401(k) Catch-Up Contributions Are Changing in 2026: What High Earners Need to Know

401(k) Catch-Up Contributions Are Changing in 2026: What High Earners Need to Know

If you’re age 50 or older, you’ve probably heard about or taken advantage of 401(k) catch-up contributions: the extra amount you can save on top of the standard limit each year. These contributions are a powerful way to build retirement security, especially in your final working years.

But starting in 2026, there’s a big change coming. Thanks to the SECURE 2.0 Act, certain higher-income earners will be required to make their 401(k) catch-up contributions as Roth contributions, meaning you’ll pay taxes now instead of later (IRS Final Regulations).

Here’s everything you need to know about the new 2026 401(k) catch-up contribution rule, and how to prepare.

What Are Catch-Up Contributions?

For 2025, the IRS has set the 401(k) contribution limit at $23,500 which is the maximum amount most employees can put in through salary deferrals (401k limit increases).

If you’re age 50 or older, you can save even more. The IRS allows an extra $7,500 catch-up contribution, raising your total possible 401(k) contribution in 2025 to $31,000 (401k limit increases).

Traditionally, these catch-up contributions could be made on a pre-tax basis (reducing your taxable income today) or as Roth contributions (after-tax, but tax-free later).

The 2026 Rule: Mandatory Roth for High Earners

Starting in 2026, if you earned $145,000 or more in FICA wages in the prior year, your 401(k) catch-up contributions must be made as Roth (IRS Final Regulations).

• FICA wages are the earnings on which you and your employer pay Social Security and Medicare taxes. In most cases, this means your salary or wages from your employer, not investment income or retirement account withdrawals.

Basically, if you’re a high earner age 50+, your catch-up dollars will no longer reduce your taxable income today. Instead, they’ll grow tax-free in retirement.

Why the Change?

Congress included this provision in SECURE 2.0 for two main reasons:

1. Raise tax revenue now: Contributions taxed up front provide immediate federal revenue.
2. Promote Roth savings: Roth accounts ensure future withdrawals are tax-free, simplifying revenue forecasts for the government.

What If Your Plan Doesn’t Offer a Roth?

This rule introduces a real roadblock for affected workers. If your employer’s 401(k) plan does not currently offer a Roth contribution option, you may be unable to make catch-up contributions at all once the new rule takes hold.

Under SECURE 2.0 and the IRS final regulations, if a plan offers catch-up contributions and has participants subject to the mandatory Roth catch-up rule, then all catch-up-eligible participants (i.e. age 50+ in that plan) must be allowed to make catch-up contributions as Roth contributions, even if they don’t meet the high-income threshold. (IRS Final Regulations on Roth catch-up rule).

In other words: plans that want to continue offering catch-up contributions must add a Roth option. If they don’t, they effectively block catch-up contributions for those who fall under the new rule.

How This Impacts Your Retirement Plan

If you’re earning above $145,000, here’s what this means for your planning:

• Expect higher taxable income – You’ll lose the immediate deduction on catch-up contributions.
• Shift your tax strategy – Now is the time to weigh Roth vs. Traditional strategies.
• Confirm your plan options – Make sure your employer offers Roth contributions, or you may miss out on catch-up eligibility.
• Explore other accounts – HSAs, IRAs, and taxable accounts can add flexibility if 401(k) options are limited.

The Bottom Line

The new 401(k) catch-up contribution rule starting in 2026 is a significant shift. While it takes away an up-front tax break, it strengthens Roth savings, providing future tax-free income.
