What a 401(k) Audit Involves

If your retirement plan has grown past 100 eligible participants, the Department of Labor requires an independent audit each year. It’s not optional, and getting it wrong means penalties, delayed filings, and closer scrutiny down the line.

We know this feels like one more item on an already long list. We work alongside your plan administrator and recordkeeper, reviewing plan documents, testing transactions, and verifying participant data so nothing slips through.

If we find gaps, we tell you early and in plain language. The goal is simple: a clean audit and a Form 5500 filing you can trust.

If your plan has 100 or more eligible participants at the start of the plan year, the Department of Labor generally requires an independent audit each year.

A limited scope audit relies on a qualified institution to certify investment data, reducing the work involved. A full scope audit tests all plan operations and controls directly.

Timing depends on plan size and how organized your records are, but most audits run four to six weeks from document collection to final report.

Auditors review plan documents, participant eligibility, contribution and distribution timing, and internal controls to confirm the plan operates the way it’s designed to.

We flag issues early and explain what caused them. Most errors can be corrected before filing, which is far better than the DOL finding them later.

Form 5500 is generally due seven months after the plan year ends, with a possible two and a half month extension if filed on time.

Businesses, nonprofits, and organizations sponsoring retirement plans with 100 or more eligible participants, including those newly crossing that threshold, typically need an annual audit.
