The performance of the Fund's four share classes varies because each has
different expenses. The Fund's total return figures assume the reinvestment of
all distributions but do not reflect the deduction of any applicable sales
charges. Such costs would lower performance. Past performance is no guarantee of
future results. See Performance Summary for standardized performance
information.

MARKET CONDITIONS

During the first six months of 2004, an array of positive indicators confirmed
the strength of the U.S. economic recovery. Not only was solid growth recorded
but the long-awaited improvement in employment became apparent. Unfortunately,
the strengthening economy also brought the specter of higher inflation. While a
year ago the Federal Reserve was actively prepared to fight price deflation, by
early this spring it had begun to signal a change in policy. The fixed-income
markets reacted to these events by sending interest rates higher. Finally, on
June 30, 2004, the Federal Reserve Board ended the easiest monetary policy in
decades by raising its short-term borrowing rate for the first time in four
years.

The changing outlook also affected the municipal market. By the end of June,
yields on intermediate and long-term tax-exempt bonds had increased to their
highest levels in nearly a year. Bond prices, which move in the opposite
direction of interest rates, fell accordingly. Rising interest rates have
historically resulted in reduced issuance of municipal securities. In keeping
with this pattern, the year-to-date volume of $188 billion was 9 percent below
last year's record level. Much of the decline can be attributed to June, when
issuance fell 29 percent. Of the major states, only California had an increase
in volume.

On the demand side, higher yields attracted retail investors who began to
reinvest upcoming coupon payments and maturities. The ratio of municipal yields
to Treasury yields -- a gauge of the relative performance of the two
markets -- also remained stable. The ratio of 30-year insured municipals to
Treasuries averaged 96 percent for the quarter, and the 10-year ratio averaged
89 percent of Treasuries. This relationship continued to attract buying activity
by nontraditional investors including hedge funds and arbitrage accounts.

The California municipal market entered the period in the doldrums, with the
state's general debt carrying the lowest investment-grade rating of any state
from Moody's and Standard & Poor's. The market took a turn for the better with
the widely publicized election of Arnold Schwarzenegger as governor, then
improved further as the new governor successfully implemented new policy
initiatives aimed at easing the state's fiscal woes. Key among these measures
was a $7.9 billion economic recovery package, part of a total of $11 billion in
deficit financing intended to raise further capital to cover the state's budget
shortfalls. Yield spreads between California and national issues declined
measurably for all maturities.

PERFORMANCE ANALYSIS

Morgan Stanley California Tax-Free Income Fund underperformed the Lehman
Brothers Municipal Bond Index, and its Class A, B and C shares underperformed
the Lipper California Municipal Debt Funds Index for the six-month period ending
June 30, 2004. However, the Fund's Class D shares did slightly outperform the
Lipper Index. In the rising-interest-rate environment, the Fund benefited by
maintaining a shorter than benchmark portfolio duration* to reduce volatility.
In part, the lower duration reflected a mix of holdings that included
higher-coupon bonds priced to various call dates. These bonds are generally
considered defensive in nature. New purchases were focused in the 15- to 20-year
range. In keeping with our long-term strategy, we managed the Fund with a bias
toward high-quality investments. As indicated, nearly 75 percent of the bonds in
the portfolio at the close of the review period were rated either AA or AAA. The
Fund was well diversified, with 63 individual credits in 14 municipal sectors.

* A measure of the sensitivity of a bond's price to changes in interest rates,
  expressed in years. Each year of duration represents an expected 1 percent
  change in the price of a bond for every 1 percent change in interest rates.
  The longer a bond's duration, the greater the effect of interest-rate
  movements on its price. Typically, funds with shorter durations perform better
  in rising-interest-rate environments, while funds with longer durations
  perform better when rates decline.

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley California Tax-Free Income Fund (the "Fund") is registered under
the Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide a high level of current income which is exempt from federal and
California income tax, consistent with the preservation of capital. The Fund was
organized as a Massachusetts business trust on April 9, 1984 and commenced
operations on July 11, 1984. On July 28, 1997, the Fund converted to a multiple
class share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year, six
years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; and (3) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined

16


Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) continued

by the identified cost method. Discounts are accreted and premiums are amortized
over the life of the respective securities. Interest income is accrued daily.

C. Multiple Class Allocations -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

D. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Fund is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract. Such receipts or payments known as
variation margin are recorded by the Fund as unrealized gains and losses. Upon
closing of the contract, the Fund realizes a gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.

