A mega backdoor Roth means making non-Roth after-tax contributions to a 401k-type plan and then moving it to the Roth account within the 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.
Suppose your plan allows it and you executed a mega backdoor Roth. You will receive a 1099-R from the plan in the following year. You will need to account for it on your tax return. It’s quite straightforward. Here’s how to do it in TurboTax Deluxe downloaded software. The downloaded software is way better than online software. If you haven’t paid for your TurboTax Online filing yet, you can buy TurboTax from Amazon or Costco and switch from TurboTax Online to TurboTax download.

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 TurboTax.
Go to Federal Taxes -> Wages & Income -> IRA, 401(k), Pension Plan Withdrawals (1099-R).
When you come to the Retirement Income section, answer Yes because you received a 1099-R from your 401(k) plan.
Yes, you received a 1099-R form. Import the 1099-R if you’d like. I’m typing it myself here.
You have a normal 1099-R.
If you import the 1099-R, check the import carefully to make sure it matches your copy exactly. If you type the 1099-R, be sure to type it exactly. The earnings portion should be in box 2a. Box 2b “Taxable amount not determined” should NOT be checked. The after-tax non-Roth contributions (the “principal”) should be in box 5. Box 7 should show a code G. Finally, the box “The IRA/SEP/SIMPLE box is checked on my copy of the 1099-R” should NOT be checked.
TurboTax wants to make sure the IRA/SEP/SIMPLE checkbox is not checked.
Choose Yes when you rolled over the money within the plan.
Confirm that you made after-tax non-Roth contributions to your plan.
If your 1099-R is correct, the amount of your after-tax non-Roth contributions shows up in box 5 and TurboTax pulls it up here. If your 1099-R isn’t correct, you should work with your 401(k) administrator to have it corrected.
Not a public safety officer, unless you actually are one.
The summary shows your 1099-R entries.
Not affected by a disaster.
When you see TurboTax moving on to a totally separate topic, in our case Social Security Benefits, you know that’s the end of reporting your mega backdoor Roth. Now let’s confirm you’re only paying tax on the $200 earnings, not on your $10,000 after-tax non-Roth contributions.
Click on Forms on the top right.
Find “Form 1040” in the left navigation pane. Scroll up or down in the right pane to lines 5a and 5b. Line 5a includes the $10,200 gross distribution amount. Line 5b only includes the $200 taxable amount. With a mega backdoor Roth, you got an extra $10k into your Roth account. After paying tax on this $200, the future earnings on the $10,200 going forward will be tax-free.
When you’re done examining the form, click on Step-by-Step on the top right to get back to the interview.
Withdraw to Roth IRA
Now let’s look at the mega backdoor Roth variation when you withdraw the after-tax non-Roth contributions plus earnings to a Roth IRA. 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 a Roth IRA, your contributions earned $200. You rolled over $10,200 to your Roth IRA.
The steps in TurboTax are the same as rolling over to the Roth account within the plan until this question:
When you took the money to a Roth IRA, you answer No here.
Confirm that the money went to a Roth IRA.
Confirm that you made after-tax non-Roth contributions.
If your 1099-R is correct, the amount of your after-tax non-Roth contributions shows up in box 5 and TurboTax pulls it up here. If your 1099-R isn’t correct, you should work with your 401(k) administrator to have it corrected.
After this point, the interview follows the same path as rolling over to the Roth account within the plan. Please scroll up and follow there. I’m not repeating them here.
In the end, Form 1040 will show the same as rolling over within the plan. Line 5a includes the $10,200 gross distribution amount. Line 5b only includes the $200 taxable amount. With a mega backdoor Roth, you got an extra $10k into your Roth IRA. After paying tax on this $200, the future earnings on the $10,200 going forward will be tax-free.

Sangeeta says
Hi Harry,
Thanks a lot, you are a wonderful and knowledgeable teacher. But here you have mentioned only @ 401K plan –Mega door if it allows. While you were on vacation I had left you a question on another link on your spreadsheet calculations for Business income Mega door Roth amount.I am still waiting for an answer on that.
