Galveston County homeowners are overpaying property taxes.
Filing Deadline
May 15, 2026 (41 days left)
According to Galveston Central Appraisal District certified property rolls (Texas Tax Code §25.19), every residential property must be appraised at 100% of market value each year. The appraisal district determines your home’s appraised value using recent comparable sales, property characteristics, and neighborhood trends — which directly sets your tax bill. If the district overestimates your home’s worth, you overpay, and that compounds over time.
However, Texas homeowners with a homestead exemption benefit from a 10% annual cap on assessed value increases. This means your assessed value cannot rise more than 10% over the prior year’s assessed value, regardless of how much the market value increases. As a result, the appraised value (what the district says your home is worth) and the assessed value (the capped figure used for taxation) can diverge significantly in rapidly appreciating markets.
Under Texas Tax Code §41.43(b)(3), homeowners can challenge their appraisal on two distinct grounds. The first is market value — arguing that the appraised value exceeds what your home would actually sell for. The second is unequal appraisal — demonstrating that your property is assessed higher than comparable homes in your neighborhood. Furthermore, you can present both arguments simultaneously, which strengthens your overall case at the informal hearing with GCAD.

Additionally, the protest process in Texas is straightforward and designed for homeowners to represent themselves. Here is the step-by-step process for filing through GCAD.
Enter your address on our site to compare your assessed value against neighboring properties. Our analysis identifies whether your home is overvalued relative to comparable sales in your area, which forms the foundation of a strong protest.
Our $49 evidence packet includes comparable property sales within your neighborhood, a detailed assessment analysis, and filing instructions tailored to your local appraisal district. In contrast to generic online tools, our packet identifies the specific comparable properties most likely to support a reduction. One-time fee — no recurring charges, no contingency. You keep 100% of your savings.
Submit your notice of protest through GCAD Online Protest before the May 15 deadline. You can also file by mail or in person at the appraisal office. Online filing is the fastest and provides immediate confirmation.
The appraisal district will schedule an informal hearing where you meet one-on-one with an appraiser. Bring your evidence packet — according to the Texas Comptroller’s Biennial Operations Survey, the majority of protests are resolved at this informal stage without ever reaching the Appraisal Review Board (ARB).
“The informal hearing is where most Texas homeowners win their reduction. Coming prepared with comparable properties from your own neighborhood is the single most effective strategy.” — Texas Property Tax Appeal
Not all approaches to protesting your property tax assessment are equal. The table below compares the three most common options available to homeowners.
| Approach | Cost | Your Effort | You Keep |
|---|---|---|---|
| Do Nothing | $0 | None | Overpay every year |
| Hire a Consultant (O’Connor, Ownwell) | 25–50% of savings/year | Minimal | 50–75% of savings |
| DIY with Our Evidence Packet | $79 one-time | ~2 hours | 100% of savings |
In other words, a consultant’s ongoing percentage fee can exceed the cost of our one-time evidence packet within the first year — and you retain every dollar of your reduction going forward.
Below are the most common questions homeowners ask about the property tax protest process in the county.
The protest deadline is May 15. You must file your protest with GCAD by this date or within 30 days of receiving your notice of appraised value (NOAV), whichever is later. Under Texas Tax Code §41.44, late filings are generally not accepted unless you can demonstrate good cause.
You can file online through GCAD Online Protest, by mail, or in person at the Galveston Central Appraisal District office. Online filing is the fastest option and provides immediate confirmation. Specifically, you will need to submit a completed Notice of Protest (Form 50-132) identifying the property and your grounds for protest.
The strongest evidence includes comparable property sales from your neighborhood, photographs documenting any condition issues, and an analysis demonstrating that your assessed value exceeds fair market value. For an unequal appraisal argument, you will also need assessment ratios of comparable properties. Our evidence packet provides all of these elements for $79.
For many homeowners, yes. Galveston County processes thousands of protests each year. With a $49 evidence packet, even a small reduction can save you hundreds annually.
No. Filing a protest cannot cause your taxes to increase. Your appraised value can only stay the same or be reduced as a result of the protest process. There is no financial risk to filing.
If you do not reach a satisfactory resolution at the informal hearing, you can proceed to a formal hearing before the Appraisal Review Board (ARB). The ARB is a panel of appointed citizens who will review your evidence independently. Beyond the ARB, homeowners also have the right to pursue binding arbitration or file in district court, though most cases are resolved before reaching that stage.
