Is E-Verify Required in California for Employers?

E-Verify is not required in California for most private employers, and state law actively limits how the system can be used. California prohibits state and local governments from mandating E-Verify for private businesses or making enrollment a condition of a contract or business license. The main exception is federal contractors, who must use E-Verify under federal rules that override the state’s position. Employers who do participate, whether by choice or by federal mandate, face civil penalties of up to $10,000 per violation under California Labor Code Section 2814 if they misuse the system.¹

Who Actually Has to Use E-Verify in California

At the federal level, E-Verify is voluntary for employers who are not federal contractors. California layers an additional restriction on top: the state, cities, counties, and special districts cannot require private employers to enroll, and cannot condition a government contract or a business license on E-Verify participation.

Federal contractors are the group that cannot opt out. A presidential executive order and the Federal Acquisition Regulation require many federal contractors to verify the employment eligibility of workers on covered contracts.² Under FAR clause 52.222-54, a newly awarded contractor that is not yet enrolled must sign up within 30 calendar days of the contract award, begin verifying all new hires within 90 days of enrollment, and verify existing employees assigned to the contract within 90 days of enrollment or 30 days of the assignment, whichever comes later.³

Some California employers enroll voluntarily. Common reasons include operating in states where E-Verify is required and wanting a good-faith defense against knowingly-hiring allegations. Voluntary participation is legal, but it activates every compliance rule discussed below. You cannot pick and choose which new hires go through the system without inviting a discrimination claim.

What California Law Prohibits

Labor Code Section 2814 sets hard limits on when E-Verify can be used. Unless federal law specifically requires it, an employer may not run an E-Verify check on an existing employee or on a job applicant who has not yet received a formal offer of employment.¹ Each unauthorized check is a separate violation carrying a civil penalty of up to $10,000.

The statute targets employers who use E-Verify as a pre-offer screening tool or as a way to pressure current workers. Its stated purpose is to prevent employment discrimination, not to interfere with verification of a person who has actually been offered a job.¹

Labor Code Section 1019.2 separately prohibits reverifying a current employee’s work authorization at a time or in a manner not required by federal law, with its own civil penalty of up to $10,000.⁴ You cannot re-run E-Verify or demand fresh I-9 documentation from a worker whose authorization documents have not expired, even if you suspect a problem.

Labor Code Section 1019.1 targets document abuse. Employers cannot request more or different work authorization documents than federal law requires, refuse to accept documents that reasonably appear genuine, or reject documents based on the specific immigration status tied to the authorization.⁴ Each violation is a separate $10,000 exposure. In practical terms, you cannot insist that a non-citizen produce a green card or an employment authorization document when the worker has already presented a valid combination of documents from the I-9 list. Federal law reaches the same conduct through 8 U.S.C. Section 1324b, which treats document abuse as an unfair immigration-related employment practice.⁵

What Enrolled Employers Must Do

Create Cases Within Three Business Days

You must create an E-Verify case for each new hire within three business days after the employee starts working for pay.⁶ The case draws from the completed Form I-9, and E-Verify compares that data against Social Security Administration and Department of Homeland Security records.⁷ Batch onboarding is where employers most often blow the deadline.

Display Both Required Posters

Every participating employer must display the E-Verify Participation Poster and the Right to Work Poster in both English and Spanish, positioned where prospective employees and current workers going through the system can see them. Remote workers should receive the posters digitally or with their application materials.⁸ The posters cannot be altered or purchased from a third-party vendor.

Keep the Case Number With the I-9

Record each E-Verify case verification number on the corresponding Form I-9, or attach a copy of the case details page.⁹ USCIS eventually disposes of records more than 10 years old on its side, so your own file may be the only proof of compliance in an audit.

Apply the System Consistently

You cannot verify only workers who look or sound foreign, or run checks selectively based on national origin or perceived citizenship. The Department of Justice’s Immigrant and Employee Rights Section investigates complaints about discriminatory E-Verify practices.¹⁰

Handling a Mismatch Without Triggering Liability

A Tentative Nonconfirmation, now called a “mismatch,” means the information entered in E-Verify did not match federal records. It does not mean the employee is unauthorized to work. Data entry errors, name changes, and outdated Social Security records are common causes, and this is where employers most often stumble into liability.

When a mismatch comes back, notify the employee privately and provide the Further Action Notice as soon as practicable. California law also requires the employer to furnish any notification from SSA or DHS that contains information specific to the employee’s case.¹ The employer has 10 federal government working days from when E-Verify issued the mismatch to complete notification and referral.¹¹

During that period, you may not terminate, suspend, delay training, withhold pay, reduce pay, or take any other adverse action against the employee because of the mismatch.¹¹ The employee keeps working on the same terms while the case is resolved. Suspending someone over a mismatch creates a federal E-Verify violation and a California discrimination exposure at the same time.

The employee has eight federal government working days after the referral to begin resolving the mismatch by contacting SSA or DHS. If the mismatch becomes a Final Nonconfirmation after the employee contests and loses, the employer may terminate. If the employee chooses not to contest, or does not respond within the 10-day window, the employer can close the case and terminate without civil or criminal liability.¹¹

Penalties on Both Tracks

An employer who mishandles E-Verify or I-9 can face state and federal penalties for the same conduct.

On the California side, Labor Code Section 2814 carries up to $10,000 per unauthorized use of the system on a current employee or pre-offer applicant.¹ The California Division of Labor Standards Enforcement accepts complaints. Sections 1019.1 (document abuse) and 1019.2 (unauthorized reverification) carry the same $10,000-per-violation ceiling, and the penalties stack: an employer who improperly reverifies through E-Verify and simultaneously demands extra documents could face $10,000 under each section for the same incident.⁴ Affected employees can also sue, adding lost wages, emotional distress damages, and attorney fees.

Federal I-9 penalties are adjusted for inflation. The amounts in effect as of January 2, 2025 through 2026 are:

Paperwork violations: $288 to $2,861 per Form I-9 for substantive errors or uncorrected technical mistakes.
Knowingly hiring unauthorized workers, first offense: $716 to $5,724 per worker.
Second offense: $5,724 to $14,308 per worker.
Third or subsequent offense: $8,586 to $28,619 per worker.¹²

Federal anti-discrimination penalties for document abuse under 8 U.S.C. Section 1324b run from $100 to $1,000 per individual for a first offense, climbing to $3,000 to $10,000 per individual after multiple orders.⁵¹³¹⁴

What Could Change This

The Legal Workforce Act (H.R. 251) was introduced in the 119th Congress in January 2025. If passed, it would make E-Verify mandatory for all U.S. employers on a phased schedule: six months for employers with 10,000 or more workers, 12 months for those with 500 to 9,999 workers, 18 months for employers with 20 to 499 workers, and 24 months for businesses with fewer than 20. Agricultural employers would get 30 months.¹⁵ The bill was referred to committee and had not advanced further as of early 2026. If it passes, California’s restrictions on mandatory E-Verify would be overridden by federal law for all employers, not just federal contractors.