E. Federal Income Tax Policy -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.

F. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

G. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. Investment Management Agreement

Pursuant to an Investment Management Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Manager") the Fund pays the Investment Manager a
management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.55% to the portion of daily net assets not exceeding $500
million; 0.525% to the portion of daily net assets exceeding $500 million but
not exceeding $750 million; 0.50% to the portion of daily net assets exceeding
$750 million but not exceeding $1 billion;

                                                                              17


Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) continued

0.475% to the portion of daily net assets exceeding $1 billion but not exceeding
$1.25 billion; and 0.45% to the portion of daily net assets in excess of $1.25
billion.

3. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan
provides that the Fund will pay the Distributor a fee which is accrued daily and
paid monthly at the following annual rates: (i) Class A -- up to 0.25% of the
average daily net assets of Class A; (ii) Class B -- up to 0.75% of the lesser
of: (a) the average daily aggregate gross sales of the Class B shares since the
inception of the Fund (not including reinvestment of dividend or capital gain
distributions) less the average daily aggregate net asset value of the Class B
shares redeemed since the Fund's inception upon which a contingent deferred
sales charge has been imposed or waived; or (b) the average daily net assets of
Class B; and (iii) Class C -- up to 0.75% of the average daily net assets of
Class C.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that there were no excess expenses as of
June 30, 2004.

For the period January 1, 2004 through April 30, 2004, the Distributor rebated a
portion of the distribution fees paid by the Fund on Class B shares in the
amount of $1,379,167.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.75% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the six months ended June 30, 2004, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.15% and 0.75%,
respectively.

The Distributor has informed the Fund that for the six months ended June 30,
2004, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and

18


Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) continued

Class C shares of $184,602 and $1,212, respectively and received $28,811 in
front-end sales charges from sales of the Fund's Class A shares. The respective
shareholders pay such charges which are not an expense of the Fund.

4. Security Transactions and Transactions with Affiliates

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended June 30, 2004 aggregated
$47,928,620 and $107,201,042, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At June 30, 2004, the Fund had transfer agent fees
and expenses payable of approximately $4,200.

The Fund has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation.
Aggregate pension costs for the six months ended June 30, 2004 included in
Trustees' fees and expenses in the Statement of Operations amounted to $3,691.
At June 30, 2004, the Fund had an accrued pension liability of $59,663 which is
included in accrued expenses in the Statement of Assets and Liabilities. On
December 2, 2003, the Trustees voted to close the plan to new participants and
eliminate the future benefits growth due to increases to compensation after July
31, 2003.

Effective April 1, 2004, the Fund began an unfunded Deferred Compensation Plan
(the "Compensation Plan") which allows each independent Trustee to defer payment
of all, or a portion, of the fees he receives for serving on the Board of
Trustees. Each eligible Trustee generally may elect to have the deferred amounts
credited with a return equal to the total return on one or more of the Morgan
Stanley funds that are offered as investment options under the Compensation
Plan. Appreciation/depreciation and distributions received from these
investments are recorded with an offsetting increase/decrease in the deferred
compensation obligation and do not affect the net asset value of the Fund.

5. Expense Offset

The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Fund.

                                                                              19


Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) continued

6. Risks Relating to Certain Financial Instruments

The Fund may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.

To hedge against adverse interest rate changes, the Fund may invest in financial
futures contracts or municipal bond index futures contracts ("futures
contracts").

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the value of the underlying securities. Risks may also
arise upon entering into these contracts from the potential inability of the
counterparties to meet the terms of their contracts.

7. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

As of December 31, 2003, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and book amortization of
discounts on debt securities.

8. Legal Matters

The Investment Manager, certain affiliates of the Investment Manager, certain
officers of such affiliates and certain investment companies advised by the
Investment Manager or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of the Morgan Stanley funds. The consolidated
amended complaint generally alleges that defendants, including the Fund,
violated their statutory disclosure obligations and fiduciary duties by failing
properly to disclose (i) that the Investment Manager and certain affiliates of
the Investment Manager allegedly offered economic incentives to brokers and
others to recommend the funds advised by the Investment Manager or its
affiliates to investors rather than funds managed by other companies, and (ii)
that the funds advised by the Investment Manager or its affiliates, including
the Fund, allegedly paid excessive commissions to brokers in return for their
efforts to

20


Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) continued

recommend these funds to investors. The complaint seeks, among other things,
unspecified compensatory damages, rescissionary damages, fees and costs. The
defendants have moved to dismiss the action and intend to otherwise vigorously
defend it. While the Fund believes that it has meritorious defenses, the
ultimate outcome of this matter is not presently determinable at this early
stage of the litigation, and no provision has been made in the Fund's financial
statements for the effect, if any, of this matter.

9. Shares of Beneficial Interest

Transactions in shares of beneficial interest were as follows:
