How Do I Protest My Property Tax Appraisal in Bexar County?

Key Deadline: In Bexar County, your protest must be filed by May 15 or 30 days after your Notice of Appraised Value is mailed — whichever is later. Missing this deadline means waiting until next year.

Property taxes are a significant expense for San Antonio homeowners, and the Bexar Appraisal District's assessed value directly determines how much you pay. If you believe your home has been over-appraised, you have the legal right to protest — and many San Antonio homeowners successfully reduce their assessed value every year, often without hiring a professional. Here's how.

Understanding the Process

Each year, the Bexar Appraisal District (BCAD) sends a Notice of Appraised Value — typically in April — showing what they believe your property is worth as of January 1. This value is used to calculate your tax bill for the current year. If the value seems too high, you protest it.

Step 1: Review Your Notice

When you receive your notice, compare the assessed value to:

• What you paid for the home (if recently purchased)
• Recent sale prices of similar homes in your neighborhood
• Your own estimate of what your home would sell for today

If the BCAD value is higher than what your home would realistically sell for, you likely have grounds for a protest.

Step 2: File Your Protest

You can file your protest in three ways:

• Online: At bcad.org — the fastest and most common method
• By mail: Mail a written protest to BCAD before the deadline
• In person: Visit BCAD at 411 N Frio St, San Antonio, TX 78207

Your protest can be based on: value being higher than market value, unequal appraisal (your home assessed higher than comparable homes), or property not qualifying for exemptions you've applied for. When in doubt, file. You can always withdraw if your evidence isn't strong.

Step 3: Gather Evidence

Evidence is everything in a tax protest. The strongest evidence includes:

• A recent appraisal from a licensed appraiser (most convincing, but costs $400–$600)
• Recent sale prices of 3–5 comparable homes (comps) in your neighborhood
• Photos of any damage, deferred maintenance, or condition issues that reduce value
• Your closing disclosure if you purchased the home recently (recent purchase price is very persuasive)
• Printouts from the BCAD website showing how your home is assessed vs. similar homes

For the comp approach, look up recent sales on Zillow, Redfin, or the BCAD sales database. Find homes similar in size, age, and condition that sold below your BCAD value. Present these as evidence that your value is too high.

Step 4: The Informal Hearing

Most protests start with an informal meeting — either in person at BCAD or via video — with an BCAD appraiser. This is an informal negotiation. Present your evidence, explain your case calmly and with data. Many protests are resolved at this stage with a reduction. If the informal offer is acceptable, you accept it and you're done.

Step 5: Formal Hearing (Appraisal Review Board)

If you're not satisfied with the informal offer, you request a formal hearing before the Appraisal Review Board (ARB) — an independent panel. You present your evidence formally; the BCAD appraiser presents theirs. The ARB makes a binding decision (subject to further appeal to district court if needed). Formal hearings are more structured but still accessible for homeowners representing themselves.

Should You Hire a Property Tax Consultant?

For most homeowners, doing it yourself is feasible and free. However, professional property tax consultants — many of whom charge only on a contingency basis (typically 30–50% of the first-year savings) — can add value in complex cases, for high-value properties, or when you simply don't have time to prepare. Companies like O'Connor & Associates, Texas Tax Protest, and local Bexar County specialists handle thousands of San Antonio protests annually.

What Kind of Reduction Can You Expect?

Results vary, but San Antonio homeowners who file well-evidenced protests commonly see reductions of 5–15% of assessed value. On a $400,000 assessed home, a 10% reduction means $40,000 less in assessed value — which translates to approximately $800–$1,000 in annual tax savings.

Don't Forget Your Homestead Exemption

Before protesting value, make sure you've applied for every applicable exemption: homestead exemption, over-65, disabled veteran, or 100% disabled veteran exemption. These exemptions can reduce your taxable value significantly regardless of the protest outcome. File at bcad.org if you haven't already.

Final Thoughts

The property tax protest process in Bexar County is accessible, fair, and worth pursuing if you believe your assessed value is above market. File on time, gather strong comparable sales data, and approach the informal hearing with a calm, data-driven case. Most San Antonio homeowners who file with good evidence achieve at least a modest reduction.
