Arizona E-Verify Requirements: Enrollment, Penalties, and Legal Shield

Every employer in Arizona must run each new hire through E-Verify after the person starts work and keep a record of that verification. That is the core of Arizona’s E-Verify requirements under the Legal Arizona Workers Act, which took effect January 1, 2008, and ties compliance directly to your business licenses.¹ Skip it and you lose the strongest legal defense Arizona offers; hire an unauthorized worker and you can lose the right to operate.

Who Has to Use E-Verify

The short answer is everyone. Arizona Revised Statutes 23-214 requires every employer to verify each new hire through E-Verify and retain the record for the length of employment or at least three years, whichever is longer.² Private companies, nonprofits, government agencies, self-employed people who hire others. There is no small-business carve-out, no industry exemption, and no minimum headcount.

Two groups carry extra obligations. Government contractors: under ARS 41-4401, no state or local government entity can award a contract to a contractor or subcontractor that fails to comply with E-Verify, and every contract must include a warranty of compliance with federal immigration law.³ Employers receiving state or local economic development incentives must prove enrollment before receiving the money and must repay the full incentive within 30 days if they later fall out of compliance.² Federal contractors whose contracts contain the FAR E-Verify clause also have to verify existing employees assigned to the contract, not only new hires, with enrollment required within 30 days of the contract award.⁴

Enrolling and What You Sign

Enrollment happens on the E-Verify website. You will need your legal business name, EIN, and primary physical address.⁵ The system walks you through questions about your business and generates a Memorandum of Understanding between your company and the Department of Homeland Security. Signing the MOU is what formalizes participation.

The MOU lays out obligations that shape everything you do afterward. You have to verify all new hires, not selected ones. You cannot check anyone before they are hired. Every case must be created within three business days of the employee’s start date. You must display E-Verify participation and Right to Work notices where prospective employees can see them. You must comply with Title VII and federal immigration anti-discrimination rules, meaning no differential treatment based on national origin or citizenship during verification. And when an employee presents a permanent resident card, employment authorization document, or U.S. passport for the I-9, you must photocopy the document and keep it with the form.⁶

After enrollment you designate at least one administrator, and every person who will create cases has to complete an online tutorial before touching the system.⁶

Verifying a New Hire

The process starts with Form I-9. Section 2 has to be completed within three business days of the employee’s first day of work for pay. Start Monday, Section 2 done by Thursday.⁷ The employee presents documents proving identity and work authorization, and you examine them for authenticity.

Once Section 2 is done, you enter the I-9 information into E-Verify. The system cross-references records with DHS and the Social Security Administration and usually returns a confirmation within seconds. When it cannot confirm eligibility, it issues a tentative nonconfirmation, called a mismatch.

When You Get a Mismatch

The mismatch process runs on tight deadlines. You have 10 federal working days from the date E-Verify issues the mismatch to notify the employee and complete the referral steps.⁸ The employee has 10 federal working days from the issuance date to say whether they intend to contest, and if they choose to contest they must contact DHS or visit an SSA office within eight federal working days after the referral.⁹

During this whole window, you cannot fire the employee or take adverse action because of the mismatch. If the employee doesn’t respond within the 10-day window, or if the mismatch becomes a final nonconfirmation after their attempt to resolve it, you close the case in E-Verify and terminate employment.¹⁰

Records You Have to Keep

Two retention rules apply at once. Arizona under ARS 23-214 requires E-Verify records for the length of employment or at least three years, whichever is longer.² Federal law requires the I-9 for three years after the hire date or one year after employment ends, whichever is later.¹¹ The safest approach is to keep the I-9 and the E-Verify record together for whichever period runs longer.

The MOU also requires you to record the E-Verify case verification number on the I-9 or print the case result and attach it to the form.⁶ Hold onto documentation of any mismatch case and its outcome. If an investigator arrives, organized files with case numbers, referral notices, and resolutions are the fastest way to show compliance.

The Legal Shield You Earn by Complying

Compliance is not just about avoiding punishment. E-Verify participation gives Arizona employers a rebuttable presumption that they did not knowingly or intentionally hire an unauthorized worker. If a complaint comes in and you can show the employee was verified through E-Verify, the burden shifts to the government to prove you knew the worker was unauthorized despite the verification.¹² Most investigations die at that step.

Arizona law also provides a separate affirmative defense for employers who can show good-faith compliance with federal I-9 requirements.¹³ An employer that skips E-Verify walks into any investigation without either shield.

Enrollment also opens the door to the alternative procedure for examining I-9 documents remotely. Employers enrolled in E-Verify and in good standing can examine document copies over a live video call rather than requiring in-person presentation.¹⁴ You have to be enrolled at every hiring site where you use it, apply it consistently at each site, allow employees to opt for in-person review, and retain clear copies of both sides of any documents examined this way.

What Happens If You Don’t Comply

Arizona enforces through complaints, not random audits. Anyone can file a complaint alleging an employer knowingly or intentionally hired an unauthorized worker. Complaints based solely on race, color, or national origin are prohibited, and knowingly filing a false complaint is a class 3 misdemeanor.¹² The Attorney General or the county attorney where the worker was employed investigates, and no state or local official independently decides whether a worker is authorized. Status is verified through the federal government.

Knowingly Hiring Unauthorized Workers

A first violation under ARS 23-212 requires the court to order termination of all unauthorized employees, place the business location on three years of probation, and require quarterly reports listing every new hire at that location during the probation period. You also file a sworn affidavit within three business days confirming you have fired all unauthorized workers and will not hire more. Fail to file that affidavit and the court orders suspension of all business licenses specific to the location until you comply.¹²

A second knowing violation results in permanent revocation of all business licenses at the offending location. If you don’t hold a location-specific license, revocation applies at your primary place of business. Reinstatement is not available.¹²

Intentionally Hiring Unauthorized Workers

Penalties under ARS 23-212.01 are harsher. A first intentional violation can result in immediate license suspension, and a second violation triggers mandatory permanent revocation.¹³

Federal Fines Run Alongside

Immigration and Customs Enforcement conducts its own I-9 inspections, separate from Arizona’s complaint process. An audit begins with a Notice of Inspection, and employers get at least three business days to produce the requested I-9 forms.¹⁵ Federal fines run per worker. The base statutory range for a first hiring offense is $250 to $2,000 per worker, rising to $3,000 to $10,000 per worker for employers with multiple prior violations, with those base figures adjusted for inflation each year. I-9 paperwork violations alone carry 2026 penalties of $288 to $2,861 per form. A pattern or practice of hiring unauthorized workers can also bring criminal prosecution with fines up to $3,000 per worker and up to six months of imprisonment.¹⁶

What E-Verify Is Not For

E-Verify is not a screening tool. You cannot run a check on anyone before they’ve been hired and completed Section 1 of the I-9, and you cannot selectively verify some employees but not others. Running checks based on appearance, accent, or national origin violates the MOU and federal anti-discrimination law.¹⁷ The system is built to catch employers who deliberately circumvent immigration law, not to enable profiling of workers.
