I-9 Audit Checklist: Every Item to Check Before an ICE Inspection

An I-9 audit checklist helps employers review their Form I-9 records for completeness, accuracy, and compliance before an internal review or government inspection. Whether you are conducting a routine self-audit or preparing for a U.S. Immigration and Customs Enforcement (ICE) Notice of Inspection, this step-by-step checklist covers every item you need to verify — from Section 1 employee information to document retention timelines.

Print it, share it with your HR team, and work through it one form at a time.

Who this checklist is for: HR managers, compliance officers, business owners, and anyone responsible for maintaining Form I-9 records.

Why You Need an I-9 Self-Audit Checklist

ICE can audit any employer at any time. There is no minimum company size, no safe industry, and no advance warning required beyond the three-business-day notice that comes with a Notice of Inspection (NOI). When that notice arrives, your I-9 records either pass or they do not.

The financial stakes are real. Fines for substantive I-9 violations range from $281 to $2,789 per form for a first offense. An employer with 100 employees and systematic errors could face $28,000 or more in penalties from a single audit — and that is before any charges related to knowingly employing unauthorized workers.

The good news: most I-9 errors are technical and correctable. A missing signature, an incomplete address, a late Section 2 completion date — these are problems you can identify and fix before ICE does. The key is finding them first.

A structured I-9 compliance checklist turns a vague intention ("we should review our I-9s") into a concrete, repeatable process. It ensures you check every field, every section, every form — instead of skimming through a stack of folders and hoping for the best.

If you are not sure what would cause ICE to select your company for an audit in the first place, read our companion article: What Triggers an I-9 Audit?. For general background on the audit process, see What Is a Form I-9 Audit?. And for broader I-9 audit preparation tips, see our 10 Tips for Preparing for an ICE Audit.

Before You Start — What You Need

Before working through this I-9 audit checklist, gather the following materials:

• All Form I-9 records for current employees. Every active employee should have a completed Form I-9 on file.
• I-9 forms for terminated employees still within the retention window. The retention period is three years after the date of hire or one year after the date of termination, whichever is later. For a full explanation, see How Long to Keep I-9 Forms.
• Access to E-Verify records (if your company is enrolled in E-Verify).
• A copy of the current Form I-9 instructions. The current revision date is 08/01/2023. Note: forms with this revision date exist with two different expiration dates (07/31/2026 and 05/31/2027). After August 1, 2026, only the 05/31/2027 version may be used. Download it from uscis.gov/i-9.
• The Lists of Acceptable Documents (Lists A, B, and C). See the full list of valid documents for Form I-9 or the official USCIS reference at uscis.gov/i-9-central/form-i-9-acceptable-documents.
• A quiet workspace and uninterrupted time. This takes longer than you think — budget 5 to 10 minutes per form for a thorough review.
• A spreadsheet or tracking sheet to log errors. Suggested columns: Employee Name, Error Type, Section, Corrected (Y/N), Date Corrected.

The Complete I-9 Audit Checklist

This is the core of the guide. Work through each section for every Form I-9 on file. Check each item, note any errors in your tracking sheet, and do not make corrections yet — document everything first, then correct in a separate pass using the procedures described in the next section.

Section 1 — Employee Information and Attestation

Review each Form I-9's Section 1 for the following:

1. Confirm Section 1 is completed. The section should not be blank or partially filled in.
2. Verify the employee's full legal name is present. Check for last name, first name, and middle initial (if applicable). The name must match the employee's identity documents.
3. Verify the address is complete. Look for street address, city, state, and ZIP code. P.O. boxes alone are not acceptable.
4. Confirm the date of birth is present. The field should contain a valid date in MM/DD/YYYY format.
5. Check whether the Social Security number is present. This field is required if your company uses E-Verify. If your company does not use E-Verify, the SSN is voluntary — its absence is not an error. Note this distinction on your tracking sheet so you do not flag it incorrectly.
6. Confirm the employee selected a citizenship or immigration status. One of the four boxes must be checked: U.S. citizen, noncitizen national, lawful permanent resident, or alien authorized to work. No box checked is a violation.
7. If the employee selected "lawful permanent resident" — verify the USCIS Number or A-Number is present. This field is required for that status selection.
8. If the employee selected "alien authorized to work" — verify the work authorization expiration date is present and that a USCIS Number, A-Number, or Form I-94 admission number is recorded. Both fields are required for this status.
9. Confirm the employee signed and dated Section 1. A missing signature is one of the most common audit findings and one of the easiest to catch.
10. Verify Section 1 was completed on or before the employee's first day of employment. Compare the date in Section 1 against your hire records. Section 1 completed after the first day of work is a timing violation.
11. If a preparer or translator assisted the employee — confirm Supplement A is completed and signed. Every person who helped prepare or translate Section 1 must complete a separate Supplement A block. Missing Supplement A forms are frequently overlooked.

