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

The instinct that working in a no-tax state means paying no tax is the single most expensive misunderstanding in this niche. Missouri takes nothing, but Arizona still taxes residents on income earned anywhere, so the full amount lands on your Arizona return.
Missouri also has a layer below the state one, and it is the layer that survives every agreement: Kansas City and St. Louis each levy a one per cent earnings tax on wages earned inside the city, collected by the city. Nonresidents pay it on the portion of work performed there.

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