How to Use North Carolina Income Tax Calculator Online
North Carolina individual income tax is administered by the North Carolina Department of Revenue (NCDOR) and features a streamlined single-rate flat tax structure. Over the past decade, the North Carolina General Assembly has enacted aggressive fiscal reforms, eliminating graduated tax tiers and steadily lowering the flat income tax rate from 5.75% to 4.75% (2023), 4.50% (2024), 4.25% (2025), and 3.99% (2026).
