What type of bonds are exempt from federal, state, and local taxation?

Triple-Tax Exempt Bonds are significant because they provide investors with the benefit of being exempt from federal, state, and local taxes. These types of bonds are usually issued by certain governments or governmental agencies, particularly in the case of specific types of municipal bonds that fulfill certain criteria.

The appeal of these bonds lies in their tax advantages, which can lead to higher effective yields for investors in higher tax brackets. By being exempt from taxation at all three levels, they can be especially attractive for those seeking to minimize their tax liability while investing.

In contrast, while municipal bonds can often be tax-exempt at the federal level and sometimes at the state and local levels depending on the issuer and the investor's state of residence, they do not necessarily cover all three types of taxation for every holder. Corporate bonds are subject to federal and state taxation, and savings bonds, while they may offer certain tax benefits under specific conditions, do not carry the comprehensive tax exemption that triple-tax exempt bonds provide.
