Withholding Formula (Effective Pay Period 06, 2017)

  1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
  2. Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program and Flexible Spending Account - health care and dependent care deductions) from the amount computed in step 1.
  3. Add the taxable biweekly fringe benefits (i.e., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
  4. Multiply the adjusted gross biweekly wages by 26 to obtain the gross annual wages.
  5. Determine the standard deduction allowance by applying the following guideline and subtract this amount from the annual wages:

    If the Employee Is:

    The Standard Deduction Is:

    Nonresident Alien, Regardless of Marital Status




    Married or Qualifying Widow(er)


    Head of Household


  6. Determine the exemption allowance by subtracting the amount from the gross annual wages to compute the taxable income:

    Exemption Allowance = $2,500

  7. Multiply the annualized taxable wages calculated in step 6 by 5.599 percent to determine the annual tax amount.
  8. Divide the annual North Carolina tax withholding calculated in step 7 by 26 and round to the nearest dollar to obtain the biweekly North Carolina tax withholding.
  9. If the employee is a nonresident alien (NRA), and is claiming additional withholding, subtract the applicable amount shown in the table below from the additional withholding (but not less than zero).
