TAX-FREE CASH RESERVE PORTFOLIO

                   DEAR SHAREHOLDER:

                   We are pleased to present this report on the performance of
                   the Cash Management Class of Tax-Free Cash Reserve Portfolio
    [GRAHAM        of Tax-Free Investments Trust, part of AIM Cash Management,
     PHOTO]        covering the fiscal year ended March 31, 2006. Thank you for
                   investing with us.

                      Tax-Free Cash Reserve Portfolio seeks to provide as high a
 ROBERT H. GRAHAM  level of tax-exempt income as is consistent with preservation
                   of capital and maintenance of liquidity. The Fund invests in
                   high-quality, short-term municipal obligations, seeking to
                   provide income exempt from federal taxation. The Fund
                   structure is driven to some extent by the supply of municipal
                   securities. Liquidity is managed with daily and weekly
                   variable-rate demand notes.

   Through a combination of short-term cash management vehicles and selective
use of a longer maturity schedule for higher yields, the Fund continued to
provide competitive returns. The Fund maintained a relatively short maturity
structure to take advantage of any sudden rise in market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o Gross domestic product, generally considered the broadest measure of
     overall economic activity, grew at an annualized rate of 3.5% in 2005, and
     4.8% in the first quarter of 2006

   o In response to the Fed's actions, short-term yields rose steadily during
     the year covered by this report. Longer term yields did not, creating a
     flattening of the yield curve

   o Led by strong refunding activity in anticipation of higher interest
     rates, total municipal securities issuance set a record in calendar year
     2005, according to the Bond Market Association. Fed tightening caused
     short-term issuance to decline from 2004 to 2005, however

TAX-FREE CASH RESERVE PORTFOLIO


                   DEAR FELLOW AIM FUND SHAREHOLDERS:

                   Having completed a year of transition and change at AIM
                   Funds--as well as my first full year as your board's
   [CROCKETT       independent chair--I can assure you that shareholder
     PHOTO]        interests are at the forefront of every decision your board
                   makes. While regulators and fund companies debate the value
   BRUCE L.        of an independent board chair, this structure is working for
   CROCKETT        you. Our new structure has enabled the board to work more
                   effectively with management to achieve benefits for the
                   shareholders, as shown in the highlights of 2005 listed
                   below:

                      o During 2005, management proposed, and your board
                        approved, voluntary advisory fee reductions, which are
                        saving shareholders more than $20 million annually,
                        based on asset levels of March 31, 2005.

                      o Also during 2005, management proposed to your board the
                        merger of 14 funds into other AIM funds with similar
                        objectives. In each case, the goal was for the resulting
                        merged fund to benefit from strengthened management and
                        greater efficiency. Your board carefully analyzed and
                        discussed with management the rationale and proposed
                        terms of each merger to ensure that the mergers were
                        beneficial to the shareholders of all affected funds
                        before approving them. Eight of these mergers were
                        subsequently approved by shareholders of the target
                        funds during 2005. The remaining six fund mergers were
                        approved by shareholders in early 2006.

                      o Your board, through its Investments Committee and
                        Subcommittees, continued to closely monitor the
                        portfolio performance of the funds. During the year,
                        your board reviewed portfolio management changes made by
                        the advisor at 11 funds with the objective of organizing
                        management teams around common processes and shared
                        investment views. Management believes these changes will
                        lead to improved investment performance.

                      In 2006, your board will continue to focus on fund
                   expenses and investment performance. Although many funds have
                   good performance, we are working with management to seek
                   improvements for those funds currently performing below
                   expectations. Eight in-person board meetings and several
                   additional telephone and committee meetings are scheduled to
                   take place this year. I'll inform you of our progress in my
                   next semiannual letter to shareholders.

                      The AIM Funds board is pleased to welcome our newest
                   independent member, Raymond Stickel, Jr., a former partner
                   with the international auditing firm of Deloitte & Touche. We
                   also send our thanks and best wishes to Gerald J. Lewis, who
                   retired from your board in December 2005, and to Edward K.
                   Dunn, Jr., who retired in 2006.

                      Your board welcomes your views. Please mail them to me at
                   AIM Investments, AIM Investments Tower, 11 Greenway Plaza,

Notes to Schedule of Investments:

(a) Ratings assigned by Standard & Poor's Corporation ("S&P") and Moody's
    Investors Service, Inc. ("Moody's"), except as indicated in notes (j) and
    (r) below. NRR indicates a security that is not re-rated subsequent to
    funding of an escrow fund (consisting of U.S. Government obligations held by
    a bank custodian); this funding is pursuant to an advance refunding of this
    security. Ratings are not covered by the Report of Independent Registered
    Public Accounting Firm.
(b) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined
    weekly. Rate shown is the rate in effect on March 31, 2006.
(c) Principal and interest payments are fully enhanced by a letter of credit
    from the bank listed or a predecessor bank, branch or subsidiary.
(d) Demand security payable upon demand by the Fund at specified time intervals
    no greater than one business day's notice. Interest rate is redetermined
    daily. Rate shown is the rate in effect on March 31, 2006.
(e) Principal and/or interest payments are secured by the bond insurance company
    listed.
(f) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined
    monthly. Rate shown is the rate in effect on March 31, 2006.
(g) The security is credit guaranteed, enhanced or has credit risk by a foreign
    entity. No concentration of any single foreign country was greater than 5%.
(h) Synthetic municipal instruments; involves the deposit into a trust of one or
    more long-term tax-exempt bonds or notes ("Underlying Bonds."), a sale of
    certificates evidencing interests in the trust to investors such as the
    Fund. The trustee receives the long-term fixed interest payments on the
    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.
(i) Security not registered under the Securities Act of 1933, as amended (e.g.,
    the security was purchased in a Rule 144A transaction or a Regulation D
    transaction). The security may be resold only pursuant to an exemption from
    registration under the 1933 Act, typically to qualified institutional
    buyers. The Fund has no rights to demand registration of these securities.
    The aggregate value of these securities at March 31, 2006 was $901,459,500,
    which represented 28.29% of the Fund's Net Assets. Unless otherwise
    indicated, these securities are not considered to be illiquid.

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Cash Management Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Cash Management Class financial highlights for the year
then ended, in conformity with accounting principles generally accepted in the
United States of America. These financial statements and Cash Management Class
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Cash
Management Class financial highlights for each of the periods ended on or before
March 31, 2005 were audited by another independent registered public accounting
firm whose report dated May 18, 2005 expressed an unqualified opinion on those
statements.

TAX-FREE CASH RESERVE PORTFOLIO


                   DEAR SHAREHOLDER:

                   We are pleased to present this report on the performance of
                   the Corporate Class of Tax-Free Cash Reserve Portfolio of
    [GRAHAM        Tax-Free Investments Trust, part of AIM Cash Management,
     PHOTO]        covering the fiscal year ended March 31, 2006. Thank you for
                   investing with us.

                      Tax-Free Cash Reserve Portfolio seeks to provide as high a
 ROBERT H. GRAHAM  level of tax-exempt income as is consistent with preservation
                   of capital and maintenance of liquidity. The Fund invests in
                   high-quality, short-term municipal obligations, seeking to
                   provide income exempt from federal taxation. The Fund
                   structure is driven to some extent by the supply of municipal
                   securities. Liquidity is managed with daily and weekly
                   variable-rate demand notes.

   Through a combination of short-term cash management vehicles and selective
use of a longer maturity schedule for higher yields, the Fund continued to
provide competitive returns. The Fund maintained a relatively short maturity
structure to take advantage of any sudden rise in market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

TAX-FREE CASH RESERVE PORTFOLIO

                   DEAR FELLOW AIM FUND SHAREHOLDERS:

                   Having completed a year of transition and change at AIM
                   Funds--as well as my first full year as your board's
    [CROCKETT      independent chair--I can assure you that shareholder
      PHOTO]       interests are at the forefront of every decision your board
                   makes. While regulators and fund companies debate the value
                   of an independent board chair, this structure is working for
                   you. Our new structure has enabled the board to work more
                   effectively with management to achieve benefits for the
BRUCE L. CROCKETT  shareholders, as shown in the highlights of 2005 listed
                   below:

                      o During 2005, management proposed, and your board
                        approved, voluntary advisory fee reductions, which are
                        saving shareholders more than $20 million annually,
                        based on asset levels of March 31, 2005.

                      o Also during 2005, management proposed to your board the
                        merger of 14 funds into other AIM funds with similar
                        objectives. In each case, the goal was for the resulting
                        merged fund to benefit from strengthened management and
                        greater efficiency. Your board carefully analyzed and
                        discussed with management the rationale and proposed
                        terms of each merger to ensure that the mergers were
                        beneficial to the shareholders of all affected funds
                        before approving them. Eight of these mergers were
                        subsequently approved by shareholders of the target
                        funds during 2005. The remaining six fund mergers were
                        approved by shareholders in early 2006.

                      o Your board, through its Investments Committee and
                        Subcommittees, continued to closely monitor the
                        portfolio performance of the funds. During the year,
                        your board reviewed portfolio management changes made by
                        the advisor at 11 funds with the objective of organizing
                        management teams around common processes and shared
                        investment views. Management believes these changes will
                        lead to improved investment performance.

