Property records in Missouri are maintained at the county level. The County Assessor handles property valuations and assessment data. The County Collector handles tax bills and payments. These are separate offices with separate databases.
What this page covers: Missouri property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.
Where to start: For property values and tax assessments, start with the County Assessor. For tax payment history and bills, go to the County Collector. For ownership verification, you may need both the assessment records and the recorded documents.
Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Missouri. The County Assessor handles assessments; the Recorder of Deeds handles recordings. Search both if you need the full picture.
