How it works
- Step 1 — Enter gross income, pick a filing status, and confirm the deduction (editable).
- Step 2 — The 2026 flat rate of 3.99% is fixed — North Carolina has no tax brackets.
- Step 3 — Calculate: taxable income = gross − deduction; tax = taxable income × 3.99%.
Worked example, hand-checked: a single filer earning $75,000 with the $12,750 standard deduction has $62,250 of NC taxable income. $62,250 × 0.0399 = $2,483.775, rounded to $2,483.78 per year (about $206.98 per month). Rate source: Tax Foundation, “2026 North Carolina Tax Rates & Rankings” (flat 3.99% individual rate), consistent with NCDOR withholding guidance cited by Deel — the 4.25% (2025) → 3.99% (2026) cut enacted by Session Law 2023-134.
Disclaimer: this is an estimate for planning only, not tax advice. Real NC tax starts from federal AGI with state adjustments, credits, and local rules that this simple calculator does not model. Confirm figures with NCDOR or a tax professional before filing.
