Q: What was the investment environment like for Delaware Tax-Free Pennsylvania
Fund during the fiscal year ended February 28, 2006?

Changes in interest rates and municipal bond refinancings were among the key
stories in the municipal bond market during the fiscal year. The Federal Reserve
Board maintained its policy of tightening U.S. monetary policy, aimed at keeping
inflation in check. This included a continuous string of eight quarter-point
increases to the fed funds rate, which took this target for short-term interest
rates from 2.50% on February 28, 2005 to 4.50% as of February 28, 2006 (source:
Bloomberg).

Despite the fed's actions on short-term interest rates, longer term rates did
not follow suit and generally remained low throughout the course of the fiscal
year. The 30-year Treasury bond yield, for instance, actually declined over the
course of the fiscal year, from 4.70% at the start of the year to 4.51% on
February 28, 2006. Similarly, the 30-year municipal bond yield declined from
4.48% to 4.36% during the same period (source: Bloomberg).

Due to their tax-advantaged status, municipal bonds typically trade at lower
yields than Treasury securities. During the year, municipals generally held
their value compared to Treasuries. Although the relationship varied throughout
the year, yields on 30-year AAA-rated municipals -- measured as a percentage of
the yield on long Treasury bonds -- started the fiscal year at 95.8% and ended
the year with yields at about 95.5% of the long Treasury bond on February 28,
2006 (source: Thomson Financial).

Rising short-term rates, coupled with long-term rates' downward trend, created a
situation that economists typically refer to as a "flattening yield curve." That
is, the difference between short- and long-term bond yields grows smaller across
the spectrum of maturities.

In this type of environment, bonds with intermediate maturities -- those in the
three- to seven-year maturity range -- frequently underperform. We found this to
be particularly true during the second half of the fiscal year, when the
flattening of the yield curve became more pronounced.

Credit quality among municipal bond issuers generally improved during the fiscal
year, and it was another factor influencing the markets. As a result of
improving credit quality, demand generally increased for high yield -- or
non-investment grade -- bonds. High yield securities performed well. Similarly,
among investment grade municipal bonds, lower-rated securities often
outperformed higher-rated securities by a significant margin on a total return
basis.

Q: What other market-related events influenced Fund performance?

Issuance of new municipal bonds remained strong during most of the fiscal year.
Supply of new municipal bonds is typically assessed on a calendar year basis
and, supply in calendar 2005 totaled a record $408 billion. New issuance in 2005
for the Commonwealth of Pennsylvania increased 28% to total $17.8 billion
(source: Municipal Market Data).

Driving that record issuance was low interest rates, which provided many issuers
with refinancing opportunities. We believe the ability of the market to absorb
additional supply was aided by non-traditional buyers (buyers more interested in
the relative valuation of the asset class than the tax-advantaged status of
municipal bonds). As more and more municipal issuers

                                        1


refinanced in 2005, new issuance dropped off. By the first months of 2006, the
rate of new issuance had declined significantly.

The economy in Pennsylvania generally grew, and is expected to continue to do
so, as a result of the $2 billion in-state economic stimulus and the recent
approval of legalized gaming (slots). Gaming is expected by some estimates to
create more than $1 billion of annual revenue, which would be used to lower
local school property taxes. Debt issued over a four year period is expected to
fund the economic stimulus program. This funding, combined with private
investments, will be invested in economic development projects within the state.
We believe Pennsylvania benefits from a low debt burden and a well-funded state
pension system.

Pennsylvania has long been known as a heavily industrialized state; however,
much has changed in recent years. We believe Pennsylvania now has a diverse
economic base, excellent educational facilities, and strong health care systems.
Although manufacturing jobs continue to decline, there have been employment
gains in education, health care, leisure/hospitality, and retail trade sectors.
Despite the recent strong economic showing, Pennsylvania is challenged by weak
demographics and below average employment growth. The Commonwealth's population
base is among the eldest in the nation.

Q: How did Delaware Tax-Free Pennsylvania Fund perform versus its benchmark
index and peer funds?

