Roth Catch-Up Rule Effective 2026

Effective: January 1, 2026
Originally passed under the SECURE 2.0 Act of 2022, the long-delayed Roth-only catch-up contribution rule takes effect January 1, 2026.
Employees age 50 and older who earned more than $145,000 in Social Security wages (Box 3) from their employer in the prior year must make any catch-up contributions on a Roth (after-tax) basis. Those below the threshold may continue to make traditional pre-tax catch-ups.
What Employers Should Know:
The rule applies to 401(k), 403(b), and 457(b) plans.
If your plan does not offer a Roth option, high earners will be unable to make catch-up contributions in 2026.
isolved is fully prepared for this update beginning January 1, 2026; no action is required from clients at this time.
Employers should still confirm their plan allows Roth contributions and communicate the upcoming change to employees who make catch-ups.
