HB 192 mandates a shift in Texas from appointed to elected chief appraisers for property appraisal districts. Starting in 2026, chief appraisers would be elected in the general election for state and county officers, with their terms beginning on January 1 of odd-numbered years. The bill amends various sections of the Texas Tax Code to reflect this change, sets eligibility requirements for chief appraisers, and provides standards for training and ethics. Additionally, the Texas Comptroller is prohibited from offering advisory support in matters currently under appraisal protest. The transition process includes provisions for current appraisers to serve until the new system is operational.
