In US Payroll; when it comes to tax calculation on IT0207; what drives / determine the tax calculation for the employee? Is it based on where they reside/ live(pulling from IT0006 specifically zip code) the employee's resident state or is it based on the employee's work state(state in which the employee will be working?
Please see attached what I see when I look in the schema. I always thought it IT0207 was based on where an employee resides.
Please advise,,,
