President's Letter

Dear Shareowner,

While investors were greeted with a challenging market environment for the first
several weeks of the new year, the U.S. market generated modest single-digit
returns for both stocks and bonds through September 30th (the Bloomberg Barclays
Aggregate Bond Index was up by 5.8% through September 30, 2016, and the Standard
& Poor's 500 Index was up by 7.8%). Yet, it is becoming increasingly clear that
the investment landscape is undergoing significant change. For the past eight
years, global central banks have been the dominant force in the markets by
maintaining government bond yields at close to zero in an effort to stimulate
economic growth. With little room to lower rates further, however, central banks
may be losing their effectiveness. Many economies around the world are
experiencing slow growth as they face a variety of challenges, including the
shifting geopolitics driving "Brexit" - the United Kingdom's pending exit from
the European Union - as well as related movements in Europe, limited
productivity gains, aging populations, and transitioning economic models in
China and other emerging markets. In the United States, gross domestic product
(GDP) grew at a rate of approximately 1.2% in the first half of 2016, but GDP
growth registered a strong uptick in the third quarter of the year, driven
primarily by U.S. consumers.

Investors currently face a difficult environment. Government bond yields, as
noted earlier, had been near zero for most of the year and offered minimal
opportunity to produce income. However, recent developments such as the Federal
Reserve's decision to increase the Federal funds rate before the end of 2016
have driven yields slightly higher. The central bank-driven bull market in
riskier assets has pushed up valuations towards historic highs in the equity and
investment-grade and high-yield corporate bond markets. Central banks have
pledged to move gradually to normalize interest-rate policies as the global
economy recovers, but it will take many years for this historic credit cycle to
unwind. Politics may also influence markets or investor sentiment given the
current global political landscape. Donald Trump's surprising victory in the
November U.S. presidential election seems to have sparked a late-year market
rally, given the pro-growth proposals he promoted on the campaign trail, but it
is unclear just how many of his policy initiatives will be implemented. In
addition, continued challenges with Brexit and other geopolitical issues have
the potential to increase market volatility going forward. Against this
backdrop, investors are likely to face ongoing challenges when it comes to
finding opportunities for both income and capital appreciation, and while much
has been made of passive investing, we believe all investment decisions are
active choices.

Portfolio Management Discussion | 10/31/16

In the following interview, John Carey, Executive Vice President and a portfolio
manager at Pioneer Investments, discusses the investment environment during the
12-month period ended October 31, 2016, and Pioneer Equity Income Fund's
performance during the period. Mr. Carey is responsible for the day-to-day
management of Pioneer Equity Income Fund, along with Walter Hunnewell, Jr., a
vice president and a portfolio manager at Pioneer.

Q    How did the Fund perform during the 12-month period ended October 31, 2016?

A    Pioneer Equity Income Fund's Class A shares returned 8.11% at net asset
     value during the 12-month period ended October 31, 2016, while the Fund's
     benchmark, the Russell 1000 Value Index, returned 6.37%. During the same
     period, the average return of the 508 mutual funds in Lipper's Equity
     Income Funds category was 4.70%, and the average return of the 1,371 mutual
     funds in Morningstar's Large Value Funds category was 3.72%.

Q    How would you describe the market environment for equities during the
     12-month period ended October 31, 2016, particularly for the types of
     equities deemed appropriate for the Fund?

A    The first three-and-a-half months of the period saw the stock market
     decline in the United States. A rate increase by the Federal Reserve (the
     Fed) in December 2015, together with lackluster and even declining
     corporate earnings, slumping oil prices, and geopolitical tensions, caused
     concern among investors. Then, in the middle of February 2016, began a
     recovery that, on the whole, continued through period end. Explanations for
     the change in market direction ranged from decreasing concern that the Fed
     would push rates up too quickly, to recovering commodities prices, to
     expectations for stronger economic activity in the second half of calendar
     year 2016. The economic optimism led investors to bid up the prices of more
     cyclical, value stocks, and the Russell 1000 Value Index (the Russell
     Index), the Fund's benchmark, outperformed the Russell 1000 Growth Index
     for the full 12-month period. It was a generally good period particularly
     for the dividend-paying*, value stocks we typically hold in Pioneer Equity
     Income Fund, as the unsettled state of the markets in the earlier months of
     the period appeared to incline investors towards stocks with income
     support.

