President’s Letter

Jonathan Thomas

Dear Investor:

Thank you for reviewing this annual report for the period ended May 31, 2023. Annual reports help convey important information about fund returns, including market factors that affected performance. For additional investment insights, please visit americancentury.com.

First-Half Challenges Tempered Full-Year Returns

Multidecade-high inflation, rising interest rates and economic uncertainty broadly weighed on fixed-income markets during the first several months of the reporting period. The municipal bond (muni) segment faced additional challenges due to record outflows from the asset class, which persisted throughout 2022.

By period-end, the Federal Reserve’s (Fed’s) aggressive inflation-fighting rate-hike campaign (launched in March 2022) had driven short-term interest rates 5 percentage points higher. The rate hikes pushed Treasury and muni yields to multiyear highs. Meanwhile, after soaring to 9.1% in June 2022, the annual headline inflation rate eased to 4% by May, largely due to the Fed’s tightening campaign.

The fixed-income market backdrop broadly improved in early 2023 amid rising recession risk and growing expectations for the Fed to change course. In addition, generally healthy muni market credit trends and state budget practices further supported municipal bonds. However, a new market headwind emerged: banking industry uncertainty. The collapse of three U.S. regional banks triggered fears of a looming credit crunch and led to periods of volatility.

Despite the period’s ups and downs, positive performance in the second half of the fiscal year more than offset losses in the first half. Investment-grade munis ended May with a modest one-year gain and outperformed U.S. Treasuries, which declined. Although high-yield munis outperformed their investment-grade peers in the period’s second half, they underperformed significantly in the first half and posted a 12-month loss.

Remaining Diligent in Uncertain Times

We expect market volatility to linger as investors navigate a complex environment of still-high inflation, tighter financial conditions, banking industry turbulence and recession risk. In addition, increasingly tense geopolitical considerations complicate the market backdrop.

We appreciate your confidence in us during these extraordinary times. American Century Investments has a long history of helping clients weather unpredictable and volatile markets, and we’re confident we will continue to meet today’s challenges.

Sincerely,

Jonathan Thomas

President and Chief Executive Officer

American Century Investments

Average annual returns since inception are presented when ten years of performance history is not available.

Fund returns would have been lower if a portion of the fees had not been waived.

C Class shares will automatically convert to A Class shares after being held for approximately eight years. C Class average annual returns do not reflect this conversion.

Sales charges include initial sales charges and contingent deferred sales charges (CDSCs), as applicable. A Class shares have a 4.50% maximum initial sales charge and may be subject to a maximum CDSC of 1.00%. C Class shares redeemed within 12 months of purchase are subject to a maximum CDSC of 1.00%. The SEC requires that mutual funds provide performance information net of maximum sales charges in all cases where charges could be applied.

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown. Total returns for periods less than one year are not annualized. Investment return and principal value will fluctuate, and redemption value may be more or less than original cost. Data assumes reinvestment of dividends and capital gains, and none of the charts reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Portfolio Commentary

Portfolio Managers: Joseph Gotelli and Alan Kruss

Performance Summary

High-Yield Municipal returned -3.61%* for the 12 months ended May 31, 2023. By comparison, the S&P Municipal Bond 50% Investment Grade/50% High Yield Index returned -0.78%. Fund returns reflect operating expenses, while index returns do not.

Second-Half Recovery Tempered Earlier Losses

High-yield municipal bonds (munis) demonstrated wide performance swings in the reporting period, with gains in the second half tempering losses in the first half. Similar to all fixed-income sectors, municipal bonds struggled in 2022. Against a backdrop of surging inflation, rising interest rates, hawkish Federal Reserve (Fed) policy and widespread market volatility, munis and other bonds generally declined. Record outflows from the asset class also weighed on the muni sector.

Broad muni market sentiment improved by early 2023, aided by growing expectations for the Fed to change course amid moderating inflation and slowing economic growth. Also, despite declining state tax revenues, strong reserve fund balances and conservative budgeting practices suggested most states were prepared for a slowing economy. Additionally, outflows from the asset class stabilized through the first five months of 2023.

