How to Fill Out IRS Form 3520? (w/ Examples) + FAQs

According to a 2023 IRS Taxpayer Advocate report, the IRS assessed over $844 million in penalties from 2018–2021 for unreported foreign trusts and gifts – with an average penalty of $226,000. In plain terms, failing to file Form 3520 can cost you dearly. So, how do you fill out Form 3520 correctly and avoid those massive fines?

Filling out IRS Form 3520, Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts, involves gathering information on any foreign trusts you create/own, distributions you receive, or large gifts from abroad, and reporting these details to the IRS.

You’ll need to identify which parts of Form 3520 apply to you, complete each relevant section (Parts I through IV) with accurate information (names, dates, values, etc.), attach any required statements, sign the form, and submit it by the deadline (typically April 15, with extensions available). It’s an informational return – no tax is calculated on the form itself – but it’s mandatory if you meet the criteria. Below, we’ll walk you through everything step by step.

What Is IRS Form 3520 and Why Does It Matter?

IRS Form 3520 is a specialized information-reporting form that U.S. taxpayers must file to disclose certain international transactions. In simple terms, Form 3520 reports:

• Foreign Trust Involvement: If you created a foreign trust, transferred money or assets to one, or if you own a foreign trust (as a grantor) under U.S. tax rules, or if you received distributions or loans from a foreign trust.
• Large Foreign Gifts or Inheritances: If you received large gifts or bequests from foreign persons (including foreign relatives, estates, corporations, or partnerships) that exceed specific dollar thresholds.

This form matters because the U.S. government wants transparency into significant offshore assets and transfers. Why? Because foreign trusts and large gifts from abroad can potentially be used to hide taxable income or evade taxes. By requiring disclosure, the IRS can ensure you’re not secretly dodging U.S. tax through foreign entities or funds. Even though most foreign gifts and trust distributions aren’t themselves subject to income tax (for example, a genuine gift is tax-free to the recipient), the IRS uses Form 3520 to keep a record and verify that no tax laws are being skirted.

Failure to file Form 3520 when required can lead to draconian penalties (tens of thousands, even millions, of dollars in worst cases). In fact, as mentioned, billions in penalties have been levied for not filing or filing incorrectly. This form’s importance is underscored by those hefty fines – the IRS is effectively saying “We take this seriously!”. By properly filling out Form 3520, you protect yourself from these penalties, comply with federal law, and maintain good standing. It’s essentially a safeguard: file the form, and you won’t suddenly be on the hook for enormous fines or legal troubles down the road.

In short, Form 3520 is about disclosure and compliance. It doesn’t make you pay extra tax on a gift or trust (unless there’s undisclosed income), but it ensures the IRS knows about it. The form provides answers to what money or assets moved between you and foreign trusts or persons, when it happened, who was involved, and why (gift, loan, distribution, etc.). Understanding its purpose is the first step in demystifying how to fill it out.

Who Must File Form 3520 (Federal Requirements)

Not everyone needs to file a Form 3520. It is required only if you had certain foreign trust or gift activities during the tax year. Under federal law, you must file Form 3520 if any of the following situations apply to you:

1. You had a “Reportable Event” with a Foreign Trust. This means you are the U.S. person responsible for reporting a certain event, such as:
   • Creating or Transferring Assets to a Foreign Trust: If you created a foreign trust (basically, set up a trust in another country) or transferred money or property (including cash) to a foreign trust.
   • Certain Related Transfers: If you transferred assets to a person or entity related to a foreign trust, or loaned money to a foreign trust in exchange for a note that qualifies as a “qualified obligation.”
     In these cases, you’re the “responsible party” who must report the trust creation/transfer. You’ll fill out Part I of the form.
2. You are the owner of a foreign trust (per U.S. rules). If you’re a U.S. person and, under the grantor trust rules (Internal Revenue Code §§ 671–679), you are treated as the owner of some or all of a foreign trust’s assets, you must file Form 3520.
   • In plain language, this typically means you funded a trust abroad and retain certain powers or benefits, making it a “grantor trust” to you.
   • Even if there were no transactions during the year (no money added or removed), if you’re considered the owner of a foreign trust, you still must file annually. You’ll focus on Part II of the form (and ensure the trust files a Form 3520-A or you attach a substitute).
3. You received money or assets from a foreign trust. If during the year you (or your U.S. estate) received a distribution from a foreign trust, you must report it on Form 3520. This includes:
   • Direct distributions (cash or property that the trust gave you).
   • Indirect or deemed distributions – for example, if you or a related person received a loan from a foreign trust or even had free use of trust property (like using a trust-owned vacation home without paying fair rent). These are treated as trust benefits and must be reported as distributions.
   • Also, if a foreign trust forgave a loan you owed or paid something on your behalf, that’s a distribution to report.
     In these cases, you fill out Part III of Form 3520 detailing the distribution.
4. You received large gifts or inheritances from foreign individuals or entities. If foreign persons gifted or bequeathed money or property to you, and it exceeds certain thresholds, you must file:
   • Gifts/Bequests from Foreign Individuals or Estates: If you received more than $100,000 in total during the year from a nonresident alien individual or foreign estate (including multiple gifts from related foreign persons that together exceed $100k). This typically covers inheritances from foreign relatives or large personal gifts.
   • Gifts from Foreign Corporations or Partnerships: If you received more than a certain threshold (around $17,000, but indexed for inflation each year) in gifts from foreign corporations or foreign partnerships. The exact threshold is set by the IRS annually (known as the “section 6039F threshold amount” – roughly in the mid-five-figures). These usually indicate something that could be a distribution in disguise, so they want it reported as well.
     If you cross these limits, you must file Part IV of Form 3520 to report the foreign gifts/bequests. (Multiple smaller gifts from the same donor or related donors are aggregated – you can’t skirt the rule by splitting one big gift into pieces.)

In summary, Form 3520 is required if you did any of the above: interacted with a foreign trust (by creating, transferring, owning, receiving from, or lending to it) or received sizable foreign gifts. U.S. persons who can be required to file include U.S. citizens and residents, domestic corporations or partnerships (if they are transferors or owners of foreign trusts), and executors of estates of U.S. decedents in some cases. Basically, if you’re a U.S. taxpayer and had these foreign transactions, the IRS wants to hear about it.

Important: If none of these events happened for you in the tax year, you do not need to file Form 3520. Don’t file it “just because” – only file if required. But if you’re on the fence (e.g. “I got a $90k gift, do I need to file?” – answer: not if it truly was only $90k from a foreign individual, since under $100k threshold), it’s good to double-check the exact rules or consult a professional. When in doubt, disclose – filing won’t hurt if you weren’t required (it’s just extra paperwork), but not filing when required is a big problem.

State Nuances: Foreign Trusts and Gifts in All States

Form 3520 is a federal requirement, and it’s governed by federal tax law. Individual U.S. states generally do not have their own equivalent of Form 3520. So, you typically do not need to file a separate state form to report foreign trusts or foreign gifts. Whether you live in California, New York, Texas, Florida or any other state, the rules for Form 3520 filing are the same at the federal level.

That said, there are a few state-related considerations to keep in mind:

• State Income Tax on Trust Distributions: While a gift is not taxable income federally or at the state level, a distribution from a foreign trust might include income (for example, the trust’s interest or dividend earnings). Any portion of a trust distribution that is considered income to you for federal tax purposes (e.g. accumulated interest) will generally also be taxable on your state income tax return. In other words, if you report foreign trust distribution income on your federal Form 1040, you’ll report it on your state return as well. The state will tax that income just like any other income, because states mostly follow federal definitions of taxable income. So, ensure you don’t ignore the state tax implications of any taxable portion of a trust distribution.
• No State Gift Reporting: States do not tax gifts received, and they don’t require you to report gifts from foreign persons separately. (Notably, only one state – Connecticut – has its own gift tax for donors, but that applies to gifts made by Connecticut residents, not gifts received, and a foreign donor wouldn’t be subject to it anyway.) So if your only Form 3520 trigger is receiving a foreign gift, no state filing is needed for the gift itself.
• Community Property States: If you live in a community property state (like California, Texas, Arizona, etc.), a question might arise: if one spouse receives a foreign gift, does it become joint property? Generally, assets received by gift or inheritance are treated as separate property of the spouse who received them, even in community property states. So if you personally get a $200K gift from your overseas parents, it’s usually your separate property, not automatically half your spouse’s. Thus, only you would file Form 3520 for that gift (not your spouse, unless it was explicitly given to both of you). On the form, there is an option to file jointly if both spouses have reportable transactions with the same trust, but a gift to one spouse wouldn’t require a joint filing. This nuance rarely affects the form, but it’s good to note for marital property considerations.
• State Foreign Asset Disclosure: A few states have begun asking about international assets or accounts in their own tax forms (for instance, California’s tax return asks if you have overseas assets above certain amounts, mirroring federal FATCA thresholds). However, these are just yes/no questions to piggyback on federal compliance. They do not replace or duplicate Form 3520. Always handle Form 3520 at the federal level, and simply answer any state tax return questions truthfully about whether you filed the required federal forms.

