Fidelity Investments has released detailed guidance for plan sponsors on the upcoming 2026 Roth catch-up contribution mandate, a rule that will affect a significant segment of older workers. The new requirement, part of the SECURE 2.0 Act, stipulates that employees aged 50 and older whose prior-year same-employer FICA wages exceeded $150,000 must make their catch-up contributions on a Roth (after-tax) basis. This threshold applies to contributions made in 2026, based on 2025 wages from the same employer.
The change does not reduce the amount older workers can save; rather, it alters the tax treatment. Those affected lose the immediate tax deduction on catch-up dollars but gain the benefit of tax-free qualified withdrawals in retirement. The regular 401(k) employee deferral limit for 2026 is $24,500, up from $23,500 in 2025. The age-50 catch-up limit rises to $8,000 from $7,500, while the enhanced catch-up for those aged 60-63 remains at $11,250.
Payroll Execution: The Immediate Challenge
Fidelity's guidance to plan sponsors highlights three operational paths for handling affected participants: automatically converting excess pre-tax deferrals to Roth, requiring an active Roth election, or zeroing out pre-tax catch-ups entirely. Plans that do not offer a Roth feature cannot accept catch-up contributions from affected workers. The choice of approach can have significant consequences, particularly for late-year savers who may inadvertently hit the regular limit and miss out on the full catch-up allowance.
The wage test is narrowly defined: it uses only prior-year wages from the plan sponsor, not household income or other sources. This means a worker with substantial investment income or a spouse's high earnings may still pass the test if their own sponsor wages are below $150,000.
Record Balances and Industry Context
The new rule lands at a time when retirement account balances are at record highs. Fidelity's latest retirement analysis, covering more than 55 million accounts, shows average 401(k) balances reached $155,800 in Q2 2026, up 13% year-over-year. 403(b) balances averaged $145,000 (up 16%), and IRAs averaged $144,523 (up 10%). Sharon Brovelli, president of workplace investing at Fidelity, noted that "workers continue to prioritize their financial future."
While Fidelity is privately held, the closest publicly traded comparison is Charles Schwab Corporation (NYSE: SCHW), which also serves as a major retirement plan recordkeeper. Schwab reported 5.91 million workplace participant accounts and $13.41 trillion in client assets as of August. The company's shares closed Friday at $105.25, up 0.59%, with volume about 2.1 times the three-session average. Premarket trading on Monday showed little change.
Analyst Views and Market Implications
Analysts remain broadly positive on Schwab. Barclays' Benjamin Budish maintained a Buy rating with a $125 target on September 16. DBS' Manyi Lu also maintained Buy with a $120 target on August 6. Compass Point's Ed Engel initiated coverage with a Buy and $135 target on August 3. However, these targets reflect the broader platform's strength, including August core net new assets of $64.8 billion, up 46% year-over-year. The Roth rule alone does not justify these forecasts.
The durable investor question is retention: clean payroll handling can protect employer relationships, but neither Fidelity nor Schwab has disclosed incremental revenue directly tied to the rule. Risks include affected workers stopping at the regular $24,500 limit instead of accepting Roth treatment, operational errors triggering corrections, or a smooth rollout producing no measurable lift for recordkeepers.
Plan sponsors must ensure their payroll systems are ready well before each plan's final 2026 payroll. The IRS requires catch-up deferrals to be completed by year-end, leaving little room to correct an incorrect election afterward. As the January 1, 2026 effective date approaches, employers and recordkeepers alike face the immediate test of execution.
