LETTER TO SHAREOWNERS 6/30/04
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

U.S. equity markets traced a jagged course through the first half of the year,
ending on June 30 only slightly ahead of where they started. Mid-sized and
small-cap indices scored modest gains, while indicators that track large-cap
stocks showed even smaller changes. For bond investors, Treasury issues wound
up the period with higher yields and lower prices than at year-end. The same
was true of corporate issues, whose prices gave ground in the face of rising
interest rates, while high-yield bonds, outstanding performers over recent
quarters, also cooled off.

Although the economic expansion continued to move ahead, investors were
preoccupied with factors that might have undesirable impacts on the economy and
the markets. For one thing, the threat of terrorism is never far from our
minds. For another, the jump in oil prices, attributed to turmoil in the
Mideast and vast demand from China and other developing nations, was a major
factor. The cost of gas or oil for heating our homes, and gasoline for our cars
is a critical component in household budgets. Industry, too, requires energy,
and in many cases petroleum is an essential raw material.

The "jobless" recovery became a job-generating machine for a few months,
followed by a brief slump and a partial rebound. But strong boosts in
employment quickly triggered fears of economic overheating; too much demand for
goods and services, the reasons for aggressive corporate hiring, might trigger
inflation. That would lead to higher interest rates that could choke off the
recovery by causing consumers and businesses to hold back on outlays. In fact,
on June 30, the Federal Reserve Board raised short-term interest rates by
one-quarter percentage point, the first hike in four years.

While there may be further increases, they probably will be gradual; the
Federal Reserve Board would like to keep the expansion intact while keeping
inflation at bay. And even after the Fed's June move, short-term rates remain
near the lowest levels many of us have seen. U.S. businesses, which have done
massive amounts of cost-cutting in recent years, can readily accommodate
somewhat higher borrowing costs. In addition, the federal income tax cuts that
have helped bolster growth over the past several quarters remain in place.

The possibility of higher interest rates and the economy's direction could have
important implications for the way your portfolio is balanced, so an
appointment with your professional financial advisor may well be in order.

PORTFOLIO MANAGEMENT DISCUSSION 6/30/04
- --------------------------------------------------------------------------------

In an improving economy, uncertainty about rising interest rates dominated
market sentiment. As a result, the yields on fixed-income securities declined
and then rose, as investors tried to determine when the Federal Reserve would
raise interest rates and by how much. In this volatile environment, Pioneer
America Income Trust delivered a relatively high level of income to
shareholders. In the interview below, Richard Schlanger, a member of the
Pioneer fixed-income team, discusses the factors that affected the fixed-income
market and the Trust over the past six months.

Q: How did the Trust perform during the six-month period ended June 30, 2004?

A: For the six-month period ended June 30, 2004, Class A shares of Pioneer
   America Income Trust produced a total return of -0.14% at net asset value.
   The Trust performed in line with the Lehman Brothers Government Bond Index,
   which returned -0.13% for the same period. It underperformed the Lehman
   Brothers Fixed-Rate Mortgage-Backed Index, which returned 0.77%. We attribute
   the Fund's underperformance relative to the Lehman Brothers Fixed-Rate
   Mortgage-Backed Index to the fact that the index has significant exposure to
   securities issued by the Federal Home Loan Mortgage Corporation (Freddie Mac)
   and the Federal National Mortgage Association (Fannie Mae), which
   outperformed. Because these securities do not have the backing of the full
   faith and credit of the U.S. Government, we do not invest in them. The Trust
   outperformed the -0.32% 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 4.26%.

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

A: For the first three months of 2004, concerns about geopolitical issues and
   the "jobless" economic recovery kept interest rates at 45-year lows. When we
   moved into the second calendar quarter of 2004, however, the employment
   picture changed dramatically. Several hundred thousand jobs were added to the
   economy in April and May, leading to concerns about accelerating inflation,
   the pace of Federal Reserve tightening and higher interest rates. In


                                                                               7

   this environment, market interest rates rose, causing the yield curve to
   flatten. (The yield curve shows the relationship between bond yields and
   maturity lengths.) Normally, the yield curve is positively sloped, with
   yields on long-term bonds exceeding those on short-term bonds. The yield
   curve flattens when yields on short-term bonds rise more than those on
   long-term bonds, as was the case during the period. As interest rates rose,
   bond yields went up and prices declined.

Q: What investment strategies contributed to performance?

