In Illinois, your final paycheck is generally due in full at separation — and no later than the next regularly scheduled payday — and it generally must include accrued unused vacation, paid out as earned wages. Illinois is often described as one of the stronger states for departing employees on final-paycheck rules: the Illinois Department of Labor (IDOL) explains that, under the Illinois Wage Payment and Collection Act (IWPCA), accrued unused vacation is generally treated as earned wages that an employer cannot forfeit at termination, regardless of what the employer's policy says. How this plays out depends on your situation, and the rules and figures below can change.
That feature alone is often what makes Illinois materially different from Texas, Florida, and most southern states — where employer policy more often controls vacation payout.
When is your final paycheck due in Illinois?
Here is how IDOL generally describes the landscape — your specific plan and agreement may differ:
- Timing: IDOL says final compensation is typically due in full at separation, and no later than the next regularly scheduled payday for the pay period in which the separation occurred.
- Vacation/PTO — earned wages: Under IWPCA § 5, IDOL generally treats accrued unused vacation as a wage owed at termination, payable at the final rate of pay. A "use-it-or-lose-it" policy can generally cap future accrual, but IDOL says it cannot retroactively forfeit vacation already earned.
- Commissions: Earned commissions are generally due by the next regular payday after they become due. Plans with "still employed" clauses tend to be scrutinized but may be enforceable if clearly written — the specifics depend on your plan.
- Method: Check, direct deposit (if previously authorized), or payroll debit card. IDOL generally treats payment as something an employer cannot condition on returning property first.
- Deductions: IWPCA generally limits deductions to those required by law, those the employee has authorized in writing, or those for the benefit of the employee. Damaged-property or unreturned-equipment deductions are generally not allowed without specific written authorization.
Scripts people commonly use
These are phrasings some people use when raising final pay with an employer — adapt them to your situation:
To request final pay including vacation:
"Under the Illinois Wage Payment and Collection Act, my final wages — including accrued unused vacation at my final rate — are due no later than the next regularly scheduled payday. My current vacation balance is [N] hours. Please confirm the amount and payment date."
When the employer claims vacation is forfeited on separation:
"Illinois law treats accrued vacation as earned wages. Under IWPCA, a policy of forfeiture at termination is not enforceable as to already-earned vacation. Please include my full accrued balance of [N] hours in my final paycheck."
When the employer threatens deduction for unreturned property:
"Under IWPCA § 9, deductions from wages require written authorization at the time the deduction is made. I have not given such authorization. Please issue my final paycheck in full. We can address property return separately."
What should you document?
- Last day of employment and the next regular payday
- Your accrued vacation/PTO balance and the rate at which you earned it
- Your commission plan, including any "earned" definition
- Pay stubs showing the running vacation accrual through your last day
- All written communications about the amount and timing of your final pay
What can you do if your pay is late or short?
If the employer is late or short, common steps people take include:
- Filing a wage claim with the Illinois Department of Labor. IDOL offers online filing, with no filing fee and no attorney required.
- IDOL investigates, holds a hearing if necessary, and can order payment plus statutory penalties.
- Larger or more complex claims may be filed directly in court. The IWPCA generally allows recovery of attorney's fees, interest, and a statutory damages multiplier on underpaid wages. That multiplier has varied over time — historically 2% per month and later amended (5% per month under post-2021 amendments to 820 ILCS 115/14) — so it often helps to confirm the current rate with IDOL or counsel before relying on a specific figure.
- Some people consult an employment attorney for systemic issues (multi-employee underpayment, commission disputes over six figures, retaliation tied to wage complaints).
Chicago workers may also want to check the Chicago Paid Sick Leave Ordinance and any local wage-payment ordinances; these can add additional payout requirements beyond state law, and your local rules may differ.
