Accidentally exceeding your 401(k) contribution limit can lead to tax consequences, but it’s an issue that can be resolved if you act quickly. For 2025, the IRS has set the 401(k) contribution limit at $23,000 for individuals under 50. Those 50 or older can contribute up to $30,500, which includes a $7,500 catch-up contribution.
Steps to Correct Excess Contributions
If you contribute more than the allowable limit, the IRS requires that the excess be corrected by April 15, 2026. To fix the issue, contact your 401(k) plan administrator and request a corrective distribution. This means withdrawing the excess amount along with any earnings it generated.
The withdrawn amount will be reported as taxable income for 2025, the year the contribution was made. However, any earnings on the excess amount will be taxed in the year the distribution is made, which is typically 2026 if you act by the deadline.
Consequences of Not Correcting Excess Contributions
Failing to correct the excess contribution by the April 15 deadline can lead to double taxation. This occurs because the excess amount will be taxed both when it was initially contributed and again when it is eventually withdrawn during retirement. You may also face additional penalties and taxes on any earnings associated with the excess.
For example, if you contributed $2,000 over the limit in 2025 and didn’t remove it by April 15, you would be taxed on that $2,000 when it was originally contributed. You’d then be taxed again when you withdraw it in the future, effectively paying tax twice on the same amount.
How to Avoid Over Contributions
To prevent exceeding the limit, monitor your contributions regularly. This is especially important if you have multiple 401(k) plans or changed jobs during the year. Consider setting up automated alerts or working with your plan administrator to ensure you don’t surpass the IRS limit.
If you’re unsure of your contribution status or need help managing retirement plan limits, consulting with a financial advisor can be a smart move. They can help you stay compliant and avoid unnecessary tax headaches.
