A significant retirement planning change took effect on January 1, 2026, and it directly impacts workers over 50 who earn more than $150,000 annually. Under the SECURE 2.0 Act, these high earners must now make their catch-up contributions exclusively to Roth accounts—a shift that requires careful planning but may offer substantial long-term benefits.
What Changed in 2026
Previously, workers aged 50 and older could choose whether to make catch-up contributions on a pre-tax or Roth (after-tax) basis. Starting this year, participants who earned more than $150,000 in FICA wages during 2025 must direct all catch-up contributions to Roth accounts within their 401(k), 403(b), or governmental 457(b) plans.
The income threshold of $150,000 applies specifically to wages from the employer sponsoring your retirement plan—not your total household income. This threshold is also indexed for inflation and may increase in future years.
2026 Contribution Limits at a Glance
The IRS has increased contribution limits for 2026:
- Standard 401(k) limit: $24,500 (up from $23,500 in 2025)
- Standard catch-up contribution (age 50+): $8,000
- Super catch-up (ages 60-63): $11,250
- Total potential contribution (age 50+): $32,500
- Total potential contribution (ages 60-63): $35,750
Workers earning under $150,000 can still choose between pre-tax and Roth catch-up contributions. The mandatory Roth requirement only affects those above the income threshold.
Why This Matters for Your Retirement Strategy
While the mandatory Roth catch-up rule may feel restrictive, it offers potential advantages:
Tax-free growth: Roth contributions grow tax-free, and qualified withdrawals in retirement are also tax-free. For high earners who expect to remain in elevated tax brackets during retirement, this can be particularly valuable.
No required minimum distributions: Unlike traditional pre-tax accounts, Roth 401(k) accounts are no longer subject to RMDs during the owner's lifetime (another SECURE 2.0 change), providing more flexibility in retirement income planning.
Tax diversification: Having both pre-tax and Roth retirement assets gives you options for managing your tax liability in retirement.
What You Should Do Now
1. Verify your plan offers Roth contributions. If your employer's plan doesn't include a Roth option, you won't be able to make catch-up contributions at all in 2026. The IRS has indicated that employers should be operating in "reasonable, good faith" compliance this year, with formal requirements taking effect in 2027.
2. Review your 2025 earnings. If your FICA wages from your current employer exceeded $150,000 last year, the Roth catch-up requirement applies to you.
3. Adjust your payroll elections. Ensure your catch-up contributions are directed to your Roth account to avoid compliance issues.
4. Consider the broader picture. With IRA contribution limits rising to $7,500 (plus a $1,100 catch-up for those 50+) and Social Security benefits increasing by 2.8% in 2026, this is an opportune time to review your entire retirement strategy.
The Bottom Line
The SECURE 2.0 Act's Roth catch-up requirement represents a meaningful shift in retirement planning for high earners. While it removes some flexibility, it also nudges savers toward building tax-free retirement income—a strategy many financial advisors have long recommended. Take time this year to understand how these changes affect your situation and adjust your contributions accordingly.
