HOW TO USE THIS REPORT
 
For a quick overview of the fund's performance during the past twelve months,
refer to the Highlights box below. The letter from the portfolio manager and
president provides a more detailed analysis of the fund and financial markets.
 
The charts alongside the letter are useful because they provide more information
about your investments. The top holdings charts show the types of securities in
which the fund invests, and the pie chart shows a breakdown of the fund's assets
by industry.
 
The performance chart graphically compares the fund's total return performance
with a selected investment index. Remember, however, that an index may reflect
the performance of securities the fund may not hold. Also, the index does not
deduct sales charges, investment advisory fees and other fund expenses, whereas
your fund does. Individuals cannot buy an unmanaged index fund without incurring
some charges and expenses.
 
This report is just one of several tools you can use to learn more about your
investment in the Fortis Family of Mutual Funds. Your investment representative,
who understands your personal financial situation, can best explain the features
of your investment and how it's designed to help you meet your financial goals.

DEAR SHAREHOLDER,
 
Offering tax-free income, the Fortis Tax-Free Portfolios invest in high quality
municipal bonds. These portfolios are designed to help you reduce your tax
burden as they help to revitalize the country by investing in America.
 
This past year, due to specific actions detailed below, we helped the National
Portfolio outperform the majority of national municipal bond funds. Similar
activities in the Minnesota Portfolio enhanced its performance to place it
within the upper two-thirds of similar funds. However, because of efforts to
limit taxable gains, the New York Portfolio underperformed its peer group.
 
DIVERSE ECONOMIC CONDITIONS
 
The bond market has digested a wide variety of economic information during the
past 12 months. Late in 1995, the bond market responded favorably to an economic
environment that indicated modest economic growth and little inflation. But this
scenario changed abruptly in the first and second quarters when monthly
employment statistics indicated stronger economic growth. Concern that this
growth could increase inflation and cause the Federal Reserve to raise interest
rates led the U.S. Treasury long bond rate to move from 6 percent in late
January to slightly over 7 percent in mid-July.
 
More recently, the subdued September employment statistics and other recent
economic indicators lead us to believe that real growth continues at a more
modest and sustainable pace of about 2 percent. In this environment, there is
less concern that the Federal Reserve will raise interest rates.
 
PORTFOLIOS REPOSITIONED AS INTEREST RATES ROSE
 
Late last year, in order to benefit from expected price appreciation, we
positioned the portfolios with durations* or effective maturities longer than
their respective benchmarks (a measure of reference against which the fund is
compared and evaluated). As the likelihood of accelerated growth and rising
rates increased during the first quarter of 1996, we shifted to a more defensive
posture, with durations closer to their respective benchmarks. Since March, we
have maintained a basically neutral duration position, which we expect to
maintain until economic signals are more clear.
 
At the end of 1995 and in early 1996, the addition of call protection (the
amount of time during which a security cannot be redeemed by the issuer)
lengthened the effective maturities of the National and Minnesota Portfolios.
Specifically, call protection increased by more than two years in the National
Portfolio and by one year in the Minnesota Portfolio. In so doing, performance
in these two portfolios was enhanced, while interest rates declined. To limit
taxable gains, transactions in the New York Portfolio were few.
 
RISK/RETURN PROFILES CONTINUE TO IMPROVE
 
Durations of the National and Minnesota Portfolios were reduced when market
sentiment shifted in the first and second quarters, though not quickly enough to
prevent modest underperformance in comparison to their respective peer groups.
Since March 1996, municipal yields have fluctuated within a 35 basis point
range. (One basis point represents 0.01 percent of yield, the smallest measure
used to quote bond performance.) During August and September, some of the bonds
purchased in late 1995 and early 1996 were sold and replaced with bonds having
comparable performance characteristics and higher yields.
 
Looking forward, we will continue to improve the risk and return profiles of the
portfolios. Special attention will be given to credit quality, call protection
and other aspects of bond structure, as we seek to enhance portfolio
performance.
 
WE APPRECIATE YOUR INVESTMENT
 
Today's economic and investment climates remain ever-changing, and we appreciate
your trust in us as we manage these portfolios for you. If you have any
questions, please call us or your investment professional.
 
