A major SECURE 2.0 provision is now in effect for 2026: if you earned more than $150,000 in 2025 and want to make catch-up contributions to your 401(k), those contributions must now be made on a Roth (after-tax) basis. This marks a significant shift in retirement planning for higher-income workers age 50 and older.
What Changed in 2026
Previously, workers age 50 and over could choose whether to direct their catch-up contributions to traditional pre-tax accounts or Roth accounts. That choice no longer exists for higher earners.
Under the new rule, if your prior-year wages exceeded $150,000, any catch-up contributions to your 401(k), 403(b), or governmental 457 plan must be designated as Roth contributions. The $150,000 threshold is not indexed for inflation, meaning more workers will be affected over time as wages increase.
Workers earning $150,000 or less in the prior year retain the flexibility to direct catch-up contributions to either pre-tax or Roth accounts.
2026 Contribution Limits
The IRS has increased retirement contribution limits for 2026:
- Standard 401(k) contribution: $24,500 (up from $23,500)
- Catch-up contribution (age 50+): $8,000 (up from $7,500)
- Super catch-up (ages 60-63): $11,250
- Total for workers 50-59 or 64+: $32,500
- Total for workers 60-63: $35,750
For affected high earners, the $8,000 standard catch-up (or $11,250 super catch-up) must go into a Roth account. Your base $24,500 contribution can still be directed to either pre-tax or Roth as you prefer.
Why This Matters for Your Tax Strategy
The mandatory Roth requirement changes the tax calculus for many retirement savers:
Immediate impact: You'll pay taxes now on catch-up contributions rather than deferring them. For someone in the 32% federal bracket contributing the full $8,000 catch-up, that's approximately $2,560 more in current-year taxes.
Long-term benefit: Roth contributions grow tax-free and qualified withdrawals in retirement are completely tax-free. If tax rates rise or you remain in a high bracket during retirement, Roth contributions may prove advantageous.
Tax diversification: Having both pre-tax and Roth retirement assets gives you flexibility in managing taxable income during retirement, potentially helping control Medicare premium surcharges and Social Security taxation.
What You Should Do Now
Verify your plan offers Roth. Not all employer plans have a Roth option. If yours doesn't, you may lose the ability to make catch-up contributions entirely until your employer adds this feature. Check with your HR department.
Review your payroll elections. Ensure your contribution elections are set correctly for 2026. Some plans may require you to actively designate Roth catch-up contributions.
Reassess your overall strategy. Consider whether to shift some of your base contributions to Roth as well, creating a more balanced retirement portfolio between pre-tax and after-tax accounts.
Plan for the tax hit. Budget for the additional current-year taxes on your now-mandatory Roth catch-up contributions.
Who Is Not Affected
This rule applies only to employer-sponsored plans. IRA catch-up contributions are not subject to the mandatory Roth requirement regardless of income. You can still make traditional or Roth IRA contributions (within income limits) according to your preference.
Additionally, workers who earned $150,000 or less in the prior tax year maintain full flexibility over how they direct catch-up contributions.
The Bottom Line
The mandatory Roth catch-up rule represents one of the most significant retirement plan changes in recent years for higher-income workers. While losing the pre-tax option may feel restrictive, building a larger Roth balance can provide valuable tax flexibility in retirement. Review your current contribution elections and consult with a financial advisor to optimize your strategy under the new rules.
