In Connecticut, workers' compensation premiums are driven by an established rate table that assigns classification codes to industries and sets base rates per $100 of payroll. This guide explains how the Connecticut workers' compensation rate table is structured, how premiums are calculated, what experience rating does, and how employers can ensure accurate reporting. Because rates and rules can change, always confirm current numbers with the Connecticut Workers' Compensation Insurance Rating Bureau (CWCRB) or your broker.

How the Connecticut Rate Table Works
The Connecticut workers' compensation rate table matches industry classifications with base rates and loss costs. Insurers apply these rates to your payroll to determine premium. Key inputs include classification code(s), total payroll, and, for many policies, your experience modification factor (mod). Understanding these relationships helps employers anticipate costs and manage risk.
Classification Codes
Each business is assigned one or more classification codes that reflect job duties and risks. Common codes include clerical, light manufacturing, and construction. The table lists each code with a base rate per $100 of payroll. Selecting the correct code is essential; misclassification can lead to audits, penalties, or premium inaccuracies.
Premium Calculation
Premium is typically calculated as (payroll ÷ 100) × rate. For example, if the rate for a code is $2.50 per $100 of payroll and payroll exposed is $100,000, the base premium would be $2,500 before discounts or the mod. Additional endorsements, medical-only coverage, or prospective rating endorsements can adjust the premium. The Connecticut workers' compensation rate table serves as the starting point; endorsements and policy terms shift the final cost.
| Attribute | Verified Detail | Source Type |
|---|---|---|

| Audit Frequency | Policies often audited annually to reconcile estimated vs. actual payroll | Standard policy terms |
| Rating Bureau | Connecticut Workers' Compensation Insurance Rating Bureau (CWCRB) | Official rate and data source |
Experience Rating in Connecticut
Many workers' compensation policies in Connecticut are experience-rated, meaning your mod can lower or raise your premium based on past losses. A mod below 1.0 reduces premium; above 1.0 increases it. Employers with strong loss control can benefit from lower mods, while frequent claims can increase costs. The rate table provides the base; the mod adjusts it based on your history.
Practical Steps for Employers
- Confirm classification codes annually and ensure they match actual job duties.
- Report payroll changes promptly to avoid mid-term audit adjustments.
- Monitor loss experience and implement safety programs to reduce incident rates.
- Review policy endorsements to verify they align with exposure.
- Work with a broker familiar with Connecticut workers' compensation to interpret the rate table and market options.
Common Questions
Small misclassifications might not trigger immediate penalties, but consistent or significant errors can lead to audits, premium reassessments, and interest. Payroll definitions vary by policy; some include certain benefits or subcontract costs. Not all policies carry experience mods—small eligible employers may be classified as small employer plans with different rules. Check with your carrier or broker for specifics that apply to your account.
Staying current on classification guidance and maintaining accurate payroll records are the best ways to manage workers' compensation costs in Connecticut. Use the Connecticut workers' compensation rate table as a baseline, and confirm figures with official sources and your insurance professional for your unique situation.
