FREQUENTLY ASKED QUESTIONS – 401K PLAN AUDIT REQUIREMENTS
Do you need a 401K audit? If so, now what? We have answers to all of your EBP audit questions. Click the link below to download the full list of FAQs.
WHEN IS A 401K PLAN REQUIRED TO BE AUDITED?
An audit is required to be performed by a qualified third party CPA firm when certain conditions are met, primarily when total participants with account balances reach 100 and the plan is deemed a "large" plan, plans that are required to file Schedule H with the Form 5500.
WHY SHOULD I LOOK FOR AN AUDIT FIRM THAT IS A MEMBER OF THE EBPAQC?
Studies by the Department of Labor of employee benefit plan audits show a much smaller deficiency rate in firms that belong to the EBPAQC than those that do not. This is a very significant factor to consider, given the fiduciary responsibility of the plan sponsor to have a quality audit performed.
I NEED AN AUDIT, WHAT’S NEXT?
First, you will need to determine what type of audit you need - an ERISA Section 103(a)(3)(C) audit or a Non-ERISA Section 103(a)(3)(C) audit.
WHAT IS THE AUDIT FILING DEADLINE?
The audit report must be attached to the Form 5500, so it is subject to 5500 filing deadlines. The 5500 is due seven months after the last day of the plan year, but may be extended for an additional two and a half months.
WHAT DOES A 401K AUDIT INVOLVE?
A 401(k) plan audit includes a thorough review of financial statements, footnotes, contributions, distributions, participant loan balances, participant account balances, and plan operations to ensure compliance with the plan document, DOL and ERISA regulations. Our CPA team examines participant accounts, plan records, payroll records and fiduciary practices to support our audit opinion. This information comes both directly from the plan sponsor and from the plan third party service providers.
CAN A CPA FIRM ASSIST WITH BOTH THE AUDIT AND TAX COMPLIANCE FOR A 401(K) PLAN?
Yes. A full-service CPA firm can handle audit preparation, financial reporting, and Form 5500 tax preparation for your 401(k) plan. This integrated approach can reduce errors and can simplify the process for plan sponsors.
HOW MUCH DOES A 401(K) PLAN AUDIT TYPICALLY COST?
Audit cost will vary depending on plan size, complexity, type of investments held in the plan and participant count. A specialized CPA firm can provide a transparent estimate based on your plan’s unique characteristics and help manage audit-related expenses effectively.
WHAT DOCUMENTATION DOES A CPA FIRM NEED TO CONDUCT A 401(K) PLAN AUDIT?
Common documentation includes plan document and any amendments, service provider contracts, participant census data, contribution and distribution records, participant loan support, certified investment statements, payroll records, employment agreements, and prior year audit reports. Providing organized records helps ensure a smooth and timely audit process.
