Why Bexar County homeowners should protest every year
The Bexar County Appraisal District (BCAD) appraises over 680,000 properties across the San Antonio metro area. Like every large Texas appraisal district, BCAD uses mass appraisal models to estimate property values. These models work with averages and neighborhood-level trends, which means individual homes routinely get mispriced. A home with deferred maintenance, a smaller lot, or an unfavorable location within the subdivision can easily be appraised above what the data supports.
In 2024, 185,670 protests were filed in Bexar County. Of the 140,213 resolved at the informal hearing stage, 139,075 resulted in a value reduction. That is a 99.19% informal win rate. Not 80%. Not 90%. Over 99%. For comparison, Dallas County's informal win rate was 51.5% during the same period. Bexar County stands out because its informal hearing process is structured to find agreement rather than create friction.
The total value reduced through informal hearings was $16.1 billion. That money went back to Bexar County homeowners as lower tax bills. The system is not adversarial. BCAD appraisers at the informal stage are looking for reasons to adjust values when the evidence supports it.
If you own property in Bexar County and have not protested, the data says you are leaving money on the table. The informal process is fast, the win rate is extraordinary, and the only requirement is that you file on time and bring reasonable evidence.
Bexar County key dates for 2026
The protest calendar follows the statewide Texas pattern, but there are Bexar-specific details around BCAD's online portal and hearing scheduling that are worth tracking.
Early April: Preliminary values posted on bcad.org
BCAD typically posts preliminary appraised values on their website before mailing official notices. You can look up your property by address or account number at bcad.org. This early access window gives you time to research comparable properties before the formal protest clock starts.
Mid-April: Notices of Appraised Value (NOAVs) mailed
BCAD mails NOAVs to all property owners in mid-to-late April. Your NOAV shows your market value, assessed value, exemptions, and the protest deadline. Read it carefully and compare it to what you see on bcad.org. For help decoding the notice, see our guide to the Notice of Appraised Value.
May 15: Protest filing deadline
Under Texas Tax Code Section 41.44, you must file your protest by May 15 or 30 days after the date your NOAV was mailed, whichever is later. For most Bexar County homeowners, the effective deadline is May 15. File through BCAD's E-File portal or mail Form 50-132. The online portal tends to get heavy traffic close to the deadline, so filing early avoids headaches.
May through September: Informal hearings and scheduling
After filing, BCAD schedules your informal hearing. You can choose in-person, phone, or video conference. Hearings run from late May into September depending on volume. Given the 99.19% informal win rate, most protests are resolved at this stage without needing a formal ARB hearing.
Do not miss the deadline
May 15 is a hard deadline. If you miss it, you lose your right to protest for the entire 2026 tax year. There are limited late-filing exceptions under Tax Code 41.44(b), but they require demonstrating good cause — military deployment, medical emergency, or similar circumstances. Do not rely on exceptions. File on time. For the full list of county deadlines, see our 2026 protest deadline calendar.
Understanding your Notice of Appraised Value
Your NOAV from BCAD contains three distinct values that serve different purposes in your tax calculation. Understanding the difference between them is essential before you file, because you protest only one of them and the other two are determined by formulas you cannot directly challenge.
Market value
This is BCAD's estimate of what your property would sell for as of January 1, 2026. BCAD uses mass appraisal models to value over 680,000 properties across the San Antonio metro, from downtown and the King William District to Alamo Heights, Stone Oak, and the growing suburbs along the 1604 corridor. In 2024, BCAD mailed notices to 390,000 property owners whose appraised value increased by $1,000 or more. The market value is the number you protest.
Net appraised value (capped value)
If you have a homestead exemption, Texas Tax Code §23.23 limits the annual increase in your appraised value to 10% over the prior year's appraised value, plus the value of any new improvements. This cap matters in neighborhoods like Alamo Heights, Terrell Hills, and parts of North San Antonio where market values have been rising faster than 10% annually. The gap between your market value and capped value is real money — but you still want the market value as low as possible to limit future increases.
