Form 3520: Reporting Foreign Gifts to US Family Members ($100,000 Threshold)

When a non-resident parent wires money to a US-citizen or green-card-holder child for tuition, a down payment, or an inheritance, Form 3520 is required once the aggregate crosses $100,000 in a calendar year. A full walkthrough of the thresholds, the 25% penalty for late filing, and the three transfer patterns that catch families off guard.

The Quiet Rule That Catches International Families

A non-resident parent in China, India, Korea, or the UK transfers $200,000 to their US-citizen daughter as a down payment on a first home. The parent has no US tax obligation. The daughter receives the money tax-free (gifts are never taxable to the recipient in the US system). Everyone assumes nothing further is required.

Then, two years later, a letter arrives from the IRS: the daughter owes a $50,000 penalty for failing to file Form 3520.

Form 3520 is the "Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts." It is not a tax form — no tax is owed. It is an information return, which is why most families miss it. But the penalty for missing it is severe: 5% of the unreported amount per month, up to 25% total. On a $200,000 gift, that's a $50,000 penalty for what the recipient perceived as a routine family wire.

This guide walks through every situation where Form 3520 applies, the threshold math, the correct filing mechanics, and how to fix missed prior-year filings before the IRS assesses the penalty.

Who Has to File

Form 3520 is filed by the US recipient, not the foreign giver. The giver has no US obligation (they are a non-resident with no US connection).

"US recipient" means any of:

US citizen (anywhere in the world)
Lawful permanent resident (green card holder)
US tax resident by substantial presence test
US domestic entity (corporation, LLC, partnership, estate, trust)

If the recipient is in any of those categories and receives a foreign gift above threshold, Form 3520 is due.

The Thresholds: When Filing Is Triggered

Part IV: Gifts from Foreign Individuals or Foreign Estates

Threshold: $100,000 per calendar year, aggregated across all gifts from the same foreign individual or foreign estate.

This is the rule that catches families. The $100,000 is not per-transfer — it is the total across the year from that person. A non-resident parent who transfers $60,000 in March and $50,000 in November triggers the filing requirement because the aggregate is $110,000.

Gifts from related foreign persons are also aggregated. If a non-resident father and a non-resident mother each gift their US-citizen child $70,000, the total from "related persons" is $140,000 and Form 3520 is required. The IRS defines "related" through §267 and §707 of the Internal Revenue Code; parents, siblings, grandparents, and spouses are all treated as related.

Part IV: Gifts from Foreign Corporations, Partnerships, or Other Entities

Threshold: $18,567 for 2026 (inflation-adjusted annually).

Much lower threshold, which catches business-adjacent transfers. If a non-resident's foreign company wires money to their US-citizen child, and the company is treated as a foreign entity (not an individual), the lower threshold applies.

Example: a non-resident father owns a Hong Kong company. The Hong Kong company wires $20,000 to the father's US-citizen daughter for living expenses. That's a reportable gift from a foreign entity, triggering Form 3520 even though $20,000 is far below the personal gift threshold.

Parts II and III: Foreign Trust Transactions

Separate triggers for:

US person establishing or transferring to a foreign trust (Part I)
US person receiving a distribution from a foreign trust (Part III)
US person treated as owner of a foreign trust (Part II)

These apply in more specialized situations — typically when a US person is a beneficiary of a family trust established overseas. The rules are complex and usually require a cross-border tax professional.

What Counts as a "Gift"

The IRS definition of a foreign gift is broad. It includes:

Cash transfers (wire transfers, Western Union, crypto-to-crypto sends that are effectively gifts, etc.)
Gifts of property (real estate, vehicles, jewelry)
Inheritance from a foreign-deceased person (usually excluded as "bequests" with separate rules, but transfers during lifetime are gifts)
Tuition paid directly by a foreign person to a US school — technically a gift to the student

It does NOT include:

Payments directly to a US medical provider for medical expenses (excluded by statute)
Payments directly to a US educational institution for tuition (technically excluded, but see caveat below)
Loans with bona fide repayment obligations and interest (not gifts)
The foreign person's purchase of goods or services at fair market value (not a gift)

The Tuition/Medical Exclusion Caveat

The exclusion for tuition and medical applies only when the foreign person pays the institution directly. If the foreign parent wires money to the US student's personal bank account, and the student then pays tuition, the money is a gift under Form 3520, even though it was used for tuition.

The structural fix is to have the foreign parent wire the tuition payment directly to the university. This takes the transfer out of the student's bank account entirely and qualifies for the exclusion.

