Dear Shareholder

March 22, 2000

Recap of Events - Economic activity in the United States continues to surpass
expectations. An improving global economic outlook continued to reduce demand
for U.S. government debt over the last six months, pushing U.S. bond prices
lower and yields significantly higher.

The booming stock market, however, did heighten inflationary concerns during our
fiscal period. The Federal Reserve responded by raising interest rates five
times between June 30, 1999 and March 21, 2000. As of this writing the federal
funds target rate on overnight loans between banks stands at 6.00%, its highest
level in more than four years. The Federal Reserve's actions have been directed
at slowing the economy and pre-empting inflation before it takes root.

Municipal bonds weathered the turbulent fixed-income arena somewhat better than
U.S Treasuries during the past municipal year. Municipal bond yields steadily
increased throughout this period, but municipal bond prices fluctuated less than
Treasuries (Source: Bloomberg). When bond yields rise, their prices generally
fall.

As of February 29, 2000 the 30-year U.S. Treasury bond yield stood at 6.16%,
while 30-year U.S. AAA-rated general obligation municipal bonds closed at 5.90%
(Source: Bloomberg). For investors in the 28% tax bracket, a 5.90% tax-free
yield would be equivalent to an 8.19% yield on a taxable investment, surpassing
that of the 30-year Treasury.

Delaware Tax-Free Pennsylvania, New Jersey and Ohio Funds - As yields rose,
municipal bonds generally lost value for the twelve months ending February 29,
2000. Our tax-free municipal bond funds in Pennsylvania, New Jersey and Ohio
were no exception - all three Funds finished the year lower than where they
started.

A longer-than-average duration was the primary reason Delaware's Tax-Free New
Jersey and Ohio Funds had such a difficult time preserving capital. In
Pennsylvania, credit concerns in the health care industry reduced the value of
some Delaware Tax-Free Pennsylvania Fund holdings in that sector. Please see the
Portfolio Management Review for a detailed discussion of each Fund's
performance.

Market Outlook - Although stocks have recently captured more investor attention
and a larger share of their assets, we believe fixed-income investments play an
important role in well-balanced portfolios. Looking forward, we believe bonds
may remain in the shadow of stocks as long as economic growth continues in 2000.
However, tax-exempt bonds, which your Fund holds, offer several advantages that
make them an attractive long-term option for many investors including:

o Current income that is free from federal, and in the case of the Delaware
Tax-Free Pennsylvania, New Jersey and Ohio Funds, free of certain state and
local taxes as well.

o A wide range of choices to meet your investment objectives with regard to
investment quality, maturity, type of bond and geographical location.

We realize that the past 12 months have been a difficult period for fixed-income
investors. We applaud you for remaining committed to your investment plan and
thank you for your continued confidence in Delaware Investments.

Sincerely,


/s/ Wayne A. Stork                        /s/ David K. Downes

"WHILE HIGHER INTEREST

RATES WERE PUSHING

MUNICIPAL BOND PRICES

LOWER, REDUCED

SUPPLY HELPED RELIEVE

ANOTHER POTENTIAL

SOURCE OF DOWNWARD

PRICE PRESSURE."

The Funds' Results
Over the past twelve months, the market environment for fixed-income investments
has been extremely difficult. The U.S. economy continued to expand rapidly
without any appreciable inflation, drawing substantial investor attention to
stocks of large, growing companies and technology companies. Shortly after the
start of your Fund's fiscal year in March 1999, equity markets as measured by
the Dow Jones Industrial Average and the S&P 500 reached all-time highs.

Global economies were growing as well, convincing investors that the worst of
the 1998 Asian recession was over and reducing the appeal of U.S. government
debt. As countries emerged from their slowdown, demand for some U.S. goods and
services began to pick up, creating concerns over inflation and higher interest
rates.

While higher interest rates were pushing municipal bond prices lower, reduced
supply helped relieve another potential source of downward price pressure. More
than $225 billion in new municipal bonds were issued during calendar 1999. This
was substantially less than the near record $285 billion sold during 1998.
Still, demand for municipal bonds was not nearly sufficient to meet the
available supply. The states of Pennsylvania, New Jersey and Ohio were three of
the nation's more aggressive bond issuers in 1999, ranking 6th, 7th and 9th
respectively in bond sales (Source: The Bond Buyer).