While performance among high-yield munis rebounded in the second half of the period, the bounce back wasn’t sufficient to offset earlier losses. High-yield munis declined modestly for the 12 months and underperformed investment-grade munis.

Security Selection Detracted from Relative Results

Security selection broadly detracted from relative results. Our selections in the special tax, student housing and retirement community sectors accounted for most of the shortfall versus the index. Positive selection results in the tobacco, corporate municipal and multifamily housing sectors helped offset some of those negative effects.

Yield Curve Positioning Weighed on Results

Throughout the reporting period, we overweighted to varying degrees the fund’s duration versus the index’s duration. This positioning weighed on the fund’s relative performance as yields rose—most significantly among shorter maturity securities—and the front end of the yield curve inverted. The remainder of the muni curve remained positively sloped, unlike the U.S. Treasury yield curve.

Sector Allocation Slightly Detracted

Overall, our sector allocation decisions had a slightly negative effect on relative performance. Underweight positions versus the index in state and local general obligation bonds and an overweight in prerefunded securities weighed on results. These weightings offset the positive effects of an underweight position in the multifamily housing sector and an overweight stake in the tobacco sector.

More broadly, our emphasis on high-yield munis versus the index, which holds 50% exposure to investment-grade securities and 50% in high-yield munis, detracted. High-yield munis generally underperformed investment-grade issues for the period.

*All fund returns referenced in this commentary are for Investor Class shares. Performance for other share classes will vary due to differences in fee structure; when Investor Class performance exceeds that of the index, other share classes may not. See page 3 for returns for all share classes.

Shareholder Fee Example

Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from December 1, 2022 to May 31, 2023.

Actual Expenses

The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century Investments mutual fund, or I Class shares of the American Century Diversified Bond Fund, in an American Century Investments account (i.e., not through a financial intermediary or employer-sponsored retirement plan account), American Century Investments may charge you a $25 annual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $25 fee. In determining your total eligible investment amount, we will include your investments in all personal accounts (including American Century Investments brokerage accounts) registered under your Social Security number. Personal accounts include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Investments brokerage accounts, you are currently not subject to this fee. If you are subject to the account maintenance fee, your account value could be reduced by the fee amount.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund’s share class. 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 your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table 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 transactional costs were included, your costs would have been higher.


	Beginning Account Value 12/1/22	Ending Account Value 5/31/23	Expenses Paid During Period(1) 12/1/22 - 5/31/23	Annualized Expense Ratio(1)

(1)Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 182, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. Annualized expense ratio reflects actual expenses, including any applicable fee waivers or expense reimbursements and excluding any acquired fund fees and expenses.

Notes to Financial Statements

MAY 31, 2023

1. Organization

American Century Municipal Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. High-Yield Municipal Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek high current income that is exempt from federal income tax. The fund also seeks capital appreciation as a secondary objective.

The fund offers the Investor Class, I Class, Y Class, A Class and C Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the fund in preparation of its financial statements. The fund is an investment company and follows accounting and reporting guidance in accordance with accounting principles generally accepted in the United States of America. This may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. Management evaluated the impact of events or transactions occurring through the date the financial statements were issued that would merit recognition or disclosure.

Fixed income securities are valued at the evaluated mean as provided by independent pricing services or at the mean of the most recent bid and asked prices as provided by investment dealers. Municipal securities are valued using market models that consider trade data, quotations from dealers and active market makers, relevant yield curve and spread data, creditworthiness, trade data or market information on comparable securities, and other relevant security specific information.

Equity securities that are listed or traded on a domestic securities exchange are valued at the last reported sales price or at the official closing price as provided by the exchange. Equity securities traded on foreign securities exchanges are generally valued at the closing price of such securities on the exchange where primarily traded or at the close of the NYSE, if that is earlier. If no last sales price is reported, or if local convention or regulation so provides, the mean of the latest bid and asked prices may be used. Securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official closing price.