Sincerely,

*An important concept in managing fixed income securities, duration is the
measure of a bond fund's sensitivity to interest rate changes. Traditionally
measured in years, higher durations mean potentially greater fluctuations in
bond values, just as lower durations typically mean less volatility.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Fortis Tax-Free Portfolios, Inc.
   (the fund) is an open-end management investment company which currently is
   comprised of three separate investment portfolios and series of capital
   stock: the National and Minnesota Portfolios, both of which are diversified
   portfolios, and the New York Portfolio, which is a non-diversified portfolio,
   each of which has different investment objectives and its own investment
   portfolio and net asset values. The investment objective of National
   Portfolio is to seek as high a level of current income exempt from federal
   income tax as is believed to be consistent with preservation of capital. The
   investment objective of Minnesota Portfolio is to seek as high a level of
   current income exempt from federal and Minnesota income tax as is believed to
   be consistent with preservation of capital. The investment objective of New
   York Portfolio is to seek as high a level of current income exempt from
   federal, New York State, and New York City income tax as is believed to be
   consistent with the preservation of capital.
 
   The Minnesota and New York Portfolios concentrate their investments in a
   single state and, therefore, may have more credit risk related to the
   economic conditions of the respective state than a portfolio with broader
   geographical diversification.
 
   The fund offers Class A, Class B, Class C, Class E and Class H shares. The
   fund began to issue class shares effective November 14, 1994. Class E shares
   are only available to existing shareholders on November 14, 1994. Class A and
   E shares are sold with a front-end sales charge. Class B and H shares are
   sold without a front-end sales charge and may be subject to a contingent
   deferred sales charge for six years, and such shares automatically convert to
   Class A after eight years. Class C shares are sold without a front-end sales
   charge and may be subject to a contingent deferred sales charge for one year.
   All classes of shares have identical voting, dividend, liquidation and other
   rights and the same terms and conditions, except that the level of
   distribution fees charged differs between classes. Income, expenses (other
   than expenses incurred under each class's distribution agreement) and
   realized and unrealized gains or losses on investments are allocated to each
   class of shares based on its relative net assets.
 
   The significant accounting policies followed by the fund are summarized as
   follows:
 
   SECURITY VALUATION: Securities for which over-the-counter market quotations
   are readily available are valued on the basis of the last current bid price.
   An outside pricing service may be utilized to provide such valuations. The
   pricing service may employ electronic data processing techniques and/or a
   matrix system to determine valuations using methods which include
   consideration of yields or prices of municipal bonds of comparable quality,
   type of issue, coupon, maturity and rating; indications as to value from
   dealers; and general market conditions. Securities for which quotations are
   not readily available are valued at fair value as determined in good faith by
   management under supervision of the Board of Directors. Short-term
   investments, with maturities of less than 60 days when acquired, or which
   subsequently are within 60 days of maturity, are valued at amortized cost.
 
   SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME: Security transactions
   are accounted for on the trade date. Interest income is recorded on the
   accrual basis. Realized security gains and losses are determined using the
   identified cost method. For financial reporting purposes, the portfolios
   amortize long-term bond premium and original issue discount.
 
   For the year ended September 30, 1996, the cost of purchases and proceeds
   from sales of securities (other than short-term securities) aggregated
   $41,454,824 and $38,809,617 for National Portfolio; $21,926,224 and
   $22,891,399 for Minnesota Portfolio; and $1,305,200 and $2,384,140 for New
   York Portfolio; respectively.
 
   INCOME TAXES: The portfolios intend to qualify, under the Internal Revenue
   Code, as regulated investment companies and if so qualified, will not have to
   pay federal income taxes to the extent their taxable net income is
   distributed. On a calendar year basis, the fund intends to distribute
   substantially all of its taxable net investment income and realized gains, if
   any, to avoid the payment of federal excise taxes.
 
   Net realized gains may differ for financial statement and tax purposes
   primarily because of wash sale transactions. The character of distributions
   made during the year from net investment income or net realized gains may
   also differ from their ultimate characterization for federal income tax
   purposes. Also, due to the timing of dividend distributions, the fiscal year
   in which amounts are distributed may differ from the year that the income or
   realized gains (losses) were recorded by the fund.
 
   For federal income tax purposes the National and Minnesota Portfolios had the
   following capital loss carryovers at September 30, 1996, which, if not offset
   by subsequent capital gains, will expire in 2002 and 2003 for the National
   Portfolio, and in 1997, 2002 through 2004 for the Minnesota Portfolio:
   National Portfolio $445,336; Minnesota Portfolio $435,340. It is unlikely the
   Board of Directors will authorize a distribution of any net realized gains
   until the available capital loss carryovers have been offset or expired.
 
   DEFERRED COSTS: Registration costs are deferred and charged to income over
   the registration period.
 
