Our Employee Benefit Plan Audit team completes more than 275 audits annually and supports extensive Form 5500 filings. We handle all types of Employee Benefit Plan Audits, including those with alternative investments, master trusts, and terminating plans.
We specialize in ERISA Employee Benefit Plan Audits for large plans over the 100‑participant threshold, while our Form 5500 team ensures compliance for plans of all sizes. We also assist with M&A due diligence, uncovering and correcting issues that could affect plan qualification or attract regulatory scrutiny. Our Employee Benefit Plan Audit practice undergoes regular quality oversight, including a peer review by the American Institute of Certified Public Accountants (AICPA) every three years and Public Company Accounting Oversight Board (PCAOB) inspections approximately every three years. The U.S. Department of Labor (DOL) last conducted an inspection about four to five years ago. Together, these review processes reinforce our commitment to audit quality.

Frequently asked questions
See below for answers to common EBP-related questions.
Who is required to have an employee benefit plan audit?
Generally, plans with 100 or more participants with an account balance at the beginning of the plan year are required to undergo an audit. This rule applies to plan years beginning on or after January 1, 2023, and is based on participants with a balance, not just eligible participants.
What types of employee benefit plans are subject to audit requirements?
Plans covered under ERISA, including 401(k), 403(b), defined benefit plans, Employee Stock Ownership Plans (ESOPs) and health and welfare benefit plans, may require an annual audit depending on participant count and plan characteristics.
What is the purpose of an employee benefit plan audit?
An audit provides assurance that the plan’s financial statements are accurate, evaluates compliance with the plan document and ERISA, and helps identify internal control, compliance and/or operational issues. It also supports the plan administrator in filing a complete and accurate Form 5500.
What is included in an employee benefit plan audit?
Auditors examine plan operations, participant data, contributions, distributions, investment information, internal controls, and compliance with ERISA and IRS requirements. They will also review plan documents and service provider reports.
How long does an employee benefit plan audit take?
Depending on plan complexity and how prepared the sponsor is with required documentation, audits may take several weeks to multiple months. Starting early and responding promptly to auditor requests shortens the timeline.
What are common issues auditors uncover during employee benefit plan audits?
Common findings often involve participant data errors, timeliness of contributions, distribution processing errors, loan repayment errors or documentation inconsistencies. These align with areas the U.S. Department of Labor has identified as frequently deficient across the industry.
How can plan sponsors prepare for an employee benefit plan audit?
Plan sponsors should gather required plan documents, ensure internal controls are operating effectively, coordinate with service providers frequently, and review plan alignment with Department of Labor requirements. Early preparation can potentially improve efficiency and audit timeliness.
Why is selecting the right employee benefit plan auditor important?
A qualified auditor helps protect plan assets, ensures regulatory compliance, reduces risk of DOL findings, and supports accurate financial reporting. ERISA requires the auditor to be a licensed, independent CPA with EBP-specific experience. [dol.gov]