The Three Transfer Patterns That Trigger Form 3520

Pattern 1: Down Payment for First Home

Scenario: US-citizen daughter is buying a house. Non-resident parents wire $250,000 for the down payment.

Gift amount: $250,000
From foreign individual: yes
Threshold ($100,000): exceeded
Form 3520 required: yes
Reported in Part IV of Form 3520

This is the most common scenario that blindsides families. The down payment is a single large transfer, easy to track, and easy to flag if missed.

Pattern 2: Tuition Paid Through Student's Personal Account

Scenario: Non-resident parent wires $60,000 to US-citizen student's Bank of America account for a semester of tuition and living expenses. The student pays tuition ($35,000) directly to the university and uses the rest for rent and food.

Gift amount: $60,000 (the full wire, not just the non-tuition portion)
From foreign individual: yes
Threshold: if this is the only transfer in the year, $60,000 is below $100,000 — no filing required
But: if the parent also wires $50,000 later in the same year, aggregate is $110,000 — filing required

The student does not need to segregate the tuition portion; the full wire counts as a gift because the parent did not pay the university directly.

Pattern 3: Inheritance During Lifetime

Scenario: Non-resident grandfather gifts $300,000 to US-citizen grandchild to "start his life." Not tied to any specific use.

Gift amount: $300,000
From foreign individual: yes
Threshold: exceeded
Form 3520 required: yes
Note: if this occurs in the year the grandfather dies, special rules apply — gifts within 3 years of death may recharacterize under estate rules. Not typically a US concern (grandfather is non-US person) but relevant in structuring.

How to File Form 3520

Filing Mechanics

Separate from your 1040: Form 3520 is filed separately. It is mailed to a different address than your regular tax return.
Mailing address: Internal Revenue Service Center, P.O. Box 409101, Ogden, UT 84409
Due date: April 15 of the year following the gift. Same due date as Form 1040.
Extension: automatic if you file Form 4868 extending your 1040; the Form 3520 extension follows. The extended due date is October 15.
E-filing: not available for Form 3520. Paper filing only. Mail by certified mail with return receipt.

What Goes on Form 3520

Part IV (the common section for gifts from foreign individuals and foreign entities) asks:

Line 54: Date of gift
Line 55: Description of property received (cash, real estate, etc.)
Line 56: Fair market value of gift
Line 57: Donor information (name, address, identifier)

You generally do NOT need the donor's US tax ID — a foreign individual typically doesn't have one, and you can report them with a description and their foreign address.

If the total gifts from foreign individuals in the year exceeded $100,000, list each donor and amount, even if individual gifts were below $100,000.

If the total from foreign entities exceeded $18,567, list each donor and amount.

Required Documentation

Keep but do not file:

Copy of the wire transfer confirmation
Copy of the giver's identifying information (passport copy, tax ID)
Statement of relationship to the giver
If applicable, valuation documents for non-cash gifts

The IRS may request these during audit; having them organized saves time.

The Penalty for Not Filing

Base penalty: 5% of the unreported gift amount per month, up to 25% total.

For a $200,000 unreported gift, the penalty can reach $50,000 (25% × $200,000).

The penalty applies to:

Failure to file at all
Filing after the due date (even if you file later voluntarily)
Filing an incomplete or incorrect Form 3520

Important: the penalty is on the recipient, not the giver. The foreign parent faces no US penalty. The US-citizen child does.

Reasonable Cause Defense

The IRS may waive the penalty if you can show "reasonable cause" — typically that you were unaware of the filing requirement and that a reasonable person in your position would not have known.

In practice, reasonable cause is harder to establish than it sounds. The IRS position has hardened: "lack of knowledge" alone is often not accepted, because the Form 3520 requirement has been in effect since 1996.

Factors that help establish reasonable cause:

You are a recent immigrant (less than 3 years US tax resident)
You did not have a US tax preparer
The foreign gift was an unexpected event (inheritance, emergency family situation)
You voluntarily came forward before IRS audit

Factors that hurt:

You had a CPA who should have asked about foreign gifts
You have been a US resident for many years
You filed Form 1040 with all other disclosures but omitted 3520
Multiple years of unreported gifts

How to Fix Missed Prior-Year Filings

If you discover that you should have filed Form 3520 for a prior year and didn't, you have two paths:

Path 1: Delinquent International Information Return Submission Procedure

If you have not received an IRS audit letter yet, and you can show reasonable cause, file the late Form 3520 with an attached Reasonable Cause Statement explaining why it was missed.

