You should submit a completed Form W-7, Application for IRS Individual Taxpayer Identification Number, and all required identification documents to the IRS. No tax return is required for a renewal application, however if you have a filing requirement you should file the return with the renewing application to prevent a delay in your refund. All family members who were issued an ITIN may submit a Form W-7 at the same time. Be sure to attach all required identification documents as indicated in the Revised Applications Standards. Only originals of identification documents or certified copies of the documents from the issuing agency will be accepted. See Frequently Asked Questions regarding ITIN expirations. Where do I apply to renew my ITIN? Option 1 Mail your W-7, proof of identity and foreign status documents to: Internal Revenue Service Austin Service Center ITIN Operation P.O. Box 149342 Austin, TX 78714-9342 We’ll return your identification documents within 60 days. Send your application to us early to avoid delays in processing your next tax return. 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 us your original identification documents. Option 3 Make an appointment at a designated IRS Taxpayer Assistance Center that authenticates W-7 documents. This also prevents you from having to mail us your original identification documents. After processing, the IRS will issue your ITIN assignment notice through the mail.
