401k and Roth IRA

Your Roth IRA may considered a Roth 401K if it is a plan offered through your employer.  If this is the case,

 

(1) Yes, this is a Rollover from a 401K to a Roth 401K, through your employer plan.

 

(2) No, this is not a rollover to a Roth IRA.

 

On your 1099-R reporting this, you may have an amount in Box 5 designating the amount of your after-tax contributions contained in the Total Distribution amount in Box 1.

 

You will only be taxed on your pre-tax rollover amount (difference between Box 1 and Box 5), which may be shown in Box 2a.  The net effect on your taxes would be the same either way.

1. The code G Form 1099-R is indeed reporting the In-plan Roth Rollover.  Answer Yes.
2. This is not a rollover to a Roth IRA.  Answer No.
3. If you made after-tax contributions to the traditional account in the 401(k), answer Yes.  However, unless box 2b Taxable amount not determined is marked, the Form 1099-R should already have in box 2a the correct taxable amount and in box 5 the portion of the distribution that is nontaxable due to being attributable to your after-tax contributions.

Thank you for your reply. I understand it is "indeed reporting the in-plan roth rollover". However, I never made "direct ROTH contribution through 401k". I do roth in plan conversion for the entire amount of after tax contributions in 401k. Given that, what should be an answer to the following question - Is this 1099-R reporting a rollover of funds from a 401k plan to a "designated ROTH 401k plan"?

Yes, that's exactly right.  The Roth account to which the In-plan Roth Rollover is made is your designated Roth account in the 401(k) plan.  It is not a rollover to a Roth IRA.
