THE PERFORMANCE OF THE FUND'S FOUR SHARE CLASSES VARIES BECAUSE EACH HAS
DIFFERENT EXPENSES. THE FUND'S TOTAL RETURNS ASSUME THE REINVESTMENT OF ALL
DISTRIBUTIONS BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES.
SUCH COSTS WOULD LOWER PERFORMANCE. SEE PERFORMANCE SUMMARY FOR STANDARDIZED
PERFORMANCE AND BENCHMARK INFORMATION.

BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12B-1 PLAN THAN DID
CLASS A SHARES FOR THE FISCAL PERIOD ENDED JUNE 30, 2005, THE TOTAL OPERATING
EXPENSE RATIO FOR CLASS B SHARES WAS LOWER AND, AS A RESULT, THE PERFORMANCE OF
CLASS B SHARES WAS HIGHER THAN THAT OF THE CLASS A SHARES. THERE CAN BE NO
ASSURANCE THAT THIS WILL CONTINUE TO OCCUR IN THE FUTURE AS THE MAXIMUM FEES
PAYABLE BY CLASS B SHARES UNDER THE 12B-1 PLAN ARE HIGHER THAN THOSE PAYABLE BY
CLASS A SHARES.

MARKET CONDITIONS

Consumer spending and business investment helped the U.S. economy expand at a
solid pace during the six-month period ending June 30, 2005. However, the
direction of some economic indicators, including job growth, remained uneven and
caused uncertainty about the strength of the economy. Consequently, interest
rates fluctuated, moving higher when reports were strong and lower when data was
weaker than anticipated. The first quarter of 2005 saw generally rising interest
rates. By April, however, the themes of low inflation and slow growth were again
prevalent and interest rates fell through the end of June.

Throughout the period, the Federal Open Market Committee (the "Fed") reaffirmed
its pledge to raise the federal funds target rate at a "measured" pace.
Continuing the policy shift begun in June 2004, the Fed increased the federal
funds target rate four times during the first half of 2005, in 25 basis point
increments. These moves brought the federal funds target rate to 3.25 percent at
the end of the reporting period.

Against this setting, the municipal bond market followed the taxable market and
the yields of long-term tax-exempt issues increased in the first quarter. The
course changed in the second quarter, as the market rallied and yields fell to
near-record lows. Persistent investor demand for income sustained the momentum
of this long-term bond rally. Meanwhile, the yields of shorter maturity
bonds -- which were more directly influenced by the Fed's actions -- rose. As a
result, the municipal yield curve continued to flatten and the yield spread (or
differential between one-year rates and 30-year rates) narrowed. Investors'
quest for yield favored lower-quality investment grade bonds over high-grade
issues, keeping quality spreads tight.

Led by a surge in refundings, municipal issuers continued to rush to the market
in the first six months of 2005. New issue volume increased by nine percent to
$206 billion, a record for the first six months of a calendar year. Refundings
increased to 35 percent of total issuance, up from 24 percent in 2004. Bonds
backed by insurance dominated issuance and increased their market penetration to
60 percent. California issuers represented 13 percent of the new underwriting
volume in 2005.

 2


On the demand side, the municipal-to-Treasury yield ratio, which gauges relative
performance between the two markets, was attractive for tax-exempt bonds. As a
result, institutional investors (such as arbitrage accounts and hedge funds)
that normally focus on taxable bond sectors supported municipals by "crossing
over" to purchase bonds. However, retail investors were deterred by the absolute
level of rates and largely remained on the sidelines for most of the period.

California's economy demonstrated sustained improvement. Residential real-estate
markets showed continued strength and unemployment edged downward. On the fiscal
front, strong personal and corporate income tax growth helped stabilize the
credit outlook.

PERFORMANCE ANALYSIS

Morgan Stanley California Tax-Free Income Fund Class A and Class C shares
underperformed the Lehman Brothers Municipal Bond Index and its Class B and D
shares outperformed this Index for the six-month period ending June 30, 2005,
assuming no deduction of applicable sales charges. The Fund underperformed the
Lipper California Municipal Debt Funds Index for the same period.

During the period, the Fund maintained a conservative strategy in anticipation
of continued Fed tightening and higher interest rates. As a result, the Fund's
overall duration* (a measure of interest rate sensitivity) was managed to be
lower than its benchmark. The Fund's option adjusted duration was 6.8 years at
the end of June. This positioning helped performance early in the period when
rates rose into April, but hindered total returns when rates declined later in
the period. Lower rates also led municipal issuers to refinance outstanding
debt. The prerefunding of several of the Fund's holdings had a positive impact
on performance. The Fund continued to maintain a high average credit quality,
with 90 percent of assets in bonds rated A or higher at the close of the
reporting period. As credit spreads tightened, this high grade orientation had
an adverse impact on performance. The Fund's net assets of $611 million were
well diversified across 71 credits in 13 long-term 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.

There is no guarantee that any sectors mentioned will continue to perform well
or that securities in such sectors will be held by the Fund in the future.

