Salary Calculator Illinois — Take-Home Pay After 4.95% Flat Tax 2026
Your offer letter says $75,000. Your colleague in Texas takes home more. Your friend in California takes home less. Illinois sits somewhere in the middle — but the flat 4.95% tax rate, no local city tax, and full retirement income exemption make it more predictable than almost any other state.
Illinois is simpler than most states — one flat rate, no city tax — but the retirement income exemption and reciprocal state rules are where most salary calculators stop short. This one doesn’t.

How Illinois Salary Tax Calculator Works — The Flat Rate Explained
Illinois Flat Tax — 4.95% on Every Dollar
Illinois is one of only a handful of states with a constitutionally mandated flat income tax. Every Illinois resident pays exactly 4.95% of their taxable income in state income tax — whether they earn $25,000 or $2,500,000. There are no progressive brackets, no phase-outs, and no higher rates for higher earners.
This is mandated by the Illinois Constitution, which requires that income taxes be levied at a uniform rate. In 2020, Illinois voters rejected a proposed amendment that would have allowed a graduated income tax structure. The flat rate remains.
Illinois Personal Exemption — $2,925 in 2026
Before the 4.95% rate is applied, Illinois subtracts a personal exemption from your gross income. For 2026, this exemption is $2,925 per person. For a single filer, your taxable Illinois income is your gross income minus $2,925.
Example: $65,000 gross salary
- Minus personal exemption: $2,925
- Illinois taxable income: $62,075
- Illinois state tax: $62,075 × 4.95% = $3,073
The exemption increases for dependents and for taxpayers who are 65 or older or legally blind, reducing the taxable base further.
No Local Income Tax Anywhere in Illinois
Unlike New York City (3.876% city tax) or Philadelphia (3.75% wage tax), no city or county in Illinois charges a local personal income tax. Chicago, Springfield, Rockford, Peoria — none of them add a local income tax layer on top of the state rate.
This is one of the most misunderstood aspects of Illinois taxation. Workers who move from Ohio cities (where local rates of 2–3% are common) or Philadelphia often expect a Chicago city tax and are pleasantly surprised to find none exists.

Illinois vs Other States — Annual Take-Home Comparison
At $80,000 salary, single filer — what do you keep?
| State | State Tax Structure | Annual Take-Home |
|---|---|---|
| Texas | No state income tax | ~$63,400 |
| Florida | No state income tax | ~$63,400 |
| Illinois | 4.95% flat | ~$60,237 |
| Colorado | 4.40% flat | ~$60,800 |
| Michigan | 4.25% flat | ~$61,100 |
| New York | Up to 6.85% progressive | ~$58,200 |
| California | Up to 9.3% progressive | ~$56,900 |
Illinois workers keep approximately $3,200 less per year than Texans at $80,000 — but $1,300–$2,300 more than New Yorkers or Californians at the same income. The flat rate makes Illinois a middle-ground state for income tax purposes.
What Gets Deducted From Your Illinois Paycheck
Federal Income Tax — 2026 Brackets
Federal income tax is progressive and applies to all US employees regardless of state:
| Taxable Income (Single) | Rate |
|---|---|
| $0 – $12,400 | 10% |
| $12,401 – $50,400 | 12% |
| $50,401 – $105,700 | 22% |
| $105,701 – $201,775 | 24% |
| $201,776 – $256,225 | 32% |
| Over $256,225 | 35–37% |
Standard deduction 2026: $16,100 (single) / $32,200 (married filing jointly)
FICA — Social Security and Medicare
- Social Security: 6.2% up to $184,500 wage base (2026)
- Medicare: 1.45% on all wages
- Additional Medicare Tax: 0.9% on wages above $200,000 (single filers)
Illinois does not have a state disability insurance contribution (unlike California’s SDI at 1.1%), which slightly increases take-home relative to California workers.
Illinois State Tax — The Flat 4.95%
After subtracting your $2,925 personal exemption, multiply your remaining income by 4.95%. No brackets. No additional exemptions based on filing status at the state level (unlike federal). The calculation is the same for single, married, and head of household filers at the state level.

