FAQ

When is the Collin County property tax protest deadline for 2026?

May 15, 2026, or 30 days after CCAD mails your Notice of Appraised Value, whichever is later. Use the mail date printed on the notice and confirm the account on collincad.org.

How do I file a CCAD protest?

File Comptroller Form 50-132 (or the taxpayer-portal equivalent) with Collin Central Appraisal District. Use onlineportal.collincad.org when your notice includes portal credentials. Save the confirmation—creating a login is not a filed protest.

Is this the same as Collin County informal hearing tips?

No. This guide covers the 2026 deadline, Form 50-132 filing, and city-matched comps. Informal staff-meeting tactics are in the separate Collin County informal hearing tips article.

Does Protestly file my Collin County protest for me?

No. Protestly generates a comparable sales evidence packet you can upload to CCAD or bring to informal review or the ARB. You remain in control of the protest.
