Taxation and Finance Texas 3 Minutes Read · published February 05, 2026 Flag of Texas

In San Antonio, Texas property valuations and protests are handled through the Bexar County appraisal and Appraisal Review Board (ARB) process. This guide explains how to file a property tax protest online, what evidence to prepare, timelines for filing, and where to find official forms and hearings information. Use the Bexar County Appraisal District portal to start an online protest and to view appraisal notices and ARB schedules[1]. For state-level guidance on protest rights and appeals see the Texas Comptroller property tax resources[2]. For payment, penalties and tax collection contact the Bexar County Tax Assessor-Collector[3].

File early to preserve appeal rights.

Penalties & Enforcement

The protest process itself generally does not impose a filing fine; it is an administrative challenge to an appraisal. Specific monetary penalties that relate to property taxes (for example, penalties and interest for late payment) are administered by the county tax office. The cited official pages do not list a fee to file a protest or set fines for filing a protest; amounts and collection penalties for unpaid taxes are not specified on the cited appraisal protest pages and are handled by the tax assessor-collector.[1]

  • Deadline to file a protest: May 15 or within 30 days of the appraisal notice, as described on official guidance — see the appraisal district for the exact deadline wording.[1]
  • Filing fee: not specified on the cited page for BCAD protests.
  • Enforcer: Appraisal Review Board (ARB) administers protests; the Tax Assessor-Collector enforces tax collection and applies penalties for nonpayment.[3]
  • Escalation: ARB decisions can be appealed to district court; exact time limits for court appeals are stated in state statute and summarized on state guidance pages.
  • Non-monetary sanctions: if a protest is dismissed or you fail to appear, the appraisal stands; ARB may close the protest record.
Missing the protest deadline usually ends your review rights.

Applications & Forms

  • Owner protest form / online protest portal: consult the Bexar County Appraisal District "File a Protest" page for the online submission or printable protest form; form number not specified on the cited page.[1]

  • Hearing schedule: ARB hearing dates and scheduling procedures are posted by the appraisal district; deadlines to request a hearing are on the same official pages.[1]

How to Prepare Evidence

Gather recent comparable sales, photographs, sketch and floor plans, repair estimates, maps, and any independent appraisal reports. Submit evidence as instructed on the appraisal district portal and bring copies to the ARB hearing if requested. The appraisal district describes acceptable evidence types and submission formats on its protest information pages.[1]

  • File a protest online via the Bexar County Appraisal District portal or submit the protest form as instructed.
