Missouri income tax goes up to 4.7% at the top bracket. Calculate your combined federal + state effective tax rate for 2026. Formula shown, sources cited — no account required.
Missouri uses a graduated income tax structure with rates starting near zero and rising to a top rate of 4.7%, which applies to income above $9,072. Most working residents above entry-level wages pay the 4.7% rate on the majority of their income. For the median earner at $71,589, the effective state rate after the standard deduction and personal exemption typically runs a point or two below the top marginal rate. Missouri allows a deduction for federal income taxes paid, which is relatively rare and can meaningfully reduce state taxable income for higher earners. Social Security benefits are exempt for most retirees under the income thresholds noted above. On the federal side, Missouri's median earner typically lands in the 22% federal bracket, making the combined marginal rate roughly 26.7% — moderate by national standards. Missouri also has no estate or inheritance tax. The interaction between the federal tax deduction and state tax calculation makes Missouri's returns slightly more complex than flat-rate states but generally favorable for higher earners.

Missouri Tax Brackets Explained (2026)
Missouri has a state income tax with a top marginal rate of 4.7%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 35% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Missouri earns $71,589/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 15–17%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Missouri has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
