Re-Assessment 2023

Missouri Revised Statute - Chapter 137 requires that all counties re-assess real estate property on the first day of the year in the odd years. January 1st, 2023 is the current date of assessment. All real property values are set on this date.

Re-assessment is the process that helps to validate that real property is valued at its current market value. All real property in Clay County is valued with uniform and consistent procedures following Missouri Revised Statutes - Chapter 137. Over time the value of property changes due to market conditions, location, condition of the property, and other physical and economic factors. Some property values change more rapidly than others. Reassessment identifies changes in market value, along with property condition to determine current market value.

The Assessor's Office, on the date of assessment, is assigned the task of assessing or valuing the real property at Market Value (PDF).

When determining a property classification (Agricultural, Residential, or Commercial) the Clay County Assessor's Office follows Missouri Revised Statute - Chapter 137, specifically 137.016, 137.017, and 137.021.

Approximately April 1st, Change of Valuation Notices are mailed to property owners whose property has increased in value and all commercial property. Change of Valuation Notices for all properties is available online.

Mass Appraisal Definition - IAAO Standard on Mass Appraisal of Real Property

Market value for assessment purposes is generally determined through the application of mass appraisal techniques. Mass appraisal is the process of valuing a group of properties as of a given date using common data, standardized methods, and statistical testing. To determine a parcel's value, assessing officers must rely upon valuation equations, tables, and schedules developed through mathematical analysis of market data.

Unless required by law, values for individual parcels should not be based solely on the sale price of a property; rather, valuation schedules and models should be consistently applied to property data that is correct, complete, and up-to-date.
