$80K a Year in Illinois: What You Take Home After Taxes
A single filer earning $80,000 in Illinois keeps $61,236 in 2026 — $5,103 a month, $2,355 per biweekly paycheck — after $8,825 of federal income tax, $6,120 of Social Security and Medicare, and $3,819 of Illinois state income tax. That is 23.5% in total tax, ranking Illinois #43 of 50 states at this salary.
How Illinois taxes $80,000, band by band
Illinois starts from $80,000 of income and subtracts its own standard deduction of $2,850, leaving $77,150 of state taxable income. Every dollar of that is taxed at the flat 4.95% rate. The state tax comes to $3,819 — an effective state rate of 4.8% against a marginal rate of 5.0% on the next dollar.
| Illinois bracket (single) | Rate | Your income in this band | Tax on this band |
|---|---|---|---|
| Over $0 | 4.95% | $77,150 | $3,819 |
| Total Illinois income tax | $77,150 | $3,819 | |
Deductions and credits in Illinois
Illinois has no standard deduction and no itemized deductions; the only universal subtraction is a personal exemption a little under $3,000 per taxpayer and dependent, plus $1,000 for filers 65 or older or blind, and it disappears above $250,000 of adjusted gross income single or $500,000 joint. Credits carry the weight: a state earned income credit worth 20% of the federal credit, a child credit for EITC recipients with children under 12, a 5% credit for property taxes on a principal residence, and a K-12 education expense credit of up to $750.
Local income taxes in Illinois
Illinois has no local income taxes. The Illinois Constitution bars home-rule units, including Chicago, from taxing income, earnings or occupations without General Assembly authorization, and none has been granted. Chicago instead leans on the nation's highest big-city sales tax, a 9% amusement tax, and utility and parking taxes. Suburban Cook County and the collar counties add nothing to paychecks.
The federal side of $80,000
Federal tax is the same in every state. After the $16,100 standard deduction, $80,000 becomes $63,900 of federal taxable income and owes $8,825 of income tax (11.0% effective). Social Security takes $4,960 and Medicare $1,160. Before any state tax, that leaves $65,055 — the figure a Illinois worker would keep by moving to Texas or Florida, $3,819 more than staying put.
| Gross salary | $80,000 |
| Federal income tax | −$8,825 |
| Social Security (6.2%) | −$4,960 |
| Medicare | −$1,160 |
| Illinois state tax | −$3,819 |
| Take-home pay | $61,236 |
Married filing jointly on $80,000 in Illinois
The same $80,000 of household income on a joint return keeps $64,962 in Illinois — $3,726 more than a single filer. Illinois uses the same brackets for joint and single filers, so the state-level marriage bonus comes only from the larger joint deduction; the federal side supplies most of the gap.

What $61,236 buys in Illinois
Illinois's cost-of-living index is 93 (7% below the national average), so $61,236 of take-home has the purchasing power of about $65,845 in an average-cost area. The 30% guideline caps rent at $2,000 a month on this salary. $80,000 is 23% above Illinois's median household income of $65,000, which itself nets $51,331 after tax. A $10,000 raise from here keeps $6,540 after federal and Illinois tax.
Who earns $80K in Illinois, and what to do with it
$80,000 is typical of mid-career accountants and financial analysts, experienced registered nurses, mechanical and civil engineers a few years in, IT administrators, high-school teachers with a master's degree in higher-paying states, and skilled-trades foremen. It is $38.46 an hour and lands at roughly the 70th percentile of individual full-time earners — a solid single income in most of the country.
Every raise from $80,000 up is taxed at 22% federally plus state tax, so this is where pre-tax saving pays off clearly: maxing a 401(k) at $24,500 would drop a single filer's taxable income by nearly a third and save well over $5,000 in federal tax alone. For couples, a second income at $80,000 pushes joint taxable income toward the top of the 22% bracket; a dual-earner household should model contributions jointly rather than separately.
Retirees are Illinois' clearest winners: pensions, IRAs and Social Security are entirely untaxed. High W-2 earners do better than the 4.95% headline suggests next to Wisconsin (7.65% top) or Minnesota (9.85%), and there is no local tax in Chicago. Dual-income couples pay a flat rate with per-person exemptions, so marriage changes nothing. Remote workers owe 4.95% on all wages earned while living in Illinois; reciprocity with Iowa, Kentucky, Michigan and Wisconsin covers cross-border commuters. Homeowners lose: the property tax bill on a modest house often exceeds the state income tax.
