What Triggers a 401(k) Audit and How to Avoid It

Avoid costly 401(k) audits by understanding common triggers. Learn what regulators look for and how to stay compliant.

A 401(k) audit can be time-consuming, stressful, and expensive—but many are preventable.

One of the most common triggers is rapid company growth. When a plan reaches a certain number of participants, an audit may become required.

Late contributions are another red flag. Regulators closely monitor how quickly employee deferrals are deposited.

Inconsistent data—such as payroll discrepancies or incorrect reporting—can also attract attention.

Additionally, repeated compliance testing failures or missing documentation may increase the likelihood of an audit.

The best way to avoid issues is through proactive management. Accurate recordkeeping, timely contributions, and regular reviews can go a long way in reducing risk.

Conclusion:

Audits don’t happen randomly—there are clear warning signs. Staying organized and proactive helps protect your business and helps ensure a smoother process if an audit occurs.
