While Gadgetfreak is right to mention the 5%-owner variation, consider further that whether a participant is or was “a 5-percent owner (as defined in section 416)” for § 401(a)(9) is determined “with respect to the plan year ending in the calendar year in which the employee attains the applicable age[.]” Internal Revenue Code of 1986 (26 U.S.C.) § 401(a)(9)(C)(ii)(I). “For purposes of section 401(a)(9), a 5-percent owner is [a participant] who is a 5-percent owner (as defined in section 416) with respect to the plan year ending in the calendar year in which the [participant] attains the applicable age.” 26 C.F.R. § 1.401(a)(9)-2(b)(3)(ii) https://www.ecfr.gov/current/title-26/part-1/section-1.401(a)(9)-2#p-1.401(a)(9)-2(b)(3)(ii).
Nancy’s query supposes that the lawyer “changed status . . . in 2021 when he attained age 70.” Many law firms’ partnership agreements provide age 70 as a mandatory or presumptive retirement age. Often, a retired partner continues working, but on a less active schedule. A change in classification from an active partner to an inactive or retired partner often involves adjusting or redeeming a partner’s capital interests, profits interests, or both.
By 2024 or the other relevant year in which the participant reached age 73, he might no longer have been a 5% owner.
For a participant not constrained by the 5%-owner variation, one’s required beginning date might follow from the later of one’s applicable age and “[t]he calendar year in which the [participant] retires from employment with the employer maintaining the plan.” 26 C.F.R. § 1.401(a)(9)-2(b)(1)(ii) https://www.ecfr.gov/current/title-26/part-1/section-1.401(a)(9)-2#p-1.401(a)(9)-2(b)(1)(ii).
Again, a service provider might suggest that the plan’s administrator check carefully the facts and consider prudently how relevant law applies regarding the facts found.
