The Trust files its complete schedule of portfolio  holdings with the Securities
and Exchange  Commission for the first and third quarters of each fiscal year on
Form N-Q within  sixty days after the end of the period.  The Trust's  Forms N-Q
are available on the  Commission's  web site at  http://www.sec.gov,  and may be
reviewed and copied at the Commission's Public Reference Room in Washington, DC.
Information  on the  operation of the Public  Reference  Room may be obtained by
calling 1-800-SEC-0330.

Since the Funds in SEI Daily  Income  Trust  typically  hold only  fixed  income
securities,  they  generally are not expected to hold  securities for which they
may be required to vote proxies.  Regardless, in light of the possibility that a
Fund  could hold a security  for which a proxy is voted,  the Trust has  adopted
proxy voting  policies.  A description of the policies and  procedures  that the
Trust uses to determine how to vote proxies relating to portfolio securities, as
well as information  relating to how a Fund voted proxies  relating to portfolio
securities  during the most recent  12-month  period ended June 30, is available
without  charge (i) upon  request,  by calling  1-800-DIAL-SEI;  and (ii) on the
Commission's website at http://www.sec.gov.

================================================================================


NOTES TO FINANCIAL STATEMENTS


Notes to Financial Statements (Unaudited)


1. ORGANIZATION
SEI Daily Income Trust (the "Trust") was organized as a Massachusetts business
trust under a Declaration of Trust dated March 15, 1982.

The Trust is registered under the Investment Company Act of 1940, as amended, as
a diversified, open-end investment company with ten operational Funds: the Money
Market, Government, Government II, Prime Obligation, Treasury, Treasury II (each
a "Fund", collectively the "Money Market Funds"), the Short-Duration Government,
Intermediate-Duration Government, GNMA, and Ultra Short Bond, previously known
as Corporate Daily Income (each a "Fund", collectively the "Fixed Income
Funds"). The Funds' prospectuses provide a description of each Fund's investment
objectives, policies and strategies. The assets of each Fund are segregated, and
a shareholder's interest is limited to the Fund in which shares are held.

2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies followed by the
Funds.

USE OF ESTIMATES -- 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
amount of assets and liabilities and disclosure of contingent assets at the date
of the financial statements, and the reported results of operations during the
reporting period. Actual results could differ from those estimates.

SECURITY VALUATION -- Investment securities of the Money Market Funds are stated
at amortized cost which approximates market value. Under this valuation method,
purchase discounts and premiums are accreted and amortized ratably to maturity
and are included in interest income.

Investment securities of the Fixed Income Funds listed on a securities exchange,
market or automated quotation system for which quotations are readily available
are valued at the last quoted sale price on the primary exchange or market on
which they are traded, or, if there is no such reported sale, at the most recent
quoted bid price. If available, debt securities are priced based upon valuations
provided by independent, third-party pricing agents. Such values generally
reflect the last reported sales price if the security is actively traded. The
third-party pricing agents may also value debt securities at an evaluated bid
price by employing methodologies that utilize actual market transactions,
broker-supplied valuations, or other methodologies designed to identify the
market value for such securities. Debt obligations with remaining maturities of
sixty days or less may be valued at their amortized cost, which approximates
market value.

Prices for most securities held in the Funds are provided daily by recognized
independent pricing agents. If a security price cannot be obtained from an
independent, third-party pricing agent, the Funds seek to obtain a bid price
from at least one independent broker.

Securities for which market prices are not "readily available" are valued in
accordance with Fair Value Procedures established by the Funds' Board of
Trustees. The Funds' Fair Value Procedures are implemented through a Fair Value
Committee (the "Committee") designated by the Funds' Board of Trustees. Some of
the more common reasons that may necessitate that a security be valued using
Fair Value Procedures include: the security's trading has been halted or
suspended; the security has been de-listed from a national exchange; the
security's primary trading market is temporarily closed at a time when under
normal conditions it would be open; or the security's primary pricing source is
not able or willing to provide a price. When a security is valued in accordance
with the Fair Value Procedures, the Committee will determine the value after
taking into consideration relevant information reasonably available to the
Committee. As of July 31, 2005, there were no fair valued securities in the
Funds.

SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on the trade date of the security purchase or sale. Costs used in
determining net realized capital gains and losses on the sale of securities are
those of the specific securities sold, adjusted for the accretion and
amortization of purchase discounts and premiums during the respective holding
period. Interest income is recorded on the accrual basis. Purchase discounts and
premiums on securities held in the Fixed Income Funds are accreted and amortized
over the life of each security. Paydown gains and losses are classified as
interest income.

REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by each Fund's custodian bank until maturity of the
repurchase agreements. Provisions of the agreements and the Trust's policies
ensure that the market value of the collateral, including accrued interest
thereon, is sufficient in the event of default by the counterparty. The Funds
also invest in tri-party repurchase agreements. Securities held as collateral
for tri-party repurchase agreements are maintained by the broker's custodian
bank in a segregated account until maturity of the repurchase agreement.
Provisions of the agreements ensure that the market value of the collateral,
including accrued interest thereon, is sufficient in the event of default. If
the counterparty defaults and the value of the collateral declines, or if the
counterparty enters into an insolvency proceeding, realization of the collateral
by a Fund may be delayed or limited.

FUTURES CONTRACTS -- The Intermediate-Duration Government Fund and the GNMA Fund
utilized futures contracts during the six months

- --------------------------------------------------------------------------------
SEI Daily Income Trust / Semi-Annual Report / July 31, 2005                   39


================================================================================

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)



ended July 31, 2005. The Funds' investment in these futures contracts is
designed to enable the Funds to more closely approximate the performance of
their benchmark indices.

Initial margin deposits of cash or securities are made upon entering into
futures contracts. The contracts are "marked-to-market" daily and the resulting
changes in value are accounted for as unrealized gains and losses. Variation
margin payments are paid or received, depending upon whether unrealized losses
or gains are incurred. When the contract is closed, the Funds record a realized
gain or loss equal to the difference between the proceeds from (or cost of) the
closing transaction and the amount invested in the contract.

Risks related to futures contracts include the possibility that there may not be
a liquid market for the contracts, that the changes in the value of the contract
may not directly correlate with changes in the value of the underlying
securities, and that the counterparty to a contract may default on its
obligation to perform. The notional amount presented in the Statement of Net
Assets in the Intermediate-Duration Government Fund and the GNMA Fund represents
the Fund's total exposure in such contracts, whereas only the net unrealized
appreciation (depreciation) is reflected in the Fund's net assets.

TBA AND OTHER PURCHASE COMMITMENTS -- The Funds may engage in "to be announced"
("TBA") security transactions. Such transactions involve commitments to purchase
securities for a fixed price at a future date. Purchase commitments may be
considered securities and involve a risk of loss if the value of the security to
be purchased declines prior to settlement date, which risk is in addition to the
risk of decline in the value of a Fund's other assets. Unsettled purchase
commitments are valued at the current market value of the underlying securities,
according to the procedures described under "Security Valuation" above.

CLASSES -- Class-specific expenses are borne by that class of shares. Income,
realized and unrealized gains/losses and non-class-specific expenses are
allocated to the respective class on the basis of relative daily net assets.

EXPENSES -- Expenses that are directly related to one of the Funds are charged
directly to that Fund. Other operating expenses of the Trust, which are not
directly associated to a specific Fund, are prorated to the Funds on the basis
of relative net assets.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to
shareholders, which are determined in accordance with Federal tax regulations,
are recorded on the ex-dividend date. Dividends from net investment income are
declared on a daily basis and are payable on the first business day of the
following month. Any net realized capital gains on sales of securities for a
Fund are distributed to its shareholders at least annually.

3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES ADMINISTRATION AGREEMENT --
SEI Investments Fund Management (the "Administrator") provides administrative
services to the Funds for annual fees, based on the average daily net assets of
the respective funds, as presented below:

   Money Market Fund                                             .33%

   Treasury II Fund                                              .24%
   Short-Duration Government Fund                                .35%
   Intermediate-Duration Government Fund                         .35%
   GNMA Fund                                                     .32%
   Ultra Short Bond Fund                                         .35%

However, the Administrator has also voluntarily agreed to waive a portion or its
entire fee, for various classes of shares in various funds, to limit total
annual expenses to the following amounts (expressed as a percentage of the
Funds' daily net assets). The Administrator has the right, at its sole
discretion, to terminate these voluntary waivers at any time.

