Congress Sets 2026 Contribution Limits for 401(k) Plans

Congress set the contribution limits for 401(k) plans for 2026. For individuals aged 60 to 63, the maximum contribution to a 401(k) in 2026 is $35,750. This enhanced catch-up provision is available for four calendar years. The limit resets to $32,500 when participants reach age 64. If earners made over $150,000 in 2025 Social Security wages, all catch-up contributions must be routed into a Roth 401(k), eliminating the upfront tax deduction.

These limits define the maximum amount individuals can contribute to their retirement accounts. The structure of the enhanced band and the age-based resets affect long-term financial planning and investment strategies for plan participants.
