Understanding your real take-home pay is essential for budgeting, saving, and financial planning. If you live or work in Illinois, knowing how much of your salary goes toward federal taxes, Illinois state tax, Social Security, and Medicare can help you make smarter financial decisions.

Our Illinois Net Income Calculator is a powerful and easy-to-use tool that estimates your net income after all major deductions. Whether you are paid weekly, bi-weekly, semi-monthly, monthly, or annually, this calculator gives you a clear breakdown of your paycheck.

In this detailed guide, you’ll learn how the calculator works, how to use it properly, see a practical example, and understand the tax components affecting your income.

What Is Net Income?

Net income (also called take-home pay) is the amount you receive after all required taxes and deductions are subtracted from your gross income.

Gross Income vs Net Income

  • Gross Income: Your total earnings before deductions.
  • Net Income: What you actually receive after:
    • Federal Income Tax
    • Illinois State Income Tax
    • Social Security
    • Medicare
    • Pre-tax deductions (401k, HSA, etc.)

Your paycheck may look large on paper, but deductions significantly reduce the final amount deposited into your bank account.

What Does the Illinois Net Income Calculator Include?

This tool calculates:

  • ✔ Federal Income Tax (based on filing status and tax brackets)
  • ✔ Illinois State Income Tax (flat 4.95%)
  • ✔ Social Security Tax (6.2% up to annual wage cap)
  • ✔ Medicare Tax (1.45% + additional 0.9% for high earners)
  • ✔ Standard Deduction (based on filing status)
  • ✔ Pre-tax deductions (401k, HSA, etc.)
  • ✔ Per-pay-period breakdown

This gives you a realistic and accurate estimate of your Illinois take-home pay.

How to Use the Illinois Net Income Calculator

Using the calculator is simple. Follow these steps:

Step 1: Enter Gross Annual Income

Input your total yearly salary before taxes.

Example:
If you earn $65,000 per year, enter 65000.

Step 2: Select Pay Period

Choose how often you are paid:

  • Weekly (52)
  • Bi-Weekly (26)
  • Semi-Monthly (24)
  • Monthly (12)
  • Annual (1)

The calculator divides your yearly income accordingly.

Step 3: Select Filing Status

Choose your tax filing status:

  • Single
  • Married Filing Jointly
  • Head of Household

This affects:

  • Standard deduction amount
  • Federal tax brackets

Step 4: Enter Number of Dependents

Input how many dependents you claim. While dependents don’t directly reduce tax in this simplified model, they are part of financial planning.

Step 5: Enter Pre-Tax Deductions

Add annual contributions such as:

  • 401(k)
  • Health Savings Account (HSA)
  • Retirement plans

These reduce taxable income before taxes are calculated.

Step 6: Click “Calculate”

You’ll instantly see:

  • Gross Income (per selected pay period)
  • Federal Tax
  • Illinois State Tax
  • Social Security
  • Medicare
  • Final Net Income

Real Example Calculation

Let’s walk through a practical example.

Scenario:

  • Gross Income: $75,000
  • Filing Status: Single
  • Pay Period: Bi-Weekly
  • Pre-Tax Deductions: $5,000
  • Dependents: 0

Step-by-Step Breakdown:

  1. Taxable Income = $75,000 – $5,000 = $70,000
  2. Standard Deduction (Single) = $13,850
  3. Adjusted Taxable Income = $56,150

From here:

  • Federal tax is calculated using progressive brackets.
  • Illinois state tax = 4.95% of taxable income.
  • Social Security = 6.2% (up to wage limit).
  • Medicare = 1.45%.

After all deductions, your estimated bi-weekly take-home pay is displayed.

This helps you know exactly what you’ll receive every two weeks.

Understanding Illinois State Income Tax

Illinois uses a flat income tax rate of 4.95%. Unlike some states, Illinois does not use progressive tax brackets at the state level.

This makes state tax calculation simpler compared to federal income tax.

Federal Tax Brackets Explained

Federal income tax uses a progressive system, meaning:

  • Lower income portions are taxed at lower rates.
  • Higher income portions are taxed at higher rates.

Your entire income is not taxed at the highest bracket — only the portion that falls into each bracket.

This calculator automatically applies the correct bracket based on your filing status.

Social Security and Medicare (FICA Taxes)

Social Security

  • 6.2% of income
  • Wage cap applies (maximum taxable income limit)

Medicare

  • 1.45% standard rate
  • Additional 0.9% for income over $200,000

These are mandatory payroll taxes deducted from your paycheck.
