Employer contributions do count toward your annual 401(k) limit

Your employer's contributions to your 401(k) are subject to the same annual limit as your own payroll deductions. The IRS sets a combined ceiling on all money going into your account in a single year — whether it comes from your paychecks, your employer's match, or profit-sharing contributions. For 2024, that limit is $69,000 for most workers under 50. If your employer contributes $10,000 and you contribute $20,000, you have used $30,000 of your $69,000 limit.

This matters because it means a generous employer match can actually reduce how much of your own money you can put in. If you hit the annual limit through a combination of your contributions and your employer's, you cannot contribute more that year, even if you have the money available.

Key Takeaways

  • Your contributions and your employer's contributions are added together and must stay under the annual IRS limit, which is $69,000 for 2024.
  • If your employer contributes a large match or profit-sharing amount, you may reach the limit before you can contribute as much of your own salary as you want.
  • Workers age 50 and older can contribute an additional $7,500 catch-up amount, bringing their total limit to $76,500 for 2024.
  • Your employer's contributions do not reduce the limit on how much you can defer from your paycheck — only the total account limit matters.

How the combined limit works in practice

The IRS limit applies to the total amount deposited into your 401(k) account during the calendar year. Your plan administrator tracks both your deferrals (money taken from your paycheck) and your employer's contributions (match, profit-sharing, or other employer-funded amounts) together. When the combined total reaches the annual limit, contributions stop, regardless of which party is contributing.

For example, suppose you earn $100,000 and your employer matches 50 percent of your contributions up to 6 percent of your salary. If you defer $20,000 from your paycheck, your employer contributes $3,000 (50% of 6% of $100,000). Your total for the year is $23,000, well under the limit. But if you defer $60,000 and your employer contributes $9,000, you have used $69,000 and hit the ceiling — you cannot defer another dollar that year.

The limit is per person, per year. It resets on January 1. If you change jobs mid-year, contributions to both your old plan and your new plan count toward the same annual limit.

What counts as an employer contribution

Employer contributions take several forms, and all of them count toward your limit. A matching contribution is the most common — your employer deposits money based on how much you contribute (typically 50 to 100 percent of your first 3 to 6 percent of salary). A profit-sharing contribution is money your employer adds based on company profits or a formula, regardless of whether you contributed anything. Some employers also make non-elective contributions, which are mandatory employer deposits for all may be able to access employees.

Employer contributions also include any after-tax contributions your employer allows you to make beyond the regular limit, though these are less common. Rollovers from other retirement accounts and loan repayments do not count toward the limit.

The difference between your deferral limit and the total limit

The IRS actually sets two separate limits. The employee deferral limit is how much of your own salary you can set aside — $23,500 for 2024 (or $30,500 if you are 50 or older). The total contribution limit is the combined ceiling for you and your employer — $69,000 for 2024 (or $76,500 if you are 50 or older).

This means your employer's contributions do not reduce how much you personally can defer from your paycheck, up to the employee deferral limit. But they do count toward the total. If you defer $23,500 (the maximum for your age group) and your employer contributes $50,000 in profit-sharing, your account has received $73,500 — which exceeds the total limit. Your plan administrator will typically reduce the employer contribution or return the excess to your employer.

What happens if contributions exceed the limit

If your plan administrator catches an overage, they will correct it before the end of the year. For employee deferrals, excess contributions are usually returned to you as taxable income, and you may owe taxes and penalties on the overage. For employer contributions, the excess is typically returned to your employer or forfeited, depending on your plan's rules.

Some plans use a testing process called ADP testing (Actual Deferral Percentage) to make sure highly paid employees are not contributing too much relative to other workers. If your plan fails this test, excess contributions from high earners may be returned to you mid-year. Your plan administrator should notify you if this happens.

The best way to avoid an overage is to monitor your contributions throughout the year, especially if your employer makes large profit-sharing or bonus contributions. Many plan websites show your year-to-date total, and your HR department can tell you what your employer plans to contribute.

Catch-up contributions and the employer limit

If you are 50 or older, you can make an additional catch-up contribution of $7,500 per year (for 2024), raising your employee deferral limit to $30,500. This catch-up amount is separate and does not affect how much your employer can contribute. Your total account limit still rises to $76,500, but the extra $7,500 is reserved for your own deferrals only.

Employer contributions still count toward your total limit of $76,500. If your employer contributes $50,000 and you defer $30,500 (including your catch-up), you have used $80,500 — exceeding the limit. Again, your plan will correct this by reducing or returning the excess.

How to track your contributions throughout the year

Most employers provide online access to your 401(k) account through the plan's website or a mobile app. Log in periodically to check your year-to-date contributions from both your paycheck and your employer. This number should appear on your quarterly or annual statement.

If you change jobs during the year, keep track of contributions to both your old and new 401(k) plans. The limit applies across all plans combined, not per plan. If you are unsure whether you are approaching the limit, contact your plan administrator or your HR department — they can tell you exactly how much you have contributed so far and how much room you have left.

Frequently Asked Questions

Can my employer contribute more than I do?

Yes. Your employer can contribute any amount up to the total limit, regardless of how much you contribute. Some employers make large profit-sharing contributions even if you defer nothing. However, if the combined total exceeds the annual limit, the excess will be corrected by your plan.

Does my employer's match reduce how much I can contribute?

No, not directly. You can still defer up to $23,500 of your own salary (or $30,500 if you are 50 or older). But the match does count toward your total account limit of $69,000 (or $76,500). If the match plus your deferrals exceed that total, the excess will be handled by your plan.

What if my employer contributes after I hit the limit?

Your plan administrator will stop accepting contributions once the total reaches the annual limit. If your employer tries to make a contribution after that point, it will typically be returned to the employer or forfeited, depending on your plan's rules. Your plan should notify you and your employer when the limit is reached.

Do employer contributions affect my taxes?

Employer contributions are not taxed as income in the year they are made — they grow tax-deferred inside your 401(k). You pay taxes on both your contributions and your employer's contributions when you withdraw the money in retirement. Excess contributions that are returned to you are taxed as ordinary income in the year they are returned.

If I leave my job mid-year, do employer contributions still count toward the limit?

Yes. Any employer contributions made before you leave count toward your annual limit. If you start a new job and contribute to a different 401(k), both plans' contributions are added together for the year. Make sure to tell your new employer how much you have already contributed so they can help you stay under the limit.