                      In 2006, your board will continue to focus on fund
                   expenses and investment performance. Although many funds have
                   good performance, we are working with management to seek
                   improvements for those funds currently performing below
                   expectations. Eight in-person board meetings and several
                   additional telephone and committee meetings are scheduled to
                   take place this year. I'll inform you of our progress in my
                   next semiannual letter to shareholders.

                      The AIM Funds board is pleased to welcome our newest
                   independent member, Raymond Stickel, Jr., a former partner
                   with the international auditing firm of Deloitte & Touche. We
                   also send our thanks and best wishes to Gerald J. Lewis, who
                   retired from your board in December 2005, and to Edward K.

    Public Accounting Firm.

    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.
(i) Security not registered under the Securities Act of 1933, as amended (e.g.,
    the security was purchased in a Rule 144A transaction or a Regulation D

    buyers. The Fund has no rights to demand registration of these securities.
    The aggregate value of these securities at March 31, 2006 was $901,459,500,
    which represented 28.29% of the Fund's Net Assets. Unless otherwise

    IBCA ("Fitch") of F1(+).

    investments are through participation in joint accounts with other mutual
    funds, private accounts and certain non-registered investment companies
    managed by the investment advisor or its affiliates.
(p) Security considered to be illiquid. The Fund is limited to investing 10% of
    net assets in illiquid securities at the time of purchase. The aggregate

    guaranteed, backed or otherwise enhanced the credit quality of more than 5%
    of the securities held in the portfolio. In instances where the entity has

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

                                       F-33


TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

NOTE 6--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS

book/tax differences are the result of the trustee deferral of compensation and
retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Corporate Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Corporate Class financial highlights for the year then
ended, in conformity with accounting principles generally accepted in the United
States of America. These financial statements and Corporate Class financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Corporate
Class financial highlights for each of the periods ended on or before March 31,
2005 were audited by another independent registered public accounting firm whose
report dated May 18, 2005 expressed an unqualified opinion on those statements.

TAX-FREE CASH RESERVE PORTFOLIO


                   DEAR SHAREHOLDER:

                   We are pleased to present this report on the performance of
                   the Institutional Class of Tax-Free Cash Reserve Portfolio of
   [GRAHAM         Tax-Free Investments Trust, part of AIM Cash Management,
    PHOTO]         covering the fiscal year ended March 31, 2006. Thank you for
                   investing with us.

                      Tax-Free Cash Reserve Portfolio seeks to provide as high a
 ROBERT H. GRAHAM  level of tax-exempt income as is consistent with preservation
                   of capital and maintenance of liquidity. The Fund invests in
                   high-quality, short-term municipal obligations, seeking to
                   provide income exempt from federal taxation. The Fund
                   structure is driven to some extent by the supply of municipal
                   securities. Liquidity is managed with daily and weekly
                   variable-rate demand notes.

   Through a combination of short-term cash management vehicles and selective
use of a longer maturity schedule for higher yields, the Fund continued to
provide competitive returns. The Fund maintained a relatively short maturity
structure to take advantage of any sudden rise in market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

                   DEAR FELLOW AIM FUND SHAREHOLDERS:

                   Having completed a year of transition and change at AIM
                   Funds--as well as my first full year as your board's
    [CROCKETT      independent chair--I can assure you that shareholder
      PHOTO]       interests are at the forefront of every decision your board
                   makes. While regulators and fund companies debate the value
                   of an independent board chair, this structure is working for
                   you. Our new structure has enabled the board to work more
                   effectively with management to achieve benefits for the
BRUCE L. CROCKETT  shareholders, as shown in the highlights of 2005 listed
                   below:

                      o During 2005, management proposed, and your board
                        approved, voluntary advisory fee reductions, which are
                        saving shareholders more than $20 million annually,
                        based on asset levels of March 31, 2005.

                      o Also during 2005, management proposed to your board the
                        merger of 14 funds into other AIM funds with similar
                        objectives. In each case, the goal was for the resulting
                        merged fund to benefit from strengthened management and
                        greater efficiency. Your board carefully analyzed and
                        discussed with management the rationale and proposed
                        terms of each merger to ensure that the mergers were
                        beneficial to the shareholders of all affected funds
                        before approving them. Eight of these mergers were
                        subsequently approved by shareholders of the target
                        funds during 2005. The remaining six fund mergers were
                        approved by shareholders in early 2006.

                      o Your board, through its Investments Committee and
                        Subcommittees, continued to closely monitor the
                        portfolio performance of the funds. During the year,
                        your board reviewed portfolio management changes made by
                        the advisor at 11 funds with the objective of organizing
                        management teams around common processes and shared
                        investment views. Management believes these changes will
                        lead to improved investment performance.

                      In 2006, your board will continue to focus on fund
                   expenses and investment performance. Although many funds have
                   good performance, we are working with management to seek
                   improvements for those funds currently performing below
                   expectations. Eight in-person board meetings and several
                   additional telephone and committee meetings are scheduled to
                   take place this year. I'll inform you of our progress in my
                   next semiannual letter to shareholders.

                      The AIM Funds board is pleased to welcome our newest
                   independent member, Raymond Stickel, Jr., a former partner
                   with the international auditing firm of Deloitte & Touche. We
                   also send our thanks and best wishes to Gerald J. Lewis, who
                   retired from your board in December 2005, and to Edward K.
                   Dunn, Jr., who retired in 2006.

                      Your board welcomes your views. Please mail them to me at
                   AIM Investments, AIM Investments Tower, 11 Greenway Plaza,
                   Suite 100, Houston TX 77046.

                   Sincerely,

                   /S/ BRUCE L. CROCKETT

                   Bruce L. Crockett

    security. Ratings are not covered by the Report of Independent Registered
    Public Accounting Firm.
(b) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined

    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.
(i) Security not registered under the Securities Act of 1933, as amended (e.g.,
    the security was purchased in a Rule 144A transaction or a Regulation D

    registration under the 1933 Act, typically to qualified institutional
    buyers. The Fund has no rights to demand registration of these securities.
    The aggregate value of these securities at March 31, 2006 was $901,459,500,
    which represented 28.29% of the Fund's Net Assets. Unless otherwise
    indicated, these securities are not considered to be illiquid.
(j) Security is not rated by S&P or by Moody's; however it is rated by Fitch
    IBCA ("Fitch") of F1(+).
(k) Security has an irrevocable call by the issuer or mandatory put by the
    holder. Maturity date reflects such call or put.
(l) Demand security payable upon demand by the Fund at specified time intervals
    no greater than thirteen months. Interest rate is redetermined at
    intermittent intervals. Rate shown is the rate in effect on March 31, 2006.

    investments are through participation in joint accounts with other mutual
    funds, private accounts and certain non-registered investment companies
    managed by the investment advisor or its affiliates.
(p) Security considered to be illiquid. The Fund is limited to investing 10% of
    net assets in illiquid securities at the time of purchase. The aggregate
    value of these securities considered illiquid at March 31, 2006 was

    quality to the rated securities in which the Fund may invest pursuant to

    guaranteed, backed or otherwise enhanced the credit quality of more than 5%
    of the securities held in the portfolio. In instances where the entity has

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

NOTE 6--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS

    The temporary book/tax differences are a result of timing differences
between book and tax recognition of income and/or expenses. The Fund's temporary
book/tax differences are the result of the trustee deferral of compensation and
retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

TAX-FREE INVESTMENTS TRUST

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Institutional Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Institutional Class financial highlights for the year
then ended, in conformity with accounting principles generally accepted in the
United States of America. These financial statements and Institutional Class
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the
Institutional Class financial highlights for each of the periods ended on or
before March 31, 2005 were audited by another independent registered public
accounting firm whose report dated May 18, 2005 expressed an unqualified opinion
on those statements.

