Illinois requires an employer to pay a departing worker’s final compensation no later than the next regularly scheduled payday after separation. The Illinois final paycheck law is part of the broader Illinois employment law framework set by the Illinois Wage Payment and Collection Act, which governs when, where, and how wages and final pay are paid. This article covers the deadline, what final compensation includes, how unused vacation is treated, and the options a worker has when a final paycheck arrives late.
When your final paycheck is due
Under 820 ILCS 115/5, an employer must pay the final compensation of separated employees in full at the time of separation, if possible, but in no case later than the next regularly scheduled payday for that employee. The deadline is tied to the employer’s normal pay cycle rather than a fixed number of days. If the next regular payday falls the day after separation, final pay is due then; if payday is two weeks out, that later date controls. The same standard is explained by Illinois Legal Aid Online in its guide on rights after being laid off or fired.
What counts as final compensation
The Act defines the term broadly. Under 820 ILCS 115/2, final compensation is “wages, salaries, earned commissions, earned bonuses, and the monetary equivalent of earned vacation and earned holidays, and any other compensation owed the employee by the employer” under an employment contract or agreement. A final paycheck is therefore more than the last stretch of hourly or salary wages. It also includes commissions and bonuses the worker already earned, plus the cash value of accrued, unused vacation.
Whether unused vacation must be paid out
When employment ends, 820 ILCS 115/2 requires payment of the monetary equivalent of earned, unused vacation at the worker’s final rate of pay, and it bars any employment contract or policy that provides for forfeiture of earned vacation on separation. Illinois does not permit “use it or lose it” policies that erase already-earned vacation, a point Illinois Legal Aid Online addresses in its explanation of getting paid for unused vacation when you leave a job. An employer may cap how much vacation accrues going forward, but time already earned converts to a payable amount at separation. The overlap between accrued leave and the final paycheck is covered in more depth in Illinois PTO payout at termination.
Quit, laid off, or fired: the deadline is the same
Illinois is an at-will state, which means either side can generally end the employment relationship at any time; the mechanics of that are explained in at-will employment in Illinois. The manner of separation does not change the final-pay deadline. The next-payday rule applies whether a worker resigns, is laid off, or is discharged, including a discharge the worker believes was improper. A dispute over the reason for a firing, such as a claim of wrongful termination in Illinois, is a separate matter from the employer’s statutory obligation to pay final compensation on time. ## What to do when final pay is late A worker whose final compensation is not paid by the deadline has two avenues under the Act: a wage claim with the Illinois Department of Labor, or a civil lawsuit, but not both for the same wages. A claim filed with the Department must be brought within one year after the wages or final compensation were due, as Illinois Legal Aid Online explains in how far back you can collect unpaid wages.
Gather your records
Collect pay stubs, the offer letter or employment agreement, timesheets, and any record of an accrued vacation balance. These documents establish the amount of final compensation owed and the date it became due.
Make the request in writing
A written request for the final paycheck creates a record of the demand. Under 820 ILCS 115/5, a worker who asks in writing to have the check mailed is entitled to have the employer mail it.
File a claim with the Illinois Department of Labor
The Department accepts wage claims through its Fair Labor Standards Division. A claim must be filed within one year of the date the final compensation was due. Illinois Legal Aid Online outlines the process in starting a case to get back unpaid wages.
Or pursue the claim in court
Illinois allows a worker to seek unpaid final compensation either through the Department of Labor or in court, but not both for the same wages. Smaller amounts can be pursued in small claims.
820 ILCS 115/14, the employer owes the unpaid amount plus damages of 5% of the underpayment for each month it remains unpaid. When payment is ordered by the Department of Labor, the employer also owes a non-waivable administrative fee, which starts at $500 when the wages owed are $3,000 or less and rises with the amount ordered. Willful refusal to pay can carry criminal liability, up to a Class A misdemeanor and, for larger or repeat violations, a felony.
Frequently asked questions
Does the final paycheck deadline change if I quit instead of getting fired?
No. Under 820 ILCS 115/5, final compensation is due at the time of separation if possible and no later than the next regularly scheduled payday, and that deadline applies whether the worker resigns, is laid off, or is discharged.
Can an employer hold my final paycheck until I return company property?
Illinois limits deductions from final compensation. Under 820 ILCS 115/9, an employer may deduct from a final paycheck only when the deduction is required by law, is to the employee’s benefit, responds to a valid wage assignment or court order, or is made with the employee’s express written consent given freely at the time of the deduction. Withholding an entire paycheck until equipment is returned does not fit those categories.
Is unused vacation always paid out in Illinois?
Earned, unused vacation is treated as final compensation and is paid at the worker’s final rate under 820 ILCS 115/2, which also bars policies that force forfeiture of earned vacation on separation. An employer may cap future accrual, but time already earned is payable. The Illinois PTO payout at termination article covers how accrual and payout are calculated.
How long do I have to file a claim for a late final paycheck?
A wage claim with the Illinois Department of Labor must be filed within one year of the date the final compensation was due, as Illinois Legal Aid Online explains. A civil lawsuit has its own, longer limitations period, but a worker may use the Department or the courts for the same wages, not both.
What does an employer owe for paying final wages late?
Under 820 ILCS 115/14, an employer that violates the Act owes the unpaid amount plus damages of 5% of the underpayment for each month it remains unpaid, and, when payment is ordered by the Department of Labor, a non-waivable administrative fee starting at $500. Willful refusal to pay can also carry criminal penalties.