As the end of calendar year 1999 approached, investors seemed to be concerned
about the potential tax burden created by the appreciation of their equity
investments. In some cases, these investors attempted to offset equity gains by
redeeming shares of their municipal bond funds at a loss. According to the
Investment Company Institute, municipal bond mutual funds experienced $12.0
billion in redemptions during the fourth quarter of 1999. Redemptions remained
relatively heavy during January and February of 2000. This magnified the
imbalance between supply and demand and further reduced the value of most
municipal bonds.

Delaware Tax-Free Pennsylvania Fund
Against this challenging economic backdrop for municipal bond funds, Delaware
Tax-Free Pennsylvania Fund had a disappointing total return of -5.18% (Class A
shares at net asset value with distributions reinvested) for the 12 months ended
February 29, 2000. We were somewhat less successful than our peers in the Lipper
Pennsylvania Municipal Bond Fund Average at preserving capital during the
period.

A key reason for the underperformance was the length of the Fund's duration.
Duration, which measures a bond's sensitivity to fluctuating interest rates, is
a key factor in municipal bond performance. During the first six months of your
Fund's fiscal year, we modestly extended our duration by purchasing longer term
bonds, which generally offered higher yields.

                                                                               3

[GRAPHIC OMITTED]

Delaware Tax-Free Pennsylvania Fund (continued)
The Fund's duration continued to extend throughout the second half of the year,
largely due to higher interest rates. Usually the duration of a callable bond is
based on the first date that it is likely to be redeemed by the issuer. When
interest rates go down, issuers often redeem their bonds prior to maturity and
issue new bonds at lower rates to save money. Issuers normally pay a premium
price to call a bond prior to maturing. When rates increase, however, there is
less chance that bonds will be redeemed prior to maturity. This means that their
effective duration increases, getting closer to the stated maturity of the bond,
which lowers the bond's value.

Health care bonds were another area of concern for the Fund. As of
February 29, 2000, more than 18% of Delaware Tax-Free Pennsylvania Fund's assets
were invested in health care bonds. This sector has historically provided an
attractive yield, however, since the widely publicized bankruptcy of Allegheny
Health Systems in 1998, investors have been less interested in hospital bonds.
During the past year, we avoided potential credit concerns by selling bonds
issued by the University of Pennsylvania and Temple University hospitals. We
plan to continue to selectively reduce your Fund's health care allocation in the
coming year.

Delaware Tax-Free New Jersey Fund
Over the last 12 months we struggled to preserve principal as rising interest
rates reduced the value of many of Delaware Tax-Free New Jersey Fund holdings. A
longer-than-average duration was the primary obstacle to more competitive
performance.

Since the Fund's inception in 1997, we have generally maintained an extended
duration to build a portfolio that delivers an attractive yield for our
investors. To accomplish this we invested significantly in longer term bonds,
which offered higher income potential in return for taking the chance that
rising interest rates would reduce the bond's price. While this strategy allowed
us to provide a

competitive yield, rising interest rates over the past year reduced the appeal
of long-term debt. This lowered the value of our long-term bonds and made it
difficult for us to shorten our duration.

Although the actual inflation rate has remained relatively benign, persistent
inflation concerns and rising interest rates during the Fund's fiscal year
resulted in a disappointing total return of -7.68% (Class A shares at net asset
value with distributions reinvested). This was less than the return of other
municipal bond funds in the Lipper New Jersey Municipal Bond Fund Average.

Nationally, new municipal bond issues fell significantly in 1999. New Jersey,
however, continued to offer bonds at a brisk pace. In fact, new municipal bond
sales fell only 1.7% in calendar 1999 compared to a national decline of more
than 21% (Source: The Bond Buyer). This heavy new supply during a period of
lackluster investor demand also contributed to your Fund's weak return.