TAX-FREE CASH RESERVE PORTFOLIO


                    DEAR SHAREHOLDER:

                    We are pleased to present this report on the performance of
    [GRAHAM         the Personal Investment Class of Tax-Free Cash Reserve
     PHOTO]         Portfolio of Tax-Free Investments Trust, part of AIM Cash
                    Management, covering the fiscal year ended March 31, 2006.
                    Thank you for investing with us.

                       Tax-Free Cash Reserve Portfolio seeks to provide as high
                    a level of tax-exempt income as is consistent with
 ROBERT H. GRAHAM   preservation of capital and maintenance of liquidity. The
                    Fund invests in high-quality, short-term municipal
                    obligations, seeking to provide income exempt from federal
                    taxation. The Fund structure is driven to some extent by the
                    supply of municipal securities. Liquidity is managed with
                    daily and weekly variable-rate demand notes.

                       Through a combination of short-term cash management
                    vehicles and selective use of a longer maturity schedule for
higher yields, the Fund continued to provide competitive returns. The Fund
maintained a relatively short maturity structure to take advantage of any sudden
rise in market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

TAX-FREE CASH RESERVE PORTFOLIO


                    DEAR FELLOW AIM FUND SHAREHOLDERS:

                    Having completed a year of transition and change at AIM
                    Funds--as well as my first full year as your board's
   [CROCKETT        independent chair--I can assure you that shareholder
     PHOTO]         interests are at the forefront of every decision your board
                    makes. While regulators and fund companies debate the value
                    of an independent board chair, this structure is working for
                    you. Our new structure has enabled the board to work more
BRUCE L. CROCKETT   effectively with management to achieve benefits for the
                    shareholders, as shown in the highlights of 2005 listed
                    below:

                       o  During 2005, management proposed, and your board
                          approved, voluntary advisory fee reductions, which are
                          saving shareholders more than $20 million annually,
                          based on asset levels of March 31, 2005.

                       o  Also during 2005, management proposed to your board
                          the merger of 14 funds into other AIM funds with
                          similar objectives. In each case, the goal was for the
                          resulting merged fund to benefit from strengthened
                          management and greater efficiency. Your board
                          carefully analyzed and discussed with management the
                          rationale and proposed terms of each merger to ensure
                          that the mergers were beneficial to the shareholders
                          of all affected funds before approving them. Eight of
                          these mergers were subsequently approved by
                          shareholders of the target funds during 2005. The
                          remaining six fund mergers were approved by
                          shareholders in early 2006.

                       o  Your board, through its Investments Committee and
                          Subcommittees, continued to closely monitor the
                          portfolio performance of the funds. During the year,
                          your board reviewed portfolio management changes made
                          by the advisor at 11 funds with the objective of
                          organizing management teams around common processes
                          and shared investment views. Management believes these
                          changes will lead to improved investment performance.

                       In 2006, your board will continue to focus on fund
                    expenses and investment performance. Although many funds
                    have good performance, we are working with management to
                    seek improvements for those funds currently performing below
                    expectations. Eight in-person board meetings and several
                    additional telephone and committee meetings are scheduled to
                    take place this year. I'll inform you of our progress in my
                    next semiannual letter to shareholders.

                       The AIM Funds board is pleased to welcome our newest
                    independent member, Raymond Stickel, Jr., a former partner
                    with the international auditing firm of Deloitte & Touche.
                    We also send our thanks and best wishes to Gerald J. Lewis,
                    who retired from your board in December 2005, and to Edward
                    K. Dunn, Jr., who retired in 2006.

                       Your board welcomes your views. Please mail them to me at
                    AIM Investments, AIM Investments Tower, 11 Greenway Plaza,

    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.

    investments are through participation in joint accounts with other mutual
    funds, private accounts and certain non-registered investment companies
    managed by the investment advisor or its affiliates.
(p) Security considered to be illiquid. The Fund is limited to investing 10% of
    net assets in illiquid securities at the time of purchase. The aggregate

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Personal Investment Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Personal Investment Class financial highlights for the
year then ended, in conformity with accounting principles generally accepted in
the United States of America. These financial statements and Personal Investment
Class financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Personal
Investment Class financial highlights for each of the periods ended on or before
March 31, 2005 were audited by another independent registered public accounting
firm whose report dated May 18, 2005 expressed an unqualified opinion on those
statements.

TAX-FREE CASH RESERVE PORTFOLIO

                    DEAR SHAREHOLDER:

                    We are pleased to present this report on the performance of
                    the Private Investment Class of Tax-Free Cash Reserve
   [GRAHAM          Portfolio of Tax-Free Investments Trust, part of AIM Cash
    PHOTO]          Management, covering the fiscal year ended March 31, 2006.
                    Thank you for investing with us.

                       Tax-Free Cash Reserve Portfolio seeks to provide as high
                    a level of tax-exempt income as is consistent with
                    preservation of capital and maintenance of liquidity. The
 ROBERT H. GRAHAM   Fund invests in high-quality, short-term municipal
                    obligations, seeking to provide income exempt from federal
                    taxation. The Fund structure is driven to some extent by the
                    supply of municipal securities. Liquidity is managed with
                    daily and weekly variable-rate demand notes.

                       Through a combination of short-term cash management
                    vehicles and selective use of a longer maturity schedule for
                    higher yields, the Fund continued to provide competitive
                    returns. The Fund maintained a relatively short maturity
                    structure to take advantage of any sudden rise in market
                    yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

TAX-FREE CASH RESERVE PORTFOLIO

                    DEAR FELLOW AIM FUND SHAREHOLDERS:

                    Having completed a year of transition and change at AIM
                    Funds--as well as my first full year as your board's
   [CROCKETT        independent chair--I can assure you that shareholder
     PHOTO]         interests are at the forefront of every decision your board
                    makes. While regulators and fund companies debate the value
                    of an independent board chair, this structure is working for
                    you. Our new structure has enabled the board to work more
 BRUCE L. CROCKETT  effectively with management to achieve benefits for the
                    shareholders, as shown in the highlights of 2005 listed
                    below:

                       o  During 2005, management proposed, and your board
                          approved, voluntary advisory fee reductions, which are
                          saving shareholders more than $20 million annually,
                          based on asset levels of March 31, 2005.

                       o  Also during 2005, management proposed to your board
                          the merger of 14 funds into other AIM funds with
                          similar objectives. In each case, the goal was for the
                          resulting merged fund to benefit from strengthened
                          management and greater efficiency. Your board
                          carefully analyzed and discussed with management the
                          rationale and proposed terms of each merger to ensure
                          that the mergers were beneficial to the shareholders
                          of all affected funds before approving them. Eight of
                          these mergers were subsequently approved by
                          shareholders of the target funds during 2005. The
                          remaining six fund mergers were approved by
                          shareholders in early 2006.

                       o  Your board, through its Investments Committee and
                          Subcommittees, continued to closely monitor the
                          portfolio performance of the funds. During the year,
                          your board reviewed portfolio management changes made
                          by the advisor at 11 funds with the objective of
                          organizing management teams around common processes
                          and shared investment views. Management believes these
                          changes will lead to improved investment performance.

                       In 2006, your board will continue to focus on fund
                    expenses and investment performance. Although many funds
                    have good performance, we are working with management to
                    seek improvements for those funds currently performing below
                    expectations. Eight in-person board meetings and several
                    additional telephone and committee meetings are scheduled to
                    take place this year. I'll inform you of our progress in my
                    next semiannual letter to shareholders.

                       The AIM Funds board is pleased to welcome our newest
                    independent member, Raymond Stickel, Jr., a former partner
                    with the international auditing firm of Deloitte & Touche.
                    We also send our thanks and best wishes to Gerald J. Lewis,
                    who retired from your board in December 2005, and to Edward
                    K. Dunn, Jr., who retired in 2006.

                       Your board welcomes your views. Please mail them to me at

    Public Accounting Firm.