Thanks
Harry Sit says
Sangeeta – I answered it there.
Shane says
Hi Harry,
How does this work if you want to split the after tax contribution from the earnings so the after tax amount goes to Roth IRA and the earning goes to Traditional IRA?
Thanks.
Harry Sit says
You get two 1099-Rs.
Brian says
Problem is when you roll your after-tax contributions to a Roth IRA and after-tax gains into a Solo 401k.
Turbo treats the gains as taxable and puts them into 16b.
Any solution for this?
Brian says
Also:
Fidelity only sent one “combined” 1099-R. I had extensive discussions with Fidelity and they claim this is correct. Fidelity claims it’s a Turbo issue.
The gains are a non-trivial amount of money, since I just quit my job and had gains from many years of after-tax contributions.
Harry Sit says
Try entering the 1099-R as two, one for the amount gone into Roth and another for the amount gone into traditional.
Brian says
Good idea. As long as the IRS computers aggregate all of my 1099-Rs and match against an aggregation of all of my 5498s, it will be correct (if they try to match one-for-one, it will get kicked out as not matching).
Thanks TFB, I’ll give that a shot.
I like that idea much better than Turbo’s suggestion that I alter Box 5.
Hongyan says
Hi Harry,
When I transferred my after-tax 401k to my Roth IRA account, they made a mistake and put my money into my traditional IRA account instead of my Roth IRA account. Then I transferred it to my Roth IRA account. Therefore I received two 1099-R with same amount of money (one from the 401k institution, and the other from the IRA brokerage firm). Based on your Turbotax walkthrough, what differences should I do to make sure both 1099-R are covered? Thank you very much!
Harry Sit says
It would’ve been best to correct the mistake when it happened as opposed to letting it stand and building up on the mistake.
Now, it depends on who made the mistake and how exactly you transferred the money to your Roth IRA. If the 401k provider processed your request to rollover to a Roth IRA as a rollover to a traditional IRA, which matched what actually happened, AND you did the transfer as a recharacterization (not a conversion), you don’t have any problems. You just enter two 1099-Rs separately. If you did the transfer as a conversion AND you don’t have other traditional, SEP or SIMPLE IRA that creates a pro-rata issue, you also don’t have any problems. If you did the transfer as a conversion AND you do have other traditional, SEP or SIMPLE IRA, you run into a pro-rata issue which makes you pay tax on the conversion.
If the 401k provider processed it correctly as a rollover to a Roth IRA but your IRA provider deposited the money into a traditional IRA, you have a mismatch between paper and reality. If you subsequently did the transfer as a conversion, you have a potential issue with paying tax twice. The 401k provider’s 1099-R says you should pay tax because you rolled over to Roth. The IRA provider’s 1099-R says you should pay tax because you converted from traditional to Roth.
See Traditional and Roth IRA: Recharacterize vs Convert.
Hongyan says
Hi Harry,
Thank you so much for the detailed response! My 401k provider somehow did not include my roth IRA account number when sending the check to the IRA provider so the IRA provider intuitively deposited the check into my traditional IRA. The transfer from traditional IRA to Roth IRA is done as a conversion (without pro-rata issue). May I ask how do I find out whether the 401k provider processed the check correctly as a rollover to a roth IRA or not? The 1099-R they sent to me has code G in box 7. Does it mean they did it correctly?
So if my case creates the “mismatch between paper and reality” situation, what can I possibly do? Sorry for my multiple questions and thank you for your patience and help!
