Live in Illinois, Work in Alaska: Which State Taxes Your Paycheck?
Answer
One state, one return: Illinois. Alaska has no wage income tax, so working there changes nothing about what you owe. Your Illinois resident return reports the Alaska income along with everything else, and there is no credit to claim because Alaska charged you nothing.
