State Income Tax Project

Project Overview

Prior to the implementation of Workday, it wasn’t feasible to withhold state taxes for employees living outside Washington. The State Income Tax Project delivers a software solution supporting the automatic reporting of state income taxes for WSU paychecks, a welcome change for many employees at WSU who live outside Washington. Starting in January 2022, state taxes will be automatically withheld from employee paychecks.

WSU has contracted with Automatic Data Processing, Inc. (ADP), a company specializing in providing tax software solutions, to provide payroll tax reporting functionality. WSU will integrate Automatic Data Processing, Inc. (ADP) with Workday to support the automatic withholding of state taxes for employees who live in states with an income tax requirement.
