ITEM 1.  REPORTS TO STOCKHOLDERS.


FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Trust, you incur ongoing costs, including
management fees; service fees and other Trust expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Trust and to compare these costs with the ongoing costs of investing in
other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended June 30, 2007.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line, together with the amount you invested, to estimate the expense that you
paid over the period. Simply divide your account value by $1,000.00 (for
example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply
the result by the number in the "actual" line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Trust's actual expense ratio, and an assumed rate of
return of 5% per year before expenses, which is not the Trust's actual return.
The hypothetical account values and expenses may not be used to estimate the
actual ending account balance or expenses you paid for the period. You may use
this information to compare the ongoing costs of investing in the Trust and
other funds. To do so, compare this 5% hypothetical example for the class of
shares you hold with the 5% hypothetical examples that appear in the shareholder
reports of the other funds.

Hypothetical                       1,000.00      1,021.47      3.36

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 181/365 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended June 30, 2007 is as follows:

EXPENSE RATIO
- -------------
   0.67%

The expense ratio reflects reduction to custodian fees. The "Financial
Highlights" tables in the Trust's financial statements, included in this report,
also show the gross expense ratio, without such waivers or reimbursements.

1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Tax Exempt Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek the maximum short-term interest
income exempt from federal income taxes that is consistent with low capital risk
and the maintenance of liquidity. The Trust's investment advisor is Centennial
Asset Management Corporation (the Manager), a wholly owned subsidiary of
OppenheimerFunds, Inc. (OFI).

      The following is a summary of significant accounting policies consistently
followed by the Trust.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern
time on each day the New York Stock Exchange (the "Exchange") is open for
trading. As permitted under Rule 2a-7 of the Investment Company Act of 1940,
portfolio securities are valued on the basis of amortized cost, which
approximates market value. If amortized cost is determined not to approximate
market value, the fair value of the portfolio securities will be determined
under procedures approved by the Trust's Board of Trustees.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Trust intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income to shareholders,
therefore, no federal income or excise tax provision is required.

The tax  components of capital shown in the table below  represent  distribution
requirements the Trust must satisfy under the income tax regulations, losses the
Trust may be able to offset  against  income and gains  realized in future years
for federal income tax purposes.

           UNDISTRIBUTED NET       UNDISTRIBUTED     ACCUMULATED LOSS

           $1,987,856                   $293,085                  $--

1. During the fiscal year ended June 30, 2007, the Trust did not utilize any
capital loss carryforward.

2. During the fiscal year ended June 30, 2006, the Trust utilized $5,544 of
capital loss carryforward to offset capital gains realized in that fiscal year.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Trust.


                        26 | CENTENNIAL TAX EXEMPT TRUST



The tax character of distributions paid during the years ended June 30, 2007 and
June 30, 2006 was as follows:

        --------------------------------------------------------------
        Distributions paid from:
        Exempt-interest dividends         $53,632,623      $40,741,047
        Long-term capital gain                281,265               --
                                          ----------------------------
        Total                             $53,913,888      $40,741,047
                                          ============================

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral plan for independent trustees that enables trustees to elect to defer
receipt of all or a portion of the annual compensation they are entitled to
receive from the Trust. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Trust or in other Oppenheimer funds
selected by the Trustee. The Trust purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Trust asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Trust, and will not materially affect the
Trust's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the compensation deferral plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Trust on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Trust pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Trust, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Trust
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

INDEMNIFICATIONS. The Trust's organizational documents provide current and
former trustees and officers with a limited indemnification against liabilities
arising in connection with the performance of their duties to the Trust. In the
normal course of business, the Trust may also enter into contracts that provide
general indemnifications. The Trust's maximum exposure under these arrangements
is unknown as this would be dependent on future claims that may be made against
the Trust. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

The Trust has authorized an unlimited number of no par value shares of
beneficial interest. Transactions in shares of beneficial interest were as
follows:

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Trust which provides for a fee at an
annual rate of average net assets as shown in the following table:

                    FEE SCHEDULE
                    ---------------------------------------
                    Up to $250 million               0.500%
                    Next $250 million                0.475
                    Next $250 million                0.450
                    Next $250 million                0.425
                    Next $250 million                0.400
                    Next $250 million                0.375
                    Next $500 million                0.350
                    Over $2 billion                  0.325

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. The Trust pays the Manager a fee of $1,500 per year
for preparing and filing the Trust's tax returns.


                        28 | CENTENNIAL TAX EXEMPT TRUST



- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. Shareholder Services, Inc. (SSI) acts as the transfer and
shareholder servicing agent for the Trust and for other registered investment
companies. The Trust pays SSI a per account fee. For the year ended June 30,
2007, the Trust paid $497,052 to SSI for services to the Trust.

