How to Correct a Form I-9 the Right Way

Mistakes on Form I-9 are common. A blank field, a transposed document number, a late Section 2 date, or a mismatched citizenship status box can turn up in an internal review or a government inspection. Many of those problems can be fixed. The way you fix them matters as much as the fix itself.

Wrong corrections can look like tampering. Erasing, white-out, backdating, and rewriting a form as if the error never happened are all worse than leaving a small mistake alone. This guide covers how to correct a Form I-9 the right way: who should make the change, the strike-through method, when a new form is better, and what never to do.

Why correction method matters

Form I-9 is an employment eligibility record. Inspectors look not only at whether the form is complete, but also at whether it was completed honestly and on time. A clean correction that shows what was wrong, what was fixed, and when, demonstrates good faith. A form that looks scrubbed can raise questions about whether the employer tried to hide something.

USCIS guidance, including the Handbook for Employers (M-274) and I-9 Central, describes how employers and employees should make corrections. The core idea is simple: the record should show the original entry and the correction, not a rewritten history.

Who corrects which section

Not every error belongs to the employer.

• Section 1 is the employee's section. The employee should correct errors in their own attestation, personal details, citizenship or immigration status, and alien or admission numbers. The employer shouldn't rewrite Section 1 for the employee.
• Section 2 and Supplement B (formerly Section 3) are the employer's responsibility. The employer, or the authorized representative who completed that part, corrects document details, the first day of employment, certification fields, and reverification or rehire entries.
• If the employee is no longer available to correct Section 1, the employer generally can't invent a substitute signature. Attach a signed and dated note explaining the situation, and get legal advice for the specific case.

The standard correction method

For a paper Form I-9, the accepted approach is:

1. Draw a single line through the incorrect information. Don't scribble it out so heavily that the original can't be read.
2. Enter the correct information nearby, usually above or next to the struck text.
3. Initial and date the correction. Use the date you actually make the change, not the date the form was originally completed.

That pattern applies whether you're fixing a typo in a document number, adding a missing issuing authority, or correcting a status box after the employee has updated Section 1.

If the form is electronic, your system should create a comparable audit trail: what changed, who changed it, and when. Never overwrite an electronic record in a way that erases the prior version with no history.

What never to do

• Don't use white-out, correction tape, or heavy erasure. Obscuring the original entry makes the form look altered.
• Don't backdate. If Section 2 was completed late, don't change dates to make the timeline look timely. Correct forward with the real dates and, where helpful, a brief note about when the error was found and fixed.
• Don't destroy the original and start over as if nothing happened, unless you attach a new section to the original and document why. Replacing a form with a "clean" copy can look like concealment.
• Don't have the employer rewrite Section 1 to match what the employer thinks the employee meant.
• Don't wait for a Notice of Inspection to start fixing forms. Corrections made only after a government request can look reactive. Regular internal audits are the better path.

When a new Form I-9 or new section is appropriate

Sometimes a form has so many errors that line-by-line corrections would make it unreadable. In that case:

• For many Section 2 errors, the employer can complete a new Section 2 and attach it to the original Form I-9, with a signed and dated note explaining why.
• For Section 1, if the employee is available, they can complete a new Section 1 attached to the original, again with a clear note. Don't ask the employee to backdate it.
• An entirely new Form I-9 can make sense when the original is badly damaged, missing critical parts, or too densely corrected to review. Keep the original with the new form and document why the new form was created.

Special cases that trip teams up

Missing forms

You can't correct a form that was never completed. If you discover a missing I-9 for a current employee, complete one as soon as possible with the actual completion dates. Don't invent earlier dates. For former employees whose forms are missing and whose retention period has not ended, document the gap and consult counsel.

Late completion

A late Section 1 or Section 2 can't be made timely by changing dates. Complete what's missing accurately, and note when the late completion was discovered. Onboarding checklists and system deadlines prevent this better than creative paperwork.

Wrong document recorded

Strike through the incorrect Section 2 document details, record the correct ones, and initial and date. If the employee still has the documents, re-examine them when you correct. If copies were retained, compare carefully so you don't introduce a second error.

Citizenship or immigration status errors

Status boxes in Section 1 belong to the employee. If the wrong box was checked, the employee should strike through, correct, initial, and date. Handle any related Section 2 or Supplement B updates separately under the employer rules.

Reverification mistakes on Supplement B

Treat Supplement B like Section 2: strike through, initial, and use the real correction date. Don't reverify U.S. citizens or permanent residents solely because of expired identity documents, and don't use Supplement B to quietly rewrite earlier sections.

Building a correction habit into your process

• Train anyone who touches I-9s on the strike-through rule and on who owns each section.
• Run periodic internal audits with a written scope, consistent sampling, and documented fixes. Apply the same standards to every employee to avoid discrimination concerns.
• Use an electronic I-9 system that blocks incomplete forms where possible and records every change with an audit trail.
• Keep a short correction log for paper files when a note helps: what was found, what was fixed, and the date.

How Clear I-9 helps

Clear I-9 by TRAK reduces the need for corrections with error checks before a form is signed, and when something still needs fixing, every change is recorded with what changed and when. Workflows, reporting, and tracking surface incomplete forms and approaching deadlines so late completion is less common. Electronic signatures and document imaging keep the record together, and instant E-Verify ties case results to the same employee file when you use E-Verify.
