Dear Fellow Shareholders,

The stock market continued its advance in the first two months of 2004,
prolonging last year's strong rebound after three down years. The same
factors that produced double-digit returns in a broad-based rally in 2003
were still at work in the new year: a rebounding economy, fueled by
historically low interest rates and tax cuts, and improving corporate
earnings. However, the market staged a correction in March that took back the
year's advances and left many wondering what the market would do next. Bonds,
which had their fourth straight year of gains in 2003, albeit on a more
modest scale, also started 2004 on the right foot, producing positive total
returns.

No matter what this year brings, one thing is certain: the stock market has
just experienced nine straight years of very extreme returns. From 1995
through 1999, we saw double-digit returns in excess of 20% per year, only
to have 2000 through 2002 produce ever-increasing negative results,
followed by another 20%-plus gain last year. After such a performance, we
could be in for a more modest, less exciting year. But history also shows
that this pattern is typical. The market, as measured by the Standard &
Poor's 500 Index, has produced average annual results of 10.4% since 1926.
However, that "normal" return is rare in any given year. In fact, since
1926, the S&P 500 has produced returns of 10%-12% in only three calendar
years, according to Ibbotson. The stock market is indeed a market of
extremes.

Although the past in no way predicts the future, we have learned at least
one lesson from history: expect highs and lows in the short term, but
always invest for the long term. Equally important: work with your
financial adviser to maintain a diversified portfolio, spread out among not
only different asset classes -- stocks, bonds and cash -- but also among
various investment styles. It's the best way we know of to benefit from,
and weather, the market's extremes.

Sincerely,

/S/ MAUREEN FORD GOLDFARB

Chairman and Chief Executive Officer

YOUR FUND
AT A GLANCE

The Fund seeks
a high level of
current income,
consistent with
preservation of
capital, that is
exempt from fed-
eral and California
personal income
taxes. In pursu-
ing this goal, the
fund normally
invests at least
80% of its assets
in securities of any
maturity exempt
from federal and
California personal
income tax.

Over the last six months

* The U.S. bond market rallied despite better economic conditions;
  municipal bonds outperformed the major taxable bond sectors.

* The Fund outperformed its benchmark index and peer group average thanks
  to favorable results from its tobacco and essentialservices bonds.

* The Fund also benefited from the strong performance of its longer-term bonds.

BY DIANNE SALES, CFE, AND JAMES T. COLBY III, PORTFOLIO MANAGERS

MANAGERS'
REPORT

JOHN HANCOCK
California Tax-Free Income Fund

The U.S. bond market, and municipal bonds in particular, posted solid gains
during the six months ended February 29, 2004. Contrary to expectations,
bond yields fell amid evidence of a firm economic recovery. A rebound in
manufacturing activity and increased capital spending by corporate America
provided a boost to the economy, which grew at an 8% annual rate in the
third quarter of 2003 -- its strongest quarter in nearly 20 years -- and a
4% annual rate in the fourth quarter.

The notable exception to the generally rosy economic environment was
persistent weakness in the labor market. The lack of job growth cast some
doubt on the sustainability of the recovery and was one reason the Federal
Reserve held short-term interest rates steady at their lowest levels in 45
years. The combination of a "jobless recovery" and stable Fed interest rate
policy led investors to push bond yields lower and bond prices higher
during the six-month period. Municipal bonds outperformed the major taxable
segments of the domestic bond market.

"The U.S. bond market,
 and municipal bonds in
 particular, posted solid
 gains during the six
 months ended February
 29, 2004."

CALIFORNIA'S FISCAL WOES

The six-month period was an eventful one for the state of California. The
legislature struggled to pass a 2004 budget, Governor Gray Davis was
recalled and Arnold Schwarzenegger elected to replace him. And despite a
ballooning budget deficit, the state failed to make any meaningful spending
cuts. As a result, the state of California was downgraded by the major
rating agencies and now has the worst credit rating of any state in the
country. To pay off $14 billion in short-term debt that matures this
summer, the state recently received voter approval to issue $15 billion in
longer-term bonds.

paragraph.]

We believe this is a sensible solution to California's short-term financial
predicament, though it is likely to take several more years for the state
to work through all of its fiscal problems and get its budget back in
order. While the state's fiscal recovery will lag behind that of other
states, the economic recovery in California has kept pace with the rest of
the nation. California is home to the fifth-largest economy in the world,
and we believe the size, breadth and diversity of this economy will ensure
its long-term success.

FUND PERFORMANCE

For the six months ended February 29, 2004, John Hancock California
Tax-Free Income Fund's Class A, Class B and Class C shares posted total
returns of 7.63%, 7.18% and 7.18%, respectively, at net asset value. The
average California municipal debt fund returned 6.90%, according to Lipper,
Inc.,1 while the return of the Lehman Brothers Municipal Bond Index was
6.52%. 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. See pages six and seven for
historical performance information.

