Missouri reassesses property every odd-numbered year and taxes homes on just 19% of market value. A 2023 law now lets counties freeze property taxes for homeowners 62 and older, though each county must opt in.
Real property is reassessed every odd-numbered year by county assessors, and residential property is assessed at 19% of market value (agricultural at 12%). The combined rate — set by overlapping school, county, and city districts — is expressed per $100 of assessed value.
| Home Value | Estimated Annual Tax | Monthly (Escrow) |
|---|---|---|
| $221,000 (median) | $2,122 | $177/mo |
| $250,000 | $2,400 | $200/mo |
| $600,000 | $5,760 | $480/mo |
Effective rates vary within Missouri. These figures are median-tax-to-median-value estimates from U.S. Census ACS data (2019–2023 ACS 5-year (SmartAsset)) for some of the most populous counties:
| County | Effective Rate |
|---|---|
| St. Louis County | 1.14% |
| Jackson County | 1.11% |
| St. Charles County | 1.05% |
| Clay County | 1.04% |
| St. Louis city | 1.02% |
| Platte County | 0.99% |
| Boone County | 0.80% |
| Greene County | 0.67% |
Among these counties, effective rates range from about 0.67% in Greene County to 1.14% in St. Louis County. Your actual rate depends on the local mill/millage set by your county, city, and school district.
Missouri has no general homestead exemption that lowers assessed value for all owner-occupants. Relief comes through the senior freeze and the Property Tax Credit Claim (circuit breaker) programs.
Under SB 190 (2023, amended 2024), counties may adopt a senior property-tax freeze locking the tax amount for eligible owners 62+ — adoption and rules vary by county, with no income limit. Separately, the Missouri Property Tax Credit Claim ('circuit breaker') gives owners 65+ or 100% disabled a credit up to $750 (up to $1,100 for renters), subject to income limits, and 100% disabled former prisoners of war are fully exempt.
Property tax bills are due by December 31 each year. Payments made after that are delinquent and subject to penalties and interest beginning January 1.
Appeal first to the county Board of Equalization (deadlines vary, commonly the second Monday in July). Decisions may be appealed to the Missouri State Tax Commission and then to the courts.
Missouri's average effective property tax rate is about 0.79% of home value, below the national average, though rates range from roughly 0.6% to over 1.1% by county.
SB 190 lets participating counties freeze the property tax amount for eligible homeowners age 62 and older. Each county must opt in, so availability and application deadlines vary by county.
Residential property is assessed at 19% of market value. A $200,000 home has an assessed value of $38,000, to which the local rate per $100 is applied.
