The North Carolina bonus tax calculator at the top of this page helps employers quickly estimate employee take-home pay (also known as net pay) for bonuses. When applicable, it uses the state’s flat 4.35% withholding rate for supplemental wages.

Does North Carolina tax bonuses?

Yes. North Carolina taxes bonuses and other supplemental wages using the state’s flat 4.35% income tax rate. If the bonus (or other supplemental wage) is paid separately or in a single combined payment with regular wages but itemized, the employer can choose one of the following methods — if income tax has already been withheld from the employee’s regular wages:

  1. Withhold a flat 4.35% from the bonus amount, or
  2. Combine the bonus with the most recent regular wages, calculate withholding on the total as a single payment, then subtract the amount already withheld from regular wages.

 

If no tax was withheld from regular wages, employers must use method 2 above.

 

Vacation pay is treated as regular wages if it replaces a typical pay period. However, if vacation pay is paid in addition to regular wages, it is considered supplemental and should be taxed accordingly.