In summary, all states defer to the federal requirements when it comes to foreign trust and gift reporting. No matter what state you reside in, if you meet the federal criteria for Form 3520, you file it with the IRS. You won’t file a Form 3520 with your state. Just remember that any actual taxable income from a foreign trust still gets reported on your state return like normal income. If you’re unsure, consider consulting a tax professional familiar with both federal and state rules, but rest assured that Form 3520 itself is purely an IRS matter.

When Is Form 3520 Due and Where Do I File It?

Timing is critical with Form 3520, because missing the deadline can automatically trigger penalties. Here’s what you need to know about when and where to file:

• Due Date: Form 3520 is due on the same day as your income tax return would be, not including extensions. For individual calendar-year taxpayers, that’s typically April 15 of the following year. However, if you file for an automatic extension for your Form 1040 (by filing Form 4868, for example), your Form 3520 deadline is also extended to the extended due date (October 15 for most individuals). You don’t need a separate extension form for 3520 – the IRS grants it automatically if you have a valid tax return extension.
  • Exception: If you are a U.S. citizen or resident living abroad on the normal due date, you generally get an automatic 2-month extension (to June 15) to file Form 3520 (similar to the automatic extension for your 1040 in that scenario). For instance, if you’re an expat residing in London or serving in the military overseas, the due date would be June 15, not April 15. (Be sure to attach a statement to your form explaining that you qualify for this later deadline due to foreign residency or military service abroad.)
  • In short, April 15 is the standard due date; Oct 15 if extended; June 15 if abroad (and then Oct 15 if you also formally extend). Always double-check each year’s IRS guidance if in doubt, but those are the general rules. And if the due date falls on a weekend or holiday, it rolls to the next business day.
• Where to File: Unlike your regular tax return, Form 3520 is NOT attached to your 1040. It is mailed separately to the IRS. As of current IRS instructions, the completed Form 3520 (with all attachments) should be mailed to the IRS Service Center in Ogden, Utah. The address (for U.S. mail) is:
  Internal Revenue Service Center
  P.O. Box 409101
  Ogden, UT 84409 If you use a private courier (FedEx, UPS, etc.) that won’t deliver to a P.O. box, the IRS instructions provide a street address (often a different Ogden address) – check the latest instructions for that if needed. For most, mailing via USPS Certified Mail to the P.O. box is a good approach (you get proof of mailing and delivery). Currently, electronic filing of Form 3520 is not widely available as an option (unlike many standard tax forms). It’s a paper filing in most cases. Always include all required attachments (for example, any Foreign Grantor Trust statements, or an explanatory statement if you’re filing late with reasonable cause, etc.) when you mail it. The IRS needs those attachments for the form to be considered complete.
• Signature: Don’t forget to sign and date the form before mailing. If you’re filing as an individual, you sign it yourself. If it’s on behalf of a partnership, corporation, or trust, an authorized officer or fiduciary would sign. (On a joint individual 3520 for spouses, typically both should sign.) There’s also a paid preparer section at the bottom if you used a CPA or attorney to prepare it – they will sign there and include their info.
• Keep a Copy: Always keep a copy of the filled Form 3520 and any attachments for your own records. This is important in case the IRS ever questions your compliance or if you need to reference what was reported in future years.

Filing on time is crucial. If you miss the deadline (including an extended deadline), the penalties can kick in automatically. In fact, for a period the IRS was sending automatic penalty letters for late Forms 3520, though due to pushback (and as of 2023) they announced they would stop automatically assessing the penalty without human review. Still, the law allows them to penalize late or missing forms, so don’t rely on leniency – get it in on time or as soon as possible if late.

Bottom line: Mark your calendar for Form 3520’s due date just as you would for your tax return, and mail it to the IRS in Ogden, UT. Timely filing to the correct address keeps you in the clear.

Filling Out Form 3520: Step-by-Step Instructions

Now let’s get into the nuts and bolts of actually filling out Form 3520. The form can look intimidating at first glance – it’s multiple pages long and divided into four main parts plus schedules. But remember, you only complete the parts that apply to your situation. We’ll break it down part by part, with a step-by-step approach:

Preparation: Gather Information and Documents

Before you put pen to paper (or cursor to PDF), do a bit of homework:

• Download the latest Form 3520 and Instructions: You can get these from the IRS website. Make sure you have the current version (Form 3520 is now a continuous-use form updated as needed – as of writing, the December 2023 revision is current). Having the official instructions on hand is helpful for detailed line-by-line questions.
• Identify what parts you need to fill:
  • If you only received foreign gifts above the threshold and no trust involvement, you’ll be filling out Part IV (and the basic info at the top).
  • If you had foreign trust transactions or ownership, you’ll have Parts I, II, or III to fill out depending on the scenario (possibly more than one part if multiple roles).
  • If in doubt, it’s okay to fill out more rather than less. The form’s structure will guide you: e.g. Part III asks if you got distributions; if not, you can skip it.
• Gather key details:
  • For foreign gifts: You’ll need the amount of each gift and the identity of the donor (name and address, and relationship to you). If multiple gifts from one person, you’ll aggregate them.
  • For foreign trust transfers/creation: Get the trust’s name, address, and identifying number (if it has a U.S. Employer ID Number, EIN, or foreign tax ID). Know the date and amount of each transfer you made. If you got a note or promise in return (obligation), have details on that.
  • For trust ownership (grantor): You’ll want the Foreign Trust’s financial statements or the Foreign Grantor Trust Owner Statement from the trustee (part of Form 3520-A). This shows the trust’s income, expenses, etc., that you as owner have to report. Also the trust’s identifying info as above.
  • For trust distributions: List out each distribution or loan: the date, amount, type (cash, property, loan, etc.). Ideally, obtain a Foreign Trust Beneficiary Statement from the trustee detailing the distribution breakdown (this statement will tell you if it was income, corpus, etc., which matters for taxes).
  • Your own info: Have your name, address, taxpayer ID (SSN or EIN) ready. If filing jointly for you and spouse (and both had reportable events with the same trust), note that as well.

Having these details at hand will make filling the form much smoother.

Now, let’s go part by part:

Page 1 – Basic Information

Start with the top of Form 3520 (Page 1):

• Name and Identification: Fill in your name as the “Name of U.S. person” filing the return. If this is for a trust or estate or corporation, put that entity’s name. For individuals, also include your Social Security Number or taxpayer ID on the line provided. If you are filing jointly with a spouse (and both of you need to report the same foreign trust or gifts), enter both names and SSNs (and you’d check the joint filing box as described next).
• Address: Provide your mailing address (the address the IRS should use if they need to contact you about this form). If you’re abroad, you can enter a foreign address here.
• Initial Questions/Boxes (Line 1 items): There are checkboxes (A through H on the 2023 form) asking for some high-level info:
  • Line 1a (Check if joint filing): If you and your spouse are filing one combined Form 3520 (because, say, you both are beneficiaries of the same foreign trust), check this box. Most people will leave it blank, since typically one person files for their own situation. Only use it if truly applicable.
  • Line 1b asks your identifying number (SSN or EIN) which we already covered by filling it in.
  • Line 1c if you’re an individual, and you did file a joint income tax return with your spouse, enter your spouse’s name here (this is different from a joint 3520; this just ties to your 1040 status).
  • Line 1d would be spouse’s identifying number if applicable.
  • There’s a line to check if you’re an executor filing for a deceased person’s estate (Line 1i in recent forms). For example, if you are the executor of a U.S. person’s estate and that person died but had a foreign trust distribution in their final year, you’d be filing Form 3520 on behalf of the estate – check “Executor” if so.
  • Another checkbox asks if this is an amended return (filing a correction to a previously filed Form 3520). Check that if you’re sending in a corrected form.
• Lines 2 and 3 – Responsible party/Owner info: These lines capture if you’re reporting a trust transfer or ownership:
  • If you’re reporting a transfer to a foreign trust (Part I), Line 2 asks for the identifying info of the trust (name, EIN if any).
  • If you’re reporting as an owner of a foreign trust (Part II), Line 3 asks for the trust’s identifying info. Often, the trust won’t have a U.S. EIN unless one was obtained; if none, you might write “Foreign Trust, no EIN”.
• Lines 4, 5, etc.: These initial lines basically set up what’s to follow. They’ll ask:
  • Was the foreign trust created by a will or death (a testamentary trust)?
  • Was the foreign trust previously a domestic trust that became foreign?
  • Are you a U.S. owner of the trust, or a trustee of it, etc. (It gets a bit technical – refer to instructions. Generally, if you are filling Part II, you are a U.S. owner; if you also happen to be the trustee and a U.S. person, you might answer those accordingly.)
  • If you’re just reporting foreign gifts (Part IV only) and have no trust involvement, many of these lines won’t apply – you might leave them blank or answer “No” as appropriate.

