Modifies provisions relating to local sales tax law exemptions

HB 1162 expands Missouri's local sales tax exemptions for specific business inputs. It exempts physical goods, energy, and materials used in manufacturing, processing, mining, or producing products (Section 2), and adds exemptions for defense contractors (Section 3), commercial laundries meeting volume thresholds (Section 5), and construction materials for nuclear security enterprises in large cities (Section 6). The nuclear exemption (Section 6) is temporary, expiring August 28, 2034. This bill directly affects manufacturers, defense contractors, broadcasters, and large-scale laundries by reducing their tax burden on qualifying business supplies.
