How the Illinois paycheck calculator works
This calculator estimates your take-home pay by applying four layers of US payroll taxes to your gross annual salary: federal income tax, Illinois state income tax, Social Security (6.2%), and Medicare (1.45%). High earners pay an additional 0.9% Medicare surtax above the IRS threshold.
Federal income tax
Federal tax uses progressive brackets ranging from 10% to 37%. Each dollar is taxed only at the rate of the bracket it falls into — this is called your marginal rate, not your effective rate. The calculator applies the 2025 IRS brackets (Rev. Proc. 2024-40) and the $15,000 standard deduction for single filers.
Illinois state income tax
Illinois uses progressive state tax brackets sourced from Illinois Department of Revenue (tax.illinois.gov), 2025 tax year. The state standard deduction is automatically applied based on your filing status. Illinois taxes income at a flat 4.95% after a personal exemption allowance (about $2,850 per person for 2025). This estimate models the taxpayer's own exemption and does not add exemptions for dependents.
FICA (Social Security + Medicare)
FICA taxes are flat: 6.2% Social Security on wages up to the 2025 cap of $176,100, plus 1.45% Medicare on all wages. Single filers earning over $200,000 pay an additional 0.9% Medicare surtax on income above that threshold.
