While this is not meant to be a complete listing of all the information that will be needed for a 401(k) Plan audit, we do believe it can be used as a checklist to prepare for an upcoming audit. It is also a good list to use for retention policy purposes.

As an audit may not be needed for the current plan year, it may be required in the future. Auditors are required to verify beginning balances in all first audits. This will require reviewing prior year information. In those cases, the above information will be needed for years before the year being audited. For that reason, we encourage developing a document retention policy for your 401(k) plan that reviews all of the above information.

This will ensure that if and when an audit is required, you will be able to provide the auditor with the necessary information quickly and without significant administrative time on your end to locate the needed documents.