- --------------------------------------------------------------------------------
SERVICE PLAN (12b-1) FEES. The Trust has adopted a Service Plan (the "Plan"). It
reimburses Centennial Asset Management Corporation (the "Distributor"), for a
portion of its costs incurred for services provided to accounts that hold shares
of the Trust. Reimbursement is made periodically depending on asset size, at an
annual rate of up to 0.20% of the average annual net assets of the Trust. The
Distributor currently uses all of those fees to pay dealers, brokers, banks and
other financial institutions periodically for providing personal services and
maintenance of accounts of their customers that hold shares of the Trust. Fees
incurred by the Trust under the Plan are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. Under the investment advisory agreement,
when the value of the Trust's net assets is less than $1.5 billion, the annual
fee payable to the Manager shall be reduced by $100,000 based on average net
assets computed daily and paid monthly at the annual rates. However, the annual
fee cannot be less than $0.

      SSI has voluntarily agreed to limit transfer and shareholder servicing
agent fees to 0.35% of average annual net assets of the Trust. This undertaking
may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
4. ILLIQUID SECURITIES

As of June 30, 2007, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Trust will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Trust's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Trust's tax return
will be ultimately sustained. A tax liability and expense must be recorded in
respect of any tax position that, in Management's judgment, will not be fully
realized. FIN 48 is effective

5. RECENT ACCOUNTING PRONOUNCEMENTS Continued

for fiscal years beginning after December 15, 2006. As of June 30, 2007, the
Manager has evaluated the implications of FIN 48 and does not currently
anticipate a material impact to the Trust's financial statements. The Manager
will continue to monitor the Trust's tax positions prospectively for potential
future impacts.

      In September 2006, ("FASB") issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of June 30, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF CENTENNIAL TAX EXEMPT TRUST: We
have audited the accompanying statement of assets and liabilities of Centennial
Tax Exempt Trust (the "Trust"), including the statement of investments, as of
June 30, 2007, and the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the five years in the
period then ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of June 30, 2007, by correspondence with the custodian
and brokers. We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Trust as of June 30, 2007, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2008, if applicable, shareholders of record will receive information
regarding all taxable dividends and distributions paid to them by the Trust
during calendar year 2007. Regulations of the U.S. Treasury Department require
the Trust to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.0002 per share were paid to shareholders
on December 15, 2006. Whether received in stock or in cash, the capital gain
distribution should be treated by shareholders as a gain from the sale of the
capital assets held for more than one year (long-term capital gains).

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Trust to the Internal Revenue Service. Because
of the complexity of the federal regulations which may affect your individual
tax return and the many variations in state and local tax regulations, we
recommend that you consult your tax advisor for specific guidance.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.   The Fund's Governance Committee (the "Committee") will evaluate potential
     Board candidates to assess their qualifications. The Committee shall have
     the authority, upon approval of the Board, to retain an executive search
     firm to assist in this effort. The Committee may consider recommendations
     by business and personal contacts of current Board members and by executive
     search firms which the Committee may engage from time to time and may also
     consider shareholder recommendations. The Committee may consider the advice
     and recommendation of the Funds' investment manager and its affiliates in
     making the selection.

2.   The Committee shall screen candidates for Board membership. The Committee
     has not established specific qualifications that it believes must be met by
     a trustee nominee. In evaluating trustee nominees, the Committee considers,
     among other things, an individual's background, skills, and experience;
     whether the individual is an "interested person" as defined in the
     Investment Company Act of 1940; and whether the individual would be deemed
     an "audit committee financial expert" within the meaning of applicable SEC
     rules. The Committee also considers whether the individual's background,
     skills, and experience will complement the background, skills, and
     experience of other nominees and will contribute to the Board. There are no
     differences in the manner in which the Committee evaluates nominees for
     trustees based on whether the nominee is recommended by a shareholder.

3.   The Committee may consider nominations from shareholders for the Board at
     such times as the Committee meets to consider new nominees for the Board.
     The Committee shall have the sole discretion to determine the candidates to
     present to the Board and, in such cases where required, to shareholders.
     Recommendations for trustee nominees should, at a minimum, be accompanied
     by the following:

     o    the name, address, and business, educational, and/or other pertinent
          background of the person being recommended;



     o    a statement concerning whether the person is an "interested person" as
          defined in the Investment Company Act of 1940;

     o    any other information that the Funds would be required to include in a
          proxy statement concerning the person if he or she was nominated; and

     o    the name and address of the person submitting the recommendation and,
          if that person is a shareholder, the period for which that person held
          Fund shares.

     The recommendation also can include any additional information which the
     person submitting it believes would assist the Committee in evaluating the
     recommendation.

4.   Shareholders should note that a person who owns securities issued by
     Massachusetts Mutual Life Insurance Company (the parent company of the
     Funds' investment adviser) would be deemed an "interested person" under the
     Investment Company Act of 1940. In addition, certain other relationships
     with Massachusetts Mutual Life Insurance Company or its subsidiaries, with
     registered broker-dealers, or with the Funds' outside legal counsel may
     cause a person to be deemed an "interested person."

5.   Before the Committee decides to nominate an individual as a trustee,
     Committee members and other directors customarily interview the individual
     in person. In addition, the individual customarily is asked to complete a
     detailed questionnaire which is designed to elicit information which must
     be disclosed under SEC and stock exchange rules and to determine whether
     the individual is subject to any statutory disqualification from serving as
     a trustee of a registered investment company.

ITEM 11.  CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 06/30/2007, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
