With tax season now here, we wanted to share a little-known (but important) requirement from the IRS that will directly affect millions of immigrants when filing their taxes this year.

As you may know, for immigrants who do not have a Social Security number, the IRS requires that an Individual Taxpayer Identification Number (ITIN) be entered on tax returns instead.  For immigrants who do not already have their ITIN, the IRS now requires those applying for one to submit either original documents or certified copies of original documents prepared by the issuing agency (i.e. passports and other forms of primary identification) with their Form W-7.
