Concept: Common Paymaster (USA)

Common Paymasters: Common paymasters enable you to reduce tax liability by designating a common paymaster company that serves as a single employer for:
FICA wage bases.
FUTA wage bases.
SUI wage bases for configured states.

You're responsible for ensuring eligibility under applicable law for:
All companies included in the common paymaster relationship.
All employees paid by the common paymaster.
All states configured in the common paymaster relationship for SUI aggregation.
Retro Pay Calculations: You can:
Calculate differences for workers who transfer companies that are in a common paymaster relationship. When the tax authorities between the companies are different, Workday considers the tax elections in the common paymaster company.
Pay those differences using on-demand additional payments in the company that the differences are from. Use tax authority worktags.

Retro pay calculations don't support:
When the source or target companies are outside the common paymaster relationship, and the tax authorities are different.
The Other Authority
worktag because Workday doesn't consider local other tax authorities from the managing company.
In-Progress Pay Results for Multiple Jobs: Multiple in-progress pay results for a worker in a common paymaster relationship are aware of limits and balances of the other results when you meet these conditions:
When the jobs are in 1 pay group, run the pay calculation for that pay group.
When the jobs are in multiple pay groups:
The pay groups must share the same period schedule.
You must calculate the pay groups together in the same pay calculation run.

If you make an adjustment to any of these in-progress results, recalculate them all together again in the same pay calculation run. That way, the in-progress results can continue to account for limits and balances. If you recalculate any of these results independently from the others:
The in-progress results won't be able to account for limits and balances of the other results until you complete the pay result.
You could have over or under withholding.
Multiple Jobs and Different Period Schedules: Workday determines the limits and balances to apply to in-progress results by looking at the last completed pay result for workers with multiple jobs that you are:
Paying on different period schedules.
Calculating in different pay calculation runs.

After you complete any pay result for a worker or pay group, you must recalculate any remaining in-progress results. Otherwise, you might have over or under withholding.
