If you’re a New Jersey resident and work in New York State, you’ll need to file a New Jersey resident return and a New York State nonresident return.
New Jersey requires you to pay tax on all of your income, regardless of where it is earned. In addition, New York collects taxes on the income you earned while working in the state. This income won’t be double-taxed because New Jersey gives you a tax credit for taxes paid to other jurisdictions.
This credit reduces your New Jersey Income Tax liability so that you don't pay taxes twice on the same income. However, this isn’t a dollar-for-dollar refund of the taxes you paid to New York. Per the State of New Jersey, your credit can't be more than the amount you would’ve paid if you earned the income in New Jersey (rather than New York).
To ensure accurate calculations of the credit on your New Jersey return, always complete the non-resident New York return first.

- Open or continue your return.
