After writing a walkthrough for how to enter mega backdoor Roth in TurboTax and how to enter mega backdoor Roth in FreeTaxUSA, a reader asked me to do one for H&R Block software as well.
A mega backdoor Roth is different from a regular backdoor Roth. It’s done by making non-Roth after-tax contributions to a 401k-type plan and then moving it to the Roth account within the 401k-type plan or taking the money out (with earnings) to a Roth IRA. It’s a great way to put additional money into a Roth account without having to pay much additional tax. Not all plans allow non-Roth after-tax contributions but some estimated that 40% of people can do it.
H&R Block is in general less expensive than TurboTax. It has a downloaded version and an online version. The downloaded version is both less expensive and more powerful. The downloaded Deluxe + State edition (or the Deluxe Federal-Only edition when you live in a state without an income tax) can handle pretty much everything. It often goes on sale for $20-25 on Amazon, Walmart, or Newegg, sometimes for under $20. Federal e-filing is included. State e-filing costs extra but you can simply print and mail or use the printed forms to file on your state government’s website.
Suppose you did a mega backdoor Roth last year. You’ll receive a 1099-R form from your 401k plan in January. You’ll need to account for it on your tax return. Here’s how to do it in H&R Block downloaded software.
In-Plan Rollover
You can do the mega backdoor Roth in two ways — rollover within the plan or withdraw to a Roth IRA. Rolling over within the plan is much easier, and many plans automate the process. Withdrawing to a Roth IRA also works. See the previous post Mega Backdoor Roth: Convert Within Plan or Out to Roth IRA?
Let’s first look at rolling over to the Roth account within the plan. Here’s the scenario we’ll use as an example:
You contributed $10,000 as non-Roth after-tax contributions to your 401(k). By the time the money was rolled over to the Roth account within the plan, your contributions earned $200. You rolled over $10,200 to your Roth 401(k) account.
I’m using 401(k) as a shorthand. It works the same in a 403(b). Now the entries into H&R Block software.
Go to Federal -> Income -> IRA and Pension Income (Form 1099-R).
Our 1099-R is a normal 1099-R. Enter the numbers from your 1099-R as-is. Ours looks like this:
The gross amount transferred to the Roth 401k account shows up in Box 1. The earnings are in Box 2a. If you didn’t have earnings in your rollover, Box 2a is zero. “Taxable Amount Not Determined” under Box 2b is left unchecked. The amount of your non-Roth after-tax contributions shows in Box 5. Box 7 has code G.
The IRA/SEP/SIMPLE box in Box 7 on our 1099-R is unchecked.
We’re not a retired public safety officer.
We moved the money within the plan. The Roth 401k account is called a “designated Roth account” in the plan.
That’s it. It’s as simple as that. Now we verify we’re taxed only on the $200 in earnings, and not on the $10,000 non-Roth after-tax contributions.
Click on “Forms” in the top menu bar. Double-click on “Form 1040 and Schedules 1-3” in the forms list. Scroll down to find Line 5. The gross amount transferred to the Roth 401k account shows on Line 5a. Line 5b shows you’re taxed only on the earnings. If you didn’t have earnings, Line 5b will be zero.
Rollover to Roth IRA
It’s just as easy to report the mega backdoor Roth if you took the money out of the 401k plan and sent it to a Roth IRA. We’ll use the same example as above except you did the rollover to a Roth IRA instead of to the Roth 401k account within the plan.
Enter your 1099-R as-is in the same way as above.
The IRA/SEP/SIMPLE box is still unchecked.
We’re still not a retired public safety officer.
The only difference is we rolled over to a Roth IRA this time.
Now we verify we’re taxed only on the $200 in earnings, and not on the $10,000 non-Roth after-tax contributions.
Click on “Forms” in the top menu bar. Double-click on “Form 1040 and Schedules 1-3” in the forms list. Scroll down to find Line 5. The gross amount transferred to the Roth 401k account shows on Line 5a. Line 5b shows you’re taxed only on the earnings. If you didn’t have earnings, Line 5b will be zero.

Awesome! Thanks for posting so quickly after my question.

Do you only get the “Which plan did you roll over your distribution into” prompt if you have a taxable amount? I have 2 1099-Rs which nothing taxable and never got that prompt to appear.
Thanks!

As you see here, choosing Roth 401k or Roth IRA didn’t affect Form 1040 Line 5 anyway. It doesn’t matter you didn’t get that choice as long as your Form 1040 Line 5 is correct.
