Employers must retain completed I-9 forms for 3 years after the date of hire OR 1 year after employment termination, whichever is later. This means an employee hired on January 1, 2023, and terminated on June 30, 2024, requires I-9 retention until January 1, 2026 (3 years from hire date), not July 1, 2025 (1 year from termination). The "whichever is later" rule ensures long-term employees who leave before the 3-year mark still have their I-9 retained for 1 year post-termination, while short-term employees who leave within months of hire still have their I-9 retained for the full 3 years from hire date. Early destruction or loss of I-9 forms before the required retention period expires triggers automatic penalties of $288 to $2,861 per missing form during ICE audits, even if the original I-9 was completed correctly.

The retention requirement applies to all I-9 forms regardless of whether the employee was full-time, part-time, seasonal, or temporary, and includes all supporting documentation such as copies of identity documents (if the employer chose to retain them), reverification records (Section 3), and any notes or correspondence related to the I-9 completion process. Employers must store I-9 forms separately from personnel files and ensure they are readily accessible for ICE inspection—typically within 3 business days of receiving a Notice of Inspection. Digital storage is permitted if the system maintains data integrity, prevents unauthorized alterations, and can produce readable paper copies on demand. Many employers struggle with I-9 retention compliance due to poor tracking systems that don't automatically calculate retention deadlines or flag forms eligible for destruction.
