State of Illinois Employee Vacation Benefits: Accrual and Payout

Illinois does not require private employers to give paid vacation, but employee vacation benefits in Illinois are protected once an employer promises them: a policy, handbook, contract, or even a consistent practice turns vacation into earned wages under the Illinois Wage Payment and Collection Act. That means the time you’ve earned belongs to you, unused vacation must be paid out when you leave, and employers who refuse face financial penalties and, in willful cases, criminal charges.

When Vacation Becomes Earned Wages

No Illinois statute forces an employer to offer vacation, sick pay, holiday pay, or severance. Whether you get vacation at all, how much, and when you can use it are set by your employer.¹ Once the employer establishes a policy, though, the Illinois Wage Payment and Collection Act (IWPCA) treats promised vacation as earned compensation that must be honored like regular wages.²

The promise doesn’t have to be formal. Oral commitments, employee handbooks, internal memos, and consistent patterns of practice can all create an enforceable obligation to pay vacation.³

How Vacation Accrues

Accrual rates are up to your employer. Some companies grant a fixed annual allotment, some accrue by hours worked, and some use tiered systems that reward tenure. Whichever method your employer uses, the Illinois administrative code is clear: once vacation is tied to length of service, the time vests proportionally as you work.³

The pro-rata rule is where most disputes start. Say your employer grants five vacation days after one year of service, with a July 1 anniversary. If you leave on October 1 without using any of those days, you’re owed all five you earned on July 1, plus a pro-rata share for the three months you worked between July and September, equal to 25% of the next year’s allotment.¹

Employers can impose a waiting period before accrual begins. A policy that says no vacation accrues during your first 12 months is legal. But once accrual starts, the time earned belongs to you.

Use-It-or-Lose-It and Carryover

Illinois allows use-it-or-lose-it vacation policies, with two conditions: the policy must give you a reasonable opportunity to actually take the time, and the employer must show you had clear notice of the forfeiture rule.¹

Here’s the distinction that trips people up. A use-it-or-lose-it policy can eliminate unused vacation at year-end during ongoing employment. It cannot eliminate earned vacation at separation. Illinois regulations state directly that an employer cannot use a written policy to forfeit earned vacation when the job ends.³

Carryover rules vary. Some employers allow unlimited rollover, some cap it, and some allow none. If your employer permits unused vacation to accumulate, that growing balance is earned wages. An employer changing its vacation policy cannot claw back time already earned under the old one.⁴

Getting Paid for Unused Vacation When You Leave

Under the IWPCA, whenever a contract or policy provides for paid vacation, an employee who leaves without using all of it must receive the cash equivalent in their final paycheck. No policy or contract can require forfeiture of earned vacation upon separation.²

The payout is due by your next regularly scheduled payday after separation.⁵ It is calculated at your final rate of pay, not the rate you were earning when the vacation was originally accrued. If you earned vacation days two years ago at $20 an hour and are now making $25, the payout uses $25.

Collective bargaining agreements are the main exception. If a CBA governs your vacation terms, it can set different rules for payout at separation, and its terms control.²

The Paid Leave for All Workers Act

Since January 1, 2024, most Illinois employers have had to provide paid leave under the Paid Leave for All Workers Act (PLAWA). It isn’t vacation in the traditional sense, but it overlaps in practice: employees can use PLAWA leave for any reason, and employers can’t demand a reason for the request.⁶

Employees earn one hour of paid leave for every 40 hours worked, up to at least 40 hours per year. Accrual begins on the first day of employment, though employers can require a 90-day wait before you actually use it.⁴

If your employer already provides at least 40 hours of paid time off usable for any reason, they likely already comply with PLAWA and don’t need to add more on top.⁴ One caution at separation: vacation leave labeled as such may be subject to payout, but PLAWA leave standing alone may not carry the same payout obligation unless the employer’s policy designates it as vacation.

Some workers fall outside PLAWA entirely, including railroad employees covered by federal law, certain part-time and short-term college workers, and construction or parcel delivery employees covered by a collective bargaining agreement. School districts and park districts are excluded as covered employers.⁶

How Vacation Payouts Are Taxed

Vacation pay is compensation, subject to federal income tax withholding, Social Security tax, and Medicare tax.⁷

When vacation pay comes in your regular paycheck, withholding runs normally. When it arrives as a lump-sum payout at separation, the IRS classifies it as a supplemental wage, subject to a flat 22% federal income tax withholding rate. If your supplemental wages exceed $1 million in a calendar year, the excess is withheld at 37%.⁷ The higher withholding on a lump sum can look alarming, but it’s a withholding rate, not your actual tax rate. Any excess is reconciled when you file your return.

Vacation pay is reported on your Form W-2 with the rest of your compensation and should not appear in Box 11.⁸

If Your Employer Won’t Pay

You can file a wage claim with the Illinois Department of Labor (IDOL) through its online system. IDOL accepts claims for unpaid vacation pay along with unpaid regular wages, overtime, commissions, and illegal deductions.⁵

Two deadlines matter:

General IWPCA complaint to IDOL: within one year after the wages were due.²
Vacation-specific claims: within three years from the date the vacation was earned, under the administrative code.³

You can either file with IDOL or bring a civil lawsuit, but not both at the same time. A civil suit lets you recover attorney’s fees on top of the unpaid amount, which makes it viable even for modest sums when the employer’s refusal is clear-cut.²

What Employers Owe on Top of the Unpaid Amount

An employee who isn’t paid on time can recover the full unpaid amount plus damages of 5% of the underpayment for each month it remains unpaid. In an IDOL proceeding, that monthly penalty accrues until the Department issues a final order. In a civil case, the employee can also recover court costs and reasonable attorney’s fees.⁹

Willful refusal to pay carries criminal exposure. Unpaid amounts of $5,000 or less are a Class B misdemeanor; more than $5,000 is a Class A misdemeanor; a repeat offense within two years of a prior conviction is a Class 4 felony. Each day the violation continues counts as a separate offense.⁹ Criminal prosecution is rare in vacation disputes, but the statute gives IDOL leverage when employers stonewall.

FMLA Leave and Your Vacation Days

The Family and Medical Leave Act entitles eligible employees to up to 12 weeks of unpaid leave per year for qualifying medical or family reasons. FMLA leave is unpaid by default, but either you or your employer can substitute accrued paid vacation for some or all of the FMLA period, and the leave then counts as both paid vacation and FMLA-protected time.¹⁰ Your employer can require this substitution even if you would rather save your vacation days.

If Your Employer Goes Bankrupt

If your employer files for bankruptcy while owing you vacation pay, federal law gives you a limited priority claim. Unpaid vacation pay earned within 180 days before the bankruptcy filing is treated as a priority unsecured claim up to $17,150 per person, a cap most recently adjusted in April 2025 that covers wages, salary, commissions, and vacation pay combined.¹¹ Priority claims are paid before general unsecured creditors, which meaningfully improves your chances of recovering at least some of what you’re owed.
