Missed Form 3520 for a Foreign Gift?

At a glance

A U.S. person generally must report gifts or bequests exceeding $100,000 during the year from a nonresident alien individual or foreign estate, including amounts aggregated under related-donor rules.
A gift can be reportable even when it creates no income tax. Different rules apply to foreign companies and trusts.
Start with the donor, amounts, dates and filing history. A late-filing approach and any reasonable-cause statement depend on the facts.

Did parents or other family members abroad send you money for a home, tuition or everyday costs? A genuine foreign gift is generally not taxable income to you, but a large gift may still need to be reported on Form 3520.

The form’s full name is Annual Return To Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts.

The requirement is easy to miss because:

The gift usually creates no U.S. income tax
The foreign donor usually has no U.S. filing obligation
The money may have been wired straight into a U.S. bank account and
Form 3520 is filed separately from the regular income tax return.

A late Form 3520 can carry a penalty of up to 25% of the gift, even when no income tax is owed on the money. This article explains when the form is required, how a late filing works, and what a reasonable cause statement has to cover.

Is a foreign gift taxable?

Generally, no. A genuine gift from a foreign person is not included in the recipient's gross income just because the money was received.

Form 3520 is an information return. For a gift from a foreign individual or a foreign estate, Part IV asks for the date of the gift, a description of the property and its fair market value.

Owing no tax does not remove the reporting requirement. A taxpayer can owe nothing on the gift and still face a significant penalty for failing to file.

One case is treated differently. A gift from a covered expatriate may be subject to Section 2801 tax. The current Form 708 reporting rules apply to covered gifts received on or after January 1, 2025. A covered expatriate is, broadly, a former U.S. citizen or former long-term green card holder who met certain tests on leaving. Subject to exceptions, a U.S. recipient reports covered gifts and bequests on Form 708 and pays 40% tax on the annual total above $19,000 for 2025 or 2026. Residency here uses the estate and gift tax domicile rules, which differ from income tax residency. Form 3520 may be required as well.

Who has to report a foreign gift?

Form 3520 applies when the recipient is a U.S. person. That generally includes:

A U.S. citizen
A U.S. resident alien for tax purposes and
A domestic corporation, partnership, trust or estate.

A nonresident alien is generally not a U.S. person for this purpose.

Visa type alone does not decide the answer. An F-1, H-1B, L-1 or O-1 holder's obligation depends on whether that person was a U.S. tax resident on the date the gift was received. That can turn on the substantial presence test, the exempt years available to students and scholars, and any residency election made for the year.

What is the reporting threshold?

The threshold depends on who gave the gift.

Donor	Form 3520 is required when the total for the tax year is	Reported on
A nonresident alien individual or a foreign estate	More than $100,000	Part IV, line 54
A foreign corporation or foreign partnership	More than $20,116 for 2025, or more than $20,573 for 2026	Part IV, line 55

The test looks at the total received during the year. The size of each wire transfer does not matter.

Gifts from different people are added together when the recipient knows, or has reason to know, that the donors are related to each other. The same applies when one donor is acting as a nominee or intermediary for another. Money a parent sends through a sibling, a relative or a family friend can still be treated as coming from the parent.

Once the total passes $100,000, each gift over $5,000 is listed separately on line 54.

Example 1: Several transfers from one parent

In one year, a U.S. resident receives four transfers of $30,000 each from her father, who lives in China and is not a U.S. person.

The total is $120,000. Form 3520 is generally required.

Example 2: Gifts from both parents

In one year, a taxpayer receives $70,000 from his nonresident father and $60,000 from his nonresident mother.

The parents are related persons, so the gifts are generally combined. The total is $130,000, and Form 3520 is generally required.

Example 3: Exactly $100,000

A taxpayer receives exactly $100,000 from one nonresident alien and nothing else from related persons during the year.

The threshold is more than $100,000, so this gift alone generally does not trigger Part IV. The taxpayer should still confirm that no other gift, and no non-cash property, has to be added.

What if the money came from a parent's company?

A transfer from a foreign corporation or partnership falls under the much lower threshold in the table above. The IRS can also recharacterize a purported gift from a foreign entity as income, based on what the payment really was.

A payment from a parent's company should therefore not be reported automatically as a personal gift from the parent, even when the parent owns 100% of the company. Before filing, review:

The legal name of the sender on the bank record
How the company's books recorded the payment: a shareholder distribution, salary, a loan or a receivable
Whether the company has other shareholders and
Whether the parent first received the funds personally and then made the gift.

