Why your plan may need an audit
If your 401(k) plan has 100+ eligible participants, ERISA typically requires an annual audit. Some smaller plans may also benefit from a voluntary review to confirm compliance and protect participants’ savings.
Why it matters
- Avoid penalties: Late or inaccurate filings can trigger steep DOL penalties.
- Ensure accuracy: Catch and correct contribution, eligibility, and distribution errors.
- Demonstrate fiduciary care: Build trust with employees and stakeholders.
Not sure whether you cross the threshold or qualify for the 80–120 participant exception? We’ll check that for you during your free consult.
