Key Facts: Illinois Unemployment Insurance (2026)

TL;DR: Illinois pays unemployment benefits of $51 to $628 per week in 2026 — rising to a maximum of $748 with a non-working spouse and $859 with a dependent child. The weekly amount is 47% of the average weekly wage earned in your two highest base-period quarters. Qualifying takes at least $1,600 in base-period wages, including $440 outside your best quarter, and every eligible claimant receives the same 26-week duration (820 ILCS 405/401; IDES Table BEN 548).

Estimate Your Benefit

The estimator below applies the 2026 Illinois computation rules — the 47% two-quarter formula, the $1,600/$440 monetary thresholds, and the dependents’ allowance rates from IDES Table BEN 548 — to the wages you enter. The eligibility tab runs the monetary check in 820 ILCS 405/500(E).

How Much Is Unemployment in Illinois in 2026?

Illinois pays between $51 and $628 per week to claimants without dependents in 2026 (IDES Table BEN 548, effective January 1, 2026 (accessed July 5, 2026)). The weekly benefit amount is 47% of your average weekly wage, and Illinois defines that average as the wages paid in the two highest-earning quarters of your base period, divided by 26 (820 ILCS 405/401).

Worked example: $12,000 in your best quarter and $10,000 in your second-best quarter is a two-quarter total of $22,000. Dividing by 26 gives an average weekly wage of $846.15, and 47% of that is a weekly benefit of $398. The $628 maximum is itself 47% of Illinois’s statewide average weekly wage of $1,334.81, so it applies once your two-quarter total reaches roughly $34,705.

Two features distinguish the Illinois formula from most states’. First, it averages two quarters rather than using the single highest quarter (the method in Texas, New York, Florida, and California per the U.S. DOL, Significant Provisions of State UI Laws, January 2026), which softens the penalty for claimants whose earnings fluctuated. Second, because every dollar amount is recomputed each January from the statewide average weekly wage, the maximum rises automatically with Illinois wages — no legislative action required.

Dependents’ Allowances: How Illinois Pays Above Its Base Cap

Illinois adds 9% of your average weekly wage for a non-working spouse, or 17.3% for a dependent child, on top of the 47% base rate — lifting the 2026 maximum from $628 to $748 with a spouse and $859 with a child (IDES Table BEN 548 (accessed July 5, 2026)). State law pays one allowance or the other, not both, and the child allowance always pays more.

This is rarer than it sounds: computed from the DOL January 2026 table, only 13 of the 53 U.S. jurisdictions pay any dependents’ allowance at all, and most that do add a flat few dollars — Maryland pays $8 per dependent, Connecticut $15. Illinois’s percentage-based child allowance of up to $231 per week is among the largest in the country. Because each cap is a fixed share of the statewide average weekly wage (47%, 56%, and 64.4% respectively), all three maximums bind at the same earnings level: an average weekly wage of $1,334.81 or more.

Who Qualifies: Monetary Requirements

Illinois law sets two monetary thresholds: at least $1,600 in total wages during the base period, of which at least $440 must have been paid outside your highest-earning quarter (820 ILCS 405/500(E)). The base period is the first four of the last five completed calendar quarters before your claim. When wages in that window are insufficient, IDES re-runs the test using an alternate base period — the four most recently completed quarters — before denying a claim.

The $440-outside-the-top-quarter rule exists to screen out claimants whose entire work history sits in a single quarter; it is why the estimator above asks for two quarters. Illinois’s $1,600 floor is low by national standards — states like Washington require 680 hours of work, and Michigan requires at least $5,328 in the high quarter alone (U.S. DOL, January 2026).

Non-monetary requirements apply on top: the statute requires that you be unemployed through no fault of your own, able to work, available for work, actively seeking work, and registered with the state employment service (820 ILCS 405/500). IDES assesses these after you file, and reassesses them at every certification.

How Long Benefits Last

Illinois pays a uniform 26 weeks of regular benefits to every eligible claimant in 2026 — the duration does not scale down with your earnings history, as it does in most states (U.S. DOL, Significant Provisions, January 2026). Computed from that table, only nine U.S. jurisdictions pay a flat maximum duration to all claimants; elsewhere, weeks payable range as low as 9–12 in Florida and 8–20 in Missouri.

Your maximum benefit amount — the total your claim can pay — is the lesser of 26 times your weekly benefit (plus any dependents’ allowance) or your total base-period wages (U.S. DOL, January 2026). At the 2026 maximums, a full 26-week claim totals $16,328 with no dependents, $19,448 with a spouse allowance, and $22,334 with a child allowance.

