This guide covers PTO and vacation leave laws in Illinois for 2026. Whether you're an employee checking your rights or an HR team updating your handbook, here's what the law actually says — including payout rules, sick leave mandates, and what employers can and cannot do with your accrued time.
Does Illinois Require Employers to Provide PTO?
No U.S. state requires employers to provide paid vacation days — and Illinois is no exception. However, paid sick leave is a different matter: Illinois Paid Leave for All Workers Act (2024): 1 hour per 40 hours worked, up to 40 hours per year.
Once an employer promises vacation or PTO in a written policy or handbook, that promise becomes a legal obligation in virtually all states including Illinois. Courts consistently treat written PTO promises as binding wage commitments.

Carryover & Use-It-or-Lose-It Rules in Illinois
Forfeiture clauses are heavily restricted. Employers must honor handbook language on carryover.
Important distinction: an accrual cap (stopping new accrual when a balance ceiling is reached) is different from forfeiture (zeroing out earned PTO). Accrual caps are legal everywhere. Forfeiture of already-earned PTO requires careful attention to state law. See the Illinois PTO carryover rules page for full details.
