Illinois Salary Guide 2026: Take-Home + Professions
Illinois has a flat 4.95% state income tax — clean, simple, no brackets, no Chicago city layer. The state tried twice (2014, 2020) to convert to a progressive structure; both ballot measures failed. The actual Illinois tax pain isn't income tax — it's property tax, which runs ~2.1% effective (#2 nationally behind NJ). Cook County and collar counties (DuPage, Lake, Will) produce $10-18K property tax bills on $400K homes. Retirement income is fully exempt. The post-2022 corporate exodus is real: Boeing left for Arlington VA, Caterpillar for Irving TX, Citadel HQ to Miami. Still in Chicago: McDonald's HQ, United Airlines HQ, CME Group + CBOE (the global derivatives capital), Northern Trust, the world's largest BigLaw firms (Kirkland & Ellis + Sidley), and Northwestern + Booth atop the business-school ladder.
Illinois take-home pay in 2026 at five common salary tiers
Single filer, federal standard deduction ($16,100), Illinois personal exemption ($2,425), zero 401(k) contribution, no HSA or FSA. 2026 federal brackets per Rev. Proc. 2025-32 + FICA. Illinois has no state standard deduction and no progressive brackets — the math is genuinely simple: take compensation minus personal exemption, multiply by 0.0495, that's your state tax. Chicago residents pay no additional city income tax (unlike NYC), which materially helps the bottom-line comparison vs NY.
| Gross salary | Take-home (single) | Note |
|---|---|---|
| $50,000 | $40,000 | ~$3,333/month. Comfortable in Peoria or Springfield; rent-tight in River North or Lincoln Park. |
| $75,000 | $58,000 | $4,830/month. Above-median income for Chicago metro; comfortable in West Loop, Logan Square, suburban DuPage. |
| $100,000 | $74,350 | $6,200/month. Roughly $1,500 less take-home than PA at the same gross; $4,830 less than TX or FL. |
| $150,000 | $106,486 | $8,870/month. Comfortable in Cook County north + DuPage suburbs. Property tax is the bigger budget item than state income tax at this tier. |
| $200,000 | $139,147 | $11,595/month. Add'l Medicare 0.9% kicks in above $200K. Chicago/Cook county property tax on a $500K home: $10-12K/yr. |
Married filing jointly uses doubled federal brackets + $4,850 IL exemption (one per spouse). Two-earner MFJ pays more FICA than the calculator shows because each spouse has their own Social Security wage base. The biggest hidden cost: property tax, which on a $400K Cook County home runs $8-12K/yr — often larger than the state income tax bill at this comp tier.
Where Illinois's highest salaries cluster — Chicago BigLaw, derivatives, healthcare
Chicago retains some of the densest BigLaw and derivatives compensation in the US despite the post-2022 corporate-HQ losses. The Loop + West Loop + River North together host the second-largest US BigLaw cluster after NYC, anchored by Kirkland & Ellis (the world's highest-revenue law firm).
Where Illinois pays the least — $15/hr state minimum, $16.20 Chicago
Illinois minimum wage is $15/hr (per 2019 SB1). Chicago citywide minimum is $16.20/hr. Tipped minimum is $9/hr with tip credit. Cost-of-living in Chicago is moderate by major-metro standards — well below SF/NYC/LA/Boston/DC but above Sun Belt comparables. Downstate IL (Peoria, Springfield, Rockford, Quad Cities) is among the most affordable US metros.
Illinois's economy — Chicago, the collar counties, and downstate
Chicago anchors Illinois's economy and accounts for ~70% of state GDP. The Loop + West Loop + River North host the densest US BigLaw cluster after NYC — Kirkland & Ellis (HQ Chicago, world's largest law firm by revenue ~$8B+ 2024), Sidley Austin (HQ Chicago ~2K attorneys), Mayer Brown, McDermott Will & Emery, Jenner & Block, Winston & Strawn. Chicago also remains the global derivatives capital — CME Group HQ (~3K), CBOE Global Markets, plus DRW, IMC, Jump Trading, Akuna Capital, Belvedere, Wolverine. Banking + asset management: JPMorgan Chase Chicago (~12K), Northern Trust HQ (~22K global), BMO Harris HQ, Discover Financial Riverwoods, Morningstar HQ. The 2022 corporate-HQ losses (Boeing to Arlington VA, Caterpillar to Irving TX, Citadel HQ to Miami) reshaped the prestige map. Still in Chicago: McDonald's HQ (~5K), United Airlines HQ (~80K global), Walgreens Boots Alliance HQ Deerfield (~315K global), Allstate Northbrook, Mondelez, Kraft Heinz, ADM, US Foods, W.W. Grainger.
