Missouri State Income Tax — 2026 Overview
Missouri uses a progressive state income tax system with rates ranging from 1.5% to 4.8%. The more you earn, the higher the marginal rate on income above each bracket threshold. Your filing status (single vs. married) also determines which bracket table applies.
Federal Taxes in Missouri
Regardless of which state you live in, all employees pay the same federal income tax rates. For 2026, the federal brackets range from 10% on the first $11,600 of taxable income up to 37% on income above $609,350 (single filers). Your taxable income is reduced by the standard deduction ($14,600 for single, $29,200 for married filing jointly) and pre-tax contributions like 401(k) and health insurance.
FICA Taxes — Social Security & Medicare
Every worker in Missouri pays 6.2% in Social Security tax on wages up to $168,600, and 1.45% in Medicare tax on all wages. High earners pay an additional 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married filing jointly). FICA taxes are the same in every state.
How to Increase Your Take-Home Pay in Missouri
The most effective ways to reduce your tax withholding and increase net pay are: maximizing traditional 401(k) contributions (reduces federal and most state taxable income), contributing to an HSA if you have a high-deductible health plan, and ensuring your W-4 accurately reflects your filing status and any additional allowances. Pre-tax benefits like commuter benefits or FSA contributions also lower your taxable wages.
