DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, the market's advances were restricted to an
increasingly select group of stocks - primarily in the technology and
communications areas. Even those gains were accompanied by tremendous levels of
daily volatility. But many other stocks, including the household blue-chip
names, fell in response to a tough combination of investor apathy, rising
interest rates and earnings concerns.

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

In this same period, bonds struggled through one of their worst years in more
than two decades, as the strength of the U.S. economy and the rebound of many
others around the world provoked inflation fears. Though their longer-term
outlook looks brighter, in many instances bond mutual fund investors have
actually lost a little ground or made only slight advances lately.

While we expect the market to broaden eventually, we also expect more
volatility. More than ever, this type of environment calls for investment
diversification. Since not all parts of your portfolio will perform equally well
all the time, we believe it is important to allocate your assets among different
types of investments and funds that target a variety of market segments. This
strategy, executed under the guidance of a seasoned investment professional,
could provide you with a better chance of both realizing results and weathering
the market's changing conditions.

The market's disappointingly narrow focus has created a widening gap in
investment performance. Keep that in mind as you read the report from your
fund's portfolio management team on the following pages. It's all too easy to
get caught up in the headlines and miss what lies underneath.

Sincerely,

/s/Maureen R. Ford

                  Climbing interest rates hurt municipal bonds
                  --------------------------------------------

It has been a rough road for municipal bonds over the last six months as the
Federal Reserve continued to raise interest rates in an attempt to put the
brakes on inflationary pressures and an overheating economy. Although some
commodity prices such as oil have spiked up, overall inflation still appears to
be under control. Nonetheless, the Federal Reserve's preemptive interest-rate
hikes drove bond prices down during the period.

         Also adding to the downward pressure on municipal bonds was the lack of
liquidity in the market. Cash flow into muni bonds virtually dried up as
investors became disenchanted with falling bond prices and were enticed into the
stock market by higher returns.

Fund performance

Given the market backdrop, municipal bonds posted disappointing returns for the
period. For the six months ended February 29, 2000, John Hancock California
Tax-Free Income Fund's Class A, Class B and Class C shares returned -0.62%,
- -0.99% and -1.05%, respectively, at net asset value. However, those returns did
outpace the average California municipal bond fund's return of -1.40% 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 longer-term performance information.

Performance scorecard

In this difficult environment, the Fund benefited from managing the
interest-rate sensitivity - or duration - of the portfolio. The shorter the
duration, the less sensitive the Fund will be to interest-rate changes. From
September through December, we shortened the Fund's duration, which protected
the Fund when rates climbed in the back half of the year. We began to cautiously
push out the Fund's duration to a neutral position at the start of this year
since, although there are still more rate hikes to come, a goodly portion is
already priced into the market.

         The Fund's construction/development holdings also performed well, which
was not surprising given the strong economic growth of the state. The Bonita
Canyon project, for example, is ahead of schedule and demand for the space
continues to exceed expectations. Unfortunately, because of the lackluster
demand for municipal

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

bonds in the last several months, the strength of these construction/development
credits has not been fully reflected in their prices. So we expect more upside
potential as investors begin to recognize the true value of these credits.

         On the negative side, the Fund's health-care holdings were a
disappointment. Federal reductions in Medicare and Medicaid reimbursements
turned out to be more severe than industry experts - and even the government -
had anticipated. And that has put considerable pressure on the earnings in the
health-care sector, particularly hospitals, nursing homes and assisted living
centers.

Restructuring the portfolio

It's important to remember, especially in a tough market, that bond prices will
eventually turn around. So it's critical to maintain a long-term investment
perspective and to consistently focus on positioning the Fund for the future.
Given that, we've taken advantage of rising interest rates and the downturn in
the municipal bond market to begin to gradually restructure the portfolio.

         To start, the jump in interest rates has allowed us to trade some of
our lower-yielding bonds for higher-yielding ones, improving the overall yield
of the portfolio. Second, we've boosted activity in our ongoing strategy to
improve the Fund's call protection. Call protection guards against a bond's
being redeemed by the issuer for a certain period of time. Good call protection
is important 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, then investors are forced to reinvest their money in bonds with
lower yields. Weak bond markets are good for the disciplined investor, because
negative price action often

diverts attention from factors like coupon structure and call protection. It is
the perfect time to add long-term value at inexpensive levels.

         While rates have recently been on the rise, overall inflation is still
very contained by historical standards. A proactive Fed has proven to be a boon
to bond investors over time. As they say, what goes up, comes back down. When
rates do, the Fund will be well positioned with strong call protection.

State status

We're optimistic about the prospects for California. Because of its strong
economic growth, the state's credit rating was recently upgraded to AA by
Fitch/IBCA. Fiscally, California is in excellent shape.
Stronger-than-anticipated revenue growth has allowed the state to rebuild
reserve funds. Plus, the sheer strength and diversity of the state's economy
places it in a strong position to withstand any sort of economic slowdown.

