Illinois unemployment insurance works like this: if you lose your job through no fault of your own and meet a recent-earnings test, the Illinois Department of Employment Security (IDES) pays you a portion of your lost wages for up to 26 weeks. Employers fund the program, not you. Your weekly check depends on what you earned during a defined base period and whether you have dependents, with a current individual maximum of $605 per week. To keep the money coming, you file an initial claim, then certify every two weeks that you are still unemployed, able to work, and looking for a job.
Who Qualifies
Two tests decide eligibility: why you left your last job, and how much you earned before you did.
On the first test, layoffs, reductions in force, and contract endings qualify. Quitting voluntarily without a good reason tied to your employer generally does not, and neither does being fired for misconduct. A disqualification lasts until you find new work and earn at least your weekly benefit amount in each of four separate calendar weeks. The voluntary-quit rule has narrow exceptions, including a documented medical condition, caring for a seriously ill family member, sexual harassment, and domestic violence.
On the earnings test, IDES looks at your base period: the first four of the last five completed calendar quarters before you filed. You need at least $1,600 in total wages during that window, and at least $440 of it must have been earned outside the quarter where you made the most money.1Illinois Department of Employment Security. Benefit Rights Information for Claimants and Employers If you fall short, IDES may try an alternative base period — the four most recently completed calendar quarters — to see whether you qualify that way.
You also have to be physically able to work and actually available to accept a suitable job if one comes up.2FindLaw. Illinois Statutes Chapter 820 Employment 405/500 – Eligibility for Benefits
How Much You’ll Get Each Week
IDES takes 47% of your average weekly wage during the two highest-earning quarters of your base period.3Illinois Department of Employment Security. Table 1 of Weekly Benefit Amounts State caps limit the result, and the ceiling is adjusted each year based on the statewide average weekly wage. For benefit years beginning on or after January 1, 2025:
- Individual with no dependents: up to $605 per week
- With a non-working spouse: up to $721 per week (adds a 9% spousal allowance)
- With one or more dependent children: up to $827 per week (adds a 17.2% child allowance)
Claiming a dependent raises the percentage of your average weekly wage used in the formula. A claimant with a dependent child can receive up to 64.2% of the statewide average weekly wage, compared with 47% for someone without dependents.3Illinois Department of Employment Security. Table 1 of Weekly Benefit Amounts Once set, your weekly amount holds for the rest of your benefit year unless your dependent status changes.
How Long Payments Last
Illinois pays up to 26 full weeks of benefits within a one-year benefit period.4Illinois Department of Employment Security. Unemployment Insurance Information The first eligible week is a waiting week, and nothing is paid for it, though you still have to file and certify.1Illinois Department of Employment Security. Benefit Rights Information for Claimants and Employers Actual payments begin with the second eligible week. Combined with processing time, your first deposit or check usually lands two to three weeks after you first file.
How to File Your Claim
Before you start, gather the information the application will ask for, so it doesn’t stall partway through:5Illinois Department of Employment Security. Information Needed to File Online
- Your Social Security number, with your name entered exactly as it appears on your Social Security card
- Alien registration information if you are not a U.S. citizen
- Your employment history for the last 18 months — for each employer, the name, mailing address, phone number, start and end dates, and reason you left
Be specific about the separation reason. “Layoff,” “position eliminated,” or “contract ended” tells IDES far more than “no longer employed.” If your former employer disputes what you report, IDES investigates before issuing a determination.
You can file one of three ways: online through the IDES website on business days, by phone on the Tele-Serve system at (312) 338-4337 Monday through Friday between 3:00 a.m. and 7:30 p.m., or by mailing a paper application to your local IDES office.
After the claim is processed, IDES mails a UI Finding letter. It confirms your claim was received, shows your weekly benefit amount, and assigns the specific day every two weeks when you must certify.6Illinois Department of Employment Security. Teleserve If that letter doesn’t arrive within two weeks, contact IDES Claimant Services.