During the year expenses related to a proxy conducted by the Trust were charged
to the Funds above the cap.

During the six month period ended July 31, 2005, the Short-Duration Government
Fund and the Intermediate-Duration Government Fund were reimbursed by the
Administrator, deemed as a "Payment by Affiliate" on the Statements of
Operations, for losses incurred of $7,422 and $3,906, respectively, due to the
sale of shares in several option contracts that were inadvertently purchased.

DISTRIBUTION AGREEMENT -- SEI Investments Distribution Co. (the "Distributor"),

* These payments are characterized as "compensation" and are not directly
  tied to expenses incurred by the Distributor. The payments the Distributor
  receives during any year may therefore be higher or lower than its actual
  expenses. These payments may be used to compensate sweep class shareholders
  who provide distribution-related services to their customers.

The Distributor has voluntarily waived all or a portion of the shareholder
servicing fees for class A of each fund since inception of the plan. Such
waivers are voluntary and may be discontinued at any time.

Certain officers and Trustees of the Trust are also officers and/or Trustees of
the Administrator or the adviser. The Trust pays each unaffiliated Trustee an
annual fee for attendance at quarterly, interim, and committee meetings. The
Administrator or the adviser pays compensation of officers and affiliated
Trustees.

4. INVESTMENT ADVISORY AND CUSTODIAN AGREEMENTS

SEI Investments Management Corporation ("SIMC") serves as each Fund's investment
adviser and "manager of managers" under an investment advisory agreement
approved by the shareholders of each Fund. For its services, SIMC receives an
annual fee equal to .075% of the Trust's average daily net assets up to $500
million and .02% of such net assets in excess of $500 million.

Pursuant to the "manager of managers" structure, the Board of Trustees approved
Banc of America Capital Management, LLC ("BACAP") as each Money Market Fund's
investment sub-adviser under an investment sub-advisory agreement approved by
the shareholders of each Fund.

Wellington Management Company LLP, ("Wellington LLP") serves as Sub-Adviser to
the Short-Duration Government, Intermediate-Duration Government, GNMA and Ultra
Short Bond Funds.

Wachovia Bank, N.A. serves as the custodian of the Funds. The custodian plays no
role in determining the investment policies of the Funds or which securities are
to be purchased or sold in the Funds.


5. INVESTMENT TRANSACTIONS

6. FEDERAL TAX INFORMATION

It is each Fund's intention to continue to qualify as a regulated investment
company for Federal income tax purposes and distribute all of its taxable income
(including net capital gains). Accordingly, no provision for Federal income
taxes is required.

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)



Reclassification of components of net assets -- The timing and characterization
of certain income and capital gain distributions are determined annually in
accordance with Federal tax regulations which may differ from accounting
principles generally accepted in the United States. As a result, net investment
income (loss) and net realized gain (loss) on investment transactions for the
reporting period may differ from distributions during such period. These
book/tax differences may be temporary or permanent in nature. To the extent
these differences are permanent, they are charged or credited to paid-in
capital, undistributed net investment income or accumulated net realized gain,
as appropriate, in the periods that the differences arise. These
reclassifications, which have no impact on net asset value of the Fund, are
primarily attributable to distribution reclass, expiration of capital loss
carryforwards, and tax treatment of paydown gain (loss) on mortgage and
asset-backed securities.

The tax character of dividends and distributions during the last two fiscal

Money Market Fund                                              $4


The Government II Fund and GNMA Fund have permanent book/tax differences due to
the expiration of capital loss carryforwards. The Government II Fund and GNMA
Fund have $68,745 and $414,209 of capital losses, respectively, which have
expired as of January 31, 2005.

For Federal income tax purposes, capital loss carryforwards may be carried
forward and applied against future capital gains. Post-October losses represent
losses realized on investment transactions from November 1, 2004 through January
31, 2005 that, in accordance with Federal income tax regulations, the Funds may
elect to defer and treat as having arisen in the following fiscal year.

