Municipal Bonds
The plain answer
Section titled “The plain answer”Municipal bonds are issued by states, cities, and other public entities. Their interest is often exempt from federal income tax. It may also be exempt from state or local income tax when you live in the issuing state, depending on that state’s rules.
That tax treatment can be valuable, but a municipal bond is not automatically better than a taxable bond. Compare what you keep after taxes, along with risk, maturity, fees, and liquidity.
How it actually works
Section titled “How it actually works”Most municipal bond interest is excluded from regular federal taxable income. Exceptions exist, and some private activity bond interest can affect the alternative minimum tax. State tax treatment varies. Interest from an out-of-state bond may be taxable by your state even when it is federally tax-exempt.
The exemption generally applies to interest, not every return from the bond. Selling a municipal bond for more than your cost can create a taxable capital gain. Bond funds can also distribute taxable gains. Review Interest Income and How Investments Are Taxed for the distinction.
What this means for you
Section titled “What this means for you”Compare a municipal bond’s after-tax yield with the after-tax yield of a taxable bond that has similar credit risk, maturity, call features, and costs. Your actual federal and state marginal tax rates matter. A lower tax rate makes the exemption less valuable, while a higher tax rate can make it more valuable.
Do not spend a dollar to save thirty cents in taxes. A lower-yielding municipal bond can leave you with less income even after its tax benefit. Start with the investment’s role in your portfolio, then evaluate taxes. Tax-Efficient Investing explains how account type also affects the decision.
Common mistakes

- Assuming every municipal bond is exempt from federal, state, and local tax
- Ignoring credit risk, call risk, maturity, fund expenses, or trading costs
- Holding municipal bonds in a tax-advantaged account where the exemption may add little value
