A message to shareholders

Dear shareholder,

The past six months proved to be a challenging time for U.S. equity investors. Many market indexes tumbled in the winter months amid concerns about slowing global growth, particularly in China. The volatility extended to commodity markets, as oil prices hit multi-year lows in February before rebounding toward the end of the period. The investment landscape improved late in the period as stocks and other so-called risk assets regained positive momentum and most U.S. indexes finished the period with modest gains.

Volatile market environments are naturally unsettling. But despite the recent turbulence, we believe the economic picture in the United States offers reasons for optimism. Unemployment and inflation both remain low, while the housing market and consumer demand have both shown signs of resilience. Nonetheless, the volatility that characterized the markets at the start of the year could be with us for some time.

At John Hancock Investments, portfolio risk management is a critical part of our role as an asset manager, and our dedicated risk team is focused on these issues every day. We continually strive for new ways to analyze potential risks and to ensure that we have adequate liquidity tools in place. As always, your best resource in times like these is your financial advisor, who can help make sure your portfolio is sufficiently diversified to meet your long-term objectives and to withstand the inevitable bumps along the way.

On behalf of everyone at John Hancock Investments, I'd like to take this opportunity to thank you for the continued trust you've placed in us.

Sincerely,

Andrew G. Arnott
President and Chief Executive Officer
John Hancock Investments

INVESTMENT OBJECTIVE

The fund seeks to provide a high level of after-tax total return from dividend income and gains and capital appreciation.

AVERAGE ANNUAL TOTAL RETURNS AS OF 4/30/16 (%)

The index shown is a blended index that is 55% Bank of America Merrill Lynch Preferred Stock DRD Eligible Index and 45% S&P 500 Utilities Index.

The Bank of America Merrill Lynch Preferred Stock DRD Eligible Index consists of investment-grade fixed-rate U.S. dollar-denominated preferred securities and fixed-to-floating-rate securities. The index includes securities having a minimum remaining term of at least one year, Dividend Received Deduction (DRD) eligible preferred stock and senior debt.

The S&P 500 Utilities Index is a capitalization-weighted index that consists of companies in the S&P 500 Index that are primarily involved in water, electrical power, and natural gas distribution industries.

It is not possible to invest directly in an index. Index figures do not reflect expenses or sales charges, which would result in lower returns.

The fund's most recent performance and current annualized distribution rate can be found at jhinvestments.com.

If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

PERFORMANCE HIGHLIGHTS OVER THE LAST SIX MONTHS

Dividend-paying securities generated solid gains

Falling interest rates outside of the United States, fears of a recession, and heightened stock market volatility stoked demand for utilities, energy-related common stocks, and preferred securities.

Energy-related holdings performed well

Pipeline company holdings benefited from a rebound in oil prices, as well as investors' growing demand for energy companies whose revenues are driven by fees rather than commodity prices.

Foreign banks detracted

Negative interest rates in Europe and Japan eroded bank earnings.

PORTFOLIO COMPOSITION AS OF 4/30/16 (%)

A note about risks

As is the case with all closed-end funds, shares of this fund may trade at a discount or a premium to the fund's net asset value (NAV). An investment in the fund is subject to investment and market risks, including the possible loss of the entire principal invested. There is no guarantee prior distribution levels will be maintained, and distributions may include a substantial return of capital. Fixed-income investments are subject to interest-rate and credit risk; their value will normally decline as interest rates rise or if a creditor, grantor, or counterparty is unable or unwilling to make principal, interest, or settlement payments. Investments in higher-yielding, lower-rated securities are subject to a higher risk of default. An issuer of securities held by the fund may default, have its credit rating downgraded, or otherwise perform poorly, which may affect fund performance. Liquidity—the extent to which a security may be sold or a derivative position closed without negatively affecting its market value, if at all—may be impaired by reduced trading volume, heightened volatility, rising interest rates, and other market conditions. The fund's use of leverage creates additional risks, including greater volatility of the fund's NAV, market price, and returns. There is no assurance that the fund's leverage strategy will be successful. Focusing on a particular industry or sector may increase the fund's volatility and make it more susceptible to market, economic, and regulatory risks as well as other factors affecting those industries or sectors. Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Discussion of fund performance

An interview with Portfolio Manager Gregory K. Phelps, John Hancock Asset Management a division of Manulife Asset Management (US) LLC

Gregory K. Phelps
Portfolio Manager
John Hancock Asset Management

What was the market environment like for dividend-paying securities during the six months ended April 30, 2016?

