In Illinois, temporary total disability (TTD) benefits are paid at 67% of your average weekly wage, capped at $1,897 per week, for no statutory limit, administered by the Illinois Workers' Compensation Commission.
Temporary disability benefits in Illinois replace a portion of your income while you recover from a work injury and cannot work at your pre-injury capacity. There are two types: Temporary Total Disability (TTD) — paid when you are completely unable to work — and Temporary Partial Disability (TPD) — paid when you can work in a limited capacity but earn less than your pre-injury wage. In Illinois, the TTD rate is 67% of your average weekly wage (AWW), up to $1,897 per week, and can last no statutory limit.
TTD begins after the state's waiting period (typically 3–7 days) and continues until you return to work, reach Maximum Medical Improvement (MMI), or exhaust the state's maximum benefit period. At MMI, your treating physician will evaluate whether you have any permanent impairment and issue a rating. TPD pays 67% of the wage differential between your pre- and post-injury earnings, up to $1,897 per week.
Disputes about temporary disability benefits are common. Employers and insurers may challenge your treating physician's opinion with an Independent Medical Examination (IME) or argue that you have reached MMI before you believe you have. In Illinois, you have 30 days to challenge an insurer's decision to reduce or terminate temporary disability benefits by filing with the Illinois Workers' Compensation Commission.

Temporary Total Disability (TTD) in Illinois pays 67% of your AWW (up to $1,897/week) when you are completely unable to work. Temporary Partial Disability (TPD) pays 67% of the wage difference between your pre-injury and post-injury earnings when you can work in a limited capacity.
In Illinois, TTD benefits can last no statutory limit. Benefits end when you return to pre-injury work, reach Maximum Medical Improvement (MMI), or exhaust the maximum period. If you are approaching the maximum and still cannot work, consult an attorney immediately about permanent disability options.
Temporary disability in Illinois ends when: (1) you return to work at your pre-injury wage; (2) your physician declares Maximum Medical Improvement (MMI) — meaning further treatment won't meaningfully improve your condition; or (3) you reach the state's maximum TTD duration of no statutory limit. At MMI, your claim transitions from temporary to permanent status.
Generally no. Workers comp TTD benefits and unemployment insurance are mutually exclusive in most states. Unemployment insurance requires you to be able and available for work; TTD requires you to be unable to work. Receiving both simultaneously is considered fraud in Illinois and can result in repayment demands and criminal charges.
When TTD benefits exhaust in Illinois — either at Maximum Medical Improvement or the no statutory limit statutory limit — your claim transitions to permanent status. If you have permanent impairment, your physician rates it and you may receive a permanent partial disability (PPD) award. If you cannot return to any work, you may qualify for permanent total disability (PTD) or vocational rehabilitation.
Workers comp TTD and Social Security Disability Insurance (SSDI) are separate federal and state programs. You can apply for SSDI while receiving workers comp TTD, but an offset rule applies: combined workers comp and SSDI cannot exceed 80% of pre-injury average current earnings. If they do, Social Security reduces the SSDI payment — not your workers comp benefit.