*    Dividends are not guaranteed.

4 Pioneer Equity Income Fund | Annual Report | 10/31/16


Q    The Fund outperformed the Russell Index benchmark during the 12-month
     period ended October 31, 2016. Could you please discuss the major reasons
     for the Fund's benchmark-relative outperformance, and discuss any
     investments or strategies that detracted from benchmark-relative returns?

A    The Fund's benchmark-relative performance benefited from both sector
     allocation and security selection decisions during the 12-month period. The
     portfolio was overweight the top-performing utilities sector and had above-
     average stock performance in that sector. Three of the Fund's utility
     holdings, Empire District Electric, Questar, and Westar, received premium
     acquisition offers during the period, thus benefiting performance. Another
     utility name in the portfolio, Alliant Energy, showed a total return of 33%
     over the 12 months. The portfolio also had above-index weights to the
     strong-performing consumer-staples and materials sectors, and below-index
     weights to the weaker performing energy and financials sectors. While the
     Fund's benchmark-relative performance was negatively affected by an
     underweight to the strong-performing information-technology sector, making
     up for that, and then some, was the exceptionally positive share-price
     performance from portfolio holdings in technology stocks NVIDIA, Microchip
     Technology, and Linear Technology, the last of which received a premium
     take-over offer from another semiconductor company. A couple of other Fund
     holdings that received purchase offers, Valspar (materials) and G&K
     Services (industrials), likewise contributed importantly to
     benchmark-relative results.

     On the negative side, the Fund was slightly underweight the strong-
     performing industrials sector during the period, and, to boot, one of the
     portfolio's larger holdings in the sector, Gorman-Rupp, actually declined
     by 15% on a total-return basis over the period as orders for the company's
     waste-water, agricultural, and oil-service pumps fell. We have, however,
     retained the shares, since we believe that pump orders will recover. In
     consumer staples, stock selection results detracted from the Fund's
     benchmark-relative performance, as we were late in buying shares of the
     surging Wal-Mart Stores, and we did not own any shares of resurgent Procter
     & Gamble. The Fund's relative returns suffered from unfavorable stock
     selection in the energy sector as well, as the names the portfolio owned
     did not show the sharp recovery that other energy stocks did when the oil
     market turned positive in the spring.

Q    Please discuss changes to the portfolio during the 12-month period ended
     October 31, 2016.

A    As the Fed began to show resolve regarding increasing interest rates, a
     potentially favorable development for many financial-services companies, we
     gradually boosted the Fund's exposure to the financials sector. In the

                         Pioneer Equity Income Fund | Annual Report | 10/31/16 5


     first six months of the period we added, for example, positions in PNC
     Financial (banking) and Sun Life Financial (insurance and money
     management); and, in the second six months we established positions in
     Invesco (money management) and Discover Financial Services (consumer
     credit), while re-establishing positions in former portfolio companies
     JPMorgan Chase and US Bancorp. Kroger and Wal-Mart Stores were new entries
     for the portfolio in consumer staples. Both are large food retailers, while
     Wal-Mart, of course, also sells general merchandise. In utilities, we added
     WEC Energy, which appears to us a very well-managed public utility in the
     upper Middle West. In information technology, we added Xilinx, which
     designs, for specialized technological applications, what are called
     "programmable microchips."

     Throughout the 12-month period we built positions in metals-and-mining
     stocks, including Kaiser Aluminum, Nucor, Materion, Southern Copper, Rio
     Tinto, and BHP Billiton, as we judged that investors had become too
     pessimistic about the prospects for what have been, after all, basic
     materials for industrial production for thousands of years.

