Informal Hearing vs. Formal ARB Hearing: What's the Difference?

When you file a property tax protest in Texas, you typically go through up to two distinct stages before a final decision: an informal review with appraisal district staff, and, if that doesn't resolve things, a formal hearing before the Appraisal Review Board (ARB). They're different in tone, process, and who's making the decision, and understanding both ahead of time makes you more prepared for whichever stage you end up in.

The Informal Hearing

This is a conversation, not a hearing in the courtroom sense. You (or your agent) meet with an appraiser employed by the appraisal district, sometimes in person, sometimes by phone or online depending on your CAD, and present your evidence directly to them.

What to Expect

• Relatively quick, often 15 to 30 minutes
• Less formal. No panel, no sworn testimony, no strict rules of procedure
• The appraiser has authority to agree to a reduction on the spot if your evidence is convincing
• If you don't reach an agreement, your case automatically moves to a formal ARB hearing (you don't need to refile)

Why it matters: A large share of successful protests are resolved at this stage. Appraisers see the same data you can access and are often willing to settle when your comps or unequal appraisal evidence are solid and well organized. Treat this as your best and most efficient opportunity to reach a fair number without escalating further.

The Formal ARB Hearing

If the informal review doesn't result in an agreement, your protest proceeds to a formal hearing before the Appraisal Review Board, a panel of local citizens (not appraisal district employees) who are trained to hear these cases independently.

What to Expect

• More structured: both you and an appraisal district representative present evidence, and the panel asks questions
• Testimony is given under oath
• You're generally allotted a set amount of time (often 10 to 20 minutes depending on the CAD)
• The panel deliberates and issues a written order with their decision, typically the same day or shortly after
• You have the right to request the appraisal district's evidence file in advance (often for free or a small copying fee) so you know what they intend to present

How to Prepare Differently Than for the Informal Stage

• Bring printed copies of all your evidence for the panel, not just yourself. Most ARBs expect 3 to 5 copies depending on panel size
• Practice a concise opening: what you're asking for and why, in under two minutes, before diving into the detailed evidence
• Stay factual and unemotional. Panels see a high volume of hearings and respond better to organized data than to arguments about affordability or unfairness in the abstract, even when those concerns are completely understandable
• If you requested the district's evidence file in advance, review it so you're not seeing their comps for the first time in the room

Can You Skip the Informal Stage?

In most cases, no. The informal review happens first by default when you file a protest, and it's a low cost opportunity to resolve things quickly. Some homeowners view it as a formality and go in unprepared, planning to save their real evidence for the ARB. This is generally a mistake, since a well prepared informal hearing can save you the time and effort of a formal hearing altogether.

What Happens After the Formal Hearing

If the ARB rules in your favor, the appraisal roll is updated and your tax bill reflects the new value. If the ARB rules against you, you still have further options: binding arbitration, an appeal to the State Office of Administrative Hearings, or district court, covered in our companion guides on those topics.
