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 weekly certification — a regular check-in with the Illinois Department of Employment Security (IDES) that confirms you're still eligible for benefits during each claim week.
Here's what that process looks like, what it requires, and what factors shape how it works for different claimants.
Weekly certification (sometimes called "filing a weekly claim") is how Illinois verifies that you remain eligible for unemployment benefits on an ongoing basis. After your initial claim is approved and any waiting week has passed, you're required to certify — typically once a week — to confirm that you:
Until you certify, IDES does not release payment for that week. Missing a certification — or certifying late — can delay or forfeit benefits for that period. Illinois generally does not allow retroactive certification beyond a limited window, so timeliness matters.
Illinois claimants can complete weekly certifications through multiple channels:
Most claimants certify online. After logging in, you'll answer a series of questions covering the claim week — typically Sunday through Saturday. You can usually certify beginning the Sunday after a claim week ends, through the following Friday. The exact certification schedule is tied to your Social Security number in some cases, so IDES may assign you specific filing days.
During certification, IDES typically asks about the previous week. The questions generally cover:
| Topic | What IDES Wants to Know |
|---|---|
| Work search | Did you conduct the required number of job contacts? |
| Earnings | Did you work or earn any wages? |
| Availability | Were you physically able and available for full-time work? |
| Refusals | Did you refuse any job offer or referral? |
| School or training | Were you enrolled in any school or training program? |
Your answers to these questions directly affect whether IDES releases payment for that week. Inaccurate answers — even unintentional ones — can trigger an overpayment determination, which may require you to repay benefits and could carry additional penalties.
Illinois requires most claimants to conduct a minimum number of work search activities each week as a condition of receiving benefits. As of recent program rules, claimants are generally required to make at least three job contacts per week, though this requirement has shifted during various periods (including COVID-era waivers that have since ended).
Work search activities can include:
IDES may audit work search records at any point. Claimants are expected to keep written documentation of their job search activities — dates, employer names, contact methods, and outcomes — even if they don't submit that information every week. A failure to document or verify work search can result in disqualification for those weeks.
If you work part-time or pick up temporary hours, Illinois allows you to earn some wages without completely losing benefits for that week — but earnings must be reported during certification. The state applies a formula to reduce your weekly benefit amount (WBA) based on what you earned.
How much you can earn before benefits are entirely offset depends on your individual WBA and Illinois's partial benefit calculation rules. Those figures vary by claimant based on wage history and base period earnings.
Failing to report earnings is treated as fraud. Illinois takes overpayment recovery seriously, and penalties for misreporting can include repayment of all improperly received benefits plus additional fines.
Not every week certifies cleanly. Common issues that can pause or delay payment include:
No two claimants move through this process the same way. 📋 Your certification experience depends on:
Illinois's rules around certification, work search, partial wages, and benefit timing follow a specific framework — but how that framework applies depends entirely on the specifics of your claim, your work history, and what happened in any given week you're certifying for.