Delaware Tax-Free Pennsylvania Fund returned 3.97% at net asset value and -0.66%
at maximum offer price (both returns include distributions reinvested). By
comparison, the 61 funds in the Lipper Pennsylvania Municipal Debt Funds
category gained an average of 3.37% for the same period. The Fund's benchmark --
the national Lehman Brothers Municipal Bond Index -- gained 3.87%.

For complete, annualized performance for Delaware Tax-Free Pennsylvania Fund,
please see the table on page 4.

Q: What strategies did you pursue during the year, and how did they influence
the Fund's performance?

With a flattening yield curve and general outperformance by lower-rated
securities, the story throughout the Fund's fiscal year was often about actions
we chose not to take within the Fund, rather than those we did.

In the environment that prevailed, our approach to the municipal bond markets at
times dictated that we stay the course and ultimately resulted in limited
transactions. During the year, it was possible for municipal bond investors to
gain total return performance by favoring lower-rated bonds or by taking on
additional interest rate risk. Consistent with our philosophy, our approach was
to find and hold mid to low investment grade bonds with attractive income.

The objective of Delaware Tax-Free Pennsylvania Fund is a high level of current
interest income exempt from federal income tax and certain Pennsylvania state
and local taxes, with preservation of capital. During much of the year, our
preferred way to achieve that objective was to hold onto legacy bonds --
securities purchased in prior fiscal periods -- and to depend on the attractive
bond yields that already exist within our portfolio of investments. Generally
speaking, with interest rates in decline, it became increasingly difficult to
identify bonds in the marketplace that were more attractive than our holdings in
the portfolio. We believed that rotating out of these legacy bonds would only
serve to decrease the Fund's yield and potentially create undesirable taxable
events.

We adhered to our bottom-up investment style, which is based on
security-by-security analysis and a free exchange of information among the
various members of a deep team that includes portfolio managers, credit
analysts, and traders. Frequently during the year, we opted to focus our
resources on monitoring the credit of legacy bonds.

A key reason for maintaining the status quo much of the year is that we consider
the Fund a yield-oriented vehicle. One of the principles of our investment
approach is that we believe income is the most significant and predictable
component of total return over time. Price change is highly volatile and less
significant.

As such, we also do not typically make bold interest rate forecasts, and when we
do adjust the Fund's duration (a measure of the Fund's sensitivity to interest
rate changes), we attempt to track the average duration of our peer group. This
strategy proved beneficial during the fourth calendar quarter of 2005, as
economic uncertainty increased in the aftermath of the Gulf coast hurricanes.
During that volatile period in the market, Delaware Tax-Free Pennsylvania Fund
generally tracked the performance of its peer group. We did trim the Fund's
duration late in the fiscal year, in anticipation of further interest rate
increases.

During the course of the fiscal year, the Fund's makeup by sector and credit
rating was not strategically altered.

                                        2


Q: How did individual securities influence performance?

Bonds issued to finance hospitals and other healthcare-industry projects
outperformed during the fiscal year. These bonds are frequently lower-rated
investment grade issues (rated A or BBB), and their outperformance as a group
was in keeping with the trend of strong performance among lower-rated issues. An
example is a bond issued by Allegheny County Hospital Development Authority for
the Ohio Valley General Hospital.

Tax-free municipal bonds backed by corporations also frequently saw a measure of
gain. Bonds issued by the Pennsylvania Economic Development Authority for Amtrak
and Proctor & Gamble were among holdings in this category. The Amtrak bonds
performed well along with other lower-rated securities. The Proctor & Gamble
bonds outperformed because of their long duration.

In the declining interest rate environment, refundings and bond restructurings
occasionally influenced performance, with both positive and negative outcomes at
times. For example, several bonds in the Fund were prerefunded during the year.
When a bond becomes prerefunded, a new bond is issued, and the proceeds are
placed in escrow to be invested in U.S. Treasury securities. The proceeds
generated are then used to pay the principal and interest on the prerefunded
bond. As such, these bonds typically receive the highest credit ratings and
benefit from a price boost when they initially become prerefunded. A bond issued
to finance a Wellspan Heath Center was a Fund holding that became prerefunded.

On the other hand, bonds that were prerefunded in prior periods tend to
underperform as the yield curve flattens, as do bonds with short call dates. We
had holdings in these categories as well, which detracted from performance
versus the benchmark and peers.