Performance data quoted represents past performance, which is no guarantee of
future results and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
www.morganstanley.com or speak with your financial advisor. Investment returns
and principal value will fluctuate and fund shares, when redeemed, may be worth
more or 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.

*   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 contingent deferred sales charge for Class C is 1% for shares
    redeemed within one year of purchase.

++  Class D has no sales charge.

(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 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, which
     is adjusted for capital gains distributions and income dividends, is
     unmanaged and should not be considered an investment. There are currently
     30 funds represented in this 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.

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments and redemption fees;
and (2) ongoing costs, including management fees; distribution and service
(12b-1) fees; and other Fund expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 01/01/05 - 06/30/05.

ACTUAL EXPENSES


The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES


The second line of the table below provides information about hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) and redemption fees. Therefore, the second line of the table is
useful in comparing ongoing costs, and will not help you determine the relative
total cost of owning different funds. In addition, if these transactional costs
were included, your costs would have been higher.

INVESTMENT ADVISORY AGREEMENT APPROVAL

NATURE, EXTENT AND QUALITY OF SERVICES


The Board reviewed and considered the nature and extent of the investment
advisory services provided by the Investment Adviser under the Advisory
Agreement, including portfolio management, investment research and fixed income
securities trading. The Board also reviewed and considered the nature and extent
of the non-advisory, administrative services provided by the Fund's
Administrator under the Administration Agreement, including accounting,
clerical, bookkeeping, compliance, business management and planning, and the
provision of supplies, office space and utilities. (The Investment Adviser and
the Administrator together are referred to as the "Adviser" and the Advisory and
Administration Agreements together are referred to as the "Management
Agreement.") The Board also compared the nature of the services provided by the
Adviser with similar services provided by non-affiliated advisers as reported to
the Board by Lipper Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers,
the senior administrative managers and other key personnel of the Adviser who
provide the administrative and investment advisory services to the Fund. The
Board determined that the Adviser's portfolio managers and key personnel are
well qualified by education and/or training and experience to perform the
services in an efficient and professional manner. The Board concluded that the
nature and extent of the advisory and administrative services provided were
necessary and appropriate for the conduct of the business and investment
activities of the Fund. The Board also concluded that the overall quality of the
advisory and administrative services was satisfactory.

PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


The Board reviewed the Fund's performance for the one-, three- and five-year
periods ended November 30, 2004, as shown in reports provided by Lipper (the
"Lipper Reports"), compared to the performance of comparable funds selected by
Lipper (the "performance peer group"), and noted that the Fund's performance was
lower than, but close to, its performance peer group average for all three
periods. The Board concluded that the Fund's performance was satisfactory.

FEES RELATIVE TO OTHER FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT
STRATEGIES


The Board reviewed the advisory and administrative fees (together, the
"management fee") paid by the Fund under the Management Agreement. The Board
noted that the rate was comparable to the management fee rates charged by the
Adviser to any other funds it manages with investment strategies comparable to
those of the Fund.

 10


FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


The Board reviewed the management fee rate and total expense ratio of the Fund.
The Board noted that: (i) the Fund's management fee rate was higher than the
average management fee rate for funds, selected by Lipper (the "expense peer
group"), managed by other advisers, with investment strategies comparable to
those of the Fund, as shown in the Lipper Report for this Fund; and (ii) the
Fund's total expense ratio was also higher than the average total expense ratio
of the funds included in the Fund's expense peer group. The Board and the
Adviser discussed the Fund's management fee and total expense ratio and the
Adviser agreed to impose a cap of 0.60% on the Fund's total expenses, excluding
brokerage and 12b-1 fees, which would have the effect of reducing the management
fee and/or other expenses of the Fund. The Board concluded that with the
proposed cap the Fund's management fee and total expense ratio would be
competitive with those its expense peer group.

BREAKPOINTS AND ECONOMIES OF SCALE


The Board reviewed the structure of the Fund's management fee schedule under the
Management Agreement and noted that it includes breakpoints. The Board also
reviewed the level of the Fund's management fee and noted that the fee, as a
percentage of the Fund's net assets, would decrease as net assets increase
because the management fee includes breakpoints. The Board concluded that the
Fund's management fee would reflect economies of scale as assets increase.

PROFITABILITY OF ADVISER AND AFFILIATES


The Board considered and reviewed information concerning the costs incurred and
profits realized by the Adviser and its affiliates during the last two years
from their relationship with the Fund and the Morgan Stanley Fund Complex and
reviewed with the Controller of the Adviser the cost allocation methodology used
to determine the Adviser's profitability. Based on their review of the
information they received, the Board concluded that the profits earned by the
Adviser and its affiliates were not excessive in light of the advisory,
administrative and other services provided to the Fund.

