As retirement planning strategies continue to evolve, changes to Roth 401(k) rules under the SECURE 2.0 Act are driving meaningful tax and planning considerations. If you’re saving for retirement with a Roth 401(k), it’s important to understand what’s changing now and what’s on the horizon.

No More Required Minimum Distributions for Roth 401(k)s
One of the most impactful updates is the removal of required minimum distributions (RMDs) for designated Roth 401(k) accounts. Under prior rules, Roth 401(k)s were treated like traditional 401(k)s when it came to RMDs — meaning account holders had to begin withdrawing funds at age 73 (or later under future age schedules) even though qualified withdrawals are tax-free.

Thanks to the SECURE 2.0 Act, RMDs no longer apply to Roth 401(k)s. This change brings Roth 401(k)s into the same RMD-free treatment previously reserved for Roth IRAs, allowing your money to potentially grow tax-free for longer. For many savers, this means greater flexibility in retirement and the ability to keep assets working for you without being forced to take taxable distributions simply due to age.

Employer Matching Can Now Go Directly Into Your Roth Account
Another important shift affects employer contributions. Traditionally, employer matches tied to Roth 401(k) contributions were deposited into a traditional (pre-tax) 401(k) account. Now, employers generally have the option to deposit matching funds directly into your Roth 401(k).

While this can be beneficial because those contributions grow tax-free and can be withdrawn tax-free in retirement, it does come with a current tax consequence: employer Roth match amounts are treated as taxable income in the year they are made. If your employer adopts this approach in 2025, you can expect that added income to be reflected on your 2025 W-2, which you receive in early 2026.

Some savers may view this as a worthwhile trade-off for future tax-free growth, but it’s important to plan for the potential increase in taxable income today.

Catch-Up Contributions Must Be Roth for High Earners Starting in 2026
The SECURE 2.0 Act also changed the rules for catch-up contributions. For 2025, high-income earners (those with wages above $150,000 in the previous year) can still make catch-up contributions on a pre-tax basis. Beginning January 1, 2026, however, catch-up contributions for these high-wage employees must be made on an after-tax (Roth) basis.

This means that beginning with 2026 contributions, higher earners will pay taxes upfront on catch-up amounts, foregoing the immediate tax deduction they might previously have claimed. However, since contributions are Roth, qualified withdrawals in retirement can be tax-free.

Contribution Limits for 2025
For the 2025 tax year, contribution limits to 401(k) plans (including Roth 401(k)s) remain generous:

Under age 50: You can contribute up to $23,500 to your 401(k).
Ages 50–59 and 64+: You can make an additional catch-up contribution, bringing the total to $31,000.
Ages 60–63: Thanks to the “super catch-up” provision, you may contribute up to $34,750 total, combining the standard limit with the higher catch-up allowance.

Remember, you must make contributions by December 31 of the plan year for them to count toward that year’s limits.

What This Means for You
The recent Roth 401(k) rule changes give you more control and flexibility over your retirement savings. Eliminating RMDs lets you hold on to funds longer, potentially extending tax-free growth well into retirement. The option for employer matching to Roth accounts can enhance your tax-free income picture in the future — but it’s important to factor in the tax impact today.

Planning around these changes can help you take full advantage of available benefits and better align your retirement strategy with your long-term financial goals.
