Beyond the benefit plan audit: Why compliance assessments matter

February 19, 2026 / 4 min read

Annual benefit plan audits meet reporting requirements, but they’re not intended to consider all ERISA legislative and regulatory requirements. Compliance assessments provide a comprehensive, in-depth view of operational risks and control gaps, enhancing compliance and supporting stronger benefit plan governance.

A qualified plan offers significant tax benefits to both employers and employees. As such, it’s subject to many rules and requirements that the plan must meet to be qualified. For large retirement plans that have a benefit plan audit requirement, this annual reporting process serves as a valuable check on the financial reporting of a benefit plan, but it may not provide the type of deeper analysis that can help an employer strengthen protections and streamline processes.

Employers are increasingly turning to compliance assessments to more thoroughly examine and evaluate their benefit plans. These proactive, sponsor-initiated reviews of plan operations and processes can help to identify and mitigate compliance risks, operational errors, and weaknesses in internal controls before they become significant problems or are found in a formal Internal Revenue Service (IRS) or Department of Labor (DOL) audit.

Employee benefit plan audits support ERISA compliance

The benefit plan audit that accompanies the annual Form 5500 filing is conducted in accordance with the rules set forth in federal regulations. The audit is designed to obtain reasonable assurance that the plan’s financial statements are free of material misstatement by performing prescribed audit procedures to a sample of transactions, including consideration of plan provisions that may pose a risk of material misstatement. The resulting financial report, including the audit opinion, is attached to the filing and available for public review. Without this audit, the employer is out of compliance with federal benefit plan requirements and is subject to significant fines, penalties, and other administrative actions by the Department of Labor (DOL) and the Internal Revenue Service (IRS).

Compliance assessments typically offer a deeper analysis over a broader scope

In contrast, a compliance assessment digs deep into a plan’s administrative procedures and operations before potential issues are identified by the IRS or DOL. These assessments are an effective, proactive measure to safeguard against these risks. Given the number of rules applicable to qualified plans, it’s likely that mistakes will occur. A compliance assessment can help identify and correct potential costly mistakes.

While an annual benefit plan audit tests similar areas as part of its required procedures, it does so on a sample basis and in the context of financial statement reporting. A compliance assessment, however, is intentionally broader and more detailed, often involving a participant-by-participant and payroll-by-payroll review of plan transactions. This approach equips plan sponsors with greater insight into compliance risks, potential correction costs, and opportunities to strengthen internal controls and plan administration.

Differences between the benefit plan audit and compliance assessment

In essence, a compliance assessment is a preventative, self-initiated inspection, while an employee benefit plan audit is a mandatory, annual third-party verification required for ERISA compliance that carries enforcement authority and potential penalties for noncompliance.

A common misconception is that the annual benefit plan audit focuses on all areas of ERISA compliance. It’s important to note that an employee benefit plan audit is designed to address financial reporting compliance under ERISA by providing reasonable assurance over the plan’s financial statements — not to evaluate full operational compliance with all ERISA requirements.

The following highlights some of the key differences between a “DOL” benefit plan audit and a compliance assessment.
