Change the allowances on your Form W-4 and NC-4 when your personal or financial situation changes to update the amounts of federal and state income tax withheld from your pay.


Federal: Refer to complete Form W-4 instructions and allowance worksheets, as applicable before completing the online W-4 withholding form.

North Carolina: Refer to Form NC-4 instructions before completing the online NC-4 withholding form.

Unless you update your W-4 and NC-4 withholding information, both your federal and state income tax withholding allowances will default to single with zero allowances.