     Regarding sales from the portfolio during the period, we did take profits
     on most of the stocks that received take-over offers, including the three
     aforementioned utilities as well as Valspar, G&K Services, Linear
     Technology, BioMed Realty Trust, and Agrium. Otherwise, as always, we sold
     a number of stocks that we believed had reached fair value or that no
     longer appeared as attractive to us from an investment point of view as
     other stocks in the portfolio. Liquidated positions in those categories
     included shares of NextEra Energy, Dow Chemical, Electrolux, Intel, Amgen,
     Citizens Financial Group, and Progressive, among a number of others.

Q    Did the Fund hold any derivatives during the 12-month period ended October
     31, 2016?

A    No, the Fund held no derivative positions during the period.

Q    The Fund typically places an emphasis on dividend-paying stocks. Was the
     setting for such stocks good or poor during the 12-month period ended
     October 31, 2016?

A    For the period as a whole, dividend-paying stocks were favored by investors
     rattled by market volatility and desirous of income in a low-interest-rate
     environment. However, utilities stocks as well as some consumer-staples
     stocks, both prized for their steady dividends, came off their highs for a
     time during the second half of the period as investors anticipated higher
     interest rates and looked again at growth, as opposed to value, stocks. We
     think that key, along with rising rates, will be emphasizing companies with

6 Pioneer Equity Income Fund | Annual Report | 10/31/16


     the ability and commitment to raise their dividends regularly. It will be
     that combination of growth and value that will hold up better, we think, if
     interest rates rise.

Q    What is your outlook as we head towards a new calendar year, and a new
     political administration in Washington, D.C.?

A    The victory of the Republicans in the November elections was more sweeping
     than many pollsters and pundits had thought likely. The Republicans won not
     only the Presidency, but also many governorships and state legislatures,
     while retaining control of both the U.S. House of Representatives and the
     U.S. Senate, even though the Democrats did pick-up a few seats. We think it
     possible, as a result, that there will be more changes in policies and
     programs than we might have seen in the event of a more mixed result with
     the attendant "gridlock." We believe it reasonable to assume, then, in
     particular, that some trade agreements will be renegotiated and some tax
     and regulatory policies will be revised. So far, the stock market appears
     expectant of change that will be positive for economic growth, and growth
     that is faster than what we have seen over the past several years. At
     Pioneer we always take the approach of watching and waiting on actual
     events. We shall follow keenly what happens in Washington as well as at the
     state level. In the end, though, we believe that companies, their
     managements and workers create economic growth and true value for
     shareholders, and our main focus will remain on that "micro" world.

     Thank you as always for your support.

The Russell 1000 Value Index is an unmanaged index that measures the performance
of large-cap U.S. value stocks. Index returns are calculated monthly, assume
reinvestment of dividends and, unlike Fund returns, do not reflect any fees,
expenses or sales charges. It is not possible to invest directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-15.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

The performance shown for Class K shares for the period prior to the
commencement of operations of Class K shares on December 20, 2012, is the net
asset value performance of the Fund's Class A shares, which has not been
restated to reflect any differences in expenses, including Rule 12b-1 fees
applicable to Class A shares. Since fees for Class A shares generally are higher
than those of Class K shares, the performance of Class K shares prior to their
inception on December 20, 2012, would have been higher than the performance
shown. For the period beginning December 20, 2012, the actual performance of
Class K shares is reflected. Class K shares are not subject to sales charges and
are available for limited groups of eligible investors, including institutional
investors. All results are historical and assume the reinvestment of dividends
and capital gains.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Fund expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1)  Divide your account value by $1,000
     Example: an $8,600 account value (divided by) $1,000 = 8.6

(2)  Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

     1.77%, 0.67% 1.40% and 0.77% for Class A, Class C, Class K, Class R and
     Class Y shares, respectively, multiplied by the average account value over
     the period, multiplied by 184/366 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Notes to Financial Statements | 10/31/16

1. Organization and Significant Accounting Policies

Pioneer Equity Income Fund (the Fund) is a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is current
income and long-term growth of capital from a portfolio consisting primarily of
income producing equity securities of U.S. corporations.

