Statewide schedule — read this before you rely on it
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. Most counties in this state follow these dates.
Delinquent land is charged an 18% penalty on each year's delinquency plus interest, and the collector enforces the state's lien.
Collectors mail bills in the fall once the levy is set, and payment is due by December 31.

Is this county verified?
