How to Write Form W7 Application for IRS Individual Taxpayer Identification Number

Before anything, let’s talk about what Form W7 is. 

The ITIN stands for Individual Taxpayer Identification Number. This is a tax processing number that contains nine digits. Through it, non-citizens can file a tax return to the IRS. 

These are the common reasons why an ITIN is needed:

• If you don’t have an SSN and you’re not eligible to get one
• You need to file a federal tax return or get a federal TIN

The good news is that applying for an ITIN isn’t a complicated process. You simply need to submit Form W7 to get your application started. Here are the steps to Form the W7 creation process:

1. Identify why you need an ITIN

Will you be applying for a new ITIN? Or do you need to renew an existing ITIN that is about to expire? The form contains various reasons why you are filling out the form. Some common causes include the following:

• You are a non-resident who needs to get an ITIN so you can claim a tax treaty benefit.
• You are a non-resident who needs to file a US tax return.
• You are a US resident (based on the days you are present in the US). And you need to file a tax return.
• You are either a dependent or the spouse of a US citizen.
• You are a non-resident student, professor, or researcher who needs to claim an exception or file a tax return.
• You are a spouse or dependent of a non-resident alien who is holding a US visa. 

Once you belong in any of these categories, you can proceed with completing the form. 

2. Provide your necessary information

The usual information that will be required in form W7 includes the following:

• Your name
• Your mailing address
• Your foreign (non-US) address
• Your birth information
• Other necessary details (country of citizenship, supporting documentation, and others)
• Your signature

Make sure to include these details when you’re writing Form W7 so that it can be processed right away.
