County Ratios

Ratio studies follow each biennial reassessment of property in Missouri.  Reassessments are completed on January 1st of each odd numbered year.  It takes approximately two years after a reassessment to complete a ratio study, so the results for the current reassessment cycle will not be immediately available.

*Historical ratios: Available upon request.
