irs-taxid-numbers.com acts as an Authorized E-File Provider as described in the instructions to Form SS-4 to help clients obtain Federal Tax ID Numbers from the IRS. We are a business-to-business (B2B) application assistance and filing service and are not affiliated with the IRS or any other federal or state organizations. We do not provide legal, financial or other professional advice. We are not a law or an accountancy firm nor are we affiliated with either. Users are able to obtain a Tax ID number on their own by working directly with the IRS, but they will not be able to use the streamlined application process or engage with e-mail support.
