The PAGA statute of limitations is one year. It runs from the date of the Labor Code violation you’re suing over, under California Code of Civil Procedure section 340(a), which sets a one-year deadline for any action seeking a statutory penalty when the statute itself is silent on timing.1California Legislative Information. California Code of Civil Procedure 340 – Time of Commencing Actions PAGA is silent, so section 340(a) controls. Miss the year and you generally lose the right to pursue PAGA penalties for that violation.
Where the One-Year Deadline Comes From
PAGA lets employees recover civil penalties on behalf of the state rather than personal damages, and section 340(a) covers exactly that kind of action. The California Court of Appeal put it plainly in Brown v. Ralphs Grocery Co.: “the statute of limitations for PAGA claims is one year.”2FindLaw. Brown v Ralphs Grocery Company
Courts enforce the deadline strictly. Employers routinely move to dismiss claims filed even a day late, and those motions succeed. The clock is not tied to when you hire an attorney or when you first realize a violation happened. It runs from the violation itself.
When the Clock Starts
A PAGA claim accrues on the day the specific Labor Code violation occurs. Shorted overtime on a June 1 paycheck creates a one-year window that closes 365 days later. Each pay period with a violation has its own accrual date and its own separate clock. A missed meal break in January and another in March are two distinct violations, timed independently.
For ongoing violations, this creates a rolling look-back. You can recover penalties only for violations that fell within one year before you filed your LWDA notice. Anything older is excluded from the penalty calculation, even if the same unlawful practice ran for years before that. The filing date on your notice sets how far back your claim reaches. Filing a week earlier or later can add or eliminate an entire pay period’s worth of penalties.
How the LWDA Notice Pauses the Clock
Before suing, you must give written notice to the Labor and Workforce Development Agency and your employer, describing the specific Labor Code violations along with the facts and legal theories supporting them.3California Legislative Information. California Labor Code 2699.3 The one-year statute is tolled while the agency reviews that notice.
The LWDA has 65 calendar days to decide whether to investigate. If it declines or does not respond, you can file suit. If it opens an investigation, it gets 120 additional calendar days to complete the review and decide whether to issue a citation. The clock stays paused throughout.
Practically, filing the LWDA notice early protects the claim in two ways. It preserves the longest possible look-back for penalty calculations, and it leaves breathing room if the administrative process drags. Sitting on a notice while you build the rest of a case is where claims die.
PAGA Deadlines vs. Wage Claim Deadlines
The most costly misconception is treating the PAGA deadline like the deadline for the underlying wage claim. They are not the same. An employee shorted on overtime generally has three years to sue for the unpaid wages under Code of Civil Procedure section 338, and potentially four years if the claim is pursued as an unfair business practice. The PAGA penalty for that same overtime violation expires after one year.1California Legislative Information. California Code of Civil Procedure 340 – Time of Commencing Actions
You can have a live wage claim and a dead PAGA claim over the same paycheck. If both are on the table, the LWDA notice needs to go out first, because it has the shorter fuse.
The 2024 reform’s cure provisions reference a three-year look-back for making employees whole on wages owed, but that figure applies to the cure calculation, not the penalty period.4Labor and Workforce Development Agency. Private Attorneys General Act (PAGA) Frequently Asked Questions The limitations period for PAGA civil penalties remains one year regardless of how far back the underlying wage violations run.
Amended Complaints and Relation Back
If you discover additional violations or need to substitute a new plaintiff after filing, the relation back doctrine can treat an amended complaint as filed on the date of the original suit. That can save claims that would otherwise be time-barred. To qualify, the amended claims have to arise from the same general facts, involve the same type of injury, and stem from the same employer conduct described in the original filing.
The key question is whether the original LWDA notice gave the employer fair notice of the allegations. Courts have applied relation back even where a new plaintiff is substituted in, on the theory that the LWDA is the real party in interest regardless of which employee brings the action. If the amendment reaches into unrelated Labor Code sections the employer had no reason to anticipate, the one-year bar will block it.
Drafting the LWDA notice broadly, describing the employer’s conduct in general terms rather than a single narrow violation, gives amendments more room to relate back. The notice still has to contain enough factual detail to satisfy the statutory requirement of “facts and theories to support the alleged violation.”3California Legislative Information. California Labor Code 2699.3
Standing After Arbitration or Settlement of Your Individual Claim
Employers sometimes try to shut down a PAGA case by resolving the plaintiff’s individual dispute fast. In Adolph v. Uber Technologies, Inc., the California Supreme Court held that an order compelling arbitration of a plaintiff’s individual PAGA claim does not strip them of standing to litigate representative claims on behalf of other employees.5Justia Law. Adolph v Uber Technologies, Inc. Arbitrating or settling the individual piece does not erase the fact that a violation occurred or the plaintiff’s status as an aggrieved employee.
The 2024 reform adds a wrinkle. Under the tighter standing rules, the plaintiff must show they personally experienced the specific violation within the one-year window. If the individual violation is time-barred rather than simply arbitrated or settled, standing collapses for that category of violation on behalf of anyone.
What the 2024 Reform Changed About the Deadline
California overhauled PAGA through AB 2288 and SB 92, effective for actions based on LWDA notices filed on or after June 19, 2024.6California Legislative Information. AB 2288 Bill Text The one-year statute of limitations itself did not change. Several reforms still affect how the deadline plays out.
Standing tightened. A plaintiff must have personally experienced the specific Labor Code violation being sued over, and that violation must have occurred within the one-year period. Representative claims are limited to other employees who suffered violations of the same Labor Code provision the plaintiff did. If the plaintiff’s own violation is time-barred, so is the ability to represent others on that provision.6California Legislative Information. AB 2288 Bill Text
Employer cure and early evaluation processes now sit between the LWDA notice and the courtroom. Small employers can submit a confidential cure proposal to the LWDA; larger employers can request judicial early evaluation. These procedures do not extend the one-year limitations period, but they add steps that need to be built into any litigation timeline.
