Dear Shareholder:

DURING FISCAL 1999, GLOBAL ECONOMIC
turmoil drove foreign and domestic investors to the safety and liquidity of U.S.
Treasuries. Increased demand bolstered Treasury prices and pushed yields lower.
Municipal bond yields declined also, but to a much lesser extent. This narrowed
the gap that normally exists between yields on tax-free municipal bonds and
taxable Treasuries.

   By October, at the height of the Treasury market's price rally, longer term
municipal bonds offered as much as 98% of the income potential of comparable
Treasuries. Although this fell to about 89% by the end of our reporting period,
historically municipal bonds have yielded 83% of Treasuries (Source: Municipal
Market Data). Therefore, we believe municipal bonds are still undervalued
relative to Treasuries and still offer attractive income potential.

   For the 12 months ended February 28, 1999, total returns for Tax-Free
Pennsylvania Fund, Tax-Free New Jersey Fund and Tax-Free Ohio Fund (for Class A
shares at net asset value) outpaced the average of comparable funds in their
respective states, as shown in the table below. However, we fell short of the
broad-based Lehman Brothers Municipal Bond Index.

   In fiscal 1999, we increased the average duration (sensitivity to interest
rates) on all three funds in order to take advantage of higher yields available
on longer term tax-exempt bonds and to benefit from a possible recovery in bond
prices if interest rates rose. This had a positive impact on the Funds'
performance.

     Supply of high-grade municipal bonds was unusually strong over the past 12
months. Over $285 billion in new bonds

was available in 1998, the second largest annual supply on record. Pennsylvania
was the nation's 4th largest issuer, up 33% over the previous year, while New
Jersey and Ohio ranked 9th and 10th, respectively, according to The Bond Buyer,
a municipal bond trade publication.

   A surge in refunding activity - up 42% since 1997 - contributed to the high
volume of new municipal bonds in 1998. Like homeowners who take advantage of low
interest rates to refinance their mortgage, municipalities can refinance older
bonds that were issued when interest rates were higher. Many states, including
Pennsylvania, capitalized on lower interest rates to reduce existing debt
payments.

   On the pages that follow, portfolio managers Patrick Coyne and Mitchell
Conery review developments in the municipal bond market during fiscal 1999, as
well as the performance and current portfolio positioning of Tax-Free
Pennsylvania, New Jersey and Ohio Funds. They also share their outlook for
fiscal 2000.

   We appreciate your investment, and we look forward to helping you reach your
financial goals well into the new millennium.

Portfolio Managers' Review

Patrick P. Coyne and Mitchell L. Conery
Vice Presidents/Senior Portfolio Managers
March 12, 1999


MUNICIPAL BOND YIELDS RIVALED TREASURIES
Last spring as we began fiscal 1999, the U.S. economy had entered its eighth
consecutive year of expansion, the stock market was posting solid gains, and
fixed-income securities offered attractive income amid a low inflation
environment.

   But over the summer and early fall, economic and currency problems erupted in
Russia and along the Pacific Rim, and U.S. corporate earnings slowed. Investors
sought refuge in U.S. Treasury bonds. As bond prices rose, the yield on the
30-year U.S. Treasury hit an historic low of 4.72% in October. As a result,
municipal bond yields gained ground on Treasury yields.

   By late fall, 30-year AAA (the highest quality rating) general obligation
municipal bonds had a yield of 4.82%, approximately 98% of the yield available
from comparable maturity Treasuries. This was a compelling value given that the
interest on municipal bonds is exempt from federal income tax.

   As we concluded fiscal 1999, the yield on the 30-year U.S. Treasury had moved
up to 5.58%. (Source: Bloomberg Business News) Though this widened the yield gap
between municipal bonds and Treasuries, municipal bond yields were still closer
to Treasuries than they normally are.

MUNICIPAL CREDIT
QUALITY IMPROVED
Other reasons municipal bonds remain an attractive investment, in our opinion,
are the financial strength of state and local governments and the improving
credit quality of their debt issues. In 1998, credit quality upgrades exceeded
downgrades by a seven-to-one margin, according to Standard & Poor's.

- --------------------------------------------------------------------------------
Higher percentages indicate that municipal bonds offer attractive income levels
compared to U.S. Treasuries. Historically, long-term municipal bonds have
yielded about 83% of what comparable Treasuries yield. Based on this measure, we
believe long-term municipals offer the best value currently.

   During the year, the difference between yields of bonds with a quality rating
of AAA (the highest rating available) and those with lower ratings narrowed.
Because of this, we felt that it was more prudent to purchase higher quality
bonds because we weren't gaining sufficient extra income in return for the extra
risk related to lower grade bonds. The table below reflects our focus on higher
credit quality.

