Tax Withholding Questions

The information included with your W-4 forms will impact your tax withholdings. 

Your original W-4 forms/instructions are included with the onboarding checklist issued by HR at the time of hire.  However, if you wish to later change your W-4s, please complete the Form W-4  and SC W-4 manually and bring them to the Payroll Office for processing. The change will go into effect on your next paycheck, unless the payroll for the upcoming paycheck has already been processed.  Further information on Employee Self Service Form W-4 will be released with future enhancements of PeopleSoft HCM.
