Where does Missouri rank for take-home pay on $45,000?
Missouri ranks 17 of 51 (50 states plus DC) for take-home pay on a $45,000 salary in 2026. The median state leaves $36,956, and Oregon leaves the least at $34,974.
Missouri has nine brackets but a low 4% top rate. How does this work?
Missouri has nine brackets (more than most states), which creates complexity, but the top rate is only 4%—lower than many flat-tax states like Illinois (4.95%) or Massachusetts (5.0%). The many brackets mean you move through small increments quickly, but most earners effectively pay close to 4% on most income. A $75,000 earner pays an effective rate very close to 4% (approximately $3,000 annually), while the same earner in Illinois would pay $3,713 (4.95% flat). The real surprise is the sales tax rates, which can reach 10.85% in some areas, completely offsetting the low income tax for big spenders.
Missouri exempts all retirement income from state tax. Does this apply to everyone?
Yes. Missouri does not tax Social Security or retirement income (pensions, 401(k) withdrawals, IRA distributions) for all residents, regardless of age. Combined with the low 4% top income tax rate, Missouri is attractive for retirees, especially those who spend modestly and benefit from the low income tax rate. However, the very high sales tax rates (up to 10.85% in some areas) can offset retirement benefits for big spenders.
How Missouri ranks on $45,000

Missouri withholds $1,178 of that $45,000 in state income tax. Your next dollar earned is taxed at roughly 4.7% by Missouri on top of the 12% federal marginal rate — so a raise is taxed noticeably harder than your effective rate suggests.