Harry Sit says
If the 1099-R from the 401k provider looks like the one in this post, with a small taxable amount in box 2a and your after-tax contribution in box 5, the 401k provider did it correctly. It would be rare to have two mistakes on top of each other and end up matching the reality. Although the check didn’t include your Roth IRA account number, it likely included the word ‘Roth’ there. Contact your IRA provider and ask for a copy of that check. If it had the word ‘Roth’, that’s your proof the IRA provider made the mistake and it gives you reason to ask them to correct that mistake. In order to correct it, they may ask you to recharacterize your conversion first, which makes the money go back to the traditional IRA. Then the IRA provider can do whatever is necessary on their end to move it into the Roth IRA again the right way, where it should’ve landed in the first place.
Hongyan says
Hi Harry,
Thank you. I called the IRA provider and they only claims that they will send out form 5498 in May to show that the distribution amount in their 1099R is from a rollover, which should “offset” the taxable amount. I don’t know whether it is true and it did not help me with my tax return using turbotax at this moment either. I think I might go to a CPA instead.
Harry Sit says
It’s not true. Get the copy of that rollover check and show them they put it in the wrong account. Get them to correct it. A CPA won’t help if the IRA provider doesn’t correct it because the CPA can’t change reality. A CPA can help you with the paperwork to report the reality only *after* the IRA provider corrects it.
Harry Sit says
Also try contacting your 401k provider to see if they can send you a copy of that rollover check.
Hongyan says
Hi Harry,
Thank you for all the advice. I really appreciate it! It turned out the 401k provider forgot to mention anything about my Roth account. I will try to go to my IRA provider tomorrow and talk to them one more time to see if any correction is possible. My distribution is about 7k and double tax means paying ~2k more for me!!
Harry Sit says
In that case ask your 401k provider whether they can redo your 1099-R to make it a rollover to traditional because they didn’t mention anything about Roth to the receiving end. When they do a rollover to Roth they are supposed to say Roth.
Hongyan says
Hmm, it sounds quite doable. I will definitely try it tomorrow. But I guess I am still a little confused. After the 401k provider redo the 1099R to make it a rollover to traditional IRA, I assume this 1099R will not make me pay tax at all (for the entire distribution including the small amount of earnings, is it correct?). But for the 1099R from IRA provider, how do I make sure I only get taxed on the small earnings? This 1099R from IRA provider looks exactly like the one you would get by doing backdoor Roth as shown in your post “How To Report Backdoor Roth In TurboTax”.
Another question is, in this case can I still use turbotax for tax return or I will have to find a CPA to get it done properly?
Thank you.
Harry Sit says
Correct. The only difference is box 2a will show 0 for a rollover to traditional. You just enter the two 1099-Rs independently. On the IRA conversion one when it asks you about your basis, you put in the number in box 5 from the 401k 1099-R. TurboTax can still do it.
Hongyan says
Hi Harry,
I see. I think this will solve the problem. Thank you Harry for all the advice and quick response!
Future Proof MD says
Thanks Harry, great post! I have a question regarding my SEP IRA account. Do I have to “hide” that balance when performing a Mega Backdoor Roth IRA from my 403b account? In other words, do I trip the pro-rata rule if I have a SEP IRA when doing a Mega Backdoor Roth conversion?
Harry Sit says
Not if you go directly from 403b to Roth IRA. You trip it when you make an interim stop at a traditional IRA.
Rose says
Thank you for this great visual explanation!
I have a question about the step which asks for the after-tax contributions. In 2017 I contributed about $15k after-tax, but since my plan only allows quarterly in-plan Roth conversions I ended up only being able to rollover $12k to my Roth 401k, which is what is listed on my 1099-R in box 5. Do I keep this $12k as listed since that was what actually went into my Roth 401k, or list what my actual after-tax contributions were during 2017 ($15k)?
Thanks again!
Harry Sit says
Only the $12k as shown on your 1099-R. Please note for an in-plan rollover to Roth 401k you would answer ‘Yes’ to the question after the 1099-R entries and follow from there. The screens aren’t the same as a rollover to a Roth IRA shown here.
Sachin K says
Thank you for this detailed post. I did this for 2016 returns and did not see a Form 8606 being prepared by TurboTax. Is Form 8606 necessary in this case? If yes then probably I need to amend my 2016 returns.
