President's Letter

Dear Shareholder,

Through the first three quarters of 2015, global markets experienced pockets of
higher-than-average volatility due to significant cross-currents from different
geographic regions. All year, investors focused on the Federal Reserve System's
(the Fed's) deliberations over when to begin normalizing interest rates.
However, while there were signs of gradual economic improvement in the U.S.,
economies abroad increasingly diverged. In June, for example, investors grew
concerned about the debt crisis in Greece. That news, in turn, was followed by
evidence of an economic slowdown in China, which only served to exacerbate
existing worries about growth trends in the emerging markets, a segment of the
global economy already being negatively impacted by slumping commodity prices,
including the price of crude oil, which has been in near-steady decline for
almost a year. Through September 30, 2015, the pockets of heightened market
volatility alluded to above had resulted in the Standard & Poor's 500 Index
turning in a negative (-5.27%) return over the first nine months of the year.
However, the S&P 500 recovered nicely in October, returning 8.43% for the month,
which boosted the index's year-to-date return into positive territory, at 2.71%.

Despite the headwinds still vexing the global economy, our longer-term view of
the U.S. economy has remained positive. Economic conditions in the U.S. have
generally been constructive, based largely on improvements in employment
statistics and an uptick in the housing sector, which has aided the consumer
side of the economy, where household spending has been rising modestly. U.S.
consumers also stand to benefit, potentially, from lower energy prices as the
winter weather approaches. We continue to believe the U.S. economy remains on
a slow, steady growth trend, and that it is unlikely to be disrupted by a slow
pace of interest-rate normalization by the Fed.

Pioneer Investments believes that investors in today's environment can
potentially benefit from the consistent and disciplined investment approach we
have used since our founding in 1928. We focus on identifying value across
global markets using proprietary research, careful risk management, and a
long-term perspective. Our ongoing goal is to produce compelling returns
consistent with the stated objectives of our investment products, and with our
shareowners' expectations. We believe our shareowners can benefit from the
experience and tenure of our investment teams as well as the insights generated
from our extensive research process.

2 Pioneer Equity Income Fund | Annual Report | 10/31/15


As always, and particularly during times of market uncertainty, 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 your trust in us in the past and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 10/31/15

In the following interview, John Carey, Executive Vice President and Director of
U.S. Portfolio Management at Pioneer Investments, discusses the investment
environment during the 12-month period ended October 31, 2015, 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 would you describe the market environment for equities during the
     12-month period ended October 31, 2015, particularly for the types of
     equities deemed appropriate for the Fund?

A    Returns for the overall equity market were positive for the 12-month
     period. Within the market, however, growth stocks significantly
     outperformed value stocks, as investors were drawn to stocks of companies
     that appeared able to achieve higher earnings in an economy expanding at
     only a moderate pace. Throughout the period there was a market expectation,
     not fulfilled, that the Federal Reserve System (the Fed) would raise
     short-term interest rates, and a resulting cautiousness towards stocks in
     sectors and industries felt to be vulnerable to higher rates, including
     utilities, real-estate investment trusts (REITs), and industrials, among
     others. The strong U.S. dollar - strong to a degree because of that belief
     that rates were going higher - hampered business for many exporting
     companies, particularly machinery manufacturers and consumer-products
     makers. Finally, an intense fascination with the internet, online sales,
     biotech, and other "cutting-edge" enterprises drained investment dollars
     from more "old-line"-type businesses and led to quite strong performance by
     a select list of hyper-growth "stories;" and plodding, sluggish performance
     by many other stocks.

     In that "Tale of Two Cities" stock market environment, the approach that we
     took in managing the Fund was our customary one of emphasizing stocks we
     thought well supported by both attractive valuation and appreciation
     potential. The strategy of Pioneer Equity Income Fund is to "back into
     growth" by looking first at a company's record of dividend* payments. We
     place special emphasis on owning stocks that have paid dividends over
     multiple years and at rising levels.

     We seek to own shares of companies able to achieve such track records as
     the result of steady and growing earnings and cash flows. We also look for
     stocks that have not received as much attention as market-leading names -
     and that sometimes positions the Fund in stocks not yet fully priced. One

*    Dividends are not guaranteed.

     byproduct of that process is our happening upon stocks that, from time to
     time, are "taken over" by other entities in mergers and acquisitions, often
     at premium prices relative to the current market. Kraft (consumer staples)
     and Chubb (financials) were two significant portfolio holdings that
     received such offers during the 12-month period, with both contributing
     positively to the Fund's investment results.

