Supporting Energy and Economic Development (SEED) Act
To amend the Internal Revenue Code of 1986 to extend biodiesel and renewable diesel incentives, and for other purposes.
Summary
The Supporting Energy and Economic Development (SEED) Act extends federal tax incentives for biodiesel and renewable diesel through December 31, 2029, beyond their currently scheduled expiration date of December 31, 2024. The bill extends the biodiesel mixture credit, biodiesel credit, and excise tax credits for biodiesel and renewable diesel fuel, as well as payments for fuels not used for commercial purposes. The legislation prevents entities from claiming multiple tax credits for the same fuel by establishing that biodiesel credits cannot be claimed if the fuel also qualifies for the clean fuel production credit under another section of the tax code. The amendments apply to fuel sold or used on or after the date of enactment of the legislation.
