CEO corner

To Our Shareholders,

The stock market gained ground in the first half of 2007, returning 6.96% through June 30, as measured by the Standard & Poor’s 500 Index. It was bolstered by stronger-than-expected corporate earnings growth, healthy global economic growth, increased merger and acquisitions activity and mostly steady interest rates. These positives served to overcome concerns about inflation, a slumping housing market, the subprime mortgage debacle and mixed signals on the future direction of interest rates.

In fact, at the end of May, the stock market passed a significant milestone, when the broad Standard & Poor’s 500 Index climbed beyond the record it had set seven years ago. From its peak in March 2000, the stock market spiraled downward three consecutive years, bottoming in 2002. The upturn began in 2003, and the market has advanced each year since, finally setting a new high on May 30, 2007.

This nearly complete market cycle highlights the importance of an investment principle you have heard us speak of often: diversification. That is because it is a key to protecting, and growing, your assets. By allocating your investments among different asset classes, investment styles and portfolio managers, you are likely to be well represented through all phases of a complete market cycle, with the winners helping to cushion the fall of the losers.

The challenge for investors with a diversified portfolio is to properly evaluate your investments to tell the difference between an underperforming manager and an out-of-favor style, while also understanding the role each investment plays in your portfolio. That’s where your financial professional can provide true value. He or she can help you make those assessments and also counsel patience, because a properly diversified portfolio by its very nature will typically have something lagging or out of favor — a concept that can be difficult to live with, but necessary to embrace. If everything in your portfolio is “working,” then you are not truly diversified, but rather are leveraged to the current market and the flavor of the day. If so, you are bound to be out of step in the near future.

With the recent volatility in the securities markets, it has prompted investors to question how long this type of market cycle will last. History tells us it will end and that when it does, today’s leaders may well turn into laggards and vice versa. Indeed, the current subprime mortgage market woes, the subsequent credit crunch and their impact on the financial markets and the global credit markets, are just the latest examples of why investors should be well-diversified. For with patience and a diversified portfolio, it could be easier to weather the market’s twists and turns and reach your long-term goals.

Sincerely,


Keith F. Hartstein,
President and Chief Executive Officer

Your fund at a glance

The Fund seeks to provide a high level of after-tax total return from dividend income and capital appreciation. To meet its objectives, the Fund normally invests at least 80% of its assets in dividend-paying common and preferred securities that the Adviser believes are eligible to pay dividends that qualify for U.S. taxation rates applicable to long-term capital gains, which currently are taxed at a maximum rate of 15%.

Over the last six months

Preferred and utility common stocks struggled during the period, hurt by interest rate concerns.

Utility common stock holdings aided the Fund's returns the most.

Tax-advantaged preferred holdings performed well, but those without tax benefits come under pressure.

Managers’ report

John Hancock

Tax-Advantaged

Dividend Income Fund

Owing largely to a late-period sell-off, utility common stocks and preferred stocks — two primary areas of emphasis for John Hancock Tax-Advantaged Dividend Income Fund — struggled during the six-month period ended June 30, 2007. Throughout much of the first four months of 2007, both segments continued to be bolstered by persistently strong investor demand for securities that generated attractive levels of incremental income over U.S. Treasury securities. A reasonably benign interest rate environment also helped as the Federal Reserve Board left its target short-term interest rate unchanged at 5.25% .

In late February and early March, a plunge in Chinese stocks that sparked worldwide equity market declines, along with growing worries about problems in the subprime mortgage market, prompted investors to seek out the relative safety of high-quality, income-producing investments. A spate of merger and acquisition activity also helped utility stocks in late winter, although preferreds struggled during that time as a growing supply of the securities acted as a drag on their prices. Then in May and June, preferred stocks and utility common stocks came under significant pressure amid a bout of profit-taking, as investors seemingly concluded that the Fed wasn’t going to be cutting rates in 2007.