    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.

    investments are through participation in joint accounts with other mutual
    funds, private accounts and certain non-registered investment companies
    managed by the investment advisor or its affiliates.

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

                                       F-33


TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

NOTE 6--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS

retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Private Investment Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Private Investment Class financial highlights for the
year then ended, in conformity with accounting principles generally accepted in
the United States of America. These financial statements and Private Investment
Class financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Private
Investment Class financial highlights for each of the periods ended on or before
March 31, 2005 were audited by another independent registered public accounting
firm whose report dated May 18, 2005 expressed an unqualified opinion on those
statements.

TAX-FREE CASH RESERVE PORTFOLIO

                    DEAR SHAREHOLDER:

                    We are pleased to present this report on the performance of
    [GRAHAM         the Reserve Class of Tax-Free Cash Reserve Portfolio of
     PHOTO]         Tax-Free Investments Trust, part of AIM Cash Management,
                    covering the fiscal year ended March 31, 2006. Thank you for
                    investing with us.

                       Tax-Free Cash Reserve Portfolio seeks to provide as high
 ROBERT H. GRAHAM   a level of tax-exempt income as is consistent with
                    preservation of capital and maintenance of liquidity. The
                    Fund invests in high-quality, short-term municipal
                    obligations, seeking to provide income exempt from federal
                    taxation. The Fund structure is driven to some extent by the
                    supply of municipal securities. Liquidity is managed with
                    daily and weekly variable-rate demand notes.

                       Through a combination of short-term cash management
                    vehicles and selective use of a longer maturity schedule
                    for higher yields, the Fund continued to provide
                    competitive returns. The Fund maintained a relatively short
                    maturity structure to take advantage of any sudden rise in
                    market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

                    DEAR FELLOW AIM FUND SHAREHOLDERS:

                    Having completed a year of transition and change at AIM
    [CROCKETT       Funds--as well as my first full year as your board's
      PHOTO]        independent chair--I can assure you that shareholder
                    interests are at the forefront of every decision your board
                    makes. While regulators and fund companies debate the value
                    of an independent board chair, this structure is working for
                    you. Our new structure has enabled the board to work more
 BRUCE L. CROCKETT  effectively with management to achieve benefits for the
                    shareholders, as shown in the highlights of 2005 listed
                    below:

                       o  During 2005, management proposed, and your board
                          approved, voluntary advisory fee reductions, which are
                          saving shareholders more than $20 million annually,
                          based on asset levels of March 31, 2005.

                       o  Also during 2005, management proposed to your board
                          the merger of 14 funds into other AIM funds with
                          similar objectives. In each case, the goal was for the
                          resulting merged fund to benefit from strengthened
                          management and greater efficiency. Your board
                          carefully analyzed and discussed with management the
                          rationale and proposed terms of each merger to ensure
                          that the mergers were beneficial to the shareholders
                          of all affected funds before approving them. Eight of
                          these mergers were subsequently approved by
                          shareholders of the target funds during 2005. The
                          remaining six fund mergers were approved by
                          shareholders in early 2006.

                       o  Your board, through its Investments Committee and
                          Subcommittees, continued to closely monitor the
                          portfolio performance of the funds. During the year,
                          your board reviewed portfolio management changes made
                          by the advisor at 11 funds with the objective of
                          organizing management teams around common processes
                          and shared investment views. Management believes these
                          changes will lead to improved investment performance.

                       In 2006, your board will continue to focus on fund
                    expenses and investment performance. Although many funds
                    have good performance, we are working with management to
                    seek improvements for those funds currently performing below
                    expectations. Eight in-person board meetings and several
                    additional telephone and committee meetings are scheduled to
                    take place this year. I'll inform you of our progress in my
                    next semiannual letter to shareholders.

                       The AIM Funds board is pleased to welcome our newest
                    independent member, Raymond Stickel, Jr., a former partner
                    with the international auditing firm of Deloitte & Touche.
                    We also send our thanks and best wishes to Gerald J. Lewis,
                    who retired from your board in December 2005, and to Edward
                    K. Dunn, Jr., who retired in 2006.

                       Your board welcomes your views. Please mail them to me at
                    AIM Investments, AIM Investments Tower, 11 Greenway Plaza,
                    Suite 100, Houston TX 77046.


                    Sincerely,


                    /S/ BRUCE L. CROCKETT

    a bank custodian); this funding is pursuant to an advance refunding of this
    security. Ratings are not covered by the Report of Independent Registered
    Public Accounting Firm.
(b) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined
    weekly. Rate shown is the rate in effect on March 31, 2006.

    certificates evidencing interests in the trust to investors such as the

    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.
(i) Security not registered under the Securities Act of 1933, as amended (e.g.,
    the security was purchased in a Rule 144A transaction or a Regulation D

    registration under the 1933 Act, typically to qualified institutional
    buyers. The Fund has no rights to demand registration of these securities.
    The aggregate value of these securities at March 31, 2006 was $901,459,500,
    which represented 28.29% of the Fund's Net Assets. Unless otherwise
    indicated, these securities are not considered to be illiquid.
(j) Security is not rated by S&P or by Moody's; however it is rated by Fitch
    IBCA ("Fitch") of F1(+).
(k) Security has an irrevocable call by the issuer or mandatory put by the
    holder. Maturity date reflects such call or put.
(l) Demand security payable upon demand by the Fund at specified time intervals
    no greater than thirteen months. Interest rate is redetermined at
    intermittent intervals. Rate shown is the rate in effect on March 31, 2006.

    semi-annually. Rate shown is the rate in effect on March 31, 2006.
(n) Demand security payable upon demand by the Fund at specified time intervals
    no greater than thirteen months. Interest rate is redetermined annually.
    Rate shown is the rate in effect on March 31, 2006.
(o) In accordance with the procedures established by the Board of Trustees,
    investments are through participation in joint accounts with other mutual
    funds, private accounts and certain non-registered investment companies
    managed by the investment advisor or its affiliates.
(p) Security considered to be illiquid. The Fund is limited to investing 10% of
    net assets in illiquid securities at the time of purchase. The aggregate
    value of these securities considered illiquid at March 31, 2006 was
    $43,660,000, which represented 1.37% of the Fund's Net Assets.
(q) Advance refunded; secured by an escrow fund of U.S. Government obligations.

    quality to the rated securities in which the Fund may invest pursuant to

    guaranteed, backed or otherwise enhanced the credit quality of more than 5%
    of the securities held in the portfolio. In instances where the entity has
    guaranteed, backed or otherwise enhanced the credit quality of a security,
    it is not primarily responsible for the issuer's obligations but may be
    called upon to satisfy the issuer's obligations.

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

                                       F-33


TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

NOTE 6--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS

DISTRIBUTIONS TO SHAREHOLDERS:

    The temporary book/tax differences are a result of timing differences
between book and tax recognition of income and/or expenses. The Fund's temporary
book/tax differences are the result of the trustee deferral of compensation and
retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

TAX-FREE INVESTMENTS TRUST

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Reserve Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Reserve Class financial highlights for the year then
ended, in conformity with accounting principles generally accepted in the United
States of America. These financial statements and Reserve Class financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Reserve
Class financial highlights for each of the periods ended on or before March 31,
2005 were audited by another independent registered public accounting firm whose
report dated May 18, 2005 expressed an unqualified opinion on those statements.

TAX-FREE CASH RESERVE PORTFOLIO


                    DEAR SHAREHOLDER:

                    We are pleased to present this report on the performance of
                    the Resource Class of Tax-Free Cash Reserve Portfolio of
    [GRAHAM         Tax-Free Investments Trust, part of AIM Cash Management,
     PHOTO]         covering the fiscal year ended March 31, 2006. Thank you for
                    investing with us.

                       Tax-Free Cash Reserve Portfolio seeks to provide as high
 ROBERT H. GRAHAM   a level of tax-exempt income as is consistent with
                    preservation of capital and maintenance of liquidity. The
                    Fund invests in high-quality, short-term municipal
                    obligations, seeking to provide income exempt from federal
                    taxation. The Fund structure is driven to some extent by the
                    supply of municipal securities. Liquidity is managed with
                    daily and weekly variable-rate demand notes.

   Through a combination of short-term cash management vehicles and selective
use of a longer maturity schedule for higher yields, the Fund continued to
provide competitive returns. The Fund maintained a relatively short maturity
structure to take advantage of any sudden rise in market yields.

