What Is an ITIN?
An ITIN (Individual Taxpayer Identification Number) is a 9-digit tax ID issued by the IRS to individuals who are not eligible for a Social Security Number but need to meet US tax obligations. It allows foreign nationals, non-residents, and others to interact with the US tax system.
| ITIN | SSN | |
|---|---|---|
| Purpose | Tax reporting only | Employment & tax |
| Eligible for | Individuals without an SSN | US citizens, residents, workers |
| Work auth | Does not authorize work in the US | Used for employment purposes |
| Held together | Cannot hold ITIN + SSN | Replaces ITIN when issued |
Why You Might Need an ITIN
If you're operating in the US but don't have a Social Security Number, an ITIN opens doors that would otherwise be closed.
File US Tax Returns
If you have US tax reporting obligations, an ITIN helps you file the required federal tax returns properly.
PayPal & Payment Verification
Payment platforms may request tax ID verification before allowing smoother account use and higher transaction limits.
Open a US Business Bank Account
Many US banking providers ask for tax identification during verification, especially for non-US applicants.

Common Questions
Quick answers to the questions we hear most often about ITIN.
An ITIN (Individual Taxpayer Identification Number) is a 9-digit number issued by the IRS to people who are not eligible for a Social Security Number but need to comply with US tax laws. It always begins with the number 9 and is used exclusively for tax filing purposes.
Non-US residents who own a US LLC, foreign nationals with US-source income, online entrepreneurs using US payment platforms, and anyone who must file a US tax return but is ineligible for an SSN may need an ITIN. It's also useful for banking and payment verification purposes.
The IRS typically processes ITIN applications within 7 to 11 weeks when submitted correctly. Processing times may be longer during peak tax season (January–April). Errors or missing documents can add several weeks to the timeline — which is why proper preparation matters.
You'll typically need a completed Form W-7, a valid passport or other government-issued ID proving foreign status, and a federal tax return or qualifying tax document establishing your reason for needing an ITIN. Exact requirements vary based on your specific tax purpose.
Yes. ITINs that have not been used on a federal tax return for three consecutive years expire. Additionally, ITINs with middle digits 70–88, 90–99, and certain others have been subject to expiration under IRS rules. If your ITIN has expired, you'll need to submit a renewal application using Form W-7.
