How Illinois unemployment benefits are calculated

Illinois sets your weekly benefit amount (WBA) using wages from your base period — usually the first four of the last five completed calendar quarters. Many states use your high-quarter wages divided by 26, then capped between the state minimum and maximum. Official determinations may differ.

Using annual salary ÷ 4 as estimated high-quarter wages ($12,500), this calculator estimates about $480/week in Illinois — roughly $12,480 over 26 weeks. Enter your real high-quarter wages above for a tighter estimate.

At $75,000 (HQ ≈ $18,750), the estimate is about $721/week ($18,746 over 26 weeks). At $100,000 (HQ ≈ $25,000), about $859/week ($22,334 over 26 weeks) at the state max. Higher salaries often hit Illinois's $859 weekly cap.

Illinois typically sets your weekly benefit amount from base-period wages. A common approximation is high-quarter wages ÷ 26, then capped between $51 and $859 per week. This Illinois unemployment calculator applies that estimate instantly — your state agency’s official determination may use a different divisor, dependents, or alternate base period.

Illinois generally allows up to 26 weeks of regular unemployment benefits, subject to eligibility, certification, and state law. Some durations can vary with the state unemployment rate. Extended or emergency federal programs (when active) can add weeks beyond the regular maximum.

File with Illinois's unemployment insurance agency as soon as you become unemployed — most states accept online claims. Have your Social Security number, ID, recent employer names/addresses/dates/wages, and reason for separation ready. Illinois will verify wages and set your official WBA; this page only provides an estimate.

Yes for federal income tax — UI is ordinary taxable income nationwide in 2026. You can often elect 10% federal withholding with Form W-4V. State income-tax treatment of UI varies; confirm whether Illinois taxes unemployment benefits with your state tax agency. UI also increases MAGI and can affect ACA premium tax credits.

The base period is usually the first four of the last five completed calendar quarters before you file. Your high quarter is the single highest-earning quarter in that period — the key input many states use for WBA. If recent wages are higher (raise or new job), ask whether Illinois applies an Alternate Base Period (ABP) that includes more recent quarters.

This calculator uses a common high-quarter ÷ 26 approximation capped at Illinois's published min/max ($51–$859/wk). Illinois may use a different formula, dependency allowances, partial-week reductions, or waiting-week rules. Always rely on your claim determination from Illinois's UI agency.
