What is the minimum length of time an employer must keep a Form I-9 on file?

The Form I-9, which is used to verify an employee's identity and employment authorization in the United States, has specific requirements regarding record retention. An employer must retain each employee's completed Form I-9 for three years after the date of hire or for one year after the employee's termination, whichever is longer. Therefore, the minimum length of time an employer is required to keep the Form I-9 on file aligns perfectly with the three-year duration.

Understanding the retention period is crucial for employers to remain compliant with immigration laws and avoid potential fines for improper record keeping. This duration ensures that the employer has the necessary documentation to prove an employee's eligibility to work throughout their employment and for a period following their departure, which is significant for audits and legal protections regarding employment verification.
