Key Insights

Contribution limits define the maximum annual amount individuals can deposit into an I401k plan, set by the IRS each year with updates effective January 1. For 2025, the threshold is $23,000 per employee, with an additional $7,500 catch-up contribution if age 50 or older, raising the total limit to $30,500.