Dividend-paying securities—which are traditionally viewed as a more attractive investment during times of economic uncertainty, heightened market volatility, and low interest rates—generated solid gains. At the beginning of the period, many dividend-paying stocks were under pressure in response to expectations that U.S. interest rates were poised to rise. Instead, long-term interest rates fell in early 2016, making income-producing investments relatively more attractive to many investors. As compensation for their higher risk, dividend-paying securities tend to pay more than comparable bonds. Fears of recession, which were felt most acutely in February, further stoked demand for dividend-paying securities, offering haven to investors seeking refuge from significant declines in broader stock market averages.

While utility securities benefited the most from those trends, other segments of the dividend-paying universe were further bolstered by factors unique to their respective sectors. Energy common stocks, for example, enjoyed a partial, yet impressive, rebound from their extremely poor performance in 2015. Oil prices moved higher, leading bargain-seeking investors looking to the energy sector with expectations that revenue and earnings could rebound as well if the current oil glut dwindled as production halts started to weigh on supply. Preferred securities were helped by muted new issuance, as most issuers refrained from bringing new preferred securities to the marketplace. With common stock dividend cuts continuing to accelerate during the past six months, there was growing demand for preferred dividend payouts, which have precedence over common stock dividends. While financial stocks were generally down for the period, many financial preferreds, led by U.S. banks, also fared comparatively well, as they restructured and strengthened their capital structures since the 2007/2008 financial crisis.

What's your view on dividend-paying securities?

Given their strong gains during the prior six months, dividend-paying securities ended the period less attractively valued than they were at the beginning of the period; their upside may be limited over the short term. That said, we believe dividend-paying securities can hold on to their recent

"Dividend-paying securities—which are traditionally viewed as a more attractive investment during times of economic uncertainty, heightened market volatility, and low interest rates—generated solid gains."
gains for the balance of 2016. The U.S. Federal Reserve (Fed) has lowered its forward rate hike guidance to indicate a more gradual pace than the central bank had suggested at the end of 2015. Given the Fed's more dovish tone, our view is that rate hikes in 2016 will be few and far between, totaling one or two 0.25% increases and most likely occurring in the second half of the year. In our view, dividend-paying securities should be able to weather a couple of small and gradual increases in the federal funds rate. Furthermore, low long-term U.S. Treasury yields make the comparatively high yields offered by dividend-paying securities more attractive to income-seeking investors. Muted supply should also be supportive. We don't foresee any meaningful uptick in the supply of dividend-paying preferred or common stocks on the horizon.

What holdings contributed to performance?

Some of the portfolio's energy-related investments were among its best performers for the six-month period. Pipeline companies, such as the common stock of Spectra Energy Corp. and Columbia Pipeline Group, Inc., performed quite well. Investors began to recognize that pipeline company revenues were fee based rather than commodity price dependent. Spectra's decision to raise its dividend in February was a plus for that holding. Columbia Pipeline rallied further on the mid-March announcement of its planned merger with TransCanada Corporation. Also in the energy sector, Chevron Corp. and ONEOK, Inc. generated positive returns.

"In our view, dividend-paying securities should be able to weather a couple of small and gradual increases in the federal funds rate."

Among holdings in the utilities sector, Black Hills Corp. was one of the portfolio's standouts. The company completed the acquisition of a natural gas utility expected to enhance regulated earnings and lower its risk profile. Other positive performers in this sector included Alliant Energy Corp., Talen Energy Corp., and Questar Corp.

What hurt the fund's performance?

Detracting from the fund's results was the preferred stock of Deutsche Bank Contingent Capital Trust. Interest rates in some Eueropean countries went negative during the period, eroding bank earnings on the Continent; concerns about nonperforming loans also weighed on the stock. Another disappointment was the preferred stock of DTE Energy Company, whose price languished as it moved closer to its potential December 2016 call date. Given that the company can call these securities at par at year end, their upside potential was limited. Conoco Phillips and Kinder Morgan Inc. also generated negative returns. Our use of derivative such as futures, options, and swaps also had a negative impact on performance.

