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.

Use Tax Notice:  The City of O’Fallon imposes a use tax on purchases from out-of-state vendors in the amount of 2.0 percent. A new Missouri law has expanded the application of the use tax so that such tax is now applicable to certain purchases from out-of-state vendors that were previously exempt. This notice is intended to apprise all interested parties of such change. Pursuant to Section 144.761 RSMo, a petition signed by fifteen percent of the registered voters of the city voting in the last gubernatorial election may be submitted to the city calling for an election to repeal the local use tax.