Financial stocks — another area of emphasis for the Fund — performed poorly. In the early months of the period, they more or less tread water as investors waited in vain for a cut in U.S. interest rates, which would help to improve the profit margins of many financial companies. Growing concerns about just how much pain the meltdown in the subprime mortgage market was causing banks, investment firms and hedge funds also weighed on financials.

“Owing largely to a late-period

sell-off, utility common stocks

and preferred stocks … struggled

during the six-month period

ended June 30, 2007.”

Performance

For the six months ended June 30, 2007, John Hancock Tax-Advantaged Dividend Income Fund returned 0.33% at net asset value (NAV) and –1.16% at market value. The difference in the Fund’s NAV performance and its market performance stems from the fact that the market share price is subject to the dynamics of secondary market trading, which could cause it to trade at a discount or premium to the Fund’s NAV share price at any time. The Fund’s yield at closing market price on June 30, 2007 was 5.94% . By comparison, the average closed-end specialty-utilities fund returned 5.10% at net asset value, according to Morningstar, Inc. For the same six-month period, the Merrill Lynch Preferred Stock DRD Index rose 0.56%, the S&P 400 Mid-Cap Utilities Index returned 2.66% and the S&P 500 Bank Index returned –3.33% .

Utility commons lead

As they have for some time now, our utility common stock holdings provided the biggest boost to the Fund’s performance. Among the most significant contributors was National Fuel Gas Co. It performed well, thanks in large part to strong pricing conditions for natural gas and investors’ excitement over the company’s plans to explore for gas in the

Devonian black shales region in Pennsylvania and New York. Our holdings in Energy East Corp. were also among our biggest winners, as the company was the target of a cash buyout offer in June by a Spanish utility. Our stake in Dominion Resources, Inc. also performed well, bolstered in part by the company’s sale of most of its oil and gas properties, as well as its intended buyback of a large dollar amount of its outstanding common stock. Telecommunications giants AT&T, Inc., Verizon Communications, Inc. and Vodafone Group Plc all posted good gains due to growing recognition that the stocks provided an attractive dividend yield and were operating in one of the fastest-growing industries around the world. The rising price of oil also helped our energy-related holdings, specifically BP Plc, Chevron Corp. and Total SA.

Among our preferred holdings, we enjoyed a strong performance from PNM Resources, Inc., helped by the company’s ability to generate greater-than-expected customer growth. In addition, investors were excited by news that Microsoft founder Bill Gates’ personal investment vehicle was entering into a joint venture with the utility and energy company. Our holdings in MetLife, Inc. also served us well, aided by strong demand for DRD-eligible preferreds. Bank of America Corp.’s preferred holdings also enjoyed solid performance, helped by investor demand for attractively priced tax-advantaged preferred stocks issued by high-quality companies amid a dearth of such securities.

Financials lag

In terms of laggards, financial stocks as a whole detracted most from our performance. Banks such as Wachovia Corp. performed poorly, as investors worried about the direction of interest rates and the housing slowdown’s impact on a host of financial companies.

We lost ground with our stake in the preferred stock of student-loan company SLM Corp. Investors became concerned about a potential credit downgrade of the company amid news about the financing details of the company’s agreement to be taken private in a leveraged buyout. Of particular concern was the high level of debt that would have to be serviced through cash flow from operations. We continued to hold on to SLM because

we believe the stock’s price reflected the worst-case scenario, and we weren’t willing to part with it at such discounted valuations.

“As they have for some time now,

our utility common stock holdings

provided the biggest boost to the

Fund’s performance.”

Outlook

As we enter the second half of 2007, we’re cautiously optimistic about the prospects for preferred and utility common stocks. In our view, the ongoing downturn in the housing market and the higher consumer interest rates and bond yields that we saw at the end of the period could have a slowing effect on the economy in coming months. If economic growth trails off and inflation remains in check, we could see a rally in Treasury bonds. That rally, in turn, would likely be the catalyst for better performance for preferred and utility common stocks, but especially bank common stocks.

