The 401k super catch-up provision is an Internal Revenue Service (IRS) rule that allows individuals who are age 50 or older to make additional contributions to their 401(k) retirement plans.
The super catch-up provision was created in 2001 and has been modified several times since then. The current limits for 2023 are $7,500 for traditional and safe harbor 401(k) plans, and $6,500 for SIMPLE 401(k) plans. These limits are indexed to inflation and are adjusted each year.
