How Are Bexar County Property Taxes Calculated?
Understanding how Bexar County property taxes work starts with a straightforward formula. Your tax bill equals your property’s tax appraised value, minus any exemptions, multiplied by the combined tax rate from all local taxing entities.
In Bexar County, the combined tax rate from all local entities typically ranges between 2.5% and 2.9%, depending on your location. Multiple taxing entities contribute, including Bexar County, the City of San Antonio, one of several independent school districts, Alamo Colleges District, University Health System, and the San Antonio River Authority. The typical homeowner pays approximately $4,381 annually on a median home value of around $284,400, slightly above the statewide average, making it essential to understand your property tax rights.
Who Sets Your Property’s Value?
The Bexar Central Appraisal District (BCAD), formerly the Bexar Appraisal District, determines the tax appraised value of all taxable property in the county. The district updated its name effective January 1, 2026 to align with most other Texas appraisal districts. This change is administrative and does not affect the protest process.
BCAD appraises over 770,000 properties each year using mass appraisal techniques that group similar properties together and apply broad valuation formulas. While efficient, this approach inevitably overlooks individual conditions that significantly affect value, which is precisely why the protest process exists. Your property’s tax appraised value is determined as of January 1 each year.
What Does It Mean to Protest in Bexar County?
When you protest, you are formally challenging your property’s tax appraised value, the number BCAD assigns to your home that directly determines how much you owe. Texas law gives every property owner the right to dispute this number before an independent Appraisal Review Board.
The most common grounds for protest are that your tax appraised value is too high (meaning it does not reflect what your home would realistically sell for) or that your property is unequally appraised compared to similar properties in the county. In both cases, the goal is the same: ensuring your tax appraised value is accurate and fair.
If BCAD has incorrect information about your property, such as the wrong square footage or lot size, these are factual corrections that should be submitted directly to the appraisal district. Contact BCAD at (210) 242-2432 or use their Help Center to get property record errors fixed. This is a separate process from protesting your tax appraised value.
Keep in mind that you cannot protest your tax rate. Tax rates are set by local governing bodies. Protesting focuses exclusively on the tax appraised value assigned to your property.
Step-by-Step: How to File a Property Tax Protest in Bexar County
Filing a protest in Bexar County is more accessible than many homeowners realize. BCAD offers multiple filing methods, and the entire process can be completed digitally.
Step 1: Review Your Notice of Appraised Value
BCAD mails Notices of Appraised Value beginning in mid-April each year. This notice includes your property’s proposed tax appraised value, your Owner ID, and your PIN (both required to file online). If you did not receive a notice, look up your property value at esearch.bcad.org or request your credentials by calling (210) 242-2432.
Review the notice carefully. Verify that the property description, square footage, and number of rooms match your actual property. Discrepancies in these details can inflate your tax appraised value.
Step 2: File Your Protest Before the Deadline
The standard deadline for filing a Bexar County property tax protest is May 15 or 30 days after the date on your Notice of Appraised Value, whichever is later. If May 15 falls on a weekend or holiday, the deadline extends to the next business day.
You can file online through the BCAD Online Services Portal using your Owner ID and PIN. You can also file by email (protest@bcad.org), fax (210-242-2454), mail (P.O. Box 830248, San Antonio, TX 78283-0248), or in person at 411 N. Frio St.
When filing, check “Incorrect appraised (market) value” and “Value is unequal compared with other properties” to preserve your widest range of evidence options. Also check the box requesting evidence from the appraisal district.
Step 3: Choose Your Process Path
If you file online, BCAD offers two distinct options. Option 1 (Fully Digital) keeps all communication and settlement discussions within the portal, with BCAD reviewing your protest within 10 days. Option 2 (Hybrid) lets you file online but handle the rest through phone, Zoom, or written communication. Choose whichever approach fits your comfort level.
Step 4: Gather and Submit Your Evidence
Strong evidence is the backbone of any protest. After filing, upload supporting documents through the online portal. Accepted formats are PDF and JPEG, with a maximum of 10MB per file and 20MB total. Upload within seven days of receiving your confirmation email for timely review.
Step 5: Attend Your Hearings
BCAD will review your evidence and may offer a settlement. In Bexar County, informal hearings take place by Zoom or phone (no in-person informal meetings are currently planned). If you reach an agreement, your protest is resolved.
If no settlement is reached, your case moves to a formal hearing before the Appraisal Review Board (ARB), an independent citizen panel. You can attend in person, by phone, or via Zoom.
What Evidence Strengthens a Property Tax Protest in Bexar County?
Building a compelling case requires more than disagreeing with your tax appraised value. The ARB bases its decisions on documented evidence, so preparation matters. Here is what experienced, licensed professionals focus on when building a strong protest case.
