Ask the Audit Expert: Understanding Workers’ Comp Audit Types

Q: Historically, a premium auditor has contacted me to conduct a premium audit at my business. This year, I was asked to complete forms to return by mail. Why did the auditor not schedule a visit this year?

Answer: Policies can be audited in several ways. At CompSource Mutual, we have four types of audits.

 Read on to learn more about the premium audit process. 

  1. Field Audit

For a Field Audit, one of our auditors will schedule an on-site visit to review the policyholder’s records. Field Audits can take place at the business or the office of the policyholder’s accountant or bookkeeper. 

  1. Mail Review Audit

With the Mail Review Audit, CompSource Mutual mails the policyholder an audit packet to fill out and return along with supporting documentation. This can be a very easy and time-saving alternative to a Field Audit. 

  1. Interim Audit

The Interim Audit is a quarterly or semiannual on-site visit scheduled by CompSource Mutual to review the policyholder’s records. These are informational audits and are not typically billed. While the Field Audit and Mail Review Audits serve the same purpose, the decision on which type CompSource Mutual uses for each business is based on several factors specific to the business. 

  1. Self-Audit

This type of audit is completed online by the policyholder. Customers selected for this type of audit will receive a letter containing a code to log in online. Policyholders are walked through a series of questions, prompted to provide pertinent details, and will upload verifying information.  Take a look at FAQs related to the self-audit process with CompSource Mutual.