Taxable value
This is the capped value minus all applicable exemptions. Your NOAV shows which entities are taxing your property: Bexar County, the City of San Antonio (or another municipality), the San Antonio River Authority, Alamo Colleges District, the Bexar County Hospital District, and your local school district (SAISD, NEISD, NISD, or others). The City of San Antonio increased its homestead exemption from 10% to 20% in 2023, and state Proposition 4 added a $100,000 school district exemption. Both reduce your taxable value below the capped value.
Which value should you protest?
You protest the market value. Lowering the market value reduces everything downstream: the capped value and the taxable value. Even if the 10% homestead cap means a market value reduction does not change your taxes this year, it narrows the gap between market and capped values — which limits how much BCAD can raise your taxes in future years. For a full explanation of this dynamic, see our cap-gap guide.
How to file through BCAD's online portal
BCAD's E-File system is the quickest way to file your protest. The process takes about 10 minutes from start to finish. Here is a step-by-step walkthrough.
Go to bcad.org and search for your property
Visit bcad.org and use the property search. You can search by address, owner name, or account number. Your account number is on your NOAV and prior tax bills. Pull up your property detail page and review the current appraised value, square footage, and property characteristics. Make sure the data is accurate — errors in square footage or condition ratings are common and worth flagging in your protest.
Navigate to the E-File protest option
From your property detail page, find the protest or E-File option. BCAD's interface lets you initiate a protest directly from your property record. If the option is not yet available for 2026, check back after NOAVs are mailed in April. You may need to create a brief account or verify your identity as the property owner.
Select your protest reason
Choose the grounds for your protest. We recommend selecting "The appraised/market value of my property is unequal compared to other properties" (unequal appraisal) as your primary reason. You can also check "The appraised/market value of my property is too high" (market value exceeded). Selecting both covers you for the strongest arguments at your hearing. For a detailed explanation of each ground, see our complete Texas protest guide.
Upload evidence (be mindful of file size limits)
BCAD's E-File allows you to upload supporting documents, but there are strict file size and format restrictions. Keep your uploads concise: a one-page comp grid, a condition summary, and a few photos if relevant. If your evidence packet is large, consolidate it into a single PDF under the size limit. You can also bring printed evidence to your hearing. Uploading early gives BCAD staff time to review before your hearing date.
Submit and save your confirmation
After submitting, you will receive a confirmation with a tracking number. Save it. The tracking number lets you check the status of your protest and see your scheduled hearing date. BCAD will notify you of your hearing time by email or mail. Keep an eye on both.
If you prefer to file on paper, download Form 50-132 from comptroller.texas.gov and mail it to BCAD at P.O. Box 830248, San Antonio, TX 78283-0248. Use certified mail so you have proof of timely filing.

That is a 99.19% informal win rate — the highest among major Texas counties. Virtually every homeowner who made it to an informal hearing received a value reduction. The total value reduced informally was $16.1 billion.
ARB (formal) hearing results
Went to ARB
28,906
Resulted in Reduction
19,730
Of the protests that were not resolved informally and went to the Appraisal Review Board, 68.2% resulted in a reduction. The ARB is a tougher environment than the informal hearing, but the majority of protesters still come away with a lower value. The ARB reduced a total of $3.1 billion in assessed value.
What these numbers mean for you: If you file a protest in Bexar County and show up to your informal hearing with any reasonable evidence, the historical data says you have a 99.19% chance of getting a reduction. Even if you go to the ARB, you still have a 68.2% chance. No other major Texas county comes close to this informal win rate. For a statewide comparison, see our success rates by county analysis.
Why Bexar's 99% informal win rate matters
A 99.19% informal win rate is not normal. Harris County sits at 88.6%. Dallas County is at 51.5%. Bexar County is in a different category. Understanding why changes how you approach your protest.
