Social Security benefits are not taxed in Missouri for lower- and middle-income retirees — the exemption phases out above $85,000 in adjusted gross income for single filers and $100,000 for married couples. For most retirees below those thresholds, Missouri effectively exempts their Social Security entirely. The cost-of-living index of 88.9 strengthens the case for retiring here — everyday expenses run 11% below the national average, meaning a given nest egg lasts longer than it would in a higher-cost state. Both Kansas City and St. Louis have strong healthcare networks and offer genuine cultural amenity for active retirees. Smaller communities like Springfield, Columbia, and Joplin provide even lower living costs with good regional services. Missouri levies no estate or inheritance tax, which simplifies multi-generational planning. Use the retirement calculator to model how Missouri's Social Security exemption and below-average costs interact with your withdrawal plan.
