If you own property in Bexar County or the greater San Antonio area, there's a good chance your property taxes are higher than they should be. Bexar County property values have surged in recent years, and the Bexar County Appraisal District (BCAD) has raised appraised values aggressively — often outpacing actual market conditions.
The good news? You have the legal right to protest your property tax assessment, and thousands of Bexar County homeowners successfully lower their taxes every year. In this guide, we'll walk you through everything you need to know about protesting your property taxes in Bexar County in 2026.
Why Protest Your Bexar County Property Taxes?
Property taxes in Bexar County are based on the appraised market value of your property as determined by BCAD. If BCAD's appraised value is higher than your property's actual market value, you're overpaying.
Here are common reasons Bexar County property assessments are too high:
- Rapid market changes — BCAD uses mass appraisal methods that may not reflect neighborhood-level pricing
- Property condition issues — Foundation problems, older roofs, or needed repairs that reduce market value
- Incorrect property data — Wrong square footage, bedroom count, or lot size in BCAD records
- Unequal appraisal — Your home is valued higher than comparable neighboring properties
- Market softening — Some San Antonio neighborhoods have seen prices level off or decline
💡 Did you know? The average Bexar County homeowner who protests saves between $800 and $1,500 per year in property taxes. That's $4,000–$7,500 over five years.
Key Deadlines for 2026
| Date | Event |
|---|---|
| Mid-April 2026 | BCAD mails Notice of Appraised Value to property owners |
| May 15, 2026 | Deadline to file a protest (or 30 days after notice, whichever is later) |
| May–August 2026 | Informal hearings and ARB formal hearings |
| After ARB Hearing | You can appeal to district court or binding arbitration if unsatisfied |
⚠️ Important: The May 15 deadline is firm. If you miss it, you'll have to wait until next year to protest. Don't wait — file as soon as you receive your notice.
How to File a Property Tax Protest with BCAD
Step 1: Get Your Notice of Appraised Value
BCAD mails these out starting in mid-April. You can also look up your property value online at bcad.org. Your notice will show your property's proposed market value for 2026.
Step 2: File Your Protest
You have several options to file:
- Online: Through the BCAD iFile system at bcad.org
- By mail: Send Form 50-132 (Notice of Protest) to BCAD, P.O. Box 830248, San Antonio, TX 78283
- In person: Visit BCAD at 411 N. Frio Street, San Antonio, TX 78207
- Through an agent: Authorize a professional like OverAssessed to file on your behalf
When filing, select your grounds for protest:
- "Value is over market value" — The most common and effective reason
- "Value is unequal compared with other properties" — Your home is valued higher than similar homes
- "Property description is incorrect" — Wrong data in their records
Step 3: Gather Your Evidence
Strong evidence is the key to a successful protest. For Bexar County, focus on:
- Comparable sales (comps) — Recent sales of similar homes within 1 mile of your property
- Photos of property defects — Foundation issues, old roof, needed repairs
- Equity comparisons — Show that similar homes in your neighborhood are appraised lower
- A professional appraisal — If you recently had one done (for refinancing, etc.)
- Market data — Neighborhood trends showing price declines or stabilization
Step 4: Attend the Informal Hearing
BCAD offers informal hearings before the formal ARB hearing. This is your first opportunity to negotiate. Many cases are settled at this stage. Come prepared with your evidence printed and organized.
Tips for informal hearings:
- Be polite and professional — the appraiser is doing their job
- Present your comps clearly — focus on 3-5 strong comparable sales
- Know your target value — what do you think your property is actually worth?
- Be willing to negotiate — a 5-10% reduction is a significant win
Step 5: Formal ARB Hearing (If Needed)
If you can't reach an agreement at the informal hearing, your case goes to the Appraisal Review Board (ARB). This is a panel of local volunteers who review both sides and make a binding decision.
For the formal hearing:
- You'll present your evidence to a panel of 1-3 ARB members
- BCAD will present their justification for the appraised value
- The ARB will issue a decision, usually the same day
- Hearings typically last 15-30 minutes

- Giving up too early — If the informal hearing doesn't work, go to the formal ARB hearing.
