Assessor

Responsibilities


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 the taxes are based on the property value. 

The Assessor has no jurisdiction or responsibility for taxing jurisdiction budgets or establishing the tax rate.

Tax Bills


Your tax bill is comprised of three key components:
  • Assessment Authority
  • Taxing Authority
  • Collection Authority

Assessment 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.

Taxing Authority


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.

Collection Authority


The collection authority (Collector of Revenue’s Office) is responsible for collecting the amount of tax assigned to each property owner.
