Understanding Tax-Exempt Municipal Bonds: Key Points
Managing taxes is unavoidable, but many investors aim to reduce their tax burden by earning tax-exempt income. Tax-free municipal bonds offer a beneficial investment option where the earned interest is exempt from federal taxes, and sometimes state and local taxes as well. These bonds provide a steady income stream with the advantage of tax-free compounding when reinvested. Typically, municipal bonds yield higher after-tax returns compared to similar taxable government or corporate bonds. Here's a overview of essential facts about tax-free municipal bonds.

What are municipal bonds?
Municipal bonds, or munis, are debt instruments issued by local or state governments to fund public projects or facilities. These include constructing hospitals, roads, bridges, or supporting community programs. Entities such as port authorities and housing agencies may also issue them. Municipal bonds offer tax-free income and allow investors to support community development while earning stable returns. Unlike corporate bonds, munis accrue tax-exempt interest, making them attractive for investors seeking tax-efficient income.
Municipal bonds tend to differ from corporate bonds in several ways.
Unlike corporate bonds, which generate taxable income, the interest from munis is usually exempt from federal, state, and local taxes if issued within the investor's residence state. Additionally, municipal bonds typically have serial maturity structures, meaning portions mature at different times until the entire principal is repaid. They are usually issued in $5,000 denominations, compared to $1,000 for corporate bonds, and often trade over-the-counter rather than on stock exchanges. Some munis include call provisions allowing early redemption if interest rates fall below the bond's coupon rate.
Not all municipal bonds are tax-exempt. Some, like private purpose bonds, may be taxable unless explicitly designated as tax-exempt. Certain muni bonds could also be subject to the alternative minimum tax (AMT).
The most common type is the General Obligation (GO) bond, backed by the issuing authority's pledge to repay, making them low-risk investments, though with lower yields. Revenue bonds, secured by designated revenue sources such as tolls or fees, generally offer higher yields but come with increased risk. Short-term municipal debt, known as commercial paper, matures in less than nine months and typically provides lower yields. Private activity bonds fund specific private projects and usually offer higher returns, though their tax-exempt status and risk level vary.
