Illinois: Final Paycheck Deadlines
The short answer
Illinois uses one rule regardless of how the job ends: final compensation is due at separation if possible, but no later than the next regularly scheduled payday, for both a firing and a quit. Earned, unused vacation must be paid out as part of that final compensation, and a policy that tries to forfeit it is void. A shortchanged employee can file a wage claim with the Department of Labor or sue (not both), recovering the unpaid amount plus 5% of it for every month it stays unpaid; a willful, able-to-pay refusal to pay can be prosecuted as a misdemeanor or, on repeat, a felony.

| Governing law | Illinois Wage Payment and Collection Act, 820 ILCS 115/5 (final-compensation deadline and vacation payout); 115/14 (penalties); 115/11 (Dept. of Labor wage-claim process) |
|---|---|
| Deadline if fired or laid off | Final compensation is due in full at the time of separation if possible, but in no case later than the next regularly scheduled payday for that employee (820 ILCS 115/5) |
| Deadline if the employee quits | Same deadline as a discharge — the statute uses the single term "separated employees" and draws no distinction between quitting and being fired (820 ILCS 115/5) |
| Unused vacation/PTO payout required? | If an employment contract or policy provides paid vacation, the monetary equivalent of all earned, unused vacation must be paid as part of final compensation at the employee's final rate of pay, and no contract or policy may provide for its forfeiture — unless a collective bargaining agreement provides otherwise (820 ILCS 115/5) |
| How final pay must be delivered | Final compensation must be paid in lawful U.S. money — by check redeemable at a bank without discount, by deposit to an account the employee designates, or by a compliant payroll card; an employer can't designate one bank as the exclusive place of payment (820 ILCS 115/4). On the employee's written request, the final check must be mailed (820 ILCS 115/5) |
| Penalty for a late or unpaid final check | An underpaid employee recovers the unpaid amount plus damages of 5% of it for each month it remains unpaid, through a Department of Labor claim or a civil action (not both); a civil action also adds costs and attorney's fees (820 ILCS 115/14(a)). A willful, able-to-pay refusal to pay is a Class B misdemeanor (unpaid amount ≤$5,000) or Class A misdemeanor (>$5,000) on conviction, and a Class 4 felony for a repeat violation within 2 years (820 ILCS 115/14(a-5)) |
| How to enforce it | File a wage claim with the Illinois Department of Labor within one year of when the final compensation was due, or sue in circuit court — not both (820 ILCS 115/11, 115/14(a)). Corporate officers or agents who knowingly permit a violation are personally liable as the employer (820 ILCS 115/13). An employer that ignores a Department demand or order also owes a separate administrative fee, a 20% penalty to the Department, and a 1%-per-day penalty to the employee (820 ILCS 115/14(b)) |
| Exceptions and special rules | A valid collective bargaining agreement can override both the vacation no-forfeiture rule and the ordinary pay-period timing rules the Act otherwise sets (820 ILCS 115/4, 115/5). The Act doesn't cover state or federal government employees, or individuals who meet its 3-part independent-contractor test (820 ILCS 115/1, 115/2) |

Requirements one by one
Final pay uses the same deadline for a firing or a quit
Section 5 says: "Every employer shall 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 such employee." Because the rule
uses "separated employees" without splitting resignations from terminations,
the same outside deadline applies to both.
A promised vacation benefit cannot be forfeited at separation
The statute requires "the monetary equivalent of all earned vacation" at the
employee's final rate and says no employment contract or policy may forfeit
earned vacation at separation. That rule applies when the employer has chosen
to provide paid vacation through a contract or policy; it does not itself
require every employer to offer vacation. A collective bargaining agreement
may provide a different rule.
The monthly damages can be calculated from the unpaid balance
Section 14 adds damages equal to 5% of the underpayment for each month it
remains unpaid. For example, if $1,000 remains unpaid for three months, the
statutory monthly-damages component is $150, in addition to the $1,000 itself.
A civil action also permits recovery of costs and reasonable attorney's fees.
What trips people up
The employee must choose one recovery track. Section 14 permits recovery
through a Department of Labor claim or a civil action, "but not both." The
Department complaint itself must be filed within one year after the final
compensation was due; HB 4214 would extend that administrative window to three
years, but it remains pending.
Ignoring an order creates additional liabilities. After the deadlines in
§ 14(b), an unpaid Department demand or administrative or court order can add a
20% penalty payable to the Department and a 1%-per-calendar-day penalty payable
to the employee, separate from the ordinary monthly damages.
Common questions
Does Illinois require an employer to offer paid vacation?
No. Section 5 controls the payout only when a contract or employment policy
provides paid vacation.
Can the employee require the final check to be mailed?
Yes. Section 5 requires the employer to mail a final-compensation check when
the employee makes that request in writing.
Can a corporate officer be personally responsible?
Yes. Section 13 treats an officer or employer agent who knowingly permits a
violation as the employer for purposes of the Act.
