Use Form W-4 to change your tax withholding
If you want to change the amount of federal income tax withheld from your pay, use Form W-4 in PeopleSoft to update your payroll. The IRS recommends completing a new Form W-4 when your personal or financial situation changes, but this can be done any time. Go to the IRS website for information about Tax Withholding, including a Tax Withholding Estimator.
It’s easy to adjust the amount withheld from your King County paycheck for tax purposes using PeopleSoft to update your W-4:
- Sign in to PeopleSoft
- Select the Payroll tile
- Select W-4 Tax Information
- Enter your choices and make note of your selections
- 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.
If you have payroll-related questions, please reach out to your department’s Payroll team, call Benefits, Payroll and Retirement Operations at 206-684-1556, Option 2, or email main.payroll@kingcounty.gov.
