Use-It-or-Lose-It PTO: How Forfeiture Policies Work and Where They're Restricted
What Use-It-or-Lose-It PTO Actually Means
A use-it-or-lose-it policy sets a hard deadline, most commonly December 31 or the employee's hire-date anniversary, after which any unused accrued PTO balance is forfeited entirely - it does not carry into the new year and is not paid out. This is different from an accrual cap, which pauses further accrual once a balance reaches a ceiling but doesn't erase what's already been earned; see our guide on how PTO accrual works for that distinction.
Employers use forfeiture policies to control liability - unused PTO sits on the books as an accrued expense, and unlimited rollover can let balances grow indefinitely. But because many states treat earned PTO as a form of wages once it accrues, an outright 'use it or lose it' rule that erases already-earned time can be illegal in those states, regardless of how clearly the policy is written or communicated.
Where Forfeiture Is Restricted or Prohibited
California is the most frequently cited example: under California law, earned vacation/PTO is treated as vested wages the moment it accrues, and an employer cannot take it away through a use-it-or-lose-it policy - a carryover cap that limits how much can roll forward is allowed, but flat forfeiture of already-earned time is not.
Nebraska similarly treats accrued vacation leave as wages once earned, restricting outright forfeiture in comparable ways to California. Montana also has restrictions specific to earned vacation time being treated as wages, though the exact boundaries differ from California's rule and should be confirmed directly with the state before relying on it. This is not an exhaustive list of every state with some form of restriction - if you operate in a state not named here, verify its specific position before writing a forfeiture clause into your policy.
The Legal Alternative: A Carryover Cap Instead of Zero Carryover
Where outright forfeiture is restricted, employers commonly use a carryover cap instead: unused days up to a set limit roll into the new year, and only the amount above that cap is forfeited (or paid out, depending on state law and the written policy). This preserves the goal of preventing unlimited balance growth without erasing already-earned time entirely.
A typical structure: 1.25 days/month accrual (15 days/year), a 15-day accrual cap, and a 5-day carryover cap. An employee ending the year with 8 unused accrued days carries over 5 into the new year; the remaining 3 are handled according to the written policy and applicable state law - forfeited where legally allowed, paid out where required or chosen. See our guide on PTO carryover rules for the full worked example of this calculation.
Designing a Use-It-or-Lose-It Policy for a Small Business
If you're outside a restricted state and want to use forfeiture, the policy should specify the exact forfeiture date, whether it applies to the calendar year or the employee's hire anniversary, how much advance notice employees get before the deadline (common practice is reminding employees at least 60-90 days out), and whether any exceptions apply (medical leave, approved deferrals, etc.).
If you're in a restricted state, or want to avoid the legal exposure of a forfeiture clause entirely, a carryover cap achieves a similar business goal - preventing balances from growing without limit - without the risk of an unenforceable clause. Our free PTO accrual calculator (tabletemplates.com/free/pto-accrual-calculator-excel/) lets you model both a cap-only structure and a forfeiture-date structure against real accrual numbers before you commit to either in writing.
Frequently asked questions
Is use-it-or-lose-it PTO legal?
It depends on the state. In states that treat accrued PTO as earned wages, like California and Nebraska, outright forfeiture of already-earned time is generally not legal, though accrual caps and carryover caps are. In most other states, a clearly written and communicated forfeiture policy is legal.
What states ban use-it-or-lose-it PTO?
California and Nebraska are the most consistently cited states that prohibit forfeiting already-accrued PTO because they classify it as earned wages. Montana has its own restrictions on earned vacation time. This isn't an exhaustive list - verify your specific state before relying on it.
What's the difference between a use-it-or-lose-it policy and a carryover cap?
Use-it-or-lose-it forfeits the entire unused balance at a fixed date. A carryover cap lets a limited number of days roll into the new year and only forfeits (or pays out) the amount above that cap - it's a milder, and in many restricted states, legally safer alternative.
Can an accrual cap and use-it-or-lose-it work together?
They're different mechanisms and can coexist, but they're not the same thing. An accrual cap pauses new accrual once a balance hits a ceiling; use-it-or-lose-it erases the balance on a calendar date regardless of whether a cap was ever reached.
How much notice should employees get before a use-it-or-lose-it deadline?
There's no universal legal requirement, but 60-90 days' written notice before the forfeiture date is common practice and reduces disputes, even in states where forfeiture itself is legal.
Does a spreadsheet or tracker enforce carryover caps automatically?
A well-built one does - our free PTO accrual calculator applies a carryover cap in its formulas so you can see the year-end math before committing it to policy, and LeaveSheet applies the same capped-carryover logic automatically for an entire team.
This guide is general information for small-business owners, not legal advice. Use-it-or-lose-it and forfeiture rules vary by state and change over time - confirm current rules with your state labor department or an employment attorney before writing a forfeiture clause into policy.
