In the United States, a municipal bond (or muni) is a bond issued by a state, city or other local government, or their agencies. Potential issuers of municipal bonds include cities, counties, redevelopment agencies, school districts, publicly owned airports and seaports, and any other governmental entity (or group of governments) below the state level. Municipal bonds are guaranteed by a local government, a subdivision thereof, or a group of local governments, and are assessed for risk and rated accordingly. 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.
The issuer of a municipal bond receives a cash payment at the time of issuance in exchange for a promise to repay the investors who provide the cash payment (the bond holder) over time. Repayment periods can be as short as a few months (although this is rare) to 20, 30, or 40 years, or even longer.
The issuer typically uses proceeds from a bond sale to pay for projects or for other purposes it cannot or does not desire to pay for immediately with funds on hand. Tax regulations * governing municipal bonds generally require all money raised by a bond sale to be spent on one-time capital projects within three to five years of issuance. Certain exceptions permit the issuance of bonds to fund other items, including ongoing operations and maintenance expenses, the purchase of single-family and multi-family mortgages, and the funding of student loans, among many other things.
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.
Municipal bonds are one of several ways states, cities and countries can issue debt. Other mechanisms include certificates of participation and lease-buyback agreements. While these methods of borrowing differ in legal structure, they are similar to the municipal bonds described in this article.
Repayment schedules differ with the type of bond issued. The issuer may make equal amortized interest and principal payments every six months, may make only interest payments until the bond matures and then repay the entire principal amount, make one lump-sum payment at maturity, or some mix of these options.
The interest income on a municipal bond may be tax-exempt. This makes municipal bonds an attractive investment to certain investors, and results in investors accepting a lower interest rate on their investment than they would on a taxable investment of equivalent risk.
The type of project or projects that are funded by a bond affects the taxability of income received on the bonds held by bond holders. Interest earnings on bonds that fund projects that are constructed for the public good are generally exempt from federal income tax, while interest earnings on bonds issued to fund projects partly or wholly benefiting only private parties may be subject to federal income tax.
The laws governing the taxability of municipal bond income are complex; however, bonds are typically certified by a law firm as either tax-exempt (federal and/or state income tax) or taxable before they are offered to the market. Purchasers of municipal bonds should be aware that not all municipal bonds are tax-exempt.
The risk ("security") of a municipal bond is a measure of how likely the issuer is to make all payments, on time and in full, as promised in the agreement between the issuer and bond holder (the "bond documents"). Different types of bonds carry different securities, based on the promises made in the bond documents:
The probability of repayment as promised is often determined by an independent reviewer, or "rating agency". The three main rating agencies for municipal bonds in the United States are Standard & Poor's, Moody's, and Fitch. These agencies can be hired by the issuer to assign a bond rating, which is valuable information to potential bond holders that helps sell bonds on the primary market.
Because municipal bonds are most often tax-exempt, comparing the coupon rates of municipal bonds to corporate or other taxable bonds can be misleading. Taxes reduce the net income on taxable bonds, meaning that a tax-exempt municipal bond has a higher after-tax yield than a corporate bond with the same coupon rate.
This relationship can be demonstrated mathematically, as follows:
rm = rc ( 1 - t )
where rm = interest rate of municipal bond rc = interest rate of comparable corporate bond t = tax rate
For example if: rc = 10% t = 38% then rm = .10 (1 - .38) = 6.2%
A municipal bond that pays 6.2% therefore generates equal interest income after taxes as a corporate bond that pays 10% (assuming all else is equal).
