EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME FUND as of August 31, 2004

LETTER TO SHAREHOLDERS

[PHOTO OF THOMAS E. FAUST JR.]

Thomas E. Faust Jr.
President

We are pleased to welcome shareholders of Eaton Vance Tax-Advantaged Dividend
Income Fund (the "Fund"), a closed-end fund traded on the New York Stock
Exchange under the symbol EVT, with the Fund's first annual report. Among the
first equity income funds designed to take advantage of new favorable tax rates
on dividend income, the Fund's investment objective is to provide a high level
of after-tax total return, consisting primarily of tax-advantaged dividend
income and capital appreciation. The Fund invests primarily in a diversified
portfolio of common and preferred stocks that pay dividends that qualify for
federal income taxation at long-term capital gains rates.

Based on net asset value (NAV) per share for the period from inception on
September 30, 2003, through August 31, 2004, the Fund had a total return of
16.84%. This return resulted from an increase in NAV from $19.10 (offering
price, less all commissions and fees) on September 30, 2003, to $21.14 on August
31, 2004, and the distribution of $1.075 per share in dividend income.(1)

Based on share price trading on the New York Stock Exchange for the period from
inception on September 30, 2003, through August 31, 2004, the Fund had a total
return of 5.67%. This return resulted from an increase in share price from
$19.10 (offering price, less all commissions and fees) on September 30, 2003, to
$19.12 on August 31, 2004, and the distribution of $1.075 per share in dividend
income.(1) Based on the most recent dividend and a share price of $19.12, the
Fund had a market yield of 6.75% as of August 31, 2004.(2)

WITH TODAY'S LOWER TAX RATES, IT IS STILL IMPORTANT FOR INVESTORS TO CONSIDER
TAX EFFECTS...

Last year, Congress passed legislation that included several provisions that
affect individual investors. The most important aspects of the Jobs and Growth
Tax Relief Reconciliation Act of 2003 for individuals were a lowering of tax
rates for ordinary income and long-term capital gains and a change in the tax
treatment of qualifying dividend income, which is now taxed at the same rates as
long-term capital gains, rather than as ordinary income.

The biggest change for equity investors is that qualifying dividend income is
now taxed at much lower rates than other investment income and short-term gains
(maximum rate of 15% vs. 35%). The spread between short-term and long-term
capital gains tax rates has also increased. These changes increase the
importance of achieving a mix of returns that emphasizes long-term gains and
qualifying dividends over less favorably taxed short-term gains and
non-qualifying dividends and other investment income.

Taxes continue to be the single largest cost borne by long-term equity
investors. Strategies to help minimize tax effects can add real value to taxable
accounts. Just as before, it makes sense for taxpayers to invest in funds that
share their objective of after-tax returns.


                                                    Sincerely,

                                                    /s/ Thomas E. Faust Jr.

                                                    Thomas E. Faust Jr.
                                                    President

MANAGEMENT DISCUSSION

AN INTERVIEW WITH MICHAEL R. MACH, JUDITH A. SARYAN, AND THOMAS H. LUSTER,
PORTFOLIO MANAGERS OF EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME FUND


[PHOTO OF MICHAEL R. MACH, CFA]

Michael R. Mach, CFA
Portfolio Manager

Q: Michael, would you describe the economic and market environment since the
   Fund's inception on September 30, 2003?

A: MR. MACH: Since the Fund's inception 11 months ago, the U.S. economy has
   shown above-trend growth, driven by stimulative monetary and fiscal policy,
   improving consumer confidence and a healthier employment picture. At the same
   time, inflation has been generally on the increase, albeit rising slowly from
   very low levels back toward the long-term average. Against this generally
   positive economic backdrop, equity markets scored solid gains.

   During the 11-month period ending August 31, 2004, the Fund provided
   shareholders a total return of 16.84% on a net asset value (NAV) basis and
   5.67% based on share price.* For comparative purposes, over this same period,
   the Russell 1000 Value Index and the Merrill Lynch Preferred Index had total
   returns of 18.68% and 5.04%, respectively.(1)

Judith A. Saryan, CFA
Portfolio Manager

Q: Judith, could you discuss how the Fund has been invested over the past 11
   months?

A: MS. SARYAN: Based on the Fund's objective of providing a high level of
   after-tax total return, consisting primarily of tax-advantaged dividend
   income and capital appreciation, the Fund was primarily invested in
   securities that generated a relatively high level of qualifying dividend
   income (QDI). At the end of the period, the Fund had approximately 69.0% of
   total investments invested in common stocks, approximately 30.3% of total
   investments invested in preferred stocks, and 0.7% of total investments held
   in cash equivalents. Within the common stock portfolio, the Fund had 34.1% of
   total investments invested in utility and telecommunication stocks. An
   additional 34.9% of the Fund's total investments were invested in common
   stocks diversified across the consumer, industrial and financial sectors.(2)

Q: Judith, how would you characterize the performance of the Fund's utility and
   telecommunication common stocks over this period?

