LETTER TO SHAREOWNERS 12/31/05
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
As 2005 came to a close, U.S. investors looked back on a year of major
challenges, though without much change in the market indices. The war in Iraq
continued, oil prices soared, then dropped, while short-term interest rates
ratcheted steadily higher and intermediate and long-term rates stayed about the
same. Natural disasters also threatened economic expansion. Still, the economy
moved forward as corporate earnings grew. The hope of a growing economy was not
reflected by the small gains or losses in the major U.S. market indices. Among
capitalization ranges, midcap issues made the most headway. Bond prices held
firm and yields remained low, perhaps a sign that the Federal Reserve Board's
interest rate hikes would temper the inflationary pressures induced by a growing
economy.

Among the nagging issues facing the U.S. economy in 2006 is the potential impact
of high energy prices on consumer spending and corporate profits. Also unknown
at this time is whether the Federal Reserve Board will continue to raise
interest rates under its new chairman, Ben Bernanke, who stated his top priority
will be to maintain continuity.

Rising interest rates and improving business conditions made U.S. holdings more
attractive to foreign investors, helping to strengthen the dollar versus the
euro and other key currencies. Investors in many foreign markets enjoyed stellar
returns. Double-digit gains were widespread in Europe, Asia and Latin America.
Even the long-dormant Japanese economy began to stir, while emerging markets,
especially those rich in natural resources, fed global economic growth.

The disparity of returns among countries and sectors underscores the importance
for investors to maintain a well-diversified portfolio. We believe this may be a
good time for investors to review their holdings with their advisor and
determine if they reflect the wide range of opportunities that exist across many
asset classes, as last year's results make clear.

INDEX DEFINITIONS
- --------------------------------------------------------------------------------

The Lehman Brothers Government Bond Index measures the performance of the U.S.

Securities Index is an unmanaged index including 15- and 30-year fixed rate
securities backed by mortgage pools of the Government National Mortgage
Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC) and Federal

dividends and, unlike Trust returns, do not reflect any fees, expenses or sales
charges. You cannot invest directly in the Indexes.

The indexes defined here pertain to the Value of $10,000 Investment charts shown
on pages 4, 5, 6, 7 and 8.

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 4.50% 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 Trust 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 Trust distributions or the redemption of Trust
shares.

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.

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CSDC). Effective December 1, 2004, the period during which a CDSC is applied to
withdrawals was shortened to 5 years. The maximum CDSC for class B shares
continues to be 4%. For more complete information, please see the prospectus for
details. Note: Shares purchased prior to December 1, 2004 remain subject to the
CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

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 Trust 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

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------

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

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Trust 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 Trust 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 Trust'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.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Trust's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Trust'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
Trust 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.

PORTFOLIO MANAGEMENT DISCUSSION 12/31/05
- --------------------------------------------------------------------------------

In a year marked by hurricanes, high energy prices, concerns about accelerating
inflation and rising short-term interest rates, shareholders in Pioneer America
Income Trust earned a positive return on their investment. In the interview
below, Richard Schlanger, the Trust's day-to-day Portfolio Manager, discusses
the factors that affected the fixed-income market and the Trust over the past 12
months.

Q:   How did the Trust perform during the period?

A:   For the 12-month period ended December 31, 2005, Class A shares of Pioneer
     America Income Trust produced a total return of 1.84% at net asset value.
     The Trust underperformed its benchmark, the Lehman Brothers Government Bond
     Index, which returned 2.65% for the same period. It also underperformed the
     average 2.05% return generated by the General U.S. Government Funds
     Category of Lipper, Inc., an independent monitor of mutual fund
     performance. At the end of the period, the 30-day SEC yield for Class A
     shares was 3.17%. The Trust had 260 issues and the average quality of the
     portfolio was AAA.

     Call 1-800-225-6292 or visit www.pioneerfunds.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.

Q:   What was the investment environment like during the period?

A:   Economic growth was relatively strong, and productivity remained high. In
     this environment, the Federal Reserve continued to reverse its
     accommodative monetary policy and raised interest rates eight times during
     the year, each time by a quarter point. At the end of 2005, the federal
     funds target rate was 4.25%, up from 2.25% in January 2005. (The federal
     funds rate is the rate banks charge for overnight loans. Since June 2004,
     the Fed has hiked interest rates 13 times, taking the federal funds rate
     from a 40-year low of 1% to the current 4.25%.) The net effect of the Fed's
     actions was a flattening of the yield curve, where short-term yields and
     longer-term yields were approximately the same. On December 30, 2005, the
     yield curve inverted slightly, with longer-term yields falling below


                                                                              11

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 12/31/05                           (continued)
- --------------------------------------------------------------------------------

     short-term yields. (The yield curve shows the relationship between bond
     yields and maturity lengths.)

