An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service. The IRS issues ITINs to individuals who are required to have a U.S. taxpayer identification number but who do not have an eligibility to obtain ASSURE TAX FILER. ITIN is used to claim a benefit while filing the Federal Tax Return if one does not have ASSURE TAX FILER. We will help you getting an ITIN for your dependents & kids in very smooth and efficient way.
