Reciprocal tax agreements allow residents of one state to work in other states without having taxes for that state withheld from their pay. They would not have to file nonresident state tax returns there, assuming they follow all the rules. You can simply provide your employer with a required document If you work in a state that has reciprocity with your home state.
This 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 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.
As an 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.
States With Reciprocal Agreements
The map below shows 17 orange states (including the District of Columbia) where nonresident workers who live in reciprocal states don't have to pay taxes. Hover over each orange state to see their reciprocity agreements with other states, and to find out which form nonresident workers must submit to their employers for exemption from withholding in that state.
Arizona has reciprocity with one neighboring state—California—as well as with Indiana, Oregon, and Virginia. File Form WEC, the Withholding Exemption Certificate, with your employer for an exemption from withholding.
District of Columbia
You don't have to file a tax return in D.C. if you work in there and you're a resident of any other state at all. Submit exemption Form D-4A, the "Certificate of Nonresidence in the District of Columbia," to your employer. Unfortunately, this only works in reverse with two states: Maryland and Virginia. 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.

- All these forms are available on their states' websites, and Illinois even offers one that's interactive—you can complete it online, then simply download it or print it out. Your human resources department mostly likely has the appropriate form on hand as well, particularly if you work for a large business that's situated near a state line.
- Taxes for your work state will be withheld from your pay if you fail to submit the form, but you won't lose the money, thanks to the U.S. Supreme Court. Your home state should provide that tax credit equal to the amount of tax you paid to your work state, even if it doesn't have reciprocity with that state.
- Your other option is to simply file a non-resident return in the state where you work to claim a refund for the taxes that were withheld there.
