The California Equal Pay Act After SB 642: Labor Code Section 1197.5 as Rewritten for 2026

Current as of July 1, 2026 · Statutory analysis of Labor Code section 1197.5 and section 432.3 as amended by SB 642 (Stats. 2025, ch. 468), effective January 1, 2026, with the operative text quoted from the official code, the governing burden structure under Allen v. Staples, and the Ninth Circuit’s en banc prior-salary rule in Rizo v. Yovino as the federal contrast. Written for practitioners.

In brief. Effective January 1, 2026, SB 642 rewrote California’s Equal Pay Act in four load-bearing places. Section 1197.5 now prohibits paying employees “at wage rates less than the rates paid to employees of another sex” — not the binary “opposite sex” — for substantially similar work. (Lab. Code, § 1197.5, subd. (a).) “Wages” and “wage rates” now expressly “include all forms of pay, including, but not limited to, salary, overtime pay, bonuses, stock, stock options, profit sharing and bonus plans, life insurance, vacation and holiday pay, cleaning or gasoline allowances, hotel accommodations, reimbursement for travel expenses, and benefits.” (Id., subd. (l)(3).) A civil action must be commenced “no later than three years after the last date the cause of action occurs,” with a Ledbetter-style definition under which a cause of action occurs each time a tainted paycheck issues — and the employee may “obtain relief for the entire period of time in which a violation … exists, but not to exceed six years.” (Id., subd. (i)(1)–(3).) And section 432.3 now defines the “pay scale” employers must disclose as “a good faith estimate of the salary or hourly wage range that the employer reasonably expects to pay for the position upon hire.” (Lab. Code, § 432.3, subd. (m)(1).) The retaliation clause of section 1197.5(k), with its 90-day rebuttable presumption, remains the statute’s wrongful-termination hook.

1. From SB 358 to SB 642: the statute’s modern arc

Section 1197.5 dates to 1949, but the modern statute is a product of a decade of successive rewrites. SB 358 (2015) replaced the old “equal work in the same establishment” formula with the current comparator standard — “substantially similar work, when viewed as a composite of skill, effort, and responsibility, and performed under similar working conditions” — tightened the “bona fide factor other than sex” defense, and dropped the same-establishment limitation. Race and ethnicity parity provisions were added shortly after (now subd. (b)). AB 168 (2017) enacted section 432.3’s salary-history ban, and SB 1162 (2022) added the pay-scale disclosure and job-posting requirements now codified at section 432.3(c). The Legislature has continued adjusting the adjacent employer pay-data reporting regime as well, most recently in SB 464 (Stats. 2025, ch. 760, amending Gov. Code, § 12999). SB 642 (Stats. 2025, ch. 468) is the latest and, for litigators, the most consequential installment: it modernized the protected-class language, defined the compensation base, restructured the limitations rules, and pinned down the pay-scale definition. All quotations in this guide are from the section as it reads effective January 1, 2026.

2. The operative prohibition: “another sex” and the four defenses

The core command now reads: “An employer shall not pay any of its employees at wage rates less than the rates paid to employees of another sex for substantially similar work, when viewed as a composite of skill, effort, and responsibility, and performed under similar working conditions.” (§ 1197.5, subd. (a).) The change from “the opposite sex” to “another sex” conforms the statute to California’s recognition of nonbinary gender and eliminates a defense argument that a comparator framework fails where either the plaintiff or the comparator is nonbinary. Subdivision (b) states the parallel prohibition for “employees of another race or ethnicity.”

The employer’s escape routes are unchanged in structure but demanding in application. A differential survives only where the employer demonstrates it is based on “(A) [a] seniority system[,] (B) [a] merit system[,] (C) [a] system that measures earnings by quantity or quality of production[, or] (D) [a] bona fide factor other than sex, such as education, training, or experience” — and the bona fide factor applies “only if the employer demonstrates that the factor is not based on or derived from a sex-based differential in compensation, is job related with respect to the position in question, and is consistent with a business necessity,” itself defeated if “an alternative business practice exists that would serve the same business purpose without producing the wage differential.” (§ 1197.5, subd. (a)(1).) Two overlay requirements sharpen the defense further: “[e]ach factor relied upon is applied reasonably” and the factors “relied upon account for the entire wage differential.” (Id., subd. (a)(2), (3).) And California codified the anti-prior-salary rule directly: “Prior salary shall not justify any disparity in compensation.” (Id., subd. (a)(4).)

