Tax-Advantaged Dividend Income Fund

Semiannual report 4/30/17

Managed distribution plan

On September 19, 2016, the fund adopted a managed distribution plan (Plan). Under the Plan, the fund makes monthly distributions of an amount equal to $0.1380 per share, which will be paid monthly until further notice. The fund may make additional distributions (i) for purposes of not incurring federal income tax on investment company taxable income and net capital gain, if any, not included in such regular distributions and (ii) for purposes of not incurring federal excise tax on ordinary income and capital gain net income, if any, not included in such regular monthly distributions.

The Plan provides that the Board of Trustees of the fund may amend the terms of the Plan or terminate the Plan at any time without prior notice to the fund's shareholders. The Plan is subject to periodic review by the fund's Board of Trustees.

You should not draw any conclusions about the fund's investment performance from the amount of the fund's distributions or from the terms of the Plan. The fund's total return at NAV is presented in the Financial Highlights.

With each distribution that does not consist solely of net investment income, the fund will issue a notice to shareholders and an accompanying press release that will provide detailed information regarding the amount and composition of the distribution and other related information. The amounts and sources of distributions reported in the notice to shareholders are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the fund's investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes. The fund may at times distribute more than its net investment income and net realized capital gains; therefore, a portion of your distribution may result in a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the fund is paid back to you. A return of capital does not necessarily reflect the fund's investment performance and should not be confused with "yield" or "income."

A message to shareholders

Dear shareholder,

U.S. stocks and the credit segments of the bond market rallied sharply over the past six months, with several indexes reaching all-time highs before pulling back in the first half of April. In some ways, this recent pause wasn't surprising: Much of the fuel for the rally had been investor optimism over the Trump administration's ability to implement pro-growth policies that would boost economic expansion. Instead, the new administration has struggled with a series of controversies, and investors seem to be waiting for policy to catch up with expectations before bidding asset prices up further.

Regardless of what happens in Washington, asset prices in the United States enjoy the support of solid economic growth, low inflation, and rising levels of employment. Potential headwinds include high valuations—particularly when compared with foreign stocks—and any sustained increase in political uncertainty. Just as John Hancock Investments regularly monitors the risks taken by the portfolio teams managing our funds, it is prudent to periodically check in with your financial advisor to ensure 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

Your fund at a glance

INVESTMENT OBJECTIVE

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

AVERAGE ANNUAL TOTAL RETURNS AS OF 4/30/17 (%)

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 performance at net asset value (NAV) is different from the fund's performance at closing market price because the closing market price is subject to the dynamics of secondary market trading. 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.

The performance data contained within this material represents past performance, which does not guarantee future results.

PERFORMANCE HIGHLIGHTS OVER THE LAST SIX MONTHS

Income-producing investments posted modest gains

Late 2016 losses were offset by better performance in the first four months of 2017.

Utility common stock holdings were some of the fund's best performers

Common stock holdings CenterPoint Energy, Inc., Vectren Corp., and DTE Energy Co. fared well amid strong financial results.

Detractors included companies from healthcare and energy sectors

Healthcare firm Teva Pharmaceutical Industries, Ltd. was a key detractor, along with energy companies Royal Dutch Shell plc and BP plc.

PORTFOLIO COMPOSITION AS OF 4/30/17 (%)

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—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

Can you tell us about recent and upcoming changes to fund management?

Effective February 15, 2017, Brad Lutz, CFA, joined our team. He has more than 20 years of investment experience. Effective August 31, 2017, I will be retiring. Brad Lutz, Joseph Bozoyan, CFA, and the team at Analytic Investors will continue to manage the fund.

What was the market environment like for income-producing securities during the six months ended April 30, 2017?

Income-producing investments—including the preferred securities and utility common stocks that are the main areas of emphasis for the fund—posted modestly positive returns, with solid gains so far in 2017 offsetting losses in the final two months of 2016. In late 2016, income-producing securities were under pressure amid the surprise election of President Donald Trump, which, in conjunction with strong third quarter U.S. economic data, ratcheted up expectations for higher inflation and higher interest rates. Year-end tax-loss selling—which investors used to offset investment losses against gains—put additional pressure on income-producing assets.

