How to File a Property Tax Protest Online in Bexar County (2026 Step-by-Step Guide)

Key Takeaways

BCAD offers two distinct online filing paths — Option 1 is 100% digital with no phone calls or meetings, while Option 2 files online but conducts informal hearings by phone or Zoom. Both start at bcad.org/online-portal/.
The protest deadline is May 15 or 30 days after your notice is mailed, whichever is later. Missing it forfeits your right to protest for the entire tax year unless you qualify for a late filing.
You need your Owner ID and PIN from your Notice of Appraised Value to file online. If you lost yours, call BCAD at 210-242-2432 — but the deadline will not be extended while you wait.
Upload evidence within 7 calendar days of filing. BCAD accepts only PDF or JPEG files, 10MB per file, 20MB total, and a maximum of 10 photos.
Bexar County protesters won 99.1% of informal hearings in 2024, saving a combined $60 million. The odds are overwhelmingly in your favor.
The reappraisal reprieve is new for 2025–2026 — if you win your protest, BCAD will not increase your market value the following year (unless you make improvements). One successful protest now protects you for two years.
The appraisal district bears the burden of proof, not you. Under Texas Tax Code § 41.43, BCAD must establish your property's value by a preponderance of evidence.

Decision guide

BCAD gives you two ways to file your protest online. Choose the path that matches how you want the process to work.

If you are protesting for the first time and feel uncertain, Option 2 lets you talk to a BCAD appraiser directly during the informal hearing — a good way to understand the process. If you want speed and simplicity, Option 1 handles everything through email with no scheduling required.

Filing deadline and what happens if you miss it

The standard protest deadline is May 15 or 30 days after the date printed on your Notice of Appraised Value, whichever is later. If May 15 falls on a weekend or holiday, the deadline moves to the next business day. The cutoff is midnight on the deadline date.

BCAD mailed 2025 notices starting April 11, 2025, to over 390,000 property owners. When the 2026 notices arrive (typically early to mid-April), the clock starts.

Late filing is possible but limited. If you miss the deadline, you can file a late protest for "good cause" — but only before the ARB certifies the appraisal records, typically around July 20. Late protests must use a paper form (not the online portal), and the ARB decides whether your reason qualifies. Do not count on this as a backup plan.

The deadline will not be extended while you wait for your Owner ID and PIN. If you do not have your login credentials when your notice arrives, call BCAD at 210-242-2432 or email csefile@bcad.org immediately. Do not wait until the last week.

Step-by-step: filing your protest online

Step 1 — Log in to the BCAD online portal

Navigate to bcad.org/online-portal/ and click through to the login at bcadonline.org. Enter your Owner ID and PIN, both printed at the top of your Notice of Appraised Value. Select your property using your Owner ID or Property ID.

Properties with multiple owners or undivided interest (UDI) are not eligible for online filing — you will need to use a paper Form 50-132 instead.

Step 2 — File your protest and select your reason

Click "File Protest" (or select "E-File Protest" from the upper left menu). On the E-File Protest Information screen, select the reason(s) you disagree with the appraised value.

Critical strategy: Check "incorrect appraised (market) value AND/OR value is unequal compared with other properties." Selecting both grounds preserves your widest evidence presentation rights and keeps all appeal options open. This is the Texas Comptroller's own guidance — do not limit yourself to a single argument.

Enter optional comments and your Opinion of Value — your best estimate of what the property is actually worth based on recent comparable sales. Then click Submit and review the Create Protest Summary screen.

Step 3 — Choose your processing option

This is where you pick between the two digital paths:

Option 1 — E-File and Complete Entire Process Online. BCAD reviews your protest 10 days after submission. Settlement offers arrive by email. If you accept, the protest closes. If no agreement is reached, a formal ARB hearing is scheduled automatically. No phone calls, no meetings, no scheduling.

Option 2 — File Protest Only and Communicate Directly. Your protest is filed online, but the informal hearing happens by phone, Zoom, or written communication. BCAD sends a letter by mail with instructions for scheduling your informal meeting. Residential property owners can self-schedule through the Appointy app. You must reschedule at least 72 hours in advance.

