(a)
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.