Notes to financial statements (unaudited)

Note 1
Accounting policies

John Hancock Tax-Advantaged Dividend Income Fund (the Fund) is a closed-end diversified management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act).

Significant accounting policies of the Fund
are as follows:

Security valuation

The net asset value of the common shares of the Fund is determined daily as of the close of the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. Short-term debt investments that have a remaining maturity of 60 days or less are valued at amortized cost, and thereafter assume a constant amortization to maturity of any discount or premium, which approximates market value. Investments in John Hancock Cash Investment Trust, an affiliate of John Hancock Advisers, LLC (the Adviser), a wholly owned subsidiary of John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (MFC), are valued at their net asset value each business day. All other securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade or, lacking any sales, at the closing bid price. Securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Securities for which there are no such quotations, principally debt securities, are valued based on the valuation provided by an independent pricing service, which utilizes both dealer-supplied and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate,  maturity, type of issue, trading characteristics and other market data.

Other assets and securities for which no such quotations are readily available are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of trading on the NYSE. The values of such securities used in computing the net asset value of the Fund’s shares are generally determined as of such times. Occasionally, significant events that affect the values of such securities may occur between the times at which such values are generally determined and the close of the NYSE. Upon such an occurrence, these securities will be valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

Investment transactions

Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Net realized gains and losses on sales of investments are determined on the identified cost basis.

Expenses

The majority of expenses are directly identifiable to an individual fund. Expenses that are not readily identifiable to a specific fund are allocated in such a manner as deemed equitable, taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures tends to increase the Fund’s exposure to the underlying instrument.

Tax-Advantaged Dividend Income Fund

16


Selling futures tends to decrease the Fund’s exposure to the underlying instrument or hedge other Fund instruments. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities or cash as collateral for the account of the broker (the Fund’s agent in acquiring the futures position). Each day, the futures contract is valued at the official settlement price of the board of trade or U.S. commodities exchange on which it trades. Subsequent payments to and from the broker, known as “variation margin,” are made on a daily basis as the market price of the financial futures contract fluctuates. Daily variation margin adjustments arising from this “mark to market” are recorded by the Fund as unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks of entering into financial futures contracts include the possibility that there may be an illiquid market and/or that a change in the value of the contracts may not correlate with changes in the value of the underlying securities. In addition, the Fund could be prevented from opening or realizing the benefits of closing out financial futures positions because of position limits or limits on daily price fluctuation imposed by an exchange.

For federal income tax purposes, the amount, character and timing of the Fund’s gains and/or losses can be affected as a result of financial futures contracts. On June 30, 2007, the Fund had deposited $189,000 in a segregated account for the broker to cover margin requirements on open financial futures contracts.

The Fund had the following financial futures contracts open on June 30, 2007:   
  NUMBER OF       
OPEN CONTRACTS  CONTRACTS  POSITION  EXPIRATION  APPRECIATION 

U.S. Treasury 10-Year Note  120  Short  Sep 2007  $241,972 
U.S. Treasury 10-Year Note  150  Short  Sep 2007  302,464 
        $544,436 

Federal income taxes

The Fund qualifies as a “regulated investment company” by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

New accounting pronouncements

In June 2006, Financial Accounting Standards Board (FASB) Interpretation No. 48,  Accounting for Uncertainty in Income Taxes (the Interpretation), was issued and is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the effective date. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management has evaluated the application of this Interpretation to the Fund and does not believe there is a material impact resulting from the adoption of this Interpretation on the Fund’s financial statements.

In September 2006, FASB Standard No. 157,  Fair Value Measurements (FAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishing a framework for measuring fair value, and expands disclosure about fair value measurements. Management is currently evaluating the application of FAS 157 to the Fund and its impact, if any, resulting from the adoption of FAS 157 on the Fund’s financial statements.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend date or, in the case of some foreign securities, on the date thereafter when the Fund identifies the dividend. Interest income on investment securities is recorded on the accrual basis. Foreign income may be subject to foreign withholding taxes, which are accrued as applicable.