     During the year, government bonds benefited from an influx of money from
     both foreign and domestic investors. While long-term yields on U.S.
     Treasuries were relatively low, they were among the highest of the
     developed countries and attractive to overseas investors. The performance
     of government bonds was also enhanced by a flight to quality. At a time
     when long-term yields declined and the debt of General Motors and Ford was
     downgraded by credit rating agencies, domestic investors saw little
     advantage to taking on risk. As a result, they moved into the relative
     safety of government securities.

Q:   What strategies did you use in managing the Trust?

A:   As interest rates rose, we extended duration, or sensitivity to
     interest-rate changes, by reducing exposure to mortgage securities and
     adding to positions in Treasury issues and Treasury Inflation Protected
     Securities (TIPS). TIPS are securities whose principal is tied to the
     consumer price index, a monthly indicator that measures the price inflation
     of a representative basket of goods and services. When inflation
     accelerates, the principal on TIPS increases in value. The interest-rate
     payment on TIPS is calculated on the inflated principal. While inflation
     was not a problem in 2005, we are concerned about the potential for it to
     pick up. Oil prices are over $60 a barrel, the price of gold is at a
     25-year high and the unemployment rate fell below 5%. These factors and
     others could lead to an upturn in inflation. At the end of the period, 59%
     of the portfolio was in mortgage pass-through securities issued by the
     Government National Mortgage Association, 40% was in Treasury issues and
     TIPS, and 1% was in cash.

Q:   What detracted from performance?

A:   Our positioning on the yield curve held back return. Throughout the 12
     months, we maintained a bulleted strategy, which means we invested in bonds
     across the maturity spectrum, with the biggest concentration in the
     intermediate-term range of two-years to ten-years. While our short-term and
     long-term bonds did well, intermediate-term bonds detracted from
     performance. In hindsight, it would have been more advantageous to have had
     a barbelled configuration, overweighting the short and long ends of the
     yield curve and holding relatively few intermediate-term bonds.

Q:   What contributed to performance?

A:   During the second half of 2005, yields on 10-year Treasuries traded in a
     relatively narrow range of roughly 3.90% to a high of roughly 4.68%. As
     10-year Treasuries declined in price and rose in yield, we extended
     duration. This aided results because 10-year Treasuries closed the year at
     4.40%, down from their highs. A longer duration usually benefits a
     portfolio when yields decline. The performance of TIPS also helped boost
     the Trust's return.

Q:   What is your outlook?

A:   In general we are positive when looking ahead. While we believe the
     inverted yield curve may be indicating some moderating in economic growth,
     we do not think it is signaling recession. When the Fed began raising
     interest rates, the federal funds rate was extremely low at 1%. We think
     that the current 4.25% level is not restrictive, especially with an
     inflation rate of roughly 2.0% to 2.5%. While we think the consumer may cut
     back on spending, it is likely that business will pick up the slack. An
     increase in capital spending on the part of corporations may be enough to
     keep the economy growing at a respectable rate. The Fed may be in the late
     stages of its rate-raising cycle. Should the Fed ease rates somewhat, we
     believe intermediate-term securities will outperform longer-term
     securities. We are well-positioned should this occur. As we move into 2006,
     we believe the Trust should continue to provide income diversification for
     investors who want to avoid the risk associated with the more volatile
     areas of the fixed-income market and with equities.

When interest rates rise, the prices of fixed income securities in the fund will
generally fall. Conversely, when interest rates fall, the prices of fixed income
securities in the fund will generally rise. Prepayment risk is the chance that
mortgage-backed bonds will be paid off early if falling interest rates prompt
homeowners to refinance their mortgages. Forced to reinvest the unanticipated
proceeds at lower interest rates, the fund would experience a decline in income
and lose the opportunity for additional price appreciation associated with
falling interest rates. The portfolio may invest in mortgage-backed securities,
which during times of fluctuating interest rates may increase or decrease more
than other fixed-income securities. Mortgage-Backed securities are also subject
to pre-payments. Government guarantees apply to the underlying securities only
and not to the prices and yields of the


                                                                              13

(a)  On January 1, 2001, the Trust began accreting discounts and amortizing
     premiums on debt securities. The effect of this charges for the year ended
     December 31, 2001, was to decrease net investment income by $0.02 per
     share, increase net realized and unrealized gain (loss) by $0.02 per share
     and decrease the ratio of net investment income to average net assets
     assuming waiver of management fees by PIM and reduction for fees paid
     indirectly from 5.35% to 5.15%.

