If one attempts to input an entity's name and EIN in the online EIN application now, the website immediately displays an error message because it can't validate the EIN against its individual taxpayer database. I've entered my own SSN to double check - it will validate me and my SSN, so it's definitely looking at the individual taxpayer database.
The thing is, I have hard copies of screen prints of SS-4 applications processed via the online EIN application for clients over the years, and the website definitely used to permit the entry of an entity name and EIN.
The caption for Line 7b on the current Form SS-4 is "SSN, ITIN or EIN" - which implies that an EIN is a permissible entry for Line 7b.
The current instructions state "Lines 7a-b: Name of responsible party. Enter the full name (first name, middle initial, last name (if applicable) and SSN, ITIN, or EIN of the entity's responsible party."
Note the parenthetical "(if applicable)" with respect to entering the first name, middle initial, and last name. Note as well the explicit reference to an EIN.
The instructions go on to state: "Responsible party defined. The “responsible party” is the person who ultimately owns or controls the entity or who exercises ultimate effective control over the entity. The person identified as the responsible party should have a level of control over, or entitlement to, the funds or assets in the entity that, as a practical matter, enables the person, directly or indirectly, to control, manage, or direct the entity and the disposition of its funds and assets. Unless the applicant is a government entity, the responsible party must be an individual (i.e., a natural person), not an entity."
That last bolded sentence in the definition makes no sense when the entity applying for the EIN is an employer plan. By definition, it's the employer - as plan sponsor - who acts to establish an employer-sponsored retirement plan, and not an employee or officer of the plan sponsor. Moreover, looking at the rest of the definition, the employer clearly is the "person" who "controls" the plan and who "exercises effective control over" the plan. Therefore it is the plan sponsor who is the "responsible party" - and the appropriate "person" - albeit a legal person, rather than a natural person - to be listed as the "responsible party."
Consider the implications with respect to applying for an EIN for a plan committee that is designated by the terms of an employer plan as the plan administrator. Other message threads on this site discuss the Form 5500's requirement that a plan administrator that is not the plan sponsor must have its own EIN and report it on Form 5500. Many plans designate a committee as the plan administrator, and, as a result, many plan committees have obtained EINs over the past several years for Form 5500 reporting purposes. It's the plan that designates the committee as plan administrator, and the plan generally will reference the board of directors of the employer as the entity that selects of designates the members of the plan committee. So who is the "responsible party" here for purposes of completing a Form SS-4 to obtain an EIN for the plan committee? The IRS will tell you it is the employer! I know this because an IRS representative told me this when I assisted a plan committee with obtaining an EIN several years ago, and I have a screen print of the online data entry - completed online while talking to that same IRS representative on the phone - showing the name of the employer and its EIN as the information entered for Lines 7a and 7b.
So... in a plan committee scenario, given the definition of "responsible party" in the instructions and the online EIN application's restriction on entering an EIN, whose SSN should be entered as the "responsible party" for the plan committee? Hmmm....
