How property tax appeals work in Bexar County
Every Texas homeowner has a right to protest their assessed value under Texas Property Tax Code §41.41. In Bexar County, protests are handled by the Bexar Appraisal District (BCAD). The deadline is May 15, 2027, or 30 days after your appraisal notice was mailed, whichever is later.
BCAD has both online and in-person protest options. San Antonio market values rose sharply 2022-2025, many homeowners are still overassessed relative to actual sale prices.
The strongest protests include 3-7 comparable sales from the last 12 months in your immediate neighborhood, adjusted for square footage, age, and condition. San Antonio-area assessors typically reduce values when presented with clear, recent comp data.
Bexar County is one of the counties in our Texas Over-Assessment Study, where we ran millions of homes through the same unequal-appraisal comparison the BCAD uses. You can check your own address free in 30 seconds, or read our full methodology first.