Bond outlook

In the short-term, bond investors could be in for a bumpy ride. The Federal
Reserve has clearly indicated that it is concerned about an overheating economy
and budding inflation. Given that, we believe that the Federal Reserve is likely
to boost interest rates at least one more time this year. Concerns about rising
rates are likely to keep investors nervous and the bond market volatile in the
near term.

         As for municipal bonds, the technical conditions are improving. For
starters, the supply/demand factors in the municipal market are improving. In
1999, new issuance dropped 25%. So far in 2000, it's down roughly 40%. As demand
for municipal bonds begins to pick up, municipal bonds will be harder to come by
and that is likely to drive prices higher.

         In addition, higher interest rates will eventually put a damper on the
economy's strong growth. When that happens, we are likely to see interest rates
peak and eventually resume their decline. Our discipline is to stay fully
invested, and we will also continue to restructure the portfolio so that it is
well positioned when the market does turn the corner.

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

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). Class C
performance includes 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.

Notes to Performance

(1) The Adviser voluntarily reduced a portion of the management fee, the
    Distributor reduced the distribution and service fees applicable to
    Class B shares and custodian fees were offset with balance credits
    during the period. Without the reduction of expenses, and the offset,
    the average annual total return for the one-year, five-year and
    ten-year periods for Class A shares would have been (7.30%), 6.70% and
    6.18%, respectively. Without the reduction of expenses and the offset,
    the average annual total returns for the one-year, five-year and since
    inception periods for Class B shares would have been (8.35%), 6.55% and
    5.40%, respectively. Without the reduction of expenses and the offset,
    the cumulative total return for Class C shares since inception would
    have been (5.27%). Without the reductions of expenses and the offset,
    the yield for Class A, Class B and Class C shares would have been
    4.71%, 4.09% and 4.09%, respectively.

(3)  Assumes dividend reinvestment and does not reflect the effect of sales charges.
(4)  An estimated total return calculation that does not take into consideration
     fee reductions by the
     Adviser during the periods shown.
(5)  Unreimbursed, without fee reduction.
(6)  Portfolio turnover excludes merger activity.
(7)  Not annualized.
(8)  Annualized.
(9)  Effective August 31, 1996, the fiscal period end changed from December 31 to
     August 31.

(10) For the period ended August 31, 1996 and the years ended August
     31, 1998 and 1999, the ratio of expenses to average net assets for the
     Fund excludes the effect of balance credits described in Note B. If
     these expense reductions were included, the ratio of expenses to
     average net assets would have been 0.75% for Class A, 1.50% for Class B
     and 1.60% for Class C. For the period ended February 29, 2000, the
     ratio of expenses to average net assets for the Fund also excludes the
     effect of balance credits, which would have been less than 0.01% for
     Class A, Class B and Class C.
(11) Less than $0.01 per share.

              John Hancock Funds - California Tax-Free Income Fund

(UNAUDITED)

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, 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 $8,347,379 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 - $111,795, 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 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.

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 borrowing. In
addition, a commitment fee based on the average daily unused portion of the line
of credit is allocated among the participating funds. The maximum loan balance
outstanding during the period amounted to $4,595,700. The annualized interest
rate charged during the period ranged from 5.875% to 6.250%. At February 29,
2000, 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 February 29, 2000, there were no open positions in financial futures
contracts.

OPTIONS The Fund may buy or sell options 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 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 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

                                       24

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 option transactions for the period ended February
29, 2000.

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 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%, 1.50% and 1.60% of the average net assets attributable to
Class A, Class B and Class C, respectively. Accordingly, the reduction in the
Adviser's fee amounted to $176,988 for the period ended February 29, 2000. This
limitation may not be discontinued until December 31, 2000.

         The Fund has an agreement with its custodian bank under which $739 of
custodian fees have been reduced by balance credits applied during the period
ended February 29, 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 period ended
February 29, 2000, net sales charges received with regard to sales of Class A
shares amounted to $38,488. Out of this amount, $3,773 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $34,592
was paid as sales commissions to unrelated broker-dealers and $123 was paid as
sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. 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 related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended February 29,
2000, contingent deferred sales charges paid to JH Funds amounted to $206,552.

         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
period ended February 29, 2000, contingent deferred sales charges paid to JH
Funds amounted to $247.

         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 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 and Class C 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. Accordingly, the reduction in the distribution and
service amounted to $44,793 for the period ended February 29, 2000. This
limitation may not be discontinued until December 31, 2000. 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.

              John Hancock Funds - California Tax-Free Income Fund


         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 period 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, 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 yearly 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.
