Illinois Unemployment Benefits 2026: $51 to $859 a Week

Illinois unemployment insurance isn't a grant or a needs-based benefit; it's insurance funded by employer contributions, paid to people out of work through no fault of their own. Filing is free through IDES's website or Claimant Services at 800-244-5631. If the first payment won't arrive before a bill does, our emergency cash assistance guide lists faster options.

Illinois Unemployment Benefits at a Glance (2026)

Illinois's $628 individual cap equals 47% of the statewide average weekly wage of $1,334.81 that IDES prints on its 2026 table, and DOL's January and July 2026 summaries show the same $51 to $77 minimums and $628 to $859 maximums. Here's the full picture:

Sources: IDES weekly benefit amount table (BEN 548, 11/2025) and benefit handbook; IDES certify and appeals pages; Illinois Department of Revenue IL-1040 instructions.

IDES sets the amounts for benefit years that begin on or after each January 1. The statute's determination dates fall once a year (there's no June 1 recalculation), so a claim filed in December 2026 still uses this table, and one filed in 2027 will use a new one.

How IDES Figures Your Weekly Benefit: The 47% Formula

Illinois uses your two best quarters. IDES takes the wages paid in the two base-period quarters in which you earned the most, divides by 26 (the weeks in two quarters) to get your prior average weekly wage, and pays 47% of that, rounded up to the next dollar, within the $51 to $628 range.

Worked example: a Rockford machinist with this specific base-period pay history, $50,000 in all:

1. Two best quarters: $13,000 + $13,000 = $26,000.
2. Prior average weekly wage: $26,000 ÷ 26 = $1,000.
3. Weekly benefit: 47% × $1,000 = $470, matching the IDES table row for $25,935 to $26,012.99.
4. With a dependent child: 17.3% × $1,000 = $173, so $643 a week.
5. Total for the claim: 26 × $470 = $12,220, or 26 × $643 = $16,718 with the child allowance.

To reach the $628 individual cap, your two best quarters have to total $34,697 or more, per the table's top row. The same $34,697 gets the spouse total to $748 and the child total to $859.

Your base period is normally the first four of the last five completed quarters. If that leaves you short, IDES checks an alternate base period made of the four most recent completed quarters. IDES says the alternate period can make you eligible but can't be used just to raise your weekly amount.

The Illinois Dependent Allowance

The allowance is the reason Illinois's top payment runs from $628 to $859. Grantsights analysis of the IDES table shows a child allowance at the top of the scale adds $231 a week, or $6,006 over 26 weeks, far more than Pennsylvania's $8 weekly maximum for dependents.

Grantsights calculation from the IDES weekly benefit amount table (BEN 548) for benefit years beginning on or after January 1, 2026.

The rules, per the IDES handbook:

• You can claim a spouse or a child, not both.
• A child must be your natural child, stepchild or adopted child (or in your custody by court order), under 18 or unable to work because of illness or disability, and you must have provided more than half of the child's support for the prior 90 days.
• A spouse counts only if they don't have enough wages to qualify for benefits themselves and you provided more than half of their support for the prior 90 days.
• IDES adds the allowance after any deduction for part-time earnings.

How Long Illinois Unemployment Lasts

Illinois is a uniform-duration state: everyone who qualifies can collect up to 26 weeks within a one-year benefit year, and the total is 26 times the weekly benefit plus any dependent allowance. The benefit year starts on the effective date of your first valid claim, usually the Sunday of the week you file, and runs a full year.

That makes Illinois more generous on length than states such as Florida (12 weeks in 2026) or North Carolina (12 weeks now), and the number doesn't shrink when the economy is strong. At the top, an Illinois claim with a dependent child can pay $22,334 (26 × $859). Federal extended benefits would only add weeks if unemployment rose far enough to trigger them.

Working Part Time on Illinois Unemployment

Illinois lets you keep earnings up to 50% of your weekly benefit amount before anything comes off. The excess is subtracted, and the partial amount is rounded up to the next dollar. Your earnings for the week must be less than your weekly benefit amount (not counting the dependent allowance) to get anything at all.

Example: a Peoria pharmacy tech with a $470 weekly benefit works one shift and earns $300 gross.

• Earnings disregarded: 50% × $470 = $235
• Excess: $300 - $235 = $65
• Payment: $470 - $65 = $405
• Total for the week: $405 + $300 = $705

If she also had a dependent child, the $173 allowance would be added on top, for $578. Holiday and vacation pay are different: IDES deducts the full amount from your weekly benefit. And if you're sick or otherwise unable to work on a workday, IDES cuts that week's payment by one-fifth for each such day.

Who Qualifies for Illinois Unemployment

IDES applies three tests.

1. Wages. At least $1,600 in base-period wages for insured work, with at least $440 paid outside your highest quarter.

2. Why you're out of work. Layoffs generally qualify. Quitting disqualifies you unless the reason is good cause attributable to your employer or one of the listed exceptions, such as health, sexual harassment, domestic violence, unsuitable work, accepting another job, or following a military spouse or a spouse relocating for work. Discharge for misconduct, or refusing suitable work without good cause, also disqualifies you. To requalify after any of those, you must earn at least your weekly benefit amount in each of four calendar weeks at a new job, then lose that job through no fault of your own. Discharge for a felony or theft connected with work can wipe out benefits based on wages up to the firing.

3. Every two weeks. Be able and available for full-time work and actively looking. Register with IllinoisJobLink.com; IDES won't pay a new claim until that registration is complete unless you're exempt. Keep a written record of every place you applied, and hold onto it until 53 weeks after the end of each week you claimed.

