Enroll in the Taxpayer Online Portal to seamlessly access your property details, opt into electronic communication from the Appraisal District, review important documents, file applications, and submit appraisal protests — all from a centralized and convenient platform.  NOTE - If you used our online services in years past, you must create a new registration this year due to us using a new eFile system for 2025.

To create a user account, you will need your Property ID and eFile PIN.  These can be found on the most recent Appraisal Notice or Exemptions Notice that was mailed to you.  Your PIN is used as your digital signature, please do not share it with anyone.  If you recently purchased a property, DO NOT use the previous owner's PIN as those are unique for each owner.  Appraisal Notices are mailed on April 15th. 

For technical assistance with this site, please create a ticket on our HelpDesk.  For any non-technical questions, please call us (469.742.9200) for assistance.  For information on how the CAD might access, collect, store, use, and/or share your personal information when you use our online services, review our Privacy Policy.
