What Is Tax-Exempt Interest?
Tax-exempt interest is interest income that is not subject to federal income tax. In some cases, the amount of tax-exempt interest a taxpayer earns can limit the taxpayer's qualification for certain other tax breaks. The most common sources of tax-exempt interest come from municipal bonds or income-producing assets inside of Roth retirement accounts.
- Tax-exempt interest refers to interest income that is not subject to taxation, most notably at the federal level.
- Some municipal bonds may also be "triple-exempt", where tax is not paid at the federal, state, nor local level.
- Tax-exempt interest may also be earned in Roth retirement accounts as well as some other tax-advantaged products and accounts.
Tax-Exempt Interest Explained
Tax-exempt interest can be somewhat of a misnomer as it may still be taxed at the state or local levels. It may also be subject to the alternative minimum tax (AMT). Furthermore, capital gains on tax-exempt investments are still taxable; only the interest on these investments is tax-exempt. The most common way to earn interest that is tax-exempt at the state and local levels in addition to the federal level is for an investor to purchase a municipal bond issued in his or her state or locality of residence.
Municipal bonds are one of the most common types of investments that pay tax-exempt interest, but while interest may be tax-exempt at the federal level it may still be taxed at the state level. For example, a California resident who buys a New York municipal bond would pay California income tax on that interest. These tax laws, however, vary by state. For instance, some states such as Wisconsin and Illinois tax interest earned on most muni bonds, including their own, while states such as California and Arizona exempt interest from taxes if the investor resides in their states. Utah is an example of a state that exempts interest on out-of-state bonds, as long as that state does not impose a tax on bonds issued by Utah. Treasury securities issued by the U.S. government pay interest that is tax exempt at the state and local levels, but not the federal level.
Triple-tax-exempt is a way of describing an investment, usually a municipal bond, which features interest payments exempt from taxes at the municipal, state and federal levels.
State and Local Taxation of Interest
According to the Internal Revenue Service (IRS), interest on a state or local government obligation may be tax-exempt even if the obligation is not a bond. For example, interest on a debt evidenced only by an ordinary written agreement of purchase and sale may be tax-exempt. Also, interest paid by an insurer on default by the state or political subdivision may be tax-exempt.
Mutual funds that hold a mix of stocks and municipal bonds will have the portion of earnings derived from the bonds tax-exempt under federal income tax guidelines and possibly exempt from state taxes depending on the location from which the bonds originated and/or the taxpayer's state of residence.
Since tax-exempt interest is not subject to income taxes, it is not included in the calculation of adjusted gross income (AGI) for taxation purposes. Issuers or lenders that pay more than $10 in tax-exempt interest must report the interest income to both taxpayers and the IRS on Form 1099-INT. Taxpayers or borrowers, in turn, must report this tax-exempt interest on Form 1040. The amount received as tax-exempt interest is used by the IRS to determine what amount of the taxpayer’s Social Security benefits is taxable.
