What changed with I-9s in March 2026?

If you have not looked at your I-9s since March, now is the time. This article explains what changed, which mistakes are now expensive, and what to do about them this month.

What exactly changed?

ICE did not change the form. It changed the classification. The updated fact sheet moves common mistakes from the technical column to the substantive column, and it lists 28 categories of errors that count as substantive. There was no Federal Register notice, so many employers never heard about it. They will hear about it the first time an inspection turns a paperwork mistake into a fine.

The practical difference is simple. A technical error used to mean you had 10 days to correct it. A substantive error means ICE treats the form as noncompliant, and fines apply. The fine range runs $288 to $2,861 per form, and it is per form, not per error. One form with three mistakes is one fine, but three forms with one mistake each is three fines.

Which errors moved?

The errors that moved are the ordinary ones. A missing birthdate. A missing hire date. An undated Section 2. A Section 1 that was never signed. These are the mistakes a busy hiring manager makes on a Friday afternoon, and they used to be fixable. Now they are substantive on arrival.

The point is not that ICE got stricter about one detail. The point is that the whole pile of small mistakes now carries real money. If you have 50 employees and 20 forms have a moved error, that is 20 forms at $288 to $2,861 each. The low end is $5,760. The high end is $57,220. That is the math that makes an audit worth doing before an inspector does it for you.

What does a substantive error cost?

The fine range comes from the DHS inflation adjustment of January 2, 2025, under 8 CFR 274a.10. An OMB memo, M-26-11, cancelled the 2026 adjustment, so the 2025 figures remain in force through 2026. The range is $288 to $2,861 per form.

Fines are only part of the cost. An inspection pulls your team off real work for days. It creates a paper trail that follows you into the next inspection. And if the same mistakes show up again, the next round is worse. The cheapest I-9 problem is the one you find yourself.

What should you do this month?

Work through your I-9s in four steps.

1. Pull every I-9. Every current employee and every former employee whose retention period has not run out.
2. Check Sections 1 and 2 line by line. Look for the moved errors first: missing dates, missing signatures, an undated Section 2.
3. Correct mistakes the right way. Draw a line through the wrong entry, write the correct information, then initial and date the correction. Never backdate. Never white it out.
4. Write a short memo. One page that says what you checked, what you found, and what you fixed. Date it and keep it with the files. It shows the next inspector that you run a real process.

If you find a pattern, fix the process behind it. Most I-9 errors come from the same place: the form gets completed in a rush, by whoever is free, with no second look. A two-minute review by a second person at hire time prevents most of them.

What should I not do?

Do not backdate a correction. Do not ask an employee for more documents than the form requires. Do not re-verify a document you have already accepted unless the law asks you to. Each of these creates a new problem that is worse than the one you were fixing.

Do not panic either. The March change is serious, but it is a paperwork problem with a paperwork solution. Pull the forms, fix them properly, and document what you did.