Open-end management investment companies are valued at the reported NAV per share. Exchange-traded futures contracts are valued at the settlement price as provided by the appropriate exchange.

If the valuation designee determines that the market price for a portfolio security is not readily available or is believed by the valuation designee to be unreliable, such security is valued at fair value as determined in good faith by the valuation designee, in accordance with its policies and procedures. Circumstances that may cause the fund to determine that market quotations are not available or reliable include, but are not limited to: when there is a significant event subsequent to the market quotation; trading in a security has been halted during the trading day; or trading in a security is insufficient or did not take place due to a closure or holiday.

The valuation designee monitors for significant events occurring after the close of an investment’s primary exchange but before the fund’s NAV per share is determined. Significant events may include, but are not limited to: corporate announcements and transactions; regulatory news, governmental action and political unrest that could impact a specific investment or an investment sector; or armed conflicts, natural disasters and similar events that could affect investments in a specific country or region. The valuation designee also monitors for significant fluctuations between domestic and foreign markets, as evidenced by the U.S. market or such other indicators that it deems appropriate. The valuation designee may apply a model-derived factor to the closing price of equity securities traded on foreign securities exchanges. The factor is based on observable market data as provided by an independent pricing service.

Security Transactions — Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes.

Investment Income — Interest income is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or long-term capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The fund may estimate the components of distributions received that may be considered nontaxable distributions or long-term capital gain distributions for income tax purposes.

Income Tax Status — It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for income taxes. The fund files U.S. federal, state, local and non-U.S. tax returns as applicable. The fund's tax returns are subject to examination by the relevant taxing authority until expiration of the applicable statute of limitations, which is generally three years from the date of filing but can be longer in certain jurisdictions. At this time, management believes there are no uncertain tax positions which, based on their technical merit, would not be sustained upon examination and for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Multiple Class — All shares of the fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets.

Distributions to Shareholders — Distributions from net investment income, if any, are declared daily and paid monthly. Distributions from net realized gains, if any, are generally declared and paid annually.

Indemnifications — Under the trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The maximum exposure under these arrangements is unknown as this would involve future claims that may be made against a fund. The risk of material loss from such claims is considered by management to be remote.

3. Fees and Transactions with Related Parties

Certain officers and trustees of the trust are also officers and/or directors of American Century Companies, Inc. (ACC). The trust's investment advisor, ACIM, the trust's distributor, American Century Investment Services, Inc. (ACIS), and the trust's transfer agent, American Century Services, LLC, are wholly owned, directly or indirectly, by ACC.

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The difference in the fee among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. The investment advisor will waive the portion of the fund's management fee equal to the expenses attributable to the management fees of the American Century Investments funds in which the fund invests. The amount of this waiver will fluctuate depending on the fund's daily allocation to other American Century Investments funds. This waiver is expected to remain in effect permanently and it cannot be terminated without the approval of the Board of Trustees. The impact of this waiver to the ratio of operating expenses to average net assets was less than 0.005% for each class for the period ending May 31, 2023.

The Investment Category Fee range, the Complex Fee range and the effective annual management fee for each class for the period ended May 31, 2023 are as follows:


	Investment Category Fee Range	Complex Fee Range	Effective Annual Management Fee
Investor Class	0.2925% to 0.4100%	0.2500% to 0.3100%	0.59%
I Class		0.0500% to 0.1100%	0.39%
Y Class		0.0200% to 0.0800%	0.36%
A Class		0.2500% to 0.3100%	0.59%
C Class		0.2500% to 0.3100%	0.59%

Distribution and Service Fees — The Board of Trustees has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class and C Class (collectively the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the A Class will pay ACIS an annual distribution and service fee of 0.25%. The plans provide that the C Class will pay ACIS an annual distribution and service fee of 1.00%, of which 0.25% is paid for individual shareholder services and 0.75% is paid for distribution services. The fees are computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The fees are used to pay financial intermediaries for distribution and individual shareholder services. Fees incurred under the plans during the period ended May 31, 2023 are detailed in the Statement of Operations.

