Use It or Lose It PTO: How to Book Your Leftover Days Before December 31
Use it or lose it PTO means unused days disappear at the end of the year if your policy says so. Check your balance and the policy line in October, while days can still be approved, then book them.
Use it or lose it PTO is a policy where vacation days you do not take by a set date, usually December 31, are gone. Whether it applies to you depends on your company's policy and, in a few states, on state law. The practical part is timing: in October there are still enough weeks to spread your leftover days and get them approved. In mid-December, everyone on your team is asking for the same days.
What use it or lose it actually means
Most pages about use it or lose it PTO are written for employers, about whether the policy is legal. This one is for the person with days left over.
A use it or lose it policy says that vacation or PTO you have not taken by a cutoff date is forfeited. The cutoff is usually December 31, or the end of your company's benefits year. Federal law does not require paid vacation for most jobs, as Mercer notes, so the rules come from your employer's policy and, in some states, from state law.
Your policy usually does one of four things with unused days:
- Forfeits them at the cutoff. This is the true use it or lose it.
- Carries some over, up to a cap, for example five days, and forfeits the rest.
- Caps accrual, so you stop earning new days once your balance hits a ceiling. Nothing is taken away, but you stop earning.
- Pays them out, at year end or when you leave.
The line that tells you which one is in your employee handbook or on the time-off page of your HR system. Find it before you plan anything.
The states where earned vacation cannot be taken away
A few states treat earned vacation like earned wages. A Mercer survey of state laws lists California, Colorado and Montana as states that bar forfeiting vacation that has already been earned. In Colorado, the state Supreme Court ruled in 2021 that earned vacation must be paid out when you leave, regardless of company policy, as The Colorado Sun explains. Nebraska is often listed with these states too; Mercer marks its rule as unclear.
Two things still apply in those states. Employers can cap accrual, so you stop earning once you hit the ceiling. And the protection covers vacation you have earned, not days you have not accrued yet. This is general information, not legal advice. If your balance is large and the stakes are real, ask HR how the policy applies to you, or check with your state's labor department.
How to use your leftover days, step by step
1. Check your balance in October
Open your HR system and write down three numbers: days available now, days you will still accrue before the cutoff, and days already approved but not taken. Add the first two and subtract the third. That is your real balance.
2. Read the policy line
Find out whether you lose everything, carry some over or get paid out. If you can carry five days, you only need to plan the rest.
3. Spread the days, then ask early
Look at the weeks left and spread the days out. Long weekends are often easier to get approved than a full week in late December, when many people want the same days off. Thanksgiving week (Thanksgiving Day is November 26, 2026) and the last week of December are the usual crunch.
4. Get the approval in writing
Submit the request in your HR system rather than agreeing on it in a hallway, so the approval is on record. If a manager denies days near the cutoff, ask in writing whether they can be carried over.
Let Tracy keep the balance and the deadline
You see your PTO balance once, on a busy day, and then forget it until December. Tracy, the assistant in dEssence, can keep it in front of you.
Take a screenshot of your time-off balance and of the policy line about carryover, and send them to Tracy in Telegram, Chrome or on the web. She reads the balance and the cutoff date and keeps them together. Ask her to remind you to put in the request, and she does. Ask her "how many days do I have left, and what happens to them?" and she answers from what you sent.
She does not see your HR system and does not submit requests for you. If your balance changes, send a new screenshot and she keeps the latest one.
Frequently asked questions
Is use it or lose it PTO legal?
In most states, yes, if the policy is written down and employees know about it. California, Colorado and Montana do not let employers take away vacation that has already been earned. Nebraska is often listed with them, but its rule is less clear. Employers in those states can still cap how much you accrue.
What happens to unused PTO at the end of the year?
It depends on your policy. It may be forfeited, carried over up to a cap, or paid out. The rule is in your employee handbook or on the time-off page of your HR system.
Can my employer deny PTO and then make me lose it?
In many states a manager can deny specific dates, and the policy still applies at the cutoff. If a request near the cutoff is denied, ask in writing whether the days can be carried over. In states that bar forfeiture, earned days stay yours.
When should I request PTO for the holidays?
As early as you can, ideally in October. Thanksgiving week and the last week of December are popular, and on some teams requests are approved first come, first served.
Do I get paid for unused vacation when I leave?
Some states require payout of earned vacation when you leave, including California and Colorado. In other states it depends on your employer's written policy.
