Live in Kentucky, Work Remotely for a Idaho Employer: Who Taxes You?
Answer
Kentucky taxes the income and Idaho cannot. Residency, not the location of the job, drives this answer: Kentucky reaches all of a resident's income, and Idaho 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. Idaho takes nothing, but Kentucky still taxes residents on income earned anywhere, so the full amount lands on your Kentucky return.

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