Trustees' Fees and Expenses — The Board of Trustees is responsible for overseeing the investment advisor’s management and operations of the fund. The trustees receive detailed information about the fund and its investment advisor regularly throughout the year, and meet at least quarterly with management of the investment advisor to review reports about fund operations. The fund's officers do not receive compensation from the fund.

Interfund Transactions — The fund may enter into security transactions with other American Century Investments funds and other client accounts of the investment advisor, in accordance with the 1940 Act rules and procedures adopted by the Board of Trustees. The rules and procedures require, among other things, that these transactions be effected at the independent current market price of the security. During the period, the interfund purchases and sales were $40,680,000 and $65,960,000, respectively. The interfund transactions had no effect on the Statement of Operations in net realized gain (loss) on investment transactions.

4. Investment Transactions

Purchases and sales of investment securities, excluding short-term investments, for the period ended May 31, 2023 were $357,245,213 and $458,070,643, respectively.

5. Capital Share Transactions

(1)Investments are funds within the American Century Investments family of funds and are considered affiliated funds. Additional information and attributes of each affiliated fund are available at americancentury.com.

(2)Distributions received includes distributions from net investment income and from capital gains, if any.

7. Investments in Affiliated Funds

The fund does not invest in an affiliated fund for the purpose of exercising management or control; however, investments by the fund within its investment strategy may represent a significant portion of an affiliated fund's net assets.

8. Fair Value Measurements

The fund's investments valuation process is based on several considerations and may use multiple inputs to determine the fair value of the investments held by the fund. In conformity with accounting principles generally accepted in the United States of America, the inputs used to determine a valuation are classified into three broad levels.

•Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

•Level 2 valuation inputs consist of direct or indirect observable market data (including quoted prices for comparable investments, evaluations of subsequent market events, interest rates, prepayment speeds, credit risk, etc.). These inputs also consist of quoted prices for identical investments initially expressed in local currencies that are adjusted through translation into U.S. dollars.

•Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

The level classification is based on the lowest level input that is significant to the fair valuation measurement. The valuation inputs are not necessarily an indication of the risks associated with investing in these securities or other financial instruments.

The following is a summary of the level classifications as of period end. The Schedule of Investments provides additional information on the fund's portfolio holdings.

9. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. A fund may purchase futures contracts to gain exposure to increases in market value or sell futures contracts to protect against a decline in market value. Upon entering into a futures contract, a fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. A fund may incur charges or earn income on cash deposit balances, which are reflected in interest expenses or interest income, respectively. Subsequent payments (variation margin) are made or received daily, in cash, by a fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. A fund recognizes a realized gain or loss when the futures contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of net realized gain (loss) on futures contract transactions and change in net unrealized appreciation (depreciation) on futures contracts, respectively. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. The fund's average notional exposure to interest rate risk derivative instruments held during the period was $37,347,663 futures contracts purchased and $9,513,281 futures contracts sold.

The value of interest rate risk derivative instruments as of May 31, 2023, is disclosed on the Statement of Assets and Liabilities as an asset of $169,313 in receivable for variation margin on futures contracts.* For the year ended May 31, 2023, the effect of interest rate risk derivative instruments on the Statement of Operations was $(2,181,210) in net realized gain (loss) on futures contract transactions and $448,662 in change in net unrealized appreciation (depreciation) on futures contracts.

*Included in the unrealized appreciation (depreciation) on futures contracts as reported in the Schedule of Investments.

10. Risk Factors

The value of the fund’s shares will go up and down, sometimes rapidly or unpredictably, based on the performance of the securities owned by the fund and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund’s investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

The fund invests in lower-rated debt securities, which are subject to substantial risks including liquidity risk and credit risk.

11. Federal Tax Information

The tax character of distributions paid during the years ended May 31, 2023 and May 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Exempt income	$	28,638,734	$	27,036,886
Taxable ordinary income	—		$	615,676
Long-term capital gains	—		$	6,845,664

The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements.

