President's Letter

Since 1928, active portfolio management based on in-depth, fundamental
research, has been the foundation of Amundi Pioneer's investment approach. We
believe an active management investment strategy is a prudent approach to
investing, especially during periods of market volatility, which can result
from any number of risk factors, including slow U.S. economic growth, rising
interest rates, and geopolitical factors. Of course, in today's global economy,
risk factors extend well beyond U.S. borders. In fact, it's not unusual for
political and economic issues on the international front to cause or contribute
to volatility in U.S. markets.

At Amundi Pioneer, each security under consideration is researched by our team
of experienced investment professionals, who communicate directly with the
management teams of those companies. At the end of this research process, if we
have conviction in a company's business model and management team, and regard
the security as a potentially solid investment opportunity, an Amundi Pioneer
portfolio manager makes an active decision to invest in that security. The
portfolio resulting from these decisions represents an expression of his or her
convictions, and strives to balance overall risk and return opportunity.

As an example, the Standard & Poor's 500 Index -- the predominant benchmark for
many U.S. Large-Cap Core Equity funds -- has 500 stocks. An Amundi Pioneer
portfolio manager chooses to invest in only those companies that he or she
believes can offer the most attractive opportunities to pursue the fund's
investment objective, thus potentially benefiting the fund's shareowners. This
process results in a portfolio that does not own all 500 stocks, but a much
narrower universe.

The same active decision to invest in a company is also applied when we decide
to sell a security, due to changing fundamentals, valuation concerns, or market
risks. We apply this active decision-making across all of our equity,
fixed-income, and global portfolios.

Today, as investors, we have many options. It is our view that active
management can serve shareholders well, not only when markets are thriving, but
also during periods of market volatility and uncertainty, thus making it a
compelling investment choice. As you consider the many choices today, we
encourage you to work with your financial advisor to develop an overall
investment plan that addresses both your short- and long-term goals, and to
implement such a plan in a disciplined manner.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 10/31/19

In the following interview, John A. Carey discusses the market environment for
equities and the factors that affected the performance of Pioneer Equity Income
Fund during the 12-month period ended October 31, 2019. Mr. Carey, Managing
Director, Director of Equity Income, U.S., and a portfolio manager at Amundi
Pioneer Asset Management, Inc. (Amundi Pioneer), is responsible for the
day-to-day management of the Fund, along with Walter Hunnewell, Jr., a vice
president and a portfolio manager at Amundi Pioneer, and Sammi Truong, a vice
president and a portfolio manager at Amundi Pioneer.

Q    How did the Fund perform over the 12-month period ended October 31, 2019?

A    Pioneer Equity Income Fund's Class A shares returned 11.15% at net asset
     value during the 12-month period ended October 31, 2019, while the Fund's
     benchmark, the Russell 1000 Value Index, returned 11.21%. During the same
     period, the average return of the 1,222 mutual funds in Morningstar's Large
     Value Funds category was 9.63%.

Q    How would you describe the market for equities during the 12-month period
     ended October 31, 2019, particularly for the types of equities deemed
     appropriate for the Fund?

A    About a month into the period, the stock market took a steep dive.
     Investors became concerned that what they believed to be excessive
     interest-rate increases by the Federal Reserve (Fed) would slow the
     domestic economy, perhaps even drive the economy into recession. After
     soothing words from the Fed, however, and amidst hopefulness about a
     potential resolution of trade tensions between the United States and China,
     the stock market turned around near the end of 2018 and remained relatively
     strong for the rest of the 12-month period. Growth stocks outperformed
     value stocks, with total returns over the 12-month period of 17.10% for the
     Russell 1000 Growth Index and 11.21% for the Fund's benchmark, the Russell
     1000 Value Index (the Russell Index).