Harry Sit says
You don’t need a Form 8606 when you go from the plan directly to the Roth IRA.
Hari S says
Thank you for the excellent articles on this site! It has really helped me learn a ton!
Back in 2016, when I first made the after-tax contributions to my 401k (about $5k), I wasn’t entirely sure on how to do the traditional/roth conversions – so I got scared and simply requested a withdrawal and encashed the check received. I didn’t have any earnings/losses from this – so I thought “since I had already paid taxes on the contributions (they are after tax contributions after all), there was nothing here for me to report on form 1040” – so I left boxes 16a and b on form 1040 blank. However, I just received a notice from the IRS yesterday, showing this $5k amount as taxable and ordering to pay back taxes of $2k. However, the 1099-R clearly shows the $5k in boxes 1 and 5 and box 2a shows $0. Is it enough for me to simply fax this copy of my 1099-R to them to remove the charge? Or do I need to offer more explanations? Or do I really owe taxes? FWIW, I am much much younger than 59.5 years.
Appreciate everything that you do!
Hari
Harry Sit says
You don’t really owe taxes. Call the number on the notice and ask them what they need. They will probably want a written explanation.
Hari S says
Called them up, they said all they want is the 1099-R’s showing the $0 in box 2a.
Peter says
My employer allows me to split my conversion sending earnings via trustee to trustee transfer to my traditional IRA. However, they insist on direct depositing the original contribution into my checking account. I then send the funds to Vanguard with a letter of explanation. For the traditional portion I receive a 1099-R with a distribution code G. All is good. But for the portion I send to my Roth (original non-Roth after tax contributions) I receive another 1099-R with a distribution code of 1 (early distribution with no know exception). Is my employer reporting this correctly?
walle says
Hello,
Please help. I am doing this exactly as shown. I transferred some 15k to Roth from my employers after tax account. The 1099B shows no tax withheld with box 1 matching box 5 and box 7 has code G.
After I answer yes to contributing on a After Tax basis to my 401k and confirm the amount on the next page my tax owed goes very high. I think they are taxing this 15k. Dont know what to do here now…! 🙁
Harry Sit says
If Box 5 matches Box 1 exactly, put 0 in Box 2a instead of leaving it blank.
Walle says
That was it! I figured it out by trial and error but you are correct, I was leaving it blank. My 1099R does have a zero so it was just me. Blank does not mean zero 🙂 Thank you for confirming and your post; it has been very helpful!
greg says
Just wanted to say thanks for the very detailed walk through.
first time reporting it and I found it a little confusing.
the “unless” bits helped greatly and the 1040 example was perfect.
Thank you.
Michelle says
Hi Harry – thank you so much for the visual explanations! I have some questions regards to 1099R forms. Sorry in advance for a long comment.
I received 2 1099Rs from Fidelity, which is my 401k provider and which I have Roth IRA with (do not have a TIRA). In 2018, I did both Mega backdoor Roth and Roth in Plan Conversion. After reading your post, I think Fidelity might have incorrectly filled out 1 of 2 1099Rs.
1) This 1099R is for the Roth in Plain conversion and I think this is correct
Box 1 15,300
Box 2a 89
Box 5 15,211
Box 7 code G
2) I think this 1099R is for mega backdoor
Box 1 10,896
Box 2a 0
Box 5 10,496
Box 7 code H
Q1. Shouldn’t box 2a be 400 (10,896-10,496) since earning is taxable for mega backdoor?
Q2. Also, should the code be G, not H according to your explanations above? (But H is a direct rollover from a designated Roth account distribution to a Roth IRA so that also sounds right…)
Q3. Form 5498 I received has different rollover contribution (12,095) from above numbers on 1099R. Is this correct?
Could you be able to tell if I received correct 1099Rs? Thank you very much!