The collar counties (Cook, DuPage, Lake, Will, Kane, McHenry) host the suburban Chicago economy. Lake County north shore (Lake Forest, Highland Park, Wilmette, Winnetka, Glencoe, Kenilworth) is among the highest-income corridors in the US — billionaire wealth, hedge fund principals, Fortune 500 executive housing. DuPage County (Naperville, Wheaton, Lisle, Downers Grove) anchors finance + tech suburbs — Tellabs heritage, Nicor Gas, BP America Naperville, Edward-Elmhurst Health system. McHenry + Kane + Will host manufacturing + logistics + agricultural fringe. The healthcare anchor across Chicagoland is enormous: Northwestern Memorial (~30K), Advocate Health post-2022 merger with Atrium SE (~150K combined across Chicago + Charlotte), Endeavor Health post-2024 NorthShore rebrand, RUSH, U of Chicago Medicine, Loyola, Lurie Children's, Cook County Health.
Downstate Illinois runs a different economy entirely. Springfield is state government + Memorial Health. Peoria + East Peoria still hosts Caterpillar manufacturing despite the HQ move (~5K IL manufacturing). Champaign-Urbana hosts UIUC (the world-class engineering + CS pipeline that feeds Bay Area tech) plus John Deere Champaign + Carle Health. Rockford has aerospace (Collins Aerospace, Woodward) + healthcare. Quad Cities (Moline + Rock Island IL + Davenport + Bettendorf IA) hosts John Deere HQ Moline + Arsenal Island military depot. Southern IL is rural agricultural (#2 US corn + soybean state behind Iowa). Illinois's pension-funding crisis is real and structural — the state has the worst-funded state pensions in the US, which puts ongoing upward pressure on property tax. Plan for property tax to keep growing 2-4% annually.
How Illinois tax shapes your actual take-home — the property-tax bite, not the income tax
Illinois's 4.95% flat state rate is genuinely simple — take compensation minus $2,425 personal exemption, multiply by 0.0495, that's the state tax. A $100K earner pays ~$4,830 in IL state tax. A $200K earner pays ~$9,780. No brackets, no SD, no progressive surtaxes on million-dollar income (unlike CA's MHST or NY's 10.9% above $25M). Chicago residents pay zero additional city income tax — a major advantage vs NYC where the combined NY+NYC stack at $100K is ~$8,700. Illinois tried twice (2014, 2020) to convert to a progressive structure via Constitutional amendment; both ballot measures failed. The flat structure is durable.
The actual Illinois tax pain isn't income tax — it's property tax. Illinois ranks #2 in the US at ~2.1% effective average, behind only New Jersey. Cook County effective rate is ~2.4%; DuPage County ~2.2%; Lake County (collar) ~2.5%; Will County ~2.4%. On a $400K Cook County home, that's $8,000-10,000/yr in property tax. On a $700K Naperville or Lake Forest home, $14,000-17,000/yr. For most IL homeowners earning $100-300K, property tax exceeds state income tax by a wide margin. The structural driver is the state's pension funding crisis — IL has the worst-funded state pensions in the US (Teachers Retirement System and State Universities Retirement System combined ~$140B unfunded liability), which puts continuous upward pressure on local property taxes funding pension contributions.
Retirement income is fully exempt at the state level — Social Security, public and private pensions, 401(k) distributions, IRA distributions are all IL-tax-free. Combined with the 4.95% flat rate during working years and no estate tax (IL repealed its estate tax in 2010, then reinstated above $4M in 2011 with current structure at $4M+), Illinois is surprisingly retirement-friendly for residents who can absorb the property tax bill. PA has a similar full retirement exemption + lower flat rate (3.07% vs 4.95%) + much lower property tax — making PA materially cheaper retirement-wise than IL despite IL's pension generosity to public retirees.
$100,000 in Illinois vs neighbor states — flat-rate, no-tax, and progressive comparisons
Single filer, $100,000 gross, no 401(k), federal standard deduction. IL personal exemption applied. Wage take-home only — IL's #2-in-US property tax shifts the homeowner math significantly against IL relative to most peers.
