26 U.S.C. § 672, Definitions and rules
26 U.S.C. § 672 defines terms and rules used in a subpart of the Internal Revenue Code concerning trusts. For a U.S. citizen, it explains how certain interests and powers are treated under that subpart, including in specified foreign trust situations.
Document and scope
Section 672 is a provision of Title 26, the Internal Revenue Code, published online by the Office of the Law Revision Counsel of the United States House of Representatives. It appears in Chapter 1 and sets definitions and rules for the subpart in which it is located. Its text covers adverse and nonadverse parties, related or subordinate parties, powers subject to prior notice or delay, spouse-held interests, and limits and special rules for applying the subpart.[1]
The provision supplies interpretive rules for that subpart. It does not itself set out a complete set of U.S. information return instructions for foreign trusts or foreign accounts, so its subject is trust ownership and attribution rules within the Code.[1]
Key definitions and attribution rules
An adverse party is defined by a substantial beneficial interest that would be affected adversely by exercising or not exercising a power over the trust. A holder of a general power of appointment over trust property is treated as having a beneficial interest. A nonadverse party is simply a person who does not meet the adverse-party definition.[1]
A related or subordinate party must be nonadverse and fall within specified relationships or roles. These include a spouse living with the grantor, certain close family members, and certain employees or corporate employees described in the statute. For the purposes of subsection (f) and sections 674 and 675, the statute presumes such a party is subservient to the grantor unless evidence establishes otherwise under the stated standard.[1]
A power can count under the subpart even if notice must come first or its effect begins only after a specified waiting period. The grantor is also treated as holding certain powers or interests held by a person who was the grantor's spouse when the power or interest arose. For a person who marries the grantor later, this treatment applies only to periods after the marriage; legal separation under the specified decree means the person is not considered married for the relevant rule.[1]
Foreign trust connection and U.S. reporting context
Section 672(f) generally limits the subpart's application to amounts taken into account in computing income under the Code for a U.S. citizen or resident, or a domestic corporation. The statute then states exceptions and special rules, including rules for certain revocable or irrevocable trust portions and compensation trusts. These provisions address how ownership and income treatment may operate in defined circumstances involving foreign persons and trusts.[1]
One special rule applies where a foreign person would otherwise be treated as owner of a trust portion and the trust has a U.S. person beneficiary. If that beneficiary transferred property to the foreign person, the beneficiary is treated as grantor of that portion to the extent of those transfers, subject to the statutory terms and exception for certain gifts. This can matter to a U.S. citizen connected to a foreign trust because it defines whose role as grantor is recognized under this subpart.[1]

|---|---|---|---|
| During the settlor's lifetime | Foreign grantor trust (FGT) | A trust or portion treated as owned under the grantor trust rules, sections 671 through 679. | Section 672(f)(1) applies those rules only to the extent an amount is currently taken into account, directly or through entities, in computing the income of a U.S. citizen or resident or a domestic corporation. |
| Event | Death of the settlor | Grantor trust status generally ends at the settlor's death. | |
| After the settlor's death | Foreign non-grantor trust (FNGT) | A foreign grantor trust generally converts automatically to foreign non-grantor trust status after the settlor's death. | |
| What the throwback regime reaches | Income accumulated after grantor-trust status ends, reached through distributions to U.S. beneficiaries in later years. | ||
| Notes | Treatment depends on the facts and on the rules for the tax year concerned. | ||

Income and gains distributed in the year realized: U.S. beneficiaries are generally taxable on income accrued after the grantor's death and distributed to them.
Realized but distributed in a later year: Very generally, income accumulated after grantor-trust status ends and distributed to U.S. beneficiaries in later years falls under the "throwback" rules as "undistributed net income" (UNI).
PFICs and CFCs: Trust assets classified as PFICs or CFCs raise additional considerations.
