Trump’s Tax Law Is Slowing Down Projects and Piling Up Legal Work

Key Takeaways

• FEOC rules require all‑or‑nothing compliance for clean‑energy tax credits
• Banks paused renewables financing due to unclear foreign‑entity ownership thresholds
• Legal due‑diligence time and fees have risen sharply under new guidance
• Developers must trace Chinese investors through multiple fund layers
• Industry expects Treasury guidance by year‑end to ease certification

Pulse Analysis

The One Big Beautiful Bill Act, signed into law last year, added a new layer of scrutiny to the United States’ clean‑energy tax credit regime. By designating Russia, Iran, North Korea and China as foreign entities of concern, the law forces any project seeking a credit to demonstrate that no more than 15% of its debt is held by these nations and that ownership structures do not grant effective control to foreign parties. Treasury’s preliminary guidance has addressed material assistance but left the core questions of debt exposure and control unanswered, creating a compliance vacuum that investors and developers must navigate.

This regulatory haze has immediate financial repercussions. Major banks such as Morgan Stanley and JPMorgan temporarily halted renewables financing, citing the risk of inadvertent violations. As a result, project sponsors are compelled to conduct deep‑dive investigations into the ultimate owners of private‑equity funds, lenders, and even secondary tax‑credit buyers. Lawyers now trace ownership through multiple tiers, often requiring disclosures of limited‑partner identities that were previously private. The added diligence has inflated legal fees, extended underwriting timelines, and forced some lenders to exit the tax‑equity market altogether, slowing the pipeline of projects slated for completion before the 2027 credit deadline.

Industry stakeholders are pressing for clearer guidance before the year’s end, hoping to limit the certification burden to the direct tax‑owner of each project. A streamlined definition would reduce the need for exhaustive investor vetting and restore confidence among financiers. Until then, the sector can expect a continued surge in legal work, with December‑style workloads becoming the new normal. The eventual Treasury clarification will be pivotal in determining whether the United States can meet its renewable‑energy ambitions without further cost overruns or project delays.
