April 15, 2002

Dear American Century Limited-Term Tax-Free Fund Shareholder:

I am writing to ask for your support of an important proposal affecting your
fund. The proposal will be voted on at an upcoming Special Meeting of
shareholders to be held on Friday, August 2, 2002. Please take a few minutes to
read the enclosed materials, complete and sign the proxy voting card and mail it
back to us.

At the Special Meeting, you are being asked to elect nominees to serve on the
Board of Trustees of your fund. The enclosed materials give more detailed
information about the nominees. We encourage you to vote "FOR" all the nominees.

In addition, as a shareholder of American Century Limited-Term Tax-Free Fund,
you are being asked to approve the combination of your fund with the American
Century Tax-Free Bond Fund.

The reason for the combination is twofold. First, the reorganization will
combine funds with substantially similar investment objectives and strategies.
Second, management believes it will be more efficient to have the funds'
portfolio management team focus on a single, larger portfolio of assets rather
than continue to manage similar, smaller portfolios.

The Board of Trustees of your fund has unanimously voted in favor of this
reorganization and believes the combination is in your fund's and your best
interests. We encourage you to vote "FOR" the reorganization. The enclosed
materials give more detailed information about the proposed reorganization and
the reasons why we recommend you vote for it.

Please don't put these materials aside, thinking that you will return to them at
another time. If shareholders don't return their proxies, additional expenses
must be incurred to pay for follow-up mailings and phone calls. PLEASE TAKE A
FEW MINUTES TO REVIEW THE ENCLOSED MATERIALS AND VOTE YOUR SHARES TODAY. If you
have any questions or need any help in voting your shares, please call us at
1-800-331-8331.

To more efficiently handle this proxy solicitation, we have hired Alamo Direct
to act as our proxy solicitor. They might be calling you during the solicitation
process to ask if you have questions or concerns about the voting process and to
assist you with your vote.

I appreciate your consideration of this important proposal. Thank you for
investing with American Century and for your continued support.

Sincerely,

William M. Lyons
President

IMPORTANT INFORMATION YOU SHOULD CONSIDER

The following Q&A is a brief summary of some of the issues that may be important
to you. It may not contain all of the information or topics that you think are
important and, as a result, is qualified in its entirety by the more detailed
information contained elsewhere in this document, or incorporated into this
document. Please read all the enclosed proxy materials before voting. PLEASE
REMEMBER TO VOTE YOUR SHARES AS SOON AS POSSIBLE. If enough shareholders return
their proxy cards soon, additional costs for follow-up mailings and phone calls
may be avoided.

What is the purpose of the upcoming meeting?

At the Special Meeting, you are being asked to elect nominees to serve on the
Board of Trustees of American Century Municipal Trust. In addition, your Board
of Trustees has recommended combining Limited-Term Tax-Free into Tax-Free Bond.
This combination requires approval of Limited-Term Tax-Free shareholders. The
Special Meeting to vote on these proposals will be held on Friday, August 2,
2002, at 10:00 a.m. (Central time) at American Century Tower I, 4500 Main
Street, Kansas City, Missouri. Shareholders of record as of the close of
business on April 5, 2002, are eligible to vote.

Who are the nominees for Trustee? Have all of them been elected before?

The Nominating Committee of your Board of Trustees has proposed that
shareholders elect eight members to the Board of Trustees of American Century
Municipal Trust. The nominees are:

Albert Eisenstat
Ronald J. Gilson
Kathryn A. Hall
William M. Lyons
Myron S. Scholes
Kenneth E. Scott
James E. Stowers III
Jeanne D. Wohlers

Albert Eisenstat, Kathryn A. Hall and William M. Lyons are being considered by
shareholders for the first time. A full discussion of the proposal to elect
Trustees begins on page ____ .

When will the proposal regarding the Trustees take effect if it is approved?

The proposal regarding the Trustees will be effective immediately upon approval.

Why is the reorganization being proposed?

The reorganization seeks to improve operational and investment management
efficiencies by combining funds with similar investment objectives and
investment policies, approaches, procedures and portfolio securities. Combining
these similar funds will permit the portfolio management team to focus its
resources on a single, larger fund, rather than divide its time between similar
smaller funds.

How will the reorganization be accomplished?

Shareholders of Limited-Term Tax-Free are being asked to approve the combination
of their fund with Tax-Free Bond according to the Agreement and Plan of
Reorganization described on page ___ . The reorganization will take the form of a
transfer of assets by Limited-Term Tax-Free in exchange for shares of Tax-Free
Bond. Limited-Term Tax-Free will then make a liquidating distribution to its
shareholders of the Tax-Free Bond shares received in the exchange.

What will shareholders get if the reorganization is approved?

As a result of the liquidating distribution, you will receive shares of Tax-Free
Bond in an amount equal to the value of your Limited-Term Tax-Free shares on the
date the combination takes place (probably September 3, 2002). The total dollar
value of your account after the reorganization will be the same as the total
dollar value of your account before the reorganization. However, because the net
asset value (price per share) of Tax-Free Bond may be different from the net
asset value of Limited-Term Tax-Free, you may receive a different number of
shares than the number of shares of Limited-Term Tax-Free that you have. After
the reorganization, you will own shares of Tax-Free Bond rather than shares of
Limited-Term Tax-Free.

Why did the Board of Trustees approve the reorganization?

After reviewing many factors, your Board of Trustees unanimously determined that
the reorganization was in the best interests of Limited-Term Tax-Free and its
shareholders. Some of the factors considered include:

* The potential for enhanced investment performance and increased
efficiency of operations.

* The expense ratio for shareholders will not change as a result of the
reorganization.

* The similarity of investment objectives, policies, restrictions, and
portfolio securities.

* The benefits that may result to the advisor and its affiliates if the
reorganization is consummated.

* The tax consequences to the funds and shareholders if the
reorganization is consummated.

Will the exchange of Limited-Term Tax-Free shares for shares of Tax-Free Bond
cause shareholders to realize income or capital gains for tax purposes?

No. The exchange of shares in the reorganization will be tax-free. We will
obtain a tax opinion confirming that the reorganization will not be a taxable
event for you for federal income tax purposes. Your tax basis and holding period
for your shares will be unchanged.

