Frequently Asked Questions
An ERISA audit is an independent examination of your employee benefit plan’s financial statements, required under the Employee Retirement Income Security Act once your plan reaches 100 or more eligible participants. If you’ve crossed that threshold, this audit becomes part of your annual Form 5500 filing, not an optional add-on.
Staying compliant means keeping your plan documents accurate and up to date, filing Form 5500 every year, bringing in an independent auditor once your plan requires it, and administering contributions and distributions according to your plan’s actual terms. It’s easy for one of these to slip, especially around plan document updates, so it’s worth reviewing your compliance checklist annually rather than only thinking about it at filing time.
Our resource pages walk through the practical side of ERISA audit requirements, and our employee benefit plan audit team is available if you have questions specific to your plan. If you’re not sure whether something applies to your situation, it’s usually faster to just ask than to try to piece it together from general guidance.
