Foreign Trust Form 3520: Reporting Transactions, Gifts, and Foreign Inheritance

What Form 3520 Reports

Form 3520 is the IRS reporting form for: (a) US persons’ transactions with foreign trusts, (b) large gifts/bequests from foreign persons, and (c) ownership of foreign trusts.

Four reportable events:

1. Creation of, or transfer of property to, a foreign trust (Part I).

2. US owner of a foreign trust (Part II).

3. Distribution received from a foreign trust (Part III).

4. Receipt of large gifts or bequests from foreign persons (Part IV).

Form 3520 is informational — typically doesn’t generate tax liability directly. But income from the trust (distributions, deemed distributions) may be taxable separately on Form 1040.

Form 3520-A: separate form filed BY the foreign trust (or by US owner if trust doesn’t file). Provides detailed trust financial information.

Due dates:

Form 3520: due with annual tax return (April 15, with extension to October 15).

Form 3520-A: due March 15 of year following (extension to September 15 available on Form 7004).

Penalties for non-filing:

Greater of $10,000 OR 35% of unreported amount (for distributions and transfers to foreign trusts).

Greater of $10,000 OR 5% of foreign trust assets (for ownership reporting failure).

Continued failure: additional $10K per month after notice (up to maximum).

These are the steepest penalties in the international tax compliance landscape.

Foreign Trust Definition

IRC §7701(a)(31) defines foreign trust: a trust that is NOT a domestic trust.

Domestic trust: meets both:

1. Court test: a US court can exercise primary supervision over trust administration.

2. Control test: one or more US persons have authority to control all substantial decisions.

If trust fails either test: foreign trust.

Common foreign trust scenarios:

1. Trust established in foreign country with foreign trustee. Court in that country supervises.

2. Trust established in US but trustee/control is foreign-based.

3. Mexican family trust holding family business.

4. UK ‘discretionary trust’ with UK trustees.

5. Swiss or Liechtenstein private foundation (treated as trust for US tax).

Common US person interactions with foreign trusts:

– US person as beneficiary of foreign family trust (grandparents’ or parents’ trust in home country) – US person establishing foreign trust for asset protection or estate planning – US person inheriting from foreign trust – US person receiving distributions from foreign trust

Reporting required: even mere beneficiary status (without current distribution) may not require Form 3520 in given year, but distributions and other events do.

Active engagement with foreign trust: substantial reporting obligation.

Part I: Transfers to Foreign Trusts

When a US person transfers property to a foreign trust, Form 3520 Part I reports the transfer.

Required:

– Date of transfer – Description of property – FMV at transfer – Trust information

Tax consequences:

Under IRC §684: a transfer to a foreign trust by a US person is generally a deemed sale, triggering gain recognition.

Effect: US person recognizes gain (or loss) on transferred property as if sold at FMV.

Exception: transfers to foreign grantor trust where US grantor is treated as owner — typically no gain recognition.

Penalty for failure to file Part I: greater of $10K or 35% of FMV of transfer.

For $1M transfer: minimum $10K penalty (but could be $350K if 35% applies).

Practical: rare for US persons to deliberately set up foreign trusts now (Domestic foreign trust planning is complex). But inheritances and transfers from foreign family arrangements may trigger.

Strategy:

Avoid creating foreign trusts when possible. US-domiciled alternatives often available.

If transfer required: minimize gain recognition; coordinate with §684 rules; consider partial transfers.

Existing foreign trusts: ensure proper reporting.

Part II: US Owners of Foreign Trusts

Under §671-679 grantor trust rules: certain trusts are treated as owned by US grantor for income tax purposes.

If US person is treated as owner of foreign trust:

Annual Form 3520-A reporting required (or Form 3520 Part II if 3520-A not filed).

Foreign trust grantor trust status:

Generally if US person funded the trust and retains certain powers, they’re treated as owner.

§679 specifically targets US grantors: if US person transfers property to foreign trust with US beneficiaries, US grantor treated as owner.

