Recently, I was asked if retirement accounts from multiple sources could be blended into one IRA account. The answer is yes. There is now a “however” added to that yes.
Starting in 2015, only one rollover from an IRA can be made to another IRA per 365 day period. If you have multiple IRA accounts that you wish to consolidate, it will now take longer. This rule does not apply to a Direct Rollover form an employer plan to an IRA, or Trustee to Trustees transfers. You could process a Direct Rollover and an IRA transfer in the same 365 day period.
