EIN responsible party: who to name

Every EIN application asks for a responsible party, and the IRS means a specific, real person. Naming the wrong one, such as a formation agent, causes problems later. This guide explains who qualifies, who to name in common structures, and what to do when it changes.

Short answer

The EIN responsible party is the individual who ultimately owns or controls the entity, or exercises effective control over it. It must generally be a person, not a company or a nominee. For a single-member LLC it is usually the owner; for a corporation, a principal officer. A foreign responsible party without an SSN or ITIN writes "foreign" or "N/A" on line 7b.

Key facts at a glance, as set out in this guide.

What does the IRS mean by responsible party?

For an entity whose shares are not publicly traded, the responsible party is the individual who has a level of control over, or entitlement to, the funds or assets of the entity that, as a practical matter, enables them to control, manage or direct it and the disposition of its funds and assets. Put simply: the real person in charge. The IRS added this requirement so that it always knows who stands behind an EIN.

Who should you name?

EntityUsual responsible party
Sole proprietorshipThe owner
Single-member LLCThe owner, or the individual who controls the owner if the owner is an entity
Multi-member LLCThe managing member or the individual with effective control
CorporationA principal officer, such as the president or CEO
PartnershipA general partner who controls it
TrustThe grantor, owner or trustor

Only government entities and certain other specified cases can name an entity rather than an individual.

Who should you not name?

  • A formation service, registered agent or nominee who has no real control.
  • An accountant or lawyer, unless they actually control the entity.
  • Another company, where an individual can be identified.

What if the responsible party is foreign?

A foreign individual can be the responsible party. If they have no SSN or ITIN, the December 2025 Form SS-4 instructions say to write "foreign" or "N/A" on line 7b. The application cannot be made online in that case: it goes by fax, mail or the IRS international phone line. See EIN without an SSN or ITIN and Form SS-4 line by line.

How do you get it right?

  1. Identify who really controls the entity

    Owner, managing member or principal officer.

  2. Enter their name and identifying number

    On lines 7a and 7b of Form SS-4.

  3. Keep it current

    File Form 8822-B within 60 days of any change.
