Why Employers Choose a Third-Party I-9 Auditor

Here’s why companies outsource:

Faster, unbiased compliance review using DHS/ICE standards.
Internal teams lack time—audits that take HR months are completed in days.
Find issues HR teams miss, including document mismatches, duplicates, and incorrect reverifications.
Consolidate paper, digital, and legacy I-9s into one structured audit process.
Prepare for audits, M&A, or due diligence with professional remediation plans and risk scoring.
Demonstrate good-faith compliance to regulators and legal teams.

Most HR teams don’t have the time or specialized expertise to complete a full, compliant I-9 audit. A third-party auditor gives employers a faster, more accurate, and legally defensible review.

A third-party audit removes uncertainty, reduces risk, and ensures your I-9s are truly audit-ready—before an inspector ever asks for them.

“After switching from our basic HRIS form-filler to i9 Intelligence, our agricultural enterprise achieved perfect I-9 compliance across all our growing operations. Their system automatically alerts us when returning seasonal workers need reverification.”

Michael Rodriguez, HR Director, Western Agricultural Producers

“The API integration with i9 Intelligence has made a huge difference for our team. Every new hire in the U.S. now receives the same communication and follows a consistent, compliant process pre-day one. It’s taken a lot of the manual work and guesswork off our plate. Knowing our I-9s are standardized and audit-ready gives us real peace of mind.”

Kim Carone, HR Service Delivery Manager, McCain Foods

I-9 Audit FAQs

What is included in an I-9 audit?

An I-9 audit includes a full review of every Form I-9 in your workforce—active and terminated—checking Section 1, Section 2, and Supplement B for accuracy, timeliness, completeness, and documentation consistency. It also includes payroll-to-I-9 matching, retention/purge analysis, duplicate form detection, and a comprehensive audit report with clear remediation steps.

How long does an I-9 audit take?

Most audits take 5–15 business days, depending on workforce size, onboarding complexity, and whether documents are stored electronically or in paper files. Large, multi-location or high-turnover employers may require additional time, but our team works significantly faster than internal reviews.

Can you audit paper I-9s, electronic I-9s, or both?

Yes. We offer a fully managed remote I-9 verYes. We audit paper I-9s, electronic I-9 files from any HRIS, digital exports, and legacy/migrated records. If your documents are spread across multiple systems—or stored inconsistently—we consolidate and review them in a unified audit processification service for public agencies and contractors.

Do you review supporting documents like passports or EADs?

Yes. If supporting document images are available, we compare them against the Section 2 entries for accuracy, expiration dates, document type, and list category compliance. This is one of the most common areas where onboarding errors occur.

What is payroll-to-I-9 reconciliation?

Payroll-to-I-9 reconciliation matches your active payroll roster to your active I-9 files to identify missing or incomplete forms. Missing I-9s are one of the highest-risk findings in ICE audits, often resulting in substantial fines or workforce eligibility concerns.

Can you identify duplicate or conflicting I-9s?

Yes. We flag duplicate records, conflicting document information, mismatched citizenship/immigration status entries, and incorrect reverifications—all of which can trigger audit scrutiny if left uncorrected.

Do you help determine which I-9s should be retained or purged?

Yes. Our audit includes a full retention and purge analysis using the federal rule (3 years after hire or 1 year after termination, whichever is later). Correct purging reduces long-term liability and is commonly overlooked by employers.

How does an I-9 audit help prepare for an ICE inspection?

Our audit uses evaluation criteria aligned with ICE audit standards, giving you a realistic picture of what an investigator would find. Correcting errors before an NOI (Notice of Inspection) dramatically reduces financial penalties and operational disruption.

Do you work with multi-location or high-turnover employers?

Absolutely. These employers often have the largest compliance gaps due to inconsistent onboarding practices. Our audit identifies patterns across locations and helps standardize I-9 execution across your organization.

Is an I-9 audit useful for M&A, due diligence, or investor reviews?

Yes. Buyers, investors, and attorneys frequently request I-9 compliance validation. An audit helps you avoid surprises during diligence and prevents delays or valuation impacts. We regularly support pre-M&A audits and private equity/VC reviews.
