The rules in detail
- 1.5× the regular rate after 40 hours in a workweek (state law)
The Illinois Minimum Wage Law requires overtime after 40 hours in a workweek, independent of federal coverage.
Enforcement: Illinois Department of Labor.
Worked example
A Chicago delivery driver at $21/hour with a 50-hour week earns 10 × $31.50 = $315 overtime.
What Illinois employers sometimes get wrong
Illinois also enforces the One Day Rest In Seven Act (separate scheduling law) and sets its own, higher exempt-salary thresholds than the FLSA.
Who is entitled to overtime
Overtime rules protect “non-exempt” employees. The main federal exemptions cover executives, administrators, professionals, outside salespeople and certain computer employees — provided their duties genuinely match the exemption and they clear the salary basis test. Job titles mean nothing: an “assistant manager” who mostly runs a register is still non-exempt in the eyes of the law.
In practice, most hourly workers in Illinois are non-exempt and must receive overtime whenever the rules above trigger. Independent contractors are not covered — but misclassifying an employee as a contractor is one of the most common wage violations.
How to file an overtime claim in Illinois
Check your pay stubs and hours against the calculator above first. If you believe you were shorted, you can file a wage claim with Illinois Department of Labor or a complaint with the U.S. Department of Labor’s Wage and Hour Division (dol.gov/agencies/whd). The FLSA lets you recover unpaid overtime going back two years (three for willful violations), often doubled as liquidated damages.

As of the U.S. Department of Labor's November 5, 2026 table, Illinois's basic minimum rate is $15.00 per hour. The rate may adjust annually and can vary by city or county — check the state labor office for your exact locality.
How is overtime calculated in Illinois?
Multiply your regular hourly rate by 1.5 for every overtime hour. For example, at $20/hour a 45-hour week pays 40 × $20 + 5 × $30 = $950.
Do salaried employees get overtime?
Sometimes. A salary alone does not remove overtime rights — the employee must also perform exempt duties and (for the federal white-collar exemptions) clear the salary threshold. If the exemption tests fail, the employee is owed overtime regardless of pay format.
Does Illinois require overtime on weekends or holidays?
Federal FLSA rules do not require premium pay for weekends or holidays unless total weekly hours exceed the overtime threshold. Some state or employer policies may be more generous.
