The $150k Roth Mandate: Navigating the 2026 PEO Retirement Squeeze

Starting January 1, 2026, a new rule takes effect: any employee who earned more than $150,000 in FICA wages in the previous year must make their age-50+ catch-up contributions on a Roth (after-tax) basis.

For PEOs managing hundreds of distinct client groups, this isn't just a tax change—it’s an operational and relationship risk.

The "No Roth, No Catch-Up" Risk

The danger is binary. If a PEO master plan does not currently offer a Roth contribution feature, any employee earning over $150k is legally barred from making any catch-up contributions in 2026.

In the PEO space, your "high-earner" population usually includes the business owners and C-suite executives who made the decision to hire you. If they find out in January 2026 that they can't maximize their retirement savings because of a plan limitation, the "PEO value prop" takes a massive hit.

Three Friction Points for PEO Leaders

1. The FICA Wage Audit: You must track 2025 FICA wages across all co-employed entities to identify who hits the $150k threshold. This requires seamless integration between payroll and your recordkeeper—a common failure point in legacy PEO tech stacks.
2. The "Deemed Roth" Election: The IRS has provided some flexibility through "deemed Roth" elections, but this requires specific plan amendments that must be adopted by December 31, 2026.
3. Communication Gaps: Small business owners are notoriously late to retirement compliance. If you aren't sending targeted communications to the "High-Earner" segment now, you’ll be handling the fallout during 2026 enrollment.

The Strategy: Leading with Complexity

The 2026 Roth mandate is an opportunity to prove why a PEO is better than a standalone plan. While a small business owner would have to navigate these IRS and DOL rules alone, the PEO does the heavy lifting.

Your Q2 Playbook:

• Audit for Roth Functionality: Ensure every plan under your master umbrella has Roth enabled.
• Update Payroll Logic: Automate the "catch-up switch" so that when a $150k+ earner hits their standard limit, the system automatically routes catch-ups to the Roth bucket.

Educate Early: Frame this as a "SECURE 2.0 Audit" you are performing for your clients to protect their most valuable talent.
