Common 401(k) mistakes can lead to penalties and added costs. Learn what to watch for and how to keep your retirement plan compliant.
Offering a 401(k) plan is a smart move—but simple mistakes can quietly cost your business more than you realize.
One of the most common issues I see is late employee contribution deposits. The Department of Labor requires employers to deposit contributions as soon as reasonably possible. Delays can trigger penalties and require corrective actions.
Another frequent mistake I see is incorrect employer matching. Even small calculation errors, when repeated over time, can create significant liabilities. Businesses may discover these issues only during audits—when fixing them can become more expensive.
Plan documents are another overlooked area I see. If your plan isn’t updated regularly to reflect current regulations, you may already be out of compliance without realizing it.
Finally, I see many businesses that fail to properly monitor eligibility. Excluding employees who should be participating can lead to required contributions and lost earnings corrections.
Conclusion:
Small administrative mistakes can have financial consequences over time. By staying proactive and regularly reviewing your plan, you can help avoid unnecessary costs and keep your retirement program running efficiently and compliantly.
