The following questions and answers relate to the distribution rules for IRAs provided in sections 408(a)(6) and 408(b)(3).
Yes, an IRA is subject to the required minimum distribution rules provided in section 401(a)(9). In order to satisfy section 401(a)(9) for purposes of determining required minimum distributions for calendar years beginning on or after January 1, 2003, the rules of §§1.401(a)(9)-1 through 1.401 and 1.401 for defined contribution plans must be applied, except as otherwise provided in this section. For example, whether the 5-year rule or the life expectancy rule applies to distributions after death occurring before the IRA owner's required beginning date is determined in accordance with §1.401(a)(9)-3 and the rules of §1.401(a)(9)-4 apply for purposes of determining an IRA owner's designated beneficiary. Similarly, the amount of the minimum distribution required for each calendar year from an individual account is determined in accordance with §1.401(a)(9)-5. For purposes of this section, the term IRA means an individual retirement account or annuity described in section 408(a) or (b). The IRA owner is the individual for whom an IRA is originally established by contributions for the benefit of that individual and that individual's beneficiaries.
The surviving spouse of an individual may elect, in the manner described in paragraph (b) of this A-5, to treat the spouse's entire interest as a beneficiary in an individual's IRA (or the remaining part of such interest if distribution thereof has commenced to the spouse) as the spouse's own IRA. This election is permitted to be made at any time after the individual's date of death. In order to make this election, the spouse must be the sole beneficiary of the IRA and have an unlimited right to withdraw amounts from the IRA. If a trust is named as beneficiary of the IRA, this requirement is not satisfied even if the spouse is the sole beneficiary of the trust. If the surviving spouse makes the election, the required minimum distribution for the calendar year of the election and each subsequent calendar year is determined under section 401(a)(9)(A) with the spouse as IRA owner and not section 401(a)(9)(B) with the surviving spouse as the deceased IRA owner's beneficiary. However, if the election is made in the calendar year containing the IRA owner's death, the spouse is not required to take a required minimum distribution as the IRA owner for that calendar year. Instead, the spouse is required to take a required minimum distribution for that year, determined with respect to the deceased IRA owner under the rules of A-4(a) of §1.401(a)(9)-5, to the extent such a distribution was not made to the IRA owner before death.
General rule. In the case of a trustee-to-trustee transfer from one IRA to another IRA that is not a distribution and rollover, the transfer is not treated as a distribution by the transferor IRA for purposes of section 401(a)(9). Accordingly, the minimum distribution requirement with respect to the transferor IRA must still be satisfied. Except as provided in paragraph (b) of this A-8 for recharacterizations, after the transfer the employee's account balance and the required minimum distribution under the transferee IRA are determined in the same manner as an account balance and required minimum distribution are determined under an IRA receiving a rollover contribution under A-7 of this section.
General rule. Except as provided in paragraph (b) of this A-11, all amounts distributed from an IRA are taken into account in determining whether section 401(a)(9) is satisfied, regardless of whether the amount is includible in income.
