How Connecticut Sets Workers' Compensation Class Code Rates
Connecticut's Department of Labor assigns each occupation a class code that reflects its injury risk. Premiums are calculated by multiplying the employer's payroll in that class by a state‑determined rate per $100 of payroll. Rates are adjusted annually based on the state's loss experience, medical cost trends, and the insurer's experience modification factor (mod). Because the mod reflects an employer's own claim history, two businesses with identical payrolls can pay different premiums.

Major Class Code Groups in Connecticut
While there are hundreds of specific codes, most employers fall into a handful of broad categories. Understanding where your business fits helps you anticipate rate changes and target safety improvements.
| Broad Category | Typical Class Codes | Risk Level |
|---|---|---|
| Construction | 5400‑5499 | High |
| Healthcare | 8800‑8899 | Moderate‑High |
| Office/Administrative | 8810‑8899 | Low |
| Retail | 8800‑8899 | Moderate |
| Manufacturing | 5400‑5499 | Variable |
Factors That Influence Your Specific Rate
Beyond the base class code, three main factors affect the final premium:
- Experience Modification (Mod): A numeric factor derived from your claim history compared to industry averages. A mod below 1.0 reduces premiums; above 1.0 increases them.
- Payroll Size: Larger payrolls spread fixed administrative costs, often resulting in a lower effective rate per employee.
- Safety Programs: Participation in state‑approved safety initiatives can qualify for discounts or lower class codes.
Strategies to Manage and Lower Rates
Employers can take proactive steps to keep premiums manageable:
- Conduct regular safety audits and train staff on injury‑prevention best practices.
- File accurate, timely claims and work closely with claims adjusters to mitigate loss costs.
- Consider consolidating multiple low‑risk jobs under a single, lower‑rate class code after confirming eligibility with the insurer.
- Review your mod annually and challenge any erroneous claim data that could inflate it.
Where to Find Updated Rate Tables
The Connecticut Department of Labor publishes the official workers' compensation rate schedule each July. Insurers also provide online portals where policyholders can view their current rates, mod, and any upcoming adjustments. Checking both sources ensures you have the most current information for budgeting and compliance.
