ICE changed which I-9 mistakes carry a fine in 2026, and the ten-day grace period that used to cover the common ones is gone. Here is what moved into the fineable column, and how to run a self-audit that catches those errors before an inspector does.
In March 2026, ICE widened what counts as a "substantive" I-9 error, which has major implications for most employers.
With the expansion of what is considered substantive, there is an increased risk of penalty from the moment an inspector finds these errors. Each substantive error carries a civil penalty of $288 to $2,861 per form. If your company has a large headcount, then a small error could compound into a hefty cost.
As with any compliance change, the best next step is to do a full internal review of your current situation and look for potential liabilities. That process begins by understanding what's changed.
What changed for I-9 compliance in 2026
Form I-9 errors fall into two categories: technical errors, which are minor and correctable, and substantive errors, which impact the integrity of the form or the verification behind it and carry civil penalties. Three changes stand out for employers:
- More than ten common clerical mistakes were reclassified. In March 2026, ICE updated its Form I-9 inspection fact sheet and moved them out of the technical column and into the substantive one.
- The correction window no longer applies to them. A technical error comes with at least ten business days to fix before a penalty attaches. A substantive error doesn't, so the reclassified mistakes are fineable the moment an inspector finds them, at the per-form range above.
- Inspections have increased. ICE issued Notices of Inspection in the first half of 2025 at roughly ten times the 2024 rate, across industries including construction, health care, hospitality, and manufacturing.
Taken together, these changes narrow the room for error on a form most companies treat as routine paperwork. The same mistakes are as common as they ever were. What's different is the cost of leaving one in a file.
What this means for employers
For employers, the change lands in two places: what an error can cost, and how little time there is to fix one once an inspection starts.
- Penalties are charged per form. The $288 to $2,861 range applies to each affected I-9, not to the review as a whole. The same missing date across a few hundred files turns a clerical habit into a real number.
- Willful violations cost far more. Knowingly hiring or continuing to employ a worker who isn't authorized starts at $716 to $5,724 for a first offense and climbs with each one after that.
- A prior clean audit may no longer hold. Errors flagged as technical in an earlier review and left uncorrected can now count as substantive, so a form that passed two years ago can fail today.
- An inspection moves quickly. Once a Notice of Inspection arrives, the substantive errors already in your files no longer come with time to remedy. The window to correct problems is before a notice shows up, not after.
The common thread is timing. These errors are correctable and the rules are knowable, but only while the schedule is still yours. A self-audit is how you find and fix them on your own terms rather than an inspector's.
How to run an I-9 self-audit
A self-audit is methodical work, and the steps below follow the same method Helios consultants used to clean up the I-9 files at a non-profit that had let them drift over several years.
1. Gather every I-9 and match it to your roster
Pull together all the I-9s you currently hold and list your active employees beside them. You're checking two things at once: that every current employee has a form on file, and that you aren't still holding forms for people who left long ago. At the non-profit, this first pass turned up both, a stack of forms for terminated staff and gaps for people still on the payroll. Sort the forms into current employees, former employees, and anyone missing a form before you correct anything.
2. Purge the forms you no longer need to keep
Check each former-employee form against the retention rule. You are required to keep an I-9 for three years after the date of hire or one year after the date of termination, whichever is later. Anything past that window for a terminated employee should be purged. Over-retention is its own liability, since every extra form in the file is one more an inspector can review. Even forms that should have been purged can trigger a penalty. State rules can add their own recordkeeping requirements, so check those too.
3. Review each remaining form section by section
Work through the forms one at a time, checking Section 1, the employee's part, and Section 2, yours. Look for the errors that now count as substantive: a missing hire date, an undated signature, an incomplete document entry, a missing employer title. Note what's wrong on each form before you fix anything, so you have a record of what the audit found. These were the same gaps that ran through the non-profit's files: missing hire dates, incomplete Section 2 documentation, and missing signatures.
4. Make corrections properly
Correct an error by drawing a single line through it, entering the correct information, then initialing and dating the change. Don't use white-out, and never backdate. Who makes the fix depends on the section. You can correct Section 2 yourself, but only the employee can correct Section 1, so reach out directly to anyone whose form needs a Section 1 fix. If someone has already left, note that you couldn't obtain the correction rather than making it for them.
5. Document every change and write an audit memo
Attach a short memo to each corrected form explaining what changed and why. Then write one overall audit memo that captures the scope of the review, the steps you took, the corrections you made, and the controls you're putting in place to keep new I-9s accurate going forward. That record does two jobs. It shows a good-faith effort to comply if an inspector ever asks, and it gives whoever handles I-9s next a standard to follow. It's also a good prompt to check whether it's time for a broader HR audit.

Frequently asked questions
Does ICE actually audit I-9s?
Yes. ICE issues a Notice of Inspection and reviews your I-9s directly. Inspections in the first half of 2025 ran at roughly ten times the 2024 rate, across construction, health care, hospitality, and manufacturing.
What triggers an I-9 audit?
An audit can follow a tip, an industry sweep, or a random selection, so there is not always a specific trigger. Because you cannot predict one, the practical answer is to keep your files ready year-round.
What is the difference between a technical and a substantive I-9 error?
A technical error is minor and correctable, and it comes with at least ten business days to fix before a penalty attaches. A substantive error affects the form's integrity or the verification behind it and is fineable immediately.
How much are I-9 fines in 2026?
Substantive paperwork violations run $288 to $2,861 per form, charged on each affected I-9. Knowingly employing an unauthorized worker starts far higher. DHS adjusts these amounts for inflation each year, so treat them as 2026 figures.
How long do I have to keep an I-9?
Keep each form for three years after the date of hire or one year after termination, whichever is later. Holding forms past that window adds files an inspector can review, so purge them once the retention period ends. Check your state's rules too.
Who is allowed to correct an I-9 error?
You can correct Section 2 yourself by lining through the error, entering the right information, and initialing and dating it. Only the employee can correct Section 1, so you have to reach out to them directly.
Can we bring in outside help for an I-9 audit?
Yes. An experienced HR partner can run the full review, corrections, and remediation. Where a case turns on complex work-authorization questions, that partner can help you bring in the right immigration counsel alongside them.