Were there any significant changes to the portfolio?

At about midpoint in the period, we sold some of the fund's lower-yielding utility holdings at prices we viewed as attractive given the very strong demand for such stocks at the time. In many cases, we used the proceeds from those sales to purchase more of the higher-yielding pipeline companies the fund already held, including Spectra. We felt that these securities were very attractively valued, especially given our view that oil prices had bottomed at that time and were set to move higher. We

Notes to financial statements (unaudited)

Note 1 — Organization

John Hancock Tax-Advantaged Dividend Income (the fund) is a closed-end management investment company organized as a Massachusetts business trust and registered under the Investment Company Act of 1940, as amended (the 1940 Act).

Note 2 — Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP), which require management to make certain estimates and assumptions as of the date of the financial statements. Actual results could differ from those estimates and those differences could be significant. The fund qualifies as an investment company under Topic 946 of Accounting Standards Codification of US GAAP.

Events or transactions occurring after the end of the fiscal period through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the fund:

Security valuation. Investments are stated at value as of the scheduled close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 p.m., Eastern Time. In case of emergency or other disruption resulting in the NYSE not opening for trading or the NYSE closing at a time other than the regularly scheduled close, the net asset value (NAV) may be determined as of the regularly scheduled close of the NYSE pursuant to the fund's Valuation Policies and Procedures. The time at which shares and transactions are priced and until which orders are accepted may vary to the extent permitted by the Securities and Exchange Commission and applicable regulations.

In order to value the securities, the fund uses the following valuation techniques: Equity securities held by the fund are typically valued at the last sale price or official closing price on the exchange or principal market where the security was acquired or most likely will be sold. In the event there were no sales during the day or closing prices are not available, the securities are valued using the last available bid price. Debt obligations are valued based on the evaluated prices provided by an independent pricing vendor or from broker-dealers. Independent pricing vendors utilize matrix pricing which takes 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, as well as broker supplied prices. Options listed on an exchange are valued at the mean of the most recent bid and ask prices from the exchange where the option was acquired or most likely will be sold. Swaps are valued using evaluated prices obtained from an independent pricing vendor. Futures contracts are valued at settlement prices, which are the official closing prices published by the exchange on which they trade. Foreign securities are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing vendor.

In certain instances, the Pricing Committee may determine to value equity securities using prices obtained from another exchange or market if trading on the exchange or market on which prices are typically obtained did not open for trading as scheduled, or if trading closed earlier than scheduled, and trading occurred as normal on another exchange or market.

Other portfolio securities and assets, for which reliable market quotations are not readily available, are valued at fair value as determined in good faith by the fund's Pricing Committee following procedures established by the Board of Trustees. The frequency with which these fair valuation procedures are used cannot be predicted and fair value of securities may differ significantly from the value that would have been used had a ready market for such securities existed.

The fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using other significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily available or reliable, including the fund's own assumptions in determining the fair value of investments. Factors used in determining value may include market or issuer specific events or trends, changes in interest rates and credit quality. The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Changes in valuation techniques and related inputs may result in transfers into or out of an assigned level within the disclosure hierarchy.

Repurchase agreements. The fund may enter into repurchase agreements. When the fund enters into a repurchase agreement, it receives collateral that is held in a segregated account by the fund's custodian. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. Collateral received by the fund for repurchase agreements is disclosed in the Fund's investments as part of the caption related to the repurchase agreement.

Repurchase agreements are typically governed by the terms and conditions of the Master Repurchase Agreement and/or Global Master Repurchase Agreement (collectively, MRA). Upon an event of default, the non-defaulting party may close out all transactions traded under the MRA and net amounts owed. Absent an event of default, assets and liabilities resulting from repurchase agreements are not offset in the Statement of assets and liabilities. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline or the counterparty may have insufficient assets to pay back claims resulting from close-out of the transactions.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily NAV calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful. Dividend income is recorded on the ex-date, except for dividends of foreign securities where the dividend may not be known until after the ex-date. In those cases, dividend income, net of withholding taxes, is recorded when the fund becomes aware of the dividends. Foreign taxes are provided for based on the fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 19

Foreign taxes. The fund may be subject to withholding tax on income and/or capital gains or repatriation taxes imposed by certain countries in which the fund invests. Taxes are accrued based upon investment income, realized gains or unrealized appreciation.

