Where your Illinois paycheck goes
Quick insights about your Illinois paycheck
Your effective tax rates
Effective rates are total annual tax divided by gross annual pay. Marginal rates show the tax rate on your next dollar of income based on the brackets this calculator uses.
How we estimate your 2026 Illinois take home pay
The calculator follows a clear step by step process based on 2026 federal payroll rules and Illinois income tax rules for regular W-2 wages.
-
1Start with your gross pay
For salary, we use your annual salary divided by your selected pay frequency. For hourly workers, we multiply your hourly rate by your average weekly hours and then convert that to the pay period you picked. If needed, you can double check income using the salary calculator or salary to hourly calculator.
-
2Subtract your pre-tax deductions
We subtract any pre-tax 401(k), health, FSA, HSA, or other pre-tax amounts per paycheck you enter. This lowers the income that federal and Illinois income taxes apply to, which can improve your net pay and effective tax rate.
-
3Apply federal and Illinois income tax rules
On this lower taxable income, we estimate 2026 federal income tax using the federal tax brackets and your filing status. We also apply the Illinois flat income tax rate for 2026 on taxable wages, then add any extra per paycheck federal or Illinois withholding you enter.
-
4Calculate Social Security and Medicare
We apply standard 2026 FICA rates for Social Security and Medicare on covered wages, including the Social Security wage base cap where required. If your income is high enough for additional Medicare tax, we note that in the insights area.
-
5Subtract post-tax deductions to reach net pay
Finally, we subtract any post-tax deductions and Roth amounts per paycheck you enter. The result is your estimated net Illinois paycheck and an annual take home pay number you can use alongside tools like the US paycheck calculator or net to gross calculator.
Important Illinois paycheck points for 2026
These notes explain how typical Illinois paychecks are taxed in 2026 and how to use this calculator alongside other USAJobsKit tools.
Illinois flat income tax vs federal brackets
Illinois uses a flat state income tax rate that applies to most taxable wages. Federal income tax uses a progressive bracket system where higher portions of your income are taxed at higher marginal rates. This calculator splits your paycheck into federal, Illinois, and FICA lines so you can see which part has the biggest impact on your net pay.
Impact of pre-tax benefits on Illinois take home pay
Pre-tax benefits can reduce the amount of income subject to both federal and Illinois income tax. Contributing to a 401(k), FSA, or HSA often lowers your taxable wages, which this calculator reflects. To explore different benefit scenarios, you can also run numbers with the pre-tax deduction calculator or payroll tax calculator.
Comparing Illinois paychecks to other states
If you might move or work remotely, compare your estimated Illinois paycheck with other state tools like the California paycheck calculator, Texas paycheck calculator, or Florida paycheck calculator. This helps you understand how Illinois taxes and benefits stack up for your income level.
