EVERGREEN TAX FREE FUND (FORMERLY KEYSTONE TAX FREE FUND)          February 1998

Dear Shareholders:

                 While stocks captured headlines for investors seeking growth
(Photograph of   over the past year, municipal bonds continued to reward
William M.       income-oriented investors with both attractive total return and
Ennis)           tax-advantaged income. The Lehman Brothers Municipal Bond Index
                 produced a total return of 9.19% for the twelve months ended on
                 December 31, 1997. Further, the average AAA-rated municipal
                 bond yielded approximately 5.00%-- 85% of that of U.S.
WILLIAM M.       Treasuries with comparable maturities-- also as of that date. A
ENNIS            taxable investment would need to yield 7.25% for investors in
                 the 31% federal income tax bracket to match the yield provided
                 by a AAA-rated municipal bond, a tall order in an environment
                 where the benchmark 30-year U.S. Treasury yields under 6%.
                 These returns are especially attractive when one considers that
                 inflation, measured by the consumer price index, stood at 1.7%
                 for all of 1997.
                   The U.S. experienced an extremely favorable investment
                 environment throughout most of last year. Steady economic
                 growth combined with minimal inflation pressures, a declining
                 federal budget deficit and strong
foreign demand stimulated a rally in the fixed-income market that drove interest
rates to their lowest levels in 20 years. Foreign investors, in particular,
sought the U.S. as a safe haven from the upheaval taking place in the Asian
financial markets.
  In the tax-exempt sector, state and local governments reaped higher tax
revenues from this steady economic growth. Improved cash flows strengthened
municipalities from a credit standpoint. These improved financial operations
also reduced the need to issue municipal bonds, lowering supply and helping
support prices.
  As we head into 1998, many of the trends we witnessed over the last year still
appear to be in place. High levels of consumer confidence and brisk employment
growth suggest that the economy can continue to grow at a healthy pace and there
is an increasing confidence among many investors that worldwide improvements in
technology and productivity can enable further economic expansion with few
inflationary pressures. We believe this backdrop bodes well for fixed income
investors.
  Despite the economic health we are enjoying in the U.S., however, the
situation in Asia continues to be unsettled. A slowdown in Asia could have a
significant effect on our domestic economy, reducing growth in the U.S. and
lowering inflation from the minimal levels we have experienced to date. We
expect that much of the outlook for the U.S. economy, as well as the direction
of interest rates, will depend on the resolution of the Asian crisis.
  The events in the world's markets have served as a reminder of the value of an
income-oriented, high quality investment. The importance of an income-oriented
investment to a well rounded portfolio grows further when one stops to think
about the stage in life that baby-boomers are reaching. As retirement
approaches, investors typically prefer securities that generate a stable income
over riskier, more volatile investments.
  On an administrative note, we are pleased to report that shareholders of the
Keystone Tax Free Fund and the Evergreen Tax Free Income Fund have approved a
proposal to reorganize these funds into a new fund, the Evergreen Tax Free Fund.
The new fund's investment objective is substantially the same as that of the
former funds and will be managed by Betsy Hutchings. The reorganization of these
funds took place on January 23, 1998.
  A discussion with your fund manager follows this letter, providing a detailed
account of the market conditions and strategies that shaped your fund's
performance. We wish you all a healthy and prosperous 1998.

Sincerely,

/s/William M. Ennis

William M. Ennis

                               A Discussion With
                              Your Fund's Manager

                        (Photgraph of Betsy A. Hutchings)

   BETSY A. HUTCHINGS, A SENIOR VICE PRESIDENT AND HEAD OF THE MUNICPAL BOND
   TEAM OF KEYSTONE INVESTMENT MANAGEMENT COMPANY, IS PORTFOLIO MANAGER OF
   THE FUND. MS. HUTCHINGS HAS MORE THAN 15 YEARS OF EXPERIENCE IN INVESTMENT
   MANAGEMENT AND HAS MANAGED THE FUND SINCE 1990.

Q WHAT WAS THE ENVIRONMENT LIKE FOR MUNICIPAL BONDS OVER THE LAST TWELVE MONTHS?

