You will only file a tax return to the address above once, when you file Form W-7 to get an ITIN. In subsequent years, when you have an ITIN, you will file your tax return as directed in the form instructions.
If you will need your original documents for any purpose within 14 weeks of submitting your ITIN application, you may wish to apply in person at an IRS Taxpayer Assistance Center or CAA. You may also choose to submit certified copies of documents from the issuing agency instead of original documents. Original documents you submit will be returned to you at the mailing address shown on your Form W-7. You don’t need to provide a return envelope. Applicants are permitted to include a prepaid Express Mail or courier envelope for faster return delivery of their documents.
Option 2
Apply for an ITIN in-person using the services of an IRS-authorized Certifying Acceptance Agent. This will prevent you from having to mail your proof of identity and foreign status documents.
Option 3
Make an appointment at a designated IRS Taxpayer Assistance Center. This will also prevent you from having to mail your proof of identity and foreign status document.
After processing, the IRS will issue your ITIN through the mail.
