Example: Your company is headquartered in FL, you live in IN and work in IL. You pay nothing to FL if you never set foot in it to earn wages. You must pay state income tax to IL on the wages you earned in IL, at IL tax rates. Next, you must pay income tax to IN for all taxable income, no matter where you earned it. But you get a credit on your IN (home state) return equal to what you paid on your IL wages. If you paid (witheld) too much tax to IL, the IL tax forms will tell you how to apply for the refund
