Individual Taxpayer Identification Number (ITIN) Application Guide

Select your Language


General Information: Individual Taxpayer Identification Numbers were created for foreign investors and visitors who owe taxes but are not eligible for a Social Security number. However, recently a large number of undocumented aliens have obtained ITINs, which enable them to legally file taxes in the United States, even if they lack the appropriate immigration status. The Individual Taxpayer Identification Number (ITIN) is a tax number issued by the IRS (Internal Revenue Service) and it is not related to the USCIS or the Social Security Administration. The ITIN is only issued for tax purposes. An Individual Taxpayer Identification Number (ITIN) does not provide the right to work or live in the United States.

Application Requirements: The IRS issues ITINs to individuals who are not able to obtain a Social Security Number. The requirements for obtaining an ITIN are different than other U.S. government applications, as the applicant's immigration status is not verified and the applicant does not have to meet in person to file the application. The supportive documents submitted are not validated outside the tax system. The IRS has their own set of rules and regulations, and it is not related to the USCIS. Only non-U.S. citizens can apply for an Individual Taxpayer Identification Number. Individuals who already have a valid Social Security Number should not apply for an ITIN, as it is not needed and it is not allowed to have both a Social Security Number and a ITIN. Individuals who have a valid Social Security Number should file taxes using the Social Security Number, not an ITIN.
