DISCLOSURE                       For the Period March 1, 2004 to August 31, 2004
  OF FUND EXPENSES

As a shareholder of a fund, you incur two types of costs: (1) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (2) ongoing costs,
including management fees; distribution and/or 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 March 1, 2004 to August 31, 2004.

ACTUAL EXPENSES
The first section of the table shown, "Actual Fund Return," provides information
about actual account values and actual expenses. You may use the information in
this section, 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 section 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 section of the table shown, "Hypothetical 5% Return," provides
information about hypothetical account values and 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 costs 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), redemption fees, or exchange fees. Therefore, the second
section of the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have been
higher. The Fund's actual expenses shown in the table reflect fee waivers in
effect. The expenses shown in the table assume reinvestment of all dividends and
distributions.

NOTES                                        DELAWARE TAX-FREE PENNSYLVANIA FUND
  TO FINANCIAL STATEMENTS                    August 31, 2004 (Unaudited)


Delaware Group State Tax-Free Income Trust (the "Trust") is organized as a
Delaware statutory trust and offers one series: Delaware Tax-Free Pennsylvania
Fund (the "Fund"). The Trust is an open-end investment company. The Fund is
considered non-diversified under the Investment Company Act of 1940, as amended
and offers Class A, Class B, and Class C shares. Class A shares are sold with a
front-end sales charge of up to 4.50%. Class B shares are sold with a contingent
deferred sales charge that declines from 4% to zero depending upon the period of
time the shares are held. Class B shares will automatically convert to Class A
shares on a quarterly basis approximately 8 years after purchase. Class C shares
are sold with a contingent deferred sales charge of 1%, if redeemed during the
first 12 months.

The investment objective of Delaware Tax-Free Pennsylvania Fund is to seek a
high level of current interest income exempt from federal income tax and certain
Pennsylvania state and local taxes, consistent with the preservation of capital.

1. SIGNIFICANT ACCOUNTING POLICIES
The following accounting policies are in accordance with U.S. generally accepted
accounting principles and are consistently followed by the Fund.

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. Short-term debt securities 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 under the direction of the Fund's Board of
Trustees.

Federal Income Taxes - The Fund intends to continue to qualify for federal
income tax purposes 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.

Class Accounting - Investment income and common expenses are allocated to the
classes of the Fund on the basis of "settled shares" of each class in relation
to the net assets of the Fund. Realized and unrealized gain (loss) on
investments are allocated to the various classes of the 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
U.S. 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.
Management fees and other expenses are paid monthly. 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. Discounts and premiums are amortized to interest
income over the lives of the respective securities.

The Fund declares dividends daily from net investment income and pays such
dividends monthly and declares and pays distributions from net realized gain on
investments, if any, annually. The Fund receives earnings credits from its
custodian when positive cash balances are maintained, which are used to offset
custody fees. The earnings credits for the six months ended August 31, 2004 were
approximately $12,171. The expenses paid under the above arrangement is included
in "custodian fees" on the Statement of Operations with the corresponding
expense offset shown as "expenses paid indirectly."



2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH
   AFFILIATES

In accordance with the terms of its investment management agreement, the Fund
pays Delaware Management Company (DMC), a series of Delaware Management Business
Trust and the investment manager, an annual fee which is calculated daily at the
rate of 0.55% on the first $500 million of average daily net assets of the Fund,
0.50% on the next $500 million, 0.45% on the next $1.5 billion, and 0.425% on
average daily net assets in excess of $2.5 billion.

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. The Fund pays
DSC a monthly fee based on the average net assets subject to certain minimums
for accounting and administration services. The Fund pays DSC a monthly fee
based on the number of shareholder accounts for dividend disbursing and transfer
agent services.

Pursuant to a distribution agreement and distribution plan, the Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.30% of the average daily net
assets of the Class A shares and 1.00% of the average daily net assets of the
Class B and C shares. DDLP has contracted to waive distribution and service fees
through April 30, 2005 in order to prevent distribution and service fees of
Class A shares from exceeding 0.25% of average daily net assets.

