California Extended the Equal Pay Deadline. Here's What Changed for Your Business

If you run a business in California, the California Equal Pay Act statute of limitations changed on January 1, 2026, and it now works against employers in ways the old law didn't. Senate Bill 642 replaced a two-tier filing deadline with a flat three-year window that applies to every claim, plus a six-year reach into your payroll history once a claim is filed. 

Read what changed, how the new timeline actually works, and what to check in your pay practices before it becomes a problem.

Key Takeaways

• SB 642 replaced the old 2-year/3-year willful distinction with a flat 3-year filing deadline for all Equal Pay Act claims, effective January 1, 2026.

• Employees may recover up to six years of lost wages if a timely Equal Pay Act claim is established under SB 642.

• Each paycheck that reflects a pay disparity counts as a new violation under the continuing violation framework, thereby extending the period during which a disparity remains actionable.

• "Wages" now includes bonuses, stock, profit-sharing, and benefits, not just salary or hourly pay.

• "Sex" now means "another sex," explicitly extending equal pay comparisons to nonbinary employees.

• Conducting a pay equity audit through legal counsel is generally the best way to maximize attorney-client privilege while evaluating potential Equal Pay Act exposure.

What SB 642 Actually Changed

Before SB 642, the California Equal Pay Act, codified at Labor Code §1197.5, gave employees two years to file a claim for a non-willful violation, or three years if the violation was willful. SB 642 eliminated that distinction.

The statute now runs "three years after the last date the cause of action occurs," and the law spells out what counts as a new occurrence. A cause of action arises each time:

1. an unlawful pay practice is adopted 

2. an employee becomes subject to it, or

3. an employee is affected by it, including every paycheck that reflects the disparity.

That third trigger is what makes the three-year clock functionally longer than it looks.

How the Three-Year Window and Six-Year Lookback Work Together

These are two different numbers doing two different jobs, and conflating them is the most common mistake we see:

1. The three-year window governs whether an employee can bring a claim at all. Because each paycheck reflecting a pay disparity counts as a new violation, an employee is rarely "too late" as long as the disparity is ongoing.

2. The six-year lookback governs how far back damages can be calculated once that claim is filed. Depending on the facts and the continuing nature of the alleged disparity, damages may reach back as far as six years once a timely claim is established.

In practical terms: a pay decision made today doesn't age out of exposure after two or three years anymore. As long as the disparity continues, the clock effectively resets with every pay period, and the damages window trails six years behind whenever a claim lands.

"Wages" and "Sex" Now Mean More Than You'd Assume

Two definitional changes expand who's covered and what's on the table in a claim, and both apply specifically to §1197.5, not the rest of the Labor Code.

Wages now include: salary, overtime pay, bonuses, stock and stock options, profit-sharing and bonus plans, life insurance, vacation and holiday pay, cleaning or gas allowances, hotel accommodations, and travel expense reimbursement. If your comp structure leans on equity grants, signing bonuses, or perks to close a gap in base pay, that gap is no longer invisible to a claim. Total compensation is now what gets compared.

Sex now means "another sex," replacing the old "opposite sex" language. This explicitly extends equal pay protections to nonbinary employees, meaning pay comparisons can now be made across any combination of genders, not just male-to-female.

Separately, SB 642 also tightened the pay transparency side of the law: job postings now require a "good faith estimate" of what you'd actually pay a new hire on day one. If your postings still show a broad catch-all range, that's worth revisiting during this review. It's enforced under the same statute.

Why This Raises Your Exposure

Run an illustrated calculation on a single employee: 

A $20,000 annual pay gap, once six years of back pay are factored in, amounts to $120,000 in potential exposure before liquidated damages, attorneys' fees, or civil penalties are added. For a role with more than one affected employee, that number scales fast, and equal pay claims frequently arrive bundled with a parallel FEHA discrimination claim, since both often stem from the same underlying facts.

That overlap matters for how you defend the case. 

If you're unfamiliar with how FEHA claims work alongside a wage claim like this, our guide on what FEHA is and what it covers is worth reading in tandem. The two statutes are often litigated together, so treating them as separate problems can leave gaps in your defense.

The records that decide these cases are the same records a plaintiff's attorney will request first. Incomplete or inconsistent versions of any of them make it much harder to prove a defensible pay gap after the fact.

What HR Professionals Are Discussing on Public Forums

Pay equity issues rarely begin with a lawsuit. More often, they begin when HR teams realize they cannot easily explain why employees performing substantially similar work are paid differently.

1) In one discussion on Reddit's HR community, an HR/payroll professional raised concerns after discovering internal compensation differences.

Rather than assuming an Equal Pay Act violation, experienced HR practitioners emphasized the importance of documenting legitimate compensation factors, including experience, job responsibilities, seniority, merit systems, and objective business reasons, before any challenge arises. Employers should have clear compensation structures instead of relying solely on individual salary negotiations.

2) Another recent California discussion centered on an employer refusing to provide an employee with the pay scale for their position.

While an employee wrote the post, the discussion serves as a reminder for California employers that pay transparency obligations and compensation documentation are increasingly becoming part of Equal Pay Act disputes. Employers that cannot readily produce compensation policies, pay ranges, and objective reasons for wage differences may find themselves defending multiple Labor Code claims simultaneously.
