Which form is used to obtain an Employer Identification Number?

The correct choice for obtaining an Employer Identification Number (EIN) is the form designated as Form SS-4. This form is specifically designed for businesses and entities to apply for an EIN, which is essential for identifying and managing tax obligations. The Form SS-4 requests information about the business, including the legal structure, purpose, and ownership details, which the IRS uses to issue the EIN.

The other forms listed serve different purposes. Form W-2 is used by employers to report wages paid to employees and the taxes withheld from them. Form 1040 is the individual income tax return form for reporting personal income. Form 1099 is utilized to report various types of income received by individuals who are not classified as employees, including freelance work or interest income. Each of these forms has its own specific function, making Form SS-4 the correct choice for acquiring an Employer Identification Number.
