401k 2025 Maximum Contribution. In 2025, employers and employees together can. For those with a 401(k), 403(b), or 457 plan through an employer, your new maximum contribution limit will go up to $23,000 in 2025.
For 2025, the 401 (k) limit for employee salary deferrals is $23,000, which is above the 2025 401 (k) limit of $22,500. If you contribute, say, $23,000 toward your 401 (k) in 2025 and your employer adds $5,000, you’re still within the irs limits.