Harry Sit says
A “designated Roth account” is the official name for what we usually call a Roth 401k. If you distributed from the Roth 401k account to the Roth IRA, that explains why box 2a is zero. If you distributed from the non-Roth after-tax account, code H is wrong, and box 2a should be box 1 minus box 5. I have no idea why the number on the 5498 is different.
Ryan says
This article was exactly what I was looking for! Even years after it was written, it’s still helping people. I’ve just started after-tax contributions to my 401k and plan on rolling over to my roth IRA; however, with the recent market activity, I would be doing it at a loss (just a couple hundred dollars). If I were to roll over now, would the loss be reported on the 1099-r and could be applied to compensate other short-term gains?
Thank you!
Harry Sit says
The loss will not be reported on the 1099-R. Some 401k administrators retain the loss within the 401k. If your next rollover has a gain, it can be offset by the loss. Some administrators simply treat the loss as zero gain. Because the assets can lose value again after you roll over, you are not any worse off by rolling over now versus if you had rolled over a month ago.
Ryan says
Got it. Thank you for your response. Very much appreciated!
Leah says
Hi Harry, this is exactly what I’m looking for! Just one quick question: I have both pre tax 401K and after tax 401K under the same plan and my plan allows in service distributions, when I convert after tax 401k to Roth IRA, do I have to follow pro-rated rule to recalculate taxable portion vs non-taxable portion? Or it’s just like that all after tax contributions are non-taxable income and earnings are taxable? Thank you in advance!
Harry Sit says
Most plans allow you to request in-service distribution only from the after-tax account. Make sure you make that crystal clear in your request. In that case, the pro rata rule is only applied within the after-tax account: earnings will be distributed together with after-tax contributions. The after-tax contributions are non-taxable and the earnings are taxable. However, some plans require pro-rated distribution across both pre-tax and after-tax accounts. They are rare but they still exist. You have to find out how your plan operates.
Rebecca says
Great summary, but I have one quick question: when asked “Did you make any after-tax contribution to your 401k plan? These would be contribution you made into the plan yourself, rather than being made by your company on your behalf.” Should I answer “yes” if I made after-tax contributions via payroll (i.e.: the same way my regular contributions are made, but after-tax (not Roth) – employer sends to 401k administer)? Thanks again for the great tutorial.
Harry Sit says
Yes, it’s included in the screenshots.
Loren says
Hi Harry – what an old post but really helpful today. On Turbo Tax it says that “this isn’t common, but this is money you put in the plan yourself, not from your company.” My after tax contribution which is then converted to Roth 401k, is from wages & income (payroll). Wouldn’t the answer be “No”, since it is from my company? Thanks!
Harry Sit says
It is from payroll but it’s out of your pocket, not the company’s pocket.
Joe says
Hi Harry,
My 401-k plan allows for mega backdoor Roth conversion and I plan to use it starting in 2021. However, my company wants me to convert my after-tax 401-k contribution into Roth 401-k the _following_ calendar year after I contribute to the after-tax 401-k because they want to make sure they pass the nondiscrimination test. Meaning if I fund the after-tax 401-k in 2021, they want me to convert in 2022 and this also means I will have to pay taxes on the gains up to the point of conversion.
I have also been doing backdoor Roth IRA on my own. If I do both the mega backdoor Roth conversion in 2022 and also do the backdoor Roth IRA in 2022 (contribute and convert in 2022), would I receive two 1099-R’s? And are there any complications when filing taxes, or just work through each 1099-R in the software?
Thank you!
Harry Sit says
Converting in the following year is fine. After you pay taxes on one year’s worth of earnings, the future earnings will still be tax-free. Yes, if you do both the regular backdoor Roth and the mega backdoor Roth, you will receive two 1099-R’s — one from your IRA custodian, and another from your 401(k) plan. They’re unrelated. You do them independently. I have walkthroughs for both.