The Fund offers five classes of shares designated as Class A, Class C, Class K,
Class R and Class Y shares. Class B shares converted to Class A shares as of the
close of business on November 10, 2014. Class Z shares were converted to Class Y
shares as of the close of business on August 7, 2015. Each class of shares
represents an interest in the same portfolio of investments of the Fund and has
identical rights (based on relative net asset values) to assets and liquidation
proceeds. Share classes can bear different rates of class-specific fees and
expenses such as transfer agent and distribution fees. Differences in class-
specific fees and expenses will result in differences in net investment income
and, therefore, the payment of different dividends from net investment income
earned by each class. The Amended and Restated Declaration of Trust of the Fund
gives the Board of Trustees the flexibility to specify either per-share voting
or dollar-weighted voting when submitting matters for shareholder approval.
Under per-share voting, each share of a class of the Fund is entitled to one
vote. Under dollar-weighted voting, a shareholder's voting power is determined
not by the number of shares owned, but by the dollar value of the shares on the
record date. Each share class has exclusive voting rights with respect to
matters affecting only that class, including with respect to the distribution
plan for that class. There is no distribution plan for Class K or Class Y
shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles (U.S. GAAP) that require the management
of the Fund to make estimates and assumptions that affect the reported amounts
of assets and liabilities, the disclosure of contingent assets and liabilities
at the date of the financial statements, and the reported amounts of income,
expenses and gains and losses on investments during the reporting period. Actual
results could differ from those estimates.

The Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. The following is a summary of significant
accounting policies followed by the Fund in the preparation of its financial
statements:

34 Pioneer Equity Income Fund | Annual Report | 10/31/16


A.   Security Valuation

     The net asset value of the Fund is computed once daily, on each day the New
     York Stock Exchange (NYSE) is open, as of the close of regular trading on
     the NYSE.

     Equity securities that have traded on an exchange are valued by using the
     last sale price on the principal exchange where they are traded. Equity
     securities that have not traded on the date of valuation, or securities for
     which sale prices are not available, generally are valued using the mean
     between the last bid and asked prices or, if both last bid and asked prices
     are not available, at the last quoted bid price. Last sale and bid and
     asked prices are provided by independent third party pricing services. In
     the case of equity securities not traded on an exchange, prices are
     typically determined by independent third party pricing services using a
     variety of techniques and methods.

     The value of foreign securities is translated into U.S. dollars based on
     foreign currency exchange rate quotations supplied by a third party pricing
     source. Trading in non-U.S. equity securities is substantially completed
     each day at various times prior to the close of the NYSE. The values of
     such securities used in computing the net asset value of the Fund's shares
     are determined as of such times. The fund may use a fair value model
     developed by an independent pricing service to value non-U.S. equity
     securities.

     Securities for which independent pricing services or broker-dealers are
     unable to supply prices or for which market prices and/or quotations are
     not readily available or are considered to be unreliable are valued by a
     fair valuation team comprised of certain personnel of Pioneer Investment
     Management, Inc. (PIM), the Fund's investment adviser and a wholly owned
     indirect subsidiary of UniCredit S.p.A. (UniCredit), pursuant to procedures
     adopted by the Fund's Board of Trustees. PIM's fair valuation team uses
     fair value methods approved by the Valuation Committee of the Board of
     Trustees. PIM's fair valuation team is responsible for monitoring
     developments that may impact fair valued securities and for discussing and
     assessing fair values on an ongoing basis, and at least quarterly, with the
     Valuation Committee of the Board of Trustees.

     Inputs used when applying fair value methods to value a security may
     include credit ratings, the financial condition of the company, current
     market conditions and comparable securities. The Fund may use fair value
     methods if it is determined that a significant event has occurred after the
     close of the exchange or market on which the security trades and prior to
     the determination of the Fund's net asset value. Examples of a significant
     event might include political or economic news, corporate restructurings,
     natural

                        Pioneer Equity Income Fund | Annual Report | 10/31/16 35


     disasters, terrorist activity or trading halts. Thus, the valuation of the
     Fund's securities may differ significantly from exchange prices and such
     differences could be material.

     At October 31, 2016, there were no securities that were valued using fair
     value methods (other than securities valued using prices supplied by
     independent pricing services).

