How the math works
We start with gross salary, subtract federal income tax (2026 brackets after the $16,100/$32,200 standard deduction per IRS Rev. Proc. 2025-32), Social Security (6.2% on wages up to the $184,500 2026 wage base), Medicare (1.45%, plus 0.9% above $200,000), and Illinois state income tax using the 2026 brackets shown above. Enter a 401(k) percentage and it comes off your income-taxable wages but still pays Social Security and Medicare, exactly as payroll handles it; HSA, FSA and health premiums taken through an employer cafeteria plan come off both. Local city taxes and state payroll programs are not included, so treat results as close estimates.
