What form is used to request an ITIN?

The correct form used to request an Individual Taxpayer Identification Number (ITIN) is Form W-7. This form is specifically designed for individuals who are not eligible for a Social Security number but need a taxpayer identification number for tax purposes.

Form W-7 requires the applicant to provide personal information, including their name, mailing address, and the reason for needing an ITIN. The ITIN is essential for filing federal tax returns, opening bank accounts, and fulfilling other financial reporting obligations.

In contrast, Form SS-4 is used to apply for an Employer Identification Number (EIN), which is required for businesses rather than individuals. Form W-2 is a wage and tax statement provided by employers to report wages paid and taxes withheld for employees, while Form 1040 is used by individuals to file their personal income tax returns. Thus, Form W-7 is uniquely suited for the specific purpose of obtaining an ITIN.
