The 401(k) plan is a fundamental retirement planning tool for many Americans, but there is a limit to how much can be contributed every year. The IRS sets yearly maximums based on the pace of inflation, and exceeding them can result in penalties if not addressed.

Roth 401(k) contribution limits
The contribution limits for a Roth 401(k) plan are the same as with a traditional 401(k). If you have access to both accounts, you can contribute to each one as long as your cumulative contributions don't exceed the maximum 401(k) contribution limit.
After-tax 401(k) contribution limits
If you've maxed out your 401(k) contribution for the year as an individual, but your employer's contributions haven't met the combined limit, you may be able to make an after-tax 401(k) contribution. This will depend on your employer's plan provider.
After-tax contributions to a 401(k) plan refer to additional contributions employees can make after reaching their pre-tax or Roth contribution limits. Unlike pre-tax contributions, after-tax contributions do not reduce your taxable income in the year they are made, but they can still grow tax-deferred.
Additionally, they can be part of a mega backdoor Roth conversion, where these after-tax contributions are rolled into a Roth IRA, allowing future earnings to grow tax-free and providing tax-free withdrawals in retirement

401(k) max contribution limits for highly compensated employees
People who earn a high salary may be classified as highly compensated employees (HCEs) by the IRS. An employee is considered an HCE if they pass one of the tests below:
- Ownership test. A person who owns more than 5% of the company, regardless of compensation.
- Compensation test. A person who was in the company's top 20% of pay and received over a set number in compensation. For 2025 and 2026, that number is $160,000.
To ensure that HCEs don't benefit disproportionately to non-HCEs, the IRS requires nondiscrimination testing for all 401(k) plans. The two key tests are the Actual Deferral Percentage (ADP) test, which compares salary deferral rates between the two groups, and the Actual Contribution Percentage (ACP) test, which focuses on employer matching and after-tax contributions.
If the test determines that people across compensation levels aren't participating in a manner the IRS deems proportionate, employee contribution levels for HCEs can be lowered. In these cases, your employer may need to return some of your excess contributions .
What happens if I exceed my 401(k) limit by mistake?
If you contribute too much to your 401(k) and notice your mistake before the tax filing deadline, you can probably correct it with your employer. You’ll need to notify your plan administrator. If your plan allows excess deferral distributions, the plan administrator will return the money and any earnings to you and file a 1099-R for the year the excess contribution was distributed.
If you don’t catch the mistake before the deadline, you may have to pay taxes twice on the amount you contributed over the limit. That’s because 1) the excess contribution is taxable in the year it was made and 2) the IRS will still count that money as taxable in the year it’s distributed. Any earnings are also taxable in the year they are distributed, the agency says .
Frequently Asked Questions
Does my employer match count toward 401(k) limits?
No, your employer match does not count toward the 401(k) individual contribution limit.
However, there is a combined employee and employer 401(k) contribution limit, and the total combined contributions can't exceed this limit (see the table above).
Can I have a 401(k) and an IRA?
Yes. You can have both a 401(k) and an IRA. IRAs can be a good supplement to retirement savings, especially if you’re contributing enough to receive a full match from your employer or you’re planning on maxing out your 401(k).
You can make contributions to an IRA until that year's tax filing deadline.
