Roman Empire Insurance Agency · Published
A workers’ compensation audit review can reduce an overstated bill when the records support a correction. The starting point is finding out why the carrier charged more. More payroll, changed operations, or a valid classification adjustment can explain an increase. A payroll error or an unsupported assignment can also affect the result. A review tests the calculation against the records; the savings, if any, depend on what that review finds.
Roman Empire Insurance Agency helps California business owners prepare for audits and understand additional premium bills. Our Burbank team can review the records behind the result and discuss supported questions with the carrier. Start with our workers’ comp audit help page.
Why did the carrier send another bill?
Your policy begins with estimated payroll. The final audit compares that estimate with actual payroll and operations for the policy period. The California Department of Insurance explains that a higher actual payroll can produce additional premium, while a lower payroll can produce return premium. An unexpected bill is a reason to check the details, rather than assume it is automatically wrong.
What does our team look at?
- The payroll period and totals. We compare the audit dates and payroll figures with the records you provide, looking for differences that need an explanation.
- Overtime and other pay items. Certain items have specific treatment under California’s rules. For example, the extra overtime premium may be excluded when the required records support it; the regular-pay portion remains included. Read our overtime audit example.
- Classifications and actual work. A job title alone does not settle every classification question. We discuss your operations and compare the assigned classes with the applicable rules. Separating payroll between classes requires suitable records and must be allowed by those rules.
- The policy calculation. We compare the audit breakdown with the policy’s rates and applicable rating factors, including the experience modification when one applies.
These checks identify questions to resolve. They do not mean every item is deductible or that a different class code is available to every business.
How can a correction lower the bill?
If the carrier agrees that payroll was overstated, an allowed adjustment was missed, or a classification was applied incorrectly, it can recalculate the premium using the corrected information. A well-supported request points to the exact entry, the applicable rule, and the records that explain the difference. A correct audit may remain unchanged, and the review may also uncover information that increases the amount due.
The amount of any reduction depends on the error, the policy calculation, and the carrier’s decision. A lower additional audit bill is also different from a lower total annual premium. Compare both figures when evaluating a result.
Bring us the bill and the explanation behind it
Start with the policy period, audit notice or final bill, deadline, and a brief description of what seems wrong. We can then discuss the payroll summaries, job descriptions, and other records needed for a review. Keep sensitive employee files out of the first email; our team can arrange an appropriate way to exchange documents.
Contact us promptly if you disagree with the calculation. Ask the carrier about its review process and applicable deadlines, and obtain written instructions about payments while a question is being reviewed. Do not assume that a dispute automatically pauses the bill.
