What Is IRS Form 3520 and Its Purpose?
IRS Form 3520 is an information return used by U.S. persons to disclose specific transactions with foreign trusts and the receipt of large foreign gifts or bequests. It’s not a tax payment form but rather a reporting tool to help the IRS monitor potential tax avoidance through offshore entities. The form applies to activities under Internal Revenue Code sections 671 through 679, which deal with grantor trusts and ownership rules.
Key purposes include:
- Reporting creations, transfers, or ownership of foreign trusts.
- Disclosing distributions or loans from foreign trusts.
- Notifying the IRS of gifts or bequests exceeding certain thresholds from foreign individuals, estates, corporations, or partnerships.
Unlike income tax returns, Form 3520 must be filed separately, even if no tax is due. It’s essential for maintaining transparency in international dealings and avoiding penalties under sections 6039F and 6677.
Who Must File IRS Form 3520?
Not every U.S. taxpayer needs to file Form 3520—it’s targeted at those with specific foreign interactions. You must file if you’re a U.S. person (including citizens, residents, domestic partnerships, corporations, estates, or trusts) and any of the following apply during your tax year:
- Reportable Events with Foreign Trusts: You created a foreign trust, transferred money or property to one (including by death), or are the executor of a U.S. decedent’s estate involved in such transfers.
- Ownership of Foreign Trusts: You’re treated as the owner of any portion of a foreign trust under grantor trust rules (sections 671-679).
- Distributions from Foreign Trusts: You received distributions, loans, or uncompensated use of property from a foreign trust (directly or indirectly).
- Foreign Gifts or Bequests: You received gifts or bequests totaling more than $100,000 from a nonresident alien or foreign estate, or exceeding thresholds from foreign corporations/partnerships (adjusted annually for inflation—check IRS guidelines for current amounts).
Exceptions include fair market value (FMV) transfers (with caveats for obligations or appreciated property), certain deferred compensation plans, and tax-favored foreign retirement trusts under specific revenue procedures. A separate Form 3520 is required for each foreign trust.
If you’re the U.S. owner of a foreign trust, you may also need to ensure the trust files Form 3520-A (Annual Information Return of Foreign Trust With a U.S. Owner) or attach a substitute to your Form 3520.
Key Reporting Requirements for Form 3520
Form 3520 is divided into four parts, each addressing different aspects of foreign trust and gift reporting. Here’s a breakdown:
Part I: Transfers to Foreign Trusts
Report any “reportable events,” such as creating a foreign trust or transferring property/cash. Include:
- Details on the trust creator, country code, and transfer date.
- FMV, adjusted basis, and gain recognized on transferred property.
- Information on qualified obligations (loans meeting specific criteria like ≤5-year term and interest rates between 100-130% of the applicable federal rate).
Use Schedules A, B, and C for obligations, gratuitous transfers, and outstanding qualified obligations.
Part II: U.S. Ownership of Foreign Trusts
If you’re treated as the owner under grantor rules, disclose:
- The owner’s details, country codes, and creation date.
- Gross value of the owned portion at year-end.
- Attach a Foreign Grantor Trust Owner Statement or substitute Form 3520-A if the trust didn’t file one.
Part III: Distributions from Foreign Trusts
Report all distributions, including cash, property, loans, or uncompensated use (treated as distributions). Provide:
- Dates, descriptions, and FMV.
- Whether beneficiary statements were received (Foreign Grantor or Nongrantor Trust Beneficiary Statements).
- Calculations for accumulation distributions using default (Schedule A) or actual (Schedule B) methods, plus interest charges (Schedule C) via Form 4970.
Part IV: Foreign Gifts and Bequests
Disclose gifts/bequests exceeding thresholds:
- Dates, descriptions, and FMV.
- Donor details (name, address, TIN if available).
- Aggregate amounts from related donors.
Additional requirements include appointing a U.S. agent for the trust (if no agent, provide beneficiary/trustee details) and attaching trust documents or summaries.

- For Foreign Gifts (Section 6039F): 5% per month (up to 25%) of the unreported amount.
- Accuracy-Related Penalties (Section 6662(j)): 20-40% on underpayments due to undisclosed foreign financial assets.
- Extended Assessment Period: Late or incomplete filing extends the statute of limitations by 3 years under section 6501(c)(8).
Reasonable cause may waive penalties if the failure wasn’t willful. However, ignorance isn’t an excuse—consult a tax professional for complex situations.
Recent Updates to Form 3520 as of 2026
As of February 2026, the IRS has updated instructions for Form 3520 (Rev. December 2025) to clarify definitions, such as “distribution” (now including constructive transfers like credit card payments) and “qualified obligations.” There’s emphasis on reporting inconsistencies via Form 8082 and expanded exceptions for certain foreign retirement trusts under proposed regulations. No major structural changes from prior years, but inflation adjustments may affect gift thresholds—check IRS.gov for the latest.
U.S. owners should note reminders about coordinating with Form 3520-A filings, due March 15 (or with extensions). Always verify updates at IRS.gov/Form3520, as legislation post-publication could impact requirements.
