Which form is used to prove you are legally eligible to work in the U.S.?

• A. W-4
• B. W-2
• C. 1040
• D. I-9

Answer: (D)

To prove you’re legally eligible to work in the U.S., the form used is the I-9, which verifies both your identity and your authorization to work. When you’re hired, you complete this form and present documents from approved lists (such as a passport, or a combination like a driver’s license and a Social Security card) to show who you are and that you’re allowed to work in the country. The employer then reviews those documents and keeps the I-9 on file, typically within a few days of hire. This process is separate from taxes: the W-4 handles how much federal tax to withhold, the W-2 reports earnings and taxes for the year, and Form 1040 is the annual tax return you file. So, the I-9 is specifically about employment eligibility verification.
