Understanding Illinois Unemployment Insurance Basics

Illinois unemployment insurance is a program that provides temporary income support to workers who have lost their jobs through no fault of their own. The program is funded through employer payroll taxes, not general tax dollars. Workers who meet certain requirements may receive weekly payments while they search for new employment.

The Illinois Department of Employment Security (IDES) administers the unemployment insurance program. This agency processes claims, determines who may receive benefits, and sends weekly payments to those who are approved. In 2023, IDES processed over 2.5 million claims and distributed approximately $6.8 billion in benefits to Illinois workers.

Unemployment insurance in Illinois works on a weekly basis. If you lose your job, you can file a claim that covers a specific week of unemployment. You must then certify your status each week — meaning you confirm that you were unemployed during that week and that you met all program requirements. This weekly certification process is what this guide focuses on.

The maximum weekly benefit amount in Illinois ranges based on your previous earnings, with amounts ranging from $51 to $895 per week as of 2024. However, the actual amount you may receive depends on your work history and earnings in the year before you filed your claim. Benefits are typically available for up to 26 weeks in a benefit year, though federal programs sometimes extend this period during economic downturns.

Understanding the difference between filing a claim and certifying for benefits is important. Filing a claim is the initial step where you provide information about your job loss. Certification is the ongoing process you repeat each week to confirm you remain unemployed and meet the program's requirements.

Practical Takeaway: Unemployment insurance provides temporary income during job loss and requires weekly certification to continue receiving payments. Learn the basic structure of how the program works before moving forward with certification.

Who May Receive Illinois Unemployment Certification

Not all job losses result in unemployment insurance benefits. Illinois law specifies certain conditions that must be met. Generally, you may receive benefits if you lost your job through no fault of your own — meaning you did not quit, were not fired for misconduct, and were not self-employed.

Common situations where workers may receive benefits include: company layoffs, position elimination, business closure, lack of work, and reduction in hours. You must also have worked in Illinois and earned sufficient wages during the "base period" — typically the first four of the five calendar quarters before you filed your claim.

Earnings requirements vary, but you generally must have earned at least $1,600 during your base period, with at least $400 in one quarter. This ensures that only workers with meaningful employment history in Illinois are covered by the program.

Certain workers face restrictions on receiving benefits. These include: workers who quit their job without good cause, workers fired for willful misconduct, workers involved in labor disputes, workers receiving workers' compensation or temporary disability, and workers who have not worked enough to meet wage requirements. Additionally, if you are in school full-time, under 16 years old, or self-employed, different rules may apply.

To certify for benefits each week, you must meet these requirements during that specific week: be totally or partially unemployed, be able and willing to work, be actively looking for work, and report any wages you earned. If any of these conditions change during the week, it may affect your certification and the benefits you receive.

Non-citizens may also receive unemployment benefits if they have work authorization in the United States. Your immigration status does not prevent you from filing a claim or certifying for benefits — only your legal right to work in the country matters.

Practical Takeaway: Review the basic requirements for receiving benefits in Illinois before beginning weekly certification. If you quit your job, were fired for misconduct, or have not worked enough, you may not be able to certify for benefits.

The Weekly Certification Process in Illinois

Once you have filed an initial claim with IDES, you must certify each week to continue receiving payments. Certification is your way of telling the state that you were unemployed during a specific week and that you met all program requirements. Without weekly certification, IDES will not send you a payment for that week.

Illinois offers three ways to certify: online through the IDES website, by phone using an automated system, or by mail using a paper form. Most workers use the online method because it is available 24 hours a day, 7 days a week, and you receive immediate confirmation when you complete it.

To certify online, you log into your IDES account using your Social Security number and PIN (or password). You then answer questions about your employment status during the week you are certifying. The questions ask whether you worked, whether you earned any wages, whether you looked for work, and whether anything else happened that might affect your benefits.

The certification period typically runs from Sunday through Saturday. You can certify for the previous week starting on Sunday and should complete certification by the following Friday to avoid payment delays. IDES sends payments on Friday or Saturday of the following week to accounts you have on file, so timely certification matters.

If you worked during the week, you must report your gross wages (before taxes) for that week. Partial unemployment benefits are available in Illinois, meaning you can work part-time and still receive a reduced benefit payment. The amount of your benefit decreases based on how much you earned that week.

Important information to have ready when you certify: your Social Security number, PIN or password, information about any work you performed, wages you earned, and details about your job search activities. Keep records of where you applied for jobs and any contacts you made with employers.

Practical Takeaway: Certify weekly through the method that works best for you — online is fastest — and report all wages earned that week. Late certification can delay your payment by one or more weeks.

Information You Need to Provide During Certification

When you certify each week, IDES asks specific questions designed to determine if you remain unemployed and are meeting program requirements. Understanding what information to prepare ahead of time makes the process faster and reduces errors.

The first set of questions covers your employment status. You will be asked if you were employed during the week, worked any days, and if so, how many. Be honest about part-time work, temporary work, or any hours you worked. Working even one day affects your certification for that week.

Wage information is the next major area. You must report your gross wages — the total amount earned before taxes or deductions — for any work performed during the week. This includes tips, bonuses, commissions, and any other compensation. If your employer has not yet paid you for work performed, you still report those wages in the week you performed the work, not when you receive payment.

You will be asked about your job search activities. Illinois requires that you are actively looking for work while receiving benefits. You should be prepared to describe: companies you contacted, job applications you submitted, interviews you attended, or employment agencies you registered with during the week. Write down these activities throughout the week so you have accurate information when you certify.

Additional questions may ask about: receipt of other income (severance, vacation pay, bonuses), receipt of benefits from other programs (workers' compensation, disability insurance), whether you are in school, whether you attended any training programs, and any other circumstances that might affect your benefit status.

Be completely truthful when certifying. False statements about your employment status, wages, or job search activities are considered fraud. IDES uses computer matching and employer reports to verify the information you provide. If you misreport information, you may be required to repay benefits and could face legal penalties.

If you are unsure about how to answer a question — for example, whether certain income counts as wages — leave a note or contact IDES before certifying. It is better to ask for clarification than to provide incorrect information.

Practical Takeaway: Keep a weekly log of work performed, wages earned, and job search activities. Have this information ready before you sit down to certify each week.
