Why Your Net Pay Is Different Each Time
Several factors determine how much money actually lands in your bank account:
1. Federal Tax
Federal withholding depends on your W-4 information and filing status (Single, Married, etc). This is usually the largest deduction.
2. FICA Taxes
Social Security (6.2%) and Medicare (1.45%) are fixed percentage taxes taken from almost every paycheck nationwide.
3. Illinois Flat Tax
Illinois uses a flat state income tax rate of 4.95% on taxable income. This makes predicting your state tax liability easier.
Illinois Paycheck FAQ
What taxes are taken out of my Illinois paycheck?
Your paycheck will show deductions for Federal income tax, Social Security (6.2%), Medicare (1.45%), and the Illinois flat state income tax (4.95%).
Does Illinois have local income tax?
Typically, no. Most cities and counties in Illinois do not impose a separate local personal income tax, unlike some other states.
Can this calculator handle overtime?
Yes. Simply enter your total overtime hours. We calculate overtime pay at 1.5× your standard hourly rate.
Why doesn’t this match my actual paycheck exactly?
Small differences may occur due to specific employer payroll software rounding rules, exact pay periods, or pre-tax benefit specifics.
What is IL-W-4?
The IL-W-4 is the Illinois Employee’s Withholding Allowance Certificate. It determines how many allowances you claim, which affects how much state tax is withheld.
