How to protest your property taxes in Bexar County
Your Bexar County property value is set by the Bexar Appraisal District (BCAD). If your appraisal notice says your home is worth more than it would sell for — or more than similar homes on your street — you can protest it. Here's exactly how it works in Bexar County.
Filing deadline
May 15, or 30 days after your notice is delivered — whichever is later
Where to file
Look up your property
Step 1: Check your appraisal notice
Appraisal districts across Texas mail notices of appraised value in the spring, usually April. Compare the market value on your notice with recent sales of similar homes nearby. If the district's number is higher, you have grounds to protest. You can also protest if your home is appraised higher than comparable homes on your street (an unequal appraisal protest).
Step 2: File your protest with BCAD
File through the BCAD Online Services Portal (log in with your Owner ID and PIN). Protests go to BCAD, not to Bexar County.
The statewide deadline is May 15, or 30 days after your notice was delivered if that's later (Texas Comptroller). Miss it and you generally wait until next year.
Step 3: Gather your evidence
The strongest evidence is recent sales of homes like yours: similar size, age, and condition, close by, and sold near January 1 of the tax year. Add photos of anything that lowers your value (foundation issues, an old roof, needed repairs) and contractor estimates if you have them.
Bexar County tips
- Comparable sales should be no later than the first quarter of the protest year and list square footage, lot size, age, and construction.
- Upload evidence on the portal's Evidence View tab as PDF or JPEG files (20 MB total).
- Accepted evidence includes appraisals, sales contracts, certified closing statements, photos, and repair estimates.
Step 4: The informal conference
After you file, BCAD typically offers an informal meeting with an appraiser. Present your comparable sales and any condition evidence. Most protests are settled here. If the offer is fair, you can accept it and you're done.
Step 5: The ARB hearing (if you don't settle)
If you don't settle, the Appraisal Review Board (ARB) holds a formal hearing and must give you at least 15 days' notice. You can attend in person, by phone, or by video, or submit a written affidavit instead. The board weighs your evidence against the district's and issues a decision.