How does the total expense ratio of Tax-Free Bond compare to that of
Limited-Term Tax-Free?

The total expense ratios of the funds are the same.

Is Tax-Free Bond riskier than Limited-Term Tax-Free?

Only slightly. Each fund invests in quality debt securities issued by cities,
counties and other municipalities. The primary difference between the funds is
their weighted average portfolio maturity and sensitivity to interest rate
changes.

Tax-Free Bond's weighted average portfolio maturity, although unrestricted, is
typically between five and ten years, while Limited-Term Tax-Free's weighted
average portfolio maturity is typically five years or less. Funds with longer
weighted average maturities generally have a higher potential for income, but
they also are more sensitive to interest rate changes. Both Tax-Free Bond and
Limited-Term Tax-Free share values will decline when interest rates rise, but
the share value of the fund with the longer weighted average portfolio maturity,
Tax-Free Bond, generally will decline further.

When and how will the reorganization take place?

Subject to receiving shareholder approval, the reorganization is scheduled to
take place on September 3, 2002. After the funds have calculated the value of
their assets and liabilities on August 30, 2002, Limited-Term Tax-Free will
transfer its assets and liabilities to Tax-Free Bond in exchange for the
appropriate number of Tax-Free Bond shares. Limited-Term Tax-Free will then make
a liquidating distribution of those Tax-Free Bond shares pro rata to its
shareholders according to the value of their accounts immediately prior to the
transfer of assets. THE VALUE OF YOUR ACCOUNT WILL NOT CHANGE AS A RESULT OF
THIS REORGANIZATION.

Will the reorganization affect the management team of Limited-Term Tax-Free?

No. American Century Investment Management, Inc. will continue to manage the
assets of Tax-Free Bond after the reorganization, and the portfolio management
team of Limited-Term Tax-Free also serves as the portfolio management team of
Tax-Free Bond.

How will distribution, purchase and redemption procedures and exchange rights
change as a result of the reorganization?

They won't. Tax-Free Bond has the same distribution, purchase and exchange
policies and procedures as Limited-Term Tax-Free.

How will the proposed changes affect your account?

If the proxy proposals are approved, Limited-Term Tax-Free will be combined with
Tax-Free Bond and your services will be transferred. American Century will
ensure your services will continue and no action is required on your part.
Please review the following information to answer questions you may have about
services and transactions during the proxy period.

Account number

Your account number will change and you will receive a transaction confirmation
with the new number in early September.

Automatic services

If you have any of the services below, they will be transferred and you will
receive a service update as a confirmation.

* automatic investments * direct deposit,
* automatic exchanges * dividend options
* automatic redemptions * required minimum distributions
* automatic transfers

- If you have any of these services, they will occur in August as
scheduled unless we contact you for instructions.

Transactions

- Purchases may be made into your current account until August 16.

- You may continue to make exchanges or redemptions on your current
account through August 30.

CheckWriting

- If you have CheckWriting on your account, please note that this
option is not available with Tax-Free Bond. If you have CheckWriting
checks for other funds, you may continue to use those checks. We will
not honor Limited-Term Tax-Free checks after September 3. All
Limited-Term Tax-Free checks must clear by this date.

If shareholders send their proxies in now as requested, can they change their
vote later?

Yes! A proxy can be revoked at any time using any of the voting procedures
described on your proxy vote card or by attending the meeting and voting in
person. Even if you plan to attend the meeting to vote in person, we ask that
you return the enclosed proxy vote card. Doing so will help us achieve a quorum
for the meeting.

How do shareholders vote their shares?

We've made it easy for you. You can vote online, by phone, by mail or by fax. To
vote online, access the Web site listed on your proxy card (you will need the
control number that appears on the right-hand side of your proxy card). To vote
by telephone, call the toll-free number listed on your proxy card (you will need
the control number that appears on the right-hand side of your proxy card). To
vote by mail, complete, sign and send us the enclosed proxy voting card in the
enclosed postage-paid envelope. To vote by fax, send your fax to the toll-free
number listed on your proxy card.

Your shares will be voted EXACTLY as you tell us. If you simply sign the
enclosed proxy card and return it, we will follow the recommendation of your
Board of Trustees and vote it "FOR" the reorganization. You also may vote in
person at the meeting on Friday, August 2, 2002.

Where can shareholders get more information about the funds?

COMBINED PROSPECTUS/PROXY STATEMENT
AMERICAN CENTURY MUNICIPAL TRUST

April 15, 2002

This Combined Prospectus/Proxy Statement is furnished in connection with the
solicitation of votes by the Board of Trustees of American Century Municipal
Trust on behalf of its Limited-Term Tax-Free Fund ("Limited-Term Tax-Free"), in
connection with a Special Meeting of Shareholders to be held on Friday, August,
2002, at 10:00 a.m. (Central time) at American Century Tower I, 4500 Main
Street, Kansas City, Missouri.

At the Special Meeting, shareholders of Limited-Term Tax-Free are being asked to
elect a Board of Trustees of eight members to hold office until their successors
are duly elected and qualified.

In addition, shareholders of Limited-Term Tax-Free are being asked to approve
the combination of their fund with the American Century Tax-Free Bond Fund,
another series of American Century Municipal Trust ("Tax-Free Bond").

The funds are similarly managed, diversified, open-end mutual funds that invest
in a substantially similar mix of fixed-income securities. The purpose of the
reorganization is to streamline American Century's fixed-income lineup and to
achieve management and operational efficiencies. Combining these similar funds
as described further in this Combined Prospectus/Proxy Statement will help
achieve this objective. Each fund has shares registered with the Securities and
Exchange Commission.

This Combined Prospectus/Proxy Statement constitutes the proxy statement of your
fund for the Special Meeting of Shareholders and a prospectus for the Tax-Free
Bond shares that are to be issued to you in connection with the reorganization.
It is intended to give you the information you need to consider and vote on the
proposed reorganization. You should retain this document for future reference. A
Statement of Additional Information about Tax-Free Bond, dated October 1, 2001,
has been filed with the Commission and is incorporated into this document by
reference. A copy of the Statement of Additional Information may be obtained

PLEASE NOTE THAT THE SPECIAL MEETING OF SHAREHOLDERS WILL BE A BUSINESS MEETING
ONLY AND IS NOT A SHAREHOLDER SEMINAR.

