Practical Example
Scenario:
You earn $4,000 per month in Illinois. Your federal tax rate is 12%, and the state tax rate is 4.95%.
Calculation:
- Federal Tax Amount: $4,000 × (12 ÷ 100) = $480.00
- Illinois State Tax Amount: $4,000 × (4.95 ÷ 100) = $198.00
- Net Pay: $4,000 − $480 − $198 = $3,322.00
So, your estimated take-home pay would be $3,322.00 per month.
