A New 401(k) Rule Takes Effect in 2027 - And Higher Earners Over 50 May Not Like It

If you're 50 or older, you've been getting an extra tax break when putting more money into your 401(k). Starting next year, that break is changing for some high-earning workers.

A new rule requires certain employees to make their 401(k) catch-up contributions as Roth contributions instead of traditional pre-tax contributions. While you could still save more for retirement, you may lose the immediate tax deduction on those extra dollars.

For workers in their peak earning years, the change is meaningful. Here's what the new rule means, how it affects your retirement plan, and whether there's still a good reason to max out your 401(k).

What changes in 2027

Under the new rule created by the SECURE 2.0 Act, certain higher-earning 50-and-older workers who are eligible to make catch-up contributions must make them as Roth contributions rather than traditional pre-tax contributions. The IRS's final regulations generally apply the requirement to contributions made after December 31, 2026.

The IRS's administrative transition period for the Roth catch-up requirement ended December 31, 2025. However, the new Roth requirement did not broadly take effect in 2026. Plans could implement the Roth catch-up requirement before 2027 using a reasonable, good-faith interpretation of the law. So, some workers may have encountered the change earlier. Still, 2027 is the general applicability date under the final regulations.

Only some 401(k) contributions have to be Roth. Regular elective deferrals on a traditional pre-tax basis are still possible if your plan allows them. The new rule applies specifically to the catch-up portion for workers who meet the income threshold.

In practice, this means that some older workers must pay today's income tax on their catch-up contributions instead of getting the tax deduction upfront.

Who does the Roth requirement apply to?

Generally, workers could be subject to the Roth requirement in 2027 based on their 2026 wages, even if their income falls somewhat in 2027. They must be eligible to make Roth 401(k) catch-up contributions and must have had employer-reported wages above the applicable threshold in the previous calendar year.

For 2026, the threshold is $150,000. It is adjusted for inflation, and the rule also depends on the retirement plan.

What happens to the immediate tax deduction?

In short, the government is moving the tax benefit from today to retirement. For example, if you're 55 and your employer's 401(k) allows $8,000 as a catch-up contribution, the money goes into the Roth side of your 401(k). Before, it generally wasn't included in your taxable income for the year.

The change may feel like a pay cut even though you're adding the same amount into retirement. The tradeoff is that Roth contributions provide tax-free qualified withdrawals later. Qualified distributions generally aren't subject to federal income tax if you meet the Roth 401(k) requirements, including the applicable five-year rule and age requirement.

Why Roth contributions aren't necessarily bad news

Giving up an immediate tax deduction may sound painful, especially during your peak earning years. But Roth money has a major advantage: You pay the tax now, and qualified withdrawals in retirement are generally tax-free.

That could be valuable if you expect to be in a similar or higher tax bracket later. The Roth requirement may frustrate those who want the tax deduction today, but it doesn't mean the money is going into an inferior account.

How much can you contribute?

Workers who are at least 50 by the end of the calendar year may contribute beyond the regular annual 401(k) elective-deferral limit if their plan permits catch-up contributions. For 2026, the regular 401(k) limit is $24,500, and the standard catch-up limit is another $8,000.

That means someone age 50 or older could generally contribute up to $32,500 in 2026, before considering employer contributions and other plan-specific rules. The important point is that the new Roth rule changes the tax treatment, not the basic opportunity to save extra money for retirement.

The larger catch-up available at ages 60–63

Starting in 2025, workers who turned 60, 61, 62, or 63 during the year could make a larger catch-up contribution to most 401(k), 403(b), and governmental 457 plans. For 2026, the higher catch-up limit is $11,250, compared with $8,000 for most other workers age 50 and older. The limit is subject to future cost-of-living adjustments.

So, a 61-year-old worker could potentially have considerably more room to fund a retirement plan than a 55-year-old worker.

Should you still max out your 401(k)?

For many higher-earning workers, the answer is yes.

The Roth requirement doesn't make the contribution itself less valuable. It simply changes when you receive the tax benefit.

As long as the contribution doesn't compromise other financial priorities, continuing to save the maximum available could result in more money invested for retirement and more tax diversification later.

Bottom line

The takeaway here is that the tax break is changing, not your ability to save. The new Roth catch-up requirement may be frustrating if you've been using your 401(k) contributions to lower your financial stress by reducing your taxable income.

But the change doesn't affect how much eligible workers may save. Instead, it shifts the tax benefit: You pay the taxes now, potentially in exchange for tax-free qualified withdrawals later.

If you're affected by the new rule, check how much your take-home pay would change if you made Roth catch-up contributions. Then, consider whether you still want to contribute the maximum. If you do, make sure your 401(k) plan offers a Roth option and learn how your employer plans to handle the change.
