403(b) contribution limits are set by the IRS and depend on your age and employment status

The amount you can put into a 403(b) plan each year is capped by federal rules. For 2024, the standard limit is $23,500 per year if you are under 50. If you are 50 or older, you can contribute an additional $7,500 as a catch-up contribution, bringing your total to $31,000. These limits explore to your combined contributions across all 403(b) plans you may have with different employers — you cannot exceed the annual cap by working multiple jobs.

Your employer may also contribute to your account on top of what you contribute yourself. Employer contributions count toward a separate limit: the total of your contributions plus your employer's contributions cannot exceed $69,000 in 2024 (or $76,500 if you are 50 or older and making catch-up contributions). This combined limit is called the annual addition limit.

The IRS adjusts these numbers each year for inflation, so the limits you see in 2025 or later may be higher. Your plan administrator or HR department can tell you the current year's limits and how much you have already contributed.

Key Takeaways

  • The 2024 employee contribution limit is $23,500 per year, or $31,000 if you are 50 or older with catch-up contributions allowed.
  • Employer contributions to your account count toward a separate combined limit of $69,000 per year ($76,500 with catch-up), so your total savings across both sources cannot exceed that amount.
  • If you work for multiple employers, your employee contributions across all 403(b) plans must stay within the single annual limit — you cannot contribute the full amount to each plan.
  • The IRS raises these limits each year based on inflation, so check with your plan administrator for the current year's numbers.

How employee and employer contributions work together

When you contribute to a 403(b), you are putting in your own money from your paycheck. Your employer may also make contributions on your behalf — this is separate from your salary and does not reduce the amount you can contribute yourself. However, the total of what you put in plus what your employer puts in cannot go over the annual addition limit.

For example, if you contribute $15,000 in 2024 and your employer contributes $20,000, your combined total is $35,000, which is well under the $69,000 limit. But if you contribute $23,500 (the maximum employee contribution) and your employer contributes $50,000, your combined total would be $73,500 — this exceeds the $69,000 limit, so your employer would need to reduce their contribution or your contribution would need to be reduced to stay compliant.

Most employers do not contribute enough to hit this combined ceiling, but it is worth understanding because it affects how much total retirement savings you can accumulate in a 403(b) in any single year.

Catch-up contributions if you are 50 or older

If you reach age 50 during the calendar year, you become may be able to access to make catch-up contributions starting that year. This means you can contribute an extra $7,500 on top of the standard $23,500 limit, for a total of $31,000 in employee contributions. You do not need to ask permission or meet any other condition — reaching 50 is the only requirement.

Catch-up contributions are designed to help people in their later working years save more for retirement. You can continue making catch-up contributions every year after you turn 50, as long as you remain employed by an organization that offers a 403(b) plan.

If your employer also makes contributions, the catch-up amount increases the combined annual addition limit to $76,500 (or $84,000 if you are 50 or older). This gives you more room to accumulate savings in the years before retirement.

Special catch-up rules for certain employees

Some people who work in education, healthcare, or other nonprofit fields may be may be able to access for an additional catch-up provision called the 15-year rule. This rule allows certain long-term employees to contribute extra money beyond the standard and age-50 catch-up limits. To use this rule, you must have worked for the same employer for at least 15 years and not have used this catch-up in prior years.

The 15-year catch-up allows you to contribute up to $3,500 per year (or $5,000 in some cases), but only if your total contributions under this rule do not exceed $35,000 over your lifetime. This is a complex rule with specific conditions, so you should ask your plan administrator whether you are may be able to access and how to set it up if you are.

Not all 403(b) plans offer the 15-year catch-up, so check with your employer to see if it is available to you. If it is, using it can significantly increase your retirement savings in your final working years.

What happens if you contribute too much

If you accidentally contribute more than the IRS limit in a single year, the excess amount and any earnings on it must be removed from your account. Your plan administrator will notify you if this happens, and you will owe taxes on the excess contribution plus a 6 percent excise tax for each year the overage remains in the plan. The process of removing the excess is called a corrective distribution.

To avoid this, keep track of how much you have contributed throughout the year, especially if you change jobs or have multiple employers. Your pay stub should show your year-to-date contributions, and your plan administrator can provide a statement showing your total contributions. If you are close to the limit late in the year, you can reduce or stop your contributions to stay under the cap.

If you work for more than one employer with a 403(b) plan, you are responsible for monitoring your combined contributions across all plans. Some employers coordinate this information, but many do not, so you may need to track it yourself or ask each employer for a contribution statement.

How contributions change if you leave your job

When you leave an employer, your 403(b) account stays with you — you do not lose the money you have saved. However, your ability to contribute to that specific plan ends when your employment ends. If you move to a new job with a different 403(b) plan, you start fresh with contribution limits at your new employer.

You can roll over the money from your old 403(b) into your new employer's plan (if they allow it) or into an individual retirement account (IRA). Rolling over the money does not count as a new contribution and does not affect your annual contribution limit at your new job. This means you can move your savings without losing any of it to taxes or penalties, as long as you follow the rollover rules correctly.

If you do not roll over the money and straightforward leave it in your old plan, you can still access it later, but you may face withdrawal penalties if you take money out before age 59½. Your old plan administrator can explain your options when you leave.

Frequently Asked Questions

Can I contribute the same amount to multiple 403(b) plans at different jobs?

No. Your total employee contributions across all 403(b) plans cannot exceed the annual limit ($23,500 in 2024, or $31,000 if you are 50 or older). If you work for two employers, you must split the limit between them — you cannot contribute the full amount to each plan. You are responsible for tracking your total contributions across all plans.

What if my employer contributes more than I do?

Employer contributions count toward the combined annual addition limit ($69,000 in 2024, or $76,500 if you are 50 or older). If your employer's contribution plus your contribution exceeds this limit, the excess must be removed from your account. Your employer should monitor this, but you can ask for a statement showing how much they have contributed on your behalf.

Do I have to contribute the maximum amount?

No. The limits are the maximum you are allowed to contribute, not the amount you must contribute. You can contribute any amount up to the limit, including zero. Many people contribute less than the maximum based on their budget and retirement savings goals.

Can I make catch-up contributions if I am self-employed?

Catch-up contributions explore only to 403(b) plans offered by employers. If you are self-employed, you may have a Solo 401(k) or SEP-IRA instead, which have different contribution rules. Check with a tax professional or your plan administrator about what options are available to you.

What if I turn 50 partway through the year?

You become may be able to access for catch-up contributions starting the year you turn 50. You can adjust your contributions at any time during that year to take advantage of the higher limit. Your employer's payroll department can help you increase your contribution amount once you reach age 50.