Form 3520-A reports:

Trust’s annual income, deductions, and credits.

Trust’s beneficiaries and distributions.

Trust’s assets and balance sheet.

US grantor reports trust’s income on personal tax return (Form 1040).

Trust may file its own foreign tax return depending on jurisdiction.

Form 3520 Part II: alternative reporting if 3520-A wasn’t filed by trustee. US grantor must report trust info.

Penalties: greater of $10K or 5% of trust assets per year for failure.

For $5M trust: $250K potential penalty per missed year.

Part III: Distributions from Foreign Trusts

When US person receives distribution from foreign trust, Form 3520 Part III reports.

Required reporting threshold: any distribution from a foreign trust requires reporting (no minimum). Different from foreign gift threshold.

What’s reported:

– Date of distribution – Amount distributed – Form of distribution (cash, property) – Trust information

Tax consequences of foreign trust distributions:

Two main types:

1. Distribution from foreign grantor trust where US person is beneficiary (not grantor): generally taxable as ordinary income.

2. Distribution from foreign non-grantor trust: complex tax treatment.

Foreign non-grantor trust distributions:

Current trust income distributed to beneficiary: taxable to beneficiary at beneficiary’s tax rates.

Distribution of accumulated income (from prior years): subject to ‘throwback’ rules under §665-667.

Throwback rules:

Distribution of accumulated income taxed in YEAR DISTRIBUTED but at the BENEFICIARY’s prior year tax rates as if the income had been distributed when earned.

Plus interest charge under §668 for years between accumulation and distribution.

Effect: similar to PFIC §1291 default treatment. Punitive for long-accumulated foreign trust income.

Practical: foreign trust distributions of long-accumulated income face ordinary tax + interest charges.

Strategy: avoid letting income accumulate in foreign non-grantor trust. Distribute regularly to beneficiaries.

Reporting complexity:

Beneficiary must obtain detailed trust accounting information (DNI calculation, income history) from foreign trustee. Often difficult; trustees may not provide.

If beneficiary doesn’t have information: ‘default method’ under Form 3520 — treats distribution as accumulated income with throwback. Very punitive.

Part IV: Large Foreign Gifts and Bequests

IRC §6039F requires reporting of large gifts and bequests from foreign persons.

Thresholds (2024-2025):

Gifts from nonresident alien individuals or foreign estates: aggregate $100,000+ per year.

Gifts from foreign corporations or foreign partnerships: aggregate $19,570+ per year (adjusted for inflation).

Reported on Form 3520 Part IV.

What’s reported:

– Donor identification (foreign person) – Description of gift – Value of gift – Date received

Tax consequences:

Gifts from foreign persons are GENERALLY NOT TAXABLE to recipient (US person doesn’t pay tax on receiving gifts).

BUT: failure to report triggers severe penalty.

Penalty for failure: 5% of gift value per month after due date, up to 25% maximum.

Example: $500K foreign gift unreported.

Penalty after 1 month late: 5% × $500K = $25K After 5+ months: 25% × $500K = $125K maximum penalty The penalty alone is substantial.

Foreign inheritance scenarios:

1. US person inherits property from foreign relative. Inheritance over $100K threshold: Form 3520 required.

2. US person receives wire transfer from foreign parents over $100K: Form 3520 required.

3. US person receives multiple gifts from same foreign donor totaling $100K+: aggregate reporting required.

Common error: not realizing reporting required for inheritance/gifts. The receipt is non-taxable, but reporting is mandatory.

Documentation: keep wire transfer receipts, gift letters, inheritance documents.

Form 3520-A: Annual Foreign Trust Information

Form 3520-A is filed BY the foreign trust (or by US owner if trust doesn’t file).

Information required:

– Trust identification – Trustee information – Trust accounting (balance sheet, income statement) – Beneficiary information – Distribution details

Foreign trustee may or may not be willing to provide. Some refuse on privacy or jurisdictional grounds.