BCAD's informal hearing process is structured to reach agreement. Appraisers at the informal stage have authority to make adjustments based on the evidence presented. When a homeowner brings comparable properties showing a lower per-square-foot value, the appraiser can evaluate the data and offer a reduction on the spot. The process is designed to resolve cases, not to defend the original appraised value at all costs.
This also reflects the volume of protests relative to BCAD's capacity. With 185,670 protests filed and over 140,000 moving through the informal pipeline, BCAD has a strong incentive to settle cases efficiently. Hearings that end in agreement avoid the cost and time of ARB proceedings. Both sides benefit from resolution at the informal stage.
What this means strategically
- Filing is the hardest part. The data says that if you file and show up, you are overwhelmingly likely to get a reduction. The barrier is not the hearing itself — it is getting your protest submitted on time.
- Even a basic case wins. You do not need 15 perfect comps and a professional appraisal report. Five to eight comparable properties with lower per-sqft values is enough to give the BCAD appraiser something to work with.
- Skipping the protest is the worst decision. In a county where 99% of informal hearings produce a reduction, not filing is the equivalent of volunteering to overpay.
The contrast with Dallas County is worth noting. Dallas has a 51.5% informal win rate, which means the outcome is close to a coin flip. In Bexar County, the question is not whether you will get a reduction — it is how much. That changes the calculus entirely. Even if you are busy, even if you have never done this before, the 10 minutes it takes to file through BCAD's E-File portal is worth the near-certain payoff.

Even with a 99% informal win rate, better evidence leads to larger reductions. The appraiser can only adjust your value based on what you present. Weak evidence might get you a token $2,000 reduction. Strong evidence built on comparable properties can get you $15,000 or more.
Finding comparable properties on bcad.org
BCAD's public property search at bcad.org is your primary research tool. Search for properties near your home and review their appraisal details. You are looking for 5 to 10 homes that are similar to yours in size, age, and condition, but are appraised at a lower per-square-foot value.
Start with your subdivision
BCAD appraisers give the most weight to properties in your immediate subdivision. Search for homes on your street and surrounding streets. For each property, note the appraised value and living area square footage. Calculate the per-square-foot value by dividing the appraised value by the square footage.
Match key characteristics
Good comps match your home on square footage (within 20%), year built (within 10 years), number of stories, and overall condition. A 2,000 sqft home built in 2010 compared to a 2,200 sqft home built in 2012 is a solid comparison. A 1,400 sqft home from 1970 compared to a 3,200 sqft home from 2022 is not.
Focus on lower per-sqft values
This is the core of the unequal appraisal argument. If your home is appraised at $160 per square foot and you can show 5 to 8 similar homes at $130 to $145 per square foot, that gap is your case. Calculate the median per-sqft value of your comps — that number is what you should argue your home should be valued at.
Document condition issues
If your home has condition problems — an aging roof, foundation movement, outdated systems, or cosmetic wear — document them with photos and repair estimates. BCAD may have your home rated in better condition than it actually is. Correcting the condition rating alone can produce a meaningful reduction.
BCAD's evidence upload limits
BCAD's E-File system has strict file size and format restrictions for uploaded evidence. Keep your files small and focused. A single-page comp grid PDF, a brief condition summary, and a handful of compressed photos should fit within the limits. If your evidence exceeds the upload restrictions, consolidate to the most important items for upload and bring the full packet to your hearing in printed form.
Our toolkit does this automatically. Enter your Bexar County address and our system pulls your property data directly from BCAD records, identifies comparable properties in your neighborhood, calculates your per-sqft equity position against the median, and generates a formatted evidence packet ready for your hearing. It takes 30 seconds instead of 3 hours of manual research. Try it free.
Condition-based evidence that BCAD appraisers take seriously
Comparable properties are your primary argument, but condition-based evidence can add meaningful weight when your property has issues that BCAD's mass appraisal did not capture. BCAD appraisers and ARB panels recognize three categories of condition-based value reduction.
