I will be retiring at the end of the year under Ohio PERS. The option I want to retire under, plan c., allows the retiree to designate a beneficiary and the percentage of the retiree's amount to the beneficiary. I want to leave 50% but Ohio PERS tells me that under IRS code 401 a 9 I must leave 72%. I have tried reading the code but that leaves me bewildered. Can you explain this mandated percentage and why or direct me to a source? Thank you, Joe Szucs
