Understanding Overtime Pay Rates in Illinois
Illinois overtime laws require non-exempt employees to receive 1.5 times their regular hourly rate for all hours worked beyond 40 in a single workweek. This calculation is based on a fixed, regularly recurring period of 168 consecutive hours, defined as a workweek. Unlike some states, Illinois does not require overtime pay for working more than 8 hours in a single day. This means that an employee's overtime earnings are solely dependent on exceeding 40 hours in a week.
The "regular rate of pay"—which serves as the baseline for overtime calculations—includes all forms of compensation such as hourly wages, salaries, commissions, and non-discretionary bonuses. For salaried employees eligible for overtime, their regular hourly rate is calculated by dividing their weekly salary by 40, and then multiplying that rate by 1.5 for overtime hours. These regulations ensure a fair compensation structure that complies with the Illinois Minimum Wage Law (IMWL), 820 ILCS 105/4a.
