North Carolina withholds a flat 4.09% after a $12,750 standard deduction and $2,500 per NC-4 allowance.
How North Carolina withholding works
Your employer annualizes your wages, subtracts the North Carolina standard deduction ($12,750 for single, married and surviving-spouse filers; $19,125 for head of household) and $2,500 per NC-4 allowance, multiplies by 4.09% and divides by your pay periods, rounding to the nearest dollar.
Why 4.09% and not 3.99%?
North Carolina's 2026 income tax rate is 3.99%, but the withholding tables add 0.1% so that most people don't end up owing at tax time. Any over-withholding comes back as a refund.
NC-4 allowances
You get extra allowances on Form NC-4 for itemized deductions above the standard deduction, certain adjustments and tax credits (one allowance per $2,500 of deductions or $103 of credits). Most single people with one job claim 0.
No local income tax
North Carolina cities and counties don't tax wages, and there's no state disability deduction — your check has federal tax, FICA and the 4.09% state withholding.