TOBACCO AND ESSENTIAL SERVICES LEAD

Favorable security selection in key market sectors contributed to the
Fund's outperformance of the index and its peer group average. In
particular, the portfolio's tobacco-related municipal bonds gained nearly
18% during the six-month period. Tobacco bonds, which are backed by the
proceeds from a legal settlement between 46 states -- including California
- -- and tobacco companies, rebounded sharply after pending litigation
involving one of the major tobacco companies was temporarily resolved.
Unenhanced tobacco bonds comprised about 5% of the portfolio throughout the
period, and we expect to maintain this position going forward.

"Favorable security selec-
 tion in key market sectors
 contributed to the Fund's
 outperformance..."

The portfolio's essential-purpose bonds continued to produce solid results.
With general tax revenues still sluggish, investors flocked to securities
with relatively stable revenue streams, and


3



municipal bonds backed by essential services -- such as water, sewer and
electric utilities -- benefited from this demand. Land-development bonds also
fared well thanks to low mortgage rates and higher real estate prices.

[Table at top left-hand side of page entitled "Top five industry groups2."
The first listing is General obligation 14%, the second is Authority 11%,
the third is Health 8%, the fourth is Transportation 7% and the fifth is
Water & sewer 7%.]

LONG-TERM BONDS BOOST PERFORMANCE

The strong returns of the portfolio's long-term bonds also enhanced Fund
performance. Bonds with longer maturities experience greater price
fluctuations when interest rates move up or down, and the general decline
in yields during the six-month period produced healthy price gains among
longer-term municipal bonds.

The portfolio had a sizable position in long-term bonds for most of 2003,
but we have been gradually reducing this position in recent months. For
example, the Fund's exposure to bonds maturing in 25 years or more declined
from 25% of the portfolio at the beginning of the period to 21% by the end
of February. With bond yields hovering near historic lows, we believe the
next major interest rate move is likely to be higher, so we are reducing
the portfolio's volatility by selling some of its longer-term securities.

[Pie chart at middle of page with heading "Portfolio diversification As a
percentage of net assets on 2-29-04." The chart is divided into three
sections (from top to left): Revenue bonds 84%, General obligation bonds
14% and Short-term investments and other 2%.]

FINDING VALUE IN GENERAL OBLIGATION BONDS

California's general obligation (GO) bonds generally lagged the performance
of other bonds, largely because of the state's recent credit rating
downgrade. However, we selectively added California state GO bonds to the
portfolio at a time when prices were especially attractive, and we were
rewarded when they increased in value. We sold most of the portfolio's
state GOs at a


4



tidy profit during a seasonal period of strong demand for
municipal bonds in early 2004.

is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
Longer-term bonds followed by an up arrow with the phrase "Benefited the
most from falling rates." The second listing is Tobacco-related bonds
followed by an up arrow with the phrase "Litigation issues were favorably
resolved." The third listing is Essential-services bonds followed by an up
arrow with the phrase "Stable, dedicated revenue stream."]

OUTLOOK

The economy's recent strength suggests that interest rates will eventually
rise, but the timing of an uptick in rates is less clear. The lack of job
creation, combined with other potential pitfalls such as rising oil prices,
could weaken the pace of economic recovery. As a result, we wouldn't be
surprised to see bond yields remain in a fairly narrow range for much of
2004.

"...we wouldn't be surprised
 to see bond yields remain
 in a fairly narrow range for
 much of 2004."

We believe the deterioration in California's credit quality has bottomed,
and we expect to see higher tax revenues and improving fiscal conditions
going forward. The state's fiscal challenges are far from over, but we view
the state's upcoming bond issuance -- including $15 billion in recovery
bonds and $12 billion in school construction bonds -- as a last best
opportunity to pick up California GO bonds at bargain prices.

In the portfolio, we intend to continue following our current strategy of
reducing the portfolio's overall interest-rate sensitivity and price
volatility. This will allow us to focus on what we believe is our
competitive advantage: individual security selection.

end of the Fund's period discussed in this report. The managers' statements

Performance figures assume all distributions are reinvested. Returns with
maximum sales charge reflect a sales charge on Class A shares of 4.50% and
Class C shares of 1%, and the applicable contingent deferred sales charge
(CDSC) on Class B and Class C shares. The Class B shares' CDSC declines
annually between years 1-6 according to the following schedule: 5, 4, 3, 3,
2, 1%. No sales charge will be assessed after the sixth year. Class C
shares held for less than one year are subject to a 1% CDSC. The return and
principal value of an investment in the Fund will fluctuate, so that
shares, when redeemed, may be worth more or less than the original cost.

The returns reflect past results and should not be considered indicative of
future performance. The performance table above and the chart on the next
page do not reflect the deduction of taxes that a shareholder would pay on
fund distributions or the redemption of fund shares. 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 Fund's performance results reflect any applicable expense reductions,
without which the expenses would increase and results would have been less
favorable. These reductions can be terminated in the future. See the
prospectus for details.

2 As required, effective 9-1-01 the Fund has adopted the provisions of the
  AICPA Audit and Accounting Guide for Investment Companies, as revised,
  relating to the amortization of premiums and accretion of discounts on debt
  securities. The effect of this change on per share amounts for the year
  ended 8-31-02 was to increase net investment income per share by $0.01,
  increase net realized and unrealized losses per share by $0.01 and, had the
  Fund not made these changes to amortization and accretion, the ratio of net
  investment income to average net assets would have been 4.88%, 4.07% and
  4.03%, for Class A, Class B and Class C shares, respectively. Per share
  ratios and supplemental data for periods prior to 9-1-01 have not been
  restated to reflect this change in presentation.

