The 2026 picture
Illinois Unemployment at a Glance
IDES indexes its benefit table to the statewide average weekly wage, which is why the ceiling has climbed steadily in recent years. Illinois also adds something many states dropped long ago: real money for dependents. A claimant with a non-working spouse or dependent children does not stop at the individual maximum.

What you would get
Illinois Weekly Benefit Amounts by Wage
The planning model behind this table pays about 47 percent of your gross weekly wage, then applies the state floor and ceiling. Find a wage close to yours and you will see the range to expect. Wages above roughly $1,287 per week all land on the same $605 cap, which is why a large share of Chicago-area professionals receive the maximum.
| Gross weekly wage | Estimated weekly benefit | Over 26 weeks | Where it lands |
|---|---|---|---|
| $300 | $141 | $3,666 | Within range |
| $500 | $235 | $6,110 | Within range |
| $800 | $376 | $9,776 | Within range |
| $1,100 | $517 | $13,442 | Within range |
| $1,400 | $605 | $15,730 | At state cap |
| $1,600 | $605 | $15,730 | At state cap |
Estimates use the 47 percent planning model. Your official IDES amount comes from quarterly wages, not weekly ones.
Do you qualify
The IDES Wage Tests Explained
Before IDES talks about money, it checks whether your work history clears two wage floors. Your base period is the first four of the last five completed calendar quarters when you file. Miss either floor and the claim stops there, so it pays to check yourself before you apply.
At least $1,600 in your base period
Add up every covered wage across the four base-period quarters. The total must reach $1,600. Seasonal and part-time workers clear this bar more often than they expect.
At least $440 outside your best quarter
Your highest-earning quarter cannot carry the whole claim. The wages you earned in the other quarters must total $440 or more, which rules out single-quarter work streaks.
Two-quarter wages of at least $800
The benefit table itself starts at $800 combined in your two highest quarters, which produces the $51 minimum check. Below that, no weekly amount exists to pay.
A qualifying reason and weekly availability
Money alone is not enough. You must be unemployed through no fault of your own, physically able to work, available for full-time work, and actively searching every claimed week.
Two Quarters In, Weekly Check Out
Illinois looks at your two strongest calendar quarters together, not just one. Combine them, divide by 26 to get an average weekly wage, and take 47 percent of that. These six combined totals show how the official method converts past wages into a weekly check.
| Two highest quarters combined | Estimated weekly benefit | 26-week pot |
|---|---|---|
| $8,000 | $145 | $3,770 |
| $12,000 | $217 | $5,642 |
| $16,000 | $290 | $7,540 |
| $20,000 | $362 | $9,412 |
| $26,000 | $470 | $12,220 |
| $34,000 | $605 — capped | $15,730 |
The window IDES looks through
Your Base Period: Four Quarters That Decide Everything
Every number in an Illinois claim flows from the base period, so it deserves a plain-English explanation. The standard base period is the first four of the last five completed calendar quarters before your claim week. The most recent finished quarter is skipped, and the current unfinished quarter does not exist for claim purposes.
| If you file in | Your standard base period covers |
|---|---|
| January through March 2026 | October 2024 through September 2025 |
| April through June 2026 | January 2025 through December 2025 |
| July through September 2026 | April 2025 through March 2026 |
| October through December 2026 | July 2025 through June 2026 |
A layoff that lands soon after a strong raise or a record quarter can look weaker than your real earnings, because those best months may fall outside the window. IDES built an answer for that. If the standard base period leaves you ineligible, IDES can substitute the alternate base period — the four most recently completed quarters — which pulls your newest wages into the calculation.
Money for your household
Spouse and Child Allowances Push Payments Higher
Illinois never abandoned dependents. On top of your weekly benefit, IDES pays a dependent allowance calculated from the statewide average weekly wage: 9 percent for a non-working spouse and 17.2 percent when dependent children rely on your income. The allowances stack on your base amount, subject to hard ceilings.
$605
Individual maximum
A claimant with no dependents stops here no matter how high the wages were.
$721
With a non-working spouse
Adds a 9 percent allowance — about $116 a week at the top of the table.
$827
With dependent children
Adds a 17.2 percent allowance — about $222 a week at the top of the table.
The spouse allowance requires a spouse who is not working and not substantially employed. The children’s allowance covers dependent children. You do not file a separate application: IDES builds the allowances into the monetary determination it mails after you file, so check that letter and call (800) 244-5631 immediately if eligible dependents are missing from the math.
