Commodity Futures Trading Commission Registration

.

 The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

Managed Distribution Plan.

Pursuant to an exemptive order issued by the Securities and Exchange Commission (Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders, stated in terms of a fixed amount per common share.

The Fund currently distributes monthly cash distributions equal to $0.1488 per share in accordance with the MDP. You should not draw any conclusions about the Fund’s investment performance from the amount of these distributions or from the terms of the MDP. The MDP will be subject to regular periodic review by the Fund’s Board of Trustees and the Board may amend or terminate the MDP at any time without prior notice to Fund shareholders. However, at this time there are no reasonably foreseeable circumstances that might cause the termination of the MDP.

The Fund may distribute more than its net investment income and net realized capital gains and, therefore, a distribution may include a return of capital. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” With each distribution, the Fund will issue a notice to shareholders and a press release containing information about the amount and sources of the distribution and other related information. The amounts and sources of distributions contained in the notice and press release are only estimates and are not provided for tax purposes. The amounts and sources of the Fund’s distributions for tax purposes will be reported to shareholders on Form 1099-DIV for each calendar year.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

Economic and Market Conditions

For U.S. equity investors, the 12-month period ended October 31, 2023, was a roller-coaster ride, driven largely by shifting perceptions of whether the U.S. Federal Reserve (the Fed) could bring the world’s largest economy in for a soft landing, and changing expectations of how long interest rates might remain high.

During the opening month of the period, stocks rallied on strong corporate earnings, attractive valuations, and hope the Fed might slow the pace of its interest rate hikes. But in December 2022, equities lost ground as “higher for longer” interest rate fears returned. A continuing irony throughout the period was that good economic news -- record low unemployment, strong job creation, and robust consumer spending -- was viewed as bad news for inflation and fuel for future rate hikes that could weigh on stock prices.

In January 2023, however, U.S. equities began a rally that lasted through July. The initial tailwind was ChatGPT, an artificial intelligence (AI) application that led investors to perceive AI might become the next big innovation to drive the information technology (IT) sector. As a result, IT -- one of the worst-performing sectors in 2022 -- became the standout sector of the first half of 2023. Earlier recession fears that had weighed on stock prices receded as many investors came around to the view that the U.S. economy was doing surprisingly well.

But in the final three months of the period, the bond market halted the stock market’s momentum. As it became clear the Fed would keep rates higher for longer than investors had anticipated just a few months earlier, longer-term bond interest rates rose sharply. Given the potential for relatively attractive returns with lower risk than stocks, many investors shifted from equity assets to bonds. In the final two days of the period, however, signs of a stock rally emerged as investors began to believe the Fed might have reached the end of its monetary tightening cycle.

For the period as a whole, however, U.S. equity performance was solid. The S&P 500® Index, a broad measure of U.S. stocks, returned 10.14%; the blue-chip Dow Jones Industrial Average® returned 3.17%; and the tech-heavy Nasdaq Composite Index returned 17.99%.

Fund Performance

For the 12-month period ended October 31, 2023, Eaton Vance Tax-Advantaged Dividend Income Fund (the Fund) returned -1.99% at net asset value of its common shares (NAV), underperforming its benchmark, the Russell 1000® Value Index (the Index), which returned 0.13%.

The Fund’s common stock allocation underperformed the Index and detracted from returns versus the Index during the period. On an individual stock basis, the largest detractor from Index-relative returns was not owning Index component Meta Platforms, Inc. (Meta), the social media giant behind Facebook, Instagram, and Messenger.

Meta’s stock price more than doubled during the period as its advertising revenues rebounded on improved ad targeting, and profit margins exceeded expectations due to a decrease in spending on longer-term initiatives. The Fund did not own Meta due to concerns that the stock was priced above its fair market value, as well as questions about the sustainability of the company’s earnings.

On a sector basis, stock selections in the communication services, consumer staples, energy, and utilities sectors detracted from performance versus the Index during the period.