Q    How did the Fund perform in that environment during the 12-month period
     ended October 31, 2015?

A    Pioneer Equity Income Fund's Class A shares returned 5.30% at net asset
     value during the 12-month period ended October 31, 2015, while the Fund's
     benchmark, the Russell 1000 Value Index (the Russell Index), returned
     0.53%. During the same period, the average return of the 497 mutual funds
     in Lipper's Equity Income Funds category was 0.08%, and the average return
     of the 1,377 mutual funds in Morningstar's Large Value Funds category was
     0.37%.

Q    The Fund outperformed the Russell Index benchmark during the 12-month
     period ended October 31, 2015. Could you please discuss the major reasons
     for the Fund's benchmark-relative outperformance?

A    Most of the benchmark-relative outperformance in the Fund's portfolio
     during the period came from stock selections, but sector allocations also
     contributed positively to relative returns. The main sector-allocation
     contributing factor was the Fund's large underweight to energy, the
     poorest-performing sector in the Russell Index during the period. With
     regard to energy, we were skeptical that oil and gas prices would bounce
     back quickly from the nosedive they took after the middle of the 2014
     calendar year, and we were also concerned about the sustainability of
     dividend payments in a sector with plummeting earnings. On the negative
     side of asset allocation, a portfolio overweight to the likewise
     poor-performing materials sector hurt relative results, but stock selection
     in the sector was good, nearly offsetting the performance loss from the
     sector-weighting decision.

     The bulk of the Fund's strong benchmark-relative performance during the
     period resulted from gains on individual stocks held in the portfolio. We
     have already mentioned Kraft and Chubb, recipients of take-over offers.
     Other meaningful, positive performance attribution came from the Fund's
     holdings in Dr. Pepper Snapple (consumer staples), Cedar Fair (consumer
     discretionary), Mondelez International (consumer staples), NVIDIA
     (information technology), and Pinnacle Foods (consumer staples). The

                         Pioneer Equity Income Fund | Annual Report | 10/31/15 5


     Fund's returns also benefited from not owning, or owning only relatively
     modest amounts of, performance laggards such as Chevron, ExxonMobil, and
     Wal-Mart Stores.

     Security selection results were not all positive during the 12-month
     period, however, as the Fund lost some benchmark-relative performance on
     positions in Canadian Imperial Bank (financials) and Syngenta (materials).
     The problems plaguing the natural-resources industries affected the
     Canadian economy and diminished prospects for growth in the banking
     industry, and so we sold the Fund's position in Canadian Imperial during
     the period. Syngenta received, but spurned, a rich acquisition offer from
     Monsanto, which ultimately pulled its offer and walked away, causing a
     decline in Syngenta's share price. We have retained the Fund's position in
     Syngenta as we think the shares, at their reduced price, represent
     reasonable value.

Q    What changes did you make to the Fund's portfolio during the 12-month
     period ended October 31, 2015?

A    During the 12-month period, we added somewhat more than two dozen positions
     to the Fund's portfolio and liquidated nearly three dozen, with a net
     reduction of about a half-dozen names.

     Important additions to the portfolio during the period included:
     Consolidated Edison (utilities), an electricity and natural-gas supplier to
     New York City and parts of New Jersey and Pennsylvania; Helmerich & Payne
     (energy), an oil-and-gas drilling company, with a focus on North and South
     America; Mead Johnson Nutrition (consumer staples), provider of nutritional
     products to babies, with important businesses in emerging markets,
     especially China; CBS (consumer discretionary), television and radio
     broadcaster and book publisher; and Hartford Financial Services
     (financials), diversified insurance underwriter. Later in the period, after
     observing the stock's decline with the price of oil, we took advantage of
     what we regarded as an attractive entry point and added shares of Chevron
     (energy), the integrated, international oil, gas, and chemical company we
     mentioned previously.

     Both purchased and sold during the period was Broadcom (information
     technology), developer of integrated circuits for communications. The stock
     jumped after we purchased it, when the company received a premium take-
     over bid, and we decided to take profits and reinvest elsewhere. AGL
     Resources (utilities) likewise received a take-over bid, leading us to sell
     that position. With regard to Kraft, we kept the Fund invested in the stock
     through its merger with Heinz and later sold the portfolio's holding in the
     combined company. A host of other sales from the portfolio during the
     period owed to our thinking that the price of the stock had reached fair

6 Pioneer Equity Income Fund | Annual Report | 10/31/15


     value, that earnings prospects for the company had diminished or that we
     had found better value in other stocks and determined that a substitution
     of names was warranted.

