We wish to thank all of the Clay County taxpayers for their feedback and their patience. As always, if you do not prefer to file your assessment online please call our office at 816-407-3500 option 3; and we will notate this on your account so you can receive the paper Assessment form.

The Assessor's Office is tasked to ensure that the tax burden is distributed equitably among all property owners. To accomplish this all property is valued with uniform and consistent processes and procedures following Missouri Revised Statutes.

The Personal Property section provides you with a connection to many of the personal and business property assessment lists and forms used by the Assessor's Office, along with a comprehensive list of FAQs for business and personal property.

The Real Estate section provides a connection to resources including a Parcel Search that provides valuation and appraisal information, and Change of Valuation Notices.

The GIS/Mapping division creates, manages, and publishes land parcel data using current geographical information system (GIS) technology. Custom maps are available for purchase.
