Workers' compensation insurance is an essential safeguard for businesses, protecting both employers and employees when workplace injuries occur. However, many business owners are surprised to receive a higher-than-expected bill after their workers' compensation audit.
If you've ever wondered why your premium changed after the policy period ended, you're not alone. Understanding how workers' compensation audits work can help you avoid unexpected premium increases and keep your business financially prepared.
A workers' compensation audit is a review conducted by your insurance carrier at the end of a policy term. The purpose is to verify that the payroll estimates and employee classifications used to calculate your premium accurately reflect your actual business operations during the policy period.
When you purchase workers' compensation insurance, your premium is based on estimated payroll figures. Since payroll often changes throughout the year, insurers conduct audits to compare estimated figures with actual payroll records.
If your actual payroll is higher than estimated or employees were assigned to incorrect job classifications, you may owe additional premium. If your payroll was lower than estimated, you may receive a refund.
Workers' compensation premiums are directly tied to your business's level of risk and payroll exposure. The audit helps ensure that businesses pay the correct premium based on their actual operations.
A workers' compensation audit can affect:
Understanding the process can help you avoid surprises and identify opportunities to control insurance costs.
One of the most common reasons for a premium increase is business growth.
If your company hired additional employees, increased wages, paid overtime, or expanded operations during the policy period, your actual payroll may exceed the original estimate.
Since workers' compensation premiums are largely based on payroll, higher payroll often results in higher premiums.
Different job roles carry different levels of risk.
For example, an office administrator generally has a lower workers' compensation rate than a construction worker. If employees are assigned to incorrect classification codes, the audit may adjust those classifications and increase your premium.
Proper employee classification is one of the most effective ways to prevent audit surprises.
Auditors rely on documentation to verify payroll and employee duties.
If payroll reports, tax records, subcontractor certificates of insurance, or employee records are incomplete, the auditor may assign higher-risk classifications by default, resulting in additional premium charges.
Many businesses, particularly contractors, use subcontractors to complete projects.
If a subcontractor does not carry their own workers' compensation coverage and you cannot provide proof of insurance, your insurer may include those labor costs in your payroll calculations during the audit.
This can significantly increase your premium.
Preparation is the key to a smooth audit process.
Maintain detailed payroll reports throughout the year, including:
Accurate documentation makes it easier to verify payroll figures and reduce the risk of disputes.
As employees take on new responsibilities, their job classifications may need updating.
Conduct periodic reviews to ensure each employee is assigned the appropriate workers' compensation classification code.
If you work with subcontractors, collect and store current certificates of insurance before work begins.
This simple step can help prevent subcontractor costs from being added to your payroll during an audit.
Major business changes such as hiring additional staff, opening new locations, or expanding services should be discussed with your insurance professional as soon as possible.
Proactive communication can help avoid large premium adjustments at audit time.