1.   Organization and Significant Accounting Policies

Pioneer America Income Trust (the Trust) is a Massachusetts statutory trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Trust is to
provide a high level of current income consistent with preservation of capital
and prudent investment risk.

The Trustees have authorized the issuance of five classes of shares of the Fund.
The Fund offers five classes of shares designated as - Class A, Class B, Class
C, Investor Class and Class R shares. Class R shares were first publicly offered
on April 1, 2003. Investor Class shares were first issued on December 10, 2004.
The Fund is not offering additional Investor Class shares except in connection
with the reinvestment of dividends on the Fund's outstanding Investor Class
Shares. Each class of shares represents an interest in the same portfolio of
investments of the Trust and has equal rights to voting, redemptions, dividends
and liquidation, except that each class of shares can bear different transfer
agent and distribution fees and has exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B, Class C and Class
R shareowners, respectively. There is no distribution plan for Investor Class
shares.

The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Trust 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 year. Actual results could differ from those estimates. Information
regarding the Trust's principal investment risks is contained in the Trust's
prospectus. Please refer to those documents when considering the Trust's risks.
The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

Pioneer America Income Trust

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

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

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Trust 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 are valued at prices supplied by
     independent pricing services, which consider such factors as Treasury
     spreads, yields, maturities and ratings. Valuations may be supplemented by
     dealers and other sources, as required. Securities for which market
     quotations are not readily available are valued at their fair values as
     determined by, or under the direction of the Board of Trustees. Securities
     for which there are no other readily available valuation methods are valued
     at their fair values as determined by, or under the direction of the Board
     of Trustees. As of December 31, 2005, there were no securities fair valued.
     Principal amounts of mortgage-backed securities are adjusted for monthly
     paydowns. Premiums and discounts related to certain mortgage-backed
     securities are amortized or accreted in proportion to the underlying
     monthly pay downs. All discounts/premiums on debt securities are
     accreted/amortized into interest income on a yield to maturity basis for
     financial reporting purposes. Interest income is recorded on the accrual
     basis. Temporary cash investments are valued at amortized cost.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Federal Income Taxes

     It is the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Trust's distributions may
     be shown in the accompanying financial statements as either from net
     investment income or net realized gain on investment transactions, or from
     paid-in-capital, depending on the type of book/tax differences that may
     exist.


                                                                              37

     $12,125,464, of which $742,335 will expire in 2006, $2,705,283 will expire
     in 2007, $1,526,846 will expire in 2008, $2,070,786 will expire in 2011,
     $3,175,915 will expire in 2012, and $1,904,299 will expire in 2013, if not
     utilized.

     The Trust has elected to defer approximately $1,612,711 of capital losses
     recognized between November 1, 2005 and December 31, 2005 to its fiscal
     year ending December 31, 2006.

     The tax character of distributions paid during the years ended December 31,
     2005 and 2004 were as follows:

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


     The difference between book basis and tax-basis unrealized appreciation is
     primarily attributable to the tax deferral of losses on wash sales and the
     tax treatment of premium and amortization.

     At December 31, 2005, the Trust reclassified $2,360,505 to decrease
     distributions in excess of net investment income, and $2,360,505 to
     increase accumulated net realized loss. This reclassification has no impact
     on the net assets of the Trust and presents the Trust's capital accounts on
     a tax basis.

C.   Fund Shares

     The Trust records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Trust and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.
     (UniCredito Italiano), earned $17,613 in underwriting commissions on the
     sale of Class A shares for the year ended December 31, 2005.

D.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B, Class C and Class R shares of the Trust,
     respectively (See Notes 4). Investor Class Shares are not subject to a
     distribution plan. Shareowners of each class share all expenses and fees
     paid to the transfer agent, Pioneer Investment Management Shareholder
     Services, Inc. (PIMSS), for its services, which are allocated based on the
     number of accounts in each class and the ratable allocation of related
     out-of-pocket expenses (see Note 3). Income, common expenses and realized
     and unrealized gains and losses are calculated at the Trust level and
     allocated daily to each class of shares based on the respective percentage
     of adjusted net assets at the beginning of the day.

