Does Illinois Require Employers to Pay Out PTO?

Illinois does require employers to pay out earned, unused vacation time when an employee leaves, whether the departure is a quit, a firing, or a layoff. The Illinois Wage Payment and Collection Act treats that unused vacation as part of your final compensation, on par with unpaid wages.¹ Whether every category of paid time off gets the same treatment depends on how your employer set up its policy, and the structure matters more than most people expect.

What Has to Be Paid Out

Section 5 of the Wage Payment and Collection Act is the operative rule. When an employment contract or company policy provides paid vacation and you leave with earned time still on the books, the employer must pay you the monetary equivalent at your final rate of pay.¹ The statute also bars any contract or policy from forcing forfeiture of earned vacation at separation.

The protection is narrower than the word “PTO” suggests. The statute specifically shields “earned vacation.” Sick leave and personal days generally do not have to be paid out unless the employer’s own policy defines them as vacation or as earned wages.²

If a collective bargaining agreement handles vacation payout differently, the agreement controls. The statute applies “[u]nless otherwise provided in a collective bargaining agreement,”¹ so union-covered employees should read their contract first.

Combined PTO Banks

How the leave is bucketed can decide the whole question. If an employer lumps vacation, sick time, and personal days into one undifferentiated PTO account, the entire bank may be treated as vacation for payout purposes. Cook County’s Paid Leave Ordinance makes this explicit: any leave credited to an employee’s “paid time off bank” or “vacation account” must be paid out, while leave tracked in a separate non-vacation bank is not subject to the same requirement.³ Employers who want to avoid paying out sick time have a strong incentive to keep those accounts separate.

Paid Leave for All Workers Act Hours

Since January 1, 2024, the Illinois Paid Leave for All Workers Act has required most employers to provide at least 40 hours of paid leave per year that employees can use for any reason. This leave, on its own, does not have to be paid out at separation. The Act says nothing in it “shall be construed as requiring financial or other payment to an employee from an employer upon the employee’s termination, resignation, retirement, or other separation from employment for paid leave accrued under this Act that has not been used.”⁴

But if the employer credits those Paid Leave for All Workers Act hours into an existing PTO bank or vacation account, the payout requirement snaps back into place, and any unused leave must be paid out to the same extent as vacation under the Wage Payment and Collection Act.⁴ The Illinois Administrative Code confirms the same: kept separate, no payout; combined with vacation, payout required.⁵

Use-It-or-Lose-It Rules

Illinois does allow use-it-or-lose-it vacation policies during employment. An employer can require you to take vacation by a certain date or lose it. The Illinois Administrative Code permits this if two conditions are met: you had a reasonable opportunity to actually take the vacation, and the employer can show you had notice of the policy.⁶ The Illinois Department of Labor confirms this reading in its published guidance.²

What an employer cannot do is force forfeiture at separation. “Use your 2025 days by December 31 or they expire” is legal if the conditions above are met. “Any unused vacation disappears when you leave the company” is not. Once vacation has been earned under the employer’s own policy and has not expired under a valid use-it-or-lose-it clause, it must be paid out.⁶

How Much You Have Earned

The Wage Payment and Collection Act protects vacation earned “in accordance with” the employer’s contract or policy, which gives the employer real control over the accrual side. Employers can set accrual rates, require a waiting period before any vacation begins to accrue, or cap the total you can bank. Those policy choices determine how much vacation exists to pay out.

The Illinois Department of Labor uses this example: if a policy grants one vacation day per month worked and an employee leaves after three months having already taken three days, the employer owes nothing. If the same employee took no days off, the employer owes three days’ pay.² The policy sets the schedule; the law protects whatever has been earned under it.

Calculating the Payout

Multiply your accrued, unused vacation hours by your final hourly rate. If you’re salaried, convert your salary first — annual salary divided by 2,080 for a standard 40-hour week, or whatever hours your position calls for. The statute requires payment at your “final rate of pay,” so a recent raise applies.¹

Under federal overtime rules, a vacation payout is not treated as hours worked, so it doesn’t inflate your regular rate for overtime calculation, and the employer can’t use it to offset overtime it owes.⁷

When You Should Receive the Money

Your vacation payout is part of your final compensation, and final compensation must be paid at the time of separation if possible, and no later than the next regularly scheduled payday.⁸ That rule applies whether you quit or were fired. If your employer runs biweekly payroll and you leave on a Wednesday, expect the payment by the next regular payday, not weeks later.

How the Payout Is Taxed

A vacation payout is taxable income, and the withholding can look steep. For federal income tax, lump-sum payouts count as supplemental wages, which employers can withhold at a flat 22% (or 37% if your total supplemental wages for the year exceed $1 million) instead of your normal bracket. Social Security at 6.2% and Medicare at 1.45% apply on top, and so does Illinois income tax. The heavier withholding doesn’t mean you owe more tax overall — any overwithholding comes back when you file your return.

What You Can Recover If the Employer Won’t Pay

Illinois adds real teeth to the payout requirement. An employee who doesn’t receive timely final compensation can recover the full unpaid amount plus damages of 5% of the underpayment for every month it remains unpaid.⁹ On $3,000 in unpaid vacation, that’s $150 in penalty damages every month the employer stalls.

If you go the civil lawsuit route rather than administrative, you can also recover attorney’s fees and court costs on top of the unpaid amount and the 5% monthly penalty.⁹ Fee-shifting matters because it means an attorney may take your case even when the raw dollar amount is modest; if you win, the employer pays the legal bills.

How to File a Claim

You have two routes: file an administrative complaint with the Illinois Department of Labor, or file a civil lawsuit. You cannot do both. The statute makes you pick one.⁹

Filing With the Illinois Department of Labor

The IDOL accepts wage complaints online (an Illinois ID account is required), by email at DOL.Wages@Illinois.gov, or by mailing a paper form to the Chicago office.¹⁰ You must file within one year of the date the wages or final compensation were due, and even within that window, the Department only investigates the three years before the filing date. For a vacation claim, the IDOL specifically asks for a copy of the written policy or a written explanation of it.¹¹

Filing a Civil Lawsuit

A lawsuit lets you recover attorney’s fees and court costs, which the administrative process doesn’t, and it lets you pursue the 5% monthly penalty damages. The tradeoffs are the up-front cost and the longer timeline. The choice often turns on how much is at stake and how cooperative the employer looks.

What to Gather Before You File

Your case is only as strong as your documentation. Start collecting before you leave, or as soon as you can after:

Pay stubs and W-2s, which establish your rate of pay and the employer relationship.
The written vacation or PTO policy, whether from the handbook, offer letter, or intranet.
Accrual records — HR portal screenshots, emails confirming your balance, or any documentation showing what you had banked.
Communications where you asked about the payout or the employer acknowledged your balance.

Federal law requires employers to keep payroll records for at least three years,¹² so if your own copies are thin, the employer likely still has records that can be compelled during an investigation or lawsuit.

If Your Employer Files for Bankruptcy

Bankruptcy doesn’t automatically wipe out your claim. Under federal bankruptcy law, unpaid wages including earned vacation pay get priority status when the employer’s remaining assets are distributed. For 2026, the priority cap is $17,150 per employee, applied to wages earned within 180 days before the bankruptcy filing or the date the business stopped operating, whichever came first.¹³ Priority status puts you ahead of general unsecured creditors like suppliers and landlords. It doesn’t guarantee full payment from a company with nothing left, but it moves you closer to the front of the line.
