IRS Form 3520-Reporting Transactions With Foreign Trusts

If you’re reading this article, you might be wondering if you need to file IRS Form 3520. This probably is because you’ve either:

  • Received money, assets, or property from a foreign source, or
  • Transferred money, assets, or property to a foreign source

This in-depth article will serve as a guide for the most commonly asked questions about this form, including:

Let’s begin with an overview on what IRS Form 3520 actually is.

What is IRS Form 3520?

IRS Form 3520 is known as the Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts. It is an informational form that certain individuals, trusts, or entities, must file with the Internal Revenue Service.

According to the IRS website, Form 3520 reports the following types of information:

  • Certain transactions with foreign trusts,
  • Ownership of foreign trusts under the rules of sections 671 through 679, and
  • Receipt of certain large gifts or bequests from certain foreign persons.

However, not everyone who interacts with a foreign person is required to file this form.

Who must file IRS Form 3520?

According to the IRS, you must file Form 3520 if any of the following apply:

You are a responsible party reporting a reportable event that occurred during the current tax year.

This brings up two important questions:

  • What is a responsible party?
  • What is a reportable event?

Responsible party

A responsible party is defined as any one of the following:

  • The grantor or creator of an inter vivos trust. An inter vivos trust, also known as a living trust, is a trust created by one living person for the benefit of another person.
  • The transferor in the case of a reportable event.
  • The executor of the decedent’s estate in any case (whether the executor is a US citizen or not)

Anyone meeting the definition of a responsible party must report any reportable event on Form 3520. So what is a reportable event?

Reportable event

A reportable event is defined as one of the following:

  • A United States person creating a foreign trust
  • The transfer of property by a U.S. person into a foreign trust. This can be a direct transfer or indirect transfer, and includes transfers upon death.
  • The death of a U.S. citizen or resident if:
    • The decedent was considered the owner of any part of a foreign trust under the rules of the Internal Revenue Code, Sections 671 through 679, or
    • Any part of a foreign trust was included in the decedent’s gross estate

Even if you’re not a responsible party reporting a reportable event, you may still be required to file this form, especially if you transferred property to a foreign trust.

If this is true, the IRS expects you to complete the identifying information on page 1 and applicable portions of Part I of this form.

You are a US person who transferred property to a foreign trust in exchange for an obligation.

Or if you currently hold an outstanding qualified obligation from the foreign trust. There is also an IRS definition of what a qualified obligation is.

What is a qualified obligation?

For purposes of completing this tax form, a qualified obligation is one that:

  • Is in writing
  • Does not exceed 5 years
  • Is in U.S. dollars
  • Has a yield to maturity (YTM) of at least 100% of the applicable federal rate, but not more than 130% of the federal rate on the date issued
  • The U.S. person agrees to extend the period of assessment of any income or transfer tax attributable to the transfer and any consequential income tax changes for each year to a date at least 3 years after the maturity date. The exception exists if the maturity date does not go past the end of the U.S. person’s tax year and is paid within such period.
  • The U.S. person reports the status of the obligation every year that it is outstanding

If applies to you, the IRS expects you to complete the identifying information on page 1 and applicable portions of Part I of this form.

You are a U.S. person who is treated as the owner of any part of the assets of the foreign trust.

If this is your situation, the IRS expects you to complete the identifying information on page 1 and applicable portions of Part II of this form.

You are a U.S. person who received a distribution from a foreign trust during the tax year.

Filing this form is mandatory if you received a distribution from a foreign trust. You also must file this form if any of the following apply:

  • You received a loan of cash or marketable securities during the year. This also includes lines of credit.
  • You received the uncompensated use of property owned by a foreign trust.
  • If you are the U.S. owner or beneficiary of a foreign trust, and the foreign trust holds an outstanding qualified obligation of yours

If any of these apply to you, you’ll have to complete the identifying information on page 1 and applicable portions of Part III of this form.

You are a U.S. person who received above a certain amount from foreign sources

Filing this form is either of the following apply:

  • You received $100,000 or more in gifts from a nonresident alien individual or foreign estate that you treated as gifts or bequests. This includes related foreign persons.
  • You received more than a certain amount from a foreign corporation or a foreign partnership. This is known as the IRC Section 6039F threshold. For 2021, the 6039F threshold is $16,815.

When is IRS Form 3520 due?
