Relating to the treatment for ad valorem tax purposes of the residence homestead of a totally disabled veteran.

HB 4434 amends Texas Tax Code sections to provide property tax relief for totally disabled veterans who own a homestead. The bill changes how tax refunds are calculated when veterans qualify for an exemption during a tax year (rather than waiting until the next year), allowing them to receive prorated refunds based on the number of days they qualified. Specifically, it revises Section 26.10(b) to establish a formula that subtracts taxes owed with and without the exemption, then applies a daily fraction for the qualifying period. This directly affects disabled veterans who move or qualify for the exemption mid-year, ensuring they only pay taxes for the portion of the year they were ineligible. The bill focuses on clarifying the tax calculation process, not expanding eligibility.