Deferred maintenance
Physical deterioration that reduces your home's value below what BCAD's models assume. Roof damage or aging past useful life, HVAC systems needing replacement, plumbing issues, foundation movement, or water damage all qualify. Document each issue with dated photos and contractor estimates. BCAD assigns your home a condition rating, and if that rating does not match reality, the appraised value is wrong. A $15,000 foundation repair estimate directly supports a lower market value argument.
Functional obsolescence
Design or layout issues that reduce market appeal relative to what buyers expect at your price point. San Antonio has an enormous range of housing stock — from 1920s bungalows near downtown and the King William District to 2020s construction in the Far West Side and Cibolo Canyons. A home with a single bathroom in a neighborhood where comps have two, an outdated galley kitchen where open-concept is standard, or a converted garage that reduced bedroom count all represent functional obsolescence that mass appraisal cannot detect from exterior data.
External obsolescence
Factors outside your property that reduce its value. Proximity to JBSA-Lackland or JBSA-Randolph flight paths, the Loop 410/I-10/I-35 interchange, railroad tracks in older South and East Side neighborhoods, or adjacency to commercial development that generates noise or traffic all qualify. These are location-based value detractors that your comparable properties may not share. If nearby homes at the same per-sqft value are not under a flight path but yours is, that difference justifies a lower appraised value.

Hearing tips for Bexar County
The informal hearing is where the vast majority of Bexar County protests are resolved. You meet with a BCAD staff appraiser and present your evidence. In Bexar County, you have the option to attend in person, by phone, or by video conference. Choose whichever format works best for you — the outcome data does not show a meaningful difference between formats.
Given the 99.19% win rate, the informal hearing in Bexar County is less about whether you will get a reduction and more about how much. Here is how to make sure you get the best result.
Choose your hearing format based on your situation
BCAD offers three options: in-person at their offices, phone, or video conference. Phone hearings are fastest and require no travel. In-person hearings let you hand over printed evidence directly and have a more natural conversation. Video splits the difference. If you have straightforward comp-based evidence, phone works fine. If you need to walk through condition photos or complicated data, in-person or video may be more effective.
Have your evidence organized before the hearing
BCAD appraisers handle a high volume of hearings. Print your comparable properties in a clean table — address, square footage, year built, appraised value, and per-sqft value for each comp. One page, easy to scan. The appraiser will compare your comps against their data. Organized evidence speeds up the process and helps you get a better offer.
Know your target number going in
Before the hearing, calculate the median per-sqft value of your comps and multiply it by your home's square footage. That is your target value. If the appraiser offers something close to that number, accept it. If the first offer is well above it, explain your comp data and ask the appraiser to review the specific properties you identified.
Lead with unequal appraisal
Start with the equity argument: your per-sqft appraised value is higher than comparable properties in your neighborhood. This argument has the clearest legal standard under Texas Tax Code and BCAD appraisers are accustomed to evaluating it. Market value is your secondary argument if equity alone does not fully close the gap.
Stay factual and polite
The BCAD appraiser did not set your value personally. They are reviewing the data to see if an adjustment is warranted. Present your numbers clearly, explain your reasoning briefly, and let the data do the work. With a 99% win rate, the system is working in your favor. Do not create friction where none is needed.
For word-for-word scripts covering what to say during your opening, how to present comps, and how to respond to appraiser questions, read our hearing scripts guide. We also have a guide on understanding the cap-gap — which matters if the appraiser says a reduction will not change your taxes this year.
Should you hire an agent or do it yourself?
In Bexar County, 148,350 out of 185,670 protests were filed by agents or consultants in 2024 — that is 79.9%. The tax protest industry has a large presence in the San Antonio metro, with firms handling thousands of protests each season.
But Bexar County is arguably the best county in Texas for DIY protesters. The 99.19% informal win rate means the process is designed to produce reductions. You do not need professional-grade negotiation skills or insider connections. You need reasonable comparable properties and 10 minutes to file. The agent-filed rate reflects convenience, not necessity.

