Foreign Gift and Inheritance Reporting Obligations
Fund managers receiving large gifts or inheritances from overseas family often discover too late that Form 3520 reporting is required. Whether you're inheriting a family business from parents in Europe, receiving a substantial gift from relatives abroad, or benefiting from a family trust distribution, the IRS expects Form 3520 reporting. Understanding the obligations and engaging specialists in HNW Estate & Trust Planning is the first step toward compliance. The consequences of missing Form 3520 filings range from penalties of $10,000 per year to potential criminal exposure if the IRS determines the failure was willful.
Furthermore, for high-net-worth fund managers, the amounts involved are often substantial — inheritances of £500,000 or gifts of £200,000 are not uncommon. These sizeable amounts attract IRS scrutiny and create meaningful penalties if Form 3520 is missed. A properly prepared HNW Estate & Trust Planning strategy ensures that gifts and inheritances are reported correctly and that the fund manager retains all available tax benefits of the receipt.
Form 3520 Requirements Explained
When Form 3520 Must Be Filed
Form 3520, Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts, must be filed by any US person who receives a foreign gift or inheritance exceeding $100,000 in any year. The threshold is surprisingly low — a single gift of £70,000 plus an additional £35,000 inheritance from the same source in the same calendar year triggers the requirement. The filing is due on the same date as your income tax return, including extensions.
A foreign gift includes any transfer of property from a non-US person or foreign estate to a US person. This covers outright gifts from family members, distributions from foreign trusts, inheritances from foreign estates, and even certain distributions of appreciated securities. The IRS provides detailed Form 3520 guidance at https://www.irs.gov/forms-pubs/about-form-3520. Additionally, if the gift is received from a foreign trust, separate Form 3520-A reporting is required from the trust itself.
The $100,000 Threshold and Aggregation
The $100,000 threshold is the annual aggregate of all foreign gifts received from all sources combined. Gifts from multiple family members or multiple sources are added together. A £50,000 gift from your mother plus a £55,000 inheritance from your uncle in the same year = £105,000 aggregate = Form 3520 required. The rule applies calendar year by calendar year, so a £50,000 gift in December combined with a £55,000 inheritance in January of the following year is treated as two separate years and may not trigger reporting depending on the December timing.
For high-net-worth fund managers, it's common to receive substantial gifts or inheritances that exceed the threshold. A father's decision to gift shares of a family business worth £150,000 to a fund manager son definitely triggers Form 3520. The AICPA guides foreign gift compliance at https://www.aicpa.org/intlacc.
Penalties for Missing Form 3520
The $10,000 Penalty Per Year
The IRS imposes a $10,000 penalty for each Form 3520 that is not filed. This is a strict liability penalty — meaning the IRS can assess it even if the failure was entirely innocent and the taxpayer had no intent to evade tax. A fund manager who misses Form 3520 reporting for a foreign inheritance faces a $10,000 penalty per year for each year of non-compliance.
For a fund manager who received a substantial inheritance in 2020 and never filed Form 3520, the penalty exposure is $60,000 if the omission spans 2020–2022 (three years of missing filings). If the IRS later sends a notice requiring the missing form and the fund manager doesn't comply within 90 days, the penalty increases to $50,000 for continued non-compliance. These penalties can quickly overwhelm the value of the gift itself.
Additional Consequences Beyond Penalties
Beyond monetary penalties, missing Form 3520 filings can trigger an IRS examination of your entire tax return for the year the gift was received. The IRS views unreported foreign gifts as a red flag for potential money laundering, unreported foreign accounts, or other compliance issues. Once an examination opens, the agent may expand the inquiry to multiple years and multiple issues.

Real Scenario: An Inheritance Catch-Up
How We Resolved Three Years of Missing Reporting
We recently assisted a US fund manager in London who inherited approximately £800,000 from a deceased relative's UK estate in 2021. The inheritance was distributed across multiple payments over three years — £250,000 in 2021, £300,000 in 2022, and £250,000 in 2023. Because each year's amount exceeded the $100,000 threshold individually, Form 3520 should have been filed for all three years. The fund manager had never filed any of the three forms.
The theoretical penalty exposure exceeded $30,000 based on three years of missing Form 3520 filings. Through a carefully structured catch-up filing coordinated with our HNW Estate & Trust Planning team, we prepared all delinquent Form 3520 returns documenting the inheritance distribution, the foreign estate source, and the fair market values of the inherited property. We submitted a detailed statement explaining the oversight and supporting documentation showing good-faith receipt of the inheritance. FinCEN provides details on related foreign account reporting at https://www.fincen.gov/report-foreign-bank-and-financial-accounts. The IRS processed the catch-up filings and agreed to waive penalties based on the reasonable cause explanation. All three years of filings are now current.
Common Mistakes With Foreign Gift Reporting
Errors That Create Penalty Exposure
Failing to recognize that an inheritance triggers Form 3520 is the primary error. Many fund managers treat inheritances as non-taxable personal property and fail to consider US reporting requirements separate from UK probate.
Assuming gifts to multiple recipients are separate misses the aggregation rule. If your mother gifts £50,000 to you and £60,000 to your sibling in the same year, only your £50,000 triggers Form 3520 personally — but if the gift is to you and your sibling jointly or to a trust for both, aggregation rules apply.
Not realizing that foreign trust distributions count as gifts can lead to missed filings. If you receive a distribution from a foreign family trust, that distribution may trigger Form 3520 reporting even if other family members established the trust. The ICAEW guides https://www.icaew.com/technical/tax.
Missing the FBAR requirement for inherited bank accounts creates a critical compliance gap. If the inheritance includes foreign bank accounts and you take control of them, those accounts must appear on FinCEN Form 114. The State Department provides information on obligations at https://www.state.gov/american-citizens-abroad/.
Not documenting the fair market value of inherited property makes it difficult to file Form 3520 accurately later. Obtain valuations and estate documents contemporaneously with receipt of the inheritance, not years later when memories fade, and documents are lost.
Strategic Planning for Large Gifts and Inheritances
Coordination With Overall Tax Planning
For high-net-worth fund managers, receipt of a substantial foreign gift or inheritance requires coordination across multiple tax areas. If the inherited property includes foreign real estate, foreign retirement accounts, or foreign securities, each component triggers separate reporting requirements. Form 3520 is just one piece of a comprehensive international tax compliance picture. Guidance on international wealth transfer is available at https://www.investopedia.com/terms/g/gift.asp. The IRS provides detailed inheritance guidance at https://www.irs.gov/publications/p559.
Proper HNW Estate & Trust Planning strategy considers whether the inherited asset should be held individually or through a trust, whether elected reporting status (like QEF for foreign funds) should be made prospectively, and whether FEIE elections (if any) interact with the inheritance receipt. Additional resources on estate planning are at https://www.irs.gov/individuals/international-taxpayers. Coordinating all these elements requires specialist expertise from advisers familiar with both estate planning and international tax.
