Required Roth Catch-Up Contributions for 2026

Why It Matters

High‑earning workers must shift additional retirement savings to after‑tax Roth accounts, reshaping tax planning and employer plan design. The delayed compliance window creates a narrow planning horizon for contributions in 2026.

Key Takeaways

• Roth catch‑up applies to employees earning >$145k FICA wages
• Transition period delays mandatory Roth catch‑up until 2026
• Employers must offer Roth 401(k) for catch‑up eligibility
• Super catch‑up increased to $11,250, also requires Roth
• Alternative pre‑tax options include FSA and HSA contributions

Pulse Analysis

The Secure 2.0 Act’s Roth catch‑up provision represents one of the most consequential changes to retirement‑plan tax treatment in recent years. By tying the requirement to a $145,000 FICA‑wage threshold—adjusted for inflation—the law forces high‑income earners to allocate their catch‑up dollars to after‑tax Roth accounts. This shift not only alters the immediate tax liability of contributors but also influences the long‑term growth trajectory of retirement balances, as qualified Roth withdrawals are tax‑free. The two‑year transition period, ending December 31 2025, was designed to give plan sponsors a runway to implement Roth 401(k) options and to establish the administrative infrastructure needed to track prior‑year wages.

For employers, the new rule triggers several operational imperatives. Plans must now provide a designated Roth contribution lane for catch‑up dollars, and many will adopt a deemed Roth catch‑up election to automate compliance. Failure to offer a Roth 401(k) option could effectively block eligible participants from making catch‑up contributions, pushing them toward traditional or Roth IRAs instead. Employees also have alternative pre‑tax avenues, such as flexible spending accounts (FSAs) and health savings accounts (HSAs), which can reduce taxable wages without invoking the Roth requirement. Notably, the “super” catch‑up increase to $11,250 for those approaching age 60 adds another layer of planning complexity, as the larger amount must also be Roth‑designated when the wage threshold applies.

Advisors and CPAs play a pivotal role in navigating this landscape. They must alert high‑earning clients to the impending Roth catch‑up mandate, evaluate whether their employers have adopted deemed elections, and model the tax impact of Roth versus pre‑tax contributions. Early coordination can prevent missed contribution windows and ensure that clients maximize their retirement savings while staying compliant. As the final regulations take effect after 2026, firms that proactively adjust plan designs and educate participants will gain a competitive edge in talent retention and financial‑wellness offerings.