New Jersey, like many other states, is enjoying a period of growth and economic
prosperity. High-tech industries, in particular, have taken a firm root in the
northern part of the Garden State, which is now being called a new "Silicon
Valley." This points to continued economic strength, which we believe will help
support the income paying ability of New Jersey municipalities in the future.

Delaware Tax-Free Ohio Fund (continued)
Due to their long duration, a large percentage of the bonds in Delaware Tax-Free
Ohio Fund are currently priced at a "discount," well below their par value. When
bonds are bought for less than their original issue price the investor must pay
taxes on the appreciation between their purchase price and their par value when
the bond matures. Investors were reluctant to assume this potential tax burden,
which reduced demand for some of our bonds, contributing to the Fund's
disappointing annual return.

Ohio was the first state to impose an income tax on residents and remains a
relatively high-tax state. In 1999, Ohio ranked 14th nationally in terms of
state and local taxes as a percentage of income (Source: The Tax Foundation).
Despite our recent results, we believe this points to strong demand for
tax-exempt income in the state.

Outlook
Rising interest rates during your Fund's fiscal year seem to have had little
impact on the robust U.S. economy, which shows no indication of slowing. The
Federal Reserve has demonstrated a commitment to keeping inflation in check,
which suggests that more interest rate hikes are possible.

However, despite continued U.S. economic growth, inflation has remained
surprisingly benign. Labor productivity gains appear to be the key that allows
the economy to expand without significant inflation. In calendar 1999, according
to the U.S. Department of Labor, U.S. employers continued to find ways to get
more work done without increasing their labor costs. Despite a tight job market,
labor costs in 1999 declined in both the third and fourth quarters, largely due
to productivity gains.

The positive news for municipal bond investors is that we are now finding many
opportunities to invest in attractive municipal bonds at compelling prices.
Credit quality remains very solid in the municipal bond markets. Given their
current value, relatively high credit quality and tax-exempt income, we think
municipal bonds offer an attractive long-term investment that can help diversify
portfolios that are heavily allocated to equities.

Notes to Financial Statements

February 29, 2000
- --------------------------------------------------------------------------------
Delaware Group State Tax-Free Income Trust (the "Trust") is registered
as a non-diversified open-end investment company under the Investment Company
Act of 1940, as amended. The Trust is organized as a Pennsylvania trust and
offers three series: the Delaware Tax-Free Pennsylvania Fund, the Delaware
Tax-Free New Jersey Fund, and the Delaware Tax-Free Ohio Fund (each referred to
as a "Fund" or collectively as the "Funds"). The A Class carries a front-end
sales charge of 3.75%. The B Class carries a back-end deferred sales charge and
the C Class carries a level load deferred sales charge.

The Delaware Tax-Free Pennsylvania Fund seeks as high a level of current
interest income exempt from federal income tax and Pennsylvania State income tax
as is consistent with preservation of principal. The Delaware Tax-Free New
Jersey Fund seeks as high a level of current interest income exempt from federal
income tax and New Jersey state income tax as is consistent with preservation of
principal. The Delaware Tax-Free Ohio Fund seeks as high a level of current
interest income exempt from federal income tax and Ohio state income tax as is
consistent with preservation of principal.

1. Significant Accounting Policies
The following accounting policies are in accordance with accounting principles
generally accepted in the United States and are consistently followed by the
Trust:

Security Valuation - Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Money market instruments having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Trustees.

Federal Income Taxes - Each Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from generally
accepted accounting principles.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
each Fund on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

Use of Estimates - The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

Other - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Interest income is recorded on the accrual basis. Original issue discounts and
market premiums are amortized to interest income over the lives of the
respective securities. Each Fund declares dividends from net investment income
daily and pays such dividends monthly. Capital gains, if any, are distributed
annually.

