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

The instinct that working in a no-tax state means paying no tax is the single most expensive misunderstanding in this niche. Washington takes nothing, but Iowa still taxes residents on income earned anywhere, so the full amount lands on your Iowa return.