A: MS. SARYAN: The utility and telecommunication stocks owned by the Fund
   generally outperformed the overall markets for the 11-month period ending
   August 31, 2004. Utility stocks rose during this period as longterm interest
   rates declined. Historically, utility, telecommunication and other higher
   yielding stocks have tended to do well during periods of declining long-term
   interest rates. Also throughout this period, many of the utility and
   telecommunication companies owned by the Fund experienced strong free cash
   flow generation. This allowed many of the Fund's utility and
   telecommunication holdings to increase their regular quarterly, semi-annual
   or annual dividend payments. In a number of cases, companies held in the
   Fund's portfolio also rewarded shareholders with special one-time dividend
   payments.

(2) Holdings are subject to change due to active management.

Thomas H. Luster, CFA
Portfolio Manager

Q: Michael, would you comment on the performance of the Fund's other common
   stock holdings?

A: MR. MACH: In addition to the utility and telecommunication stocks mentioned
   above, the Fund also benefited from being invested in a broadly diversified
   basket of other dividend-paying common stocks. Consumer-related stocks held
   by the Fund generally moved higher during the period, as consumer spending
   benefited from tax rebates and strong new job creation. Growing demand and
   increasing commodity prices generally benefited the Fund's holdings in the
   energy and material sectors. And as improving corporate earnings and free
   cash flow began to fuel a rebound in business spending, industrial stocks
   held by the Fund also generally benefited.

Q: Tom, could you comment on the performance of the Fund's preferred stocks?

A: MR. LUSTER: During the period, preferred stocks owned by the Fund generated
   mid-single digit returns. The performance of the Fund's preferred stock
   holdings generally followed fixed-income benchmarks during the period,
   posting positive returns during periods of stable or falling interest rates,
   and negative returns during periods when yields moved higher. During the last
   11 months, the volatility associated with owning preferred stocks was greater
   than usual. The Fund's disciplined and research-intensive approach to
   managing its preferred portfolio allowed it to navigate successfully through
   this period of unusual volatility

Q: Judith, has the Fund invested in any non-U.S. securities since its 9/30/03
   inception?

A: MS. SARYAN: Yes, the Fund has invested in non-U.S. securities in both its
   common and preferred portfolios. These investments have provided the Fund
   with international diversification and dividend yields often more attractive
   than the yields available on stocks issued by similar domestic corporations.
   As of August 31, 2004, approximately 23.4% of the Fund's total investments
   were invested in non-US common stocks. In addition, approximately 16.9% of
   the Fund's total investments were invested in "Yankee" preferreds, preferred
   stocks generally issued by large, highly rated, European financial
   institutions but denominated in U.S. dollars.(1)

Q: Tom, are there any unifying themes tying together Fund investments?

A: MR. LUSTER: Definitely. Our discipline is to buy dividend-paying stocks,
   whether common or preferred, of companies characterized by strong business
   franchises, backed by proven management teams and solid balance sheets. For
   common stocks, we focus on companies that offer the potential for growth in
   earnings, cash flow and dividends. For preferreds, we have generally favored
   highly-rated, higher-yielding securities.

Q: Michael, have a significant number of the Fund's common stock holdings raised
   their dividends since the Fund's inception?

A: MR. MACH: Yes. In fact, a majority of the Fund's common stock holdings raised
   their dividends during this period. The Jobs and Growth Tax Reconciliation
   Act of 2003 that President Bush signed into law in May of 2003 effectively
   removed many of the disincentives previously associated with paying out
   earnings as dividends. This has set the stage for the increases in dividend
   payouts now emerging. We believe the growing number of dividend increases we
   have seen in recent months also reflects companies achieving higher profits
   and, in some cases, divesting non-core investments. This has provided greater
   free cash flow that has been used by corporations to increase the dividends
   paid to shareholders.


(1) Holdings are subject to change due to active management.

                                        4
<Page>

Q: Judith, could you describe how the Fund's dividend capture strategy helps it
   to generate incremental qualified dividend income?

A: MS. SARYAN: The Fund's dividend capture strategy is a trading strategy
   designed to enhance the level of qualified, tax-advantaged dividend income
   earned by the Fund. By implementing its dividend capture strategy, the Fund
   has been able to collect a greater number of dividend payments over the last
   11 months than it would have collected by simply adhering to a buy-and-hold
   strategy.

   On September 15, 2004, the Fund announced an increase in its monthly dividend
   from $0.1075 per share to $0.1100 per share. This increase reflected both the
   effective implementation of the Fund's dividend capture strategy and the
   significant number of dividend increases by companies represented in the
   Fund's common stock portfolio.(1)

Q: Judith, is it your expectation that all of the dividend income paid out by
   the Fund will be QDI income through the end of 2004?

A: MS. SARYAN: At this point, we anticipate that virtually all of the income
   paid out by the Fund will be considered QDI income, subject to taxation at
   long-term capital gains rates no greater than 15%.

Q: Tom, would you review how the Fund has managed the maturities of the Auction
   Preferred Shares (APS) that it has issued to leverage its initial assets?