<PAGE>


Certain expenses of the Trust are paid through "soft dollar" arrangements with
brokers. These transactions are done subject to best price and execution. Each
Fund may receive earnings credits from its custodian when positive cash balances
are maintained, which are used to offset custody fees. The expenses paid under
the above arrangements are included in their respective expense captions on the
Statement of Operations with the corresponding expense offset shown as "expenses
paid indirectly". The amount of these expenses and credits for the year ended
February 29, 2000 are as follows:

                                              Delaware     Delaware    Delaware
                                              Tax-Free     Tax-Free    Tax-Free

                                            ------------  ----------   ---------

Earnings Credits ......................        184,161       5,367       2,196

2. Investment Management and Other Transactions with Affiliates
In accordance with the terms of the Investment Management Agreement, each Fund
pays Delaware Management Company ("DMC"), the Investment Manager of the Funds,
an annual fee, based on its net assets. The management fee rates changed
effective April 1, 1999.

Following are the new management fees as a percentage of average daily net
assets:

                                            ------------  ----------   ---------

In excess of $2.5 billion .............         0.425%       0.425%      0.425%

Prior to April 1, 1999, Delaware Tax-Free Pennsylvania Fund paid DMC an annual
fee at the rate of 0.60% on the first $500 million of average daily net assets
of the Fund, 0.575% on the next $250 million and 0.55% on the average daily net
assets over $750 million, less all amounts paid to the trustees, and the

the rate of 0.55% on the first $500 million of average daily net assets, 0.525%
on the next $500 million and 0.50% on the average daily net assets over $1
billion.

                                                                              25

5. Lines of Credit
Effective October 8, 1999, the Funds, along with certain other funds in the
Delaware Investments Family of Funds (the "Participants"), participate in a
$683,500,000 revolving line of credit facility to be used for temporary or
emergency purposes as an additional source of liquidity to fund redemptions of
investor shares. The Participants are charged an annual commitment fee, which is
allocated across the Participants on the basis of each Funds' allocation of the
entire facility. The Participants may borrow up to a maximum of one third of
their net assets under the agreement. Prior to October 8, 1999, the Delaware
Tax-Free Pennsylvania, New Jersey, and Ohio Funds had committed lines of credit
of $29,100,000, $100,000 and $100,000, respectively. The Funds had no amounts
outstanding at February 29, 2000 or at any time during the fiscal year.

<PAGE>


6. Market and Credit Risk
The Funds concentrate their investments in securities issued by municipalities.
The value of these investments may be adversely affected by new legislation
within the states, regional or local economic conditions, and differing levels
of supply and demand for municipal bonds. Many municipalities insure repayment
for their obligations. Although bond insurance reduces the risk of loss due to
default by an issuer, such bonds remain subject to the risk that the market may
fluctuate for other reasons and there is no assurance that the insurance company
will meet its obligations. These securities have been identified in the
Statement of Net Assets.

7. Tax Information (Unaudited)
The information set forth below is for each Fund's fiscal year as required
by federal laws. Shareholders, however, must report distributions on a calendar
year basis for income tax purposes, which may include distributions for portions
of two fiscal years of a fund. Accordingly, the information needed by
shareholders for income tax purposes will be sent to them in early 2000. Please
consult your tax advisor for proper treatment of this information. For the
fiscal year ended February 29, 2000, each Fund designates as long-term capital
gains and ordinary income distributions paid during the year as follows:

                                                        (A)            (B)

Report of Independent Auditors
- --------------------------------------------------------------------------------
To the Shareholders and Board of Trustees
Delaware Group State Tax-Free Income Trust

We have audited the accompanying statements of net assets of Delaware Group
State Tax-Free Income Trust (the "Trust") (comprised of Delaware Tax-Free
Pennsylvania Fund, Delaware Tax-Free New Jersey Fund and Delaware Tax-Free Ohio
Fund) and the statements of assets and liabilities of Delaware Tax-Free New
Jersey Fund and Delaware Tax-Free Ohio Fund as of February 29, 2000, and the
related statements of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of February 29, 2000, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective funds constituting the Delaware Group State Tax-Free Income
Trust at February 29, 2000, the results of their operations for the year then
ended, the changes in their net assets for each of the two years in the period
then ended, and their financial highlights for each of the periods indicated
therein, in conformity with accounting principles generally accepted in the
United States.