Bob says
Hi Harry,
I am using TT Online, and I do exactly as you have described here for my Roth rollover ( did the same past few years). TT does everything correctly but does not put the word ‘ROLLOVER’ on line 5b. I have submitted a ticket with TT and waiting for their reply. Do you know about this issue with Online version? I have already paid for the TT and trying to see whether I can get a refund so that I can get the desktop version.
Thanks
Bob
Harry Sit says
I don’t know about it in the online version. Hope they’ll fix it in an update.
Ron says
I have the desktop software version and it doesn’t show ‘rollover’ either. Maybe is ok to leave it blank?
Harry Sit says
If you followed the steps exactly it should show, as in my screenshot. Check the code in box 7 in your 1099-R. Is it ‘G’?
Bob says
yes, the code is G. And yes, I followed your steps exactly as you have described. This is my 5th year I am doing this, so I double checked it to make sure I did it your way.
Here are the details of my 1099-R:
Box1: $27039.08
Box 2a: $0.00
Box 2b: Not Checked
Box5: $27039.08
Box 7: G
IRA: Not Checked
Harry Sit says
I tried in my copy. It seems if the Box 5 number exactly matches the Box 1 number and the taxable amount in Box 2a is zero, the word “ROLLOVER” doesn’t appear. If Box 5 is slightly smaller and there’s a small taxable amount in Box 2a, the word “ROLLOVER” appears, as in my example. I don’t know why TurboTax does it that way. Maybe that’s just how the IRS wanted and TurboTax is simply following the instructions.
bob says
I tried reducing Box 5 to $27000 and adding $39 to 2a, still the word ‘ROLLOVER’ does not appear, but it did calculate correct taxable amount.
Thanks for trying Harry.
Richard Sharon says
Bob/Ron – Did you find anything more on this. Looks like I am in the same situation. TurboTax Desktop doesn’t put “ROLLOVER” on line 5b for me as well, likely because 1099-R’s Box 5 number matches Box 1, and Box 2a is 0. Appreciate any input. Thanks
Ron says
For a mega backdoor roth, will I need to fill out the ‘Traditional and Roth IRA Contributions’ section in the ‘Deductions and Credits’ section? Or just the steps you listed in this article is sufficient?
Harry Sit says
If you made the contribution to your 401k through payroll, as described in the example, just the steps here are sufficient. If you contributed to Traditional and/or Roth IRA on your own, that’s separate.
Michael says
Hi Harry, Thank you for your explanation. I’m using Credit Karma to file. Box 5a looks correct per your instructions although it doesn’t say “ROLLOVER” anywhere; however the taxable amount is showing up in 4b instead of 5b. Is this an issue?
Thanks,
Michael
Harry Sit says
If you did a transaction similar to the examples here, it’s clearly a distribution from a retirement plan, not from an IRA. The taxable amount should be on line 5b, not on line 4b.
Justin says
Michael, I’m having the exact same issue with Credit Karma. Did you figure out how to get the amount to go to line 5b?
Thanks,
Justin
Justin says
Looks like it can’t be done on Credit Karma Tax. Their support said: “We currently don’t support a taxable event for code G ‘Direct Rollover and rollover contribution’ in Box 7. So, if this is considered taxable for you we don’t currently support this situation.”
Harry Sit says
FreeTaxUSA can do it. It’s free for Federal and $13 for the state if you need it. See How To Enter Mega Backdoor Roth in FreeTaxUSA.
Leonel says
Hey Harry, great article! I have been trying to make sense of my taxes this year, where I converted an old employer 401K to a Traditional IRA which I then backdoor converted into a ROTH IRA. My financial institution told me that doing this over going straight from a 401K to ROTH would be best, since I would owe taxes on the amount but not owe any penalties for “over-contributing”. However, I am having a hard time reporting this on TurboTax without avoiding penalties, where I have a 401K 1099-R, IRA 1099-R, IRA 5498 and ROTH IRA 5498.
