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. Can I use an ITIN for identification? No. It is only for tax purposes. It is not for non-tax purposes. What’s the difference between an ITIN and an SSN? You can use an ITIN like an SSN on federal tax documents, but it doesn’t share other properties of an SSN. Receiving an ITIN therefore doesn’t entitle you to collect Social Security benefits, entitle you to EIC, or alter your immigration status, among other differences. Can I claim the Earned Income Tax Credit (EITC) when I file my tax return? No, individuals filing a tax return with an ITIN can't claim the EITC. What happens to my ITIN if I become a U.S. citizen? You can get an SSN when you become a U.S. citizen. What should I do if I get an SSN? Use your SSN. Stop using your ITIN. Let us know you have an SSN so we can change our records.
