Tax efficiency/mega-backdoor question
« on: June 03, 2017, 09:25:50 PM »
Hi,

I have a traditional IRA (rolled over from prior firm's 401k plans) of $120k and am contributing $18k to my current employer's plan. My income is about $190k. My wife makes about $60k and also contributes the max to her 401k plan.

My understanding has been that our combined income is too high to contribute to Roth IRA accounts directly. However, I read about the Mega-backdoor option which assumes that my employer's 401k plan allows in-service withdrawals and after-tax contributions. I will check with HR next week if that is possible.

I'm now getting a little confused with what would happen to my traditional IRA account when I initiate the Mega-backdoor rollover (assuming that option is available to me). Would the pre-tax 401k contributions end up in my traditional IRA account and while the after-tax contributions are converted into a separate Roth IRA? Are there any additional conditions attached, e.g. that I would need to convert my traditional IRA to a Roth as well? (or did I get it confused this with something else)

Thank you -- aside from the IRA and our 401ks we just have a taxable investment account that we fund with our monthly savings. I would love to learn if there are any obvious ways we could be more tax efficient with our retirement accounts and taxable accounts going forward.

For the backdoor Roth, there are tax implications if you already have money in a traditional IRA.

For the mega backdoor Roth, there are no implications. You rollover the after-tax, non-Roth contributions directly from your 401(k) into the Roth IRA.

 

Wow, a phone plan for fifteen bucks!
