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

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