A long-delayed SECURE 2.0 Act provision finally took effect this year, and it changes how older, higher-income workers fund the final stretch of their careers. Beginning January 1, 2026, employees age 50 and over whose prior-year FICA wages from their plan sponsor exceeded $150,000 can no longer make pre-tax catch-up contributions to their employer-sponsored retirement plan. Those catch-ups must now go into a Roth account, with after-tax dollars.
For workers used to maximizing every pre-tax dollar, this is a meaningful shift. Here is what changed, who is affected, and how to plan around it.
The 2026 Contribution Limits
The IRS raised the standard limits for the new year. The 401(k) elective deferral cap climbed to $24,500, up from $23,500 in 2025, and the IRA contribution limit rose to $7,500 from $7,000. The IRA catch-up for those 50 and older moved to $1,100.
A separate SECURE 2.0 enhancement preserves a higher "super catch-up" of $11,250 for employees ages 60 through 63, replacing the standard $8,000 catch-up during that narrow window.
Who the Roth Mandate Applies To
Three conditions must all be true for the new Roth catch-up rule to trigger:
- You are age 50 or older during the plan year.
- Your FICA-taxable wages from the plan-sponsoring employer in the prior calendar year (2025 for the 2026 plan year) exceeded $150,000.
- You want to make catch-up contributions to a workplace plan such as a 401(k), 403(b), or governmental 457(b).
Notably, the test is based on wages from the specific employer sponsoring the plan, not total household income. Self-employment income does not count toward the threshold, and the $150,000 figure will be indexed for inflation in later years. IRA catch-ups are not affected.
What Happens If Your Plan Lacks a Roth Option
If your employer's plan does not offer a Roth feature, you cannot make catch-up contributions at all for the year. Industry surveys conducted ahead of the rule's effective date suggested most large plans had added Roth features in time, but smaller employers were the most likely to fall short. Workers in that situation should ask HR whether a Roth option has been added or is planned.
The Trade-Off for Affected Workers
Losing the upfront deduction stings, especially for taxpayers in the 32% or 35% federal brackets. But the Roth catch-up grows tax-free and is not subject to required minimum distributions during the original owner's lifetime under current rules. For workers who expect to be in a similar or higher bracket in retirement — which is increasingly common given current federal deficits and the scheduled 2026 expiration of several Tax Cuts and Jobs Act provisions — the Roth treatment may be a wash or even an advantage over time.
Practical Planning Steps
- Confirm your status early. Check your 2025 W-2 box 3 (Social Security wages) against the $150,000 threshold to know whether the rule applies to your 2026 catch-ups.
- Adjust withholding. Roth contributions do not lower taxable income, so workers shifting from pre-tax catch-ups should expect a modestly higher tax bill and may want to revisit withholding or estimated payments.
- Coordinate with broader diversification. Tax diversification — holding a mix of pre-tax, Roth, and taxable assets — gives retirees more flexibility to manage their tax bracket year by year. The forced Roth treatment, while inconvenient now, can strengthen that mix.
- Revisit IRA and HSA contributions. Because IRAs are unaffected, high earners may want to ensure they are still funding traditional or backdoor Roth IRAs and maxing out HSAs where eligible.
The Roth catch-up mandate will not change anyone's retirement on its own. But for older high-earning workers in their peak savings years, it reshapes the math on tax planning and reinforces the value of building tax diversification long before withdrawals begin.
