Our 401(k) Audit Process

Why the Audit Process Matters
A 401(k) plan audit isn’t just about checking a box for compliance—it’s about ensuring that your retirement plan is being managed properly and that participant funds are protected. By following a clear process, we help plan sponsors:
- Reduce fiduciary risk
- Identify and correct compliance issues early
- File Form 5500 with confidence
- Improve plan operations over time
Step-by-Step 401(k) Audit Process

Step 1 – Planning & Document Collection
We start by gathering key plan documents, including plan descriptions, financial statements, payroll records, and service provider reports. Our team reviews your plan structure and identifies the specific requirements for your audit.

Step 2 – Compliance Testing
We perform detailed testing of plan activity, including:
Employee and employer contributions
Participant eligibility and enrollment
Distributions and loans
Timeliness of contributions
Internal controls and plan operations
This ensures your plan is compliant with DOL, IRS, and ERISA rules.

Step 3 – Financial Review
Our auditors examine the plan’s financial statements, investments, and related disclosures. We ensure accuracy, transparency, and compliance with reporting standards.

Step 4 – Audit Report Preparation
We prepare the formal audit report required for your Form 5500 filing. Our report provides a clear, independent assessment of your plan’s compliance and financial condition.

Step 5 – Filing & Ongoing Support
We coordinate with your team to finalize and file the audit report alongside Form 5500. Beyond the audit, we provide recommendations to strengthen compliance and support your plan’s long-term success.