     Declining interest rates over the course of the 12-month period made the
     dividend yield* on the Russell Index attractive, as the current yield on
     the 10-Year U.S. Treasury fell from 3.1% at the beginning of the period to
     1.7% at the end. The dividend yield on the Russell Index also fell during
     the 12-month period, from about 2.8% to 2.5%, as dividend increases by
     index-constituent companies did not quite keep up with share-price

* Dividends are not guaranteed.

     advances; but, the yield on the Russell Index relative to that on the
     10-Year Treasury went from being lower to being higher. That, along with
     signs that the U.S. economy was continuing to grow, if more slowly,
     supported share prices in the value sector of the market.

Q    Could you please discuss the main factors in the fund's benchmark-relative
     performance during the 12-month period ended October 31, 2019, and any
     investments or strategies that significantly helped or detracted from
     returns?

A    The Fund's performance during the 12-month period was roughly flat against
     that of the benchmark Russell Index. Sector-allocation results were neutral
     to the Fund's benchmark-relative performance. With regard to stock
     selection, likewise, very little stood out in comparison to the Russell
     Index.

     Individual portfolio positions that were noteworthy positive attributors
     for the Fund versus the benchmark over the 12-month period included KLA
     (information technology), Reliance Steel & Aluminum (materials), Xilinx
     (information technology), and WEC Energy (utilities). Meanwhile, positions
     in Nordstrom (consumer discretionary), Occidental Petroleum (energy), CBS
     (communication services), and HP (information technology) were at the top
     of the negative performance-attributors list versus the benchmark; however,
     only Nordstrom had as much as a 1% negative effect on the Fund's relative
     returns.

     In the case of Nordstrom, the department-store company, the stock market
     registered disappointment that an attempt by the Nordstrom family to take
     the company private failed. Troubles throughout the "brick-and-mortar"
     retailing sector also turned investors away from the name. We have retained
     the Fund's shares of Nordstrom because we think that management's
     initiatives in store re-design and online selling may yet prove worthwhile,
     and because the shares, at their current price, do not appear to reflect a
     fair value for the company. Occidental Petroleum's decline during the
     12-month period also merits comment. The company's acquisition of Anadarko
     Petroleum was very poorly received by investors, due both to the high price
     that Occidental paid and to the debt-heavy way in which Occidental financed
     the purchase. With troubled situations like Nordstrom and Occidental, we
     choose to be patient for a time if we believe that core strengths of the
     businesses remain intact, but we stay on high alert and will make changes
     to the Fund's positions if we ultimately do not see improvement.

                         Pioneer Equity Income Fund | Annual Report | 10/31/19 5



     On the positive side, the Fund's holdings in the semiconductor sub-sector
     within information technology, particularly KLA and Xilinx, performed very
     well over the 12-month period as the semiconductor industry stayed much
     more profitable than investors had expected it would at such an advanced
     stage of the economic cycle.

Q    Could you highlight some of the more notable changes you made to the Fund's
     portfolio during the 12-month period ended October 31, 2019?

A    In the 12-month period, we added about two dozen positions to the portfolio
     and eliminated about the same number. A sector in which we did some
     significant repositioning was health care, where we boosted the Fund's
     investments in health-care equipment and services and reduced the
     allocations to pharmaceuticals, biotechnology, and life sciences. We judged
     that the portfolio had too much exposure to potential controls on drug
     prices and, at the same time, was underexposed to areas in health care
     where investor sentiment had become quite negative. Accordingly, we scaled
     back a number of the Fund's pharmaceutical positions and added five
     positions in equipment and services: Becton Dickinson, AmerisourceBergen,
     CVS Health, Anthem, and Humana. Another active area for the portfolio has
     been financial services, where JPMorgan Chase and Comerica were new entries
     in the second half of the 12-month period.

     With respect to other changes, we continued to de-emphasize utilities
     stocks during the 12-month period, due to the relatively rich prices of
     stocks in that sector. We closed out a large position in American Electric
     Power, which had performed well during the time the Fund held the shares.
     Finally, we exited positions in several cyclical companies that appeared
     vulnerable to slower economic growth, including General Motors (consumer
     discretionary), International Paper (materials), TOTAL (energy), and Kroger
     (consumer discretionary).

Q    Did the Fund invest in any derivatives during the 12-month period ended
     October 31, 2019?

