An Illinois corporation with employees must carry workers' comp from its first hire (820 ILCS 305/3), and corporate officers are treated as covered persons who may exempt themselves. So your regular employees are always covered, and an officer comes off the policy only by notifying the carrier in writing to exempt out (820 ILCS 305/1). The corporate form does not change the coverage duty; it only changes who among the owners can be left off.
Who this is for: owners and officers of Illinois C-corporations and S-corporations, with or without other staff.
The short version
- A corporation with any employee must carry a policy, and its regular employees are always covered.
- Corporate officers are covered by default and may exempt themselves by written notice to the carrier (820 ILCS 305/1).
- Exempting officers out does not affect your employees; they cannot be excluded.
- If the corporation goes uninsured, officers and directors can face a felony and personal liability (820 ILCS 305/4).
- That personal exposure does not apply to an officer or director of a publicly-owned corporation.
How Illinois treats corporate officers
Illinois does not automatically leave corporate officers off the policy. The Commission lists corporate officers among the owners who may exempt themselves from coverage, but who must still purchase insurance for other employees and notify the carrier in writing when they exempt out. So an officer is inside the policy by default and has to take an affirmative step to come off. There is no state exemption registry; the mechanism is the carrier endorsement plus written notice. A small closely held corporation and a large one follow the same rule, but the personal-liability consequences below differ for a publicly-owned corporation.
What applies to your corporation
| Your corporation setup | Is comp required? | What owners and staff should know |
|---|---|---|
| Officers only, no other employees | Depends on the work | Officers are covered by default; each may exempt out with written notice |
| Any non-officer employees | Yes | Employees covered from the first hire; officers may still exempt themselves |
| Closely held corporation | Yes, if it has employees | Officers can exempt out; they remain personally exposed if the company goes uninsured |
| Publicly-owned corporation | Yes, if it has employees | Officers and directors are not subject to the Act's criminal and personal-liability provisions |
The personal-liability catch
Incorporating shields your personal assets from many business debts, but it does not shield you from an uninsured comp claim. If an Illinois corporation that was required to carry coverage knowingly goes without it, an individual officer or director is guilty of a Class 4 felony, and doing so negligently is a Class A misdemeanor, with each day a separate offense (820 ILCS 305/4). An uninsured employer also loses the legal protection that normally keeps an injured worker from suing, and loses the usual defenses in that lawsuit. The one exception is that these criminal and personal-liability provisions do not reach an officer or director of a publicly-owned corporation.
A Rockford example
Illustrative, not a quote. A Rockford heating and cooling company is set up as an S-corporation with two officer-owners and four installers. Because the business has employees, Illinois requires a policy and the installers are covered from day one. Each officer is on the policy by default and can notify the carrier in writing to exempt out; if they do not, they stay covered. We place the policy, rate the installation payroll correctly, and confirm the officer elections are recorded with the carrier. See our workers comp for HVAC contractors page.
Real questions Illinois owners ask
Does my Illinois corporation need workers comp?
Yes, once it has employees. A corporation must carry coverage from its first hire, and officers count as covered persons unless they exempt themselves out.
Are corporate officers covered by workers comp in Illinois?
By default, yes. An officer is treated as a covered person and stays on the policy unless they notify the carrier in writing to exempt out.
Can a corporate officer opt out of coverage?
Yes. An officer may exempt themselves by written notice to the carrier, but the corporation must still insure its other employees, who cannot be excluded.
If my officers exempt out, are the employees still covered?
Yes. An officer exemption only affects that officer. Every non-officer employee remains fully covered and cannot be excluded.
Can I be personally liable if the corporation has no coverage?
Yes. If a corporation that was required to carry coverage goes uninsured, its officers and directors can face felony or misdemeanor charges and personal liability, except at a publicly-owned corporation.
Does the publicly-owned exception apply to my small company?
Almost certainly not. The exception is for officers and directors of a publicly-owned corporation. A closely held small company does not get it, so its officers stay personally exposed.
Why Illinois owners choose Morrow
- We shop the right market for you. In Illinois you buy workers' comp on the open market from any private carrier licensed in the state, because Illinois has no state fund; if no carrier will take you, the Illinois Workers' Compensation Assigned Risk Plan (the assigned-risk plan) is the guaranteed fallback, so we can shop your rate freely and still keep a backstop for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
