Illinois — what makes it different

Illinois has one of the highest maximum benefits and most generous PPD schedules. Strong claimant jurisdiction.

Real example: how the Illinois cap works

A worker earning $3796/week in Illinois (above-average wage):

Raw formula: $3796 × 66.67% = $2530.69/week
Illinois cap kicks in: $1897.92/week
Effective replacement rate: 50.0% of pre-injury wage (not 66.67%)

For a 26-week disability, that's $49,346 in total TTD benefits — substantially less than what 66.67% of full wage would pay.

If a third party contributed to the injury, the difference between full wage and capped benefit becomes part of a separate third-party personal injury claim.
