North Carolina imposes a flat individual income tax. The rate is 4.25% in 2025 and is scheduled to drop to 3.99% in 2026 under S.L. 2023-134, with further reductions contingent on revenue triggers. Section 125 cafeteria-plan salary reductions and Section 132(f) qualified transportation fringes reduce NC taxable wages, so the employee savings stack is federal marginal rate plus 7.65% FICA plus the flat NC rate. A $3,300 healthcare FSA election saves about $1,190 for a 22% federal bracket NC employee in 2025 versus about $1,050 in no-tax Florida. Matchbook updates the NC marginal-rate constant annually as the flat rate steps down.