At August 31, 2004, the Fund had liabilities payable to affiliates as follows:

  Investment management fee payable to DMC                   $289,368
  Dividend disbursing, transfer agent,
    accounting and administrative fees, and
    other expenses payable to DSC                             $49,254
  Other expenses payable to DMC and affiliates*              $151,250

*DMC, as part of its administrative services, pays operating expenses on behalf
 of the Fund and is reimbursed on a periodic basis. Such expenses include items
 such as printing of shareholder reports, fees for audit, legal, and tax
 services, registration fees and trustees' fees.

As provided in the investment management agreement, the Fund bears the cost of
certain legal service expenses, including in-house legal services provided to
the Fund by DMC employees. For the six months ended August 31, 2004, the
Delaware Tax-Free Pennsylvania Fund had costs of $8,493.

For the six months ended August 31, 2004, DDLP earned $23,594 for commissions on
sales of the Fund's Class A shares.

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

3. INVESTMENTS
For the six months ended August 31, 2004, the Fund made purchases of $25,457,639
and sales of $50,283,309 of investment securities other than short-term
investments.

At August 31, 2004, the cost of investments for federal income tax purposes has
been estimated since the final tax characteristics cannot be determined until

  TO FINANCIAL STATEMENTS (CONTINUED)


4. DIVIDEND AND DISTRIBUTION INFORMATION
Income and long-term capital gain distributions are determined in accordance
with federal income tax regulations, which may differ from U.S. generally
accepted accounting principles. The tax character of dividends and distributions
paid during the six months ended August 31, 2004 and the year ended February 29,
2004 was as follows:

                                                     8/31/04         2/29/04
                                                   -----------     -----------
  Tax-exempt income                                $14,501,362     $30,561,819

*Tax information for the six months ended August 31, 2004 is an estimate and the
 tax character of dividends and distributions may be redesignated at fiscal year
 end.

The components of net assets are estimated since the final tax characteristics
cannot be determined until fiscal year end. As of August 31, 2004, the estimated
components of net assets on a tax basis were as follows:

  Shares of beneficial interest                        $618,033,775
  Capital loss carryforwards                            (19,005,154)
  Unrealized appreciation of investments                 36,150,936
                                                       ------------
  Net assets                                           $635,179,557
                                                       ============

The difference between book basis and tax basis components of net assets are
primarily attributable to tax deferral of losses on wash sales.

At February 29, 2004, for federal income tax purposes, the Fund had capital loss
carryforwards of $18,712,137 which may be carried forward and applied against
future capital gains. Such capital loss carryforwards expire as follows:
$9,227,179 expires in 2008, $8,323,306 expires in 2009, and $1,161,652 expires
in 2010.

For the six months ended August 31, 2004, the Fund had capital losses of
$293,017 which may be added to the capital loss carryforwards.



5. CAPITAL SHARES
Transactions in capital shares were as follows:

                                                     ==========     ===========

For the six months ended August 31, 2004 and the year ended February 29, 2004,
257,898 Class B shares were converted to 257,898 Class A shares valued at
$2,071,440 and 238,898 Class B shares were converted to 238,898 Class A shares
valued at $1,933,320, respectively. The respective amounts are included in Class
B redemptions and Class A subscriptions in the table above and the Statement of
Changes in Net Assets.

6. LINE OF CREDIT
The Fund, along with certain other funds in the Delaware Investments Family of
Funds (the "Participants"), participates in a $177,300,000 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. The
Fund had no amounts outstanding as of August 31, 2004, or at any time during the
period.

7. CREDIT AND MARKET RISKS
The Fund concentrates its investments in securities issued by Pennsylvania
municipalities. The value of these investments may be adversely affected by new
legislation within Pennsylvania, 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
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.

8. CONTRACTUAL OBLIGATIONS
The Fund enters into contracts in the normal course of business that contain a
variety of indemnifications. The Fund's maximum exposure under these
arrangements is unknown. However, the Fund has not had prior claims or losses
pursuant to these contracts. Management has reviewed the Fund's existing
contracts and expects the risk of loss to be remote.