PROPOSAL 1: ELECTION OF TRUSTEES

Nominees

The Board of Trustees of American Century Municipal Trust (the "Trust") has
nominated eight individuals (the "Nominees") for election to the Board. At the
meeting, the shareholders of Limited-Term Tax-Free will be asked to elect the
Nominees to serve on the American Century Municipal Trust Board of Trustees. It
is intended that the enclosed Proxy will be voted for the election of the eight
Nominees named below as Trustees, unless such authority has been withheld in the
Proxy. The term of office of each person elected as Trustee will be until his or
her successor is duly elected and shall qualify. Information regarding each
Nominee is set forth below. Each Nominee has consented to serve as a Trustee if
elected.

Shareholders are being asked to elect the Nominees to serve as Trustees of the
American Century Municipal Trust Board of Trustees in order to ensure that at
least two-thirds of the members of the Board have been elected by the
shareholders of the Trust as required by the Investment Company Act of 1940, as
amended (the "Investment Company Act"). The Investment Company Act provides that
vacancies on the Board of Trustees may not be filled by Trustees unless
thereafter at least two-thirds of the Trustees shall have been elected by
shareholders. To ensure continued compliance with this requirement without
incurring the expense of calling additional shareholder meetings, shareholders
are being asked at this Special Meeting to elect the eight Trustees to hold
office until the next meeting of shareholders. Consistent with the provisions of
the Trust's by-laws, and as permitted by Massachussetts law, the Trust does not
anticipate holding annual shareholder meetings. Thus, the Trustees will be
elected for indefinite terms, subject to termination or resignation. Each
Nominee has indicated a willingness to serve as a member of the Board of
Trustees if elected. If any of the Nominees should not be available for
election, the persons named as proxies (or their substitutes) may vote for other
persons in their discretion. However, the advisor has no reason to believe that
any Nominee will be unavailable for election. In evaluating the Nominees, the
Trustees took into account their background and experience, including their
familiarity with the issues relating to these types of funds and investments as
well as their careers in business, finance, marketing and other areas. The
Trustees also considered the experience of the Nominees as Trustees or Directors
of certain American Century Funds.

INFORMATION REGARDING NOMINEES

The individuals listed in the table below serve as Trustees or officers of
Limited-Term Tax-Free and Tax-Free Bond. Trustees listed as interested persons
of the funds (as defined in the Investment Company Act) are "interested"
primarily by virtue of their engagement as officers of American Century
Companies, Inc. (ACC) or its wholly-owned subsidiaries, including the funds'
investment adviser, American Century Investment Management, Inc. (ACIM); the
funds' principal underwriter, American Century Investment Services, Inc. (ACIS);
and the funds' transfer agent, American Century Services Corporation (ACSC).

The other Trustees, (more than two-thirds of the total number) are independent;
that is, they are not employees or officers of, and have no financial interest
in, ACC or any of its wholly-owned subsidiaries, including ACIM, ACIS and ACSC.

All persons named as officers of the funds also serve in similar capacities for
other funds advised by ACIM. Only officers with policy-making functions are
listed. No officer is compensated for his or her service as an officer of the
funds. The listed officers are interested persons of the funds.

THE BOARD OF TRUSTEES

The Board of Trustees oversees the management of all funds issued by American
Century Municipal Trust and meets at least quarterly to review reports about
fund operations. Although the Board of Trustees does not manage the funds, it
has hired the advisor to do so. The Trustees, in carrying out their fiduciary
duty under the Investment Company Act of 1940, are responsible for approving new
and existing management contracts with the funds' advisor. In carrying out these
responsibilities, the Board reviews material factors to evaluate such contracts,
including (but not limited to) assessment of information related to the
advisor's performance and expense ratios, estimates of income and indirect
benefits (if any) accruing to the advisor, the advisor's overall management and
projected profitability, and services provided to the Funds and their investors.

The Board has the authority to manage the business of the Funds on behalf of
their investors, and it has all powers necessary or convenient to carry out that
responsibility. Consequently, the Trustees may adopt By-laws providing for the
regulation and management of the affairs of the Funds and may amend and repeal
them to the extent that such By-laws do not reserve that right to the funds'
investors. They may fill vacancies in or reduce the number of Board members, and
may elect and remove such officers and appoint and terminate such agents as they
consider appropriate. They may appoint from their own number and establish and
terminate one or more committees consisting of two or more Trustees who may
exercise the powers and authority of the Board to the extent that the Trustees
determine. They may, in general, delegate such authority as they consider
desirable to any officer of the funds, to any committee of the Board and to any
agent or employee of the funds or to any custodian, transfer or investor
servicing agent, or principal underwriter. Any determination as to what is in
the interests of the funds made by the Trustees in good faith shall be
conclusive.

Committees

The Board of Trustees has four standing committees to oversee specific functions
of the funds' operations. Information about these committees appears in the
table below. The Trustee first named serves as chairman of the committee.

Selection of Independent Auditors

The 1940 Act requires that a fund's independent auditors be selected by a
majority of those Trustees who are not "interested persons" (as defined in the
1940 Act) of the Fund. One of the purposes of the Audit Committee is to
recommend to a fund's Board of Trustees the selection, retention or termination
o f independent auditors for the fund. A copy of the Audit Committee's charter,
which describes the Audit Committee's purposes, duties and powers, is attached
as Appendix I to this Prospectus/Proxy Statement.

At meetings held according to the following schedule, the Audit Committee
recommended, and the Board of Trustees/Directors, including a majority of those
Trustees who are not "interested persons," approved the selection of
PricewaterhouseCoopers LLP as the independent auditors for each Fund overseen by
the Board.

PricewaterhouseCoopers LLP, a major international accounting firm, has acted as
auditor of the funds overseen by the Board of Trustees since October 1997. After
reviewing the audited financial statements for the fiscal year ended May 31,
2001, the Audit Committee recommended to the Board of Trustees that such
financial statements be included in each fund's annual report to shareholders. A
copy of the audit committee's report for each fund are attached as Appendix II
to this proxy statement.