     The Trust declares as daily dividends substantially all of its net
     investment income. All dividends are paid on a monthly basis. Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends. Distributions to shareowners are recorded as of the ex-dividend
     date. Distributions paid by the Trust with respect to each class of shares
     are calculated in the same manner, at the same time, and in the same
     amount, except that Class A, Class B, Class C, Investor Class and Class R
     shares can bear different transfer agent and distribution fees.

E.   Repurchase Agreements

     With respect to repurchase agreements entered into by the Trust, the value
     of the underlying securities (collateral), including accrued interest
     received from counter parties, is required to be at least equal to or in
     excess of the value of the repurchase agreement at the time of purchase.
     The collateral for all repurchase agreements is held in safekeeping in the
     customer-only account of the Trust's custodian, or sub custodians. The
     Trust's investment adviser,


                                                                              39

NOTES TO FINANCIAL STATEMENTS 12/31/05                             (continued)
- --------------------------------------------------------------------------------

     Pioneer Investment Management, Inc. (PIM), is responsible for determining
     that the value of the collateral remains at least equal to the repurchase
     price.

2.   Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Trust's portfolio. Management fees are calculated daily at the annual rate of
0.50% of the Trust's average daily net assets.

Through December 10, 2006, PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses (excluding taxes,
commissions, interest and extraordinary expenses) of the Fund to the extent
necessary to limit Investor Class expenses to 0.74% of the average daily net
assets attributable to Investor Class shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Trust. At December 31, 2005, $6,141, was payable to
PIM related to management fees, administrative costs and certain other services,
and is included in due to affiliates.

3.   Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Trust at
negotiated rates. Included in due to affiliates is $74,834 in transfer agent
fees payable to PIMSS at December 31, 2005.

4.   Distribution and Service Plans

The Trust adopted Plans of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan,
the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net
assets attributable to Class A shares in reimbursement of such expenditures to
finance activities primarily intended to result in the sale of Class A shares.
Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of
the average daily net assets attributable to each class of shares. The fee
consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or


40


Pioneer America Income Trust

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

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

account maintenance services or distribution services with regard to Class B and
Class C shares. Pursuant to the Class R Plan, the Trust pays PFD 0.50% of the
average daily net assets attributable to Class R shares as compensation for
distribution services. Included in due to affiliates is $4,932 in distribution
fees payable to PFD at December 31, 2005. The Trust also has adopted a separate
service plan for Class R shares (Service Plan). The Service Plan authorizes the
Trust to pay securities dealers, plan administrators or other services
organizations that agree to provide certain services to retirement plans or plan
participants holding shares of the Trust a service fee of up to 0.25% of the
Trust's daily net assets attributable to Class R shares held by such plans.

In addition, redemptions of each class of shares (except Investor Class) may be
subject to a contingent deferred sales charge (CDSC). Effective February 1,
2004, a CDSC of 1.00% may be imposed on redemptions of certain net asset value
purchases of Class A shares within 18 months of purchase (12 months for shares
purchased prior to February 1, 2004). Class B shares subscribed on or after
December 1, 2004 that are redeemed within five years of purchase are subject to
a CDSC at declining rates beginning at 4.00%, based on the lower of cost or
market value of shares being redeemed. Shares purchased prior to December 1,
2004 remain subject to the CDSC in effect at the time those shares were
purchased. Redemptions of Class C shares within one year of purchase are subject
to a CDSC of 1.00%. Redemption of Class R shares within 18 months of purchase
were subject to a CDSC of 1.00%. Effective July 1, 2004 the CDSC on Class R
shares was eliminated. Proceeds from the CDSCs are paid to PFD. For the year
ended December 31, 2005, CDSCs in the amount of $110,527 were paid to PFD.

5.   Expense Offset Arrangements

The Trust has entered into certain expense offset arrangements with PIMSS,
resulting in a reduction in the Trust's total expenses due to interest earned on
cash held by PIMSS. For the year ended December 31, 2005, the Trust's expenses
were reduced by $7,996 under such arrangements.