You also choose how to be paid: direct deposit to a bank account, or a paper check by USPS.7Illinois Department of Employment Security. Payment Methods If you pick nothing, IDES defaults to a paper check. Direct deposit is faster — benefits typically land two to three business days after certification, versus roughly eight days for a check in the mail. You can change the method later through your online account.
Certifying Every Two Weeks
Filing the initial claim is just the start. Every two weeks, you certify that you are still unemployed, able to work, available for work, and actively looking for a job, and you report any income earned during the period. You can certify online or through Tele-Serve.8Illinois Department of Employment Security. FAQs for Claimants – Section: Certification and Receiving Benefits Do it on your assigned day between 3:00 a.m. and 7:30 p.m.; missing that window can delay or suspend payment.
You must also register at IllinoisJobLink.com and upload a resume. This is the state’s official job-matching system, and registration is required for eligibility unless IDES tells you a narrow exception applies.8Illinois Department of Employment Security. FAQs for Claimants – Section: Certification and Receiving Benefits Keep your own record of job search activities (employer names, dates of contact, how you applied), because IDES can request your work search history at any time. Your IllinoisJobLink.com activity log works as proof if you’re audited.
Working Part-Time While You Collect
Picking up part-time work doesn’t automatically end your claim. How earnings interact with your weekly benefit amount decides what you receive:9Illinois Department of Employment Security. Partial Benefits (Working Part Time)
- Earn 50% or less of your weekly benefit amount, and you get the full benefit for that week.
- Earn more than 50%, and only the portion above the 50% threshold is deducted from your benefit.
- Earn as much as or more than your weekly benefit amount, and nothing is paid for that week.
Say your weekly benefit amount is $400 and you earn $250 in a week. The 50% threshold is $200, so $50 is deducted, and you receive $350. Report gross wages when you certify, even if you haven’t been paid yet; IDES counts the week you earned the money, not the week the paycheck arrived.
Taxes on Your Benefits
Unemployment benefits are taxable income on your federal return.10Internal Revenue Service. Topic No. 418, Unemployment Compensation You can have taxes withheld automatically from each payment: 10% for federal income tax and 4.95% for Illinois state income tax. Elect withholding by completing the IDES Income Tax Withholding Election form when you file, or by sending a TAX-2 form to IDES later by fax or mail.
Skip withholding and you may need to make quarterly estimated payments to avoid an underpayment penalty. Early in the following year, IDES sends a Form 1099-G showing total benefits paid and any taxes withheld.11Internal Revenue Service. Instructions for Form 1099-G That’s the form you use to report the income at tax time.
If Your Claim Is Denied
You have 30 calendar days from the mailing date on the determination letter to appeal.12Illinois Department of Employment Security. Appeals The first step is a Request for Reconsideration explaining why you disagree. If that doesn’t resolve it, the case moves to the IDES Appeals Division for a hearing before an administrative law judge called a Referee. Both you and your former employer can present evidence and testimony.
If you disagree with the Referee’s decision, you have another 30 days to appeal to the Board of Review. Miss the 30-day deadline at any stage and the prior decision generally becomes final. You don’t need an attorney, but one can help if the facts of your separation are disputed.
Overpayments and Fraud
If IDES pays you more than you were entitled to, it will seek repayment. For honest mistakes, such as miscalculating hours, IDES can recover the amount from future benefit payments, with no single deduction exceeding 25% of your weekly benefit amount.
Intentional fraud is treated far more harshly. Knowingly providing false information to collect benefits means repaying the full overpayment and losing eligibility for six additional weeks on a first offense, with two more weeks added for each later offense.13U.S. Department of Labor. Report Unemployment Insurance Fraud Federal law also requires states to add a penalty of at least 15% on top of the fraudulent amount. Federal prosecutors can pursue serious cases under mail and wire fraud statutes, which carry potential prison time, and fraudulent overpayments can be recovered by intercepting future income tax refunds.
