File through IDES online, by phone, or by mail — but the online portal is fastest and most reliable

Illinois handles unemployment claims through the Illinois Department of Employment Security (IDES). You can file online at www.ides.illinois.gov, by phone at 1-800-244-5631, or by mail, but the online system processes claims faster and gives you when ready confirmation of what you submitted. You will need your Social Security number, driver's license or state ID number, and information about your most recent employer — including the company name, address, phone number, and the dates you worked there.

The state has no important date to file after losing your job, but your benefit amount is based on earnings from a specific 12-month period called the base period. The longer you wait, the older your earnings become, which can lower your weekly benefit. File as soon as you know you are unemployed and meet the basic requirements.

Key Takeaways

  • File online at www.ides.illinois.gov using your Social Security number and recent employer details; the system confirms your submission when ready.
  • You must have earned at least $1,600 in your base period (the 12 months before you file) and be unemployed through no fault of your own to receive benefits.
  • IDES will contact your former employer to verify the reason you left; if they say you quit without good cause or were fired for misconduct, you may be denied.
  • Weekly benefits range from $51 to $644 depending on your prior earnings, and the state currently pays up to 26 weeks of benefits per benefit year.
  • After you file, expect a information letter in the mail within two to three weeks; if you disagree with the decision, you have 30 days to request a hearing.

What you must have earned and why it matters

Illinois requires you to have earned at least $1,600 in your base period — the 12-month window that IDES uses to calculate your claim. The base period is usually the first four of the five calendar quarters before you file. For example, if you file in March 2024, your base period runs from January 2023 through December 2023. IDES looks at what you earned during that time, not what you earn after you file.

If you earned less than $1,600 in that 12-month window, you will not receive benefits, even if you lost your job through no fault of your own. If you worked for multiple employers during the base period, IDES adds all of that income together. Self-employment income, gig work, and contract work count only if you reported it on your tax return.

You must also have been unemployed through no fault of your own. This means you were laid off, your hours were cut, or your workplace closed. If you quit, you were fired for misconduct, or you refused work without good cause, you will be denied. IDES defines misconduct as deliberate or willful violation of reasonable employer rules — showing up late once is not misconduct, but a pattern of tardiness after warnings is.

How to gather what you need before you start

Before you open the online form, collect these documents and information. You will not upload them during filing, but you will need them to answer questions accurately, and IDES may ask for them later.

Write down your most recent employer's name, street address, city, state, zip code, and phone number. If you worked there under a different name or the company has moved, note that. Have your Social Security number and Illinois driver's license or state ID number ready. If you do not have an Illinois ID, your out-of-state driver's license works. Write down the exact dates you started and stopped working — month and year are enough, but day is better if you remember it.

If you were laid off or your position was eliminated, write down the reason in your own words. If your hours were cut, note how many hours you usually worked and how many you work now. If you quit, write down why — this is important because quitting for certain reasons (unsafe conditions, wage theft, domestic violence) may still may have access to you, while quitting to move or find a different job will not. Have this explanation ready when you file.

The online filing process step by step

Go to www.ides.illinois.gov and click the button to file a new claim. You will create a login account using your email address and a password you choose. IDES will send you a confirmation email — check your spam folder if you do not see it in your inbox.

The form asks for your personal information first: full name, date of birth, Social Security number, and contact details. Then it moves to employment history. Enter your most recent employer's information exactly as you have it written down. The system asks when you started, when you stopped, how much you earned per week, and why you are no longer working there. Answer the reason question as clearly as you can — "laid off due to lack of work" or "hours reduced from 40 to 20 per week" are clear; "company issues" is vague and may trigger a follow-up.

The form also asks whether you have worked for any other employers in the past 18 months. If you have, add them in order from most recent backward. You do not need to list every job you ever had, only the ones from the past year and a half. After you submit, the system shows you a confirmation number and tells you what IDES will do next. Write down the confirmation number.

What happens after you file and how long it takes

IDES sends your claim to your former employer for verification. The employer has about 10 days to respond with information about why you left, whether you were a good employee, and whether you are may be able to access for benefits. You will not see this exchange, but it shapes the decision IDES makes.

Within two to three weeks, you will receive a information letter in the mail. This letter says whether you are approved or denied, and if approved, it tells you your weekly benefit amount and how many weeks of benefits you can receive. Keep this letter — you will need it to claim your weekly benefits. If you are approved, you must file a weekly claim to actually receive payment; IDES will tell you how to do this in the letter or on the website.

