In September 2025, the U.S. Department of the Treasury and the Internal Revenue Service finalized regulations implementing key provisions of the SECURE 2.0 Act related to catch-up contributions in workplace retirement plans.
These final rules bring much-needed clarity but also introduce new compliance responsibilities for employers, plan administrators, and higher-income employees.
Here’s a straightforward breakdown of what’s changed, what’s confirmed, and how to prepare before the rules take full effect.
What Is the Roth Catch-Up Requirement?
Under SECURE 2.0, employees aged 50+ who make catch-up contributions and earn above a certain income threshold must now make those contributions as Roth (after-tax) instead of pre-tax.
In simple terms:
Higher-income employees can still contribute extra, but those contributions will be taxed upfront.
The final regulations clarify:
- Who qualifies as a “higher-income” employee
- How income is measured
- How employers must apply the rule in practice
What Changed in the Final Regulations?
After feedback from employers and industry groups, several important updates were made:
Aggregated Wages Across Employers
Plan administrators can now aggregate wages from related employers (in certain cases) to determine whether an employee exceeds the income threshold.
Clearer Correction Procedures
Updated guidance explains how to fix errors if Roth catch-up rules aren’t applied correctly.
Refined “Deemed Roth Election” Rules
If an employee doesn’t explicitly choose Roth, plans may treat contributions as Roth under defined conditions.
Puerto Rico Plan Considerations
Special provisions have been included for plans covering participants in Puerto Rico.
Increased Catch-Up Limits: A Key Opportunity
SECURE 2.0 doesn’t just add restrictions it also creates new opportunities.
Employees aged 60 to 63 will be eligible for higher catch-up contribution limits, allowing them to boost retirement savings during peak earning years.
There are also updates affecting SIMPLE plan participants, especially in newer plans.
Bottom line:
More flexibility but also more complexity in administration.
Effective Dates: What’s the Latest?
- The Roth catch-up requirement will apply to taxable years beginning after December 31, 2026
- Some plans (like governmental or collectively bargained plans) may have later implementation timelines
- The transition relief period under IRS Notice 2023-62 still ends December 31, 2025 (no extension announced as of now)
As of 2026, no major delays have been announced, so firms should continue preparing for the 2027 implementation.
What You Should Be Doing Right Now
Whether you’re an employer, advisor, or plan administrator, preparation is critical.
Update Plan Documents
Ensure your retirement plans reflect Roth catch-up requirements and new contribution limits.
Review Employee Income Thresholds
Determine which employees will be impacted, especially across related entities.
Align Payroll & Systems
Make sure systems can correctly process Roth contributions and handle corrections if needed.
Educate Employees Early
Many employees won’t expect this change clear communication is essential.
Train Internal Teams
Payroll, HR, and compliance teams must understand how these rules work in practice.
Why This Matters More Than It Seems
This isn’t just a technical tax update.
It represents a broader shift toward:
- After-tax retirement savings (Roth)
- Greater compliance complexity for employers
- More responsibility for plan administrators
Firms that prepare early will avoid last-minute issues, while those that delay may face operational and compliance challenges.
Final Thought
The IRS, under the SECURE 2.0 Act Roth catch-up rules, brings clarity but also requires action.
With 2027 approaching, now is the time to:
- Review your plans
- Update your systems
- Educate your stakeholders
Because when these rules take effect, there won’t be much room for error.