A: MR. LUSTER: Since the Fund initially issued its APS in December 2003, we have
   on a number of occasions moved to extend the maturities of these issues. As
   of September 23, 2004, the Fund's $700 million in APS borrowings maintained a
   weighted average maturity of 121 days. This compares against a weighted
   average maturity of 21 days when the APS were first issued. By lengthening
   the maturity of the Fund's APS in this manner, we believe the Fund has
   lowered its sensitivity to rising short-term interest rates. Use of financial
   leverage creates an opportunity for increased income, but, at the same time,
   creates special risks (including the likelihood of greater volatility of net
   asset value and market price of the common shares).

Q: Michael, do you have any final comments for our shareholders?

A: MR. MACH: In recent months, driven by a combination of the lower tax rate
   applied to qualifying dividend income, strong corporate earnings and free
   cash flow growth, and historically low dividend payout ratios, corporations
   have meaningfully increased dividend payments made to shareholders of common
   stock. We believe the Fund is positioned to benefit should this trend
   continue.

(1)  For the period from the start of business, September 30, 2003, to
     August 31, 2004.

(2)  Computed using average common shares outstanding.

(3)  Net asset value at beginning of period reflects the deduction of the sales
     load of $0.900 per share paid by the shareholder from the $20.00 offering
     price.

(4)  Total investment return on net asset value is calculated assuming a
     purchase at the offering price of $20.00 less the sales load of $0.90 per
     share paid by the shareholder on the first day and a sale at the net aset
     value on the last day of the period reported. Total investment return on
     market value is calculated assuming a purchase at the offering price of
     $20.00 less the sales load of $0.90 per share paid by the shareholder on
     the first day and a sale at the current market price on the last day of the
     period reported. Total investment return on net asset value and total
     investment return on market value are not computed on an annualized basis.

(5)  Ratios do not reflect the effect of dividend payments to preferred
     shareholders. Ratios to average net assets applicable to common shares
     reflect the Fund's leveraged capital structure.

EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME FUND as of August 31, 2004

NOTES TO FINANCIAL STATEMENTS

1  SIGNIFICANT ACCOUNTING POLICIES

   Eaton Vance Tax-Advantaged Dividend Income Fund (the Fund) is registered
   under the Investment Company Act of 1940, as amended, as a diversified,
   closed-end management investment company. The Fund was organized under the
   laws of the Commonwealth of Massachusetts by an Agreement and Declaration of
   Trust dated July 10, 2003. The Fund's investment objective is to provide a
   high level of after-tax total return consisting primarily of tax-advantaged
   dividend income and capital appreciation. The Fund pursues its objective by
   investing primarily in dividend-paying common and preferred stocks. The
   following is a summary of significant accounting policies consistently
   followed by the Fund in the preparation of its financial statements. The
   policies are in conformity with accounting principles generally accepted in
   the United States of America.

   A INVESTMENT VALUATION -- Securities listed on a U.S. securities exchange
   generally are valued at the last sale price on the day of valuation or, if no
   sales took place on such date, at the mean between the closing bid and asked
   prices therefore on the exchange where such securities are principally
   traded. Equity securities listed on the NASDAQ National Market System
   generally are valued at the official NASDAQ closing price. Unlisted or listed
   securities for which closing sales prices or closing quotations are not
   available are valued at the mean between the latest available bid and asked
   prices or, in the case of preferred equity securities that are not listed or
   traded in the over-the-counter market, by an independent pricing service. The
   value of preferred equity securities that are valued by a pricing service on
   a bond basis will be adjusted by an income factor, to be determined by the
   investment adviser, to reflect the next anticipated regular dividend.
   Exchange-traded options are valued at the last sale price for the day of
   valuation as quoted on the principal exchange or board of trade on which the
   options are traded or, in the absence of sales on such date, at the mean
   between the latest bid and asked prices therefore. Futures positions on
   securities and currencies generally are valued at closing settlement prices.
   Short-term debt securities with a remaining maturity of 60 days or less are
   valued at amortized cost. If short-term debt securities were acquired with a
   remaining maturity of more than 60 days, their amortized cost value will be
   based on their value on the sixty-first day prior to maturity. Other fixed
   income and debt securities, including listed securities and securities for
   which price quotations are available, will normally be valued on the basis of
   valuations furnished by a pricing service. The daily valuation of foreign
   securities generally is determined as of the close of trading on the
   principal exchange on which such securities trade. Events occurring after the
   close of trading on foreign exchanges may result in adjustments to the
   valuation of foreign securities to more accurately reflect their fair value
   as of the close of regular trading on the New York Stock Exchange. The Fund
   may rely on an independent fair valuation service in adjusting the valuations
   of foreign securities. Foreign securities and currencies are valued in U.S.
   dollars, based on foreign currency exchange rate quotations supplied by an
   independent quotation service. Investments held by the Fund for which
   valuations or market quotations are unavailable are valued at fair value
   using methods determined in good faith by or at the direction of the Trustees
   of the Fund considering relevant factors, data and information including the
   market value of freely tradable securities of the same class in the principal
   market on which such securities are normally traded.