If trustee won’t file: US owner must file Form 3520-A on their own behalf.

Information difficulties:

Foreign trust accounting may not match US tax requirements. Conversion required.

Foreign trustee may charge fees for providing information. Some don’t comply with US requests at all.

US person ultimately responsible for filing regardless of trustee cooperation.

Due date: March 15. Extension to September 15 via Form 7004.

Penalties:

Greater of $10K or 5% of trust assets per year.

If trust has $2M of assets: $100K penalty per missed year.

Continuing failure: additional $10K/month after notice, up to maximum.

Coordination with Form 3520: same trust events trigger both forms. Form 3520-A is the trust-level return; Form 3520 is the beneficiary-level return.

Common Foreign Trust Scenarios

Scenario 1: US grad student receives $150K wire from parents in Italy for living expenses.

This is a foreign gift over $100K threshold. Form 3520 Part IV required.

Reporting: file Form 3520 with current year tax return.

Tax: $0 (gifts from foreign persons not taxable to recipient).

Penalty risk if not filed: up to 25% × $150K = $37,500.

Worth filing on time. Simple form (just Part IV) for this scenario.

Scenario 2: US person inherits $500K from UK grandparent.

If from a UK estate (foreign estate): Form 3520 Part IV for foreign bequest over $100K.

If from a UK trust: Form 3520 Part III for trust distribution.

Different parts depending on form of inheritance.

Tax treatment varies by structure. Get specialized advice.

Scenario 3: US child is beneficiary of foreign trust set up by foreign grandparents.

If parents/grandparents established trust as foreign grantor trust: US child as beneficiary receives distributions; reports on Form 3520 Part III.

If non-grantor trust: complex throwback rules may apply.

Critical: get detailed trust accounting from trustee to apply correct treatment.

Scenario 4: US person establishes Cayman trust for asset protection.

Foreign trust with US grantor: §679 applies; US grantor treated as owner.

Annual Form 3520-A (or 3520 Part II) required.

All trust income reported on US grantor’s personal return.

FBAR and Form 8938 may also apply to trust accounts.

Scenario 5: US person receives in-kind distribution of foreign real estate from foreign trust.

Form 3520 Part III for distribution.

Tax treatment: §665-667 throwback rules may apply.

Real estate received: takes basis equal to trust’s basis.

Future sale of real estate: gain calculated on trust basis.

Penalty Regime

Form 3520 / 3520-A penalties are among the steepest in international tax compliance:

Foreign trust transfers (Part I): greater of $10K or 35% of FMV of transfer.

Foreign trust ownership (Part II / 3520-A): greater of $10K or 5% of trust assets per year.

Foreign trust distributions (Part III): greater of $10K or 35% of distribution.

Foreign gifts/bequests (Part IV): 5% per month, max 25% of gift value.

Continuing failure: additional $10K per month after IRS notice (up to maximum).

Reasonable cause defense:

Penalties can be waived for reasonable cause under §6677(d).

Factors:

– Reliance on tax professional advice – Honest mistake or misunderstanding – Bookkeeping problems – Health issues affecting filing – Foreign trustee non-cooperation despite reasonable efforts

Penalty abatement:

Successful reasonable cause arguments have eliminated $50K-$500K of Form 3520 penalties.

Documentation essential: contemporaneous records, communications with trustee, professional advice received.

First-time abatement: NOT generally available for Form 3520 penalties under current IRS policy.

International information return penalty review (2023+):

IRS announced improved focus on international information return compliance. Penalty assessments increased.

Streamlined Disclosure procedures: provide path to compliance with reduced penalties for non-willful violations.

Voluntary Disclosure Practice: for willful violations.

Quiet disclosure: file delinquent forms without entering program. Risk: IRS may treat as willful if discovered.

Coming into Compliance

If you’ve missed Form 3520 filings:

Step 1: Assess scope.

