===============================CHAIRMAN'S MESSAGE===============================
                    
DEAR FELLOW SHAREHOLDERS:

An often-used analogy for stock market performance over the short term is a
roller coaster. That is because, while long-term history suggests the market's
general direction is up, its swings over the short term can be dramatic and, at
times, violent. Recently, the market has given us a stark example of this
phenomenon. From the new highs set in mid-July, the major indices plunged by 19%
through the end of August. It was the worst such fall since 1990. For the first
time in a number of years, some bonds and bond mutual funds outperformed stocks
and stock mutual funds. Seeking safety in a world of global economic
uncertainties, investors everywhere converged on U.S. Treasury bonds and pushed
their yields to historic lows.

[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
                                                                 

      For the record-breaking number of investors who have entered the market
for the first time since 1990, it was their worst taste of stock market reality.
We are pleased to report that most individual investors did not panic, and we
hope that means they've taken our words to heart. Over the long term, markets do
not move up or down in a straight line. That's why after watching the market
charge ahead almost uninterrupted for so many years, we have been striking a
more cautionary stance in this space over the last several months.

      Analysts are still pondering whether the global turmoil and the prospects
for slower U.S. economic and corporate earnings growth are signs that the long
bull market has finally run its course. While we don't make a practice of
opining on what the market will do next, we continue to believe it would be wise
for investors to set more realistic expectations. Over the long term, the
market's historical results have been more in the 10% per year range, which is
still a solid result, considering it has been produced despite wars, depressions
and other social upheavals along the way.

      There is no doubt, however, that the market's heightened volatility and
recent dramatic moves have been cause for concern. In these uncertain times, it
becomes even harder to remember to "stay the course" and stick to your long-term
investment plan. But this remains the essential tenet of successful investing.
Now could also be a good time to review your asset allocation with your
investment professional, keeping in mind that the last six months' divergence in
performance of stocks and high-quality bonds is a perfect example of why all
your eggs shouldn't be in one basket.

Sincerely,


/s/ Edward J. Boudreau, Jr.

Economic turmoil in Asia, Russia and other emerging markets sent bond yields
lower and bond prices higher during the past 12 months. The Asian meltdown,
which was still in its infancy at the beginning of the period, had two positive
effects on U.S. bonds. First, it helped to cool off inflationary pressures that
were building as a result of robust U.S. economic growth. Bond holders dislike
inflation because it eats away at their fixed-income payments. Second, the
crisis prompted a flood of international investors to seek out the relative
safety of U.S. Treasury bonds. As inflationary fears subsided and the news out
of Asia worsened, investors pushed bond yields -- which move in the opposite
direction of bond prices -- lower from September through December last year.

   As fears about Asia's crisis spilling over into the U.S. subsided somewhat at
the start of this year, inflationary fears once again took center stage.
Investors worried that too much domestic growth would translate into higher
inflation. Throughout much of the spring, bond prices drifted lower. But a
second round of Asian "flu" in the summer buffeted world markets, prompting many
investors to pull money from Asia and Latin America and propel the rally in U.S.
Treasury bonds. Adding further fuel to bonds' advance was the devaluation of the
Russian ruble in mid-August. This

event set off additional buying of U.S. Treasury bonds. Municipals, like
Treasuries, benefited from the benign inflationary environment, falling interest
rates and global economic uncertainty. However, their gains didn't keep pace
with U.S. Treasury bonds because the supply of municipals expanded while demand
remained firm at best. Municipal issuers advantageously issued new and
refinanced older debt at a near-record pace in order to take advantage of low
interest rates. And unlike the U.S. Treasury market, the municipal market did
not experience increased buying from international investors seeking a safe
haven from global turmoil.

Performance review

For the 12-month period ended August 31, 1998, John Hancock High Yield Tax-Free
Fund's Class A and Class B shares posted total returns of 9.34% and 8.53%,
respectively, at net asset value. Keep in mind that your net asset value return
will be different from the Fund's if you were not invested in the Fund for the
entire period and did not reinvest all distributions. The Fund's returns were in
line with the 8.62% return for the average high-yield municipal bond fund for
the same period, according to Lipper Analytical Services, Inc.1 Longer-term
performance information can be found on pages six and seven.