   B INCOME -- Dividend income is recorded on the ex-dividend date for dividends
   received in cash and/or securities. However, if the ex-dividend date has
   passed, certain dividends from foreign securities are recorded as the Fund is
   informed of the ex-dividend date. Interest income is recorded on the accrual
   basis.

   C FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
   Internal Revenue Code applicable to regulated investment companies and to
   distribute to shareholders each year all of its taxable income, including any
   net realized gain on investments. Accordingly, no provision for federal
   income or excise tax is necessary. At August 31, 2004, the Fund, for federal
   income tax purposes, had a capital loss carryover of $3,388,959, which will
   reduce the Fund's taxable income arising from future net realized gain on
   investments, if any, to the extent permitted by the Internal Revenue Code,
   and thus will reduce the amount of distributions to shareholders which would
   otherwise be necessary to relieve the Fund of any liability for federal
   income or excise tax. Such capital loss carryover will expire August 31,
   2012. Additionally, at August 31, 2004, the Fund had net capital losses of
   $15,134,158 attributable to security transactions incurred after October 31,
   2003. These capital losses are treated as arising on the first day of the
   Fund's taxable year ended August 31, 2005.

   D OFFERING COSTS -- Costs incurred by the Fund in connection with the
   offering of the common shares and preferred shares were recorded as a
   reduction of capital paid in excess of par applicable to common shares.

                                       14
<Page>

   E WRITTEN OPTIONS -- Upon the writing of a call or a put option, an amount
   equal to the premium received by the Fund is included in the Statement of
   Assets and Liabilities as a liability. The amount of the liability is
   subsequently marked-to-market to reflect the current value of the option
   written in accordance with the Fund's policies on investment valuations
   discussed above. Premiums received from writing options which expire are
   treated as realized gains. Premiums received from writing options which are
   exercised or are closed are added to or offset against the proceeds or amount
   paid on the transaction to determine the realized gain or loss. If a put
   option is exercised, the premium reduces the cost basis of the securities
   purchased by the Fund. The Fund, as writer of an option, may have no control
   over whether the underlying securities may be sold (call) or purchased (put)
   and, as a result, bears the market risk of an unfavorable change in the price
   of the securities underlying the written option.

   F PURCHASED OPTIONS -- Upon the purchase of a call or put option, the premium
   paid by the Fund is included in the Statement of Assets and Liabilities as an
   investment. The amount of the investment is subsequently marked-to-market to
   reflect the current market value of the option purchased, in accordance with
   the Fund's policies on investment valuations discussed above. If an option
   which the Fund has purchased expires on the stipulated expiration date, the
   Fund will realize a loss in the amount of the cost of the option. If the Fund
   enters into a closing sale transaction, the Fund will realize a gain or loss,
   depending on whether the sales proceeds from the closing sale transaction are
   greater or less than the cost of the option. If a Fund exercises a put
   option, it will realize a gain or loss from the sale of the underlying
   security, and the proceeds from such sale will be decreased by the premium
   originally paid. If the Fund exercises a call option, the cost of the
   security which the Fund purchases upon exercise will be increased by the
   premium originally paid.

   G SWAP AGREEMENTS -- The Fund may enter into swap agreements to hedge against
   fluctuations in securities prices, interest rates or market conditions, to
   change the duration of the overall portfolio, to mitigate non-payment or
   default risk, or to gain exposure to particular securities, baskets of
   securities, indices or currencies. In a standard swap transaction, two
   parties agree to exchange the returns (or differentials in rates of return)
   to be exchanged or swapped between the parties, which returns are calculated
   with respect to a notional amount (i.e., the return on or increase in value
   of a particular dollar amount invested at a particular interest rate or in a
   "basket" of securities representing a particular index). The Fund will enter
   into swaps on a net basis. If the other party to a swap defaults, the Fund's
   risk of loss consists of the net amount of payments that the Fund is
   contractually entitled to receive. The Fund will not enter into any swap
   unless the claims-paying ability of the other party thereto is considered to
   be investment grade by the Adviser. The Fund is exposed to credit loss in the
   event of non-performance by the counterparty. These instruments are traded in
   the over-the-counter market. If the Adviser is incorrect in its forecasts of
   market values, interest rates and other applicable factors, the investment
   performance of the Fund would be unfavorably affected.

   H FOREIGN CURRENCY TRANSLATION -- Investment valuations, other assets, and
   liabilities initially expressed in foreign currencies are converted each
   business day into U.S. dollars based upon current exchange rates. Purchases
   and sales of foreign investment securities and income and expenses are
   converted into U.S. dollars based upon currency exchange rates prevailing on
   the respective dates of such transactions. Recognized gains or losses on
   investment transactions attributable to foreign currency exchange rates are
   recorded for financial statement purposes as net realized gains and losses on
   investments. That portion of unrealized gains and losses on investments that
   results from fluctuations in foreign currency exchange rates is not
   separately disclosed.

