How North Carolina withholding works
The 2026 NC-30 instructions set out a simple formula:
- Subtract the standard deduction for the pay period – $12,750 a year for single, married or surviving spouse; $19,125 for head of household.
- Subtract $2,500 a year for each NC-4 allowance.
- Multiply by 4.09% and round to the nearest whole dollar.
The NCDOR’s example: a single employee paid $450 a week with two allowances – (450 − 245.19 − 96.16) × 4.09% = $4.44, withheld as $4. This calculator reproduces it.
The 0.1-point cushion means North Carolina deliberately withholds a little more than the tax rate.
Worked example: $60,000 in North Carolina
Single, $60,000 salary, paid every two weeks, North Carolina
Gross pay is $2,307.69 per paycheck. Federal income tax is $193 and Social Security and Medicare $177. North Carolina withholds $74. Take-home pay is $1,864 per paycheck, or $48,466 a year.