Overdrafts. Pursuant to the custodian agreement, the fund's custodian may, in its discretion, advance funds to the fund to make properly authorized payments. When such payments result in an overdraft, the fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian may have a lien, security interest or security entitlement in any fund property that is not otherwise segregated or pledged, to the maximum extent permitted by law, to the extent of any overdraft.

Expenses. Within the John Hancock group of funds complex, expenses that are directly attributable to an individual fund are allocated to such fund. Expenses that are not readily attributable to a specific fund are allocated among all funds in an equitable manner, taking into consideration, among other things, the nature and type of expense and the fund's relative net assets. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Federal income taxes. The fund intends to continue to qualify 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.

Under the Regulated Investment Company Modernization Act of 2010, the fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Any losses incurred during those taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

For federal income tax purposes, as of October 31, 2015, the fund has a capital loss carryforward of $5,580,087 available to offset future net realized capital gains, which expires on October 31, 2017.

As of October 31, 2015, the fund had no uncertain tax positions that would require financial statement recognition, derecognition or disclosure. The fund's federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The fund generally declares and pays dividends monthly and capital gain distributions, if any, annually.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from US GAAP. The final determination of tax characteristics of the fund's distribution will occur at the end of the fiscal year and will subsequently be reported to shareholders.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period. Book-tax differences are primarily attributable to wash sale loss deferrals and derivative transactions.

Statement of cash flows. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Statement of cash flows. The cash amount shown in the Statement of cash flows is the amount included in the fund's Statement of assets and liabilities and represents the cash on hand at the fund's custodian and does not include any short-term investments, cash segregated at the custodian for derivative contracts or cash held at broker for futures contracts.

Note 3 — Derivative instruments

The fund may invest in derivatives in order to meet its investment objectives. Derivatives include a variety of different instruments that may be traded in the OTC market, on a regulated exchange or through a clearing facility. The risks in using derivatives vary depending upon the structure of the instruments, including the use of leverage, optionality, the liquidity or

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 20

lack of liquidity of the contract, the creditworthiness of the counterparty or clearing organization and the volatility of the position. Some derivatives involve risks that are potentially greater than the risks associated with investing directly in the referenced securities or other referenced underlying instrument. Specifically, the fund is exposed to the risk that the counterparty to an OTC derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction.

Certain swaps are typically traded through the OTC market. Derivative counterparty risk is managed through an ongoing evaluation of the creditworthiness of all potential counterparties and, if applicable, designated clearing organizations. The fund attempts to reduce its exposure to counterparty risk for derivatives traded in the OTC market, whenever possible, by entering into an International Swaps and Derivatives Association (ISDA) Master Agreement with each of its OTC counterparties. The ISDA gives each party to the agreement the right to terminate all transactions traded under the agreement if there is certain deterioration in the credit quality or contractual default of the other party, as defined in the ISDA. Upon an event of default or a termination of the ISDA, the non-defaulting party has the right to close out all transactions and to net amounts owed.

As defined by the ISDA, the fund may have collateral agreements with certain counterparties to mitigate counterparty risk on OTC derivatives. Subject to established minimum levels, collateral for OTC transactions is generally determined based on the net aggregate unrealized gain or loss on contracts with a particular counterparty. Collateral pledged to the fund is held in a segregated account by a third-party agent or held by the custodian bank for the benefit of the fund and can be in the form of cash or debt securities issued by the U.S. government or related agencies; collateral posted by the fund for OTC transactions is held in a segregated account at the fund's custodian and is noted in the accompanying Fund's investments, or if cash is posted, on the Statement of assets and liabilities. The fund's maximum risk of loss due to counterparty risk is equal to the asset value of outstanding contracts offset by collateral received.

Futures and certain options are traded or cleared on an exchange. Exchange-traded or cleared transactions generally present less counterparty risk to a fund than OTC transactions. The exchange stands between the fund and the broker to the contract and therefore, credit risk is generally limited to the failure of the exchange or clearinghouse and the clearing member.

