What Is IRCA? Employer Requirements and Penalties

The Immigration Reform and Control Act of 1986 sets the employer requirements and penalties that govern every hire in the United States: you must verify each new employee’s identity and permission to work using Form I-9, keep the paperwork, avoid discriminating against workers based on citizenship or national origin, and face civil fines (or, in serious cases, criminal charges) if you fall short. The rules apply to every employer, from a single-location restaurant to a national contractor, and they apply to every person hired after November 6, 1986, regardless of citizenship.¹

Form I-9 Is the Core Requirement

Form I-9, “Employment Eligibility Verification,” is the document that carries the whole compliance regime. The employee fills out Section 1 no later than their first day of work, attesting under penalty of perjury to their citizenship or immigration status. You complete Section 2 within three business days of the hire date, recording which documents the employee showed you and confirming they reasonably appear genuine.²

Your role is narrow. Examine original documents, decide whether they reasonably look genuine and relate to the person in front of you, and record them. You are not asked to make an independent judgment about someone’s immigration status, and you cannot demand more than the form calls for.

Who Can Complete Section 2

You do not have to complete Section 2 personally. Anyone can serve as your “authorized representative,” including an HR officer, a notary public, or a contracted agent, and USCIS does not require a formal agreement. The trade-off is that you remain fully liable for whatever mistakes the representative makes.³ A notary acting in this role is functioning as an authorized representative only and should not affix a notary seal. Employees cannot serve as their own authorized representative.

Which Documents You Must Accept

The I-9 divides acceptable documents into three lists. List A proves both identity and work authorization at once. List B proves only identity. List C proves only work authorization. The employee satisfies the requirement with one List A document, or one List B document combined with one List C document.

Common List A documents include the U.S. passport or passport card, the Permanent Resident Card (Form I-551), a foreign passport with a temporary I-551 stamp, and the Employment Authorization Document (Form I-766). A state driver’s license is a typical List B choice; an unrestricted Social Security card or U.S. birth certificate is a typical List C choice.

The employee chooses which documents to present. If someone offers a valid driver’s license and an unrestricted Social Security card, you cannot insist on a passport or green card instead. Demanding specific documents, or requiring more than the form calls for, is “document abuse” and creates its own liability under IRCA’s anti-discrimination provisions.

Receipts on the First Day

When an employee cannot present a finished document on day one, regulations let them show a receipt. Three types qualify: a receipt for a replacement of a lost, stolen, or damaged document; the departure portion of Form I-94 with an unexpired refugee admission stamp; and the arrival portion of Form I-94 with a temporary I-551 stamp and photograph.⁴ A replacement-document receipt buys 90 days from the hire date; after that, the actual document must be produced. You cannot accept a second receipt to extend that window.

Reverifying Workers Whose Authorization Expires

Some employees hold work authorization that carries an expiration date. As that date approaches, you must reverify by completing Supplement B of the Form I-9 no later than the day authorization expires.⁵ The employee shows a new document proving continued authorization, and you record it. Identity documents do not need to be checked again. Missing a reverification deadline exposes you to the same penalties as never completing an I-9 in the first place.

E-Verify and Remote Document Inspection

E-Verify is an internet-based system that checks Form I-9 data against Social Security Administration and Department of Homeland Security records. It is voluntary for most private employers, but mandatory in two situations. Federal contractors whose contracts contain the FAR E-Verify clause, run longer than 120 days, and exceed $150,000 must enroll. More than 20 states also require E-Verify for at least some employers, from state agencies and their contractors up to all private employers.

Employers enrolled and in good standing with E-Verify also gain access to a remote document inspection option. Instead of examining originals in person, you can review copies transmitted electronically and then verify them during a live video call with the employee.⁶ You must keep clear copies of the documents for the standard retention period and must offer the alternative consistently to all employees at a given site to avoid a discrimination claim. Non-E-Verify employers still have to examine original documents face to face.

Record Retention and Government Audits

Completed I-9 forms are not filed with any agency. They stay with you and must be produced on demand. Federal regulations require you to keep each form for three years after the date of hire or one year after employment ends, whichever is later.⁷ Paper, scanned electronic copies, and microfilm all count.

