Living & Working in Illinois — Tax & Pay Guide 2025

Illinois takes a simpler approach to state income taxes than most states: a flat 4.95% rate on all taxable income, applied after the state standard deduction of $0 for single filers. There are no brackets — whether you earn $30,000 or $300,000, the same percentage applies to your taxable income. That predictability makes it easy to plan your take-home.

Compared to progressive states, Illinois's flat tax is particularly favorable for higher earners. At $150,000, a high-tax progressive state might apply 8–13% to income above certain thresholds, while Illinois stays at 4.95% throughout. For middle-income earners, the difference is smaller but still meaningful.

Workers in Chicago and Aurora should note that your actual take-home also depends on federal income tax brackets (which are the same for everyone in every state), FICA payroll taxes (6.2% Social Security + 1.45% Medicare), and any pre-tax deductions like 401(k) contributions. The calculator above models all of these together.

For 2025, Illinois's flat 4.95% rate puts it in the middle of the national range — better than states like California, Hawaii, or New Jersey, but trailing the 9 states with no income tax at all.

How Take-Home Pay Is Calculated in Illinois

Your Illinois net pay = Gross Salary − Federal Tax − State Tax − FICA − Pre-Tax Deductions.

Gross = Hourly Rate × Hours × Weeks OR stated annual salary

Example:

Example: $75,000 annual salary

$75,000
= $75,000 gross

Federal Tax = Apply 2025 brackets to (Gross − Standard Deduction − Pre-Tax Deductions)

Example:

$75,000 single filer

~$8,054 federal tax
= ~10.7% effective

Variables:

10% - $0 – $11,925
12% - $11,925 – $48,475
22% - $48,475 – $103,350
24% - $103,350 – $197,300

State Tax = (Gross − $0 std. deduction) × 4.95%

Example:

$75,000 in Illinois

Use calculator above for exact amount
= Varies

Variables:

Std. Deduction - $0 single / $0 MFJ

FICA = (Social Security: 6.2% up to $176,100) + (Medicare: 1.45%)

Example:

$75,000

$4,650 SS + $1,088 Medicare
= $5,738 FICA

Variables:

SS Rate - 6.2% up to $176,100
Medicare - 1.45% all wages (+0.9% above $200K)

These formulas provide the mathematical foundation for the calculations. Actual results may vary based on rounding, compounding frequency, and specific lender policies.

Illinois Take-Home Pay — FAQs

Common questions about take-home pay, taxes, and salary comparison in Illinois.

How much take-home pay do you get in Illinois on a $75,000 salary?

At $75,000 gross, a single filer in Illinois typically takes home approximately $58,000–61,000 annually after federal tax, state income tax, and FICA. Use the calculator above for your exact number based on filing status and deductions.

What is FICA and does it apply in every state?

FICA stands for Federal Insurance Contributions Act — it covers Social Security (6.2% up to $176,100) and Medicare (1.45% on all wages). FICA is the same in every state; it's a federal payroll tax and doesn't vary by location.

Does moving to a no-tax state really save money?

It can — significantly. On a $100,000 salary, moving from California (9.3% top marginal) to a no-tax state like Texas or Florida could save $6,000–$9,000 per year in state income tax alone. However, no-tax states often offset this with higher property taxes or sales taxes. Use this calculator to compare net pay, but factor in total cost of living too.

What pre-tax deductions reduce my taxable income in Illinois?

401(k) contributions (up to $23,500 in 2025), HSA contributions ($4,300 individual / $8,550 family), and employer-sponsored health insurance premiums are all pre-tax deductions that reduce both federal and most state taxable income. The calculator above lets you model these.