Futures. A futures contract is a contractual agreement to buy or sell a particular currency or financial instrument at a pre-determined price in the future. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in the underlying financial instrument and potential losses in excess of the amounts recognized on the Statement of assets and liabilities. Use of long futures contracts subjects the fund to the risk of loss up to the notional value of the futures contracts. Use of short futures contracts subjects the fund to unlimited risk of loss.

Upon entering into a futures contract, the fund is required to deposit initial margin with the broker in the form of cash or securities. The amount of required margin is generally based on a percentage of the contract value; this amount is the initial margin for the trade. The margin deposit must then be maintained at the established level over the life of the contract. Futures margin receivable / payable is included on the Statement of assets and liabilities. Futures contracts are marked-to-market daily and an appropriate payable or receivable for the change in value (variation margin) and unrealized gain or loss is recorded by the fund. When the contract is closed, the fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

During the six months ended April 30, 2016, the fund used futures contracts to manage against anticipated interest rate changes.

Options. There are two types of options, put options and call options. Options are traded either OTC or on an exchange. A call option gives the purchaser of the option the right to buy (and the seller the obligation to sell) the underlying instrument at the exercise price. A put option gives the purchaser of the option the right to sell (and the writer the obligation to buy) the underlying instrument at the exercise price. Writing puts and buying calls may increase the fund's exposure to changes in the value of the underlying instrument. Buying puts and writing calls may decrease the fund's exposure to such changes. Risks related to the use of options include the loss of premiums, possible illiquidity of the options markets, trading restrictions imposed by an exchange and movements in underlying security values, and for written options, potential losses in excess of the amounts recognized on the Statement of assets and liabilities. In addition, OTC options are subject to the risks of all OTC derivatives contracts.

When the fund purchases an option, the premium paid by the fund is included in the Fund's investments and subsequently "marked-to-market" to reflect current market value. If the purchased option expires, the fund realizes a loss equal to the cost of the option. If the fund enters into a closing sale transaction, the fund realizes a gain or loss, depending on whether proceeds from the closing sale are greater or less than the original cost. When the fund writes an option, the premium received is included as a liability and subsequently "marked-to-market" to reflect the current market value of the option written. Premiums received from writing options that expire unexercised are recorded as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option on a security is exercised, the premium received reduces the cost basis of the securities purchased by the fund.

During the six months ended April 30, 2016, the fund wrote option contracts to hedge against anticipated changes in securities markets and to generate potential income. The following tables summarize the fund's written options activities during the six months ended April 30, 2016 and the contracts held at April 30, 2016:

|  |  |  | Number of contracts |  |  | Premiums received |

Interest rate swaps. Interest rate swaps represent an agreement between the fund and a counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The fund settles accrued net interest receivable or payable under the swap contracts at specified, future intervals. Swap agreements are privately negotiated in the OTC market or may be executed on a registered commodities exchange (centrally cleared swaps). Swaps are marked-to-market daily and the change in value is recorded as unrealized appreciation/depreciation of swap contracts. A termination payment by the counterparty or the fund is recorded as realized gain or loss, as well as the net periodic payments received or paid by the fund. The value of the swap will typically impose collateral posting obligations on the party that is considered out-of-the-money on the swap.

Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may amount to values that are in excess of the amounts recognized on the Statement of assets and liabilities. Such risks involve

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 22

the possibility that there will be no liquid market for the swap, or that a counterparty may default on its obligation or delay payment under the swap terms. The counterparty may disagree or contest the terms of the swap. Market risks may also accompany the swap, including interest rate risk. The fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.

During the six months ended April 30, 2016, the fund used interest rate swaps to manage against anticipated interest rate changes. The following table summarizes the interest rate swap contracts held as of April 30, 2016:

| Counterparty |  |  | USD notional amount |  |  | Payments made by fund |  |  | Payments received by fund |  |  | Maturity date |  |  | Market value |
| Morgan Stanley Capital Services |  |  | $86,000,000 |  |  | Fixed 1.4625% |  |  | 3-Month LIBOR (a) |  |  | Aug 2016 |  |  | ($358,733 | )

(a) At 4-30-16, 3-Month LIBOR was 0.6366%

No interest rate swap positions were entered into or closed during the six months ended April 30, 2016.