In addition, the use of leverage -- which is not employed by the Index -- magnified the negative performance of the Fund’s common stock allocation, hurting returns versus the Index.

In contrast, the largest contributor to Index-relative performance on an individual stock basis was an overweight position in Alphabet, Inc. (Alphabet), Google’s parent company. Alphabet’s share price rose amid accelerating growth across its business divisions and a significant improvement in profit margins. An additional tailwind for Alphabet’s stock price was investor enthusiasm over artificial intelligence (AI), during a period when the company focused on incorporating AI into its products and internal processes. The company’s strong balance sheet also aligned with the Fund’s opportunistic value approach.

On a sector basis, stock selections in health care and information technology contributed to returns versus the Index during the period.

The Fund’s allocation to preferred securities contributed to performance versus the Index as well. The Fund’s preferred allocation -- preferred stocks, exchange-traded funds that invest primarily in preferred stocks, and corporate bonds and other debt securities with preferred characteristics -- outperformed the value-oriented Index during a period when value stocks generally underperformed the broader U.S. equity market.

Past performance is no guarantee of future results. Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s Dividend Reinvestment Plan. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. Performance at market price will differ from performance at NAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return.

The preferred allocation also outperformed the overall preferred market, as measured by the ICE BofA Fixed Rate Preferred Securities Index. Outperformance was driven largely by an overweight position in the energy sector, with strong returns coming from natural gas distributors. Exposures to electric utilities and insurance companies also contributed to the preferred allocation’s performance during the period.

Fund Distributions

Pursuant to an exemptive order issued by the Securities and Exchange Commission (the Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders. The Fund’s MDP had no effect on the Fund’s investment strategy during the most recent fiscal year and is not expected to have an effect in future periods, but distributions in excess of Fund returns will cause its per share NAV to erode. Investors should not draw any conclusions about the Fund’s investment performance from the amount of its distribution or from the terms of its MDP.

For the period from November 1, 2022 to October 31, 2023, the Fund made monthly distributions of $0.1488 per share. The Fund’s distributions may be comprised of amounts characterized for federal income tax purposes as qualified and non-qualified ordinary dividends, capital gains and non-dividend distributions, also known as return of capital distributions. The federal income tax character of distributions is determined after the end of the calendar year and reported to shareholders on the Internal Revenue Service’s form 1099-DIV. For additional information, see Note 2 in the Notes to Financial Statements herein.

Tax-Advantaged Dividend Income Fund

The Fund's Investment Objectives, Principal Strategies and Principal Risks

‡

---

Investment Objectives. 

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.

Principal Strategies. 

Under normal market conditions, the Fund invests at least 80% of its total managed assets in dividend-paying common and preferred stocks that Eaton Vance believes at the time of investment are eligible to pay dividends that qualify for federal income taxation at rates applicable to long-term capital gains (‘‘tax-advantaged dividends’’). For the purposes of the 80% test, total assets is defined as net assets plus any borrowings for investment purposes. The Fund may invest in common and preferred stocks of both domestic and foreign issuers. Preferred stocks may include other hybrid securities. The Fund can invest up to 10% of its net assets in exchange-traded funds (“ETFs”) that invest primarily in preferred stocks. The Fund may also lend its securities. The Fund may invest in preferred stocks of any grade quality. The Fund may invest up to 30% of its total managed assets in securities rated below investment grade quality (which is lower than BBB– as determined by S&P Global Ratings (‘‘S&P’’) or Fitch Ratings (‘‘Fitch’’), Baa3 as determined by Moody’s Investors Service, Inc. (‘‘Moody’s’’) or, if unrated, determined to be of comparable quality by Eaton Vance). Securities of below investment grade quality commonly are referred to as ‘‘junk’’ preferred stocks and bonds, as the case may be.

In addition to investing in stocks that pay tax-advantaged dividends, the Fund may also invest a portion of its assets in stocks and other securities (including preferred stocks, hybrid securities, or bonds) that generate fully taxable ordinary income (i.e., income other than tax-advantaged dividends).

