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 Earnings Statement to verify your tax withholdings.

Use the MyUW employee portal to update your federal and state Form W-4

Most employees can enter and update their tax withholding information using the Payroll Information module in MyUW.
