Navigating Roth Catch-Up Contributions Under SECURE 2.0
The SECURE 2.0 Act introduced significant changes to retirement savings rules, and one of the most impactful—yet widely misunderstood—provisions involves Roth treatment of catch-up contributions. This change affects higher-income participants in 401(k) and similar retirement plans and has important tax, administrative, and planning implications.
“The Roth catch-up provision under SECURE 2.0 marks a meaningful shift in retirement plan design and tax strategy for higher-income workers. While it removes some flexibility, it also creates new opportunities for tax-free retirement income.”
What Are Catch-Up Contributions?
Catch-up contributions allow employees aged 50 and older to contribute additional dollars to their retirement plans beyond the standard annual deferral limit. These contributions are intended to help individuals accelerate savings as they approach retirement.
Historically:
Catch-up contributions could be made on a pre-tax or Roth basis (depending on plan design)
Many participants chose pre-tax treatment to reduce current taxable income
SECURE 2.0 changes this flexibility—but only for certain individuals.
The New Roth Catch-Up Requirement
Under SECURE 2.0, catch-up contributions must be made as Roth contributions (after-tax) if certain conditions are met.
Key Rule
Beginning in 2026 (delayed from an original 2024 effective date):
Participants with prior-year wages over $150,000 (indexed for inflation)
Must make all catch-up contributions as Roth contributions, if their plan permits catch-ups
This applies to:
401(k) plans
403(b) plans
Governmental 457(b) plans
If a participant earns at or below the threshold, they may still choose between pre-tax and Roth catch-up contributions (subject to plan rules).
Important Clarifications
1. The Threshold Is Based on W-2 Wages
The $150,000 threshold:
Applies only to FICA wages from the employer sponsoring the plan
Does not include income from other employers, self-employment, or investment income
This means:
A high-income individual with multiple jobs might still qualify for pre-tax catch-up at one employer
Conversely, a participant earning over the threshold at a single employer is fully subject to the Roth requirement
2. If a Plan Does Not Offer Roth Contributions
SECURE 2.0 created an operational ripple effect:
If a plan does not offer a Roth feature and has participants subject to the rule:
The plan must add Roth capability, or
The plan cannot allow catch-up contributions at all
This has prompted many employers to amend their plans to include Roth options.
3. Applies to Both Regular and “Super” Catch-Ups
The Roth requirement applies to:
Standard age-50+ catch-up contributions
Enhanced “super catch-up” contributions for ages 60–63 (starting in 2025)
For high earners, all catch-up dollars must be Roth, regardless of the amount.
Why This Change Matters
1. Shifts Tax Timing
The most immediate impact is a shift in taxation:
Before: Catch-up contributions could reduce current taxable income
Now (for high earners): Contributions are taxed upfront, but grow tax-free
This effectively accelerates tax revenue for the government, which was one of the drivers behind the legislation.
2. Alters Retirement Income Strategy
Participants must rethink long-term tax planning:
Roth contributions provide tax-free distributions in retirement
This can be beneficial if:
Future tax rates are higher
The participant expects significant required minimum distributions (RMDs)
However, losing the immediate tax deduction may be a disadvantage for some high earners.
3. Increases Plan Complexity
For employers and plan administrators, the change introduces new compliance challenges:
Tracking employee compensation thresholds annually
Ensuring correct tax treatment of catch-up contributions
Updating payroll systems and plan documents
Communicating changes clearly to participants
Example Scenario
Consider a 58-year-old employee in 2026:
Salary: $175,000 in 2025 (prior year)
Eligible for catch-up contributions
Under SECURE 2.0:
All catch-up contributions must be made as Roth
The participant cannot elect pre-tax treatment for these amounts
If the catch-up limit is $8,000, the full $8,000:
Is included in taxable income today
Grows tax-free and can be withdrawn tax-free in retirement (subject to Roth rules)
Planning Considerations for Participants
1. Evaluate Tax Bracket Strategy
Participants should consider:
Current vs. expected future tax rates
Whether paying tax today (Roth) is advantageous
In some cases, Roth catch-up contributions may align well with long-term tax diversification goals.
2. Adjust Cash Flow
Because Roth contributions are after-tax:
Take-home pay will be lower than with pre-tax contributions
Participants may need to revisit budgeting or savings goals
3. Coordinate with Other Retirement Accounts
High earners may want to:
Balance pre-tax and Roth savings across accounts
Consider IRA strategies, if eligible
Monitor overall tax exposure in retirement
Considerations for Plan Sponsors
1. Ensure Roth Capability
If not already in place, plans may need to:
Add a Roth contribution feature (which we can help with)
2. Update Payroll and Systems
Employers must:
Track prior-year wages accurately (and plans at Evergreen are already having this track during our annual compliance testing)
Automatically apply Roth treatment for eligible participants
3. Communicate with Employees
Clear communication is critical:
Many participants may not understand why their contributions are being taxed differently
Education can help employees adjust expectations and make informed decisions
4. Coordinate with Advisors and RPCs
Retirement Plan Consultants (RPCs) like us at Evergreen (sometimes called Third-party administrators (TPAs)), payroll providers, financial advisors, and recordkeepers will play a key role in:
Implementing system changes
Ensuring compliance
Supporting participant education
Interaction with Other SECURE 2.0 Changes
Roth catch-up requirements intersect with several other provisions, including:
Super catch-up contributions (ages 60–63)
Expanded Roth options in employer plans
Reduced barriers to Roth adoption across plan features
Together, these changes reflect a broader shift toward after-tax retirement savings structures.
Final Thoughts
The Roth catch-up provision under SECURE 2.0 marks a meaningful shift in retirement plan design and tax strategy for higher-income workers. While it removes some flexibility, it also creates new opportunities for tax-free retirement income.
For participants, the key is proactive planning—understanding how the rule affects take-home pay, tax exposure, and long-term savings goals. For employers, timely implementation and clear communication are essential to ensure compliance and minimize confusion.
Now that we are in 2026, both individuals and plan sponsors should take steps now to prepare for this important transition.
