Collin CAD Agent Portal

To submit your protests, please use the new Agent Appeals website:
AgentAppeals.CollinCAD.org

On the new Agent Appeals website, you can:

• Submit Protests on both authorized & non-authorized properties
• Upload your protest & hearing evidence
• Accept Appraisal District Settlement Offers
• View/Download Appraisal District Evidence
• Maintain Appointment-of-Agent Authorizations

To submit your protests electronically, you will need a user account associated with your agency. If you do not already have a user account, you will need your Agent ID and eFile PIN. Both of these are located on the Appraisal Notices that were mailed to your office.
