In other articles I showed that contributing to after-tax 401k/403b and rolling it over to Roth IRA (the “mega backdoor Roth”) is great if your 401k/403b plan allows it. It’s still worth it even if you have to wait a few years before you can roll it over to Roth. You should still do it even if it drops your paycheck next to nothing. If you are self-employed, it may be worth paying a modest fee to enable this feature.

A new question is, wouldn’t it lock your money up until you are 59-1/2?
What if you want to use your money before you are 59-1/2 because you will retire early or buy a house? If you just invest in a regular taxable account, you can tap your money anytime you want and you only pay capital gains tax. Do you lose flexibility if you push all your money into your Roth IRA?
Yes and no. It’s time to get familiar with Roth IRA’s ordering rules for distributions.
First of all, as you know, one great feature of Roth IRA is that you can withdraw your regular [direct] contributions at any time with no tax or penalty. Any money you withdraw from your Roth IRA is considered to come from your regular contributions first. If you need money before 59-1/2, you can always withdraw up to the sum of your regular contributions. However, if you haven’t been able to contribute directly to Roth IRA due to the income limit, this amount may not be much.
Second, everything is forgiven after 59-1/2 AND you have had any Roth IRA for 5 years. After that point it doesn’t matter how the money came into the Roth IRA; all withdrawals are tax free.
You are left to worry about withdrawing money above the sum of your regular [direct] contributions before age 59-1/2. The withdrawals go by this order:
- money you converted to Roth (including rollover from after-tax 401k/403b), first-in first out; and
- earnings on both your regular contributions and the converted money
If you wait 5 years before you withdraw your converted money, you are again forgiven. No tax, no penalty.
If must withdraw within 5 years (remember first-in first out), you look at how much of the conversion you paid tax on at that time. For example if you contributed $10,000 to your after-tax 401k and by the time you rolled it over to Roth it grew to $12,000, you paid tax on $2,000 when you rolled it over. Withdrawing this $12,000 within 5 years will have you pay a 10% penalty on the $2,000 but you don’t pay income tax on the $12,000. That comes out to paying $200 to withdraw $12,000, which is less than 2%.
If you had very little earnings when you rolled over, or if you did a split rollover (earnings went to a traditional IRA), withdrawing within 5 years will have you pay a 10% penalty on very little, or possibly zero.
Finally, earnings on both your regular contributions and the converted money are indeed locked up until 59-1/2, with some limited exceptions. After you exhaust all your converted money, withdrawing earnings before 59-1/2 will be taxable and subject to a 10% penalty.
Does doing the mega backdoor Roth lock up your money? For post-rollover earnings, absolutely. For your after-tax rollover itself, not much at all. If you stack up the rollovers and you always withdraw money from more than 5 years ago, there is no tax nor penalty. Even if you have to withdraw your after-tax rollovers within 5 years, you only pay 10% on the small amount of pre-rollover earnings. 10% on a small amount is very small. 10% of zero is still zero.
Bottom line, you still have good access to your money before age 59-1/2 when you do the mega backdoor Roth.

TFB, Great article – but don’t forget that the IRS allows for penalty free withdrawals from Qualified Plans (Not IRA) at age 55 or 50 in certain scenarios. Another reason why diversification in assets types is huge when facing distribution needs.
“The following additional exceptions apply only to distributions from a qualified retirement plan other than an IRA:
Distributions made to you after you separated from service with your employer if the separation occurred in or after the year you reached age 55, or distributions made from a qualified governmental defined benefit plan if you were a qualified public safety employee (State or local government) who separated from service on or after you reached age 50.”

Don’t forget that you can invoke the 72(t) provisions once you start tapping into the earnings portion of your Roth IRA, assuming there are enough to provide income for 5 years or more. You won’t be subject to the 10% penalty if you receive a series of substantially equal periodic payments, or “SOSEPP,” from your IRA for the greater of five years or until you reach 59-1/2. If you have traditional IRA accounts, you might be better off tapping into those with SOSEPP instead.

