North Carolina applies a single flat state income tax rate, which makes take-home pay easier to estimate than in bracketed states. This calculator subtracts federal income tax, Social Security, Medicare, and North Carolina’s 4.5% flat tax from your gross pay to show your net paycheck.
How it works
Your paycheck is reduced by four main taxes. First, gross pay is annualized based on your pay frequency. Then:
federal tax = brackets applied to (annual gross − federal standard deduction)
social sec = 6.2% of wages up to the wage base ($168,600)
medicare = 1.45% of all wages (+0.9% over $200,000)
NC state tax = 4.5% of (annual gross − NC standard deduction)
The federal standard deduction is $14,600 (single) or $29,200 (married jointly) for 2024. North Carolina’s standard deduction is $12,750 (single) or $25,500 (married jointly), and the remainder is taxed at the flat 4.5% rate. Net annual pay is gross minus all four taxes, divided back into your pay periods.
Example
A single worker earning $60,000 a year has roughly $5,200 in federal income tax, $3,720 Social Security, $870 Medicare, and 4.5% of ($60,000 − $12,750) = about $2,126 in North Carolina tax. Take-home is around $48,000, or about $1,850 per biweekly check.
Notes
This is a simplified estimate. It does not model 401(k), HSA, or health-premium deductions, W-4 adjustments, or the additional Medicare tax interaction with filing status. North Carolina’s flat rate is scheduled to decline in future years, so confirm the current rate and standard deduction with the North Carolina Department of Revenue at ncdor.gov.
