About the audit process

What is a workers comp audit?

A workers' compensation policy audit is a review of your payroll and operations to ensure your premiums accurately reflect your risk.  It verifies that your business is classified correctly and that your reported payroll matches your actual payroll, which may result in either a refund or additional premium due.

Pinnacol Assurance audits each policy at the end of the policy period

To ensure that the premiums you pay for your workers’ compensation are accurate, and to determine whether you are eligible for a return of premium, Pinnacol Assurance audits each policy at the end of the policy period. Here’s why.

Why audit?

Because your premium is calculated using estimated figures, it’s important for us to look at your premium using your actual payroll and exposures. These audits sometimes result in a return of premium. In addition, audits help ensure that no business has an unfair advantage because of incorrect classification or payroll assignment.

During an audit, the following information will be reviewed:

  • Ownership status
  • Business operations
  • Duties of employees
  • Payments to subcontractors
