Retirement Plan Auditors: Ensuring Compliance and Accuracy

Operating a retirement plan comes with significant fiduciary responsibilities. For organizations with 100 or more participants, an annual audit by qualified retirement plan auditors is not just a best practice—it is a mandatory requirement under the Employee Retirement Income Security Act (ERISA). Partnering with the right audit firm ensures that your plan's financial statements are accurate and that you remain in good standing with the Department of Labor (DOL) and the IRS.

Specialized Retirement Plan Audit Services

Not all audit firms possess the specialized knowledge required to navigate the complexities of specific retirement plan structures. Our directory helps you connect with firms that have deep expertise in the following areas:

  • 401(k) Auditor Services: Comprehensive reviews designed to verify internal controls and ensure compliance for defined contribution plans.
  • 403(b) Auditor Services: Tailored audit solutions for tax-exempt organizations managing 403(b) retirement programs.
  • EBP Audit Services: General Employee Benefit Plan audit support for a wide range of organizational requirements.

Preparing for Your Annual Audit

Understanding the audit process is key to a smooth filing season. Whether you are conducting your first audit or looking to switch firms, our library of resources provides the information you need to stay compliant.

Key Audit Concepts

Beyond the Audit: Strengthening Your Plan Compliance

While the annual audit is a critical compliance checkpoint, maintaining a successful retirement plan requires a holistic approach. Ensure your team has access to the right legal and protective resources:

  • Consult with Experts: If your audit reveals procedural gaps, you may need to consult with an ERISA attorney to rectify plan documents.
  • Financial Protection: Review your fiduciary responsibilities to ensure your organization is adequately covered. You can learn more about the requirements for ERISA bonds through our dedicated provider network.

Don’t leave your plan's integrity to chance. Use our comprehensive directory of retirement plan auditors to find a firm that aligns with your specific organizational needs and plan type today.
