Introduction

Form W-7, Application for IRS Individual Taxpayer Identification Number, is used by individuals who need an Individual Taxpayer Identification Number, commonly called an ITIN. An ITIN is a tax processing number used for certain federal tax purposes when an individual is not eligible to obtain a Social Security number.

Form W-7 may be used for an initial ITIN application or, when applicable, to renew an existing ITIN. The form is generally associated with individuals who have a federal tax purpose but do not qualify for a Social Security number.

What Is Form W-7?

Form W-7 is an application used to request an Individual Taxpayer Identification Number from the federal tax authority. The ITIN is used for federal tax reporting and processing purposes and does not generally provide employment authorization or establish eligibility for Social Security benefits.

The form collects identifying information about the applicant and information supporting the reason an ITIN is being requested. The requirements can vary depending on the applicant’s circumstances and the reason for the application.

Who Uses Form W-7?

Form W-7 may be used by individuals who have a federal tax filing or reporting requirement but are not eligible for a Social Security number. It may apply to certain nonresident or resident individuals, dependents, spouses, and other individuals who meet the applicable requirements.

Not every individual without a Social Security number needs an ITIN. An applicant generally needs to meet an applicable reason for obtaining an ITIN and provide the required documentation to support the application.

What Information Is Needed?

The information needed to complete Form W-7 generally includes the applicant’s name, mailing information, birth information, country of citizenship, and other identifying details. The applicant will also generally need to identify the reason for requesting or renewing an ITIN.
