FAQ

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

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

How do I file a protest with GCAD if I lost my eFile PIN?

Email gcad@galvestoncad.org for the Owner ID and eFile PIN, or drop off/mail Form 50-132 to 9850 Emmett F. Lowry Expressway, Ste. A101, Texas City, TX 77591. The deadline is not extended while you wait for a replacement PIN.

Is GCAD informal review a separate appointment season?

Usually no. GCAD states that using the Taxpayer Portal online protest at portal.galvestoncad.org serves as your informal hearing. If you do not settle, the case is scheduled for a formal ARB in Texas City.

Does Protestly file my Galveston County protest for me?

No. Protestly generates a comparable sales evidence packet you can upload to the GCAD portal or bring to the ARB. You remain in control of the protest and any hearing.