Q    Did the Fund hold any derivatives during the 12-month period ended October
     31, 2015?

A    No. The Fund did not own any derivative positions during the period.

Q    As you noted earlier, the Fund typically places an emphasis on dividend-
     paying stocks. Would you describe the environment for dividends as positive
     or negative during the 12-month period ended October 31, 2015?

A    Generally speaking, investors were cautious towards owning stocks whose
     prices they perceived as receiving meaningful support from their dividend
     yields. Due to the broad expectation that interest rates were soon going to
     rise, investors especially shied away from names they regarded as "bond
     substitutes." While we understand the logic of that view; namely, that
     bonds offering high coupons will present greater competition to stocks
     trading on their dividend yields, we have never quite agreed with it. As
     long as companies can increase earnings over time and thus potentially
     increase their dividends, they stand a chance of competing for investor
     attention with bonds, which usually have fixed coupon rates from issuance
     through maturity. Later in the period, when we thought that weakness in
     some of the so-called bond substitutes presented potentially attractive
     buying opportunities, we added to the Fund's holdings in utilities and
     REITs, among other income-heavy securities. In the event, of course, the
     Fed had still not raised short-term rates by the end of the period, and the
     above-noted investor concerns appeared to become less intense.

Q    What is your outlook for the equity markets as we approach the end of
     calendar 2015 and get ready to usher in a new calendar year?

A    Investor behavior seems much influenced by the state of the economy, and so
     we, too, think about that, even while spending most of our time studying
     and assessing companies. Our view is that the U. S. economy will show
     continued moderate growth into 2016, but with risks. The weakness in
     commodities prices troubles us, as do the soft results for many industrials
     sector names, especially the capital-goods companies. So far, the housing
     and automotive industries are holding up; but, especially in the case of
     autos, one has the sense that promotions and "special offers" are becoming
     more important. Merger-and-acquisition activity, which helped fuel market
     advances over the past couple of years and certainly has benefited the
     Fund's performance, has lost some of its traction as anti-trust cases have
     become more aggressive and opposition has grown to tax-inversion

                         Pioneer Equity Income Fund | Annual Report | 10/31/15 7


     schemes. In our opinion, it is very difficult to see higher profit margins
     at this point without stronger sales; and, particularly for multinational
     companies, the strong U.S. dollar and the weakness of economies elsewhere
     in the world are holding sales back.

     Another key question is what will happen going forward in Europe, Latin
     America, and China? We believe we need to see improvement in those areas,
     along with some lessening of the current and rather acute geopolitical
     risks, if we are to experience markedly higher economic growth in the U.S.

     Therefore, we are cautious, if still on balance constructive, regarding
     economic prospects here at home. Against that backdrop, we think that the
     Fund's strategy of leaning towards value and dividends as well as balance-
     sheet strength - and company management teams committed to returns for
     shareholders - remains the way to go.

     Thank you as always for your support.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

The portfolio invests in REIT securities, the value of which can fall for a
variety of reasons, such as declines in rental income, fluctuating interest
rates, poor property management, environmental liabilities, uninsured damage,
increased competition, or changes in real estate tax laws.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors.

These risks may increase share price volatility.

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.

     shares, respectively, multiplied by the average account value over the
     period, multiplied by 184/365 (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 | 10/31/15

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 that require the management of the Fund
to, among other things, 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 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 | 10/31/15


A.   Security Valuation

     Security transactions are recorded as of trade date. 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. In
     computing the net asset value, securities that have traded on an exchange
     are valued at the last sale price on the principal exchange where they are
     traded. Securities that have not traded on the date of valuation, or
     securities for which sale prices are not available, generally are valued at
     the mean between the last bid and asked prices. Shares of money market
     mutual funds are valued at such funds' net asset value. Cash may include
     overnight time deposits at approved financial institutions.

     Trading in foreign 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.

     Securities for which independent pricing services 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, 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 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, 2015, there were no securities that were valued using fair
     value methods (other than securities that were valued using prices supplied
     by independent pricing services or broker-dealers).

                        Pioneer Equity Income Fund | Annual Report | 10/31/15 35


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.

     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, 2015, the Fund did not accrue any interest or penalties with
     respect to unrecognized 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. generally accepted accounting principles.
     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, 2015, the Fund reclassified $267,833 to decrease undistributed
     net investment income and $267,833 to increase accumulated net realized
     gain on investments to reflect permanent book/tax differences. These
     adjustments have no impact on net assets or the results of operations.

