Which document outlines the employment eligibility verification process?

Form I-9 is the document specifically designed to outline the employment eligibility verification process in the United States. This form is required by the U.S. Citizenship and Immigration Services (USCIS) to verify the identity and employment authorization of individuals hired for employment in the U.S. Employers must complete the Form I-9 for every new hire and maintain it in their records as proof that the employee is authorized to work.

The form requires employees to provide certain identification documents, which could include a U.S. passport, a permanent resident card, or other government-issued IDs that serve to confirm both identity and employment eligibility. This process ensures compliance with immigration laws and helps prevent the hiring of unauthorized workers.

In contrast, the other options serve different purposes: Form W-2 is used for reporting wages and tax withheld to employees and the IRS, Form 940 is an Employer's Annual Federal Unemployment (FUTA) Tax Return, and Form W-4 is used by employees to indicate their tax situation to their employer. Each of these forms plays an important role in payroll and tax reporting, but none pertain specifically to verifying employment eligibility.
