IRS ruling program could reshape KPMG corporate tax deal advice

The IRS has opened a new lane for corporate tax certainty, and KPMG deal teams are likely to feel it first. Revenue Procedure 2026-21 lets taxpayers seek rulings on one or more significant issues that sit solely with the Associate Chief Counsel for Corporate, a shift that could change how corporate tax, M&A and restructuring advisers scope work, staff projects and manage client deadlines.

The practical effect inside KPMG is a tighter, more urgent workflow. When a client wants to spin off a business, combine entities or move assets in a way covered by sections 332, 351, 355, 368 or 1036, the ruling question may now be narrower and more surgical. That can help partners and senior advisers who need certainty to keep a transaction moving, especially in section 355 deals where one unresolved tax point can stall execution. It also means more pressure on the people doing the early issue spotting, because the request has to isolate a real legal question that is germane, specific and essentially free from doubt.

The IRS said the program is meant to use resources more efficiently and increase the availability and timeliness of letter rulings, after receiving numerous informal comments from taxpayers and practitioners about how long rulings take and how broad they have become. For KPMG professionals, that matters immediately. If clients start asking for narrower rulings earlier in the process, tax diligence, structuring memos and deal models will need to move faster, with less room for vague backup plans. A quicker ruling path can lower uncertainty for clients, but it also raises the bar for the advisers assembling the facts and drafting the ask.

The new procedure also gives the IRS flexibility to rule on part of an integrated transaction without blessing the whole deal. That is a meaningful change from the older posture. Rev. Proc. 2001-3 generally pushed the Service away from ruling on certain corporate reorganization provisions unless a significant issue had to be resolved, and even then it would rule on the entire transaction. Rev. Proc. 2009-25 later created a pilot for single-issue rulings in section 355 distributions, and Rev. Proc. 2013-32 tightened the scope again for sections 332, 351, 355, 1036 and section 368 reorganizations. KPMG said the new program responds to taxpayer and practitioner feedback and may improve the efficiency and timeliness of the letter-ruling process.

The result is a more targeted ruling regime, not a softening of standards. The IRS still will not issue comfort rulings in many cases, and a request has to present a genuine significant legal issue. For KPMG’s corporate tax, M&A and restructuring teams, that means the same deal work, but with more urgency, more precision and less tolerance for sloppy framing. The new program applies to requests postmarked or received after May 5, 2026, so the pressure to adapt is already here.