Harry Sit says
Your transactions have nothing to do with the topic here. It sounds like you entered IRA contributions with your two 5498 forms. Delete them. A rollover or a conversion isn’t a contribution.
CL says
Hi Harry,
Thanks for your guidance on this. Have you tried this with H&R Block software? I get the exact same answers, except that the word ROLLOVER is not printed on line 5. I can’t get the word to show regardless of rollover into a Roth IRA or designated account. Any thoughts? Is it critical?
Harry Sit says
I tried it in H&R Block software. The process is similar. The word “ROLLOVER” doesn’t print on line 5 for me either. The 1040 instructions say it should be there. I don’t know how critical that is.
“Enter on line 5a the distribution from Form 1099-R, box 1. From this amount, subtract any contributions (usually shown in box 5) that were taxable to you when made. From that result, subtract the amount of the rollover. Enter the remaining amount on line 5b. If the remaining amount is zero and you have no other distribution to report on line 5b, enter -0- on line 5b. Also enter “Rollover” next to line 5b.”
mervinj7 says
Thanks, Harry. Are you going to post similar screenshots for H&R Block?
Harry Sit says
I wasn’t planning to, but I might as well for completeness. Please check back next week.
Arunodoy Saha says
Hi Harry,
Thanks a lot- it was so useful. 2 things:
1. I have 1099-R type G and type – H both.
Now, according to your example, I am contributing 10000$ from paycheck which converts to roth 401k – and may be it gained 200$ before the conversion happened (I recieved type G form for the above) which shows 200$ taxable income.
Now the same 10200$ is again being converted to an outside IRA. and I receive 1099-R type H form- it shows 0$ taxable.
My problem is when I add these 2 forms in turbo tax, it shows up as 20200$ as pension distribution.
Pros: I do see “ROLLOVER” which is same as you described and taxable income is also 200$
cons: IRS will see I rolled over 20200$ – whereas I actually contributed 10000$ which got converted twice and hence showing double.
2. I was first using turbotax online and did not see as many questions as u mentioned- so I bought a turbotax deluxe pc download version. I see same number of questions for type -G form but for type-H form, it does not ask for whether this money was moved to a roth IRA which is very important and I think that is the reason behind double of 10000$
Any advice?

If you actually did two rollovers, first from the after-tax account to the Roth 401k account, and later from the Roth 401k account to a Roth IRA, it’s normal to have the sum of two gross amounts on Line 5a. 1099-R code ‘H’ means “Direct rollover of a designated Roth account distribution to a Roth IRA.” It’s clear enough the software doesn’t need to ask more questions.
It’s not necessary to do two rollovers if this is with your current employer. If you intend to move the money to your Roth IRA, you can rollover directly from the after-tax account in the 401k to your Roth IRA. But maybe you first rolled over to the Roth 401k, and you moved the Roth 401k to your Roth IRA after you left the employer.

Thanks for a very quick reply!!
I am still with the same employer- just that I am doing it in 2 steps as mentioned. Now will I be in trouble as it looks like due to this ‘double down’ of same money, I am recording an extra value with IRS for record keeping?
For mega backdoor conversion, the total allowed amount is 57k per year (401k + employer + post tax converted amount) – I think I am crossing the limit of 57k if they count the ‘doubled’ rollover.
Harry Sit says
Doing two rollovers won’t get you in trouble but it created extra work and extra worry. If the plan makes it convenient to rollover within the plan and you like the convenience, do that and leave the money in the Roth 401k account until you change jobs. The $57k limit counts contributions, not rollovers.

Great article. I’m having an issue with TT related to this. I have an in-plan rollover, and in the “review” at the end, it’s telling me that in Line 6a, “Taxpayer elective deferrals to individual 401k plans and to roth 401k plans should not be greater than 19500.” Apparently it’s summing my individual contribution ($19.5k) and my backdoor roth ($31k) and flagging the sum for being over the limit. Is this a TT issue? Or should I not enter the backdoor roth amount as a contribution when TT is asking me what retirement contributions I made during the year because it’s not a “normal” Roth contribution?