Fill out the basic info section as it pertains to you. Once the top section is done, you’ll proceed to the parts relevant to your situation:

Part I – Transfers by U.S. Persons to a Foreign Trust

Part I is about reporting “reportable events” when you transfer assets to a foreign trust or establish one. You ONLY fill Part I if you did one of the following during the year:

• Created a new foreign trust.
• Transferred money or property to an existing foreign trust (including through intermediaries).
• Or if you are the “responsible party” for certain trust events (like if you’re the executor of someone who died and their trust became foreign at death – a bit niche).

If none of that happened, skip to Part II or wherever applicable. But let’s assume you did have a transfer:

Lines 5 & 6: These ask for basic details of the trust transfer:

• Line 5a: Name of the trust, and identifying number (if any).
• 5b: Date of the transfer.
• 5c: The fair market value of the property or cash you transferred.

If you made multiple transfers to various trusts, you would complete a separate Part I section for each (meaning you might have to attach a statement or additional pages, since the form has space for one trust’s info in the main form). The form’s format might allow listing multiple transfers to the same trust together.

Line 7 & 8: These deal with transfers where you got something in return:

• For example, if you transferred property to the foreign trust in exchange for an “obligation” (a note, promise to pay, or other debt instrument from the trust or a related person). The IRS wants to know if that obligation is a qualified obligation (a term defined by strict IRS rules, basically a legitimate, arm’s-length loan with a term not exceeding 5 years and proper interest, etc.).
• Line 7a asks if you received an obligation from the trust in exchange for the property you transferred. If yes, you must answer whether it’s a qualified obligation on line 7b. A “Yes” on 7b means it meets all the criteria (interest at federal rates, not longer than 5 years, etc.). If it’s not qualified, that could have other tax implications (like the transfer might be treated as a gift or other event).

Line 8: If you hold any outstanding qualified obligations from prior transfers to the trust (from earlier years), you report that here (the amount and the date of original obligation). This is keeping track of ongoing loans between you and the trust.

Line 9: If you transferred property that had a gain (like stock that went up in value) and you didn’t recognize the gain at the time (perhaps due to a non-recognition provision), you have to provide info here. The IRS doesn’t want people avoiding capital gains tax by shuffling appreciated assets into foreign trusts without reporting; they may force recognition of gain in some cases.

Schedules A, B, C (Part I): Depending on what you answered above, you may need to fill a schedule:

• Schedule A – Obligations of a Related Trust: If you indicated any trust obligations, this is where you detail them.
• Schedule B – Gratuitous Transfers: This is where you describe the property you transferred, especially gratuitous transfers (meaning no full consideration in return). You list property description, date, fair market value, and if applicable, the U.S. adjusted basis. Essentially, if you gifted something to the trust, list it here.
• Schedule C – Qualified Obligations Outstanding: If you had any qualified obligations (loans) still outstanding at year-end, you detail them (amount, date, due date, etc.).

For many individual filers, Part I might be straightforward: e.g. “I wired $300,000 to the XYZ Family Trust in Country X on June 1; it was a gift to the trust (gratuitous transfer).” You’d fill lines 5a-c, say “no” to receiving any obligation in return on line 7, and then in Schedule B, describe “Cash transfer of $300,000 on June 1 to XYZ Trust, fair market value $300k, basis $300k (since it’s cash).”

Be thorough and accurate: list all reportable transfers. If you transferred multiple assets (say stock shares and cash), list each. The IRS later can match this info with what the foreign trust reports on its own Form 3520-A.

Part II – Annual Information of Foreign Trust Ownership (U.S. Owner)

Part II is filled out by anyone who is treated as the U.S. owner of a foreign trust (in whole or in part). This typically means it’s a grantor trust to you – you put assets into a trust abroad and retain certain powers or benefits, so under U.S. tax law you still “own” those assets for tax purposes.

If you have to file Part II, it’s usually a yearly requirement until the trust terminates or you cease to be an owner. Even if you had no transfers or distributions in a given year, as an owner you must report the trust’s income information.

Line 10-13 (Trust Info): You’ll provide:

• The foreign trust’s identifying information: name, address, country where it’s organized.
• The trust’s U.S. Employer ID Number (EIN) if it has one (if not, and if you as owner are filing a substitute Form 3520-A, you might have applied for an EIN for the trust).
• The date the trust was created.
• The owner percentage: If you’re not the 100% owner, what portion do you own? For example, if you and a sibling (both U.S. persons) are grantors who each contributed assets, you might each be considered owners of a portion. Often though, one grantor = 100% owner.

Income and Asset Information: As a trust owner, you must ensure that Form 3520-A (Annual Information Return of Foreign Trust With a U.S. Owner) is filed. Form 3520-A is a separate form (filed by March 15, usually by the foreign trustee, or by you as a substitute if the trustee doesn’t file). It contains the trust’s financial statements: a balance sheet and income statement, plus statements to the owners and beneficiaries.

• If the foreign trustee actually filed Form 3520-A and sent you a copy of the “Foreign Grantor Trust Owner Statement,” you will attach that statement to your Form 3520. Part II of Form 3520 will ask if Form 3520-A was filed and if the annual statements were provided to you. You should answer Yes if you received those documents. If No (the foreign trust failed to file 3520-A), you need to attach a substitute Form 3520-A (basically, fill out the 3520-A for them and include it with your submission). This is critical: by doing so, you avoid the separate penalty for the trust not filing 3520-A (which would hit you at 5% of trust assets per year).
• Part II will prompt you to report summary info: For example, the amount of trust income attributable to you. Since as an owner, you must report the trust’s income on your own 1040, they want to see that on Form 3520 too. You’ll list any interest, dividends, capital gains, etc., that the trust earned (and which you, as owner, are picking up on your tax return). Essentially, Part II ties out the trust’s income to your personal tax reporting.
• You may also report any distributions you (as owner) took from the trust (but distributions to an owner aren’t taxable separately because you already are taxed on the income – still, it might be informationally required to note).
• There’s a question about U.S. agent for the trust: If a U.S. agent was appointed (to provide IRS with records if asked), you should list them. If no U.S. agent, the IRS has authority to determine income in a worse way for you (so typically, it’s recommended to have an agent or provide the info voluntarily).

In summary, Part II is mostly compliance-checking: Did you report all the trust’s income? Did the trust do its part (file 3520-A)? Provide the identification and basic financial figures to demonstrate transparency.

As an example: Say you are a U.S. person who established the “ABC Foreign Trust” in 2022 in the Cayman Islands, funding it with $1 million. You remain the grantor with powers, so it’s a grantor trust to you. In 2024, the trust’s bank/brokerage accounts earned $50,000 of interest and dividends, and you know this because either the trustee gave you an accounting or you have access. You would file Form 3520 for 2024:

• Part II: List ABC Trust, created on X date, located in Cayman, no EIN (or EIN if you got one). Indicate you’re 100% owner.
• You’d ensure a Form 3520-A gets filed (or do it yourself). Then in Part II, you might state $50,000 of income is attributable to you (which you also report on your Form 1040). Attach the owner statement from 3520-A showing that $50k.
• If you took no distribution (you left all income in the trust), that’s fine; you still are taxed on it and report it here.

Part III – Distributions to a U.S. Person from a Foreign Trust

Part III is for reporting any distribution (or deemed distribution) you, as a U.S. person, received from a foreign trust during the year. If you answered in Part I or II that you got a distribution or loan, you’ll need to fill Part III. If you’re solely reporting foreign gifts and have nothing to do with trusts, skip Part III.

What counts as a distribution?

• Any cash or property the foreign trust gave you.
• Any loan from the trust (yes, even if you have to pay it back, the IRS treats a loan as a benefit unless it meets strict criteria).
• Use of trust property (like living in a trust-owned house, driving a trust-owned car, artwork on your wall from the trust) without fair market compensation.
• Basically any benefit you got from the trust.

