If you're collecting unemployment benefits in Illinois, filing your initial claim is only the first step. To keep receiving payments, you must complete a process called certification — a regular check-in that confirms you're still eligible for benefits each week. Missing a certification, or answering questions incorrectly, can delay or stop your payments.
Here's how the Illinois certification process generally works.
Certification is how Illinois confirms that you remain eligible for benefits during a given week. Each time you certify, you're essentially telling the Illinois Department of Employment Security (IDES) that during that week you were:
Illinois uses a biweekly certification schedule — meaning you certify for two weeks at a time, not one. This is different from some other states, where claimants certify weekly. Missing your certification window can result in delayed payments or forfeited weeks.
Illinois claimants can certify in two primary ways:
Online: Through the IDES online portal (ILogin), available 24/7. This is the fastest and most commonly used method.
By phone: Using the Tele-Serve system, available during designated hours. Callers respond to an automated set of questions.
During certification, you'll typically be asked about:
Accuracy matters here. Illinois cross-references reported wages with employer records. Underreporting earnings — even unintentionally — can result in an overpayment, which IDES will require you to repay, sometimes with penalties.
Illinois requires a waiting week — the first eligible week of your claim during which you certify but do not receive payment. This is standard in many states and is built into the benefit year. You still need to certify for this week; you simply won't be paid for it.
Certifying isn't just a formality — it's tied directly to Illinois's work search requirements. To remain eligible, claimants are generally required to make a minimum number of job search contacts each week. As of recent program rules, Illinois typically requires three job search activities per week, though this can change based on program updates or labor market conditions.
Acceptable activities can include:
You must keep records of your job search activities, including employer names, contact information, position applied for, and the date. IDES can audit these records at any time. If you can't document your search, your benefits could be affected.
Working part-time while collecting benefits doesn't automatically disqualify you — but it does affect your payment. Illinois uses an earnings disregard formula: a portion of any wages you earn in a given week may be disregarded before reducing your benefit payment.
| Scenario | Effect on Benefits |
|---|---|
| No wages earned | Full weekly benefit amount (if otherwise eligible) |
| Part-time wages below threshold | Partial benefit paid after earnings disregard |
| Wages at or above weekly benefit amount | No benefit paid for that week |
| Wages not reported | Potential overpayment and penalties |
The specific disregard amount and calculation formula are set by IDES and can change. Your actual payment will depend on your weekly benefit amount and what you earned.
If you miss your biweekly certification window, Illinois may allow you to certify late — but late certifications aren't always accepted, and missed weeks may not be recoverable. IDES does offer a process to request payment for missed weeks in some circumstances, but approval isn't guaranteed and depends on the reason for missing the deadline.
Recurring missed certifications can trigger a review of your claim or result in benefits being suspended until you re-engage with the process.
How certification plays out in practice depends on several factors that vary from one claimant to the next:
Illinois's certification rules, work search minimums, and disregard formulas reflect state-level policy decisions that can be updated. What applies to one claimant's benefit year may differ slightly from another's — and your own work history, wages, and separation circumstances are what ultimately determine how much you receive and for how long.
