IRS Form 3520-A Explained: Foreign Trust Reporting Requirements for U.S. Owners
This article focuses on Form 3520-A, which is different from Form 3520: Form 3520-A is the annual information return for a foreign trust with a U.S. owner, while Form 3520 covers several foreign-trust transactions and certain gifts from foreign persons. For a calendar-year foreign trust, the regular Form 3520-A deadline is generally March 15, with an extension available by properly filing Form 7004 using the foreign trust’s EIN.

What Is IRS Form 3520-A?
Do you own assets held in a foreign trust? Are you a U.S. taxpayer who transferred money or property to a trust established outside the United States? If so, you may have important federal tax reporting responsibilities.
IRS Form 3520-A, Annual Information Return of Foreign Trust With a U.S. Owner, is used to report information about certain foreign trusts that have at least one U.S. person treated as an owner under the federal grantor trust rules.
The form provides information about the trust, its U.S. owners, and certain U.S. beneficiaries. It also helps determine what trust income a U.S. owner may need to report on an individual or other applicable federal tax return.
At AIM Financial, we help taxpayers understand tax preparation requirements and identify situations where additional international reporting may be necessary. Foreign trust reporting is an area where overlooking a form or deadline can lead to substantial penalties.
What Is a Foreign Trust?
A foreign trust is generally a trust that does not meet the IRS requirements for classification as a domestic trust.
For federal tax purposes, a trust is generally 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 the trust does not meet both requirements, it is generally classified as foreign.
A foreign trust may be established for estate planning, family wealth management, investment holdings, inheritance arrangements, or other purposes.
However, a trust’s legal name or the country where it was created does not, by itself, determine its U.S. tax treatment. The governing documents, administration, and decision-making arrangements must be reviewed.
Who Must File Form 3520-A?
The foreign trust itself generally has the responsibility to file Form 3520-A when it has at least one U.S. owner under the grantor trust rules.
A U.S. owner is a person treated as owning some or all of the trust’s assets for federal tax purposes. These rules can apply to individuals and certain other U.S. persons, depending on the circumstances.
You should investigate the reporting requirements if you:
- Transferred cash or property to a foreign trust.
- Are treated as the owner of a foreign trust under the grantor trust rules.
- Receive information about trust income attributable to you.
- Have an ownership interest in a foreign trust through arrangements that require international tax reporting.
The rules can be complex. A person may be treated as an owner even when the trust is legally separate and the person does not directly hold the assets in their own name.
If a foreign trust has multiple U.S. owners, each owner must ensure the applicable reporting requirements are satisfied for the portion treated as owned by that person.
What Information Does Form 3520-A Report?
Form 3520-A collects information about the foreign trust’s activities, assets, ownership, and beneficiaries. Depending on the circumstances, the form and its statements may include:
- The trust’s name, address, and employer identification number (EIN).
- Information about the trustee and any designated U.S. agent.
- The trust’s assets and liabilities.
- Trust income and distributions.
- Information identifying U.S. owners.
- Information about U.S. beneficiaries who receive distributions.
- Statements showing income attributable to each U.S. owner.
The foreign trust must also provide the appropriate owner and beneficiary statements to the relevant U.S. persons.
These statements matter because the U.S. owner may need to report trust income on their own federal income tax return. The owner should not assume that income is irrelevant merely because the trust retained the money rather than distributing it.
The information must be reported in English, and amounts must be shown in U.S. currency under the IRS instructions.
What If the Foreign Trust Does Not File?
A foreign trustee may not be familiar with U.S. tax rules or may be unwilling or unable to complete the required filing. Unfortunately, that does not necessarily remove the U.S. owner’s responsibility.
If the foreign trust fails to file Form 3520-A, the U.S. owner generally must complete and attach a substitute Form 3520-A to the owner’s Form 3520 by the applicable Form 3520 deadline to help satisfy the reporting requirements.
The owner must also address the required owner and beneficiary statements. This is an important distinction: Form 3520-A is the trust’s annual information return, while Form 3520 is the separate return used by U.S. persons for specified foreign trust transactions, ownership reporting, and certain foreign gifts or bequests.
The two forms may be connected, but they are not interchangeable.
When Is Form 3520-A Due?
Form 3520-A is generally due by the 15th day of the third month after the end of the foreign trust’s tax year.
For a trust using a calendar tax year, the regular deadline is generally March 15 of the following year. If March 15 falls on a weekend or legal holiday, the deadline may shift under the applicable rules.
An automatic six-month extension may generally be requested by filing Form 7004 by the original due date and using the foreign trust’s EIN. An extension for the U.S. owner’s individual income tax return does not automatically extend the foreign trust’s Form 3520-A deadline.
If a substitute Form 3520-A is filed with the U.S. owner’s Form 3520, a different deadline applies: it is due with Form 3520.
Because these deadlines can differ, taxpayers should identify which filing arrangement applies rather than relying on their ordinary individual tax return deadline.
What Are the Penalties for Not Filing?
The penalties for failing to meet foreign trust reporting requirements can be substantial.
Under the IRS instructions, the U.S. owner may face an initial penalty equal to the greater of $10,000 or 5% of the gross value of the portion of the trust’s assets treated as owned by that person at the end of the applicable tax year if the trust fails to file Form 3520-A on time or fails to provide the required information.
Additional penalties may apply in certain circumstances. The specific consequences depend on the facts, applicable exceptions, and the reporting failure involved.
If you discover that a required foreign trust return was missed, consider getting professional tax guidance promptly. The appropriate response may involve reviewing prior-year filings, obtaining trust records, and determining whether a substitute filing or other corrective action is necessary.
How AIM Financial Can Help With Foreign Trust Reporting
Foreign trust reporting can involve complicated ownership rules, overseas records, multiple deadlines, and tax consequences that are not obvious from the trust’s distributions alone.
AIM Financial can help you review your tax documents, identify questions about foreign trust reporting, and prepare your applicable tax returns based on the information available. If you are treated as an owner of a foreign trust, it is important to discuss the arrangement during tax preparation.
For individuals and families in Grand Rapids, Kentwood, Wyoming, and throughout West Michigan, contact AIM Financial to discuss your tax preparation needs.
Do not assume that a foreign trust is exempt from U.S. reporting because it was created abroad or did not distribute money during the year. Reviewing your ownership status and filing responsibilities early can help you address potential issues before deadlines pass.
