Applying for ITIN Tax Number? Form W-7 Instructions

An ITIN tax number, or Individual Taxpayer Identification Number, is a nine digit number used solely for the tax administration purpose in the United States. In order to apply for an ITIN tax number, an individual must provide original proof of identification and fill out the W-7 form.

Purpose of the W-7 Form

W-7 form is an ITIN tax number form that each individual has to submit to the IRS (Internal Revenue Service). The main purpose of the W-7 from is that it draws a line between the ITIN tax number and SSN. Individuals who are not eligible for a Social Security Number are the ones who are issued with an ITIN.

ITIN tax number is used for Federal Tax purposes only and it does not change an individual’s immigration status nor does it entitle you to SSN benefits. Individuals who are filing their tax returns via ITIN tax number are also not qualified for EIC (Earned Income Credit). ITINs now have an expiration period of 5 years and if a taxpayer needs an ITIN tax number even after the expiration period then he/she must reapply.

If an individual has a SSN then there’s no point applying for the ITIN tax number. Any individual who is U.S citizen or admitted by U.S for permanent residence or U.S employed is eligible for a SSN. To apply for a SSN, SS-5 form should be filled and this form is available at the Social Security Administration office. If SSN application process is pending then an individual should not apply for the ITIN tax number.

Who Must Apply for the ITIN Tax Number?

Any individual who is not qualified for a SSN and has certain tax implications must always file for an ITIN tax number. Individuals such as:

  • A nonresident alien individual claiming reduced withholding under an applicable income tax treaty for which an ITIN tax number is required.
