Section 45X Credit: Final Regulations Issued
Final Regulations for the Section 45X Advanced Manufacturing Production Credit
The IRS has issued final regulations for the Section 45X advanced manufacturing production credit, a key provision of the Inflation Reduction Act (IRA). These regulations provide much-needed clarity for manufacturers seeking to claim this valuable incentive.

The Section 45X Credit: An Overview
The Section 45X credit is available to manufacturers that domestically produce and sell certain clean energy equipment in the United States between December 31, 2022, and December 31, 2032. Eligible components include solar and wind energy components, inverters, battery components (including electrode active materials [EAMs]), battery cells and modules, and applicable critical minerals (ACMs).
Key Updates in the Final Regulations
The final regulations address several significant issues, including:
Definition of “Produced by the Taxpayer”
The regulations expand upon the proposed rules, defining “produced by the taxpayer” as the substantial transformation of materials or subcomponents into a complete and distinct eligible component. Notably, both primary production (using non-recycled materials) and secondary production (using recycled materials) can qualify.
Eligible Costs of Production
The final regulations allow producers of EAMs and ACMs to include direct and indirect material costs in their production costs under certain conditions, reversing a provision in the proposed rules. They also permit the inclusion of extraction costs for raw materials sourced within the United States or its territories.
Contract Manufacturers
The regulations provide guidance on credit eligibility for contract manufacturers, allowing the parties to determine in their agreement which entity can claim the credit.
Interplay with the Section 48C Credit
The regulations clarify that property eligible for both the Section 45X and Section 48C credits can only qualify for Section 45X if it is not part of a qualified investment for the Section 48C facility.
Substantiation Requirements
The regulations introduce specific substantiation requirements for direct and indirect materials costs for EAMs and ACMs, including certifications from suppliers.
“The final regulations provide much-needed clarity for manufacturers seeking to claim this valuable incentive, but navigating the complexities requires careful planning.”
Planning for Compliance
Navigating the complexities of the Section 45X credit requires careful planning and attention to detail. Manufacturers must ensure that their sales and vendor agreements comply with the regulations and that they maintain adequate documentation to support their claims.
Important Considerations
- The future of the Section 45X credit remains uncertain due to potential policy changes.
- Manufacturers should consult with tax professionals to understand the specific requirements and implications of the regulations for their business.
By carefully reviewing these regulations and taking proactive steps to comply, manufacturers can maximize their potential benefits from the Section 45X advanced manufacturing production credit.
