Which SECURE 2.0 provisions affecting RMDs were delayed to 2026 and what practical changes will apply when they take effect?
Executive summary
The IRS pushed back the applicability date for portions of its 2024 proposed regulations interpreting SECURE 2.0 so those specific RMD-related rules will not apply until the 2026 distribution calendar year (generally effective Jan. 1, 2026) [1] [2]. The delay responds to industry concerns about implementation timing and affects a set of technical clarifications—most notably rules about surviving-spouse treatment and the interaction of Roth-designated accounts with RMDs—while leaving other changes (like the 10‑year rule and certain annuity valuation proposals) on a different timeline [3] [4] [5].
1. Which SECURE 2.0 RMD provisions were explicitly delayed until 2026
The IRS Announcement extended the anticipated applicability date for many of the proposed regulations that interpret SECURE 2.0, stating those future final regulations generally will apply beginning in the 2026 distribution calendar year [1] [2]. Among the specific items cited by multiple industry summaries as falling into that delayed bucket are the rule treating a surviving spouse who is the sole beneficiary as being able to elect to be treated as the participant for RMD purposes (the “surviving‑spouse treated as participant” election) and clarifications about Roth-designated accounts in employer plans, including that Roth balances in employer plans are not subject to lifetime RMDs and that distributions from Roth accounts do not count toward satisfying a participant’s RMD for the year [5] [6] [2] [7].
2. What the delay did not cover — items still on earlier timetables
The IRS did not push every RMD rule into 2026: the final regulations addressing the SECURE 1.0 changes and certain SECURE 2.0 items (notably the 10‑year rule that governs many beneficiary distributions) retain effective dates tied to the earlier regulatory schedule and related plan-amendment timelines, and the annuity‑valuation proposed rule for partial annuitization was not extended in the same announcement and remains separately proposed with its own timetable [4] [3] [5]. Industry guidance further makes clear that plan amendment deadlines for many SECURE 1.0 and SECURE 2.0 conforming changes remain on the calendar through 2026 under the IRS required‑amendments list [8].
3. Practical changes that will apply when delayed provisions take effect in 2026
When the delayed rules take effect, surviving spouses who are sole beneficiaries will have a statutorily clarified path to elect to be treated as the participant for RMD purposes—potentially letting those spouses delay distributions as if they were the original account owner—which alters both timing and tax planning for many inherited accounts [5] [3]. Roth accounts in employer plans will be formally aligned more closely with Roth IRAs for lifetime RMD treatment so plan Roths ordinarily won’t require lifetime RMDs, and the clarification that Roth distributions cannot be used to satisfy RMDs will force recordkeepers and participants to segregate pre‑tax and Roth withdrawals for RMD calculation and compliance purposes [2] [6] [7]. Those shifts affect year‑end distribution logistics, tax-withholding choices, and estate/beneficiary modeling that advisors and administrators must implement by the 2026 distribution year [9] [7].
4. What participants, sponsors and recordkeepers must do between now and 2026
The IRS told taxpayers to follow a reasonable, good‑faith interpretation of the statutory provisions until the final regulations apply, acknowledging implementation pain points raised by commenters and giving the industry breathing room to update systems and plan documents [1] [10] [3]. Plan sponsors, recordkeepers and advisors should inventory accounts with mixed pre‑tax and Roth balances, review beneficiary designations with surviving‑spouse scenarios in mind, and track plan‑amendment deadlines called out on IRS guidance and the required‑amendments list [8] [10]. Legal and recordkeeping vendors sought the delay explicitly because automated calculation, reporting systems, and plan language changes would be difficult to retrofit by the original effective date [2] [3].
5. Competing viewpoints, limits of current reporting, and why it matters
Industry groups framed the delay as necessary and practical to avoid operational errors, while some consumer‑facing outlets emphasized the tax‑planning opportunities the postponed rules preserve for retirees; both perspectives are supported in the notices and commentary [2] [7]. Reporting and agency announcements identify which proposed provisions are delayed and which are not, but available sources do not provide the full text of every final regulation expected in 2026 nor a definitive list of every micro‑technical change that will follow, so advisers and taxpayers must monitor the IRS final regulations and Announcement 2025‑2 and plan for the 2026 distribution calendar year [1] [5].
