Beginning January 1, 2015, the IRS will restrict investors to one indirect IRA rollover in any 12-month period. Prior to this, one IRA rollover per IRA account was allowed. This does not apply to trustee transfers nor direct rollovers from employer plans such as 401ks. There is no limit with these transactions. Indirect rollovers are when the investor receives a check made payable to them and has 60 days to deposit into an IRA. Therefore, when possible, it is best to do trustee to trustee transfers whereby the IRA custodian sends the funds on your behalf.
