How BCAD Determines Your Property Value
Mass Appraisal: 750,000+ Parcels, One Model
The Bexar County Appraisal District values 774,100 parcels using statistical models — not individual inspections. They apply blanket percentage increases by neighborhood, assuming every home on the block gained equal value. Deferred maintenance, foundation issues, an outdated kitchen? The model can't see any of it.
We pulled four verified 2025 MLS sales and compared them to BCAD's assessments. The county missed by an average of $94,000. See the data →
The 2025–2026 Reappraisal Reprieve
BCAD adopted a biennial reappraisal plan: market values may carry forward from 2025 to 2026. That means a successful protest now could lock in lower values for two years, not just one.
This is a limited window — BCAD returns to annual reappraisal starting 2027. If there was ever a year to protest, it's this one.
Your Tax Rate: Who Gets Paid
Bexar County has 66 separate taxing jurisdictions. Your combined rate depends on where you live, but a typical San Antonio homeowner pays approximately 2.03%–2.50% — double the national average. Median tax bill: $5,362.

The 4-Stage Bexar County Protest Process
Most competitors file an online form and stop at Stage 1. ATD handles all four stages.
Informal Hearing
You or your representative meet with a BCAD appraiser to present evidence. This is where most protests are resolved — approximately 88% result in a meaningful reduction.
88% success rateARB Hearing
A three-member Appraisal Review Board panel reviews your evidence in a 15–20 minute hearing. You can present comparable sales, equity data, and property condition documentation.
92% success rateBinding Arbitration
For properties valued under $5 million. Requires a $500 deposit (refundable if you win). An independent arbitrator reviews the case. Most competitors stop before this stage.
$500 deposit (refundable)District Court
The final level of appeal. Filed in Bexar County District Court. Reserved for significant disputes where all prior stages failed to reach a fair resolution.
Final appealKey Bexar County Exemptions
$140,000
School district homestead exemption (Prop 13, Nov 2025). Increased from $100,000. Retroactive to 2025. Passed with 79%+ voter support.
$200,000

Protests and exemptions stack. A successful protest reduces your assessed value. Exemptions reduce your taxable value on top of that. Combining both maximizes your savings. See all exemptions →

Frequently Asked Questions
What is the deadline to protest property taxes in Bexar County?+
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. The date on your notice matters, not the date you received it.
How do I file a protest with BCAD?+
You can file online at bcad.org (Owner ID + PIN from your notice required), by mail to PO Box 830248, San Antonio TX 78283, by fax at 210-242-2454, or in person at 411 N Frio St. Online filing offers two options: E-File (upload evidence) or File-Only (file first, submit evidence later).
What is the Bexar County protest success rate?+
Independent studies show approximately 88% of Bexar County protests result in a meaningful reduction — the highest rate among major Texas counties. At the ARB hearing level, 92% result in a reduction. Bexar County's protest rate (24.3%) is nearly double the statewide average of 12.2%.
Can BCAD raise my value if I protest?+
No. Texas Tax Code §41.43 prohibits the appraisal district from raising your assessed value as a result of a protest. The worst outcome is your value stays the same. There is zero risk to filing.
What evidence does BCAD accept?+
BCAD accepts comparable sales data, equity analyses, photos of property condition, repair estimates, and appraisal reports. For online filing, evidence must be PDF or JPEG, maximum 10MB per file, 20MB total, and no more than 10 photos. The strongest evidence includes verified MLS sales from your neighborhood within the past 12 months.
How long does the protest process take?+
The full process takes 2–4 months. Informal hearings run May through June; ARB hearings run May through July. You'll receive a written determination after each stage. If you have a representative like ATD, we handle all scheduling and appearances.
Does Alamo Tax Defense handle the entire process?+
Yes. We handle all four stages: informal hearing, ARB hearing, binding arbitration, and district court. We file the protest, build the evidence package, attend all hearings, and negotiate on your behalf. Most competitors file an online form and stop at the informal stage.
