Joint Life Table* Case Study

This example shows how RMDs can be lower when spouse is the sole beneficiary for the entire distribution year.
Joint Life Table RMDs apply where the spouse is exactly 20 years younger.

More examples 👆

* First RMD distributions get a grace period: withdrawal may be delayed until April 1, 2026 in this example. NOTE: delaying means two RMDs must be taken in 2026 (one for 2025 and one for 2026). For age 73, the Uniform Lifetime Table factor is 26.5 (3.77%). This is the official first-year RMD percentage under current law (SECURE 2.0).

Sources: IRS Pub. 590-BTreasury Reg. §1.401(a)(9)-5, Q&A-4 — designated beneficiary must be sole for the entire distribution year (for lifetime RMDs).

Inherited IRAs can have RMDs. If so, there can be tricky rules to determine the "Age".
Those rules (what row applies for you here) are here: IRS: Inherited IRAs

part of a qualifying series of substantially equal periodic payments (SoSEPP)