Audit Fees. For the fiscal year ending in 2001, PricewaterhouseCoopers LLP
billed American Century funds $754,825.00 for services rendered for the audit
of each fund's annual financial statements.

All Other Fees. For the fiscal years ending in 2001, PricewaterhouseCoopers LLP
billed American Century funds $1,125,719.00 for services other than those
described above. The Audit Committee considered the compatibility of these
non-audit services with PricewaterhouseCoopers' independence.

Compensation of Trustees

The Trustees serve as trustees for eight American Century investment companies.
Each Trustee who is not an interested person as defined in the Investment
Company Act receives compensation for service as a member of the Board of all
eight companies based on a schedule that takes into account the number of
meetings attended and the assets of the funds for which the meetings are held.
These fees and expenses are divided among the eight investment companies based,
in part, upon their relative net assets. Under the terms of the management
agreement with the advisor, the funds are responsible for paying such fees and
expenses.

The following table shows the aggregate compensation paid by all the funds
issued by American Century Municipal Trust for the periods indicated and by the
seven other investment companies served by the Board of Trustees to each Trustee
who is not an interested person as defined in the Investment Company Act.

trustees under the Amended and Restated American Century Mutual Funds
Deferred Compensation Plan for Non-Interested Directors. The total amount
of deferred compensation included in the preceding table is as follows: Mr.
Eisenstat, $28,250; Mr. Gilson, $88,500; Mr. Scholes, $71,750; Mr. Scott,
$40,000; and Ms. Wohlers, $31,515.

2 Includes compensation paid by the eight investment company members of the
American Century family of funds served by this Board.

3 Mr. Stein retired from the Board on September 15, 2000. The amounts shown
represent compensation paid from June 1, 2000 to September 15, 2000.

The funds have adopted the Amended and Restated American Century Deferred
Compensation Plan for Non-Interested Directors. Under the plan, the independent
Trustees may defer receipt of all or any part of the fees to be paid to them for
serving as Trustees of the funds.

All deferred fees are credited to an account established in the name of the
Trustees. The amounts credited to the account then increase or decrease, as the
case may be, in accordance with the performance of one or more of the American
Century funds that are selected by the Trustee. The account balance continues to
fluctuate in accordance with the performance of the selected fund or funds until
final payment of all amounts credited to the account. Trustees are allowed to
change their designation of mutual funds from time to time.

No deferred fees are payable until such time as a Trustee resigns, retires or
otherwise ceases to be a member of the Board of Trustees. Trustees may receive
deferred fee account balances either in a lump sum payment or in substantially
equal installment payments to be made over a period not to exceed 10 years. Upon
the death of a Trustee, all remaining deferred fee account balances are paid to
the Trustee's beneficiary or, if none, to the Trustee's estate.

The plan is an unfunded plan and, accordingly, the funds have no obligation to
segregate assets to secure or fund the deferred fees. To date, the funds have
voluntarily funded their obligations. The rights of Trustees to receive their
deferred fee account balances are the same as the rights of a general unsecured
creditor of the funds. The plan may be terminated at any time by the
administrative committee of the plan. If terminated, all deferred fee account
balances will be paid in a lump sum.

No deferred fees were paid to any Trustee under the plan during the fiscal year
ended May 31, 2001.

Voting Information

Each Nominee will be elected to the Board of Trustees of American Century
Municipal Trust if he or she receives the approval of a majority of the votes of
American Century Municipal Trust represented at the meeting, provided at least a
quorum (50% of the outstanding votes), is represented in person or by proxy. The
election of Trustees is determined by the votes received from all American
Century Municipal Trust shareholders without regard to whether a majority of
shares of any one fund voted in favor of a particular Nominee or all Nominees as
a group. By completing the proxy, you give the named proxies the right to cast
your votes. If you elect to withhold authority for any nominees, you may do so
by striking a line through the Nominee name on the proxy, as further explained
on the proxy itself. The Board of Trustees does not contemplate that any Nominee
will be unable to serve as a member of the Board of Trustees for any reason, but
if that should occur prior to the Special Meeting, the individuals named as
proxies reserve the right to substitute another person or persons of their
choice as Nominee or Nominees.

THE BOARD OF TRUSTEES, INCLUDING THE INDEPENDENT TRUSTEES, UNANIMOUSLY
RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" EACH OF THE NOMINEES.

PRIMARY FEDERAL INCOME TAX CONSEQUENCES

The exchange of Limited-Term Tax-Free shares for Tax-Free Bond shares in the
reorganization will be tax-free to shareholders. We will obtain a tax opinion
confirming that the reorganization will not be a taxable event for shareholders
of either fund for federal income tax purposes. A shareholder's aggregate tax
basis and holding period for Tax-Free Bond shares received in the reorganization
will be identical to the aggregate tax basis and holding period for the
Limited-Term Tax-Free shares exchanged in the transaction. The tax consequences
of the reorganization are described in more detail on page of this Combined
Prospectus/Proxy Statement.

RISK FACTORS

Interest rate changes affect the share value of both Limited-Term Tax-Free and
Tax-Free Bond. Generally, when interest rates rise, the funds' share values will
decline. The opposite is true when interest rates decline. The degree to which
interest rate changes affect a fund's performance varies and is related to the
weighted average maturity of a particular fund. In general, when interest rates
rise, you can expect the share value of a long-term bond fund to fall more than
that of a short-term bond fund. When rates fall, the opposite is true. Because
Tax-Free Bond generally maintains a longer weighted average maturity than
Limited-Term Tax-Free, its share value is generally more sensitive to interest
rate fluctuation than Limited-Term Tax-Free.

Your Board of Trustees does not believe that the reorganization exposes
shareholders of Limited-Term Tax-Free to any substantially new or different
risks than they are exposed to as shareholders of Limited-Term Tax-Free. For a
discussion of the various investment policies, approaches and procedures of
Tax-Free Bond, and the risks associated therewith, please see the accompanying
Prospectus beginning at page 8.