   I USE OF ESTIMATES -- The preparation of the 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 income and expense during the
   reporting period. Actual results could differ from those estimates.

   J INDEMNIFICATIONS -- Under the Fund's organizational documents, its officers
   and Trustees may be indemnified against certain liabilities and expenses
   arising out of the performance of their duties to the Fund and shareholders
   are indemnified against personal liability for obligations of the Fund.
   Additionally, in the normal course of business, the Fund enters into
   agreements with service providers that may contain 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.

   K OTHER -- Investment transactions are accounted for on a trade date basis.
   Realized gains and losses are computed on the specific identification of the
   securities sold.

                                       15
<Page>

   L EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
   custodian of the Fund. Pursuant to the custodian agreement, IBT receives a
   fee reduced by credits which are determined based on the average daily cash
   balance the Fund maintains with IBT. All credit balances used to reduce the
   Fund's custodian fees are reported as a reduction of total expenses in the
   Statement of Operations.

2  AUCTION PREFERRED SHARES

   The Fund issued 4,000 shares of Auction Preferred Shares (APS) Series A,
   4,000 shares of APS Series B, 4,000 shares of APS Series C, 4,000 shares of
   APS Series D, 4,000 shares of APS Series E, 4,000 shares of APS Series F and
   4,000 shares of APS Series G on December 10, 2003 in a public offering. The
   underwriting discount and other offering costs were recorded as a reduction
   of the capital of the common shares. Dividends of the APS, which accrue
   daily, are cumulative at a rate which was established at the offering of the
   APS and have been reset by an auction based on the dividend period of each
   Series. Rates are reset weekly for Series A and Series B, annually for
   Series C, Series D and Series F, approximately monthly for Series E and
   approximately bi-monthly for Series G. The reset period for Series C,
   Series D and Series F was changed after the initial public offering for each
   such series. Subsequent to August 31, 2004, the reset period for Series A was
   changed to an annual reset period. Dividends are generally paid on the day
   following the end of the dividend period for Series A, Series B and Series E.
   Series C, Series D, Series F and Series G pay accumulated dividends on the
   first business day of each month and on the day following the end of the
   dividend period.

   Dividend rate ranges for the period from the commencement of the offering,
   December 10, 2003, to August 31, 2004 are as indicated below:

</Table>

   The APS are redeemable at the option of the Fund, at a redemption price equal
   to $25,000 per share, plus accumulated and unpaid dividends on any dividend
   payment date. The APS are also subject to mandatory redemption at a
   redemption price equal to $25,000 per share, plus accumulated and unpaid
   dividends, if the Fund is in default for an extended period on its asset
   maintenance requirements with respect to the APS. If the dividends on the APS
   shall remain unpaid in an amount equal to two full years' dividends, the
   holders of the APS as a class have the right to elect a majority of the Board
   of Trustees. In general, the holders of the APS and the common shares have
   equal voting rights of one vote per share, except that the holders of the
   APS, as a separate class, have the right to elect at least two members of the
   Board of Trustees. The APS have a liquidation preference of $25,000 per
   share, plus accumulated and unpaid dividends. The Fund is required to
   maintain certain asset coverage with respect to the APS as defined in the
   Fund's By-Laws and the Investment Company Act of 1940. The Fund pays an
   annual fee equivalent to 0.25% of the preferred shares' liquidation value for
   the remarketing efforts associated with the preferred auctions.

3  DISTRIBUTION TO SHAREHOLDERS

   The Fund intends to make monthly distributions of net investment income,
   after payment of any dividends on any outstanding Auction Preferred Shares.
   In addition, at least annually, the Funds intends to distribute net capital
   gain, if any. Distributions are recorded on the ex-dividend date. The
   applicable dividend rates for APS on August 31, 2004 are listed below. For
   the period from the commencement of the offering, the amount of dividends
   each Series paid to Auction Preferred shareholders and average APS dividend

   -----------------------------------------------------------------------
</Table>

   (1)  For the period from the commencement of offering, December 10, 2003, to
        August 31, 2004.

   The Fund distinguishes between distributions on a tax basis and a financial
   reporting basis. Accounting principles generally accepted in the United
   States of America require

                                       16
<Page>

   that only distributions in excess of tax basis earnings and profits be
   reported in the financial statements as a return of capital.


   The tax character of the distributions declared for the period from the start
   of business, September 30, 2003, to August 31, 2004, was as follows:

<Table>
<Caption>
                                                           PERIOD ENDED
                                                         AUGUST 31, 2004

   Distributions declared from:

   Ordinary income                                       $    84,978,226
</Table>

   During the period from the start of business, September 30, 2003, to August
   31, 2004, accumulated undistributed net investment income was decreased by
   $1,067,087, and accumulated net realized loss on investments decreased by
   $1,067,087 due to differences between book and tax accounting for investment
   transactions. This change had no effect on the net assets or the net asset
   value per share.

