Live in Idaho, Work Remotely for a Illinois Employer: Who Taxes You?
Answer
Idaho taxes the income and Illinois cannot. Residency, not the location of the job, drives this answer: Idaho reaches all of a resident's income, and Illinois 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. Idaho reaches all of a resident's income, and Illinois adds nothing on top.

Questions people actually ask
I live in Idaho and work remotely for a Illinois employer. Which state do I pay?
Idaho taxes the income and Illinois cannot. Residency, not the location of the job, drives this answer: Idaho reaches all of a resident's income, and Illinois has no personal income tax to apply to the part earned inside its borders.
Which state should my employer be withholding for?
Idaho. Your employer should withhold Idaho tax rather than Illinois tax on these wages. If a Illinois line is showing on your pay stub, raise it with payroll now rather than at filing time.
Does my Illinois employer's location alone create a Illinois tax obligation?
No. Illinois 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 Illinois are a different matter — those are Illinois-source income and can require a nonresident return.
How current is this?
The Idaho and Illinois rules on this page were last checked against Idaho State Tax Commission and Illinois Department of Revenue on 2026-08-07.
