Illinois Workers' Comp Exemption

Sole proprietors are not automatically covered. Under 820 ILCS 305/1(b), every sole proprietor and every partner of a business may elect to be covered — meaning the default is exclusion, and coverage requires an affirmative opt-in. Doing nothing simply leaves them excluded.

LLC members are treated the same as sole proprietors and partners under 820 ILCS 305/3 — elective coverage, with no numeric cap found on how many can be excluded. The major exception is "extra-hazardous" businesses (which includes construction) under 820 ILCS 305/3: partners and LLC members in these businesses are automatically covered by default and must affirmatively opt out via written notice to the insurance carrier, with a copy attached to the insurance application.

A corporate officer may individually elect to withdraw from coverage via written notice to the insurance carrier under 820 ILCS 305/1, effective when the carrier receives it. Illinois defines "corporate officer" narrowly for this purpose — only President, Vice President, Secretary, or Treasurer qualify, confirmed on both the statute and NCCI's Illinois state instructions. We found no verifiable numeric cap on how many officers can withdraw. Officers and directors of publicly traded corporations are explicitly barred from using this withdrawal election. Extra-hazardous businesses flip the default the same way as for partners and LLC members — automatic coverage, with an opt-out required.

Illinois is distinctive here: the IWCC explicitly states it has no opt-out form. The election — whether opting in or opting out — is made by written notice sent directly to the insurance carrier, not filed with any state agency. For assigned-risk/residual-market employers, a copy must be attached to the ACORD insurance application. There's no state filing fee, since nothing is actually filed with the state. We found no confirmed renewal requirement; the election appears to remain in effect until affirmatively revoked by new written notice, though no primary source explicitly states "no renewal is ever required," so treat that as a general pattern rather than a guarantee.

The extra-hazardous/construction flip is the standout feature of Illinois's system: ordinary businesses default to excluded/opt-in, while extra-hazardous businesses default to covered/opt-out. Illinois is also one of the few states with no state-issued opt-out form at all — everything runs through private carrier notice rather than a government filing. Penalties for uninsured employers are steep: up to $500 per day (with a $10,000 minimum) for willful violations, personal officer liability, and potential criminal exposure ranging from a Class A misdemeanor to a Class 4 felony.