A    No, the Fund did not invest in derivatives during the 12-month period.

Q    The Fund typically places emphasis on dividend-paying stocks. How would you
     describe the environment for dividends during the 12-month period ended
     October 31, 2019?

A    As we mentioned earlier, dividend yields on the stocks in the Fund's
     investment universe became more attractive during the 12-month period as
     interest rates declined. Income-oriented investors were thus more inclined
     to consider stocks along with or even instead of debt instruments.

6 Pioneer Equity Income Fund | Annual Report | 10/31/19



     While growth stocks remained the primary focus of many investors,
     dividend-paying value stocks found good support levels as the 12-month
     period progressed.

Q    What is your outlook for equities as we approach the end of 2019?

A    The headlines we read are surely of concern, as political and economic
     risks abound. For now, the U.S. economy is still expanding, but corporate
     earnings have stalled. We are watching consumer-confidence numbers and
     unemployment statistics especially closely. Housing and retail sales are
     also potential indicators of where the economy may be trending. With
     uncertainties particularly regarding international trade, companies have
     exercised restraint in their capital spending. Noting that
     price-to-earnings multiples for many stocks are above historical averages,
     we are cautious on the stock market.

     As always, we keep the portfolio substantially fully invested, but we are
     paying even more attention than usual to financial strength and business
     resilience. If, despite everything, the economy gets a "second wind" and
     resumes good growth, we believe the Fund's portfolio is positioned to take
     part in any subsequent rally, but we do find reassurance currently in the
     potential contribution to total return from the dividends paid by the
     companies in the portfolio.

     Thank you, as ever, 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 www.amundipioneer.com/us 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. POP
returns reflect deduction of maximum 5.75% sales charge. NAV returns would have
been lower had sales charges been reflected. 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

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.

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.

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.

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 / $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.

     by the average account value over the period, multiplied by 184/365 (to
     reflect the partial 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 | 10/31/19

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. 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.

Amundi Pioneer Asset Management, Inc., an indirect, wholly owned subsidiary of
Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., serves as the
Fund's investment adviser (the "Adviser"). Amundi Pioneer Distributor, Inc., an
affiliate of Amundi Pioneer Asset Management, Inc., serves as the Fund's
distributor (the "Distributor").

In August 2018, the Securities and Exchange Commission ("SEC") released a
Disclosure Update and Simplification Final Rule. The Final Rule amends
Regulation S-X disclosures requirements to conform them to U.S. Generally
Accepted Accounting Principles ("U.S. GAAP") for investment companies. The
Fund's financial statements were prepared in compliance with the new amendments
to Regulation S-X.

The Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. U.S. GAAP requires the management of the
Fund to make estimates and assumptions that affect the

34 Pioneer Equity Income Fund | Annual Report | 10/31/19



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 gain or loss on investments during the
reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements:

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.

     Fixed-income securities are valued by using prices supplied by independent
     pricing services, which consider such factors as market prices, market
     events, quotations from one or more brokers, Treasury spreads, yields,
     maturities and ratings, or may use a pricing matrix or other fair value
     methods or techniques to provide an estimated value of the security or
     instrument. A pricing matrix is a means of valuing a debt security on the
     basis of current market prices for other debt securities, historical
     trading patterns in the market for fixed-income securities and/or other
     factors. Non-U.S. debt securities that are listed on an exchange will be
     valued at the bid price obtained from an independent third party pricing
     service. When independent third party pricing services are unable to supply
     prices, or when prices or market quotations are considered to be
     unreliable, the value of that security may be determined using quotations
     from one or more broker-dealers.

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 35



     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 the Adviser pursuant
     to procedures adopted by the Fund's Board of Trustees. The Adviser's fair
     valuation team uses fair value methods approved by the Valuation Committee
     of the Board of Trustees. The Adviser'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 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, 2019, no securities were valued using fair value methods
     (other than securities valued using prices supplied by independent pricing
     services, broker-dealers or using a third party insurance industry pricing
     model).

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
     and net of income accrued on defaulted securities.

