If you're collecting unemployment in Illinois, filing your initial claim is only the first step. To keep receiving benefits, you must certify every week — confirming that you're still eligible and reporting any wages or work you had during that period. Missing a certification or reporting incorrectly can delay or stop your payments.
Here's how the Illinois weekly certification process works, what IDES asks, and what factors affect how it plays out for different claimants.
The Illinois Department of Employment Security (IDES) requires claimants to certify for each week they want to receive benefits. Certification is essentially a check-in: you're telling IDES that during the previous week, you were unemployed or underemployed, able to work, available for work, and actively looking for a job.
Illinois operates on a Sunday-through-Saturday benefit week. Certifications are typically submitted after the week has ended — usually between Sunday and Friday of the following week. If you miss that window, you may be able to certify late, but late certifications can trigger a review or delay payment.
Illinois offers three ways to complete your weekly certification:
📋 All three methods ask the same core questions. The format differs; the information you provide should be identical regardless of which you use.
Each week, you'll answer questions covering:
| Certification Question | What IDES Is Checking |
|---|---|
| Were you able and available to work? | Whether you met basic eligibility requirements that week |
| Did you look for work? | Whether you completed required job search activities |
| Did you work or earn any wages? | Whether you had partial earnings to report |
| Did you refuse any work? | Whether you turned down suitable employment |
| Did your situation change? | Whether new disqualifying circumstances arose |
Wages must be reported in the week they are earned, not when they're paid. This distinction matters — reporting wages in the wrong week is a common source of overpayment issues.
To remain eligible, Illinois claimants are generally required to make a minimum number of job contacts per week. The state has specific thresholds that can change, and not every job search activity counts the same way. Applying for a job, attending a job fair, or completing a skills assessment may each qualify differently depending on current IDES guidelines.
IDES can audit your work search records at any time. Claimants are expected to keep documentation of each contact — the employer name, date, method of contact, and position applied for. If you're asked to verify your search activities and can't, your benefits may be questioned.
Work search requirements are sometimes waived or modified in specific circumstances — for example, if you're part of an approved training program, on a temporary layoff with a definite recall date, or during periods when IDES issues special guidance (such as during widespread emergency conditions). Whether any waiver applies to your situation depends on the specific circumstances and current state policy.
Certifying while working part-time or picking up gig work is one of the more complicated parts of the process. Illinois uses a formula to calculate whether partial wages reduce your weekly benefit amount — and by how much. Generally, you can earn some wages without losing all your benefits, but there's a threshold beyond which benefits are reduced or eliminated for that week.
The key rules:
Failing to certify for a week doesn't necessarily cancel your claim entirely, but it does mean you won't receive benefits for that week in most cases. Some claimants assume that certifying for a following week automatically covers a missed one — it doesn't. Each week stands on its own.
If you missed a week and believe you were still eligible, IDES does have processes for addressing missed certifications, though outcomes depend on timing and circumstances.
Not every claimant's certification process looks the same. Several variables affect what you'll encounter:
Illinois's certification system is designed to verify ongoing eligibility — not just process payments automatically. Your responsibility as a claimant is to answer every question accurately, every week, for every week you want to be paid.
What your specific benefit amount looks like, how partial wages interact with it, and whether any holds or special circumstances apply to your claim depends on your work history, your separation, and where things stand with your individual claim at IDES.