But during the first four months of 2017, preferred securities, utility common stocks, and other income-producers fared better. U.S. Treasury yields moved sideways and remained low relative to history, despite the U.S. Federal Reserve's (Fed's) quarter-point rate hikes in December and March. Low and range-bound U.S. Treasury yields provided a neutral rate backdrop for income-producing asset classes. Preferred securities were also bolstered by favorable supply-and-demand dynamics. There was scant issuance of preferreds during the first quarter of 2017, reducing already tight supply as companies seemed reticent to issue new preferreds in advance of potential Trump administration corporate tax changes.

What's your view on income-producing investments?

We continue to foresee favorable conditions for income-producing investments over the next several months. Interest rates may continue to move gradually higher, but will remain low relative to historical measures, given our view that global growth will remain tepid. Although some aspects of the Trump growth agenda may be implemented in 2017, others may not be enacted or felt until

2018 and beyond. Additionally, we believe the Fed will remain cautious and gradual in its bid to normalize monetary policy, especially given the prospects that higher rates could slow the U.S. economy.

Yields on European government debt remain low, suggesting that the world economic recovery may still be vulnerable. We doubt the Fed will risk upsetting already fragile economic conditions abroad. It appears to us that corporations remain reluctant to issue new preferreds until they have more clarity on potential Trump-led corporate tax rate reductions. But we believe demand for preferred securities and utility common stocks could remain solid over the near term, as we expect investors' search for yield to continue until the economy exhibits demonstrable and sustainable strength.

Additionally, the aging global population should foster ongoing demand for preferred securities and utility common stocks as older investors migrate larger portions of their portfolios into income-producing investments.

What holdings contributed to performance?

Although the vast majority of the fund's income-producing investments produced gains during the six-month period, some holdings—led by investments in utility common stocks—were standouts. CenterPoint Energy, Inc. performed quite well, bolstered by investor enthusiasm for the company's strong financial results and good earnings outlook, as well as its decision to increase dividend payments to shareholders. Vectren Corp. was another top performer for the fund, boosted in part by

strong fundamental growth, as well as investor speculation that it could be a merger-or-acquisition target. DTE Energy Co. performed well, helped in part by strength in its midstream gas operations.

Among our preferred securities holdings, Great Plains Energy Inc. was one of our best performers. Holdings in this utility company were helped largely by strong investor demand for securities with attractive coupons, as well as the company's improved underlying fundamentals.

Among financial preferreds, we saw good results with Morgan Stanley and State Street Corp. The combination of the companies' strong fundamental growth, the securities' high coupons and good call protection, and the dearth of supply of high-quality preferreds helped boost the prices of these holdings.

What holdings hurt the fund's performance?

Teva Pharmaceutical Industries, Ltd., the world's largest maker of generic drugs, suffered price declines. Political scrutiny of the drug industry, as epitomized by comments from President Trump that strongly suggested he felt drug prices were too high, weighed on Teva, as did unfilled executive management positions at the company.

Energy-related common stock holdings, including Royal Dutch Shell plc and BP plc, detracted from

performance as the recovery in oil prices lost steam. The fund's option strategy, which focused primarily on S&P 500 Index contracts, was also a detractor.

Were there any significant changes to the portfolio?

Early in the period, some of the fund's Morgan Stanley and Entergy Corp. preferred issues were called. We were able to replace these with comparable yielding, newly issued convertible preferred securities from utility companies that need to finance acquisitions, including Dominion Resources, Inc. and Great Plains Energy. Toward the end of 2016, we used the proceeds from some preferred securities call outs to buy other preferreds that we felt were attractively valued after having been unduly punished by the broad sell-off of income-producing investments.

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.

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 trades. 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 trades. Swaps and unlisted options 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.

Securities with a market value of approximately $10,300,000 at the beginning of the year were transferred from Level 2 to 1 during the period since quoted prices in active markets for identical securities became available.

