Summary

This webinar, hosted by the Clean Energy States Alliance, provides a detailed overview of the material assistance rules for federal tax credits, focusing on IRS Notice 2026-15. The presenters, Seth Hanlon and Kyle Sweeney from NYU Law’s Tax Law Center, explain the background of the prohibited foreign entity (PFE) rules established by the One Big Beautiful Bill Act (OBBBA). They clarify that projects beginning construction after 2025 must calculate a material assistance cost ratio (MACR) to ensure a sufficient percentage of equipment is not produced by PFEs. The notice introduces safe harbors for identification, cost percentage, and certification, simplifying compliance for certain technologies like solar, wind, and battery storage. The webinar walks through the steps to use these safe harbors, including identifying manufactured products and components, using default cost tables, and obtaining supplier certifications. It also highlights important dates, such as the July 4, 2026, deadline for solar and wind projects to begin construction, and the distinction between the material assistance rules and other PFE rules like ownership and payments. The presenters emphasize the complexity of the rules and recommend consulting the NYU explainer for further guidance.