Sales comparables (market value argument). Identify homes similar to yours that sold recently for less than your tax appraised value. Look for sales within a one-mile radius with similar square footage, lot size, age, and condition.
Equity comparables (unequal appraisal argument). Find properties similar to yours that are appraised at lower values per square foot. This shows that your tax appraised value is unfairly high compared to similar properties in the appraisal district’s own records.
Property condition documentation. Gather repair estimates from licensed contractors for any issues that negatively impact your home’s value, such as foundation problems, roof damage, aging systems, or deferred maintenance. Documented evidence of condition issues carries significant weight.
Appraisal card review. Request your property’s appraisal card from BCAD and verify every detail, including square footage, number of bedrooms and bathrooms, lot size, and any listed improvements. Inaccurate records directly inflate your tax appraised value.
One critical reminder: do not simply compare your property’s value to your neighbor’s and assume yours should match. BCAD evaluates dozens of data points and adjusts each one based on individual property characteristics. A surface-level comparison without proper adjustments can hurt your case. This is where local, licensed tax professionals add significant value, because they understand how to adjust comparable data to build the strongest possible argument.
How Do Exemptions Affect Your Property Tax Bill in Bexar County?
Exemptions work separately from the protest process but are equally important. Texas voters approved significant property tax relief in November 2025 through constitutional amendments that increased exemption amounts, retroactive to the 2025 tax year.
Current Exemption Amounts for Bexar County Homeowners
The general homestead exemption now removes $140,000 from your property’s taxable value for school district tax calculations. This increase from the previous $100,000 amount was approved through Proposition 13 and saves the typical homeowner approximately $490 annually in school taxes alone.
The over-65 and disabled homeowner exemption now provides an additional $60,000 beyond the standard homestead exemption, up from the previous $10,000. Combined with the general homestead exemption, eligible seniors and disabled homeowners can exempt a total of $200,000 from school district taxes.
Disabled veterans may qualify for exemptions ranging from $5,000 to complete exemption of their property’s value, depending on their disability rating as determined by the U.S. Veterans Administration.
Homeowners can apply for exemptions as soon as they purchase their home. File Form 50-114 with BCAD through their online portal or by mail. If you already have a homestead exemption on file, it renews automatically each year unless your deed changes or your eligibility status changes.
Exemptions reduce your taxable value after the protest process concludes. That means protesting your tax appraised value and filing for exemptions work as complementary strategies that together produce the lowest possible tax bill.
Why Should You Protest Your Property Taxes Every Year?
Many homeowners only think about protesting when their tax appraised value jumps dramatically. But the reality is that protesting annually is the only way to know with certainty whether you are being fairly taxed. Even if your value appears reasonable on the surface, mass appraisal methods can still produce an inflated number that only becomes apparent after a thorough review of the evidence.
Every time you reduce your property’s tax appraised value through a protest, you lower the baseline BCAD uses the following year. This creates a compounding effect over time, especially when combined with the 10% homestead cap on annual increases. Skipping even a single year allows inflated values to compound unchecked.
Protesting carries zero risk. Texas law prohibits the ARB from increasing your property’s value during a protest hearing. The only possible outcomes are that your value stays the same or goes down.
Be cautious of any company that promises specific savings before reviewing your property. No one can legally guarantee a particular reduction, and companies that lead with big savings estimates may not be committed to taking your case through the full protest process. The best approach is to work with professionals who protest your property every year, take it through the entire process from filing through formal hearings, and give you a definitive answer about whether your tax appraised value is fair.

Frequently Asked Questions About Protesting in Bexar County
Can I protest if I didn’t receive a notice?
Yes. You can file a protest even without receiving a notice. Look up your property’s appraised value on BCAD’s property search page and file by May 15. Contact BCAD at (210) 242-2432 to request your Owner ID and PIN for online filing.
What happens if I miss the May 15 protest deadline?
Texas law does allow late protests for “good cause,” but approval is rare and far from guaranteed. Appraisal districts have significant discretion in deciding what qualifies, and most late filings are rejected. The safest approach is to treat the May 15 deadline (or 30 days after your notice date, whichever is later) as firm. If you are concerned about missing the window, consider signing up with a property tax professional early in the season so your protest is filed well before the cutoff.
Do I need to hire a professional to protest my Bexar County property taxes?
You are not required to hire anyone. However, the process requires time, research, and familiarity with how appraisal evidence and adjustments work. When evaluating professional help, look for companies with local, licensed representatives who commit to protesting your property through the entire process, including formal hearings, regardless of the expected outcome. That full commitment is the only way to get a definitive answer about whether your tax appraised value is fair.
Will protesting increase my property taxes?
No. Under Texas law, the Appraisal Review Board cannot raise your property’s value as a result of a protest hearing. The only possible outcomes are that your value stays the same or goes down.
