Before January 1, 2015, an individual could rollover a distribution from one IRA to another IRA in a nontaxable transaction if the rollover was completed within 60 days after the income was received. This could be done only once in any 1-year period. However, it was determined on an IRA-by-IRA basis. Starting January 1, 2015, the nontaxable distribution on rollover rule will be applied on an aggregate basis. So, no matter how many IRA accounts a person has, only one nontaxable rollover per year will be allowed.
