The completed application form is a tax return that you must send to the IRS. The application is filed and sent along with documentation required by the IRS. There are other legal and business requirements that must be met. We help you meet those requirements. You just send the form to us!

These documents can include a copy of the tax return, an official IRS letter, the original tax return, an official IRS letter from the original provider of the information, a government-issued identification number, a social security number, a Medicare number, a veteran's ID number, or a copy of a student ID.
