Performance review

For the six months ended January 31, 2024, Class A shares of Western Asset Municipal High Income Fund, excluding sales charges, returned 4.25%. The Fund’s unmanaged benchmark, the Bloomberg Municipal Bond Indexⁱ, returned 2.70% for the same period.

Certain investors may be subject to the federal alternative minimum tax, and state and local taxes will apply. Capital gains, if any, are fully taxable. Please consult your personal tax or legal adviser.

Performance Snapshot as of January 31, 2024 (unaudited)
(excluding sales charges)	6 months
Western Asset Municipal High Income Fund:
Class A		4.25	%
Class C		3.88	%
Class I		4.27	%
Bloomberg Municipal Bond Index		2.70	%

The performance shown represents past performance. Past performance is no guarantee of future results and current performance may be higher or lower than the performance shown above. Principal value, investment returns and yields will fluctuate and investors’ shares, when redeemed, may be worth more or less than their original cost. To obtain performance data current to the most recent month-end, please visit our website at www.franklintempleton.com.

All share class returns assume the reinvestment of all distributions, including returns of capital, if any, at net asset value and the deduction of all Fund expenses. Returns have not been adjusted to include sales charges that may apply or the deduction of taxes that a shareholder would pay on Fund distributions. If sales charges were reflected, the performance quoted would be lower. Performance figures for periods shorter than one year represent cumulative figures and are not annualized.

Fund performance figures reflect fee waivers and/or expense reimbursements, without which the performance would have been lower.

The 30-Day SEC Yields for the period ended January 31, 2024 for Class A, Class C and Class I shares were 3.77%, 3.35% and 4.09%, respectively. Absent fee waivers and/or expense reimbursements, the 30-Day SEC Yield for Class I shares would have been 4.04%. The 30-Day SEC Yield, calculated pursuant to the standard SEC formula, is based on the Fund’s investments over an annualized trailing 30-day period, and not on the distributions paid by the Fund, which may differ.

Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated December 1, 2023, the gross total annual fund operating expense ratios for Class A, Class C and Class I shares were 0.77%, 1.33% and 0.64%, respectively.

Actual expenses may be higher. For example, expenses may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile.

As a result of an expense limitation arrangement, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses,

  IV   Western Asset Municipal High Income Fund  

Performance review (cont’d)

to average net assets will not exceed 0.55% for Class I shares. This expense limitation arrangement cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent.

The manager is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which the manager earned the fee or incurred the expense if the class’ total annual fund operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will the manager recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.

As always, thank you for your confidence in our stewardship of your assets.

Sincerely,

Jane Trust, CFA

President and Chief Executive Officer

RISKS: The Fund’s investments are subject to interest rate and credit risks. As interest rates rise, bond prices fall, reducing the value of the Fund’s share price. Municipal securities purchased by the Fund may be adversely affected by changes in the financial condition of municipal issuers and insurers, regulatory and political developments, uncertainties and public perceptions, and other factors. A significant portion of portfolio holdings may be invested in lower quality securities, which present greater risk of loss of principal and interest than higher rated securities. The Fund may enter into tender option bond (“TOB”) transactions, which expose the Fund to leverage and credit risk, and generally involve greater risk than investments in fixed rate municipal bonds, including the risk of loss of principal. The interest payments that the Fund would typically receive on inverse floaters acquired in such transactions vary inversely with short-term interest rates and will be reduced (and potentially eliminated) when short-term interest rates increase. Inverse floaters will generally underperform the market for fixed rate municipal securities when interest rates rise. The value and market for inverse floaters can be volatile, and inverse floaters can have limited liquidity. Investments in inverse floaters issued in TOB transactions are derivative instruments and, therefore, are also subject to the risks generally applicable to investments in derivatives. Below investment grade securities (that is, securities rated below the Baa/BBB categories) or, if unrated, securities determined to be of comparable credit quality are commonly referred to as “junk bonds”. Investing in securities issued by investment companies, including exchange-traded funds (“ETFs”), involves risks similar to those of investing directly in the securities and other assets held by the investment company or ETF. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs. In addition, the Fund will indirectly bear its pro rata share of the fees and

Western Asset Municipal High Income Fund     V  

expenses incurred by a fund it invests in, including advisory fees. These expenses are in addition to the advisory and other expenses that the Fund bears directly in connection with its own operations. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and may have a potentially large impact on Fund performance. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Please see the Fund’s prospectus for a more complete discussion of these and other risks and the Fund’s investment strategies.