Step 4 — Upload your evidence within 7 days

After filing, you have 7 calendar days to upload evidence via the Evidence View tab in your Protest Summary. This deadline starts when you receive the protest confirmation email.

What to upload: Recent comparable sales (closed sales of similar nearby homes), photographs of property condition or defects, contractor repair estimates, an independent appraisal if you have one, and documentation of any errors in your property description (wrong square footage, lot size, or year built). For unequal appraisal arguments, include the assessed values of comparable properties to show your home is appraised higher than similar ones.

What happens after you file

The informal hearing

For Option 1 filers, BCAD reviews your protest 10 days after submission. A settlement offer arrives by email. You can accept or reject it — no verbal communication occurs during the process. If you reject the offer or no agreement is reached, you move to a formal ARB hearing automatically.

For Option 2 and paper filers, a letter arrives by mail with instructions for scheduling a phone or Zoom meeting with a BCAD appraiser. There are no in-person informal meetings. BCAD can provide sales data, equity information, property descriptions, and calculation worksheets — typically within 3–5 business days for single-family properties.

The informal stage resolves the vast majority of protests. Of 185,670 accounts protested in Bexar County in 2024, over 90% settled during the informal hearing.

The formal ARB hearing

If the informal stage does not resolve your protest, it moves to the Appraisal Review Board — an independent panel of 45 citizens, not BCAD employees. Hearings are conducted before a three-member panel (you can request a single-member panel) and typically last 15–20 minutes.

Hearing format options:

Telephone conference call
Zoom/videoconference
Written affidavit (Form 50-283)
In person

Indicate your format preference on the protest form at least 10 days before the hearing. Bring evidence on paper or USB drive — smartphones are not accepted for evidence presentation.

You may reschedule a formal hearing one time without explanation as long as you notify at least 24 hours before. Missing a hearing without cause results in dismissal, with a 4-day window to request reinstatement.

In 2024, 92% of Bexar County ARB hearings resulted in a reduction for the property owner.

In 2024, Bexar County homeowners protested 185,670 accounts (24% of all parcels), saving a combined $60 million — $51 million at the informal level and $9 million through ARB hearings. The ARB success rate was 92%.

Your legal rights under Texas Tax Code

Texas law gives property owners substantial protections during the protest process. Knowing these rights changes the dynamic of every interaction with BCAD.

The burden of proof is on BCAD, not you

Under Texas Tax Code § 41.43, the appraisal district bears the burden of establishing your property's value by a preponderance of evidence. If the district fails to meet this burden, the protest is determined in your favor. You do not have to prove your home is overvalued — BCAD has to prove it is not.

The burden becomes even higher (clear and convincing evidence) when your property is valued at $1 million or less and you provide a certified appraisal at least 14 days before the hearing, or when your value was lowered in the preceding tax year.

The 14-day evidence disclosure rule

Under § 41.67(d), any evidence you requested from BCAD that they did not deliver at least 14 days before your hearing cannot be used against you. Request your evidence package early — this is one of the most powerful tools available to property owners.

Key rights at a glance

The 2025–2026 reappraisal reprieve

Starting in 2025, any property owner who successfully protests and gets their market value reduced will not see a market value increase the following year — unless improvements are made. This applies to the 2025 and 2026 tax years only.

This is the single biggest reason to protest this year. A successful protest now effectively locks in your reduction for two years instead of one, eliminating the most common homeowner complaint: having to re-fight valuations annually.

Important caveat: The freeze applies to market value, not the appraised value or your tax bill. Tax rates set by local entities can still change, and homestead cap calculations still apply. But the baseline number BCAD uses as your property's market value will not increase.

Under the 2025–2026 reappraisal plan, any property owner who successfully protests and receives a valuation reduction will not see a market value increase in the following year unless improvements are made to the property.

Post-ARB appeal options

If the ARB rules against you, the process does not end there. Texas law provides three additional levels of appeal.

You cannot pursue both binding arbitration and a district court appeal simultaneously. For most residential homeowners, binding arbitration is the more accessible and cost-effective option if the ARB does not deliver a satisfactory result.

Alternative filing methods

If you cannot or prefer not to file online, BCAD accepts protests through these channels:

Why you should protest: the numbers

The data is unambiguous — protesting works, and not protesting leaves money on the table.

