Grantor trust rules in sections 671 to 679
Grantor trust rules cover definitions, ownership tests, foreign trust beneficiaries, and statutory links to U.S. reporting rules.
Definitions come first
Section 672 defines an adverse party by a substantial beneficial interest that the exercise or nonexercise of a trust power would adversely affect. A nonadverse party is anyone outside that definition.[1]
A related or subordinate party is a nonadverse party within specified family, employment, or corporate relationships. The listed family relationships include a spouse living with the grantor, parents, descendants, and siblings.[1]
For section 672(f) and sections 674 and 675, a related or subordinate party is presumed subservient to the grantor unless a preponderance of evidence establishes otherwise. Section 672 also attributes specified spousal powers and interests to the grantor, including powers created before marriage for periods after the marriage begins.[1]
How the ownership tests fit together
The ownership tests address specified portions of a trust. Section 674 addresses control over beneficial enjoyment, section 675 addresses administrative powers, and section 676 addresses powers that can return title to the grantor.[2][3][4]
Section 677 addresses income available for the grantor or spouse, while section 678 can assign ownership to someone other than the grantor. Section 679 addresses property transferred by a United States person to a foreign trust with a United States beneficiary.[5][6][7]
Control over beneficial enjoyment
Section 674 generally assigns ownership where the grantor or a nonadverse party can determine beneficial enjoyment of trust property or income without an adverse party's approval. Its exceptions depend on the particular power and its limits.[2]
One exception covers distributions of trust principal to beneficiaries under a reasonably definite standard written into the trust instrument. Another covers allocating receipts and disbursements between principal and income, including broadly expressed allocation powers.[2]
Section 674(c) provides an exception for specified distribution powers held solely by trustees, none of whom is the grantor and no more than half of whom are related or subordinate parties subservient to the grantor. A power to add beneficiaries generally prevents that exception, with an exception for children born or adopted afterward.[2]
Administrative powers and borrowing
Section 675 assigns ownership under specified transaction, borrowing, and administrative conditions. One trigger is a power permitting dealings with trust property for inadequate monetary value, exercisable by the grantor or a nonadverse party without an adverse party's approval.[3]
A borrowing power without adequate interest or security also falls within section 675, subject to an exception for a trustee other than the grantor exercising a general lending power. Actual borrowing that remains unpaid, including interest, at the start of the taxable year is a separate trigger, with an exception for adequately secured, adequately interest-bearing loans from specified trustees.[3]
Specified administrative powers trigger ownership when exercisable in a nonfiduciary capacity without approval from anyone acting in a fiduciary capacity. These include reacquiring trust principal through substitution of property of equivalent value.[3]
Revocation and income for the grantor
Section 676 assigns ownership when the grantor, a nonadverse party, or both can return title to a trust portion to the grantor. A conditional exception addresses powers affecting income enjoyment only after an event linked to section 673's reversionary-interest test.[4]
Section 677 covers income that can reach the grantor or spouse without an adverse party's approval, including amounts retained for later distribution. It also covers certain life insurance premiums, except policies irrevocably payable for a purpose specified in section 170(c).[5]
A discretionary power to support a beneficiary other than the spouse does not alone make the income taxable to the grantor under section 677(b). Where the grantor has a legal support obligation, the exception extends only to income that has not actually been used for that support.[5]
Ownership by someone other than the grantor
Section 678 can treat another person as owner when that person alone can vest trust principal or income in themselves. It also addresses partial releases or modifications where sufficient control remains under the principles of sections 671 to 677.[6]
The rule does not apply to an income power where the grantor or a section 679 transferor is otherwise treated as owner under another provision of the subpart. A power renounced or disclaimed within a reasonable time after its holder learns of it also falls outside section 678(a).[6]
Foreign trusts and United States beneficiaries
Section 679 generally assigns ownership to a United States transferor where a foreign trust has a United States beneficiary during the taxable year, excluding trusts described in section 6048(a)(3)(B)(ii). Ownership attaches to the portion attributable to the transferred property.[7]
Exceptions cover transfers resulting from death and exchanges for at least fair market value. Special rules restrict which obligations count toward the exchange value.[7]
A foreign trust is treated as having a United States beneficiary if income or principal may benefit a United States person during the taxable year, including upon termination during that year; an interest dependent on a future event can still count.[7]
The statutory connection to reporting
Section 679 expressly connects certain deemed transfers with section 6048. If a citizen or resident transferred property to a domestic trust that becomes foreign during that person's lifetime, both sections apply as though the attributable portion were transferred when the trust became foreign.[7]
Section 679(d) also links beneficiary treatment to information submitted to the Secretary. Its presumption can apply unless the transferor supplies required transfer information and demonstrates that both statutory conditions excluding United States beneficiaries are satisfied.[7]

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. | |

Questions and answers
Does ownership treatment always cover the whole trust?
The statutes frame ownership by reference to a trust portion. Section 679 ties that portion to the property transferred.[2][7]
Can a spouse's power count as the grantor's power?
Section 672 attributes specified spousal powers and interests to the grantor. For someone who marries the grantor after the power is created, attribution applies to periods after the marriage begins.[1]
Does a notice requirement remove a trust power?
Section 672 treats a person as holding a covered power despite a prior notice requirement. The same rule applies when exercise takes effect after a specified waiting period.[1]
Can using foreign trust property count as a benefit?
Section 679 includes loans of cash or marketable securities and use of other trust property in its beneficiary rule. An exception applies to timely repayment with market interest or payment of fair market value for use.[7]
