ICE I-9 Audit Process: Notices, Violations, and Fines

An ICE I-9 audit process begins when Immigration and Customs Enforcement serves your business with a Notice of Inspection, gives you at least three business days to produce your I-9 forms and payroll records, and then reviews them line by line for errors that can carry civil fines of $288 to $28,619 per violation. The outcome depends on what auditors find, how you classify as an employer under five statutory factors, and whether you respond to their notices on time.

What ICE Asks For and How Fast

The audit formally starts with a Notice of Inspection (NOI), delivered in person to a company representative or sent by certified mail. Federal regulations give you at least three business days from service to gather the records ICE has requested.¹

The core request is every completed Form I-9 for your current employees hired after November 6, 1986.² You also need to produce I-9s for former employees still within the retention window: three years from the date of hire or one year after termination, whichever is later.³ Someone terminated two years ago but hired five years ago still needs a form on file, because the three-year-from-hire clock hasn’t run out.

Beyond the forms themselves, expect to hand over business licenses and complete payroll records with names, hire dates, and termination dates. Agents use payroll data to match every person on your roster against a corresponding I-9. A name on payroll with no I-9 behind it is one of the fastest ways to generate a substantive violation.

Three business days is not much time if the binder hasn’t been touched in years. Ignoring the NOI or stalling is not a viable option; the notice creates a legal obligation to cooperate, and delay invites escalation.

How the Review Works

Once you produce the records, agents begin a line-by-line review, usually at your place of business or a local Homeland Security Investigations field office. They compare each I-9 against your payroll data and cross-reference the information against Department of Homeland Security databases to verify Social Security numbers and work authorization.¹

The review can take weeks or months depending on the size of your workforce. During that time, agents may reach out to clarify discrepancies or ask for missing information. Responding promptly matters for the timeline and for the “good faith” factor ICE weighs later when calculating penalties.

Substantive Violations vs. Technical Failures

ICE sorts problems into two tiers, and the difference is money.

Substantive violations are errors that undermine the verification itself. Missing signatures, entire blank sections, failure to examine physical documents, and accepting expired documents all fall here. These carry penalties because they suggest a fundamental step was skipped.⁴

Technical or procedural failures are minor oversights, like a missing middle initial or a date in the wrong format, that don’t compromise the underlying verification. When ICE identifies these, you get at least ten business days to correct them.⁴ Fix them within that window and they stay technical. Miss the window and they convert into substantive violations that carry fines.¹

The statute also recognizes good faith. If you made an honest effort but fell short on minor details, ICE can take that into account when deciding how to classify errors. A consistent pattern of checking documents and completing forms, even imperfectly, carries weight.

What the Fines Look Like

Penalty amounts are adjusted annually for inflation. For 2026 the Office of Management and Budget directed agencies to continue using 2025 levels because October 2025 inflation data was unavailable. The current ranges:

Paperwork Violations

Failing to properly complete, retain, or produce I-9 forms carries a fine of $288 to $2,861 per form.⁵ These are per-form penalties. A business with 50 deficient I-9s faces potential exposure of $14,400 to $143,050.

Knowingly Hiring or Continuing to Employ Unauthorized Workers

These penalties are steeper because they involve actual knowledge that a worker lacks authorization:

First offense: $716 to $5,724 per unauthorized worker
Second offense: $5,724 to $14,308 per unauthorized worker
Third or subsequent offense: $8,586 to $28,619 per unauthorized worker⁵

How ICE Sets the Specific Amount

ICE doesn’t pick a number from within the range at random. After determining a base fine, the agency applies five statutory factors that can each adjust the total up or down by 5%:¹

Business size, with smaller employers potentially seeing a downward adjustment
Good faith, meaning evidence of proactive compliance efforts
Seriousness, where missing an entire section weighs more than a formatting error
Number of unauthorized workers involved
Prior violations, with a clean history helping and repeat offenses hurting

If all five factors cut against you, the total increases by 25%. If all five favor you, it drops by 25%. Most employers land somewhere in between.

The Notices You Might Receive

When the review wraps up, ICE delivers one or more written notices telling you where you stand.¹

A Notice of Inspection Results, sometimes called a compliance letter, means your records met all federal requirements and no further action is needed.
A Notice of Technical or Procedural Failures means ICE found minor errors and is giving you at least ten business days to correct them before they become substantive violations.
A Notice of Suspect Documents means ICE determined that one or more employees’ documentation doesn’t appear valid. It warns of criminal and civil penalties for continuing to employ those workers and gives you and the affected employees a chance to provide valid work authorization.
A Notice of Intent to Fine (NIF) means ICE identified substantive violations, uncorrected technical failures, or knowing-hire violations and is proposing civil penalties.

A Notice of Suspect Documents doesn’t automatically require you to fire anyone. It puts you on notice. Continuing to employ someone after learning they lack valid authorization exposes you to “continuing to employ” penalties, which run substantially higher than paperwork fines.

Correcting Errors the Right Way

Whether you’re fixing problems during your own internal review or responding to ICE’s findings, corrections follow strict rules. Draw a single line through the incorrect entry, write the correct information nearby, then initial and date the correction. Attach a written explanation of what was wrong and why you’re correcting it.⁶

Two moves will make your situation worse: backdating and concealing changes. If you forgot to date Section 2 when you originally completed it, do not write in the original hire date. Enter the current date and initial it.⁶ Correction fluid or erasing text increases your liability and can look like evidence of fraud. ICE specifically flags backdating as a circumstance where a warning notice will not be issued; the agency treats it as a red flag that takes leniency off the table.¹

For forms with multiple errors or entire blank sections, you can complete a new I-9 and attach it to the original with a signed explanation. Never destroy the original. The correction history is part of what demonstrates good faith.

Challenging the Findings

A Notice of Intent to Fine is not a final order. You have 30 calendar days from receiving the NIF to request a hearing before an Administrative Law Judge at the Office of the Chief Administrative Hearing Officer (OCAHO), which sits within the Department of Justice.¹⁴ Miss that window and the proposed penalties become final by default.

OCAHO also runs a voluntary settlement officer program. If both sides consent, a neutral settlement officer mediates negotiations for up to 60 days, with a possible 30-day extension.⁷ Nothing said during settlement can be used against you if it falls through. If no agreement is reached, the case goes back to the ALJ for a hearing on the merits.

Employers commonly contest the number of violations, argue that ICE miscategorized technical failures as substantive ones, or present mitigating evidence the original auditors didn’t consider. Organized records and documented correction efforts strengthen any of these arguments.

When Criminal Charges Enter the Picture

Civil fines are the most common outcome, but ICE can refer cases for criminal prosecution when the evidence shows a pattern of knowingly hiring unauthorized workers. The criminal statute provides for a fine of up to $3,000 per unauthorized worker and up to six months of imprisonment for the entire pattern.⁸

A separate federal law targets employers who go beyond negligent hiring into actively concealing unauthorized workers. Harboring charges carry up to five years in prison, or up to ten years if the employer acted for commercial advantage.⁹ These cases are rare compared to civil I-9 penalties, but they are the reason experienced counsel warns clients never to ignore audit findings or continue employing workers they know are unauthorized.
