How to Protest Your Property Taxes in Bexar County (2026 Guide)

If you own a home in San Antonio or anywhere in Bexar County, you have the right to protest your property tax appraisal every year — and the data strongly supports doing so. In 2024, over 185,000 Bexar County property owners filed protests, and approximately 88–99% of informal protests resulted in a value reduction with an average savings of roughly $521 per year. The 2026 protest deadline is May 15 or 30 days after your Notice of Appraised Value is mailed, whichever is later. Filing costs nothing, your value cannot increase as a result of protesting, and the process can be completed online through BCAD's E-File portal. Starting in 2026, Bexar County moves to biennial market value appraisals — meaning the value you lock in this year could be your baseline for two years, making this year's protest more important than ever.

Key Deadlines

The 2026 protest deadline is May 15 or 30 days after your Notice of Appraised Value is mailed — whichever is later.
Homestead exemption filing deadline is April 30. Make sure your homestead is on file before you protest — it affects your taxable value calculation.
Late protests may be accepted for good cause before records are certified (typically July 20), but do not count on this. File before May 15.

Why You Should Protest

In 2024, approximately 88–99% of informal protests in Bexar County resulted in a value reduction — the highest informal success rate of any major Texas county.
The average residential value reduction was roughly $19,280, translating to approximately $521 in annual tax savings.
Your value cannot increase as a result of protesting. The only outcomes are a reduction or no change. There is zero downside risk to filing.

How to File

Online: File through BCAD's E-File portal at bcad.org — the fastest method. You can upload evidence and schedule your hearing digitally.
By mail: Download Form 50-132 from the Texas Comptroller's website and mail to BCAD at P.O. Box 830248, San Antonio, TX 78283-0248. Use certified mail.
In person: Deliver your completed form to the BCAD office at 411 N. Frio St., San Antonio, TX 78207 during business hours.

2026 Special Considerations

Bexar County moves to biennial appraisals starting in 2026 — the value you lock in this year could be your baseline for two full years.
The new $140,000 school district homestead exemption (Prop 13, Nov 2025) lowers your taxable value but your assessed value still determines future caps and exemption calculations.
San Antonio's housing market saw values decline 2.5–3.9% YoY in early 2026 — BCAD assessed values may not fully reflect that correction, creating strong protest grounds.

How to file Evidence strategies What happens at the hearing Exemptions to check Step-by-step checklist FAQs

How to file: three methods, one deadline, and zero cost

BCAD's official filing guide walks through the online process step by step. The E-File portal at bcad.org is the fastest method — you can search your property, file your protest, upload evidence, and schedule your hearing entirely online. When filing, check both "Value is over market value" and "Value is unequal compared with other properties" to preserve both legal arguments for your hearing. There is no cost to file and no limit on how many reasons you select.

If you prefer paper, download Form 50-132 from the Bexar County website or the Texas Comptroller's website. Mail it to BCAD at P.O. Box 830248, San Antonio, TX 78283-0248 (use certified mail for proof of timely filing), fax to 210-242-2454, or deliver in person to 411 N. Frio St., San Antonio, TX 78207. BCAD's protest and appeal procedures page outlines all methods and your rights throughout the process.

Online (fastest): File through BCAD's E-File portal at bcad.org. Upload evidence and schedule your hearing digitally.

In person: 411 N. Frio St., San Antonio, TX 78207 during business hours.
By fax: 210-242-2454 or 210-242-2453.
Check both boxes: "Value is over market value" AND "Value is unequal compared with other properties" — preserves both legal arguments.
Cost: $0. There is no fee to file a protest. Your value cannot increase as a result.

Evidence strategies: what actually works at the informal hearing

Alamo Tax Defense's 2026 San Antonio protest guide emphasizes that the outcome depends almost entirely on the evidence you present — not arguments about tax fairness or personal financial hardship. BCAD appraisers evaluate market data. Bring data that proves your home is worth less than BCAD says.

Comparable sales (most important): Find 3–5 similar homes in your neighborhood that sold recently for less than your appraised value. Use bcad.org to search comparable properties by square footage, age, lot size, and condition. Same-subdivision comps are strongest.
Unequal appraisal data: Show that similar homes in your area are appraised lower per square foot than yours. This is a separate legal argument from market value and can win even when comps are scarce.
Property condition issues: Photos of deferred maintenance, foundation problems, aging systems (roof, HVAC, plumbing), water damage, or functional obsolescence all support a lower value. Include repair estimates from contractors if available.
Location negatives: Busy road, power lines, flood zone, commercial adjacency, or other external factors that reduce what a buyer would pay. Document with photos and maps.
2026 market correction: San Antonio home values declined 2.5–3.9% YoY in early 2026. If your BCAD appraisal did not reflect that decline, recent sales data is your strongest evidence.
Request BCAD's evidence: Check the box on Form 50-132 to request the evidence BCAD plans to use. Review it before your hearing so you can respond directly to their data.

What happens at the hearing: informal first, then ARB if needed

After filing, BCAD schedules you for two potential stages. The first is an informal settlement conference with a BCAD staff appraiser who has authority to negotiate and settle your protest on the spot. AppealDesk's Bexar County guide notes that most protests — an estimated 60%+ — are resolved at this informal stage without ever reaching a formal hearing. If the appraiser offers a value you find reasonable, you sign a settlement agreement and the protest closes immediately.

