How to protest property taxes in Galveston County
Every Texas homeowner has a right to protest their assessed value under Texas Property Tax Code §41.41. In Galveston County, protests are handled by the Galveston Central Appraisal District (GCAD). The usual deadline is May 15 or 30 days after your appraisal notice was mailed, whichever is later. A weekend or legal-holiday deadline moves to the next regular business day. Confirm your district calendar and tax year.
GCAD waterfront and coastal properties are notoriously hard to appraise. If your home is more than 500 feet inland from comparable waterfront, you may be overpaying.
The strongest protests include 3-7 comparable sales from the last 12 months in your immediate neighborhood, adjusted for square footage, age, and condition. Galveston / League City-area assessors typically reduce values when presented with clear, recent comp data.
Galveston County is one of the counties in our Texas Over-Assessment Study, where we ran millions of homes through the same unequal-appraisal comparison the GCAD uses. You can check your own address free in 30 seconds, or read our full methodology first.