Line 24 & 25: These lines usually ask for the gross distribution received and breakdown:

• You list the amounts distributed, and possibly the date of each distribution.
• There’s often a column for FMV (Fair Market Value) of property if property was distributed (e.g., trust gave you stock or a car, what’s its value).
• If it was a loan or use of property, you might list it as well (with an equivalent value of the benefit).

Beneficiary Statement: If the trust provided you with a Foreign Trust Beneficiary Statement (which is part of Form 3520-A, showing the trust’s current year income, accumulated income, etc.), then you have a very important advantage:

• With a beneficiary statement, you can determine how much of the distribution is from current-year trust income vs prior accumulated income vs corpus (original trust principal).
• Why does that matter? Because current-year income distributed to you is taxed in your hands as whatever it is (ordinary income, capital gain, etc.), but accumulated income from past years (so-called Accumulation Distribution) can trigger the throwback tax and an interest charge (the IRS basically taxes you as if that income earned in prior years had been distributed then, and charges interest for the “late” distribution).
• The Beneficiary Statement allows you to fill Schedule B (Actual Calculation) of trust distributions to figure these amounts. Without it, you’re stuck with Schedule A (Default Calculation) which assumes the worst (that distributions are from accumulated income first) – often leading to a higher tax and interest charge.

So, if you have a beneficiary statement from the trust, you’ll attach it and use those numbers:

• You’ll identify the ordinary income portion, capital gains portion, etc., of the distribution.
• You’ll identify how much is just distribution of corpus (which is not taxed to you, since that’s just the original capital or already-taxed money).
• And how much, if any, is an accumulation distribution.

Schedule A vs B: The form provides two methods to calculate any accumulation distribution:

• Schedule A (Default) – use if no beneficiary statement. It forces you to treat distributions over a certain threshold as accumulated and apply some formulas (often unfavorable).
• Schedule B (Actual) – use if you have the data on trust income. You can pinpoint exactly prior undistributed income.
• There’s also a Schedule C for calculating the interest charge on any accumulation distribution.

If you have no accumulation (e.g., the trust only distributed current-year income or corpus), you might not need to do the throwback calculation.

Line 30: Part III also asks if any loans of cash or property were outstanding at year-end that you (or a related person) received from the trust. If yes, you likely had to treat them as distributions anyway, but the IRS tracks ongoing loans here.

Example: Suppose in 2024 you received two distributions from a foreign trust: one $20,000 cash in June, and one in-kind asset (say stocks worth $10,000) in December. The trust gives you a beneficiary statement showing $15,000 of 2024 income was distributed and the rest $15,000 was actually from trust corpus. On Form 3520 Part III, you list $30,000 total distribution. You’d use the info to show $15k was income (taxable, and you’ll report it on your 1040 as such – interest/dividends/whatever the character is), $15k corpus (not taxed). Since all distributed income was current-year, there’s no accumulation distribution and no interest charge. You attach the statement as proof. If you didn’t have that statement, the IRS might assume worst-case that $30k was accumulated from prior years, potentially leading to a punitive tax and interest – which is why getting proper documentation is so important.

Loans as distributions: If, say, the trust lent you $50,000 in 2024 interest-free and you didn’t pay it back by the end of 2024, that is treated like a distribution of $50,000. You’d report it here. (If you later repay, it doesn’t undo the fact it was a distribution for tax purposes, unless it was structured as a qualified obligation to start with.)

When filling Part III, be complete. For each distribution, provide description, amount, and date. If property, describe the property and its value. If you used a house, you might need to state “use of property (villa in X country) for Y days, valued at $Z fair rental value.”

This section ensures that the IRS knows you received something from the trust and can verify you handled any taxes correctly. It’s a complex area – often involving calculating a bunch of numbers – so if you had significant distributions, it may be wise to get professional help to prepare the throwback tax worksheets. But in the form, you at least disclose the amounts and attach the supporting statements.

Part IV – Reporting Large Foreign Gifts and Bequests

Part IV is distinct from the prior parts: it deals with gifts or bequests from foreign persons (individuals, estates, corporations, or partnerships). If you received money or property from foreign sources that exceed the thresholds we discussed ($100k from foreign individuals/estates, or the smaller threshold for foreign entities), this part is for you. If not, and your only involvement was with trusts, you might skip Part IV.

Line 54: This typically asks: “Did you receive more than $100,000 from foreign individuals or estates?” If yes, you check the box and you must provide details of those gifts. If no, and no other reporting in Part IV, you might skip the rest of Part IV.

Line 55: This asks about “Did you receive gifts from foreign corporations or partnerships over the threshold (6039F amount)?” If yes, likewise you’ll be detailing those.

Line 56 (and beyond): This is where you list each gift or bequest that triggers the reporting:

• You’ll list the identity of the donor (name of the individual, or name of the estate, or name of the foreign entity).
• The date and amount of the gift or bequest.
• The character of the gift (cash, wire transfer, property, etc.). For property, use fair market value on the date you received it.
• The country of the donor (since the form often asks for the country of residence or incorporation of the foreign donor).

If you received multiple gifts from related donors, it’s often required to aggregate them. For example, if you got $70k from your foreign father and $50k from your foreign mother in the same year, those are related donors (spouses) and together that’s $120k – above $100k, so yes, you must file and report both gifts (even though individually each was under $100k).

If you got $10k from a foreign friend and $10k from a completely unrelated foreign colleague, those don’t aggregate since the donors are unrelated and each is below the $100k threshold – no reporting needed in that case.

For foreign corporations or partnerships, the threshold (let’s approximate it at $17,000 for example’s sake, though it adjusts) means if you received say $20k from a foreign company (maybe they said “here’s a gift” or more likely, it might be compensation which is another story – but if truly a gift), you must report that because it exceeds the small threshold. The IRS is wary that what is called a “gift” from a foreign corporation could really be something else (like undeclared income or distribution). So they want visibility.

No tax on the gift: Remember, you do not owe income tax on a true gift or inheritance. The IRS Form 3520 reporting of a large gift is for information only. The penalty for not reporting, however, can be severe (initially 5% of the gift per month of not reporting, up to 25%!). Also, the law (section 6039F) says if you don’t report the gift, the IRS can choose to treat it as taxable income until you prove otherwise. (That’s a nasty provision – basically if you fail to file, they might assume that $200k “gift” from overseas was actually some kind of income you earned, and tax you on it). So you absolutely want to report it and avoid that scenario.

Describe the gift clearly: e.g. “$150,000 wire transfer received on July 10, 2024 from Grandmother [Name], a citizen and resident of Country Y, as an inheritance from her late estate” or “201 shares of XYZ Corp (foreign corporation) stock valued at $30,000, gifted by [Name], resident of Country Z, on Dec 1, 2024.”

You don’t have to over-explain; just give enough detail to identify what it was and who gave it. You might also indicate relationship (e.g. parent, friend, uncle) although the form doesn’t explicitly require noting the relationship, it can be helpful context.

Once you’ve listed all the foreign gifts/bequests over the limit, you’re basically done with Part IV.

Final Steps: Review, Attach, and Sign

After completing the relevant Parts I–IV:

• Review everything: Double-check that names, amounts, and dates are correct. Ensure consistency – e.g., if Part I says you transferred $X to a trust, Part II of your return or the trust’s 3520-A should reflect that contribution, etc. Make sure no required field is left blank inadvertently.
• Attach required statements:
  • Foreign Grantor Trust Owner Statement (if you’re an owner filing Part II and the trust provided one).
  • Foreign Trust Beneficiary Statement (if you got one for Part III distributions).
  • Substitute Form 3520-A (if the foreign trust didn’t file its own and you need to include it).
  • Any reasonable cause explanation if you are filing late or incomplete and want to avoid penalties. This would be a separate letter or statement you attach, explaining why you missed the deadline or why certain info isn’t available, essentially pleading your case that you had reasonable cause (e.g. “The foreign trustee refused to provide the necessary information despite my requests, here’s proof…” or “I was unaware of the requirement but filed as soon as I discovered it, and I have no history of tax issues,” etc.).
  • If you are reporting gifts and you have any documentation (like a copy of a will naming you, or a letter from grandma about the gift) you generally don’t need to attach those, but keep them in case the IRS ever asks. Usually only the above statements are required as attachments.
• Sign and Date: Make sure to sign Form 3520 at the bottom (usually on page 6 of the form). If someone helped prepare it, they should complete the Paid Preparer section as well.
• Mail it by the deadline: As discussed, send it to the IRS Ogden address (or other designated address) by the due date. Consider using certified mail or a traceable courier so you have proof it was sent and delivered. Keep the mailing receipt and tracking info.

