California does not set a numerical cap on how much PTO you can carry from one year to the next, and it prohibits use-it-or-lose-it policies outright. Instead, the California PTO carryover limit is whatever accrual cap your employer sets, and that cap has to be reasonable. Most employers land somewhere between 1.5 and 2 times your annual accrual rate. Once you hit the cap you stop earning new hours until you use some, but nothing you already earned can be taken away.
Earned Vacation Is a Vested Wage
The rule that drives everything else sits in Labor Code Section 227.3. California treats vacation and PTO as deferred compensation. As you work, you earn a proportionate share of the benefit, and those hours vest the same way a paycheck does. An employer’s policy cannot cause that vested time to be forfeited, whether at year-end, on an anniversary date, or at any other trigger.1California Legislative Information. California Labor Code 227.3
That is what separates California from most of the country. The federal Fair Labor Standards Act does not require vacation at all and treats it as a matter of agreement between employer and employee.2U.S. Department of Labor. Vacations Once a California employer offers vacation or PTO, the state’s wage protections attach, and hours you have already earned cannot simply disappear at the end of the year.
Accrual Caps Are the Real Carryover Limit
Because forfeiture is off the table, employers use accrual caps to control balances. A cap sets a ceiling on how many hours you can hold at one time. When you reach it, you stop earning until you use some of what you have. The Division of Labor Standards Enforcement has confirmed that a reasonable cap is enforceable, as long as it is not being used as a backdoor way of denying benefits.3Division of Labor Standards Enforcement. Vacation
No statute fixes a specific ratio. The DLSE has historically treated a cap around 1.75 times an employee’s annual accrual as reasonable, and most California employers write policies in the 1.5 to 2 times range. If you earn 10 days a year, a cap between 15 and 20 days is standard. A cap set at 11 days on a 10-day annual accrual would look like a pretext for forfeiture and could draw a challenge from the Labor Commissioner.
The distinction between a cap and a use-it-or-lose-it policy is worth keeping straight. A cap freezes future accrual until you take some time off. A use-it-or-lose-it policy erases hours you already earned. The first is legal in California. The second is not.3Division of Labor Standards Enforcement. Vacation
Paid Sick Leave Carries Over Under Different Rules
Paid sick leave sits under Labor Code Section 246, not the vacation statute, and it has its own carryover math. 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. Unused sick leave carries over from year to year, but employers can cap total accrued sick leave at 80 hours or 10 days.4California Legislative Information. California Labor Code 246
Employers can also limit annual sick-leave use to 40 hours or 5 days even if your accrued balance is higher. And if the employer front-loads the full 40 hours or 5 days at the start of each year, no accrual or carryover is required.4California Legislative Information. California Labor Code 246
One more difference matters. Unused sick leave does not have to be paid out at separation unless the employer’s own policy says so. If you are rehired within 12 months, your previously accrued sick leave has to be restored.5Department of Industrial Relations. California Paid Sick Leave Frequently Asked Questions
Combined PTO Plans Get the Stronger Rule
Many California employers merge vacation and sick leave into a single PTO bank. Doing so has a legal consequence: because the plan includes vacation, the whole balance is treated under Section 227.3’s anti-forfeiture and payout rules. Your entire combined PTO balance carries over, subject only to the employer’s accrual cap, and it must be paid out when you leave.1California Legislative Information. California Labor Code 227.3
Employers that label a plan “PTO” but try to carve out the sick-leave portion from payout are on shaky ground. If the plan does not clearly separate vacation from sick leave, the Labor Commissioner will generally treat the full balance as vacation wages. Employees on combined plans usually come out ahead at the end.
What Happens to Your Balance When You Leave
When employment ends for any reason, the employer has to 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 some of your PTO was earned at $20 an hour and your final rate is $28, the whole balance pays at $28.
The one exception is a collective bargaining agreement that provides different payout terms. Outside of union contracts, the payout requirement is not negotiable.3Division of Labor Standards Enforcement. Vacation
Employers who willfully fail to pay out accrued vacation on time face waiting time penalties under Labor Code Section 203. The penalty is one day of wages for every day the final wages are late, capped at 30 days.6Department of Industrial Relations. Waiting Time Penalty For an employee earning $200 a day, a 30-day delay adds $6,000 on top of the underlying vacation payout. “Willful” does not require bad intent. A good-faith dispute over the amount can be a defense; simply forgetting to include PTO in the final check is not.
If the Employer Won’t Pay
If your employer refuses to pay out your accrued vacation or PTO, you can file a wage claim with the Labor Commissioner’s Office. Claims can be filed online, by email, by mail, or in person. You generally have three years from the date of the violation to file, or four years if the claim is based on a written employment contract.7Department of Industrial Relations. How to File a Wage Claim
After the claim is filed, the office investigates and usually schedules a settlement conference. If nothing resolves there, the case goes to a hearing where an officer takes evidence and issues a decision. Many claims settle before hearing, especially when waiting time penalties are running, because the employer’s exposure grows every day the wages sit unpaid.
