What Is Municipal Bond?

Municipal bonds ("munis") are debt securities issued by states, cities, counties, and other governmental entities to finance public projects such as schools, highways, hospitals, and infrastructure. Their primary attraction is tax-exempt interest: coupon payments are generally exempt from federal income tax and may also be exempt from state and local taxes if the investor resides in the issuing state. This tax advantage makes munis particularly attractive for investors in high tax brackets. General obligation (GO) bonds are backed by the full taxing power of the issuer, while revenue bonds are repaid from specific project revenues (tolls, utility fees, etc.). The municipal bond market exceeds $4 trillion in the United States.