     Interest and dividend income payable by delivery of additional shares is
     reclassified as PIK (payment-in-kind) income upon receipt and is included
     in interest and dividend income, respectively.

     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.

36 Pioneer Equity Income Fund | Annual Report | 10/31/19



C.   Foreign Currency Translation

     The books and records of the Fund are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates.

     Net realized gains and losses on foreign currency transactions, if any,
     represent, among other things, the net realized gains and losses on foreign
     currency contracts, disposition of foreign currencies and the difference
     between the amount of income accrued and the U.S. dollars actually
     received. Further, the effects of changes in foreign currency exchange
     rates on investments are not segregated on the Statement of Operations from
     the effects of changes in the market prices of those securities, but are
     included with the net realized and unrealized gain or loss on investments.

D.   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 provision for federal income taxes is
     required. As of October 31, 2019, 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 on the Statement of Operations.
     Tax returns filed within the prior three years remain 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 over distributions 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, 2019, the Fund reclassified $111,066 to increase
     distributable earnings and $111,066 to decrease paid-in capital to reflect
     permanent book/tax differences. These adjustments have no impact on net
     assets or the results of operations.

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 37



     The tax character of distributions paid during the years ended October 31,
     2019 and October 31, 2018, were as follows:



     -------------------------------------------------------------
                                              2019           2018
     -------------------------------------------------------------
                                               
     Distributions paid from:
     Ordinary income                  $ 62,285,134   $ 40,557,818
     Long-term capital gain            114,539,832     87,224,412
     -------------------------------------------------------------
        Total                         $176,824,966   $127,782,230
     -------------------------------------------------------------


     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2019:



     -------------------------------------------------------------
                                                              2019
     -------------------------------------------------------------
                                                   
     Distributable earnings:
     Undistributed ordinary income                    $  3,888,825
     Undistributed long-term capital gain               59,428,136
     Net unrealized appreciation                       556,158,348
     -------------------------------------------------------------
         Total                                        $619,475,309
     -------------------------------------------------------------


     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 Real Estate Investment Trust (REIT) holdings, partnerships
     and common stock holdings.

E.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date. The
     Distributor earned $114,675 in underwriting commissions on the sale of
     Class A shares during the year ended October 31, 2019.

F.   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).

38 Pioneer Equity Income Fund | Annual Report | 10/31/19



     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.

G.   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 and sectors. The Fund's investments in
     foreign markets and countries with limited developing markets may subject
     the Fund to a greater degree of risk than investments in a developed
     market. These risks include disruptive political or economic conditions and
     the imposition of adverse governmental laws or currency exchange
     restrictions.

     With the increased use of technologies such as the Internet to conduct
     business, the Fund is susceptible to operational, information security and
     related risks. While the Fund's Adviser has established business continuity
     plans in the event of, and risk management systems to prevent, limit or
     mitigate, such cyber-attacks, there are inherent limitations in such plans
     and systems, including the possibility that certain risks have not been
     identified. Furthermore, the Fund cannot control the cybersecurity plans
     and systems put in place by service providers to the Fund such as Brown
     Brothers Harriman & Co., the Fund's custodian and accounting agent, and DST
     Asset Manager Solutions, Inc., the Fund's transfer agent. In addition, many
     beneficial owners of Fund shares hold them through accounts at
     broker-dealers, retirement platforms and other financial market
     participants over which neither the Fund nor Amundi Pioneer exercises
     control. Each of these may in turn rely on service providers to them, which
     are also subject to the risk of cyber-attacks. Cybersecurity failures or
     breaches at Amundi Pioneer or the Fund's service providers or
     intermediaries have the ability to cause

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 39



     disruptions and impact business operations, potentially resulting in
     financial losses, interference with the Fund's ability to calculate its net
     asset value, impediments to trading, the inability of Fund shareowners to
     effect share purchases, redemptions or exchanges or receive distributions,
     loss of or unauthorized access to private shareowner information and
     violations of applicable privacy and other laws, regulatory fines,
     penalties, reputational damage, or additional compliance costs. Such costs
     and losses may not be covered under any insurance. In addition, maintaining
     vigilance against cyber-attacks may involve substantial costs over time,
     and system enhancements may themselves be subject to cyber-attacks.