   As of August 31, 2004, the components of distributable earnings (accumulated
   losses) on a tax basis were as follows:

<Table>
                                       
   Undistributed ordinary income          $  16,412,108
   Capital loss carryforwards             $  (3,388,959)
   Unrealized appreciation                $ 166,616,049
   Other temporary differences            $ (22,964,017)
</Table>

4  INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

   The investment adviser fee is earned by Eaton Vance Management (EVM), as
   compensation for management and investment advisory services rendered to the
   Fund. Under the advisory agreement, EVM receives a monthly advisory fee in
   the amount equal to 0.85% annually of average daily gross assets of the Fund.
   For the period from the start of business, September 30, 2003, to August 31,
   2004, the advisory fee amounted to $15,853,685. EVM serves as the
   administrator of the Fund , but currently receives no compensation for
   providing administrative services to the Fund.

   In addition, the Adviser has contractually agreed to reimburse the Fund for
   fees and other expenses in the amount of 0.20% of the average daily gross
   assets for the first five years of the Fund's operations, 0.15% of average
   daily gross assets in year six, 0.10% in year seven and 0.05% in year eight.
   For the period from the start of business, September 30, 2003, to August 31,
   2004 the Investment Adviser waived $3,730,279 of its advisory fee. The
   Adviser has also agreed to reduce the investment adviser fee by an amount
   equal to that portion of commissions paid to broker dealers in execution of
   Fund portfolio transactions that is consideration for third-party research
   services. For the period from May 1, 2004, to August 31, 2004, the Investment
   Adviser waived $21,298 of its advisory fee.

   EVM has agreed to reimburse the Fund for costs incurred in the Fund's
   organization. For the period from the start of business, September 30, 2003,
   to August 31, 2004, EVM reimbursed the Fund $7,500 in organization expenses.

   Trustees of the Fund who are not affiliated with EVM may elect to defer
   receipt of all or a percentage of their annual fees in accordance with the
   terms of the Trustees Deferred Compensation Plan. For the period from the
   start of business, September 30, 2003, to August 31, 2004, no significant
   amounts have been deferred.

   Certain officers and Trustees of the Fund are officers of the above
   organization.

   During the period ended August 31, 2004, the Fund engaged in a sale
   transaction in the amount of $19,988,874 with a Portfolio which utilizes
   Boston Management and Research, a wholly-owned subsidiary of EVM, as
   investment adviser. This sale transaction complied with Rule 17a-7 under the
   Investment Company Act of 1940.

5  PURCHASES AND SALES OF INVESTMENTS

   Purchases and sales of investments, other than short-term obligations,
   aggregated $3,703,900,312 and $1,636,877,076, respectively, for the period
   from the start of business, September 30, 2003, to August 31, 2004.

8  RISKS ASSOCIATED WITH FOREIGN INVESTMENTS

   Investing in securities issued by companies whose principal business
   activities are outside the United States may involve significant risks not
   present in domestic investments. For example, there is generally less
   publicly available information about foreign companies, particularly those
   not subject to the disclosure and reporting requirements of the U.S.
   securities laws. Foreign issuers are generally not bound by uniform
   accounting, auditing, and financial reporting requirements and standards of
   practice comparable to those applicable to domestic issuers. Investments in
   foreign securities also involve the risk of possible adverse changes in
   investment or exchange control regulations, expropriation or confiscatory
   taxation, limitation on the removal of funds or other assets of the Fund,
   political or financial instability or diplomatic and other developments which
   could affect such investments. Foreign stock markets, while growing in volume
   and sophistication, are generally not as developed as those in the United
   States, and securities of some foreign issuers (particularly those in
   developing countries) may be less liquid and more volatile than securities of
   comparable U.S. companies. In general, there is less overall governmental
   supervision and regulation of foreign securities markets, broker-dealers, and
   issuers than in the United States.

9  FINANCIAL INSTRUMENTS

   The Fund may trade in financial instruments with off-balance sheet risk in
   the normal course of its investing activities to assist in managing exposure
   to various market risks. These financial instruments include written options,
   forward foreign currency exchange contracts, and financial futures contracts
   and may involve, to a varying degree, elements of risk in excess of the
   amounts recognized for financial statement purposes. The notional or
   contractual amounts of these instruments represent the investment the Fund
   has in particular classes of financial instruments and does not necessarily
   represent the amounts potentially subject to risk. The measurement of the
   risks associated with these instruments is meaningful only when all related
   and offsetting transactions are considered. The Fund did not have any open
   obligations under these financial instruments at August 31, 2004.

EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME FUND as of August 31, 2004

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE TRUSTEES AND SHAREHOLDERS OF EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME
FUND:

We have audited the accompanying statement of assets and liabilities of Eaton
Vance Tax-Advantaged Dividend Income Fund (the "Fund"), including the portfolio
of investments, as of August 31, 2004, and the related statement of operations,
the statements of changes in net assets, and the financial highlights for the
period from the start of business September 30, 2003, to August 31, 2004. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit.

