Introduction - Why Foreign Gifts and Inheritances Become a US Issue Without Warning

Foreign gifts and inheritances are one of the most anxiety-inducing areas of US tax for internationally mobile families. Not because tax is always due. In many cases, it isn’t. But because the reporting rules are strict, unfamiliar, and unforgiving, and people often only discover them after money or assets have already moved.

Common situations include:

  • an expat receiving money from parents overseas,
  • an inheritance paid from a foreign estate,
  • assets held in a family trust abroad,
  • property or investments gifted before or after a move to the US,
  • long-standing family structures created under non-US legal systems.

From a US perspective, these situations are rarely “informal”. They are governed by specific rules that distinguish between:

  • income,
  • gifts,
  • inheritances,
  • trusts, and
  • reportable foreign transactions.

This guide explains how the US approaches foreign gifts, inheritances, and trusts, focusing on:

  • when US tax applies,
  • when reporting is required even if no tax is due,
  • how foreign family structures are viewed under US rules,
  • why timing and residency matter, and
  • how these issues fit into broader cross-border planning.

This is educational information only, not personalised tax or legal advice. Outcomes depend on individual circumstances, structure, residency, and applicable rules.

What This Guide Helps You Understand

This article is designed for:

  • US citizens living abroad or in the US,
  • foreign nationals who become US tax residents,
  • globally mobile families with cross-border wealth,
  • individuals with foreign family support or inheritances.

Specifically, it helps explain:

  • How the US distinguishes gifts from income and inheritances.
  • When foreign gifts are taxable (and when they are not).
  • Why reporting obligations exist even when no tax is due.
  • How foreign trusts are classified under US rules.
  • What Forms 3520 and 3520-A are designed to capture.
  • How residency changes affect reporting exposure.
  • Why misunderstandings in this area cause disproportionate stress.

We’ll start with the basic distinctions that drive everything else.

How the US Distinguishes Income, Gifts, and Inheritances

From a US tax perspective, classification matters more than the amount.

The IRS draws clear distinctions between:

  • income,
  • gifts, and
  • inheritances.

Income

Generally taxable unless specifically excluded.

Examples:

  • wages,
  • interest,
  • dividends,
  • rental income,
  • business income.

Gifts

Generally not taxable income to the recipient under US rules.

However:

  • gifts may trigger reporting obligations, especially if foreign.

Inheritances

Also generally not taxable income to the recipient.

Again:

  • reporting obligations may apply, particularly for foreign estates or trusts.

This distinction is critical because many people assume:

“If it’s not taxable, I don’t need to report it.”

That assumption is often incorrect.

When Foreign Gifts Become a US Reporting Issue

Foreign gifts are one of the most common triggers for US reporting obligations.

For US tax residents:

  • receiving gifts from foreign individuals or estates may require reporting,
  • even when no US income tax is due.

Key concept

The US is often more concerned with transparency than taxation in this area.

Large foreign gifts can raise questions about:

  • source of funds,
  • classification of income,
  • anti-money laundering concerns,
  • potential trust relationships.

Reporting helps the IRS understand context.

Thresholds for Reporting Foreign Gifts

US tax residents may be required to report foreign gifts when:

  • the total value of gifts from foreign individuals or estates exceeds certain thresholds in a tax year,
  • gifts are received from foreign corporations or partnerships (lower thresholds apply).

These thresholds change over time and must be checked annually.

Important nuance:

  • reporting thresholds are not tax thresholds,
  • crossing the threshold does not automatically mean tax is owed.

This is a reporting issue, not necessarily a tax issue.

Common Sources of Foreign Gifts

Foreign gifts commonly arise from:

  • parents or grandparents living abroad,
  • family support payments,
  • proceeds from family property sales,
  • wedding gifts,
  • inter-generational wealth transfers,
  • informal family arrangements that are common outside the U.S.

From a US perspective, intent matters less than classification and reporting.

Foreign Inheritances Under US Tax Rules

Foreign inheritances are generally not taxable income to the US recipient.