B.   Investment Income and Transactions

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in the exercise of reasonable diligence. Interest income, including
     interest on income bearing cash accounts, is recorded on the accrual basis.
     Dividend and interest income are reported net of unrecoverable foreign
     taxes withheld at the applicable country rates.

     Security transactions are recorded as of trade date. Gains and losses on
     sales of investments are calculated on the identified cost method for both
     financial reporting and federal income tax purposes.

C.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no federal income tax provision is required. As
     of October 31, 2016, the Fund did not accrue any interest or penalties with
     respect to uncertain tax positions, which, if applicable, would be recorded
     as an income tax expense in the Statement of Operations. Tax returns filed
     within the prior three years are subject to examination by Federal and
     State tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. GAAP. Distributions in excess of net investment
     income or net realized gains are temporary overdistributions for financial
     statement purposes resulting from differences in the recognition or
     classification of income or distributions for financial statement and tax
     purposes. Capital accounts within the financial statements are adjusted for
     permanent book/tax differences to reflect tax character, but are not
     adjusted for temporary differences.

     At October 31, 2016, the Fund reclassified $973,983 to decrease
     undistributed net investment income and $973,983 to increase accumulated
     net realized gain on investments and foreign currency transactions to
     reflect permanent book/tax differences. These adjustments have no impact on
     net assets or the results of operations.

36 Pioneer Equity Income Fund | Annual Report | 10/31/16


     The tax character of distributions paid during the fiscal years ended
     October 31, 2016 and October 31, 2015 were as follows:



     ------------------------------------------------------------------------
                                                    2016                 2015
     ------------------------------------------------------------------------
                                                          
     Distributions paid from:
     Ordinary income                       $  31,249,189        $  33,166,428
     Long-term capital gain                  110,276,877          128,314,155
     ------------------------------------------------------------------------
          Total                            $ 141,526,066        $ 161,480,583
     ========================================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2016:



     --------------------------------------------------------------------------
                                                                          2016
     --------------------------------------------------------------------------
                                                             
     Distributable earnings:
     Undistributed ordinary income                              $    1,870,936
     Undistributed long term capital gain                          186,881,606
     Net unrealized appreciation                                   293,153,586
     --------------------------------------------------------------------------
         Total                                                  $  481,906,128
     ==========================================================================


     The difference between book-basis and tax-basis net unrealized appreciation
     is attributable to the tax deferral of losses on wash sales and tax basis
     adjustments on REIT holdings, common stock holdings and partnerships.

D.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredit, earned $113,857
     in underwriting commissions on the sale of Class A shares during the year
     ended October 31, 2016.

E.   Class Allocations

     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on its respective percentage of adjusted net assets at the beginning
     of the day.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class C and Class R shares of the Fund,
     respectively (see Note 4). Class K and Class Y shares do not pay
     distribution fees. All expenses and fees paid to the Fund's transfer agent
     for its services are allocated among the classes of shares based on the
     number of accounts in each class and the ratable allocation of related
     out-of-pocket expenses (see Note 3).

                        Pioneer Equity Income Fund | Annual Report | 10/31/16 37


     Distributions to shareowners are recorded as of the ex-dividend date.
     Distributions paid by the Fund with respect to each class of shares are
     calculated in the same manner and at the same time, except that net
     investment income dividends to Class A, Class C, Class K, Class R and Class
     Y shares can reflect different transfer agent and distribution expense
     rates.

F.   Risks

     The value of securities held by the fund may go up or down, sometimes
     rapidly or unpredictably, due to general market conditions, such as real or
     perceived adverse economic, political or regulatory conditions, inflation,
     changes in interest rates, lack of liquidity in the bond markets or adverse
     investor sentiment. In the past several years, financial markets have
     experienced increased volatility, depressed valuations, decreased liquidity
     and heightened uncertainty. These conditions may continue, recur, worsen or
     spread.

     At times, the Fund's investments may represent industries or industry
     sectors that are interrelated or have common risks, making the Fund more
     susceptible to any economic, political or regulatory developments or other
     risks affecting those industries or sectors. The Fund's prospectus contains
     unaudited information regarding the Fund's principal risks. Please refer to
     that document when considering the Fund's principal risks.

