What are the ramifications of operating a business in Illinois without Workers’ Compensation insurance?
Here is a piece from the Illinois Workers’ Compensation Commission that addresses the subject.
Workers' Compensation Insurance: It's the LAW.
Illinois law requires employers to provide workers' compensation insurance for almost everyone who is hired, injured, or whose employment is localized in Illinois. Sole proprietors, business partners, corporate officers, and members of limited liability companies may exempt themselves. Overall, it is estimated that 91% of Illinois employees are covered under the Act.
An employer that knowingly and willfully fails to obtain insurance may be fined up to $500 for every day of noncompliance, with a minimum fine of $10,000. Corporate officers can be held personally liable if the company fails to pay the penalty. Since 2006, the Commission has collected over $7 million in fines!
