Top Mistakes San Antonio Homeowners Make When Protesting Property Taxes

Every year, thousands of San Antonio residents take a stand against high property tax appraisals by filing a protest with the Bexar Appraisal District. And every year, many of those homeowners walk away frustrated—not because they didn’t have a valid case, but because they made avoidable mistakes during the protest process. In this article, we break down the most common pitfalls and how to avoid them so you can make the strongest case possible in 2025.

Mistake 1: Missing the Protest Deadline

The number one mistake San Antonio homeowners make is simply missing the deadline to file a protest. BCAD typically sends out appraisal notices in April, and the deadline to protest is either May 15 or 30 days from the date the notice was mailed—whichever is later. Missing this date means forfeiting your right to challenge your property’s assessed value for the year.

How to avoid it: Mark your calendar, subscribe to reminders, or better yet—sign up for notifications with Ballard Property Tax Protest so you never miss a deadline again.

Mistake 2: Not Gathering Proper Evidence

Too many homeowners rely on vague arguments like “my taxes are too high” or “this can’t be right.” Unfortunately, those won’t help your case. BCAD is only concerned with whether the market value of your home was properly assessed.

Effective evidence includes:

  • Comparable sales ("comps") of similar homes in your neighborhood
  • Photos of damage, deferred maintenance, or poor condition
  • Independent appraisals
  • Repair estimates from licensed contractors

Mistake 3: Focusing on the Tax Bill Instead of the Appraisal

Many property owners walk into their hearing and start talking about how their taxes have increased dramatically. But it’s important to understand: BCAD doesn’t set your tax rate—only your property value. Tax rates are determined by taxing entities like school districts, cities, and counties.

Your focus should be: Is the appraised market value accurate for your property? Is BCAD’s data correct?

Mistake 4: Skipping the Informal Meeting

The informal review with a BCAD appraiser is your first opportunity to reach a resolution. It’s less formal than the Appraisal Review Board hearing and often more flexible. Many successful protests are resolved at this stage.

Why it matters: If you skip this step, you may miss a chance to reduce your appraisal without a formal hearing, which can be more intimidating and time-consuming.

Mistake 5: Using the Wrong Comparables

Just pulling Zillow listings of nearby homes won’t cut it. BCAD uses strict criteria when analyzing comps, and so should you.

Avoid these comp mistakes:

  • Using sales from after January 1 (they won’t be considered)
  • Using homes from different neighborhoods
  • Comparing against homes that are larger, newer, or renovated

Mistake 6: Being Unprepared for the ARB Hearing

If your case goes to the ARB, you’ll be presenting before a panel of citizens appointed to hear protests. This process is more formal than the informal meeting and requires a clear, well-documented presentation.

Tips to succeed:

  • Organize your documents logically
  • Focus on facts, not emotions
  • Practice a short summary of your argument

Bonus Mistake: Going It Alone

Navigating the property tax protest process is not easy—especially if you're not familiar with BCAD’s systems, standards, or strategies. While it’s legal to represent yourself, many homeowners leave money on the table due to lack of experience.
