What changes your Illinois take-home pay the most

Your Form W-4 withholding settings can make a paycheck look higher or lower than a plain tax-liability estimate.
Health insurance, retirement contributions, HSA contributions, commuter benefits, and other payroll deductions reduce take-home pay.
Bonuses, overtime, RSUs, and supplemental wages may use a different withholding method than base salary.
State and local rules can differ from a simplified effective-rate model, especially in places with city taxes or multiple brackets.

In practice, the biggest gaps usually come from pre-tax benefits, filing status, and state or local withholding. That is why the editable calculator matters more than the default number alone.