   The Fund continued to hold the highest credit-quality ratings given by three
widely known credit rating agencies: AAAm from Standard & Poor's, Aaa from
Moody's and AAA from FitchRatings. Fund ratings are subject to change and are
based on several factors, including an analysis of the Fund's overall credit
quality, market price exposure and management.

MARKET CONDITIONS AFFECTING MONEY MARKET FUNDS

The economy continued to expand at a moderate pace throughout the fiscal year
ended March 31, 2006. In an effort to foster economic growth and prevent
inflation, the U.S. Federal Reserve Board (the Fed) slowly but steadily raised
its federal funds target rate. The federal funds rate is the interest rate at
which depository institutions lend money overnight to one another from their
Federal Reserve balances.

   The Fed raised this key interest rate by 25 basis points (0.25%) eight times,
increasing it from 2.75% at the start of the fiscal year to 4.75% at its close.
As the fiscal year-end approached, there was widespread expectation that the Fed
was nearing an end to its tightening cycle.

   Money market funds were also affected by these factors and trends:

   o  Gross domestic product, generally considered the broadest measure of
      overall economic activity, grew at an annualized rate of 3.5% in 2005, and
      4.8% in the first quarter of 2006

   o  In response to the Fed's actions, short-term yields rose steadily during
      the year covered by this report. Longer term yields did not, creating a
      flattening of the yield curve

   o  Led by strong refunding activity in anticipation of higher interest rates,
      total municipal securities issuance set a record in calendar year 2005,
      according to the Bond Market Association. Fed tightening caused short-term
      issuance to decline from 2004 to 2005, however

TAX-FREE CASH RESERVE PORTFOLIO

                    DEAR FELLOW AIM FUND SHAREHOLDERS:

                    Having completed a year of transition and change at AIM
                    Funds--as well as my first full year as your board's
   [CROCKETT        independent chair--I can assure you that shareholder
     PHOTO]         interests are at the forefront of every decision your board
                    makes. While regulators and fund companies debate the value
                    of an independent board chair, this structure is working for
                    you. Our new structure has enabled the board to work more
BRUCE L. CROCKETT   effectively with management to achieve benefits for the
                    shareholders, as shown in the highlights of 2005 listed
                    below:

                    o  During 2005, management proposed, and your board
                       approved, voluntary advisory fee reductions, which are
                       saving shareholders more than $20 million annually, based
                       on asset levels of March 31, 2005.

                    o  Also during 2005, management proposed to your board the
                       merger of 14 funds into other AIM funds with similar
                       objectives. In each case, the goal was for the resulting
                       merged fund to benefit from strengthened management and
                       greater efficiency. Your board carefully analyzed and
                       discussed with management the rationale and proposed
                       terms of each merger to ensure that the mergers were
                       beneficial to the shareholders of all affected funds
                       before approving them. Eight of these mergers were
                       subsequently approved by shareholders of the target funds
                       during 2005. The remaining six fund mergers were approved
                       by shareholders in early 2006.

                    o  Your board, through its Investments Committee and
                       Subcommittees, continued to closely monitor the portfolio
                       performance of the funds. During the year, your board
                       reviewed portfolio management changes made by the advisor
                       at 11 funds with the objective of organizing management
                       teams around common processes and shared investment
                       views. Management believes these changes will lead to
                       improved investment performance.

                       In 2006, your board will continue to focus on fund
                    expenses and investment performance. Although many funds
                    have good performance, we are working with management to
                    seek improvements for those funds currently performing below
                    expectations. Eight in-person board meetings and several
                    additional telephone and committee meetings are scheduled to
                    take place this year. I'll inform you of our progress in my
                    next semiannual letter to shareholders.

                       The AIM Funds board is pleased to welcome our newest
                    independent member, Raymond Stickel, Jr., a former partner
                    with the international auditing firm of Deloitte & Touche.
                    We also send our thanks and best wishes to Gerald J. Lewis,
                    who retired from your board in December 2005, and to Edward
                    K. Dunn, Jr., who retired in 2006.

                       Your board welcomes your views. Please mail them to me at
                    AIM Investments, AIM Investments Tower, 11 Greenway Plaza,

Notes to Schedule of Investments:

(a) Ratings assigned by Standard & Poor's Corporation ("S&P") and Moody's
    Investors Service, Inc. ("Moody's"), except as indicated in notes (j) and
    (r) below. NRR indicates a security that is not re-rated subsequent to
    funding of an escrow fund (consisting of U.S. Government obligations held by
    a bank custodian); this funding is pursuant to an advance refunding of this
    security. Ratings are not covered by the Report of Independent Registered
    Public Accounting Firm.
(b) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined
    weekly. Rate shown is the rate in effect on March 31, 2006.
(c) Principal and interest payments are fully enhanced by a letter of credit
    from the bank listed or a predecessor bank, branch or subsidiary.
(d) Demand security payable upon demand by the Fund at specified time intervals
    no greater than one business day's notice. Interest rate is redetermined
    daily. Rate shown is the rate in effect on March 31, 2006.
(e) Principal and/or interest payments are secured by the bond insurance company
    listed.
(f) Demand security payable upon demand by the Fund at specified time intervals
    no greater than seven calendar days' notice. Interest rate is redetermined
    monthly. Rate shown is the rate in effect on March 31, 2006.
(g) The security is credit guaranteed, enhanced or has credit risk by a foreign
    entity. No concentration of any single foreign country was greater than 5%.
(h) Synthetic municipal instruments; involves the deposit into a trust of one or
    more long-term tax-exempt bonds or notes ("Underlying Bonds."), a sale of
    certificates evidencing interests in the trust to investors such as the
    Fund. The trustee receives the long-term fixed interest payments on the
    Underlying Bonds, and pays certificate holders variable rate interest
    payments based upon a short-term reset periodically.
(i) Security not registered under the Securities Act of 1933, as amended (e.g.,
    the security was purchased in a Rule 144A transaction or a Regulation D
    transaction). The security may be resold only pursuant to an exemption from
    registration under the 1933 Act, typically to qualified institutional
    buyers. The Fund has no rights to demand registration of these securities.
    The aggregate value of these securities at March 31, 2006 was $901,459,500,
    which represented 28.29% of the Fund's Net Assets. Unless otherwise
    indicated, these securities are not considered to be illiquid.

TAX-FREE INVESTMENTS TRUST

NOTES TO FINANCIAL STATEMENTS

March 31, 2006

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

Tax-Free Investments Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Trust is organized as a Delaware statutory
trust consisting of one portfolio, the Tax-Free Cash Reserve Portfolio (the
"Fund"). The Fund currently offers multiple classes of shares. Matters affecting
each class are voted on exclusively by the shareholders of each class.

    The Fund's investment objective is to provide as high a level of tax-exempt
income as is consistent with the preservation of capital and maintenance of
liquidity.

    Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. The risk of material loss as a result of such indemnification claims
is considered remote.

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including estimates
and assumptions related to taxation. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.   SECURITY VALUATIONS -- The Fund's securities are recorded on the basis of
     amortized cost which approximates value as permitted by Rule 2a-7 under the
     1940 Act. This method values a security at its cost on the date of purchase
     and, thereafter, assumes a constant amortization to maturity of any
     premiums or accretion of any discounts.

B.   SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions
     are accounted for on a trade date basis. Realized gains or losses on sales
     are computed on the basis of specific identification of the securities
     sold. Interest income, adjusted for amortization of premiums and accretion
     of discounts on investments, is recorded on the accrual basis from
     settlement date.

       Brokerage commissions and mark ups are considered transaction costs and
     are recorded as an increase to the cost basis of securities purchased
     and/or a reduction of proceeds on a sale of securities. Such transaction
     costs are included in the determination of realized gain (loss) from
     investment securities reported in the Statement of Operations and the
     Statement of Changes in Net Assets and the realized net gains (losses) on
     securities per share in the Financial Highlights. Transaction costs are
     included in the calculation of the Fund's net asset value and, accordingly,
     they reduce the Fund's total returns. These transaction costs are not
     considered operating expenses and are not reflected in net investment
     income reported in the Statement of Operations and Statement of Changes in
     Net Assets, or the net investment income per share and ratios of expenses
     and net investment income reported in the Financial Highlights, nor are
     they limited by any expense limitation arrangements between the Fund and
     the advisor.

