California's Equal Pay Act is the most protective equal pay statute in the country — and it works differently than most people assume. It is not simply part of the Fair Employment and Housing Act. It operates independently under Labor Code §1197.5, has its own deadlines, its own remedies, and its own obligations that apply to nearly every California employer. Employees who discover a pay gap have a private right of action in civil court without going through the CRD first. Employers who haven't audited their pay practices under the current standard are very likely out of compliance.
This guide covers both sides: what employers are legally required to do, and what employees can claim when those obligations aren't met.
Section 1: What the California Equal Pay Act Requires of Employers
The "Substantially Similar Work" Standard (SB 358, 2016)
Before 2016, California's Equal Pay Act required equal pay only between employees doing the same work at the same establishment. SB 358 eliminated both of those limiters. Under current Labor Code §1197.5, employees must receive equal pay for substantially similar work — regardless of job title, department, or location.
What does "substantially similar" mean in practice? Courts and the Labor Commissioner look at three factors:
- Skill — the education, training, and experience required to perform the work
- Effort — the physical and mental exertion required
- Responsibility — the degree of accountability and decision-making authority involved
An employer cannot escape an equal pay claim by giving employees different titles or placing them in different buildings. If the work is substantially similar, the pay must be too. This is the standard courts apply.
What employers must do: Audit your job classifications not by title, but by actual work performed. If two employees are doing work that is substantially similar under the skill/effort/responsibility framework, their pay must be equal — or the differential must be fully justified.
Justifying a Wage Differential — and the Salary History Trap (AB 168)
An employer can lawfully pay employees different wages for substantially similar work, but only if the entire wage differential — not just part of it — is justified by one or more of four permissible factors under §1197.5(a):
- A seniority system
- A merit system
- A production-based compensation system
- A bona fide factor other than sex, race, or ethnicity — such as education, training, or relevant experience — that is job-related and consistent with business necessity
The catch-all fourth factor has a critical limitation: the factor must be reasonable and must apply to all employees. And since AB 168 took effect in 2018, there is one justification employers can no longer use: prior salary history.
AB 168 (codified into §1197.5(a)(3)) prohibits employers from asking job applicants about their prior salary. More importantly, it prohibits employers from relying on prior salary as the sole or default justification for setting a lower wage. Employers who have historically paid women less because they "started from a lower salary history" are now in violation if that prior salary is the primary reason for the gap. Closing a pay disparity by citing a new hire's lower old salary is not a legitimate bona fide factor under California law.
What employers must do: Review your compensation-setting process. If prior salary is in your hiring workflow as a default driver of starting pay, remove it. Document the actual factors — market rate, experience, skills — that justify starting pay for each role.
SB 1162: Pay Transparency in Job Postings and Pay Data Reporting
California's SB 1162 (effective 2023) added two major employer obligations under Labor Code §432.3:
1. Pay scale in all job postings (15+ employees)
If your business has 15 or more employees, you must include the pay scale (the salary or hourly range you reasonably expect to pay for the role) in every job posting — including postings made through third-party job boards. "We'll discuss compensation" or "competitive salary" does not satisfy this requirement.
Penalties for non-compliance run from $100 to $10,000 per violation per posting. The CRD enforces this, and both job applicants and current employees have a private right of action to sue for violations.
2. Pay scale on request for current employees (all covered employers)
Any current employee may request the pay scale for their current position at any time. Employers must provide it within a reasonable period. This right exists even for employees who have been in a role for years.
3. Annual pay data reports to CRD (100+ employees)
Employers with 100 or more employees must submit annual pay data reports to the Civil Rights Department. These reports break down pay by sex, race, and ethnicity across job categories and pay bands. Reports are filed by the second Wednesday in May each year. Missing this deadline exposes employers to civil penalties and CRD enforcement action.
What employers must do: Update all job postings to include pay scales if you have 15+ employees. Build a process for responding to employee pay scale requests. If you have 100+ employees, make sure you're submitting your annual pay data report on time.
Wage Discussion Rights (Labor Code §232 and §232.5)
Employees have the explicit legal right to discuss and disclose their wages to coworkers under Labor Code §232. Employers cannot:
- Prohibit employees from discussing wages
- Require employees to sign policies that ban wage discussions
- Retaliate against employees for disclosing or asking about wages
Labor Code §232.5 adds an additional prohibition: employers cannot maintain any policy that prevents employees from disclosing their wages. A handbook policy that says "employees shall not discuss compensation" is a per se violation.
What employers must do: Review your employee handbook and any confidentiality policies. Remove or revise any language that could be construed as prohibiting wage discussions. Silence on this topic does not create legal protection — if your policies implicitly discourage wage talk, that can be actionable.
Section 2: How Employees Can Use the California Equal Pay Act
Identifying a Potential Violation
You do not need someone in the exact same job title to identify a potential Equal Pay Act violation. Under the substantially similar work standard, you look for comparators based on actual work performed:
- Do you and a coworker with a different title perform tasks requiring the same level of skill, similar physical and mental effort, and comparable accountability?
- Are you and the comparator working under similar conditions (shift, environment, safety risk)?
- Does the pay differential exist along lines of sex, race, or ethnicity?
Same establishment is also not required. A woman at a company's San Diego branch can compare herself to a male employee at the company's San Francisco office if the work is substantially similar.