Tax-Advantaged Dividend Income Fund

17


The Fund records distributions to shareholders from net investment income and net realized gains, if any, on the ex-dividend date. During the year ended December 31, 2006, the tax character of distributions paid was as follows: ordinary income $69,051,314 and long-term capital gain $18,618,635. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time and are in the same amount, except for the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Distributions in excess of tax basis earnings and profits, if any, are reported in the Fund’s financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with accounting principles generally accepted in the United States of America, incorporates estimates made by management in determining the reported amount of assets, liabilities, revenues and expenses of the Fund. Actual results could differ from these estimates.

Note 2
Management fee and transactions with
affiliates and others

The Fund has an investment management contract with the Adviser. Under the investment management contract, the Fund pays a daily management fee to the Adviser at an annual rate of 0.75% of the Fund’s average daily net asset value.

The Adviser has contractually agreed to limit the Fund’s management fee to the following: 0.55% of the Fund’s average daily managed assets until the fifth anniversary of the commencement of the Fund’s operations, 0.60% of such assets in the sixth year, 0.65% of such assets in the seventh year and 0.70% of average daily managed assets in the eighth year. Accordingly, the expense reductions related to the reduction in the management fee amounted to $1,339,011 for the period ended June 30, 2007.  After the eighth year, the Adviser will no longer waive a portion of the management fee.

The Fund has an agreement with the Adviser and affiliates to perform necessary tax, accounting and legal services for the Fund. The compensation for the period amounted to $76,068. The Fund also reimbursed John Hancock Life Insurance Company (JHLICO), a subsidiary of MFC, for certain compliance costs, included in the Fund’s Statement of Operations.

The Adviser and other subsidiaries of JHLICO owned 7,487 shares of beneficial interest of the Fund on June 30, 2007.

Mr. James R. Boyle is Chairman of the Adviser, as well as affiliated Trustee of the Fund, and is compensated by the Adviser and/or its affiliates. The compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for tax purposes, their receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments into other John Hancock funds, as applicable, to cover its liability for the deferred compensation. Investments to cover the Fund’s deferred compensation liability are recorded on the Fund’s books as an other asset. The deferred compensation liability and the related other asset are always equal and are marked to market on a periodic basis to reflect any income earned by the investments, as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

The Fund is listed for trading on the NYSE and has filed with the NYSE its chief executive officer certification regarding compliance with the NYSE’s listing standards. The Fund also files with the Securities and Exchange Commission (the SEC) the certification of its chief executive officer and chief financial officer required by Section 302 of the Sarbanes-Oxley Act.

Note 3
Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against

Tax-Advantaged Dividend Income Fund

18


certain liability arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general 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. However, based on experience, the Fund believes the risk of loss to be remote.

Auction preferred shares

The Fund issued total of 15,200 Auction Preferred Shares (3,800 shares of Series M, 3,800 shares of Series W, 3,800 of shares of Series TH and 3,800 shares of Series F) (collectively, the APS) on May 3, 2004, in a public offering. The underwriting discount of $3,800,000 and offering costs of $396,310 incurred in connection with the preferred shares and offering cost of $854,726 related to common shares were charged to capital paid-in of common shares during the period ended December 31, 2004.

Dividends on the APS, which accrue daily, are cumulative at a rate that was established at the offering of the APS and has been reset every seven days thereafter by an auction. During the period ended June 30, 2007, dividend rates on APS ranged as follows: Series M from 4.10% to 4.70%, Series W from 3.90% to 4.75%, Series TH from 4.00% to 4.70% and Series F from 3.80% to 4.75% . Accrued dividends on APS, if any, are included in the value of APS on the Fund’s Statement of Assets and Liabilities.