Section 2 — Employer Review and Verification

Review each Form I-9's Section 2 for the following:

1. Confirm Section 2 is completed. The section should not be blank. A blank Section 2 is treated the same as a missing Form I-9.
2. Verify Section 2 was completed within three business days of the employee's first day of employment. Compare the completion date in Section 2 against the hire date. A form completed on business day four is a violation, even if every field is otherwise correct. Important exception: if the job lasts less than three business days, Section 2 must be completed no later than the first day of work for pay.
3. Verify the employee presented documents from List A, OR one document from List B AND one document from List C. Only one combination is valid — not both. If both List A and Lists B+C are filled in, that is an error.
4. Confirm the document title, issuing authority, document number, and expiration date are recorded for each document. Every field must be filled in. Partial entries count as incomplete.
5. Verify the documents are acceptable per the Lists of Acceptable Documents. Documents must be unexpired at the time of initial hire. Note two exceptions: employees may present an acceptable receipt in place of a document while waiting for the actual document, and USCIS may automatically extend certain Employment Authorization Documents (EADs) beyond their face expiration date — an auto-extended EAD is considered unexpired for I-9 purposes. See Valid Forms of ID for Form I-9 for the full list.
6. Confirm the employer or authorized representative signed and dated Section 2. An unsigned Section 2 renders the entire form deficient.
7. Verify the employer's business name and address are present. Both fields are required.
8. Check that the hire date recorded in Section 2 matches the employee's actual first day of employment. Discrepancies between the I-9 hire date and your payroll or HR system records are a red flag during audits.
9. Confirm the employee was physically present when presenting documents. If not, was a properly designated authorized representative used? If your company has remote or distributed employees, learn more about remote I-9 verification and how trained authorized representatives can complete Section 2 via video call.

Supplement B — Reverification and Rehires

Review Supplement B (formerly Section 3) for all applicable employees:

1. For employees with expiring work authorization — verify Supplement B was completed on or before the expiration date. Late reverification is one of the most common and most penalized audit findings. Check dates carefully.
2. Confirm the new document information is recorded. Check for document title, document number, and expiration date. All three fields are required.
3. Confirm the employer signed and dated the reverification. An unsigned reverification is incomplete.
4. Verify only List A or List C documents were used for reverification. List B documents (identity-only documents like a driver's license) are not used for reverification — only documents that establish employment authorization. This is a common mistake.
5. Confirm reverification is not present for exempt employees. Reverification is never required for U.S. citizens, noncitizen nationals, or lawful permanent residents who presented a Permanent Resident Card (Form I-551). If you see reverification entries for these employees, they may indicate an over-verification practice that could raise discrimination concerns.
6. Confirm reverification was completed on the correct Form I-9 edition. Using an outdated form version for reverification is a separate violation, even if the original I-9 was completed on the correct form at the time of hire.
7. For rehired employees — verify the rehire date is recorded and reverification was completed if the employee's previous work authorization has expired. Rehires within three years of the original I-9 date may use the existing form, but only if work authorization is still valid.

