How This Illinois Salary Calculator Works

This Illinois salary calculator estimates your take-home pay by subtracting three categories of taxes from your gross income:

  1. Federal income tax using 2025 brackets (10% to 37%)
  2. Illinois state income tax (flat 4.95%)
  3. FICA -- Social Security (6.2% up to $176,100) and Medicare (1.45%)

The result is an estimate for a single filer with no pre-tax deductions. It does not include local taxes, 401(k) contributions, health insurance premiums, or other withholdings. For exact paycheck amounts, consult your employer or a tax professional.
