OBBBA and IRA credits: Key changes for financial institutions

  • Insight
  • December 22, 2025

The One Big Beautiful Bill Act (OBBBA) brings a significant shift to the clean energy tax credit landscape, accelerating IRA credit phaseouts and imposing new foreign-entity restrictions. In this episode, Denise Schwieger and Randa Barsoum break down what these changes mean for financial institutions, from navigating the Material Assistance Cost Ratio (MACR) test to managing tighter rules around credit transferability.

For institutions active in or entering the IRA credit market, this discussion underscores the need to reassess deal structures, supply-chain exposure, and transfer diligence in light of OBBBA’s new compliance demands.

Key takeaways

  • The One Big Beautiful Bill significantly modifies the IRA credit framework—modifies or accelerates phaseouts for major credits including Sections 45Y, 48E, 45X, 45Q, and 45V.
  • New foreign-entity restrictions are a central shift, creating eligibility risks for taxpayers classified as Specified Foreign Entities (SFEs) or Foreign Influence Entities (FIEs).
  • Supply-chain sourcing becomes a decisive factor under the new Material Assistance Cost Ratio (MACR) test; sourcing inputs from prohibited foreign entities can disqualify entire credit streams.
  • Credit transferability under Section 6418 remains intact and expands to new credit types, but credits can no longer be transferred to SFEs, requiring more detailed buyer screening.
  • Financial institutions must enhance diligence processes, including supply-chain validation, ownership review, and strengthened reps and warranties in transaction documents.
  • The IRA market remains active, but OBBBA represents a “serious reset”—making compliance and risk assessment central to every deal decision.