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 20

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.

As of October 31, 2016, 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.

Managed distribution plan. On September 19, 2016, the fund adopted a managed distribution plan (Plan). Under the Plan, the fund makes monthly distributions of an amount equal to $0.1380 per share, an increase over the previous monthly distribution of $0.1210 per share, which will be paid monthly until further notice.

Distributions under the Plan may consist of net investment income, net realized long-term capital gains, net realized short term capital gains and, to the extent necessary, return of capital. Return of capital distributions may be necessary when the fund's net investment income and net capital gains are insufficient to meet the minimum distribution. In addition, the fund may also make additional distributions for the purpose of not incurring federal income and excise taxes.

The Board of Trustees may terminate or reduce the amount paid under the Plan at any time. The termination or reduction may have an adverse effect on the market price of the fund's shares.

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 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 or cash held at broker for futures contracts.

Note 3 — Derivative Instruments

The fund may invest in derivatives in order to meet its investment objective. Derivatives include a variety of different instruments that may be traded in the over-the-counter (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,

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 21

the liquidity or 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.

Futures are traded or cleared on an exchange. Exchange-traded 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 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, 2017, the fund used futures contracts to manage against anticipated interest rate changes. The fund held futures contracts with notional values ranging up to $123.2 million, as measured at each quarter end.

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

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

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, 2017, the fund wrote option contracts to hedge against anticipated changes in securities markets and to generate potential income. The following table summarizes the fund's written options activities during the six months ended April 30, 2017:

|  |  |  | Number of contracts |  |  | Premiums received |
| Outstanding, beginning of period |  |  | 1,115 |  |  | $2,014,014 |
| Options written |  |  | 2,651 |  |  | 3,955,703 |
| Option closed |  |  | (1,839 | ) |  | (3,688,215 | )
| Options exercised |  |  | — |  |  | — |
| Options expired |  |  | (1,349 | ) |  | (1,327,983 | )
| Outstanding, end of period |  |  | 578 |  |  | $953,519 |

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 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, 2017, the fund used interest rate swaps to manage against anticipated interest rate changes. The fund held interest rate swaps with total USD notional amounts ranging from $82.0 million to $86.0 million, as measured at each quarter end.

Fair value of derivative instruments by risk category

The table below summarizes the fair value of derivatives held by the fund at April 30, 2017 by risk category:

| Risk |  |  | Statement of assets and liabilities location |  |  |  |  |  | Financial instruments location |  |  | Assets derivatives fair value |  |  | Liabilities derivative fair value |
| Interest rate |  |  | Receivable/payable for futures |  |  |  |  |  | Futures† |  |  | — |  |  | ($197,411 | )
| Equity |  |  | Written options, at value |  |  |  |  |  | Written options |  |  | — |  |  | (1,465,065 | )
| Interest rate |  |  | Swap contracts, at value |  |  |  |  |  | Interest rate swaps |  |  | — |  |  | (122,770 | )
| † Reflects cumulative appreciation/depreciation on futures as disclosed in Note 3. Only the period end variation margin is separately disclosed on the Statement of assets and liabilities. |

For financial reporting purposes, the fund does not offset OTC derivative assets or liabilities that are subject to master netting arrangements, as defined by the ISDAs, in the Statement of assets and liabilities. In the event of default by the counterparty or a termination of the agreement, the ISDA allows an offset of amounts across the various transactions between the fund and the applicable counterparty.

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) (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, 2017, 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 $50,466 for the six months ended April 30, 2017.

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, 2017 were equivalent to a net annual effective rate of 0.74% of the fund's average daily managed assets.

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

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, 2017 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 is 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, 2016. The current share repurchase plan will remain in effect between January 1, 2017 and December 31, 2017.

During the six months ended April 30, 2017, the fund had no repurchased activities under repurchase program. For the year ended October 31, 2016, the fund repurchased 0.91% of its common shares outstanding under the repurchase program. The weighted average discount per share on these repurchases amount to 11.56% for the year ended October 31, 2016. 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 a Liquidity Agreement to increase its assets available for investment. When the fund leverages its assets, common shareholders bear the fees associated with the Liquidity Agreement 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 Liquidity Agreement;
• | 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. The use of securities lending to obtain leverage in the fund's investments may subject the fund to greater risk of loss than would reinvestment of collateral in short-term highly rated investments.

