 Message from the Collector of Revenue

Collector of Revenue, Michelle D. McBride

Thank you for visiting our website! 

Due to COVID and the Delta variant, taxpayers are strongly encouraged to pay using contactless methods: online, over the phone (1-855-227-7840), by mail or by putting payment in the drop box in the lobby of the County Administration Building at 201 N Second Street in St Charles. 

      To pay or research accounts/bills, click on a search button at the right

  To see additional information about the Office, visit

Reminder:  Online Payment Cart is disabled the first 3 to 5 business days of each month while the statutory late payment interest and penalty are updated

Payments are still accepted at the Collector's Windows in the County Administration Building during those days and the drop box inside the County Administration Building lobby also remains available for the submission of payment(s) during those days.

 Annual Billing Update

 Paying Your Bill

Paying your tax bill:

  • The Online Payment Transaction Receipt is not sufficient for license plate renewal.  The official Paid Personal Property Tax Receipt needed for license renewal will be mailed from the Collector's Office.  Please allow 5 business days for mail time and for updating of the state database.
  • Reminder: Partial Payments are accepted on existing bills.  Accounts must be paid in full to get the Personal Property Tax Receipt needed for Vehicle Registration Renewals.  All 2019 and prior Real Estate taxes must be paid in full to prevent their offering in the 2021 Tax Certificate Sale. 
  • When funds submitted exceed the amount due on an account, a credit is typically placed on the record toward future taxes.  A written request (by mail or email) from the party making the payment and containing current contact information is required for the release of funds. Duplicate Payments, are typically rejected and returned.  


Late payment interest and penalty are due on all tax payments made after January 1st of the year for which tax is assessed in accordance with State Law (Sections 52.290, 139.100, 140.100 RSMo).  The late payment interest and penalty is calculated based on the date of payment receipt or on the USPS postmark of the payment envelope.  The late payment interest and penalty increase on the first of each month.

The Personal Property bills shown on this site only display the first asset from a bill. The listing of assets on a paper bill should include everything owned on January 1st of the tax year (Section 137.115 RSMo). If a zero-dollar-due or no bill is showing, it could be because the Assessor did not receive a completed  Personal Property Assessment Form for the account.

This site will cease to accept payments at 12:01am on the 1st of each month.  It re-opens for payments around the third business day of the month.  This is to allow sufficient time for updating to the current amount due.
