Illinois Unemployment Benefits 2026: Amount, Eligibility & How to Apply

Both of the following must be true of your base period:

• You were paid at least $1,600 in wages for insured work during the base period.
• At least $440 of those base-period wages were paid outside the calendar quarter in which your wages were highest.
• If you drew benefits on a prior claim, you must also have earned enough since then to qualify for a second benefit year.

Your standard base period is the first four of the last five completed calendar quarters immediately preceding the beginning of your benefit year.

In plain terms: IDES ignores the quarter you are in and the one right before it, then looks at the four quarters before that. A claim filed in August 2026 is built on wages from April 2025 through March 2026 — not on what you earned this summer. One Illinois warning worth heeding: once you file, you cannot withdraw the claim, even if filing a few weeks later would have produced a higher weekly amount.

Alternate base period: Yes, but only as a rescue. The alternate base period is the four most recently completed quarters, and Illinois will use it only if you do not qualify monetarily on the standard base period. It cannot be used simply to raise your weekly amount, so recent high earnings will not improve a claim that already qualifies.

You must be unemployed through no fault of your own. A layoff qualifies. Quitting disqualifies you unless you had good cause attributable to the employer — Illinois names specific exceptions including health, sexual harassment, domestic violence, unsuitable work, taking another job, and accompanying a relocating or military spouse. A discharge for misconduct connected with the work also disqualifies. If a quit or misconduct disqualification applies, it is not just for a few weeks: you have to work again and earn at least your weekly benefit amount in each of four calendar weeks, then lose that job through no fault of your own, before benefits can resume.

A layoff, a position elimination, and a reduction in force all sit squarely inside this test. If your employer contests the claim and calls it something else, that dispute is decided in the appeal process below — not by whichever word appears on your separation paperwork. The distinction matters enough to be worth understanding before the hearing: laid off vs fired, and why the label changes your claim.

For every week you claim you must have been willing, ready, and able to accept a suitable job — normally a full-time one. Illinois spells out what breaks it: being sick and unable to work on any day, being away on vacation, having to stay home to keep house or care for family, having retired and not being willing to take a suitable job, or insisting on wages, hours, or conditions that unreasonably limit your chances.

IDES takes the two calendar quarters of your base period in which you were paid the most, averages them into a weekly wage, and pays 47 percent of it. Dependents are handled separately: a non-working spouse adds 9 percent and a dependent child adds 17.3 percent, added on top of your weekly benefit amount rather than built into it.

The total you can draw in a benefit year is 26 times your weekly benefit amount, plus any dependent allowance. Illinois does not also cap the total at a fraction of base-period wages, so a qualifying claim generally runs the full 26 weeks unless you return to work.

You can earn up to 50 percent of your weekly benefit amount in a week before IDES reduces the payment. Above that, the excess comes off dollar for dollar. If your earnings for the week reach your full weekly benefit amount — before any dependent allowance — there is no payment for that week.

Take the part of your earnings that exceeds 50 percent of your weekly benefit amount and subtract it from your weekly benefit amount. If the result is not a whole dollar it is rounded up, and it can never exceed your full weekly amount. Any spouse or dependent-child allowance is added after that deduction, not before — so a partial week still carries the full dependent allowance.

Report gross wages — everything earned before deductions, including pay in the form of lodging, meals, or merchandise — for the week you did the work, not the week the money arrives. Report it even if you have not been paid yet. Holiday and vacation pay are treated differently and are deducted in full from that week's benefit.

Partial benefits are a reduction, not an exemption. You still have to certify on schedule, be able and available for full-time work, and keep looking for work. A part-time job does not switch off the work-search requirement or the record-keeping that goes with it.

Not sure what your weekly benefit amount is yet? The IDES determination is the figure that counts — for a rough, salary-based placeholder until it arrives, try the unemployment benefits estimator, then run the numbers above against it.

Illinois pays bi-weekly, for two calendar weeks at a time, and a calendar week runs Sunday to Saturday. When you file, IDES assigns you a certification day — Monday, Tuesday, or Wednesday. Miss it and you can still certify on Thursday or Friday, or wait and certify the following week. Certify online at IDES.Illinois.gov or through the Tele-Serve phone system. You are asked about any work you did, any vacation or holiday pay you received, and your work search, and you cannot be paid for weeks you have not certified for.

