When to File a Nonresident State Tax Return

You may need to file a nonresident tax return for each state in which you worked, but did not reside. For example, if you lived in one state and worked in another, you will usually need to file a resident return for the state in which you lived and a nonresident return for the state in which you worked.

Here are other situations where you may need to file a nonresident state return:

  • You earned income in a state that is not your resident state.
  • Your employer incorrectly withheld taxes for a state that is not your resident state.
  • You had taxable gambling winnings in a state that is not your resident state.
  • You owned rental property in a state that is not your resident state.
  • You are in a partnership or are a shareholder in an S-Corporation that is based in a state that is not your resident state.
  • You received income from an estate or trust that has interest in a state that is not your resident state.

Did you know? On, you can file your resident state return, a nonresident state return, and as many additional state returns as you need for one low price! Compare this to other platforms which charge per state, not one flat rate. You may need this if you live in one state and work in another or if you moved states and earned income in each.

You generally have to file a return for the state where your employer is located, regardless of whether or not you also work there. This applies for remote employees; you will file your state return for the state you live in, or where your domicile is located, and a nonresident return for the state the employer is located in.

Note: This is not the case for remote, independent contractors. If you receive nonemployee compensation on a 1099 form, such as 1099-NEC, you only pay applicable state tax for your resident state. If you work remotely for a company in another state on contract - you do not receive a W-2 - then you do not have taxes withheld and will instead owe federal taxes, resident state taxes, and self-employment taxes.

If your income form lists any state other than your resident state, you would file a nonresident return for that state and a resident return for your state. The income gets reported on the nonresident return where the income was earned; many states - not all - have laws in place that prevent double taxation so you only pay state income tax on a portion of the income. handles this for you; we will help you prepare your federal and multiple state returns and you can be certain that you will not pay any more tax than you are legally required to.
