Form I-9 Compliance in 2026: Essential Practices for U.S. Employers to Avoid Costly Penalties

Every employer in the United States is required to complete Form I-9 for each individual they hire, regardless of citizenship or immigration status. With increased government audits and higher potential fines, maintaining strong Form I-9 compliance is more important than ever for businesses of all sizes.

This NPZ update provides clear, practical guidance to help employers meet their obligations and avoid penalties.

1. Why Accurate Form I-9 Completion Matters

The Form I-9 verifies two things:

  1. The employee’s identity, and
  2. Their authorization to work in the United States.

U.S. Immigration and Customs Enforcement (ICE) regularly conducts audits to check for errors, missing forms, or outdated documents. Even first-time technical violations can result in fines, and repeated or serious violations may lead to more severe penalties.

2. Section 1: Completed by the Employee

The employee must complete and sign Section 1 no later than the first day of work.

Key employer responsibilities:

  • Ensure the employee completes Section 1 on time
  • Never fill out Section 1 for an employee
  • If using E-Verify, the employee must provide their SSN, even if they choose different documents for Section 2

3. Section 2: Completed by the Employer

Employers must complete Section 2 within three business days of the employee starting work for pay.

Employers must:

  • Physically examine original, unexpired documents
  • Review documents from the Lists of Acceptable Documents
  • Accept only the minimum required documentation
  • Avoid steering or suggesting which documents the employee should present

Employers may not:

  • Accept more documents than required
  • Refuse valid documents
  • Use the Spanish version of Form I-9 unless authorized (e.g., Puerto Rico)

4. Section 3: Reverification When Required

Reverification is required only when an employee’s work authorization has an expiration date.

Employers must:

  • Track expiration dates of temporary work authorization
  • Request updated proof of continued authorization
  • Reverify before the current authorization expires

U.S. citizens and permanent residents are not subject to reverification.

5. Understanding E-Verify

E-Verify compares Form I-9 data with records from the Department of Homeland Security and the Social Security Administration.

If your company participates:

  • Create an E-Verify case no later than the third business day after the employee starts work
  • Follow the required steps if the system issues a Tentative Nonconfirmation (TNC)
  • Never take action against the employee until the process is resolved

6. Best Practices to Protect Your Business

To reduce risk and strengthen compliance, employers should:

Conduct Regular Internal Audits

Review existing I-9s for missing signatures, incorrect dates, or expired documentation.

Use Standardized Procedures

Ensure HR teams follow the same steps for every hire.

Train HR Staff Regularly

Policies change. Regular training reduces errors.

Store I-9s Properly

Forms must be retained for the required period and made available during inspections.

Seek Legal Guidance When Needed

If there is uncertainty about how to complete or correct a Form I-9, employers should seek help before a mistake becomes a liability.

Conclusion

Form I-9 compliance is an important part of every employer’s legal responsibility. By completing each section properly, monitoring reverification deadlines, and maintaining accurate records, businesses can reduce their risk of penalties and ensure compliance with federal law.
