One might consider these steps to follow Luke Bailey’s line of inquiry.
“For purposes of section 401(a)(9), a 5-percent owner is an employee who is a 5-percent owner (as defined in section 416)[.]” 26 C.F.R. § 1.401(a)(9)-2/Q&A-2(c).
That section defines: “For purposes of this paragraph, the term ‘5-percent owner’ means— (I) if the employer is a corporation, any person who owns (or is considered as owning within the meaning of section 318) more than 5 percent of the outstanding stock of the corporation or stock possessing more than 5 percent of the total combined voting power of all stock of the corporation[.]” Internal Revenue Code of 1986 (26 U.S.C.) § 416(i)(1)(B)(i)(I).
That section provides: “Stock owned, directly or indirectly, by or for a trust (other than an employees’ trust described in section 401(a) which is exempt from tax under section 501(a)) shall be considered as owned by its beneficiaries in proportion to the actuarial interest of such beneficiaries in such trust.” I.R.C. § 318(a)(2)(B)(i) (emphasis added).
Accord 26 C.F.R.§ 1.416-1/Q&A-17, Q&A-18.
For thoroughness, one might check whether the proposed rules to interpret and implement Internal Revenue Code § 401(a)(9) answer the question similarly or differently.