However:

  • reporting may still be required,
  • documentation is important,
  • trust involvement changes the analysis.

Foreign inheritances may include:

  • cash,
  • securities,
  • property,
  • interests in businesses,
  • distributions from foreign trusts.

Each category can trigger different reporting obligations.

Why Foreign Trusts Change Everything

Foreign trusts introduce a different level of complexity.

Under US rules, a trust is classified as:

  • US trust, or
  • foreign trust.

This classification depends on:

  • who controls the trust,
  • where decisions are made,
  • governing law,
  • trustee powers.

Many structures that are not called “trusts” abroad may still be treated as trusts for US tax purposes.

Examples include:

  • family foundations,
  • discretionary family arrangements,
  • offshore holding structures,
  • inheritance planning vehicles created under civil-law systems.

Naming conventions do not control US treatment.

How the US Classifies Foreign Trusts

The US applies two tests:

  • the court test, and
  • the control test.

If either test fails, the trust is treated as a foreign trust.

Foreign trusts are subject to:

  • specific reporting rules,
  • potential income inclusion rules,
  • additional scrutiny.

This is where many compliance problems begin.

Form 3520: Why It Exists

Form 3520 is used to report:

  • large foreign gifts,
  • foreign inheritances,
  • certain transactions with foreign trusts,
  • distributions from foreign trusts.

Important points:

  • filing is informational, not a tax payment by default,
  • penalties for non-filing can be severe,
  • many people are unaware of the form until years later.

Form 3520 is one of the most commonly missed US filings for internationally mobile families.

Form 3520-A: Foreign Trust Reporting

Form 3520-A is generally used to report:

  • foreign trust activity,
  • ownership or beneficiary relationships,
  • trust income and distributions.

It is often:

  • the responsibility of the trust,
  • but can fall to the US person if the trust does not file.

This is an area where coordination matters.

Why Foreign Trust Issues Are Often Discovered Too Late

Foreign gifts and trusts often operate quietly for years.

Problems usually surface when:

  • someone becomes a US tax resident,
  • funds are transferred into US accounts,
  • a trust makes a distribution,
  • inheritance proceeds are received,
  • banks request source-of-funds explanations.

By that point, reporting deadlines may already have passed.

Gifts Received Before vs After Becoming a US Tax Resident

One of the most important distinctions in this area is timing.

Gifts received before US tax residency

If a foreign national receives gifts before becoming a US tax resident:

  • US reporting obligations generally do not apply at the time of receipt
  • The US tax system typically has no visibility into the transaction
  • Documentation may still be important later

However, complications can arise if:

  • funds are transferred into US accounts after residency begins
  • the nature of the funds is questioned by US institutions
  • the gift is connected to an ongoing foreign trust

Gifts received after US tax residency begins

Once an individual is a US tax resident:

  • reporting thresholds apply
  • Form 3520 may be required
  • timing of receipt matters more than intent

The same gift can be treated very differently depending on when residency starts.

Gifts From Individuals vs Gifts From Entities

US rules draw a distinction between gifts received from:

  • foreign individuals or estates, and
  • foreign corporations or partnerships

This distinction matters because:

  • reporting thresholds differ
  • scrutiny levels differ
  • classification issues arise more frequently

Gifts from foreign entities often raise questions about:

  • whether the transfer is truly a gift
  • whether income is being disguised
  • whether a trust relationship exists

Clear documentation is essential.

How Foreign Trust Distributions Are Viewed Under US Rules

Distributions from foreign trusts are not treated the same way as gifts.

Depending on the structure, distributions may be treated as:

  • gifts
  • income
  • return of capital
  • accumulation distributions

The classification affects:

  • whether income tax applies
  • how the distribution is reported
  • whether additional forms are required

This is one of the most complex areas of cross-border tax interaction.

Accumulation Distributions and Why They Matter

Some foreign trusts accumulate income rather than distributing it annually.

When a US person later receives distributions:

  • accumulated income may be taxed
  • interest charges may apply
  • reporting complexity increases

This is often referred to as the “throwback” concept, though application depends on circumstances.