At July 31, 2005 the Money Market Funds cost of securities for Federal income
tax purposes approximates the cost located in the Statement of Net Assets.

The Federal tax cost and aggregate gross unrealized appreciation and
depreciation on investments held by the Fixed Income Funds at July 31, 2005,
were as follows:

7. INVESTMENT RISKS

In the normal course of business, the Funds enter into contracts that provide
general indemnifications by the Fund to the counterparty to the contract. The
Funds' maximum exposure under these arrangements is dependent on future claims
that may be made against the Funds and, therefore, cannot be established;
however, based on experience, the risk of loss from such claim is considered
remote.


8. SUBSEQUENT EVENT

The Board of Trustees (the "Board") has selected KPMG LLP (KPMG) to serve as the
Trust's independent registered public accounting firm for the Trust's fiscal
year ending January 31, 2006. The decision to select KPMG was recommended by the
Audit Committee and was approved by the Board on September 19, 2005.

The selection of KPMG does not reflect any disagreements with or dissatisfaction
by the Trust or the Board with the performance of the Trust's prior auditor.
Rather, this change was approved by the Board upon the Audit Committee's
recommendation of KPMG.

================================================================================

SEI DAILY INCOME TRUST -- JULY  31, 2005



Disclosure of Fund Expenses (Unaudited)

All mutual funds have operating expenses. As a shareholder of a Fund, your
investment is affected by these ongoing costs, which include (among others)
costs for portfolio management, administrative services, and shareholder reports
like this one. It is important for you to understand the impact of these costs
on your investment returns.

Operating expenses such as these are deducted from the Fund`s gross income and
directly reduce your final investment return. These expenses are expressed as a
percentage of the Fund's average net assets; this percentage is known as the
Fund's expense ratio.

The following examples use the expense ratio and are intended to help you
understand the ongoing costs (in dollars) of investing in your Fund and to
compare these costs with those of other mutual funds. The examples are based on
an investment of $1,000 made at the beginning of the period shown and held for
the entire period.

The table on the next page illustrates your Fund's costs in two ways:

o ACTUAL FUND RETURN. This section helps you to estimate the actual expenses
that your Fund incurred over the period. The "Expenses Paid During Period"
column shows the actual dollar expense cost incurred by a $1,000 investment in
the Fund, and the "Ending Account Value" number is derived from deducting that
expense cost from the fund's gross investment return.

You can use this information, together with the actual amount you invested in
the fund, to estimate the expenses your Fund incurred over that period. Simply
divide your actual starting account value by $1,000 to arrive at a ratio (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply that
ratio by the number shown for your Fund under "Expenses Paid During Period."

o HYPOTHETICAL 5% RETURN. This section helps you compare your Fund's costs with
those of other mutual funds. It assumes that the fund had an annual 5% return
before expenses during the year, but that the expense ratio (Column 3) is
unchanged. This example is useful in making comparisons because the Securities
and Exchange Commission requires all mutual funds to make this 5% calculation.
You can assess your Fund's comparative cost by comparing the hypothetical result
for your Fund in the "Expense Paid During Period" column with those that appear
in the same charts in the shareholder reports for other funds.

NOTE: Because the return is set at 5% for comparison purposes -- NOT your Fund's
actual return -- the account values shown do not apply to your specific
investment.

SEI Daily Income Trust / Semi-Annual Report / July 31, 2005                   45


================================================================================


Board of Trustees Considerations in Approving the
Continuation of Advisory and Sub-Advisory Agreements

(Unaudited)


The SEI Daily Income Trust ("the Trust") and SEI Investments Management
Corporation ("SIMC") have entered into an investment advisory agreement (the
"Advisory Agreement"). Pursuant to the Advisory Agreement, SIMC oversees the
investment advisory services provided to each series of the Trust (each, a
"Fund" and, collectively, the "Funds") and may manage the cash portion of the
Funds' assets. Pursuant to a separate sub-advisory agreement (the "Sub-Advisory
Agreement" and, together with the Advisory Agreement, the "Investment Advisory
Agreements") with SIMC, and under the supervision of SIMC and the Trust's Board
of Trustees (the "Board"), the Sub-Advisers are responsible for the day-to-day
investment management of all or a discrete portion of the assets of the Funds.
The Sub-Advisers also are responsible for managing their employees who provide
services to these Funds. The Sub-Advisers are selected based primarily upon the
research and recommendations of SIMC, which evaluates quantitatively, and
qualitatively each Sub-Adviser's skills and investment results in managing
assets for specific asset classes, investment styles and strategies.

