Live in Alaska, Work in Illinois: Which State Taxes Your Paycheck?

Work state onlyIllinois withholds

Answer

Illinois withholds, Alaska does not. As a Alaska resident you have no home-state income tax return at all, so the Illinois nonresident return is the whole of your state filing. Nothing offsets the Illinois tax, because a credit has to be claimed against a home-state tax that does not exist.

This is the mirror image of the more common commute. There is no home-state return to file, so the Illinois nonresident return carries the whole obligation — and because Alaska charges nothing, there is no credit mechanism involved anywhere.

    File a Illinois nonresident return for the wages you earned in Illinois. Alaska has no wage income tax, so there is no second return and no credit to claim.
