Is municipal bond interest taxable?

The short answer, and what it depends on

Interest on bonds issued by states, cities, counties and other local government bodies is the classic example of tax-exempt income. Publication 550 states the rule in one sentence: interest you receive on an obligation issued by a state or local government generally is not taxable, and the issuer should be able to tell you whether it is, with a periodic or year-end statement. If you invest through a fund or trust, that organization should give you the information. The word “generally” is carrying a lot, so this page goes through what qualifies, what does not, and what you still owe.

Who counts as a government issuer

The publication says interest on a bond used to finance government operations generally is not taxable if the bond is issued by a state, the District of Columbia, a U.S. territory, or any of their political subdivisions. Political subdivisions can include port authorities, toll road commissions, utility service authorities, community redevelopment agencies, and qualified volunteer fire departments for certain obligations issued after 1980. Bonds issued by an Indian tribal government after 1982 are treated as issued by a state in many cases. Debts that are not bonds can qualify too: interest on a debt evidenced only by an ordinary written agreement of purchase and sale may be tax exempt.

When municipal interest is taxable

The publication lists the cases in which interest on a state or local obligation is taxable:

• Private activity bonds that are not qualified bonds. A private activity bond generally has more than 10% of proceeds used for private business and more than 10% of payments secured by or derived from that business use. Interest on a private activity bond is tax exempt only if it is a qualified bond, such as an exempt-facility bond or a qualified student loan bond.
• Arbitrage bonds issued after October 9, 1969, where proceeds are expected to be used to buy higher-yielding investments.
• Federally guaranteed bonds issued after 1983, subject to listed agency exceptions such as the Department of Veterans Affairs and the Federal Housing Administration.
• Mortgage revenue bonds issued after April 24, 1979, unless they are qualified mortgage bonds or qualified veterans’ mortgage bonds.
• Unregistered bonds. A bond issued after June 30, 1983 generally must be in registered form for its interest to be tax exempt.
• Tax credit bonds such as Build America Bonds, where the holder claims a credit on Form 8912 instead of excluding interest.

What you must still report

Exempt does not mean invisible. If you must file a return, the publication requires you to show tax-exempt interest. You add interest from Form 1099-INT box 8, accrued original issue discount from Form 1099-OID box 11, and exempt-interest dividends from a mutual fund (Form 1099-DIV box 12), and report the total on Form 1040 or 1040-SR, line 2a. The publication stresses that this is an information reporting requirement only and does not turn the interest into taxable interest. Interest from an IRA is not tax-exempt interest and must not be included.

Interest on certain private activity bonds issued after August 7, 1986 can be a tax preference item subject to the alternative minimum tax. Form 1099-INT box 9 and Form 1099-DIV box 13 show the AMT portion, which is already included in the boxes 8 and 12 totals; do not add it again.

Selling a municipal bond

The publication includes a caution: even if the interest is exempt, you may have to report a capital gain or loss when you sell the bond. Interest accrued to the date you sell is part of the price, and the rest is a gain or loss against your basis. Estate, gift or generation-skipping tax may also apply to other transfers.

Is a municipal bond worth it? A comparison

The tax-exempt yield matters only against the yield you would earn on a taxable bond, after tax. To compare, divide the tax-exempt yield by one minus your marginal rate. A 3.5% municipal yield for someone in the 24% federal bracket is equivalent to a taxable yield of 3.5 divided by 0.76, about 4.61%. A taxable bond must pay more than that to leave you better off, before considering state tax, credit quality and AMT. The calculator above does this arithmetic; enter your marginal rate from your latest return or from the federal tax brackets page. This is simple algebra and is not drawn from the publication, which does not give a yield comparison.

Limits of this page

This page covers federal income tax on interest received by an individual. State income tax treatment varies and is not covered by Publication 550. Bond premium on tax-exempt bonds must be amortized, and the amortization reduces your basis but is not deductible. For yield mechanics see the bond yield calculator.