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 Fund seeks a high level of current income,
consistent with the preservation of capital, that is exempt from federal and
California personal income taxes. Since the Fund invests primarily in
California issuers, the Fund may be affected by political, economic or
regulatory developments in the state of California.

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 as 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 that bears distribution
and service expenses under the 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, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group, LLC,
may participate in a joint repurchase agreement transaction. Aggregate cash
balances are invested in one or more large 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.

Discount and premium on securities

The Fund accretes discount and amortizes premium from par


24



value on securities from either the date of issue or the
date of purchase over the life of the security.

Class allocations

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

Expenses

The majority of expenses are directly identifiable to an individual fund.
Expenses that 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.

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 permits borrowings of up
to $250 million, collectively. Interest is charged to each fund based on
its borrowing. In addition, a commitment fee is charged to each fund based
on the average daily unused portion of the line of credit, and is allocated
among the participating funds. The Fund had no borrowing activity under the
line of credit during the period ended February 29, 2004.

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 that is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $5,304,234 of a capital loss
carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent that such carryforward is
used by the Fund, no capital gain distributions will be made. The loss
carryforward expires as follows: August 31, 2004 -- $2,378,578, August 31,
2005 -- $7,774, August 31, 2006 -- $679,515, August 31, 2008 -- $968,588
and August 31, 2011 -- $1,269,779.

Interest and distributions

Interest income on investment securities is recorded on the accrual basis.

The Fund records distributions to shareholders from net investment income
and net realized gains on the ex-dividend date. The Fund's net investment
income is declared daily as dividends to shareholders of record as of the
close of business on the preceding day, and distributed monthly.
Distributions paid by the Fund with respect to each class of shares are
calculated in the same manner, at the same time and are in the same amount,
except for the effect of expenses that may be applied differently to each
class.

Such distributions, on a tax basis, are determined in conformity with income
tax regulations, which may differ from accounting principles generally
accepted in the United States of America. Distributions in excess of tax
basis earnings and profits, if any, are reported in the Fund's financial
statements as a return of capital.

Use of estimates

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

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to
the Adviser 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 and (b)
0.50% of the Fund's average daily net asset value in excess of
$500,000,000.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"),
a wholly owned subsidiary of the Adviser. 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, to reimburse JH Funds for the
services it provides as distributor of shares of the Fund. Accordingly, the
Fund makes monthly payments to JH Funds at an annual rate not to exceed
0.15% of Class A average daily net asset value and 1.00% of Class B and
Class C average daily net asset value. A maximum of 0.25% of such payments
may be service fees, as defined by the Conduct Rules of the National
Association of Securities Dealers. Under the Conduct Rules, curtailment of
a portion of the Fund's 12b-1 payments could occur under certain
circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended February 29, 2004, JH Funds received net up-front sales
charges of $117,280 with regard to sales of Class A shares. Of this amount,
$15,443 was retained and used for printing prospectuses, advertising, sales
literature and other purposes, $88,861 was paid as sales commissions to
unrelated broker-dealers and $12,976 was paid as sales commissions to sales
personnel of Signator Investors, Inc. ("Signator Investors"), a related
broker-dealer. The Adviser's indirect parent, John Hancock Life Insurance
Company ("JHLICo"), is the indirect sole shareholder of Signator Investors.
During the period ended February 29, 2004, JH Funds received net up-front
sales charges of $2,925 with regard to sales of Class C shares, which was
paid as sales commissions to unrelated broker-dealers.

Class B shares that are redeemed within six years of purchase are 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.
Class C shares that are redeemed within one year of purchase are 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 CDSCs 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 and Class C
shares. During the period ended February 29, 2004, CDSCs received by JH
Funds amounted to $56,638 for Class B shares and $1,733 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. The Fund pays a monthly
transfer agent fee at an annual rate of 0.01% of the Fund's average daily
net asset value, plus a fee based on the number of shareholder accounts and
reimbursement for certain out-of-pocket expenses, aggregated and allocated
to each class on the basis of its relative net asset value.

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 approximately 0.03% of the average daily net asset
value of the Fund. The Fund also paid the Adviser the amount of $468 for
certain publishing services, included in the printing fees.

Ms. Maureen Ford Goldfarb is a director and/or officer of


26



the Adviser and/or its affiliates, as well as Trustee 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 investments, as well as any
unrealized gains or losses. The Deferred Compensation Plan investments had no
impact on the operations of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the
period ended February 29, 2004, aggregated $40,495,626 and $48,991,814,
respectively.

The cost of investments owned on February 29, 2004, including short-term
investments, for federal income tax purposes, was $340,953,078. Gross
unrealized appreciation and depreciation of investments aggregated
$39,111,769 and $1,049,175, respectively, resulting in net unrealized
appreciation of $38,062,594. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable primarily
to amortization of premiums and accretion of discounts on debt securities.
