| Owner | Treated as owner of any part of a foreign trust under the grantor trust rules | Form 3520-A | Annual return of a foreign trust with a U.S. owner; if the trust has not filed, a substitute Form 3520-A is attached to the owner's timely Form 3520 |
| Recipient | Received a distribution, a loan or use of trust property, or a certain foreign gift | Form 3520 | Part III reports distributions; Part IV covers receipt of certain foreign gifts |

| FBAR and a trust beneficiary | Trust beneficiary with a financial interest in the trust's foreign financial accounts | FinCEN Form 114 | FinCEN's instructions provide an exception for a trust beneficiary with the financial interest described in section (2)(e) of the definition: the trust, trustee or agent is a U.S. person and files an FBAR disclosing the trust's foreign accounts. |