A The environment was favorable for most of the period. Interest rates fell, as
moderate economic growth continued to be accompanied by low inflation. The
federal budget deficit declined and foreign demand for U.S. government
securities was strong. For state and local governments, the economy's strength
produced higher tax revenues. Improved cash flows strengthened municipal balance
sheets and reduced the need to issue tax-exempt bonds.
  These positive market conditions contrasted dramatically with the investment
environment that prevailed in the early part of last year. Concerned that
stronger economic growth would revive inflationary pressures, investors forced
interest rates higher and bond prices lower, at that time. In March 1997, the
Federal Reserve Board raised the federal funds rate--the rate at which banks
lend to each other overnight and the benchmark for short-term interest
rates--from 5 1/4% to 5 1/2%, in an attempt to prevent a rise in price
pressures.
  Although municipal bond and U.S. Treasury yields experienced similar trends
over the past twelve months, there were times when supply and demand factors in
the respective markets caused the yields in each sector to move in different
directions. One of these periods occurred in the fourth quarter when heavier
municipal supply combined with lackluster demand, putting downward pressure on
tax-exempt bond prices. At the same time, a "flight to quality" in the U.S.
Treasury market--stemming from the Asian currency crisis--caused the prices of
comparable U.S. Treasuries to rise. At that point, municipal bonds became very
"cheap" compared to U.S. Treasuries, based on historical standards. Typically
providing approximately 85% of the yield of U.S. Treasuries with comparable
maturities, the yields of AAA-rated municipal bonds offered as much as 88% of
those of their U.S. government counterparts.

Q HOW DID THE FUND PERFORM DURING THAT TIME?

A We were satisfied with the Fund's performance. Evergreen Tax Free Fund
generated an attractive level of tax-exempt income and a solid total return over
the past year. We attribute these results to careful security selection and the
implementation of conservative, interest-rate-sensitive strategies.

Q WHAT STRATEGIES DID YOU USE IN MANAGING THE FUND?

A We emphasized quality, income and relative value. We also adjusted the
portfolio's sensitivity to interest rate changes.
  We increased the Fund's investment in AAA-rated bonds from 46% on December 31,
1996, to 58% on December 31, 1997, believing that AAA-rated bonds provided the
best relative value. During the year, the additional yield provided by
lower-rated bonds compared to their higher-rated counterparts sunk to
historically

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

low levels. The changing yield relationship between higher-rated bonds and
lower-rated bonds enabled us to increase the Fund's holdings in higher-rated
securities, while giving up only minimal yield.
  As part of our emphasis on quality, we increased the Fund's holdings in
higher-rated general obligation bonds. General obligation bonds benefited from
the economy's strength, with rising state and local tax revenues improving many
municipalities from a credit standpoint. We also scaled back on the Fund's New
York holdings as the year progressed. We had increased the Fund's investment in
New York municipal bonds when heavy supply had driven their prices lower and
yields higher than alternative investments. Their yields fell to the point where
we could take attractive profits and we believed we could find better value in
other bonds. As of December 31, 1997, the average quality of the Fund was AA+.
  We adjusted the Fund's maturity structure, actively managing its duration.
Duration measures a portfolio's sensitivity to interest rate changes. The longer
a portfolio's duration, the greater its sensitivity to changes in interest
rates. We increased the Fund's duration after interest rates rose to enhance
total return when interest rates later declined. We did this by selling
positions in the 5-10 year maturity range and reinvesting the proceeds in bonds
with 15-20 year maturities. We also invested in lower-coupon bonds and
zero-coupon bonds as part of this strategy.
  Later in the year, we shortened the Fund's duration--enhancing its price
stability--when market sentiment became negative and municipal bond prices
began to fluctuate. At that time, we reduced the Fund's holdings in bonds with
25-year maturities. We reinvested assets in pre-refunded bonds, which were rated
"AAA" because they were fully backed by U.S. government securities. They mature
in 2-10 years. The high quality and shorter maturities of pre-refunded bonds
make them one of the safest and most stable securities in the municipal bond
market.
  In the fourth quarter, we extended the Fund's duration when price volatility
subsided and our outlook for municipal bonds became more positive. We sold bonds
with 10-12 year maturities which, in our opinion, had become overvalued and
reinvested in bonds in the 22-25 year maturity range. We focused on zero coupon
bonds to enhance total return and on bonds with 5 3/4% to 6% coupons, which we
believed provided attractive relative value. As of December 31, 1997, the Fund's
average maturity was 19.1 years and its duration was 8.5 years.

