As of July 1, 2022, Superfund excise taxes under IRC Sections 4661 and 4671 will be reinstated and apply to all US-based operations, including those in Puerto Rico. These excise taxes were reinstated under the Infrastructure Investment and Jobs Act (IIJA).
The reach of the expanded Superfund excise taxes potentially includes industrial and consumer product manufacturers, taxpayers that historically have not been subject to Superfund excise taxes. Consequently, taxpayers in multiple sectors may be obligated to pay Superfund excise taxes on products they manufacture or import.
