Missouri Tax Calculator
Missouri has a progressive income tax with a top rate of 4.8% — with a combined sales tax of ~8.25%.
Missouri's nine-bracket income tax ranges from 2% to 4.8%, with a legislative plan to gradually reduce it to a flat 4.7% in coming years and further cuts scheduled. The state sales tax is 4.225% plus up to 5.5% local additions, producing combined rates around 8.25% in some areas and exceeding 10% in Kansas City and other cities. MO fully conforms to the federal standard deduction. Property taxes are close to the national mean at ~0.97%, with significant variation between St. Louis suburbs and rural counties. Missouri exempts Social Security and most pension income, and offers a public pension exemption. The state's tax profile straddles midwestern moderate — Kansas City offers a notable tax-friendlier alternative to nearby Illinois, while St. Louis's earnings tax adds a 1% local wage tax on top of state rates. Missouri's revenue base is supplemented by tourism (Branson), agriculture, and a growing logistics sector.