       The Fund allocates realized capital gains and losses to a class based on
     the relative net assets of each class. The Fund allocates income to a class
     based on the relative value of the settled shares of each class.

C.   COUNTRY DETERMINATION -- For the purposes of making investment selection
     decisions and presentation in the Schedule of Investments, AIM may
     determine the country in which an issuer is located and/or credit risk
     exposure based on various factors. These factors include the laws of the
     country under which the issuer is organized, where the issuer maintains a
     principal office, the country in which the issuer derives 50% or more of
     its total revenues and the country that has the primary market for the
     issuer's securities, as well as other criteria. Among the other criteria
     that may be evaluated for making this determination are the country in
     which the issuer maintains 50% or more of its assets, the type of security,
     financial guarantees and enhancements, the nature of the collateral and the
     sponsor organization. Country of issuer and/or credit risk exposure has
     been determined to be United States of America unless otherwise noted.

D.   DISTRIBUTIONS -- Distributions from income are declared daily and paid
     monthly. Distributions from net realized capital gain, if any, are
     generally paid annually and recorded on ex-dividend date. The Fund may
     elect to use a portion of the proceeds from redemptions as distributions
     for federal income tax purposes.

E.   FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
     Subchapter M 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
     gain) which is distributed to shareholders. Therefore, no provision for
     federal income taxes is recorded in the financial statements.

       In addition, the Fund intends to invest in such municipal securities to
     allow it to qualify to pay shareholders "exempt-interest dividends", as
     defined in the Internal Revenue Code.

F.   EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
     class of the Fund and which are directly attributable to that class are
     charged to the operations of such class. All other expenses are allocated
     among the classes based on relative net assets.

TAX-FREE INVESTMENTS TRUST

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the 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 contractually agreed
to waive advisory fees and/or reimburse expenses to the extent necessary to
limit total annual fund operating expenses (excluding certain items discussed
below) to 0.22% of the Fund's average daily net assets through March 31, 2007.
In determining the advisor's obligation to waive advisory fees and/or reimburse
expenses, the following expenses are not taken into account, and could cause the
net annual fund operating expenses to exceed the numbers reflected above: (i)
Rule 12b-1 plan fees, if any; (ii) trustees' fees; (iii) federal registration
fees; (iv) interest: (v) taxes; (vi) extraordinary items; (vii) expenses related
to a merger or reorganization, as approved by the Fund's Board of Trustees; and
(viii) expenses that the Fund has incurred but did not actually pay because of
an expense offset arrangement. Currently, in addition to the expense
reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully
below, the expense offset arrangements from which the Fund may benefit are in
the form of credits that the Fund receives from banks where the Fund or its
transfer agent has deposits accounts in which it holds uninvested cash. Those
credits are used to pay certain expenses incurred by the Fund.

    For the year ended March 31, 2006, AIM waived fees of $1,762,263.

    At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting, communications
and trustee expenses. These expenses along with the related expense
reimbursement are included in the Statement of Operations. For the year ended
March 31, 2006, AMVESCAP reimbursed expenses of the Fund in the amount of $307.

    The Trust, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. Pursuant to such agreement, for the year ended
March 31, 2006, AIM was paid $605,661.

    The Trust, pursuant to a transfer agency and service agreement, has agreed
to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer
agency and shareholder services to the Fund. During the year ended March 31,
2006, AISI retained $527,776.

    Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Trust, FMC acts as the exclusive distributor of the
Fund's shares. The Trust has adopted a master distribution plan pursuant to Rule
12b-1 under the 1940 Act with respect to the Fund's Private Investment Class,
Personal Investment Class, Cash Management Class, Reserve Class, Resource Class
and Corporate Class (the "Plan"). The Plan provides that the Private Investment
Class, the Personal Investment Class, the Cash Management Class, the Reserve
Class, the Resource Class and the Corporate Class pay up to the maximum annual
rate of 0.50%, 0.75%, 0.10%, 1.00%, 0.20% and 0.03%, respectively, of the
average daily net assets attributable to such class. Of the Rule 12b-1 payment,
up to 0.25% of the average daily net assets of each class may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under such Plan
would constitute an asset-based sales charge. National Association of Securities
Dealers ("NASD") Rules impose a cap on the total amount of sales charges,
including asset-based sales charges, that may be paid by any class of shares of
the Fund. Currently, FMC has contractually agreed to waive a portion of its
compensation payable by the Fund such that compensation paid pursuant to the
Plan with respect to the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class and the Resource Class
equals the maximum annual rate of 0.25%, 0.55%, 0.08%, 0.87% and 0.16%,
respectively, of the average daily net assets attributable to such class through
March 31, 2007. Further, FMC voluntarily waived additional Rule 12b-1 plan fees
for the Reserve Class during the year in order to increase the yield. Waivers
may be modified or discontinued at any time. Pursuant to the Plan, for the year
ended March 31, 2006, the Private Investment Class, the Personal Investment
Class, the Cash Management Class, the Reserve Class, the Resource Class and the
Corporate Class paid $570,165, $112,400, $496,246, $144,953, $570,898 and
$3,442, respectively, after FMC waived Plan fees of $570,165, $40,873, $124,062,
$21,659, $142,724 and $0, respectively.

    Certain officers and trustees of the Trust are officers and directors of
AIM, AISI and/or FMC.

NOTE 3--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the Board
of Trustees of the Trust. The procedures have been designed to ensure that any
purchase or sale of securities by the Fund from or to another fund or portfolio
that is or could be considered an affiliate by virtue of having a common
investment advisor (or affiliated investment advisors), common Trustees and/or
common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined
under the procedures, each transaction is effected at the current market price.
Pursuant to these procedures, for the year ended March 31, 2006, the Fund
engaged in securities sales of $194,014,926, which resulted in net realized
gains (losses) of $0 and securities purchases of $14,773,207.

NOTE 4--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees who
also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include

                                       F-34


TAX-FREE INVESTMENTS TRUST

amounts accrued by the Fund to fund such retirement benefits. Obligations under
the deferred compensation and retirement plans represent unsecured claims
against the general assets of the Fund.

    During the year ended March 31, 2006, the Fund paid legal fees of $16,649
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 5--BORROWINGS

Pursuant to an exemptive order from the Securities and Exchange Commission
("SEC"), the Fund may participate in an interfund lending facility that AIM has
established for temporary borrowings by the AIM Funds. An interfund loan will be
made under this facility only if the loan rate (an average of the rate available
on bank loans and the rate available on investments in overnight repurchase
agreements) is favorable to both the lending fund and the borrowing fund. A loan
will be secured by collateral if the Fund's aggregate borrowings from all
sources exceeds 10% of the Fund's total assets. To the extent that the loan is
required to be secured by collateral, the collateral is marked to market daily
to ensure that the market value is at least 102% of the outstanding principal
value of the loan. The Fund did not borrow or lend under the facility during the
year ended March 31, 2006.

    Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with The Bank of New York, the custodian bank.
To compensate the custodian bank for such overdrafts, the overdrawn Fund may
either (i) leave funds as a compensating balance in the account so the custodian
can be compensated by earning the additional interest; or (ii) compensate by
paying the custodian bank at a rate agreed upon by the custodian bank and AIM,
not to exceed the rate contractually agreed upon.

retirement plan expenses.

    Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the amount
of capital loss carryforward actually available for the Fund to utilize. The
ability to utilize capital loss carryforward in the future may be limited under
the Internal Revenue Code and related regulations based on the results of future
transactions.

NOTE 9--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.


SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Additionally, AIM and ADI
created a $50 million fair fund ($30 million of which is civil penalties) to
compensate shareholders harmed by market timing and related activity in funds
advised by AIM, which was done pursuant to the terms of the settlement. These
two fair funds may increase as a result of contributions from third parties who
reach final settlements with the SEC or other regulators to resolve allegations
of market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a methodology
to be determined by AIM's independent distribution consultant, in consultation
with AIM and the independent trustees of the AIM Funds and acceptable to the
staff of the SEC. As the methodology is unknown at the present time, management
of AIM and the Fund are unable to estimate the impact, if any, that the
distribution of these two fair funds may have on the Fund or whether such
distribution will have an impact on the Fund's financial statements in the
future.

    At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.