     The tax character of distributions during the year ended October 31, 2015,
     and October 31, 2014, was as follows:



     ---------------------------------------------------------------------------
                                                            2015            2014
     ---------------------------------------------------------------------------
                                                               
     Distributions paid from:
     Ordinary income                                $ 33,166,428     $34,882,719
     Long-term capital gain                          128,314,155      49,279,841
     ---------------------------------------------------------------------------
          Total                                     $161,480,583     $84,162,560
     ===========================================================================

     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2015:



     ---------------------------------------------------------------------------
                                                                            2015
     ---------------------------------------------------------------------------
                                                                 
     Distributable earnings:
     Undistributed ordinary income                                  $  1,546,368
     Undistributed long term capital gain                            110,273,182
     Net unrealized appreciation                                     386,959,818
     ---------------------------------------------------------------------------
          Total                                                     $498,779,368
     ===========================================================================


     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 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 S.p.A.
     (UniCredit), earned $77,483 in underwriting commissions on the sale of
     Class A shares during the year ended October 31, 2015.

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).

     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.

                        Pioneer Equity Income Fund | Annual Report | 10/31/15 37


F.   Risks

     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.

G.   Forward Foreign Currency Contracts

     The Fund may enter into forward foreign currency contracts (contracts) for
     the purchase or sale of a specific foreign currency at a fixed price on a
     future date. All contracts are marked to market daily at the applicable
     exchange rates, and any resulting unrealized appreciation or depreciation
     is recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a contract is offset by entry into a closing
     transaction or extinguished by delivery of the currency. Risks may arise
     upon entering into these contracts from the potential inability of
     counterparties to meet the terms of the contract and from unanticipated
     movements in the value of foreign currencies relative to the U.S. dollar
     (see Note 8).

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, 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, 2015, 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
$72,818, in management fees, administrative costs and certain other
reimbursements payable to PIM at October 31, 2015.

3. Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, provided substantially all transfer agent and
shareowner services to the Fund at negotiated rates.

In addition, the Fund reimbursed PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.

================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $394,079 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at October 31, 2015.

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 $28,948 in distribution
fees payable to PFD at October 31, 2015.

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

                        Pioneer Equity Income Fund | Annual Report | 10/31/15 39


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 PFD. For the year ended
October 31, 2015, CDSCs in the amount of $5,329 were paid to PFD.

5. Expense Offset Arrangements

The Fund entered into certain expense offset arrangements with PIMSS which may
result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended October 31, 2015, the Fund's expenses
were not reduced under such arrangements.

6. 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 June 9, 2015, was in the amount of $215 million.
As of June 9, 2015, the facility is in the amount of $240 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, 2015, the Fund had no borrowings under
the credit facility.

7. 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, 2015:

8. Forward Foreign Currency Contracts

During the year ended October 31, 2015, the Fund had entered into various
forward foreign currency contracts that obligate the Fund to deliver or take
delivery of currencies at specified future maturity dates. Alternatively, prior
to the settlement date of a forward foreign currency contract, the Fund may
close out such contract by entering into an offsetting contract. The average
value of contracts open during the year ended October 31, 2015 was $788,895.
There were no open forward foreign currency contracts at October 31, 2015.

9. Additional Disclosures about Derivative Instruments and Hedging Activities:

The Fund's use of derivatives subjects it to the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Fund.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

Equity risk relates to the fluctuations in the value of financial instruments as
a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange risk), whether caused by factors specific to an
individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

The effect of derivative instruments (not considered to be hedging instruments
for accounting disclosure purposes) on the Statement of Operations by risk
exposure at October 31, 2015 was as follows:

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 as of October 31,
2015, and the related statement of operations for the year then ended and the
statements of changes in net assets and the financial highlights for each of the
two 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, 2012, and 2011 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, 2015, 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, 2015, and the results of its
operations for the year then ended, and the changes in its net assets and the
financial highlights for each of the two 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, 2015, 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 2015 form 1099-DIV.

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

PIM, the Fund's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

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

Subsequent Event (unaudited)

Effective November 2, 2015, Boston Financial Data Service became the transfer
agent to the Fund at negotiated rates.

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 2015 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 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. 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 2015, 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 July 2015,
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 September
2015.

At a meeting held on September 15, 2015, 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 | 10/31/15 45


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

46 Pioneer Equity Income Fund | Annual Report | 10/31/15


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 third quintile relative to its Morningstar peer group and in the third
quintile relative 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.

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 | 10/31/15 47


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 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

48 Pioneer Equity Income Fund | Annual Report | 10/31/15


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.

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.