After mailing, generally you won’t hear back if everything is in order. The IRS doesn’t “process” Form 3520 in the sense of sending a refund or bill (since it’s just informational). They only typically respond if they find something missing or problematic, or if they later want to examine the transactions further. So, no news is good news.

You’ve now completed Form 3520! Pat yourself on the back for tackling one of the more complex reporting requirements in the U.S. tax world. Next, we’ll cover some pitfalls to avoid and other helpful info to ensure you stay fully compliant and out of trouble.

Common Mistakes to Avoid on Form 3520

Even well-intentioned taxpayers can slip up with Form 3520. Here are some common mistakes (🚩) and how to avoid them:

• 🚫 Assuming “No Tax = No File”: Don’t make the mistake of thinking “Since a gift or trust distribution isn’t taxable, I can ignore the form.” Form 3520 is required even though no tax is directly due on it. It’s purely informational, but mandatory. Always file if you meet the criteria – even if the transaction had no tax impact. The IRS penalties for not filing are far worse than any hassle of filing.
• 🚫 Missing the Deadline or Forgetting the Form: It’s easy to overlook Form 3520 since it’s separate from your 1040. Mark the due date (usually April 15) on your calendar. If you get an extension for your tax return, remember that Form 3520 gets extended too, but if you didn’t file a tax extension, Form 3520 is still due April 15. Don’t file late. Late filing can trigger automatic penalty letters demanding $10,000 (or far more) in penalties. If you do file late, include a “reasonable cause” letter explaining any extenuating circumstances to ask for forgiveness.
• 🚫 Incomplete or Inaccurate Information: Filling out Form 3520 can be detailed. Common errors include:
  • Not providing full names and addresses for foreign trust owners, trustees, or gift donors.
  • Misstating amounts (for example, listing a gift’s value incorrectly in USD – make sure to convert from foreign currency at the correct exchange rate on the date of gift).
  • Forgetting to attach required statements (like the Foreign Trust Beneficiary Statement or a substitute Form 3520-A). An incomplete filing is treated almost like not filing at all. Double-check that you answered all applicable questions and attached all schedules.
• 🚫 Not Aggregating Gifts or Splitting Hairs: One trap is thinking a gift is below reporting threshold when actually you must aggregate. For instance, receiving $60k from Grandpa and $50k from Grandma (foreign persons) counts as $110k from related parties – reportable because together it’s over $100k. Or if a foreign company “gifts” you $10k twice, that’s $20k total – reportable if over the annual threshold for corporate gifts. Don’t try to split gifts among family members or across dates to dodge a filing – the IRS anti-abuse rules say they still count if the donors are related or the splitting is intentional. It’s safer to report all gifts if you even come near the threshold.
• 🚫 Confusing Form 3520 with Other Forms: Taxpayers often mix up the various international reporting forms. Form 3520 is separate from:
  • FBAR (FinCEN Form 114 for foreign bank accounts)
  • FATCA Form 8938 (foreign financial assets on your 1040)
  • Form 3520-A (annual trust report)
  • Form 709 (U.S. gift tax return for donors).
    Don’t assume that just because you filed an FBAR or Form 8938 that you covered Form 3520 – you likely haven’t, since they report different things. Each form has its own purpose and threshold. Make sure you file each required form; there is some overlap in information, but no one form substitutes for another.
• 🚫 DIY Errors in Complex Situations: While many individuals can handle a straightforward foreign gift report on Form 3520, if you have a complex foreign trust with distributions or you’re the owner of a sizable trust, it gets very complicated (think throwback taxes, figuring out trust accounting income vs corpus, etc.). A common mistake is miscalculating the taxable portion of a distribution or failing to include something like the interest charge on an accumulation distribution. If you’re not 100% confident, consider getting a qualified tax professional involved. The cost of professional help is minor compared to a mistake that triggers a huge penalty or extra taxes.
• 🚫 Not Keeping Records: You file Form 3520, but then toss out the supporting documents? That’s a mistake. Always keep copies of trust deeds, gift letters, account statements showing the transfer, communications with foreign trustees, etc. If the IRS examines your form (even years later), you’ll want to have proof of what that “$200,000 gift from Uncle Juan” was (e.g., a letter or bank record) or details on the trust. Under statute, the IRS can audit international information forms long after the normal 3-year period if they weren’t filed or were incomplete – basically the clock doesn’t start until you file a complete Form 3520. So maintain your records until at least three years after filing, if not longer.

Avoiding these pitfalls comes down to being diligent, thorough, and timely. When in doubt, err on the side of reporting and disclosure. The IRS is far more forgiving of an honest complete report (even if something seems minor) than of an omitted or sloppy filing. By steering clear of these common mistakes, you’ll greatly reduce your risk of penalties and ensure your international financial dealings remain in good standing.

Form 3520 in Action: Common Filing Scenarios

To make this more concrete, let’s look at a few real-life scenarios where Form 3520 is required, and how each situation would be handled on the form:

Scenario	How to Report on Form 3520
🎁 Receiving a Large Gift from a Foreign Relative: For example, you’re a U.S. resident and in 2024 your grandmother in India gifts you $150,000.	You would file Form 3520 Part IV. On the form, you’d note you received $150,000 from [Grandmother’s Name], a foreign person, and provide her country (India) and the date. Since $150k > $100k, it’s reportable. No tax is owed on the gift, but failing to report it could lead to penalties. Make sure to include all gifts from foreign individuals that year in aggregate.
🏦 U.S. Person Owning a Foreign Trust (Grantor Trust): You created a trust in Canada for investment purposes, funding it with $500,000. You retain control over investments (grantor trust). In 2024, the trust earns $20,000 in interest income and you take no distributions.	You must file Form 3520 Parts I and II. Part I: report the transfer of $500,000 to the foreign trust (if the creation/transfer happened in 2024). Part II: report that you are the 100% owner of the trust. You’ll attach or ensure a Form 3520-A is filed by the trustee. You’ll report the $20,000 of trust income as attributable to you (and you’d also include that $20k on your Form 1040 income). Even with no distributions, the annual filing is required as long as you own the trust.
💵 Receiving a Distribution from a Foreign Trust: You’re beneficiary of a trust in the UK set up by a relative. In 2024, you received a $50,000 distribution from this foreign trust.	You’ll file Form 3520 Part III. Report the $50,000 distribution (date and amount). If the trustee provided a Beneficiary Statement, determine how much of that $50k was trust income vs trust corpus. Say $30k was income and $20k was principal – you’d be taxed on $30k (and report that on your 1040), but not on $20k. You’d attach the beneficiary statement to back this up. If no statement was given, you may have to use default calculations (potentially treating more of it as taxable). In Part III, you’d also answer whether any part of that was an uncompensated use of property or a loan, etc. Ensure you have the trust’s info listed as well (trust name, etc., likely from Part II or Part I if applicable).

These scenarios show how different situations map onto the form. Foreign gifts → Part IV; foreign trust transfers/ownership → Parts I & II; foreign trust distributions → Part III. In some cases, more than one part applies. For example, if you created a foreign trust and also received a distribution from it in the same year, you’d fill out Part I (for the transfer), Part II (as owner), and Part III (for the distribution). Or if you got a foreign gift and also a foreign trust distribution, you’d fill the respective parts accordingly.

By walking through scenarios, you can identify which bucket your own situation falls into. Always tailor your Form 3520 filing to your specific facts. The form is flexible – it has sections for all these use cases. Your job is to fill the ones that matter and not worry about the ones that don’t.

DIY vs Professional: Pros and Cons of Filing Form 3520

Filling out a Form 3520 can range from straightforward to mind-numbingly complex. Should you tackle it yourself or hire a professional tax expert? Consider these pros and cons:

Pros	Cons
Doing It Yourself (DIY) – Saves money on professional fees. – You gain a firsthand understanding of your international financial reporting. – Full control over the process and information.	DIY Filing – Risk of errors: The form is complex; a mistake or omission can lead to huge penalties that far outweigh any savings. – Time-consuming to learn complicated IRS rules and definitions. – No expert to double-check; you might miss subtle requirements or opportunities for penalty relief.
Using a Tax Professional – Expertise ensures the form is filled out correctly and completely, reducing risk of penalty. – A professional stays updated on latest IRS rules (e.g., changes in thresholds, procedures) so nothing is overlooked. – Can help draft reasonable cause letters or navigate tricky trust calculations (throwback tax, etc.). – Peace of mind: you know an expert has handled it, and they can represent you if the IRS has questions.	Professional Help – Cost: You’ll pay fees for the service, which can be significant if the situation is complex. – You must share detailed financial information with the preparer (privacy considerations). – Finding a qualified expert: not all CPAs or attorneys are familiar with foreign trust reporting. You may need a specialist, which might mean extra effort to locate the right person.

