Catch Up Contributions Final SECURE 2.0 Rules for Employers
As employers and plan sponsors prepare for 2026, one of the most significant retirement plan changes under the SECURE 2.0 Act affects catch-up contributions — the extra retirement savings opportunity for employees age 50 and older. The IRS has now issued final regulations that clarify how these catch-ups must be handled, especially for higher-earning participants. Here’s what employers need to know to stay compliant and effectively communicate these changes to your workforce. IRS+1
What Are Catch-Up Contributions?
Catch-up contributions are additional elective deferrals that participants aged 50 or older can make beyond the regular 401(k) contribution limits. These are designed to help employees accelerate retirement savings as they near retirement. Under SECURE 2.0, both the amount and tax treatment of these contributions are evolving. IRS
Key Changes Under the Final SECURE 2.0 Rules
1. Mandatory Roth Treatment for Certain High Earners
Starting with plan years beginning in 2026, catch-up contributions made by employees who meet certain income criteria must be treated as Roth contributions — meaning after-tax contributions that grow tax-free and can be withdrawn tax-free in retirement. IRS+1
Who is affected?
Employees age 50 or older whose prior-year FICA wages from the employer exceed a threshold (IRS guidance uses ~$145,000, indexed annually). IRS+1What does this mean for employers?
Plans must ensure catch-up contributions by these employees are automatically designated Roth if the plan permits Roth contributions, or the plan must permit Roth catch-ups to allow these employees to contribute at all. Thomson Reuters TaxGood-faith transition period:
Although the mandate technically begins in 2026, final regulations give employers through 2027 to fully implement operational and system changes while applying a reasonable, good-faith compliance standard.
Why this matters: If a plan does not offer Roth contributions, participants subject to the Roth requirement may not be able to make any catch-up contributions until Roth options are available — making it essential for plan sponsors to assess plan design and communication. Thomson Reuters Tax
2. Higher Catch-Up Limits for Ages 60–63 (“Super” Catch-Up)
SECURE 2.0 also expanded catch-up savings limits for older workers: Plans may permit higher catch-up contribution limits for employees ages 60–63 — often referred to as “super catch-ups.
These higher limits exceed the standard catch-up amount for participants aged 50–59, giving those closer to retirement a bigger window to save. IRS
Important note: Offering the “super” limit is optional; if a plan chooses to adopt it, it must ensure consistent application across similarly situated participants.
Operational and Compliance Considerations
As an employer and plan fiduciary, these changes raise several important operational and compliance tasks:
✅ Plan document review and amendment — Confirm that the plan allows Roth catch-up contributions (and super catch-up limits, if adopted).
✅ Payroll and recordkeeping system updates — Ensure platforms can distinguish elective deferrals vs. catch-up deferrals and properly designate Roth status based on income thresholds.
✅ Participant communication and education — Prepare clear guidance to employees on how the rules apply, especially around tax effects of Roth vs. pre-tax contributions.
✅ Testing and monitoring — Validate systems for handling the new rules by year-end and coordinate with recordkeepers/payroll vendors on implementation timing.
These administrative burdens are a key reason regulators provided a compliance cushion and a reasonable good-faith standard for early adoption.
Communicating With Your Workforce
When educating employees:
📌 Emphasize that the tax treatment of catch-up contributions may change — higher earners will now contribute after-tax dollars but benefit from tax-free withdrawals later.Ascensus
📌 Explain the income threshold and how it’s determined (typically based on prior-year Form W-2 Box 3 FICA wages).
📌 Clarify options for participants whose employers do not yet offer Roth contributions. Thomson Reuters Tax
Clear communication will help employees understand why the change matters and how it affects their personal retirement planning choices.
Bottom Line for Employers
The final SECURE 2.0 regulations on catch-up contributions represent one of the most impactful retirement plan changes in years — particularly for employers sponsoring 401(k), 403(b) and governmental 457(b) plans. The shift toward mandatory Roth treatment for higher-income catch-up contributions forces both plan design evaluation and operational readiness by the 2027 compliance deadline, even though the rules technically take effect in 2026.

By updating plan documents, payroll systems, and employee education resources now, employers can smooth the transition and continue to support meaningful retirement outcomes for participants nearing retirement.
