[AIM LOGO APPEARS HERE] Dear Shareholder:
[PHOTO of The low-inflation, falling-interest-rate
Charles T. Bauer, environment that prevailed for much of the
Chairman of the fiscal year ended March 31, 1998, provided
LETTER Board of the Fund, nearly an ideal climate for financial markets.
TO OUR APPEARS HERE] For the 12-month period ended on that date,
SHAREHOLDERS consumer prices rose just 1.4% and the Federal
Reserve Board (the Fed) left interest rates unchanged. Borrowing
costs actually declined as the year progressed as it became
increasingly evident that inflation was not a serious threat.
Fixed-income securities also were given a boost by last
summer's agreement to balance the federal budget and the turmoil
that hit world stock markets in the fall. Investors began
shifting more assets into fixed-income securities after global
stock markets plunged in October following the Asian currency
devaluations. Early in 1998, however, the rally began to lose
some of its momentum as the economy continued to grow at a
healthy pace, dampening prospects that the Fed would lower
interest rates in the immediate future. Yields, which plunged to
their lowest levels in decades in January, climbed in February
and March, but were still relatively low at the end of the
reporting period.
YOUR INVESTMENT PORTFOLIO
For the fiscal year ended March 31, 1998, Cash Reserve Portfolio
maintained its competitive position, as shown in the table. The
Portfolio also maintained the quality of its holdings,
consistent with its AAAm credit quality rating, the highest
given by Standard & Poor's Corporation, a widely known credit
rating agency. The AAAm rating is historical and is based on an
analysis of the Portfolio's credit quality, composition,
management, and weekly portfolio reviews.
Cash Reserve Portfolio seeks to generate as high a level of
federally tax-exempt income as is consistent with preservation
of capital and maintenance of liquidity by investing in high-
quality, short-term municipal obligations. It invests solely in
securities rated "First Tier" as defined in Rule 2a-7 under the
Investment Company Act of 1940. Net assets of Institutional Cash
Reserve Shares of the Portfolio stood at $896.9 million at the
end of the reporting period.
As with any money market fund, your investment in Cash Reserve
Portfolio is neither insured nor guaranteed by the U.S.
government, the FDIC, the Federal Reserve Board, or any other
agency, and there can be no assurance the Portfolio will be able
to maintain a stable net asset value of $1.00 per share.

OUTLOOK FOR THE FUTURE
If the economy continues to grow at a steady pace and inflation
remains low, such conditions should bode well for fixed-income
securities. With inflation at bay and the full impact of the
Asian currency crisis still uncertain, the Fed could opt to
leave monetary policy unchanged in the months ahead. In his
late-February testimony to Congress, Fed Chairman Alan Greenspan
noted that the deflationary effects of turmoil in Asia could
offset the inflationary pressures from strong domestic spending
and a tight U.S. labor market.
If the Fed decides to leave interest rates unchanged in the
near future, we expect yields to remain within a relatively
narrow range around their current levels. If yields rise,
however, we believe the Fund is in a favorable position to take
advantage of such a trend.
We are pleased to send you this report concerning your
investment. AIM is committed to customer service and to the
primary goals of safety, liquidity and yield in institutional
fund management. We are ready to respond to your comments about
this report and to any questions you may have. Please contact

NOTES TO SCHEDULE OF INVESTMENTS:
(a) Ratings assigned by Moody's Investors Service, Inc. ("Moody's") and
Standard & Poor's Corporation ("S&P"). Ratings are not covered by
Independent Auditors' Report.
(b) Demand security: payable upon demand by the Fund at specified intervals no
greater than thirteen months. Interest rates are redetermined periodically.
Rates shown are the rates in effect on 03/31/98.
(c) Secured by a letter of credit.
(d) Secured by bond insurance.
(e) The Fund may invest in synthetic municipal instruments the value of and
return on which are derived from underlying securities. The types of
synthetic municipal instruments in which the Fund may invest include
variable rate instruments. These instruments involve the deposit into a
trust of one or more long-term tax-exempt bonds or notes ("Underlying
Bonds"), and the sale of certificates evidencing interests in the trust to
investors such as the Fund. The trustee receives the long-term fixed rate
interest payments on the Underlying Bonds, and pays certificate holders
short-term floating or variable interest rates which are reset
periodically. A "variable rate trust certificate" evidences an interest in
a trust entitling the certificate holder to receive variable rate interest
based on prevailing short-term interest rates and also typically providing
the certificate holder with the conditional right to put its certificate at
par value plus accrued interest. Because synthetic municipal instruments
involve a trust and a third party conditional put feature, they involve
complexities and potential risks that may not be present where a municipal
security is owned directly.
(f) Secured by an escrow fund of U.S. Treasury obligations.
(g) Subject to an irrevocable call or mandatory put by the issuer. Par value
and maturity date reflect such call or put.
(h) Also represents cost for federal income tax purposes.

