The Importance of Form I-9 Retention
The U.S. Citizenship and Immigration Services (USCIS) mandates that employers must retain a completed Form I-9 for all current employees. You cannot shred or discard an I-9 while an employee is actively working for you.
The challenge arises when an employee leaves the company. Employers are required to keep the form for a specific duration after termination to allow for potential audits by Immigration and Customs Enforcement (ICE). Keeping forms longer than legally required exposes a company to unnecessary data privacy risks, while destroying them too early violates federal law.
The 3-Year / 1-Year Retention Rule Explained
When an employee's employment is terminated, federal regulations require you to calculate two distinct dates and retain the Form I-9 until the later of those two dates has passed.
First, you must calculate 3 years after the employee's original date of hire. Second, you must calculate 1 year after the employee's date of termination.
You must compare these two dates. The date that occurs furthest in the future is the earliest legal date you can purge or destroy the employee's Form I-9.
- Calculation A: Date of Hire + 3 Years
- Calculation B: Date of Termination + 1 Year
- Retention End Date: The later of Calculation A or Calculation B.
Worked Example: Calculating the Purge Date
Let's look at a practical example. Suppose you hired an employee on January 15, 2021. They worked for exactly two years and were terminated on January 15, 2023.
Calculation A (Hire + 3 Years) results in January 15, 2024. Calculation B (Termination + 1 Year) results in January 15, 2024. In this unique scenario, both dates are identical, so the purge date is January 15, 2024.
Now consider a short-term employee hired on May 1, 2023, and terminated on August 1, 2023. Calculation A (Hire + 3 Years) is May 1, 2026. Calculation B (Termination + 1 Year) is August 1, 2024. Because the 3-year hire date is later, you must keep the form until May 1, 2026.
Best Practices for Storing I-9 Forms
To simplify audits and prevent accidental purges of active employee records, HR departments should never store Form I-9s inside standard employee personnel files.
Instead, I-9s should be kept in a centralized location. Best practice dictates maintaining three distinct folders or digital directories: one for Active Employees, one for Terminated Employees awaiting their purge date, and a secure disposal process for those whose retention period has expired.
Frequently asked questions
What is the penalty for failing to retain a Form I-9?
Fines for substantive paperwork violations, such as failing to produce an I-9 during an ICE audit because it was destroyed prematurely, can range from hundreds to thousands of dollars per missing form.
Do I need to keep copies of the identity documents (like passports or driver's licenses)?
Keeping copies of verification documents is optional for most employers (unless participating in E-Verify). However, if you choose to keep copies, you must do so consistently for all employees and retain them alongside the I-9 form for the same duration.
Can I store I-9 forms digitally?
Yes, USCIS allows employers to store Form I-9 electronically, provided the electronic storage system includes controls to prevent unauthorized access, alteration, or deletion of the records.
What should I do on the exact purge date?
Once the required retention date has passed, you should securely destroy the physical form (e.g., cross-cut shredding) or permanently delete the digital file to minimize data liability.