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 on its asset coverage requirements with respect to the APS as defined in the Fund’s bylaws. Under the 1940 Act, the Fund is required to maintain asset coverage of at least 200% with respect to the APS as of the last business day of each month in which the shares are outstanding. 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 shareholders have equal voting rights of one vote per share, except that the holders of the APS, as a class, vote to elect two members of the Board of Trustees, and separate class votes are required on certain matters that affect the respective interests of the APS and common shareholders.

Leverage

The Fund issued preferred shares to increase its assets available for investment. The Fund generally will not issue preferred shares unless the Adviser expects that the Fund will achieve a greater return on the proceeds resulting from the use of leverage than the additional costs the Fund incurs as a result of leverage. When

Tax-Advantaged Dividend Income Fund

19


the Fund leverages its assets, the fees paid to the Adviser for investment advisory and administrative services will be higher than if the Fund did not borrow because the Adviser’s fees are calculated based on the Fund’s total assets, including the proceeds of the issuance of preferred shares. Consequently, the Fund and the Adviser may have differing interests in determining whether to leverage the Fund’s assets. The Board of Trustees will monitor this potential conflict. The Fund’s use of leverage is premised upon the expectation that the Fund’s dividends on its outstanding preferred shares will be lower than the return the Fund achieves on its investments with the proceeds of the issuance of preferred shares.

Leverage creates risks which may adversely affect the return for the holders of common shares, including:

• the likelihood of greater volatility of net asset value and market price of common shares

• fluctuations in the dividend rates on any preferred shares

• increased operating costs, which may reduce the Fund’s total return to the holders of common shares

• the potential for a decline in the value of an investment acquired through leverage, while the Fund’s obligations under such leverage remains fixed

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage; the Fund’s return will be greater than if leverage had not been used.

Note 5
Investment transactions

Purchases and proceeds from sales or maturities of securities, other than short-term securities and obligations of the U.S. government, during the period ended June 30, 2007, aggregated $268,029,731 and $290,888,327, respectively.

The cost of investments owned on June 30, 2007, including short-term investments, for federal income tax purposes, was $1,206,759,940. Gross unrealized appreciation and depreciation of investments aggregated $131,773,168 and $22,972,411, respectively, resulting in net unrealized appreciation of $108,800,757. The difference between book basis and tax basis net unrealized appreciation of investments is attributable primarily to the tax deferral of losses on certain sales of securities.

Tax-Advantaged Dividend Income Fund

20


Investment objective and policy

The Fund’s investment objective is to provide a high level of after-tax total return from dividend income and capital appreciation.

Under normal market conditions, the Fund will invest at least 80% of its assets (net assets plus borrowings for investment purposes) in dividend-paying common and preferred securities that the Adviser believes at the time of acquisition are eligible to pay dividends which, for individual shareholders, qualify for U.S. federal income taxation at rates applicable to long-term capital gains, which currently are taxed at a maximum rate of 15% (“tax-advantaged dividends”). Tax-advantaged dividends generally include dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria. The Fund generally can pass the tax treatment of tax-advantaged dividends it receives through to its common shareholders.

Dividends and distributions

During the year ended December 31, 2006, dividends from net investment income totaling $1.1604 and distributions from capital gains totaling $0.5321 per share were paid to common shareholders. The dates of payments and the amounts per share are as follows:

Dividend reinvestment plan

The Fund offers its shareholders a Dividend Reinvestment Plan (the Plan), which offers the opportunity to earn compounded yields. Each holder of common shares may elect to have all distributions of dividends and capital gains reinvested by Mellon Investor Services, as plan agent for the common shareholders (the Plan Agent). Holders of common shares who do not elect to participate in the Plan will receive all distributions in cash, paid by check mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to the nominee) by the Plan Agent, as dividend disbursing agent.

