The W-4 is designed to help employees accurately calculate their payroll tax withholding. Withholding is a very individual decision based on each person’s financial and personal situation. Each employee must make withholding decisions on their own or with the assistance of their individual tax consultant. The UW is not authorized to provide tax advice.
Submitting your tax withholding information
Effective March 10, 2020, most employees can enter and update their tax withholding information using the Payroll Information module in MyUW.
