What the Illinois Workers Comp Board Does

Chicago hearings are held at the Daley Center (50 W. Washington, LL-17); other offices are in Springfield, Collinsville, Peoria and Rockford — call before visiting Peoria or Rockford. Arbitrators hear disputes; appeals go to a panel of commissioners, then the circuit court.

Three things the Illinois workers comp board does not do: it does not pay most claims (the employer’s insurer does, unless the state runs the fund), it does not give legal advice, and it does not choose a doctor for you. It is the referee and the record-keeper, which is exactly why its information line is the first free call for a confused claimant.

The Illinois Workers Comp Board for Injured Workers

Report the injury to your employer first — that deadline is set by Illinois law, not by the agency. Then the Illinois workers comp board comes in at three points: filing the worker’s claim form when the employer or insurer will not act, requesting a hearing when a claim is denied or benefits stop, and approving any settlement before it is final.

Bring the claim number, the date of injury, the insurer’s name and every letter you have received. Our Illinois claim guide walks through the deadlines and forms before you make the call.

The Illinois Workers Comp Board for Employers

Employers meet the Illinois workers comp board when they prove coverage, file the first report of injury after an accident, post the required notice in the workplace and — if they qualify — file an exemption. Coverage is bought from a private insurer or the assigned-risk plan; the agency checks that it exists. The threshold and penalties are in our Illinois requirements guide.

Illinois Workers Comp Board Coverage Lookup, Forms and Poster

The agency publishes a coverage-verification lookup on its site so a worker, a contractor or a client can confirm an employer is insured; start from the homepage above. Forms are at the official forms page. The required workplace poster is free from the agency — the companies selling it are selling a free document.

Before You Call the Illinois Workers Comp Board

Agency lines are busiest Monday mornings and the first days of the month. Have the claim number ready, ask for the name of the person you spoke with, and follow up in writing. The Illinois workers comp board can explain the process and the deadlines, confirm whether a form was received and tell you how to request a hearing; it cannot tell you what your case is worth.

For that question, our Illinois settlement guide and a licensed attorney are the next stops.

District and hearing offices: larger states hear cases at regional offices rather than at headquarters. Where Illinois has them, they are listed on the agency site under locations, and the hearing notice names the office for your case.