Shareholders may join the Plan by filling out and mailing an authorization card, by notifying the Plan Agent by telephone or by visiting the Plan Agent’s Web site at www.melloninvestor.com. Shareholders must indicate an election to reinvest all or a portion of dividend payments. If received in proper form by the Plan Agent before the record date of a dividend, the election will be effective with respect to all dividends paid after such record date. Shareholders whose shares are held in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan.

If the Fund declares a dividend payable either in common shares or in cash, nonparticipants will receive cash, and participants in the Plan will receive the equivalent in common shares. If the market price of the common shares on the payment date of the dividend is equal to or exceeds their net asset value as determined on the payment date, participants will be issued common shares (out of authorized but unissued shares) at a value equal to the higher of net asset value or 95% of the market price. If the net asset value exceeds the market price of the common shares at such time, or if the Board of Trustees declares a dividend payable only in cash, the Plan Agent will, as agent for Plan participants, buy shares in the open market, on the New York Stock Exchange or elsewhere, for the participants’ accounts. Such purchases will be made promptly after the payable date for such dividend and, in any event, prior to the next ex-dividend date after such date, except where necessary to comply with federal securities laws. If, before the Plan Agent has completed its purchases, the market price exceeds the net asset value of the common shares, the average per share purchase price paid by the Plan Agent

21


may exceed the net asset value of the common shares, resulting in the acquisition of fewer shares than if the dividend had been paid in shares issued by the Fund.

Each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open market purchases in connection with the reinvestment of dividends and distributions. In each case, the cost per share of the shares purchased for each participant’s account will be the average cost, including brokerage commissions, of any shares purchased on the open market plus the cost of any shares issued by the Fund. There will be no brokerage charges with respect to common shares issued directly by the Fund. There are no other charges to participants for reinvesting dividends or capital gain distributions.

Participants in the Plan may withdraw from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.melloninvestor.com. Such withdrawal will be effective immediately if received not less than ten days prior to a dividend record date; otherwise, it will be effective for all subsequent dividend record dates. When a participant withdraws from the Plan or upon termination of the Plan, as provided below, certificates for whole common shares credited to his or her account under the Plan will be issued, and a cash payment will be made for any fraction of a share credited to such account.

The Plan Agent maintains each shareholder’s account in the Plan and furnishes monthly written confirmations of all transactions in the accounts, including information needed by the shareholders for personal and tax records. The Plan Agent will hold common shares in the account of each Plan participant in noncertificated form in the name of the participant. Proxy material relating to the shareholders’ meetings of the Fund will include those shares purchased as well as shares held pursuant to the Plan.

The reinvestment of dividends and distributions will not relieve participants of any federal income tax that may be payable or required to be withheld on such dividends or distributions. Participants under the Plan will receive tax information annually. The amount of dividend to be reported on 1099-DIV should be (1) in the case of shares issued by the Fund, the fair market value of such shares on the dividend payment date and (2) in the case of shares purchased by the Plan Agent in the open market, the amount of cash used by the Plan Agent to purchase shares in the open market, including the amount of cash allocated to brokerage commissions paid on such purchases.

Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan as applied to any dividend or distribution paid subsequent to written notice of the change sent to all shareholders of the Fund at least 90 days before the record date for the dividend or distribution. The Plan may be amended or terminated by the Plan Agent after at least 90 days’ written notice to all shareholders of the Fund. All correspondence or additional information concerning the Plan should be directed to the Plan Agent, Mellon Bank, N.A., c/o Mellon Investor Services, P.O. Box 3338, South Hackensack, NJ 07606-1938 (Telephone: 1-800-852-0218).

