What Is an ITIN?
ITIN stands for Individual Taxpayer Identification Number. It's a 9-digit number issued by the Internal Revenue Service (IRS) for individuals who must file U.S. taxes but are not eligible for a Social Security Number.
ITINs are used only for federal tax purposes and always begin with the number 9 (e.g., 9XX-XX-XXXX).
Who Qualifies for an ITIN?
You may qualify for an ITIN if you fall under one of these categories:
- A non-resident alien filing a U.S. tax return
- A spouse or dependent of a U.S. citizen or resident
- A dependent or spouse of a visa holder
- A student, professor, or researcher in the U.S. with taxable income
- A foreign investor receiving U.S. income
- Anyone who must file taxes but cannot get an SSN
Even if you don't live in the U.S. full-time, if you earn U.S. income or have tax obligations, you might need an ITIN.
What Is an ITIN Number Used For?
An ITIN is mainly used for filing U.S. federal tax returns. However, it can also help in situations like:
- Claiming tax refunds (if eligible)
- Supporting visa or immigration paperwork
- Opening certain U.S. bank accounts
- Applying for mortgages or loans (in some cases)
- Identifying yourself in the U.S. tax system
It's important to note that an ITIN does not authorize work in the U.S. and cannot be used for Social Security benefits.
How to Apply for an ITIN
To get an ITIN number in the U.S., follow these general steps:
- Fill out IRS Form W-7
- Provide original or certified copies of identity documents (like a passport)
- Attach a valid federal tax return (unless an exception applies)
- Mail your documents to the IRS or apply through a certified acceptance agent
The process can take several weeks, so it's a good idea to start early—especially before the April tax deadline.