When Immigration and Customs Enforcement opens an inspection, it serves a Notice of Inspection giving you at least three business days to hand over the requested forms.⁸ Investigators look for missing forms, blank fields, reliance on documents that were not acceptable, and patterns suggesting you knew a worker lacked authorization. Keeping I-9 files separate from general personnel records speeds retrieval and reduces the risk of disclosing unrelated information.

Mergers and Acquisitions

If you acquire another company, you can either adopt the seller’s existing I-9s or complete new ones for every acquired employee. Adopting the old forms is faster, but you inherit liability for every error on them. Buyers who want a clean slate often re-verify the entire acquired workforce rather than gamble on the predecessor’s compliance history.

Fixing Mistakes and the Good Faith Defense

During an audit, ICE separates technical errors from substantive violations. Technical mistakes, such as a missing middle initial or a date written in the wrong format, produce a correction notice that gives you at least 10 business days to fix them.⁹ Corrections made in that window carry no fine. Anything left uncorrected becomes a substantive violation with a monetary penalty.

To correct a paper I-9, draw a line through the wrong information, write in the correct information, and initial and date the change. Never use correction fluid or erase anything, because auditors treat concealed changes as a red flag. When a form has so many problems that line-through corrections would be unreadable, USCIS allows you to redo the section on a new form with a written explanation attached to the original.¹⁰ Only the employee (or their preparer) can fix Section 1; only you or your authorized representative can fix Section 2.

IRCA also provides an affirmative defense. If you can show you followed the verification requirements of the statute in good faith, that compliance is a legal shield against a charge of knowingly hiring an unauthorized worker.² The defense does not erase paperwork fines, but it can be the difference between a civil penalty and a criminal case.

The Penalty Ranges

IRCA’s fines scale with the type of violation and how many times you have been caught. The Department of Homeland Security adjusts the dollar amounts every year for inflation. The most recent adjustment, effective January 2, 2025, sets these ranges:¹¹

Paperwork violations (incomplete or missing I-9 forms): $288 to $2,861 per form
Knowing-hire violations, first offense: $716 to $5,724 per unauthorized worker
Knowing-hire violations, second offense: $5,724 to $14,308 per unauthorized worker
Knowing-hire violations, third or subsequent offense: $8,586 to $28,619 per unauthorized worker

The math gets ugly quickly. A company found with 50 missing I-9 forms could face more than $140,000 in paperwork penalties before any knowing-hire charge is added.

Criminal prosecution is reserved for employers that show a pattern or practice of hiring unauthorized workers. A conviction carries a fine of up to $3,000 per unauthorized worker and up to six months of imprisonment.¹² Criminal cases are rarer than civil audits, but ICE has pursued them against employers from meatpacking plants to landscaping companies when the evidence shows deliberate, repeated violations.

Anti-Discrimination Rules

The verification process cannot become a tool for bias. Under 8 U.S.C. § 1324b, you cannot discriminate based on citizenship status or national origin when hiring, recruiting, or firing workers who are legally authorized to work.¹³ Protected individuals include citizens, permanent residents, refugees, asylees, and other workers with valid authorization.

The most common violation is document abuse: demanding a specific document such as a green card when the employee has offered other acceptable ones, or requiring more documents than the I-9 calls for. Civil penalties for discrimination begin at $250 per individual for a first offense under the statute’s base amounts, with higher tiers for repeat offenders, and those figures are adjusted upward for inflation each year.

Social Security No-Match Letters

A Social Security Administration no-match letter tells you that a worker’s name or Social Security number does not match SSA records. The letter says nothing about immigration status. A mismatch can come from a name change after marriage, a data entry error, or an unreported legal name. Firing or disciplining a worker based solely on a no-match letter can trigger an anti-discrimination complaint.¹⁴ The Department of Justice tells employers to give workers a reasonable period to resolve the discrepancy and to avoid treating the letter as evidence that authorization is missing.

What IRCA No Longer Offers

IRCA also created a one-time amnesty program in 1986 for long-term undocumented residents and a separate track for special agricultural workers.¹⁵¹⁶ Both application windows closed decades ago, and no new applications can be filed. If a job applicant mentions IRCA legalization, it is a reference to a status already granted, not a program you can still sponsor them through. Your obligations begin and end with the I-9, the recordkeeping, the anti-discrimination rules, and (where applicable) E-Verify.