The expanded compensation base. SB 642’s definition of “wages” and “wage rates” — “all forms of pay, including, but not limited to, salary, overtime pay, bonuses, stock, stock options, profit sharing and bonus plans, life insurance, vacation and holiday pay, cleaning or gasoline allowances, hotel accommodations, reimbursement for travel expenses, and benefits” (§ 1197.5, subd. (l)(3)) — resolves in the plaintiff’s favor the recurring dispute over whether equity and benefits count. A base-salary match no longer immunizes a differential delivered through option grants, bonus-plan eligibility, or benefits. The definition is expressly confined to this section: “Nothing in this paragraph shall be construed to define ‘wages’ or ‘wage rates’ for purposes of any other section of this code.” (Ibid.)

3. Filing, occurrence, and the six-year relief window

SB 642 rebuilt subdivision (i) around a paycheck-accrual model. A civil action “may be commenced no later than three years after the last date the cause of action occurs” (§ 1197.5, subd. (i)(1)), and a cause of action “occurs” when “(A) [a]n alleged unlawful compensation decision or other practice is adopted[,] (B) [a]n individual becomes subject to an alleged unlawful compensation decision or other practice[, or] (C) [w]hen an individual is affected by application of an alleged unlawful compensation decision or other practice, including each time wages, benefits, or other compensation is paid, resulting in whole or in part from the decision or other practice” (id., subd. (i)(3)). This is the Ledbetter fix in state statutory form: every tainted paycheck restarts the three-year clock, so a discriminatory pay decision made a decade ago remains actionable so long as it continues to depress current compensation.

The remedial window is correspondingly explicit — and capped: “An employee is entitled to obtain relief for the entire period of time in which a violation of subdivision (a) or (b) exists, but not to exceed six years.” (§ 1197.5, subd. (i)(2).) Recovery includes the unpaid wage balance, interest, “and an additional equal amount as liquidated damages,” in a civil action with costs and reasonable attorney’s fees, “notwithstanding any agreement to work for a lesser wage.” (Id., subds. (c), (h).) Subdivision (i)(4) preserves the common-law backstops: “Nothing in this subdivision shall prohibit the application of the doctrine of ‘continuing violation’ or the ‘discovery rule’ to any appropriate claim.”

4. Section 432.3: salary history and the “good faith estimate … upon hire”

Section 432.3 does the prophylactic work. Employers may not “rely on the salary history information of an applicant” in deciding whether to hire or what to pay, and may not “seek salary history information, including compensation and benefits, about an applicant.” (§ 432.3, subds. (a), (b).) Pay-scale transparency obligations attach on request for applicants and current employees, and employers with 15 or more employees must include the pay scale “in any job posting,” including postings placed through third parties. (Id., subd. (c)(1)–(3), (5).)

SB 642 answered the definitional question that had made posting compliance contestable: ” ‘Pay scale’ means a good faith estimate of the salary or hourly wage range that the employer reasonably expects to pay for the position upon hire.” (§ 432.3, subd. (m)(1).) The “good faith estimate … upon hire” formulation cuts both ways. It forecloses the argument that a posted range must encompass every possible future salary in the role — the reference point is hire — but it equally forecloses padding: a range the employer does not “reasonably expect[]” to pay is not a good faith estimate. Enforcement runs through the Labor Commissioner (penalties of $100 to $10,000 per violation, with a first-violation cure provision for postings) and a civil action for injunctive and other relief; a failure to keep required records raises “a rebuttable presumption in favor of the employee’s claim.” (Id., subd. (d).) Voluntarily disclosed salary history may be considered — but never to justify a disparity: “Consistent with Section 1197.5, nothing in this section shall be construed to allow prior salary to justify any disparity in compensation.” (Id., subds. (h)–(k).)