     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

The Adviser 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,
2019, the effective management fee (excluding waivers and/or assumption of
expenses) was equivalent to 0.60% (annualized) 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
$128,724 in management fees, administrative costs and certain other
reimbursements payable to the Adviser at October 31, 2019.

3. Transfer Agent

DST Asset Manager Solutions, 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.

40 Pioneer Equity Income Fund | Annual Report | 10/31/19



In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareowner communications activities
such as proxy and statement mailings, and outgoing phone calls. For the year
ended October 31, 2019, such out-of-pocket expenses by class of shares were as
follows:



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

--------------------------------------------------------------------------------
                                                                     
Class A                                                                 $142,601

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


4.   Distribution and Service Plans

The Fund has adopted a distribution plan (the "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 the Distributor 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 the
Distributor 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 the Distributor 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 $30,902 in distribution fees payable to the Distributor at
October 31, 2019.

The Fund also has adopted a separate service plan for Class R shares (the
"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.

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 41



In addition, redemptions of Class A and Class C 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 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 the Distributor. For the year ended October 31, 2019, CDSCs in the amount of
$8,825 were paid to the Distributor.

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.
Effective August 1, 2018 the Fund participates in credit facility that is in
the amount of $250 million. Under such credit facility, depending on the type
of loan, interest on borrowings is payable at the London Interbank Offered Rate
("LIBOR") plus a credit spread. The Funds also 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, 2019, the Fund had no borrowings
under the credit facility.

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 year:



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

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareholders of Pioneer Equity Income Fund:
--------------------------------------------------------------------------------

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Pioneer
Equity Income Fund (the "Fund"), including the schedule of investments, as of
October 31, 2019, 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, the financial highlights for each of the three years in the
period then ended and the related notes (collectively referred to as the
"financial statements"). The financial highlights for the periods ended October
31, 2015 and October 31, 2016 were audited by another independent registered
public accounting firm whose report, dated December 23, 2016, expressed an
unqualified opinion on those financial highlights. In our opinion, the
financial statements present fairly, in all material respects, the financial
position of the Fund at October 31, 2019, 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 its financial highlights for each of the three years in
the period then ended, in conformity with U.S. generally accepted accounting
principles.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our
responsibility is to express an opinion on the Fund's financial statements
based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) ("PCAOB") and are required
to be independent with respect to the Fund in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. The Fund is not required to have,
nor were we engaged to perform, an audit of the Fund's internal control over
financial reporting. As part of our audits, we are required to obtain an
understanding of internal control over financial reporting, 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.

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 43



Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of October 31, 2019, by correspondence with the custodian and brokers.
Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.

                                                           /s/ Ernst & Young LLP

We have served as the Fund's auditor since 2017.

Approval of Investment Management Agreement

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

The contract review process began in January 2019 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 2019,
July 2019 and September 2019. 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 management agreement.

In March 2019, 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 management agreement, and reviewed and
discussed the qualifications of the investment management teams for the Fund,
as well as the level of investment by the Fund's portfolio managers in the
Fund. In July 2019, the Trustees, among other things, reviewed the Fund's
management fees and total expense ratios, the financial statements of APAM and
its parent companies, profitability analyses provided by APAM, and analyses
from APAM as to possible economies of scale. The Trustees also reviewed the
profitability of the institutional business of APAM and APAM's affiliate,
Amundi Pioneer Institutional Asset Management, Inc. ("APIAM" and, together with
APAM, "Amundi Pioneer"), as compared to that of APAM's fund management
business, and considered the differences between the fees and expenses of the
Fund and the fees and expenses of APAM's and APIAM's institutional accounts, as
well as the different services provided by APAM to the Fund and by APAM and
APIAM to the institutional accounts. The Trustees further considered contract
review materials, including additional materials received in response to the
Trustees' request, in September 2019.