PENDING LITIGATION AND REGULATORY INQUIRIES

  On August 30, 2005, the West Virginia Office of the State Auditor-Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI (Order No. 05-1318). The WVASC makes findings of
fact that AIM and ADI entered into certain arrangements permitting market timing
of the AIM Funds, including those formerly advised by IFG, and failed to
disclose these arrangements in the prospectuses for such Funds, and conclusions
of law to the effect that AIM and ADI violated the West Virginia securities
laws. The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions, including restitution to affected investors,
disgorgement of fees, reimbursement of investigatory, administrative and legal
costs and an "administrative assessment," to be determined by the Commissioner.
Initial research indicates that these damages could be limited or capped by
statute.

    Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:

    - that the defendants permitted improper market timing and related activity
      in the AIM Funds;

    - that certain AIM Funds inadequately employed fair value pricing;

    - that the defendants charged excessive advisory and/or distribution fees
      and failed to pass on to shareholders the perceived savings generated by
      economies of scale and that the defendants adopted unlawful distribution
      plans; and

    - that the defendants improperly used the assets of the AIM Funds to pay
      brokers to aggressively promote the sale of the AIM Funds over other
      mutual funds and that the defendants concealed such payments from
      investors by disguising them as brokerage commissions.

    These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.

    All lawsuits based on allegations of market timing, late trading and related
issues have been transferred or conditionally transferred to the United States
District Court for the District of Maryland (the "MDL Court"). Pursuant to an
Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims
for pre-trial purposes into three amended complaints against various AIM- and
IFG-related parties: (i) a Consolidated Amended Class Action Complaint
purportedly brought on behalf of shareholders of the AIM Funds; (ii) a
Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of
the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint
for Violations of the Employee Retirement Income Securities Act ("ERISA")
purportedly brought on behalf of participants in AMVESCAP's 401(k) plan.

    On March 1, 2006, the MDL Court entered orders on Defendants' Motions to
dismiss in the derivative and class action lawsuits. The MDL Court dismissed all
derivative causes of action in the derivative lawsuit but two: (i) the excessive
fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940
Act"); and (ii) the "control person liability" claim under Section 48 of the
1940 Act. The MDL Court dismissed all claims asserted in the class action
lawsuit but three: (i) the securities fraud claims under Section 10(b) of the
Securities Exchange Act of 1934; (ii) the excessive fee claim under Section
36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery
of fees associated with the assets involved in market timing); and (iii) the
"control person liability" claim under Section 48 of the 1940 Act. Based on the
MDL Court's March 1, 2006 orders, all claims asserted against the Funds that
have been transferred to the MDL Court have been dismissed, although certain
Funds remain nominal defendants in the derivative lawsuit. Defendants filed
their Original Answer in the class action lawsuit on March 31, 2006. The MDL
Court has indefinitely deferred Defendants' obligation to answer the derivative
lawsuit.

    On February 27, 2006, Judge Motz for the MDL Court issued a memorandum
opinion on the AMVESCAP defendants' motion to dismiss the ERISA lawsuit. Judge
Motz granted the motion in part and denied the motion in part, holding that: (i)
plaintiff has both constitutional and statutory standing to

                                       F-38


TAX-FREE INVESTMENTS TRUST

NOTE 9--LEGAL PROCEEDINGS--(CONTINUED)

pursue her claims under ERISA sec. 502(a)(2); (ii) plaintiff lacks standing
under ERISA sec. 502(a)(3) to obtain equitable relief; (iii) the motion is
granted as to the claims alleged under ERISA sec. 404 for failure to prudently
and loyally manage plan assets against certain AMVESCAP defendants; (iv) the
motion is denied as to the claims alleged under ERISA sec. 404 for failure to
prudently and loyally manage plan assets against AMVESCAP and certain other
AMVESCAP defendants. The opinion also: (i) confirmed plaintiff's abandonment of
her claims that defendants engaged in prohibited transactions and/or
misrepresentation; (ii) postponed consideration of the duty to monitor and
co-fiduciary duty claims until after any possible amendments to the complaints;
(iii) stated that plaintiff may seek leave to amend her complaint within 40 days
of the date of filing of the memorandum opinion. On April 4, 2006, Judge Motz
entered an order implementing these rulings in the ERISA (Calderon) lawsuit
against the AMVESCAP defendants. Plaintiffs indicated that they intend to amend
their complaint in light of this order. Defendants will have 30 days after such
amendment to answer or otherwise respond.

    IFG, AIM, ADI and/or related entities and individuals have received
inquiries from numerous regulators in the form of subpoenas or other oral or
written requests for information and/or documents related to one or more of the
following issues, among others, some of which concern one or more AIM Funds:
market timing activity, late trading, fair value pricing, excessive or improper
advisory and/or distribution fees, mutual fund sales practices, including
revenue sharing and directed-brokerage arrangements, investments in securities
of other registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost security
holders. IFG, AIM and ADI have advised the Fund that they are providing full
cooperation with respect to these inquiries. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.

    At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Pending Litigation and Regulatory
Inquiries described above may have on AIM, ADI or the Fund.

    As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

TAX-FREE INVESTMENTS TRUST

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Tax-Free Investments Trust
and Resource Class Shareholders of Tax-Free Cash Reserve Portfolio:



In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Tax-Free Cash Reserve Portfolio
(the "Fund") at March 31, 2006, the results of its operations, the changes in
its net assets and the Resource Class financial highlights for the year then
ended, in conformity with accounting principles generally accepted in the United
States of America. These financial statements and Resource Class financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at March 31, 2006 by correspondence with the custodian and
brokers, provides a reasonable basis for our opinion. The statement of changes
in net assets of the Fund for the year ended March 31, 2005 and the Resource
Class financial highlights for each of the periods ended on or before March 31,
2005 were audited by another independent registered public accounting firm whose
report dated May 18, 2005 expressed an unqualified opinion on those statements.

(1)      With respect to the provision of non-audit services, the pre-approval
         requirement is waived pursuant to a de minimis exception if (i) such
         services were not recognized as non-audit services by the Registrant at
         the time of engagement, (ii) the aggregate amount of all such services
         provided is no more than 5% of the aggregate audit and non-audit fees
         paid by the Registrant, AIM and AIM Affiliates during a fiscal year;
         and (iii) such services are promptly approved by the Registrant's Audit
         Committee prior to the completion of the audit by the Audit Committee.

(2)      Audit-Related fees for the fiscal year ended March 31, 2005 includes
         fees billed for services to test and report on the controls and
         operations of an affiliated transfer agent.

(3)      Including the fees for services not required to be pre-approved by the
         registrant's audit committee, PWC billed AIM and AIM Affiliates
         aggregate non-audit fees of $0 for the fiscal year ended 2006, and E&Y
         billed AIM and AIM Affiliates aggregate non-audit fees of $302,621 for
         the fiscal year ended 2005, for non-audit services rendered to AIM and
         AIM Affiliates.

         The Audit Committee also has considered whether the provision of
         non-audit services that were rendered to AIM and AIM Affiliates that
         were not required to be pre-approved pursuant to SEC regulations, if
         any, is compatible with maintaining the principal accountant's
         independence.


                  PRE-APPROVAL OF AUDIT AND NON-AUDIT SERVICES
                             POLICIES AND PROCEDURES
                      As adopted by the Audit Committees of
                           the AIM Funds (the "Funds")
                         Last Amended September 13, 2005


I.       STATEMENT OF PRINCIPLES

Under the Sarbanes-Oxley Act of 2002 and rules adopted by the Securities and
Exchange Commission ("SEC") ("Rules"), the Audit Committees of the Funds' (the
"Audit Committee") Board of Directors/Trustees (the "Board") are responsible for
the appointment, compensation and oversight of the work of independent
accountants (an "Auditor"). As part of this responsibility and to assure that
the Auditor's independence is not impaired, the Audit Committees pre-approve the
audit and non-audit services provided to the Funds by each Auditor, as well as
all non-audit services provided by the Auditor to the Funds' investment adviser
and to affiliates of the adviser that provide ongoing services to the Funds
("Service Affiliates") if the services directly impact the Funds' operations or
financial reporting. The SEC Rules also specify the types of services that an
Auditor may not provide to its audit client. The following policies and
procedures comply with the requirements for pre-approval and provide a mechanism
by which management of the Funds may request and secure pre-approval of audit
and non-audit services in an orderly manner with minimal disruption to normal
business operations.

