IRS Form 3520 Guide: Foreign Gifts & Foreign Trust Rules

Introduction – What is Form 3520?

Form 3520, officially titled Annual Return To Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts, is an official international information return issued by the Internal Revenue Service (IRS). It is used by United States taxpayers to declare financial transactions involving foreign trusts, as well as large gifts or inheritances received from foreign persons.

The IRS governs Form 3520 under Internal Revenue Code Sections 6039F, 6048, and 671 through 679. Because international financial transactions can be complex, Form 3520 serves as a mandatory disclosure form that allows the IRS to monitor cross-border transfers and offshore assets.

Purpose of the Form

Unlike standard tax returns that calculate income tax owed, Form 3520 is primarily an informational reporting form. In most cases, receiving a foreign gift or inheriting money from overseas is completely tax-free to the U.S. recipient, but the IRS still requires full disclosure.

Form 3520 serves several crucial tax compliance functions:

• It deters tax evasion, money laundering, and offshore wealth hiding through foreign trusts and international gifts.
• It tracks transfers of cash, real estate, or property into foreign trusts created by U.S. persons.
• It reports distributions, loans, or uncompensated asset usage received from foreign trusts.
• It discloses large foreign gifts or inheritances exceeding statutory IRS threshold limits.

Who Needs to File This Form

Form 3520 must be completed by any U.S. person (including U.S. citizens, green card holders, resident aliens, domestic corporations, partnerships, LLCs, estates, or trusts) who engages in reportable international events. You must file Form 3520 if you:

• Received gifts or inheritances totaling more than $100,000 from a foreign individual or foreign estate during the tax year (aggregating all gifts from related foreign donors).
• Received gifts totaling more than the annually adjusted statutory threshold from foreign corporations or foreign partnerships.
• Created a foreign trust or transferred money, property, or assets (directly or indirectly) to a foreign trust.
• Are treated as the owner of any portion of a foreign trust under U.S. grantor trust rules.
• Received a distribution, uncompensated loan, or free use of trust property from a foreign trust during the tax year.

Who Is Exempt / Not Required to File

Form 3520 is not required for every international financial interaction. You are exempt from filing Form 3520 if:

• Gifts Under $100,000: You received foreign gifts or inheritances from foreign individuals totaling $100,000 or less during the tax year.
• Domestic Transfers: Gifts or property transfers exchanged between domestic U.S. citizens or domestic U.S. trusts (reported on Form 709 if gift tax applies).
• Commercial Business Transactions: Fair market value commercial sales or arm’s-length business transactions conducted with foreign trusts.
• Exempt Foreign Retirement Trusts: Tax-favored foreign retirement or pension trusts (such as Canadian RRSPs or RRIFs) that qualify for simplified reporting relief under special IRS revenue procedures.

When to File

Form 3520 follows the annual individual tax filing schedule, but special international deadline rules apply:

• Standard Due Date: Due on the **15th day of the 4th month** following the end of your tax year (April 15 for calendar-year individual taxpayers).
• Expats Living Abroad: U.S. citizens and resident aliens living and working outside the United States on April 15 receive an automatic extension to **June 15**.
• Form 4868 Extension: If you file Form 4868 to extend your main income tax return (Form 1040), your Form 3520 deadline is automatically extended to **October 15**.
• No Late Extensions: Form 3520 cannot be extended beyond October 15.

Where and How to File

Form 3520 is a paper return and must be filed SEPARATELY from your main federal income tax return.

Do not attach Form 3520 to your Form 1040. Mail the original signed Form 3520 directly to the Internal Revenue Service Center address in Ogden, Utah as per official IRS instructions listed on the form. Always use certified mail with return receipt requested to maintain proof of timely filing.

Step-by-Step Instructions to Fill the Form

Form 3520 is a comprehensive four-part form. Taxpayers only complete the specific parts that apply to their international transaction.

Form 3520 Section Breakdown

Form Section	Section Title	Required Information & Instructions
Header	Taxpayer Details	Enter your full legal name, Social Security Number (SSN) or EIN, address, and check applicable filing status boxes.
Part I	Transfers to Foreign Trusts	Report creation of foreign trusts, property transfers, cash contributions, or loans made to a foreign trust during the year.
Part II	U.S. Owner of Foreign Trust	Complete if you are treated as a U.S. owner of a foreign grantor trust under Sections 671–679. Attach Form 3520-A data.

