Why San Antonio Homeowners Should Protest Every Year
In 2024, 185,670 Bexar County homeowners filed property tax protests — 24.3% of all parcels, nearly double the statewide average of 12.2%. Approximately 88% received a meaningful reduction, saving homeowners a combined $243 million. That's one of the highest success rates among major Texas counties.
BCAD uses mass appraisal to value 750,000+ parcels. Statistical models can't see your home's actual condition — deferred maintenance, foundation issues, a dated kitchen. They apply blanket increases that treat every home on the block the same. That's where the errors come from.
How big are the errors? We pulled four verified 2025 MLS sales in San Antonio and compared them to BCAD's assessments. The county missed by an average of $94,000. Not close. Not in the ballpark. See the data →
The homeowners who don't protest? They left $134 million on the table in 2024 — roughly $269 per household. And because Bexar County's effective tax rate is approximately 2.03% (double the national average), every dollar of overassessment costs more here than almost anywhere else.

Frequently Asked Questions
Is it worth protesting property taxes in San Antonio?+
Yes. 185,670 Bexar County homeowners protested in 2024 and approximately 88% received a meaningful reduction. Filing a protest cannot increase your assessed value — Texas law prohibits it. Even a modest reduction saves hundreds per year, every year.
Can I protest my property taxes myself?+
You can. But evidence quality determines the outcome. BCAD appraisers review thousands of protests — a stack of verified comparable sales and an equity analysis carries more weight than a general complaint. If you want to DIY, start with our guide on how to protest property taxes in San Antonio.
What happens at an ARB hearing?+
You (or your representative) present evidence to a three-member Appraisal Review Board panel. Hearings last 15–20 minutes. The panel reviews your comparable sales, photos, and equity data, then issues a determination. 92% of Bexar County ARB hearings result in a reduction.
Can my taxes go up if I protest?+
No. Texas Tax Code §41.43 prohibits the appraisal district from raising your assessed value as a result of filing a protest. There is zero risk to protesting.
How much does Alamo Tax Defense charge?+
40% of your first-year tax savings. Nothing upfront, no minimum fee, no auto-renewal. If we don't reduce your taxes, you pay nothing. Example: a $40,000 reduction at a 2.42% tax rate saves you $968 — our fee would be $387. Year 2 and beyond, you keep 100%.
What is the 2026 property tax protest deadline?+
May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Late filings with good cause may be accepted before approximately July 20, but only via paper form.
