St. Charles County property tax bills will go out in the mail and become available online in late November. Here’s a quick look at important information and dates:
- Tax bills won’t be finalized until Nov. 15, so the County Collector’s Office won’t be able accurately quote your bill amount until then.
- The online version of your tax bill will be available to view and pay starting the last week of November. Hard copy bills will all be mailed before Dec. 1. If you do not receive your tax bill by Dec. 10, find it online or call the Collector’s Office at 636-949-7470. Your tax bill is still due, even if you don’t receive a paper copy.
- Have you moved in the last year? If so, check now to make sure the address for your personal property is updated so your bill goes to the right home. Call the County Assessor’s Office, 636-949-7425, to check your registered address, then complete the Personal Property Change of Address Form to update it if needed.
- All property tax payments are delinquent on Jan. 1. Payments that are made or postmarked Jan. 1 or later will be subject to late fees and interest. It’s always better to pay your bill early, just in case something goes wrong with your payment method.
- Property tax bills can be paid online, by mail, over the phone (1-855-227-7840), in person, or placed in the County’s drop box.
- If you have taxes that are automatically paid by escrow, such as the tax on your house, you will still receive a copy of your bill. You do not have to pay this bill if it is being paid by escrow. The copy is purely for your information.
