I think you both said it all…..
In general, if a trust is the beneficiary, then the account is treated as not having a designated beneficiary, unless the trust is ‘qualified’. For this purpose, qualified means meeting certain requirements that allows one to ‘look through’ the trust, and use the life expectancy of the oldest beneficiary of the trust for RMD – including post death RMD- purposes( see bottom of page 47 of the Final RMD Regulations at
http://www.irs.gov/pub/irs-regs/td8987.pdf for a definition and page 36 of the 2005 version of IRS Publication 590 at
http://www.irs.gov/pub/irs-pdf/p590.pdf).
For a non-qualified trust the RMD is calculated using the uniform table (i.e. assuming the beneficiary is ten years younger than the participant) during the participant’s lifetime.
If the trust is qualified, then the life expectancy of the oldest identifiable beneficiary under the trust can be used for RMD purposes-including post death RMDs. This means that while the participant is alive, the RMD is calculated using the uniform table. An exception applies if the spouse of the participant is the sole beneficiary of the trust, and she is more than 10 years younger than the participant. In such a case, the RMD can be calculated using the joint life table.
This may seem pretty straightforward. But the complex nature of a trust makes it challenging to determine whether the trust meets the requirements that would allow the use of the life expectancy of a beneficiary under the trust. For instance---assume the trust has two individuals and one charity as beneficiaries (of the trust), that could result in the life expectancy of the beneficiaries not being eligible for purposes of calculating the RMD. However, exceptions may apply if the trust includes certain provisions . Which is why I agree that it pays to get someone who is an expert in the area of trust to assist with making the correct determination.
I agree that Natalie’s book -available at