At a meeting held on September 17, 2019, based on their evaluation of the
information provided by APAM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment management agreement for another year. In

46 Pioneer Equity Income Fund | Annual Report | 10/31/19



approving the renewal of the investment management 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.

Nature, Extent and Quality of Services

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

The Trustees considered that APAM 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,
APAM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to APAM 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 APAM to the Fund were
satisfactory and consistent with the terms of the investment management
agreement.

Performance of the Fund

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

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 47



Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund
in comparison to the management fees 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 Mutual Fund Research and
Consulting, LLC (Strategic Insight), an independent third party. The peer group
comparisons referred to below are organized in quintiles. Each quintile
represents one-fifth of the peer group. In all peer group comparisons referred
to below, first quintile is most favorable to the Fund's shareowners. The
Trustees noted that they separately review and consider the impact of the
Fund's transfer agency and Fund- and APAM-paid expenses for 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 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 category for the comparable period. The Trustees
considered that the expense ratio of the Fund's Class A shares for the most
recent fiscal year was in the first quintile relative to its Strategic Insight
peer group for the comparable period. The Trustees considered that the expense
ratio of the Fund's Class Y shares for the most recent fiscal year was in the
third quintile relative to its Strategic Insight peer group for the comparable
period.

The Trustees reviewed management fees charged by APAM and APIAM to
institutional and other clients, including publicly offered European funds
sponsored by APAM's affiliates, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered APAM's costs in providing
services to the Fund and APAM's and APIAM'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
APAM's and APIAM's client accounts, the Trustees took into account the
respective demands, resources and complexity associated with the Fund and other
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 management agreement with the Fund, APAM 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 entrepreneurial risks associated with APAM's management of
the Fund.

48 Pioneer Equity Income Fund | Annual Report | 10/31/19




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

Profitability

The Trustees considered information provided by APAM regarding the
profitability of APAM with respect to the advisory services provided by APAM to
the Fund, including the methodology used by APAM in allocating certain of its
costs to the management of the Fund. The Trustees also considered APAM's profit
margin in connection with the overall operation of the Fund. They further
reviewed the financial results, including the profit margins, realized by APAM
and APIAM from non-fund businesses. The Trustees considered APAM's profit
margins 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 APAM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale

The Trustees considered APAM'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 the Fund and Fund shareholders. 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 APAM in research
and analytical capabilities and APAM'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 due to reductions in expenses. The Trustees concluded
that economies of scale, if any, were being appropriately shared with the
Fund.

Other Benefits

The Trustees considered the other benefits that APAM enjoys from its
relationship with the Fund. The Trustees considered the character and amount of
fees paid or to be paid by the Fund, other than under the investment management
agreement, for services provided by APAM and its affiliates. The Trustees
further considered the revenues and profitability of APAM's businesses other
than the Fund business. To the extent applicable, the Trustees also considered
the benefits to the Fund and to APAM and its affiliates from the use of "soft"
commission dollars generated by the Fund to pay for research and brokerage
services.

                        Pioneer Equity Income Fund | Annual Report | 10/31/19 49



The Trustees considered that Amundi Pioneer is the principal U.S. asset
management business of Amundi, which is one of the largest asset managers
globally. Amundi's worldwide asset management business manages over $1.6
trillion in assets (including the Pioneer Funds). The Trustees considered that
APAM's relationship with Amundi creates potential opportunities for APAM, APIAM
and Amundi that derive from APAM's relationships with the Fund, including
Amundi's ability to market the services of APAM globally. The Trustees noted
that APAM has access to additional research and portfolio management
capabilities as a result of its relationship with Amundi and Amundi's enhanced
global presence that may contribute to an increase in the resources available
to APAM. The Trustees considered that APAM and the Fund receive reciprocal
intangible benefits from the relationship, including mutual brand recognition
and, for the Fund, direct and indirect access to the resources of a large
global asset manager. The Trustees concluded that any such benefits received by
APAM as a result of its relationship with the Fund were reasonable.

Conclusion

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

 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 Amudi Pioneer Asset Management, Inc, 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.
