Max 401k Ira Contribution 2024. Workers who contribute to a 401 (k), 403 (b), most 457 plans and the federal government’s thrift savings plan can contribute up to $23,000 in 2024, a $500 increase. I estimate it will go up to $16,500 in 2025.

For individual retirement accounts, or iras—both roth and traditional types—2024 contributions will max out at $7,000, up from $6,500 in 2023. In 2024, those amounts are $7,000 and $8,000, respectively.