TRANSACTION AND OPERATING
EXPENSE INFORMATION

The tables below compare various shareholder transaction and annual fund
operating expenses of Limited-Term Tax-Free as of its most recent fiscal year
end (May 31, 2001) with Tax-Free Bond as of its most recent fiscal year end
(May 31, 2001). After the reorganization, the expense levels of the surviving
fund will be the same as those shown for Tax-Free Bond (Pro Forma).

1 Based on expenses incurred during the funds' most recent fiscal year. The
funds have stepped fee schedules. As a result, the funds' management fee rate
generally decreases as fund assets increase.

2 Other expenses, which include the fees and expenses of the funds' independent
Trustees, their legal counsel and interest, are expected to be less than 0.005%
for the current fiscal year.

The examples in the table below are intended to help you compare the costs of
investing in a fund with the costs of investing in other mutual funds. Assuming
you . . .

* invest $10,000 in the fund
* redeem all of your shares at the end of the periods shown below
* earn a 5% return each year
* incur the same operating expenses as shown above

. . . your cost of investing in the fund would be:

ADDITIONAL INFORMATION
ABOUT THE PROPOSED TRANSACTION

SUMMARY OF PLAN OF REORGANIZATION

Subject to receipt of shareholder approval, the reorganization will be carried
out according to the terms of the Agreement and Plan of Reorganization between
the funds. The following is a brief summary of some of the important terms of
that Agreement.

EFFECTIVE TIME OF THE REORGANIZATION. The Agreement requires that the exchange
of assets for stock take place after the close of business on one business day
but before (or as of) the opening of business on the next business day (the
"Effective Time"). It is currently anticipated that the reorganization will take
place after the close of business on August 30, 2002, but before (or as of) the
opening of business on September 3, 2002. However, the Agreement gives the
officers of the funds the flexibility to choose another date.

EXCHANGE OF ASSETS. After the close of business on August 30, 2002, the funds
will determine the value of their assets and liabilities in the same manner as
described on page 21 in the enclosed Tax-Free Bond Prospectus. The assets and
liabilities of Limited-Term Tax-Free will then be transferred to Tax-Free Bond
in exchange for that number of full and fractional shares (rounded to the third
decimal place) that have the same aggregate net asset value as the value of the
net assets received in the exchange.

LIQUIDATING DISTRIBUTIONS AND TERMINATION OF LIMITED-TERM TAX-FREE. Immediately
after the exchange of its assets for the Tax-Free Bond shares, Limited-Term
Tax-Free will distribute pro rata all of the shares received in the exchange to
its shareholders of record at the Effective Time. All of the outstanding shares
of Limited-Term Tax-Free will be redeemed and canceled and its stock books
closed. As a result of the distribution, Limited-Term Tax-Free shareholders will
become shareholders of Tax-Free Bond.

SHAREHOLDER APPROVAL. Consummation of the reorganization requires approval of
Limited-Term Tax-Free shareholders.

REPRESENTATIONS AND WARRANTIES. The Agreement contains representations and
warranties made by Limited-Term Tax-Free to Tax-Free Bond concerning
Limited-Term Tax-Free's formation and existence under applicable state law, its
power to consummate the reorganization, its qualification as a "regulated
investment company" under applicable tax law, the registration of its shares
under federal law and other matters that are customary in a reorganization of
this type. The representations and warranties terminate at the Effective Time.

CONDITIONS TO CLOSING. The Agreement contains conditions to closing the proposed
reorganization that benefit each fund. The conditions include (i) that
Limited-Term Tax-Free shareholders approve the proposed reorganization, (ii)
that all representations of the funds be true in all material respects, (iii)
receipt of the tax opinion described on page ______ under the caption "Federal Income
Tax Consequences"," and (iv) such other matters as are customary in a
reorganization of this type.

TERMINATION OF AGREEMENT. The Agreement may be terminated by a fund as a result
of the failure by the other fund to meet one of its conditions to closing, or by
mutual consent.

GOVERNING LAW. The Agreement states that it is to be interpreted under
Massachusetts law, the state of organization of Tax-Free Bond and Limited-Term
Tax-Free.

DESCRIPTION OF THE SECURITIES OF TAX-FREE BOND

Tax-Free Bond is a series of shares offered by American Century Municipal Trust.
Each series is commonly referred to as a mutual fund. The assets belonging to
each series of shares are held separately by the custodian.

American Century Municipal Trust is a Massachusetts business trust, which means
its activities are overseen by a Board of Trustees.

Like Limited-Term Tax-Free, Tax-Free Bond currently offers one class of shares,
the Investor Class, although it may offer additional classes in the future. The
Investor Class of shares of Tax-Free Bond has no up-front charges, commissions
or 12b-1 fees.

Your Board of Trustees believes there are no material differences between the
rights of a Limited-Term Tax-Free shareholder and the rights of a Tax-Free Bond
shareholder. Each share, irrespective of series or class of a series, is
entitled to one vote for each dollar of net asset value applicable to such share
on all questions, except for those matters that must be voted on separately by
the series or class of a series affected. Matters affecting only one class of a
series are voted upon only by that series or class.

Shares have non-cumulative voting rights, which means that the holders of more
than 50% of the votes cast in an election of Trustees can elect all of the
Trustees if they choose to do so, and in such event the holders of the remaining
votes will not be able to elect any person or persons to the Board of Trustees.

Unless required by the Investment Company Act of 1940, it is not necessary for
Tax-Free Bond to hold annual meetings of shareholders. As a result, shareholders
may not vote each year on the election of Trustees. However, pursuant to each
fund's bylaws, the holders of at least 10% of the votes entitled to be cast may
request the fund to hold a special meeting of shareholders.

REASONS SUPPORTING THE REORGANIZATION

The Reorganization is part of a broader restructuring program proposed by
American Century Investment Management, Inc. ("ACIM") to respond to changing
industry conditions and investor needs and desires in the fixed-income area. The
mutual fund industry has grown dramatically over the last ten years. During this
period of rapid growth, investment managers have expanded the range of
fixed-income fund offerings that they make available to investors in an effort
to meet and anticipate the growing and changing needs and desires of an
increasingly large and dynamic group of investors. The family of funds advised
by ACIM has followed this pattern. With this expansion, however, has come
increased complexity and competition among fixed-income mutual funds, as well as
increased confusion among investors.

