Workers comp carriers audit your payroll after every policy period. When actual payroll exceeds estimates — or auditors misclassify your workers — you face unexpected premium bills that can reach tens of thousands of dollars. Audit protection coverage defends your business and pays the difference.

Audit Defense Included
Dispute representation + premium coverage
Workers compensation premiums are calculated as a rate per $100 of payroll, multiplied by your experience modification rate (EMR) and applicable class codes. Because you don't know your exact year-end payroll at policy inception, carriers charge an estimated premium based on projected payroll figures.
At policy expiration — typically 60 to 90 days after the policy period ends — the carrier conducts a final payroll audit. They review your actual payroll records, verify class code assignments for each employee type, and reconcile subcontractor payments against certificates of insurance you collected.
If the audit reveals you underpaid — because payroll grew, workers were reclassified into higher-rated codes, or subcontractor payments were added to your payroll — you receive an audit bill. These bills can range from a few hundred dollars to hundreds of thousands for large employers. Audit protection coverage is designed to shield you from exactly this scenario.
Some businesses face routine annual audits; others are flagged for intensive investigation based on specific risk signals that carriers monitor throughout the policy period.
A large increase in actual vs. estimated payroll signals potential underreporting and routinely triggers a physical audit.
Adding workers in higher-hazard class codes than those on the original policy estimate prompts carrier re-evaluation.
Carriers scrutinize subcontractor certificates and uninsured sub payments, which can be added to your auditable payroll.
Businesses with prior audit findings are flagged for more frequent or intensive audits in subsequent policy years.
A claim filed by a worker whose class code doesn't match their job description triggers reclassification review.
Tips to state labor agencies about unreported workers or misclassification can initiate both state and carrier investigations.

When audit findings are inaccurate, you have defined rights to dispute them. Here's how a successful audit dispute unfolds — with CCA and your audit protection coverage in your corner.
Carrier sends audit notification — mail audit questionnaire or notice of physical audit visit. Typically issued 60–90 days after policy expiration.
Compile payroll journals, tax returns (940/941), certificates of insurance for all subcontractors, and any job classification documentation.
Analyze the auditor's report line by line — verify class codes assigned, payroll figures used, and subcontractor treatment.
Submit a written dispute with supporting documentation to the carrier's audit department. State specific objections with evidence.
Work with the carrier's audit review team to negotiate corrections. Many disputes resolve at this stage without formal appeal.
If the carrier dispute fails, escalate to the NCCI or state rating bureau for a formal classification determination.
