Answers to Common Questions

What is an ITIN?
It is a number for you to use on federal tax documents.

Who needs an ITIN?
A non-citizen who has to file a federal tax return or a tax reporting document and does not qualify for an SSN needs an ITIN.

What is correct documentation?
In general, correct documentation is unexpired and has your photograph. It has the same name on it as on your application and tax return. It is from an organization authorized to issue it. The following documents can meet these conditions:

  • a passport
  • a visa (issued by the U.S. Department of State)
  • a civil birth certificate
  • a national, U.S. state, or military identification document
  • a U.S. or foreign driver’s license
  • a U.S. Citizenship and Immigration Services Photo ID
  • a foreign voter registration document or military card
  • U.S. school records (for dependents only)
  • U.S. medical records (for dependents only)

Foreign records must be from a country recognized by the U.S. State Department.

What are the special requirements for school and medical records?
They must be less than one year old. They must be for dependents younger than 18.

How much time do I have to reply?
You have 45 days from the date of your notice to reply.

What happens if I don't reply?
We will reject your application. You'll have to submit a new application for an ITIN.

Should I call you with my reply or mail it to you?
Mail your reply to us at the address on the notice.

What happens to my tax return if you reject my application?
We'll process your return without an ITIN. You'll need to reapply for an ITIN and attach a copy of the return to your application to get a refund.

I sent you documents when I applied for an ITIN. When will you return them?
We'll return your documents within 60 days after we've processed your application.