$134MEstimated savings left unclaimed by 497,508 Bexar County homeowners who did not protest in 2024

In 2024, only 24% of Bexar County parcels were protested. The 497,508 homeowners who did not protest left an estimated $134 million in potential savings unclaimed — an average of $269 per household. Over 2022–2024, cumulative unrealized savings reached $344 million.

The average savings per successful protest was $1,290 in 2023. At Bexar County's combined tax rate of roughly 2.3%, a $50,000 reduction in assessed value saves approximately $1,150 per year — every year until the value is reassessed upward.

BCAD's own data confirms systematic over-assessment. In 2025, approximately 40% of Bexar County homes were assessed at values higher than actual market prices based on 2024 sales data. SABOR MLS data shows average sale prices declining while BCAD appraisal values continued to rise 2.1% — widening the gap between assessed values and market reality.

497,508 Bexar County homeowners did not protest in 2024, leaving an estimated $134 million in potential savings on the table. Cumulative unrealized savings from 2022 to 2024 reached $344 million.

Common questions

Can I file a property tax protest online in Bexar County?

Yes. BCAD offers online protest filing through its Online Services Portal at bcad.org/online-portal/. You need your Owner ID and PIN from your Notice of Appraised Value to log in. The system offers two paths: Option 1 handles the entire process digitally (no phone calls or meetings), while Option 2 files online but conducts the informal hearing by phone, Zoom, or written communication. Properties with multiple owners or undivided interest are not eligible for online filing and must use a paper Form 50-132.

What evidence do I need to protest my property taxes in Bexar County?

The strongest evidence includes recent comparable sales (closed sales of similar nearby homes), photographs documenting property condition or defects, contractor repair estimates, and documentation of errors in your property description such as incorrect square footage or year built. For unequal appraisal arguments, include the assessed values of comparable properties to show yours is appraised higher than similar homes. BCAD accepts only PDF or JPEG files, with a maximum of 10MB per file, 20MB total, and 10 photos. You must upload evidence within 7 calendar days of receiving your protest confirmation email.

What is the deadline to file a property tax protest in Bexar County?

The deadline is May 15 or 30 days after the date printed on your Notice of Appraised Value, whichever is later. If May 15 falls on a weekend or legal holiday, the deadline moves to the next business day. The cutoff is midnight on the deadline date. Late protests may be accepted for good cause if filed before the ARB certifies the appraisal records (typically around July 20), but late protests cannot be filed online — they require a paper form delivered by mail or in person.

Can the ARB raise my property value if I file a protest?

No. In residential protest cases, the ARB cannot raise your property value above the amount on your Notice of Appraised Value. The worst outcome of filing a protest is that your value stays the same. There is no risk of your value increasing because you protested. Additionally, under the 2025–2026 reappraisal reprieve, a successful protest locks in your reduced market value for the following year as well — making the upside of protesting even greater.

What happens if I miss my protest deadline?

You may be able to file a late protest if you can demonstrate good cause to the ARB. Late protests must be submitted before the ARB certifies the appraisal records, which typically happens around July 20. Late filings cannot be done online — you must use a paper Form 50-132 and deliver it by mail or in person. The ARB decides whether your reason qualifies as good cause. Do not rely on this as a backup plan — file before the deadline whenever possible.

Is it worth protesting my property taxes in San Antonio?

The data strongly supports protesting. In 2024, the informal protest success rate in Bexar County was 99.1%, and 92% of formal ARB hearings also resulted in reductions. The average savings per successful protest was $1,290 in 2023. Approximately 40% of Bexar County homes were assessed above actual market prices in 2025, meaning a large share of homeowners have legitimate grounds for a reduction. With the 2025–2026 reappraisal reprieve, a successful protest now protects your value for two years.

Do I need to hire someone to protest my property taxes?

No. Texas law allows any property owner to protest on their own behalf at no cost. The online filing process is straightforward, and the burden of proof is on the appraisal district to justify your value — not on you to prove it is wrong. However, licensed Texas real estate agents can also represent property owners under the TREC exemption (Texas Occupations Code §1152.002(a)(8)), which can be helpful for homeowners who want expert comparable sales analysis and hearing representation without navigating the process themselves.
