What is an ITIN?
An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the IRS for individuals who are not eligible for a Social Security Number (SSN) but need to file a U.S. tax return or meet other tax reporting requirements.

You may need an ITIN if you are:
A nonresident who needs to file a U.S. tax return
A spouse or dependent of a U.S. taxpayer
A foreign investor with U.S. income (such as rental or partnership income)
Required to file Form W-7 with your tax return
