How to Appeal an Unemployment Denial in Illinois
Reviewed by DocDraft Legal Team · Illinois · Last updated 2026-09-06
An unemployment appeal is the formal request you file to challenge a decision that denied, reduced, or ended your unemployment benefits, asking a neutral judge to review the agency's ruling. In Illinois, the Department of Employment Security (IDES) issues that decision as a claims adjudicator's Finding or Determination. You appeal in writing within 30 days of the mailing date on the notice, and an IDES administrative law judge called a Referee hears the case (820 ILCS 405/800). If the Referee rules against you, you can appeal again to the Board of Review (820 ILCS 405/801). If the filing deadline falls on a weekend or holiday it rolls to the next open day, and you should keep certifying every two weeks while the appeal is pending.

How do I appeal an unemployment denial in Illinois?
Submit a written appeal within 30 days of the mailing date on your IDES claims adjudicator's Finding or Determination. You can complete the Request for Reconsideration of Claims Adjudicator's Determination form or write a signed letter, then mail, fax, or deliver it to your local IDES office (820 ILCS 405/800).
How long do I have to appeal an unemployment decision in Illinois?
You have 30 calendar days from the mailing date printed on your IDES claims adjudicator's Finding or Determination. Missing the deadline can make the determination final and end your appeal rights, though if the last day falls on a weekend or holiday you may file on the next business day.
What is the IDES appeal form in Illinois?
Illinois uses the Request for Reconsideration of Claims Adjudicator's Determination form, but IDES also accepts a plain signed letter instead. Either way, identify the decision you are appealing and explain why you disagree. Mail, fax, or deliver it to the local IDES office listed on your Finding or Determination.
Can I keep receiving benefits while my Illinois appeal is pending?
Keep certifying for benefits every two weeks while your appeal is pending, as long as you remain unemployed. IDES can only pay you for weeks you certified and were otherwise eligible, so stopping certification can cost you back payments even if you win your appeal before the Referee.
Illinois unemployment appeal law at a glance
In Illinois, the Department of Employment Security (IDES) decides unemployment eligibility and issues a claims adjudicator's Finding or Determination. A claimant who disagrees appeals in writing within 30 days of the mailing date on that notice (820 ILCS 405/800). The first-level appeal goes to an IDES administrative law judge called a Referee, an attorney who holds a hearing and decides whether benefits are payable. If the Referee rules against you, a second-level appeal goes to the Board of Review, an independent five-person body appointed by the governor, within 30 days of the mailing of the Referee's decision (820 ILCS 405/801). If the filing deadline falls on a weekend or a day IDES offices are closed, the appeal may be filed on the next open day. IDES advises claimants to keep certifying every two weeks while the appeal is pending, as long as they remain unemployed.
Appealing an Illinois unemployment denial after a quit-versus-fired dispute
Suppose IDES mails you a claims adjudicator's Finding or Determination denying benefits because it treated your job separation as a voluntary quit. You disagree, believing you were let go. Because the notice controls the timeline, you note the mailing date and file your appeal within 30 days, using the Request for Reconsideration form and explaining that your separation was an involuntary layoff, with your final paycheck stub and a supervisor email attached. You keep certifying every two weeks while you wait. At the hearing, a Referee reviews the evidence and questions both sides. If the Referee still rules against you, you file a second-level appeal to the Board of Review within 30 days. Attorney review of your appeal statement is available through DocDraft.

Suggested Compliance Checklist
Find the mailing date on your IDES notice
The day you receive the Finding or Determination days after startingLocate the mailing date printed on your IDES claims adjudicator's Finding or Determination. That date starts the 30-day appeal window under 820 ILCS 405/800, so calendar it immediately and work backward from it.
Read the reason IDES gave for the decision
As soon as you receive the notice days after startingIdentify the exact eligibility issue IDES relied on, such as a quit-versus-fired dispute, availability, or an overpayment. Your appeal is stronger when it responds directly to that finding rather than restating your situation generally.
Write your appeal on the reconsideration form or in a letter
Within 30 days of the notice mailing date days after startingComplete the Request for Reconsideration of Claims Adjudicator's Determination form or a signed letter identifying the decision appealed and why it is wrong.

Keep a dated copy and proof of sending. If the last day falls on a weekend or closed day, file on the next open day.
Keep certifying for benefits
Every two weeks while the appeal is pending days after startingContinue certifying for benefits during the appeal, as long as you remain unemployed. IDES can only pay weeks you certified and were otherwise eligible, so unbroken certification protects back payments if the Referee rules in your favor.
Prepare for the Referee hearing
Before the hearing date on your notice days after startingGather documents and witnesses, review the IDES file, and organize the facts that support your position. IDES mails a hearing notice with the date and format. Attending is critical; if you miss it, you must request to reopen within 10 days.

Frequently Asked Questions
An unemployment appeal is your formal, written request asking a neutral Referee, an IDES administrative law judge, to review a decision that denied, reduced, or ended your benefits. In Illinois it is filed against a claims adjudicator's Finding or Determination, and it triggers a hearing before the Referee to decide whether benefits are payable.
The IDES determination is the agency's initial decision on your eligibility, sent as a claims adjudicator's Finding or Determination. An appeal is the separate step where you challenge that decision before a Referee who is independent of the adjudicator. The determination comes first; the appeal is how you contest it within 30 days.
You have 30 calendar days from the mailing date on your IDES claims adjudicator's Finding or Determination to file a written appeal (820 ILCS 405/800). The clock runs from the notice mailing date, not the day you happened to open the envelope, so calendar it immediately.
If you do not appeal within 30 days, the determination becomes final under 820 ILCS 405/800. If the last day fell on a weekend or a day IDES offices were closed, you may file on the next open day. If you missed a hearing, you can request to reopen it within 10 days.
A Referee, an IDES administrative law judge who is an attorney, decides the first-level appeal independent of the claims adjudicator. The Referee holds a hearing, reviews the IDES file and your evidence, questions both sides, and then issues a written decision on whether unemployment insurance benefits are payable.
IDES mails a hearing notice, and the hearing before the Referee is often held by phone. The Referee takes testimony from you and your former employer, reviews documents, and lets each side ask questions. A written decision follows, explaining the result and your right to appeal to the Board of Review.
Yes. If the Referee rules against you, you can file a second-level appeal to the Board of Review within 30 days of the mailing of that decision (820 ILCS 405/801). The Board, a five-person body appointed by the governor, reviews the hearing record rather than holding a new hearing.
Yes. IDES instructs claimants to keep certifying every two weeks while an appeal is pending, as long as you remain unemployed, because you can only be paid for weeks you certified and otherwise met eligibility rules. Skipping it can forfeit weeks the Referee might later approve in your favor.
