How do I tag earnings for a different jurisdiction for the US?

You can use tagged earnings when you want to tax a unit of paid time in a different jurisdiction.

For example, you want to enter 8 hours of time worked in a different location than where the person normally works. When tagged as such, the payroll process taxes the calculated pay for those units of time at the designated jurisdiction. If the employee doesn't have withholding elections for the tagged jurisdiction, the process automatically calculates the tax at the highest withholding status or allowance elections.

You do this by adding the AREA contexts (state, county, and city) as input values to the elements.
