Illinois regulates wages heavily, and through several statutes rather than one. The Minimum Wage Law sets a $15.00 floor and the overtime rule; the Wage Payment and Collection Act governs how often and how quickly workers must be paid, what a pay stub must show, when final wages are due, and how a shortfall is penalized; and the One Day Rest in Seven Act mandates meal periods and a weekly day of rest. What Illinois does not add, it leaves to the federal Fair Labor Standards Act — there is no daily-overtime tier and no general paid-rest-break rule. Two features make Illinois exposure unusually sharp: aggressive, compounding penalties for underpayment, and a layer of higher local minimum wages in Chicago and suburban Cook County. This note walks through each rule an in-house team has to get right for an Illinois workforce. For the cross-state framework, see the wage and hour practice guide.
What is the minimum wage?
Illinois has a single statewide minimum wage of $15.00 per hour for workers 18 and older, well above the federal floor of $7.25. The rate reached $15.00 on January 1, 2025, the top of a fixed dollar-a-year schedule the General Assembly wrote into the Minimum Wage Law in 2019; the statute has no CPI escalator, so absent new legislation the state floor stays at $15.00 . Two narrower rates sit in the same section: a worker under 18 who has not worked more than 650 hours in the calendar year may be paid $13.00, and during a new hire's first 90 calendar days an employer may pay up to 50 cents less than the standard rate. Local minimums run higher — the City of Chicago and suburban Cook County both set their own floors that exceed the state rate and adjust every July 1 — so an employer must check the rate for each work location, not just the state figure.
Because the increases were fixed by statute rather than indexed, the climb ended at $15.00 and does not move with inflation. Section 4 lays out the full schedule, from the historical rates up to the current floor.
The $15.00 figure is only the state floor. Chicago and suburban Cook County impose higher local minimum wages that step up every July 1, so payroll for an Illinois workforce has to be set by work location — the state rate alone can underpay a Chicago or suburban Cook County employee .

A.1 820 ILCS 105/4Section 4(a)(1) of the Illinois Minimum Wage Law sets the statewide minimum wage on a fixed legislative schedule that reaches $15.00 per hour for employees 18 and older on and after January 1, 2025, with no CPI indexing built into the text.
on and after January 1, 2025, every employer shall pay to each of his or her employees who is 18 years of age or older in every occupation wages of not less than $15 per hour.
See 820 ILCS 105/4(a)(1).
When is overtime owed?
Overtime in Illinois is a weekly rule, not a daily one. Section 4a of the Minimum Wage Law requires one-and-one-half times the regular rate for hours worked over 40 in a workweek, and there is no state daily-overtime or double-time tier the way California has . The threshold and multiplier track the federal Fair Labor Standards Act, so for most employers the practical overtime question is simply whether weekly hours crossed 40. The Illinois statute carries its own list of exemptions — for example bona fide executive, administrative, and professional employees, and certain commissioned and agricultural workers — largely mirroring the federal exemptions.
The operative rule is short and weekly. Section 4a fixes the 40-hour trigger and the time-and-a-half rate.
Because Illinois adds no daily-overtime layer, an employee who works four ten-hour days earns no overtime under state law, while an employee who works six seven-hour days does — the analysis turns on the weekly total, not the length of any single shift.

B.1 820 ILCS 105/4aSection 4a(1) of the Illinois Minimum Wage Law requires overtime at one-and-one-half times the regular rate for hours over 40 in a workweek and imposes no daily-overtime or double-time tier, so Illinois overtime is a weekly-only standard.
Except as otherwise provided in this Section, no employer shall employ any of his employees for a workweek of more than 40 hours unless such employee receives compensation for his employment in excess of the hours above specified at a rate not less than 1 1/2 times the regular rate at which he is employed.
See 820 ILCS 105/4a(1).
Are breaks required?
Yes for meal periods, mostly no for rest breaks. The One Day Rest in Seven Act requires a 20-minute meal period for an employee scheduled to work 7.5 continuous hours, beginning no later than five hours into the shift, plus an additional 20-minute meal period for every further 4.5 continuous hours worked . The same Act guarantees at least 24 consecutive hours of rest in every consecutive seven-day period . Illinois does not require general paid rest breaks for most workers; whether a short break an employer chooses to offer counts as paid time is a question of federal Fair Labor Standards Act law, not a state entitlement. One occupation is treated more generously: a hotel room attendant in a county over three million people (Cook County) is entitled to two paid 15-minute rest breaks and a 30-minute meal period on any workday of at least seven hours , and an employer that fails to provide those breaks owes three times the attendant's regular hourly rate for each affected workday . For the general day-of-rest and meal-period rules, a missed period carries Department penalties and employee damages rather than a California-style premium .
The core meal-period rule keys off a 7.5-hour continuous shift and a five-hour deadline.
Separately, the Act's weekly rule guarantees a full day off in each seven-day period.
Enforcement is by civil penalty and employee damages, scaled to employer size, with each missed meal period counting as a separate offense.

