Monthly payment options

Easy Smart Pay is a third-party monthly payment service for secured property tax. It does not apply to supplemental property tax. Credit card payments through that service have a current fee of 1.99%, while E-checks have no cost, and the rate is subject to change.
Important: Easy Smart Pay is endorsed by the Treasurer-Tax Collector but is not affiliated with Stanislaus County. Review the Easy Smart Pay information before using the service.
- Regular secured property taxes are due November 1 and become delinquent after December 10.
