Roth IRA to Roth 401(k)

[Guest Clain]

Is a rollover from a Roth IRA into a Roth 401(k) allowed? And if so, when does the 5 year window begin? Is it the starting date for the Roth IRA or the starting date of the Roth 401(k)?

No, it's not allowed...I think difficult questions like this might be part of the reason.
