Ad valorem tax protests and appeals on the ground of the unequal appraisal of property

Texas House Bill 3524, introduced in 2025, aimed to modify the process for property owners to challenge their property tax assessments on the basis of unequal appraisal. Specifically, it proposed that when a property is subject to appraisal value limitations under Sections 23.23 or 23.231 of the Tax Code, the market value determined by the appraisal district should be used to establish whether a protest should be decided in favor of the property owner. This change was intended to provide a clearer and more consistent standard for evaluating such protests.

Supporters of HB3524 argued that the bill would enhance fairness in the property tax system by ensuring that property owners have a more transparent and equitable process for contesting unequal appraisals. By standardizing the use of market value in these cases, the legislation was seen as a step toward reducing discrepancies and improving trust in the appraisal process.

Critics of HB3524 contended that the bill could complicate the appraisal process and potentially lead to increased litigation, as property owners and appraisal districts might disagree on market value assessments. There were also concerns that the changes could result in revenue shortfalls for local governments if more property owners successfully challenged their appraisals, thereby reducing the overall tax base.