Proposed services either may be pre-approved without consideration of specific
case-by-case services by the Audit Committees ("general pre-approval") or
require the specific pre-approval of the Audit Committees ("specific
pre-approval"). As set forth in these policies and procedures, unless a type of
service has received general pre-approval, it will require specific pre-approval
by the Audit Committees. Additionally, any fees exceeding 110% of estimated
pre-approved fee levels provided at the time the service was pre-approved will
also require specific approval by the Audit Committees before payment is made.
The Audit Committees will also consider the impact of additional fees on the
Auditor's independence when determining whether to approve any additional fees
for previously pre-approved services.

The Audit Committees will annually review and generally pre-approve the services
that may be provided by each Auditor without obtaining specific pre-approval
from the Audit Committee. The term of any general pre-approval runs from the
date of such pre-approval through September 30th of the following year, unless
the Audit Committees consider a different period and state otherwise. The Audit
Committees will add to or subtract from the list of general pre-approved
services from time to time, based on subsequent determinations.

The purpose of these policies and procedures is to set forth the guidelines to
assist the Audit Committees in fulfilling their responsibilities.

II.      DELEGATION

The Audit Committees may from time to time delegate pre-approval authority to
one or more of its members who are Independent Directors. All decisions to
pre-approve a service by a delegated member shall be reported to the Audit
Committee at its next quarterly meeting.

III.     AUDIT SERVICES

The annual audit services engagement terms will be subject to specific
pre-approval of the Audit Committees. Audit services include the annual
financial statement audit and other procedures such as tax provision work that
is required to be performed by the independent auditor to be able to form an
opinion on the Funds' financial statements. The Audit Committee will obtain,
review and consider sufficient information concerning the proposed Auditor to
make a reasonable evaluation of the Auditor's qualifications and independence.



In addition to the annual Audit services engagement, the Audit Committees may
grant general pre-approval for other audit services, which are those services
that only the independent auditor reasonably can provide. Other Audit services
may include services such as issuing consents for the inclusion of audited
financial statements with SEC registration statements, periodic reports and
other documents filed with the SEC or other documents issued in connection with
securities offerings.

IV.      NON-AUDIT SERVICES

The Audit Committees may provide general pre-approval of types of non-audit
services described in this Section IV to the Funds and its Service Affiliates if
the Audit Committees believe that the provision of the service will not impair
the independence of the Auditor, is consistent with the SEC's Rules on auditor
independence, and otherwise conforms to the Audit Committee's general principles
and policies as set forth herein.

The Audit Committees may provide specific pre-approval of any non-audit services
to the Funds and its Service Affiliates if the Audit Committees believe that the
provision of the service will not impair the independence of the auditor, is
consistent with the SEC Rules on auditor independence, and otherwise conforms to
the Audit Committees' general principles and policies as set forth herein.

AUDIT-RELATED SERVICES

"Audit-related services" are assurance and related services that are reasonably
related to the performance of the audit or review of the Fund's financial
statements or that are traditionally performed by the independent auditor.
Audit-related services include, among others, accounting consultations related
to accounting, financial reporting or disclosure matters not classified as
"Audit services"; assistance with understanding and implementing new accounting
and financial reporting guidance from rulemaking authorities; and agreed-upon
procedures related to mergers, compliance with ratings agency requirements and
interfund lending activities.

TAX SERVICES

"Tax services" include, but are not limited to, the review and signing of the
Funds' federal tax returns, the review of required distributions by the Funds
and consultations regarding tax matters such as the tax treatment of new
investments or the impact of new regulations. The Audit Committee will
scrutinize carefully the retention of the Auditor in connection with a
transaction initially recommended by the Auditor, the major business purpose of
which may be tax avoidance or the tax treatment of which may not be supported in
the Internal Revenue Code and related regulations. The Audit Committee will
consult with the Funds' Treasurer (or his or her designee) and may consult with
outside counsel or advisors as necessary to ensure the consistency of Tax
services rendered by the Auditor with the foregoing policy.

No Auditor shall represent any Fund or any Service Provider before a tax court,
district court or federal court of claims.

ALL OTHER AUDITOR SERVICES

The Audit Committees may pre-approve non-audit services classified as "All other
services" that are not categorically prohibited by the SEC, as listed in Exhibit
1 to this policy.

V.       PRE-APPROVAL FEE LEVELS OR ESTABLISHED AMOUNTS

Pre-approval of estimated fees or established amounts for services to be
provided by the Auditor under general or specific pre-approval policies will be
set periodically by the Audit Committees. Any proposed fees exceeding 110% of
the maximum estimated pre-approved fees or established amounts for pre-approved
audit and non-audit services will be reported to the Audit Committees at the
quarterly Audit Committees meeting and will require specific approval by the
Audit Committees before payment is made. The Audit Committee will always factor
in the overall relationship of fees for audit and non-audit services in
determining whether to pre-approve any such services and in determining whether
to approve any additional fees exceeding 110% of the maximum pre-approved fees
or established amounts for previously pre-approved services.



VI.      PROCEDURES

On an annual basis, A I M Advisors, Inc. ("AIM") will submit to the Audit
Committees for general pre-approval, a list of non-audit services that the Funds
or Service Affiliates of the Funds may request from the Auditor. The list will
describe the non-audit services in reasonable detail and will include an
estimated range of fees and such other information as the Audit Committee may
request.

Each request for services to be provided by the Auditor under the general
pre-approval of the Audit Committees will be submitted to the Funds' Treasurer
(or his or her designee) and must include a detailed description of the services
to be rendered. The Treasurer or his or her designee will ensure that such
services are included within the list of services that have received the general
pre-approval of the Audit Committees. The Audit Committees will be informed at
the next quarterly scheduled Audit Committees meeting of any such services for
which the Auditor rendered an invoice and whether such services and fees had
been pre-approved and if so, by what means.

Each request to provide services that require specific approval by the Audit
Committees shall be submitted to the Audit Committees jointly by the Fund's
Treasurer or his or her designee and the Auditor, and must include a joint
statement that, in their view, such request is consistent with the policies and
procedures and the SEC Rules.

Non-audit services pursuant to the de minimis exception provided by the SEC
Rules will be promptly brought to the attention of the Audit Committees for
approval, including documentation that each of the conditions for this
exception, as set forth in the SEC Rules, has been satisfied.

On at least an annual basis, the Auditor will prepare a summary of all the
services provided to any entity in the investment company complex as defined in
section 2-01(f)(14) of Regulation S-X in sufficient detail as to the nature of
the engagement and the fees associated with those services.

The Audit Committees have designated the Funds' Treasurer to monitor the
performance of all services provided by the Auditor and to ensure such services
are in compliance with these policies and procedures. The Funds' Treasurer will
report to the Audit Committee on a periodic basis as to the results of such
monitoring. Both the Funds' Treasurer and management of AIM will immediately
report to the chairman of the Audit Committee any breach of these policies and
procedures that comes to the attention of the Funds' Treasurer or senior
management of AIM.

ITEM 11.     CONTROLS AND PROCEDURES.

(a)               As of March 21, 2006, an evaluation was performed under the
                  supervision and with the participation of the officers of the
                  Registrant, including the PEO and PFO, to assess the
                  effectiveness of the Registrant's disclosure controls and
                  procedures, as that term is defined in Rule 30a-3(c) under the
                  Investment Company Act of 1940 (the "Act"), as amended. Based
                  on that evaluation, the Registrant's officers, including the
                  PEO and PFO, concluded that, as of March 21, 2006, the
                  Registrant's disclosure controls and procedures were
                  reasonably designed to ensure: (1) that information required
                  to be disclosed by the Registrant on Form N-CSR is recorded,
                  processed, summarized and reported within the time periods
                  specified by the rules and forms of the Securities and
                  Exchange Commission; and (2) that material information
                  relating to the Registrant is made known to the PEO and PFO as
                  appropriate to allow timely decisions regarding required
                  disclosure.

 (b)              There have been no changes in the Registrant's internal
                  control over financial reporting (as defined in Rule 30a-3(d)
                  under the Act) that occurred during the second fiscal quarter
                  of the period covered by the report that have materially
                  affected, or are reasonably likely to materially affect, the
                  Registrant's internal control over financial reporting.
