In the US we generally tax based on where you live, not where you temporarily reside.

Nope, sorry, completely wrong.

You pay taxes to the states proportionately to how much time you spent in the state for the year. Many states don't even have a "floor" for how much time an employee works in a state before they're required to pay income and payroll taxes to that state, so in some states even one day working in that state triggers tax.

Consulting firms track employees time spent in each state down to the hour so they can properly pay payroll taxes. Many consulting firms will even pay for tax return prep for employees required to work in other states long enough to trigger tax compliance.
