Best Evidence for Winning a Texas Property Tax Protest (2026)

Last updated April 26, 2026 · Sources: Tax Code §41.41, §41.43, §41.461

Key insight: Unequal appraisal (§41.43(b)(3)) is typically the strongest argument because the CAD bears the burden of proving your value is at or below the median of comparable properties. This argument works even when your property genuinely appreciated — because comparable properties may not have been appraised at the same pace.

Two Grounds — Always Plead Both

File Form 50-132 with both boxes checked: "value over market" AND "value unequal." You can waive one at the hearing, but you cannot add it after the deadline.

Ground 1: Excessive Market Value (§41.41(a)(1))

Argue your appraised value exceeds what a willing buyer would pay for your property on January 1.

Strongest evidence:

Ground 2: Unequal Appraisal (§41.43(b)(3)) ⭐ Often the Winner

Argue your property's appraised value per square foot exceeds the median appraised value per square foot of a reasonable number of comparable properties.

How to build an unequal appraisal case:

  1. Pull 5–10 similar properties from your CAD's public search (same neighborhood, similar size, age, and type).
  2. For each, record: appraised value and square footage.
  3. Compute appraised value per sq ft for each property and for your subject.
  4. Compute the median (not average) of the comparables' per-sq-ft values.
  5. If your per-sq-ft appraised value exceeds the median, present this as a one-page table.

Once you present this evidence, the CAD must prove by preponderance that your value is at or below the median. In rapidly rising markets, CADs often appraise some properties faster than others — creating genuine unequal appraisal that your analysis will expose.

The HB201 Evidence Request Strategy

Under §41.461(a)(2), immediately after filing your protest, submit a written request to the CAD for all evidence they plan to present. They must deliver it at least 14 days before your hearing. If they miss this deadline, their evidence is excluded by statute (§41.67(d)).

Send the request by certified mail immediately after you receive your hearing notice. Even if the CAD does deliver their evidence, you now know exactly what you're up against before the hearing.