Part IV	Foreign Gifts & Inheritances	Report large gifts or bequests exceeding $100,000 from foreign individuals/estates, listing each individual gift over $5,000.

Required Documents/Information Needed Before Filling

Gather the following financial records and international disclosures before completing Form 3520:

• Full legal names, street addresses, and countries of citizenship for foreign donors or foreign trustees.
• Exact dates and U.S. dollar values (converted at official IRS exchange rates) for all foreign gifts, inheritances, or trust distributions received.
• Foreign Trust Statements (Foreign Grantor Trust Statement or Foreign Non-Grantor Trust Statement) issued by foreign trustees.
• Independent appraisal reports or fair market value valuation records for non-cash property or real estate received.

Common Mistakes to Avoid

Errors or omissions on Form 3520 can result in automated, severe IRS penalty assessments. Avoid these common mistakes:

• Attaching Form 3520 to Form 1040: Mailing Form 3520 together with your annual Form 1040 tax return. Form 3520 must be mailed separately to the IRS Ogden, Utah service center.
• Failing to Aggregate Related Gifts: Treating gifts from related foreign family members as separate small gifts. Gifts received from related foreign individuals (e.g., $60,000 from a foreign mother and $50,000 from a foreign father) must be aggregated. Because the combined total ($110,000) exceeds $100,000, Form 3520 is required.
• Assuming Foreign Gifts Are Taxed: Believing that reporting a foreign gift on Form 3520 will create an income tax bill. Foreign gifts are non-taxable disclosures; the form is strictly informational.
• Ignoring Rent-Free Property Usage: Failing to report the uncompensated use of real estate or assets owned by a foreign trust. The IRS treats rent-free use of trust property as a reportable trust distribution.

Penalties for Non-Filing or Errors

Form 3520 carries some of the most aggressive automatic penalties in the entire Internal Revenue Code:

• Foreign Gift Penalties (IRC Section 6039F): The penalty for failing to report a foreign gift is 5% of the gift amount for each month the return is late, capping at a maximum penalty of 25% of the total gift amount.
• Foreign Trust Distribution Penalties (IRC Section 6677): Failing to report foreign trust distributions triggers an initial penalty equal to 35% of the gross value of the distribution (or $10,000, whichever is greater).
• Foreign Trust Transfer Penalties: Failing to report property transferred to a foreign trust triggers a penalty equal to 35% of the gross value of the transferred property.

Frequently Asked Questions

Are foreign gifts or inheritances taxed when reported on Form 3520?

No. Under federal tax law (IRC Section 102), gifts and inheritances received from foreign individuals are excluded from gross income and are not subject to U.S. income tax. Form 3520 is an informational disclosure return, not a tax assessment form.

What is the threshold for reporting a gift from a foreign individual?

You must file Form 3520 (Part IV) if the aggregate value of gifts or inheritances received from a nonresident alien individual or foreign estate exceeds $100,000 during the tax year.

Should Form 3520 be attached to Form 1040?

No. Do not attach Form 3520 to your Form 1040. You must mail Form 3520 as a separate document to the IRS service center in Ogden, Utah.

What happens if I receive multiple gifts under $100,000 from related foreign donors?

The IRS requires you to aggregate gifts from foreign donors you know (or have reason to know) are related. If the combined total from related donors exceeds $100,000 during the year, you must report all gifts on Form 3520.

What is the penalty for filing Form 3520 late?

For late reporting of foreign gifts, the penalty is 5% of the gift amount for every month the form is late, up to a maximum of 25%. For unreported foreign trust distributions or transfers, the penalty is 35% of the gross amount.

What is the difference between Form 3520 and Form 3520-A?

Form 3520 is filed by the U.S. person who receives a foreign gift, makes a trust transfer, or receives a trust distribution. Form 3520-A is an annual administrative return filed by the foreign trust itself if it has a U.S. owner.
