Under current law, all sales of construction and building materials to contractors and subcontractors for use in the building, erection, alteration, or repair of structures, highways, roads, streets, and other public works are exempt from the sales and use tax levied by the state and certain local governments. Home rule cities continue to levy the tax on sales of construction and building materials within their jurisdiction. The act extends the exemption to the sales and use tax levied by home rule cities on such materials for use in connection with the building, erection, alteration, or repair of a public school. For the 2022-23 state fiscal year, the act appropriates $3,375 from the general fund to the department of revenue for use by the taxation business group. The department may use this appropriation for operating expenses related to taxation services. (Note: This summary applies to this bill as enacted.)