In seeking its objective, the Fund may engage in dividend capture trading. The Fund may use derivatives principally to seek to manage exposure to certain sectors and/or markets in connection with its use of dividend capture trading. The Fund expects to buy and sell equity index futures contracts for this purpose, but may also engage in other types of derivatives to manage such exposures. Additionally, the Fund may also use derivatives for other purposes, such as hedging, to enhance return or as a substitute for the purchase or sale of securities or currencies. Other permitted derivatives include futures contracts on securities and non-equity indices, options on futures contracts, the purchase of put options and the sale of call options on securities held, equity swaps, interest rate swaps, covered short sales, forward sales of stocks, forward currency exchange contracts and currency futures contracts. The Fund may invest in the foregoing derivatives without limitation and use of derivatives may be extensive. The Fund may also invest in credit derivatives (credit default swaps, total return swaps, credit options and other derivative transactions with substantially similar characteristics and risks), provided that the notional value of such derivative instruments entered into for non-hedging purposes does not exceed 5% of the value of preferred stocks held by the Fund.

The Fund may invest a significant portion of its assets in securities of issuers in any single industry or sector of the economy if companies in that industry or sector meet the Fund’s investment criteria. The Fund may not invest 25% or more of its total managed assets in the securities of issuers in any single industry. The Fund may invest a significant portfolio of its assets in the financial services sector.

During unusual market conditions, the Fund may invest up to 100% of its assets in cash or cash equivalents temporarily, which may be inconsistent with its investment objectives, principal strategies and other policies.

The Fund employs leverage through borrowings to seek opportunities for additional income. Leverage may amplify the Fund’s net asset value of any increase or decrease in the value of investments held. There can be no assurance that the use of borrowings will be successful.

Principal Risks

Market Discount Risk.

As with any security, the market value of the common shares may increase or decrease from the amount initially paid for the common shares. The Fund’s common shares have traded both at a premium and at a discount relative to NAV. The shares of closed-end management investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the Fund’s NAV may decrease.

Market Risk.

The value of investments held by the Fund may increase or decrease in response to social, economic, political, financial, public health crises or other disruptive events (whether real, expected or perceived) in the U.S. and global markets, and include events such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest. These events may negatively impact broad segments of businesses and populations and may exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund’s investments cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in reaction to changing market conditions. Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility. No active trading market may exist for certain investments held by the Fund, which may impair the ability of the Fund to sell or to realize the current valuation of such investments in the event of the need to liquidate such assets.

Issuer Risk

. The value of common and preferred stocks may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Equity Securities Risk.

The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer and sector-specific considerations; unexpected trading activity among retail investors; or other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund’s equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous levels.

Tax-Sensitive Investing Risk.

The Fund may hold a security in order to achieve more favorable tax-treatment or to sell a security in order to create tax losses. The Fund’s utilization of various tax-management techniques may be curtailed or eliminated by tax legislation, regulation or interpretations. The Fund may not be able to minimize taxable distributions to shareholders and a portion of the Fund’s distributions may be taxable.

Tax Risk.

Although the Fund seeks to minimize and defer the federal income taxes incurred by common shareholders in connection with their investment in the Fund, there can be no assurance that it will be successful in this regard. The tax treatment and characterization of the Fund’s distributions may change over time due to changes in the Fund’s mix of investment returns and changes in the federal tax laws, regulations and administrative and judicial interpretations. The Fund’s investment program and the tax treatment of Fund distributions may be affected by IRS interpretations of the Internal Revenue Code of 1986, as amended (the “Code”) and future changes in tax laws and regulations. Distributions paid on the common shares may be characterized variously as non-qualified dividends (taxable at ordinary income rates), qualified dividends (generally taxable at long-term capital gains rates), capital gains dividends (taxable at long-term capital gains rates) or return of capital (generally not currently taxable). The ultimate tax characterization of the Fund’s distributions made in a calendar year may not finally be determined until after the end of that calendar year. Distributions to a common shareholder that are return of capital are tax free to the amount of the common shareholder’s current tax basis in his or her common shares, with any distribution amounts exceeding such basis treated as capital gain on a deemed sale of common shares. common shareholders are required to reduce their tax basis in common shares by the amount of tax-free return of capital distributions received, thereby increasing the amount of capital gain (or decreasing the amount of capital loss) to be recognized upon a later disposition of the common shares. In order for Fund distributions of qualified dividend income to be taxable at favorable long-term capital gains rates, a common shareholder must meet certain prescribed holding period and other requirements with respect to his or her common shares. If positions held by the Fund were treated as “straddles” for federal income tax purposes, dividends on such positions would not constitute qualified dividend income subject to favorable income tax treatment.

