Individual Taxpayer Identification Number

An ITIN is a tax processing number issued by the IRS to individuals who are required to have a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security Number (SSN). If you are a non-U.S. citizen who needs to file a U.S. tax return, open a U.S. bank account, or conduct business in the United States, you likely need an ITIN.
