Real Estate Tax Payments

2023 city real estate taxes are included on the St. Charles County bill.  Amounts outstanding for 2022 should be paid to the City of Lake Saint Louis. 

Use Tax Notice

The City of Lake Saint Louis 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.
