401(k) Catch-Up Contributions: The Complete 2025–2026 Guide to SECURE 2.0 Changes

Everything plan sponsors and participants need to know about catch-up contributions, super catch-ups for ages 60–63, and the mandatory Roth requirement for high earners.

Last Updated: January 2026

Catch-up contributions have long been one of the most powerful tools for pre-retirees to accelerate their retirement savings. If you're 50 or older, you can contribute beyond the standard 401(k) limit, and SECURE 2.0 just made this benefit even more valuable for certain age groups.

But SECURE 2.0 also introduced significant compliance requirements that plan sponsors must address before 2026. This guide covers everything you need to know: the new contribution limits, who’s affected, what plan sponsors must do, and how participants can maximize their savings.

What Are Catch-Up Contributions?

Catch-up contributions allow employees age 50 and older to defer additional amounts beyond the standard annual limit. For 2026, the standard 401(k) deferral limit is $24,500. If you're 50 or older, you can contribute an additional $8,000, for a total of $32,500.

The rationale is simple: people closer to retirement often have more disposable income (kids are grown, mortgage is paid down) and less time to save. Catch-up contributions help them make the most of their remaining working years.

Eligibility Requirements

• You must be age 50 or older by December 31 of the calendar year
• Your plan must permit catch-up contributions (most do)
• You must have already contributed up to the standard limit, or your catch-ups “spill over” once you hit it

2025 and 2026 Contribution Limits

SECURE 2.0 introduced inflation adjustments and new age-based tiers. Here's the complete breakdown:

The Super Catch-Up: Ages 60–63 (Effective 2025)

One of SECURE 2.0’s most impactful provisions is the enhanced catch-up limit for participants ages 60 through 63. Beginning in 2025, this group can contribute the greater of $10,000 or 150% of the regular catch-up limit which, works out to $11,250 for 2025.

Why These Ages?

The 60–63 window represents peak earning years for many professionals and the final stretch before typical retirement. Congress recognized this as a critical savings window, hence the enhanced limit.

Important: Once you turn 64, you revert to the standard catch-up limit. This creates a narrow four-year window to maximize contributions. A participant who takes full advantage from ages 60–63 could contribute an additional $45,000+ in catch-ups alone.

Is the Super Catch-Up Mandatory for Plans to Offer?

No. The IRS has confirmed that the enhanced age 60–63 catch-up is optional. Plans that permit standard catch-up contributions for those 50+ are not required to offer the higher limit for ages 60–63.

However: If one employer in a controlled group adopts the super catch-up, all other plans in the group must also offer it under the “universal availability” requirement. Plan sponsors in multi-entity structures should coordinate carefully.

Mandatory Roth Catch-Up for High Earners (Effective 2026)

This is the provision that requires the most attention from plan sponsors. Beginning January 1, 2026, participants who earned more than $150,000 in FICA wages from their employer in the prior year must make all catch-up contributions on a Roth (after-tax) basis.

How It Works

1. Payroll looks at each employee’s prior-year W-2 Box 3 (FICA wages)
2. If Box 3 exceeds $150,000, that employee is flagged as a “high earner”
3. All catch-up contributions for that employee must be designated Roth
4. Standard deferrals (up to $24,500) remain pre-tax or Roth at the employee’s choice

Consider the Roth Advantage

If you’re required to make Roth catch-ups (or choose to voluntarily), remember the benefits: tax-free growth, tax-free qualified withdrawals, no required minimum distributions (as of 2024), and income-tax-free inheritance for beneficiaries.

The Bottom Line

SECURE 2.0’s catch-up contribution changes represent both opportunities and obligations. For participants ages 60–63, the super catch-up creates a powerful four-year savings window. For high earners, mandatory Roth catch-ups open a door to tax-free retirement growth that income limits had previously closed.

For plan sponsors, the message is clear: ensure your plan is ready for 2026. If you don’t offer Roth contributions, add them. If you haven’t communicated the changes to participants, start now. The deadlines are real, and the consequences for non-compliance, particularly for high-earning employees and business owners, are significant.