Harry Sit says
You should not enter the non-Roth after-tax contributions when TurboTax asked you what retirement contributions you made for the year.
Erik says
I wish my plan administrator replied as quickly as you do, thanks Harry. 🙂 So basically, I should change my elective deferral for the Roth 401k from $31k to 0, and that will solve the issue, correct? As a follow-on question, my administrator sent me a 1099-R that has box 2b checked and nothing in box 5 – is that correct? Seems to contradict what you have here.
Harry Sit says
Try it in TurboTax and see what difference it makes. I don’t know whether that’s an equally valid way to do the 1099-R when your administrator doesn’t know how much non-Roth after-tax money you contributed (and therefore “taxable amount not determined”). I only know my 1099-R doesn’t look like that.
Erik says
Yeah, the difference seems to be Box 2b. If it’s checked and I then say I moved the money from a 401k to a Roth, my small refund turns into me owing $11k. If it’s unchecked, the only way I can keep my refund from changing into me owing is if I say “no I didn’t” when it asks if I moved the money from a 401k to a Roth 401k. I don’t know if that’s technically accurate but this should nevertheless not be a taxable event so I’m trying to get to the end result (and the correct one) I desire. Waiting to hear back from my plan administrator on the 1099-R. The fact is they know exactly how much after-tax money I contributed because I sent them a signed form that attested to the deposit.
Erik says
As a follow-up, yep, administrator was mistaken. They fixed it and I was able to submit everything. Thanks for your help!
Loren says
Thanks Harry. Whenever TurboTax says it’s an uncommon situation, I tend to default my response. Based on your logic I would have thought it would be uncommon for the company to make an after-tax contribution Not the other way around, but I must be wrong. Appreciate the clarification.

Harry,
A quick question: if I contributed $20,000 to After tax 401K in 2020 but only rolled over $15,000 to Roth IRA later in the same year, what contribution amount should I put in box 5? The total contributions of $20K made in 2020, or the contributions of $15K shown on 1099-R? Thanks!
Harry Sit says
Your 401k plan provider tracks the earnings on the after-tax contributions. They allocate part of the distribution to your after-tax contributions and the rest as taxable earnings. Suppose your $20,000 contributions grew to $25,000 before you requested to roll over $15,000. 80% of the after-tax account was your contributions ($20k / $25k). Therefore 80% of the $15,000 distribution was your contributions. Your 1099-R will show $15,000 distribution, $3,000 taxable, $12,000 in box 5.
Leah says
Thanks for your quick response! No realized gain occurred as I invested in money mkt funds. So here $20K and $15K are purely contributions. So my question really is: If we contributed more than what we rolled over to Roth IRA, what contribution amount should we put on tax return? The total 2020 contributions of $20K or the contributions of $15K that was rolled over to Roth IRA? This is a question to a scenario where conversion and contributions didn’t line up. Thanks!
Harry Sit says
Box 5 shows the non-taxable portion of the rollover. If you had zero earnings, it’s equal to the rollover amount.
Leah says
Thank you!! So box 5 will show the contributions from 1099R. What about the following question after I answered that I made after tax contributions to this 401k. It is asking to input After tax contributions to 401K or 403B. Should I put the same amount as box 5 or the total contributions that was made in 2020? ( say $20K contributions in total and $15K contributions converted to Roth IRA)
Harry Sit says
All the questions pertain to the distribution. Of this distribution, how much were your after-tax contributions. Your total contributions not in this distribution are not relevant.
Leah says
Very helpful!! Thanks so much for sharing your tax knowledge on this matter!

Hi Harry
1 Such contribution check for In Plan Roth conversion, should go out from Employee or Employer a/c
2 If mega backdoor Roth contribution bring down Net pay close to zero, will that cause any issue
3 How does it reflect in W2. Net pay close to zero and contribution goes in 12 D value AAA