Mail to the Ogden, UT address
Include a letter explaining the delay
Attach any documentation supporting your reasonable cause claim
Mark the return clearly as "Delinquent — Reasonable Cause Statement Attached"

The IRS may or may not accept the reasonable cause. If they do, no penalty. If they don't, the 25% penalty applies.

Path 2: Streamlined Filing Compliance Procedures

If you have broader non-filing issues (not just Form 3520, but also unreported foreign income, foreign bank accounts not reported on FBAR, etc.), the IRS Streamlined Filing Compliance Procedures may be appropriate. This is a more comprehensive and complex path typically requiring a tax professional.

Path 3: Don't File and Hope

Not recommended. The IRS cross-references 3520 filings against:

FBAR filings (any bank account receiving large wires)
1099-INT on interest earned
Bank BSA-reported cash transfers
Foreign tax authority data-sharing under FATCA and MCAA

The likelihood of detection is high, especially for transfers over $100,000. When detected, the penalty applies in full without reasonable-cause protection (because you chose not to come forward).

Interaction With Wyoming LLC and Other Structures

Gifts to a Wyoming LLC You Own

If a non-resident parent gifts funds to your Wyoming LLC (rather than to you personally), the analysis is:

A gift to a disregarded-entity LLC owned by a US person is treated as a gift to the US person (the disregarded entity is transparent)
A gift to a C-corp-elected LLC is a gift to the corporation; the corporation would recognize it but no Form 3520 applies to corporations (different reporting regime under §6038)

Most commonly, gifts flow to the individual (you) rather than to the LLC. If the parent wants to fund business operations, the transfer is typically documented as a capital contribution or a member-loan, not a gift.

Gifts to a Foreign Parent Through a US Citizen

If the transfer is going from a US person to a foreign person — the reverse direction — Form 3520 does not apply. Instead, the US person may have gift tax obligations (under separate rules, annual exclusion $18,000 per donee for 2026) and potentially Form 709 filing.

Practical Scenario: Breaking Down a $500,000 House Purchase

Non-resident parents in India want to help their US-citizen daughter buy a $600,000 house. They can contribute $500,000. How should they structure it?

Option A: One-Time Wire to Daughter's Account

Single transfer: $500,000
Form 3520 Part IV: required, $500,000 reported
No tax owed; filing is routine
Daughter files Form 3520 by April 15 of following year

Option B: Two Wires Split Across Years

Transfer $250,000 in December of Year 1
Transfer $250,000 in January of Year 2
Each year's aggregate is $250,000, above $100,000
Form 3520 required for both years

Splitting across years doesn't help reduce reporting (both years are above threshold). It does help if the $100,000 threshold is close; for example, $50,000 in Year 1 and $50,000 in Year 2 would each be below threshold.

Option C: Structured as a Loan

Parents loan $500,000 to daughter with a promissory note, fair-market interest rate, and real repayment terms
This is not a gift — not reportable on Form 3520
But: if the loan is forgiven later, the forgiveness is a gift in that year
And: the daughter owes interest to the parents, which is taxable to the parents (and creates 1042-S reporting for foreign-source US interest)

Option D: Parents Buy the House Directly

Parents purchase the house in their own (foreign) name
Daughter lives in it
No gift, no Form 3520
But: parents now have US real estate, which may trigger FIRPTA on eventual sale and other reporting

Each option has different reporting, tax, and control implications. The one-time wire (Option A) with a routine Form 3520 filing is usually the simplest.

When to Get Professional Help

You can self-file Form 3520 for a straightforward cash gift. Get professional help when:

The gift involves a foreign trust (Parts II, III of Form 3520)
The giver is a foreign corporation with complex ownership
You missed a prior year and are trying to claim reasonable cause
The gift is non-cash (real estate, art, business interest) requiring valuation
You are receiving from multiple foreign family members and the aggregation rules are unclear
The giver is on an OFAC sanctions list (specific rules apply)

Summary: The Key Rules

Form 3520 is filed by the US recipient, not the foreign giver
Threshold: $100,000 per year from foreign individuals / $18,567 from foreign entities
Aggregation: all gifts from one person (and related persons) combine
Due: April 15, same as Form 1040, mail to Ogden, UT
Penalty: 5%/month up to 25% for late filing
No tax owed on the gift itself — it is information-only
Tuition/medical exclusion: only if foreign person pays institution directly
Fix missed filings with reasonable-cause statement before IRS discovers

Form 3520 is one of those quiet rules that punishes ignorance. The form itself takes an hour to complete. The penalty for not knowing to file it can reach $50,000+ on a normal family wire. If you are a US-citizen or green-card-holder receiving any meaningful transfer from non-resident family members, this is the filing to know about — and the one to calendar every April.
