If you’ve been sleeping on the Roth 401(k), it’s time for a second look. Yes, they used to come with that inconvenient drawback known as the Required Minimum Distribution (RMD), where you had to withdraw money on a set schedule, whether you needed it or not. But with the implementation of the SECURE 2.0 Act, RMDs are no longer required. Add to this a new rule for catch-up contributions, and Roth 401(k)s just became much more attractive, especially for high earners.
No RMDs Means More Control
Before this change, the IRS required you to start withdrawing money from your Roth 401(k) once you hit a certain age, which forced retirees to pull funds out of an account that would otherwise keep growing tax-free.
Now that both Roth IRAs and Roth 401(k)s are free from RMDs, they’re on a level playing field. This gives you control. If you want to leave your money in the account and let it grow, you can. You have the freedom and flexibility to time withdrawals based on your needs, not a government schedule.
Key Differences Between Roth 401(k) and Roth IRA
Both accounts offer tax-free growth and tax-free withdrawals in retirement. But they are not identical, and the differences are important.
With a Roth IRA, you can only contribute up to $7,500 annually in 2026 (or $8,600 if you’re 50 or older). There’s also an income limit. For 2026, the limit is $153,000 for single filers and $242,000 for joint filers. If you earn too much, you’re not eligible to contribute at all.
A Roth 401(k) doesn’t have those restrictions. The contribution limit is $24,500 in 2026, and there is no income limit.
So for higher earners, the Roth 401(k) is the more accessible option.
A New Rule for Catch-Up Contributions
As of January 1 of this year, under the SECURE 2.0 Act, catch-up contributions for employees who are 50 or older and earn over $150,000 must go into a Roth 401(k). You can no longer direct those extra contributions into a traditional 401(k). That means paying taxes now on those catch-up contributions instead of later.
This might feel constricting for some people, but it’s not a bad deal in the long run. Yes, you’ll pay taxes on contributions now, but the growth and withdrawals remain tax-free.
Why This Matters for High Earners
Put it all together and the Roth 401(k) starts to look like the better option for high earners. You can contribute more than a Roth IRA allows, and you won’t be excluded due to income limits. Your money grows tax-free, and when you withdraw it, you don’t owe taxes on the gains. This can be significant if your balance grows over decades.
Then there’s the question of future tax rates. Many people assume they’ll be in a lower tax bracket in retirement, but when you factor in required withdrawals, Social Security income, and other assets, this isn’t always the case. Some retirees may even end up in higher tax brackets. A Roth 401(k) helps avoid that risk.
To recap, no RMDs, higher contribution limits, and no income restrictions make Roth 401(k)s a strong option. And now, if you’re a high earner making catch-up contributions, you’ll be in a Roth account whether you planned for it or not. Hopefully, now you can start to see why that’s actually a good thing.
