Frequently Asked Questions

1. How much will I receive in Illinois workers' comp?

Temporary total disability pays 66.67% of your average weekly wage, up to approximately $1,700+/week (2026 maximum, adjusted annually). Permanent partial disability is 60% of AWW for duration determined by severity.

2. How long do I have to file a claim in Illinois?

3 years from the date of injury—the longest statute of limitations in the nation. For occupational diseases, 3 years from disablement or date you knew/should have known it was work-related.

3. Can I choose my own doctor?

You select from your employer's approved provider list. You can petition the IWCC for an outside doctor if necessary treatment isn't available on the list.

4. How is permanent disability calculated in Illinois?

Illinois uses a "man as a whole" approach considering age, occupation, education, physical impairment, and impact on earning capacity. Arbitrators have discretion, often resulting in higher awards than strict impairment rating states.

File with the IWCC. Benefits may be paid through the Illinois Workers' Compensation Commission's enforcement division. Your employer faces penalties and criminal charges.

No. Illinois prohibits retaliation for filing claims. You can seek reinstatement, back pay, damages, and attorney's fees if fired for filing.

File an Application for Adjustment of Claim with the IWCC. Your case will go to arbitration where you'll present medical evidence and testimony before an arbitrator.

From filing to trial: typically 12-24 months. Settlement negotiations can resolve cases faster. Complex cases may take longer.
