How to Protest Galveston County Property Taxes (GCAD)

Protest Galveston County property taxes with GCAD by May 15, 2026. Form 50-132, §41.461 evidence exchange, flood-aware comps, $29.99 packet.

Galveston Central Appraisal District (GCAD) sets the appraised value behind school, city, county, and MUD bills for Galveston Island, League City, Friendswood, Texas City, Dickinson, and surrounding mainland communities. A Galveston County property tax protest challenges that value when January 1 comps from your true coastal or inland submarket support a lower number.

File Form 50-132 by May 15, 2026, or within 30 days of the Notice of Appraised Value mail date — whichever is later. GCAD’s Taxpayer Portal accepts online filing and evidence uploads for many accounts; mail and in-person filing remain available.

Island, bay, and mainland Galveston County product rarely share the same buyers. Flood elevation, insurance cost, and storm exposure can move marketability as much as square footage — keep comps inside the same product type before you argue a countywide coastal median.

After filing, GCAD typically schedules an informal conference. Bring (or upload) your best January 1 sales then — most cases settle here. If informal review does not resolve the protest, the Galveston County Appraisal Review Board hears the same evidence formally.

Request GCAD’s §41.461 evidence packet once Form 50-132 is on file under Texas Tax Code §41.461. Review the district’s island vs. mainland comps in writing, upload supplemental League City / Friendswood or Galveston Island sales before the Taxpayer Portal deadline, and carry the same response to informal review and the ARB.

Protestly builds a flat $29.99 comparable-sales packet for Galveston County residential addresses; you still file and appear yourself. Outcomes vary and are never guaranteed.