The Investment Company Act of 1940, as amended (the "1940 Act") requires that
the initial approval of, as well as the continuation of, each Fund's Investment
Advisory Agreements must be specifically approved: (i) by the vote of the Board
of Trustees or by a vote of the shareholders of the Fund; and (ii) by the vote
of a majority of the Trustees who are not parties to the Investment Advisory
Agreements or "interested persons" of any party (the "Independent Trustees"),
cast in person at a meeting called for the purpose of voting on such approval.
In connection with their consideration of such approvals, the Fund's Trustees
must request and evaluate, and SIMC and the Sub-Advisers are required to
furnish, such information as may be reasonably necessary to evaluate the terms
of the Investment Advisory Agreements. In addition, the Securities and Exchange
Commission ("SEC") takes the position that, as part of their fiduciary duties
with respect to a mutual fund's fees, mutual fund boards are required to
evaluate the material factors applicable to a decision to approve an Investment
Advisory Agreement.

Consistent with these responsibilities, the Trust's Board of Trustees calls and
holds meetings each year that are dedicated to considering whether to renew the
Investment Advisory Agreements between the Trust and SIMC and SIMC and each of
the Sub-Advisers with respect to the Funds of the Trust. In preparation for
these meetings, the Board requests and reviews a wide variety of materials
provided by SIMC and the Sub-Advisers, including information about SIMC's and
the Sub-Advisers' affiliates, personnel and operations. The Board also receives
extensive data provided by third parties. This information is in addition to the
detailed information about the Funds that the Board reviews during the course of
each year, including information that relates to Fund operations and Fund
performance. The Trustees also receive a memorandum from Fund counsel and
independent counsel to the Independent Trustees regarding the responsibilities
of Trustees in connection with their consideration of whether to approve the
Trust's Investment Advisory Agreements. Finally, the Independent Trustees
receive advice from independent counsel to the Independent Trustees, meet in
executive session outside the presence of Fund management and participate in
question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, the Board requested and received written materials from SIMC and
each Sub-Adviser regarding: (a) the quality of SIMC's and Sub-Advisers'
investment management and other services; (b) SIMC's and Sub-Advisers'
investment management personnel; (c) SIMC's and Sub-Advisers' operations and
financial condition; (d) SIMC's and Sub-Advisers' brokerage practices (including
any soft dollar arrangements) and investment strategies; (e) the level of the
advisory fees that SIMC and each Sub-Adviser charges a Fund compared with the
fees each charges to comparable mutual funds; (f) a Fund's overall fees and
operating expenses compared with similar mutual funds; (g) the level of SIMC's
and each Sub-Adviser's profitability from its Fund-related operations; (h)
SIMC's and Sub-Advisers' compliance systems; (i) SIMC's and Sub-Advisers'
policies on and compliance procedures for personal securities transactions; (j)
SIMC's and Sub-Advisers' reputation, expertise and resources in domestic and/or
international financial markets; and (k) each Fund's performance compared with
similar mutual funds.

At the March 9, 2005 meeting of the Board of Trustees, the Trustees, including a
majority of the Independent Trustees, approved the Investment Advisory
Agreements and approved the selection of SIMC and the Sub-Advisers to act in
their respective capacities for the Funds. The Board's approval was based on its
consideration and evaluation of a variety of specific factors discussed at the
meetings and at prior meetings, including:

   o the nature,  extent and quality of the services provided to the Funds under
     the Investment Advisory Agreements, including the resources of SIMC and the
     Sub-Advisers and their affiliates dedicated to the Funds;

   o each  Fund's  investment  performance  and how it compared to that of other
     comparable mutual funds;


