403(b) contribution limits
In 2025, you may contribute up to $23,500. The contribution limits rise to $31,000 if you're 50 or older. Adults aged 60 to 63 may contribute up to $34,750 in 2025. These limits are the same as the contribution limits for a 401(k). Note that if your employer offers access to both a 401(k) and a 403(b) plan in the same year, the limit applies to your total contributions to both accounts.
You may be eligible to contribute up to $3,000 additional past standard contribution limits in a given year if you've worked for your employer for at least 15 years. There's a $15,000 lifetime maximum on this, so if you’re in this situation, you’ll want to keep close track of the amount of extra contributions you make.
