One of the most significant SECURE 2.0 provisions took effect this year, and it directly impacts workers age 50 and older who earned more than $150,000 in the prior year. If you fall into this category, your catch-up contributions must now go into a Roth account rather than a traditional pre-tax account.
Here's what this change means for your retirement strategy and how to adapt.
The New Mandatory Roth Rule Explained
Starting in 2026, if you earned over $150,000 in FICA wages in the previous calendar year, any catch-up contributions you make to your 401(k), 403(b), or governmental 457(b) plan must be designated as Roth contributions. These are made with after-tax dollars, meaning you pay taxes now but enjoy tax-free withdrawals in retirement.
The $150,000 threshold is based on your wages from the specific employer sponsoring the plan, not your total household income. This distinction matters if you work for multiple employers or if your spouse has a separate retirement plan.
2026 Contribution Limits at a Glance
The IRS has set the following limits for 2026:
- Standard 401(k) contribution: $24,500
- Catch-up contribution (age 50+): $8,000
- Total maximum (age 50+): $32,500
- Super catch-up (ages 60-63): $11,250
- Total maximum (ages 60-63): $35,750
For high earners affected by the mandatory Roth rule, that $8,000 catch-up (or $11,250 for those 60-63) must now go into the Roth portion of your retirement account.
What If Your Employer Doesn't Offer a Roth Option?
This is a critical consideration. If your employer's retirement plan does not offer a Roth contribution option and you meet the $150,000 threshold, you will not be permitted to make catch-up contributions at all under that plan.
Many employers have added Roth options in recent years specifically to accommodate this rule. Check with your HR department or plan administrator to confirm your plan includes a designated Roth account.
The Tax Trade-Off
For workers accustomed to the immediate tax deduction from pre-tax catch-up contributions, this change requires a mindset shift. With Roth contributions, you pay taxes on the money now, but all future growth and withdrawals are completely tax-free in retirement, assuming you meet the holding requirements.
Consider your current tax bracket versus your expected tax bracket in retirement. If you expect to be in a similar or higher bracket later, paying taxes now through Roth contributions may actually work in your favor.
Practical Steps to Take
1. Verify your plan offers a Roth option. Contact your plan administrator immediately if you're unsure.
2. Review your 2025 W-2. Your eligibility for 2026 is based on prior-year wages. If you earned over $150,000 in FICA wages in 2025, you're subject to the mandatory Roth rule.
3. Update your contribution elections. Ensure your catch-up contributions are directed to the Roth account to avoid compliance issues.
4. Consider increasing contributions. Workers ages 60-63 can now contribute up to $35,750 total in 2026 through the enhanced "super catch-up" provision, also part of SECURE 2.0.
The Silver Lining
While losing the immediate tax deduction may feel painful, building a larger Roth balance provides valuable flexibility in retirement. Roth withdrawals don't count toward the income thresholds that trigger Medicare premium surcharges, and they provide tax-free income regardless of future tax rate changes.
For high earners approaching retirement, this forced Roth accumulation could prove beneficial in the long run.