As you can see, simple cases (like a single large gift from grandma) can often be handled on your own, especially if you’re comfortable reading IRS instructions and are detail-oriented. Complex cases (foreign trusts with earnings, multiple distributions, etc.) lean towards needing professional help due to the high stakes and complicated tax calculations involved.

One strategy some use is a hybrid: Prepare a draft of Form 3520 yourself, then pay a professional just to review it and catch any errors. This can save cost but still give some peace of mind.

Ultimately, weigh the dollar cost versus the potential risk. A mistake on Form 3520 could theoretically cost tens of thousands in penalties. If hiring a professional for a few hundred (or couple thousand for very complex trusts) saves you from that, it’s worth it. On the other hand, if you’re confident and the form is straightforward, you can certainly DIY – just triple-check your work.

Penalties and Legal Consequences for Not Filing Form 3520

The IRS enforces Form 3520 filing strictly, and the penalties for non-compliance are famously severe. It’s not just idle threats – there are cases of multi-million dollar penalties for individuals who failed to report sizable foreign trusts. Here’s what you need to know about the penalty framework and some legal insights:

• Basic Penalty Structure: If you fail to file Form 3520 on time or file it incomplete or incorrect, the IRS can impose an initial penalty of $10,000 or more. The “or more” depends on what you didn’t report:
  • If you didn’t report a transfer to a foreign trust (Part I) or a distribution from a foreign trust (Part III), the penalty is typically 35% of the amount you should have reported. For example, if you transferred $100k to a foreign trust and never reported it, the penalty could be $35k (since 35% of 100k = 35k), minimum $10k.
  • If you didn’t report that you’re the owner of a foreign trust (Part II) and the trust didn’t file Form 3520-A, there’s a penalty of 5% of the trust’s asset value that you own per year of non-filing. This can add up across years.
  • If you didn’t report a foreign gift over the threshold (Part IV), the penalty can be 5% of the gift for each month of non-filing, up to 25% of the gift’s value. E.g., you got a $200k gift and forgot to file for 6 months past the due date – they could hit you with 25% of $200k = $50k penalty.
  These penalties are outrageous by design – they are meant to be a big stick to force compliance.
• Additional penalties: If the IRS sends you a notice asking for the form (or missing info) and you still don’t comply within 90 days, additional penalties can accrue. Often it’s another $10,000 for each 30-day period of continued failure after that 90-day window, sometimes again capped by the value of the trust or gift (so you’re not fined more than the amount involved, in theory).
• Interest and possibly more: On top of penalties, interest will accrue on any unpaid penalty amount, increasing what you owe over time. In extreme situations, criminal penalties could apply if it’s proven that the failure to file was willful as part of evading taxes (though Form 3520 issues are usually handled with civil penalties, unless there’s overt tax evasion or fraud tied to it).
• Reasonable Cause Exception: The law does allow penalties to be waived if you can demonstrate reasonable cause for failing to comply and that it wasn’t due to willful neglect. “Reasonable cause” is a tough standard but examples might include:
  • You genuinely never knew of the requirement and it’s a one-time oversight (especially for something like a one-off inheritance, and you correct it promptly upon learning).
  • You tried to get information from a foreign trustee and they refused or delayed, beyond your control.
  • Serious illness or other disaster prevented you from filing.
    You must affirmatively request penalty abatement by writing a reasonable cause letter to the IRS. The IRS will scrutinize your facts. First-time inadvertent foot-faults have a decent chance of abatement, whereas large sophisticated taxpayers might face a higher bar.
• Legal Battles: There have been cases where taxpayers challenged these penalties. For instance, one taxpayer (Mr. Mukhi) faced about $10.9 million in penalties for failing to file Forms 3520 and 3520-A over multiple years for large offshore trusts. He argued that the penalties were unconstitutional (excessive fines) and that the IRS didn’t have authority to assess them without going to court. The Tax Court in 2021 upheld the penalties, essentially saying that such penalties, while huge, were within the law’s intent for deterring noncompliance. They did, however, in some cases (like Farhy v. Commissioner in 2023) find that certain related penalties (like for not filing a Form 5471 for foreign corporations) couldn’t be directly assessed by IRS. But importantly, the Form 3520 penalties (under §6677 and §6039F) are enforceable and the IRS can assess them. In plain speak: If you don’t file, the IRS can send you a bill for, say, $50,000 or $100,000 (whatever the penalty calculation is), and if you don’t pay, they can put liens on you just like a tax debt. To fight it, you often have to pay first then sue for a refund, which is costly.
• Recent Developments: The IRS had a practice of automatically assessing penalties the moment a Form 3520 was filed late (computer-generated penalty notices). After many complaints – including from the Taxpayer Advocate Service – the IRS announced in late 2023 that it would stop automatically issuing these penalties without human review. This is good news: it means if you file a bit late but have reasonable cause, you might not get instantly hit by the system. However, this doesn’t mean you won’t get penalized; it just means a person might review your explanation first.
• Statute of Limitations: Normally, the IRS has 3 years to audit a tax return. But for international information forms like 3520, if you never file the form (or if you file it missing key info), the statute of limitations on the related tax items stays open indefinitely. That is, if you don’t file a required 3520, the IRS could, even 10 years later, examine that year and impose penalties or determine tax consequences from that trust/gift. This is another reason to file – it starts the clock running.

In summary, the consequences for not filing or filing wrong are very serious. Many taxpayers have learned the hard way that ignorance is not bliss in this area. The law’s penalty structure is intentionally harsh to encourage compliance. The best defense is simple: file accurately and on time. If you mess up, be proactive: file as soon as you realize it, and attach a good faith reasonable cause letter. The IRS does have discretion to waive penalties if they believe your story and history.

One silver lining: penalties can sometimes be negotiated or abated. For instance, people have successfully gotten penalties reduced by arguing they had reasonable cause. The Taxpayer Advocate Service may assist in egregious cases. But don’t rely on luck – far better to never end up in that situation by filing properly.

Key Terms and Definitions (Form 3520 Glossary)

Understanding Form 3520 also means understanding the jargon and key concepts involved. Here’s a quick glossary of important terms and what they mean in this context:

