📊 Example Calculation
Let’s say you earn $20/hour, work 40 hours/week, and work 50 weeks/year.
- Gross Weekly Pay = $20 × 40 = $800.00
- Gross Annual Pay = $800 × 50 = $40,000.00
- Illinois State Tax (4.95%) = $40,000 × 0.0495 = $1,980.00
- After-Tax Annual Pay = $40,000 − $1,980 = $38,020.00
Result: You would take home about $38,020 per year after Illinois state tax (excluding federal taxes or other deductions).
