How to protest your property taxes in San Antonio

1

Check whether your assessed value is too high

Compare your appraised value to what similar homes nearby actually sold for recently. If your number sits above those comparable sales, you likely have a case — and that, not the tax rate, is the part you can actually fight.

2

Know your Texas deadline and process

Texas mails your Notice of Appraised Value in the spring, and you protest it with your county Appraisal District. The deadline is usually May 15 — or 30 days after your notice is mailed, whichever is later. You start with an informal review, then a formal Appraisal Review Board (ARB) hearing if you don't settle. Mark the date — miss it and you wait a year.

3

Gather your evidence

The strongest evidence is recent comparable sales of similar nearby homes priced below your assessment, plus anything that lowers your home's value — needed repairs, condition issues, photos. Bring specifics, not opinions.

4

Make your case

Start with the informal review — many protests are resolved right there. If not, present your comps and condition evidence at the formal hearing. Stay factual and organized.

5

Re-file next year if needed

Assessments reset every year, so protesting is something you can do annually. A win this year doesn't lock in next year's value.