Reason and conduct
Eligibility Beyond the Wage Tests
Passing the wage tests earns you a benefit amount, not a check. Separately, IDES examines why you lost the job and how you conduct yourself during the claim. The separation reason decides whether you qualify at all, and three weekly conditions decide whether each payment goes out.
Separations that usually qualify
Layoffs, plant closures, and documented hour reductions lead the list. Firings for genuine inability to meet performance standards often remain eligible, because Illinois reserves disqualification for misconduct connected to the work rather than weak output. Medical quits can qualify when the job posed a real health risk and you told the employer first.
Conduct that disqualifies
Misconduct means deliberate, willful acts against the employer’s interest: theft, violence, repeated documented rule violations after warnings, intoxication on the job. Quitting without good cause connected to the work also bars benefits. In Illinois the employer carries the burden of proving misconduct, not the other way around.
During the claim itself, every certification asks whether you are physically able to work, available for full-time work, and taking real steps to find it. Answering no to any one of them pauses that week, and a pattern of unavailable weeks can end the claim. Report any offer of suitable work too — refusing one without good cause affects eligibility the same way. Scan the full list of what can disqualify your benefits before certification day.
The official math
How IDES Calculates Your Weekly Amount
Illinois uses your two best calendar quarters together, which softens the blow of one weak quarter better than single-quarter states. The current unfinished quarter is skipped, the table applies 47 percent, and two hard clamps set the floor and ceiling. Five steps, no exceptions.
Identify your base period
IDES takes the first four of the last five completed calendar quarters before the week you file. If that window leaves you ineligible, IDES can review the alternate base period — the four most recently completed quarters.
Find your two highest quarters
Rank the four base-period quarters by wages paid and keep the top two. A $16,000 quarter plus a $12,000 quarter means the combined $28,000 is the only figure that matters next.
Divide by 26
The combined two-quarter wages are divided by 26. That number is your average weekly wage across the two quarters — the figure the 47 percent rate applies to.
Apply 47 percent and the clamps
Multiply the average by 0.47. Below $51 becomes $51. Above $605 becomes $605. Between those poles, the calculation stands as-is.
Add dependents, then multiply by 26
Spouse and child allowances join the weekly figure here, up to the $721 and $827 ceilings. Your maximum pot is simply 26 weekly checks, drawn down as you certify.
The formula IDES applies
Weekly benefit = (two highest quarters ÷ 26) × 47%, between $51 and $605

$1,100 every 2 weeks
Marcus registers on IllinoisJobLink.com the same week he files, because benefits cannot start until that registration is on file. His first certified week goes unpaid as the waiting week. If his non-working spouse later qualifies for the 9 percent allowance, roughly $105 more lands on each weekly check, and his weekly total still sits well under the $721 spouse ceiling.
Working while claiming
Part-Time Work and the 50 Percent Rule
Illinois lets you work part-time and still collect, and its earnings disregard is more generous than most states. IDES ignores the first 50 percent of your weekly benefit amount when it counts what you earned, then subtracts the excess dollar for dollar and rounds the payment up to the next whole dollar. Earnings at or above 150 percent of your benefit mean zero for that week — but you still certify, because the week keeps your claim alive.
| Part-time earnings that week | Benefit paid ($400 benefit example) | Why |
|---|---|---|
| $180 | $400 — full check | Under the $200 disregard (50% of $400), earnings are ignored |
| $350 | $250 | $350 minus the $200 disregard = $150 subtracted |
| $600 | $0 for the week | 150% of the benefit reached — no payment, but certify anyway to protect the claim |
Report every dollar you earn during certification, even unpaid promise-to-pay wages. IDES cross-matches wage records quarter by quarter, and unreported earnings surface months later as overpayment bills with penalties attached. Read how part-time work affects unemployment benefits for the full state-by-state picture.
Claim season
How to File Your Illinois Claim
Filing is free and online. Most Illinois claimants never visit an office, and the claim starts counting from the date you submit it — not the date you lost the job. File in your first week of unemployment; every week you wait is a week of benefits lost for good.
Gather your history
Your Social Security number, driver license or state ID, and employer details for the last 18 months: names, addresses, dates, wages, and the reason for separation. Have your preferred payment method ready too.
Set up ILogin and file online
Create your ILogin account, then file at the IDES benefits portal. The online application walks through your base-period employers one by one. Prefer paper or in-person help? Call (800) 244-5631 or schedule an office appointment at (217) 558-0401.
Register on IllinoisJobLink.com
Employment service registration is required before benefits can be paid, unless IDES exempts you. Upload a resume and confirm the registration — this single step blocks more first payments than any other.