   Among our biggest winners were our zero coupon bond holdings. Dubbed
"zeroes," these bonds make no periodic interest payments. Instead, they are sold
at a deep discount from their face value. Investors receive the rate of return
upon redemption of the bond at face value on a specified maturity date. The
reason for their relatively strong recent performance stems from the fact that
they tend to rally more than interest-bearing bonds when interest rates fall.

   Other strong performers included non-callable bonds and bonds with good call
protection. Non-callable bonds can't be redeemed by their issuer before maturity
and bonds with good call protection cannot be redeemed for some period of time.
Municipal issuers, like homeowners, often refinance their debt when interest
rates fall. Refinancing is usually good for both homeowners and municipal
issuers because it lowers their debt costs. However, refinancing of debt can be
bad for municipal bond holders because they may be forced to reinvest the
proceeds from high-yielding redeemed or "called" bonds at lower prevailing
rates. Our holdings in Tooele County (UT), issued on behalf of Laidlaw Corp.,
for example, gave the Fund good income in the form of a 7.55% yield and they are
protected from being called away for 15 years.

pages for historical performance information.]
- --------------------------------------------------------------------------------

   Our main disappointment were our holdings in housing bonds. As mortgage rates
fell to their lowest levels in 25 years, near-record numbers of homeowners
refinanced. As we mentioned earlier, while good news for homeowners,
refinancings can be difficult for housing bond holders because they may have to
reinvest the proceeds at lower, prevailing rates.

A word about yield

We specifically avoided pushing for additional yield by adding a lot of
low-quality bonds. Generally speaking, the lower a bond's credit quality, the
higher its yield. That's because investors demand more yield as compensation for
taking on more risk that the issuer will not be able to meet its debt
obligations in a timely fashion. In our view, the small amount of incremental
yield currently offered by lower-quality, below-investment-grade bonds just
wasn't enough to compensate us for taking on more credit risk.

Outlook

Our outlook for interest rates, which are the prime determinant of municipal
bond performance, is cautiously optimistic. U.S. economic growth appears to be
slowing, thanks in large part to the problems in Asia, and inflation appears in
check. We believe that the current lack of inflationary pressures should
eliminate the need for the Federal Reserve to raise interest rates. Indeed, if
global economic turmoil continues, the Fed could look to lower rates to prevent
too much of a U.S. slowdown.

   As far as municipal supply goes, we think it will taper off over the next
several months. The real question mark is demand. Municipals currently are
priced very cheaply relative to taxable securities. If demand for munis remains
firm, or strengthens as people look to our market for value, municipals should
have a chance to play catch-up to Treasuries. And as long as interest rates
remain low, we believe that high-yield municipal bonds will continue to
experience stronger demand than their higher-quality, lower-yielding
counterparts and outpace them as a result.

 "Municipals currently are priced very cheaply relative to taxable securities."

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock High Yield Tax-Free 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 a maximum applicable sales
charge of 4.50%. (Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%.) Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years).

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.

The charts on the right show how much a $10,000 investment in the John Hancock
High Yield Tax-Free 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. Past performance is no guarantee of future results.

*   Credit ratings are unaudited and rated by Standard & Poor's where
    available, or Moody's Investors Service, Fitch or John Hancock Advisers,
    Inc. where Standard & Poor's ratings are not available.

**  These securities, having an aggregate value $4,970,960 or 2.89% of the
    Fund's net asset value, have been purchased as forward commitments - that
    is, the Fund has agreed on trade date, to take delivery of and make
    payment for such securities on a delayed basis subsequent to the date of
    this schedule. The purchase price and interest rate of such securities are
    fixed at trade date, although the Fund does not earn any interest on such
    securities until settlement date. The Fund has instructed its Custodian
    Bank to segregate assets with a current value at least equal to the amount
    of the forward commitment. Accordingly, the market value of $5,610,625 of
    South Orange County Public Financing Authority, 7.27%, 08-15-17, has been
    segregated to cover the forward commitment.

+   The yield is not calculated in accordance with guidelines established by
    the U.S. Securities & Exchange Commission and is unaudited. Zero coupon
    yields are at yield to maturity.

#   Represents rate in effect on August 31, 1998.

The percentage shown for each investment category is the total value of that
category as a percentage of the net assets of the Fund.

