Live in Idaho, Work Remotely for a Colorado Employer: Who Taxes You?
Answer
One state, one return: Idaho. Colorado has no wage income tax, so working there changes nothing about what you owe. Your Idaho resident return reports the Colorado income along with everything else, and there is no credit to claim because Colorado charged you nothing.

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 Colorado adds nothing on top.
Colorado also has a layer below the state one, and it is the layer that survives every agreement: A few Colorado cities levy an occupational privilege tax — a flat monthly head charge on anyone working in the city, not a percentage of income. It is not an income tax and no credit offsets it.

Questions people actually ask
I live in Idaho and work remotely for a Colorado employer. Which state do I pay?
One state, one return: Idaho. Colorado has no wage income tax, so working there changes nothing about what you owe. Your Idaho resident return reports the Colorado income along with everything else, and there is no credit to claim because Colorado charged you nothing.
Which state should my employer be withholding for?
Idaho. Your employer should withhold Idaho tax rather than Colorado tax on these wages. If a Colorado line is showing on your pay stub, raise it with payroll now rather than at filing time.
Does my Colorado employer's location alone create a Colorado tax obligation?
No. Colorado 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 Colorado are a different matter — those are Colorado-source income and can require a nonresident return.
How current is this?
