A Comprehensive Guide to ITIN Application: Requirements and Steps

Navigating through tax processes can be daunting, especially if you're a non-resident or a foreign entity conducting business or earning income in the United States. However, the Internal Revenue Service (IRS) has provisions in place to ensure that everyone, regardless of citizenship status, can comply with tax laws. One such provision is the Individual Taxpayer Identification Number (ITIN). In this guide, we'll walk you through the requirements and steps for obtaining an ITIN.

What is an ITIN? An ITIN is a nine-digit number issued by the IRS to individuals who are required to have a U.S. taxpayer identification number but are not eligible for a Social Security Number (SSN). It's primarily used for federal tax purposes and is issued regardless of immigration status, as both resident and non-resident aliens may have U.S. tax filing or reporting requirements.


Requirements for ITIN Application: Before starting the application process, it's essential to ensure you meet the eligibility criteria set by the IRS. The primary requirements include:

  1. You must have a federal tax reporting requirement or be filing taxes in the United States.
  2. You must not be eligible to obtain a Social Security Number (SSN).
  3. You need to submit a valid federal income tax return or another qualifying document to support your need for an ITIN.

Steps for ITIN Application: Once you've confirmed that you meet the eligibility criteria, you can proceed with the application process. Here are the steps involved:

  1. Obtain Form W-7: The IRS requires applicants to complete Form W-7, Application for IRS Individual Taxpayer Identification Number. You can download this form from the IRS website or request a copy by calling the IRS toll-free number.

  2. Gather Required Documentation: Along with Form W-7, you need to submit original identification documents or certified copies by the issuing agency. These documents must establish both your identity and foreign status. Acceptable documents include passports, national identification cards, birth certificates, and other forms of identification specified by the IRS.

  3. Complete Form W-7: Fill out Form W-7 accurately and completely. Ensure that all information provided matches the details on your supporting identification documents.

  4. Attach Supporting Documentation: Along with Form W-7, you must include original or certified copies of documents that establish your identity and foreign status. Be sure to review the instructions provided by the IRS to ensure you're submitting the correct documentation.

  5. Mail Your Application: Once you've completed Form W-7 and gathered all required documentation, mail your application to the address specified in the instructions. The IRS will process your application and return your documents once the ITIN is assigned.

  6. Wait for Processing: The processing time for ITIN applications can vary depending on the volume of applications received by the IRS. Generally, it takes about 7 to 11 weeks to receive your ITIN after the IRS receives your completed application.

  7. Receive Your ITIN: Once your application is processed and approved, the IRS will assign you an ITIN. You'll receive a letter from the IRS containing your ITIN along with any original documents you submitted.


 Obtaining an ITIN is a crucial step for individuals who need to fulfill their U.S. tax obligations but are not eligible for a Social Security Number. By understanding the requirements and following the steps outlined in this guide, you can successfully apply for an ITIN and ensure compliance with U.S. tax laws. If you have any questions or need assistance during the application process, consider seeking guidance from a tax professional or contacting the IRS directly.