5. Section 1197.5(k): the retaliation clause and the wrongful-termination hook

For the wrongful-termination practitioner, the statute’s most litigated future provision may be subdivision (k). It prohibits an employer from “discharg[ing], or in any manner discriminat[ing] or retaliat[ing] against, any employee by reason of any action taken by the employee to invoke or assist in any manner the enforcement of this section,” and adds a potent evidentiary device: “If an employer engages in any action prohibited by this section within 90 days of the protected activity specified in this section, there shall be a rebuttable presumption in favor of the employee’s claim.” (§ 1197.5, subd. (k)(1).) The same subdivision protects pay transparency among employees — an employer “shall not prohibit an employee from disclosing the employee’s own wages, discussing the wages of others, inquiring about another employee’s wages, or aiding or encouraging any other employee to exercise their rights under this section.” (Ibid.)

The remedy for retaliatory discharge is “reinstatement and reimbursement for lost wages and work benefits caused by the acts of the employer, including interest thereon, as well as appropriate equitable relief” — but note the trap: a subdivision (k) civil action “may be commenced no later than one year after the cause of action occurs.” (§ 1197.5, subd. (k)(2), (3).) The one-year clock is dramatically shorter than the pay claim’s three-year/occurrence regime, and shorter than the two-year period for a companion Tameny discharge tort. An employee terminated after asking about a coworker’s pay, discussing wages, or complaining of a disparity has claims on three different clocks; calendar all of them at intake.

6. Litigating the claim: prima facie case and the employer’s proof burden

The burden structure is settled and plaintiff-friendly. The plaintiff “must establish that, based on gender, the employer pays different wages to employees doing substantially similar work under substantially similar conditions”; the burden then “shifts to the employer to prove the disparity is permitted by one of the EPA’s [four] statutory exceptions.” (Allen v. Staples, Inc. (2022) 84 Cal.App.5th 188, 194, quoting Hall v. County of Los Angeles (2007) 148 Cal.App.4th 318, 323–324.) There is no pretext stage and no intent element on the pay claim itself; the exceptions are the employer’s affirmative burden.

Allen supplies two propositions that do daily work at summary judgment. First, a single comparator suffices: evidence that the plaintiff “was paid $22,000 less in base salary than [a single male comparator] as an [area sales manager] and $48,000 less in base salary than him as an [field sales director] was sufficient to carry her initial burden … and shift to Staples the burden of showing there was no triable issue of fact on one of the four exceptions.” (Allen, supra, 84 Cal.App.5th at pp. 194–195.) Aggregate statistics showing that women on average earned as much or more did not defeat the claim. Second, generalized policy evidence does not carry the employer’s burden: Staples showed “only that, as a general practice, it set salaries based on factors such as seniority, years of experience in a given position, and merit,” but “did not set forth the specific factors on which [the comparator’s] base salary … was premised or the factors on which plaintiff’s base salaries were premised” — so the bona-fide-factors defense failed. (Id. at p. 195.) Allen predates SB 642, but its specificity requirement maps directly onto the codified overlays that each factor be “applied reasonably” and that the factors “account for the entire wage differential.” (§ 1197.5, subd. (a)(2), (3).) After SB 642, the Allen analysis also runs over a wider compensation base: comparator discovery should capture equity grants, bonus-plan participation, and benefits, not base salary alone. (Id., subd. (l)(3).)

Note when reading the older cases that Allen and its predecessors quote the pre-2016 statutory text (“opposite sex,” “equal work,” “same establishment”) — superseded by SB 358 and now SB 642 — while their burden-structure holdings remain good law. (See Allen, supra, 84 Cal.App.5th at pp. 193–194.)

