The recent notice from the IRS concerning the clean fuel production credit under Section 45Z has provided vital insights for the clean fuels sector; however, it leaves several key questions unresolved. Intended to guide clean fuel producers in determining when a sale qualifies for the Section 45Z credit, the notice includes implications that could inadvertently disqualify sales made via intermediaries. This is due to the stipulation that fuel must be sold for direct use “as a fuel” in the purchaser’s trade or business.
The notice may unintentionally disadvantage producers, particularly when the sale involves transportation fuels designed for end-users rather than as intermediates in fuel production processes like ethanol-to-jet fuel conversion. A suggested amendment is for the IRS to require intermediaries to notify producers about end-users, thereby enabling producers to ensure the fuel is sold in a manner that qualifies for the Section 45Z credit. This clarification could significantly affect pricing strategies for producers of niche fuels, such as sustainable aviation fuel.
Emissions measurement is another area the notice seeks to address—with non-aviation transportation fuel producers directed to use a new emissions model developed by the Department of Energy and Argonne National Laboratory. This development aids in computing emissions scores, fundamental in valuing the tax credits. Aviation fuel producers are to continue using models from the International Civil Aviation Organization. However, the new non-aviation model does not accommodate alternative production methods, necessitating applications for provisional rates from the Department of Energy, a potentially cumbersome process.
The notice fails to offer guidance on mixed-use facilities, prompting calls for more explicit instructions, particularly concerning the anti-stacking rules that restrict claiming multiple credits for the same facility within the same year. Further clarity would support the industry in optimizing these tax incentives in their business models.
Proposed regulations accompanying the notice aim to address roles within the supply chain, asserting that the final producer of a transportation fuel—after comprehensive processing—is eligible to claim credits. These regulations also deem any fuel that can be used in highway vehicles or aircraft as transportation fuel eligible for credits, thus extending to marine fuels that meet these criteria.
While the notice underscores critical pathways for the applicability of Section 45Z credits, it underscores substantial ambiguities that the Treasury Department and IRS need to clarify. With revisions anticipated, the industry awaits refinements that will support the clean fuel sector’s readiness to apply these tax credits effectively.
