IRS/Treasury Section 45Z Clean Fuel Credit: New Rules Impact Biofuel Producers
Transmission path
Regulatory change (Section 45Z rules) -> Altered eligibility and premium structure for clean fuel credits -> Impact on biofuel production costs and profitability -> Shift in feedstock sourcing and market dynamics.
Extended read
The comment period for the IRS/Treasury's Notice of Proposed Rulemaking (NPRM) on the Section 45Z Clean Fuel Production Credit has concluded, with approximately 500 stakeholders providing feedback. The proposed rules, which apply from tax year 2026 onwards, introduce several significant changes for biofuel producers. Notably, the OBBBA (presumably a related legislative act) eliminates the Sustainable Aviation Fuel (SAF) credit premium. Furthermore, the rules mandate that feedstocks must originate from the US, Canada, or Mexico starting in 2026. Non-US used cooking oil (UCO) has been deemed ineligible since January 2025 due to fraud concerns, specifically regarding palm oil blending. The regulations also aim to prevent double-dipping by excluding fuel from prior-claimed credits. These updates will directly affect the profitability and operational strategies of biofuel producers, farmers, and importers involved in the clean fuel supply chain.
