What this income means in Missouri
Lower earners get the most from Missouri's federal tax deduction, which is largest as a share of federal tax at modest incomes. A single filer earning $30,000 pays $456 to Missouri, a 1.52% effective rate, and takes home $25,829. At $50,000 the state bill is $1,368 and take-home is $40,987. Living or working in Kansas City or St. Louis adds the 1% earnings tax, which applies from the first dollar of pay with no deduction or 0% band, so it weighs more on a small paycheck than the state's rate suggests.
