Arkansas has a graduated individual income tax with a top marginal rate of 3.9% for tax years 2025 and 2026, down from 4.9% in 2023. The stack for a pre-tax dollar is federal marginal plus 7.65% FICA plus 3.9% state at the top bracket, so a $3,300 healthcare FSA election saves about $1,180 for a 22% federal bracket Arkansas employee. Matchbook recomputes the marginal stack at 3.9% (not a flat 4.9% or 5.0% that older state tables still show) and widens DCFSA and FSA under-election guardrails for mid-income Arkansas households where the state layer is material.