Note 4 — Guarantees and indemnifications

Under the fund's organizational documents, its Officers and Trustees are indemnified against certain liabilities 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. The risk of material loss from such claims is considered remote.

Note 5 — Fees and transactions with affiliates

John Hancock Advisers, LLC (the Advisor) serves as investment advisor for the fund. The Advisor is an indirect, wholly owned subsidiary of Manulife Financial Corporation (MFC).

Management fee. The fund has an investment management agreement with the Advisor under which the fund pays a daily management fee to the Advisor equivalent on an annual basis to 0.75% of the fund's average daily managed assets (net assets plus borrowings under the Liquidity Agreement (the LA)) (see Note 8). The Advisor has a subadvisory agreement with John Hancock Asset Management a division of Manulife Asset Management (US) LLC, an indirectly owned subsidiary of MFC and an affiliate of the Advisor, and a subadvisory agreement with Analytic Investors, LLC. The fund is not responsible for payment of the subadvisory fees.

The Advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock group of funds complex, including the fund (the participating portfolios). This waiver is based upon aggregate net assets of all the participating portfolios. The amount of the reimbursement is calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each fund. During the six months ended April 30, 2016, this waiver amounted to 0.01% of the fund's average daily managed assets (on an annualized basis). This arrangement may be amended or terminated at any time by the Advisor upon notice to the fund and with the approval of the Board of Trustees.

The expense reductions described above amounted to $45,714 for the six months ended April 30, 2016.

Expenses waived or reimbursed in the current fiscal period are not subject to recapture in future fiscal periods.

The investment management fees, including the impact of the waivers and reimbursements as described above, incurred for the six months ended April 30, 2016 were equivalent to a net annual effective rate of 0.74% of the fund's average daily managed assets.

Accounting and legal services. Pursuant to a service agreement, the fund reimburses the Advisor for all expenses associated with providing the administrative, financial, legal, accounting and recordkeeping services to the fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports, among other services. These accounting and legal services fees incurred for the six months ended April 30, 2016 amounted to an annual rate of 0.02% of the fund's average daily managed assets.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates. These Trustees receive from the fund and the other John Hancock closed-end funds an annual retainer. In addition, Trustee out-of-pocket expenses are allocated to each fund based on its net assets relative to other funds within the John Hancock group of funds complex.

Note 6 — Fund share transactions

In December 2007, the Board of Trustees approved a share repurchase plan, which was subsequently reviewed and approved by the Board of Trustees each year in December. Under the current share repurchase plan, the fund may purchase in the open market up to 10% of its outstanding common shares as of December 31, 2015. The current share repurchase plan will remain in effect between January 1, 2016 and December 31, 2016.

During the six months ended April 30, 2016 and year ended October 31, 2015, the fund repurchased 0.91% and 3.62% of its common shares outstanding under the repurchase program, respectively. The weighted average discount per share on these repurchases amount to 11.56% and 11.10% for the six months ended April 30, 2016 and year ended October 31,

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 24

2015, respectively. Shares repurchased and corresponding dollar amounts are included on the Statements of changes in net assets. The anti-dilutive impacts of these share repurchases are included on the Financial highlights.

Note 7 — Leverage risk

The fund utilizes the LA to increase its assets available for investment. When the fund leverages its assets, common shareholders bear the fees associated with the LA and have potential to benefit or be disadvantaged from the use of leverage. The Advisor's fee is also increased in dollar terms from the use of leverage. Consequently, the fund and the Advisor may have differing interests in determining whether to leverage the fund's assets. Leverage creates risks that may adversely affect the return for the holders of common shares, including:

• | the likelihood of greater volatility of NAV and market price of common shares;
• | fluctuations in the interest rate paid for the use of the credit facility;
• | increased operating costs, which may reduce the fund's total return;
• | the potential for a decline in the value of an investment acquired through leverage, while the fund's obligations under such leverage remains fixed; and
• | the fund is more likely to have to sell securities in a volatile market in order to meet asset coverage or other debt compliance requirements.