Board Consideration of and
Continuation of Investment Advisory
Agreement and Subadvisory
Agreement: John Hancock Tax-
Advantaged Dividend Income Fund

The Investment Company Act of 1940 (the 1940 Act) requires the Board of Trustees (the Board) of John Hancock Tax-Advantaged Dividend Income Fund (the Fund), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not “interested persons” of the Fund, as defined in the 1940 Act (the Independent Trustees), annually to meet in person to review and consider the continuation of: (i) the investment advisory agreement (the Advisory Agreement) with John Hancock Advisers, LLC (the Adviser) and (ii) the investment subadvisory agreement (the Subadvisory Agreement) with MFC Global Investment Management (U.S.), LLC (the Subadviser). The Advisory Agreement and the Subadvisory Agreement are collectively referred to as the Advisory Agreements.

At meetings held on May 7 and June 4–5, 2007, the Board considered the factors and reached the conclusions described below relating to the selection of the Adviser and Subadviser and the continuation of the Advisory Agreements. During such meetings, the Board’s Contracts/ Operations Committee and the Independent Trustees also met in executive sessions with their independent legal counsel.

In evaluating the Advisory Agreements, the Board, including the Contracts/Operations Committee and the Independent Trustees, reviewed a broad range of information requested for this purpose by the Independent Trustees, including: (i) the investment performance of the Fund relative to a category of relevant funds (the Category) and a peer group of comparable funds (the Peer Group) each selected by Morningstar, Inc. (Morningstar), an independent provider of investment company data, for a range of periods ended December 31, 2006, (ii) advisory and other fees incurred by, and the expense ratios of, the Fund relative to a Category and a Peer Group, (iii) the advisory fees of comparable portfolios of other clients of the Adviser and the Subadviser, (iv) the Adviser’s financial results and condition, including its and certain of its affiliates’ profitability from services performed for the Fund, (v) breakpoints in the Fund’s and the Peer Group’s fees, and information about economies of scale, (vi) the Adviser’s and Subadviser’s record of compliance with applicable laws and regulations, with the Fund’s investment policies and restrictions, and with the applicable Code of Ethics, and the structure and responsibilities of the Adviser’s and Subadviser’s compliance department, (vii) the background and experience of senior management and investment professionals, and (viii) the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates and by the Subadviser.

The Independent Trustees considered the legal advice of independent legal counsel and relied on their own business judgment in determining the factors to be considered in evaluating the materials that were presented to them and the weight to be given to each such factor. The Board’s review and conclusions were based on a comprehensive consideration of all information presented to the Board and not the result of any single controlling factor. They principally considered performance and other information from Morningstar as of December 31, 2006. The Board also considered updated performance information provided to it by the Adviser or Subadviser at the May and June 2007 meetings. Performance and other information may be quite different as of the date of this shareholders report. The key factors considered by the Board and the conclusions reached are described below.

Nature, extent and quality of services

The Board considered the ability of the Adviser and the Subadviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory and supervisory personnel. The Board considered the investment philosophy, research and investment decision-making processes of the Adviser and Subadviser. The Board further considered the culture of compliance, resources dedicated to compliance, compliance programs and compliance records of the Adviser and Subadviser. In addition, the

24


Board took into account the administrative and other non-advisory services provided to the Fund by the Adviser and its affiliates.

Based on the above factors, together with those referenced below, the Board concluded that, within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser and Subadviser supported renewal of the Advisory Agreements.

Fund performance

The Board noted that the Fund had less than three full years of operational history, and considered the performance results for the Fund since its inception in 2004 through December 31, 2006. The Board also considered these results in comparison to the performance of the Category, as well as the Fund’s Peer Group and benchmark index. Morningstar determined the Category and Peer Group for the Fund. The Board reviewed with a representative of Morningstar the methodology used by Morningstar to select the funds in the Category and the Peer Group. The Board noted the imperfect comparability of the Peer Group.

The Board noted that the Fund’s performance was lower than the performance of the Category and Peer Group medians, but was higher than the performance of its benchmark index, the Merrill Lynch Preferred Stock Drd Eligible Index, over the one-year period. The Board recognized the short operational history of the Fund and indicated its intent to continue to monitor the Fund’s performance trends.

