How Long Does an Employee Have to File for Worker’s Comp in Illinois?

If you get hurt on the job in Illinois, you need to act fast. Workers’ compensation covers medical bills and lost wages for job-related injuries or illnesses – but strict deadlines apply. Missing those deadlines could cost you your benefits, leaving you without the support you need. Do not wait to protect your rights and your recovery.

Reporting the Injury to Your Employer

The first step in pursuing a workers’ compensation claim is reporting your injury to your employer. Illinois law gives you 45 days from the accident date to provide notice. While verbal notice is allowed, written documentation is strongly recommended to protect your claim.

For injuries that develop over time – such as carpal tunnel syndrome, back pain, or other repetitive strain injuries – you have 45 days from the date you knew (or reasonably should have known) that the condition was work-related. If you miss this reporting deadline, your employer could deny your claim entirely, leaving you without coverage or compensation.

Filing a Workers’ Compensation Claim

In addition to reporting the injury to your employer, you must also file a claim with the Illinois Workers’ Compensation Commission (IWCC). This is called an Application for Adjustment of Claim. The deadline for filing with the IWCC is three years from the date of injury or two years from the date you last received benefits, whichever is later.

So, if you were receiving workers’ comp payments that stopped, you still have two years from your last payment to formally file a claim. You can find these deadlines outlined in the Illinois Workers’ Compensation Handbook.

Exceptions That May Apply

Some situations may extend or shift the usual workers’ compensation deadlines. For instance, occupational diseases – like those caused by prolonged chemical exposure – follow a different timeline. In these cases, the clock starts when you become aware of the illness and its link to your job.

Radiation exposure cases are another exception, requiring notice within 90 days of when you knew or reasonably should have known about the exposure.

Regardless of the type of injury or illness, delaying action can seriously damage your claim. The longer you wait, the harder it may be to prove your case or access the benefits you deserve.
