Illinois Overtime Laws 2026
Under the Illinois Minimum Wage Law (IMWL), employers must pay overtime at a rate of 1.5 times the regular hourly rate for hours worked over 40 in a workweek.
Key IL Rules:
- 40-Hour Rule: Strict weekly overtime requirement for non-exempt employees.
- Minimum Wage: Illinois has a progressively increasing minimum wage, reaching $15.00 by 2025. Ensure your inputs reflect current rates.
Calculation Example:
If you work 50 hours in Chicago at $18/hr:
- Regular Pay: 40 hours × $18 = $720.00
- Overtime Rate: $18 × 1.5 = $27.00/hr
- Overtime Pay: 10 hours × $27 = $270.00
- Total Pay: $720 + $270 = $990.00
