The Big Picture

In Texas, property owners who believe their home or business has been over-assessed for tax purposes have a formal right to challenge that assessment. Most disputes are settled through informal hearings at the local Appraisal Review Board (ARB). But when a property owner isn't satisfied with that outcome — and the property value meets certain thresholds — they can escalate to Regular Binding Arbitration (RBA).

RBA is an alternative dispute resolution process administered by the Texas Comptroller's Property Tax Assistance Division (PTAD). Instead of going to district court, the property owner and the appraisal district agree to let a neutral, certified arbitrator decide the case. The arbitrator's ruling is binding on both parties — hence the name.

Why it matters

RBA gives property owners a faster, less expensive path to contest their appraisal than litigation. For arbitrators, it's a structured, fee-based practice governed by specific state rules and timelines.

Key Parties

Every RBA case involves three core parties, plus the Comptroller's office in an oversight role.

🏠

Property Owner

The petitioner. Believes their property was appraised too high and filed a Request for Binding Arbitration (Form AP-219) after an unsatisfactory ARB hearing. The owner may be represented by a licensed Tax Agent.

🏛️

Appraisal District

The respondent. Represents the county's assessed value. Must participate and defend the appraisal once arbitration is properly invoked.

⚖️

Arbitrator

The neutral decision-maker. Certified by the Comptroller, assigned to the case by PTAD, responsible for conducting the hearing and issuing a ruling.

📋

PTAD

Property Tax Assistance Division of the Texas Comptroller's office. Administers the RBA program, assigns arbitrators, and enforces compliance with the process.

How a Case Moves Through the System

The RBA process follows a defined sequence from the moment a property owner files through the final ruling and payment. Understanding this flow is essential context for understanding what the software manages.

1

ARB Hearing & Protest Order

The property owner first protests their value at the local Appraisal Review Board. If unsatisfied with the result, they receive an Order Determining Protest — the prerequisite for arbitration.
2

Filing the AP-219 with the Comptroller

The property owner submits Form AP-219 (Request for Binding Arbitration) to PTAD along with the required arbitration deposit. Strict deadlines apply — typically 60 days from the ARB order.
3

Arbitrator Assignment

PTAD selects a qualified, available arbitrator from the Comptroller's registry and notifies both parties. The arbitrator receives the case file and begins managing the timeline.
4

Pre-Hearing & Evidence Exchange

The arbitrator establishes the hearing date and manages communication between parties. Both sides prepare and exchange evidence — appraisal data, comparables, photos, and supporting documents.
5

The Hearing

Conducted in person or virtually. Both parties present their case to the arbitrator. The format is less formal than court but governed by specific procedural rules under the Texas Property Tax Code.
6

Ruling & Award

The arbitrator enters the decision directly into the PTAD Portal, setting the final appraised value. The ruling is binding. If the property owner prevails, the CAD is responsible for paying the arbitration costs and PTAD issues the deposit refund to the property owner. If the owner does not prevail, the deposit is forfeited.
7

Payment to Arbitrator

If the property owner does not prevail, PTAD releases the arbitrator's fee from the deposit. If the property owner prevails, the CAD pays the arbitrator directly. Fee amounts are set by the Comptroller's schedule and vary by property type and value. All fee entries in the software are manual — no auto-calculation.

Key Terms & Acronyms

You'll encounter these terms throughout the codebase, documents, and case data. Learn them now.

Regular Binding Arbitration RBA

The formal alternative dispute resolution process for Texas property tax protests. The arbitrator's decision is legally binding on both parties.

Property Tax Assistance Division PTAD

The division of the Texas Comptroller's office that administers the RBA program. Not to be confused with the project name — the system being built is not affiliated with or named after this agency.

Appraisal Review Board ARB

The local panel that hears initial property value protests. An unsatisfactory ARB ruling is what gives rise to an RBA petition.

Central Appraisal District CAD

The county agency responsible for appraising all property for tax purposes. The respondent in every RBA case.

Form AP-219

The Texas Comptroller's official form for requesting binding arbitration. Property owners submit this with their deposit to initiate the RBA process.

Order Determining Protest

The decision issued by the ARB after a protest hearing and entered into the PTAD Portal. Required prerequisite for filing an RBA petition.

Arbitration Deposit

Funds submitted by the property owner with their AP-219 to cover the arbitrator's fee. Released to the arbitrator or refunded to the owner depending on the ruling outcome.

Tax Agent

A licensed representative authorized to act on behalf of a property owner in the protest and arbitration process. Tax Agents must be registered with the Texas Comptroller and may appear, file documents, and make decisions on the owner's behalf. When a case is agent-represented, the Tax Agent is typically the primary contact rather than the property owner directly.

What the Software Does

The RBA Case Management System is a custom-built workflow tool for John Gann's arbitration practice. It replaces a legacy Airtable setup and manages the full lifecycle of every RBA case — from intake through ruling and payment.

Core functions of the system
Case intake — capturing all parties, property details, and AP-219 data at case opening
File numbering — auto-assigned YYYY-### identifiers that reset each calendar year
Status tracking — cases move through defined workflow stages from intake to closed
Hearing management — dates, format (in-person vs. virtual), and outcome recording
Ruling capture — verdict type, final value, and binding decision documentation
Payment tracking — fee amounts and payment status, manually entered per Comptroller guidance
Reporting — case history and outcome summaries for the arbitrator's practice records

The system is built on Duda (web hosting) with Google Firebase Realtime Database for data storage. Google Firebase includes enterprise-grade security with role-based access rules, meaning case data is protected at the database level — only authenticated users with the correct permissions can read or write records. All case data is private to the arbitrator's practice.

An optional AI-assisted intake feature — available on a higher-cost plan and never required for normal operation — allows document images to be read and parsed automatically using the Claude API. The AI feature can be turned on or off at any time from the system settings and has no effect on any other part of the workflow.

Your role as a tester

You're helping verify that this system works correctly before it goes into active use on real cases. Understanding the RBA process gives you the context to recognize when a component is behaving correctly, when data fields make sense, and when something looks wrong. The more you understand the workflow, the better your feedback will be.
