The Purpose of the Workers Compensation Premium Audit
When a business owner purchases a Workers Compensation policy, the initial premium paid is almost always an estimate. Because Workers Compensation premiums are based on payroll (remuneration), and payroll fluctuates as employees are hired, terminated, or given raises, the insurance company cannot know the exact exposure at the start of the policy term. For more foundational information on how these policies are structured, refer to our complete Workers Comp exam guide.
The premium audit is a formal review of the employer's records to determine the actual exposure that existed during the policy period. The primary goal is to ensure that the premium collected by the insurer accurately reflects the risk assumed. If the actual payroll was higher than the estimate, the insured owes an additional premium. If the payroll was lower, the insured may receive a refund or credit. This process is a standard contractual right granted to the insurer under the policy terms.
Estimated Premium vs. Final Audited Premium
| Feature | Estimated Premium (Deposit) | Final Audited Premium |
|---|---|---|
| Timing | Calculated at policy inception | Calculated after policy expiration |
| Basis | Projected payroll for the upcoming year | Actual remuneration paid to employees |
| Purpose | To establish a deposit and billing schedule | To reconcile actual risk and close the policy |
| Adjustments | N/A | Results in additional premium or refund |
Defining Remuneration: What the Auditor Looks For
The term remuneration is the technical word for the payroll used to calculate the premium. It is not limited to just base hourly wages or salaries. To pass the Workers Compensation exam, you must understand that the auditor is looking for the total value provided to employees for their services.
Common items included in remuneration are:
- Gross wages and salaries
- Commissions and bonuses
- Overtime (usually calculated at the straight-time rate for audit purposes)
- Pay for holidays, vacations, and sick leave
- The value of lodging or meals provided as part of pay
- Employee contributions to 401(k) or other retirement plans
Conversely, certain items are generally excluded from the audit calculation, such as tips, employer contributions to group insurance plans, and severance pay. Understanding these nuances is critical when preparing for practice Workers Comp questions.
Key Audit Figures and Factors
Types of Premium Audits
Not every audit involves an insurance professional visiting the place of business. The method used often depends on the size of the premium, the complexity of the business, and the insurer's internal guidelines.
- Mail Audit: Often used for smaller businesses with low-risk classifications. The insured receives a form to fill out and returns it with supporting documentation like tax filings.
- Phone Audit: A representative from the insurance company calls the business owner or accountant to verify payroll figures and employee duties over the phone.
- Physical Audit: An auditor visits the business location to review books, records, and observe operations. This is common for larger accounts or high-risk industries like construction.
- Virtual Audit: A modern hybrid approach where the auditor reviews digital records through a secure portal and conducts interviews via video conferencing.
The Importance of Job Classifications
The Final Calculation and Experience Modification
Once the auditor determines the final payroll for each class code, the premium is recalculated using the following formula:
(Actual Payroll / 100) x Manual Rate x Experience Modification Factor = Final Premium
The Experience Modification Factor (E-Mod) is a multiplier that adjusts the premium based on the employer's past loss history compared to others in the same industry. If the business had fewer claims than expected, the E-Mod will be below 1.0 (a credit). If they had more claims, it will be above 1.0 (a debit). The audit ensures that this factor is applied to the actual payroll rather than just the estimate.
Frequently Asked Questions
Most policies include an 'Audit Non-Compliance Charge.' If the insured refuses to provide records, the insurer can charge a significant penalty (often double the estimated premium) and may cancel the policy or refuse to renew it.
Under the standard Workers Compensation and Employers Liability policy, the insurer has the right to examine and audit the insured's records at any time during the policy period and within three years after the policy period expires.
Yes, if a subcontractor does not have their own Workers Compensation insurance, the primary contractor's insurer will charge a premium for them. Auditors will ask for Certificates of Insurance (COIs) from all subcontractors to prove they are covered elsewhere.
Absolutely. If the business downsized or payroll was lower than projected, the audit will show that the insured overpaid their deposit, resulting in a return premium or a credit toward the next policy term.
