Do the 2025 IRS life expectancy tables change distribution rules for inherited IRAs and beneficiaries?

Executive summary
The 2025 IRS life‑expectancy tables update the numerical factors used to compute required minimum distributions (RMDs) but do not, by themselves, change the statutory distribution regimes for inherited IRAs — those rules (the SECURE Act 10‑year rule, spouse rollover options, special eligible‑designated‑beneficiary rules, and when annual RMDs apply) remain in Treasury/IRS guidance and Publication 590‑B; the tables simply feed into the arithmetic beneficiaries must follow when annual RMDs are required (IRS Pub. 590‑B; [1], p1_s2). Finalized IRS guidance that takes effect in 2025 does require some beneficiaries to resume or begin annual RMDs in certain 10‑year cases, but that requirement is a regulatory change about timing and applicability, not a change to the role life‑expectancy tables play in calculations (Fidelity summary; [2]4).
1. What the tables actually do: arithmetic inputs, not new rules
Life‑expectancy tables in Appendix B of Publication 590‑B provide denominators (the “life‑expectancy factors”) used to calculate annual RMD amounts when an annual distribution obligation exists; taxpayers divide the prior‑year account balance by the applicable table factor to compute the RMD for that year — a mechanical calculation explained in IRS Publication 590‑B [1] [2]. The Single Life, Uniform Lifetime, and Joint Life tables are tools for computing amounts; changing the numbers in those tables alters annual RMD dollar amounts but does not rewrite who must take distributions or the statutory 5‑/10‑year timing frameworks Congress and Treasury set [3] [4].
2. What changed for 2025 in practice: updated factors and regulatory timing that matters
Beginning in 2025 the IRS applies updated table factors that will affect the size of annual RMDs (financial‑planning sites compare the tables year‑to‑year and show changed denominators and percentage RMD rates) — beneficiaries will see slightly higher or lower required withdrawals depending on the new factors and their ages (ImpactAdvisor; p1_s3). Separately, finalized IRS guidance implemented to take effect in 2025 requires certain non‑spouse beneficiaries who inherited accounts subject to the SECURE Act’s 10‑year rule to take annual RMDs in years 1–9 if the original owner had already begun RMDs, meaning life‑expectancy tables will be used again in 2025 to compute those annual amounts where applicable (Fidelity; [2]4).
3. Who is affected and how to read the interaction between tables and rules
If a beneficiary falls into a scenario that requires annual life‑expectancy distributions — for example a non‑spouse who inherited from an owner who had already started RMDs, or a spouse electing life‑expectancy payments — the beneficiary uses the Single Life or Joint Life table appropriate to their status to compute the year’s RMD and typically reduces the denominator by one each subsequent year (Pub. 590‑B examples; [1], p1_s2). By contrast, beneficiaries subject solely to a pure 5‑ or 10‑year payout (where no annual RMDs are required by the underlying rule) do not use the tables for annual calculations; the table updates don’t change the end‑date requirement that the account be emptied within the statutory period (Greenleaf Trust; [2]1).
4. How advisors and intermediaries are framing it — and where narratives exaggerate
Advisory coverage stresses two separate messages: that the numeric table updates will tweak annual RMD sizes, and that 2025 is consequential because regulatory guidance restores annual RMD obligations in some SECURE‑Act 10‑year cases (ImpactAdvisor, Morningstar, Snowbirds Wealth Management summaries; [7], [8], p1_s9). Some commentary conflates the two and implies the tables “change the rules”; that framing privileges headlineable novelty over technical clarity — the tables change calculations, the regulations change when distributions must be taken in certain inherited‑IRA scenarios [5] [4]. Readers should note that vendor and advisor pieces can have an implicit agenda to prompt engagement or selling advisory services, while IRS documents are policy‑authoritative [6] [1].
5. Bottom line and practical steps
The 2025 tables do not rewrite distribution rules for beneficiaries: they modify the calculation inputs for annual RMDs where annual RMDs are required, and Treasury/IRS regulatory changes that take effect in 2025 do expand the years in which some beneficiaries must take annual RMDs — meaning more beneficiaries will apply those updated table factors in 2025 and later (IRS Pub. 590‑B; Fidelity summary; [1], [2]4). Because the interaction is technical, beneficiaries should identify which statutory regime they fall under (spouse rollover, eligible designated beneficiary, 5‑year/10‑year rule, or annual life‑expectancy RMDs) and then apply the appropriate 2025 table factor or consult a trusted tax advisor to avoid missed‑RMD penalties (Vanguard and Greenleaf Trust guidance; [9], [2]1).
