Foreign trust
The Form 3520 instructions describe a foreign trust through its connections to transfers and ownership, as well as distributions. For U.S. federal tax purposes, a trust is domestic only if it satisfies both the court test and the control test; otherwise it is foreign.
Meaning under the IRS rules
The IRS instructions for Form 3520 use foreign trust for a trust classified as foreign under the court and control tests. A trust is domestic only when it meets both tests. Failure of either test makes it foreign for federal tax purposes.[3]
The court test asks whether a court in the United States can exercise primary supervision over the trust's administration. The control test asks whether one or more U.S. persons control all substantial decisions of the trust. A reader can therefore encounter this term as a classification, independent of how a trust is described in its governing documents.[3]
Where the term appears
The term appears throughout Form 3520 instructions, which cover transfers by a U.S. person to a foreign trust. They also address ownership of trust assets and receipt of distributions. The instructions describe exceptions from reporting for specified transfers and transactions, including certain tax-favored foreign trusts when stated conditions are met.[1]
Section 6048 groups reporting into reportable events and U.S. ownership. It also covers distributions to U.S. beneficiaries. Reportable events include creation of a foreign trust by a U.S. person and transfers of money or property by a U.S. person to a foreign trust. Form 3520 is the form named in the instructions for these reporting categories.[1][6]
The instructions for Form 3520-A address the annual information return for a foreign trust with a U.S. owner. If the foreign trust does not file Form 3520-A, the instructions require the U.S. owner to attach a substitute Form 3520-A to the owner's Form 3520 filed by its due date, including extensions.[2]
Related terms and rules
Foreign trust is related to domestic trust because the regulations use the two categories to classify trusts. Grantor trust and nongrantor trust describe ownership treatment under separate rules. The IRS explains that a U.S. person treated as the owner under sections 671 through 679 has reporting responsibilities tied to the trust.[1]

Reg. s. 301.7701-7(d)(1)(iii) | Control | "the power, by vote or otherwise, to make all of the substantial decisions of the trust, with no other person having the power to veto any of the substantial decisions." The test considers all persons who have authority to make a substantial decision, not only the trust fiduciaries. | Treas. Reg. s. 301.7701-7(d)(1)(iii) |
| Step 2 · Treated as owned or not (a trust or any portion of a trust) | Grantor trust rules | Sections 671 through 679 (subpart E). The Form 3520 instructions count as a grantor any person treated as the owner of any part of a foreign trust's assets under these sections. | |

Exceptions include transfers by reason of death and transfers for at least fair market value. | |
| Step 2 · Treated as owned or not (a trust or any portion of a trust) | Section 672(f)(1) | The grantor trust rules apply only to the extent they result in an amount being "currently taken into account" in computing the income of a U.S. citizen or resident or a domestic corporation. | |

Foreign trust (statutory usage)
The statutory meaning of foreign trust depends on the law using the term. The Trusts (Jersey) Law defines a foreign trust as a trust whose proper law is another jurisdiction's law. It defines a Jersey trust as one whose proper law is Jersey law, so the labels turn on governing law.[8]
Bermuda's Trusts (Special Provisions) Act defines the term by contrast with its local category. A trust governed wholly or partly by Bermuda law is a Bermuda trust, and any other trust is a foreign trust.[9] These definitions concern governing law, while U.S. federal tax classification depends on the court and control tests.[8][9]
The Jersey definition appears in the interpretation article of the Trusts (Jersey) Law. Part 3 applies only to a foreign trust, while Part 4 applies to a Jersey trust and, where context permits, to a foreign trust. Under Jersey law, a foreign trust's proper law governs its interpretation, subject to stated exceptions. Certain provisions are also excluded for a foreign trust whose proper law is that of a jurisdiction covered by the Convention.[8]
Bermuda's Act uses the label in provisions for foreign trusts meeting a local connection rule. The conditions are a trust instrument conferring jurisdiction on Bermuda courts and trust administration carried on in Bermuda.[9]
The Hague Trusts Convention defines trust, rather than foreign trust, as a legal relationship created during life or on death. Assets are placed under a trustee's control for a beneficiary or specified purpose, form a separate fund, and are held in title by or for the trustee. The trustee manages, uses, or disposes of the assets under the trust terms and legal duties. Reserved settlor powers and a trustee's own beneficiary rights are not necessarily inconsistent with a trust. The Convention applies only to trusts created voluntarily and evidenced in writing; it specifies applicable law and governs recognition.[10]
Questions and answers
How does the IRS distinguish a foreign trust from a domestic trust?
The regulations apply a court test and a control test. A trust is domestic only if it meets both, so failing either test means it is foreign for federal tax purposes.[3]
What U.S. forms are associated with a foreign trust?
The Form 3520 instructions identify reporting for transfers and ownership. They also address distributions. Form 3520-A is the annual information return for a foreign trust with a U.S. owner.[1][2]
Does every transfer to a foreign trust count as a reportable event?
Section 6048 defines reportable events to include creation of a foreign trust by a U.S. person and transfers of money or property by a U.S. person to a foreign trust. The Form 3520 instructions also describe specified exceptions from reporting.[1][6]
How does a foreign trust relate to U.S. ownership?
A U.S. person treated as owner of any portion under the grantor trust rules has information reporting responsibilities. Section 679 addresses certain transfers by U.S. persons to foreign trusts with U.S. beneficiaries.[5][6]
What is the difference between grantor and nongrantor trust?
A grantor trust is a trust, or portion of a trust, treated as owned by a person under sections 671 through 679, while a nongrantor trust is a trust, or portion, not treated as owned by another person under those rules. The foreign trust classification is determined under the court and control tests. Ownership treatment is addressed under the grantor trust rules.[1][3]
