1099R and in-service conversion of after-tax contributions in 401k
I have a question about the tax consequence of in-service rollover of after-tax contributions and the associated pre-tax earnings from my 401k sub-account to my personal Vanguard Roth IRA account. I contributed after tax dollars to my retirement account in 2017. At the end of 2017 I requested the after-tax contributions ($9852) and the associated pre-tax earnings ($407) to be rolled over to my Vanguard Roth IRA account. As expected I received a single check payable to my Roth account administrator (Vanguard) and I promptly deposited the check into my Vanguard Roth IRA account. This month I received my 1099R from my 401k custodian and it doesn’t seem to have any amount as taxable income. Here is the relevant information:
Box 1 (Gross Distribution): $10,259
Box 2a (Taxable amount): $0
Box 2b (Taxable amount not determined): Not checked
Box 2b (Total distribution): Not checked
Box 3 (Capital gain): $0
Box 4 (Federal income tax withheld): $0
Box 5 (Employee contributions): $9852
Box 7 (Distribution code): G
Box 7 (IRA/SEP/SIMPLE): Not checked
Shouldn’t 1099R be showing $407 (pre-tax earnings from my after-tax contributions) as taxable, or maybe have Box 2b Taxable amount not determined checked?
Thanks.

You are corrrect. Box 2a should show 407. This has been a fairly frequent 1099R error for plans, since they process the vast majority of direct rollovers to traditional IRAs where 2a is always 0. Force of habit. You should request a corrected 1099R, and the error is obvious enough that there should not be any resistance. The entry in Box 5 indicates that the issuer at one point did recognize that the distribution was headed to a Roth, otherwise 5 would be empty.
