When a California employer switches from an accrual-based vacation policy to unlimited PTO, the accrued balance you’ve already earned doesn’t disappear. California Labor Code Section 227.3 treats vested vacation as wages, so your employer must either pay it out at your current rate or preserve it as you transition to the new policy.1California Legislative Information. California Labor Code 227.3 What changes is what happens going forward, and whether the new policy is structured well enough to hold up under California law.
What Happens to Your Accrued Balance
Every hour of vacation you earned under the old policy is a vested wage. Your employer cannot adopt a “use it or lose it” rule to zero out the balance before flipping the switch.2California Department of Industrial Relations. DLSE Vacation FAQ Whatever sits in your account has to be honored.
Employers usually pick one of three approaches. The cleanest is a lump-sum payout of the full balance when the new policy takes effect, calculated at your rate of pay on the date the accrual policy ends. Some employers instead give you a window to use the accrued time before the switchover. Others carry the legacy balance alongside the new unlimited policy until you draw it down. What no employer can do is erase the balance. Because California classifies vacation as wages, letting it vanish is the same as withholding pay.
If you get a lump-sum payout, check the math on your pay stub carefully. Every accrued hour should appear at the correct rate. If the number is short, you have the right to challenge it.
The Tax Bite on a Lump-Sum Payout
A cash-out can look smaller than you expect once withholding is applied. The IRS treats a vacation payout made on top of regular wages as supplemental income. For 2026, federal withholding on supplemental wages is 22 percent, rising to 37 percent on amounts above $1 million in a calendar year.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employers Tax Guide California adds its own supplemental withholding on top, and Social Security and Medicare taxes apply as they would to any wages.
The withholding rate isn’t your actual tax rate. You may recover some of it when you file your annual return, depending on total income for the year. But the paycheck containing the payout will land noticeably lighter than a rough gross calculation suggests.
Whether the New Unlimited Policy Is Legally Valid
California doesn’t ban unlimited PTO, but the label alone doesn’t make it real. The central risk is an “illusory” policy: one that promises unlimited leave on paper while making it practically impossible to use. When a court finds a policy illusory, it can rule that vacation was accruing all along, which means the employer owes a payout for every unused day at separation.
The leading California case is McPherson v. EF Intercultural Foundation, Inc.4California Courts. McPherson v EF Intercultural Foundation Inc The employer there called its policy unlimited, but the court found employees were effectively limited to two to six weeks per year through unwritten expectations and scheduling constraints. The court held that an employer “cannot avoid the labor law by leaving the amount of vacation time undefined in its policy while impliedly limiting the time actually available for approval.”
The court set out several requirements for a valid unlimited policy:
- The policy must be communicated in writing, not left to informal understanding.
- It must be framed as a flexible work arrangement, not as deferred compensation that accumulates over time.
- Both the employer’s and the employee’s rights and obligations around requesting, approving, and scheduling time off must be spelled out.
- The employer must actually let people take time off, not build a culture where requests are routinely denied or discouraged.
That last point is where most policies fail in practice. A written document saying “take what you need” means nothing if every request triggers pushback from management, or if an unspoken expectation keeps everyone under a week. Courts look at what actually happens, not what the handbook says.
Why this matters to you: if your new policy meets the McPherson requirements, no vacation vests going forward, and you won’t have a balance to cash out when you leave. If it doesn’t meet them, you may still be accruing vacation in practice, and a court could later order the employer to pay it. No California decision has definitively blessed the no-payout outcome for all unlimited policies. McPherson acknowledged the theory but confined its ruling to the facts in front of it.
Sick Leave and Pay Stub Rules Still Apply
California requires employers to show your available paid sick leave balance on your itemized wage statement or a separate document provided on payday. Under an unlimited policy, employers satisfy this by printing “unlimited” on the pay stub or accompanying document.5California Department of Industrial Relations. California Paid Sick Leave – Frequently Asked Questions
You also still have a statutory right to at least five days or 40 hours of paid sick leave per year, regardless of the PTO label.5California Department of Industrial Relations. California Paid Sick Leave – Frequently Asked Questions An unlimited policy that lets you take time off for the qualifying reasons under the sick leave statute (your own illness, caring for a family member, and similar situations) covers the requirement. If the policy somehow restricts sick-related absences, your employer must still provide the statutory minimum separately.
How the Switch Affects FMLA, CFRA, and Disability Leave
Unlimited PTO introduces a wrinkle most employees don’t consider until they need extended leave. The federal Family and Medical Leave Act and California’s Family Rights Act give eligible employees up to 12 weeks of job-protected leave per year. That leave is traditionally unpaid unless the employee has accrued PTO to cover it. Under an unlimited policy, an argument exists that the 12 weeks become fully paid because you have access to unlimited paid time off.
The policy’s language decides this. Many employers explicitly carve out FMLA, CFRA, workers’ compensation, and ADA-related leave from the unlimited policy, treating those as separate categories with their own rules. If your employer’s policy doesn’t carve them out, you may be entitled to paid protected leave rather than the unpaid leave those statutes contemplate. Read the new policy closely for these exclusions.
For disability accommodations, the ADA requires employers to consider modifying leave policies as a reasonable accommodation for employees with disabilities, beyond whatever any PTO policy provides.6U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act Employers are not required to provide indefinite leave where you cannot specify an expected return date. Unlimited PTO doesn’t change these rules, but it can complicate what counts as “reasonable” when the employer’s own policy already offers flexibility.
Your Rights After the Transition
Once the new policy is running, your protection shifts from safeguarding a banked balance to ensuring actual access to time off. You have the right to request and take vacation consistent with the approval process the policy sets out. If your employer systematically denies reasonable requests or creates an environment where taking leave is implicitly punished, the policy risks being declared illusory under McPherson, and the employer may owe back vacation as wages.4California Courts. McPherson v EF Intercultural Foundation Inc
You cannot be retaliated against for using the policy as intended. An employer who cuts your hours, passes you over for promotion, or takes other adverse action because you took time off is violating basic employment protections.
The biggest practical change comes at separation. Under a traditional accrual policy, California requires payout of all unused vacation at your final rate of pay.1California Legislative Information. California Labor Code 227.3 Under a properly structured unlimited policy, nothing accrues or vests, so there’s no balance to cash out when you quit or get terminated. You gain flexibility during employment and give up the separation payout. That trade-off only holds if the policy actually meets the McPherson standards.
If Your Employer Doesn’t Pay What’s Owed
If the transition is handled badly and your accrued balance isn’t properly paid or preserved, you’re looking at a wage violation. California Labor Code Section 203 imposes waiting time penalties when an employer willfully fails to pay wages due: one day’s pay for every day the payment is late, up to 30 days.7California Legislative Information. California Labor Code 203
You can file a wage claim with the California Division of Labor Standards Enforcement, also known as the Labor Commissioner’s Office. Claims can be filed online, by email, by mail, or in person.8California Department of Industrial Relations. How to File a Wage Claim The combination of unpaid wages plus waiting time penalties gives employers a strong incentive to resolve these disputes rather than litigate them.