A: Nearly 75% of net assets were invested in mortgage-backed securities issued
   by the Government National Mortgage Association (GNMA), which are backed by
   the full faith and credit of the U.S. government. (A full faith and credit
   backing applies to underlying Trust securities, not to Trust shares.) Because
   GNMA securities outperformed Treasuries, the Trust's focus on mortgages
   relative to the benchmark was the biggest aid to total return. In the
   volatile interest-rate environment, we were concerned about the prepayment
   risk that is associated with mortgage-backed securities. When interest rates
   decline, homeowners often "prepay" their existing mortgages and refinance
   their homes at a lower rate. Significant prepayment activity can result in
   declining yields and share prices in portfolios with investments in
   mortgages. To mitigate this risk, we selected mortgages that had lower
   weighted average coupon (stated rate of interest) rates, which we believe are
   less likely to be prepaid.

Q: What investment strategies detracted from performance?

A: Nearly 25% of the portfolio was invested in Treasury securities with
   predominantly short- and intermediate-term maturities. As yields on
   securities in these maturity ranges moved higher, their prices declined. As a
   result, the Trust's exposure to bonds in the middle of the yield curve held
   back results.

Q: What is your outlook over the next several months?

A: We believe the economy is on a sustained path for improvement and are
   concerned that the seeds for higher inflation are being

   planted. The Federal Reserve raised interest rates by 0.25% on June 30 and is
   likely to continue doing so at a measured pace over the next two years. As
   interest rates move higher, we will consider using a barbell strategy in
   managing the Treasury portion of the Trust - that is, we may sell some of our
   intermediate-term holdings and add securities in the one-to-two-year range
   and in the 20 plus-year range. With this approach, the Trust should benefit
   from the higher yields that long-term bonds provide and from the relative
   price stability of short-term securities. We will also seek mortgage-backed
   securities that are selling at a discount and that can provide the Trust with
   relatively high yields as well as the potential for price appreciation.

   trends or the factors influencing the Trust's historical or future
   performance are statements of the opinion of Trust management as of the date
   of this report. These statements should not be relied upon for any other

   guarantee that market forecasts discussed will be realized.

(a) On January 1,2001, the Trust began accreting discounts and amortizing
    premiums on debt securities. The effect of this changes for the year ended
    December 31, 2001, was to decrease net investment income by $0.01 per share,
    increase net realized and unrealized gain (loss) by $0.01 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
    4.42% to 4.25%. Per share ratios and supplemental data for periods prior to

NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited)
- --------------------------------------------------------------------------------

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 Trust offers four classes of shares - Class A, Class B, Class C and Class R
shares. Class R shares were first publicly offered on April 1, 2003. Shares of
Class A, Class B, Class C and Class R each represent an interest in the same
portfolio of investments of the Trust and have 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.

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 period. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by the Trust, which are in conformity with those generally accepted in the
investment company industry:

A. Security Valuation

   Security transactions are recorded as of trade date. 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
   there are no other readily available valuation method are valued at their
   fair values as determined by, or under the direction of the board of
   Trustees. 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. Securities for which there are no other readily available
   valuation methods are valued at their fair values as determined by, or


                                                                              21


Pioneer America Income Trust

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

   under the direction of the Board of Trustees. As of June 30, 2004, there were
   no securities fair valued. All discounts/premiums on debt securities are
   accreted/amortized 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 amount and characterization of distributions to shareowners for financial
   reporting purposes is determined in accordance with federal income tax rules.
   Therefore, the source 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.

   The tax character of current year distributions paid will be determined at
   the end of the current fiscal year. The tax character of distributions paid
   during the year ended December 31, 2003 was 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.

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 $14,343 in underwriting commissions on the sale
   of Trust shares for the six months ended June 30, 2004.

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. 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 and Class R shares can bear different
   transfer agent and distribution fees.


                                                                              23

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

PIM discontinued the Fund's expense limitation on May 1, 2003. Prior to May 1,
2003, PIM had agreed not to impose a portion of its management fee and to assume
other operating expenses of the Trust to the extent necessary to limit Class A
expenses to 1.00% of the average daily net assets attributable to Class A
shares; the portion of the Trust-wide expenses attributable to Class B, Class C
and Class R shares were reduced only to the extent that such expenses were
reduced for Class A 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 June 30, 2004, $98,414 was payable to PIM
related to management fees, administrative fees 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 $105,634 in transfer agent
fees payable to PIMSS at June 30, 2004.

4. Distribution and Service Plans

The Fund adopted Plans of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan, and Class R Plan)

24


Pioneer America Income Trust

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

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

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 Fund'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 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 for distribution services. Included in due to
affiliates is $100,070 in distribution fees payable to PFD at June 30, 2004. 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 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 one year of purchase.
Class B shares that are redeemed within six 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. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares within 18
months of purchase may be subject to a CDSC of 1.00%. Proceeds from the CDSCs
are paid to PFD. For the six months ended June 30, 2003, CDSCs in the amount of
$137,671 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 six months ended June 30, 2003, the Trust's expenses
were reduced by $1,928 under such arrangements.


                                                                              25

registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must

 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 recognizes 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 recognizes 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

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

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

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.

N/A

(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