7. The federal contrast: Rizo v. Yovino and prior pay under 29 U.S.C. § 206(d)

California plaintiffs typically plead the federal Equal Pay Act alongside section 1197.5, and the Ninth Circuit’s en banc decision in Rizo v. Yovino (9th Cir. 2020) 950 F.3d 1217 (cert. den. July 2, 2020) aligns the federal claim with California’s codified rule on the decisive question of prior salary. Fresno County had set a math consultant’s starting pay mechanically from her prior salary plus five percent, leaving her tens of thousands of dollars behind male colleagues doing the same work; the county’s only defense was that prior pay was a “factor other than sex” under 29 U.S.C. § 206(d)(1)(iv). The en banc court held it is not: “only job-related factors may serve as affirmative defenses to EPA claims,” and “an employee’s prior pay cannot serve as an affirmative defense to a prima facie showing of an EPA violation.” (Rizo, supra, 950 F.3d at pp. 1219–1220.) “Prior pay — pay received for a different job — is necessarily not a factor related to the job for which an EPA plaintiff must demonstrate unequal pay for equal work.” (Id. at p. 1227.) The court overruled Kouba v. Allstate Insurance Co. (9th Cir. 1982) 691 F.2d 873 and held that prior pay fails as a defense “alone or in combination with other factors.” (Id. at pp. 1229–1230.) It also clarified the federal claim’s structure: strict liability, two steps, “[n]o showing of pretext is required.” (Id. at p. 1223.)

Five of the eleven judges wrote separately: they agreed prior pay alone cannot justify a differential but objected that the majority’s categorical rule — reaching prior pay even “in combination with other factors” — was, in Judge McKeown’s words, “a rule not adopted by any other circuit.” (Rizo, supra, 950 F.3d at p. 1232 (conc. opn. of McKeown, J.).) For California practice the debate is academic: the Legislature resolved it by statute. Section 1197.5(a)(4) and (b)(4) flatly provide that “[p]rior salary shall not justify any disparity in compensation,” and section 432.3 forbids seeking or relying on salary history at hire. The California regime is thus stricter than even Rizo‘s federal rule — Rizo permits employers to consider prior pay in negotiating or setting salaries (while denying it any defensive value, 950 F.3d at pp. 1231–1232), whereas section 432.3 bars the inquiry itself.

8. Practice notes

Reprice the claim under the new definitions. Damages models and comparator discovery should sweep the full subdivision (l)(3) compensation base — equity, bonus-plan terms, insurance, allowances, travel and housing benefits — across the full relief window: up to six years of violation-period recovery, doubled by liquidated damages, plus interest and fees. (§ 1197.5, subds. (c), (h), (i)(2).)

Plead occurrence with the paycheck rule. Identify the compensation decision or practice, then allege its application “each time wages, benefits, or other compensation is paid.” (§ 1197.5, subd. (i)(3)(C).) Preserve continuing-violation and discovery-rule theories in the alternative. (Id., subd. (i)(4).)

Use Allen to frame the summary judgment fight. One well-chosen comparator makes the prima facie case; the employer must then prove — with employee-specific evidence, not policy generalities — factors that are job-related, reasonably applied, and sufficient to explain the entire differential. (Allen, supra, 84 Cal.App.5th at pp. 194–195; § 1197.5, subd. (a)(1)–(3).)

Treat pay-transparency retaliation as a wrongful-termination theory. Wage discussions and pay inquiries are protected by subdivision (k); a discharge within 90 days carries a rebuttable presumption. But the one-year limitations period is unforgiving — file early or pair the claim with theories on longer clocks. (§ 1197.5, subd. (k).)

Audit the posting file in every case. Job postings and pay-scale records are now discoverable admissions: a posted “good faith estimate” that diverges from what comparators were actually paid is powerful evidence on both the pay claim and willfulness, and record-keeping failures raise a statutory presumption. (§ 432.3, subds. (c)(4), (d)(5), (m)(1).)

For employers. SB 642 converts pay-structure hygiene into litigation defense: document the specific, job-related basis for each individual’s compensation at the time it is set (the Allen lesson), reconcile posted ranges with actual offers, and treat any adverse action within 90 days of a pay complaint or wage discussion as presumptively suspect.