How Illinois’s $628 Maximum Compares Nationally

As of January 2026, 19 states set a higher individual maximum weekly benefit than Illinois’s $628, and 30 states plus the District of Columbia set a lower one — placing Illinois 20th highest in the country (computed from U.S. DOL, Significant Provisions of State UI Laws, January 2026; dependents’ allowances excluded). The picture changes once dependents enter: at $859 with a child allowance, an Illinois claimant can out-collect the individual maximum of every state except Washington ($1,152), Massachusetts ($1,105), New Jersey ($905), Oregon ($872), New York ($869), and Hawaii ($868).

What Changed Recently

On January 1, 2026, IDES’s new benefit table (BEN 548, revised 11/2025) replaced the 2025 table (BEN 548, 11/2024), raising the individual maximum from $605 to $628 (+3.8%), the maximum with a non-working spouse from $721 to $748, and the maximum with a dependent child from $827 to $859. The driver is the statewide average weekly wage, which rose from $1,287.13 to $1,334.81 (+3.7%); each Illinois cap is a fixed percentage of that figure, so the maximums adjust automatically every January.

The monetary-eligibility thresholds did not change: $1,600 in base-period wages with $440 outside the highest quarter, both unchanged for over a decade. For context, California’s maximum has been frozen at $450 since January 2005, while Illinois’s has risen every year with its wage index — a structural difference in how the two statutes are written.

Filing a Claim and Staying Eligible

Claims are filed with the Illinois Department of Employment Security, online through the IDES unemployment insurance portal or by phone. A one-week unpaid waiting period applies to every new claim (820 ILCS 405/500(D)) — the first payable week is the second week you claim.

After filing, the statute requires certification every two weeks: you confirm for each week that you were able, available, and actively seeking work, and you report any earnings (820 ILCS 405/500). Registration with the state employment service at IllinoisJobLink.com is a condition of eligibility. If IDES denies a claim or sets an amount you dispute, state law provides 30 days from the mailing of the determination to file for reconsideration or appeal (820 ILCS 405/800).

Benefits are taxable twice over in Illinois: they count as gross income federally (26 U.S.C. §85) and, because the Illinois return starts from federal adjusted gross income, they are also taxed at the state’s flat 4.95% rate (35 ILCS 5/201). Claimants can elect withholding when filing; IDES issues Form 1099-G each January.

Frequently Asked Questions

What is the maximum unemployment benefit in Illinois in 2026?

$628 per week with no dependents, $748 with a non-working spouse, and $859 with a dependent child (IDES Table BEN 548, effective January 1, 2026 (accessed July 5, 2026)). Summaries citing “$748” as the individual maximum are quoting the spouse-allowance cap.

How is the Illinois weekly benefit calculated?

Take the wages from the two highest-earning quarters of your base period, divide by 26 to get your average weekly wage, then multiply by 47% (820 ILCS 405/401). A non-working spouse adds 9% of your average weekly wage; a dependent child adds 17.3%.

Is Illinois unemployment taxable?

Yes, at both levels: federally under 26 U.S.C. §85, and by Illinois at the flat 4.95% income-tax rate because state taxable income starts from federal AGI (35 ILCS 5/201). This differs from states like California, which exempts unemployment benefits from state income tax.

How long can I collect unemployment in Illinois?

26 weeks — the same for every eligible claimant. Illinois pays a uniform duration rather than scaling weeks to your earnings history, subject to a total cap equal to the lesser of 26 times your weekly benefit (plus allowances) or your base-period wages.

Do I qualify if I only worked part of the year?

Possibly: the thresholds are $1,600 in total base-period wages with at least $440 earned outside your highest quarter (820 ILCS 405/500(E)). If the standard base period falls short, IDES automatically re-checks using the four most recently completed quarters before denying the claim.

What We Verified

To build this page, we reviewed IDES Table BEN 548 (revised 11/2025, effective January 1, 2026), the prior BEN 548 table (revised 11/2024), the text of 820 ILCS 405/401 and 820 ILCS 405/500 on the Illinois General Assembly’s site, and the U.S. Department of Labor’s Significant Provisions of State Unemployment Insurance Laws (January 2026 edition), all accessed on July 5, 2026. The national ranking of Illinois’s $628 maximum was computed by RemoteLaws from the DOL table, excluding dependents’ allowances. Where secondary summaries claimed a $748 individual maximum for 2026, we verified against the official IDES table that $748 is the cap including the non-working spouse allowance; the individual maximum is $628.
