Live in Illinois, Work Remotely for a Wisconsin Employer: Who Taxes You?
Answer
Illinois taxes the income and Wisconsin cannot. Residency, not the location of the job, drives this answer: Illinois reaches all of a resident's income, and Wisconsin has no personal income tax to apply to the part earned inside its borders.

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 Wisconsin adds nothing on top.

Questions people actually ask
I live in Illinois and work remotely for a Wisconsin employer. Which state do I pay?
Illinois taxes the income and Wisconsin cannot. Residency, not the location of the job, drives this answer: Illinois reaches all of a resident's income, and Wisconsin has no personal income tax to apply to the part earned inside its borders.
Which state should my employer be withholding for?
Illinois. Your employer should withhold Illinois tax rather than Wisconsin tax on these wages. If a Wisconsin line is showing on your pay stub, raise it with payroll now rather than at filing time.
Does my Wisconsin employer's location alone create a Wisconsin tax obligation?
No. Wisconsin 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 Wisconsin are a different matter — those are Wisconsin-source income and can require a nonresident return.
How current is this?
