A bill for an act creating sales and use tax exemptions relating to commencing or restarting nuclear electric generation facilities, and including retroactive applicability provisions.

This bill creates a sales and use tax exemption for tangible personal property, digital products, and services used to build, repair, maintain, or restart nuclear electric generation facilities in Iowa. The exemption applies to items purchased before, during, or after construction and restart activities, but excludes motor vehicles and requires facilities to provide exemption certificates to retailers. The law defines nuclear facilities broadly to include reactors, fuel storage, electrical equipment, safety systems, and environmental protection components, with eligibility requiring federal licensing and operation starting on or after January 1, 2028. Additionally, the bill includes retroactive applicability, allowing the tax exemption to apply to qualifying purchases made on or after January 1, 2025, and requires the state revenue department to issue guidance on documentation and procedures for claiming the exemption.
