The IRS launches a new ruling program allowing taxpayers to obtain guidance on specific major legal issues in corporate transactions without requiring comprehensive rulings on all tax consequences, applicable to requests submitted after 5 May 2026.
The US Internal Revenue Service (IRS) has issued Revenue Procedure 2026-21, introducing a significant issue ruling program that allows taxpayers to request rulings on specific major legal issues under the jurisdiction of the Associate Chief Counsel (Corporate).
The program enables the IRS to rule on individual significant issues within a broader transaction without addressing all related tax consequences and applies to covered ruling requests submitted after 5 May 2026.
Under the significant issue ruling program described in this revenue procedure, taxpayers may request, and the Service may issue, a ruling on part of an integrated transaction described in § 332, 351, 355, 368, or 1036.
In addition, taxpayers may request, and the Service may issue, a ruling on a particular legal issue under a section of the Code or the Income Tax Regulations with respect to a transaction (or part thereof) rather than a ruling that addresses all aspects of that section (or any other section) with respect to the transaction (or part thereof). For example, the Service may issue a letter ruling addressing significant issues presented by the application of § 355(e), 1.368-1(d), or 1.368-2(k), even though the ruling does not address the overall qualification of the transaction under § 355 or 368.
In addition, the Service may rule on the tax consequences (such as nonrecognition and basis) resulting from integrated transactions described in § 332, 351, 355, 368, or 1036 to the extent that a significant issue is presented under related Code sections that address such tax consequences. For example, a § 351 exchange that does not present any significant issues under § 351 may present a significant issue regarding the application of § 358 to the transferor in the exchange. This revenue procedure does not limit the number of significant issues with respect to a transaction that may be the subject of a single letter ruling.
However, the Service reserves the right to rule on any other issue related to the transaction (including ruling adversely) if the Service believes that doing so would be in the interest of sound tax administration. If the Service issues a letter ruling on a significant issue under Rev. Proc. 2026-1 as modified and amplified by this revenue procedure, the letter ruling will state that no opinion is expressed as to the overall tax consequences of the transactions described in the letter ruling or as to any issue or step not specifically addressed by the letter ruling.
A significant issue is a germane and specific issue of law, provided that a ruling on the issue would not be a comfort ruling or the conclusion in such a ruling otherwise would not be essentially free from doubt. An issue is germane if the resolution of the issue is necessary to determine an element of the tax treatment of the transaction. An issue is specific if it is the narrowest articulation of the germane issue. A change of circumstances arising after a transaction ordinarily does not present a significant issue with respect to the transaction.