Currency Risk.

Exchange rates for currencies fluctuate daily. The value of foreign investments may be affected favorably or unfavorably by changes in currency exchange rates in relation to the U.S. dollar. Currency markets generally are not as regulated as securities markets and currency transactions are subject to settlement, custodial and other operational risks.

Foreign Currency Transactions Risk

. The value of foreign assets as measured in U.S. dollars may be affected favorably or unfavorably by changes in foreign currency rates and exchange control regulations. Currency exchange rates can also be affected unpredictably by intervention by U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments in the U.S. or abroad. Foreign currency exchange transactions may be conducted on a spot (i.e., cash) basis at the spot rate prevailing in the foreign currency exchange market or through entering into derivative currency transactions. Currency futures contracts are exchange-traded and change in value to reflect movements of a currency or a basket of currencies. Settlement must be made in a designated currency.

Forward foreign currency exchange contracts are individually negotiated and privately traded so they are dependent upon the creditworthiness of the counterparty. Such contracts may be used when a security denominated in a foreign currency is purchased or sold, or when the receipt in a foreign currency of dividend or interest payments on such a security is anticipated. A forward contract can then ‘‘lock in’’ the U.S. dollar price of the security or the U.S. dollar equivalent of such dividend or interest payment, as the case may be. Additionally, when the Adviser believes that the currency of a particular foreign country may suffer a substantial decline against the U.S. dollar, it may enter into a forward contract to sell, for a fixed amount of dollars, the amount of foreign currency approximating the value of some or all of the securities held that are denominated in such foreign currency. The precise matching of the forward contract amounts and the value of the securities involved will not generally be possible. In addition, it may not be possible to hedge against long-term currency changes. Cross-hedging may be performed by using forward contracts in one currency (or basket of currencies) to hedge against fluctuations in the value of securities denominated in a different currency if the Adviser determines that there is an established historical pattern of correlation between the two currencies (or the basket of currencies and the underlying currency). Use of a different foreign currency magnifies exposure to foreign currency exchange rate fluctuations. Forward contracts may also be used to shift exposure to foreign currency exchange rate changes from one currency to another. Short-term hedging provides a means of fixing the dollar value of only a portion of portfolio assets.

Currency transactions are subject to the risk of a number of complex political and economic factors applicable to the countries issuing the underlying currencies. Furthermore, unlike trading in most other types of instruments, there is no systematic reporting of last sale information with respect to the foreign currencies underlying the derivative currency transactions. As a result, available information may not be complete. In an over-the-counter trading environment, there are no daily price fluctuation limits. There may be no liquid secondary market to close out options purchased or written, or forward contracts entered into, until their exercise, expiration or maturity. There is also the risk of default by, or the bankruptcy of, the financial institution serving as a counterparty.

Sector Risk.

Because the Fund may, under certain market conditions, invest a significant portion of its assets in the utilities and/or financial services sectors, the value of Fund shares may be affected by events that adversely affect those sectors and may fluctuate more than that of a more broadly diversified fund. The industries within the financial services sector are subject to extensive government regulation, which can limit both the amounts and types of loans and other financial commitments they can make, and the interest rates and fees they can charge. Profitability can be largely dependent on the availability and cost of capital funds and the rate of corporate and consumer debt defaults, and can fluctuate significantly when interest rates change. Credit losses resulting from financial difficulties of borrowers can negatively affect the financial services industries. Insurance companies can be subject to severe price competition. The financial services industries are currently undergoing relatively rapid change as existing distinctions between financial service segments become less clear. For example, recent business combinations have included insurance, finance, and securities brokerage under single ownership. Some primarily retail corporations have expanded into securities and insurance industries.

