Can employees enter their W-4 information in Namely Payroll?

No. The admin(s) must enter tax information for each employee directly in Namely Payroll under Employee > Tax. Admins can give employees the power to request changes on their W-4 by Creating a Workflow in HRIS. Once the workflow has been created, employees can go to their profile then select the three dots in the upper right-hand corner and Request a Change using the W-4 workflow.
