Who needs an ITIN?IRS issues ITINs to foreign nationals and others who have federal tax reporting or filing requirements and do not qualify for SSNs. A non-resident alien individual not eligible for a SSN who is required to file a U.S. tax return only to claim a refund of tax under the provisions of a U.S. tax treaty needs an ITIN. Other examples of individuals who need ITINs include:
• A nonresident alien required to file a U.S. tax return
• A U.S. resident alien (based on days present in the United States) filing a U.S. tax return
• A dependent or spouse of a U.S. citizen/resident alien
• A dependent or spouse of a nonresident alien visa holder.
How do I know if I need an ITIN?
If you do not have a SSN and are not eligible to obtain a SSN, but you have a requirement to furnish a federal tax identification number or file a federal income tax return, you must apply for an ITIN.
If you have an application for a SSN pending, do not file Form W-7. Complete Form W-7 only if the Social Security Administration (SSA) notifies you that a SSN cannot be issued.
To obtain a SSN, see Form SS-5, Application for a Social Security Card. To get Form SS-5 or to find out if you are eligible to obtain a SSN, go to Social Security Administration or contact a SSA office. By law, an alien individual cannot have both an ITIN and a SSN.
IRS processes returns showing SSNs or ITINs in the blanks where tax forms request SSNs. IRS no longer accepts, and will not process, forms showing "SSA", 205c", "applied for", "NRA",& blanks, etc.
How do I apply for an ITIN?
Use the latest revision of Form W-7, Application for IRS Individual Taxpayer Identification Number to apply. Attach a valid federal income tax return, unless you qualify for an exception, and include your original proof of identity or copies certified by issuing agency and foreign status documents.
Because you are filing your tax return as an attachment to your ITIN application, you should not mail your return to the address listed in the Form 1040, 1040A or 1040EZ instructions. Instead, send your return, Form W-7 and proof of identity and foreign status documents to:
