Surtax on Commercial Real Property – The surtax on commercial real property is $0.53 per $100 of assessed valuation. The tax is a replacement for the merchants and manufacturers tax, which was discontinued as a result of a reassessment in 1985. The tax is shared on a proportional basis within each county based on lost revenue from 1985. The assessed valuation on commercial real property is calculated at 32% of the market value.

Property taxes are collected by the St. Charles County Collector's Office. Get more information on the City of O'Fallon's Sewer Lateral Insurance Program.
