We believe that you would have to obtain a tax ID number for a land trust, as you would for any other type of trust. The Customer Identification Program (CIP) rules require that you obtain a tax ID number from all customers, including trusts. 31 CFR 1020.220(a)(2)(i). A “customer” includes any person opening a new account (31 CFR 1020.100(c)(1)(i)), and the term “person” includes individuals and legal entities (31 CFR 1010.100(mm)). Also, the term “account” includes “a relationship established to provide . . . trust services.” 31 CFR 1020.100(a)(1). See also the FFIEC’s BSA/AML Examination Manual, which states that the CIP rules require financial institutions to verify the identity of a trust. Trust and Asset Management Services—Overview.  

Whether you need to obtain a separate EIN for a trust, rather than using the grantor’s social security number, depends on how the trust’s tax return is filed. The instructions for the estate tax return, Form 1041, state that every trust that is required to file Form 1041 must have an EIN. Form 1041 Instructions, Employer Identification Number. However, some trusts are not required to file Form 1041 returns. For example, if a trust is considered a “grantor trust,” it is not required to file a Form 1041, and we would assume that the grantor’s social security number would suffice for that type of trust.
