Form 3520-A: Annual Information Return of Foreign Trust With a U.S. Owner
Complete guide to Form 3520-A for US expats who are treated as owners of foreign trusts. Learn the grantor trust rules, annual filing requirements, and how to avoid the $10,000 failure-to-file penalty.
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:
- Created or funded the trust and retained a reversionary interest worth more than 5% of the trust value
- Retained the power to revoke the trust or revest title in themselves
- Retained the power to control beneficial enjoyment — who receives income or principal
- Retained administrative powers exercisable for their own benefit (e.g., borrowing trust income without adequate interest)
- 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
| Violation | Penalty |
|---|---|
| Failure to file | Greater of $10,000 or 35% of gross reportable amount |
| Failure to provide beneficiary statements | $10,000 per beneficiary |
| Inaccurate filing | $10,000 or 35% of underreported amount |
| Fraudulent filing | 75% of underpayment |
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.
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.

Frequently Asked Questions
Who must file Form 3520-A?
You must file Form 3520-A if you are a US person treated as the owner of a foreign trust under the grantor trust rules (IRC Sections 671-679). This generally applies if you created or funded a foreign trust and retained certain powers such as revocation, control over beneficial enjoyment, or a reversionary interest.
What is the difference between Form 3520 and Form 3520-A?
Form 3520 is event-driven — filed when you receive foreign gifts over $100,000, receive trust distributions, or transfer assets to a foreign trust. Form 3520-A is annual — filed every year by the owner of a foreign trust to report the trust's income, deductions, and distributions.
What is the penalty for not filing Form 3520-A?
The penalty for failure to file Form 3520-A is the greater of $10,000 or 35% of the gross reportable amount. Because it is an annual form, penalties compound quickly if multiple years are missed.
When is Form 3520-A due?
Form 3520-A is due on March 15 if the trust files separately, or with your personal tax return (April 15, June 15 for expats, or October 15 with extension) if you attach it to your Form 1040.
Do foreign pensions require Form 3520-A?
Some foreign pension structures may be treated as trusts under US tax principles. If you are the owner of a foreign pension trust (for example, the subscriber of a Canadian RESP), you may need to file Form 3520-A. The analysis is complex and fact-specific.