The Fund's Investment Objectives, Principal Strategies and Principal Risks

‡

 — continued

---

Preferred Stock Risk.

Although preferred stocks represent an ownership interest in an issuer, preferred stocks generally do not have voting rights or have limited voting rights and have economic characteristics similar to fixed-income securities. Preferred stocks are subject to issuer-specific risks generally applicable to equity securities and credit and interest rate risks generally applicable to fixed-income securities. The value of preferred stock generally declines when interest rates rise and may react more significantly than bonds and other debt instruments to actual or perceived changes in the company’s financial condition or prospects.

Hybrid Securities Risk

. Hybrid securities generally possess characteristics common to both equity and debt securities. Preferred stocks, convertible securities, and certain debt obligations are types of hybrid securities. Hybrid securities generally have a preference over common stock in the event of the issuer’s liquidation and perpetual or near perpetual terms at time of issuance. Hybrid securities generally do not have voting rights or have limited voting rights. Because hybrid securities have both debt and equity characteristics, their values vary in response to many factors, including general market and economic conditions, issuer-specific events, changes in interest rates, credit spreads and the credit quality of the issuer, and, for convertible securities, factors affecting the securities into which they convert.

Contingent Convertible Securities

. Contingent convertible securities (sometimes referred to as “CoCos”) are convertible securities with loss absorption characteristics. These securities provide for mandatory conversion into common stock of the issuer under certain circumstances. The mandatory conversion may be automatically triggered, for instance, if a company fails to meet the capital minimum with respect to the security, the company’s regulator makes a determination that the security should convert or the company receives specified levels of extraordinary public support. Since the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero; and conversion would deepen the subordination of the investor, hence worsening standing in a bankruptcy. In addition, some such instruments have a set stock conversion rate that would cause an automatic write-down of capital if the price of the stock is below the conversion price on the conversion date. Under similar circumstances, the liquidation value of certain types of contingent convertible securities may be adjusted downward to below the original par value. The write down of the par value would occur automatically and would not entitle the holders to seek bankruptcy of the company. In certain circumstances, contingent convertible securities may write down to zero and investors could lose the entire value of the investment, even as the issuer remains in business. CoCos may be subject to redemption at the option of the issuer at a predetermined price.

Value Investing Risk

. The Fund focuses its investments on dividend-paying common and preferred stocks that the Adviser believes are undervalued or inexpensive relative to other investments. These types of securities may present risks in addition to the general risks associated with investing in common and preferred stocks. These securities generally are selected on the basis of an issuer’s fundamentals relative to current market price. Such securities are subject to the risk of misestimation of certain fundamental factors. In addition, during certain time periods, market dynamics may favor ‘‘growth’’ stocks over ‘‘value’’ stocks. Disciplined adherence to a ‘‘value’’ investment mandate during such periods can result in significant underperformance relative to overall market indices and other managed investment vehicles that pursue growth style investments and/or flexible equity style mandates.

Income Risk.

The Fund’s ability to distribute income to shareholders will depend on the yield available on the common and preferred stocks and other hybrid securities and fixed-income securities held by the Fund. Changes in the dividend policies of companies held by the Fund could make it difficult for the Fund to provide a predictable level of income.

Dividend Capture Trading Risk.

The use of dividend capture strategies will expose the Fund to higher portfolio turnover, increased trading costs and potential for capital loss or gain, particularly in the event of significant short-term price movements of stocks subject to dividend capture trading.

Credit Risk.

