If you are a nonresident alien or a foreign national who is required to file tax returns in the United States, you will need an Individual Taxpayer Identification Number (ITIN). An ITIN is a tax processing number that is issued by the Internal Revenue Service (IRS) to those who are not eligible for a Social Security Number (SSN). In this article, we will provide you with the information and guidance you need to obtain your ITIN number.

A Step-by-Step Guide to Getting an ITIN Number

To obtain an ITIN number, you will need to provide documentation that proves your identity and foreign status. The following is a step-by-step guide to help you through the process:

Step 1: Obtain the Necessary Documentation

Before filling out the application form, you will need to obtain the appropriate documentation. This includes a completed Form W-7, which is the application form for an ITIN. You will also need to provide proof of your foreign status and identity, such as a passport, national ID card, or other government-issued ID. If you are filing a tax return and are claiming a tax treaty benefit, you may also need to provide additional supporting documentation.

Step 2: Fill Out the Application Form

Once you have gathered all the necessary documentation, you will need to fill out Form W-7. Be sure to read the instructions carefully and provide accurate and complete information. If you are unsure about any part of the form, seek help from a tax professional or the IRS.

Step 3: Send the Application Form and Documentation to the IRS

After completing Form W-7, you will need to mail the form and your supporting documentation to the IRS. Be sure to send the application via certified mail to ensure that it is received by the IRS. You can also visit an IRS Taxpayer Assistance Center to hand in your application in person.

Step 4: Wait for the ITIN Number to be Issued

After submitting your application, you will need to wait for the IRS to process it. This can take up to 11 weeks, depending on the time of year. Once your ITIN number has been issued, it will be mailed to you via postal mail.