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

                  John Hancock Funds - High Yield Tax-Free Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock Tax-Free Bond Trust (the "Trust") is a diversified open-end
management investment company registered under the Investment Company Act of
1940. The Trust consists of two series: John Hancock High Yield Tax-Free Fund
(the "Fund") and John Hancock Tax-Free Bond Fund. The other series of the Trust
is reported in separate financial statements. The investment objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with the preservation of capital, by investing primarily
in municipal bonds, notes and commercial paper, the interest on which is exempt
from federal income taxes.

   The Board of Trustees has authorized the issuance of multiple classes of
shares of the Fund, designated as Class A and Class B 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 Board of Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission. Shareholders of a class
which bears distribution and service expenses under terms of a distribution plan
have exclusive voting rights regarding 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 Board of 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's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $9,957,299 of a capital
loss carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent such carryforward is used by
the Fund, no capital gains distribution will be made. The carryforwards expire
as follows: August 31, 2002 -- $2,785,979, August 31, 2003 -- $205,838, August
31, 2004 -- $3,207,633, August 31, 2005 -- $716,668 and August 31, 2006 --
$3,041,181.

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

                  John Hancock Funds - High Yield Tax-Free Fund

Internal Revenue Code. The Fund records market discount on bonds purchased after
April 30, 1993 at 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 appropriate 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 the
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. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $1 billion,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds. The
Fund had no borrowing activity for the year ended August 31, 1998.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates and other market conditions. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling futures
tends to decrease the Fund's exposure to the underlying instrument or hedge
other Fund instruments. At the time the Fund enters into a financial futures
contract, it will be required to deposit with its custodian a specified amount
of cash or U.S. government securities, known as "initial margin," equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract is valued at the official settlement price on the
board of trade or U.S. commodities exchange on which it trades. Subsequent
payments, known as "variation margin," to and from the broker are made on a
daily basis as the market price of the financial futures contract fluctuates.
Daily variation margin adjustments, arising from this "mark to market," will be
recorded by the Fund as unrealized gains or losses.

   When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

   For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

   At August 31, 1998, there were no open positions in financial futures
contracts.

OPTIONS The Fund may purchase options contracts. Listed options will be valued
at the last quoted sales price on the exchange on which they are primarily
traded. Purchased put or call over-the-counter options will be valued at the
average of the "bid" prices obtained from two independent brokers. Written put
or call over-the-counter options will be valued at the average of the "asked"
prices obtained from two independent brokers. 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 options contracts to manage its exposure to changing
security prices. Writing puts and buying calls will tend to increase the Fund's
exposure to the underlying instrument, and buying

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

                  John Hancock Funds - High Yield Tax-Free Fund

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 year 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 Statement of
Assets and Liabilities.

   At August 31, 1998, there were no open written options contracts.

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) 0.625% of the first $75,000,000 of the Fund's
average daily net asset value, (b) 0.5625% of the next $75,000,000 and (c) 0.50%
of the Fund's average daily net asset value in excess of $150,000,000.

   The Fund has an agreement with its custodian bank under which $5,077 of
custodian fees have been reduced by balance credits applied during the year
ended August 31, 1998. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits 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,
1998, net sales charges received with regard to sales of Class A shares amounted
to $225,191. Out of this amount, $27,441 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $178,887 was
paid as sales commissions to unrelated broker-dealers and $18,863 was paid as
sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

   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 5.0% 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 B shares. For the year ended August 31, 1998,
contingent deferred sales charges paid to JH Funds amounted to $367,303.

   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 and Class B 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 0.25% of
Class A average daily net assets and 1.00% of Class B average daily net assets,
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, 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 JHMLICo. The Fund pays
transfer agent fees based on the number of shareholder accounts and certain
out-of-pocket expenses.

                  John Hancock Funds - High Yield Tax-Free Fund

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

   Mr. Edward J. Boudreau Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipone
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 on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At August 31, 1998, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $1,714.

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 fiscal
year ended August 31, 1998, aggregated $59,184,299 and $59,461,210,
respectively. There were no purchases or sales of obligations of the U.S.
government and its agencies during the fiscal year ended August 31, 1998.

