As I was properly corrected above, if a participant dies before their Required Beginning Date (RBD), the participant does not have to take an RMD for the year in which the participant died, regardless of the age of the participant.
This person's RBD is 4/1/15, and he died before 4/1/15. No RMD for 2014.
RMD's to the beneficiaries begin in the year after the participant died (2015), generally based on life expectancy rule or the 5-year rule (check the terms of the plan). The beneficiary's RMD for 2015 is paid before the rollover to the inherited IRA.
