The Tax Court’s May 3, 2023, decision in ES NPA Holding, LLC v. Commissioner (T.C. Memo 2023‑55), upholding a taxpayer’s position to characterize a partnership interest as a profits interest under the “safe harbor” of IRS Revenue Procedure 93-27 (as clarified by IRS Revenue Procedure 2001-43), provides helpful guidance to issuers of profits interests, including private equity funds and other investment partnerships and their portfolio companies.