                                                                              41

6.   Merger Information

On December 8, 2004, beneficial owners of Safeco Intermediate Term U.S.
Government Fund (one of the Series that comprised Safeco Managed Bond Trust)
approved a proposed Agreement and Plan of Reorganization that provided for the
merger below. This tax-free reorganization was accomplished on December 10,
2004, by exchanging all of Safeco's net assets for Investor Class shares, based
on the Fund's Class A shares' ending net asset value. The following charts show
the details of the reorganizations as of that closing date ("Closing Date"):

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees and Shareowners of
Pioneer America Income Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer America Income Trust (the "Trust") as of
December 31, 2005, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the four years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust'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 year ended December 31, 2001 were
audited by other auditors who have ceased operations and whose report, dated
February 15, 2002, expressed an unqualified opinion on those financial
highlights.

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. We were
not engaged to perform an audit of the Trust's 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 Trust'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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2005, by correspondence with the custodian.
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 America Income Trust at December 31, 2005, 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 financial highlights for each of the four years in
the period then ended, in conformity with U.S. generally accepted accounting
principles.


                                                           /s/ Ernst & Young LLP

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees") vote
separately annually to approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract will enable
the Fund to receive quality investment advisory services at a cost deemed
reasonable and in the best interests of the Fund and its shareholders. In making
such determinations, the Independent Trustees relied upon the assistance of
counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive session
separately from the Interested Trustees of the Fund and any officer of Pioneer
Investment Management, Inc., the Fund's adviser (the "Investment Adviser"), or
its affiliates. While the Trustees, including the Independent Trustees, act on
all major matters relating to the Fund, a significant portion of the activities
of the Board of Trustees (including certain of those described herein) is
conducted through committees, the members of which are comprised exclusively of
Independent Trustees. Such committee meetings are attended by officers of the
Fund or the Investment Adviser to the extent requested by the members of the
committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and relied
upon their knowledge, resulting from their meetings throughout the year, of the
Investment Adviser, its services and the Fund. Both in meetings specifically
dedicated to renewal of the Management Contract and at other meetings during the
course of the year, the Trustees, including the Independent Trustees, received
materials relating to the Investment Adviser's investment and management
services under the Management Contract. These materials included (i) information
on the investment performance of the Fund, a peer group of funds and an index,
in each case selected by the Independent Trustees for this purpose, (ii) sales
and redemption data in respect to the Fund, (iii) the general investment outlook
in the markets in which the Fund invests, (iv) arrangements in respect of the
distribution of the Fund's shares, (v) the procedures employed to determine the
value of each of the Fund's assets, (vi) the Investment Adviser's management of
the relationships with the Fund's unaffiliated service providers, (vii) the
record of compliance with the Fund's investment policies and restrictions and
with the Fund's Code

Pioneer America Income Trust

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


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

of Ethics and the structure and responsibilities of the Investment Adviser's
compliance department, (viii) the nature, cost and character of non-investment
management services provided by the Investment Adviser and its affiliates and
(ix) the disclosures included in the Fund's prospectuses and reports to
shareholders.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested and the Investment
Adviser provided additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one, three, five and ten year periods
for the Fund and a peer group selected by the Independent Trustees for this
purpose, (2) management fees incurred by a peer group of funds selected by the
Independent Trustees for this purpose, (3) the advisory fees of comparable
portfolios of other clients of the Investment Adviser, (4) expense ratios for
the Fund and a peer group of funds selected by the Independent Trustees for this
purpose, (5) the overall organization of the Investment Adviser, (6) the
Investment Adviser's financial results and condition, including its and certain
of its affiliates profitability from services performed for the Fund, (7)
transfer agency fees and administrative reimbursements paid to the Investment
Adviser or affiliates, (8) investment management staffing, and (9) operating
expenses paid to third parties. The Trustees also reviewed information regarding
the potential for the Fund and the Investment Adviser to benefit from further
economies of scale in the management of the Fund in light of reasonable growth
expectations for the Fund and certain of the Fund's expenses that are not
incurred as fees based on a percentage of net assets.

The following summarizes matters considered by the Trustees in connection with
their renewal of the Fund's Management Contract. The Trustees did not identify
any single factor as all-important or controlling, and the summary does not
detail all the matters that were considered.

A.   Ancillary Benefits to Shareholders. The Trustees considered the benefits to
     shareholders of investing in a Fund that is part of a large number of
     investment companies offering a variety of investment disciplines and
     providing for a large variety of Fund and shareholder services.