Similarly, a bond issued by the Delaware County Industrial Development Authority
for Main Line Health was restructured during the year. This bond restructuring
caused the security to be a detractor for us when measuring relative performance
over the course of the fiscal year.

Q: How was the portfolio positioned at the end of the period, to begin the
2006-2007 fiscal year?

More than 70% of the securities in the portfolio were rated either AAA or AA,
and more than 96% of net assets were in securities with investment grade credit
ratings. Bonds supporting finance of educational institutions and hospitals
continued to be the Fund's largest sectors. We aimed to position the Fund
neutrally compared to our peers with regard to interest rate risk, expecting at
least some further rate hikes by the Fed in 2006. Our recent shortening of
duration is designed to be a conservative measure, as there is still some degree
of uncertainty with regard to the direction of the economy and the
intermediate-term interest rate outlook. We will continue to seek opportunities
to reposition the Fund, with the hope that future quarters may offer municipal
investors a more accommodating investment environment.

Returns reflect the reinvestment of distributions and any applicable sales
charges as noted below. Performance for Class B and C shares, excluding sales
charges, assumes either that contingent deferred sales charges did not apply or
the investment was not redeemed.

The Fund offers Class A, B, and C shares. Class A shares are sold with a
front-end sales charge of up to 4.50% and for periods after June 1, 1992, have
an annual distribution and service fee of up to 0.30%. The distributor has
contracted to limit this amount to 0.25% through June, 30 2006.

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 eight years after purchase. They are also subject to an annual
distribution and service fee of 1%. Lifetime and 10-year performance figures for
Class B shares reflect conversion to Class A shares after eight years.

Class C shares are sold with a contingent deferred sales charge of 1%, if
redeemed during the first 12 months. They are also subject to an annual
distribution and service fee of 1%.

An expense limitation was in effect for Class A shares of Delaware Tax-Free
Pennsylvania Fund during the periods shown. Performance would have been lower
had the expense limitation not been in effect.

The performance table does not reflect the deduction of taxes the shareholder
would pay on Fund distributions or redemptions of Fund shares.

Disclosure                 For the Period September 1, 2005 to February 28, 2006
- --------------------------------------------------------------------------------
   OF FUND EXPENSES

As a shareholder of the 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 September 1, 2005 to February 28, 2006.

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 of the table, 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 for Class A shares. The expenses shown in the table assume reinvestment
of all dividends and distributions.

(1)   Total investment return is based on the change in net asset value of a
      share for the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects waivers and payment of fees
      by the distributor, as applicable. Performance would have been lower had
      the expense limitation not been in effect.

                                             Delaware Tax-Free Pennsylvania Fund
Notes                                        February 28, 2006
- --------------------------------------------------------------------------------
   TO FINANCIAL STATEMENTS

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 eight 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 the 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. In determining whether market quotations are readily available or fair
valuation will be used, various factors will be taken into consideration, such
as market closures, aftermarket trading or significant events after local market
trading (e.g., government actions or pronouncements, trading volume or
volatility on markets, exchanges among dealers, or news events).

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(R) Family
of Funds are allocated amongst the funds on the basis of average net assets.
Management fees and some other expenses are paid monthly. Security transactions
are recorded on the date the securities are purchased or sold (trade date) for
financial reporting purposes. 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 expense paid
under the above arrangement is included in the custodian fees and on the
Statement of Operations with the corresponding expense offset shown as "expense
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. Effective June
1, 2005, the Fund pays DSC a monthly fee computed at the annual rate of 0.04% of
the Fund's average daily net assets for accounting and administration services.
Prior to June 1, 2005, the Fund paid DSC a monthly fee based on 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.

The Board of Trustees has adopted a formula for calculating 12b-1 plan fees for
the Fund's Class A shares that went into effect on June 1, 1992. The total 12b-1
fees to be paid by Class A shareholders of the Fund will be the sum of 0.10% of
the average daily net assets representing shares that were acquired prior to
June 1, 1992 and 0.30% of the average daily net assets representing shares that
were acquired on or after June 1, 1992. All Class A shareholders will bear 12b-1
fees at the same rate, the blended rate based upon the allocation of the 0.10%
and 0.30% rates described above. DDLP has contracted to waive distribution and
service fees through June 30, 2006 in order to prevent distribution and service
fees of Class A shares from exceeding 0.25% of average daily net assets. This
contractual waiver is applied to the shares of the Fund that were acquired on or
after June 1, 1992 in calculating the applicable 12b-1 fee rate.

