We live in a world where two things are true. First, more investors are using the Roth 401(k) to save and invest for retirement. Second, as demonstrated by the strength of the financial independence movement, many are interested in retiring early by conventional standards.
Some potential “early” retirees are thinking about the so-called “Rule of 55” and many of them have Roth 401(k)s.
How does the Roth 401(k) work with the Rule of 55? Is there a better option than the Rule of 55 for those looking to retire using in part or in whole a Roth 401(k) prior to turning age 59 ½?
We will explore both the Roth 401(k) and the Rule of 55, then we will discuss planning involving the potential combination of the Roth 401(k) and the Rule of 55. We will also discuss a planning alternative to combining the Roth 401(k) with the Rule of 55.
Roth 401(k)
The Roth 401(k) is a 401(k) that is taxed as a Roth. Employers offering a 401(k) are not required to offer a Roth 401(k) option, but many do.
Roth 401(k) Contributions
There are now three main potential sources of “Roth contributions” to a Roth 401(k).
- Employee Deferrals: In 2024, these are limited to the lesser of earned income or $23,000 ($30,000 if age 50 or older). These are done through W-2 withholding into the Roth 401(k).
- Mega Backdoor Roth: These are after-tax contributions by the employee (also through W-2 withholding) to the traditional 401(k) followed by a soon-in-time Roth conversion of the after-tax 401(k) amount to the Roth 401(k).
- Employer Contributions: Employers contribute to 401(k)s. SECURE 2.0 allows for employers to contribute to Roth 401(k)s. Traditionally, employer contributions had always been to the traditional 401(k), but SECURE 2.0 established the possibility of Roth 401(k) employer contributions. Note that a February 2024 federal court decision has called SECURE 2.0 into question.
There’s a limit on the combination of 1 plus 2 plus 3. I refer to this limit as the “all additions limit” and some refer to it as the “415(c)” limit, as that’s where the limit lives in the Internal Revenue Code. For 2024, the all additions limit is $69,000. For those aged 50 or older, it is $76,500.
Note that Roth IRAs cannot be rolled over to a Roth 401(k).
There’s a fourth potential source of Roth 401(k) funds: Taxable conversions from traditional 401(k)s. Taxable Roth conversions (traditional 401(k) to Roth 401(k)) have no limit. These are usually not done during one’s working years.
Roth 401(k) Withdrawals
If “done right” a Roth 401(k) withdrawal in retirement is fully tax and penalty free.
However, if a distribution from a Roth 401(k) occurs before either (or both) the account owner is 59 ½ years old or the owner has owned that particular Roth 401(k) for five years, the “earnings” portion of the distribution is subject to ordinary income tax and the potential 10 percent early withdrawal penalty.
Here’s a quick example illustrating that rule:
Ken is age 53. He’s early retired. At a time when his Roth 401(k) is worth $200,000 and he’s previously contributed $100,000 to it, Ken takes a $50,000 distribution from the Roth 401(k) to help fund his retirement. Fifty percent of the distribution ($25,000) is a return of Ken’s previous contributions and fully tax and penalty free. The other fifty percent of the distribution ($25,000) is earnings and since Ken is under age 59 ½ will be taxable to Ken and subject to the 10 percent early withdrawal penalty.
Rule of 55
The Rule of 55 is an exception to the 10 percent early withdrawal penalty. It applies to a specific employer’s qualified plan, such as a 401(k). It applies distributions from an employer’s qualified plan if
- The qualified plan account owner separated from service from the employer no earlier than the beginning of his or her age 55 birthday year, and
- The distribution occurs after the separation from service.
Here is an example:
Rob was born on June 7, 1969. On January 16, 2024, Rob retired from Acme Industries. 2024 is Rob’s 55th birthday year. Any distribution occurring after January 16, 2024 from the Acme Industries 401(k) to Rob qualifies for the Rule of 55 exception to the 10 percent early withdrawal penalty.
Note that a transfer from the former employer’s qualified plan to an IRA blows qualification for the Rule of 55. Distributions from an IRA are not distributions from the employer’s qualified plan. Further, the Rule of 55 applies only to the particular employer’s plan. If Rob had separated from Consolidated Industries at age 52 and still had a 401(k) there, distributions from that 401(k) would not qualify for the Rule of 55.

Planning
Perhaps you’re sitting at home saying “Roth 401(k)s are great. The Rule of 55 is great. Why not combine them?”
I have four reasons not to combine them.
Taxing Roth 401(k) Earnings
Paying tax on a Roth distribution is the planning equivalent of breaking into jail. Combining the Roth 401(k) with the Rule of 55 means taxing Roth earnings as ordinary income. That isn’t a great outcome, particularly when there was no tax deduction on the way into the Roth 401(k).
Here is an example:
Ted leaves Maple Industries at age 56. He withdraws $60,000 from his Maple Industries Roth 401(k) at a time it was worth $300,000 and had $120,000 of previous contributions. Forty percent of the withdrawal ($24,000) is a tax and penalty free return of contributions. Sixty percent of the withdrawal ($36,000) is penalty free under the Rule of 55 but is subject to income taxation.
