The Workers’ Comp Audit: Your Essential Survival Guide
You open your mail and there it is—a letter from your workers’ compensation insurance carrier about your upcoming audit. Before you panic, take a deep breath. A workers’ comp audit isn’t an interrogation—it’s simply an annual “check-up” to ensure you’re paying the right premium for your actual business operations.
What Is a Workers’ Comp Audit?
A workers’ compensation audit occurs at the end of the policy term to compare estimated payroll and employee classifications against actual numbers. When you first bought your policy, your insurer made educated guesses about your payroll and operations. The audit verifies your company’s payroll and ensures your premium accurately reflects your actual exposure.
What Happens During the Audit?
At the end of your policy period, the Premium Audit team will contact you to complete your audit online or in-person. The auditor will examine:
- Payroll Records: All compensation including overtime and bonuses
- Employee Classifications: Ensuring workers are properly categorized
- Subcontractor Information: Certificates of insurance and 1099s
- Business Operations: Confirming actual activities match your policy
Essential Documents Checklist
| Document Type | What You Need |
| Payroll Records | Payroll registers, journals, and summaries with correct job titles |
| Tax Documents | Federal 941 quarterly returns, state unemployment reports |
| Subcontractor Records | Certificates of insurance, 1099 forms, contracts |
| Financial Records | General ledger, cash disbursement records |
5 Pro Tips for Audit Success
1. Stay Organized Year-Round
Create separate folders for payroll records, subcontractor certificates, employee classifications, and financial statements. Don’t wait until audit time!
2. Keep Complete Payroll Records
Submit payroll reports timely and include all payroll during the reporting period. Additional payments like lodging, meals, car allowances, and uninsured subcontractor payments count as payroll.
3. Classify Employees Correctly
Incorrect employee classification can lead to significant premium changes during your audit. Match job descriptions to actual duties performed.
4. Maintain Subcontractor Documentation
Keep current certificates of insurance to help auditors distinguish between employee payroll and legitimate subcontractor expenses.
5. Designate a Contact Person
Assign a designated contact person who understands your payroll system and can efficiently provide information.
