Death of distributee

If the individual required to include amounts in gross income under such subparagraph dies before all of such amounts are included, all remaining amounts shall be included in gross income for the taxable year which includes the date of death.

If the spouse of the individual described in subclause (I) acquires the individual’s entire interest in any Roth IRA to which such qualified rollover contribution is properly allocable, the spouse may elect to treat the remaining amounts described in subclause (I) as includible in the spouse’s gross income in the taxable years of the spouse ending with or within the taxable years of such individual in which such amounts would otherwise have been includible. Any such election may not be made or changed after the due date for the spouse’s taxable year which includes the date of death.
