SD Mayer & Associates employee benefit plan auditors can examine your financial statements to ensure that they are accurate and formatted under the U.S. Generally Accepted Accounting Principles (GAAP). These audits cover plan contributions, investments, benefits payments, administrative costs and much more to gain reasonable assurance and protect against fraud and abuse. As one of the most established employee benefit plan audit firms, we have the expertise to perform employee benefit plan services for:

  • 401(k) audits: A DOL 401(k) audit with our experts will verify the accuracy of your Form 5500 and ensure that your 401(k) plan complies with DOL and Internal Revenue Service (IRS) requirements.
  • 403(b) audits: Nonprofits and schools with 403(b) retirement plans, also known as tax-sheltered annuity (TSA) plans, can take advantage of our professional 403(b) employee benefit plan services.
  • Employee Stock Ownership Plans: Employee Stock Ownership Plans (ESOPs) fall under the Internal Revenue Code and qualify as a 401(a) employee contribution plan that must be audited as a part of annual filings.
  • Defined contribution plans: If your organization utilizes a defined contribution plan, like a tax-deferred 401(k) or 401(b), our employee benefit plan auditors will verify employer and employee contributions and plan payouts.
  • Health and welfare benefit plans: Our employee benefit plan services include expert audits for all health and welfare employee benefits provided by a company, including programs for health care, dental, vacation time, tuition assistance and more.


If your business or organization operates a benefits program with 100 participants or more, you must retain an independent firm for your annual audit. Title I and Title IV of the Employee Retirement Income Security Act of 1974 (ERISA) and the Internal Revenue Code require that you attach an independent financial audit statement to your annual Form 5500 submission to the Department of Labor (DOL).
