How Illinois Income Tax Works
1. Illinois State Income Tax (4.95%)
Illinois uses a flat income tax rate of 4.95%. This means everyone pays the same percentage regardless of income level.
Formula:
State Tax = Taxable Income × 4.95%
Your taxable income is calculated after subtracting pre-tax deductions.
2. Federal Income Tax (Progressive System)
Unlike Illinois, federal income tax uses a progressive bracket system. The more you earn, the higher the percentage you pay on portions of your income.
The calculator estimates federal tax based on:
- Filing status (Single, Married Filing Jointly, Head of Household)
- Standard deduction
- Number of exemptions
- Current federal tax brackets
3. Social Security Tax (6.2%)
Social Security tax is 6.2% of your income up to a wage limit.
4. Medicare Tax (1.45%)
Medicare tax is 1.45% of your total income, with no income cap for most taxpayers.
