Who Needs Workers' Comp in Illinois?
Under state law, any business with one or more employees must carry a valid workers’ comp policy. This includes:
- Full-time, part-time, or seasonal workers
- Family members working for the business
- Corporate officers or LLC members (unless legally exempted)
Key exemptions include:
- Sole proprietors without employees
- Agricultural enterprises employing fewer than 400 total working days of labor per quarter during the preceding calendar year (excluding hours worked by the employer’s spouse and immediate family members residing with them)
However, most businesses—whether in Chicago, Springfield, or a small town—must comply. Violating workers’ comp compliance Illinois laws can lead to serious fines and even personal liability.
Illinois Workers' Comp Benefits: What's Covered?
A valid policy ensures that injured workers receive support quickly—without suing the employer. At the same time, it protects the business from unpredictable expenses tied to injuries.
Standard Illinois workers’ comp benefits include:
Medical coverage: Doctor visits, hospital stays, surgeries, prescriptions, rehab
Temporary Total Disability (TTD): Two-thirds (66⅔%) of average weekly wage during recovery
Permanent Disability: For partial or total long-term loss of ability to work
Vocational rehab: Retraining for new work if the old job is no longer possible
Death benefits: Funeral costs and income support for dependents
Example: A retail worker in Peoria injures their back stocking shelves. While recovering, their medical bills and lost wages are fully covered by the employer’s workers’ comp policy.
Common Claims Across Illinois Industries
Different industries face different risks, but certain claims are common across the state:
Overexertion injuries: Lifting heavy objects in construction, warehousing, or healthcare
Slip-and-fall accidents: Snowy or icy conditions during Illinois winters increase these risks statewide
Machine injuries: Manufacturing jobs near Rockford and Joliet see frequent claims from equipment use
Chemical exposure: Janitorial workers and lab techs often file respiratory or skin-related claims
Claims lasting more than 14 days are more frequent in Illinois than in many other states, which can increase costs for employers.