All investments are subject to risk including the possible loss of principal. Past performance is no guarantee of future results. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

i The Bloomberg Municipal Bond Index is a market value weighted index of investment grade municipal bonds with maturities of one year or more.

Fund expenses (unaudited)

Example

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

This example is based on an investment of $1,000 invested on August 1, 2023 and held for the six months ended January 31, 2024.

Actual expenses

The table below titled “Based on actual total return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period”.

Hypothetical example for comparison purposes

The table below titled “Based on hypothetical total return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or back-end sales charges (loads). 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 transaction costs were included, your costs would have been higher.

  2   Western Asset Municipal High Income Fund 2024 Semi-Annual Report  

¹  For the six months ended January 31, 2024.

²  Assumes the reinvestment of all distributions, including returns of capital, if any, at net asset value and does not reflect the deduction of the applicable sales charge with respect to Class A shares or the applicable contingent deferred sales charge (“CDSC”) with respect to Class C shares. Total return is not annualized, as it may not be representative of the total return for the year. Performance figures may reflect compensating balance arrangements, fee waivers and/or expense reimbursements. In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower. Past performance is no guarantee of future results.

³  Expenses (net of compensating balance arrangements, fee waivers and/or expense reimbursements) are equal to each class’ respective annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year (184), then divided by 366.

These securities do not indicate a reference rate and spread in their description above.

^(c)  Income from this issue is considered a preference item for purposes of calculating the alternative minimum tax (“AMT”).

^(d)  Security is exempt from registration under Rule 144A of the Securities Act of 1933.

VRDOs are benchmarked to the Securities Industry and Financial Markets Association (“SIFMA”) Municipal Swap Index.

1. Organization and significant accounting policies

Western Asset Municipal High Income Fund (the “Fund”) is a separate diversified investment series of Legg Mason Partners Income Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company.

The Fund follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (“ASC 946”). The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”), including, but not limited to, ASC 946. Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services typically use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Trustees.

Pursuant to policies adopted by the Board of Trustees, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’s manager is assisted by the Global Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to

Western Asset Municipal High Income Fund 2024 Semi-Annual Report   27

Notes to financial statements (unaudited) (cont’d)

the Fund’s manager and the Board of Trustees. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Trustees, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Trustees quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

• Level 1 — unadjusted quoted prices in active markets for identical investments

• Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

  28 Western Asset Municipal High Income Fund 2024 Semi-Annual Report

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets carried at fair value:

† See Schedule of Investments for additional detailed categorizations.

†† Reflects the unrealized appreciation (depreciation) of the instruments.

(b) Tender option bonds. The Fund may enter into tender option bond (“TOB”) transactions and may invest in inverse floating rate instruments (“Inverse Floaters”) issued in TOB transactions. The Fund may participate either in structuring an Inverse Floater or purchasing an Inverse Floater in the secondary market. When structuring an Inverse Floater, the Fund deposits securities (typically municipal bonds or other municipal securities) (the “Underlying Bonds”) into a special purpose entity, referred to as a TOB trust. The TOB trust generally issues floating rate notes (“Floaters”) to third parties and residual interest, Inverse Floaters, to the Fund. The Floaters issued by the TOB trust have interest rates which reset weekly and provide the holders of the Floaters the option to tender their notes back to the TOB trust for redemption at par at each reset date. The net proceeds of the sale of the Floaters, after expenses, are received by the Fund and may be invested in additional securities. The Inverse Floaters are inverse floating rate debt instruments, as the return on those bonds is inversely related to changes in a specified interest rate. Distributions on any Inverse Floaters paid to the Fund will be reduced or, in the extreme, eliminated as short-term interest rates rise and will increase when such interest rates fall. Floaters issued by a TOB trust may be senior to the Inverse Floaters held by the Fund. The value and market for Inverse Floaters can be volatile, and Inverse Floaters can have limited liquidity.