If you are denied, the letter explains the reason. Common reasons are that you earned less than $1,600 in your base period, you quit without good cause, or you were fired for misconduct. You have 30 days from the date on the letter to request a hearing if you disagree. A hearing officer will review your case and your employer's response, and you can present your side of the story by phone or in writing.

How much you will receive and for how long

Illinois calculates your weekly benefit by taking your total base period earnings, dividing by 52, and paying you about 50 percent of that amount — with a minimum of $51 per week and a maximum of $644 per week. The exact amount depends on what you earned. If you earned $2,000 in your base period, your weekly benefit would be roughly $19, but Illinois rounds up to the $51 minimum, so you would receive $51. If you earned $30,000, your weekly benefit would be roughly $288.

The state currently pays up to 26 weeks of benefits per benefit year. A benefit year runs for 52 weeks starting from the week you file your claim. If you exhaust your 26 weeks and are still unemployed, you cannot file again until your benefit year ends and a new one begins. During recessions or periods of high unemployment, the federal government sometimes extends benefits beyond 26 weeks, but this is not automatic and requires a separate federal program.

What disqualifies you or reduces your benefits

You will be denied if you quit your job without good cause. Good cause means a reason that would make a reasonable person leave — unsafe working conditions, wage theft, harassment, or a substantial change in job duties. Wanting a different job, moving to a new city, or family reasons are not good cause. Your employer will tell IDES why you left, and if they say you quit, IDES will ask you to explain. If your explanation does not match the legal definition of good cause, you will be denied.

You will also be denied if you were fired for misconduct. Misconduct means you deliberately or willfully broke a reasonable employer rule. Being late once is not misconduct. Being late repeatedly after being warned is. Refusing a direct order, sleeping on the job, or stealing are misconduct. Poor performance, inability to do the job, or a personality conflict with your boss are not misconduct and do not disqualify you.

Your benefits will be reduced or stopped if you are working and earning money. Illinois allows you to earn up to a certain amount each week without losing benefits, but once you earn more than that threshold, your weekly benefit is reduced by the amount you earned over the limit. The exact threshold depends on your weekly benefit amount. If you return to work, report your earnings when you file your weekly claim.

If your claim is denied and you want to appeal

The information letter will include instructions for requesting a hearing. You have 30 days from the date on the letter. You can request a hearing by mail, phone, or online through the IDES website. You do not need a lawyer, but you can bring one if you want.

At the hearing, a hearing officer will ask you and your employer to explain what happened. You can present documents — a written job offer you turned down, a doctor's note about a medical condition that made work unsafe, text messages showing wage theft — anything that supports your side. The hearing officer will make a decision and send you a letter. If you disagree with that decision, you can appeal to the Illinois Unemployment Insurance Board of Review, but you must do so within 30 days of the hearing officer's decision.

Frequently Asked Questions

Can I file if I was fired?

Yes, but only if you were fired for reasons other than misconduct. If you were fired for poor performance, inability to do the job, or a mistake, you can receive benefits. If you were fired for deliberately breaking a rule, stealing, or refusing to follow instructions, you will be denied. Your employer will explain the reason to IDES, and you can dispute it at a hearing.

What if I quit because of a medical condition or family emergency?

Illinois recognizes certain reasons for quitting as "good cause." Medical conditions that make work unsafe or impossible, domestic violence, and caring for a seriously ill family member may may have access to. You will need to explain this clearly on your claim and provide documentation at a hearing if IDES denies you. A doctor's note or police report helps.

How do I claim my weekly benefits after I am approved?

Your information letter will tell you how to file weekly claims. Most people do this online through the IDES website or by phone. You must file every week you want to receive a payment, even if you do not work. The weekly claim asks whether you worked, how much you earned, and whether you are still unemployed. You file for the week that just ended, not the week coming up.

What if I move out of Illinois while receiving benefits?

You can continue to receive Illinois benefits if you move, but you must report the move to IDES and continue to file your weekly claims. Some states have reciprocal agreements with Illinois, meaning you can file your weekly claim in your new state. Contact IDES to ask about your specific situation.

Can I work part-time and still receive unemployment benefits?

Yes, but your benefit will be reduced based on what you earn. Illinois allows you to earn a certain amount each week without losing benefits, but once you exceed that amount, your weekly benefit is reduced dollar-for-dollar by the amount you earned over the limit. Report all earnings on your weekly claim, including gig work and self-employment income.