SB 1162 Pay Data Reports as an Investigative Tool
This is one of the most underused enforcement tools in California. Pay data reports that employers with 100+ employees submit to the CRD are publicly available. Employees can search CRD's public database to review their own employer's reported pay distributions across sex and race/ethnicity categories, broken down by job category.
If your employer's CRD pay data report shows a consistent pattern of women in your job category being paid less than men — even without identifying specific individuals — that is evidence of a systemic pay disparity that can support your claim. This is a practical investigative step that most equal pay guides never mention.
Documentation: What to Gather
Before filing any claim, build your evidentiary record:
- Personnel file — Request it under Labor Code §1198.5. Your employer has 30 days to provide it. It contains your performance reviews, disciplinary records, and any documented compensation decisions.
- Pay scale from the job posting — If your employer has 15+ employees and posted a job listing for your role, the pay scale in that posting is a baseline document. Screenshot and preserve it.
- Pay scale on request — Ask your employer directly for the pay scale for your current role. You're entitled to it. Their response (or refusal) is evidence.
- Wage comparator conversations — Labor Code §232 protects you when you discuss wages with coworkers. If a coworker volunteers their pay, document it: date, what was said, the person's name and role. That note is contemporaneous evidence.
- Performance reviews and metrics — Equal performance plus unequal pay is a core pattern in Equal Pay Act claims. Document your own performance record and, where possible, what you know about comparators'.
The 2-Year Deadline Trap
This is one of the most practical distinctions in California employment law and one that catches employees off guard. Equal Pay Act claims under Labor Code §1197.5(h) carry a 2-year statute of limitations — not 3 years.
FEHA gender discrimination claims have a 3-year deadline. If you have a pay discrimination situation that could be framed both as an Equal Pay Act violation and FEHA sex discrimination, you might assume you have 3 years for all of it. You don't. The Equal Pay Act clock runs faster. If you're approaching 2 years from when you first learned of the pay disparity, file now — don't wait on the theory that the FEHA deadline gives you more time.
Section 3: Filing a Claim Under the Equal Pay Act
CRD Complaint Path
You can file a complaint with the Civil Rights Department (CRD) at calcivilrights.ca.gov. California has a worksharing agreement with the EEOC, so filing with the CRD cross-files with the EEOC automatically — you only need to file once.
The CRD investigates, may attempt mediation, and can issue a right-to-sue notice upon request or at the conclusion of its investigation. CRD enforcement is available for both individual claims and systemic employer violations.
Private Civil Action — No CRD Exhaustion Required
Unlike FEHA claims, which require you to exhaust your administrative remedy by filing with the CRD before you can go to civil court, the Equal Pay Act allows a private civil action in California Superior Court directly — without filing a CRD complaint first. This is a significant procedural advantage. Employees with strong, documented Equal Pay Act claims can go directly to court within the 2-year window without waiting for a CRD investigation to run its course.
Remedies: What You Can Recover
Under Labor Code §1197.5(h), a prevailing employee in an Equal Pay Act claim is entitled to:
- The wage differential — the full amount of the underpayment
- An equal amount as liquidated damages — automatic double recovery; this is not discretionary
- Interest on the unpaid wages
- Attorneys' fees and costs
The liquidated damages provision distinguishes the Equal Pay Act from FEHA gender discrimination. Under FEHA, emotional distress is often the centerpiece of damages. Under the Equal Pay Act, recovery is economic and automatic: if you prove the underpayment, you get the underpayment plus an equal amount in liquidated damages, plus interest, plus fees. This is a powerful incentive for employers to resolve valid claims.

Section 4: Common Employer Mistakes Under the Equal Pay Act
Most Equal Pay Act compliance gaps aren't intentional — they're structural. Here are the patterns that create liability:
1. Still using salary history as the primary pay-setting factor. AB 168 prohibited relying on prior salary history as the sole or default justification for a wage differential in 2018. Employers who have never updated their compensation philosophy since then are almost certainly violating §1197.5(a)(3). If your hiring managers still ask for prior salary or use it as the anchor for offers, that is a compliance gap with direct legal exposure.
2. No pay scale in job postings. SB 1162 has been in effect since 2023. Any employer with 15+ employees posting jobs without pay scales is exposed to $100–$10,000 per violation per posting. Class actions for widespread non-compliance have already been filed in California. This is not a theoretical risk.
3. Job title-based pay structures that have never been "substantially similar" audited. Many employers set pay by title: "a Level 2 Analyst earns X." But if a female Level 2 Analyst and a male Senior Coordinator are doing substantially similar work, title doesn't matter. If your pay structure has never been reviewed through the lens of actual work performed — skill, effort, responsibility — you likely have undiscovered gaps.
4. Handbook policies that are silent or restrictive on wage discussions. The absence of an explicit wage discussion policy is not neutral — if your handbook has any confidentiality language broad enough to cover compensation, you are at risk under Lab. Code §232.5. Employers need an affirmative, compliant policy that makes clear employees may discuss wages.
5. Missing the annual pay data reporting deadline. Employers with 100+ employees must report to CRD by the second Wednesday in May. The first missed filing triggers civil penalties; repeated non-compliance escalates. This is a hard deadline with no informal grace period.
