mechanics of tIRA -> 401k

Post by crit » Thu Oct 12, 2017 6:24 pm

My spouse has a tIRA at vanguard that is 90% rollover and 10% deductible contribution. His company just switched to Fidelity as 401k provider, and they will accept a rolled-in contribution (thus opening the backdoor Roth for him). I have two questions about the mechanics:

1. How does the tax reporting work? My understanding is that we will get vanguard to issue a distribution check without withholding taxes, payable to Fidelity FBO Spouse, and we send that to Fidelity along with their rollover contribution forms. I expect we will get a 1099R from vanguard, and it should have code G as a rollover, but will we also expect some kind of confirmation tax reporting from Fidelity?

2. It appears (not having done it yet) that Vanguard just issues a distribution check for the entire contents, without separating the deductible and the rollover components ... is that correct?

Thanks in advance, I owe a ton to this forum!
And I have done the backdoor Roth for myself already, so I'm fine there.

It is not permitted to rollover anything other than taxable assets from an IRA to a 401k. You must specifically determine your pre-tax balances and after-tax contributions. You only rollover the pre-tax balance to the 401k. That leaves just the after-tax contribution in the IRA. You can then do a Roth conversion of that balance tax-free to a Roth IRA.

The whole balance is pre-tax: the contribution was deducted from taxes that year, making it pre-tax. The rollover is also pre-tax.

I misunderstood. I was confused, because there is never any reason to separate pre-tax rollover amounts and pre-tax contributions when doing a rollover. The only reason for separating is if you have pre-tax and non-deductible contributions.

bump -- can anyone answer question #1, about tax reporting of tIRA to 401k rollovers?

You are correct about the 1099R. However, while IRA custodians must report regular and rollover contributions they receive on Form 5498 to both taxpayer and IRS, there is no equivalent reporting for rollovers received by qualified plans. Despite the direct rollover G coding, this leaves the IRS uneasy that the funds were actually rolled over. Therefore, the 1040 filing instructions indicate that the taxpayer is to include an explanatory statement with their return about the amount and date of the rollover.

2. It appears (not having done it yet) that Vanguard just issues a distribution check for the entire contents, without separating the deductible and the rollover components ... is that correct?

Yes, that is correct because that breakdown has no significance. Note that if he later leaves that employer and rolls his 401k over to an IRA again, the entire IRA balance from that rollover is considered an IRA rollover contribution, even though some of it was once contributed as a regular IRA contribution. If that rollover was done to a rollover IRA it might have long range significance because if his next employer were to only accept IRA rollovers from rollover IRAs, he could then roll that entire rollover IRA back to the new 401k.