Investments in fixed income and other debt obligations, including loans, (referred to below as “debt instruments”) are subject to the risk of non-payment of scheduled principal and interest. Changes in economic conditions or other circumstances may reduce the capacity of the party obligated to make principal and interest payments on such instruments and may lead to defaults. Such non-payments and defaults may reduce the value of Fund shares and income distributions. The value of debt instruments also may decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings of debt instruments may be lowered if the financial condition of the party obligated to make payments with respect to such instruments deteriorates. In the event of bankruptcy of the issuer of a debt instrument, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing the instrument. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel, which may increase the Fund’s operating expenses and adversely affect net asset value.

Below Investment Grade Securities Risk

. The Fund’s investments in preferred stocks and bonds of below investment grade quality, if any, are predominantly speculative because of the credit risk of their issuers. While offering a greater potential opportunity for capital appreciation and higher yields, preferred stocks and bonds of below investment grade quality entail greater potential price volatility and may be less liquid than higher-rated securities. Issuers of below investment grade quality preferred stocks and bonds are more likely to default on their payments of dividends/interest and liquidation value/principal owed to the Fund, and such defaults will reduce the Fund’s net asset value and income distributions. The prices of these lower quality preferred stocks and bonds are more sensitive to negative developments than higher rated securities. Adverse business conditions, such as a decline in the issuer’s revenues or an economic downturn, generally lead to a higher non-payment rate. In addition, such a security may lose significant value before a default occurs as the market adjusts to expected higher non-payment rates.

The registrant undertakes to provide a copy of such code of ethics to any person upon request, without charge, by calling 1-800-262-1122. The registrant has not amended the code of ethics as described in Form N-CSR during the period covered by this report. The registrant has not granted any waiver, including an implicit waiver, from a provision of the code of ethics as described in Form N-CSR during the period covered by this report.

Item 4. Principal Accountant Fees and Services

(a)-(d)

The following table presents the aggregate fees billed to the registrant for the registrant’s fiscal years ended October 31, 2022 and October 31, 2023 by the registrant’s principal accountant, Deloitte & Touche LLP (“D&T”), for professional services rendered for the audit of the registrant’s annual financial statements and fees billed for other services rendered by D&T during such periods.

(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) The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed for services rendered to the registrant by D&T for the registrant’s fiscal years ended October 31, 2022 and October 31, 2023; and (ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed for services rendered to the Eaton Vance organization by D&T for the same time periods.

(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.

(i) Not applicable.

(j) Not applicable.

Gorman, Keith Quinton, Scott E. Wennerholm (Chair), and Nancy A. Wiser 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 the Fund 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 Policies annually. 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, or any committee, sub-committee or group of independent trustees identified by the Board, which will instruct the investment adviser on the appropriate course of action. If the Board Members are unable to meet and the failure to vote a proxy would have a material adverse impact on the Fund, the investment adviser may vote such proxy, provided that it discloses the existence of the material conflict to the Chairperson of the Fund’s Board as soon as practicable and to the Board at its next meeting.

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. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies in accordance with customized proxy voting guidelines (the “Guidelines”) and/or refer them back to the investment adviser pursuant to the Policies.

The Agent is required to establish and maintain adequate internal controls and policies in connection with the provision of proxy voting services, including methods to reasonably ensure that its analysis and recommendations are not influenced by a conflict of interest. The Guidelines include 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 cause the Fund to abstain from voting from time to time where it determines that the costs associated with voting a proxy outweigh the benefits derived from exercising the right to vote or it is unable to access or access timely ballots or other proxy information, among other stated reasons. The Agent will refer Fund proxies to the investment adviser for instructions under circumstances where, among others: (1) the application of the Guidelines is unclear; (2) a particular proxy question is not covered by the Guidelines; or (3) the Guidelines require input from the investment adviser. When a proxy voting issue has been referred to the investment adviser, the analyst (or portfolio manager if applicable) covering the company subject to the proxy proposal determines the final vote (or decision not to vote) and the investment adviser’s Proxy Administrator (described below) instructs the Agent to vote accordingly for securities held by the Fund. Where more than one analyst covers a particular company and the recommendations of such analysts voting a proposal conflict, the investment adviser’s Global Proxy Group (described below) will review such recommendations and any other available information related to the proposal and determine the manner in which it should be voted, which may result in different recommendations for the Fund that may differ from other clients of the investment adviser.

