                  Individual Taxpayer Identification Number (ITIN)

How To Apply:

Use the latest revision of Form W-7, Application for IRS Individual Taxpayer Identification Number.  Attach a valid Federal Income Tax return unless you qualify for an exception, and include your original or certified proof of identity documents.  Since you are filing your tax return as an attachment to your ITIN application, you should not mail your return to the address listed in the Form 1040, 1040A or 1040EZ instructions.  Instead, send your tax return, Form W-7 and proof of identity documents to:

           Internal Revenue Service

           Austin Service Center

           ITIN Operation

           P.O. Box 149342

           Austin, TX 78714-9342

When To Apply:

 You should complete Form W-7 as soon as you are ready to file your federal income tax return, since you need to attach the return to your application.  If you meet one of the exceptions and do not need to file a return, submit Form W-7, along with the documents required to meet your purpose for needing an ITIN, as soon as possible after you determine that you are covered by that exception.

Expected Turnaround Time:

 If you qualify for an ITIN and your application is complete, you will receive a letter from the IRS assigning your tax identification number usually within four to six weeks.  The IRS has changed from an ITIN card to an authorization letter to avoid any possible similarities with a Social Security Number card.  If you have not received your ITIN or other correspondence six weeks after applying, you may call the IRS to find out the status of your application.

For Help:

You may call the IRS toll-free at 1(800) 829-1040 for information and help in completing your Form W-7 and your tax return, or to check on the status of your application six weeks after submitting Form W-7.

You may also use an IRS-authorized Acceptance Agent.  This is an individual, business or organization (college, financial institution, accounting firm, etc.) authorized by the IRS to assist individuals in obtaining ITINs.  Certifying Acceptance Agents review applicants’ documentation, complete a certificate of accuracy, and forward the certificate and application to the IRS for processing.