2. Management Agreement

PIM manages the Fund's portfolio. Management fees are calculated daily at the
annual rate of 0.60% of the Fund's average daily net assets up to $10 billion
and 0.575% on assets over $10 billion. For the year ended October 31, 2016, the
effective management fee (excluding waivers and/or assumption of expenses) was
equivalent to 0.60% of the Fund's average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting, and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$116,532, in management fees, administrative costs and certain other
reimbursements payable to PIM at October 31, 2016.

3. Transfer Agent

Boston Financial Data Services, Inc. serves as the transfer agent to the Fund at
negotiated rates. Transfer agent fees and payables shown on the Statement of
Operations and the Statement of Assets and Liabilities, respectively, include
sub-transfer agent expenses incurred through the Fund's omnibus relationship
contracts.

38 Pioneer Equity Income Fund | Annual Report | 10/31/16


In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareholder communications activities
such as proxy and statement mailings and outgoing phone calls. For the year
ended October 31, 2016, such out-of-pocket expenses by class of shares were as
follows:



--------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------
                                                           
Class A                                                       $  717,445
Class C                                                          112,445
Class K                                                              993
Class R                                                          186,300
Class Y                                                          664,900
--------------------------------------------------------------------------
  Total                                                       $1,682,083
==========================================================================


4. Distribution and Service Plans

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class C and Class R
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the
average daily net assets attributable to Class C shares. The fee for Class C
shares consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class C shares. Pursuant to the Plan, the
Fund further pays PFD 0.50% of the average daily net assets attributable to
Class R shares for distribution services. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $41,743 in distribution
fees payable to PFD at October 31, 2016.

The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Fund a
service fee of up to 0.25% of the Fund's average daily net assets attributable
to Class R shares held by such plans.

In addition, redemptions of each class of shares (except Class K, Class R and
Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A
CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases
of Class A shares within 12 months of purchase. Redemptions of Class C shares
within 12 months of purchase are subject to a CDSC of 1.00%, based on the lower
of cost or market value of shares being redeemed. Shares purchased as part of an
exchange remain subject to any CDSC that applied to

                        Pioneer Equity Income Fund | Annual Report | 10/31/16 39


the original purchase of those shares. There is no CDSC for Class K, Class R or
Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended
October 31, 2016, CDSCs in the amount of $24,868 were paid to PFD.

5. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund may borrow up to the lesser of the amount available under the facility or
the limits set for borrowing by the Fund's prospectus and the 1940 Act. The
credit facility in effect until February 9, 2016, was in the amount of $240
million. Effective February 10, 2016, the facility is in the amount of $220
million. Under such facility, depending on the type of loan, interest on
borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.85% on
an annualized basis, or the Alternate Base Rate, which is the greater of (a) the
facility's administrative agent's daily announced prime rate on the borrowing
date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus
the overnight Eurodollar rate on the borrowing date. The Funds pay an annual
commitment fee to participate in a credit facility. The commitment fee is
allocated among participating Funds based on an allocation schedule set forth in
the credit agreement.

For the year ended October 31, 2016, the average daily amount of borrowings
outstanding during the period was $7,100,000. The related weighted average
annualized interest rate for the period was 1.25%, and the total interest
expense on such borrowings was $2,094, which is included in interest expense,
located on the Statement of Operations. As of October 31, 2016, there were no
borrowings outstanding.

6. Affiliated Companies

The Fund's investments in certain companies may exceed 5% of the outstanding
voting stock of those companies. Such companies are deemed affiliates of the
Fund for financial reporting purposes. The following summarizes transactions
with affiliates of the Fund for the year ended October 31, 2016:

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareowners of
Pioneer Equity Income Fund:
-------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Equity Income Fund (the "Fund"), as of
October 31, 2016, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the three years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the years ended October 31, 2013, and 2012
were audited by other auditors. Those auditors expressed an unqualified opinion
on those financial statements and financial highlights in their report dated
December 23, 2013.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2016, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Equity Income Fund as of October 31, 2016, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the three
years in the period then ended, in conformity with accounting principles
generally accepted in the United States of America.

