How Does an Illinois Paycheck Calculator Work?

A paycheck calculator estimates your net income by considering several factors. Here’s how it works:

Step 1: Enter Your Gross Salary

The calculator will first ask for your annual salary or hourly wage. This is the amount you earn before any deductions are made.

Step 2: Select Your Filing Status

Your filing status (e.g., single, married, or head of household) plays a crucial role in determining your federal tax rate. Illinois also uses this information to apply the correct state tax rate.

Step 3: Add Pre-tax and Other Deductions

Next, the calculator asks for details about any pre-tax deductions (like 401(k) contributions) and other deductions (such as health insurance premiums). These deductions reduce your taxable income, lowering the taxes you owe.

Step 4: View the Results

After entering all the information, the calculator provides a detailed breakdown of your taxes:

• Federal tax
• Illinois state tax (4.95%)
• Social Security (6.2%)
• Medicare (1.45%)
  It also shows your final net pay — the amount you take home after taxes and deductions.