   The cost of investments owned at August 31, 1998 for federal income tax
purposes was $158,175,963. Gross unrealized appreciation and depreciation of
investments aggregated $18,994,591 and $2,768,992 respectively, resulting in net
unrealized appreciation of $16,225,599.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 1998, the Fund has reclassified amounts to
reflect an increase in accumulated net realized loss on investments of $8,065,
an increase in distributions in excess of net investment income of $4,338 and an
increase in capital paid-in of $12,403. This represents the amount necessary to
report these balances on a tax basis, excluding certain temporary differences,
as of August 31, 1998. 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 the 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 ERNST & YOUNG LLP, INDEPENDENT AUDITORS 

To the Board of Trustees and Shareholders of 
John Hancock Tax-Free Bond Trust--
  John Hancock High Yield Tax-Free Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock High Yield Tax-Free Fund (the "Fund"), one of the portfolios
constituting John Hancock Tax-Free Bond Trust, including the schedule of
investments, as of August 31, 1998, and the related statement of operations for
the year then ended, the statement of changes in net assets for each of the two
years in the period then ended and the financial highlights for each of the
periods indicated therein. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
August 31, 1998, by correspondence with the custodian and brokers, and other
auditing procedures where replies from brokers were not received. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
John Hancock High Yield Tax-Free Fund of the John Hancock Tax-Free Bond Trust at
August 31, 1998, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended and
the financial highlights for each of the indicated periods, in conformity with
generally accepted accounting principles.

===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

An often-used analogy for stock market performance over the short term is a
roller coaster. That is because, while long-term history suggests the market's
general direction is up, its swings over the short term can be dramatic and, at
times, violent. Recently, the market has given us a stark example of this
phenomenon. From the new highs set in mid-July, the major indices plunged by 19%
through the end of August. It was the worst such fall since 1990. For the first
time in a number of years, some bonds and bond mutual funds outperformed stocks
and stock mutual funds. Seeking safety in a world of global economic
uncertainties, investors everywhere converged on U.S. Treasury bonds and pushed
their yields to historic lows.

[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
                                                                

      For the record-breaking number of investors who have entered the market
for the first time since 1990, it was their worst taste of stock market reality.
We are pleased to report that most individual investors did not panic, and we
hope that means they've taken our words to heart. Over the long term, markets do
not move up or down in a straight line. That's why after watching the market
charge ahead almost uninterrupted for so many years, we have been striking a
more cautionary stance in this space over the last several months.

      Analysts are still pondering whether the global turmoil and the prospects
for slower U.S. economic and corporate earnings growth are signs that the long
bull market has finally run its course. While we don't make a practice of
opining on what the market will do next, we continue to believe it would be wise
for investors to set more realistic expectations. Over the long term, the
market's historical results have been more in the 10% per year range, which is
still a solid result, considering it has been produced despite wars, depressions
and other social upheavals along the way.

      There is no doubt, however, that the market's heightened volatility and
recent dramatic moves have been cause for concern. In these uncertain times, it
becomes even harder to remember to "stay the course" and stick to your long-term
investment plan. But this remains the essential tenet of successful investing.
Now could also be a good time to review your asset allocation with your
investment professional, keeping in mind that the last six months' divergence in
performance of stocks and high-quality bonds is a perfect example of why all
your eggs shouldn't be in one basket.

Sincerely,


/s/ Edward J. Boudreau, Jr.

                               Tax-Free Bond Fund

             Falling interest rates, tame inflation boost municipals

A healthy bond market buoyed municipal bonds during the past 12 months.
Continued slowdown in Asian markets constrained U.S. economic growth, while
turmoil in emerging markets drew investors to the safety of U.S. Treasuries. As
a result, U.S. interest rates fell and inflation remained under control. Against
this positive backdrop, municipal bonds turned in solid returns for the year.

      Municipal performance has been somewhat constrained compared to Treasury
bonds, however, as low interest rates have resulted in an increased supply of
municipal bonds. During the first six months of 1998, the supply of municipal
bonds increased more than 50% versus 1997. The reason is that many local
governments have been issuing large amounts of new tax-exempt bonds in order to
take advantage of lower interest rates. This strong influx of new bond issuance
has put pressure on municipal bond prices, causing them to lag Treasuries.

      The silver lining, however, is that municipal bonds now offer their best
relative values versus U.S. Treasuries in almost five years. This has not gone
unnoticed, particularly among non-traditional buyers who have crossed over into
the tax-exempt market to take advantage of these attractive values. This strong
demand from non-traditional "crossover" buyers has helped to absorb the recent
flood of new issuance into the municipal bond market.

