California does not have a statutory PTO carryover limit, and it does not allow use-it-or-lose-it policies either. Once you earn vacation or PTO, it is a vested wage that cannot be wiped out at year-end. What your employer can do is set a reasonable accrual cap: when your balance hits the ceiling, you stop earning more hours until you use some. In practice, that cap is usually 1.5 to 2 times your annual accrual rate, and it functions as the real carryover limit in California.
Earned PTO Is a Vested Wage
Under California Labor Code Section 227.3, vacation time is deferred compensation. As you work, you earn a proportionate share of your vacation benefits, and those hours vest the same way wages do. A policy cannot provide for forfeiture of vested time, whether at year-end, on a schedule change, or at any other point.1California Legislative Information. California Labor Code 227.3
That classification is what sets California apart. The federal Fair Labor Standards Act does not require employers to offer vacation at all, and treats any vacation benefits as a matter of agreement between employer and employee.2U.S. Department of Labor. Vacations In California, once an employer offers vacation or PTO, state wage protections apply, and earned hours cannot simply disappear.
Accrual Caps Are the Real Carryover Limit
Although earned vacation can never be forfeited, employers can set a ceiling on how much you accumulate. This is the accrual cap, and it functions as California’s version of a carryover limit. When your balance reaches the cap, you temporarily stop earning new hours until you use some of what you have. The DLSE has confirmed that a reasonable cap is enforceable, so long as it is not a disguised way of denying employees their benefits.3Division of Labor Standards Enforcement. Vacation
The key word is “reasonable.” No statute fixes a specific ratio, but the DLSE has historically treated a cap around 1.75 times an employee’s annual accrual rate as reasonable. Most California employers land somewhere between 1.5 and 2 times the annual rate. If you earn 10 days of PTO per year, a cap of 15 to 20 days is typical. A cap of 11 days on a 10-day annual accrual would invite a challenge from the Labor Commissioner, because it would effectively pressure employees into losing time.
Cap vs. Use-It-or-Lose-It
The difference matters. A cap stops you from earning more until you take some time off; the hours you already have stay on the books indefinitely. A use-it-or-lose-it policy wipes out hours you already earned. The first is legal in California. The second is not.3Division of Labor Standards Enforcement. Vacation
So if your employer tells you unused PTO expires on December 31, that policy is unenforceable. If your employer tells you that you’ve stopped accruing because you’ve hit the cap, that is likely enforceable, assuming the cap is set at a reasonable multiple of your annual rate.
Waiting Periods Before Accrual Starts
Employers can delay the start of vacation accrual. A probationary or introductory period during which no vacation is earned is permissible, and it can even extend through the entire first year of employment. The DLSE will recognize the waiting period as valid only if it is genuine, not a device to cheat employees out of time they would otherwise have earned.3Division of Labor Standards Enforcement. Vacation
The test is practical: if the accrual schedule after the waiting period makes it obvious the employer is backloading time that should have been earned earlier, the Labor Commissioner will treat the waiting period as invalid. An employer that offers zero vacation in year one and then four weeks in year two is clearly shifting year-one vacation into year two. An employee who leaves during a sham waiting period would still be entitled to prorated vacation pay.
Paid Sick Leave Follows Different Rules
Paid sick leave is not governed by Section 227.3 and does not follow the same carryover rules. Under Labor Code Section 246, and since SB 616 took effect on January 1, 2024, employers must provide at least 5 days or 40 hours of paid sick leave per year. Accrued sick leave carries over from year to year, but employers can cap total accumulation at 80 hours or 10 days. Employers can also limit annual use to 40 hours or 5 days even when your balance is higher, and if the full year’s allotment is front-loaded at the start of each year, no accrual or carryover is required at all.4California Legislative Information. California Labor Code 246
One more distinction worth knowing: unused sick leave does not have to be paid out when you leave your job, unless the employer’s own policy says otherwise. If you are rehired by the same employer within 12 months, your previously accrued sick leave must be restored.5Department of Industrial Relations.

Combined PTO Plans Change the Picture
Many California employers combine vacation and sick leave into a single PTO bucket. That simplifies scheduling, but it has a legal consequence: because the combined plan includes vacation, the entire balance falls under Section 227.3’s anti-forfeiture and payout rules. When you leave a job with a combined PTO plan, the employer must pay out all accrued and unused hours, including whatever portion might have been labeled sick leave under a separate policy.1California Legislative Information. California Labor Code 227.3
Employers sometimes try to label a policy “PTO” while exempting the sick-leave portion from payout. That is a shaky position. If the plan does not clearly separate vacation from sick leave, the Labor Commissioner will likely treat all of it as vacation wages. Employees with combined PTO plans generally come out ahead at separation compared to those with separate buckets.
Your Carryover Balance at Separation
Whatever you have carried forward, you keep. When employment ends for any reason, whether you quit, are fired, or are laid off, your employer must pay out all accrued and unused vacation or PTO. The payout is calculated at your final rate of pay, not the rate you were earning when the hours accrued.1California Legislative Information. California Labor Code 227.3 If part of your balance was earned at $20 an hour and your final rate is $28 an hour, the entire balance is paid at $28.
The one exception: if you are covered by a collective bargaining agreement that provides otherwise, different payout terms may apply. Outside of union contracts, the payout requirement is non-negotiable.3Division of Labor Standards Enforcement. Vacation That is why the carryover question in California is less about what you can keep on the books and more about what the cap allows you to accumulate in the first place. The hours themselves are safe. The cap controls how many you ever get to.
