Some retirement savers lose a key tax break under new IRS rule

A new IRS rule taking effect in 2026 would require high-earner catch-ups into Roth 401(k)s instead of traditional pre-tax accounts, a shift that could alter retirement tax planning. The change hinges on a 2025 earnings threshold of $150,000 for payroll tax, and it comes amid guidance circulating from Fidelity and coverage by Fox Business; official IRS language has not been published yet.

Some retirement savers lose a key tax break under new IRS rule

Key Takeaways

  • High-earner catch-ups must go to Roth 401(k)s for 2026 if 2025 payroll-tax earnings reach $150,000+.
  • 2026 401(k) limits rise to $24,500; over‑50 catch-ups rise to $8,000; ages 60–63 can reach $11,250 in some plans.
  • Affected savers lose the upfront tax deduction on traditional catch-ups; Roth earnings and qualified withdrawals would be tax-free.
  • Savers earning under $150,000 in 2025 are not affected and can continue traditional or Roth catch-ups.
  • Fidelity guidance suggests strategies like maxing regular 401(k), contributing to Roth IRA or traditional IRA (with conversions), or funding an HSA if eligible.

MarketMoodz Analysis

For investors, the rule could shift contributions toward Roth-based funding, potentially altering retirement tax projections and the after-tax value of savers’ portfolios. The move emphasizes tax diversification, as Roth accounts offer tax-free growth and withdrawals if qualified, trading an upfront deduction for long-run tax efficiency.

Historically, catch-up deductions favored traditional 401(k) funding, but SECURE 2.0 aims to broaden tax diversification and long-term revenue. The new framework could influence plan design, drive demand for Roth options within employer plans, and heighten interest in Roth conversions and HSAs as complementary strategies.

Watch for official IRS guidance that confirms eligibility, thresholds, and plan-specific mechanics. Also monitor plan sponsor communications and Fidelity’s formal guidance as the 2026 calendar and tax-year reporting unfold.
