Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter J — Estates, Trusts, Beneficiaries, and Decedents › PART I — ESTATES, TRUSTS, AND BENEFICIARIES › Subpart E — Grantors and Others Treated as Substantial Owners › § 679
If a U.S. person puts property into a foreign trust and any part of that trust helps a U.S. person in the same tax year, the giver is treated as owning the part of the trust that came from their property for tax purposes. This does not apply to gifts made because of the giver’s death or when the giver got at least the property’s fair market value back. Some debts and guarantees by the trust or related people usually don’t count when checking the fair-value rule, but when the trust pays down those debts, the paid amount reduces the part treated as coming from the transfer. If a non-U.S. person who made the transfer becomes a U.S. resident within 5 years, the law treats them as if they transferred the trust portion on their residency start date. The same idea applies if a U.S. person’s domestic trust later becomes a foreign trust while that person is alive. If the trust gets a U.S. beneficiary after the transfer, the transferor may have to report the trust’s undistributed net income from the prior year as taxable income. A trust is counted as having a U.S. beneficiary unless no income or assets could be paid to a U.S. person during the year or if the trust ended. Payments to certain foreign entities can still count as benefiting a U.S. person in specific cases (for example, a controlled foreign corporation, a partnership with a U.S. partner, or another trust with a U.S. beneficiary). Someone who becomes a U.S. person more than 5 years after the transfer is ignored. If anyone can choose who gets trust money, the trust is treated as having a U.S. beneficiary unless the trust clearly limits recipients to a class that has no U.S. persons that year. Any agreement that could lead to U.S. persons getting trust benefits is treated as part of the trust. Loans or free use of trust property to a U.S. person count as benefits unless repaid at market terms within a reasonable time. The IRS can assume the trust has a U.S. beneficiary unless the transferor gives proof and required information, and the IRS will make rules to enforce these ideas.