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 Liquidity Agreement 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.

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

Note 8 — Liquidity agreement

The fund has entered into a Liquidity Agreement (LA) with State Street Bank and Trust Company (SSB) that allows it to borrow or otherwise access up to $428 million (maximum facility amount) through a line of credit, securities lending and reverse repurchase agreements. The amounts outstanding at April 30, 2017 are shown in the Statement of assets and liabilities as the Liquidity agreement.

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 makes these assets available for securities lending and reverse repurchase transactions with SSB acting as the fund's authorized agent for these transactions. All transactions initiated through SSB are required to be secured with cash collateral received from the securities borrower (the Borrower) or cash is received from the reverse repurchase agreement (Reverse Repo) counterparties. Securities lending transactions will be secured with cash collateral in amounts at least equal to 100% of the market value of the securities utilized in these transactions. Cash received by SSB from securities lending or Reverse Repo transactions is credited against the amounts borrowed under the line of credit.

Upon return of securities by the Borrower or Reverse Repo counterparty, SSB will return the cash collateral to the Borrower or proceeds from the Reverse Repo, as applicable, which will eliminate the credit against the line of credit and will cause the drawdowns under the line of credit to increase by the amounts returned. Income earned on the loaned securities is retained by SSB, and any interest due on the reverse repurchase agreements is paid by SSB.

SSB has indemnified the fund for certain losses that may arise if the Borrower or a Reverse Repo Counterparty fails to return securities when due. With respect to securities lending transactions, upon a default of the securities borrower, SSB uses the collateral received from the Borrower to purchase replacement securities of the same issue, type, class and series. If the value of the collateral is less than the purchase cost of replacement securities, SSB is responsible for satisfying the shortfall but only to the extent that the shortfall is not due to any of the fund's losses on the reinvested cash collateral. Although the risk of the loss of the securities is mitigated by receiving collateral from the Borrower or proceeds from the Reverse Repo counterparty and through SSB indemnification, the fund could experience a delay in recovering securities or could experience a lower than expected return if the Borrower or Reverse Repo counterparty fails to return the securities on a timely basis.

Under normal circumstances, interest charged is at the rate of one month LIBOR (London Interbank Offered Rate) plus 0.625%, is payable monthly on the aggregate balance of the drawdowns outstanding under the LA. As of April 30, 2017, the fund had an aggregate balance of $427,900,000 at an interest rate of 1.62%, which is reflected in the Liquidity agreement on the Statement of assets and liabilities. During the six months ended April 30, 2017, the average balance of the LA and the effective average interest rate were $427,900,000 and 1.44%, 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, 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.

Note 9 — Purchase and sale of securities

Purchases and sales of securities, other than short-term investments, amounted to $46,313,930 and $46,704,852, respectively, for the six months ended April 30, 2017.

Note 10 — Industry or sector risk

The fund may invest 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.

SEMIANNUAL REPORT | JOHN HANCOCK TAX-ADVANTAGED DIVIDEND INCOME FUND 26

Note 11 — New rule issuance

In October 2016, the SEC issued Final Rule Release No.33-10231, Investment Company Reporting Modernization (the Release). The Release calls for the adoption of new rules and forms as well as amendments to its rules and forms to modernize the reporting and disclosure of information by registered investment companies. The SEC is adopting amendments to Regulation S-X, which will require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The updates to Regulation S-X are effective August 1, 2017 and may result in additional disclosure relating to the presentation of derivatives and certain other financial instruments. These updates will have no impact on the fund's net assets or results of operations.

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 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.

Dividends and distributions

During the six months ended April 30, 2017, distributions from net investment income totaling $0.8280 per share and distributions from capital gains totaling $0.1639 per share were paid to shareholders. The dates of payments and the amounts per share were as follows:
