Set up an employee's tax attributes
Go to People and open the employee you want to update.
Open the "Tax Setup" tab on the employee's page.
Fill in the tax attributes your company defines for this employee, then submit them.
These company-defined tax attributes are separate from the employee's W-4 withholdings, which you set on the "Withholdings" tab.
Enter or update an employee's W-4 withholdings
Go to People and open the employee you want to update.
Open the "Withholdings" tab on the employee's page.
Enter or adjust the employee's federal and state income tax withholding elections — the details from their W-4 — then submit them.
Note: Employees can also complete their own withholdings from their personal Withholdings page, so some details may already be filled in. To see whether tax setup or withholdings are still outstanding for an employee, open their Details tab and check the Onboarding section.
