You have 30 calendar days from the date the determination was mailed to file an Illinois unemployment appeal — the clock runs from the date on the letter, not the day you read it. Many first denials are overturned at the hearing, usually on the separation question (misconduct or quit), and the hearing is the one place both sides are under oath.
This guide gives the deadline, how to file, what the hearing is like, what evidence wins, and what happens to your benefits while you wait. Figures are from the United States Department of Labor’s state-law tables effective January 1, 2026, read October 2026; confirm the current amount with Illinois Department of Employment Security (IDES) before you rely on it.

How to File an Illinois Unemployment Appeal
A first-level appeal starts as a Request for Reconsideration of the Claims Adjudicator’s Determination. You can send a letter or use the IDES form, and mail it, fax it or hand it in at your local IDES office. The address and fax number are printed on your determination. The appeal must include your name, address, claimant ID or SSN, and why you disagree.
If reconsideration is denied, IDES sends the appeal to the Appeals Division automatically. The appeals page is https://ides.illinois.gov/unemployment.html.
What an Illinois Unemployment Appeal Hearing Is Like
The state generally holds hearings by telephone. An in-person hearing is granted only for good cause under 56 Ill. Adm. Code 2720. Hearings are scheduled in 30-minute slots. Stay available to take the Referee’s call for at least 1 hour from the scheduled time, or the appeal may be dismissed. It is run by Referee.
IDES also calls this role Administrative Law Judge in its hearing guidance.; you and the employer each testify, answer the officer’s questions and can question each other’s witnesses. Give the Referee your witnesses’ names and phone numbers before the hearing day. Each side brings its own witnesses, and testimony is taken under oath. If a witness or document won’t be provided willingly, ask the Referee right away for a subpoena.
The request must say what each witness or document will prove (56 Ill. Adm. Code 2720.225).
Evidence That Wins an Illinois Unemployment Appeal
- Send written evidence to the Referee and every other party at least 24 hours before the hearing, because exhibits the other side never received may not be considered
- Your determination letter and the docket number
- A written timeline of the separation, with dates
- Emails, texts, write-ups or schedules that show why you left or were let go
- Work search records, kept until the appeal is resolved
Send every document to the hearing office and the employer before the hearing by the method the notice specifies; the officer can only consider what is in the record.
Your Benefits While the Illinois unemployment appeal Is Pending
Benefits are generally not paid while the claimant’s appeal is pending. You must keep certifying every two weeks for as long as you remain unemployed. If you win, you can be paid only for the weeks you certified and met all eligibility rules for, so skipping certifications can cost you those weeks. The Referee’s written decision is customarily mailed within 45 days of the appeal filing date (56 Ill. Adm.
Code 2720). This is a usual target, not a guarantee. IDES says only that it mails the decision “as soon as possible” after the hearing.
Illinois Unemployment Appeal: The Second Level and the Courts
The Board of Review, an independent 5-member body appointed by the governor, reviews the Referee’s decision and hearing record (820 ILCS 405/803). New evidence is allowed only if you explain why, for reasons beyond your control, you couldn’t present it at the hearing (Rule 2720.315(b)). The Board generally decides within 120 days, and a party can ask in writing for up to a 30-day extension.

The final appeal is an administrative review action in the circuit court of the county where you live, or Cook County if you live out of state (820 ILCS 405/1100). Under the Administrative Review Law, it must be filed within 35 days of service of the Board of Review decision (735 ILCS 5/3-103).
Missing the Illinois Unemployment Appeal Deadline, and Employer Appeals
If an appeal looks late and the appeal letter doesn’t address timeliness, the Referee dismisses it without a hearing (56 Ill. Adm. Code 2720.207). Explain the delay in the letter itself and include proof, such as postmarks or the date you received the notice. A mailed appeal counts as filed by its postmark date.
If the deadline falls on a day IDES is closed, the appeal can be filed the next business day. If the employer appeals a decision that awarded you benefits, IDES generally keeps paying on that award while the appeal is pending. Keep certifying and take part in the hearing. If the employer loses, the benefits may be charged to its account.

Illinois — the bottom line
