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

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