California Equal Pay Act: Coverage, Claims, and Remedies

The California Equal Pay Act, codified at Labor Code Section 1197.5, prohibits employers from paying you less than a coworker of a different sex, race, or ethnicity when you both perform substantially similar work. If your employer can’t fully explain the gap through seniority, merit, a production-based pay system, or a bona fide job-related factor, you can recover the shortfall, an equal amount in liquidated damages, interest, and attorney fees.¹

Who and What Work Is Covered

The statute protects every employee in California, in every industry and at every job level, against wage discrimination based on sex, race, or ethnicity. Amendments effective in 2016 added race and ethnicity to what had been a sex-only law.¹

The comparison standard is “substantially similar work,” judged by three factors taken together: the skill the job requires, the effort involved, and the level of responsibility. Working conditions also come into the analysis.¹ What counts is what you actually do during the workday. Job titles and internal classifications don’t control. Two employees with different titles can still be doing substantially similar work if their real duties, required training, and daily accountability line up.

Coworkers at Other Locations Count

You don’t have to find your comparison coworker at the same office or facility. California eliminated the old “same establishment” requirement, so you can compare your pay to someone doing substantially similar work at any of your employer’s California locations.² This matters when employers concentrate higher-paid workers at certain sites and lower-paid workers at others along demographic lines.

When a Pay Difference Is Legal

Not every gap violates the law. An employer can defend a wage difference between substantially similar employees by proving it is based entirely on one or more of the following:

A seniority system that rewards longer tenure.
A merit system that ties pay to documented performance evaluation.
A production-based system measuring earnings by quantity or quality, such as commission or piece rate.
A bona fide job-related factor such as education, training, or experience, applied consistent with a business necessity.

The employer carries the full burden here, and the factors it relies on must account for the entire wage differential. A partial explanation isn’t a defense. If your employer can justify 70% of the gap and not the remaining 30%, the defense fails.¹ That “entire differential” requirement is where most employer defenses collapse.

Prior Salary Doesn’t Justify Paying You Less

California law expressly bars employers from using a worker’s prior salary to justify paying that worker less than a coworker for substantially similar work. An employer may consider a current employee’s existing salary in a compensation decision, but only if any resulting pay difference is fully explained by one of the legitimate factors above.¹

Tools for Discovering a Pay Gap

You can’t challenge a gap you can’t see. California gives you several ways to find out what colleagues and prospective employers pay.

You Can Discuss and Ask About Wages

Employers cannot forbid you from talking about your own pay, asking about coworkers’ pay, or encouraging others to exercise their equal pay rights. Retaliation against you for any of these activities is unlawful, and the remedies can include damages and reinstatement.¹ The law protects your right to ask and discuss; it does not require any individual coworker to disclose what they earn.

Employers Can’t Ask About Your Salary History

Under Labor Code Section 432.3, employers cannot ask job applicants about previous salary or benefits, whether directly or through a third party such as a recruiter.³

Pay Scales in Postings and on Request

Employers with 15 or more employees must include the pay scale in every job posting, including postings placed through third-party job boards or recruiters. Pay scale means the salary or hourly wage range the employer reasonably expects to pay.⁴ Any employer, regardless of size, must give a pay scale to a current employee who asks about their own position, and to an applicant who asks about the role they’re applying for.³ A written request creates a paper trail worth keeping.

How to File a Claim

You have two paths: an administrative complaint with the Labor Commissioner’s Office or a lawsuit in California Superior Court. You don’t have to try the administrative route before going to court.⁵

The Labor Commissioner Route

The Division of Labor Standards Enforcement handles administrative claims. Claim forms are available on the agency’s website and can be filed online or by mail.⁶ After you file, the process typically includes a conference where you and your employer each present evidence to a hearing officer. This path is generally faster and cheaper because you don’t need an attorney, though counsel can still help in complex cases.

Filing in Superior Court

The alternative is a civil lawsuit. As of 2026, the initial filing fee for an unlimited civil case (claims over $35,000) is $435, with small variations in Riverside, San Bernardino, and San Francisco counties due to local surcharges.⁷ Court makes more sense when the pay gap is large, the documentation is strong, and you want the broader remedies a judge can order.

How Long You Have to File

You generally have two years from the date of the violation, or three years if the violation was willful.⁵ SB 642, taking effect in 2026, extends the standard period to three years from the last date the violation occurred. Because each paycheck reflecting a discriminatory wage is treated as a separate violation, the clock effectively restarts with every paycheck.

Building the Record

Before filing either way, gather your pay stubs, written job description, performance reviews, emails discussing your duties, and any written communications about compensation decisions. The stronger your documentation of what you actually do compared to a higher-paid colleague, the harder it becomes for your employer to argue the work isn’t substantially similar. California requires employers to keep wage, wage rate, and job classification records for at least three years, so the underlying data should exist on your employer’s side even if you don’t currently have access to it. An employer that failed to keep those records is in a weaker position defending a disparity claim.¹

What You Can Recover

A prevailing employee can recover the full difference between what they were paid and what they should have earned, plus interest, plus liquidated damages equal to the underpayment. In practical terms, the underpayment doubles.¹

A prevailing plaintiff in court also recovers reasonable attorney fees and costs. That fee-shifting provision is why many employment attorneys will take an equal pay case on contingency, and it removes the money question that often keeps workers from filing at all.

How This Compares to Federal Law

The federal Equal Pay Act of 1963 also prohibits sex-based wage discrimination, but California’s statute is broader in ways that can matter to your case. Federal law covers only sex; California adds race and ethnicity. Federal law compares “equal work” within the same establishment; California uses the more flexible “substantially similar work” standard and allows cross-location comparisons.⁸

Under federal law, an employer can reduce or eliminate liquidated damages by showing it acted in good faith with reasonable grounds to believe it wasn’t violating the law.⁹ California has no equivalent good-faith escape. Once a violation is proven, liquidated damages follow automatically. If your situation involves a sex-based gap, you can file under both state and federal law at once; neither requires you to exhaust the other first.
