You just found out your coworker makes significantly more than you. Same job. Same responsibilities. Same hours. The only obvious difference? Your gender, your race, or your ethnicity.

Maybe you’ve known about this for a while but figured it was too late to do anything. Maybe you left that job two years ago and assumed the window had closed. Here’s the good news: California’s pay equity law changed in 2026, and the new rules give you more time and more power to fight back than ever before.

Senate Bill 642 — the Pay Equity Enforcement Act — took effect on January 1, 2026, and it’s one of the most significant expansions of equal pay protections California has ever passed. If you suspect you’ve been paid less than coworkers doing substantially similar work, this law was written for you.

What Changed Under SB 642 — and Why It Matters

Before 2026, California’s Equal Pay Act already prohibited employers from paying workers less based on sex, race, or ethnicity. But there were practical barriers that made it hard for employees to actually use the law.

The biggest one? Time. Under the old rules, you generally had two years to file a claim — unless you could prove your employer’s violation was “willful,” which bumped it to three years. Proving willfulness added a whole extra legal battle on top of the pay dispute itself.

SB 642 sweeps that problem away. Here’s what’s different now:

The filing window is longer. You now have three years from the last date of the violation to bring a claim — period. You no longer have to prove your employer intentionally underpaid you to get that extra year. Three years is the standard.

The recovery window goes even deeper. This is the part that catches people off guard. Even though you have three years to file, you can recover back pay for up to six years — as long as the pay disparity continued into that window. So if you were underpaid for five years and file within three years of the last underpayment, you could potentially recover wages going back the full five years.

“Wages” now means more than your base salary. Under the old law, pay equity disputes often focused on hourly rates or salary. SB 642 expands the definition of “wages” to include bonuses, overtime pay, stock options, profit-sharing, vacation pay, life insurance, travel reimbursements, and other forms of compensation. If your employer pays you less in any of these categories compared to a coworker doing substantially similar work, that could be an Equal Pay Act violation.

The law now protects all genders. The previous version of the law prohibited paying someone less than an employee of the “opposite sex.” SB 642 updates that language to “another sex” — which means non-binary employees are now explicitly covered.

How to Know If You Have a Pay Equity Claim

Say you find out a coworker doing the same job makes $15,000 more than you per year. You’ve been there longer, you have comparable qualifications, and you can’t figure out any legitimate reason for the gap. That’s exactly the kind of situation the Equal Pay Act was designed to address.

Under California law, your employer can’t pay you less than someone of a different sex, race, or ethnicity who performs “substantially similar work” — unless they can justify the difference with a legitimate factor like seniority, a merit system, a system that measures productivity, or a genuine business reason like education, training, or experience.

The key word is substantially similar. Your title doesn’t have to be identical. Your job duties don’t have to match exactly. If the core work is comparable, the law applies.

And thanks to SB 642’s expanded definition of compensation, the disparity doesn’t have to show up in your base pay. If a coworker gets bigger bonuses, more stock options, or better benefits for doing the same work — and the only explanation is a protected characteristic — that counts too. If you think pay discrimination in California is affecting your paycheck, it’s worth looking into.

If you’re unsure whether your situation qualifies, an employment law attorney in Los Angeles can review the specifics and help you understand your options.

Your Employer Can’t Punish You for Asking Questions

One of the reasons pay gaps persist is simple: people are afraid to ask. Afraid to ask coworkers what they make. Afraid to push back on a lowball offer. Afraid they’ll get fired for raising the issue.

California law directly addresses that fear. It is illegal for your employer to retaliate against you for discussing wages with coworkers, asking about pay practices, or filing an Equal Pay Act complaint. If you get demoted, disciplined, or terminated for exercising these rights, that’s a separate legal violation — and it comes with its own protections.

SB 642 also refined California’s pay transparency rules. The law updated the definition of “pay scale” that employers must include in job postings to mean a good-faith estimate of the salary or hourly wage range they reasonably expect to pay for a position. If your employer isn’t including pay ranges in job listings — or if the posted range doesn’t match what they’re actually paying — that’s worth noting.

If you’ve experienced workplace retaliation for raising pay concerns, that may be a separate claim you can pursue alongside a pay equity case.

What You Can Recover — and Why Acting Matters

If you win an Equal Pay Act claim, the remedies are substantial. You’re entitled to the difference between what you were paid and what you should have been paid, going back up to six years. On top of that, the law provides for an equal amount in liquidated damages — essentially doubling the back pay. Your employer may also be required to cover your attorney’s fees and court costs.

Here’s an example. Imagine you were underpaid by $10,000 per year compared to a coworker of a different sex doing the same job. If that disparity lasted four years and you file within three years of your last paycheck reflecting the gap, you could potentially recover $40,000 in unpaid wages plus $40,000 in liquidated damages — $80,000 total, before attorney’s fees.

That’s real money. And under SB 642, the expanded timeline means far more workers can pursue claims that would have been time-barred under the old rules.

One important note on timing: SB 642 specifies that a cause of action can arise each time you receive a paycheck reflecting an unlawful pay disparity. So even if the original decision to underpay you happened years ago, every paycheck that reflects that decision can restart the clock. This is a critical protection — it means ongoing pay gaps create ongoing violations.

Deadlines for filing vary depending on the specific type of claim and the circumstances of your case, so it’s important to talk to an attorney sooner rather than later. The more time you have, the more options are available to you.

How SB 642 Compares to Federal Law

California’s pay equity protections now significantly exceed federal law. The federal Equal Pay Act provides a two-year filing window — or three years only if the violation was willful. There is no six-year recovery provision at the federal level.

Federal law also uses a narrower definition of “equal work,” while California’s broader “substantially similar work” standard makes it easier for employees to establish a wage gap claim. And the federal law only covers sex-based pay disparities — it doesn’t address race or ethnicity the way California’s law does.

If you work in California, you get the benefit of whichever law offers stronger protection. In almost every case involving pay equity, that’s now California law.

For a deeper understanding of how California’s wage and hour protections apply to your situation, speaking with a local attorney is the fastest way to get clear answers.

Frequently Asked Questions About California’s 2026 Pay Equity Law

How long do I have to file a pay equity claim in California under SB 642?

You have three years from the last date of the violation — and you no longer need to prove your employer did it on purpose to get that full window. On top of that, you may be able to recover back pay going back up to six years if the underpayment continued over that period.

What counts as “wages” under California’s new pay equity law?

Pretty much everything. Salary, overtime, bonuses, stock options, profit-sharing, vacation pay, life insurance, travel reimbursements, even gasoline and cleaning allowances. If there’s a gap in any form of compensation between you and a coworker doing similar work, it could support a claim.

Can I file a pay equity claim if I already left the company?

Yes. You don’t need to still work there. As long as you file within the applicable time limits and the pay gap happened during your employment, you can still pursue a claim.

Does the new law protect non-binary employees?

Yes. SB 642 changed the language from “opposite sex” to “another sex,” so non-binary and gender-nonconforming employees are now explicitly covered.

Can my employer fire me for asking about pay equity?

No. California law makes it illegal to retaliate against you for talking about wages, asking questions about pay practices, or speaking up about pay fairness. If your employer punishes you for exercising those rights, that’s a separate violation — and you may have a retaliation claim on top of a pay equity claim.
