cooperative must use an EIN for any tax-related purpose even if the entity does not have employees.
However, do not apply for a new EIN if the existing entity only (a) changed its business name, (b) elected on Form 8832 to change the way it is taxed (or is covered by the
default rules), or (c) terminated its partnership status because at least 50% of the total interests in partnership capital and profits were sold or exchanged within a 12-
month period. The EIN of the terminated partnership should continue to be used. See Regulations section 301.6109-1(d)(2)(iii).
Do not use the EIN of the prior business unless you became the “owner” of a corporation by acquiring its stock.
However, grantor trusts that do not file using Optional Method 1 and IRA trusts that are required to file Form 990-T, Exempt Organization Business Income Tax Return,
must have an EIN. For more information on grantor trusts, see the Instructions for Form 1041.
A plan administrator is the person or group of persons specified as the administrator by the instrument under which the plan is operated.
