Construction pairs multi-site crews and seasonal labor with genuine confusion over subcontractors and 1099 workers, and federal or federally-funded projects often carry a FAR E-Verify clause. That mix — real employees whose paperwork is scattered across job sites, plus an E-Verify obligation that's easy to miss — is exactly what auditors probe.
2026 penalty context: Form I-9 paperwork and substantive violations run about $288–$2,861 per form, and knowingly hiring or continuing to employ an unauthorized worker runs far higher — up to roughly $28,619 per worker. Because paperwork penalties are assessed per form, a high-volume employer can accumulate six-figure exposure from errors no one knew were there. In March 2026 ICE also moved several formerly-technical errors into the substantive (fineable) column.
What an I-9 audit surfaces for construction companies
The subcontractor/1099 blur
You don't complete I-9s for a bona fide independent contractor's workers — but misclassified workers who are really yours still need one, and 'we thought they were subs' is not a defense at audit.
Federal-contractor E-Verify
Projects with the FAR E-Verify clause require you to run E-Verify. Skipping enrollment or cases on a covered job is a gap auditors specifically look for.
Crews spread across sites
Forms completed in the field, stored in trucks or trailers, or split across superintendents go missing or get finished late — both common substantive findings.
Seasonal ramp-ups
Fast spring/summer hiring pushes Section 2 past the three-business-day deadline, and rehires get new forms when they shouldn't (or none when they should).
The correct way to fix what you find
Finding errors is only half of it — the fix has to be USCIS-correct, or it can create worse liability than the original mistake. The non-negotiable rules:
- Line through the incorrect entry, enter 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.
- Only the employee corrects Section 1; only the employer representative who examined the documents corrects Section 2.
- When a whole form or step was skipped, do it now, dated today, with a short signed memo explaining the timing.

Do I complete I-9s for my subcontractors' workers?
No — for a genuine independent contractor you don't complete I-9s for their employees. But if workers are misclassified and are really your employees, they need I-9s. When in doubt, treat classification carefully; ICE and DOL both scrutinize it.
We do some federal jobs — does E-Verify apply?
If your contract includes the FAR E-Verify clause, yes, and you generally must run E-Verify on the covered workforce. You can't create E-Verify cases retroactively, so fix the process going forward and document the remediation date.
Our I-9s are scattered across job sites — is that a problem?
It's a common source of missing and late forms. Centralize retained I-9s, run a self-audit against your active roster, and complete any missing form now — dated today, with a short signed memo — rather than backdating.