• U.S. Person: For Form 3520 purposes, a U.S. person includes U.S. citizens or residents, domestic corporations and partnerships, trusts or estates. Essentially, if you’re subject to U.S. tax and you do one of the reportable actions, you count as a U.S. person who might file the form. (Example: A U.S. green card holder receiving a gift from abroad is a U.S. person who must file if thresholds are met.)
• Foreign Trust: A trust is considered foreign if it’s not governed by U.S. law and if U.S. courts or persons don’t have primary control. In simpler terms, a foreign trust is any trust organized outside the United States. Key features are a foreign trustee or foreign law controlling it. (Example: A trust formed under Swiss law with a Swiss trustee is a foreign trust.)
• Grantor Trust & Owner: Under U.S. tax law, if you create a trust and retain certain powers or benefits (like the ability to revoke the trust, or you’re the beneficiary of it), you might be considered the grantor-owner of that trust. For foreign trusts, if you’re a U.S. grantor with those powers, you’re treated as owning the trust’s assets for tax purposes. Form 3520 Part II is where the U.S. owner reports that ownership annually.
• Beneficiary: A person who has the right to receive distributions from the trust. A U.S. beneficiary of a foreign trust must report any distributions they get (Part III). Also, even if a foreign trust names a U.S. person as beneficiary, that can trigger some of these reporting rules (to prevent “hidden” benefits).
• Distribution: Any money or property that comes out of a trust for the benefit of a beneficiary. It doesn’t have to be cash – use of property, interest-free loans, etc. count as distributions. (Even paying someone’s expenses could count.) Distributions are reported on Part III of Form 3520 by the recipient.
• Foreign Gift/Bequest: Money or property received from a foreign person that the recipient treats as a gift or inheritance. “Foreign person” here means a non-U.S. individual or entity. The IRS sets thresholds (like $100k from foreign individuals) above which these must be reported on Part IV. Gift vs. inheritance: For the form, both are reported the same way. (No tax to the recipient, but need to report if large enough.)
• Section 6039F: This is the section of U.S. tax law that requires reporting of foreign gifts and sets the penalty for not doing so (it’s referenced in Form 3520 instructions). It’s useful to know this term because IRS letters will mention “6039F penalty” if you failed to report a gift.
• Section 6048: The part of the tax code dealing with foreign trusts – covering the requirement to report transfers, ownership, and distributions (and the associated penalty under §6677). It’s essentially the law behind most of Form 3520. If you see references to 6048(a), (b), (c), they correspond to the three categories (transfers, ownership, distributions).
• Form 3520-A: The Annual Information Return of Foreign Trust with a U.S. Owner. This form is like a “trust’s tax return” that a foreign trust files each year to report its financial info to the IRS, when a U.S. person is an owner. The foreign trustee is supposed to file it by March 15. If they don’t, the U.S. owner must file a substitute 3520-A with their Form 3520. It includes schedules (like the Foreign Grantor Trust Owner Statement and Beneficiary Statement) that are given to the U.S. persons involved. Think of Form 3520-A as the companion form to Form 3520 for trusts.
• FBAR (FinCEN Form 114): While not part of Form 3520, the FBAR is often mentioned alongside it. It’s a Report of Foreign Bank and Financial Accounts that U.S. persons file with FinCEN if they have over $10k in foreign accounts. A foreign trust account could trigger an FBAR filing as well. FBAR is separate (filed online to Treasury, not IRS, due April 15 with automatic extension to Oct 15). It’s key to note FBAR != Form 3520; they cover different things, though there’s overlap if the trust had accounts.
• Form 8938 (FATCA): This is another separate form that lives on your 1040 tax return if you have specified foreign financial assets above certain thresholds (e.g., $50k single/$100k joint at year-end for domestic residents, higher for expats). An interest in a foreign trust or a foreign gift might sometimes also be reported on Form 8938, but Form 8938 does NOT replace Form 3520. You might have to file both. Form 8938 is more about asset reporting for individuals under the FATCA law.
• Throwback Tax: A special tax rule for trust distributions. If a foreign trust (typically non-U.S. trust) accumulates income over years and then distributes a lump sum to a U.S. beneficiary, the U.S. applies a punitive “throwback tax” on the portion of distribution that represents earlier-years’ accumulated income. It basically taxes that portion at highest rates of those years plus an interest charge for the deferral. This is what the Schedules in Part III help compute if needed. It’s complicated, but the term “throwback” essentially means taxing as if thrown back into the years the income was earned.
• Qualified Obligation: A specific term for a loan from a foreign trust (or related person) to a U.S. person that meets certain IRS criteria (timely repayments, market interest, proper documentation). If a loan meets these, it’s not treated as a distribution. If it doesn’t, the loan is treated as a distribution. On Form 3520, you declare whether an obligation you received is “qualified” or not.
• Reasonable Cause: This is a general tax concept meaning you had a valid reason for not complying. In context of Form 3520 penalties, showing reasonable cause (and lack of willful neglect) is how you get out of penalties. There’s no fixed definition; it’s based on facts and circumstances – often requires proving you exercised ordinary business care and prudence but still couldn’t comply.

Knowing these terms helps you navigate not just the form, but also any guidance and discussions about it. The IRS instructions and communications will use these phrases regularly. If you encounter them (in a letter or instructions), refer back to this list to recall what they signify.

Key Entities and Relationships in Foreign Trust Reporting

Form 3520 doesn’t exist in a vacuum – it involves various parties and organizations. Understanding who’s who and how they relate can clarify the bigger picture of compliance. Here are the key entities and their relationships in the context of foreign trust and gift reporting:

• Internal Revenue Service (IRS): The U.S. tax authority that requires Form 3520. The IRS is responsible for collecting the form, enforcing penalties, and ensuring compliance. Within the IRS, the International Compliance units handle these forms. The IRS also issues regulations and guidance on foreign trust reporting. Relationship: The IRS is on the receiving end of your Form 3520; they may interact with you (the taxpayer) by sending notices, penalty letters, or requests for information if needed.
• Foreign Trust: The non-U.S. trust that is at the heart of many Form 3520 filings. A foreign trust typically has:
  • A Grantor/Settlor (the person who created and funded it – possibly you if you’re the one filing Part I/II as owner).
  • A Trustee – the person or institution that holds and manages the trust assets under the trust deed. Often this trustee is abroad (could be a trust company or an individual).
  • Beneficiaries – those who are entitled to benefit from the trust (could be you, family members, etc., some of whom might be U.S. persons).
    Relationships: The grantor might be a U.S. person (triggering Part II). The trustee might be responsible for providing info (Form 3520-A, beneficiary statements) to the U.S. persons. Beneficiaries who are U.S. persons must report what they get. Essentially, the foreign trust is the source of data that flows to the IRS via the U.S. persons involved.
• U.S. Taxpayer (Filer of Form 3520): This could be:
  • The U.S. grantor/owner of a foreign trust.
  • The U.S. beneficiary of a foreign trust.
  • The U.S. recipient of a foreign gift or inheritance.
  • An executor of a U.S. person’s estate dealing with these things.
    Relationships: The U.S. taxpayer is the lynchpin who interfaces between the foreign world and the IRS. You gather info from the foreign trust or from your foreign relative who gave a gift, and you report it to the IRS. You may have to prod foreign trustees for documents – a sometimes challenging relationship (some foreign trustees are unfamiliar with U.S. requirements or unwilling to share info, which can put you in a tough spot).
• Foreign Trustee/Foreign Administrators: For a foreign trust, the trustee overseas is an important figure. They might be an institution (like a bank trust department in Switzerland) or an individual.
  Relationships: The trustee should ideally file Form 3520-A and give you statements each year. If they don’t, you – the U.S. owner – have to step in. Some trusts hire a U.S. agent (like a U.S. attorney or accountant) to liaise with the IRS if needed, or to be an official point of contact – which can smooth communications.
• FinCEN (Financial Crimes Enforcement Network): This U.S. Treasury bureau handles the FBAR filings (foreign bank account reports). While FinCEN is separate from the IRS, they share data. Often, someone dealing with foreign trusts/gifts might also deal with FinCEN if, for instance, the trust had a non-U.S. bank account over $10k (triggering an FBAR).
  Relationships: FinCEN and IRS both are interested in offshore assets, but FinCEN via FBAR is about accounts, whereas IRS via Form 3520 is about trusts/gifts. They complement each other. For example, if you report a foreign trust on 3520, the IRS might expect you also filed an FBAR for accounts you have interest in (if any). It’s good to cover all bases because the agencies can flag mismatches.
• Tax Professionals (CPAs/Tax Attorneys/Enrolled Agents): These are the folks who often help taxpayers prepare Form 3520 or resolve related issues.
  Relationships: They act as intermediaries between the taxpayer and IRS. A knowledgeable international tax CPA can contact the IRS on your behalf, help explain complex trust arrangements, and assist in reasonable cause arguments. They also might coordinate with foreign trustees or advisors to get needed info. Essentially, they help manage the relationship between all parties to keep things compliant and penalties at bay.
• Tax Court and Courts: If disputes arise (for example, you get hit with a penalty and you dispute it), eventually the U.S. Tax Court or other federal courts can get involved.
  Relationships: Typically, to challenge a 3520 penalty, one might go to Tax Court (if allowed) or pay the penalty and sue for refund in District Court or Court of Federal Claims. Courts have weighed in on some key cases (as mentioned, Farhy, Mukhi, etc.), which shape how IRS can enforce these penalties. While most people won’t end up in court, the existence of these legal precedents influences how IRS and taxpayers negotiate (e.g., IRS knows if they have a weak position because of a case, they might not pursue certain penalties as aggressively).
• Congress and Treasury: They are the ones who created these rules (Congress wrote the laws in the 90s) and Treasury/IRS issue regulations. Occasionally, law changes happen that affect Form 3520 (for instance, exemptions introduced for certain retirement trusts via Revenue Procedure, or adjustments to penalty procedures after advocacy).
  Relationships: They’re more in the background, but it’s useful to know that these rules aren’t arbitrary – they were enacted to combat offshore tax abuse. Organizations like the Taxpayer Advocate Service (TAS) (an independent arm within IRS that fights for taxpayer fairness) have lobbied Congress and IRS to make these rules more fair and administrable. For example, TAS pushed for relief from automatic penalties, which led to the IRS’s recent policy change.

Relationships Summary: You, as a U.S. taxpayer, stand in the middle:

• On one side, the foreign side (trustees, foreign relatives/donors, foreign institutions holding assets).
• On the other side, the U.S. side (IRS and possibly FinCEN).
  Your job is to bridge the gap by collecting info from the foreign side and reporting it to the U.S. side via forms. If things go smoothly, you’re just a conduit of information. If things go poorly (e.g., foreign trustee doesn’t cooperate, or IRS questions something), you might need help from professionals or might deal with enforcement.

