Flooding Update: Application for Removal of Residential Improvements
Homeowners whose property is destroyed by flooding can apply to have their real estate assessment modified through the St. Charles County Assessor’s office. The property must be inspected and determined to be “unsafe” and uninhabitable by the St. Charles County Division of Building and Code Enforcement.

Real estate assessments went out in April. Please watch the video below to learn about the process.
The Assessor is charged with placing a fair market value on property as of the tax date. The property tax in Missouri is “ad valorem,” meaning taxes are based on property value.
The Assessor has no jurisdiction or responsibility for taxing jurisdiction budgets or establishing the tax rate.

Certificate of Non-Assessment (Tax Waiver)
A Certificate of Non-Assessment, also known as a tax waiver, may be obtained at the Assessor's Office if you did not own a vehicle in St. Charles County on January 1. The Certificate is required by the Missouri Department of Revenue to license motor vehicles or obtain a business license in St. Charles County. Learn more about requirements for the Certificate of Non-Assessment.

Your tax bill is comprised of three key components:
- Assessment Authority
- Taxing Authority
- Collection Authority
The assessment authority (Assessor’s Office) is responsible for establishing the fair market value of all property within St. Charles County as of the tax date. This assures the tax burden is distributed fairly among those responsible for payment.
The taxing authority (school, city, fire districts, etc.) establishes the tax rate based on the budgetary requirements needed to appropriately fund the services provided within their jurisdiction.
The collection authority (Collector of Revenue’s Office) is responsible for collecting the amount of tax assigned to each property owner.