As a result, ACIM has sought ways to restructure and streamline the management
and operations of the funds it advises. ACIM believes, and has advised the Board
of Trustees, that the consolidation of certain ACIM-advised funds would benefit
fund shareholders. ACIM has, therefore, proposed the consolidation of a number
of ACIM-advised funds that ACIM believes have similar or compatible investment
objectives and policies. In many cases, the proposed consolidations are designed
to eliminate the substantial overlap in current offerings by the American
Century family of funds. Consolidation plans are proposed for other American
Century funds that have not gathered enough assets to operate efficiently and,
therefore, face the risk of closure and resulting tax liability for many
shareholders. ACIM believes that these consolidations may help to enhance
investment performance and increase efficiency of operations.

ACIM recommended to the Board of Trustees that, among other reasons, because the
current market demand for municipal bond funds is generally weak and
Limited-Term Tax-Free and Tax-Free Bond are managed very similarly, the funds
should be combined to establish a larger fund that has substantially similar
investment policies. As part of its analysis, the Board of Trustees recognized
that a large fund may be able to realize certain potential cost savings that
could benefit the shareholders of the funds if the Reorganization is completed.
The Reorganization was also recommended to combine similar funds in an effort to
eliminate duplication of expenses and internal competition. The Board of
Trustees reviewed the expense ratios of both funds and the projected expenses of
the combined fund; the comparative investment performance of the funds; the
compatibility of the investment objectives, policies, restrictions and
investments of the funds; the benefits that may result to ACIM and its
affiliates if the Reorganization is consummated; and the tax consequences of the
Reorganization. The Board of Trustees also noted that the same portfolio
management team manages both funds. During the course of its deliberations, the
Board of Trustees noted that the expenses of the Reorganization will be borne by
ACIM.

The Board of Trustees concluded that the Reorganization is in the best interests
of the shareholders of Limited-Term Tax-Free, and that no dilution of value
would result to the shareholders of the funds from the Reorganization. The Board
of Trustees, including those who are not "interested persons" (as defined in the
1940 Act), approved the Plan and recommended that shareholders of Limited-Term
Tax-Free vote to approve the Reorganization.

FOR THE REASONS DISCUSSED ABOVE, THE BOARD OF TRUSTEES RECOMMENDS THAT YOU VOTE
FOR THE PLAN OF REORGANIZATION.

FEDERAL INCOME TAX CONSEQUENCES

Consummation of the reorganization is subject to the condition that we receive a
tax opinion to the effect that for federal income tax purposes (i) no gain or
loss will be recognized by you, Limited-Term Tax-Free or Tax-Free Bond, (ii)
your basis in the Tax-Free Bond shares that you receive will be the same in the
aggregate as your basis in the Limited-Term Tax-Free shares held by you
immediately prior to the reorganization, and (iii) your holding period for the
Tax-Free Bond shares will include your holding period for your Limited-Term
Tax-Free shares.

We have not sought a tax ruling from the Internal Revenue Service, but are
relying upon the tax opinion referred to above. That opinion is not binding on
the IRS and does not preclude it from taking a contrary position. The opinion
does not cover state or local taxes and you should consult your own advisers
concerning potential tax consequences.

The Agreement and Plan of Reorganization provides that Limited-Term Tax-Free
will declare and pay dividends prior to the reorganization which, together with
all previous dividends, is intended to have the effect of distributing to the
Limited-Term Tax-Free shareholders all undistributed ordinary income, tax-exempt
income, and net realized capital gains earned up to and including the Effective
Time of the reorganization. The distributions are necessary to ensure that the
reorganization will not create adverse tax consequences to Limited-Term
Tax-Free. The distributions to shareholders generally will be taxable to the
extent ordinary income and capital gains distributions are taxable to such
shareholders, and nontaxable to the extent tax-exempt income distributions are
nontaxable to such shareholders.

and avoid the cost of additional proxy solicitation efforts. If you return your
proxy to us, we will vote it EXACTLY as you tell us. If you simply sign the card
and return it, we will follow the recommendation of the Board of Trustees and
vote "FOR" the reorganization.

Any shareholder giving a proxy may revoke it at any time before it is exercised
using any of the voting procedures described on the proxy vote card or by
attending the meeting and voting in person.

RECORD DATE

Only Limited-Term Tax-Free shareholders of record at the close of business on
April 5, 2002, will be entitled to vote at the meeting. The number of
outstanding votes entitled to vote at the meeting or any adjournment of the
meeting as of the close of business on March 15, 2002 is:

Limited-Term Tax-Free

Investor

Because the record date is April 5, 2002, the total number of votes at the
meeting may be different.

QUORUM

A quorum is the number of shareholders legally required to be at a meeting in
order to conduct business. The quorum for the Special Shareholders Meeting is
40% of the outstanding shares of Limited-Term Tax-Free entitled to vote at the
meeting. Shares may be represented in person or by proxy. Proxies properly
executed and marked with a negative vote or an abstention will be considered to
be present at the meeting for purposes of determining the existence of a quorum
for the transaction of business. If a quorum is not present at the meeting, or
if a quorum is present at the meeting but sufficient votes are not received to
approve the Agreement and Plan of Reorganization, the persons named as proxies
may propose one or more adjournments of the meeting to permit further
solicitation of proxies. Any such adjournment will require the affirmative vote
of a majority of those shares affected by the adjournment that are represented
at the meeting in person or by proxy. If a quorum is not present, the persons
named as proxies will vote those proxies for which they are required to vote
"FOR" the Agreement and Plan of Reorganization in favor of such adjournments,
and will vote those proxies for which they are required to vote "AGAINST" such
proposals against any such adjournments.

SHAREHOLDER VOTE REQUIRED

The Agreement and Plan of Reorganization must be approved by the holders of a
majority of the outstanding votes of Limited-Term Tax-Free present at the
Special Meeting in person or by proxy in accordance with the provisions of its
Agreement and Declaration of Trust and the requirements of the Investment
Company Act of 1940. The term "majority of the outstanding shares" means more
than 50% of the fund's outstanding shares present at the Special Meeting in
person or by proxy.

