Live in Utah, Work Remotely for a Illinois Employer: Who Taxes You?
Answer
Utah gets all of it. Because Illinois does not tax wage income, no Illinois withholding exists and no Illinois return is required — but Utah taxes residents on worldwide income, so every dollar earned in Illinois still belongs on your Utah resident return.

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

Questions people actually ask
I live in Utah and work remotely for a Illinois employer. Which state do I pay?
Utah gets all of it. Because Illinois does not tax wage income, no Illinois withholding exists and no Illinois return is required — but Utah taxes residents on worldwide income, so every dollar earned in Illinois still belongs on your Utah resident return.
Which state should my employer be withholding for?
Utah. Your employer should withhold Utah 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.
