The St. Charles County Assessor is mailing 2025 Notices of Real Estate Assessment to property owners starting the week of April 28. State law requires the Assessor to revalue all real estate property in the county as of Jan. 1 of odd-numbered years.
The total collective value of all residential property in St. Charles County has increased 8.4% since the last assessment in January 2023. Individual property values may have changed more or less than that, based on their location and features.
The notices will be sent in three mailings: Washington, Wentzville, and Fort Zumwalt school districts first; Francis Howell, St. Charles and Orchard Farm school districts second; and finally, to people approved in 2024 for the Senior Tax Relief program. (Approved 2024 Senior Tax Relief applicants will get an insert explaining the effects of the tax relief program, which affects the amount of tax they owe, but does not freeze their assessed value.)
The notices include a QR code that property owners can scan with their smartphone to view more details about their property through the Assessor’s property database. Also, the interactive Assessor website at sccmo.org/Assessor provides a summary analysis of assessment and local data including a comparable sales search and interactive map.
Taxpayers have 10 days from the mailed date on the notice to schedule an informal hearing with a staff member from the Assessor’s office to discuss the property value or classification. They can schedule by calling 636-949-7431, 8 a.m.–5 p.m., Monday–Friday. These scheduled informal hearings will be conducted from the last week of April through early June. If an agreement is not reached after the informal hearing, the property owner could then file an appeal with the Board of Equalization. Information on the appeal process and answers to frequently asked questions are available at sccmo.org/Assessor, or taxpayers can contact the Assessor’s office.
