What the SECURE 2.0 Roth mandate actually requires
Starting January 1, 2026, employees who earned more than $145,000 in the prior year and who participate in a 401(k), 403(b), or governmental 457(b) plan must make their catch-up contributions on a Roth basis — meaning after-tax dollars, not pre-tax.
This applies to the standard catch-up contribution limit of $7,500 for workers age 50 and older, and to the new 'super catch-up' limit of $11,250 for workers age 60, 61, 62, or 63 introduced by SECURE 2.0. If your income is at or below $145,000, you can still choose whether to make catch-up contributions pre-tax or Roth.
The $145,000 threshold is based on your prior-year W-2 wages from the same employer. It is not adjusted for inflation, so more workers will be affected over time as wages rise.
The 2026 contribution limits at a glance
The 401(k) employee contribution limit for 2026 is $24,500, up from $23,500 in 2025. The IRA contribution limit rose to $7,500, up from $7,000. For workers age 50 and older, the standard catch-up is $7,500 additional, bringing the 401(k) total to $32,000. For workers age 60 through 63, the super catch-up is $11,250 additional, for a total of $35,750.
If you are subject to the Roth mandate, the catch-up portion of your contributions will not reduce your taxable income this year. Instead, those dollars grow tax-free and qualified withdrawals in retirement are tax-free.
Is the Roth mandate good or bad for you?
The answer depends on your tax situation. If you expect to be in a higher tax bracket in retirement than you are today, Roth contributions are better — you pay tax now at a lower rate and withdraw tax-free later. If you expect to be in a lower bracket in retirement, pre-tax contributions are generally better.
For high earners who are close to retirement, losing the pre-tax deduction on catch-up contributions means a higher tax bill today. However, Roth accounts have no required minimum distributions during the owner's lifetime, which can be a significant planning advantage for people who do not need to draw down their retirement accounts immediately at 73.
Your employer's payroll system must be updated to handle Roth catch-up contributions separately. If your employer's plan does not yet support Roth catch-ups, you may not be able to make catch-up contributions at all in 2026 — a situation worth checking with your HR or benefits department before year-end.
