LETTER TO THE SHAREHOLDERS December 31, 1998 New York, New York 10048
DEAR SHAREHOLDER:
We are pleased to present the annual report on the operations of Morgan Stanley
Dean Witter Tax-Exempt Securities Trust for the fiscal year ended December 31,
1998.
Since our last report six months ago, global financial turmoil, including the
Russian currency crisis, continued to affect the securities markets. The
resulting flight-to-quality bond rally pushed U.S. Treasury bond yields to
30-year lows. Municipal bond yields declined but lagged the downward trend of
Treasury yields.
The deflationary impact of the international financial crisis began to temper
U.S. economic growth prior to the summer's tumultuous market activity. Lower
commodity prices, cheaper imports and improved productivity offset the
potential inflationary impact of strong domestic employment. With inflation
held in check, the Federal Reserve Board provided liquidity to the markets by
lowering short-term interest rates. Between the end of September and the middle
of November the Federal Reserve Open Market Committee cut the federal funds
rate 75 basis points from 5.50 percent to 4.75 percent in three separate moves.

MUNICIPAL MARKET CONDITIONS
At the end of December the long-term insured municipal bond index yield stood
at 5.05 percent. This Index declined only 10 basis points from 5.15 percent
over the last 12 months. In contrast, the 30-year U.S. Treasury yield fell 80
basis points during the same period.
As municipals lagged the rally in Treasuries, the ratio of municipal yields to
Treasury yields rose sharply to 99 percent. A rising ratio means that the
attractiveness of municipals relative to Treasuries has improved. The rise in
this ratio is similar to the jump witnessed in 1986 when a radical legislative
tax-reform proposal threatened the favorable tax advantage of municipal bonds.
The overall decline in interest rates led to a substantial increase in new
money municipal financing and stimulated the refunding of older, high cost
debt. Total underwriting of $284 billion for 1998 approached the record set in
1993. Half the underwriting volume was enhanced with bond insurance. Refundings
represented 29 percent of total new issuance.
PERFORMANCE
For the 12-month period ended December 31, 1998 Morgan Stanley Dean Witter
Tax-Exempt Securities Trust Class A, B, C and D shares produced total returns
of 5.86 percent, 5.47 percent, 5.36 percent and 6.11 percent, respectively.
Performance of the Fund's shares varies, because of differing expenses. Over
the same period, the Lehman Brothers Municipal Bond Index posted a total return
of 6.48 percent, while the Lipper Analytical Services, Inc. General Municipal
Debt Funds Index registered a total return of 5.64 percent. The Fund's net
assets exceeded $1.1 billion.
PORTFOLIO STRUCTURE
The Fund remained fully invested in long-term municipal bonds during the year.
Investments were diversified among 13 long-term sectors and 134 credits. As
illustrated in the accompanying chart of bond calls, weighted average call
protection was 7 years.
At the time of issuance, municipal bonds generally have 10 years of protection
from the municipality's option to call bonds for redemption. Interest rates
have declined since the Fund's inception and we anticipate that most municipal
issuers will use their optional call provisions to refinance portfolio holdings
at lower yields. In fact, the bonds in the refunded category have been
refinanced and the call dates announced.
The average maturity of the portfolio was 17 years. Average duration (a measure
of sensitivity to interest rate changes) was 7 years. High grade credit quality
was maintained with over 80 percent of long-term holdings rated double or
triple "A."

LOOKING AHEAD
Global economic conditions seem likely to keep inflationary pressures under
control and have contributed to lower interest rates. The fixed income markets
appear concerned about the risk of reflation as countries seek to stimulate
economic growth. However, the ability of the Fed to maintain stability by
responding with appropriate monetary policy is encouraging. With the municipal
relationship to Treasuries more favorable than it has been in the last 10 years,
the outlook for municipal bonds is positive.
We appreciate your ongoing support of Morgan Stanley Dean Witter Tax-Exempt
Securities Trust and look forward to continuing to serve your investment needs.
Very truly yours,
/s/ Charles A. Fiumefreddo

