IRA Rollover into 401(k) Plan

[Alex Daisy]

A Participant wants to rollover his IRA to his 401K.

Is this allowed?

I know you can rollover over from a 401k into an IRA, but I was not sure about the opposite way.

[WDIK]

You can if the plan allows it.

…and if the IRA includes after-tax amounts, don’t forget that those amounts must be left in the IRA as they cannot be rolled to the 401(k) plan.

[Guest TooMuchFreeTime]

Wouldn't after-tax IRA amounts be permitted for plans with a after-tax feature?

Also, remember that the MRD rules of 401(a)(9) continue to apply and may restrict the ability to rollover an IRA into a qualified plan.
