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 a 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 History of Double Taxation

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 so 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.

States With Reciprocal Agreements

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.

You don’t have to file a nonresident return in either of these states if you live in D.C. but work in either of these states.