We conducted our audit in accordance with 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. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned at August 31, 2004 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights present
fairly, in all material respects, the financial position of the Eaton Vance
Tax-Advantaged Dividend Income Fund at August 31, 2004, the results of its
operations, the changes in its net assets and the financial highlights from the
start of business, September 30, 2003, to August 31, 2004, in conformity with
accounting principles generally accepted in the United States of America.

EATON VANCE TAX-ADVANTAGED DIVIDEND INCOME FUND

DIVIDEND REINVESTMENT PLAN

The Fund offers a dividend reinvestment plan (the Plan) pursuant to which
shareholders may elect to have dividends and capital gains distributions
automatically reinvested in common shares (the Shares) of the Fund. You may
elect to participate in the Plan by completing the Dividend Reinvestment Plan
Application Form. If you do not participate, you will receive all distributions
in cash paid by check mailed directly to you by PFPC Inc. as dividend paying
agent. On the distribution payment date, if the net asset value per Share is
equal to or less than the market price per Share plus estimated brokerage
commissions then new Shares will be issued. The number of Shares shall be
determined by the greater of the net asset value per Share or 95% of the market
price. Otherwise, Shares generally will be purchased on the open market by the
Plan Agent. Distributions subject to income tax (if any) are taxable whether or
not shares are reinvested. If your shares are in the name of a brokerage firm,
bank, or other nominee, you can ask the firm or nominee to participate in the
Plan on your behalf. If the nominee does not offer the Plan, you will need to
request that your shares be re-registered in your name with the Fund's transfer
agent, PFPC, Inc. or you will not be able to participate.

The Plan Agent's service fee for handling distributions will be paid by the
Fund. Each participant will be charged their pro rata share of brokerage
commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Plan
Agent at the address noted on the following page. If you withdraw, you will
receive shares in your name for all Shares credited to your account under the
Plan. If a participant elects by written notice to the Plan Agent to have the
Plan Agent sell part or all of his or her Shares and remit the proceeds, the
Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from
the proceeds.

If you wish to participate in the Plan and your shares are held in your own
name, you may complete the form on the following page and deliver it to the Plan
Agent.

Any inquires regarding the Plan can be directed to the Plan Agent, PFPC, Inc.,
at 1-800-331-1710.

<Table>
<Caption>
FISCAL YEAR ENDED                    8/31/2004
- ----------------------------------------------
                                  
Audit Fees                           $  67,362

Audit-Related Fees(1)                $  34,505

Tax Fees(2)                          $   8,000

All Other Fees(3)                    $       0
                                     ---------
Total                                $ 109,867
                                     =========
</Table>

(1)  Audit-related fees consist of the aggregate fees billed for assurance and
     related services that are reasonably related to the performance of the
     audit of financial statements and are not reported under the category of
     audit fees and specifically includes fees for the performance of certain
     agreed-upon procedures relating to the registrant's auction preferred
     shares.

<Page>

(2)  Tax fees consist of the aggregate fees billed for professional services
     rendered by the principal accountant relating to tax compliance, tax
     advice, and tax planning and specifically include fees for tax return
     preparation.
(3)  All other fees consist of the aggregate fees billed for products and
     services provided by the principal accountant other than audit,
     audit-related, and tax services.

During the fiscal year ended August 31, 2004, $35,000 was billed by Deloitte &
Touche LLP, the registrant's principal accountant, for work done in connection
with its Rule 17Ad-13 examination of Eaton Vance Management's assertion that it
has maintained an effective internal control structure over the sub-transfer
agent and registrar functions, such services being pre-approved in accordance
with Rule 2-01(c) (7) (ii) of Regulation S-X.

(e)(1) The registrant's audit committee has adopted policies and procedures
relating to the pre-approval of services provided by the registrant's principal
accountant (the "Pre-Approval Policies"). The Pre-Approval Policies establish a
framework intended to assist the audit committee in the proper discharge of its
pre-approval responsibilities. As a general matter, the Pre-Approval Policies
(i) specify certain types of audit, audit-related, tax, and other services
determined to be pre-approved by the audit committee; and (ii) delineate
specific procedures governing the mechanics of the pre-approval process,
including the approval and monitoring of audit and non-audit service fees.
Unless a service is specifically pre-approved under the Pre-Approval Policies,
it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services
pre-approved therein must be reviewed and ratified by the registrant's audit
committee at least annually. The registrant's audit committee maintains full
responsibility for the appointment, compensation, and oversight of the work of
the registrant's principal accountant.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the
registrant's audit committee pursuant to the "de minimis exception" set forth in
Rule 2-01(c)(7)(i)(C) of Regulation S-X.

(f) Not applicable.

(g) Aggregate non-audit fees (i.e., fees for audit-related, tax, and other
services) billed by the registrant's principal accountant for services rendered
to the registrant for it's fiscal year ended August 31, 2004 were $42,505.
Aggregate non-audit fees (i.e., fees for audit-related, tax, and other services)
billed by the registrant's principal accountant for services rendered to the
Eaton Vance organization (which includes the registrant's investment adviser and
any entity controlling, controlled by, or under common control with the adviser
that provides ongoing services to the registrant) for the registrant's first
fiscal year ended August 31, 2004 were $291,084.

