If you're collecting unemployment in Illinois, filing your initial claim is only the first step. To keep receiving benefits, you must certify — a recurring process where you confirm your eligibility for each week you're claiming. Missing a certification, or answering questions incorrectly, can delay or interrupt your payments.
Here's how the Illinois certification process generally works and what to expect.
Certification (sometimes called a "weekly claim" or "bi-weekly claim") is the process of reporting to the Illinois Department of Employment Security (IDES) that you remain eligible for benefits during a given week. It's how the state confirms you were:
This isn't automatic. You have to initiate it — every single week or every two weeks, depending on how your account is set up. IDES processes certifications and then releases payments for approved weeks.
Illinois claimants can certify online through the IDES website, by phone, or through the ILogin portal system the state uses to authenticate claimants. The online system walks you through a series of questions about your previous week (or two weeks) of activity.
Typical questions during certification include:
You answer each question, and your responses determine whether you're approved for that week's payment.
Illinois requires claimants to actively search for work as a condition of receiving benefits. During most periods, this means:
Work search is not just checking job boards. Applying to positions, attending job fairs, contacting employers directly, and participating in reemployment services can all count. IDES may audit work search records, and claimants who can't document their activities risk having weeks denied or flagged for adjudication — a review process that can delay payments.
In Illinois, certification is generally done on a biweekly basis, meaning you certify for two weeks at a time. The IDES system assigns you a specific filing window. Certifying outside that window — or missing it — can result in late payments or a lapse in your claim.
If you miss a certification week, you may be able to file late in some circumstances, but late certifications are not always accepted, and gaps in claiming can affect your benefit year. The benefit year in Illinois runs for 52 weeks from your initial claim date, and unclaimed weeks within that year are generally forfeited.
Once you submit your certification, IDES processes the information and either:
If a week is flagged, it enters adjudication. This can take additional time, and you may be contacted for more information. Payments for flagged weeks are held until IDES makes a determination. ⏳
If you worked part-time or had any earnings during a claim week, you must report them. Illinois allows claimants to earn some income while collecting benefits, but earnings above a certain threshold reduce your weekly benefit amount on a sliding scale. Failing to report income — even accidentally — can result in an overpayment, which IDES will require you to repay, and in some cases may trigger fraud allegations.
| Mistake | Potential Consequence |
|---|---|
| Missing your certification window | Gap in benefits; possible claim lapse |
| Underreporting earnings | Overpayment; potential fraud flag |
| Failing to meet work search requirements | Week(s) denied; adjudication |
| Certifying "yes" to availability when traveling or ill | Possible denial of that week |
| Not keeping work search records | Inability to verify eligibility if audited |
How certification plays out in practice depends on a range of factors specific to your claim:
The certification process in Illinois is designed to confirm, week by week, that you continue to meet the same basic eligibility conditions that qualified you in the first place. Whether any given week is approved comes down to how your specific answers align with IDES's rules — and those rules can shift based on program updates, your individual claim history, and how your responses are interpreted during review.
