San Antonio is one of the most affordable major metros in Texas—but that doesn't mean your property taxes are low. Bexar County property values have been climbing steadily, and so have tax bills.

The good news: Bexar County property owners who protest their assessments have a strong track record of success. About 78% of formal protests result in some reduction, with average savings of $850 per year.

Here's everything you need to know to protest your San Antonio property taxes in 2026.

Bexar County Property Tax Landscape

The Bexar Appraisal District (BCAD) manages over 700,000 properties across San Antonio and surrounding areas. While more affordable than Austin or Dallas, Bexar County has seen steady appreciation:

Bexar County Statistics:
  • Properties: 700K+
  • Average Assessment: $275,000
  • Year-over-Year Increase: 7.8%
  • Protest Success Rate: 78%
  • Average Savings: $850/year
With an average 7.8% increase and a 78% success rate, many San Antonio homeowners have legitimate grounds for protest.

2026 Deadlines

May 15, 2026 (Standard Deadline)

File your protest with BCAD by this date. Miss it and you're locked out for the entire tax year.

30 Days After Notice (If Later)

If your appraisal notice arrives after April 15, you get 30 days from the notice date.

Timeline

  • April 2026: BCAD mails notices
  • May 15, 2026: General deadline
  • May-July 2026: Informal hearings
  • July-September 2026: ARB hearings

Step-by-Step: How to Protest in Bexar County

Step 1: Check Your Appraisal Notice

When your notice arrives, verify:

  • Property address and legal description
  • Square footage and lot size
  • Building characteristics (bedrooms, bathrooms, etc.)
  • Listed improvements and amenities
  • Current vs. prior year values
Errors in BCAD's records are common. A simple square footage correction can justify a reduction without much argument.

Step 2: Evaluate If Protesting Makes Sense

Signs you should protest:
  • Assessment increased more than 8-10%
  • Your $/sqft exceeds similar nearby sales
  • You know of property issues BCAD doesn't
  • Recent comparable sales support a lower value
  • Your property has been over-assessed in prior years
Signs protesting may not pay off:
  • Assessment is at or below recent purchase price
  • Your neighborhood has genuinely appreciated significantly
  • No comparable sales support your position

Step 3: File Your Protest

Online (Recommended): File through BCAD's online portal. Fastest method with immediate confirmation. By Mail: Bexar Appraisal District P.O. Box 830248 San Antonio, TX 78283-0248 In Person: 411 N. Frio St. San Antonio, TX 78207

Select "Value is over market value" as your protest reason—it's the most common and usually strongest argument.

Step 4: Gather Evidence

BCAD appraisers need data, not opinions. Build your case:

Comparable Sales (Most Important)

Find 3-5 properties that:

  • Sold in the past 12 months
  • Are within your neighborhood or 1 mile
  • Are similar in size (within 20%)
  • Are similar in age and condition
  • Sold for less than your assessed value
Property Condition Issues

Document problems affecting value:

  • Foundation concerns
  • Roof damage or age
  • Outdated major systems (HVAC, plumbing, electrical)
  • Needed repairs with estimates
  • Flood zone location
BCAD Record Errors

Check your property card for:

  • Wrong square footage
  • Incorrect room count
  • Listed amenities you don't have
  • Wrong construction quality rating
  • Incorrect year built

Step 5: Attend Your Informal Hearing

Before formal ARB proceedings, BCAD offers informal hearings to resolve protests.

What to expect:
  • 15-30 minute meeting
  • Present your evidence to a BCAD appraiser
  • Opportunity to negotiate
  • Most protests are resolved here
Tips for success:
  • Bring organized, printed evidence
  • Lead with your strongest comparable sales
  • Stay professional and fact-focused
  • Know your target value before walking in
  • Be prepared to negotiate

Step 6: ARB Hearing (If Needed)

If informal discussions don't work out:

  • Formal hearing before the Appraisal Review Board
  • More structured with sworn testimony
  • Present your evidence systematically
  • Board makes a binding decision
Most homeowners can represent themselves effectively with good preparation.

What Evidence Works in San Antonio

Tier 1: Strongest

  • Comparable sales at lower values — Similar properties that sold for less than your assessment
  • Appraisal errors — Incorrect property characteristics in BCAD's records

Tier 2: Strong

  • Property condition documentation — Foundation reports, repair estimates, photos
  • Recent market data — MLS showing prices, days on market

Tier 3: Supporting

  • Unequal appraisal — Similar properties assessed lower
  • Location factors — Busy street, flood zone, other negatives

San Antonio Neighborhood Considerations

North Central (Stone Oak, TPC, Champions)

Higher-value properties with more assessment variation. Strong comps are essential—focus on finding similar sales.

Northwest (Helotes, Leon Springs)

Mix of older and newer construction. Condition-based arguments may work for older homes.

Northeast (Schertz, Cibolo)

Parts are in Guadalupe County (different CAD). Verify which appraisal district covers your property.

South Side

More affordable properties where smaller dollar reductions still represent meaningful percentage savings.

Downtown/Midtown

Urban properties with unique characteristics. Comps may be harder to find—be creative but stay similar.

Alamo Heights, Terrell Hills, Olmos Park

Independent cities within Bexar County. Same BCAD, but these areas have distinct market conditions.

Common Mistakes San Antonio Protesters Make

1. Missing the Deadline

May 15 is absolute. Set calendar reminders starting in April.

2. Using Online Estimates

Zillow and similar estimates aren't evidence. BCAD won't accept them. Use actual closed sales.

3. Poor Comparables

A 1960s home doesn't compare to 2015 construction. Match property type, age, and condition.

4. Emotional Arguments

"I can't afford this" or "This isn't fair" won't help. Stick to data.

5. Not Checking BCAD Records

Simple errors in square footage or amenities are easy wins. Always review your property card.

Special Considerations

Military Installations

San Antonio has multiple military bases. If you're military personnel with deployment or relocation, you may have additional protections and deadlines.

Historic Properties

King William, Monte Vista, and other historic districts may have unique valuation considerations.

Flood Zones

Parts of San Antonio are in flood zones. If your property is flood-prone, that affects value and should be part of your argument.

Investment Properties

Rentals don't benefit from the 10% homestead cap. YoY increases can be substantial, making protests more valuable.

After Your Protest

If Successful:
  • Reduced assessment = reduced taxes
  • The reduction typically carries forward
  • Consider protesting annually
If Unsuccessful:
  • Your value cannot be raised during protest
  • Options: binding arbitration, district court (rarely worth it for residential)
  • Try again next year with updated evidence
