What is the title of the Federal form that job applicants must complete to prove their legal ability to work in the U.S.?

The Federal form that job applicants are required to complete to demonstrate their legal eligibility to work in the United States is known as the I-9 form. This form is crucial as it verifies an employee's identity and employment authorization. Upon hire, employees must present valid documents that establish both their identity and their right to work, which are then documented on the I-9 form.

The form is a requirement under the Immigration Reform and Control Act of 1986, which mandates that employers ensure their employees are legally permitted to work in the country. Completing the I-9 form is a critical step in the employment process, as failure to do so can lead to legal penalties for the employer.

The other forms listed serve different purposes. For instance, a W-2 is used to report wages for tax purposes, while a 1099 is used to report income who are self-employed or for contract work. Form 1040 is an individual income tax return. Each of these forms plays a role in the financial and tax management process but does not pertain to employment eligibility verification like the I-9 does.
