Missouri property tax deadlines
9 sourced dates. 115 of 115 Missouri counties have at least one.
In Missouri the county collector bills once a year, usually in November, and state law makes the tax due by December 31. Anything unpaid on January 1 is late and penalties start. A mailed payment counts on its postmark date. To appeal your value, go to the county board of equalization, usually before the second Monday in July, though some charter counties set their own date.
