As the SECURE Act 2.0 continues to phase in, one of the biggest changes for 2026 affects how catch-up retirement contributions are treated for higher-income savers. This isn’t just a technical rule change — it can influence tax planning, retirement income strategy, and how you think about your savings in the years leading up to retirement.
What’s Changing in 2026?
Starting January 1, 2026, the IRS requires that certain “catch-up” contributions to workplace retirement plans — such as 401(k)s, 403(b)s, and governmental 457(b) plans — must be made on a Roth (after-tax) basis for participants who meet specific income criteria. This requirement comes from final IRS guidance implementing the SECURE Act 2.0 provision on Roth catch-up contributions.
Here’s what that means:
- If you are age 50 or older and your FICA wages from the employer sponsoring your plan exceeded a defined threshold in the prior year, then any catch-up contributions you make in 2026 must go into the Roth portion of your retirement plan — after-tax dollars.
- The income threshold used to determine who is subject to the rule is indexed but applies generally to individuals with prior-year FICA wages above approximately $145,000–$150,000.
- If your income falls below that threshold, you can still make catch-up contributions on either a pre-tax or Roth basis, depending on your plan options.
This change takes effect with the 2026 plan year, and the IRS has provided guidance to help plan sponsors and administrators implement the requirement.
Why This Matters to You
This change doesn’t stop you from saving more — it shifts how those extra “catch-up” dollars are taxed:
- Traditional pre-tax catch-up contributions reduce your current taxable income.
- Roth (after-tax) catch-up contributions do not reduce current taxable income, but qualified withdrawals in retirement are tax-free.
For higher-income savers, this means:
- You may pay more tax today on additional contributions if you’re subject to the Roth catch-up rule.
- In exchange, future growth and qualified withdrawals can be tax-free, enhancing retirement income planning.
The Roth requirement only applies to the catch-up portion of your contributions — not your regular deferrals.
What to Consider in Your Planning
Here are some practical points to think about as you prepare for 2026:
- Check your plan’s Roth availability.
Not all employer plans currently offer a Roth contribution option. If yours doesn’t, you may lose the ability to make catch-up contributions unless the plan is amended. - Review your income projections.
Understanding whether your earnings will exceed the Roth catch-up threshold can help you plan your contributions and tax strategy for 2026. - Coordinate with broader tax planning.
A Roth designation may affect your current-year tax bill. Coordinate with your tax advisor to balance current tax liability with future tax-free retirement income.
Bottom Line
The 2026 Roth catch-up change represents a meaningful shift in retirement savings strategy for higher-income participants who want to take full advantage of catch-up contributions. While it may increase current taxable income, it also expands opportunities for tax-free growth and retirement income. Planning ahead will help you make informed decisions that align with your broader financial goals.