STRATEGIC POSITIONING
Tax-Free Pennsylvania Fund
Late in fiscal 1999, we began to lengthen the average duration of Tax-Free
Pennsylvania Fund. Our goal was to capture the higher income potential of
long-term bonds. As of February 28, the Fund's average duration (sensitivity to
interest rates) was 7.2 years, up 1.1 from 6.1 years at the end of last fiscal
year.

   Our longer durations and our focus on bonds rated BBB or better contributed
positively to the Fund's performance. As of fiscal year-end, over 86% of
Tax-Free Pennsylvania Fund was allocated to investment-grade bonds; 60% was
invested in securities rated AAA. Our emphasis on very high quality bonds also
helps reduce overall credit risk in the portfolio.

   Bonds that were pre-refunded made up the largest portion of the Fund's sector
allocation. With interest rates at their lowest levels in years, many
municipalities refinanced their existing debt to reduce their long-term
obligations. Many of our pre-refunded holdings have high coupon rates (the
stated rate of interest on the bond) and have added nicely to the Fund's
dividend.

   Hospital revenue bonds accounted for 20.38% of the portfolio's net assets as
of February 28, 1999. We remain cautiously optimistic about the hospital sector.
After last year's highly publicized bankruptcy of Allegheny Health Systems, many
Pennsylvania hospitals have begun to trim costs and manage their facilities more
efficiently. This is an encouraging development, but one that has not yet spread
to all hospitals. Extensive credit analysis is essential to distinguish between
the good and bad apples.

   We did not own Allegheny at the time it filed for bankruptcy; our credit
research led us to sell it well ahead of its troubles.

We believe this in-depth credit research has enabled us to pinpoint hospitals in
solid financial condition.

TAX-FREE NEW JERSEY FUND
In her 1999 State of the State Address this past January, New Jersey Governor
Christine Todd Whitman called the health of the nation's Garden State "vibrant
and vigorous." A strong growing economy and low unemployment have contributed to
a positive outlook for the state and strong credit ratings for its 
municipalities.

   As of February 28, Tax-Free New Jersey Fund held nearly 95% of its total net
assets in investment-grade municipal bonds, with more than 77% in AAA bonds.
This offered us additional credit protection during the year, and helped us
lower our overall credit risk.

   In order to capture higher income, we extended the Fund's average duration.
This was a significant driving force in the Fund's performance.

   For the 12-month period, Tax-Free New Jersey Fund delivered a total return of
5.93%, (for class A shares at net asset value) outpacing the average of its
peers. The Fund's largest holding was a revenue bond issued by the New Jersey
Economic Development Authority to fund the United Water New Jersey Project. This
project has helped municipalities to save on wastewater management costs by
aligning public water utilities with private service providers.

   Because New Jersey residents bear a higher overall tax burden than half the
country - New Jersey ranked 22nd among all states in 1998 for state and local
taxes+ - investor demand for New Jersey tax-exempt bonds is strong. However,
there has not been a tremendous amount of supply, which can occasionally make
our job of investing portfolio assets more challenging.

TAX-FREE OHIO FUND
Like New Jersey, Ohio is also considered a "high tax" state. It ranked 24th
among all states in 1998 for state and local taxes.+ The demand for bonds by
Ohio investors looking to reduce their tax liability has

outnumbered the supply of municipal bonds available for investing, a trend
similar to what we've experienced in New Jersey.

   Revenue bonds issued to finance projects in transportation, airports and
higher education made up another one-third of the portfolio. AMT revenue bonds -
bonds issued for industrial development and that have interest subject to the
federal alternative minimum tax - accounted for 3.4% of the portfolio's asset
mix.

   Tax-Free Ohio Fund benefited from additional income earned as a result of a
longer duration. We slightly lengthened the average duration during this period
from 8.4 years to 8.7 years. This was a longer duration than the average of its
peers and helped boost the Fund's relative performance in fiscal 1999.

   The Fund's top holding is Air Freight. This express mail service represented
12.8% of net assets. As intermediate-term interest rates have declined, Air
Freight's 6.05% coupon rate provided attractive income for the Fund. We also
benefited from a pre-refunded revenue bond issued by the Ohio State Turnpike
Commission which offered a higher than average coupon compared to revenue bonds
issued by other states' turnpike commissions.

MARKET OUTLOOK
   As we expected, 1999's supply of new municipal bonds has slowed from last
year's levels primarily because most municipalities have already refinanced
existing debt at lower interest rates.

   We expect to continue our strategy of increasing each Fund's income potential
by extending average duration, consistent with the Fund's objective. Although
municipal bonds still appear relatively inexpensive when compared to Treasuries,
we believe the real "value opportunities" are at the far end of the maturity
spectrum where interest rates are higher.

   To help manage the risks of investing in longer term bonds, we continue to
focus on securities with investment-grade quality ratings. With state and local
governments' credit quality improving, we believe municipal bonds remain a sound
choice for investors seeking to increase their income potential without
increasing their tax liability.

