Relating to adjustments in the appraised value of a residence homestead.

HB 4191 modifies Texas property tax rules for homestead residences (primary homes). It allows appraisal offices to adjust a home's taxable value annually based on specific formulas, rather than solely using current market value. For properties with rising values, the adjustment caps at 3% of the prior year's value plus the prior year's value plus new improvements. For properties with falling values, it calculates a proportional decrease from the prior year's value plus new improvements. The bill affects Texas homeowners with homestead exemptions and takes effect September 1, 2025.
