For many foreign nationals living or working in the United States, obtaining a Social Security Number (SSN) isn't possible. However, the IRS still requires tax compliance. That's where the Individual Taxpayer Identification Number (ITIN) comes in.
What is an ITIN?
An ITIN is a nine-digit tax processing number issued by the Internal Revenue Service (IRS). It is formatted like an SSN (XXX-XX-XXXX) but always begins with the number 9. It is available to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain, an SSN.
Primary Purpose: Tax Processing
The sole purpose of an ITIN is federal tax reporting. It allows individuals to comply with U.S. tax laws and provides a means to efficiently process and account for tax returns and payments.
Who Needs an ITIN?
You may need an ITIN if you fall into one of these categories:
- Non-resident aliens who need to file a tax return to claim a refund or report income.
- U.S. resident aliens (based on days present in the U.S.) who are filing a U.S. tax return.
- Dependents or spouses of U.S. citizens/resident aliens or non-resident alien visa holders.
What an ITIN Does NOT Do
It's important to understand the limitations of an ITIN:
- It does NOT authorize work in the U.S.
- It does NOT provide eligibility for Social Security benefits.
- It does NOT qualify a dependent for the Earned Income Tax Credit (EITC).
Conclusion
The ITIN is a critical tool for tax compliance for those ineligible for an SSN. It ensures that everyone earning income in the U.S. can fulfill their tax obligations.