Which years have unreported foreign trust transactions or gifts? Which forms missed?

Categories:

– Foreign gifts over $100K: how many years, what amounts? – Foreign trust distributions: how many, when, amounts? – Foreign trust ownership: years of unreported trust ownership?

Step 2: Assess willfulness.

Non-willful: didn’t know about Form 3520 requirements (most common for inheritance/gifts).

Willful: knew about requirement and deliberately didn’t file (rare).

Most cases are non-willful. Document this.

Step 3: Choose compliance path.

Streamlined Filing Procedures: for non-willful violations.

Streamlined Domestic Offshore (if US-resident): reduced penalties.

Streamlined Foreign Offshore (if non-resident): no penalties under specific conditions.

Voluntary Disclosure Practice: for willful violations.

Quiet disclosure (file delinquent without program): risky.

Step 4: File delinquent forms.

Form 3520 for each missed year.

Form 3520-A for each missed year (if applicable).

Form 1040-X (Amended Return) if income from foreign trust wasn’t reported.

Step 5: Pay any back taxes plus interest.

Form 3520 itself doesn’t generate tax. But income from foreign trust may be unreported on Form 1040.

Streamlined penalty: 5% of largest aggregate balance of all unreported foreign financial assets during look-back period.

For Form 3520 issues specifically: streamlined procedures cover.

Step 6: Maintain compliance going forward.

Annual Form 3520 filings as required.

Documentation of foreign trust transactions.

Communication with foreign trustee for required information.

Professional preparation: $2K-$10K+ per year for foreign trust reporting.

Cost vs. risk: penalty exposure can be $100K+ for substantial unreported amounts. Compliance investment is small relative to risk.

Foreign Trust vs. Other International Reporting

Foreign trust reporting interacts with other international tax reporting:

Form 8938 (FATCA): foreign financial assets including foreign trust interests. Higher thresholds.

FBAR (FinCEN 114): foreign financial accounts held in trust may trigger FBAR if accounts exceed $10K aggregate.

Form 5471: foreign corporations (different from foreign trusts).

Form 8621: PFICs (different from foreign trusts).

Form 1040 Schedule B: foreign accounts indicator question (Part III).

Coordination matters: foreign trust holding investments may require multiple forms simultaneously.

For one US beneficiary of foreign trust holding foreign mutual funds: potentially Form 3520, Form 8938, FBAR, AND Form 8621 — all annual filings.

Each form has separate penalty regime. Cumulative penalties for one foreign relationship can exceed $50K-$100K per year for non-willful violations.

Coordinated professional advice essential for international situations.

Streamlined disclosure procedures consider all international forms collectively.

Common Mistakes

Issues we see:

1. Not realizing inheritance is reportable. US person inherits $200K from foreign parent; thinks it’s tax-free (correct) so doesn’t report (incorrect — reporting required).

2. Not realizing trust distributions need reporting. Foreign family trust distributes to US beneficiary; recipient reports income (sometimes correctly) but misses Form 3520.

3. Foreign trustee non-cooperation. Trustee won’t provide information for Form 3520-A; US person doesn’t file.

4. Streamlined procedures not used. Voluntary correction reduces penalty exposure; not using available program.

5. Aggregating gifts incorrectly. Multiple gifts from same foreign person to same US recipient must be aggregated. Easy to miss.

6. Trust-to-corporation-to-trust distribution chains. Complex foreign structures may have nested trusts/corporations. Reporting cascades.

7. Tax preparer unaware. Many domestic CPAs don’t routinely handle Form 3520. Specialized international tax practitioners needed.

Professional resources:

– International tax attorney (especially for streamlined procedures and large amounts) – CPA with international experience – Specialized expat/inbound tax preparation firms Cost: Form 3520 preparation $500-$3,000+ per form. Streamlined disclosure: $5K-$25K including all years and forms.

For substantial foreign assets or recurring foreign trust interactions: ongoing relationship with specialized professional essential.