Q WHAT IS YOUR OUTLOOK OVER THE NEXT SIX MONTHS?

A Our outlook is positive, although we are closely monitoring developments in
the Asian crisis. We expect many of the trends that drove interest rates lower
over the past year to continue. These include low inflation, a declining federal
budget deficit and strong foreign demand for U.S. government securities. We
believe, however, that turmoil in the Asian economies could have a substantial
effect on the U.S. economy and that will play an important role in determining
the future course of interest rates.

Past performance is no guarantee of future results. The investment return and
principal value will fluctuate so that an investor's shares, when redeemed, may
be worth more or less than original cost. The Lehman Municipal Bond Index is an
unmanaged market index. This index does not include transaction costs associated
with buying and selling securities nor any management fees. The Consumer Price
Index, a measure of inflation, is through December 31, 1997.

EVERGREEN TAX FREE FUND (FORMERLY KEYSTONE TAX FREE FUND)

NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES
 
Evergreen Tax Free Fund (the "Fund") (formerly, Keystone Tax Free Fund), a
Massachusetts business trust, is registered under the Investment Company Act of
1940, as amended (the "1940 Act"), as a diversified, open-end management
investment company.
  The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles, which
require management to make estimates and assumptions that affect amounts
reported herein. Actual results could differ from these estimates.
 
A. VALUATION OF SECURITIES
 
An independent pricing service values the Fund's municipal bonds at fair value
using a variety of factors which may include yield, liquidity, interest rate
risk, credit quality, coupon, maturity and type of issue. Securities for which
valuations are not available from an independent pricing service, including
restricted securities, are valued at fair value as determined in good faith
according to procedures established by the Board of Trustees.
  Short-term investments with remaining maturities of 60 days or less are
carried at amortized cost, which approximates market value.
 
B. FUTURES CONTRACTS
 
In order to gain exposure to or protect against changes in security values, the
Fund may buy and sell futures contracts.
  The initial margin deposited with a broker when entering into a futures
transaction is subsequently adjusted by daily payments or receipts as the value
of the contract changes. Such changes are recorded as unrealized gains or
losses. Realized gains or losses are recognized on closing the contract.
  Risks of entering into futures contracts include (i) the possibility of an
illiquid market for the contract, (ii) the possibility that a change in the
value of the contract may not correlate with changes in the value of the
underlying instrument or index, and (iii) the credit risk that the other party
will not fulfill their obligations under the contract. Futures contracts also
involve elements of market risk in excess of the amount reflected in the
statement of assets and liabilities.
 
C. DERIVATIVE SECURITIES
 
The Fund may invest in derivative securities. A derivative security is any
investment that derives its value from an underlying security, asset or market
index. Greater market fluctuations may result if these securities are leveraged.
The Fund invests in these types of securities when it is consistent with its
investment objectives.
 
D. SECURITY TRANSACTIONS AND INVESTMENT INCOME
 
Securities transactions are accounted for no later than one business day after
the trade date. Realized gains and losses are computed on the identified cost
basis. Interest income is recorded on the accrual basis and includes accretion
of discounts and amortization of premiums.
 
E. FEDERAL TAXES
 
The Fund has qualified and intends to continue to qualify as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code"). Thus, the Fund will not incur any federal income tax liability since it
is expected to distribute all of its net investment company taxable income, net
tax-exempt income and net capital gains, if any, to its shareholders. The Fund
also intends to avoid any excise tax liability by making the required
distributions under the Code. Accordingly, no provision for federal income taxes
is required. To the extent that realized capital gains can be offset by capital
loss carryforwards, it is the Fund's policy not to distribute such gains.

PAGE 25                                                                    
- ---------------------------------------------------------
 
F. DISTRIBUTIONS
 
Distributions from net investment income for the Fund are declared daily and
paid monthly. Distributions from net realized capital gains, if any, are paid at
least annually. Distributions to shareholders are recorded at the close of
business on the ex-dividend date.
  Income and capital gains distributions to shareholders are determined in
accordance with income tax regulations, which may differ from generally accepted
accounting principles. The significant differences between financial statement
amounts available for distributions and distributions made in accordance with
income tax regulations are primarily due to differing treatment of market
discount on securities.
 
