Tax-Exempt Interest


Tax-exempt interest is the income earned from certain investments that are not subject to federal income tax and, in some cases, state and local taxes. It is commonly associated with municipal bonds, which are issued by local and state governments for financing public projects. This tax exemption makes these investments attractive to investors, especially those in higher tax brackets, as it can offer them a higher after-tax return.


The phonetic pronunciation of “Tax-Exempt Interest” is: tæks ɪɡˈzɛmpt ˈɪntrəst

Key Takeaways

  1. Tax-exempt interest is interest income earned from investments that are exempt from federal income tax, and often also exempt from state and local taxes, making it more attractive for investors seeking tax-efficient income.
  2. Typically, tax-exempt interest income comes from investments in municipal bonds issued by state, local, and municipal governments or their agencies. These bonds are often used to fund public projects, such as infrastructure improvements and education.
  3. Though tax-exempt interest income offers significant tax advantages, it may not always provide the highest overall return compared to similar taxable investments. Investors should carefully consider their specific tax situation and investment goals before investing in tax-exempt securities.


Tax-exempt interest is an important concept in business and finance because it refers to the interest earned on certain financial instruments, such as municipal bonds, that is not subject to federal income tax, and, in some cases, state and local taxes. This tax advantage makes these financial products particularly attractive to investors, especially those in higher tax brackets, as it effectively increases the after-tax yield on their investments. Consequently, tax-exempt interest not only fosters greater investment in public projects funded by municipal bonds, but it also encourages individuals and organizations to allocate capital more efficiently, promoting overall economic growth and development.


Tax-exempt interest serves a crucial purpose in the financial landscape by encouraging investment in particular sectors of the economy, often in areas deemed essential for the growth and development of communities. Typically, this form of interest is derived from investments in debt securities, such as municipal bonds, which are issued by local or state government entities to fund various public projects such as infrastructure, education, and healthcare facilities. The main advantage of tax-exempt interest lies in its favorable tax treatment, as a means to incentivize investors to engage in funding projects that contribute to the overall well-being and advancement of society.

The utilization of tax-exempt interest benefits both investors and the issuing entities. For investors, earning interest that is exempt from federal taxes – and in some cases, state and local taxes as well – enables them to preserve more of their investment income, making these debt securities an attractive option, particularly for those in higher tax brackets. On the other hand, the issuers benefit from a wider investor base, consisting not only of high-net-worth individuals but also institutions, mutual funds, and trusts, ultimately reducing their borrowing costs.

Therefore, tax-exempt interest serves as a valuable tool in fostering investments that support vital public services, enabling governments to access the capital necessary to meet their communities’ needs while providing investors a tax-efficient means to grow their portfolios.


1. Municipal Bonds: One of the most common examples of tax-exempt interest is the interest earned from municipal bonds. These bonds are issued by state or local governments to fund public projects, such as building schools or highways. The interest paid on these bonds is generally exempt from federal income tax and, in some cases, from state and local taxes as well, especially if the investor resides in the state issuing the bond.

2. U.S. Treasury Securities: Interest earned on certain U.S. Treasury securities, like Treasury bills, notes, and bonds, is exempt from state and local income taxes. Although the interest earned on these securities is subject to federal income tax, it offers a tax advantage to investors who reside in states with higher state and local income tax rates.

3. 529 College Savings Plans: A 529 plan is a tax-advantaged investment plan designed to encourage saving for future education costs. The plans are sponsored by states or educational institutions. Although the contributions to a 529 plan are not tax-deductible, the earnings from the investments in the plan grow tax-free, and the withdrawals used for qualified education expenses are also exempt from federal income tax and, in most cases, state tax. This exemption makes the interest earned from 529 plans another example of tax-exempt interest.
