What is a Municipal Bond?

A municipal bond is a bond issued by a city or other local government, or their agencies. Potential issuers of municipal bonds include cities, counties, redevelopment agencies, special-purpose districts, school districts, public utility districts, publicly owned airports and seaports, and any other governmental entity (or group of governments) below the state level.

Municipal bonds may be general obligations of the issuer or secured by specified revenues. Interest income received by holders of municipal bonds is often exempt from the federal income tax and from the income tax of the state in which they are issued, although municipal bonds issued for certain purposes may not be tax exempt.

When you purchase a municipal bond, you are lending money to a state or local government entity, which in turn promises to pay you a specified amount of interest (usually paid semiannually) and return the principal to you on a specific maturity date.

Not all municipal bonds offer income exempt from both federal and state taxes. There is an entirely separate market of municipal issues that are taxable at the federal level, but still offer a state—and often local—tax exemption on interest paid to residents of the state of issuance.

Municipal bonds (also known as “munis”) are attractive to many investors because the interest income is exempt from federal income tax, and in many cases, state and local taxes as well. In addition, munis often represent investments in state and local government projects that have an impact on our daily lives, including schools, highways, hospitals, housing, sewer systems and other important public projects.

Because of the special tax-exempt status of most municipal bonds, investors usually accept lower interest payments than on other types of borrowing (assuming comparable risk). This makes the issuance of bonds an attractive source of financing to many municipal entities, as the borrowing rate available in the open market is frequently lower than what is available through other borrowing channels.
