IRS Issues Final Regs on Roth Mandatory Catch-ups for High Earners
The IRS has finalized regulations under SECURE 2.0 that will impact how certain participants save for retirement. Under this change, employees with prior-year FICA wages above $150,000 will no longer be able to make pre-tax catch-up contributions to their 401(k), 403(b), or 457(b) plans. Instead, those contributions will have to be made on a Roth, or after-tax, basis. The rule takes effect on Jan. 1, 2026. According to the IRS, the regulations “generally apply to contributions in taxable years,” beginning in 2027. However, it also notes that “the final regulations also permit plans to implement the Roth catch-up requirement for taxable years beginning before 2027 using a reasonable, good faith interpretation of statutory provisions.” The administrative transition period (under Notice 2025-67), which generally ends on Dec. 31, 2025, remains unchanged by the final regulations.
