Whether your PTO rolls over to next year depends on the state you work in and what your employer’s written policy says. No federal law requires paid time off in the first place, so there’s no federal rule guaranteeing carryover either.1U.S. Department of Labor. Vacation Leave About a dozen states, however, treat earned vacation as wages that belong to you the moment you accrue them, which effectively outlaws use-it-or-lose-it deadlines. In every other state, the answer lives in your employee handbook or contract.
States Where Your PTO Cannot Be Taken Away
A use-it-or-lose-it policy forces you to forfeit hours you haven’t spent by year-end. Several states have banned that practice by classifying earned vacation as a form of wages. The reasoning is simple: once you’ve done the work that earned the time off, the benefit is yours, the same way your paycheck is yours.
California is the clearest example. State law provides that when an employer offers paid vacations, vested vacation time cannot be forfeited, and any unused balance must be paid at your final rate of pay when you leave. Colorado requires employers to pay all “earned and determinable” vacation upon separation and bars any agreement waiving that right. Illinois and Massachusetts also prohibit forfeiture of earned vacation. Nebraska requires payment of all unused accumulated vacation when an employee retires, is dismissed, or voluntarily leaves. Montana blocks employers from divesting vacation once it has been earned under an employment agreement. Louisiana, New Mexico, and Rhode Island each require payout of accrued vacation at termination, which produces the same practical result.
If you work in one of these states, your employer cannot wipe out your balance on December 31. It can, however, limit how much you accumulate in the first place.
Accrual Caps Are Legal Even Where Forfeiture Isn’t
Many employers control PTO growth with an accrual cap rather than a year-end deadline. A cap sets a maximum balance you can hold at any time. When you hit the ceiling, new hours stop building until you use some of what you have. The legal distinction that matters: a cap pauses future accrual but does not erase time you already earned.
This structure is accepted even in states that ban forfeiture. California’s labor enforcement agency has indicated that a cap set at roughly 1.75 times the annual accrual rate is generally reasonable. If you earn 80 hours a year, a cap around 140 hours would likely hold up. A cap set so low that meaningful time off is impossible could be challenged as disguised forfeiture.
Check your pay stubs or HR portal if you’re near a cap. Once you hit it, every pay period you work without taking time off is a pay period you’re accruing nothing.
When Your Employer Rewrites the Rollover Rules
Employers can change PTO policies, including rollover allowances, but the change has to be prospective. New rules apply to hours you earn going forward. Your employer cannot retroactively strip away PTO you already banked under the old policy. If you accumulated 60 hours when the policy allowed full rollover, moving to a 40-hour cap doesn’t erase those 60 hours. You still get to use or be paid for them.
No federal notice period governs these changes, but the new policy must be clearly communicated before it takes effect. If your employer announces a stingier rollover rule, look at the effective date and whether it leaves you time to use hours that would exceed the new cap. In states that treat vacation as wages, an attempted retroactive confiscation would run into the same legal walls as a use-it-or-lose-it policy.
Sick Leave Rolls Over Under a Separate Set of Rules
Sick leave and general PTO are often lumped together in conversation, but the legal frameworks are different. Many states and cities have paid sick leave laws with their own carryover requirements. A common structure lets employees accrue one hour of sick leave per 30 to 40 hours worked, and then requires the employer to allow at least 40 hours of unused sick time to carry into the next year.
Some of these laws give employers a way out: if you frontload the full annual allotment on day one of the year, you can skip the rollover requirement. The reasoning is that a frontloaded bank already gives the employee full access, so carryover adds nothing.
These laws are relatively new and vary from one jurisdiction to the next, so the ordinance that governs your specific city or state is what determines your carryover rights on the sick leave side.
Unlimited PTO and Whether There’s Anything to Roll Over
Unlimited PTO plans appear to make the rollover question moot. With no fixed bank, there’s nothing to carry forward and nothing to pay out at termination. That’s not always how it plays out legally.
A California appellate court took up this issue in McPherson v. EF Intercultural Foundation, Inc. The employer called its policy unlimited, but the court found the policy was never put in writing, employees were discouraged from taking time off during busy periods, and the practical ceiling was about 20 days a year. Because the policy operated like a capped benefit, the court held that vacation had vested and had to be paid out at termination under the state’s wage protection law.2Justia Case Law. McPherson v EF Intercultural Foundation Inc
The court didn’t say every unlimited PTO plan creates vested rights. A genuinely unlimited plan might avoid payout obligations if the employer puts the policy in writing, states clearly that PTO is a flexible schedule rather than deferred compensation, spells out rights and obligations, and gives employees real opportunity to use time off. Under an unlimited plan, the written policy language matters far more than the label.
What Happens to Unused PTO When You Leave
Even in states without a forfeiture ban, you may still be entitled to cash for your unused balance when your employment ends. Roughly 20 states require some form of vacation payout at termination. Some require it in every case; others require it only when the employer’s written policy is silent on the point.
Penalties for skipping the payout can be significant. Several states let employees recover double the unpaid amount as liquidated damages, plus attorney’s fees and costs. Some jurisdictions add daily penalties for willful nonpayment that keep accruing until the employer pays. If you believe your employer wrongly withheld a PTO payout, you can typically file a wage claim with your state’s labor department or take the claim to court.
Contracts and Union Agreements Can Give You More
An individual employment contract or a collective bargaining agreement can create rollover rights beyond what state law requires. If your signed agreement guarantees carryover of a specific number of hours, that promise is enforceable even in states that otherwise allow use-it-or-lose-it policies. The contract creates its own binding obligation.
If your employer violates those terms, you or your union can file a grievance or bring a breach-of-contract claim to recover the value of the lost time. Contract language generally overrides an employee handbook, which courts often treat as guidance rather than a binding promise. When a signed agreement and a handbook conflict on rollover, the signed agreement controls. Read the vesting and carryover language in your own agreement closely; that’s where your actual rights live.
