If you're collecting unemployment in Illinois, filing your initial claim is only the first step. To actually receive benefit payments, you must certify regularly — confirming that you remain eligible week by week. This process is called weekly certification, and missing it or answering questions incorrectly can delay or interrupt your payments.
Here's how it works in Illinois and what you need to know to stay on track.
Certification is the process of reporting to the Illinois Department of Employment Security (IDES) each week to confirm you're still eligible for benefits. Think of it as checking in — Illinois needs to verify that during the past week you were:
Until you certify, IDES has no basis to release a payment for that week. The state doesn't pay automatically — the certification triggers each payment.
Illinois claimants can certify in two main ways:
Online through the IDES website — This is the most common method. You log into your account on the IDES portal and answer a series of questions covering the certification period.
By phone through Tele-Serve — Illinois maintains a phone certification system for claimants who prefer or need a non-online option. The system walks you through the same questions interactively.
Both methods are available during specific hours, and Illinois typically requires certification for each week you're claiming benefits — you generally cannot skip weeks and catch up later without a specific reason.
The questions you answer during certification are consistent week to week. They generally cover:
| Topic | What IDES Is Asking |
|---|---|
| Work and availability | Were you able and available to work each day? |
| Earnings | Did you work or earn any wages during this week? |
| Job search | Did you make the required number of job contacts? |
| Refusal of work | Did you refuse any suitable work offer? |
| School or training | Were you attending school or a training program? |
| Illness or injury | Were anything that prevented you from working? |
Illinois requires claimants to answer honestly. Providing false information — even accidentally misremembering — can result in an overpayment determination, which means you'd have to repay benefits and could face additional penalties.
Illinois requires most claimants to conduct a minimum number of job search activities each week to remain eligible. As of recent program rules, that threshold has been set at three job search activities per week, though this requirement can be modified during periods of high unemployment or under specific program waivers.
Qualifying activities typically include:
You're required to keep records of your job search contacts — employer names, contact information, dates, and the type of activity. IDES can request these records, and not having them can jeopardize your eligibility for the weeks in question.
Illinois generally requires claimants to serve a waiting week — the first eligible week of a new benefit year for which no payment is issued. You still must certify for this week; you just won't receive a payment for it. The waiting week establishes the start of your benefit year.
If you worked part-time during a certification week, you don't necessarily lose benefits entirely. Illinois uses an earnings disregard formula — a portion of your wages is disregarded before your weekly benefit amount is reduced dollar for dollar.
The specifics of that formula depend on your weekly benefit amount (WBA), which is calculated based on your wages during the base period (the roughly 12–18 month window before you filed). Your WBA is fixed when your claim is established; it doesn't change week to week.
What does change is how much you earned in a given week — and that directly affects whether you receive a full payment, a partial payment, or no payment for that week.
Missing a certification deadline in Illinois can result in a gap in your payments. In some cases, IDES allows backdating for missed weeks, but that typically requires a documented reason and is not guaranteed. The further you fall behind, the harder it becomes to recover those weeks.
If you had a legitimate reason for missing a certification — illness, a system outage, a family emergency — IDES has processes for addressing gaps, but they involve additional review.
Occasionally a certification will trigger a review — called adjudication — if something in your answers raises a question about eligibility. This might happen if you reported earnings, indicated you refused work, or if your employer filed a protest on your claim.
During adjudication, IDES may pause your payments while they investigate. You may be asked to provide additional information or documentation. This does not automatically mean your claim is denied, but it does mean a decision is pending.
How straightforward your weekly certification is depends on several factors that vary by claimant:
Illinois administers its unemployment program under state law within the federal framework — meaning the rules above reflect how Illinois generally operates, but your specific claim history, earnings record, and separation circumstances determine what actually applies to your situation.
