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.

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?
