California PTO accrual laws start from one principle that drives everything else: once an employer offers paid time off, every hour an employee earns is treated as wages already earned. The state does not require employers to offer PTO at all, but any policy they do adopt has to work within that wage classification. That means no forfeiture of accrued time, limited use of accrual caps, and full payout of unused hours when employment ends.
PTO Is Wages Under California Law
Earned vacation time is considered wages, and it vests as labor is performed.1Department of Industrial Relations. Vacation FAQ The California Supreme Court established this in Suastez v. Plastic Dress-Up Co., holding that vacation pay “is not a gratuity or a gift, but is, in effect, additional wages for services performed.”2Supreme Court of California. Suastez v Plastic Dress-Up Co PTO is legally identical to money sitting in a paycheck. It cannot be revoked, and the Labor Commissioner enforces it using the same tools that apply to any other unpaid wages.
How Accrual Works
Most California employers use one of two systems. Under the accrual method, employees earn PTO gradually based on time worked. A common formula is one hour of PTO for every 30 hours worked, though employers can set different rates such as a fixed number of hours per pay period or per month of service. The right to that time vests immediately as it is earned, so it becomes the employee’s property the moment it accrues.1Department of Industrial Relations. Vacation FAQ
Under a front-loading method, the employer grants the full annual PTO allotment at the start of the year or on the employee’s hire anniversary. Front-loading avoids the running accrual calculation, but the same vesting principle applies: once the time is granted, it belongs to the employee.
Whichever method applies, the formula has to be clearly spelled out in the handbook or written policy. If the employer cannot show exactly how many hours an employee has accrued, the Labor Commissioner resolves the ambiguity in the employee’s favor by applying principles of equity and fairness.3California Legislative Information. California Labor Code 227.3
Waiting periods for new hires are allowed. An employer can lawfully say either that PTO accrues from day one but cannot be used for 90 days, or that no PTO is earned at all during the first 90 days. The second version leaves nothing to pay out if the employee leaves during probation. The first version does. Paid sick leave is a separate matter and must begin accruing from the first day of employment regardless of what the vacation policy says.
Caps Are Allowed, Forfeiture Is Not
A policy that forces employees to forfeit unused PTO after a certain date is illegal in California. The DLSE treats use-it-or-lose-it as wage theft and refuses to recognize it.1Department of Industrial Relations. Vacation FAQ
Employers can set a reasonable cap on how many PTO hours an employee can bank at any given time. When a worker hits the cap, accrual pauses until they use some of the balance. No previously earned time disappears, so this is not forfeiture.1Department of Industrial Relations. Vacation FAQ
The DLSE requires that any cap be “reasonable” and warns that a cap used as a subterfuge to deny employees vacation will not be enforced. The agency does not publish a specific number. A widely cited industry benchmark sets the cap at roughly 1.5 to 2 times the annual accrual rate. For an employee earning 80 hours per year, a cap between 120 and 160 hours is the range most employment attorneys consider defensible. A cap too close to the annual rate creates the same practical effect as forfeiture.
Whatever cap an employer selects must be applied consistently across comparable employees. Selective caps invite claims of discrimination.
Combined PTO and Sick Leave
California requires at least 40 hours (five days) of paid sick leave per year, with accrual of at least one hour per 30 hours worked and a permissible cap of 80 hours. An employer can also front-load the full 40 hours at the start of the year.4Department of Industrial Relations. California Paid Sick Leave Frequently Asked Questions
Employers who use a single combined PTO bank for vacation and sick leave do not have to provide separate sick leave, but the combined policy must meet every minimum of the sick leave law: the one-hour-per-30 accrual rate, use for any purpose the sick leave statute covers, and carryover of unused hours if using accrual.4Department of Industrial Relations. California Paid Sick Leave Frequently Asked Questions
The combined-bank choice has a real cost. Standalone sick leave does not have to be paid out at termination and can be forfeited when the employee leaves. The moment sick hours sit inside a combined PTO bank, the whole balance is treated as vacation wages and must be paid out at the final rate of pay.