Accumulation issues are rarely obvious without careful review.

Foreign Trusts and Ongoing Income Tax Exposure

Foreign trusts may generate income internally.

Key questions include:

  • is the US person treated as an owner?
  • is income attributed annually?
  • does income flow through to beneficiaries?

The answers depend on:

  • trust terms
  • control provisions
  • distribution rights
  • governing law

Trust income classification is highly fact-specific.

Common Misunderstandings About Foreign Gifts and Trusts

Some frequent assumptions that lead to problems:

  • “It’s a gift, so the IRS doesn’t care.”
  • “My parents live abroad, so US rules don’t apply.”
  • “The trust isn’t called a trust, so it isn’t one.”
  • “I’ll report it later if needed.”
  • “The bank already asked questions, so the IRS won’t.”

These assumptions are often incorrect.

Documentation: The Single Most Important Safeguard

In cross-border gift and inheritance situations, documentation often matters more than tax.

Useful records may include:

  • gift letters
  • wills or probate documents
  • trust deeds
  • bank statements
  • legal correspondence
  • valuation reports

Clear documentation can:

  • support classification
  • reduce uncertainty
  • help respond to questions later

Poor documentation often creates avoidable stress.

How Foreign Gifts and Trusts Interact With Other US Reporting

Foreign gifts and trusts often intersect with:

  • FBAR reporting
  • FATCA Form 8938
  • foreign bank account disclosures
  • source-of-funds reviews by banks

Each reporting regime has a different purpose, but overlap is common.

Why Foreign Trust Issues Often Escalate Quickly

Once an issue is identified:

  • penalties for non-filing can accumulate
  • correction options become more limited
  • voluntary disclosure pathways may be time-sensitive

This is why awareness - not urgency - is the right approach.

Why This Area Requires Early Awareness

Foreign gifts, trusts, and inheritances are rarely one-off events.

They often:

  • recur over time
  • involve family dynamics
  • evolve as circumstances change
  • intersect with estate planning

Understanding the framework early helps prevent problems later.

Hypothetical Cross-Border Family Scenarios

The following scenarios are hypothetical and provided for educational purposes only. They do not represent real clients or outcomes.

Scenario 1 - Family Support From Parents Overseas

A US tax resident receives periodic financial support from parents living outside the United States.

Key considerations:

  • Transfers may be gifts rather than income.
  • Reporting thresholds may apply.
  • Form 3520 may be required.
  • Clear documentation helps support classification.
  • Timing of residency matters.

Scenario 2 - Inheriting Assets From a Foreign Estate

An individual inherits cash and securities from a relative’s estate abroad after becoming a US tax resident.

Key considerations:

  • The inheritance is generally not taxable income.
  • Reporting may still be required.
  • Documentation of the estate and distributions is important.
  • Trust involvement may change the analysis.

Scenario 3 - Distributions From a Long-Standing Family Trust

A US person receives distributions from a family structure created abroad decades earlier.

Key considerations:

  • The structure may be treated as a foreign trust under US rules.
  • Distributions may be classified as income or capital.
  • Accumulation rules may apply.
  • Reporting obligations can be significant.

Scenario 4 - Gifted Property Later Sold

An individual receives foreign property as a gift and later sells it while a US tax resident.

Key considerations:

  • Cost basis may carry over from the donor.
  • Capital gains may be taxable in the U.S.
  • Local tax rules may also apply.
  • Currency effects can materially affect the gain.

Practical Checklist for Foreign Gifts, Trusts, and Inheritances

Before receiving or transferring assets across borders, individuals may wish to confirm:

  • Their US tax residency status.
  • Whether a transfer is a gift, income, or inheritance.
  • Whether the transfer involves a trust or trust-like structure.
  • Applicable reporting thresholds.
  • Which forms may be required (e.g., Form 3520, 3520-A).
  • Availability of documentation supporting classification.
  • How the transfer interacts with other reporting regimes.
  • Potential future implications of repeated transfers.
  • How the transfer fits into broader financial planning.

This checklist helps frame the issue but does not replace professional advice.