FALL-OUT BENEFITS


The Board considered so-called "fall-out benefits" derived by the Adviser and
its affiliates from their relationship with the Fund and the Morgan Stanley Fund
Complex, such as "float" benefits derived from handling of checks for purchases
and redemptions of Fund shares through a broker-dealer affiliate of the Adviser.
The Board also considered that a broker-dealer affiliate of the Adviser receives
from the Fund 12b-1 fees for distribution and shareholder services. The Board
concluded that the float benefits were relatively small and that the 12b-1 fees
were competitive with those of other broker-dealer affiliates of investment
advisers.

                                                                              11


SOFT DOLLAR BENEFITS


The Board considered whether the Adviser realizes any benefits from commissions
paid to brokers who execute securities transactions for the Fund ("soft
dollars"). The Board noted that the Fund invests only in fixed income
securities, which do not generate soft dollars.

ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS


The Board considered whether the Adviser is financially sound and has the
resources necessary to perform its obligations under the Management Agreement.
The Board noted that the Adviser's operations remain profitable, although
increased expenses in recent years have reduced the Adviser's profitability. The
Board concluded that the Adviser has the financial resources necessary to
fulfill its obligations under the Management Agreement.

HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER


The Board also reviewed and considered the historical relationship between the
Fund and the Adviser, including the organizational structure of the Adviser, the
policies and procedures formulated and adopted by the Adviser for managing the
Fund's operations and the Board's confidence in the competence and integrity of
the senior managers and key personnel of the Adviser. The Board concluded that
it is beneficial for the Fund to continue its relationship with the Adviser.

OTHER FACTORS AND CURRENT TRENDS


The Board considered the controls and procedures adopted and implemented by the
Adviser and monitored by the Fund's Chief Compliance Officer and concluded that
the conduct of business by the Adviser indicates a good faith effort on its part
to adhere to high ethical standards in the conduct of the Fund's business.

GENERAL CONCLUSION


After considering and weighing all of the above factors, the Board concluded it
would be in the best interest of the Fund and its shareholders to approve
renewal of the Management Agreement for another year.

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (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 eighteen
months, 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

                                                                              21

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (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 Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Adviser") the Fund pays the Investment Adviser an
advisory 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: 0.47% to the portion of the daily net assets not exceeding $500
million; 0.445% to the portion of the daily net assets exceeding $500 million
but not exceeding $750 million; 0.42% to the portion of the daily net assets
exceeding $750 million but not

 22

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (UNAUDITED) continued

exceeding $1 billion; 0.395% to the portion of the daily net assets exceeding $1
billion but not exceeding $1.25 billion; and 0.37% to the portion of the daily
net assets in excess of $1.25 billion.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays an administration fee, accrued daily and payable monthly, by applying the
annual rate of 0.08% to the fund's daily net assets.

Effective June 1, 2005, the Investment Adviser has agreed to cap the Fund's
operating expenses (except for brokerage and 12b-1 fees) by assuming the Fund's
"other expenses" and/or waiving the Fund's advisory fees, and the Administrator
has agreed to waive the Fund's administrative fees, to the extent such operating
expenses exceed 0.60% of the average daily net assets of the Fund on an
annualized basis. These voluntary assumptions/waivers may be discontinued at any
time.

3. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Adviser and Administrator. 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 expenses as of June 30,
2005.

For the six months ended June 30, 2005, the distribution fee was accrued for
Class B shares at the annual rate of 0.06%. At June 30, 2005, included in the
Statement of Assets and Liabilities, is a receivable from affiliate of $87,656
which represents payments by the Distributor.

                                                                              23

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (UNAUDITED) continued

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, 2005, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.24% and 0.74%,
respectively.

The Distributor has informed the Fund that for the six months ended June 30,
2005, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $112,312 and $925, respectively
and received $76,683 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, 2005 aggregated
$74,885,900 and $82,883,953, respectively. Included in the aforementioned
transactions is a purchase of $5,416,400 and a sale of $5,343,350 with another
Morgan Stanley fund including a net realized gain of $443,891.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and
Distributor, is the Fund's transfer agent.

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, 2005 included in
Trustees' fees and expenses in the Statement of Operations amounted to $3,662.
At June 30, 2005, the Fund had an accrued pension liability of $61,151 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.

The Fund has 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

 24

NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (UNAUDITED) continued

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.

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, 2004, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and book amortization of
discounts on debt securities.

                                                                              25

9. Legal Matters

The Investment Adviser, certain affiliates of the Investment Adviser, certain
officers of such affiliates and certain investment companies advised by the
Investment Adviser or its affiliates, including the Fund, are named as
defendants in a consolidated class action. 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 Adviser
and certain affiliates of the Investment Adviser allegedly offered economic
incentives to brokers and others to recommend the funds advised by the
Investment Adviser or its

 26

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2005 (UNAUDITED) continued

affiliates to investors rather than funds managed by other companies, and (ii)
that the funds advised by the Investment Adviser or its affiliates, including
the Fund, allegedly paid excessive commissions to brokers in return for their
efforts to 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. On March 10, 2005, Plaintiffs sought leave to supplement
their complaint to assert claims on behalf of other investors. While the Fund
and Adviser believe that each 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.

                                                                              27
