Municipal bonds are usually not taxed at the federal level, but state and local taxes depend on where you live and where the bond is issued
The main tax advantage of municipal bonds is that the interest you earn is almost always exempt from federal income tax. That means if a municipal bond pays you $1,000 in interest, you do not report that $1,000 as income on your federal tax return. This is different from Treasury bonds, corporate bonds, and savings accounts, where all interest is taxable federally.
However, the state and local tax picture is more complicated. Some states tax municipal bond interest, some do not, and some only tax bonds issued outside their borders. Whether you pay state or local tax on a municipal bond depends on three things: your state's tax rules, the state where the bond was issued, and sometimes the specific city or county that issued it.
Key Takeaways
- Federal income tax is not owed on interest from municipal bonds, which is the primary tax benefit.
- State income tax on municipal bond interest varies by state — some states exempt all municipal bonds, some tax all of them, and some only exempt bonds issued within that state.
- Local income taxes in cities like New York City and Washington, D.C. may explore to municipal bond interest even when state tax does not.
- The original purchase price of a municipal bond and any profit when you sell it are subject to federal and state capital gains tax.
- Your state's tax treatment of out-of-state bonds can make in-state bonds more valuable to you personally, even if they pay slightly less interest.
Federal tax exemption on municipal bond interest
When you receive interest payments from a municipal bond, that interest is not subject to federal income tax. The IRS treats municipal bond interest as tax-exempt income. You still receive the full payment, but you do not include it on your Form 1040 when you file your federal return.
This exemption applies to bonds issued by states, cities, counties, and other local governments. It does not matter whether the bond is issued in your home state or another state — the federal exemption is the same everywhere. A bond issued by the City of Chicago pays federal-tax-free interest to someone living in California, Florida, or any other state.
The one exception is that some municipal bonds are issued for private purposes and do not may have access to for tax exemption. These are called private activity bonds. Your bond statement or prospectus will tell you whether your bond qualifies for the exemption. Most bonds sold to individual investors do may have access to.
State income tax on municipal bonds
State tax treatment of municipal bonds varies significantly. Some states do not tax municipal bond interest at all, regardless of where the bond was issued. Other states tax all municipal bond interest the same way they tax other income. Still others use a hybrid approach: they exempt bonds issued within the state but tax bonds issued elsewhere.
States that do not tax municipal bond interest at all include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe no state income tax on municipal bond interest from any issuer, anywhere.
States that tax all municipal bond interest include Connecticut, Illinois, Kansas, Maine, Maryland, Missouri, Montana, New Mexico, Ohio, Oklahoma, and Vermont. If you live in one of these states, you owe state income tax on municipal bond interest just as you would on other income, regardless of where the bond was issued.
States that exempt only in-state bonds include California, Colorado, Georgia, Massachusetts, Michigan, Minnesota, Mississippi, New York, North Carolina, Oregon, Pennsylvania, and Virginia. If you live in one of these states and buy a bond issued in your state, the interest is exempt from state tax. If you buy a bond issued in another state, you owe state income tax on the interest. This rule creates a tax advantage for in-state bonds in your portfolio.
Local income taxes on municipal bonds
Some cities and counties impose local income taxes, and those taxes may explore to municipal bond interest even when your state does not. New York City, for example, taxes municipal bond interest at the local level. Washington, D.C. also taxes municipal bond interest. A handful of other cities and counties do the same.
If you live in a jurisdiction with a local income tax, check whether that tax applies to municipal bonds. Your local tax authority or the bond's prospectus can tell you. Local tax rates are typically lower than state rates, but they can still reduce the after-tax return on your bond.
Capital gains tax on municipal bonds
The tax exemption on municipal bonds covers only the interest you earn. If you buy a bond at one price and sell it at a higher price, the profit is subject to capital gains tax — both federal and state.
For example, if you buy a municipal bond for $10,000 and sell it for $10,500 six months later, the $500 gain is a short-term capital gain. You owe federal income tax on that gain at your ordinary income tax rate. You may also owe state and local capital gains tax, depending on where you live.
If you hold the bond for more than one year before selling, the gain is a long-term capital gain and is taxed at the lower federal long-term capital gains rate (0%, 15%, or 20%, depending on your income). State capital gains tax, where it exists, may use different holding periods and rates.
How to report municipal bond interest on your tax return
Even though municipal bond interest is not taxable, you still report it on your federal return. On Form 1040, there is a line for tax-exempt interest income. You enter the total amount of municipal bond interest you received during the year on that line. This does not increase your tax, but it is used to calculate certain other tax items, such as whether your Social Security benefits are taxable.
Your bond issuer or broker will send you a Form 1099-INT showing the interest you received. Use that form to fill in your tax return. Keep a copy for your records.
For state taxes, follow your state's rules. If your state exempts municipal bonds, you typically do not report the interest on your state return. If your state taxes municipal bonds, you report the interest as income on your state return, just as you would on your federal return.
Comparing after-tax returns across different bonds
The tax exemption on municipal bonds makes them more valuable than taxable bonds with the same interest rate, but the exact advantage depends on your tax bracket and where you live. A municipal bond paying 3% interest is worth more to someone in the 24% federal tax bracket than to someone in the 12% bracket, because the tax savings are larger.
If you live in a state that taxes municipal bonds, an in-state bond may be worth more to you than an out-of-state bond paying the same interest rate, because you avoid both federal and state tax on the in-state bond. A financial advisor or bond broker can help you calculate the after-tax return on different bonds to compare them fairly.
Frequently Asked Questions
Do I owe federal tax on municipal bond interest?
No. Municipal bond interest is exempt from federal income tax. You do not include it on your Form 1040 as taxable income, though you do report the amount on the tax-exempt interest line for informational purposes.
What if I live in a state that taxes municipal bonds?
You owe state income tax on the interest at your state's ordinary income tax rate. Some states exempt in-state bonds but tax out-of-state bonds, so check your state's specific rules. Your state tax return will have a line for municipal bond interest if it is taxable in your state.
Do I owe capital gains tax if I sell a municipal bond for a profit?
Yes. The tax exemption covers only interest income, not gains from selling the bond. If you sell for more than you paid, the profit is subject to federal capital gains tax and possibly state capital gains tax, depending on your state and how long you held the bond.
Are municipal bonds issued in other states taxed differently?
It depends on your state. If your state exempts only in-state bonds, then out-of-state bonds are subject to state income tax. If your state exempts all municipal bonds or taxes all of them, then the issuer's location does not matter for state tax purposes. Federal tax exemption applies to all municipal bonds regardless of where they are issued.
Do I have to report municipal bond interest on my tax return?
You report it on your federal return on the tax-exempt interest line, even though it is not taxable. This is required for informational purposes and may affect the calculation of other tax items. For state taxes, follow your state's rules — some states require you to report it, others do not.
