SS-4 Line 10: A New Business, Banking Purpose, and the Actual EIN Reason
· 6 min read
The practical answer
A bank's request for an EIN may be the event that starts an application, but it does not explain every detail of the applicant's circumstances. A useful preparation file identifies the real application purpose before selecting a reason on the form. Three details shape the review: What event prompted the application? What is the applicant's actual EIN purpose? Does a special reason instruction apply to this entity?[1, p.5] [2, p.1]
Scope and the records behind the answer
The discussion follows the entity, form and transaction conditions identified below. The same label on a different form can have a different purpose. Keep the relevant entity and reporting period visible while you compare the requirements, and treat each stated exception as part of the rule rather than an optional footnote.
Official sources checked: 2026-11-09. Annual tax-year forms and continuously revised forms are identified separately in the references.

Work through the official requirements
Reason required
Select one, and only one, reason for applying on line 10. Do not enter N/A.[1, p.5]
Foreign owned de reason
A foreign-owned U.S. disregarded entity subject to Form 5472 obligations uses the application-reason wording specified in the instructions under Other on line 10.[1, p.5]
Field/section 10: Reason for applying (check only one box)
Select one accurate application reason. A foreign-owned U.S. disregarded entity subject to Form 5472 follows the instructions' Other-reason wording.[2, p.1] [1, p.5]
Designee scope
The third-party designee may answer questions about the completed SS-4 and receive the new EIN. Signed authorization is required, and that authority ends when the EIN is assigned and released to the designee.[1, p.6]
Authorized signer
The authorized SS-4 signer depends on the type of applicant. A foreign applicant may use a person with appropriate authorization to sign.[1, p.6]
Foreign owned de 5472 label
A wholly foreign-owned U.S. disregarded entity applying for an EIN to meet Form 5472 obligations checks Other on line 9a and enters Foreign-owned U.S. disregarded entity-Form 5472 as directed.[1, p.5]
This applies when: The U.S. disregarded entity is wholly owned by a foreign person. The EIN application is for section 6038A/Form 5472 requirements.
No employees line15
For the ordinary employer branch, line 15 asks for the first date wages or annuities were paid, with N/A entered if no employees are planned. An applicant acting as a withholding agent follows the separate instruction for the date payments to nonresident aliens begin.[1, p.6]
This applies when: The ordinary employer and withholding-agent branches are separate; having no employees does not eliminate an applicable withholding-agent date requirement.
Not entity election
Checking an entity-type box on SS-4 is not itself an entity-classification tax election.[1, p.4]
Previous ein disclosure
Line 18 asks whether the applicant previously received an EIN. If Yes, enter that prior EIN.[2, p.1]
An illustrative preparation scenario
In this hypothetical preparation example, a newly organized business brings a bank email and asks the preparer to tick the banking option immediately. The formation and planned reporting records suggest that another explanation may also need review. The draft remains open until the actual purpose is reconciled with the specific instructions. The preparer checks three points: What event prompted the application? What is the applicant's actual EIN purpose? Does a special reason instruction apply to this entity? The file remains a working comparison until the relevant facts and applicable instructions have been checked together. No agency outcome is assumed.[1, p.5] [2, p.1]
This is a planning illustration, not a statement that a particular filing has been accepted or that an entity qualifies for a tax result. Use the source-backed distinctions above to decide what information still needs to be established before a form is completed.
A review sequence you can actually use
- What event prompted the application?
- What is the applicant's actual EIN purpose?
- Does a special reason instruction apply to this entity?
Write down the answer and the record that supports it, rather than marking a question complete because a field contains text. When two records disagree, identify whether the difference concerns the entity, an individual, the reporting period or the type of change. That makes the remaining question specific enough to resolve against the relevant instruction.
Keep the scope of a preparation service separate from the government requirement. A service intake question may gather information for a workflow; it does not create an exception, extend a deadline or determine whether a transaction is reportable. The cited government material remains the basis for those conclusions.
Questions to settle before moving forward
How should I check field/section 10: reason for applying (check only one box)?
Select one accurate application reason. A foreign-owned U.S. disregarded entity subject to Form 5472 follows the instructions' Other-reason wording. [2, p.1] [1, p.5]
How should I check designee scope?
The third-party designee may answer questions about the completed SS-4 and receive the new EIN. Signed authorization is required, and that authority ends when the EIN is assigned and released to the designee. [1, p.6]
How should I check authorized signer?
The authorized SS-4 signer depends on the type of applicant. A foreign applicant may use a person with appropriate authorization to sign. [1, p.6]
How should I check foreign owned de 5472 label?
A wholly foreign-owned U.S. disregarded entity applying for an EIN to meet Form 5472 obligations checks Other on line 9a and enters Foreign-owned U.S. disregarded entity-Form 5472 as directed. The U.S. disregarded entity is wholly owned by a foreign person. The EIN application is for section 6038A/Form 5472 requirements.[1, p.5]
