Retirement catch-up contribution IRS rule change, effective Jan. 1, 2026
November 3, 2025
Employees age 50 or older, can make extra “catch-up” contributions to their retirement plans. Starting Jan. 1, 2026, catch-up contributions for employees earning more than $145,000 in wages (Box 3 on the 2025 W-2) must be made as Roth (after-tax) contributions under new IRS rules.
Employees earning more than $145,000 in 2025:
- Age-based catch-up contributions in 2026 must be Roth (after-tax).
- Taxes will be taken out prior to contributions going into the plan.
- Contributions grow tax-deferred, and qualified withdrawals (once the account has been open for 5 years and other distribution rules are met) are tax-free, including earnings.
Employees earning $145,000 or less:
- Catch-up contributions can be made via pre-tax or Roth, depending on preference.