Chicago vs Downstate Illinois — Wage Differences
Illinois minimum wage is $15.00 per hour statewide as of 2026. Chicago has its own minimum wage, currently $16.60 per hour for employers with 4 or more employees (adjusted annually each July 1). The Chicago minimum wage applies within city limits — not Cook County suburbs.
For take-home purposes, state and federal taxes apply identically in Chicago and downstate Illinois. The only wage difference is the minimum wage floor — no Chicago city income tax exists to calculate.
Illinois Reciprocal States — Working Across State Lines
Illinois has reciprocal income tax agreements with four neighboring states: Wisconsin, Michigan, Iowa, and Kentucky. Under these agreements:
- If you live in one of these four states but work in Illinois, you pay income tax only to your home state — not to Illinois.
- If you live in Illinois but work in one of these four states, you pay Illinois income tax only.
Practical example: A Michigan resident who commutes to Chicago pays Michigan income tax (4.25%) on their Illinois wages, not Illinois tax (4.95%). They save 0.70% of their income annually and file a non-residency exemption (IL-W5-NR) with their Illinois employer.
If you work in Illinois but live in a non-reciprocal state (Indiana, Missouri, Ohio, etc.), you file in both states — but most states provide a credit for taxes paid to another state, so you generally don’t pay double.
Illinois Retirement Income — Fully Exempt from State Tax
One of Illinois’s most significant and least-advertised tax features: all retirement income is fully exempt from Illinois state income tax. This includes:
- Social Security benefits
- 401(k) distributions
- IRA withdrawals (traditional and Roth)
- Pension income (public and private)
- Annuity payments from retirement plans
A retired Illinois resident receiving $50,000/year in Social Security and 401(k) distributions pays zero Illinois state tax on that income. The federal government may still tax a portion of Social Security depending on total income — but Illinois does not.
This exemption makes Illinois one of the most retirement-friendly states for income purposes — even though property taxes are among the highest in the nation.
Illinois Salary Calculator for Chicago Workers
Chicago workers should note that while there is no city income tax, Chicago has several indirect costs that affect net compensation:
- Chicago sales tax: 10.25% combined (state + county + city) — one of the highest in the US
- Chicago property taxes: among the highest nationally for Cook County homeowners (see our Illinois Property Tax Calculator)
- Parking, restaurant, and amusement taxes add to living costs
- Transportation: CTA fares and parking costs
For salary negotiation purposes in Chicago: account for the higher cost of living relative to downstate Illinois. A $75,000 salary in Chicago and a $75,000 salary in Peoria have the same state and federal tax treatment — but very different real purchasing power.
Illinois 401k Treatment — The Deduction That Doesn’t Work at State Level
Contributing to a traditional 401k reduces your federal taxable income — but Illinois does not follow federal treatment for 401k deductions. Illinois taxes your gross income before the 401k contribution is subtracted.
Example at $80,000 salary with 6% 401k ($4,800/year):
- Federal taxable income: $75,200 → saves ~$1,056 in federal tax
- Illinois taxable income: still $80,000 → no Illinois tax saving
Every dollar you contribute saves federal tax but not Illinois state tax. This is why your Illinois take-home drops by the full after-federal-tax
cost of the contribution — not the reduced amount you’d expect if both taxes were offset.

Illinois After-Tax Salary — Effective Tax Rate
Because Illinois uses a flat rate with no progression, the effective state tax rate is very close to 4.95% at all income levels (slightly lower due to the $2,925 exemption). At $65,000:
- Federal effective rate: ~9.0%
- Illinois effective rate: ~4.7%
- FICA effective rate: ~7.65%
- Total effective rate: ~21.4%
- Take-home percentage: ~78.6%
Frequently Asked Questions
What is the Illinois income tax rate for 2026?
Illinois uses a flat income tax rate of 4.95% on all taxable income for individuals. This rate applies to every dollar of income above the $2,925 personal exemption, regardless of how much you earn. The flat rate is constitutionally mandated and cannot be made progressive without a constitutional amendment, which Illinois voters rejected in 2020.
Does Chicago have a city income tax?
No. Chicago does not levy a local personal income tax. Illinois residents and workers in Chicago, Springfield, Rockford, or any other Illinois city pay only the state 4.95% flat tax — no additional municipal income tax. This distinguishes Illinois from states like Ohio (where cities charge up to 3%), Pennsylvania (Philadelphia charges 3.75%), and New York (NYC charges up to 3.876%).
How much is taken out of a paycheck in Illinois?
For a typical Illinois employee earning $65,000 as a single filer: approximately $6,820 federal income tax, $3,073 Illinois state tax, and $4,973 FICA (Social Security + Medicare) — totalling about $14,866 in annual deductions, leaving approximately $50,134 take-home. That’s roughly 21–22% of gross salary in total deductions. Use the calculator above for your specific salary and filing status.
Is Social Security taxed in Illinois?
No. Illinois does not tax Social Security benefits. Illinois also exempts 401(k) distributions, IRA withdrawals, pension income, and annuity payments from retirement accounts from state income tax entirely. This exemption applies to all Illinois residents receiving retirement income — making Illinois one of the most tax-friendly states for retirees, despite its high property taxes.
How does Illinois tax compare to neighboring states?
Indiana taxes income at 3.15% (flat), Michigan at 4.25% (flat), and Wisconsin at 3.5–7.65% (progressive). For most income levels, Illinois workers pay more state tax than Indiana and Michigan workers, and roughly similar to or less than Wisconsin workers at higher income levels. Missouri and Iowa are progressive and vary by income level. Illinois’s flat 4.95% is a midpoint among its neighbors.
Do Illinois residents who work in another state pay Illinois tax?
Yes, Illinois residents are taxed on all income regardless of where it’s earned. However, Illinois provides a credit for taxes paid to other states — so you generally don’t pay double. If you work in a reciprocal state (Wisconsin, Michigan, Iowa, Kentucky), you pay only your home state’s tax and file exemption paperwork with your employer.
What is the Illinois personal exemption for 2026?
The Illinois personal exemption is $2,925 for tax year 2026. This amount is subtracted from your gross income before the 4.95% state rate is applied, slightly reducing your effective state tax rate below 4.95% at all income levels.
How do pre-tax deductions affect my Illinois take-home?
Traditional 401(k) contributions and HSA contributions reduce your federal taxable income before federal tax is calculated. However, Illinois does not conform to all federal pre-tax treatment — specifically, Illinois taxes some employer-provided benefits differently.
