Annual 401k Contribution Limit 2024. In 2025, the irs allows you to contribute up to $23,500 to your 401 (k) plan, up from $23,000 in 2024. So, if you were exercising this option in 2024, you'd only be able to roll over up to $7,000, which is the 2024 limit for people younger than 50.
The irs revisits these numbers annually and, if necessary, adjusts. The 401(k) contribution limit is the maximum amount an individual can contribute to their 401(k) retirement account in a calendar year without facing tax penalties.
