2024 Oil Spill Liability and Superfund Tax Per Gallon Breakdown by Blend


The 2024 “Oil Spill Liability Trust Fund Fee” will remain at 9cts/bbl (0.0021cts/gal). That rate is in effect from January 1, 2021, and through December 31, 2025.

The Superfund tax was reinstated beginning 1/01/23 and is adjusted annually for inflation. The inflation adjusted rate for 2024 is $0.26 cents per barrel of crude beginning 01/01/2024. The tax is paid by refiners and crude oil importers. Refiners and importers pass the tax down as a cost folded into the wholesale rack price of petroleum products and not as a tax. While some downstream marketers break out the Superfund rate on invoices or contract bids, they are not required to do so. In fact, it is best not to break the per gallon superfund rate out on invoices and contract bids because it creates confusion among downstream tax-exempt parties who believe they are not required to pay it. However, tax exempt parties must pay the superfund rate because it is a cost not a tax once product passes the refinery gate. The Superfund rate is not refundable to any party along the petroleum refining and distribution chain.
