Workers Compensation Insurance for General Contractors in Illinois: Coverage, Costs, and Requirements

Workers compensation insurance is required for Illinois general contractors with one or more employees. WC covers your employees' work-related injuries and illnesses: medical treatment, lost wages, disability benefits, and death benefits. Illinois has a robust WC system administered through the Illinois Workers Compensation Commission, and Chicago's construction market is one of the country's most active. Illinois GC WC premiums are above the national average.

Quick Answer

Estimated workers compensation premiums for Illinois general contractors:

Business Size	Estimated Annual WC Premium
Small GC (1 to 5 employees)	$2,000 to $4,000 per year
Larger GC (6 or more employees)	$3,800 to $7,600 per year

Illinois GC workers comp premiums are above the national average. Actual premiums depend on payroll, employee classification codes, and experience modification factor.

What Workers Comp Covers for Illinois General Contractors

Medical Treatment for Work Injuries

WC covers the cost of medical treatment for employees injured on the job -- emergency care, surgery, physical therapy, and ongoing treatment.

Lost Wages

WC pays a portion of an injured employee's wages during recovery. Illinois temporary disability benefit is two-thirds of average weekly wages up to a state maximum.

Permanent Disability

WC provides permanent partial and total disability benefits under Illinois's WC schedule.

Death Benefits

WC pays death benefits to eligible dependents of employees who die from work-related injuries or illnesses.

Employer's Liability

Workers comp policies include an employer's liability section that covers lawsuits from employees claiming negligence beyond the WC system.

What Workers Comp Does Not Cover for Illinois General Contractors

Subcontractor Injuries

WC covers your employees, not independent subcontractors. Subcontractors need their own WC. Uninsured subcontractor payroll may be added to your policy at audit. Collect WC certificates from every subcontractor before work begins.

Third-Party Bodily Injury

WC does not cover bodily injury claims from non-employees. General liability covers those third-party claims.

Property Damage

WC does not cover property damage. GL covers property damage claims.

Illinois-Specific Considerations

Illinois Workers Compensation Commission

Illinois WC disputes are adjudicated by the Illinois Workers Compensation Commission (IWCC). Illinois is known for a worker-favorable WC system, contributing to above-average premiums. GCs should maintain strong injury prevention programs to control claims frequency.

Chicago Construction Market

Chicago is one of the country's largest construction markets. Illinois GCs working on commercial, residential, and infrastructure projects in Chicago and the surrounding metro operate in a high-volume, high-scrutiny market. Project owners, lenders, and general contractors on public projects routinely require WC certificates.

BIPA and Workplace Systems

Illinois's Biometric Information Privacy Act (BIPA) restricts biometric data collection. GCs that use fingerprint-based time tracking or biometric site access systems for employees face BIPA exposure. WC does not cover BIPA claims.

Subcontractor Certificate Management

Illinois GCs should maintain current WC certificates for every subcontractor on every project. At audit, uninsured sub payroll is added to your policy at the applicable construction classification rate.
