===============================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 dra-
matic 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 everywherer 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 higher-quality bonds is a perfect example of why all
your eggs shouldn't be in one basket.

Sincerely,

/s/ Edward J. Boudreau, Jr.
EDWARD J. BOUDREAU, JR., CHAIRMAN AND CHIEF EXECUTIVE OFFICER

                 Municipals fare well in rallying bond market,
                      but lag Treasuries amid record supply

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 was somewhat constrained compared to Treasury
bonds, however, as low interest rates resulted in an increased supply of
municipal bonds. During the first six months of 1998, the issuance of municipal
bonds increased more than 50% versus 1997. The reason was 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.


"A healthy bond market buoyed municipal bonds during the past 12 months."

A note below the chart reads "As a percentage of net assets on August 31,
1998."]
- --------------------------------------------------------------------------------

         Even with the supply pressures, municipal bonds turned in solid
performance during the period. For the 12 months ended August 31, 1998, John
Hancock California Tax-Free Income Fund's Class A and Class B shares returned
9.32% and 8.50%, 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
were competitive with the average California municipal bond fund's return of
8.51%, 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
spreads refer 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 Power Authority, one of two co-generation
plants for the Sacramento Municipal Utility District. This project got a boost
when its sister project was completed and gained a credit upgrade.

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 the Fund's share price is to those changes. The
longer the duration, the more sensitive the Fund's share price is to those
changes. 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
early 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
We are optimistic about the prospects for California's municipal bond market for
the remainder of the year. The state's fiscal situation is good, the economy
continues to grow steadily, unemployment is low and the housing market remains
strong. With one-third of U.S. exports to Asia coming from California, there's
been concern that Asia's financial woes might negatively impact certain sectors
of the state's economy. However, because of its diversity, the California
economy has weathered the crisis and there's been minimal impact on the state's
economic growth.

         Of course, we are heading into an election year in California and we
will be keeping a close eye on any pressure that the political process may put
on the state's budget outlook.

         The Federal Reserve has been vigilant about keeping inflation under
control and there's no reason to believe that 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.

This commentary  reflects the views of the portfolio managers through the end of
the Fund's period discussed in this report.  Of course,  the managers' views are
subject to change as market and other conditions  warrant.

1 Figures from Lipper Analytical Services, Inc. include reinvested dividends and
do not take into account sales charges. Actual load-adjusted performance is
lower.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock California 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 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  Minimum Tax (AMT).  Also note
that capital gains are taxable.

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

              John Hancock Funds - California Tax-Free Income Fund


NOTE A -
ACCOUNTING POLICIES
John Hancock California Tax-Free Income Fund (the "Fund") is a diversified
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 California 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 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
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $8,548,263 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. If such carryforwards are used by the Fund,
no capital gains distribution will be made. The carryforwards expire as follows:
August 31, 2001 - $35,453, August 31, 2002 - $277,226, August 31, 2003 -
$5,169,717, August 31, 2004 - $2,378,578, August 31, 2005 - $7,774 and August
31, 2006 - $679,515.

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

              John Hancock Funds - California Tax-Free Income Fund

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 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 Funds 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           85 U.S. Treasury Bonds       LONG                    $73,711
                                                                   =============

At August 31, 1998,  the Fund has deposited  $500,000 par value of City of Davis
Redevelopment Agency,  7.00%,  09-01-24, in a segregated account to cover margin
requirements on open 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 option 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 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 Funds 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. 21

         Risks may also arise if counterparties do not perform under the
contract's terms ("credit risk"), or if the Funds are 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.

         There were no written options 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 at
an annual rate of 0.55% of the Fund's average daily net asset value.

         The Adviser has voluntarily agreed to limit the Fund's operating
expenses to 0.75% and 1.50% of the average net assets attributable to Class A
and Class B, respectively. Accordingly, the reduction in the Adviser's fee
amounted to $219,457 for the year ended August 31, 1998. This limitation may be
discontinued at any time.

         The Fund has an agreement with its custodian bank under which $66,589
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 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, 1998, net sales charges received with regard to sales of Class A
shares amounted to $561,946. Out of this amount, $75,119

was retained and used for printing prospectuses, advertising, sales literature
and other purposes, $440,840 was paid as sales commissions to unrelated
broker-dealers and $45,987 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 $175,197.

         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 at an
annual rate not to exceed 0.15% 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 temporarily agreed to limit the distribution and
service fees pursuant to the Class B plan to 0.90% of the average daily net
assets. 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.

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

              John Hancock Funds - California Tax-Free Income 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 $3,578.


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 $41,324,694 and $38,873,119, 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 (including the joint
repurchase agreement) for federal income tax purposes was $352,703,190. Gross
unrealized appreciation and depreciation of investments aggregated $41,236,928
and $1,220, respectively, resulting in net unrealized appreciation of
$41,235,708.



NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 1998, the Fund has reclassified amounts to
reflect a decrease in accumulated net realized loss on investments of $18,291, a
decrease in distributions in excess of net investment income of $11,531 and a
decrease in capital paid-in of $29,822. 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 California Tax-Free Income Fund


We have audited the accompanying statement of assets and liabilities of the John
Hancock  California  Tax-Free Income Fund (the "Fund") 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 California Tax-Free Income Fund 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.