At February 28, 2006, the Fund had liabilities payable to affiliates as follows:

   Investment management fees payable to DMC                     $   247,600
   Dividend disbursing, transfer agent, accounting
      and administration fees and other expenses
      payable to DSC                                                  48,419
   Distribution Fees Payable to DDLP                                 119,148
   Other expenses payable to DMC and affiliates*                      12,175

*     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 services expenses, including internal legal services provided to
the Fund by DMC employees. For the year ended February 28, 2006, the Fund was
charged $37,392 for internal legal services provided by DMC.

2.    Investment Management, Administration Agreements and Other Transactions
      with Affiliates (continued)

For the year ended February 28, 2006, DDLP earned $45,932 for commissions on
sales of the Fund's Class A shares. For the year ended February 28, 2006, DDLP
received gross contingent deferred sales charge commissions of $3,550, $17,373
and $807 on redemption of the Fund's Class A, Class B and Class C shares,
respectively and these commissions were entirely used to offset up-front
commissions previously paid by DDLP to broker-dealers on sales of those 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 year ended February 28, 2006, the Fund made purchases of $76,201,712 and
sales of $119,453,862 of investment securities other than short-term
investments.

At February 28, 2006, the cost of investments for federal income tax purposes
was $550,136,971. At February 28, 2006, net unrealized appreciation was
$38,740,353, of which $38,974,831 related to unrealized appreciation of
investments and $234,478 related to unrealized depreciation of investments.

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. Additionally, net short-term gains on sales of
investment securities are treated as ordinary income for federal income tax
purposes. The tax character of dividends and distributions paid during the years
ended February 28, 2006 and 2005 was as follows:

                                                        Year Ended
                                                   2/28/06        2/28/05
                                                ------------   -------------
   Tax-exempt income                            $ 25,984,710   $  28,586,626

As of February 28, 2006, the components of net assets on a tax basis were as
follows:

   Shares of beneficial interest                               $ 576,295,511
   Capital loss carryforwards                                    (18,994,533)
   Unrealized appreciation of investments                         38,740,353
                                                               -------------
   Net assets                                                  $ 596,041,331
                                                                =============

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

For federal income tax purposes, capital loss carryforwards may be carried
forward and applied against future capital gains. Capital loss carryforwards
remaining at February 28, 2006 will expire as follows: $9,193,068 expires in
2008, $8,323,306 expires in 2009, $1,161,652 expires in 2010 and $316,507
expires in 2014.

of Funds (the "Participants"), participates in a $225,000,000 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 fund's 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 February 28, 2006, or at any time during

   TO FINANCIAL STATEMENTS (CONTINUED)

7.    Credit and Market Risk

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 value 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.

The Fund may invest in inverse floating rate securities ("inverse floaters"), a
type of derivative tax-exempt obligation with floating or variable interest
rates that move in the opposite direction of short-term interest rates, usually
at an accelerated speed. Consequently, the market values of inverse floaters
will generally be more volatile than other tax-exempt investments. Such
securities are denoted on the Statement of Net Assets.

