How to Appeal an Unemployment Denial in Arizona
Reviewed by DocDraft Legal Team · Arizona · 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 Arizona, the Department of Economic Security (DES) issues that decision as a Determination of Eligibility or a Determination of Overpayment. You appeal in writing within 15 days of the date on that determination, and an administrative law judge in the DES Office of Appeals hears the case (A.R.S. section 23-773). If the judge rules against you, you can file a further appeal to the DES Appeals Board within 30 days (A.R.S. section 23-671). A late appeal may still be allowed for good cause, and you should keep filing your weekly claims while the appeal is pending.

How do I appeal an unemployment denial in Arizona?
File a written appeal within 15 days of the date on your DES Determination of Eligibility or Determination of Overpayment. You can use the Request for Reconsideration/Appeal form (UIB-0126A) or a signed letter, and file it by mail, fax, phone, in person, or through the CACTUS portal (A.R.S. section 23-773).
How long do I have to appeal an unemployment decision in Arizona?
You have 15 calendar days from the date printed on your DES Determination of Eligibility or Determination of Overpayment. Missing the deadline can end your appeal rights, though DES may allow a late appeal only for narrow good cause, such as departmental error or the post office failing to deliver your determination.
What is the DES appeal form in Arizona?
Arizona uses the Request for Reconsideration/Appeal form, UIB-0126A, available in English and Spanish, but DES also accepts a written appeal. Either way, identify the determination you are appealing and explain why you disagree. File it by mail, fax, phone, in person, or online through the CACTUS portal.
Can I keep receiving benefits while my appeal is pending in Arizona?
Keep filing your weekly claims for benefits while your appeal is pending. DES can only pay you for weeks you made a timely claim and met eligibility rules, so stopping can cost you back payments even if you win. Filing weekly does not guarantee payment, but it preserves weeks the judge may later approve.
Arizona unemployment appeal law at a glance
In Arizona, the Department of Economic Security (DES) decides unemployment eligibility and issues a Determination of Eligibility or a Determination of Overpayment. A claimant who disagrees appeals in writing within 15 days of the date on that determination (A.R.S. section 23-773). The first-level appeal goes to an impartial administrative law judge in the DES Office of Appeals, who holds a hearing on the Unemployment Insurance issues. If the judge rules against you, a further appeal goes to the DES Appeals Board within 30 days under A.R.S. section 23-671. A late appeal is allowed only for narrow good cause, such as departmental error, misinformation, or the post office failing to deliver the determination. DES advises claimants to keep filing weekly claims for benefits while the appeal is pending.
Appealing an Arizona unemployment denial after a quit-versus-fired dispute
Suppose DES mails you a Determination of Eligibility denying benefits because it treated your job separation as a voluntary quit. You disagree, believing you were let go. Because the determination date controls the timeline, you note that date and file your appeal within 15 days, using the UIB-0126A form and explaining that your separation was an involuntary layoff, with your final paycheck stub and a supervisor email attached. You keep filing your weekly claims while you wait. At the hearing, an administrative law judge in the Office of Appeals reviews the evidence and questions both sides. If the judge still rules against you, you file a petition for review with the DES Appeals Board within 30 days. Attorney review of your appeal statement is available through DocDraft.

