Illinois unemployment payments are based on your past earnings, with a maximum weekly benefit that changes each year
Illinois calculates your weekly unemployment benefit by taking a percentage of your average earnings over a specific period in the past. The state does not pay a flat amount to everyone — your check depends on what you earned before you lost your job. The Illinois Department of Employment Security (IDES) looks at your wages from the first four of the last five completed calendar quarters before you file.
The maximum weekly benefit amount in Illinois changes annually on July 1. For 2024, the maximum is $744 per week. The minimum is $69 per week. Most people receive somewhere between these two numbers, depending on their prior wages. The benefit period lasts up to 26 weeks in a standard claim, though federal extensions have added weeks during certain economic periods.
Key Takeaways
- Your weekly benefit is roughly 47% of your average weekly wage from the past year, up to the state maximum of $744 per week as of July 2024.
- IDES uses your earnings from the first four of the last five completed calendar quarters to calculate what you earned on average.
- You receive benefits for up to 26 weeks in a standard claim, though this can extend if federal programs are active.
- Your benefit amount does not change week to week unless you report earnings from part-time work, which reduces your payment dollar-for-dollar above a small threshold.
How IDES calculates your weekly amount
The calculation starts with your base period — the four calendar quarters IDES uses to measure your earnings. If you file in March 2024, IDES looks back at your wages from January through December 2023. The state adds up all wages you earned during those four quarters, divides by 52 weeks, and then takes 47% of that average weekly wage. That result is your benefit amount, unless it exceeds the state maximum.
For example: if your average weekly wage was $1,000 over the base period, 47% of that is $470 per week. You would receive $470 weekly. If your average weekly wage was $1,600, 47% would be $752, but the state maximum is $744, so you would receive $744 instead.
The 47% replacement rate is set by Illinois law and does not change. What changes is the maximum benefit amount, which IDES adjusts each July based on the state's average weekly wage. This is why the maximum was lower in previous years and may be higher in future years.
What counts as earnings in your base period
IDES counts wages you received as a W-2 employee — the kind of income reported to the IRS on your tax return. This includes regular pay, bonuses, commissions, and vacation pay you actually received during the base period. It does not include tips, self-employment income, or money you earned as an independent contractor.
If you worked for multiple employers during the base period, IDES adds all of those wages together. If you received severance pay or a lump-sum payout when you were laid off, the timing of when you received it matters. If you received it during the base period, it counts toward your earnings. If you received it after the base period ended, it does not.
Wages you earned but did not yet receive — such as unpaid commissions or deferred compensation — do not count unless you actually received the money during the base period.
How part-time work or continued earnings reduce your benefit
If you work part-time or earn money while collecting unemployment, Illinois reduces your weekly benefit. The state allows you to earn up to $200 per week without any reduction. Anything you earn above $200 reduces your benefit dollar-for-dollar.
For example: if your weekly benefit is $400 and you earn $250 in a week, you report the $250. Your earnings above the $200 threshold are $50. Your benefit for that week is reduced by $50, so you receive $350 instead of $400. You still come out ahead by $200 that week ($350 benefit plus $250 earnings), but the benefit itself is lower.
You must report all earnings, including cash work, gig economy income, and any other money you received for work. IDES cross-checks this information with tax records and employer reports, so underreporting carries the risk of overpayment penalties and potential fraud charges.
Maximum and minimum benefit amounts by year
The maximum weekly benefit in Illinois has increased most years but not every year. The minimum has remained $69 per week for many years. Below is what the maximum has been in recent years:
| Year (effective July 1) | Maximum Weekly Benefit |
|---|---|
| 2024 | $744 |
| 2023 | $728 |
| 2022 | $720 |
| 2021 | $680 |
| 2020 | $680 |
The maximum adjusts based on the state's average weekly wage. If the state's average wage rises, the maximum rises. If it falls or stays flat, the maximum may stay the same. IDES announces the new maximum in June each year, effective July 1.
How to estimate your own benefit amount
To get a rough estimate before you file, gather your pay stubs or tax return from the past year. Add up all wages you earned in the four quarters that would form your base period. Divide that total by 52 to get your average weekly wage. Multiply by 0.47 (47%). If the result is higher than the current maximum, use the maximum instead.
This estimate is not official. IDES may calculate your base period differently if you have gaps in employment, if you worked for multiple employers, or if you received severance or bonuses. The only way to know your exact benefit amount is to file a claim with IDES. You can file online at ides.illinois.gov or by phone at 1-800-244-5631.
When you file, IDES sends you a notice of information that shows your calculated weekly benefit amount, your base period, and the wages IDES used in the calculation. If the amount seems wrong, you have 30 days to file an appeal and request a hearing to dispute it.
Federal extensions and additional weeks during recessions
The standard claim period in Illinois is 26 weeks. During recessions or periods of high unemployment, the federal government sometimes funds Extended Benefits (EB) or other temporary programs that add weeks beyond the standard 26. These programs are not always active.
When federal extensions are available, IDES notifies claimants automatically. You do not have to do anything to switch to the extended program — if you exhaust your 26 weeks and the extension is active, IDES continues your payments. The weekly amount stays the same; only the total number of weeks increases.
As of early 2024, no federal extensions are active in Illinois. This means new claims receive 26 weeks of benefits. If economic conditions change and extensions become available, IDES will announce it on their website and notify current claimants.
Frequently Asked Questions
Can I find out my benefit amount before I file a claim?
You can estimate it using your past year's wages, but IDES will not tell you the exact amount until you file. Once you submit a claim online or by phone, IDES sends a notice of information within one to two weeks that shows your calculated weekly benefit, your base period, and the wages used. If the amount surprises you, you can appeal within 30 days.
What if I was laid off but received a large severance payment?
Severance counts as wages if you received it during your base period. If you received it after your base period ended, it does not count. Either way, receiving severance does not disqualify you from unemployment. IDES will include it in the calculation if it falls within the base period dates.
Does my benefit amount change if I work part-time?
Your benefit amount itself does not change, but your weekly payment does. If you earn more than $200 per week, your benefit is reduced dollar-for-dollar for anything above that threshold. You must report all earnings each week. The reduction is temporary — it only applies to weeks when you earn above $200.
What happens if I reach the end of my 26 weeks?
Your claim ends and payments stop unless a federal extension program is active. If extensions are available, IDES automatically moves you to the extended program and continues payments. You do not have to reapply. If no extension is active, you would need to wait until you meet the requirements for a new claim, which typically requires working and earning wages again.
Can I appeal if I think my benefit amount is wrong?
Yes. You have 30 days from the date on your notice of information to file an appeal. You can appeal online through your IDES account or by mail. You will receive a hearing date, and you can present evidence of your wages — pay stubs, tax returns, or employer records — to support your case.
