Why It Matters

Your clients depend on compliance documentation you can stand behind.

Each clean energy tax credit transaction depends on documented compliance across FEOC restrictions, PWA requirements, Domestic Content thresholds, BOC deadlines, and Section 48E obligations. A gap in any one of them creates recapture risk that may fall on your client. Accounting firms, law firms, and marketplaces are increasingly expected to vet compliance documentation as part of transaction due diligence, and the consequences of missing a gap after close are severe.

Empact delivers third-party certifications, reliance letters, and audit-ready documentation structured to satisfy the standards of leading financial and legal advisors. Our work is validated through Agreed Upon Procedures (AUP) from Big 4 firms.

What You Get

Key deliverables that integrate into your client engagements.
