If you run an hourly crew in Illinois, two questions come up every payroll: how much do you owe once someone crosses into overtime, and are you following the state's rules. Illinois uses the federal 40-hour rule, so any hour past 40 in a workweek is paid at 1.5 times the regular rate. The Illinois minimum wage is $15.00 an hour. This page gives you a free Illinois overtime calculator, a plain summary of the state's wage and hour rules, and a look at how Clox tracks your crew's hours.

Illinois wage and hour rules
Here's the short version of the rules an hourly Illinois employer runs into. Each figure has a source below, and the rules change over time, so confirm anything you rely on with the state.
$15.00 per hour statewide since January 1, 2025 for workers 18 and older. This is the final step of the 2019 schedule signed by Governor Pritzker, and no further state increases are scheduled without new legislation. Tipped employees may be paid a cash wage of $9.00 per hour when tips bring total pay to at least $15.00 (the tip credit is capped at 40 percent of the minimum wage). Workers under 18 who work fewer than 650 hours in a calendar year may be paid $13.00 per hour. Employers may also pay a training wage of $14.50 for the first 90 days for new workers 18 and older. Local minimums are higher in Chicago and Cook County (see asOfNote).
1.5x the regular rate after 40 hours in a workweek. Illinois follows the federal FLSA weekly standard, and the Illinois Minimum Wage Law is enforced by the Illinois Department of Labor.
None. Illinois has no daily overtime and no double-time requirement. Overtime is weekly only, owed on hours worked over 40 in a workweek. Working long single-day shifts, holidays, or Sundays does not by itself trigger overtime.
Under the One Day Rest In Seven Act (ODRISA), employees must receive a meal period of at least 20 minutes for every 7.5-hour shift, beginning no later than 5 hours after the start of the shift, with an additional 20-minute meal period for every additional 4.5 continuous hours worked. ODRISA also guarantees at least 24 consecutive hours of rest in every 7 consecutive days.
Employers must provide reasonable restroom breaks, but Illinois does not mandate a separate paid 10 to 15 minute rest break.
This applies whether the employee quits or is discharged.

Track Illinois hours accurately with Clox
A calculator is only as accurate as the hours you put into it. Clox is time tracking built for field and trade crews, so your crew's hours are recorded accurately in the first place, then the overtime is figured for you.
- Your crew clocks in with one tap on their phone, and it works offline, so a dead zone on the job doesn't lose a punch.
- Lock clock-in to a geofenced worksite so a punch has to happen on site. It's a strong deterrent, not a foolproof guarantee, because the location comes from the phone.
- Overtime is calculated automatically on the Illinois weekly-40 rule, so you're not doing this math by hand every Friday.
- Export payroll-ready files for QuickBooks, Gusto, ADP, and Paychex when the week is done.
If your crew moves between addresses during the day, settle how you handle drive time between job sites before you run the numbers. Those hours can count toward the weekly total, and leaving them untracked understates the overtime you owe.
