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

The six-month period ended June 30, 2003, was a favorable time for the
fixed-income markets. The U.S. economy continued to recover but at a slow pace.
This led to investor concern that reaching the economy's full growth potential
would be delayed. The Federal Reserve Board shared this concern and cut the
federal funds rate in June. The reduction in the short-term borrowing rate was
felt across the yield curve and drove yields down to levels not seen in decades.

Several factors caused the rally in municipal bonds to lag Treasuries. First,
states and municipalities sold a record amount of debt to meet cash flow needs
and refinance higher cost issues. Municipal yields also adjusted to federal tax
legislation, which included acceleration of scheduled tax bracket reductions and
a lower tax on dividends. Finally, the yields of some credits were affected by
potential budget deficits. These factors caused the municipal market to
establish yield levels that attracted interest from crossover investors such as
insurance companies and hedge funds seeking value relative to taxable bonds.
Institutional crossover investors remained cautious on California exposure
because of the state's budget deficit and potential recall election. However,
retail investors needing state exemption absorbed record new-issue supply.

PERFORMANCE ANALYSIS

With rates at historically low levels, the market appeared to be anticipating a
prolonged, weak economic recovery. This assessment seemed unduly pessimistic in
light of monetary and fiscal policies seeking to stimulate growth. Since this
stimulus should eventually result in stronger economic growth and higher
interest rates, we maintained the Fund's shorter-than-average duration. This
conservative portfolio structure underperformed the Lehman Brothers Municipal
Bond Index during the period.

We sought to preserve shareholder value by maintaining a high-grade portfolio
with over 75 percent of long-term holdings rated either double- or -triple "A".
The portfolio is structured with a greater-than-average weighting of premium
coupon bonds. These bonds are somewhat more defensive than current-coupon (par)
bonds in a rising-rate environment. The Fund benefited by offering securities
with less favorable structure for sale to take advantage of demand for bonds
with California tax-exemption.

Purchases at the sector level focused on high-grade revenue bonds backed by
electric, transportation and water and sewer projects. The Fund has maintained a
cautious stance toward the general obligation sector because of a number of
issuers under budgetary stress face potential credit rating downgrades. The Fund
also benefited by our decision to avoid tobacco bonds.

Past performance is not predictive of future returns. Investment return and
principal value will fluctuate. When you sell fund shares, they may be worth
less than their original cost. The table does not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. Performance for Class A, Class B, Class C, and Class D shares will vary
due to differences in sales charges and expenses.

Notes on Performance

(1)  The Lehman Brothers Municipal Bond Index tracks the performance of
     municipal bonds rated at least Baa or BBB by Moody's Investors Service,
     Inc. or Standard & Poor's Corporation, respectively and with maturities of
     2 years or greater. Indexes are unmanaged and their returns do not include
     any expenses, sales charges or fees. Such costs would lower performance. It
     is not possible to invest directly in an index.

(2)  The Lipper California Municipal Debt Funds Index is an equally weighted
     performance index of the largest qualifying funds (based on net assets) in
     the Lipper California Municipal Debt Funds classification. The Index is
     adjusted for capital gains distributions and income dividends. There are
     currently 30 funds represented in this Index. Indexes are unmanaged and
     their returns do not include any sales charges or fees. Such costs would
     lower performance. It is not possible to invest directly in an index.

(3)  Figure shown assumes reinvestment of all distributions and does not reflect
     the deduction of any sales charges.

(4)  Figure shown assumes reinvestment of all distributions and the deduction of
     the maximum applicable sales charge. See the Fund's current prospectus for
     complete details on fees and sales charges.

*    The maximum front-end sales charge for Class A is 4.25%.

**   The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%.
     The CDSC declines to 0% after six years.

+    The maximum CDSC for Class C is 1% for shares redeemed within one year of
     purchase.

++   Class D has no sales charge.

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2003 (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 bid side of the market each day. 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; (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

 14

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2003 (UNAUDITED) continued

determined 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. 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 financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in capital.

                                                                              15

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2003 (UNAUDITED) continued

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; 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 -- 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, 2003.

 16

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2003 (UNAUDITED) continued

For the six months ended June 30, 2003, the Distributor rebated a portion of the
distribution fees paid by the Fund on Class B shares in the amount of
$1,600,405.

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, 2003, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.12% and 0.75%,
respectively.

The Distributor has informed the Fund that for the six months ended June 30,
2003, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $205,115 and $1,806,
respectively and received $64,245 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, 2003 aggregated
$24,833,460 and $58,008,184, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At June 30, 2003, the Fund had transfer agent fees
and expenses payable of approximately $3,600.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all 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 years of service and compensation during the last five years
of service. Aggregate pension costs for the six months ended June 30, 2003
included in Trustees' fees and expenses in the Statement of Operations amounted
to $3,589. At June 30, 2003, the Fund had an accrued pension liability of
$58,189 which is included in accrued expenses in the Statement of Assets and
Liabilities.

5. Federal Income Tax Status

At December 31, 2002, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and book amortization of
discounts on debt securities.

                                                                              17

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2003 (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.

At June 30, 2003, the Fund held positions in residual interest bonds having a
total value of $15,332,520, which represents 2.0% of the Fund's net assets.

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.

At June 30, 2003, the Fund had no outstanding futures contracts.
