Can a Prospective Employer Verify Previous Salary in California?

No. In California, a prospective employer generally cannot verify your previous salary. Labor Code Section 432.3 bars employers from asking about your pay history, from seeking it from anyone else, and from relying on it to decide whether to hire you or what to offer you.¹ Two narrow situations change that answer: pay you volunteer on your own, and pay that is already a public record.

What the Law Blocks an Employer From Doing

The ban is written broadly. An employer cannot ask you about your salary history. It cannot ask anyone else about it. And it cannot use the information, even if the information arrives without being asked.¹

“Salary history” is not just your base wage. It covers every form of compensation and benefit tied to a past job: bonuses, commissions, equity, health coverage, retirement contributions, and other financial perks.² The prohibition reaches every employer in the state, private and public.

If the employer stumbles onto your old salary another way — a mutual contact, a news story, something you posted online — the law still prevents them from factoring it into the hiring decision or the offer.¹

Background Checks, W-2s, and Recruiters

Employers cannot sidestep the ban by paying someone else to do the asking. Recruiters, headhunters, staffing agencies, and background check companies are all covered.¹

Because the ban covers every form of seeking salary history, that includes asking for documents that would reveal it. A request to produce W-2s, pay stubs, or tax returns to “confirm” prior compensation is a request for salary history. A standard employment verification can confirm your job titles, dates of employment, and general responsibilities. It cannot cross into pay.

If a background check authorization form asks you to let a third party contact former employers about your compensation rather than simply confirming when you worked there and what you did, that is a signal the process is reaching further than California allows.

If You Volunteer the Number

You can bring up your past pay yourself. If you disclose salary history voluntarily and without prompting, the employer may consider what you shared when setting your offer.² Once you do, the employer is also allowed to verify the specific figures you gave — for example, by calling the former employer to confirm the numbers you cited. The verification cannot be used as an opening to ask broader questions about your pay history.¹

The disclosure has to be genuinely unprompted. A recruiter who says the team “usually finds it helpful” to know your current salary is prompting you. An application field labeled “current compensation” is prompting you, even if nothing on the page says you have to fill it in. The initial move has to come from you, not from a leading question or a suggestive blank.

Volunteering a number also does not give the employer unlimited freedom with it. Under the California Equal Pay Act, prior salary alone cannot justify paying you less than a coworker of a different sex, race, or ethnicity who performs substantially similar work.²

The Public Records Exception

The ban does not reach compensation that is already public. If your past pay is available under the California Public Records Act or the federal Freedom of Information Act, an employer may look it up and consider it.² In practice, this mostly affects people who have worked for government agencies, public universities, or other taxpayer-funded employers, where employee pay is disclosed by law.

The exception is bounded by what is actually in the public record. If you spent five years at a public employer and then three in the private sector, the employer can access the public-sector pay figures but cannot turn that lookup into questions about your private-sector earnings.

What You Can Ask the Employer For

While employers are blocked from reaching into your past, they owe you forward-looking transparency. If you are applying for a job, you can make a reasonable request for the pay scale for the position, and the employer must provide it. The pay scale is a good-faith estimate of the salary or hourly range the employer reasonably expects to pay.¹ Current employees have the same right for their current role.³

Employers with 15 or more employees have an added duty: they must include the pay scale directly in every job posting, including postings placed through third-party job boards or recruiters.³

If an Employer Crosses the Line

You have two ways to act on a violation, and you do not have to choose one before the other.

File a written complaint with the Labor Commissioner within one year of learning about the violation. The Commissioner investigates and, on finding a violation, may impose a civil penalty of $100 to $10,000 per violation.¹
File a civil lawsuit seeking an injunction and any other relief the court considers appropriate. You do not have to go through the administrative process first.³

The one-year window runs from when you learned about the violation, not necessarily when it happened. If you discover months after the fact that an employer pulled or used your salary history, the clock starts on the day you found out.
