He Checked the “Roth” Box on His 401(k) Enrollment Form at 45 and Never Thought About It Again. At 73, When Everyone He Knew Got Their First RMD Letter, His Never Came
Most Roth 401(k) owners spent decades following the same rules as everyone else, never realizing a single checkbox buried inside the tax code quietly exempted them from a retirement obligation that catches thousands of savers off guard every year.

If you checked the “Roth” box on your 401(k) enrollment form and kept feeding it for decades, here is the payoff almost nobody advertised: your designated Roth 401(k) no longer forces you to take a required minimum distribution during your lifetime. Not at 73. Not at 75. Not ever. That is the buried rule most participants still do not know about, and it quietly rewrote the RMD playbook for every Roth 401(k), Roth 403(b), and Roth 457(b) balance in the country.
What Actually Changed in 2024
Before 2024, the Roth 401(k) carried a strange flaw. A Roth IRA never required you to touch it while you were alive. The Roth 401(k) did, forcing retirees into an uncomfortable choice: draw down a tax-free bucket they had no desire to shrink, or roll the whole balance into a Roth IRA before their required beginning date just to escape the distribution. Neither option was clean.
That workaround is now unnecessary. Since 2024, there is no legal requirement to pull money from a Roth 401(k) at any age. If you turned 73 this year and every pre-tax saver you know just received a first RMD letter, yours never arrived because the plan has nothing it is legally obligated to distribute.
The Statute Behind the Silence
The change flows from Section 325 of the SECURE 2.0 Act, which amended Internal Revenue Code Section 401(a)(9) to exclude designated Roth accounts inside employer plans from the pre-death RMD rules. The IRS confirmed the mechanics in Notice 2024-02, with an effective date of taxable years beginning after December 31, 2023. That is the primary source: an actual statute in the tax code, not a regulatory interpretation.
A related change reinforces this advantage from the contribution side. Beginning January 1, 2026, SECURE 2.0 Section 603 requires workers aged 50 or older who earned more than $150,000 in FICA wages in 2025 to route all catch-up contributions into the Roth bucket. The rule was originally scheduled for 2024 but received a two-year IRS delay. Now that it is in effect, affected savers are being pushed into Roth treatment whether they planned for it or not. The longer-term payoff: more Roth dollars accumulating inside the plan, all exempt from lifetime RMDs.
Who Gets the Free Pass, and Who Does Not
The exemption applies to designated Roth balances inside a 401(k), 403(b), or governmental 457(b). It covers your Roth contributions, any in-plan Roth conversions, and the earnings on both. The pre-tax side of your 401(k) is a different matter entirely: those balances still trigger RMDs starting at age 73 under SECURE 2.0, rising to age 75 in 2033. The exemption also does not reach a SEP or SIMPLE IRA. And it stops at the account owner’s death: a beneficiary who inherits the account remains subject to distribution rules under the 10-year payout regime.
How to Actually Lock It In
Three concrete steps:
- Pull up your latest 401(k) statement and confirm the “designated Roth” subaccount balance appears separately from the pre-tax balance. If your plan lumps them together on the summary page, call the recordkeeper and ask for the Roth-only figure. Only the Roth portion is exempt from RMDs.
- If you are still contributing in 2026, the numbers are straightforward. The standard elective deferral cap is $24,500, with an $8,000 catch-up available at age 50 and older, for a combined maximum of $32,500. Workers aged 60 to 63 qualify for an enhanced “super” catch-up of $11,250, pushing the total to $35,750. If you earned more than $150,000 in FICA wages from your plan sponsor in 2025, your catch-up must go into the Roth bucket starting this year. That is inconvenient at tax time but builds more lifetime-RMD-free assets for the future.
- Think carefully before rolling a Roth 401(k) into a Roth IRA out of habit. Both are now RMD-free during your lifetime, but the 401(k) retains stronger creditor protection under ERISA and cleaner five-year clock treatment if you have held it since day one. The old reason to roll over no longer applies; the calculus now favors staying put in many cases.
The Catches Nobody Mentions
Two traps deserve attention. First, the exemption belongs solely to the account owner. The moment your heirs inherit, the RMD clock restarts under the SECURE Act 10-year rule, and a non-spouse beneficiary will generally have to empty the Roth 401(k) within a decade. The account passes tax-free, but not distribution-free.
Second, if you had already begun Roth 401(k) RMDs in 2023 or earlier under the old rules, you were allowed to stop in 2024. Plans had a transition window, and some participants continued taking distributions by mistake. Check your 2024 and 2025 Form 1099-Rs. If your plan pushed a Roth RMD out to you after January 1, 2024, that was a distribution you did not owe. You cannot always put the money back, but you can stop it going forward. This is one of a handful of quiet IRS rules that steadily drain retirement accounts, and we mapped the rest of them in a free tax trap guide here.
One box on one form, nearly three decades ago. That is the whole trick.
Editor’s note: This article was updated to reflect the mandatory Roth catch-up contribution rule that took effect January 1, 2026, under SECURE 2.0 Section 603, including the $150,000 FICA wage threshold (indexed from the $145,000 statutory base per IRS Notice 2025-67) and the confirmed 2026 contribution limits of $24,500 base deferral, $8,000 standard catch-up, and $11,250 super catch-up for ages 60 to 63.
