(i) General rule. If the annuity contract (or, in the case of annuity distributions from a defined benefit plan, the distribution option) under which distributions to the payee are being made is an impermissible annuity distribution option, then the required minimum distribution for each calendar year for purposes of
section 4974 is the amount that would be distributed under the applicable permissible annuity distribution option described in this paragraph (d)(3) (or the amount determined by the Commissioner if there is no option of this type). The determination of which permissible annuity distribution applies depends on whether distributions commenced before the death of the employee, whether the plan is a defined benefit or defined contribution plan, whether there is a designated beneficiary for purposes of
section 401(a)(9), and whether the designated beneficiary is an eligible designated beneficiary under
section 401(a)(9)(E)(ii). For this purpose, the determination of whether there is a designated beneficiary and whether that designated beneficiary is an eligible designated beneficiary is made in accordance with
§ 1.401(a)(9)-4, and the determination of which designated beneficiary's life is to be used in the case of multiple designated beneficiaries in made in accordance with
§ 1.401(a)(9)-5(f).
