What is the primary purpose of the W-7 form?

The primary purpose of the W-7 form is to request an Individual Taxpayer Identification Number (ITIN). This form is specifically designed for individuals who need an identifying number for tax purposes but are not eligible for a Social Security number. This often includes non-resident aliens, their spouses, and dependents. By filling out the W-7, individuals can establish their identity for tax reporting and compliance even if they don't have a Social Security number.

The other options reflect different IRS forms and processes: reporting wages typically involves forms such as the W-2; an Employer Identification Number (EIN) is requested through a different application; and confirming tax payments does not relate to this particular form. Understanding the role of the W-7 is important for managing tax obligations and ensuring compliance for those who may not have direct access to standard identifying numbers.
