The threshold language matters: states write the rule slightly differently. Some count any worker, some count only W-2 employees, some count owners separately, some have industry-specific exemptions (agriculture, domestic service, casual labor). For a Illinois employer with a non-trivial workforce, the safest default is: assume coverage is required and confirm with the state department of insurance or a local agent.
How the threshold interacts with 1099s and subs
Illinois uses a multi-factor test to determine if a 1099 contractor is an employee for workers' compensation purposes. General contractors are liable for the workers' compensation coverage of uninsured subcontractors.
Penalty for going without
Fines up to $10,000 per day of non-compliance, potential imprisonment, and personal liability for all claim costs. The financial penalty is usually a fraction of the human cost: an injured employee at an uncovered employer can sue directly under tort law instead of being limited to the workers comp benefit, exposing the owner to lost-wage damages, pain and suffering, and punitive damages without the corporate veil.
