Back to the Future: IRS and Treasury Reinstate Pre‑2024 Guidelines for Spin‑Off Private Letter Rulings

On October 28, 2025, Cravath prepared a memo for its clients entitled “Back to the Future: IRS and Treasury Reinstate pre‑2024 Guidelines for Spin‑Off Private Letter Rulings.” The memo examines the Internal Revenue Service’s recently released Rev. Proc. 2025‑30, which provides updated guidelines for taxpayers requesting private letter rulings from the IRS for tax‑free spin‑off and split‑off transactions under Section 355. Rev. Proc. 2025‑30 supersedes Rev. Proc. 2024‑24 and withdraws Notice 2024‑38 (together the “2024 Guidance”).