NOTES TO FINANCIAL STATEMENTS
March 31, 1998
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
Tax-Free Investments Co. (the "Company") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Company is organized as a Maryland
corporation consisting of one portfolio, the Cash Reserve Portfolio (the
"Fund"). The Fund consists of two different classes of shares, the
Institutional Cash Reserve Shares ("Institutional Shares") and the Private
Investment Class. Matters affecting each class are voted on exclusively by the
shareholders of each class. The investment objective of the Fund is to generate
as high a level of tax-exempt income as is consistent with preservation of
capital and maintenance of liquidity.
The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements. The preparation of
financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
A. Securities Valuations - The Fund uses the amortized cost method of valuing
investment portfolio securities which has been determined by the Board of
Directors of the Company to represent the fair value of the Fund's
investments.
B. Securities Transactions and Investment Income - Securities transactions are
recorded on a trade date basis. Realized gains and losses from securities
transactions are computed on the basis of specific identification of the
securities sold. Interest income, adjusted for amortization of premiums and,
when appropriate, discounts on investments, is earned from settlement date
and is recorded on the accrual basis. Interest income is allocated to each
class daily, based upon each class' pro rata share of the total shares of
the Fund outstanding. Discounts, other than original issue, on short-term
obligations are amortized to unrealized appreciation for financial reporting
purposes.
C. Dividends and Distributions to Shareholders - It is the policy of the Fund
to declare daily dividends from net investment income. Such dividends are
paid monthly. Net realized capital gains (including net short-term capital
gains and market discounts), if any, are distributed annually.
D. Federal Income Taxes - The Fund intends to comply with the requirements of
the Internal Revenue Code necessary to qualify as a regulated investment
company and, as such, will not be subject to federal income taxes on
otherwise taxable income (including net realized capital gains) which is
distributed to shareholders. Therefore, no provision for federal income
taxes is recorded in the financial statements. The Fund has a capital loss
carryforward of $85,975 (which may be carried forward to offset future
taxable gains, if any) which expires, if not previously utilized, through
the year 2004. The Fund cannot distribute capital gains to shareholders
until the tax loss carryforwards have been utilized. In addition, the Fund
intends to invest in sufficient municipal securities to allow it to qualify
to pay "exempt interest dividends," as defined in the Internal Revenue Code,
to shareholders.
E. Expenses - Distribution expenses directly attributable to a class of shares
are charged to that class' operations. All other expenses which are
attributable to more than one class are allocated between the classes.
NOTE 2 - ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES
The Company has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment advisory
agreement, the Fund pays an advisory fee to AIM at the annual rate of 0.25% of
the first $500 million of the Fund's average daily net assets plus 0.20% of the
Fund's average daily net assets in excess of $500 million.
AIM has voluntarily agreed to reduce its fee from the Fund to the extent
necessary so that the amount of ordinary expenses of the Institutional Shares
(excluding interest, taxes, brokerage commissions, directors' fees,
extraordinary expenses and federal registration fees) paid or incurred by the
Institutional Shares does not exceed 0.20% of the Institutional Shares' average
daily net assets. As a result, AIM's advisory fee on the Private Investment
Class is reduced in the same proportion as the Institutional Shares. For the
year ended March 31, 1998, AIM reduced its advisory fee from the Fund by
$683,910.
The Fund, pursuant to a master administrative services agreement with AIM, has
agreed to reimburse AIM for certain administrative costs incurred in providing
accounting services to the Fund. During the year ended March 31, 1998, the Fund
reimbursed AIM $66,515 for such services.

<PAGE>
Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Company, FMC acts as the exclusive distributor of
capital stock of the Institutional Shares and the Private Investment Class. The
Company has adopted a master distribution plan (the "Plan") pursuant to Rule
12b-1 under the 1940 Act with respect to the Private Investment Class. The Plan
provides that the Private Investment Class may pay up to a 0.50% maximum annual
rate of the Private Investment Class' average daily net assets. Of this amount,
the Fund may pay an asset-based sales charge to FMC and the Fund may pay a
service fee of 0.25% of the average daily net assets of the Private Investment
Class to selected broker-dealers and other financial institutions who offer
continuing personal shareholder services to their customers who purchase and
own shares of the Private Investment Class. Any amounts not paid as a service
fee under such Plan would constitute an asset-based sales charge. The Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Fund with respect to the Private Investment
Class. During the year ended March 31, 1998, the Private Investment Class paid
$135,349 as compensation to FMC under the Plan. FMC waived fees of $135,349
during the same period.
The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agent and
shareholder services to the Fund. On September 20, 1997, the Board of Directors
of the Fund approved appointment of AFS as transfer agent of the Fund effective
December 29, 1997. During the year ended March 31, 1998, the Fund paid AFS
$25,471 for such services. Prior to effective date of the agreement with AFS,
the Fund paid A I M Institutional Fund Services, Inc. $74,497 pursuant to a
transfer agency and shareholder services agreement for the period April 1, 1997
through December 28, 1997.
During the year ended March 31, 1998, the Fund paid legal fees of $4,852 for
services rendered by Kramer, Levin, Naftalis & Frankel as counsel to the Board
of Directors. A member of that firm is a director of the Company.
NOTE 3 - DIRECTORS' FEES
Directors' fees represent remuneration paid or accrued to each director who is
not an "interested person" of AIM. The Company may invest directors' fees, if
so elected by a director, in mutual fund shares in accordance with a deferred
compensation plan.
NOTE 4 - CAPITAL STOCK
Changes in capital stock outstanding during the years ended March 31, 1998 and

INDEPENDENT AUDITORS' REPORT
To the Board of Directors and Shareholders
Tax-Free Investments Co.:
We have audited the accompanying statement of assets and liabilities of the
Cash Reserve Portfolio (a Portfolio of Tax-Free Investments Co.), including the
schedule of investments, as of March 31, 1998, and the related statement of
operations for the year then ended, the statement 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 five-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 the financial highlights. Our procedures included confirmation
of securities owned as of March 31, 1998, 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 the
Cash Reserve Portfolio as of March 31, 1998, 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 five-year period then ended, in conformity with generally accepted
accounting principles.
