What do buyers need to know before closing?
Estimate taxes from your purchase price, not from the seller's last bill. The seller's bill may reflect a homestead cap, an over-65 exemption or a tax ceiling. None of those transfer to you. A capped value generally resets to market value on January 1 after the sale.
- Taxes are typically prorated at closing, with the seller crediting you for the days they owned the home that year. Your title company calculates the exact amount.
- If you have an escrow account, your lender collects taxes monthly and pays the bill for you.
- File your own homestead exemption once you move in. Until it is in place, you are taxed like an investor.
How do I get a homestead exemption in Bexar County?
Apply to the Bexar Appraisal District (BCAD). You need a Texas driver's license or state ID showing the same address as the home. The general filing deadline is before May 1.
- It lowers taxable value. The school exemption is $140,000 statewide, and any other unit may exempt up to 20% of value.
- It caps growth in your appraised value at 10% a year, starting the year after you qualify (Texas Tax Code §23.23).
Owners 65 or older, or with a disability, get an additional $60,000 school exemption. Many local units add their own amounts.
How do I protest my Bexar County appraisal?
File by May 15 or 30 days after your Notice of Appraised Value is mailed, whichever is later. The 2026 deadline has passed. The next window opens when 2027 notices go out in the spring.
- Read your notice from the Bexar Appraisal District (BCAD). It explains how to file and gives your deadline.
- File the protest with the district, online where offered or on Comptroller Form 50-132.
- Send your evidence and review any settlement offer from the district's appraiser.
- If you do not settle, the Appraisal Review Board hears your case.

Frequently asked questions
Is there one property tax rate for all of Bexar County?
No. Each address is taxed by its own set of units. Inside San Antonio and Northside ISD the 2026 total is $2.329964 per $100. Other school districts, cities and special districts produce different totals.
Does the homestead exemption apply automatically when I buy?
No. You apply to the Bexar Appraisal District (BCAD) yourself, with a Texas driver's license or state ID showing the home's address. The general deadline is before May 1.
Can my appraised value jump after I buy a home?
Yes. The previous owner's 10% cap ends with the sale, and the value generally resets to market on January 1 of the next year. Your own cap starts the year after you qualify for a homestead.
Where do I find the exact taxing units for an address?
Search the address on the Bexar Appraisal District (BCAD) website. The property record lists every unit that taxes it, and the Bexar County Tax Assessor-Collector publishes each unit's adopted rate.
