How do I change the withholding on my Form W-4 and NC-4?



  • Federal: Refer to the complete Form W-4 instructions before completing the online W-4 withholding form.
  • North Carolina: Refer to Form NC-4 instructions before completing the online NC-4 withholding form. If you are performing services for the University from a state other than NC, you will need to complete that state's withholding certificate and mail or fax it to the Payroll Department. Reference the delivery methods toward the bottom of this FAQ. For security purposes, do not email a form that contains your social security number.

TIP: Unless you update your W-4 and NC-4 withholding information, your federal and state income tax withholding will default to single when you are originally hired and will continue to reflect those elections. Employees hired on Jan. 1, 2020, or later, are required to complete the 2020 Form W-4 for federal payroll tax withholding purposes. 

Employees can complete their Form W-4 (Employee's Withholding Certificate) and NC-4 (Employee’s Withholding Allowance Certificate) to update their withholding anytime through as follows:

  1. Log in to using your NinerNet Username and password.
