Illinois Overtime Rules
Illinois pays overtime on a weekly basis. Employees earn 1.5× their regular rate after 40 hours in a workweek. Illinois does not have daily overtime.
- 1.5× pay for hours worked beyond 40 in a workweek.
- No daily overtime: only weekly hours over 40 count toward overtime.
- Chicago and Cook County set a higher local minimum wage than the Illinois state rate.
Illinois also has a One Day Rest in Seven Act governing rest days and meal breaks, but that is separate from overtime. For pay calculations, only weekly hours over 40 matter.
The Illinois minimum wage is $15.00/hour (tipped minimum $9.00). Chicago: $16.20. Overtime is calculated on your actual hourly rate, not the minimum. See the full 2026 minimum wage table or compare states side by side.

Yes. Chicago and Cook County set their own minimum wages above the Illinois state rate, on their own schedule. Overtime is still 1.5× of your actual hourly rate — report unpaid overtime to the Illinois Department of Labor.
