The ITIN (Individual Taxpayer Identification Number) is a tax identification number issued by the Internal Revenue Service (IRS) in the United States. It’s essential for individuals who aren’t eligible for a Social Security Number (SSN) but need to meet their tax obligations in the U.S.

In this blog, we’ll explore in detail what the ITIN is, who needs it, how to get it, and how Prodezk can help you through the process.

1. What Is an ITIN?

An ITIN is a nine-digit number issued by the IRS to people who aren’t eligible for an SSN but need to comply with U.S. tax laws. This number allows non-residents, dependents of foreign nationals, and others without an SSN to fulfill their tax obligations, such as filing tax returns.

Key Features of the ITIN:

  1. 01For tax purposes only: The ITIN is exclusively for meeting U.S. tax laws . It does not authorize employment or provide Social Security benefits.
  2. 02Nine digits: ITINs follow the same nine-digit format as SSNs, typically starting with a "9."
  3. 03Issued by the IRS: The ITIN is directly issued by the IRS and is required for anyone who must file a tax return but doesn’t qualify for an SSN.