2. CAPITAL SHARE TRANSACTIONS
 
The Fund has an unlimited number of shares of beneficial interest with no par
value authorized. Transactions in shares of the Fund were as follows:

3. SECURITIES TRANSACTIONS
 
Cost of purchases and proceeds from sales of investment securities (excluding
short-term securities) for the year ended December 31, 1997 were $1,774,258,295
and $1,991,612,017, respectively.
  On December 31, 1997, the federal tax cost of investment securities was
$1,292,335,986. The composition of gross unrealized appreciation, depreciation
and net unrealized appreciation was $87,693,203, ($6,436,141) and $81,257,062,
respectively.
  As of December 31, 1997, the Fund has no capital loss carryover for federal
income tax purposes.
 
4. DISTRIBUTION PLAN
 
Evergreen Distributor, Inc. ("EDI") (formerly, Evergreen Keystone Distributor,
Inc.), a wholly-owned subsidiary of The BISYS Group Inc. ("BISYS"), serves as
principal underwriter to the Fund.
  The Fund has adopted a Distribution Plan (the "Plan") as allowed by Rule 12b-1
of the 1940 Act. The Plan permits the Fund to reimburse its principal
underwriter for costs related to selling shares of the Fund and for various
other services. These costs, which consist primarily of commissions and services
fees to broker-dealers who sell shares of the Fund, are paid by shareholders
through expenses called "Distribution Plan expenses". Under the Distribution
Plan, the Fund pays a distribution fee which may not exceed 1.00% of the Fund's
average daily net assets, of which 0.75% is used to pay distribution expenses
and 0.25% may be used to pay shareholder service fees.
  The principal underwriter may pay distribution fees greater than the allowable
amounts the Fund is permitted to pay under the Plan. The Fund may reimburse EDI
for such excess amounts in later years with annual interest at prime plus 1%.
EDI intends to seek full payment of such distribution costs from the Fund at
such time in the future as, and to the extent that, payment thereof by the Fund
would be within permitted limits.
  The Plan may be terminated at any time by vote of the Independent Trustees or
by vote of a majority of the outstanding voting shares. However, after the
termination of the Plan, and subject to the discretion of the Independent
Trustees, payments to EDI may continue as compensation for services which had
been provided while the Plan was in effect.

EVERGREEN TAX FREE FUND (FORMERLY KEYSTONE TAX FREE FUND)
 
5. INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT AND OTHER AFFILIATED
TRANSACTIONS
 
Keystone Investment Management Company ("Keystone"), a subsidiary of First Union
Corporation ("First Union"), serves as the investment advisor and manager to the
Fund. In return for providing investment management and administrative services
to the Fund, the Fund pays Keystone a management fee that is calculated daily
and paid monthly. The management fee is computed at an annual rate of 2.00% of
the Fund's gross investment income plus an amount determined by applying
percentage rates, starting at 0.50% and declining to 0.25% per annum as net
assets increase, to the average daily net asset value of the Fund. Effective
January 1, 1997, BISYS became sub-administrator to the Fund and is paid by
Keystone for its services.
  In providing or obtaining additional operating services, facilities and
supplies to the Fund, Keystone had incurred other expenses which consisted of
transfer agent fees, custodian fees and other fees and expenses for the amounts
shown on the statement of operations. Keystone has been reimbursed for these
expenses by the Fund.
  Evergreen Investment Services, Inc. ("EIS") (formerly, Evergreen Keystone
Investment Services, Inc.), a wholly-owned subsidiary of First Union National
Bank, serves as the administrator to the Fund. The Fund reimbursed EIS for
accounting services provided on its behalf.
  Evergreen Service Company ("ESC") (formerly, Evergreen Keystone Service
Company), a wholly-owned subsidiary of Keystone, serves as the transfer and
dividend disbursing agent for the Fund.
  Officers of the Fund and affiliated Trustees receive
no compensation directly from the Fund. As sub-administrator, BISYS compensates
the officers of the Fund.
 
6. EXPENSE OFFSET ARRANGEMENT
 
The Fund has entered into an expense offset arrangement with its custodian. The
assets deposited with the custodian under this expense offset arrangement could
have been invested in income-producing assets.
 
