San Antonio isn't appraised by one single office — its city limits cross county lines. Here's which appraisal district actually covers your address, what exemptions you can claim, and your protest deadline.

San Antonio is one of the few major Texas cities whose limits sit almost entirely inside a single county — nearly all of it is in Bexar County, appraised by the Bexar Appraisal District (BCAD). The one exception is a small piece of the city's far north side, up near Stone Oak, that crosses into Comal County and is appraised by the Comal Appraisal District instead.
Not sure which one applies to you? Look up your address on BCAD's site first (bcad.org) — if your property doesn't show up there, try the appraisal district for whichever neighboring county your address is closest to. Your most recent tax bill will also say which appraisal district and which taxing units apply to your specific parcel.

Exemptions are set by state law, so they're the same everywhere in Texas — San Antonio included. The only thing that changes depending on which county your address falls in is which appraisal district you file with:
File Form 50-114 (homestead) or Form 50-135 (disabled veteran) with whichever appraisal district covers your specific address — it's free, no company needs to be paid to do this for you, and you can still file up to two years late if you missed the window. See our full property tax exemptions guide for every dollar amount and edge case.
You have until May 15, or 30 days after your appraisal district mails your Notice of Appraised Value — whichever is later — to file a protest, regardless of which of San Antonio's counties your address is in. Each appraisal district mails notices on its own schedule, so go by the date printed on your own notice rather than assuming May 15 applies to you. File Form 50-132, usually through your appraisal district's own online portal. There's no fee, and no attorney is required.
Protesting in San Antonio costs nothing to do yourself — the process above is the same whether or not you hire anyone, no matter which county's appraisal district you're filing with.
