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

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 California still taxes residents on income earned anywhere, so the full amount lands on your California return.

Questions people actually ask
I live in California and work remotely for a Illinois employer. Which state do I pay?
California taxes the income and Illinois cannot. Residency, not the location of the job, drives this answer: California 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?
California. Your employer should withhold California 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.
