Nonresident aliens who need to file a U.S. tax return may also need an Individual Taxpayer Identification Number if they are not eligible for a Social Security number. The process usually starts with Form W-7, a federal tax return, and documents that prove identity and foreign status. This guide explains how to apply for an ITIN before filing a U.S. tax return and when in-person support from a Certified Acceptance Agent in Pittsburgh may help.
How Do Nonresident Aliens Apply for an ITIN Before Filing a U.S. Tax Return?
Nonresident aliens generally apply for an ITIN by completing Form W-7 and submitting it with the required tax return and supporting documents. The IRS says an ITIN application package includes Form W-7, a U.S. federal income tax return such as Form 1040 or Form 1040-NR, and documents proving foreign status and identity. (IRS)
This means the ITIN process is usually tied to an actual federal tax purpose. A person should not apply for an ITIN simply because they want a U.S. identification number. The IRS explains that an ITIN is for individuals who need a taxpayer identification number for U.S. federal tax purposes but do not have and are not eligible for an SSN. (IRS)

What Forms Are Usually Needed for a Nonresident Alien ITIN Application?
The main form needed for a nonresident alien ITIN application is Form W-7. The IRS states that Form W-7 is used to apply for an ITIN or renew an existing ITIN. (IRS)
In many cases, the application package also includes a federal tax return. For nonresident aliens, this may be Form 1040-NR, which is the U.S. Nonresident Alien Income Tax Return. The IRS identifies Form 1040-NR as the return used by certain nonresident aliens with U.S. tax filing needs. (IRS)
A practical application package may include:
- Completed Form W-7
- Completed Form 1040-NR or another required federal return
- Passport or other acceptable identity document
- Foreign status documentation, if needed
- Any tax forms connected to the filing reason
- Prior ITIN notices, if the applicant is renewing or correcting an issue
Applicants should make sure the name, date of birth, country of citizenship, and document details match across the form, return, and supporting documents. Small inconsistencies can create processing delays.
Can Form W-7 Be Submitted With a Tax Return?
Yes. In many first-time ITIN cases, Form W-7 is submitted with the tax return that requires the ITIN. The IRS says applicants should complete Form 1040 or Form 1040-NR, leave the SSN area blank for each ITIN applicant, and attach Forms W-7 for applicants to the front of the tax return. (IRS)
There are some exceptions where a tax return may not need to be attached, but the applicant must meet the exception requirements. The IRS notes that in certain cases, applicants may meet an exception to the filing requirement. (IRS)
Because the W-7 and tax return often move together, it is important to review the package before sending it. A missing form, unsigned return, wrong taxpayer category, or incomplete supporting document can slow the process. For a more focused explanation, see Can you submit Form W-7 with Form 1040-NR?
What Should Nonresident Aliens Do Before an ITIN Appointment?
Before an ITIN appointment, nonresident aliens should gather the paperwork connected to their tax purpose and review whether they are applying for a new ITIN or renewing an existing one. The IRS says applicants applying in person may use an IRS Taxpayer Assistance Center with ITIN services, a VITA site with ITIN services, a Certifying Acceptance Agent, or an Acceptance Agent. (IRS)
Before the appointment, prepare:
- Completed or draft Form W-7
- Tax return or tax paperwork connected to the ITIN request
- Passport or other identity documents
- Foreign status documents, if applicable
- Any IRS letters or prior ITIN notices
- Questions about document review and next steps
The IRS explains that a Certifying Acceptance Agent can complete and review Form W-7, authenticate most supporting documents, return authenticated documents at the end of the appointment, mail the ITIN package, and work with the IRS to resolve application issues. (IRS)
