Due diligence and controlling persons of a trust

OECD and U.S. reporting frameworks describe due diligence, controlling persons and beneficial ownership for trusts with financial accounts.

What due diligence means

Under the Common Reporting Standard, due diligence is the set of procedures financial institutions use to determine which accounts are reportable and what information must be reported. The Standard sets rules for covered institutions, accounts and information, and identifies account review as part of the process.[10]

The CRS definition covers an account held by a Reportable Person, or an account held by a Passive Non-Financial Entity that has a Controlling Person who is a Reportable Person.

A separate U.S. framework appears in the U.S.-Switzerland FATCA agreement. It defines Controlling Persons for a trust and provides for identification of U.S. Reportable Accounts, with information reported annually to the Swiss Competent Authority under the agreement.[7]

Who the frameworks call controlling persons

For FATCA purposes under the U.S.-Switzerland agreement, a trust's Controlling Persons include its settlor, trustees, any protector, beneficiaries or beneficiary class, and other natural persons exercising ultimate effective control.

Reporting scope can depend on account classification and the available information. For a trust that is a Passive NFE, the Handbook says reportable Controlling Persons are reported, and the person's role is expected when available. The Handbook also describes an option under which discretionary beneficiaries are reported in years when they receive trust distributions.[10]

The Jersey Trusts Law describes a trust as property held by a trustee who is not its owner in their own right, for a beneficiary or a purpose beyond the trustee's own benefit. The law also requires trustees to keep accurate records and to keep trust property separate from personal property and identifiable apart from other trust property.[1]

How beneficial ownership is described

Belize's Financial Services Commission guidance gives a trust example in which natural-person parties are identified as beneficial owners unless they act as nominees for someone else. In the Torres Trust example, the settlor and named beneficiaries are identified; an entity beneficiary or trustee is not itself treated as the natural-person beneficial owner, so individuals behind a trust in the chain are identified.[2]

The CRS and FATCA terms are reporting definitions used in their respective frameworks.

Trust account review and due diligence

Account review

OCC guidance expects banks to establish a due diligence process for each prospective account, consider applicable risk management issues, check compliance with bank policies and procedures, and document the review results in the appropriate file.[13]

Identity documents and contributors

The Isle of Man Financial Services Authority expects customer due diligence on the person contributing the trust's corpus where a nominee settlor has been used.[15]

Practitioner commentary says establishing a trust structure in the BVI or Cayman requires verified KYC documentation and information relating to individuals and corporate entities.[16]

Beneficial owners and controlling persons

South Dakota guidance defines a trust customer's beneficial owners to include trustees and other people who, under the governing document, effectively control the trust or its property, can amend the trust, or can appoint or remove trustees.[17]

For CRS purposes, the OECD handbook identifies settlors, trustees, beneficiaries, protectors, and other natural persons exercising ultimate effective control over the trust as Controlling Persons.[10]

Assets and their source

A trust company's review includes identifying the assets an underlying legal entity owns and their source, along with ongoing trustee review of asset holdings.[18]

Account classification

Practitioner commentary says a private trust vehicle classified as a non-financial entity under CRS may still need to provide its financial institution with a status self-certification, controlling-person details, and related due diligence materials.[19]

Questions and answers

Who counts as a controlling person of a trust under FATCA?

The U.S.-Switzerland agreement includes the settlor, trustees, any protector, beneficiaries or beneficiary class, and other natural persons exercising ultimate effective control.

How does the CRS decide whether a trust account is reportable?

The CRS definition includes accounts held by Reportable Persons and accounts held by a Passive NFE with a Controlling Person who is a Reportable Person. The CRS sets two tests for establishing this status.[10]

Are all trust beneficiaries reported under the CRS?

The Handbook describes an option that can limit reporting of discretionary beneficiaries to years in which they receive distributions. It also says that mandatory beneficiaries are included in the reporting framework's account information table.[10]

What does Jersey law say a trust is?

Jersey law describes a trust as property held by a trustee who is not its owner in their own right. The property is held for a beneficiary or for a purpose that is not solely for the trustee's benefit.[1]
