Electric vehicle and electric battery manufacturers and critical mineral producers will want to take note of a notice of proposed rulemaking (NPRM) on Section 30D of the Internal Revenue Code of 1986, as amended, released by the Department of the Treasury and the Internal Revenue Service on March 31, 2023. The NPRM provides further guidance on the federal income tax credit relating to clean vehicles such as electric vehicles and new qualified fuel cell vehicles and the critical mineral and battery components required. Under Section 30D, new “clean motor vehicles” that meet certain requirements are eligible for up to $7,500 in tax credits.