                                                                              45

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT                                  (continued)
- --------------------------------------------------------------------------------

B.   Compliance and Investment Performance. The Trustees determined that the
     Investment Adviser had policies and systems reasonably designed to achieve
     compliance with the Fund's investment objectives and regulatory
     requirements. The Trustees also reviewed the Fund's investment performance
     based upon total return and yield, as well as the Fund's performance
     compared to both the performance of a peer group and an index, in each case
     selected by the Independent Trustees for this purpose. The Fund's
     performance based upon total return was in the fourth quintile of the peer
     group for the 12 months ended June 30, 2005, the fourth quintile for the
     three years ended June 30, 2005, the fourth quintile for the five years
     ended June 30, 2005 and the fifth quintile for the ten year period ended
     June 30, 2005. (In all quintile rankings referred to throughout this
     discussion first quintile is most favorable to the Fund's shareholders.
     Thus, highest relative performance would be first quintile and lowest
     relative expenses also would be first quintile.) The Trustees also
     considered the yield (gross of expenses) on the Fund's Class A share
     relative to the yield (as of June 30, 2005) on the Lehman Government Bond
     Index. The Trustees noted that the Fund's policy of only investing in
     investments backed by the full faith and credit of the U.S. Treasury had a
     negative impact on performance relative to mutual funds in the peer group
     that can invest in a broader range of U.S. Government Securities. The
     Trustees concluded that, given the more narrow investment mandate than the
     peer group, the performance of the Fund supported the continuation of the
     Management Contract.

C.   The Investment Adviser's Personnel and Methods. The Trustees reviewed the
     background of members of the team responsible for the daily management of
     the Fund and the Fund's investment objective and discipline. The
     Independent Trustees also have had discussions with senior management of
     the Investment Adviser responsible for investment operations and the senior
     management of the Investment Adviser's fixed income group. Among other
     things, the Trustees considered the number, education and experience of the
     Investment Adviser's investment staff and their use of technology and
     emphasis on analytics in view of the risk profile of securities in which
     the Fund invests. The Trustees concluded that the Investment Adviser had
     the quality and depth of personnel and


46


Pioneer America Income Trust

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


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

     the well-developed methods essential to performing its duties under the
     Management Contract.

D.   Nature and Quality of Other Services. The Trustees considered the nature,
     quality, cost and extent of other services provided to shareholders of the
     Fund, including administrative and shareholder services performed by the
     Investment Adviser under the Management Contract. The Trustees also
     considered the reasonableness of the arrangements for reimbursement of the
     Investment Adviser's out-of-pocket costs and expenses, including overhead,
     for certain administrative services that the Investment Adviser is not
     required to provide under the Management Contract. The Trustees also
     considered the nature and extent of the other services provided by the
     Investment Adviser's affiliates under other contracts and its supervision
     of third party service providers. Based on these considerations, the
     Trustees concluded that the nature, quality, cost and extent of such
     services are satisfactory and reliable and serve the shareholders of the
     Fund well.

E.   Management Fee and Expenses. The Trustees considered the Investment
     Adviser's fee under the Management Contract relative to the management fees
     charged by a peer group of funds selected by the Independent Trustees for
     this purpose using data provided by an independent third party. The Fund's
     management fee for the 12 months ended June 30, 2005 was in the third
     quintile relative to the management fees paid by the other funds in that
     peer group for the comparable period. The Trustees determined that the fee
     under the Management Contract was reasonable and fair in light of both the
     overall nature and quality of services provided by the Investment Adviser
     and the fees charged by the funds in the peer group. The Trustees also
     considered the Fund's expense ratio and expense ratios of a peer group of
     funds selected by the Independent Trustees for this purpose. The Fund's
     expense ratio for the 12 months ended June 30, 2005 was in the fifth
     quintile of the applicable peer group for the most recent fiscal year of
     the peer group for the comparable period. The Trustees concluded that the
     Fund's overall expense ratio was acceptable compared to comparably sized
     funds.

