This page covers the Galveston County deadline, how the process works, what evidence counts, what each option costs and where to file. Facts about Texas protest rules come from the Texas Comptroller and the Texas Tax Code, and district details come from the Comptroller's county directory and Galveston CAD's own site. We checked them on September 30, 2026.
The Comptroller says the deadline to protest is, in most cases, May 15 or 30 days after the appraisal district delivers your notice of appraised value, whichever is later (Tax Code §41.44). Read the date on your notice rather than relying on a calendar. If the last day falls on a weekend, the deadline moves to the next business day (Tax Code §1.06), which matters in 2027 because May 15 is a Saturday. Confirm the exact date with Galveston CAD when your notice arrives.
Late protests are possible only for narrow reasons, such as good cause shown before the ARB approves the appraisal records, so do not plan around them. See our Texas protest deadline guide.
The Comptroller's protest page explains each stage and the forms.
The Galveston CAD office is in Texas City, not on the island. The Comptroller's Galveston County directory listing shows the current district contact details.
A property owner can protest the value of the property, unequal appraisal, and the denial of an exemption, among other matters (Tax Code §41.41). The ARB decides on evidence, and the Comptroller notes the board cannot take your personal economic situation into account, and a protest must be about value, not the size of the tax bill. For coastal properties, the evidence that can matter includes FEMA flood-zone status, elevation, storm damage and its repairs, and insurance costs, alongside recent sales of similar homes nearby and equity comparisons. Bring documents for each point you raise.
One limit to know: if your homestead is already under the 10% appraisal cap (Tax Code §23.23), a lower market value may not change your taxable value this year. See the 10% homestead cap explained and the Comptroller's valuation page.

TaxDrop Pro covers Galveston County. If you want to hand the whole protest to a licensed agent, it is the option to compare against the other firms.
Texas property tax consultants are licensed and regulated by the Texas Department of Licensing and Regulation (TDLR). You can look up any firm on tdlr.texas.gov before you sign an agent authorization. Full pricing is on the TaxDrop pricing page.
Here is an illustration with stated assumptions, not a prediction. Say a protest lowers your value by $30,000. At the county's median effective tax rate of 1.49% (U.S. Census Bureau data; your actual rate depends on your taxing units), that is about $447 in tax savings for the year.
Because Pro's fee is based on the value reduction, not on your tax savings, it is a bigger share of first-year savings where tax rates are lower. At this example, $300 is about 67% of the first-year tax savings. Compare it with a percentage-of-savings fee using your own numbers before you choose.
According to U.S. Census Bureau American Community Survey data, compiled in the TaxDrop data center, Galveston County homeowners pay a median property tax of $4,238 on a median home value of $284,900, an effective rate of 1.49%. These are survey medians, not Galveston CAD figures, and your own bill depends on your value, exemptions and taxing units.

Protesting through GCAD's online portal counts as your informal hearing. If you don't settle, your protest goes to the ARB. If you disagree with the ARB's order, you can appeal to district court within 60 days of receiving it, or use binding arbitration or SOAH if your property qualifies.

A residence homestead gets a $140,000 school district exemption. Owners 65 or older or disabled get an additional $60,000 school exemption, and other taxing units may offer local options. Apply with GCAD on Form 50-114; the general deadline is before May 1. An exemption is separate from a protest, and you can have both.
