You Can Challenge Your Property Value in Galveston County Each Year

Every spring GCAD mails a notice of appraised value. If the number looks too high, you can protest it with the Appraisal Review Board, an independent panel that hears disputes. You do not need a lawyer or a paid agent; plenty of owners handle it themselves with a few recent comparable sales off the same street. The fastest route is GCAD's own taxpayer portal at portal.galvestoncad.org, where you create an account, pull up your parcel, and file the protest electronically instead of mailing a form.

Watch the deadline printed on your notice. GCAD's recent cutoff has landed on a Friday in mid-May (May 16 for 2026), and the office runs a drive-thru drop-off the morning of the deadline for paper protests. The appraisal office is in Texas City at 9850 Emmett F. Lowry Expressway, Ste. A101, not on the island, and you can reach it at 409-935-1980. ARB hearings can be done in person or virtually, so you don't have to drive to Texas City to make your case. If you still disagree after the ARB rules, you can appeal to court. Start at galvestoncad.org for the current forms and deadline.
