What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

This bill creates a sales and use tax exemption for various items, specified in further detail in the bill, used exclusively for a qualified nuclear fusion technology project certified by the Wisconsin Economic Development Corporation. Under the bill, a “qualified nuclear fusion technology project” is a project that has the purpose of undertaking the controlled fusion of atomic nuclei or research thereupon.

Because this bill relates to an exemption from state or local taxes, it may be referred to the Joint Survey Committee on Tax Exemptions for a report to be printed as an appendix to the bill.