All these entities form a kind of ecosystem ensuring compliance with international tax obligations. Recognizing who the players are and how they connect will help you navigate any issues that come up. For instance, if your foreign trustee balks at giving info, you can explain it’s required for U.S. compliance (maybe involve a U.S. attorney to communicate). If the IRS sends a penalty notice, you know there’s the Taxpayer Advocate or appeals process that might help. Knowing the relationships means you don’t feel alone in the process – you understand each party’s role.

Form 3520 vs Other Forms: FBAR, FATCA, 3520-A, and 709

One point of confusion is how Form 3520 differs from or overlaps with other international reporting forms. Let’s compare Form 3520 with other key forms:

• Form 3520 vs Form 3520-A: These two go hand-in-hand but are filed by different parties. Form 3520-A is the foreign trust’s annual report to the IRS, whereas Form 3520 is your report as the U.S. person. If you’re an owner of a foreign trust, the trust (or you, in lieu) files 3520-A by March 15, providing full trust financials and statements to beneficiaries/owners. You then file Form 3520 by April 15, referencing the info from 3520-A in Part II/III. Think of 3520-A as the trust’s income statement/balance sheet, and 3520 as your summary to IRS that “Yes, I’m involved with this trust and here’s what happened (see attached 3520-A for details).” In short: 3520-A -> filed by trust; 3520 -> filed by U.S. person. Both are required and penalties exist for missing either.
• Form 3520 vs FBAR (FinCEN Form 114): The FBAR is a report of foreign bank and financial accounts and is not an IRS form (though IRS enforces penalties for it). It’s required if you have foreign accounts > $10,000 aggregate. Now, a foreign trust often involves a foreign bank account (the trust’s account). Do you have to include the trust’s account on your FBAR? Possibly yes, if you have a financial interest or signature authority. As the grantor/owner of a foreign trust, the IRS treats you as owning the accounts too (for FBAR purposes).
  • Even as a beneficiary, if you can control the account or make withdrawals, you might have to FBAR it. Key difference: FBAR is about accounts and their balances; Form 3520 is about the transfers, ownership, and receipts from the trust or gifts. They serve different objectives: FBAR is Treasury’s tool to track undeclared offshore bank accounts; Form 3520 is to track flows of funds and assets via trusts/gifts.
• Form 3520 vs Form 8938 (FATCA reporting): Form 8938 (Statement of Specified Foreign Financial Assets) is part of your 1040 tax return (if required) and has higher thresholds (e.g., $50k+ for residents, $200k+ for expats, etc.). It overlaps with FBAR in some ways but is more extensive in others (it covers foreign stocks, interests in foreign entities, etc., not just bank accounts).
  • A foreign trust interest might be considered a specified foreign financial asset. For example, if you’re an owner of a foreign trust, or you’re a beneficiary who knows the trust’s value, you might have to report that interest on Form 8938 (there’s a specific part for foreign trusts). Also, if you received a large foreign gift, technically the money or asset you received, if still held at year-end in some form, could be a foreign asset (though if you brought cash to the U.S. or it’s just sitting in your U.S. bank, then no).
  • However, Form 8938 has an explicit clause that if you already reported something on certain forms (including Form 3520), you might not need to duplicate all details on 8938 – you often just have to tick a box that yes, you filed 3520 for that asset. The two forms complement each other under FATCA rules, but you must consider both. If you meet the Form 8938 asset threshold, file it in addition to Form 3520. It’s not either/or.
• Form 3520 vs Form 709 (U.S. Gift Tax Return): Form 709 is filed by U.S. persons who give gifts, to report gifts and potentially pay U.S. gift tax if over the exemption. A common confusion: If you receive a gift from a foreign person, do you file 709 or 3520? Answer: You file Form 3520 (because you are the recipient of a foreign gift). You do not file Form 709, because 709 is only if you are the donor of a gift.
  • And foreign donors are not subject to U.S. gift tax, so they don’t file 709 either (unless they gift U.S. situs assets perhaps, which is another complexity but in general foreign persons aren’t filing U.S. gift tax returns for gifts to U.S. persons). So: 3520 for inbound foreign gifts; 709 for outbound gifts if you’re gifting someone (and you’re American). They are separate worlds. There’s no tax on receiving a gift (so Form 3520 just reports it), whereas 709 can trigger gift tax if you, a rich uncle in the U.S., gift someone over the exemption.
• Form 3520 vs Form 5471/8865, etc.: These latter forms are for interests in foreign corporations (5471) or partnerships (8865). Sometimes people think a foreign trust is similar to a corporation or something – but no, it’s its own category. If you own a stake in a foreign corporation, you do Form 5471 (which is also complex). If you are a beneficiary of a foreign trust, it’s Form 3520.
  • They are not interchangeable. However, there are cases where a gift from a foreign corporation (which is unusual; corporations usually don’t gift without reason) might actually be re-characterized by IRS as a dividend (taxable) if not properly reported. That’s why they ask on 3520 for gifts from foreign corporations – they want to see if it’s truly a gift or if the corporation is maybe owned by someone related and they are funneling money. That could cross into 5471 territory if you actually own that corporation.

In summary, Form 3520 is unique – it handles foreign trusts and large foreign gifts. But it often intersects with other reporting:

• If you file Form 3520 for a trust, you probably also need that trust’s Form 3520-A filed, an FBAR for any accounts, and maybe a Form 8938.
• If you file Form 3520 for a gift, you might also mention it or part of it on Form 8938 if it’s still an asset you hold.
• If you’re a donor, forget 3520, focus on 709; if you’re a recipient, forget 709, focus on 3520.

Remember: Complying with one form doesn’t exempt you from others if their criteria are met. Each targets a different aspect of international asset transparency. It’s wise, if you have cross-border assets or income, to walk through all potential forms each year (FBAR, 8938, 3520, 5471, etc.) and see which apply. It’s far better to over-report than under-report in this arena.

Frequently Asked Questions about Form 3520

Q: I received $50,000 from my foreign parents. Do I need to file Form 3520?
A: Not yet. The foreign gift reporting threshold is $100,000 from related foreign individuals. $50k alone is below the limit, so no Form 3520 is required for that amount.

Q: Is Form 3520 the same as FBAR or FATCA reporting?
A: No. Form 3520 reports foreign trusts and large gifts. FBAR reports foreign bank accounts. FATCA (Form 8938) reports foreign financial assets. They cover different things, and you might need to file multiple forms.

Q: Can I e-file Form 3520 with my tax return?
A: Generally, no. Form 3520 is a standalone form that usually must be mailed to the IRS (Ogden, UT). It’s not part of your 1040 and most tax software doesn’t e-file it. Always check the latest IRS guidance, but expect to paper-file it.

Q: What happens if I don’t file Form 3520?
A: The IRS can impose hefty penalties – starting at $10,000 and potentially up to 35% of the trust amount or 25% of the gift. They can also treat unreported gifts as taxable income. It’s serious, so file the form if required, or file late with a good explanation to avoid penalties.

Q: Do I have to pay any tax with Form 3520?
A: No tax is calculated on Form 3520 itself. It’s an information return. If a distribution from a foreign trust includes taxable income, that income is reported on your 1040. Gifts are not taxed to the recipient. Form 3520 just reports the transaction.

Q: What’s the difference between Form 3520 and Form 3520-A?
A: Form 3520 is filed by you (the U.S. person) to report your transactions with a foreign trust or receipt of gifts. Form 3520-A is filed by the foreign trust (or by you as a substitute) to report the trust’s financial info to the IRS. Think 3520-A = trust’s return, 3520 = your return.

Q: If a foreign trust doesn’t give me any information, what should I do?
A: Still file Form 3520 as completely as you can. Indicate that the trustee didn’t provide a beneficiary statement or details. You may have to use default calculations for any distribution (which could be less favorable). Also attach a statement explaining your efforts to obtain info – this can help show reasonable cause to avoid penalties for any missing pieces.

Q: Do I need to report foreign real estate or foreign inheritance on Form 3520?
A: Foreign real estate: Owning property abroad isn’t reported on 3520 (unless it’s held in a foreign trust). Foreign inheritance: If you inherit money or property from a foreign person and it’s over $100k, yes – report it as a foreign bequest on Form 3520 Part IV.

Q: Are there exceptions to filing Form 3520?
A: Yes. Certain transfers are exempt. For example, transfers to foreign pension trusts (like Canadian RRSPs) can be exempt by treaty/IRS guidance. Also, if a foreign trust is a tax-exempt charity, transfers to it aren’t reported. These are specific cases – see IRS guidance (Rev. Proc. 2020-17, etc.) for details. When in doubt, assume you must file unless an official exception clearly applies.
