New Resource: Mass Appraisal System

August 23, 2021

After receiving numerous emails from taxpayers expressing frustration with errors in data used in the Mass Appraisal System that assessors use to calculate property taxes, we have added a new resource: the Mass Appraisal System, which we hope is helpful. 

Any computerized program is only as accurate as the information entered into it. If the property identification cards have not been updated for some time this may affect the outcome of the market value for that property.

We invite you to share your experiences related to this system along with any tips you have found useful in getting changes made to your property's card by emailing us at