Document Retention Compliance

1. Confirm a Form I-9 is on file for every current employee. A missing form is one of the most serious findings in an audit. Cross-reference your I-9 files against your current employee roster.
2. For terminated employees — verify each Form I-9 is retained for the required period. The retention rule: three years after the date of hire OR one year after the date of termination, whichever is later. Calculate both dates and keep the form until the later one passes. For a detailed guide, see How Long to Keep I-9 Forms.
3. Confirm I-9 forms beyond the retention period have been securely destroyed. Keeping forms longer than required creates unnecessary audit exposure — every extra form is another form ICE can review and fine you for. Shred paper forms or permanently delete electronic records.
4. Verify I-9 forms are stored separately from general personnel files. This is not legally required, but it is a widely recommended best practice. Separate storage makes audit response dramatically faster and prevents exposing unrelated employee information during an ICE inspection. If your I-9s are mixed in with personnel files, consider separating them as part of this audit.

E-Verify Compliance (If Enrolled)

If your company participates in E-Verify, review the following for each employee hired after your enrollment date:

1. Confirm an E-Verify case was created for every new hire within three business days of the employee's start date. Late case creation is a violation of the E-Verify Memorandum of Understanding (MOU).
2. Verify all E-Verify cases are closed. Open or lingering cases are a red flag during an audit and may indicate unresolved Tentative Nonconfirmations (TNCs).
3. Confirm all TNCs were handled properly. The employee must be notified in writing, given the opportunity to contest the finding, and referred to the appropriate government agency (Social Security Administration or Department of Homeland Security) if they choose to contest. Document each step.
4. Verify no adverse actions were taken against an employee before the E-Verify case was fully resolved. Terminating, suspending, or reducing hours based on an unresolved TNC is a violation of anti-discrimination provisions.
5. Confirm the E-Verify company identification number is posted where required. Display the E-Verify participation poster and the Right to Work poster in a visible location at each hiring site.

Common I-9 Errors and How to Correct Them

A Form I-9 audit almost always turns up errors. The question is not whether you will find problems — it is how many and how serious. Here are the seven most common issues found during internal I-9 audits, along with the correct correction procedure for each.

The cardinal rule: never back-date or use white-out on a Form I-9. All corrections must use a single-line strikethrough, the correct information written nearby, and the corrector's initials and the current date. For forms with multiple errors across a section, the M-274 permits redoing that section on a new Form I-9 — attach it to the original with a written explanation and do not destroy the old form. ICE auditors look for correction patterns. Clean, dated corrections demonstrate good faith. Alterations that look like cover-ups make things significantly worse.

1. Missing Employee Signature in Section 1

The error: The employee did not sign or date Section 1.

How to correct it: If the employee is still employed, have them sign and date Section 1 using today's date — not the original hire date. Attach a brief note explaining that the signature was added during an internal audit. If the employee is no longer with the company, you cannot correct this. Document the finding in your audit log and move on.

2. Section 2 Completed Late (Past the Three-Day Window)

The error: The employer completed Section 2 more than three business days after the employee's first day of employment.

How to correct it: This error cannot be undone. The dates are what they are. Document the late completion in your audit log. Do not alter the dates — changing them would constitute falsification, which carries far steeper penalties than a late completion. Going forward, implement a process to ensure all future I-9s meet the three-day deadline.

3. Wrong or Missing Document Information in Section 2

The error: A document title, number, issuing authority, or expiration date is missing or incorrect in Section 2.

How to correct it: Draw a single line through the incorrect or missing entry. Write the correct information nearby. Initial and date the correction. If you need to verify the document details, consult the employee's copies (if available) or ask the employee to present the original documents again.

4. Using an Outdated Form Version

The error: The Form I-9 was completed on an expired edition of the form. The current edition is dated 08/01/2023.

How to correct it: Complete a new Form I-9 on the current form edition. Attach the old form to the new one with a note explaining that the new form was completed during an internal audit to replace an outdated version. Do not destroy the original — keep both forms together.

5. Reverification Not Completed on Time

The error: An employee's work authorization expired and Supplement B was not completed on or before the expiration date.

How to correct it: Complete the reverification immediately using the current date. The gap between the expiration date and the correction date will be visible, but a late reverification is far better than no reverification at all. Document the finding and the correction date in your audit log.

