Assessment Appeals

The property taxes you pay are based on your property’s assessed value, as determined by the County Assessor.  If you feel that your property value is less than the Assessor’s value, you have the right to appeal that value to your local Assessment Appeals Board by filing an Assessment Appeal Application. We have provided information below to guide you through the Assessment Appeal process.
