ITIN (Individual Taxpayer Identification Number) – Frequently Asked Questions
What is an ITIN and why do I need one?
An ITIN (Individual Taxpayer Identification Number) is a tax processing number issued by the IRS for individuals who are not eligible for a Social Security Number (SSN). You need an ITIN to file U.S. taxes, open a bank account, or comply with federal tax laws.
Who qualifies to apply for an ITIN?
You may qualify for an ITIN if you are a non-resident individual, dependent, or spouse who is required to file — or be listed on — a U.S. tax return but are not eligible to obtain a Social Security Number (SSN). The ITIN is specifically designed to help individuals meet U.S. tax reporting requirements when an SSN is not available.
What is the processing time to receive an ITIN?
The IRS typically processes ITIN applications within 6 to 12 weeks, depending on application accuracy and overall IRS workload. Submitting complete and error-free documents can help avoid delays. Applying through a Certified Acceptance Agent (CAA) may also help streamline the process.
How to get an ITIN Number for a non‑resident?
- Basic steps
- Complete Form W‑7
- This is the IRS Application for an Individual Taxpayer Identification Number. It’s required to apply for an ITIN.
- Gather required identity and foreign‑status documents
- A passport is the strongest document because it alone can prove both identity and foreign status. If you use something else, you must submit at least 2 other documents that, together, prove identity and foreign status.
- Provide a federal tax purpose
- Along with W‑7, you usually submit a U.S. federal tax return or other documentation showing the federal tax reason for needing an ITIN. This proves the need for the ITIN.
- Submit the application
- Mail the W‑7 and documents to the IRS (with original or properly certified copies of supporting documents), or
- Submit through a Certifying Acceptance Agent (CAA) either in the U.S. or abroad, or
- If in the U.S., you could schedule an appointment at an IRS Taxpayer Assistance Center.
- Complete Form W‑7

How to apply for an ITIN from Pakistan?
If you are in Pakistan (or any country outside the U.S.), the process is essentially the same, but you’ll typically go through one of these routes:
1. Apply by mail to the IRS with Form W‑7
- Prepare W‑7, supporting documents (passport or other approved documents), and the relevant tax return or proof of purpose.
- Mail everything to the IRS exactly as instructed (originals or certified copies are needed). This works from abroad.
2. Use a Certifying Acceptance Agent (CAA) abroad
- A CAA located outside the U.S. can help you prepare the W‑7, check your documents, and certify them so you don’t have to send originals to the IRS.
- This is often the most convenient method when applying from Pakistan, because CAAs handle document verification and help ensure the application is complete before submission. The IRS allows CAAs to assist both in the U.S. and abroad.
3. If you later visit the U.S
- Optionally, you could apply in person at an IRS Taxpayer Assistance Center, but this is only realistic if you have plans to be in the U.S. and can schedule an appointment. Otherwise, mail or CAA is the practical route.
Is an ITIN the same as a Social Security Number (SSN)?
No, an ITIN (Individual Taxpayer Identification Number) is not the same as a Social Security Number (SSN).
An ITIN is a tax processing number issued by the IRS to certain non-resident and resident aliens, as well as their spouses and dependents, who are not eligible for an SSN.
Unlike an SSN, an ITIN is used strictly for federal tax reporting purposes and does not authorize employment or provide eligibility for Social Security benefits.
Can a non-U.S. resident apply for an ITIN?
Yes, non-U.S. citizens and non-residents who are not eligible for a Social Security Number (SSN) can apply for an Individual Taxpayer Identification Number (ITIN). The ITIN is issued by the IRS for federal tax reporting purposes. It is commonly required by foreign business owners, investors, and individuals who need to file U.S. tax returns.
What is the difference between an SSN, EIN, and ITIN?
An SSN (Social Security Number) is issued to U.S. citizens and eligible residents for employment and personal tax purposes.
An EIN (Employer Identification Number) is issued to businesses for tax filing, hiring employees, and opening business bank accounts.
An ITIN (Individual Taxpayer Identification Number) is issued to individuals who are not eligible for an SSN but need to comply with U.S. tax laws.
Each number serves a different purpose, and choosing the correct one depends on your residency status and business structure.
