Municipal bonds are issued by states, cities, and counties, (the municipal issuer) to raise funds. The methods and traces of issuing debt are governed by an extensive system of laws and regulations, which vary by state. Bonds bear interest at either a fixed or variable rate of interest, which can be subject to a cap known as the maximum legal limit. If a bond measure is proposed in a local county election, a Tax Rate Statement may be provided to voters, detailing best estimates of the tax rate required to levy and fund the bond.
