The Final Roth Catch-Up Regulations: What Plan Sponsors Should Do Before 2026

The IRS and Treasury Department have finalized their guidance on Roth catch-up contributions, and the changes are set to reshape how retirement plans operate in 2026 and beyond. These updates—stemming from the SECURE 2.0 Act—carry important implications for both plan sponsors and employees, especially high earners approaching retirement.

At Talk Retirement, we help plan sponsors stay ahead of evolving regulations, ensuring compliance while keeping employee benefits competitive. In this article, we’ll unpack the new rules, explore their impact, and outline what sponsors should do to prepare before the 2026 deadline.

What Are Catch-Up Contributions?

Catch-up contributions allow employees aged 50 and older to contribute extra funds to their 401(k), 403(b), or similar retirement plan. For 2025, the standard deferral limit is $23,000, with an additional $7,500 allowed for catch-up contributions. These contributions help older workers accelerate savings as they approach retirement.

Historically, participants could choose to make catch-up contributions as pre-tax (traditional) or after-tax (Roth). The new IRS rules change that flexibility for higher earners.

What Do the Final Roth Catch-Up Regulations Require?

Starting in 2026 (after a two-year implementation delay), the following rules will apply:

1. Mandatory Roth Treatment for High Earners

   • If an employee earned more than $145,000 in the prior year (indexed for inflation), their catch-up contributions must be made on a Roth basis.

   • This means no pre-tax catch-up contributions for high earners—taxes are paid upfront, but qualified withdrawals in retirement are tax-free.

2. Roth Capability Required

   • All plans that permit catch-up contributions must also allow for Roth contributions.

   • Sponsors without Roth features in their plan documents will need amendments.

3. Payroll Adjustments

   • Employers must coordinate with payroll providers to track income levels and route catch-up contributions correctly.

Why Did the IRS Delay Implementation Until 2026?

Originally set to take effect in 2024, the Roth catch-up mandate was delayed after significant pushback from employers, recordkeepers, and payroll providers who said the timeline was too aggressive.

The two-year transition gives sponsors time to:

• Amend plan documents

• Upgrade payroll systems

• Educate employees about the new requirements

This delay is a window of opportunity—sponsors who act early will avoid compliance headaches later.

Who Is Impacted by the Roth Catch-Up Rule?

• Employees 50+ earning over $145,000: Must make Roth catch-up contributions only.

• Employees earning under $145,000: Retain the choice between Roth and traditional catch-up contributions.

• Plan sponsors: Must update documents, systems, and communication strategies.

This change is most significant for high earners who previously used pre-tax catch-up contributions to reduce taxable income.

Pros and Cons for Participants

Advantages of Roth Catch-Up Contributions

• Tax-free withdrawals in retirement

• Greater tax diversification between Roth and traditional accounts

• Protection against potentially higher future tax rates

Disadvantages

• No immediate tax deduction on contributions

• Reduced ability to lower taxable income in the present year

• More complexity in financial planning

For many employees, the shift may be less about opportunity and more about adjusting expectations.

What Plan Sponsors Must Do Before 2026

At Talk Retirement, we recommend that plan sponsors take these steps now to avoid last-minute compliance stress:

1. Add Roth Features if Not Already Available

If your plan does not currently offer a Roth option, it must be added before 2026. This requires plan amendments and communication with your recordkeeper.

2. Coordinate With Payroll and Recordkeepers

Payroll systems need to distinguish between standard deferrals, traditional catch-up contributions, and Roth catch-up contributions. Work closely with providers to ensure smooth processing.

3. Update Plan Documents and Procedures

Formal plan amendments may be necessary. Document operational changes and keep clear compliance records.

4. Communicate With Employees

High earners may be surprised to learn they can no longer reduce taxable income through pre-tax catch-ups. Sponsors should proactively educate employees on the change, its tax impact, and the benefits of Roth savings.

5. Consult Advisors and Legal Counsel

Regulatory changes are complex. Consulting with experts—like those at Talk Retirement—helps ensure compliance while maximizing the value of retirement benefits.

Strategic Opportunities for Sponsors

While compliance is the immediate concern, sponsors can also use this change to enhance their retirement plans:

• Encourage tax diversification: Educate employees on the benefits of having both Roth and traditional balances.

• Improve employee engagement: Use this regulatory update as a touchpoint for financial wellness communications.

• Strengthen recruitment and retention: Demonstrating proactive retirement planning can make your organization more attractive to top talent.

The Bigger Picture: SECURE 2.0 and Beyond

The Roth catch-up regulation is just one piece of the larger SECURE 2.0 Act, which continues to reshape retirement policy. Other provisions include expanded eligibility for part-time employees, new required minimum distribution (RMD) ages, and student loan payment matching.

For sponsors, this means constant adaptation. The organizations that thrive will be those that take a proactive, informed approach to compliance and employee engagement.

Final Thoughts

The final Roth catch-up regulations represent one of the most significant retirement policy shifts in recent years. High earners will lose the ability to make pre-tax catch-up contributions, and sponsors must ensure Roth features are available in their plans by 2026.

This change creates challenges—but also opportunities. By acting early, sponsors can avoid compliance pitfalls and use this moment to strengthen their retirement programs.

At Talk Retirement, we guide plan sponsors through regulatory transitions with clarity and confidence. If your organization is preparing for the Roth catch-up rules, now is the time to act.
