If a third party designee is completing the online application on behalf of the taxpayer, the taxpayer must authorize the third party to apply for and receive the EIN on his or her behalf, according to the process below:
- The taxpayer must sign a completed Form SS-4 (Application for Employer Identification Number), including the third party designee section, prior to the third party making the online application. A copy of the signed Form SS-4 must be retained in the third party's files.
- The taxpayer must read and sign a statement that he/she understands that he/she is authorizing the third party to apply for and receive the EIN on his or her behalf, and to answer questions about completion of the form. A copy of the signed statement must be retained in the third party's files.
- The assigned EIN will be disclosed to the third party upon successful completion of the online application.
- The taxpayer will receive a computer-generated notice from the IRS stating that the EIN was assigned.