In tallying shareholder votes, abstentions and broker non-votes (i.e., proxies
sent in by brokers and other nominees that cannot be voted on a proposal because
instructions have not been received from the beneficial owners) will be counted
for purposes of determining whether or not a quorum is present for purposes of
convening the meeting. Abstentions and broker non-votes will, however, be
considered to be a vote against the Agreement and Plan of Reorganization.

Approval of the reorganization by shareholders of Tax-Free Bond is not being
solicited because their approval is not legally required.

COST OF PROXY SOLICITATION. The cost of the proxy solicitation and Special
Meeting will be borne by American Century Investment Management, Inc. and NOT by
the shareholders of the funds.

CERTAIN SHAREHOLDERS

The following table lists, as of March 15, 2002, the names, addresses and
percentage of ownership of each person who owned of record or is known by either
fund to own beneficially 5% or more of any class of Limited-Term Tax-Free or

OUR MESSAGE TO YOU

The American Century Tax-Free Bond fund generated exceptionally strong returns
for the year ended May 31, 2001. Demand for bonds surged because of economic
weakness, falling interest rates, and plummeting stock prices. The fund's
investment team reviews the economic and market climate, as well as portfolio
strategy and performance below.

We're pleased to announce some important changes in the investment team's
executive leadership. Effective July 1, 2001, Robert Puff, Jr., president and
chief investment officer (CIO) of American Century Investment Management, Inc.
(ACIM American Century's investment management subsidiary), became the
subsidiary's chairman.

The chairmanship is a newly-created position that allows us to continue to
benefit from Bob's 30 years of investment experience while removing the
responsibility for the day-to-day management of ACIM. Bob can focus more on
business strategy and professional development of investment managers, serving
as a mentor and resource for the various investment management teams.

Randall Merk, formerly a senior vice president and CIO for American Century's
fixed-income discipline, succeeded Bob as ACIM president and CIO. As our top
investment management executive, Randy is responsible for all of American
Century's investment management functions, including portfolio management,
research, and trading.

David MacEwen, a senior vice president who oversaw all of American Century's
municipal and money market portfolios and municipal credit research, assumed
Randy's role as CIO for fixed income. Dave is responsible for portfolio
management and research for all the company's bond and money market products.

And Steven Permut, a vice president and senior portfolio and credit research
manager, was promoted to succeed Dave as leader of American Century's municipal
fund and credit research teams.

Our heartiest congratulations to these investment team leaders and colleagues.
We strongly believe they will continue to serve you and American Century well.
As always, we appreciate your continued confidence in American Century.

Sincerely,

James E. Stowers, Jr. James E. Stowers III
Chairman of the Board and Founder Co-Chairman of the Board

MANAGEMENT Q&A

An interview with Ken Salinger, a portfolio manager on the Tax-Free Bond
investment team.

How did Tax-Free Bond perform during the year ended May 31, 2001?

The fund provided investors a very attractive return that outpaced the Lipper
average. Tax-Free Bond returned 10.77%, not far from double its 5.96% average
annual return of the last 10 years. The 117 "Other States Intermediate Municipal
Debt Funds" tracked by Lipper Inc. returned 9.97% on average. Tax-Free Bond's
three- and five-year returns were even more impressive compared with its peers.

What fueled the fund's very solid return?

As with many short- and intermediate-term bond funds, Tax-Free Bond benefited
from the Federal Reserve's (the Fed's) aggressive interest rate cuts. But we
also made a number of good decisions that boosted the fund's performance above
and beyond that of the Lipper peer average. For example, we continued to shift
the portfolio's exposure to various states when attractive opportunities
presented themselves.

Can you talk about some of your state shifts?

Sure. Take a look at the Top Five States table and you'll notice that the
percentage of the portfolio in Arizona municipals rose during the last six
months. The story there provides a good example of the value plays that we
employ to try and boost returns.

For most of 2000, Arizona experienced fairly low new municipal bond issuance.
But several large bond deals came to market earlier this year, pressuring prices
lower and yields higher. We took advantage of that supply influx to add some of
the state's bonds at what we considered very attractive prices. That play made
sense to us because the outlook for Arizona municipal bond supply lightens
considerably. As new supply dries up, we expect the bonds we added to appreciate
and boost fund returns.

We also selectively added some California municipal bonds. That's why California
municipals represented the portfolio's highest state exposure at the end of May.

Given California's ongoing electric utilities crisis, isn't that increased
exposure a big risk?

Not at all. California definitely faces some challenges concerning electric
power for its residents. And while those challenges aren't likely to be resolved
in the immediate future, we believe we have several important factors working to
limit that risk for shareholders.

The first is our seasoned credit research team, which identified California's
potential power crisis well in advance of the actual event. Thanks to the team,
we held no direct exposure to the California utilities that experienced
financial difficulties. The team also helped us limit the portfolio's indirect
exposure to the situation.

Second, many of the bonds that we picked up are backed by strong California
school districts. In other words, the issuers have solid credit stories that met
our credit research team's strict criteria.

The third helpful factor is bond insurance, which most of the California bonds
in the portfolio have-they're largely rated AAA and backed by bond insurance
companies.

Adding those top-quality California bonds also fit in well with our strategy to
increase the portfolio's AAA holdings. With the economy slowing, we felt adding
high-credit bonds made sense. Simply put, issuers of AAA bonds are less likely
to experience significant financial difficulties during challenging economic
times than are issuers of lower-rated bonds.

Shifting gears, what's your outlook for the economy and interest rates?

The Fed's aggressive short-term interest rate cuts this year should set the
stage for an economic turnaround at some point. But such actions take time to
work through the system. So for the near-term, we're likely to see continued
economic weakness, further corporate profit warnings, and possibly even
additional layoffs.

Given those conditions, we wouldn't be surprised if the Fed reduces rates one or
two more times. But we think that the magnitude of any additional cuts will be
far less aggressive than the ones we've seen so far this year.

With those thoughts in mind, what are your plans for the portfolio?