An investment in an Inverse Floater structured by the Fund is accounted for as a secured borrowing. The Underlying Bonds deposited into the TOB trust are included in the Fund’s Schedule of Investments and a liability for Floaters (TOB floating rate notes) issued by the

Western Asset Municipal High Income Fund 2024 Semi-Annual Report   29

Notes to financial statements (unaudited) (cont’d)

TOB trust is recognized in the Fund’s Statement of Assets and Liabilities. The carrying amount of the TOB trust’s floating rate note obligations as reported on the Statement of Assets and Liabilities approximates its fair value. Interest income, including amortization, on the Underlying Bonds is recognized in the Fund’s Statements of Operations. Interest paid to holders of the Floaters, as well as other expenses related to administration, liquidity, remarketing and trustee services of the TOB trust, are recognized in Interest expense in the Fund’s Statement of Operations. For the six months ended January 31, 2024, the average daily amount of floating rate notes outstanding was $5,460,652 and weighted average interest rate was 4.09%.

(c) Futures contracts. The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the Fund is required to deposit cash or securities with a broker in an amount equal to a certain percentage of the contract amount. This is known as the ‘‘initial margin’’ and subsequent payments (‘‘variation margin’’) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. For certain futures, including foreign denominated futures, variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. The daily changes in contract value are recorded as unrealized appreciation or depreciation in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(d) Credit and market risk. The Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading.

(e) Counterparty risk and credit-risk-related contingent features of derivative instruments. The Fund may invest in certain securities or engage in other transactions where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s subadviser attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or

  30 Western Asset Municipal High Income Fund 2024 Semi-Annual Report

limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter (“OTC”) derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or net asset value per share over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific for OTC traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

As of January 31, 2024, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

Western Asset Municipal High Income Fund 2024 Semi-Annual Report   31

Notes to financial statements (unaudited) (cont’d)

(f) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities, which are amortized to the earliest call date. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(g) Distributions to shareholders. Distributions from net investment income of the Fund are declared each business day to shareholders of record and are paid monthly. The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from federal and certain state income taxes, to retain such tax-exempt status when distributed to the shareholders of the Fund. Distributions of net realized gains, if any, are taxable and declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(h) Share class accounting. Investment income, common expenses and realized/ unrealized gains (losses) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that share class.

(i) Compensating balance arrangements. The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.

(j) Federal and other taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of July 31, 2023, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

  32 Western Asset Municipal High Income Fund 2024 Semi-Annual Report

(k) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share.

2. Investment management agreement and other transactions with affiliates

Franklin Templeton Fund Adviser, LLC (“FTFA”) (formerly known as Legg Mason Partners Fund Advisor, LLC prior to November 30, 2023) is the Fund’s investment manager and Western Asset Management Company, LLC (“Western Asset”) is the Fund’s subadviser. FTFA and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.45% of the Fund’s daily net assets.

FTFA provides administrative and certain oversight services to the Fund. FTFA delegates to the subadviser the day-to-day portfolio management of the Fund. For its services, FTFA pays Western Asset a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund.

As a result of an expense limitation arrangement between the Fund and FTFA, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Class I shares did not exceed 0.55%. Total annual fund operating expenses, after waiving and/or reimbursing expenses, exceeded the expense limitation for Class I shares as a result of interest expense. This expense limitation arrangement cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent.

During the six months ended January 31, 2024, fees waived and/or expenses reimbursed amounted to $29,201.

