Overview
North Carolina uses a flat tax rate system, making withholding straightforward. The rate has been steadily declining in recent years as part of the state’s ongoing tax reform. The state uses standard deductions and allowances to determine taxable income.
State Income Tax (SIT)
North Carolina imposes a flat state income tax rate of 4.09% for 2026. Withholding is calculated by annualizing wages, subtracting the standard deduction and allowances, then applying the flat rate. Standard deductions are $12,750 for Single/Married/Surviving Spouse and $19,125 for Head of Household. Each allowance is worth $2,500. Tax amounts are rounded to the nearest dollar.
| Tax Structure | Flat rate: 4.09% for 2026 |
| State Withholding Form | Form NC-4 |
| Filing Statuses | S, M, H |
| Allowance Value | $2,500 per allowance |
| Standard Deduction (Single/Married) | $12,750 |
| Standard Deduction (Head of Household) | $19,125 |
| Rounding | Nearest whole dollar |
Supplemental Wages
North Carolina supports the following supplemental calculation methods. When using the flat method, the supplemental rate is 4.09%.
Employer State Unemployment Tax (SUTA)
Your assigned SUTA rate will be based on your company’s experience with unemployment claims. New employers typically start at the default rate of 1.0%.
| Tax Type | Employer-paid only |
| Default New Employer Rate | 1.0% |
| Rate Assignment | Experience-rated; assigned annually by the state |
Other Taxes & Obligations
North Carolina does not currently impose significant additional state-level payroll taxes beyond SIT and SUTA. This keeps payroll relatively streamlined compared to states with multiple layers of tax obligations.
