Reciprocal tax agreements allow residents of one state to work in another state without having income taxes withheld in the state they work in. The income they earn in their work state is taxed based on the tax rules of the state they reside in. As of 2024, 16 states—Arizona, Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Montana, New Jersey, North Dakota, Ohio, Pennsylvania, Virginia, West Virginia, and Wisconsin—and the District of Columbia have reciprocal tax agreements in place.
If the state of your residence has a reciprocal agreement with the state you work in, you would not have to file nonresident state tax returns for your state of employment, assuming it follows all the rules. You can simply provide your employer with the required documents.
Reciprocity can greatly simplify tax time for people who live in one state but work in another, something that's relatively common among those who live near state lines. Numerous states have reciprocal agreements with others.
The reciprocity rule deals with employees having to file two or more state tax returns: a resident return in the state where they live and nonresident returns in any other states where they might work. This ensures they can get back any taxes that were erroneously withheld. As a practical matter, federal law prohibits two states from taxing the same income.
The U.S. Supreme Court ruled against double taxation in a case called Comptroller of the Treasury of Maryland v. Wynne in 2015, stating that two or more states are no longer permitted to tax the same earnings. But filing multiple returns might be necessary to be absolutely sure that you're not being taxed twice.
For example, New York can't tax you if you live in Connecticut but work in New York, and you pay taxes on that earned income to Connecticut. Connecticut is supposed to offer you a tax credit for any taxes you paid to the other state, or you can file a New York state tax return to claim a refund of taxes withheld there.
You won't pay taxes on the same money twice, even if you don't live or work in any of the states with reciprocal agreements. You'll just have to spend a little more time preparing multiple state returns, and you'll have to wait for a refund for taxes unnecessarily withheld from your paychecks.
The table below shows 16 states where nonresident workers who live in reciprocal states don't have to pay taxes. Washington, D.C., also has a reciprocity agreement with states.

If your state doesn't have a reciprocal tax agreement with the state where you work, you will have taxes withheld in your work state. At tax time, you will have to file taxes in both states to sort out how much you owe or how much you'll be refunded from either state. When it's all settled, you still won't be taxed twice on your income.
In states that have reciprocal agreements, you can file an exemption with your employer so that you won't have taxes withheld in your work state. Make sure your employer is withholding taxes for your resident state, though.
