Property Tax

Missouri law sets the assessment ratio for personal property at one-third of true value throughout the state. Real properties (land and buildings) classified as commercial and industrial, are assessed at 32%; residential 19%; and agricultural 12% or true or fair market value. The local property tax rate is an aggregate of school, city, county and state levies expressed in tax per $100 assessed valuation. Commercial and industrial real property is assessed an additional county surcharge designed to replace revenues lost by the tax exemption of business inventories. 

Assessed values are established by the County Assessor’s Office.  For further question regarding assessments please contact the St Charles County Assessor’s Office.  Questions on taxes not related to the City portion or Neighborhood Improvement Districts (NID’s) contact the St. Charles County Collector’s Office.  Questions on the City portion and NID’s call the City Finance Office at (636) 327-5101.