If you cannot reach agreement informally, the case moves to a formal Appraisal Review Board (ARB) hearing — a panel of independent citizens who review evidence from both you and BCAD and render a binding decision. In 2024, 92% of ARB hearings in Bexar County still resulted in a reduction. The ARB is a tougher environment than the informal conference, but the odds remain strongly in the homeowner's favor if you bring organized evidence.

Informal conference: Meeting with a BCAD appraiser (in person, phone, or video). Most protests resolve here. Come with organized evidence and a target value supported by data.
If you settle: Sign the agreement and your protest closes. The reduced value becomes your new assessed value.
ARB hearing (if needed): Panel of independent citizens reviews evidence from both sides. 92% success rate in 2024. More formal than the informal conference but still homeowner-friendly.
Further appeal: If you disagree with the ARB decision, you can pursue binding arbitration or file in district court — though this is rarely necessary for residential properties.

Exemptions to check: make sure you are not missing free savings before you protest

Before protesting your value, verify that all applicable exemptions are on file. Exemptions reduce your taxable value directly and stack on top of any protest reduction you achieve. Missing an exemption can cost you hundreds or thousands of dollars per year.

Step-by-step checklist: how to protest your Bexar County property taxes in 2026

Step 1 — Verify your homestead exemption is on file. If you have not filed for homestead, do so before April 30. This also activates the 10% cap and the new $140,000 school exemption.
Step 2 — Review your Notice of Appraised Value. Compare the appraised value to what you believe your home would actually sell for. If it is higher than market reality, you have grounds to protest.
Step 3 — Research comparable sales. Use bcad.org to find 3–5 similar homes that sold recently for less than your appraisal. Same neighborhood, similar size, similar age.
Step 4 — Document property issues. Take photos of any condition issues that reduce value: deferred maintenance, foundation cracks, aging roof, outdated systems, location negatives (busy road, power lines).
Step 5 — File your protest before May 15. Online through BCAD's E-File portal (fastest), by mail using Form 50-132, or in person at 411 N. Frio St. Check both protest reason boxes.
Step 6 — Request BCAD's evidence. Check the box on your form to receive the evidence BCAD plans to use. Review it before your hearing.
Step 7 — Attend your informal hearing. Present your comparable sales, unequal appraisal data, and property condition evidence. If the appraiser offers a fair reduction, accept and sign.
Step 8 — Go to ARB if needed. If the informal hearing does not produce an acceptable result, the case moves to the Appraisal Review Board. Bring the same evidence organized clearly. 92% of ARB hearings resulted in reductions in 2024.
Step 9 — Repeat every year. Property values change annually. Even if you received a reduction last year, your value may have increased this year. Consistent protesting is the best way to keep taxes as low as possible.

The Bottom Line

Protesting your property taxes in Bexar County is one of the highest-return, lowest-risk financial actions a San Antonio homeowner can take. Filing costs nothing, your value cannot increase as a result, the informal success rate exceeds 88%, and the average savings is roughly $521 per year. With Bexar County moving to biennial appraisals in 2026, the value you lock in this year could be your baseline for two full years — making this protest cycle more important than usual. The process takes less than an hour online, and the evidence you need — comparable sales, condition photos, and market data — is freely available through bcad.org. If you are a San Antonio homeowner and you have not protested, you are almost certainly paying more than you need to. LRG Realty helps San Antonio homeowners understand their property's market value and can provide comparable sales data that supports a well-grounded protest.

Frequently asked questions

When is the 2026 Bexar County protest deadline?

May 15, 2026, or 30 days after your Notice of Appraised Value is mailed — whichever is later. File early. Do not wait until the last day.

Is it worth protesting property taxes in San Antonio?

Yes. 88–99% informal success rate, average savings of ~$521/year, zero cost to file, and no risk of your value increasing. Over 80% of homeowners never protest, leaving millions in potential savings unclaimed.

Can my value increase if I protest?

No. Under Texas Tax Code §41.43, your assessed value cannot increase as a result of protesting. The only outcomes are a reduction or no change.

What evidence do I need?

Comparable sales (3–5 similar homes that sold for less), unequal appraisal data (similar homes appraised lower per square foot), property condition photos, repair estimates, and any location negatives. Request BCAD's evidence too.

Should I hire a company or do it myself?

Bexar County is arguably the best county in Texas for DIY protests because of the 88–99% informal success rate. You need reasonable comparable sales and less than an hour of research time. Professional firms charge 1% of the reduction or a flat fee and handle everything — worth it if you do not want to invest the time, but not necessary for a strong case.

What is the biennial appraisal change for 2026?

Starting in 2026, BCAD will only reassess market values every two years instead of annually. The value you lock in through your 2026 protest could be your baseline for two full years, making this protest cycle more impactful than usual.

Can I protest even if I did not receive a notice?

Yes. Notices are only mailed when your value increased $1,000+. You can still protest by the May 15 deadline regardless of whether you received a notice.
