Live in Wyoming, Work in Illinois: Which State Taxes Your Paycheck?
Answer
Only Illinois taxes you. Illinois withholds from wages earned inside the state and you file a Illinois nonresident return. Wyoming levies no personal income tax on wages, so there is no resident return on the other side — and no credit, because there is no Wyoming tax to offset.

Living in a state with no income tax removes the resident return, but it does not shelter income you earn somewhere else. Illinois taxes what is earned inside Illinois, whoever earns it, and a nonresident return is how that gets settled.
