Illinois Insurance Requirements for Contractors
Workers' Compensation in Illinois
Illinois requires workers' compensation insurance for all businesses with 1 or more employees. The Illinois Department of Insurance enforces compliance, and penalties for operating without coverage include fines of up to $1,000 per day and potential criminal charges. For contractors with the inherent physical risks of the trade, WC is both a legal requirement and a business necessity.
General Liability Requirements
While Illinois doesn't set a state minimum for general liability coverage, the practical reality is different. Most commercial landlords in Chicago and other IL metros require $1,000,000 in GL coverage before signing a lease. For contractors, clients will almost certainly require a Certificate of Insurance (COI) before awarding contracts.