The Fund may invest in advanced refunded bonds, escrow secured bonds or defeased
bonds. Under current federal tax laws and regulations, state and local
government borrowers are permitted to refinance outstanding bonds by issuing new
bonds. The issuer refinances the outstanding debt to either reduce interest
costs or to remove or alter restrictive covenants imposed by the bonds being
refinanced. A refunding transaction where the municipal securities are being
refunded within 90 days or less from the issuance of the refunding issue is
known as a "current refunding". Advance refunded bonds are bonds in which the
refunded bond issue remains outstanding for more than 90 days following the
issuance of the refunding issue. In an advance refunding, the issuer will use
the proceeds of a new bond issue to purchase high grade interest bearing debt
securities which are then deposited in an irrevocable escrow account held by an
escrow agent to secure all future payments of principal and interest and bond
premium of the advance refunded bond. Bonds are "escrowed to maturity" when the
proceeds of the refunding issue are deposited in an escrow account for
investment sufficient to pay all of the principal and interest on the original
interest payment and maturity dates. Bonds are considered "pre-refunded" when
the refunding issue's proceeds are escrowed only until a permitted call date or
dates on the refunded issue with the refunded issue being redeemed at that time,
including any required premium. Bonds become "defeased" when the rights and
interests of the bondholders and of their lien on the pledged revenues or other
security under the terms of the bond contract are substituted with an
alternative source of revenues (the escrow securities) sufficient to meet
payments of principal and interest to maturity or to the first call dates.
Escrowed secured bonds will often receive a rating of AAA from Moody's
Investor's Service, Inc., Standard & Poor's Rating Group, and/or Fitch due to
the strong credit quality of the escrow securities and the irrevocable nature of
the escrow deposit agreement.

The Fund may invest up to 10% of its total assets in illiquid securities, which
may include securities with contractual restrictions on resale, securities
exempt from registration under Rule 144A of the Securities Act of 1933, as
amended, and other securities which may not be readily marketable. The relative
illiquidity of these securities may impair the Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so.
While maintaining oversight, the Fund's Board of Trustees has delegated to DMC
the day-to-day functions of determining whether individual securities are liquid
for purposes of the Fund's limitation on investments in illiquid assets. At
February 28, 2006, there were no Rule 144A securities and no securities have
been determined to be illiquid under the Fund's Liquidity Procedures.

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.

9.    Tax Information (Unaudited)

The information set forth below is for the 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 January of each
year. Please consult your tax advisor for proper treatment of this information.

For the fiscal year ended February 28, 2006, the Fund designates distributions
paid during the year as follows:

     (A)
  Long-Term          (B)
Capital Gains     Tax-exempt        Total
Distributions   Distributions   Distributions
 (Tax Basis)     (Tax Basis)     (Tax Basis)
- -------------   -------------   -------------
      --            100%             100%

(A) and (B) are based on a percentage of the Fund's total distributions.

Report
   OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees
Delaware Group State Tax-Free Income Trust -
Delaware Tax-Free Pennsylvania Fund

We have audited the accompanying statement of net assets of Delaware Tax-Free
Pennsylvania Fund (the sole series of Delaware Group State Tax-Free Income
Trust) (the "Fund") as of February 28, 2006, and the related statement 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 five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund'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 the standards of the Public Company
Accounting Oversight Board (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. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of February 28, 2006, by correspondence with the custodian.
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 the
Delaware Tax-Free Pennsylvania Fund of Delaware Group State Tax-Free Income
Trust at February 28, 2006, 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 its financial highlights for each of the five years in the
period then ended, in conformity with U.S. generally accepted accounting
principles.

Delaware Investments(R) Family of Funds
   BOARD OF TRUSTEES/DIRECTORS AND OFFICERS ADDENDUM

A mutual fund is governed by a Board of Trustees/Directors ("Trustees"), which
has oversight responsibility for the management of a fund's business affairs.
Trustees establish procedures and oversee and review the performance of the
investment manager, the distributor and others who perform services for the
fund. The independent fund trustees, in particular, are advocates for
shareholder interests. Each trustee has served in that capacity since he or she
was elected to or appointed to the Board of Trustees, and will continue to serve
until his or her retirement or the election of a new trustee in his or her
place. The following is a list of the Trustees and Officers with certain
background and related information.

Item 2.  Code of Ethics

         The registrant has adopted a code of ethics that applies to the
registrant's principal executive officer, principal financial officer, principal

regardless of whether these individuals are employed by the registrant or a

financial statements;

         b. The ability to assess the general application of such principles in
connection with the accounting for estimates, accruals, and reserves;

         c. Experience preparing, auditing, analyzing, or evaluating financial

experience actively supervising one or more persons engaged in such activities;

         d. An understanding of internal controls and procedures for financial
reporting; and

         e. An understanding of audit committee functions.

An "audit committee financial expert" shall have acquired such attributes
