All 115 Missouri counties and county equivalents. 2 have been checked against the county's own schedule; the rest follow the state schedule below.
| Instalment | Due | Notes |
|---|---|---|
| Annual | January 1, 2027 | Taxes are payable on or before December 31, and unpaid real estate is delinquent on January 1. |
Missouri property tax is billed and collected county by county, so the collector — not the state — issues the bill. The December 31 date is uniform statewide, but charter counties and St. Louis City run their own tax-sale and payment-plan calendars, and partial opt-in counties use a separate foreclosure track.
