How Much Can Your Employer Put Into Your 403(b) Plan Each Year

Yes, there is a limit, and it applies to the total your employer contributes on your behalf

Your employer cannot put unlimited money into your 403(b) plan. The IRS sets an annual ceiling on how much can go in each year, and this limit includes both what you contribute (through payroll deductions) and what your employer contributes. For 2024, that total limit is $23,500 if you are under age 50, or $31,000 if you are 50 or older (the extra $7,500 is called a catch-up contribution). These numbers change each year, so you should check the current limit when you review your plan.

The limit exists to prevent high-income employees from using 403(b) plans as a tax shelter. Your employer's contributions count toward this ceiling just like your own do. If your employer puts in $10,000 and you contribute $10,000, you have used $20,000 of your $23,500 annual limit. Once you hit the ceiling, no more money can go into the plan that year, whether it comes from your paycheck or your employer's pocket.

Key Takeaways

The annual contribution limit for 2024 is $23,500 (or $31,000 if you are age 50 or older), and this total includes both your contributions and your employer's contributions.
Your employer's contributions are counted dollar-for-dollar against this limit, so a generous employer match still uses up your available space.
If you reach the limit partway through the year, your payroll contributions stop automatically, but your employer may still be able to make additional contributions under certain circumstances.
The IRS adjusts the contribution limit each year for inflation, so the number you see this year may differ from next year.
Some employers offer a separate "non-elective" contribution that may have different rules; ask your plan administrator which type your employer uses.

How employer contributions are counted against your limit

When your employer makes a contribution to your 403(b), it reduces the amount you can contribute yourself that same year. This is true whether the contribution is a match (your employer puts in money because you did) or a non-elective contribution (your employer puts in money regardless of whether you contribute). Both types count the same way toward the annual ceiling.

For example, if your employer contributes $5,000 to your account in a given year, you can only contribute $18,500 of your own money (assuming the 2024 limit of $23,500 and you are under 50). Your payroll deductions will be adjusted automatically to stop once you and your employer together reach the limit. This is one reason it matters to know what your employer is putting in—it directly affects how much of your own salary you can defer.

What happens if you reach the limit mid-year

If you and your employer together hit the annual limit before December 31, your payroll contributions stop. Your employer cannot deduct more from your paycheck for that year. However, your employer may still be permitted to make a separate contribution after you have reached the limit, depending on the type of contribution and your plan's rules.

Some plans allow employers to make what is called a "true-up" contribution at year-end if you did not contribute enough early in the year to take full advantage of the match. For instance, if you were out on leave for several months and did not contribute, your employer might add extra money at the end of the year so you receive the full match you earned. This true-up contribution also counts toward the limit, so it is possible (though uncommon) to exceed the limit if not handled correctly. Your plan administrator should monitor this and prevent overfunding.

The difference between regular limits and catch-up contributions

If you are age 50 or older, you can contribute an additional $7,500 beyond the standard limit. This is called a catch-up contribution, and it brings your total to $31,000 for 2024. Your employer's contributions still count toward your regular $23,500 limit, but the catch-up space is yours alone—your employer cannot contribute to it on your behalf.

This means if you are 50 and your employer contributes $3,000, you can put in up to $28,000 of your own money ($23,500 regular limit minus $3,000 employer contribution, plus $7,500 catch-up). The catch-up amount is designed to help older workers save more as they approach retirement, and it is one of the few ways to exceed the standard limit.

Why limits matter for your retirement planning

Contribution limits affect how much you can save for retirement in a tax-advantaged way. If your employer offers a generous match, you may hit the ceiling before you have saved as much as you would like. In that case, you might consider opening an individual retirement account (IRA) to save additional money, though IRAs have their own contribution limits and rules.

Understanding the limit also helps you coordinate with your employer if you change jobs mid-year or take unpaid leave. If you have already contributed $15,000 to your 403(b) at one job and then move to a new job with a different 403(b) plan, your contributions at the new job are counted against the same annual limit. The two plans do not have separate ceilings—the IRS treats all your 403(b) contributions as one total for the year.

How the limit changes each year

The IRS adjusts the contribution limit annually to account for inflation. The increase usually happens in $500 increments. For example, the limit was $22,500 in 2023 and rose to $23,500 in 2024. The catch-up amount ($7,500 for those 50 and older) has remained the same for several years, but it too can change if inflation warrants it.

Your plan administrator or payroll department should notify you of the new limit each January. If you are planning to contribute the maximum, check with your employer early in the year to confirm the current number. Many people set their contributions based on the prior year's limit and then forget to update, which means they may not be taking full advantage of the increased space.

What to do if you think your employer is over-contributing

If you suspect your employer has contributed more than the law allows, contact your plan administrator or your employer's benefits department right away. Over-contributions are a compliance violation, and the excess money must be removed from your account. The sooner you catch the error, the easier it is to fix.

Your plan administrator is responsible for monitoring contributions and preventing overfunding, but mistakes can happen—especially if you work for multiple employers or if your employer uses an outside payroll processor. If an over-contribution is discovered, the excess is typically returned to your employer, and you may owe taxes on the earnings that accumulated on that excess money. This is another reason to review your 403(b) statements regularly and ask questions if the numbers do not match what you expect.

Frequently Asked Questions

Does my employer's contribution count toward the limit if I do not contribute myself?

Yes. Your employer's contribution counts toward the annual limit whether or not you contribute. If your employer puts in $10,000 and you contribute nothing, you have used $10,000 of your $23,500 limit. You cannot then contribute $23,500 of your own money—you can only contribute $13,500.

What if I work for two employers with 403(b) plans?

The annual limit applies across all your 403(b) plans combined. If you contribute $12,000 to one employer's plan and $11,000 to another, you have reached the $23,500 limit. Employer contributions at both jobs also count toward the same total. You are responsible for tracking this yourself; the plans do not communicate with each other.

Can my employer contribute more than I do?

Yes. There is no rule that says your employer's contribution must be smaller than yours. Some employers contribute a flat amount regardless of what you contribute, and that amount can exceed what you put in. As long as the combined total does not exceed the annual limit, it is allowed.

If I turn 50 mid-year, can I use the catch-up amount for the whole year?

No. The catch-up contribution is available only for the months during which you are age 50 or older. If you turn 50 in June, you can use the catch-up amount starting in June, not retroactively for January through May. Your plan administrator can help you adjust your contributions if this applies to you.

Are there any contributions that do not count toward the limit?

Most contributions count toward the limit, but there are narrow exceptions. Employer contributions made to correct a prior-year error, or certain rollover contributions from other retirement plans, may not count. Ask your plan administrator whether any special contributions at your workplace fall outside the standard limit.
