowing activity for the year ended August 31, 2000.

OPTIONS The Fund may purchase or sell option contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options are valued at the mean between the
last bid and asked prices. Upon the writing of a call or put option, an amount
equal to the premium received by the Fund will be included in the Statement of
Assets and Liabilities as an asset and corresponding liability. The amount of
the liability will be subsequently marked to market to reflect the current
market value of the written option.

         The Fund may use option contracts to manage its exposure to the price
volatility of financial instruments. Writing puts and buying calls will tend to
increase the Fund's exposure to the underlying instrument, and buying puts and
writing calls will tend to decrease the Fund's exposure to the underlying
instrument, or hedge other Fund investments.

         The maximum exposure to loss for any purchased options will be limited
to the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

         Risks may also arise if counterparties do not perform under the
contract's terms ("credit risk"), or if the Fund is unable to offset a contract
with a counterparty on a timely basis ("liquidity risk"). Exchange-traded
options have minimal credit risk as the exchanges act as counterparties to each
transaction, and only present liquidity risk in highly unusual market
conditions. To minimize credit and liquidity risks in over-the-counter option
contracts, the Fund will continuously monitor the creditworthiness of all its
counterparties.

         At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's year-end
Statement of Assets and Liabilities.

         At August 31, 2000 there were no written option transactions.

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS WITH AFFILIATES
AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.500% of the first $250,000,000 of the
Fund's average daily net asset value, (b) 0.450% of the next $250,000,000, (c)
0.425% of the next $500,000,000, (d) 0.400% of the next $250,000,000 and (e)
0.300% of the Fund's average daily net asset value in excess of $1,250,000,000.

         Effective January 1, 2000, the Adviser has voluntarily agreed to limit
the Fund's expenses to the extent required to prevent expenses from exceeding
0.80%, 1.50% and 1.50% of the average net assets attributable to Class A, Class
B and Class C, respectively. Prior to January 1, 2000, the expense limitations
were 0.70%, 1.40% and 1.40% of the

average net assets attributable to Class A, Class B and Class C, respectively.
Accordingly, for the year ended August 31, 2000, the reduction in the Adviser's
fee, collectively with any additional amounts not borne by the Fund by virtue of
the expense limit, amounted to $221,420. This limitation may not be discontinued
until December 31, 2000.

         The Fund has an agreement with its custodian bank under which $4,249 of
custodian fees have been reduced by balance credits applied during the year
ended August 31, 2000. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the year ended
August 31, 2000, net sales charges received with regard to sales of Class A
shares amounted to $63,891. Out of this amount, $8,557 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $1,762
was paid as sales commissions to unrelated broker-dealers and $53,572 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder of
Signator Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended August 31, 2000,
CDSCs amounted to $46,257.

         Effective May 1, 2000, all Class C shares retail purchases are assessed
a 1.00% up-front sales charge. For the year ended August 31, 2000, up-front
sales charges received with regard to sales of Class C shares amounted to
$15,436. Out of this amount, $15,050 was paid as sales commissions to unrelated
broker-dealers and $386 was paid as sales commissions to sales personnel of
Signator Investors. Class C shares which are redeemed within one year of
purchase will be subject to a CDSC at a rate of 1.00% of the lesser of the
current market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSC are paid to JH Funds and are
used in whole or in part to defray its expenses related to providing
distribution related services to the Fund in connection with the sale of Class C
shares. For the year ended August 31, 2000, CDSCs amounted to $472.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the year was at
an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Stephen L. Brown, Ms. Maureen R. Ford and Mr. Richard S. Scipione
are directors and/or officers of the Adviser and/or its affiliates, as well as
Trustees of the Fund. The compensation of unaffiliated Trustees is borne by the
Fund. The unaffiliated Trustees may elect to defer, for tax purposes, their
receipt of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's deferred compensation liability are recorded on the Fund's
books as an

other asset. The deferred compensation liability and the related other asset are
always equal and are marked to market periodically to reflect any income earned
by the investment as well as any unrealized gains or losses. The investment had
no impact on the operation of the Fund.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term securities, during the year
ended August 31, 2000, aggregated $14,161,655 and $13,259,000, respectively.
There were no purchases or sales of obligations of the U.S. government and its
agencies during the year ended August 31, 2000.

         The cost of investments owned at August 31, 2000 for federal income tax
purposes was $73,348,476. Gross unrealized appreciation and depreciation of
investments aggregated $2,238,452 and $1,250,306, respectively, resulting in net
unrealized appreciation of $988,146.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 2000, the Fund has reclassified amounts to
reflect a decrease in accumulated net realized loss on investments of $251, an
increase in undistributed net investment income of $3,983 and a decrease in
capital paid-in of $4,234. This represents the amount necessary to report
balances on a tax basis, excluding certain temporary differences, as of August
31, 2000. Additional adjustments may be needed in subsequent reporting periods.
These reclassifications, which have no impact on the net asset value of the
Fund, are primarily attributable to certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles. The calculation of net investment income per
share in the financial highlights excludes these adjustments.

REPORT OF INDEPENDENT AUDITORS
To the Shareholders and Board of Trustees of
John Hancock Massachusetts Tax-Free Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments (except for Moody's and Standard & Poor's ratings
and yields at market), 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 the John Hancock Massachusetts Tax-Free
Income Fund (the "Fund") at August 31, 2000, the results of its operations, the
changes in its net assets and the financial highlights for the periods
indicated, in conformity with accounting principles generally accepted in the
United States of America. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with auditing standards generally accepted in
the United States of America, 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 owned at August 31, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.
