Live in Illinois, Work Remotely for a Alabama Employer: Who Taxes You?
Answer
One state, one return: Illinois. Alabama has no wage income tax, so working there changes nothing about what you owe. Your Illinois resident return reports the Alabama income along with everything else, and there is no credit to claim because Alabama charged you nothing.

Crossing into a state with no income tax does not lower your tax bill, because your home state is not taxing you on where you work — it is taxing you on where you live. Illinois reaches all of a resident's income, and Alabama adds nothing on top.
Alabama also has a layer below the state one, and it is the layer that survives every agreement: Several Alabama municipalities levy an occupational licence fee on wages earned inside the city — Birmingham is the largest. It is collected by the city, not the Department of Revenue, and no state agreement or credit covers it.

Questions people actually ask
I live in Illinois and work remotely for a Alabama employer. Which state do I pay?
One state, one return: Illinois. Alabama has no wage income tax, so working there changes nothing about what you owe. Your Illinois resident return reports the Alabama income along with everything else, and there is no credit to claim because Alabama charged you nothing.
Which state should my employer be withholding for?
Illinois. Your employer should withhold Illinois tax rather than Alabama tax on these wages. If a Alabama line is showing on your pay stub, raise it with payroll now rather than at filing time.
Does my Alabama employer's location alone create a Alabama tax obligation?
No. Alabama sources wages to the place where the work is physically performed, and it does not apply a convenience-of-the-employer rule that would override that. Days you actually spend working inside Alabama are a different matter — those are Alabama-source income and can require a nonresident return.
How current is this?