PRIOR TO JULY 28, 1997 THE FUND OFFERED ONLY ONE CLASS OF SHARES. BECAUSE THE
DISTRIBUTION ARRANGEMENTS FOR CLASS A MOST CLOSELY RESEMBLED THE DISTRIBUTION
ARRANGEMENT APPLICABLE PRIOR TO THE IMPLEMENTATION OF MULTIPLE CLASSES (I.E.,
CLASS A IS SOLD WITH A FRONT-END SALES CHARGE), HISTORICAL PERFORMANCE
INFORMATION HAS BEEN RESTATED TO REFLECT THE ACTUAL MAXIMUM SALES CHARGE
APPLICABLE TO CLASS A (I.E., 4.25%) AS COMPARED TO THE 4.00% SALES CHARGE IN
EFFECT PRIOR TO JULY 28, 1997. IN ADDITION, CLASS A SHARES ARE NOW SUBJECT TO AN
ONGOING 12B-1 FEE WHICH IS REFLECTED IN THE RESTATED PERFORMANCE FOR THAT CLASS.
BECAUSE ALL SHARES OF THE FUND HELD PRIOR TO JULY 28, 1997 WERE DESIGNATED CLASS
D SHARES, THE FUND'S HISTORICAL PERFORMANCE HAS BEEN RESTATED TO REFLECT THE
ABSENCE OF ANY SALES CHARGE.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS December 31, 1998
1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Dean Witter Tax-Exempt Securities Trust (the "Fund"), formerly
Dean Witter Tax-Exempt Securities Trust, is registered under the Investment
Company Act of 1940, as amended, 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 income tax, consistent with the
preservation of capital. The Fund was incorporated in Maryland in 1979,
commenced operations on March 27, 1980 and reorganized as a Massachusetts
business trust on April 30, 1987. On July 28, 1997, the Fund commenced offering
three additional classes of shares, with the then current shares designated as
Class D shares.
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 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.
The following is a summary of significant accounting policies:
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized 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
Fund's 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. 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.
17
<PAGE>
MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS December 31, 1998, continued
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 by the identified cost method.
The Fund amortizes premiums and accretes discounts 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. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.
E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends
and distributions to its shareholders on the record 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.
2. INVESTMENT MANAGEMENT AGREEMENT
Pursuant to an Investment Management Agreement with Morgan Stanley Dean Witter
Advisors Inc. (the "Investment Manager"), formerly Dean Witter Intercapital
Inc., 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: 0.50% to the portion of
daily net assets not exceeding $500 million; 0.425% to the portion of daily net
assets exceeding $500 million but not exceeding $750 million; 0.375% to the
portion of daily net assets exceeding $750 million but not exceeding $1
billion; 0.35% to the portion of daily net assets exceeding $1 billion but not
exceeding $1.25 billion; and 0.325% to the portion of daily net assets
exceeding $1.25 billion.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS December 31, 1998, continued
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services,
heat, light, power and other utilities provided to the Fund.
3. PLAN OF DISTRIBUTION
Shares of the Fund are distributed by Morgan Stanley Dean Witter 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 -- 0.60% of
the average daily net assets of Class B; and (iii) Class C -- up to 0.70% of
the average daily net assets of Class C. In the case of Class A shares, amounts
paid under the Plan are paid to the Distributor for services provided. In the
case of Class B and Class C shares, amounts paid under the Plan are paid to the
Distributor for (1) services provided and the expenses borne by it and others
in the distribution of the shares of these Classes, including the payment of
commissions for sales of these Classes and incentive compensation to, and
expenses of, the Morgan Stanley Dean Witter Financial Advisors and others who
engage in or support distribution of the shares or who service shareholder
accounts, including overhead and telephone expenses; (2) printing and
distribution of prospectuses and reports used in connection with the offering
of these shares to other than current shareholders; and (3) preparation,
printing and distribution of sales literature and advertising materials. In
addition, the Distributor may utilize fees paid pursuant to the Plan, in the
case of Class B shares, to compensate Dean Witter Reynolds Inc. ("DWR"), an
affiliate of the Investment Manager and Distributor, and other selected
broker-dealers for their opportunity costs in advancing such amounts, which
compensation would be in the form of a carrying charge on any unreimbursed
expenses.
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
19
<PAGE>
MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS December 31, 1998, continued
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts, including
carrying charges, totaled $3,972,552 at December 31, 1998.
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 0.70% 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 Dean Witter Financial Advisors or other
selected broker-dealer representatives may be reimbursed in the subsequent
calendar year. For the year ended December 31, 1998, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.24% and
0.70%, respectively.
The Distributor has informed the Fund that for the year ended December 31,
1998, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B and Class C shares of $119,895 and $6,087, respectively and
received $168,708 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 year ended December 31, 1998
aggregated $177,148,205 and $232,551,397, respectively.
Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager
and Distributor, is the Fund's transfer agent. At December 31, 1998, the Fund
had transfer agent fees and expenses payable of approximately $18,900.
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 year ended December 31, 1998
included in Trustees' fees and expenses in the Statement of Operations amounted
to $5,976. At December 31, 1998, the Fund had an accrued pension liability of
$51,129 which is included in accrued expenses in the Statement of Assets and
Liabilities.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter
Tax-Exempt Securities Trust (the "Fund"), formerly Dean Witter Tax-Exempt
Securities Trust, at December 31, 1998, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
presented, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
December 31, 1998 by correspondence with the custodian, provide a reasonable
basis for the opinion expressed above.
