TPT; exemption; fire apparatus

HB 2924 amends Arizona's sales tax code (Section 42-5061) to update existing exemptions from the state's retail sales tax. It specifically clarifies exemptions for medical items like insulin, prosthetics, and durable medical equipment prescribed by licensed health professionals, as well as food, nonprofit sales, and certain educational materials. The bill does not create a new "fire apparatus" exemption as implied in its title - this appears to be a mislabeling, as the actual text revises other exemption categories. The changes directly affect businesses selling these exempt items, such as pharmacies, hospitals, schools, and nonprofits, by removing tax liability on qualifying transactions. The policy update focuses on refining existing tax law, not introducing new provisions.