      Even with the supply pressures, municipal bonds turned in a solid
performance during the period. For the 12 months ended August 31,

1998, John Hancock Tax-Free Bond Fund's Class A and Class B shares returned
9.08% and 8.27%, respectively, at net asset value. Keep in mind that your net
asset value return will be different if you were not invested in the Fund for
the entire period and did not reinvest all distributions. The Fund's returns
outpaced the average general municipal bond fund's return of 8.20%, according to
Lipper Analytical Services, Inc.1 Please see pages six and seven for longer-term
performance information.

Narrowing credit spreads drive performance

Credit spreads in the municipal market narrowed substantially in the first six
months of the period. Credit spread refers to the difference in yields between
bonds with different credit ratings. As the gap between yields on higher- and
lower- quality bonds narrowed, the Fund benefited significantly thanks to its
holdings in lower- quality bonds. With in-depth credit analysis, we've been able
to identify lower-quality bonds not only with attractive yields, but also with
improving credit profiles. One of our best performers was the Sacramento
Cogeneration Authority. This cogeneration project completed construction on two
out of three of its power plants and the credit was upgraded.

Focus on portfolio duration and call protection

Throughout the year, we continued to carefully manage the portfolio's duration
and structure. Duration is a measure of how sensitive a bond's price, and
therefore the Fund's share price, is to interest-rate changes. The longer the
duration, the more the price rises when rates fall (and falls when rates rise).
For most of the year, we've kept the Fund's duration relatively long. That way
we could take advantage of falling interest rates and the bond market's strong
rally.

      We also maintained our long-term focus on call protection. As we've
discussed in previous reports, call protection guards a bond from being redeemed
by its issuer for a certain period of time. Strong call protection is especially
important during periods of falling interest rates -- when 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. By focusing on issues with strong call protection, we've been able to
maintain the Fund's competitive yield levels.

Looking ahead

The Federal Reserve has been vigilant about keeping inflation under control, and
there's no reason to believe this will change in the near future. The biggest
question is the direction of

the U.S. economy. We expect that Asia's financial woes will continue to slow the
U.S. economy in the second half of the year. In this environment, we could see
interest rates continue to fall. As a result, we will be biased toward
maintaining our longer duration. In addition, we expect credit spreads to
continue to remain narrow and yield opportunities to be limited. Given our
economic outlook and the narrow spreads in the market, we will be highly
selective in adding yield to the portfolio, instead focusing on higher- quality
credits.

      The macro-environment for municipal bonds also remains favorable. Current
municipal bond prices represent historic values relative to U.S. Treasuries. In
addition, we believe that supply pressures are likely to moderate in the second
half of the year. Once the pace of new issues slows, municipal bonds should have
a chance to improve their performance relative to U.S. Treasuries.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Tax-Free Bond 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 a 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).

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 Maximum Tax (AMT). Also note
that capital gains are taxable.

      this schedule. The purchase price and interest rate of such securities are
      fixed at trade date, although the Fund does not earn any interest on such
      securities until settlement date. The Fund has instructed its Custodian
      Bank to segregate assets with the current value at least equal to the
      amount of its forward commitment. Accordingly, the market values of

      Commonwealth of Puerto Rico, 8.073%, 07-01-11 have been segregated to
      cover the forward commitments.

                     John Hancock Funds - Tax-Free Bond Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock Tax-Free Bond Trust (the "Trust") is a diversified open-end
management investment company registered under the Investment Company Act of
1940. The Trust consists of two series: John Hancock Tax-Free Bond Fund (the
"Fund") and John Hancock High Yield Tax-Free Fund. The other series of the Trust
is reported in separate financial statements. The investment objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with preservation of capital, by investing primarily in
municipal bonds, notes and commercial paper, the interest on which is exempt
from federal income taxes.

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B 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's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $12,768,595 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, 2002 -- $7,117,054 and August 31, 2003 -- $5,651,541.

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.