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, conversely, returns would be lower if the cost of the leverage exceeds the income or capital appreciation derived.

In addition to the risks created by the fund's use of leverage, the fund is subject to the risk that it would be unable to timely, or at all, obtain replacement financing if the LA is terminated. Were this to happen, the fund would be required to de-leverage, selling securities at a potentially inopportune time and incurring tax consequences. Further, the fund's ability to generate income from the use of leverage would be adversely affected.

Note 8 — Liquidity agreement

Effective December 2, 2015, the fund has entered into the LA with State Street Bank & Trust Company (SSB) that allows it to borrow up to $428 million (maximum facility amount) and includes a securities lending provision. The amounts outstanding at April 30, 2016 are shown in the Statement of assets and liabilities as LA payable.

The fund pledges its assets as collateral to secure obligations under the LA. The fund retains the risks and rewards of the ownership of assets pledged to secure obligations under the LA and may make these assets available for securities lending transactions. Under the terms of the LA, the fund may enter into securities lending transactions initiated by SSB, acting as the fund's authorized securities lending agent. All securities lent through SSB are required to be secured with cash collateral received from the securities lending counterparty in amounts at least equal to 100% of the initial market value of the securities lent. Cash collateral received by SSB, in its role as securities lending agent for the fund is credited against the amounts drawn under the LA. Any amounts credited against the LA are considered leverage and would be subject to various limitations in the LA and/or the 1940 Act. Upon return of loaned securities, SSB will return collateral to the securities lending counterparty and will cause amounts drawn under the LA to increase by the amount of collateral returned. Amounts paid by securities lending counterparties for loaned securities are retained by SSB.

In the event of a securities lending counterparty default, SSB indemnifies the fund for certain losses that may arise in connection with the default. SSB uses the collateral received from the securities lending counterparty to purchase replacement securities of the same issue, type, class and series of the loaned securities. If the value of the collateral is less than the purchase cost of the replacement securities, SSB is responsible for satisfying the shortfall but only to the extent that the shortfall is not due to any decrease in the value of the collateral. Although the risk of the loss of the securities lent is mitigated by receiving collateral from the securities lending counterparty and through SSB indemnification, the fund could experience a delay in recovering securities or could experience a lower than expected return if the securities lending counterparty fails to return the securities on a timely basis.

Interest charged is at the rate of one-month LIBOR (London Interbank Offered Rate) plus 0.625%, and is payable monthly on the collective balance of the drawdowns outstanding and the securities lending activities of the fund. As of April 30, 2016,

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 25

the fund had a collective balance of $427,900,000 at an interest rate of 1.06%, which is reflected in the LA payable on the Statement of assets and liabilities. During the period from December 2, 2015 to April 30, 2016, the average balance of the LA and the effective average interest rate were $426,601,987 and 1.06%, respectively.

After the six month anniversary of the effective date of the agreement, the fund may terminate the LA with 60 days' notice. If certain asset coverage and collateral requirements, minimum net assets or other covenants are not met, the LA could be deemed in default and result in termination. Absent a default or facility termination event, SSB is required to provide the fund with 360 days' notice prior to terminating the LA.

Prior to December 2, 2015, the fund had entered into a credit facility agreement (CFA) with Credit Suisse Securities (USA) LLC (CSSU), that allowed the fund's borrowings not to exceed 331\3% of the fund's managed assets and to invest the borrowings in accordance with its investment practices. Interest was charged at the rate of one-month LIBOR plus 0.72% and was paid monthly. During the period from November 1, 2015 to December 1, 2015, the average balance of the CFA and the effective average interest rate were $426,319,355 and 0.92%, respectively. The combined interest accrued by the fund for both the LA and the CFA, for the six months ended April 30, 2016, is reflected in the Interest expense on the Statement of operations. The blended effective average interest rate for the six months ended April 30, 2016 was 1.04%.

Note 9 — Purchase and sale of securities

Purchases and sales of securities, other than short-term investments, amounted to $78,503,762 and $83,354,508, respectively, for the six months ended April 30, 2016.

