TPT; prime contracting; exemption; irrigation

HB 2826 amends Arizona's tax code to expand tax deductions for prime contractors (construction businesses) by adding specific exemptions to their taxable income calculation. It directly affects contractors working on projects like environmental cleanup, groundwater monitoring devices (required under water law), and manufacturing facilities for environmental technology. Key provisions include deducting 65% of gross income for qualifying work, such as hazardous substance remediation, installation of irrigation-related groundwater devices, and construction of qualified environmental manufacturing facilities. The bill also creates a new deduction for machinery/equipment work with "independent functional utility," excluding real property modifications.