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	704,038,996
Gross tax appreciation of investments	$	10,778,508
Gross tax depreciation of investments	(58,137,778)
Net tax appreciation (depreciation) of investments	(47,359,270)
Net tax appreciation (depreciation) on derivatives	—
Net tax appreciation (depreciation)	$	(47,359,270)
Other book-to-tax adjustments	$	(175,405)
Undistributed exempt income	—
Accumulated short-term capital losses	$	(25,358,611)
Accumulated long-term capital losses	$	(14,984,121)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the realization for tax purposes of unrealized gains (losses) on futures contracts.

Accumulated capital losses represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers may be carried forward for an unlimited period. Future capital loss carryover utilization in any given year may be subject to Internal Revenue Code limitations.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Municipal Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of High-Yield Municipal Fund (the “Fund”), one of the funds constituting the American Century Municipal Trust, as of May 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of High-Yield Municipal Fund of the American Century Municipal Trust, as of May 31, 2023, and the results of its operations for the year then ended and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended May 31, 2021, were audited by other auditors, whose report, dated July 21, 2021, expressed an unqualified opinion on such financial highlights.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of May 31, 2023, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Management

Board of Trustees

The individuals listed below serve as trustees of the funds. Each trustee will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for trustees who are not “interested persons,” as that term is defined in the Investment Company Act (independent trustees). Independent trustees shall retire on December 31 of the year in which they reach their 76th birthday.

Jonathan S. Thomas is an “interested person” because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). The other trustees (more than three-fourths of the total number) are independent. They are not employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM, American Century Investment Services, Inc. (ACIS) and American Century Services, LLC (ACS), and they do not have any other affiliations, positions or relationships that would cause them to be considered “interested persons” under the Investment Company Act. The trustees serve in this capacity for eight (in the case of Jonathan S. Thomas,16; and Jeremy I. Bulow, 9) registered investment companies in the American Century Investments family of funds.

The following table presents additional information about the trustees. The mailing address for each trustee other than Jonathan S. Thomas is 3945 Freedom Circle, Suite #800, Santa Clara, California 95054. The mailing address for Jonathan S. Thomas is 4500 Main Street, Kansas City, Missouri 64111.

Liquidity Risk Management Program

The Fund has adopted a liquidity risk management program (the “program”). The Fund’s Board of Trustees (the "Board") has designated American Century Investment Management, Inc. (“ACIM”) as the administrator of the program. Personnel of ACIM or its affiliates, including members of ACIM’s Investment Oversight Committee who are members of ACIM’s Investment Management and Global Analytics departments, conduct the day-to-day operation of the program pursuant to the program.

Under the program, ACIM manages the Fund’s liquidity risk, which is the risk that the Fund could not meet shareholder redemption requests without significant dilution of remaining shareholders’ interests in the Fund. This risk is managed by monitoring the degree of liquidity of the Fund’s investments, limiting the amount of the Fund’s illiquid investments, and utilizing various risk management tools and facilities available to the Fund for meeting shareholder redemptions, among other means. ACIM’s process of determining the degree of liquidity of certain investments held by the Fund is supported by a third-party liquidity assessment vendor.

The Board reviewed a report prepared by ACIM regarding the operation and effectiveness of the program for the period January 1, 2022 through December 31, 2022. No significant liquidity events impacting the Fund were noted in the report. In addition, ACIM provided its assessment that the program had been effective in managing the Fund’s liquidity risk.


Additional Information

Retirement Account Information

As required by law, distributions you receive from certain retirement accounts are subject to federal income tax withholding at the IRS default rate of 10%.* Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld.

You may elect a different withholding rate, or request zero withholding, by submitting an acceptable IRS Form W-4R election with your distribution request. You may notify us of your W-4R election by telephone, on our distribution forms, on IRS Form W-4R, or through other acceptable electronic means. If your withholding election is for an automatic withdrawal plan, you have the right to revoke your election at any time and any election you make will remain in effect until revoked by filing a new election.

Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don’t have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. You can reduce or defer the income tax on a distribution by directly or indirectly rolling such distribution over to another IRA or eligible plan. You should consult your tax advisor for additional information.

State tax will be withheld according to state regulations if, at the time of your distribution, your tax residency is within one of the mandatory withholding states.

*Some 403(b), 457 and qualified retirement plan distributions may be subject to 20% mandatory withholding, as they are subject to special tax and withholding rules. Your plan administrator or plan sponsor is required to provide you with a special tax notice explaining those rules at the time you request a distribution. If applicable, federal and/or state taxes may be withheld from your distribution amount.

Portfolio Commentary

Portfolio Managers: Alan Kruss and Joseph Gotelli

Performance Summary

Intermediate-Term Tax-Free Bond returned 0.08%* for the 12 months ended May 31, 2023. By comparison, the S&P Intermediate Term National AMT-Free Municipal Bond Index returned 1.15%. Fund returns reflect operating expenses, while index returns do not.

Second-Half Recovery Pushed Returns into Positive Territory

Municipal bonds (munis) demonstrated wide performance swings in the reporting period, with gains in the second half more than offsetting losses in the first half. Similar to all fixed-income sectors, municipal bonds struggled in 2022. Against a backdrop of surging inflation, rising interest rates, hawkish Federal Reserve (Fed) policy and widespread market volatility, munis and other bonds generally declined. Record outflows from the asset class also weighed on the muni sector.

Investment-grade munis ended the 12-month period with a modest gain, outperforming the broad U.S. Treasury index, which declined. Amid broad risk aversion, high-yield munis underperformed investment-grade munis.

Sector Allocation, Security Selection Detracted from Relative Results

Sector allocation represented the largest relative detractor for the period, mostly due to our out-of-index position in retirement communities. Out-of-index positions in student housing and multifamily housing bonds also modestly detracted.

From a security selection perspective, our choices in the special tax and public university sectors largely accounted for the lagging relative results. These effects more than offset positive security selection results from state general obligation bonds.

6. Fair Value Measurements

•Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

•Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

The following is a summary of the level classifications as of period end. The Schedule of Investments provides additional information on the fund's portfolio holdings.

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. A fund may purchase futures contracts to gain exposure to increases in market value or sell futures contracts to protect against a decline in market value. Upon entering into a futures contract, a fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. A fund may incur charges or earn income on cash deposit balances, which are reflected in interest expenses or interest income, respectively. Subsequent payments (variation margin) are made or received daily, in cash, by a fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. A fund recognizes a realized gain or loss when the futures contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of net realized gain (loss) on futures contract transactions and change in net unrealized appreciation (depreciation) on futures contracts, respectively. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. The fund's average notional exposure to interest rate risk derivative instruments held during the period was $117,321,627 futures contracts purchased and $31,097,063 futures contracts sold.

The value of interest rate risk derivative instruments as of May 31, 2023, is disclosed on the Statement of Assets and Liabilities as an asset of $697,375 in receivable for variation margin on futures contracts.* For the year ended May 31, 2023, the effect of interest rate risk derivative instruments on the Statement of Operations was $(7,370,564) in net realized gain (loss) on futures contract transactions and $1,850,398 in change in net unrealized appreciation (depreciation) on futures contracts.

*Included in the unrealized appreciation (depreciation) on futures contracts as reported in the Schedule of Investments.

8. Risk Factors

fund’s investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

The fund may invest in instruments that have variable or floating coupon rates based on the London Interbank Offered Rate (LIBOR). LIBOR is a benchmark interest rate intended to be representative of the rate at which certain major international banks lend to one another over short-terms. Financial institutions have started the process of phasing out LIBOR and the transition process to a replacement rate may lead to increased volatility or illiquidity in markets for instruments that rely on LIBOR. This could result in a change to the value of such instruments or a change in the cost of temporary borrowing for the fund.