Deadline: Register with the Illinois Employment Service at IllinoisJobLink.com — or at an IDES office — as part of filing. Illinois states it flatly: registration must be complete before unemployment insurance benefits can be paid.

Illinois does not publish a fixed statewide number of contacts. The requirement is that you are actively looking for work on your own initiative each week, and that you can prove it. IDES may ask what you are doing to find work, what kind of work you are seeking, and what your prospects are.

What counts:

• Applying for jobs and recording when and where you applied.
• Searching and applying through IllinoisJobLink.com, which logs your activity automatically.
• Working with staff at an IDES office or a workNet Center on your job search.
• Interviews and employer contacts you initiate yourself.
• Approved training courses, where IDES has agreed they count.

Keep a written work-search record for every week you claim and do not discard it until 53 weeks have passed from the end of that week — Illinois can reconsider whether you were actively seeking work even after you have been paid or gone back to work. If an appeal is pending on a week, keep the record until the matter is finally resolved. Logging searches in IllinoisJobLink is the easy alternative.

Your appeal goes to an impartial Administrative Law Judge, called a referee, who schedules a hearing and notifies you of the date and time. You may be represented by a lawyer or anyone else you choose. Illinois contracts with law firms to provide limited free representation at appeal hearings — call 800-884-6591 as soon as you get a ruling against you, because the service is limited and delay can cost you the chance at it.

If the referee decides against you, you have 30 days from the date of that decision to appeal to the Board of Review, an independent five-person body appointed by the governor. After the Board of Review, the next step is judicial review in the circuit court.

Illinois draws a sharp line between severance and other separation money, and it works in your favor. The disqualifications IDES lists for a claimed week cover vacation pay, vacation allowance, stand-by pay for an announced shutdown, wages in lieu of notice, and back-pay awards — severance pay is not on that list. So a severance package generally does not postpone or reduce Illinois benefits, while a payout of accrued vacation, or pay covering a notice period your employer owed you, generally does for the weeks it covers. Report every separation payment when you file and let IDES classify it; the distinction is a legal one, not a judgment call.

Which category a particular payment falls into is the agency's call, not your employer's label for it: IDES claimant FAQs — what counts as wages against a week.

Report it either way. An unreported payment that the agency finds later becomes an overpayment you have to pay back, sometimes with a penalty — a far worse outcome than a delayed start. For how the two interact in general, and how timing a severance payment changes it, see severance and unemployment.

Illinois employers must pay final compensation at separation if possible, and no later than the next regularly scheduled payday (Illinois Wage Payment and Collection Act).

Check the figure before you cash it — unpaid commission, an expense reimbursement, or a promised bonus is easiest to raise while the separation is still fresh. The final paycheck calculator works out what you should be owed and when it is due.

Illinois requires the monetary equivalent of all earned, unused vacation to be paid at separation; a policy cannot make earned vacation forfeit on the way out.

Yes — the Illinois WARN Act requires 60 days' notice from employers with 75+ full-time employees for a mass layoff of 25+ workers (if they are a third of the site) or 250+, or a closing affecting 50+; penalties include back pay plus up to $500 per day.

Whether your layoff should have come with notice — and what happens if it did not — is set out in full in the Illinois WARN Act guide, along with the notices employers have actually filed in the state.

Unemployment benefits are taxable income in Illinois — federally and by the state. Withholding is voluntary and, if you elect it, IDES deducts 10 percent for federal income tax and 4.95 percent for Illinois income tax from each payment. You cannot change the deduction on a payment already made, so decide early rather than at tax time. You receive a 1099-G showing benefits paid and tax withheld.

Benefits arrive with no tax taken out unless you ask for withholding. Choosing 10% federal tax withholding can reduce the chance of an unexpected tax bill, but whether withholding makes sense depends on your individual tax situation — your other income for the year, your filing status, and any credits you expect. Confirm your own situation with a tax professional.
