Entity data
The legal name, addresses and Articles data are aligned before SS-4 is prepared.
An EIN is a federal taxpayer identifier issued by the IRS. The number itself is free, while correct data, signature and filing-route preparation require an organised workflow.
Responsible-party data, SS-4, signature and the correct IRS route are organised as one process.

In many cases a foreign responsible party without an SSN/ITIN does not use the online assistant and instead follows the Form SS-4 route accepted by the IRS. The identification entry, signature and submission channel depend on current instructions and the facts.
The legal name, addresses and Articles data are aligned before SS-4 is prepared.
The correct person, identification status and IRS data set are identified.
The form and signature instructions are prepared for an available submission route.
The route, status, corrections and secure delivery of the confirmation are coordinated.
| Stage | Go Solutions coordination | Client input |
|---|---|---|
| Source data | Consistency review of the name, addresses, Articles and application reason. | Current and accurate data plus approval of the selected route. |
| Responsible party | Data arranged under the current SS-4 instructions. | Confirmation of the authorised person and authority to act. |
| Signature | Form and signature instructions; third-party designee only with proper authorisation. | Signature by an authorised person and timely return. |
| Status | Follow-up and coordination of questions or corrections. | Prompt answers if the IRS requests more information. |
Form SS-4 is signed by an authorised person. A third-party designee requires proper authorisation. Go Solutions does not submit without clear authority and compliance with the current IRS process.
