Which form that a new employee is required to complete confirms authorized work status?

The correct answer is B, the I-9 form. This form is essential for verifying an employee's identity and confirming their authorized work status in the United States. When a new employee is hired, they must complete the I-9 form, which requires them to provide documentation that proves both their identity and their eligibility to work. The employer is responsible for reviewing the documents provided by the new employee to ensure they meet the legal requirements.

In contrast, the W-2 form is used to report an employee's annual wages and taxes withheld, but does not pertain to work authorization. The W-4 form is related to the employee's tax withholding preferences and is not used for confirming work status. The 401(k) plan refers to a retirement savings plan, which is important for benefits management but has no relevance to verifying an employee's right to work. Understanding this distinction is vital in the context of an employee's onboarding process.