We feel that the portfolio is fairly well positioned for the current
environment, but we will continue to monitor a few key developments to see
whether modifications are needed. In particular, we may adjust the portfolio's
bond maturity structure (its ratio of short- to intermediate- to long-term
securities) by increasing intermediate-term bond holdings at some point and
decreasing holdings of other maturities.

Are there any other notable changes you're planning for the fund?

Yes. Effective August 8, 2001, we will remove all restrictions on the fund's
weighted average maturity. That is, the fund will be able to invest in municipal
securities across all maturities. Reflecting that average maturity change, the
fund will be renamed "American Century Tax-Free Bond."

How will this affect your investment strategy?

We will still use the same disciplined investment approach, but we will have
more flexibility to look for the best relative values, yields, and appreciation
potential throughout the municipal market. Overall, though, investors aren't
likely to notice big differences in fund strategy or performance. That's because
optimal municipal yields and returns relative to risk (price volatility) still
tend to be found in the intermediate-term maturity area.

What's the main reason for the changes?

We want to help make choosing a municipal bond fund easier for investors. People
who know that they want a tax-advantaged bond investment but aren't sure what
maturity to choose will be able to invest in a "core" municipal fund where we
make the maturity decisions for them.

Class shares.

American Century Municipal Trust

Report of the Audit Committee

The Audit Committee oversees the Fund's financial reporting process on behalf of
the Board of Directors/Trustees. Management has the primary responsibility for
the financial statements and the reporting process including the systems of
internal controls. In fulfilling its oversight responsibilities, the committee
reviewed the audited financial statements in the Annual Report with management
including a discussion of the quality, not just the acceptability, of the
accounting principles, the reasonableness of significant judgments, and the
clarity of disclosures in the financial statements.

The Committee reviewed with the independent auditors, who are responsible for
expressing an opinion on the conformity of those audited financial statements
with generally accepted accounting principles, their judgments as to the
quality, not just the acceptability, of the Fund's accounting principles and
such other matters as are required to be discussed with the Committee under
generally accepted auditing standards. In addition, the Committee has discussed
with the independent auditors the auditors' independence from management and the
Fund including the auditor's letter and the matters in the written disclosure
required by the Independence Standards Board and considered the compatibility of
non-audit services with the auditors' independence.

The Committee discussed with the Fund's independent auditors the overall scope
and plans for the audits. The Committee meets with independent auditors, with
and without management present, to discuss the results of their examinations,
their evaluations of the Fund's internal controls, and the overall quality of
the Fund's financial reporting.

In reliance on the reviews and discussions referred to above, the Committee
recommended to the Board of Trustees/Directors (and the Board has approved) that
the audited financial statements be included in the Annual Report to
shareholders for the year ended May 31, 2001. The Committee and the Board
also have approved the selection of PricewaterhouseCoopers, LLP as the Fund's
independent auditors.

Notes to Pro Forma Financial Statements (unaudited)

1. BASIS OF COMBINATION-The unaudited Pro Forma Combining Schedule of
Investments, Pro Forma Combining Statement of Assets and Liabilities and Pro
Forma Combining Statement of Operations reflect the accounts of the Tax-Free
Bond Fund and Limited-Term Tax-Free Fund (the funds) at and for the year
ended May 31, 2001. The Pro Forma Combining Schedule of Investments and Pro
Forma Combining Statement of Assets and Liabilities assumes the combination
was consummated after the close of business on May 31, 2001. The Pro Forma
Combining Statement of Operations assumes the combination was consummated at
the beginning of the fiscal year ended May 31, 2001.

The pro forma statements give effect to the proposed transfer of the assets
and stated liabilities of the non-surviving fund, Limited-Term Tax-Free, in
exchange for shares of the surviving fund, for purposes of maintaining the
financial statements and performance, Tax-Free Bond. Financial information
for Tax-Free Bond as of May 31, 2001, has been adjusted to reflect the plan
of reorganization effective December 3, 2001, for Tax-Free Bond and Long-Term
Tax-Free. Tax-Free Bond acquired substantially all of the assets of Long-Term
Tax-Free in exchange for shares of equal value of Tax-Free Bond and the
assumption by Tax-Free Bond of all liabilities of Long-Term Tax-Free.

In accordance with accounting principles generally accepted in the United
States of America, the historical cost of investment securities will be
carried forward to the surviving fund and the results of operations for
pre-combination periods for the surviving fund will not be restated. The pro
forma statements do not reflect the expenses of either fund in carrying out
its obligation under the Agreement and Plan of Reorganization. Under the
terms of the Plan of Reorganization, the combination of the funds will be
treated as a tax-free business combination and accordingly will be accounted
for by a method of accounting for tax-free mergers of investment companies.

The Pro Forma Combining Schedule of Investments, Statement of Assets and
Liabilities and Statement of Operations should be read in conjunction with
the historical financial statements of the funds included or incorporated by
reference in the Statement of Additional Information.

2. SECURITY VALUATION- Securities are valued through a commercial pricing
service or at the mean of the most recent bid and asked prices. When
valuations are not readily available, securities are valued at fair value as
determined in accordance with procedures adopted by the Board of Trustees.

3. CAPITAL SHARES-The pro forma net asset value per share assumes the issuance
of shares of the surviving fund that would have been issued at May 31, 2001,
in connection with the proposed reorganization. The number of shares assumed
to be issued is equal to the net asset value of shares of the non-surviving
fund, as of May 31, 2001, divided by the net asset value per share of the
shares of the surviving fund as of May 31, 2001. The pro forma total number
of shares outstanding for the combined fund consists of the following at May
31, 2001:

Total Outstanding Additional Shares
Combined Shares Shares of Assumed Issued
Fund (in thousands) Surviving Fund in Reorganization
----------------------------------------------------------------------------
Tax-Free Bond 32,242 28,697 3,545

4 INVESTMENTS - At May 31, 2001, the funds had the following net realized
capital loss carryovers available to offset future net realized capital gains
for federal income tax purposes. To the extent that those loss carryovers are
used to offset capital gains, it is probable that any gains offset will not
be distributed.

Fund Net Capital Loss Carryover

Tax-Free Bond $1,148,018
Limited-Term Tax-Free $ 302,731
