Establishes the Missouri Defense and Energy Independence Act

HB 3027, the Missouri Defense and Energy Independence Act, creates new sales tax exemptions for businesses producing critical materials (like metals for defense tech) and critical pharmaceuticals. It exempts purchases of materials, equipment, and energy used in manufacturing these items, as well as defense contractors' purchases under federal contracts and large-scale industrial laundries. The bill also exempts construction costs for nuclear security enterprises in cities over 400,000 population, with this exemption expiring August 28, 2034. These tax breaks directly benefit manufacturers and defense-related businesses in Missouri.
