IRS Form 3520-A – In an increasingly globalized world, many U.S. taxpayers find themselves involved with foreign trusts, whether through international investments, family estate planning, or expatriate living. If you’re a U.S. owner of a foreign trust, complying with IRS reporting requirements is crucial to avoid hefty penalties. One key form in this process is IRS Form 3520-A, the Annual Information Return of Foreign Trust With a U.S. Owner. This comprehensive guide breaks down everything you need to know about Form 3520-A, including its purpose, filing requirements, deadlines, and potential pitfalls. Whether you’re an expat, a trustee, or a tax professional, understanding this form can help ensure smooth compliance with U.S. tax laws.
What Is IRS Form 3520-A?
IRS Form 3520-A is an annual information return that foreign trusts with at least one U.S. owner must file to report details about the trust’s operations, income, distributions, and beneficiaries. The form provides transparency to the IRS regarding the trust’s activities, ensuring that U.S. owners report their attributable income correctly on their personal tax returns. Unlike income tax returns, Form 3520-A is purely informational and does not calculate or pay taxes—it simply discloses the trust’s financials under U.S. tax principles.
The form consists of several parts:
- Part I: General Information – Includes the trust’s name, Employer Identification Number (EIN), address, creation date, and details about any appointed U.S. agent.
- Part II: Foreign Trust Income Statement – Reports income sources like interest, dividends, rents, and capital gains, along with expenses such as taxes, fees, and charitable contributions. It also details distributions to U.S. owners and beneficiaries, including fair market values (FMV).
- Part III: Foreign Trust Balance Sheet – Provides a snapshot of assets, liabilities, and net worth at the beginning and end of the tax year, valued at FMV.
- Attached Statements – Includes Foreign Grantor Trust Owner Statements (for each U.S. owner) and Foreign Grantor Trust Beneficiary Statements (for U.S. beneficiaries who received distributions). These statements outline attributable income, distributions, and ownership explanations under U.S. grantor trust rules (Internal Revenue Code sections 671–679).
All information must be reported in English and U.S. dollars, based on the trust’s books and records. If no U.S. agent is appointed, additional documents like trust instruments or organizational charts may need to be attached.
Who Must File Form 3520-A?
The primary filer is the foreign trust itself if it has a U.S. owner under the grantor trust rules. However, each U.S. person treated as an owner is responsible for ensuring the form is filed and that required statements are provided to owners and beneficiaries. If the foreign trust fails to file, the U.S. owner must submit a “substitute” Form 3520-A attached to their own Form 3520 (Annual Return To Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts).
Exceptions include certain Canadian registered retirement savings plans (RRSPs) or registered retirement income funds (RRIFs) under Revenue Procedure 2014-55, and eligible tax-favored foreign trusts for retirement, medical, disability, or educational purposes under Revenue Procedure 2020-17 and proposed regulations (applicable for tax years after May 8, 2024). These exemptions do not apply to other reporting obligations like Form 8938 (Statement of Specified Foreign Financial Assets) or FinCEN Form 114 (FBAR).
U.S. beneficiaries who receive distributions from the trust may also need to report on Form 3520, but Form 3520-A focuses on the trust’s overall reporting.
When and How to File IRS Form 3520-A?
Form 3520-A is due by the 15th day of the third month following the end of the foreign trust’s tax year—typically March 15 for calendar-year trusts. For substitute forms filed by U.S. owners, the deadline aligns with Form 3520, which is generally the 15th day of the fourth month after the U.S. owner’s tax year end (e.g., April 15 for individuals).
To extend the deadline, file Form 7004 (Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns) by the original due date. This grants an extension for Form 3520-A but not for individual income tax returns.
File the form by mail to the IRS Center, P.O. Box 409101, Ogden, UT 84409. The trustee (or U.S. owner for substitutes) must sign under penalties of perjury. Provide copies of the Owner and Beneficiary Statements to the respective U.S. parties by the filing deadline.

Key Information Required on Form 3520-A
Completing Form 3520-A requires detailed financial data:
- Income and Expenses: Report all sources, including taxable interest, dividends (qualified and ordinary), partnership income, capital gains/losses, and other income. Deduct expenses like foreign taxes, depreciation, trustee fees, and charitable contributions.
- Distributions: Detail any transfers to U.S. persons, including cash, property, loans, or uncompensated use of trust assets. Include recipient names, Taxpayer Identification Numbers (TINs), dates, descriptions, and FMVs.
- Balance Sheet: List assets (e.g., cash, securities, real estate) and liabilities at FMV, without needing to reconcile to book values.
- Ownership Details: Explain why the trust is treated as grantor-owned under U.S. tax law, citing relevant IRC sections.
Attach statements for “other” items and, if no U.S. agent, copies of trust documents (or updates if previously filed within three years).
Penalties for Not Filing Form 3520-A
Non-compliance can be costly. The U.S. owner is liable for a penalty of the greater of $10,000 or 5% of the gross value of the portion of the trust they own at year-end if the form is late, incomplete, or incorrect. Additional penalties apply if noncompliance continues more than 90 days after IRS notification. Criminal penalties may arise for willful failures or false statements (sections 7203, 7206, 7207), and accuracy-related penalties up to 40% for underpayments tied to undisclosed foreign assets (section 6662(j)).
Reasonable cause can waive penalties, but reliance on foreign advisors or the trust’s reluctance doesn’t qualify. The IRS has ramped up focus on foreign trust reporting, including Form 3520-A, with recent announcements and practice units aimed at educating taxpayers and examiners.
Recent Updates to Form 3520-A as of 2026
As of February 2026, the instructions emphasize using the continuous-use revision for tax year 2025 and beyond until superseded. Key reminders include entering the tax year on all pages and statements, and noting the calendar year for fiscal-year trusts. The IRS continues to highlight the substitute filing option and extensions via Form 7004. For developments, check IRS.gov/Form3520A regularly, as legislation post-publication may affect requirements. Recent IRS campaigns target non-filers, with updated announcements in 2025 stressing compliance for U.S. owners of foreign grantor trusts.