Investment advisory fee and subadvisory fee rates and expenses

The Board reviewed and considered the contractual investment advisory fee rate payable by the Fund to the Adviser for investment advisory services (the Advisory Agreement Rate). The Board received and considered information comparing the Advisory Agreement Rate with the advisory fees for the Category and Peer Group. The Board noted that the Advisory Agreement Rate was lower than the median rate of the Category and Peer Group. The Board favorably considered the Adviser’s agreement to continue fee waivers, which lowered the Advisory Agreement Rate.

The Board received and considered expense information regarding the Fund’s various components, including advisory fees, and other non-advisory fees, including transfer agent fees, custodian fees and other miscellaneous fees (e.g., fees for accounting and legal services). The Board considered comparisons of these expenses to the Peer Group median. The Board also received and considered expense information regarding the Fund’s total operating expense ratio (Gross Expense Ratio) and total operating expense ratio after taking the fee waiver arrangement applicable to the Advisory Agreement Rate into account (Net Expense Ratio). The Board received and considered information comparing the Gross Expense Ratio and Net Expense Ratio of the Fund to that of the Peer Group and Category medians. The Board noted that the Fund’s Gross and Net Expense Ratios were lower than the Category and Peer Group medians. The Board favorably considered the impact of the fee waivers towards ultimately lowering the Fund’s total operating expense ratio.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for the Fund. Based on the above-referenced considerations and other factors, the Board concluded that the Fund’s overall expense results and performance supported the re-approval of the Advisory Agreements.

The Board also received information about the investment subadvisory fee rate (the Subadvisory Agreement Rate) payable by the Adviser to the Subadviser for investment sub-advisory services. The Board concluded that the Subadvisory Agreement Rate was fair and equitable, based on its consideration of the factors described here.

Profitability

The Board received and considered a detailed profitability analysis of the Adviser based on the Advisory Agreements, as well as on other relationships between the Fund and the Adviser and its affiliates, including the Subadviser. The Board also considered a comparison of the Adviser’s profitability to that of other similar investment advisers whose profit-ability information is publicly available. The Board concluded that, in light of the costs of

25


providing investment management and other services to the Fund, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

Economies of scale

The Board received and considered general information regarding economies of scale with respect to the management of the Fund, including the Fund’s ability to appropriately benefit from economies of scale under the Fund’s fee structure. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s and Subadviser’s costs are not specific to individual Funds, but rather are incurred across a variety of products and services.

The Board observed that the Advisory Agreements did not offer breakpoints. However, the Board considered the limited relevance of economies of scale in the context of a closed-end fund that, unlike an open-end fund, does not continuously offer its shares. The Board noted that the Fund, as a closed-end investment company, was not expected to increase materially in size and that its assets would grow (if at all) through the investment performance of the Fund. Therefore, the Board did not consider potential economies of scale as a principal factor in assessing the fees payable under the Advisory Agreements, but concluded that the fees were fair and equitable based on relevant factors.

Other benefits to the Adviser

The Board received information regarding potential “fall-out” or ancillary benefits received by the Adviser and its affiliates as a result of the Adviser’s relationship with the Fund. Such benefits could include, among others, benefits directly attributable to the relationship of the Adviser with the Fund and benefits potentially derived from an increase in the business of the Adviser as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s, Subadviser’s and Fund’s policies and procedures for complying with the requirements of the federal securities laws, including those relating to best execution of portfolio transactions and brokerage allocation.

Other factors and broader review

As discussed above, the Board reviewed detailed materials received from the Adviser and Subadviser as part of the annual re-approval process. The Board also regularly reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of the Adviser and Subadviser at least quarterly, which include, among other things, fund performance reports and compliance reports. In addition, the Board meets with portfolio managers and senior investment officers at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information described above, the Board concluded that approval of the continuation of the Advisory Agreements for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously approved the continuation of the Advisory Agreements.