Appeal deadline
15 calendar days from the date on the DES Determination of Eligibility or Determination of Overpayment, under A.R.S. section 23-773. The clock runs from the determination date, and in-person delivery of notification shortens the window to 7 calendar days.
How to file
In writing using the Request for Reconsideration/Appeal form (UIB-0126A) or a signed appeal, by mail, fax, phone, in person at an Employment Service Office, or through the CACTUS portal. The appeal must identify the determination and explain why you disagree.
Who hears it
An impartial administrative law judge in the DES Office of Appeals holds the first-level hearing. A second-level petition for review goes to the DES Appeals Board within 30 days under A.R.S. section 23-671.
Late appeals
Allowed only for narrow good cause. DES generally accepts a late appeal only for departmental error or misinformation, or the post office failing to properly deliver the determination.
Benefits during appeal
DES advises claimants to keep filing weekly claims while the appeal is pending, because payment is only possible for weeks a timely claim was made and eligibility requirements were met.
Suggested Compliance Checklist
Find the determination date on your DES notice
The day you receive the Determination of Eligibility days after startingLocate the date printed on your DES Determination of Eligibility or Determination of Overpayment. That date starts the 15-day appeal window under A.R.S. section 23-773, so calendar it immediately and work backward from it.
Read the reason DES gave for the decision
As soon as you receive the notice days after startingIdentify the exact eligibility issue DES 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 UIB-0126A or in a letter
Within 15 days of the determination date days after startingComplete the Request for Reconsideration/Appeal form (UIB-0126A) or a signed appeal identifying the determination, why it is wrong, and your contact details. Attach supporting pay records or statements. Attorney review of your appeal statement is available through DocDraft.
File the appeal within 15 days
By the 15th day after the determination date days after startingSubmit the appeal by mail or fax to the address on your determination, by phone, in person, or through the CACTUS portal before the 15-day deadline. Keep a dated copy and proof of sending. If you are already late, file immediately and explain the good-cause reason.
Keep filing your weekly claims
Every week while the appeal is pending days after startingContinue filing your weekly claims during the appeal. DES can only pay weeks you made a timely claim and were otherwise eligible, so unbroken weekly filing protects back payments if the administrative law judge rules in your favor.
Prepare for the administrative law judge hearing
Before the hearing date on your notice days after startingGather documents and witnesses, review the DES file, and organize the facts that support your position. The Office of Appeals mails a hearing notice with the date and format. Attending is critical, because missing it can lead to a decision against you.
Note your Appeals Board rights
Within 30 days of the ALJ decision days after startingIf the administrative law judge denies your appeal, you can petition the DES Appeals Board within 30 days under A.R.S. section 23-671. The Board reviews the hearing record, so make sure every argument and exhibit is presented at the ALJ hearing.

Frequently Asked Questions
An unemployment appeal is your formal, written request asking a neutral administrative law judge to review a DES decision that denied, reduced, or ended your benefits. In Arizona it is filed against a Determination of Eligibility or a Determination of Overpayment, and it triggers a hearing in the DES Office of Appeals.
The DES determination is the agency's initial decision on your eligibility, sent as a Determination of Eligibility or Determination of Overpayment. An appeal is the separate step where you challenge that decision before an administrative law judge who is independent of the deputy who decided it. The determination comes first; the appeal contests it within 15 days.
You have 15 calendar days from the date on your DES Determination of Eligibility or Determination of Overpayment to file an appeal (A.R.S. section 23-773). The clock runs from the determination date, not the day you happened to open the envelope, so calendar it as soon as the notice arrives.
A late appeal is allowed only for narrow good cause. DES says late appeals are generally accepted only for departmental error or misinformation, or the post office failing to properly deliver the determination. File as soon as possible and explain the specific reason you missed the 15-day deadline.
An impartial administrative law judge in the DES Office of Appeals decides the first-level appeal, independent of the deputy who issued the determination. The judge holds a hearing on the Unemployment Insurance issues, reviews the DES file and your evidence, questions both sides, and then issues a written decision.
The Office of Appeals mails a hearing notice, and the hearing is usually held by phone. The administrative law judge takes testimony under oath from you and DES or your former employer, reviews documents, and lets each side ask questions. A written decision follows, explaining the result and further appeal rights.
Yes. If the administrative law judge rules against you, you can file a written petition for review with the DES Appeals Board within 30 days of the decision (A.R.S. section 23-671). The Board reviews the hearing record rather than holding a new hearing, so present all your evidence at the ALJ stage.
Yes. DES instructs claimants to keep filing weekly claims for benefits while an appeal is pending, because you can only be paid for weeks you made a timely claim and met eligibility rules. Filing does not guarantee payment, but skipping it can permanently forfeit weeks the judge might later approve.
