University employees may elect to have additional federal and/or state tax withheld from their earnings by completing the Additional Tax Withholding Form , and submitting it to Employee Services
This tax withholding is supplemental to the federal and state amounts claimed on the W-4. Additional tax withholding does not replace and cannot be used in lieu of what the employee has claimed on his/her W-4.
Additional amounts must be in whole dollars. These additional amounts will continue to be withheld until the employee fills out a new Additional Tax Withholding Form to change or cancel the amounts previously requested.
For more information on withholding, see IRS Publication 15 .