Payout When Employment Ends
Every hour of earned, unused PTO must be paid out when an employee leaves, whether the departure is a firing, layoff, or resignation. Labor Code Section 227.3 prohibits any policy that provides for forfeiture of vested vacation time upon termination.3California Legislative Information. California Labor Code 227.3 The payout is calculated at the employee’s final rate of pay, not the rate at which the hours were originally earned.
Final Paycheck Deadlines
California imposes tight deadlines on final paychecks, and the PTO payout must be included:
- Fired or laid off: all wages, including accrued PTO, are due immediately at the time of discharge.5California Legislative Information. California Labor Code 201
- Quit with at least 72 hours’ notice: final pay is due on the employee’s last day of work.6California Legislative Information. California Labor Code 202
- Quit without 72 hours’ notice: the employer has 72 hours from the resignation to deliver final pay.6California Legislative Information. California Labor Code 202
Waiting Time Penalties
An employer who willfully misses these deadlines owes a waiting time penalty equal to the employee’s daily rate of pay for each day the wages go unpaid, up to a maximum of 30 days.7Department of Industrial Relations. Waiting Time Penalty An employee earning $30 per hour on an eight-hour day has a daily rate of $240. A full 30-day delay produces $7,200 in penalties on top of the PTO balance itself.
Unlimited PTO Policies
A genuinely unlimited PTO policy can escape the termination payout rule, because without a fixed accrual there is no vested balance to pay. The California Court of Appeal in McPherson v. EF Intercultural Foundation acknowledged this, but only if the policy meets specific conditions.8FindLaw. McPherson v EF Intercultural Foundation Inc The court set out four:
- The policy must be written and clearly state that PTO is not additional compensation for work performed, but part of a flexible scheduling arrangement.
- Both the employee and employer must understand the consequences of failing to schedule time off.
- Employees must actually be able to take time off in practice, not just on paper.
- The policy cannot operate as a disguised use-it-or-lose-it scheme, and it cannot leave some employees working far more hours than others in similar roles.
A policy labeled “unlimited” that lacks these specifics, or sits inside a culture that discourages taking time off, can still trigger a payout obligation at termination.
PTO and Overtime
PTO hours do not count toward overtime. Overtime under both federal and California law is based on hours actually worked, not hours paid.9U.S. Department of Labor. Overtime Pay Taking eight hours of PTO on Monday and working 36 hours the rest of the week does not produce 44 compensable hours. The same holds for California’s daily overtime: only hours actually worked count toward the eight-hour daily threshold.
PTO With FMLA and California Paid Family Leave
Federal FMLA leave is unpaid by default. FMLA regulations allow either the employee or the employer to require substitution of accrued paid leave so the employee receives a paycheck during the absence, and the paid leave runs concurrently with FMLA rather than extending it.10eCFR. 29 CFR 825.207
California narrowed that rule for state Paid Family Leave. Under AB 2123, effective January 1, 2025, employers can no longer require employees to use accrued vacation before receiving California Paid Family Leave benefits. The prior rule allowed employers to force workers through up to two weeks of vacation first. Employees can now preserve their PTO balance while collecting state PFL.
When an employee receives other income-replacement benefits such as short-term disability or workers’ compensation, the FMLA substitution rule does not reach them, because that rule applies only to otherwise unpaid leave. An employer generally cannot force PTO usage when another wage-replacement source is already paying out.
Caps and the ADA
An accrual cap or carryover limit may have to bend for an employee with a disability. The EEOC has said reasonable accommodations can include changes to leave policies, including policies that limit the amount of leave employees can take, when an employee with a disability needs additional leave.11U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act An employee with a qualifying disability can request an exception to the standard cap, and the employer must grant it unless doing so creates an undue hardship, even if other employees remain subject to the normal limit.