Note 10 — Industry or sector risk

The fund generally invests a large percentage of its assets in one or more particular industries or sectors of the economy. If a large percentage of the fund's assets are economically tied to a single or small number of industries or sectors of the economy, the fund will be less diversified than a more broadly diversified fund, and it may cause the fund to underperform if that industry or sector underperforms. In addition, focusing on a particular industry or sector may make the fund's NAV more volatile. Further, a fund that invests in particular industries or sectors is particularly susceptible to the impact of market, economic, regulatory and other factors affecting those industries or sectors.

Investment objective and policy

The fund is a closed-end, diversified management investment company, common shares of which were initially offered to the public on February 25, 2004, and are publicly traded on the New York Stock Exchange (the NYSE). The fund's investment objective is to provide a high level of after-tax total return from dividend income and gains and capital appreciation. The fund utilizes a credit facility agreement to increase its assets available for investments.

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 subadvisors believe 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 are currently taxed to noncorporate taxpayers at a maximum rate of 20% (15% or 0% for individuals in certain tax brackets) (tax-advantaged dividends). The fund will notify shareholders at least 60 days prior to any change in this 80% investment policy. 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. The fund may write (sell) covered call index options on up to 30% of the value of the fund's total assets.

Effective December 2, 2015, the Board of Trustees approved changes to the fund's investment policy regarding securities lending, replacing it with the following: "The fund may seek to obtain additional income or portfolio leverage by making secured loans of its portfolio securities with a value of up to 33 1/3% of its total assets. In such transactions, the borrower pays to the fund an amount equal to any dividends or interest received on loaned securities. The fund retains all or a portion of the dividends, interest, capital gains, and/or other distributions received on investment of cash collateral in short-term obligations of the U.S. government, cash equivalents (including shares of a fund managed by the fund's investment adviser or an affiliate thereof), or other investments consistent with the fund's investment objective, policies, and restrictions, or receives a fee from the borrower. As a result of investing such cash collateral in such investments, the fund will receive the benefit of any gains and bear any losses generated by such investments. All securities loans will be made pursuant to agreements requiring that the loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the market value of the loaned securities. The fund may pay reasonable finders', administrative and custodial fees in connection with loans of its portfolio securities. Although voting rights or rights to consent accompanying loaned securities pass to the borrower, the fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the fund with respect to matters materially affecting the fund's investment. The fund may also call a loan in order to sell the securities involved. Lending portfolio securities involves risks of delay in recovery of the loaned securities or, in some cases, loss of rights in the collateral should the borrower commence an action relating to bankruptcy, insolvency or reorganization. Accordingly, loans of portfolio securities will be made only to borrowers considered by the Adviser to be creditworthy under guidelines adopted by the Board of Trustees. Investing cash collateral received in connection with securities lending transactions in any investment that is consistent with the fund's investment objective, policies, and limitations may subject the fund to risk of loss greater than the risk of loss associated with investing collateral solely in short-term U.S. government obligations or cash equivalents."

The use of securities lending collateral to obtain leverage in the fund's investment portfolio may subject the fund to greater risk of loss than would reinvestment of collateral in short-term, highly-rated investments. Risks associated with the fund's use of leverage are discussed under Note 7 to the financial statements.

Declaration of Trust

Effective January 22, 2016, the Board of Trustees of the fund amended and restated in its entirety the Agreement and Declaration of Trust of the fund (the "Declaration of Trust"). The amendments to the Declaration of Trust include, among other changes, provisions that: (i) clarify certain duties, responsibilities, and powers of the Trustees; (ii) clarify that, other than as provided under federal securities laws, the shareholders may only bring actions involving the Trust derivatively; (iii) provide that any action brought by a shareholder related to the Trust will be brought in Massachusetts state or federal court, and that, if a claim is brought in a different jurisdiction and subsequently changed to a Massachusetts venue, the shareholder will

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 27

be required to reimburse the Trust for expenses related to changing venue; and (iv) clarify that shareholders are not intended to be third-party beneficiaries of fund contracts. The foregoing description of the Declaration of Trust is qualified in its entirety by the full text of the Declaration of Trust, effective as of January 22, 2016, which is available by writing to the Secretary of the fund at 601 Congress Street, 11th Floor, Boston, Massachusetts 02210.

By-Laws