(h) The registrant's audit committee has considered whether the provision by the
registrant's principal accountant of non-audit services to the registrant's
investment adviser and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the registrant that
were not pre-approved pursuant to Rule 2-01(c) (7) (ii) of Regulation S-X is
compatible with maintaining the principal accountant's independence.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

in accordance with Section 3(a)(58)(A) of the Securities and Exchange Act of
1934, as amended. Norton H. Reamer (Chair), Samuel L. Hayes, III, William H.
Park and Lynn A. Stout are the members of the registrant's audit committee.

ITEM 6. SCHEDULE OF INVESTMENTS

Please see schedule of investments contained in the Report to Stockholders
included under Item 1 of this Form N-CSR.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES

The Board of Trustees of the Trust has adopted a proxy voting policy and
procedure (the "Fund Policy"), pursuant to which the Trustees have delegated
proxy voting responsibility to the Fund's investment adviser and adopted the
investment adviser's proxy voting policies and procedures (the "Policies") which
are described below. The Trustees will review the Fund's proxy voting records
from time to time and will annually consider approving the Policies for the
upcoming year. In the event that a conflict of interest arises between the
Fund's shareholders and the investment adviser, the administrator, or any of
their affiliates or any affiliate of the Fund, the investment adviser will
generally refrain from voting the proxies related to the companies giving rise
to such conflict until it consults with the Board of the Fund except as
contemplated under the Fund Policy. The Board's Special Committee will instruct
the investment adviser on the appropriate course of action.

The Policies are designed to promote accountability of a company's management to
its shareholders and to align the interests of management with those
shareholders. The investment adviser will generally support company management
on proposals relating to environmental and social policy issues and on matters
regarding the state of organization of the company. On all other matters, the
investment adviser will take management's proposals under advisement but will
consider each matter in light of the guidelines set forth in the Policies.
Except in the instance of routine matters related to corporate administration
which are not expected to have a significant economic impact on the company or
its shareholders (on which the investment adviser will routinely vote with
management), the investment adviser will review each matter on a case-by-case
basis and reserves the right to deviate from the Policies guidelines when it
believes the situation warrants such a deviation. The Policy includes voting
guidelines for matters relating to, among other things, the election of
directors, approval of independent auditors, executive compensation, corporate
structure and anti-takeover defenses. The investment adviser may abstain from
voting from time to time where it determines that the costs associated with
voting a proxy outweighs the benefits derived from exercising the right to vote.

In addition, the investment adviser will monitor situations that may result in a
conflict of interest between the Fund's shareholders and the investment adviser,
the administrator, or any of their affiliates

<Page>

or any affiliate of the Fund by maintaining a list of significant existing and
prospective corporate clients. The investment adviser's personnel responsible
for reviewing and voting proxies on behalf of the Fund will report any proxy
received or expected to be received from a company included on that list to the
investment adviser's general counsel or chief equity investment officer. The
general counsel or chief equity investment officer will determine if a conflict
exists. If a conflict does exist, the proxy will either be voted strictly in
accordance with the Policy or the investment adviser will seek instruction on
how to vote from the Board.

Effective August 31, 2004, information on how the Fund voted proxies relating to
portfolio securities during the 12 month period ended June 30, 2004 [is/will be]
available (1) without charge, upon request, by calling 1-800-262-1122, and (2)
on the Securities and Exchange Commission's website at http://www.sec.gov.

ITEM 8. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

None

ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

Effective February 9, 2004, the Governance Committee of the Board of Trustees
formalized the procedures by which a Fund's shareholders may recommend nominees
to the registrant's Board of Trustees. The Governance Committee shall, when
identifying candidates for the position of Independent Trustee, consider any
such candidate recommended by a shareholder of a Fund if such recommendation
contains sufficient background information concerning the candidate, and is
received in a sufficiently timely manner (and in any event no later than the
date specified for receipt of shareholder proposals in any applicable proxy
statement with respect to a Fund). Shareholders shall be directed to address any
such recommendations to the attention of the Governance Committee, c/o the
Secretary of the Fund.

ITEM 10. CONTROLS AND PROCEDURES

(a) It is the conclusion of the registrant's principal executive officer and
principal financial officer that the effectiveness of the registrant's current
disclosure controls and procedures (such disclosure controls and procedures
having been evaluated within 90 days of the date of this filing) provide
reasonable assurance that the information required to be disclosed by the
registrant has been recorded, processed, summarized and reported within the time
period specified in the Commission's rules and forms and that the information
required to be disclosed by the registrant has been accumulated and communicated
to the registrant's principal executive officer and principal financial officer
in order to allow timely decisions regarding required disclosure.

(b) There have been no changes in the registrant's internal controls over
financial reporting during the period that has materially affected, or is
reasonably likely to materially affect the registrant's internal control over
financial reporting.
