Oklahoma Income Tax in 2026

Oklahoma uses a low income tax with a top marginal rate of 4.75%. That rate kicks in at higher income levels; most filers fall into a lower effective bracket. Lower-income households often pay an effective state rate of 2–4%.

Combined with federal tax (10%–37%), Social Security (6.2% up to the wage base) and Medicare (1.45%), the all-in federal+state tax bite for Oklahoma residents at $100k gross typically lands in the 25%–32% effective range, depending on deductions.