- --------------------------------------------------------------------------------
46                   SEI Daily Income Trust / Semi-Annual Report / July 31, 2005


================================================================================




   o each Fund's expenses under each Investment Advisory Agreement and how those
     expenses compared to those of other comparable mutual funds;

   o the  profitability  of SIMC and the  Sub-Advisers and their affiliates with
     respect to each Fund,  including both direct and indirect benefits accruing
     to SIMC and the Sub-Advisers and their affiliates; and

   o the extent to which  economies of scale would be realized as the Funds grow
     and whether fee levels in the Investment  Advisory Agreements reflect those
     economies of scale for the benefit of Fund investors.

NATURE, EXTENT AND QUALITY OF SERVICES. The Board of Trustees considered the
nature, extent and quality of the services provided by SIMC and the Sub-Advisers
to the Funds and the resources of SIMC and the Sub-Advisers and their affiliates
dedicated to the Funds. In this regard, the Trustees evaluated, among other
things, SIMC's and the Sub-Advisers' personnel, experience, track record and
compliance program. Following evaluation, the Board concluded that, within the
context of its full deliberations, the nature, extent and quality of services
provided by SIMC and the Sub-Advisers to the Funds and the resources of SIMC and
the Sub-Advisers and their affiliates dedicated to the Funds supported renewal
of the Investment Advisory Agreements.

FUND PERFORMANCE. The Board of Trustees considered Fund performance in
determining whether to renew the Investment Advisory Agreements. Specifically,
the Trustees considered each Fund's performance relative to its peer group and
appropriate indices/benchmarks, in light of total return, yield and market
trends. As part of this review, the Trustees considered the composition of the
peer group and selection criteria. In evaluating performance, the Trustees
considered both market risk and shareholder risk expectations for a given Fund.
Following evaluation, the Board concluded that, within the context of its full
deliberations, the performance of the Funds supported renewal of the Investment
Advisory Agreements.

FUND EXPENSES. With respect to the Funds' expenses under the Investment Advisory
Agreements, the Trustees considered the rate of compensation called for by the
Investment Advisory Agreements and each Fund's net operating expense ratio in
comparison to those of other comparable mutual funds. The Trustees also
considered information about average expense ratios of comparable mutual funds
in each Fund's respective peer group. Finally, the Trustees considered the
effects of SIMC's voluntary waiver of management and other fees and the
Sub-Advisers' fees to prevent total Fund expenses from exceeding a specified cap
and that SIMC and the Sub-Advisers, through waivers, have maintained the Funds'
net operating expenses at competitive levels for their respective distribution
channels. Following evaluation, the Board concluded that, within the context of
its full deliberations, the expenses of the Funds are reasonable and supported
renewal of the Investment Advisory Agreements.

PROFITABILITY. With regard to profitability, the Trustees considered all
compensation flowing to SIMC and the Sub-Advisers and their affiliates, directly
or indirectly. The Trustees considered whether the varied levels of compensation
and profitability under the Investment Advisory Agreements and other service
agreements were reasonable and justified in light of the quality of all services
rendered to the Funds by SIMC and the Sub-Advisers and their affiliates. Based
on this evaluation, the Board concluded that, within the context of its full
deliberations, the profitability of SIMC and the Sub-Advisers is reasonable and
supported renewal of the Investment Advisory Agreements.

ECONOMIES OF SCALE. The Trustees considered the existence of any economies of
scale and whether those were passed along to a Fund's shareholders through a
graduated investment advisory fee schedule or other means, including any fee
waivers by SIMC and its affiliates. Based on this evaluation, the Board
concluded that, within the context of its full deliberations, the Funds obtain
reasonable benefit from economies of scale.

Based on the Trustees' deliberation and their evaluation of the information
described above, the Board, including all of the Independent Trustees,
unanimously approved the continuation of the Investment Advisory Agreements and
concluded that the compensation under the Investment Advisory Agreements is fair
and reasonable in light of such services and expenses and such other matters as
the Trustees considered to be relevant in the exercise of their reasonable
judgment. In the course of their deliberations, the Trustees did not identify
any particular information that was all-important or controlling.
