How This Calculator Works
Calculation methodology and assumptions
This calculator computes take-home pay on a $40,000 salary in Illinois. Federal tax uses 2026 brackets with a standard deduction of $16,100. Illinois has a flat 4.95% state income tax. This estimate applies each state's tax rate(s) to your full gross salary; it does not subtract a state-specific standard deduction or personal exemption credit (state tax code differs too much state-to-state to model precisely here), so your actual state tax bill is likely somewhat lower than shown. FICA includes Social Security (6.2% up to $184,500) and Medicare (1.45% + 0.9% additional above $200,000).