   INCOME AND CAPITAL GAINS DISTRIBUTION: The portfolios declare income
   distributions daily to be paid on the last business day of each month. The
   portfolios will make annual distributions of any realized capital gains as
   required by law. These income and capital gains distributions may be
   reinvested in additional shares of the portfolio at net asset value on the
   payable date or paid in cash five business days after month end without any
   charge to the shareholder.
 
   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 increase and decrease in net assets from operations during the reporting
   period. Actual results could differ from those estimates.
 
2. PAYMENTS TO RELATED PARTIES: Fortis Advisers, Inc. (Advisers), is the
   investment adviser for the fund. Investment advisory fees paid by the
   Minnesota and New York Portfolios are computed at an annual rate of .8% of
   the first $50 million in average daily net assets, .7% of the next $50
   million in average daily net assets and .625% of average daily net assets in
   excess of $100 million. The National Portfolio's investment advisory fees are
   computed at an annual rate of .8% of the first $50 million in average daily
   net assets, and .7% of average daily net assets in excess of $50 million. The
   fee percentage for the Minnesota Portfolio is based upon the

- --------------------------------------------------------------------------------
   aggregate average net assets of the National and Minnesota Portfolios
   combined. The fee is then allocated to the Minnesota Portfolio based upon
   proportionate net assets. The fee percentage for National and New York
   Portfolio is based upon the average net assets of each portfolio alone.
 
   In addition to the investment advisory and management fee, Classes A, B, C
   and H pay Fortis Investors, Inc. (the fund's principal underwriter)
   distribution fees equal to .25% (Class A) and 1.00% (Class B, C, and H) of
   average daily net assets (of the respective classes) on an annual basis, to
   be used to compensate those who sell shares of the fund and to pay certain
   other expenses of selling fund shares. Fortis Investors, Inc., also received
   sales charges (paid by purchasers or redeemers of the fund's shares)
   aggregating:

   Portfolio (exclusive of interest, taxes, brokerage commissions, 12b-1 fees
   and non-recurring extraordinary charges and expenses) commencing November 1,
   1994 to 1.09% of average daily net assets. During the year ended September
   30, 1996, Advisers waived $24,580 of its advisory fee.
 
   Legal fees and expenses aggregating $8,474, $6,346 and $2,274 for the
   National, Minnesota, and New York Portfolios, respectively, were paid to a
   law firm of which the secretary of the fund is a partner.
 
3. PROPOSED FUND REORGANIZATION: On March 21, 1996, the fund's Board of
   Directors approved a proposed reorganization by which the New York Portfolio
   will be combined into the Voyageur New York Tax Free Fund, which is managed
   by Voyageur Fund Managers, Inc. This reorganization is subject to approval by
   New York Portfolio shareholders at a special shareholder meeting to be held
   November 12, 1996.

Fortis Tax-Free Portfolios, Inc.:
 
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of National Portfolio, Minnesota
Portfolio and New York Portfolio (portfolios within Fortis Tax-Free Portfolios,
Inc.) as of September 30, 1996, and the related statements of operations for the
year then ended, the statements of changes in net assets for each of the years
in the two-year period ended September 30, 1996, and the financial highlights
presented in footnote 4 to the financial statements. These financial statements
and the financial highlights are the responsibility of fund management. Our
responsibility is to express an opinion on these financial statements and the
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 the 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. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered, we
request confirmations from brokers, and where replies are not received, we carry
out other appropriate auditing procedures. 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 the financial highlights referred
to above present fairly, in all material respects, the financial position of
National Portfolio, Minnesota Portfolio and New York Portfolio at September 30,
1996 and the results of their operations for the year then ended, the changes in
their net assets for each of the years in the two-year period ended September
30, 1996, and the financial highlights presented in footnote 4 to the financial
statements, in conformity with generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION
 
Exempt interest dividends are exempt from federal income taxes and should not be
included in shareholder's gross income, but need to be reported on the income
tax return for informational purposes. Each shareholder should consult a tax
adviser about reporting this income for state and local tax purposes. In
January, 1997, the fund will provide the shareholder with information regarding
the percentage of distributions exempt from federal income taxes and a breakdown
setting forth states from which income was earned.
 
During the year ended September 30, 1996, 100% of the National, Minnesota and
New York Portfolios' distributions were derived from interest on municipal
securities and qualify as exempt interest dividends for federal tax purposes.
 
Detailed below are the per share distributions made for the year ended September
30, 1996.
