How does Rev. Proc. 2025-30 affect §355 PLR timing?

In late September 2025, the IRS released Revenue Procedure 2025-30, restoring important procedures for requesting private letter rulings (PLRs) for §355 transactions. While the update may appear procedural, it has meaningful implications for planning timelines and documentation expectations.  

Tax professionals advising on corporate separations and reorganizations should understand how these changes affect both strategy and timing.

A return to familiar guidance

Rev. Proc. 2025-30 applies to ruling requests submitted after Sept. 29, 2025. It largely reverses the stricter approach introduced in Rev. Proc. 2024-24 and reinstates earlier guidance from Rev. Proc. 2017-52 and Rev. Proc. 2018-53.

This shift signals a return to a more familiar framework for requesting rulings. The IRS also revoked Notice 2024-38 and withdrew proposed regulations that would have added complexity and reporting requirements. For taxpayers and practitioners, this means fewer procedural hurdles and more reliance on established practices.

Key changes to §355 PLR requests

Rev. Proc. 2025-30 affects private letter ruling requests for certain §355 transactions in several ways.

Reduced documentation burden

The prior guidance required detailed representations and comprehensive legal analysis. The new procedure removes many of those heightened requirements by restoring earlier standards. Submissions may require less documentation than under Rev. Proc. 2024-24; however, accuracy and completeness remain essential.

Reinstated representations and analysis

The procedure restores representations related to control, liabilities, controlled securities, other property, solvency and certain debt transactions. It also restores the analytical framework for issues such as Distributing Debt, which is central to many §355 divisive reorganizations.

Greater flexibility in structuring

By stepping away from the stricter rules and abandoning proposed regulations, the IRS allows more flexibility in structuring spin-offs and similar transactions. This is especially important for transactions involving complex debt arrangements.

How planning timelines are affected

Although the updated procedure restores a more familiar framework for certain aspects of the ruling process, it does not eliminate timing challenges. In some cases, it creates new considerations.

More familiar preparation, but not faster rulings

With fewer documentation requirements, taxpayers may be able to assemble and submit PLR requests more quickly. However, the IRS review process has not changed. Practitioners should not expect faster response times from the IRS.

Transition timing matters

The new rules apply only to submissions made after Sept. 29, 2025. Taxpayers with pending or planned requests must decide whether to move forward under the previous guidance or adjust timing to take advantage of the updated procedure.

This decision can affect both workload and strategy.

Earlier planning becomes more important

The return to a principles-based framework means taxpayers must rely more on existing law and professional judgment rather than detailed procedural rules. As a result, advisors should engage earlier in the transaction process to identify potential issues, evaluate structures and determine whether a ruling is necessary.

Practitioners should also account for Rev. Proc. 2026-3, the current annual procedure identifying areas in which the IRS will not issue rulings or will not ordinarily issue rulings. It does not replace Rev. Proc. 2025-30, but it identifies issues on which the IRS will not issue rulings or will not ordinarily issue rulings, including certain §355 issues. Before preparing a §355 PLR request, practitioners should determine whether the issue is one the IRS will consider.

Practical considerations for practitioners

These steps can help reduce delays and improve the quality of §355 PLR submissions.

• Review and update standard PLR request templates. 
• Engage earlier in transaction planning discussions. 
• Evaluate timing strategies for upcoming or pending requests. 
• Confirm whether the IRS will rule on the issue under Rev. Proc. 2026-3.
• Be prepared to rely more on technical analysis and judgment. 

Rev. Proc. 2025-30 restores a more flexible and familiar approach to private letter ruling requests for certain §355 transactions. While it reduces procedural burdens, it also places greater responsibility on taxpayers and advisors to support their positions. Planning timelines may benefit from faster preparation, but thoughtful analysis and early engagement are more important than ever.