Read your UI Finding letter
IDES mails or posts a determination showing your weekly benefit, dependents included, your certification day, and the wages it used. Disagree with the wage history? Appeal within 30 days of the mailing date.
The claim calendar
After You File: Waiting Week, Certify, Get Paid
Illinois claims run on a two-week rhythm. Every other week, on your assigned day, you certify: you answer a short set of questions confirming you were able to work, available, actively searching, and reporting any earnings. Certify online through your IDES account or by phone through Tele-Serve at 312-338-4337.
Payments usually land two to three business days after a clean certification. Curious about the full timeline from filing to first deposit? See when your first unemployment payment arrives, and make certification a calendar habit — missed certifications are the most common self-inflicted claim delay. Read how to certify for benefits without mistakes before your first request.
Keep the taxman unhurt
Taxes on Illinois Unemployment Benefits
Unemployment benefits are taxable income at both levels of government, and Illinois is one of the states that taxes its own benefits. The IRS counts every dollar as regular income, and Illinois applies its flat 4.95 percent state income tax rate. Expect a 1099-G form from IDES each January reporting the prior year’s total.
10%
Federal voluntary withholding
Elected at the pre-set IDES level; withheld before each payment.
4.95%
Illinois voluntary withholding
The flat state rate, withheld only if you elect it.
Withholding is voluntary but rarely wise to skip: no withholding means a possible April bill plus estimated-tax penalties. You can elect either or both when you file and change the election later through your IDES account. Plan the full picture with how unemployment benefits affect your taxes.
The standing requirement
Work Search Requirements in Illinois
Illinois has no fixed number of employer contacts written into its rulebook the way some states do. What the law requires is that you are able to work, available for full-time work, and actively seeking it every claimed week — and IDES backs that up with record checks. Keep a log of every application: employer name, date, and result.
The registration gate
Registration with Illinois Employment Services at IllinoisJobLink.com must be complete before benefits can be paid. It takes minutes: create the account, upload a resume, and confirm. Narrow exemptions exist, and IDES will tell you if yours applies.
The audit trail
Search while signed in to IllinoisJobLink.com and every application is logged automatically — the cleanest proof of compliance you can own. Offline applications belong in your own records, on IDES’s Work Search Record form if you like paper.
As unemployment stretches on, IDES expects flexibility about wages, hours, and commute, and it can refer you to reemployment services. Compare every state’s expectations in job search requirements that keep you eligible.
Fight the paperwork
Denied? The Illinois Appeal Ladder
Illinois gives you four rungs, and plenty of claimants win on the first or second. Every clock starts from the mailing date printed on the notice, so read that date first. Miss a deadline and the decision becomes final no matter how strong your evidence was.
| Level | Who decides | Deadline | What happens |
|---|---|---|---|
| 1 | Claims adjudicator | 30 days from mailing date | Written letter or Request for Reconsideration form to your local IDES office, by mail, fax, or delivery |
| 2 | Independent Referee | Hearing scheduled for you | Formal hearing with documents and witnesses; sworn testimony on the record |
| 3 | Board of Review | 30 days from the Referee decision | Written appeal using form APL124F with the docket number and your reasons |
| 4 | Circuit Court | 35 days from the Board decision | Appeal to the county circuit court where you lived when the decision issued |
File the first appeal even if you are still gathering evidence — the deadline does not wait, and hearings happen weeks later. Claimants who show up organized with documents and witnesses flip a meaningful share of first-level denials. Walk the full process with how to appeal a denied unemployment claim.
Avoid the classics
Six Mistakes That Delay Illinois Claims
Most Illinois claim problems trace back to a handful of preventable slips. Each one below has cost real claimants real weeks of benefits, and each takes five minutes to avoid.
Skipping the IllinoisJobLink registration
Benefits cannot start until the registration is on file. Do it the same day you file, before your first certification.
Missing the assigned certification day
Certify every two weeks on your assigned day. Miss it and payments stall; too many misses can close the claim. Tele-Serve at 312-338-4337 is the fallback if the site is down.
Under-reporting part-time earnings
IDES matches wage records quarter by quarter. Unreported earnings become overpayment bills with penalties — report every dollar, every week.
Not certifying the waiting week
The unpaid first week still must be claimed. Skip it and the whole claim queue jams behind a missing week.
Ignoring the UI Finding wage history
Employers make typos. If the wages on your determination look wrong, appeal within 30 days — a corrected wage history can change your whole benefit amount.
No payment method set before certifying
Paper checks ended July 8, 2026. Without direct deposit or debit card details on file, an approved week has nowhere to land.
