Form 3520-A: Annual Information Return of Foreign Trust With a U.S. Owner

Form 3520-A is the annual information return for US persons who own foreign trusts. While Form 3520 captures individual events — gifts, distributions, transfers — Form 3520-A is the ongoing annual report card for the trust itself. If you created or funded a foreign trust and still retain certain powers over it, you are likely required to file this form every year. The penalty for missing it is severe: $10,000 or 35% of the trust's value, whichever is greater.

Who Must File Form 3520-A?

You must file Form 3520-A if you are a US person who is treated as the owner of a foreign trust under the grantor trust rules (IRC Sections 671-679).

Grantor Trust Rules

A US person is treated as the owner of a foreign trust if they:

1. Created or funded the trust and retained a reversionary interest worth more than 5% of the trust value
2. Retained the power to revoke the trust or revest title in themselves
3. Retained the power to control beneficial enjoyment — who receives income or principal
4. Retained administrative powers exercisable for their own benefit (e.g., borrowing trust income without adequate interest)
5. Is the beneficiary and another person contributed property to the trust on their behalf

Examples of Foreign Trust Owners

• You set up an offshore asset protection trust in Belize and retained the power to revoke it
• You funded a family trust in the UK for your children but kept the right to change beneficiaries
• You are the subscriber of a Canadian RESP (the subscriber is generally treated as the owner)
• You established a foreign charitable remainder trust and retained an income interest

Not owners: Beneficiaries who merely receive distributions but did not create or fund the trust and have no control powers.

What Information Does Form 3520-A Require?

Form 3520-A requires detailed trust financial information:

Part I: General Information

• Trust name, address, country of organization
• US owner's name, address, TIN
• US agent (if any) appointed to receive IRS notices
• Trust type (discretionary, accumulation, etc.)

Part II: Foreign Trust Income Statement

• Gross income by category (interest, dividends, capital gains, rents, royalties, business income)
• Deductions directly connected to income production
• Net income

Part III: Foreign Trust Balance Sheet

• Assets at beginning and end of year (cash, investments, real estate, other)
• Liabilities
• Trust corpus and accumulated income

Part IV: Distributions to US Beneficiaries

• Names and addresses of US beneficiaries who received distributions
• Amount and character of distributions (income, corpus, etc.)

Part V: Foreign Grantor Statement

• A statement provided to each US beneficiary showing their share of trust income and deductions
• This statement is used by beneficiaries to report income on their personal returns

Filing Deadlines and Penalties

When to File

• March 15 if the trust files separately with its own US agent
• With your personal tax return (April 15, June 15 for expats, or October 15 with extension) if you attach it to Form 1040

Extension

You can request a 6-month extension (to September 15 for separate filing, or with your personal extension) by filing Form 7004.

Penalties

Important: The 35% penalty is based on the gross value of the trust, not just the income. For a trust with $500,000 in assets, the penalty could be $175,000 per year.

Special Situations

Canadian RESPs

Canadian Registered Education Savings Plans (RESPs) are a common trigger for Form 3520-A:

• The subscriber (person who opens and contributes to the RESP) is treated as the owner of the trust
• The subscriber must file Form 3520-A annually
• The beneficiary (child) does not file Form 3520-A but may need to report income distributions
• Income earned in the RESP is currently taxable to the subscriber, even if not distributed

Exception: If the subscriber is a non-US person and the beneficiary is a US person, different rules may apply.

A Practical Form 3520-A Workflow

Form 3520-A depends on the trust’s legal terms and accounting, not merely on the account balance. Start by obtaining the trust deed, amendments, trustee details, governing law, beneficiary schedule, annual financial statements, contribution history, distribution ledger, and any local tax filing. Identify the person treated as the US owner under the grantor trust rules and determine whether the trustee can provide the information statement that must be furnished to US beneficiaries.

Separate owner, trustee, and beneficiary responsibilities

The trust itself is the reporting subject, but a US owner may have to file a substitute Form 3520-A when the trustee does not. Beneficiaries may also have separate Form 3520 obligations for distributions or other reportable transactions. Build a responsibility chart showing who controls the trust, who contributed assets, who receives distributions, who signs the return, and who has access to the records. The same person can have more than one role, and a different answer may apply after a move, marriage, death, or amendment.

Reconcile trust accounts to US tax categories

Local trust accounts often use categories that do not map directly to US tax reporting. Classify interest, dividends, rent, business income, capital gains, expenses, trustee fees, contributions, and distributions under US principles. Document exchange rates and the treatment of property transferred in kind. If the trust owns a company, fund, pension product, or real estate, evaluate whether additional international forms are needed rather than placing all activity into one summary line.

Substitute filing and reasonable cause

If the foreign trustee fails to file, the US owner may need to attach a substitute Form 3520-A to the owner’s Form 1040 and provide the required information to beneficiaries. That is not a reason to recreate numbers casually. Preserve the trustee’s requests, unanswered emails, available statements, and a schedule showing how the reported amounts were calculated. If a prior year was missed, separate missing information from a disagreement about classification and address each year deliberately.

Planning before funding or distributing

Before transferring more assets, changing trustees, adding beneficiaries, taking a distribution, or closing the trust, obtain a US tax review. A transaction that is ordinary under local law can create a US transfer, owner, distribution, or information-reporting issue. The best time to identify the reporting owner and document the trust’s books is before the next annual filing, not after an IRS notice.

Offshore Asset Protection Trusts

Asset protection trusts in jurisdictions like Belize, Cook Islands, or Nevis are almost always foreign trusts. If you:

• Funded the trust
• Retained any powers (even indirect powers through a protector)
• Are a beneficiary

You likely must file Form 3520-A. Many trust structures are designed to avoid grantor trust status, but the IRS applies a broad facts-and-circumstances test.

Foreign Business Trusts

Trusts used to hold foreign business interests may also trigger Form 3520-A. If you transferred business shares to a foreign trust and retained management powers or income rights, you are likely the owner.

Trusts holding investment accounts

A foreign trust that holds a brokerage account can create several layers of analysis. Identify the trust owner first, then review the account’s investments, income, distributions, and reporting statements. A trust may hold foreign funds that raise PFIC questions, a foreign corporation that raises Form 5471 or Form 8858 questions, or accounts that must be mapped to Form 8938 and the FBAR. Do not assume that reporting the trust balance alone reports the underlying assets.

Changes during the year

Track every event that could change ownership or reporting: a contribution, loan, distribution, beneficiary change, trustee resignation, protector appointment, amendment, migration of governing law, or transfer to another trust. The answer can change when a US person moves abroad or a foreign person becomes a beneficiary. Keep dated copies of amendments and trustee correspondence, even when no cash moved.

Information statements for beneficiaries

Beneficiary statements should identify the distribution, the trust’s income and deductions where required, the beneficiary’s share, and any other information needed for the beneficiary’s Form 3520. If the trustee supplies only a bank statement, request a formal accounting or document the limitation. A missing statement may require a substitute filing and a more cautious distribution analysis; it should not be filled with unsupported estimates.
