At a Glance
Accurate participant data is essential to effective retirement plan administration because errors in census information can affect eligibility, contributions, vesting and compliance. Plan sponsors can reduce risk by regularly reviewing payroll, human resources and recordkeeper data to identify issues before they lead to costly corrections or audit challenges.
When plan sponsors think about risks affecting their retirement plans, they often focus on investments, fees, fiduciary responsibilities or regulatory changes. While those areas certainly deserve attention, one of the most common sources of operational problems and compliance failures is far less complicated. That area is inaccurate participant data.
Every year, retirement plan auditors encounter issues that can be traced back to errors in employee census information. A simple mistake involving a hire date, termination date, compensation amount or participant status can create a ripple effect throughout the plan, resulting in administrative challenges, correction costs and unnecessary compliance risk.
Maintaining accurate participant data is not simply a good administrative practice. It is a critical component of effective plan governance.
Participant census data serves as the foundation for nearly every aspect of plan administration. Information maintained in payroll, human resources and recordkeeping systems is used to determine:
- Eligibility for plan participation
- Eligibility for employer matching contributions
- Vesting percentages
- Participant contribution amounts
- Matching contribution calculations
- Distributions and required notices
- Regulatory reporting
- When participant data is inaccurate or inconsistent across systems, errors often follow.
The most common data issues found during plan audits are the following:
Incorrect Hire Dates
Because eligibility and vesting calculations often depend on an employee’s date of hire, a simple error can lead to employees entering the plan too early or not being allowed to participate when they become eligible. It can also lead to incorrect vesting calculations which may lead to a participant forfeiting too little or too much of their employer matching contributions.
Compensation Errors
Retirement plans frequently define compensation differently than payroll systems. Errors involving bonuses, overtime, commissions and payroll coding can affect contributions and employer matches. In many cases, when this is done incorrectly, the plan sponsor has to correct errors to participants out of company funds.
Inaccurate Termination Information
When former employees remain classified as active, plan sponsors may maintain outdated participant records and increase missing participant risk. Incorrect termination information also can affect vesting and forfeitures for a participant.
Date of Birth Errors
Date of birth errors can affect plan eligibility, catch-up contribution eligibility, and required minimum distributions.
Many missing participant situations begin with outdated addresses, incorrect email addresses or incomplete termination records. Organizations that proactively update participant records are better positioned to reduce risk and fulfill fiduciary responsibilities. Auditors rely on participant data to test eligibility, contributions, matching calculations, distributions, participant counts and demographic information. Reliable census data supports a more efficient audit process.
There are steps that plan sponsors can take that help to reduce the risk of inaccurate data. Some of those steps are as follows:
- Reconcile payroll records to participant census data annually.
- Verify hire dates and termination dates for accuracy.
- Review employee classifications and eligibility determinations.
- Compare payroll compensation codes to the plan’s compensation definition.
- Validate dates of birth and other key participant information.
- Review participants with returned mail or inactive email addresses.
- Reconcile payroll and recordkeeper reports throughout the year.
- Establish procedures for updating participant information when employees terminate employment.
Accurate participant information supports effective plan administration, reduces compliance risk, improves participant outcomes and helps create a smoother audit experience. For plan sponsors looking to improve the health of their 401(k) plan, reviewing the quality of participant census data may be one of the most impactful places to start.
