How Illinois taxes income

A flat 4.95% applies at every income level in Illinois. There are no brackets to plan around — a raise is taxed at the same state rate as your first dollar, which makes the arithmetic unusually simple.

What actually reaches your account

Rough take-home at three common salary levels: $50,000 gross leaves roughly $38,700 after federal, FICA and $2,475 of Illinois tax; $80,000 gross leaves roughly $59,520 after federal, FICA and $3,960 of Illinois tax; $120,000 gross leaves roughly $85,680 after federal, FICA and $5,940 of Illinois tax. These use standard-deduction assumptions and no pre-tax contributions — a 401(k) or HSA lowers both federal and state tax and moves these numbers up.

Bracket tables are 2026 state rates; federal figures assume the standard deduction and no pre-tax contributions. See our methodology.
