ITIN tax number, or Individual Taxpayer Identification Number is the nine digit number explicitly used for federal tax reporting in the United States. IRS (Internal Revenue Service) is responsible for issuing these numbers to individuals who are not eligible for the SSN (Social Security Number).

Purpose of ITIN Tax Number

As mentioned earlier, the sole purpose of ITIN tax number is efficient tax administration to deal with individuals’ tax returns and payments. Point to note is that an ITIN tax number does not give SSN benefits, EIC (Earned Income Credit) or changes your immigration status. A resident or nonresident, both can have an ITIN tax number as long as he/she has certain tax implications. Unlike the SSN which is only issued to the U.S. residents.

Who can apply?

There is a whole list of individuals who can or need an ITIN tax number such as:

  • A nonresident alien required to file a U.S. tax return
    • A U.S. resident alien (based on days present in the United States) filing a U.S. tax return
    • A dependent or spouse of a U.S. citizen/resident alien
    • A dependent or spouse of a nonresident alien visa holder etc.

Ways to Apply

There are three ways to apply for ITIN tax number. You either do it in-person, apply online or via CAA.


If you want to file for an ITIN number in-person then you can simply visit the nearby IRS office and ask them for a W-7 form. You’re supposed to fill out the form, attach your tax return and documents to prove your identity. Those documents must be certified by the issuing agency. Once done with the form and everything, you can mail them to the IRS.


Another way to apply for an ITIN tax number is to do it online. You can visit a website like and simply follow the steps. Everything is mentioned there, instructions to Form W-7, supporting documentation to ITIN Form W-7 checklist. You can begin by going through the straightforward instructions and gather the documents that are required. Fill out the form and have a final look at the checklist in case you’re missing something.


Last but not the least you can get help from a Certified Acceptance Agent. These agents are authorized by IRS so the point where you previously had to get the documents certified is no more your problem. Your agent will explain you everything and will ask for your original documents and tax return. He/she will then review them and verify them and once done with the verification, your agent will give a green signal to the IRS confirming that yes the documents are valid and the tax return is accurate.
