ST. CHARLES, Mo. — Seniors already enrolled in St. Charles County’s property-tax relief program will not receive an annual renewal form with their 2026 bill because renewal is now automatic.

Collector Michelle McBride says staff will instead use property records, obituaries and random audits to maintain eligibility. More than 25,000 seniors are enrolled. Last year’s combined savings exceeded $5 million; this year’s total will not be known until bills are generated.

The county also plans secure tax-payment boxes at seven library branches December 8–30: Augusta, Boone’s Trail, Corporate Parkway, Deer Run, Kisker Road, Spencer Road and WingHaven. They will accept checks and money orders during library hours. Cash must not be placed inside.

Bills are expected in the mail by December 1, with online amounts available earlier. Payments become delinquent January 1, 2027. McBride cautions that initiating a bank payment on December 31 does not ensure it will process that day.

Homeowners whose mortgage escrow pays real-estate taxes will still receive an informational bill. The library option supplements existing payment methods; it does not replace them.
