The Saint Louis County Assessor's Office discovers, identifies, classifies and assesses all real and personal property within Saint Louis County. Functionally, the Office is comprised of:
The County Assessor is required by Missouri State Statute 137.115 to establish the fair market value of all real property as of January 1 of every odd year (like 2011 and 2013). The assessed value is applied to the tax rates established by the taxing districts to determine the amount of tax levied against a property.
The reassessment process involves establishing the value of about 389,000 parcels of real property, providing owners the opportunity to appeal, then finalizing, certifying and communicating the values to the individual taxing districts.
Throughout the process, the staff of the Assessor’s Office makes every effort to treat our customers fairly and to provide information in a clear and accessible manner.
