TPT; prime contracting; senior housing

HB 2075 amends Arizona's tax code to change how prime contractors calculate their tax base, not to address senior housing (the title appears misleading). It sets the tax base at 65% of gross income for prime contracting businesses, with specific deductions allowed for items like land sales, groundwater equipment, furniture, and certain environmental cleanup work. Key provisions include deductions for contracts in military reuse zones, environmental remediation projects, and machinery/equipment installations with "independent functional utility." The bill directly affects construction companies and manufacturers qualifying for these tax deductions but does not create new housing programs or impact senior housing.
