I have a 401K at a former employer that contains a substantial amount of after-tax contributions.
I have received some input that I can roll this over in two parts to, in effect, put the pre-tax money (contributions + all earnings) into a TIRA and the after-tax contributions in to a ROTH IRA. The advice I was given said that to do this, it would be necessary to do the rollover in two parts and the sequence was important.
First, do a partial rollover of an amount equal to the pre-tax funds to a TIRA.
Second, roll the remainder to a ROTH IRA.
According to one IRS publication (and input from one source), if a partial rollover is done, the IRS deems the money to come from pre-tax sources first. Thus, the first partial rollover deems the remainder of the funds as after-tax funds. These are then subsequently rolled to the ROTH in a separate rollover transaction.
I am interested in any opinions as to whether the above is a valid way to direct only the after-tax part to a ROTH and leave the pre-tax part in a TIRA (and continue to defer taxes).
Thanks
