Update your payroll tax withholdings online
The university is not authorized to provide tax advice. Each employee must make withholding decisions on their own or with the assistance of their individual tax consultant. After you submit a tax withholding update, we encourage you to monitor your Payslip to verify your tax withholdings.
Most employees can use Workday to update your federal and state withholding elections.
