If you own a home in Texas, you already know the drill. Every spring, the Notice of Appraised Value arrives in the mail, and the number is almost always higher than last year. But what many homeowners do not realize is that the appraisal district's number is not final—it is an opening offer.
Protesting your property taxes is a fundamental right in Texas, and it is the single most effective way to control your tax burden. In this guide, we will walk you through exactly how to protest your property taxes in Texas for the 2026 tax year, step by step.
Step 1: Understand the May 15 Deadline
The most critical rule of protesting property taxes in Texas is missing the deadline means you lose your right to appeal for the entire year. For 2026, the deadline to file your Notice of Protest is May 15, or 30 days after your Notice of Appraised Value was mailed to you—whichever is later.
Do not wait until May 14 to start gathering evidence. You can file your protest online through your county's appraisal district portal (such as McLennan CAD, Bell CAD, Williamson CAD, or Travis CAD) in just a few minutes. Filing early secures your place in line.
Step 2: Choose Your Grounds for Protest
When you file your protest (Form 50-132), you must select the reasons for your appeal. The two most common and successful grounds are:
- Value is over market value: You are arguing that your home would not sell for the amount the appraisal district claims it is worth.
- Value is unequal compared with other properties: This is the "Equal and Uniform" argument under Texas Tax Code §41.43. You are arguing that your home is appraised higher than similar homes in your neighborhood, regardless of market value.
Always check both boxes. The Equal and Uniform argument is often the strongest weapon a homeowner has, because it relies on the county's own data against them.
Step 3: Gather Your Evidence
You cannot win a protest by simply saying, "My taxes are too high." You must bring data. The appraisal district uses mass appraisal models; you must use specific, localized evidence.
If you are arguing market value, you need recent sales of comparable homes in your neighborhood, or repair estimates for significant damage to your home (foundation issues, roof leaks, etc.). If you are arguing Equal and Uniform, you need the assessed values of similar homes on your street.
This is where Parity Tax Engine comes in. Instead of spending hours digging through county records, Parity automatically pulls the 15 best comparable properties, adjusts for differences in square footage and age, and builds a statutory adjustment grid that proves your case.
Step 4: The Informal Hearing
After you file, you will be scheduled for an informal meeting with a county appraiser. This is a brief, one-on-one conversation where you present your evidence.
The appraiser will review your comps and may offer a settlement reduction on the spot. If the offer is fair and aligns with your evidence, you can accept it, sign a waiver, and your protest is complete. Most protests are resolved at this stage.
Step 5: The Appraisal Review Board (ARB) Hearing
If you cannot reach an agreement at the informal hearing, you will proceed to a formal hearing before the Appraisal Review Board (ARB). The ARB is an independent panel of citizens appointed to resolve disputes between taxpayers and the appraisal district.
At the ARB hearing, both you and the county appraiser will present evidence. You will have about 5 to 10 minutes to make your case. Present your comparable sales grid clearly, state your requested value, and stick to the facts. The ARB will deliberate and issue a binding decision.
The Bottom Line
Protesting your property taxes in Texas is not a lottery—it is a data-driven process. The appraisal districts are relying on mass models, but you have the advantage of knowing your specific property and neighborhood. By filing before May 15 and bringing a mathematically sound comparable analysis, you can successfully lower your appraisal and save thousands.