7. FUND REORGANIZATION
 
On February 29, 1996, the Fund acquired the net assets of Keystone Tax Exempt
Trust in exchange for shares of the Fund pursuant to a plan of reorganization
approved by the shareholders of Keystone Tax Exempt Trust on February 29, 1996.
The acquisition was accomplished by a tax-free exchange of shares of the Fund
for the net assets of Keystone Tax Exempt Trust. The net assets of Keystone Tax
Exempt Trust on that date, including $40,609,975 of unrealized appreciation on
investments, were combined with the Fund. The aggregate net assets of the Fund
and Keystone Tax Exempt Trust immediately before the acquisition were
$1,142,691,716 and $658,278,376, respectively. The net assets of the Fund
immediately after the acquisition were $1,800,970,092.
 
8. FINANCING AGREEMENT
 
On December 22, 1997, a financing agreement among all of the Evergreen Funds,
State Street Bank & Trust ("State Street") and a group of Banks (collectively,
the "Banks") became effective. Under this agreement, the Banks provide an
unsecured credit facility in the aggregate amount of $400 million ($275 million
committed and $125 million uncommitted). The credit facility is allocated, under
the terms of the financing agreement, among the Banks. The credit facility is to
be accessed by the Funds for temporary or emergency purposes only and is subject
to each fund's borrowing restrictions. Borrowings under this facility bear
interest at 0.50% per annum above the Federal Funds rate. A commitment fee of
0.065% per annum will be incurred on the unused portion of the committed
facility, which will be allocated to all funds. For its assistance in arranging
this financing agreement, the Capital Market Group of First Union was paid a one
time arrangement fee of $27,500. State Street serves as administrative agent for
the Banks, and as administrative agent is entitled to

- ---------------------------------------------------------
 
a fee of $20,000 per annum which is allocated to all of the funds.
  During the year ended December 31, 1997, the Fund had no borrowings under this
agreement.
 
9. SUBSEQUENT EVENTS
 
Effective January 9, 1998, the Fund added two classes of shares designated as
Class A and Class C and designated the existing class of shares as Class B.
Class A shares are sold with a maximum front-end sales charge of 4.75%. Class B
and Class C shares are sold without a front-end sales charge, but pay a higher
ongoing distribution fee than Class A. Class B shares are sold subject to a
contingent deferred sales charge that is payable upon redemption and decreases
depending on how long the shares have been held. Class C shares are sold subject
to a contingent deferred sales charge payable on shares redeemed within one year
after the month of purchase. Shareholders of the Fund who, on January 16, 1998,
held Class B shares purchased before January 1, 1995 and certain other
non-commissionable Class B shares had such shares converted to Class A shares
having an aggregate value equal to that of the shareholder's Class B shares
prior to the conversion.
  At a shareholder meeting on January 6, 1998, the shareholders of the Fund
approved the acquisition of substantially all assets and certain liabilities of
the Fund by Evergreen Tax Free Fund ("Evergreen Tax Free"), a series of
Evergreen Municipal Trust, a Delaware business trust, in exchange for Class A,
Class B and Class C shares of Evergreen Tax Free. Also at a meeting on January
6, 1998, the shareholders of Evergreen Tax Free Income Fund ("Tax Free Income"),
a Massachusetts business trust, approved the acquisition of substantially all of
its assets and certain liabilities by Evergreen Tax Free in exchange for Class
A, Class B and Class C shares of Evergreen Tax Free. Tax Free Income had net
assets of approximately $103 million at December 31, 1997. On January 23, 1998,
this acquisition was accomplished by a tax-free exchange of the respective
shares of the Funds.

INDEPENDENT AUDITORS' REPORT
 
THE TRUSTEES AND SHAREHOLDERS
EVERGREEN TAX FREE FUND
 
We have audited the accompanying statement of assets and liabilities of
Evergreen Tax Free Fund (formerly, Keystone Tax Free Fund), including the
schedule of investments, as of December 31, 1997, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period then ended and the financial highlights
for each of the years in the ten-year 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 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 December 31, 1997 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
Evergreen Tax Free Fund, as of December 31, 1997, the results of its operations
for the year then ended, the changes in its net assets for each of the years in
the two-year period then ended, and the financial highlights for each of the
years in the ten-year period then ended in conformity with generally accepted
accounting principles.
