What you need to know about 401(k) audit requirements

Your retirement plan audit can be daunting, but it doesn’t have to be. The blend of compliance and financial factors makes these audits complex, but by knowing what to expect and working with a team of experienced professionals, you can stay ahead of the game. The following reviews the basic 401(k) audit requirements so you can get started confidently.

What is a 401(k) audit?

Generally required for plans with more than 100 participants with account balances on the first day of the plan year, employee retirement plan audits are required for “large” plans. They are official inspections to ensure that the plan meets guidelines and regulations set by the Internal Revenue Service (IRS) and the Department of Labor (DOL). Audits must be conducted by an independent accounting firm using Generally Accepted Audit Standards (GAAS). They also need to adhere to DOL and Employee Retirement Income Security Act (ERISA) of 1974 regulations.

An employee pension audit serves two primary purposes:

  1. to ensure that your plan complies with DOL and IRS regulations, along with the plan-related documents, and
  2. to determine that the financial information reported on Form 5500 and company financial statements is accurate and in compliance with Generally Accepted Accounting Principles (GAAP).

What does a 401(k) audit involve?

Once you and your third-party administrator (TPA) determine that you need an audit, the next step is to hire a qualified CPA firm like BPM to conduct the audit.

Unlike financial statement audits, much of the audit information will be provided to your audit firm directly from your TPA. It is important to determine whether you are in audit status as soon as possible and provide sufficient time for the audit process in advance of the audit deadline.

Important dates (for calendar year-end plans)
January 31: The date by which your employee census must be submitted to your TPA.
March 15: The date by which your TPA should tell you if you are in audit status.
July 31: Initial deadline to complete the audit and file Form 5500.
October 15: Extended deadline to complete the audit and file Form 5500.
