OK HB4458

Amends the definition of "qualifying manufacturing concern" for Oklahoma's five-year ad valorem tax exemption to allow establishments engaged in mechanical or chemical transformation of materials to qualify even without a manufacturer exemption permit under Section 1359.2, provided they otherwise meet the statutory requirements

Clarifies that the constitutional requirement for an existing facility to be unoccupied for 12 months prior to acquisition applies only to initial exemption eligibility, not to continuation of the exemption in subsequent years of the five-year period

States legislative intent that these amendments are a clarification of prior law rather than a change to existing law

Effective date: November 1, 2026
