Illinois Department of Employment Security gives you 30 days from the date on your denial notice to file an appeal through IDES Online or by calling 800-244-5631. Illinois's 30-day window is relatively generous, but don't wait — appeals filed closer to the deadline leave less time to gather evidence. Continue certifying biweekly through IDES Online throughout the appeal. IDES pays retroactively for all weeks you have certified if the appeal succeeds.
- You have 30 calendar days from the mailing date on your IDES denial to file an appeal. File as soon as possible.
- Illinois Board of Review hearings are conducted by telephone. The referee is neutral; both you and your employer may present evidence.
- Continue certifying biweekly through IDES Online during the appeal — retroactive payment covers all certified weeks if you win.

Illinois's Appeals Process Structure
Illinois has a two-level appeal structure. The first level is a hearing before an IDES Referee — a telephone hearing where both you and your employer (if they participated) present your accounts under oath. The Referee reviews the evidence and issues a written decision. If the Referee's decision goes against you, you can escalate to the Illinois Board of Review, which reviews the hearing transcript without conducting a new hearing. Beyond that, circuit court review is the final avenue.
Filing the Appeal
File through IDES Online at ides.illinois.gov by selecting "Appeal a Decision." You can also mail a written appeal to the address on your denial notice, or call IDES at 800-244-5631 to request an appeal. In your appeal, include: the decision number from your denial notice, why you disagree with the determination, and what facts or evidence you have that supports your position. You do not need legal language — clear factual statements work best.
After filing, IDES schedules a telephone hearing and sends written notice of the hearing date to you and your employer. Hearings are typically scheduled within 4 to 8 weeks of the appeal filing. During this period, keep certifying biweekly through IDES Online.
Preparing for the Hearing
- Written documentation of your layoff: termination notice, WARN Act letter, HR email, or any written communication confirming job loss
- Emails, texts, or other records that support your account of events, especially if the denial was based on a disputed reason for separation
- Performance reviews or employment contracts, particularly if the denial alleged misconduct you believe didn't meet Illinois's legal standard
- Names of coworkers who witnessed the circumstances of your separation and who could testify by phone
Illinois's misconduct standard is specifically defined in the Illinois Unemployment Insurance Act. Deliberate violations of clear, known employer rules are misconduct. Negligence, poor judgment, and performance failures generally are not. If your denial was for misconduct, know specifically what the Illinois statute says — this argument is often what wins or loses these hearings.
Frequently Asked Questions
- How long do I have to appeal an Illinois unemployment denial?
- 30 calendar days from the mailing date on the Notice of Determination — not the date you received it. Illinois's 30-day window is the same as New York's, and longer than Texas (14 days) and Florida (20 days). Even with 30 days, file as soon as possible. Your strongest evidence is gathered while the events are fresh, and earlier filings get hearing dates sooner, reducing the period without payments. File within the first week after receiving the denial if possible. Late appeals are almost never accepted without extraordinary documented circumstances preventing a timely filing.
- Does Illinois pay me while my appeal is pending?
- Payments for the disputed period are held during the appeal. Continue certifying biweekly through IDES Online throughout the entire process. If the Referee's decision or the Board of Review's decision goes in your favor, IDES releases retroactive payment for all weeks you certified during the appeal. If you stop certifying during the appeal, those weeks become ineligible — IDES will not retroactively pay uncertified weeks even after a favorable decision. The appeal can take 4 to 12 weeks at the Referee level; certify every two weeks without exception throughout this period.
- My Illinois unemployment denial says I committed misconduct. What qualifies as misconduct under Illinois law?
- Illinois defines misconduct in the Unemployment Insurance Act as "the deliberate and willful violation of a reasonable rule or policy of the employer." The key word is "deliberate" — IDES and the Illinois courts have consistently held that negligence, incompetence, or performance failures without intentional disregard do not meet the definition. If you were fired for a mistake (not deliberately breaking a rule), for inability to perform (skill issue, not attitude), or for a first offense that was not reasonably foreseeable to result in termination, your conduct may not meet the misconduct standard. At your appeal hearing, ask the Referee specifically: "Was this conduct deliberate?" and focus your argument on the intentionality (or lack thereof) of the conduct at issue.
- I lost my Illinois UI appeal at the Referee level. What are my options?
- You can appeal to the Illinois Board of Review within 30 days of the Referee's written decision date. The Board reviews the transcript and record from the original hearing without conducting a new one. You may submit a written brief explaining why the Referee's legal conclusion was incorrect. The Board typically rules within 60 to 90 days of receiving the appeal. If the Board also denies your claim, the final avenue is circuit court review — a formal legal proceeding where the court reviews whether the Board's decision was supported by the evidence and correctly applied Illinois law. Legal representation is advisable at the circuit court level.
- My Illinois employer had a lawyer at the unemployment hearing. Should I have had one too?
- Lawyers are not required at Illinois IDES appeal hearings, and most claimants handle them without representation. However, if your employer was represented by an HR attorney or employment counsel, they likely had a prepared strategy, organized evidence, and knew which legal standards the Referee applies. Going forward into a Board of Review appeal or subsequent proceedings, having at least a consultation with an Illinois employment attorney is advisable. Many legal aid organizations in Illinois (Illinois Legal Aid Online at illinoislegalaid.org is a useful starting point) provide free assistance with unemployment appeals to eligible workers. For the hearing itself, thorough preparation of your facts and evidence often levels the playing field regardless of whether you have legal representation.