F.   Profitability. The Trustees considered the level of the Investment
     Adviser's profits with respect to the management of the Pioneer Funds,
     including details with respect to the Fund. This consideration


                                                                              47

     included a review of the Investment Adviser's methodology in allocating
     certain of its costs to the management of each Fund. The Trustees also
     considered the financial results realized by the Investment Adviser in
     connection with the operation of the Fund. They further considered the
     profits realized by the Investment Adviser and its affiliates from non-fund
     businesses that may benefit from or be related to the Fund's business. The
     Trustees considered the Investment Adviser's profit margins in comparison
     with the limited available industry data. The Trustees concluded that the
     Investment Adviser's profits from management of the Pioneer Funds,
     including the financial results derived from the Fund, bear a reasonable
     relationship to the services rendered and are fair for the management of
     the Fund.

G.   Economies of Scale. The Trustees considered the economies of scale with
     respect to the management of the Fund, whether the Fund had appropriately
     benefited from any economies of scale, and whether there is potential for
     realization of any further economies of scale. The Trustees concluded that,
     given current and anticipated asset levels, break points in the management
     fee were not necessary at this time. As assets increase, the Trustees will
     continue to evaluate annually the appropriateness of break points.

H.   Other Benefits to the Investment Adviser. The Trustees also considered the
     character and amount of fees paid by the Fund, other than under the
     Management Contract, for services provided by the Investment Adviser and
     affiliates, including fees for services such as shareholder services. The
     Trustees also considered the receipt of sales loads and payments under Rule
     12b-1 plans in respect to the Pioneer Funds (including the Fund). The
     Trustees further considered the revenues and profitability of the
     Investment Adviser's businesses other than the fund business, including the
     Investment Adviser's institutional investment advisory business. The
     Trustees considered the intangible benefits that accrue to the Investment
     Adviser and its affiliates by virtue of its relationship with the Fund and
     the Pioneer Funds as a group. The Trustees concluded that all these types
     of benefits accruing to the Investment Adviser were reasonable in the
     context of the overall relationship between the Investment Adviser and the
     Fund.

Conclusion. The Trustees, in light of the Investment Adviser's overall
performance, considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their evaluation of all material
factors deemed relevant and the advice of independent counsel, the Trustees
concluded that the Management Contract with the Fund is fair and reasonable and
voted to approve the continuation of the Management Contract for another year.

         compensatory fee from the issuer; or

    (ii) Be an "interested person" of the investment company as defined in
         Section 2(a)(19) of the Act (15 U.S.C. 80a-2(a)(19)).

Ms. Marguerite A. Piret, an independent trustee, is such an audit committee
financial expert.

    (3) If the registrant provides the disclosure required by paragraph (a)(1)
(ii) of this Item, it must explain why it does not have an audit committee
financial expert.

Not applicable.

 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.

GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

    Non-Audit Services
Beginning with non-audit service contracts entered into on
or after May 6, 2003, the effective date of the new SEC
pre-approval rules, the Fund's audit committee is required
to pre-approve services to affiliates defined by SEC rules
to the extent that the services are determined to have a
direct impact on the operations or financial reporting of the
Trust.

For the years ended December 31, 2005 and 2004, there
were no services provided to an affiliate that required the
Trust's audit committee pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.


The aggregate non-audit fees for the Trust and affiliates, as
previously defined, totaled $6,800 in 2005 and $6,000 in
2004. These fees include services provided prior to May 6,
2003, the effective date of the pre-approval process


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

The Fund's independent auditor, Ernst &
Young LLP ("E&Y"), has advised the Audit
Committee of the Fund's Board of Trustees that
E&Ys Spanish affiliate (E&Y Spain) performed
certain non-audit work for Pioneer Global
Investments Limited ("PGIL"), an affiliate of the
Funds investment adviser.  The services involved
the receipt and disbursement of monies transferred
to E&Y Spain by PGIL in payment of individual
payroll and related income tax withholdings due on
returns prepared by E&Y Spain for certain PGIL
employees located in Spain from February 2001 to
October 2005.  E&Y became auditors of the Fund in
May 2002.  These payroll and tax services were
discontinued in November 2005.  The annual fee
received by E&Y Spain for all such services totaled
approximately 9,000 Euro per year. E&Y has informed
the Audit Committee that based on its internal
reviews and the de minimus nature of the services
provided and fees received, E&Y does not believe
its independence with respect to the Fund has been
impaired or that it is disqualified from acting as
independent auditors to the Fund.

The Trust's audit committee of the Board of Trustees has
considered whether the provision of non-audit services that
were rendered to the Affiliates (as defined) that were not
pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01
of Regulation S-X is compatible with maintaining the
principal accountant's independence.
