Receiving a foreign gift, inheritance, or trust distribution may not trigger U.S. tax, but it can create reporting obligations that taxpayers should understand before funds or property change hands.
Cross-border gifts, inheritances, and trust distributions are becoming increasingly common as families, investments, and assets span multiple countries. Yet many U.S. taxpayers are unaware that these transactions may trigger reporting requirements even when no U.S. income tax is due.
From foreign inheritances and gifts to trust distributions and ownership interests in foreign trusts, understanding the rules early can help taxpayers meet their filing obligations, maintain appropriate records, and navigate complex cross-border transactions with greater confidence.
When assets move across borders, determining whether a foreign reporting obligation exists often starts with understanding the nature of the arrangement. For U.S. tax purposes, a trust is considered domestic only if a U.S. court can exercise primary supervision over its administration and one or more U.S. persons control all substantial decisions. If either requirement is not met, the trust is generally treated as a foreign trust.
A trust may be classified as foreign when it is administered outside the United States, is subject to the primary supervision of a foreign court, or when U.S. persons do not control all substantial decisions of the trust. The determination depends on the trust’s governing documents and how it operates in practice. A trust is not necessarily domestic simply because its creator or a beneficiary resides in the United States.
Reporting obligations can also arise when a U.S. person receives money or property from outside the country. A U.S. individual who receives more than $100,000 in gifts or bequests from a nonresident alien individual or foreign estate during the year will generally need to report the amounts on Form 3520. Lower thresholds apply to gifts received from foreign corporations and foreign partnerships. For 2026, that threshold is generally $20,573. Gifts received from related foreign persons may need to be aggregated when determining whether a reporting threshold has been exceeded.
Because the IRS evaluates transactions based on their underlying facts and circumstances, taxpayers should maintain documentation identifying the source of funds, the relationship between the parties, the amount and timing of transfers, the purpose of the transaction, and any supporting bank, legal, or estate records. The description included on a wire transfer alone does not necessarily determine how the transaction will be treated for U.S. reporting purposes.
Once a foreign trust, gift, inheritance, or distribution is involved, taxpayers may need to file one or more information returns with the IRS. The most common is Form 3520, which is used to report certain transactions involving foreign trusts, as well as large gifts and inheritances received from foreign persons.
A U.S. person may need to file Form 3520 if they:
Form 3520 is an information return. Reporting a transaction on the form does not necessarily mean tax is due. However, filing requirements should be reviewed carefully, as missed filings can result in substantial penalties.
A foreign trust with a U.S. owner generally has an annual Form 3520-A filing requirement. A U.S. person may be treated as the owner of a foreign trust even if they are not the trustee and do not directly control the trust. For example, a person who transfers property to a foreign trust that can benefit a U.S. person may be treated as the owner of part or all of the trust.
The U.S. owner is generally responsible for ensuring Form 3520-A is filed, even if a foreign trustee is involved. If the foreign trust does not file Form 3520-A, the U.S. owner generally must file a substitute Form 3520-A with their Form 3520. For calendar-year trusts, the form is generally due March 15, and extensions of an individual income tax return do not automatically extend this deadline.
Foreign trust distributions can also take different forms. In addition to cash payments, the IRS may treat certain loans, the use of trust-owned property, or payments made on behalf of a beneficiary as distributions.
Distributions may also carry additional tax implications when a trust has accumulated income from prior years, making it important to obtain complete information from the trustee before receiving assets.
Foreign trust and gift reporting often involves multiple jurisdictions, varying documentation requirements, and filing deadlines that differ from an individual’s income tax return. Reviewing a transaction before funds or property are transferred can help taxpayers understand their obligations, gather the appropriate records, and address reporting requirements proactively.
Because Forms 3520 and 3520-A carry significant penalties for noncompliance, taxpayers who discover a missed filing should seek guidance before submitting a late return. Reasonable-cause relief may be available in certain circumstances.