Perhaps a significant portion of the taxable withdrawal is protected by the standard deduction (what I refer to as the Hidden Roth IRA in the context of traditional retirement account withdrawals). But even at a 10 or 12 percent marginal federal income tax rate, from a planning perspective having any sort of taxable distribution from a Roth account is a bad outcome.
Further, taking money out of a Roth in our 50s means foregoing additional years or decades of tax free growth on that money.
A Great, Easily Accessible Alternative Exists
Before age 59 ½, a Roth 401(k) represents a challenge and an opportunity for an early retiree.
First, the challenge. The challenge is the “cream-in-the-coffee” rule I previously discussed in this post. Distributions before age 59 ½ attract both old contributions and earnings. Earnings are subject to both ordinary income tax and the 10 percent early withdrawal penalty.
Here’s an example:
Moe is age 53. He has a $500,000 Roth 401(k). $200,000 is old contributions and $300,000 is growth on those contributions (earnings). If Moe takes a distribution of $10,000 from the Roth 401(k), $4,000 (40%) will be a tax and penalty free return of contributions and $6,000 (60%) will be a distribution of earnings, subject to both income taxation and a 10 percent early withdrawal penalty (add 2.5% if Moe lives in California).
Here’s the opportunity: Someone like Moe can “isolate” his $200,000 of Roth 401(k) basis and avoid taxation on his Roth withdrawals.
It’s pretty easy. Moe can simply transfer his entire Roth 401(k) to a Roth IRA. That will immediately give Moe $200,000 of “basis” in his Roth IRA (old annual contributions which can be removed at any time for any reason tax and penalty free). Once the Roth 401(k) is in a Roth IRA, Moe has $200,000 (plus any other Roth basis he has separately built up) he can withdraw entirely tax and penalty free for early retirement.
A Good, Not Too Difficult Alternative Exists
There’s another path to basis isolation and avoiding taxation on a Roth 401(k) distribution, but it will be more complicated. This path involves Moe keeping most of the money inside the Roth 401(k).
Returning to the facts of Moe’s example: Say Moe is 53 years old and early retired. If the Roth 401(k) plan allows partial pre-age 59 ½ withdrawals, and Moe wants $10,000 tax and penalty free, he could withdraw $25,000 from the Roth 401(k) and (i) keep $10,000 (40%) and (ii) transfer $15,000 (60%) to a Roth IRA. The transaction will be entirely tax and penalty free as Moe is deemed to get the basis ($10,000) distributed to him and to have transferred the earnings ($15,000) to his Roth IRA. See Exception 3: Roth 401(k) Withdrawal then Rollover in this post for more details.
Why Not Use Taxable Accounts, if Possible?
I’ve said it before and I’ll say it again: I prefer using taxable accounts, if possible, to fund retirement prior to using retirement accounts. While that will not be possible for everyone, why not save before retirement in a manner that facilitates (1) living off taxable accounts prior to age 59 ½ (and pay very low capital gains taxes) while (2) doing very low tax rate Roth conversions in retirement.
Obviously, there’s only so much tax planning anyone can do if they are in their mid-to-late 50s and a couple of months away from retirement. But for those in their 30s, 40s, and even early 50s, now is the time to plan to set up a retirement that is as tax advantageous as possible.
For anyone with a decent amount of time between now and retirement, I would not recommend planning into relying on using the Rule of 55 for a Roth 401(k).
ACA Premium Tax Credit Considerations
I’m concerned that some people take the Roth too far. If you get to retirement prior to age 65 and need to go on an ACA medical insurance plan, having every last penny in Roth accounts is not a good place to be. It can mean that you’re not able to generate taxable income in retirement, meaning you can’t qualify for a significant Premium Tax Credit against hefty ACA insurance premiums.
In theory, the Rule of 55 could be a workaround to that problem. Imagine Jane retires at age 56, and other than a paid off house and $50,000 in a savings account she has a $2,000,000 Roth 401(k) and a $500,000 Roth IRA. How is she going to create any taxable income to qualify for the Premium Tax Credit?
The answer, for a few years, can be the Rule of 55. Jane could take from her Roth 401(k) (assuming it allows partial pre-age 59 ½ distributions), create taxable income on the “earnings” portion of the distribution as discussed above, and avoid the 10 percent early withdrawal penalty under the Rule of 55.
This is still not something that should be planned into. Why not? At age 59 ½, assuming Jane has had the Roth 401(k) for 5 or more years, she will qualify for a “qualified distribution” from the Roth 401(k), meaning that all distributions from it will be entirely tax free.
That’s bad news from a Premium Tax Credit perspective: at that point Jane will have hardly any taxable income (just some interest income from the small savings account) and thus will not generate sufficient income to qualify for the Premium Tax Credit!
Conclusion
It is good that the Roth 401(k) and the Rule of 55 are available options for retirement. Absent unique and extreme circumstances, they generally should not be combined when it comes to retirement planning.
