What Is a Workers' Compensation Class Code?
In workers' compensation, a class code is a two‑digit number that identifies the type of work performed by employees. It determines the premium rate the employer pays and the benefits available if an injury occurs. The code is set by the state insurance regulator and reflects the inherent risk of the occupation.

When Do Owners Need a Class Code?
Business owners who hire employees and pay wages are required to carry workers' compensation insurance. Even if the owner does not claim benefits, the policy covers all employees and the owner's payroll. The owner must still list a class code when applying for coverage because the insurer uses it to calculate the overall risk profile of the company.
Common Class Codes for Small Business Owners
Owners in different industries typically fall into one of several common codes. Below is a quick reference for the most frequently encountered categories:
| Class Code | Typical Occupation | Risk Level |
|---|---|---|
| 01 | Manufacturing – heavy machinery | High |
| 05 | Construction – general labor | High |
| 15 | Office clerks | Low |
| 22 | Retail sales | Low |
| 30 | Information technology | Low |
How to Identify the Correct Code for Your Business
Follow these steps to ensure accurate classification:
- Review the state's workers' comp manual or online database for the official list of codes.
- Match the majority of your employees' duties to the most representative code.
- Consult with your insurance broker or a certified payroll specialist if the job functions are mixed.
Special Cases
If your business performs multiple distinct activities—such as a retail store that also offers in‑store repairs—you may need to file a combined rate. Some states allow separate class codes for each activity, which can increase premiums but reduce liability for lower‑risk tasks.
Implications of Misclassification
Incorrect class codes can have serious consequences:
- Under‑rated codes may lead to higher rates if the insurer discovers the true risk later.
- Over‑rated codes may result in unnecessarily high premiums.
- Incorrect codes can delay or deny claims if the insurer disputes the classification.
Filing and Reporting Requirements
When you file a new policy, provide:
- The class code for each employee category.
- Payroll reports that match the code to wages paid.
- Any changes in job duties that affect the code.
State regulations often require quarterly or annual updates. Failure to keep records current can trigger penalties or loss of coverage.