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

                     John Hancock Funds - Tax-Free Bond 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
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. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $1 billion,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds. At
August 31, 1998, there were no outstanding borrowings.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund enters into a financial futures contract, it will be required to deposit
with its custodian a specified amount of cash or U.S. government securities,
known as "initial margin," equal to a certain percentage of the value of the
financial futures contract being traded. Each day, the futures contract is
valued at the official settlement price on the board of trade or U.S.
commodities exchange on which it trades. Subsequent payments, known as
"variation margin," to and from the broker are made on a daily basis as the
market price of the financial futures contract fluctuates. Daily variation
margin adjustments, arising from this "mark to market," will be recorded by the
Fund as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

      At August 31, 1998, open positions in financial futures contracts were as
follows:

                                                     UNREALIZED
EXPIRATION    OPEN CONTRACTS             POSITION    APPRECIATION
- ----------    --------------             --------    ------------
DEC 98        175 U.S. TREASURY BONDS    LONG          $151,758
                                                      =========

      At August 31, 1998, the Fund has deposited $1,200,000 par value of County
of Clark, 6.50%, 12-01-33 in a segregated account to cover margin requirements
on open financial futures contracts.

OPTIONS The Fund may buy options contracts. Listed options will be valued at the
last quoted sales price on the exchange on which they are primarily traded.
Purchased put or call over-the-counter options will be valued at the average of
the "bid" prices obtained from two independent brokers. Written put or call
over-the-counter options will be valued at the average of the "asked" prices
obtained from two independent brokers. 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


                                       27
<PAGE>

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

                     John Hancock Funds - Tax-Free Bond Fund

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.

      There were no written option transactions for the year ended August 31,
1998.

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) 0.55% of the first $500,000,000 of the Fund's
average daily net asset value, (b) 0.50% of the next $500,000,000 and (c) 0.45%
of the Fund's average daily net asset value in excess of $1,000,000,000.

      The Adviser has voluntarily agreed to limit the Fund's expenses further to
the extent required to prevent expenses from exceeding 0.85% and 1.60% of the
average net assets attributable to Class A and Class B, respectively.
Accordingly, for the year ended August 31, 1998, 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 $147,165. This limitation may be discontinued at
any time.

      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,
1998, net sales charges received with regard to sales of Class A shares amounted
to $645,689. Out of this amount, $79,967 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $181,204 was
paid as sales commissions to unrelated broker-dealers and $384,518 was paid as
sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      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 5.0% 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, 1998
the contingent deferred sales charges received by JH Funds amounted to $287,462.

      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 and Class B 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 0.25% of
Class A average daily net assets and 1.00% of Class B average daily net assets
to reimburse JH Funds for its distribution and service costs. JH Funds has
agreed to limit the distribution and service fees pursuant to Class A and Class
B plans to 0.15% and 0.90% of the average daily net assets, respectively. Up to
a maximum of 0.25% of such payments may be service fees as defined by the
amended

Rules of Fair Practice of the National Association of Securities Dealers. Under
the amended Rules of Fair Practice, 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 JHMLICo. 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 and
financial management services for the Funds. The compensation for the year was
at an annual rate of less than 0.02% of the average net assets of the Fund.

      Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon 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 on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At August 31, 1998 the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $4,423.

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, 1998, aggregated $205,305,328 and $268,831,328, respectively.
There were no purchases or sales of obligations of the U.S. government and its
agencies during the year ended August 31, 1998.

      The cost of investments owned at August 31, 1998 for federal income tax
purposes was $684,101,479. Gross unrealized appreciation and depreciation of
investments aggregated $91,563,794 and $153,312 respectively, resulting in net
unrealized appreciation of $91,410,482.

NOTE D -
REORGANIZATION

On November 14, 1996, the shareholders of John Hancock Managed Tax-Exempt Fund
(JHMTE) approved a plan of reorganization between JHMTE and the Fund providing
for the transfer of substantially all of the assets and liabilities of JHMTE to
the Fund in exchange solely for Class A and Class B shares of the Fund. The
acquisition was accounted for as a tax free exchange of 3,663,041 Class A shares
and 14,270,326 Class B shares of the Fund for the net assets of JHMTE, which
amounted to $38,514,684 and $150,045,343 for Class A and Class B shares,
respectively, including $13,013,699 of unrealized appreciation, after the close
of business on December 6, 1996.

NOTE E -
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 1998, the Fund has reclassified amounts to
reflect an increase in accumulated net realized loss on investments and
financial futures contracts of $7,535,869, an increase in undistributed net
investment income of $1,322,844 and an increase in capital paid-in of
$6,213,025. This represents the amount necessary to report these balances on a
tax basis, excluding certain temporary differences, as of August 31, 1998.
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.
