The Illinois Department of Employment Security handles all unemployment claims

To file for unemployment in Illinois, you work with the Illinois Department of Employment Security (IDES), which is the state agency that processes claims, determines your may be able to access, and pays benefits. You cannot file through a local office or by mail—all claims go through IDES's online portal or by phone. The process takes about two weeks from the time you file until you receive your first payment, though that timeline can stretch if IDES needs to verify information with your employer.

Illinois uses a shared-work program and regular unemployment insurance, so the path you take depends on whether your employer has enrolled in shared work (a program that lets companies reduce hours instead of laying off workers) or whether you were laid off or had hours cut. Most people file for regular unemployment insurance, which is what this guide covers.

Key Takeaways

  • File online through IDES.Illinois.gov or by phone at 1-800-244-5631 within two weeks of your job loss or hour reduction to protect your benefit start date.
  • You will need your Social Security number, driver's license or state ID number, and your most recent employer's name, address, and phone number.
  • IDES will contact your employer to verify the reason you left work; if your employer disputes the claim, you may be asked to participate in a phone hearing.
  • Weekly benefit amounts in Illinois range based on your prior earnings, and you must report your work search activities each week to keep receiving payments.
  • If IDES denies your claim, you have 30 days to file an appeal with the Illinois Department of Labor.

File online or by phone within two weeks of job loss

The fastest way to file is through the IDES website at IDES.Illinois.gov. You create an account, answer questions about your employment history and the reason you left work, and submit your claim. The online system is available 24 hours a day. If you prefer to file by phone, call 1-800-244-5631 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Both methods take about 20 to 30 minutes.

The two-week window matters because your benefit start date is typically the Sunday of the week you file. If you wait four weeks to file, you lose two weeks of potential payments. Illinois does not backdate claims, so filing early protects your benefit amount.

Have these documents ready before you start: your Social Security number, your driver's license or Illinois state ID number, your most recent employer's name and address, your employer's phone number, and the date you last worked. If you were laid off, know the reason (for example, "lack of work" or "business closure"). If you quit, be ready to explain why—IDES will ask whether you had good cause related to work.

IDES verifies your claim with your employer

After you file, IDES sends a form to your employer asking them to confirm the reason you left work and whether you are may be able to access for benefits. Your employer has about 10 days to respond. If your employer says you were fired for misconduct, or if there is a disagreement about whether you quit or were laid off, IDES will contact you to gather more information.

In some cases, IDES schedules a phone hearing where you and your employer both explain your side. You do not need a lawyer, but you can bring one if you want. The hearing officer listens to both accounts and makes a decision. This process usually takes two to four weeks after your initial claim.

Common reasons IDES approves claims: lack of work, business closure, reduction in hours, and quitting for good cause (such as unsafe working conditions or a substantial cut in pay). Common reasons for denial: being fired for willful misconduct, quitting without good cause, or not being able to work due to illness or disability.

Weekly benefit amounts and work search requirements

Illinois calculates your weekly benefit amount based on your earnings in the highest-earning quarter of the year before you filed. The state's maximum weekly benefit is set each year and changes based on the state's average wage. As of 2024, the maximum is around $680 per week, but most people receive less depending on their prior income. IDES will tell you your specific amount in a letter after your claim is approved.

Once approved, you must file a weekly claim every week to receive your payment. You do this through the same IDES website or by phone. Each week, you report whether you worked, how much you earned, and whether you searched for work. Illinois requires you to make at least two work search contacts per week—this means explore for jobs, attending interviews, or contacting employers directly. You do not have to submit proof of your search, but you must be truthful about it. If you lie about work search activities, IDES can deny your claim and ask you to repay benefits.

Payments are deposited into a debit card account that IDES sets up for you, or you can choose direct deposit to your bank account. Most people receive their payment within two business days of filing their weekly claim.

What happens if IDES denies your claim

If IDES denies your claim, you will receive a letter explaining the reason. Common reasons include: you quit without good cause, you were fired for misconduct, or you did not meet the earnings requirement. Illinois requires you to have earned at least $1,600 in your highest-earning quarter in the year before you filed.

You have 30 days from the date of the denial letter to file an appeal. You do this by contacting the Illinois Department of Labor's Office of Unemployment Insurance Appeals at 1-800-244-5631 or through the IDES website. An appeals officer will review your case and may schedule a hearing. The appeals process usually takes four to eight weeks.

If you appeal, you can present new evidence or witnesses. For example, if you quit because your employer cut your hours, you can bring pay stubs showing the reduction. If you were fired, you can explain the circumstances and provide any documentation that supports your account.

Extended benefits and pandemic-related programs

Illinois offers Extended Benefits (EB) when the state's unemployment rate is high. Extended Benefits add up to 13 weeks of payments beyond your regular 26-week benefit period. You do not explore separately for Extended Benefits—IDES automatically enrolls you if you exhaust your regular benefits and the state's unemployment rate meets the threshold. The availability of Extended Benefits changes based on economic conditions.

Federal pandemic programs that were in place during 2020 and 2021 (such as Pandemic Unemployment information and Pandemic Emergency Unemployment Compensation) have ended. If you received those payments and IDES later determined you were ineligible, you may have been asked to repay the money. If you received an overpayment notice, you can request a waiver or payment plan through IDES.

Common mistakes to avoid when filing

Do not wait more than two weeks to file. Your benefit start date depends on when you file, and waiting costs you money. Do not lie about the reason you left work or about your work search activities. IDES verifies information with your employer and can cross-check your work search claims. If you misrepresent facts, you can be denied benefits and asked to repay what you received.

Do not ignore letters from IDES. If IDES asks you to verify information or attend a hearing, respond within the important date. Ignoring a request can result in your claim being denied. Do not forget to file your weekly claim. Missing even one week stops your payment for that week, and you cannot make it up later.

Do not report earnings incorrectly. If you work part-time while receiving unemployment, report it honestly. Illinois allows you to earn up to one-third of your weekly benefit amount without a reduction, but anything above that reduces your payment dollar-for-dollar. Underreporting earnings is fraud.

Frequently Asked Questions

Can I file for unemployment if I was fired?

You can file, but IDES will likely deny your claim if you were fired for willful misconduct—meaning you deliberately broke a rule or did something you knew was wrong. If you were fired for poor performance, inability to do the job, or a single mistake, you may be approved. The key is whether your employer can show you acted intentionally.

What if I quit my job?

Quitting usually disqualifies you unless you had good cause related to work. Good cause means your working conditions were unsafe, your pay was cut substantially, your hours were reduced significantly, or you faced harassment. Personal reasons like childcare problems or a long commute do not count as good cause. IDES will ask your employer why you left, so be prepared to explain your side.

How long do unemployment benefits last in Illinois?

Regular unemployment benefits last up to 26 weeks. If the state's unemployment rate is high, Extended Benefits may add 13 more weeks. You must continue to file weekly claims and meet work search requirements to keep receiving payments. If you return to work, your benefits stop.

Can I work part-time and still receive unemployment?

Yes. Illinois allows you to earn up to one-third of your weekly benefit amount without losing any payment. If you earn more than that, your benefit is reduced by the amount over the limit. For example, if your weekly benefit is $300, you can earn up to $100 without a reduction. If you earn $150, your benefit is reduced by $50.

What if IDES overpaid me?

If IDES determines you were overpaid—for example, because you did not report earnings or were ineligible—you will receive a notice asking you to repay the money. You can request a waiver if you received the overpayment without fault (meaning you did not cause the error) or if repayment would cause financial hardship. You can also request a payment plan instead of paying the full amount at once.
