Whose Life Expectancy is used, when a second-generation (successor) beneficiary inherits an IRA?

Last Updated August 21, 2018


Dear Denise,


An individual inherited an IRA from her father, and had been taking distributions over her single life expectancy. She named her son as the beneficiary of her inherited IRA. She (the original beneficiary) subsequently died, and  her son now has to take distributions from the IRA which he has inherited. Should he take distributions over his life expectancy or over his mother’s life expectancy?

Also, how should the son’s inherited IRA be titled/registered? That is, whose name should  be included , the original owner's or his mother's?

The grandchild (son) should take distributions over his mother’s life expectancy. The mother’s life expectancy is determined in the year after the grandfather died, and 1(one) is subtracted for each year that has passed. 

A second generation beneficiary’s (or successor beneficiary’s) life expectancy is never used to determine distributions from an inherited retirement account.  
Based on the guidance provided in the instructions for filing IRS Form 1099-R and Form 5498, and IRS Notice 2007-7, the account should be titled "Grandchild beneficiary of Mother (deceased) IRA”, or any other variation, providing it shows the grandchild as the beneficiary, and his mother as the decedent.
IRS Notice 2007-7 A-13 states that “ The IRA must be established in a manner which identifies it as an IRA with respect to a deceased individual and also identifies the deceased individual and the beneficiary, for example, “Tom Smith as beneficiary of John Smith.” Therefore, since the grandchild is the beneficiary of the mother, the registration should show the mother’s name and the child’s name.