9. Federal Tax Information

The tax character of distributions paid during the years ended May 31, 2023 and May 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Exempt income	$	111,966,207	$	97,079,869
Ordinary income	—		—
Long-term capital gains	—		—

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	3,757,273,198
Gross tax appreciation of investments	$	37,916,210
Gross tax depreciation of investments	(90,559,109)
Net tax appreciation (depreciation) of investments	(52,642,899)
Net tax appreciation (depreciation) on derivatives	—
Net tax appreciation (depreciation)	$	(52,642,899)
Other book-to-tax adjustments	$	(40)
Undistributed exempt income	—
Accumulated short-term capital losses	$	(60,918,248)
Accumulated long-term capital losses	$	(65,329,043)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the realization for tax purposes of unrealized gains (losses) on futures contracts.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Municipal Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Intermediate-Term Tax-Free Bond Fund (the “Fund”), one of the funds constituting the American Century Municipal Trust, as of May 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of Intermediate-Term Tax-Free Bond Fund of the American Century Municipal Trust, as of May 31, 2023, and the results of its operations for the year then ended and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended May 31, 2021, were audited by other auditors, whose report, dated July 21, 2021, expressed an unqualified opinion on such financial highlights.

You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

The 7-day current yield more closely reflects the current earnings of the fund than the total return.

Notes to Financial Statements

MAY 31, 2023

1. Organization

American Century Municipal Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Tax-Free Money Market Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek safety of principal and high current income that is exempt from federal income tax.

2. Significant Accounting Policies

Investment Valuations — The fund determines the fair value of its investments and computes its net asset value (NAV) per share at the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. The value of investments of the fund is determined by American Century Investment Management, Inc. (ACIM) (the investment advisor), as the valuation designee, pursuant to its valuation policies and procedures. The Board of Trustees oversees the valuation designee and reviews its valuation policies and procedures at least annually. Investments are generally valued at amortized cost, which approximates fair value. If the valuation designee determines that the valuation methods do not reflect an investment’s fair value, such investment is valued as determined in good faith by the valuation designee.

Investment Income — Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums.

Distributions to Shareholders — Distributions from net investment income, if any, are declared daily and paid monthly. The fund may make capital gains distributions to comply with the distribution requirements of the Internal Revenue Code.

3. Fees and Transactions with Related Parties

Certain officers and trustees of the trust are also officers and/or directors of American Century Companies, Inc. (ACC). The trust's investment advisor, ACIM, the trust's distributor, American Century Investment Services, Inc., and the trust's transfer agent, American Century Services, LLC, are wholly owned, directly or indirectly, by ACC.

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee). The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), and extraordinary expenses. The fee is computed and accrued daily based on the daily net assets of the fund and paid monthly in arrears. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. In order to maintain a positive yield, ACIM may voluntarily waive a portion of the management fee on a daily basis. The fee waiver may be revised or terminated at any time by the investment advisor without notice. The rates for the Investment Category Fee range from 0.1570% to 0.2700% and the rates for the Complex Fee range from 0.2500% to 0.3100%. The effective annual management fee for the period ended May 31, 2023 was 0.49%.

Interfund Transactions — The fund may enter into security transactions with other American Century Investments funds and other client accounts of the investment advisor, in accordance with the 1940 Act rules and procedures adopted by the Board of Trustees. The rules and procedures require, among other things, that these transactions be effected at the independent current market price of the security. During the period, the interfund purchases and sales were $11,575,000 and $28,769,996, respectively. The effect of interfund transactions on the Statement of Operations was $(4) in net realized gain (loss) on investment transactions.

4. Fair Value Measurements

•Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

•Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

As of period end, the fund’s investment securities were classified as Level 2. The Schedule of Investments provides additional information on the fund’s portfolio holdings.

5. Federal Tax Information

The tax character of distributions paid during the years ended May 31, 2023 and May 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Exempt income	$	3,068,709	$	55,992
Long-term capital gains	—		—

As of May 31, 2023, the fund had accumulated short-term capital losses of $(23), which represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers may be carried forward for an unlimited period. Future capital loss carryover utilization in any given year may be subject to Internal Revenue Code limitations.