The investment adviser has appointed a Proxy Administrator to assist in the coordination of the voting of client proxies (including the Fund’s) in accordance with the Guidelines and the Policies. The investment adviser and its affiliates have also established a Global Proxy Group. The Global Proxy Group develops the investment adviser’s positions on all major corporate issues, creates the Guidelines and oversees the proxy voting process. The Proxy Administrator maintains a record of all proxy questions that have been referred by the Agent, all applicable recommendations, analysis and research received and any resolution of the matter. Before instructing the Agent to vote contrary to the Guidelines or the recommendation of the Agent, the Proxy Administrator will provide the Global Proxy Group with the Agent’s recommendation for the proposal along with any other relevant materials, including the basis for the analyst’s recommendation. The Proxy Administrator will then instruct the Agent to vote the proxy in the manner determined by the Global Proxy Group. A similar process will be followed if the Agent has a conflict of interest with respect to a proxy. The investment adviser will report to the Fund’s Board any votes cast contrary to the Guidelines or Agent recommendations, as applicable, no less than annually.

The investment adviser’s Global Proxy Group is responsible for monitoring and resolving possible material conflicts with respect to proxy voting. Because the Guidelines are predetermined and designed to be in the best interests of shareholders, application of the Guidelines to vote client proxies should, in most cases, adequately address any possible conflict of interest. The investment adviser will monitor situations that may result in a conflict of interest between any of its clients and the investment adviser or any of its affiliates by maintaining a list of significant existing and prospective corporate clients. The Proxy Administrator will compare such list with the names of companies of which he or she has been referred a proxy statement (the “Proxy Companies”). If a company on the list is also a Proxy Company, the Proxy Administrator will report that fact to the Global Proxy Group. If the Proxy Administrator intends to instruct the Agent to vote in a manner inconsistent with the Guidelines, the Global Proxy Group will first determine, in consultation with legal counsel if necessary,

whether a material conflict exists. If it is determined that a material conflict exists, the investment adviser will seek instruction on how the proxy should be voted from the Fund’s Board, or any committee or subcommittee identified by the Board. If a matter is referred to the Global Proxy Group, the decision made and basis for the decision will be documented by the Proxy Administrator and/or Global Proxy Group.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is 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. Portfolio Managers of Closed-End Management Investment Companies

Eaton Vance Management (“EVM” or “Eaton Vance”) is the investment adviser of the Fund. Derek J.V. DiGregorio, Aaron S. Dunn, Bradley T. Galko and Joseph Mehlman, CFA comprise the investment team responsible for the overall management of the Fund’s investments.

Mr. DiGregorio is a Vice President of EVM and has been a portfolio manager of the Fund since July 2021. Mr. Dunn is a Vice President of EVM, is a member of EVM’s Equity Strategy Committee and has been a portfolio manager of the Fund since December 2017. Mr. Galko is a Vice President of EVM, has been an equity analyst at EVM since 2013 and has been a portfolio manager of the Fund since February 2020. Mr. Mehlman is a Vice President of EVM and a Managing Director at Morgan Stanley Investment Management Inc., an affiliate of EVM. Mr. Mehlman has been employed by the Morgan Stanley organization for more than five years and has been a portfolio manager of the Fund since November 2022. Messrs. DiGregorio, Dunn and Galko have been employed by EVM for more than five years. This information is provided as of the date of filing this report.

The following table shows, as of the Fund’s most recent fiscal year end, the number of accounts each portfolio manager managed in each of the listed categories and the total assets (in millions of dollars) in the accounts managed within each category. The table also shows the number of accounts with respect to which the advisory fee is based on the performance of the account, if any, and the total assets (in millions of dollars) in those accounts.

