Missing participants in a 401(k) plan aren’t just an administrative issue — they can create compliance and fiduciary risks for plan sponsors. When former employees retain account balances but cannot be located, it becomes more difficult to ensure participants receive their benefits and to maintain accurate plan records.

If you’re preparing for an audit, it helps to confirm participant data and communication processes in advance using a 401(k) audit checklist. 

Why Missing Participants Create Audit Issues 

Missing participants are not just a recordkeeping issue — they often surface during a 401(k) audit. If participant records are incomplete or outdated, it becomes difficult to confirm that distributions were properly processed and that funds were actually delivered. 

In some cases, auditors may need to perform additional procedures to verify participant balances and transaction history. Gaps in documentation or unresolved participant accounts can increase audit complexity and create potential compliance concerns. 

Key Takeaways: 

• Plan sponsors have a fiduciary responsibility to ensure all participants, even terminated ones, have access to their funds 

• Missing participant issues often develop gradually over time. Employees may change jobs, move or fail to update their contact information, and in some cases, plan processes may not include consistent follow-up after distributions are initiated. These small gaps can build into larger administrative challenges. 

• Take preventative and preparatory measures to maintain contact with Plan participants by working with them to either move their funds to another Plan or have them take cash withdrawals before their exit to avoid this scenario.  

Department of Labor Taking Steps to Address Issue  

The Department of Labor (DOL) has been trying to find a way to help employers with missing participants. They don’t like the situation in which an employee has saved money into a 401(k) Plan but then cannot get access to it when they are ready to retire or may need the funds in the case of an emergency. The goal is to set up a dedicated team to help participants locate their missing funds. 

Vulnerable Plan Participants Increase Urgency for a Solution 

During 2021, the Employee Benefits Security Administration (EBSA) located $1.5 billion in lost benefits for more than 16,000 participants. This shows the extent of the problem. Many of these impacted individuals were elderly and living on very small incomes without knowing or understanding that they had retirement income sitting in an account that they could access. EBSA would like the project team to identify industries in which this problem may be most acute. 

One area EBSA is especially concerned about is non-English speaking participants. Most notices and forms are provided in English and may be ignored if the participant does not speak English or does not understand the terminology used. They suggest employers ask their service providers for forms and booklets in other languages to assist in plan administration for all participants. Also, work with the service providers to provide clear instruction on how to assist employees in consolidating accounts from previous employers. 

Listed below are actionable steps a Plan sponsor or administrator can take to ensure participants have continued access to their benefit funds, even if they terminate employment, move or change phone numbers. 

Take Preventative Measures 

We have discussed ways to avoid this problem by working with terminating employees to have their money moved as soon as possible into another Plan. One way to avoid this situation is to provide information to all employees as they are exiting and follow up with them to ensure they take steps to move the money. 

Update or Add Plan Provisions to your Plan Document 

Consider including a Plan provision in your Plan Document so that you can move funds to an individual account without requiring the participant’s consent after termination of employment if the funds are smaller (for example less than $1,000 or less than $5,000). 

Doing so will allow you to move the funds to another account or Plan while you still have the participant’s address and you can let them know of the transaction for their action in the future. This relieves you of the responsibility of trying to reach terminated employees years into the future. 

Consider Implementing These EBSA Suggestions 

In the meantime, EBSA suggests establishing a better mechanism inside your company to maintain the address and other contact information for participants that no longer work with your company. This includes retired individuals that have not yet begun any distributions out of their account. 

Locating missing participants can be time-consuming, but it is an ongoing responsibility for plan sponsors. Regulators expect reasonable and documented efforts to locate participants and ensure their benefits are delivered as intended. 

Stale Checks vs. Missing Participants 

Not all missing participant issues are the same. In some cases, distributions have already been processed, but the participant never received or cashed the check. These “stale checks” can create additional complications because funds have already been removed from the plan but are still owed to the participant. 

This creates reconciliation challenges and increases the responsibility on plan sponsors to locate the participant or take corrective action. Differentiating between missing participants and uncashed distributions is an important step in maintaining accurate plan records. 

Use All Available Tools to Ensure Compliance 

Lastly, there are databases searchable online to assist in locating missing participants. In the case of a deceased participant, it is important to make sure you have current beneficiary information in the participant file. Most often, service providers ask that employers maintain this information and update it periodically. These types of issues often surface during audits or plan reviews, especially when participant records are incomplete or outdated. 

We recommend Plan Sponsors implement a practice to have their employees and terminated or retired participants review the beneficiary information on a periodic basis to ensure it is current and that there will not be issues in the event of the death of a participant. 

In some cases, unresolved participant balances or uncashed distributions may be confused with forfeiture or holding account balances. Clearly tracking and resolving each situation is important to avoid misclassification and ensure proper plan administration. 

Addressing missing participant issues early can reduce administrative burden and minimize audit risk. Ensuring participant records are accurate and distributions are properly handled is a key part of audit readiness and ongoing plan compliance.
