How the North Carolina estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. North Carolina uses the 2026 NC-30 percentage method: gross pay is reduced by the pay-period standard deduction and $2,500 annual value for each NC-4 allowance, then 4.09% is applied and the result is rounded to the nearest whole dollar before requested additional withholding.
Example: The official NC-30 example uses $450 of weekly wages, single filing status, and two allowances. After the $245.19 weekly standard deduction and $96.16 of allowances, $108.65 remains and rounds to $4 of North Carolina withholding. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
