Missouri Quarterly Taxes for Freelancers
Missouri recently cut its income tax to a flat rate of 2% — one of the lowest income tax rates among states that have one. Missouri has been aggressively reducing its income tax as part of a multi-year reform effort. Two Missouri cities do charge local income taxes: Kansas City charges 1% and St. Louis charges 1% on wages earned within city limits. Outside these two cities, no local income taxes apply. Missouri's standard deduction mirrors the federal amount ($16,100 for single filers), which is generous. Compared to neighboring Kansas (5.2% flat) and Illinois (4.95% flat), Missouri's 2% flat rate is dramatically lower, making it one of the more attractive states in the Midwest for take-home pay — particularly outside Kansas City and St. Louis.
