Premium Workers' Compensation Audits

What is a Workers’ Compensation Audit?

When a workers’ comp policy is written, the premium amount is based on your business’s estimated annual payroll and assumed risks for the specified policy period. At the end of the policy period, an audit is conducted to determine your actual payroll and calculate the final premium.

What to Expect During an Audit

During a premium audit, we request information including but not limited to the following:

  • Company information
  • Ownership information
  • Business address
  • Phone and fax numbers
  • Accountant contact information, if applicable
  • Changes about the company during the policy period
  • Average number of employees

Business records that relate to how your premium is calculated will also be necessary for the audit.  These records include but are not limited to:

  • Tax reports
  • Payroll records, including documentation of any overtime hours
  • Bank statements and check registers
  • General accounting ledgers and/or Financial Statements
  • Subcontractor information

During the premium audit process, the premium auditor will also review your documentation to see if you qualify for credits that can reduce your final premium. One of the credits many policy members take advantage of is overtime credit. Based upon our review of your payroll records, CompSource Mutual may allow you to exclude a portion of your overtime wages from the payroll used to calculate your workers’ compensation premium for each class code. Following the audit, a summary of the results will be mailed to you.

For a more in-depth explanation of the process, see CompSource Mutual’s “Understanding the Premium Audit Process” brochure.
