Relating to the sales and use tax exemption for the repair, remodeling, or maintenance of aircraft.

HB 4085 would have expanded Texas sales tax exemptions for aircraft maintenance by removing restrictions on which aircraft operations qualify. It specifically exempted repair services, tools/supplies used in maintenance, and certain materials permanently attached to aircraft (like fuel or oil) from state sales and use taxes. This change would directly benefit aircraft repair shops, maintenance businesses, and operators (such as airlines or private aviation companies) by reducing their operational costs. The bill was withdrawn on May 5, 2025, before becoming law, so no policy changes took effect.