When is final pay due?
Final compensation is due at the time of separation if possible, and in no case later than the next regularly scheduled payday — the same deadline whether the worker quit or was fired . Final compensation is defined broadly to include wages, salary, earned commissions, earned bonuses, and the monetary equivalent of earned vacation. Illinois also bars use-it-or-lose-it forfeiture: any earned but unused vacation must be cashed out at the final rate of pay, and no policy may make it forfeit on separation . Paying late is expensive — the Wage Payment and Collection Act adds compounding penalties, covered in the next question.
The timing rule is uniform and payday-based; separation does not accelerate the clock past the next regular payday.
Earned vacation is a protected liability. An employer may cap accrual, but banked vacation must be paid out and cannot be written off at separation.

See 820 ILCS 115/5.
What is the penalty for paying late?
Illinois runs a compounding late-pay penalty. Under the Wage Payment and Collection Act, an employee who is not paid wages, final compensation, or wage supplements on time recovers the underpayment plus damages of 5% of the amount owed for each month it stays unpaid — and in a civil action, costs and all reasonable attorney's fees . The clock keeps running until the debt is paid, so a modest final-pay dispute can grow month over month. The pressure ratchets further once the state gets involved: an employer that ignores a Department demand or a court order and fails to comply within 15 days of the demand (or 35 days of an order) owes an additional 20% penalty to the Department plus 1% of the amount owed to the employee for each day of delay .
The base remedy is the per-month damages figure, which accrues automatically on any late payment.
Ignoring a demand or order compounds the exposure with a fixed penalty and a daily add-on.
The 5%-a-month damages accrue for each month a wage or final-pay underpayment stays unpaid, so a disputed final paycheck or a mis-valued vacation payout can generate damages that outgrow the amount originally owed — pay the undisputed portion promptly rather than letting the clock run .

Any employee not timely paid wages, final compensation, or wage supplements by his or her employer as required by this Act shall be entitled to recover through a claim filed with the Department of Labor or in a civil action, but not both, the amount of any such underpayments and damages of 5% of the amount of any such underpayments for each month following the date of payment during which such underpayments remain unpaid.

Any employer who has been so demanded or ordered by the Department or ordered by a court to pay such wages, final compensation, or wage supplements and who fails to seek timely review of such a demand or order as provided for under this Act and who fails to comply within 15 calendar days after such demand or within 35 days of an administrative or court order is entered shall also be liable to pay a penalty to the Department of Labor of 20% of the amount found owing and a penalty to the employee of 1% per calendar day of the amount found owing for each day of delay in paying such wages to the employee.
See 820 ILCS 115/14(b).
How often must workers be paid?
At least semi-monthly. The Wage Payment and Collection Act requires every employer to pay all wages earned during the semi-monthly pay period at least twice a month, though executive, administrative, and professional employees and commissions may be paid monthly . There is also a lag limit: wages earned in a semi-monthly or bi-weekly period must be paid within 13 days after the end of that period . Illinois pairs the cadence rule with a detailed wage-statement rule — since January 1, 2025 an employer must furnish each employee a pay stub for every pay period , and the statutory definition of a pay stub fixes what it must show: hours worked, rate of pay, overtime pay and overtime hours, gross wages, itemized deductions, and year-to-date totals .
The cadence floor is semi-monthly, with a monthly option only for exempt staff and commissions.
The pay stub is not optional and its contents are defined by statute, so a bare net-pay slip does not comply.

