If you're collecting unemployment benefits in Illinois, filing your initial claim is only the first step. To keep receiving payments, you must regularly certify with the Illinois Department of Employment Security (IDES). This process — often called "IDES certify" or weekly certification — is how the state confirms you're still eligible for benefits each week.
Here's how it works, what it involves, and what factors can affect your certification and payments.
Certification is the process of reporting your status to IDES on a regular basis after your claim is approved. It serves as your confirmation that:
Without completing certification, IDES will not release benefit payments — even if your claim is already approved and active.
Illinois uses a bi-weekly certification schedule, meaning you certify every two weeks rather than every single week. During each certification, you're reporting on the two-week period that just passed — answering questions about your work status, any earnings, and your job search activity for both weeks combined.
IDES assigns claimants specific certification windows. Missing your window can delay or interrupt your payments, so it's important to know when your certification period opens and closes.
IDES offers multiple ways to complete your certification:
The online portal and TeleServe system walk you through a series of questions. You'll typically be asked whether you worked during the certification period, how much you earned if you did, whether you were able and available for work, and whether you refused any work offers.
Answering these questions accurately matters. Providing false information during certification is considered fraud and can result in disqualification, repayment demands, and additional penalties.
The questions you'll answer are designed to verify ongoing eligibility. Common certification questions include:
| Question Topic | Why It's Asked |
|---|---|
| Did you work during this period? | Earnings can reduce or eliminate benefits |
| How much did you earn (gross)? | IDES calculates a partial benefit if applicable |
| Were you able and available to work? | Confirms continued eligibility |
| Did you refuse any work? | Refusing suitable work can disqualify you |
| Did you look for work? | Illinois requires active job search |
| Did you receive any other income? | Pension, severance, or other income may affect benefits |
Illinois requires most claimants to conduct a job search as a condition of receiving benefits. During certification, you'll be asked to confirm that you looked for work during the period you're claiming.
IDES may require you to keep a work search record documenting your job search activities — employer names, contact information, dates, and the type of contact made. You generally don't submit this log with every certification, but you should maintain it because IDES can audit your work search compliance and request records at any time.
Certain claimants may be exempt from the job search requirement — for example, those who are temporarily laid off with a definite return-to-work date, or union members seeking work through a union hiring hall. Whether an exemption applies depends on the specific facts of your situation.
If you work part-time or pick up temporary work while collecting benefits, you're still required to report those earnings during certification. Illinois uses a formula to determine whether and how much your benefit payment is reduced based on what you earned.
Generally, earning some wages doesn't automatically eliminate your payment — but it does reduce it. The specific formula, income thresholds, and how Illinois handles partial benefits are set by state law and can change. Your actual payment for any given week will reflect the earnings you report.
Failing to report earnings is one of the most common causes of overpayments — situations where IDES determines you were paid more than you were entitled to and requires repayment, sometimes with penalties.
Missing your certification window doesn't automatically end your claim, but it does interrupt your payments. In some cases, IDES may allow you to certify late, but there's no guarantee that missed certification periods will be paid retroactively.
If you miss a certification and your claim lapses, you may need to reopen your claim before payments can resume — which can involve additional processing time.
Sometimes a certification period is flagged for adjudication — a review process where IDES examines your responses before releasing payment. This can happen if you reported earnings, indicated you refused work, or if there's a question about your continued eligibility.
During adjudication, payment for that period is held while IDES investigates. You may be asked to provide additional information. How long adjudication takes, and what it means for your payments, varies depending on the issue involved.
No two claimants have identical certification experiences. What you report, how IDES processes it, and what your payments look like depend on:
Illinois administers its unemployment program under both state law and a federal framework — but the day-to-day rules, the specific questions on certification, the earnings formulas, and how adjudication is handled are all governed by Illinois-specific rules and procedures. How your certifications affect your payments comes down to your own wage history, what you report, and what's happening with your specific claim.
