Tax Payment Information

Ways to Pay
Tax payments are due upon receipt of the annual bill. Tax payments are subject to late payment interest and penalty if not paid by Dec. 31 of the tax year. Technical difficulties with making phone or online payments do not extend the statutory deadline to pay without late payment penalties and interest. Receipts for payments made by mail, online, phone, or placed in the drop box located inside or outside the Administration Building are mailed approximately five business days after payment is received and processed by the Collector of Revenue’s office. Receipts for payments made in-person at the Collector’s service windows are provided same-day.

Following are ways to pay:

• By mail using check, money order or cashier’s check. Make payable to Michelle D. McBride or St. Charles County Collector of Revenue. Mail to Michelle D. McBride, St. Charles County Collector of Revenue, 201 N. Second St., Room 134, St. Charles, MO 63301. Include remittance stub, if available, and write account number on the payment. Do not mail cash. 

Mailed payments are accepted as of the United States Postal Service (USPS) postmark. If there is no USPS postmark, payment will be accepted on the date the Collector of Revenue’s office receives the envelope. If payment is placed in the mail on Dec. 31, it might not be postmarked until the next business day and could result in the addition of statutory late payment interest and penalty.

• Online using e-check ($2.00 fee) or debit/credit card (fee of about 2.5 percent of the total amount due). Taxpayers can pay online at StCharlesMoCollector.com. Payments made on this site are posted based on the online payment transaction date/time. Early payment is highly recommended when paying online in case of technical difficulties.

Many taxpayers opt to use online payment systems through banks to pay taxes. The Collector of Revenue urges those who use these systems to initiate payment at least five working days prior to Dec. 31. The payment date for these transactions is registered as the date payment is received by the Collector of Revenue’s office, not the date a taxpayer initiates the transaction through their bank.

• By phone using e-check ($2.00 fee) or debit/credit card (fee of about 2.5 percent of the total amount due). Call the toll-free tax payment line at 1-855-227-7840 and follow the prompts. Taxpayers need the tax year and bill number located on the statement to use this system. 
• By submitting check, money order or cashier’s check in the drop box inside or outside the County Administration Building at 201 N. Second Street in St. Charles. Include remittance stub, if available, and account number on payment in an envelope. Do not place cash in the drop box. PLEASE NOTE: The County drive-up drop box is now located on Monroe Street near the corner of N. Second. Also, a payment placed in the outside City of St. Charles drop box on Second Street could result in late payment penalties if it is not received by the Collector of Revenue by the due date. 
• In person: Taxpayers who have questions about their bill or need a receipt immediately may pay in person at the Collector of Revenue’s service windows at the County Administration Building, 201 N. Second Street in St. Charles, 8 a.m.–5 p.m., Monday–Friday, excluding Friday, Dec. 23 and Monday, Dec. 26, when County offices are closed in observance of Christmas Eve and Christmas Day. Payment also may be submitted in the indoor drop box in the first floor lobby of the County Administration Building. Those visiting the service windows will need to register for the Collector’s queue through the QLess kiosk in the lobby, through the QLess app on their mobile device, or through the QLess link available at sccmo.org/Collector or sccmo.org/QLess. Monitors in the lobby and a text notification on a mobile device will update those in the queue, and taxpayers will be alerted visually and audibly through the monitor or their mobile device when it is their turn to approach the windows. County staff in the lobby will be available to assist taxpayers with QLess. 
   
   At the Collector’s service windows, payment is accepted by cash, debit/credit card (fee of about 2.5 percent of the total amount due), check, money order, or cashier’s check. For those submitting payment through the lobby drop box, check, money order or cashier’s check is accepted; include remittance stub, if available, and account number on payment in an envelope.
