When an employer asks “is this a fineable error?” the honest answer is: it depends on which field, and it changed in March 2026. ICE prices paperwork and substantive violations per form — it does not publish a fixed dollar figure per error type — so the practical question is which errors count as substantive (fineable from the start) versus technical (curable within a grace window). This page sorts the common errors into those buckets.
The range that applies to every row below: paperwork and substantive I-9 violations run $288–$2,861 per form, assessed per form. Knowingly hiring or continuing to employ an unauthorized worker is a separate category, up to about $28,619 per worker for repeat offenders. For the full schedule and how ICE lands on a number within the range, see the 2026 I-9 civil penalties page.
The 2026 shift: technical errors that became substantive
The single most important 2026 change is not the dollar amounts — the government froze those at 2025 levels — it is which errors qualify for a fine. In a March 2026 fact-sheet update, ICE reclassified several errors that were previously treated as correctable technical violations as substantive:
- A missing employee date in Section 1
- A missing employer name, title, or hire date in Section 2
- A missing certification date in Section 2
Before, these often came with the 10-business-day grace window during an inspection. Now they carry a per-form penalty from the start — which is exactly why they are worth catching in a self-audit before ICE ever looks.
Error-by-error: what gets fined and how to fix it
Substantive — fineable from the start
Missing Form I-9 entirely
Whole form. No I-9 on file for an employee who should have one is the most serious paperwork violation and sits at the high end of the per-form range. You cannot backdate a new form to cover the gap. Complete a fresh I-9 today using today's real date, attach a signed memo explaining when and why it was created, and never alter the hire date.
Substantive
Late Form I-9 (completed after the deadline)
Whole form. Section 1 must be done by the first day of work for pay and Section 2 within three business days of hire. A form completed late is citable even if every field is now correct. There is no clean fix for lateness itself — do not backdate. Keep the form as-is with its true completion date and document the circumstance.
Substantive
Wrong / outdated form edition
Whole form. Using a superseded edition of Form I-9 is itself a citable violation, independent of how the fields were filled in. Confirm you are on the current USCIS edition, then complete a new current-edition form for the employee with today's date and staple it to the original.
Substantive
Missing employee signature or attestation date (Section 1)
Section 1. An unsigned Section 1, or a missing status-attestation box, is a substantive violation. Only the employee can cure it: have them sign and date the correction with today's real date — the employer cannot sign Section 1 for them.
Reclassified in March 2026 — now substantive
Missing employee date in Section 1
Section 1. This used to be treated as a curable technical error. The March 2026 ICE fact-sheet update moved a missing Section 1 employee date into the substantive, fineable bucket. The employee lines through nothing (the field was blank) and simply enters and initials the date using today's real date, with a dated note that the correction was made on self-audit.
Reclassified in March 2026 — now substantive
Missing employer business name, address, title, or hire date (Section 2)
Section 2. The March 2026 update reclassified a missing employer name, title, hire date, or the certification date in Section 2 as substantive rather than technical. Only the employer representative who actually examined the employee's documents may add the missing entry, initial, and date it today.
Substantive
Incomplete Section 2 document details
Section 2. Missing document title, issuing authority, number, or expiration for the List A, or List B + List C, documents you examined is substantive. Re-examine the original documents the employee presented (not new ones you request), record the details, and initial and date the correction today.
Discrimination exposure — separate track
Over-documentation / specifying which documents (Section 2)
Section 2. Requiring specific documents, rejecting valid ones, or demanding more than the form requires is not a paperwork fine — it is a document-abuse / discrimination issue enforced by the DOJ's IER, with its own penalty track per affected individual. The fix is process, not a line-edit: stop specifying documents and let employees choose from the Lists of Acceptable Documents.
Substantive once the date has passed
Missed reverification (Supplement B)
Supplement B. Failing to reverify expiring temporary work authorization on time is a substantive violation. Reverify now on Supplement B using today's date, and put every future work-authorization expiration on a tracker so the next one never slips.
Knowing-hire — far higher, per worker
Knowingly hiring / continuing to employ an unauthorized worker
Beyond paperwork. This is a separate and much more serious category, assessed per worker rather than per form and reaching up to about $28,619 per worker for repeat offenders — with potential criminal exposure for a pattern or practice. No self-audit line-edit addresses this. If you suspect it, that is an immigration-attorney conversation, not a paperwork fix.
The correction rule that applies to every fixable row: line through the wrong entry, write the correct one, then initial and date it with today's real date. Never backdate, white-out, or re-create a form — a falsified “fix” can carry worse liability than the original error. Only the employee corrects Section 1; only the employer representative who examined the documents corrects Section 2. The full method is in the 2026 I-9 self-audit checklist.
Why the error count matters more than the error type
Because paperwork penalties are assessed per form, the total exposure is driven by how many flawed I-9s you have, not by how severe any single error is. A 2% substantive-error rate across a few thousand forms is dozens of separate violations, each in the $288–$2,861 range. That is why the reclassification matters: moving a few common fields into the substantive bucket can meaningfully raise a high-headcount employer's count of fineable forms.

I-9 penalties by error type FAQ
Which I-9 errors actually get fined in 2026?
Substantive violations carry a per-form penalty from the start: a missing, late, or wrong-edition form; an unsigned or undated Section 1; incomplete Section 2 document details; and missed reverifications. Technical or procedural errors are minor and, during an inspection, ICE typically gives at least 10 business days to correct them — if you don't cure them in that window they become substantive and fineable. Paperwork and substantive violations run about $288 to $2,861 per form.
What did the March 2026 rule change reclassify?
A March 2026 ICE fact-sheet update moved several errors that used to be treated as correctable technical violations into the substantive, fineable bucket — including a missing employee date in Section 1, and a missing employer name, title, hire date, or certification date in Section 2. More of what used to be a free correction now carries a per-form penalty, which raises the value of catching those specific fields in a self-audit.
How much is each I-9 error worth?
Paperwork and substantive violations are priced per form in a range of about $288 to $2,861, and ICE places each form within that range based on your overall error rate, business size, good faith, and history — it does not publish a fixed dollar amount per individual error type. Knowingly hiring or continuing to employ an unauthorized worker is a separate category assessed per worker, up to roughly $28,619 for repeat offenders. Because paperwork fines multiply per form, the count of flawed I-9s drives the total more than the severity of any single error.
What's the difference between a technical and a substantive violation?
Technical or procedural failures are minor and curable — during an inspection ICE typically gives at least 10 business days to fix them before they count. Substantive violations carry a per-form penalty from the start. The 2026 reclassification is significant precisely because it moved several formerly-technical items into the substantive bucket, so they no longer come with that grace window.
How do I fix these errors the correct way?
Line through the incorrect entry, write the correct information, then initial and date the change with today's real date. Never backdate, white-out, erase, or re-create a form to look like it was always correct — a falsified 'fix' can carry far worse liability than the original error. The right person signs: only the employee corrects Section 1, and only the employer representative who examined the documents corrects Section 2. Keep a dated log of every gap found and every correction made — that trail is your good-faith evidence.
