Withholding/Address Changes

Address changes provide the payroll office with your correct address to which your W-2 is mailed. It is important to keep this updated so that you receive your tax documents in a timely manner. The payroll office can update your changes via email using the form provided here.

Your W-4 status determines how much Federal and State tax is withheld from your check. If you need information on what you should claim, browse our W-4 Instructions. To change your withholding status you may update your changes using the form provided here. If you are not a U.S. Citizen, you may not use this form. Any changes to your payroll withholding status need to be completed in the Payroll Services Office, building 1, room 107.
