Workers’ compensation insurance is essential for safeguarding both employees and employers when workplace injuries occur, but it also comes with strict rules and detailed reporting requirements. Since regulations differ from state to state and the coverage involves sensitive financial and legal obligations, even small mistakes can create major complications for a business.
That’s why preparing for a workers’ compensation audit matters. These audits verify accurate payroll data, job classifications and coverage details. Without the right processes in place, they can quickly become overwhelming for human resource teams. A thoughtful, organized approach not only keeps you compliant but also helps prevent unexpected costs and administrative stress.
What is a Worker’s Compensation Audit?
A workers’ compensation audit occurs annually, whenever the policy term expires. What occurs is a systematic review of your records, to ensure you have paid the right amount over the last policy term. Your insurance carrier will go over your premium payments and compare them to the estimates you provided at the start of the policy period. The goal is to ensure your payments accurately reflect your payroll costs and level of risk.
Audits review your payroll data to confirm your premiums accurately reflect the total compensation paid to employees over the policy term, including both wages and benefits. Premiums are also influenced by job classifications, which indicate the level of risk associated with different roles. Since these factors directly affect coverage and cost, most states require insurers to audit a large portion, if not all, of their policies annually. In many states, these audits are a legal obligation for employers.
What Occurs During an Audit?
The audit process begins with a communication notifying you that your premium audit is due within a certain timeframe. In most cases, this is done via email. You will review your payroll and other expenses in detail and compare them to your original estimates. There are several reasons your projected numbers may have changed over the year, including:
- Rapid business growth and hiring.
- Unplanned layoffs.
- Voluntary turnover.
- Misclassification of employees and their risk levels.
- Clerical errors, including failure to include deductions.
Depending on your insurance carrier, the audit may take place via phone, online or in person. These audits are not done at random but are mandatory when you have a workers’ compensation policy. If your policy gets canceled, a premium audit will likely happen for the policy period in which you had coverage.
Documenting Workers’ Compensation
The exact type of documentation you are to provide is dependent on your location, insurer, industry and business size. When you first open your business insurance policy, ensure you understand what documentation you need to provide at the upcoming audit. Most workers’ compensation audits include a review of:
- Financial records, such as the business’s profit & loss statement.
- Payroll records.
- Tax forms such as W-2s, 1099s, Form 941 and Form 944.
- Federal tax returns.
- Certificates of insurance for every subcontractor.
- Detailed descriptions of each business function, including each employee’s risk level at work.
Audit Results
At the conclusion of the audit, you’ll receive a report outlining whether you owe an additional premium or are entitled to a refund, depending on whether your actual payroll and classifications resulted in a variance. If the audit shows that you underpaid, you’ll be billed for the difference. If you overpaid, your insurer would issue a refund. Once the report arrives, take time to review it carefully, and if any findings appear inaccurate or unclear, reach out to your insurer right away so they can guide you through the process of filing a formal dispute.