Returns reflect reinvestment of distributions and any applicable sales charges
as noted below. Return and share value will fluctuate so that shares, when
redeemed, may be worth more or less than the original cost. Class B and Class C
results excluding sales charge assumes either that contingent sales charges did
not apply or the investment was not redeemed. Past performance is not a
guarantee of future results. Returns reflect voluntary expense limitations and
would have been lower without the limitations.

Class A shares have a 3.75% maximum front-end sales charge and a 12b-1 fee. (For
Tax-Free Pennsylvania Fund, a 12b-1 fee was effective on 6/1/92). 

Class B shares do not carry a front-end sales charge, but are subject to a 1%
annual distribution and service fee. They are subject to a deferred sales charge
of up to 4% if redeemed before the end of the sixth year.

Class C shares have a 1% annual distribution and service fee. If redeemed within
12 months, a 1% contingent deferred sales charge applies.

DELAWARE GROUP STATE TAX-FREE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS
FEBRUARY 28, 1999
- --------------------------------------------------------------------------------
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 Tax-Free Pennsylvania Fund, the Tax-Free New Jersey Fund, and
the 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 Tax-Free Pennsylvania Fund seeks as high a level of current income exempt
from federal income tax and Pennsylvania state income tax as is consistent with
preservation of principal. The Tax-Free New Jersey Fund seeks as high a level of
current income exempt from federal income tax and New Jersey state income tax as
is consistent with preservation of principal. The Tax-Free Ohio Fund seeks as
high a level of current 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 generally accepted
accounting principles 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
generally accepted accounting principles 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. The
custodian bank of the Trust has agreed to waive its custodial fees when a fund
maintains a prescribed amount of cash on deposit in certain non-interest bearing
accounts. Such fee waivers are included in the Statement of Operations as
expenses paid indirectly. 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.

Certain expenses of the Trust are paid through "soft dollar" arrangements with
brokers. The amount of these expenses is less than 0.01% of the Fund's average
daily net assets.
<PAGE>

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, an annual fee
which is calculated daily at the rate of 0.60% of 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
directors, for the Tax-Free Pennsylvania Fund, and 0.55% of 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, for the Tax-Free New Jersey
Fund and the Tax-Free Ohio Fund.

DMC has elected to waive its fees and reimburse the Tax-Free New Jersey Fund and
the Tax-Free Ohio Fund to the extent that annual operating expenses exclusive of
distribution expenses exceed 0.25% of average daily net assets through July 31,
1999. On February 28, 1999, the Tax-Free Pennsylvania Fund had a liability for
investment management fees and other expenses payable to DMC of $74,636.

The Trust has engaged Delaware Service Company, Inc. (DSC), an affiliate of DMC,
to provide dividend disbursing, transfer agent and accounting services. Each
Fund pays DSC a monthly fee based on the number of shareholder accounts,
shareholder transactions and average net assets, subject to certain minimums. On
February 28, 1999, the Tax-Free Pennsylvania Fund had a liability payable to DSC
of $31,798.

Pursuant to the Distribution Agreement, each Fund pays Delaware Distributors,
L.P. (DDLP), the Distributor and an affiliate of DMC, an annual fee not to
exceed 0.30% of the average daily net assets of the A Class for the Tax-Free
Pennsylvania Fund and 0.25% of the average daily net assets of the Tax-Free New
Jersey Fund and the Tax-Free Ohio Fund A Classes and 1.00% of the average daily
net assets of the B and C Class for all three Funds.

For the year ended February 28, 1999, DDLP earned $100,877, $1,731 and $383 for
commissions on sales of the A class shares for the Tax-Free Pennsylvania Fund,
the Tax-Free New Jersey Fund and the Tax-Free Ohio Fund, respectively.

Certain officers of DMC, DSC and DDLP are officers, trustees and/or employees of
the Trust. These officers, trustees and employees are paid no compensation by
the Trust.

3. Investments

investment securities other than temporary cash investments as follows:

5. Lines of Credit   
The Trust has a committed line of credit for $29.1 million for the Tax-Free
Pennsylvania Fund, $100,000 for the Tax-Free New Jersey Fund and $100,000 for
the Tax-Free Ohio Fund. No amount was outstanding at February 28, 1999, or at
any time during the fiscal year.

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.

DELAWARE GROUP STATE TAX-FREE INCOME TRUST
REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
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 Tax-Free Pennsylvania
Fund, Tax-Free New Jersey Fund, and Tax-Free Ohio Fund) and the statement of
assets and liabilities of Tax-Free New Jersey Fund as of February 28, 1999, and
the related statements of operations for the year then ended, and the statements
of changes in net assets and 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 generally accepted auditing
standards. 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 28, 1999, 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 28, 1999, the results of their operations for the year then
ended, and the changes in their net assets and their financial highlights for
each of the periods indicated therein, in conformity with generally accepted
accounting principles.