ADDITIONAL INFORMATION (unaudited)

For the year ended October 31, 2016, certain dividends paid by the Fund may be
subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax
Relief Reconciliation Act (the Act) of 2003. The Fund intends to designate up to
the maximum amount of such dividends allowable under the Act, as taxed at a
maximum rate of 15%. Complete information will be computed and reported in
conjunction with your 2016 form 1099-DIV.

The qualifying percentage of the Fund's ordinary income dividends for the
purpose of the corporate dividends received deduction was 100%.

Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment
adviser, is currently an indirect, wholly owned subsidiary of UniCredit S.p.A.
("UniCredit"). On December 12, 2016, UniCredit announced that it has entered
into a binding agreement for the sale of its Pioneer Investments business, which
includes the Adviser, to Amundi (the "Transaction"). Amundi is headquartered in
Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in
assets under management worldwide. The closing of the Transaction is expected to
happen in 2017, subject to certain regulatory and antitrust approvals, and other
conditions.

Under the Investment Company Act of 1940, the closing of the Transaction will
cause the Fund's current investment advisory agreement with the Adviser to
terminate. Accordingly, the Fund's Board of Trustees will be asked to approve a
new investment advisory agreement for the Fund. If approved by the Board, the
Fund's new investment advisory agreement will be submitted to the shareholders
of the Fund for their approval.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Equity Income Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether to
renew the investment advisory agreement for the Fund.

The contract review process began in January 2016 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
Contract review materials were provided to the Trustees in March 2016 and May
2016. In addition, the Trustees reviewed and discussed the Fund's performance at
regularly scheduled meetings throughout the year and took into account other
information related to the Fund provided to the Trustees at regularly scheduled
meetings in connection with the review of the Fund's investment advisory
agreement.

In March 2016, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment advisory agreement, and reviewed and
discussed the qualifications of the investment management teams, as well as the
level of investment by the Fund's portfolio managers in the Fund. In May 2016,
the Trustees, among other things, reviewed the Fund's management fee and total
expense ratios, the financial statements of PIM and its parent companies, the
profitability analyses provided by PIM, and possible economies of scale. The
Trustees also reviewed the profitability of the institutional business of PIM
and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with
PIM, "Pioneer"), as compared to that of PIM's fund management business, and
considered the differences between the fees and expenses of the Fund and the
fees and expenses of Pioneer's institutional accounts, as well as the different
services provided by PIM to the Fund and by Pioneer to the institutional
accounts. The Trustees further considered contract review materials in July and
September 2016.

At a meeting held on September 13, 2016, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In approving the
renewal of the investment advisory agreement, the Trustees considered various
factors that they determined were relevant, including the factors described
below. The Trustees did not identify any single factor as the controlling factor
in determining to approve the renewal of the agreement.

                        Pioneer Equity Income Fund | Annual Report | 10/31/16 43


Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed PIM's investment approach
for the Fund and its research process. The Trustees considered the resources of
PIM and the personnel of PIM who provide investment management services to the
Fund. They also reviewed the amount of non-Fund assets managed by the portfolio
managers of the Fund. The Trustees considered the non-investment resources and
personnel of PIM involved in PIM's services to the Fund, including PIM's
compliance and legal resources and personnel. The Trustees noted the substantial
attention and high priority given by PIM's senior management to the Pioneer fund
complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by PIM to the Fund were
satisfactory and consistent with the terms of the investment advisory agreement.

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year data prepared by PIM and information comparing the Fund's
performance with the performance of its peer group of funds as classified by
each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of
the Fund's benchmark index. They also discuss the Fund's performance with PIM on
a regular basis. The Trustees' regular reviews and discussions were factored
into the Trustees' deliberations concerning the renewal of the advisory
agreement.

Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight

44 Pioneer Equity Income Fund | Annual Report | 10/31/16


Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent
third party. In all quintile rankings referred to below, first quintile is most
favorable to the Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the second quintile relative to the management fees paid by
other funds in its Morningstar peer group for the comparable period. The
Trustees also considered the breakpoint in the management fee schedule and the
reduced fee rate above a certain asset level. The Trustees considered that the
expense ratio of the Fund's Class A shares for the most recent fiscal year was
in the second quintile relative to its Morningstar peer group and in the third
quintile relative to its Strategic Insight peer group, in each case for the
comparable period. The Trustees considered the impact of transfer agency,
sub-transfer agency, and other non-management fee expenses on the expense ratios
of the Fund. The Trustees noted that they separately review the Fund's transfer
agency, sub-transfer agency and intermediary arrangements and that the results
of the most recent such review were considered in the consideration of the
Fund's expense ratio.

The Trustees reviewed management fees charged by Pioneer to institutional and
other clients, including publicly offered European funds sponsored by affiliates
of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory
capacity), and unaffiliated foreign and domestic separate accounts. The Trustees
also considered PIM's costs in providing services to the Fund and Pioneer's
costs in providing services to the other clients and considered the differences
in management fees and profit margins for Fund and non-Fund services. In
evaluating the fees associated with Pioneer's client accounts, the Trustees took
into account the respective demands, resources and complexity associated with
the Fund and client accounts. The Trustees noted that, in some instances, the
fee rates for those clients were lower than the management fee for the Fund and
considered that, under the investment advisory agreement with the Fund, PIM
performs additional services for the Fund that it does not provide to those
other clients or services that are broader in scope, including oversight of the
Fund's other service providers and activities related to compliance and the
extensive regulatory and tax regimes to which the Fund is subject. The Trustees
also considered the different entrepreneurial risks associated with PIM's
management of the Fund and Pioneer's management of the other client accounts.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of the services provided by PIM
to the Fund.

                        Pioneer Equity Income Fund | Annual Report | 10/31/16 45


Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results, including the profit margins, realized by PIM and its
affiliates from non-fund businesses. The Trustees considered PIM's profit
margins with respect to the Fund in comparison to the limited industry data
available and noted that the profitability of any adviser was affected by
numerous factors, including its organizational structure and method for
allocating expenses. The Trustees concluded that PIM's profitability with
respect to the management of the Fund was not unreasonable.

Economies of Scale

The Trustees considered PIM's views relating to economies of scale in connection
with the Pioneer Funds as fund assets grow and the extent to which any such
economies of scale are shared with funds and fund shareholders. The Trustees
noted the breakpoint in the management fee schedule. The Trustees recognize that
economies of scale are difficult to identify and quantify, and that, among other
factors that may be relevant, are the following: fee levels, expense
subsidization, investment by PIM in research and analytical capabilities and
PIM's commitment and resource allocation to the Fund. The Trustees noted that
profitability also may be an indicator of the availability of any economies of
scale, although profitability may vary for other reasons including reductions in
expenses. The Trustees concluded that economies of scale, if any, were being
appropriately shared with the Funds.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services provided by PIM
and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. Pioneer is the
principal U.S. asset management business of Pioneer Global Asset Management, the
worldwide asset management business of UniCredit Group, which manages over $150
billion in assets (including the Funds). Pioneer and the Funds receive
reciprocal intangible benefits from the relationship, including mutual brand
recognition and, for the Funds, direct and indirect access to the resources of a
large global asset manager. The Trustees concluded that any such benefits
received by Pioneer as a result of its

46 Pioneer Equity Income Fund | Annual Report | 10/31/16


relationship with the Funds were reasonable and their consideration of the
advisory agreement between the Fund and PIM and the fees thereunder were
unaffected by Pioneer's possible receipt of any such intangible benefits.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that the
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Fund.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

--------------------------------------------------------------------------------

new SEC pre-approval rules, the Fund's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the
services are determined to have a direct impact on the

services provided to an affiliate that required the
Fund's audit committee pre-approval.


(f) If greater than 50 percent, disclose the percentage of hours expended on the

control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is
compatible with maintaining the principal accountant's
independence.

under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

enhanced its internal procedures for reporting performance
information required to be included in prospectuses.

generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of

were revised, and the revised prospectuses were distributed to
shareholders.