FTFA is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which FTFA earned the fee or incurred the expense if the class’ total annual fund operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will FTFA recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.

Western Asset Municipal High Income Fund 2024 Semi-Annual Report   33

Notes to financial statements (unaudited) (cont’d)

Pursuant to these arrangements, at January 31, 2024, the Fund had remaining fee waivers and/or expense reimbursements subject to recapture by FTFA and respective dates of expiration as follows:

	Class A		Class C		Class I
Expires July 31, 2024		—		—	$	67,436
Expires July 31, 2025	$	357	$	16		52,327
Expires July 31, 2026		—		—		29,201
Total fee waivers/expense reimbursements subject to recapture	$	357	$	16	$	148,964

For the six months ended January 31, 2024, FTFA did not recapture any fees.

Franklin Distributors, LLC (“Franklin Distributors”) serves as the Fund’s sole and exclusive distributor. Franklin Distributors is an indirect, wholly-owned broker-dealer subsidiary of Franklin Resources. Franklin Templeton Investor Services, LLC (“Investor Services”) serves as the Fund’s shareholder servicing agent and acts as the Fund’s transfer agent and dividend-paying agent. Investor Services is an indirect, wholly-owned subsidiary of Franklin Resources. Each class of shares of the Fund pays transfer agent fees to Investor Services for its performance of shareholder servicing obligations. Investor Services charges account-based fees based on the number of individual shareholder accounts, as well as a fixed percentage fee based on the total account-based fees charged. In addition, each class reimburses Investor Services for out of pocket expenses incurred. For the six months ended January 31, 2024, the Fund incurred transfer agent fees as reported on the Statement of Operations, of which $792 was earned by Investor Services.

There is a maximum initial sales charge of 3.75% for Class A shares. There is a contingent deferred sales charge (“CDSC”) of 1.00% on Class C shares, which applies if redemption occurs within 12 months from purchase payment. In certain cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs within 18 months from purchase payment. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of other shares of funds sold by Franklin Distributors, equal or exceed $250,000 in the aggregate. These purchases do not incur an initial sales charge.

For the six months ended January 31, 2024, sales charges retained by and CDSCs paid to Franklin Distributors and its affiliates, if any, were as follows:

	Class A
Sales charges	$	1,871
CDSCs		886

All officers and one Trustee of the Trust are employees of Franklin Resources or its affiliates and do not receive compensation from the Trust.

The Fund is permitted to purchase or sell short-term variable rate demand obligations from or to certain other affiliated funds or portfolios under specified conditions outlined in procedures adopted by the Board of Trustees. The procedures have been designed to

  34 Western Asset Municipal High Income Fund 2024 Semi-Annual Report

provide assurance that any purchase or sale of securities by the Fund from or to another fund or portfolio that is, or could be considered, an affiliate by virtue of having a common investment manager or subadviser (or affiliated investment manager or subadviser), common Trustees and/or common officers complies with Rule 17a-7 under the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. For the six months ended January 31, 2024, such purchase and sale transactions (excluding accrued interest) were $28,770,000 and $19,070,000, respectively.

8. Redemption facility

The Fund, together with other U.S. registered and foreign investment funds (collectively, the “Borrowers”) managed by Franklin Resources or its affiliates, is a borrower in a joint syndicated senior unsecured credit facility totaling $2.675 billion (the “Global Credit Facility”). The Global Credit Facility provides a source of funds to the Borrowers for temporary and emergency purposes, including the ability to meet future unanticipated or unusually large redemption requests. Unless renewed, the Global Credit Facility will terminate on January 31, 2025.

Under the terms of the Global Credit Facility, the Fund shall, in addition to interest charged on any borrowings made by the Fund and other costs incurred by the Fund, pay its share of fees and expenses incurred in connection with the implementation and maintenance of the Global Credit Facility, based upon its relative share of the aggregate net assets of all the Borrowers, including an annual commitment fee of 0.15% based upon the unused portion of the Global Credit Facility.
