Use new W-4 to change your tax withholding 

Form W-4 is used to let your employer know how much federal income tax to withhold from your pay. The IRS recommends completing a new Form W-4 when your personal or financial situation changes. This year, the IRS redesigned Form W-4 to reduce complexity and improve accuracy. Go to the IRS website for information about Tax WithholdingFAQs on the 2020 Form W-4, and a Tax Withholding Estimator.

If you would like to adjust the amount withheld from your King County paycheck for tax purposes, please use PeopleSoft to update your W-4:

  • Sign in to PeopleSoft. Must be logged into VPN to access this PeopleSoft feature.
  • Select the Payroll tile
  • Select W-4 Tax Information

  • Review and Submit

For additional instructions, check out the W-4 Withholding Certificate video or the Updating Your W-4 training document, both available in the PeopleSoft Knowledge Center.
