I am caregiving in IL but my residence is in NY state. Is my residence NY or Il?

If you maintain a NY residence, license, voting, etc, you are a NY resident. You will need to file the IL return first.

Please carefully follow these directions.

You will need to prepare IL and NY in a special order. You may need to delete both states and begin again.

1. First, prepare your non-resident IL return. This creates your tax liability for the non-resident state.
2. THEN prepare your resident  NY state return and it will generate a credit for your income already being taxed in the non-resident state.
3. The credit will be the lower of the state tax liabilities on the same income. You may owe your resident state.

It isn't possible for the program to create a credit before it knows the liability. Your returns may be wrong if you do not prepare the states in this order.