We generate your evidence packet from BCAD data: comp grid, per-sqft analysis, filing walkthrough, and hearing scripts. You file and attend the hearing, but with professional-grade evidence. You keep 100% of savings.
Tax Agent
25–50% of savings
The agent handles everything: filing, evidence, hearing, negotiation. No upfront cost usually, but they take 25% to 50% of your first-year savings. On a $25,000 value reduction saving you $600, the agent takes $150 to $300.
The best choice depends on your time and comfort level. In Bexar County specifically, the case for DIY or our toolkit is stronger than in any other major Texas county — because the win rate is so high that the agent's negotiation skill is less of a differentiator. For a detailed comparison, see our DIY vs. consultant breakdown. You can also use our decision framework to figure out which option fits your situation.
What happens if the informal hearing does not work
Given the 99.19% informal success rate, most Bexar County protesters never need to go beyond the informal stage. But if you and the BCAD appraiser cannot reach an agreement, your protest advances to the Appraisal Review Board (ARB).
In 2024, 28,906 Bexar County protests went to the ARB. Of those, 19,730 resulted in a value reduction — a 68.2% success rate. The ARB reduced a total of $3.1 billion in assessed value. These are strong numbers. Even at the formal hearing level, the odds favor the protester.
The ARB hearing is more structured than the informal meeting. You present your evidence to a panel of appointed citizen members. BCAD presents their evidence and reasoning for your current value. The panel deliberates and issues a binding determination. The same evidence that works at the informal stage — comparable properties with lower per-sqft values, condition documentation, clear presentation — works at the ARB. Our hearing scripts include specific language for ARB presentations.
Most Bexar County homeowners find resolution well before reaching the ARB, and the data strongly supports that outcome. But if the ARB rules against you, Texas law provides three additional appeal paths.
If the ARB denies your protest: what comes next
An unfavorable ARB determination is not the end. The ARB must send you a copy of its order by certified mail, and that order starts the clock on three separate appeal options. Each has different costs, timelines, and rules.
Binding arbitration
Available for residential homesteads regardless of value, and for non-homestead properties appraised at $5 million or less by the ARB. You must file a request for binding arbitration with the Bexar County Appraisal District within 60 days of receiving the ARB's order of determination.
File using Comptroller Form AP-219 along with a deposit payable to the Comptroller of Public Accounts. The deposit amount depends on the ARB-determined value: $450 for properties under $500,000, $550 for $500,000 to $1 million, $750 for $1 million to $2 million, $1,050 for $2 million to $3 million, and $1,550 for $3 million to $5 million. An independent arbitrator hears the case and issues a binding decision, typically within 20 days of the hearing.
If the arbitrator rules in your favor, you receive a refund of your deposit minus $50 retained for administrative costs. If the arbitrator rules against you, the deposit pays the arbitrator's fee. Arbitration can only address market value for real property — it cannot address exemptions, agricultural appraisal, or other non-value issues.
District court appeal
You may file a petition with the district court within 60 days of receiving the ARB's order. This is a full judicial proceeding heard in Bexar County district court. Court costs and attorney fees make this the most expensive option, but it provides the broadest scope of review. District court appeals are most practical for high-value properties where the potential tax savings justify the legal expense.
State Office of Administrative Hearings (SOAH)
For properties with an ARB-determined value of $1 million or more, you can appeal to SOAH instead of district court. File with the Bexar County Appraisal District within 30 days of receiving the ARB order. The deposit is $1,500. SOAH hearings shift the burden of proof: the appraisal district must establish the property's value by a preponderance of evidence, rather than you having to disprove their number. This is a meaningful procedural advantage for homeowners with properties in the $1 million-plus range.
Tax payments during appeal
Regardless of which appeal path you choose, you must continue paying property taxes while the appeal is pending. You are required to pay the amount of taxes due on the portion of taxable value not in dispute, or the amount due under the ARB's order, or the amount due in the previous tax year, whichever applies. If the appeal results in a reduction, Bexar County will issue a refund for any overpayment.
