Missouri income tax overview
Missouri has a progressive income tax with a top rate of 4.8%, continuing a multi-year phase-down from 5.4%. Missouri's tax reform has been making the state increasingly competitive in the Midwest. The standard deduction follows federal amounts. Missouri has a unique provision allowing residents to deduct a portion of their federal income tax paid, similar to Alabama and Oregon, which reduces the effective Missouri tax rate for most workers. Kansas City and St. Louis both levy local earnings taxes of 1% on residents and workers, adding to the total tax burden for those metro area workers.