How to File and Certify in Illinois

IDES says a UI Finding letter arrives in roughly 7 to 10 business days after you file, showing your weekly benefit, base-period wages and your certification day.

1. File online with an ILogin account, or call 800-244-5631. To file in person, schedule an appointment at 217-558-0401.
2. Complete IllinoisJobLink registration and upload a resume.
3. Choose direct deposit when you file. Without it, IDES sends paper checks by mail, which is the default.
4. Be ready for an interview. IDES may schedule a phone interview based on your application, your answers or an employer protest; missing it without good cause can cost benefits.
5. Certify every two weeks on your assigned day, online from 3 a.m. to 7:30 p.m. or by Tele-Serve at 312-338-4337. Thursdays and Fridays are make-up days. The first eligible week is your unpaid waiting week.

How to Appeal an IDES Decision

Illinois gives you 30 days from the mailing date on a finding or determination to ask for reconsideration, per the IDES appeals page. Write a letter or use the Request for Reconsideration of Claims Adjudicator's Determination form, and mail, fax or deliver it to your local IDES office.

• If IDES doesn't reverse itself, the request goes automatically to the Appeals Division, and an administrative law judge (referee) holds a recorded phone hearing.
• Exhibits: send them to the referee and the other side at least 24 hours before the hearing.
• Missed the hearing? Ask to reopen it within 10 days.
• Board of Review: appeal the referee's decision within 30 days, in writing or with form APL124F. After that comes circuit court, with no court costs for claimants.

The state contracts with law firms to offer limited free representation at IDES hearings. Keep certifying every two weeks while you remain unemployed and the appeal is pending.

Taxes on Illinois Unemployment Benefits

Illinois benefits are taxed by the IRS and by Illinois. IDES withholds at fixed levels if you ask: 10% federal and 4.95% Illinois. According to IRS Form W-4V, 10% is the only federal withholding rate allowed for unemployment payments.

According to the Illinois Department of Revenue's 2025 IL-1040 instructions (opens in a new tab), the Illinois income tax rate is 4.95%, and the instructions list Illinois unemployment income as taxable even for residents of the four states with wage reciprocity agreements. IDES posts your 1099-G in your account and mails paper copies by the first week of February. If you got a 1099-G and never filed a claim, call IDES at 800-244-5631; confirmed fraud victims aren't held responsible for the benefits or the taxes.

What IDES Doesn't Tell You

Grantsights compared IDES's table and handbook with the statute and DOL's tables, and five points stand out:

1. A child is worth more than a spouse. The child allowance (17.3%) is almost twice the spouse allowance (9%), and you can only claim one. If both apply, claiming the child pays better than claiming the spouse.
2. Your filing year locks your table. The 2026 amounts apply to benefit years starting in 2026. A claim started in late December keeps the 2026 maximum all year; one started in January 2027 uses whatever table IDES publishes then.
3. Paper checks are the default. IDES mails checks unless you choose direct deposit, which slows the first payment for anyone who skips that step.
4. Missing an interview call is costly. If you're not at the number you gave IDES at the scheduled time, you can lose benefits for the weeks at issue.
5. Overpayment recovery is capped. For non-fraud overpayments, IDES can take no more than 25% of your weekly benefit from each payment, and you can ask for a hardship waiver of recoupment.

Common Mistakes and Red Flags

The most common mistake is missing your certification day and forgetting the make-up days. IDES pays only for weeks you've certified, and Thursday and Friday are the backup.

More mistakes that cost Illinois claimants:

• Quitting instead of waiting for a layoff. A quit outside the listed exceptions blocks benefits until you requalify over four weeks of new work.
• Not reporting part-time pay. IDES cross-checks earnings, and IDES lists unreported part-time and odd-job earnings among the most common mistakes.
• Claiming a spouse and a child. Only one allowance is allowed.
• Underestimating fraud penalties. False statements can bring fines, jail and comptroller offsets of state and federal tax refunds.
• Skipping IllinoisJobLink. A new claim isn't paid until registration is complete.

Red flags: filing with IDES is free, and IDES's official address is ides.illinois.gov. Report anyone charging to file or asking for your ILogin password.

Worked Examples: Three Illinois Claims

These are hypothetical Illinois workers with 2026 benefit years:

For example, a Chicago paralegal earned $20,000 in each of her two best quarters ($40,000). That's well above $34,697, so she's at the $628 cap, and with her 10-year-old daughter as a dependent, $859 a week, or $22,334 over 26 weeks.

A Springfield warehouse worker earned $9,000 and $9,500 in his best quarters. $18,500 ÷ 26 = $711.54, which IDES rounds to a $712 average weekly wage; 47% of that, rounded up, is $335 a week. His wife doesn't work and he supports her, so the table adds $65 for $400, or $10,400 over 26 weeks.

A part-time cashier in Aurora earned $2,200 and $2,000 in her best quarters and $5,600 total. She clears the $1,600 and $440 tests. Her average weekly wage rounds to $162, and the IDES table pays $77 a week for up to 26 weeks, or $2,002 in all.

Other Help in Illinois While You Wait

Benefits replace about half of a typical paycheck at most. Also check:

• Illinois food stamps (SNAP); benefits count as income, but many claimants still qualify.
• Illinois Medicaid income limits if job-based health coverage ended.
• LIHEAP in Illinois for winter heating bills, and the rental assistance programs guide for rent.
• Worked in another state? Compare Ohio unemployment benefits, Washington unemployment benefits and Pennsylvania unemployment benefits.

For food, utility and housing help in the same search, the Grantsights free eligibility checker lists official Illinois programs to look into. IDES alone decides unemployment claims, and the checker doesn't file anything for you.