Thanks for the great article. I’m going to be trying this next year and was glad to learn how accessing the funds early would work.
$iddhartha says
My employer allows me to put 10% of salary into “normal” 401k and 8% into after-tax. Thinking that there was little benefit to after-tax contributions, I had been putting money towards my own student loans instead.
Here’s a college savings scenario I haven’t heard discussed as it relates to this topic. I have two kids under age 2, and this seems like the ideal tool to save for their college expenses. I live in a state that does not allow pretax contributions to a 529 plan. Combine that with the fact that colleges don’t look at parents’ retirement accounts for financial aid purposes, and there is little incentive for me at all to use a dedicated 529 plan.
Great series of articles TFB. The mega backdoor Roth will without a doubt benefit my long-term goals. I just wish the rules weren’t so convoluted that only certain people can take advantage of them.
Harry Sit says
One advantage of a 529 is that you can use earnings tax free for college expenses whereas you can only withdraw the “principal” from the Roth IRA. I would still prioritize this mega backdoor Roth over a 529 plan.
Rod says
TFB I have a question for your consideration if you please.
Assuming that my 401k investment options are as good or better than what I would have on a Roth IRA, and I don’t need to tap into the after-tax contribution in the foreseeable future, do you see an advantage of still doing After-tax -> Roth IRA, instead of After-tax -> Roth 401k?
I read that (in California) 401k funds have better legal protection vs IRAs, I can also perform a Roth 401k -> Roth IRA rollover when I leave my company (or reach 59 1/2) without any penalty so I can “resume the Roth IRA avenue”. Last but not least, because I already have a Roth IRA open, when/if I rollover the Roth 401k I would not lose the 5-years log from the 401k Roth.
Thank you
Harry Sit says
Rod – It those assumptions hold true and your 401k plan can isolate the source when you do an in-plan rollover, making it after-tax -> Roth 401k, I don’t see a problem.
Rod says
TFB thank you.
Yes the plan is setup in a way that it can clearly identify 3 different “source groups”, one of them being after-tax. It is not setup to allow me for different fund allocation between 401k and Roth 401k but that’s a lesser problem since I’m applying a common allocation % to both accounts.
Caleb says
Hi Harry,
Thanks for the article. I’ve been looking into Mega-Backdoor for my upcoming bonus. It seems that according to the letter of the law, withdrawing an after-tax 401(k) backdoor conversion to Roth should incur no tax liability (assuming no gains on what was rolled over). Let’s go back to your 10k to 12k example. Let’s say instead of withdrawing $12,000, I withdraw $10,000. Do I incur a penalty of (10/12) * $10,000? Or is the $10,000 withdraw safe from any penalty?
Does the IRS require you to somehow specify if you are only withdrawing previous contributions or if the earnings are being withdrawn? Are there any tax-filing implications of making a contribution only withdraw from a Roth?
When I looked at trying to withdraw contributions from my Roth IRA from Vanguard they said the transaction would be reported to the IRS. Any idea what that means for me?
Thanks for any answers you can give.
Harry Sit says
Within that $12k, the $2k in pre-conversion earnings comes out first. If you withdraw only $10k you still pay penalty on $2k. This is different from withdrawing direct contributions.
Stephen says
Are these rules the same for the Roth 401K? Or to access the Roth 401K while still working, I would have to roll over the contribution amount I wanted to access to a Roth IRA, then access from there? Also for the Roth IRA, do you have to have separate accounts for each year? As you say it is FIFO, meaning any earning must come between yearly contributions so to access the second contribution you would have to go through the earnings as well? Or is it all contributions first then earnings?
In https://thefinancebuff.com/roth-ira-contributions-withdrawals-spreadsheet.html, it seems to say all contributions first correct?
Harry Sit says
Rules are not the same for Roth 401k. No withdrawals or rollovers from Roth 401k are allowed before 59-1/2 when you are still working for that employer. After you terminate, rules become similar.
For Roth IRA, FIFO only applies to conversions. Direct contributions come out first.
Dave Anderson says
Great article. I’m a retirement plan advisor – mostly larger plans. I recently had a smaller employer/client approach me about this. This is a safe harbor 401k plan with a Roth feature. My understanding is that after tax contributions count toward ACP testing – even in a safe harbor plan. My fear is this is a relatively complex concept to communicate – one that may be utilized primarily by highly compensated employees and, in turn, likely cause the Plan to fail testing.
Your thoughts would be appreciated!
Harry Sit says
That’s correct. It may not work for a smaller employer. You can do a mock testing with some assumptions and see how the plan can pass.
