What is workers compensation insurance and when is it required?

Understanding Workers' Compensation Insurance in Connecticut

Workers' compensation insurance provides coverage for employees who suffer work-related injuries or illnesses. It helps cover medical expenses, rehabilitation costs, and lost wages, protecting both employees and employers from financial risk.

When Is Workers' Compensation Insurance Required in Connecticut?

As of 2026, Connecticut law mandates that most employers with one or more employees must carry workers' compensation insurance. This includes full-time, part-time, and seasonal workers. The requirement applies to:

• Businesses with one or more employees, including family members employed in the business
• Construction contractors and subcontractors regardless of the number of employees
• Employers who lease employees through staffing agencies

Businesses without employees, such as sole proprietors or independent contractors, are generally not required to carry workers' compensation insurance but may choose to do so voluntarily.

Operational Considerations for Connecticut Employers

• Business registration: Ensure your business is properly registered with the Connecticut Department of Labor to comply with insurance reporting requirements.
• Insurance procurement: Obtain workers' compensation insurance through a licensed insurer or the state’s assigned risk pool if coverage is denied by private insurers.
• Payroll integration: Accurately classify employees and integrate workers' compensation premiums into payroll systems to ensure proper premium calculation and recordkeeping.
• Employee classification: Correctly classify employees versus independent contractors to avoid coverage gaps and compliance issues.
• Claims management: Establish procedures for timely injury reporting and claims filing to minimize disruptions and maintain compliance.
• Compliance monitoring: Regularly review insurance coverage and payroll records to ensure ongoing compliance with state requirements.

Failing to maintain required workers' compensation insurance can result in penalties, fines, and potential business license suspension. Integrating workers' compensation insurance management with overall compliance and payroll processes supports smoother operations and risk mitigation.