Employee or independent contractor?
Illinois classifies wage-payment workers with a strict statutory ABC-style test, not a general balancing test. For coverage under the Wage Payment and Collection Act — unpaid wages, unauthorized deductions, or final pay — a worker is treated as an employee unless the hiring party proves all three prongs of a conjunctive exclusion: the worker is free from control, performs work outside the usual course or places of business, and is engaged in an independently established trade or business . Because the test is conjunctive, failing any one prong defaults the worker to employee status for the Act's protections. A separate statute, the Employee Classification Act, imposes an even stricter presumption of employee status — but it reaches only the construction industry, so it is a sector-specific overlay, not the general Illinois wage-hour classification rule .
Under the Wage Payment and Collection Act, contractor status must be affirmatively proven on all three prongs.
Construction is harder still: the Employee Classification Act treats anyone performing services for a contractor as an employee unless the contractor clears a parallel three-prong test or proves a legitimate subcontractor relationship.
Do not assume a single classification answer across Illinois statutes: the wage-payment ABC test is conjunctive and hard to satisfy, so a worker can be an independent contractor for a tax or federal purpose yet an employee for unpaid-wage and final-pay exposure under the Wage Payment and Collection Act .

As used in this Act, the term “employee” shall include any individual permitted to work by an employer in an occupation, but shall not include any individual: (1) who has been and will continue to be free from control and direction over the performance of his work, both under his contract of service with his employer and in fact; and (2) who performs work which is either outside the usual course of business or is performed outside all of the places of business of the employer unless the employer is in the business of contracting with third parties for the placement of employees; and (3) who is in an independently established trade, occupation, profession or business.

An individual performing services for a contractor is deemed to be an employee of the contractor unless it is shown that: (1) the individual has been and will continue to be free from control or direction over the performance of the service for the contractor, both under the individual's contract of service and in fact; (2) the service performed by the individual is outside the usual course of services performed by the contractor; and (3) the individual is engaged in an independently established trade, occupation, profession or business; or (4) the individual is deemed a legitimate sole proprietor or partnership under subsection (c) of this Section.

Is a tip credit allowed?
Yes, a partial one. The Minimum Wage Law lets an employer in a tipped occupation credit gratuities toward the minimum wage up to 40% of the applicable minimum wage rate . At the $15.00 state minimum, that caps the credit at $6.00 and sets a tipped cash-wage floor of $9.00 an hour — and the employer must be able to show the tips were actually received and not returned. Tips themselves belong to the worker: the Wage Payment and Collection Act makes gratuities the property of the employee and bars the employer from keeping them, though it permits lawful tip pooling and a proportionate deduction of credit-card processing fees . Local rules diverge — Chicago has been phasing down its tip credit and suburban Cook County sets its own tipped minimum — so a tipped-worker cash wage has to be checked against the applicable local ordinance, not just the state cap.
The state credit is a percentage cap, not a frozen dollar figure, so it rises with the minimum wage.
The credit does not give the employer any claim on the tips; those are the employee's property by statute.

Every employer of an employee engaged in an occupation in which gratuities have customarily and usually constituted and have been recognized as part of the remuneration for hire purposes is entitled to an allowance for gratuities as part of the hourly wage rate provided in Section 4, subsection (a) in an amount not to exceed 40% of the applicable minimum wage rate.

How is it enforced?
By both the state and private suit, with heavy remedies. Under the Minimum Wage Law, an employee paid less than the required wage may sue for treble the underpayment plus costs, reasonable attorney's fees, and 5%-a-month damages, and the action must be brought within three years of the underpayment . Under the Wage Payment and Collection Act, an aggrieved employee may go straight to Illinois circuit court without exhausting administrative remedies, or file a wage-claim complaint with the Illinois Department of Labor within one year . The Department of Labor is the primary enforcing agency, with subpoena power and the ability to take assignments of wage claims. Illinois employees also keep the full federal Fair Labor Standards Act remedy — a private action for unpaid minimum wage or overtime — which often runs alongside the state claims.
The Minimum Wage Law's private action is the enhanced remedy: treble damages, fees, and the monthly damages, on a three-year clock.
The Wage Payment and Collection Act lets the employee choose court or agency, and does not require exhausting the agency route first.