6. I-9 Completed on the Wrong Form Edition

The error: The employer used the wrong version of Form I-9 — not one that has since expired, but one that was already outdated at the time of hire.

How to correct it: Complete a new Form I-9 on the correct edition. Staple the incorrect form to the new one and note the reason for the correction. Do not destroy the original.

7. Missing Supplement A for Preparer or Translator

The error: A preparer or translator assisted the employee with Section 1, but Supplement A was never completed.

How to correct it: Have the preparer or translator complete and sign a Supplement A now, using the current date. If the original preparer or translator is unavailable, note this in your audit log — this error cannot be fully corrected retroactively, but documenting it shows good faith.

For official guidance on I-9 correction procedures, refer to the USCIS Handbook for Employers (M-274).

What Happens If ICE Audits You (And You Are Not Prepared)

If you have not conducted a self-audit and ICE comes knocking, here is what you face.

The process. ICE delivers a Notice of Inspection (NOI) — by mail, fax, or in person. You have three business days to produce your I-9 records. Not three weeks. Not "when you get around to it." Three business days. If your forms are scattered across filing cabinets, multiple offices, or a disorganized HR system, that deadline becomes a crisis.

The penalties. Current ICE audit fine amounts, adjusted annually through the Federal Register:

• Substantive violations (missing forms, incomplete sections, failure to produce Form I-9): $281 to $2,789 per form, first offense
• Knowingly hiring or continuing to employ unauthorized workers: $698 to $5,579 per worker (first offense), escalating to $27,894 per worker for third and subsequent offenses
• Document fraud: $583 to $4,667 per violation, first offense

These penalties are assessed per form, not per company. Fifty incomplete I-9s at $281 each is $14,050 — and that is the minimum first-offense amount. See our full breakdown of current ICE audit fines for detailed penalty tables and real-world examples.

Mitigating factors. ICE considers an employer's good-faith compliance efforts when determining penalty amounts. Conducting regular self-audits and documenting your correction efforts are among the strongest mitigating factors you can demonstrate. This is one of the most practical reasons to use an I-9 audit checklist proactively — your audit trail becomes evidence of good faith.

Aggravating factors. A pattern of violations, failure to correct previously identified issues, and an unusually high percentage of deficient forms all increase penalty amounts.

If you have already received a Notice of Inspection, read our guide on how to handle an ICE audit.

Frequently Asked Questions

How often should you do an I-9 self-audit?

Most compliance experts recommend conducting an internal I-9 audit at least once a year. Employers in industries frequently targeted by ICE — such as agriculture, hospitality, construction, and manufacturing — should consider auditing every six months. Regular self-audits demonstrate good-faith compliance and can serve as a mitigating factor if ICE does inspect your records.

Can you correct errors on a Form I-9?

Yes. Draw a single line through the incorrect information, write the correct information nearby, and initial and date the correction. Never use white-out or back-date corrections. For forms with multiple errors, you may redo a section on a new form — attach it to the original with a written explanation. The correction should be made by the person who originally completed that section of the form, when possible. For detailed correction procedures, refer to the USCIS Handbook for Employers (M-274).

What is the penalty for a missing Form I-9?

Fines for failing to produce a Form I-9 during an audit range from $281 to $2,789 per form for a first offense. Penalties increase significantly for repeat violations. Because fines are assessed per form, even a small number of missing I-9s can result in thousands of dollars in penalties. See our full ICE audit fines guide for current penalty tables.

Should I-9 forms be kept separate from personnel files?

While not legally required, storing Form I-9 records in a separate file — apart from general personnel records — is a widely recommended best practice. It makes audit response faster because you can produce your I-9s without handing over unrelated employee information. It also reduces the risk of exposing private data during an ICE inspection. If ICE requests your I-9 files, you hand over one binder or folder — not your entire HR filing system.

How long do you have to respond to an ICE Notice of Inspection?

Employers must produce their I-9 records within three business days of receiving a Notice of Inspection (NOI) from ICE. Having organized, accessible records is critical. This is one of the strongest practical reasons to conduct regular self-audits and to store your I-9 forms in a system — whether digital or physical — that allows fast retrieval.