The following table shows the dollar range of Fund shares beneficially owned by each portfolio manager as of the Fund’s most recent fiscal year end.

Potential for Conflicts of Interest. It is possible that conflicts of interest may arise in connection with a portfolio manager’s management of the Fund’s investments on the one hand and the investments of other accounts for which a portfolio manager is responsible on the other. For example, a portfolio manager may have conflicts of interest in allocating management time, resources and investment opportunities among the Fund and other accounts he advises. In addition, due to differences in the investment strategies or restrictions between the Fund and the other accounts, the portfolio manager may take action with respect to another account that differs from the action taken with respect to the Fund. In some cases, another account managed by a portfolio manager may compensate the investment adviser based on the performance of the securities held by that account. The existence of such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise his discretion in a manner that he believes is equitable to all interested persons. EVM has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

Compensation Structure for EVM

The compensation structure of Eaton Vance and its affiliates that are investment advisers (for purposes of this section “Eaton Vance”) is based on a total reward system of base salary and incentive compensation, which is paid either in the form of cash bonus, or for employees meeting the specified deferred compensation eligibility threshold, partially as a cash bonus and partially as mandatory deferred compensation. Deferred compensation granted to Eaton Vance employees is generally granted as a mix of deferred cash awards under the Investment Management Alignment Plan (IMAP) and equity-based awards in the form of stock units. The portion of incentive compensation granted in the form of a deferred compensation award and the terms of such awards are determined annually by the Compensation, Management Development and Succession Committee of Morgan Stanley.

Base salary compensation. Generally, portfolio managers receive base salary compensation based on the level of their position with the adviser.

Incentive compensation. In addition to base compensation, portfolio managers may receive discretionary year-end compensation. Incentive compensation may include:

Eaton Vance compensates employees based on principles of pay-for-performance, market competitiveness and risk management. Eligibility for, and the amount of any, discretionary compensation is subject to a multi-dimensional process. Specifically, consideration is given to one or more of the following factors, which can vary by portfolio management team and circumstances:

Further, the firm’s Global Incentive Compensation Discretion Policy requires compensation managers to consider Further the only legitimate, business related factors when exercising discretion in determining variable incentive compensation, including adherence to Morgan Stanley’s core values, conduct, disciplinary actions in the current performance year, risk management and risk outcomes.

Eaton Vance Tax-Advantaged Dividend Income Fund

Form N-CSR Item 13(c) Exhibit

Dear Eaton Vance Fund Shareholder:

This notice provides shareholders of the Eaton Vance Tax-Advantaged Dividend Income Fund (NYSE: EVT) with important information concerning the distribution declared in May 2023. You are receiving this notice as a requirement of the Fund’s managed distribution plan (Plan). The Board of Trustees approved the implementation of the Plan to make monthly cash distributions to common shareholders, stated in terms of a fixed amount per common share. This information is sent to you for informational purposes only and is an estimate of the sources of the May distribution. It is not determinative of the tax character of the Fund’s distributions for the 2023 calendar year.

The amounts and sources of distributions reported in this notice are estimates, are not being provided for tax reporting purposes and the distribution may later be determined to be from other sources including realized short-term gains, long-term gains, to the extent permitted by law, and return of capital. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Distribution Period: May 2023

Distribution Amount per Common Share: $0.1488

The following table sets forth an estimate of the sources of the Fund’s May distribution and its cumulative distributions paid this fiscal year to date. Amounts are expressed on a per common share basis and as a percentage of the distribution amount.

Eaton Vance Tax-Advantaged Dividend Income Fund

IMPORTANT DISCLOSURE: You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s Plan. The Fund estimates that it has distributed more than its income and net realized capital gains; therefore, a portion of your distribution may be a return of capital. A return of capital may occur for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with ‘yield’ or ‘income.’ The amounts and sources of distributions reported in this Notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for accounting and/or tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Set forth in the table below is information relating to the Fund’s performance based on its net asset value (NAV) for certain periods.