For gifts from foreign corporations and partnerships, line 55 also asks for the donor's name and address.

What counts as a genuine gift?

Writing "gift" on a wire transfer does not make it a gift for U.S. tax purposes. The facts should show that:

The donor gave the money voluntarily
The recipient has no obligation to repay it
It was not payment for services
The recipient gave no stock, property or other benefit in exchange
It was not a business distribution, an investment or a loan and
It did not come from a foreign trust.

A loan, a salary payment, a company distribution or money held for someone else has different tax and reporting consequences. A distribution from a foreign trust is generally reported in Part III of Form 3520, not in Part IV.

Tuition and medical payments

Qualified tuition paid directly to a school, and medical expenses paid directly to a provider, are not treated as foreign gifts for this purpose.

The result can differ when a parent sends cash to the student, who then pays the school. Keep the bill, the payment record and the name of the party that actually received the money.

Does it matter which account received the money?

No. A deposit straight into a U.S. bank account does not remove the Form 3520 requirement, and neither does leaving the money in an account abroad.

A recipient who owns or controls a foreign account may also have to file an FBAR or Form 8938. Form 3520 does not replace either one.

When is Form 3520 due?

For a calendar-year individual, the due date follows the income tax return.

Situation	Due date	What the form needs
General rule	April 15 of the year after the gift	Nothing extra
U.S. citizen or resident who lives outside the United States and Puerto Rico and whose main place of business or post of duty is also outside them, or who is in military service abroad	June 15	Check line 1j and attach a statement saying which condition applies
The income tax return was validly extended	October 15	Check line 1k and enter the form number of the extended return, such as 1040

October 15 is the latest date. A taxpayer abroad who receives a further extension of the income tax return to December 15 does not get more time for Form 3520.

For a gift received in 2025, the dates are April 15, June 15 and October 15, 2026.

Where is Form 3520 filed?

Form 3520 is not attached to Form 1040. It is mailed separately to:

Internal Revenue Service Center
P.O. Box 409101
Ogden, UT 84409

The form is still filed on paper. Confirm the address in the current instructions before mailing, because IRS addresses change.

The form is also no longer issued year by year. The current version (Rev. December 2023) has a line where the filer writes in the calendar year. Each year with a reportable gift still needs its own form, and only a complete form with every required attachment counts as filed.

What is the penalty for filing late?

Under Section 6039F, the penalty for failing to report a foreign gift on time is 5% of the gift for each month the failure continues, up to a maximum of 25%.

For example, a taxpayer who received a reportable gift of $300,000 and filed Form 3520 a year late faces a potential penalty of:

$300,000 × 25% = $75,000

The penalty is measured by the gift, not by any unpaid tax. The IRS may also determine the income tax treatment of the unreported gift itself.

Does every late Form 3520 lead to a penalty?

No. The law provides that no penalty applies when the failure was due to reasonable cause and not willful neglect.

Reasonable cause is not established just because:

The taxpayer did not know about Form 3520
It was a first mistake
No tax was due on the gift
The donor was a parent
A tax preparer did not ask about foreign gifts, or a bank gave no warning or
The taxpayer filed voluntarily before receiving an IRS notice.

The IRS weighs all the facts and circumstances. The general question is whether the taxpayer used ordinary care and prudence and was still unable to comply on time.

How does the IRS handle a late Form 3520 today?

Two points describe current practice.

First, in October 2024 the IRS announced that it had stopped automatically assessing a penalty when a late Form 3520 reporting a foreign gift arrives. The National Taxpayer Advocate reported the change, and the IRS now reviews a reasonable cause statement before deciding whether to assess.

Second, the IRS's delinquent international information return procedures set out the route. A taxpayer who is not under a civil examination or criminal investigation, and has not already been contacted by the IRS about the missing form, should:

File the late Form 3520 through the normal Form 3520 process
Attach a reasonable cause statement, when claiming reasonable cause and
Write "Reasonable Cause Statement attached" at the top of the first page.

None of this guarantees relief. The IRS can still conclude that reasonable cause was not shown and assess the penalty.

How is a late Form 3520 filed?

A typical late filing for a foreign cash gift follows seven steps.

1. Confirm that the form was required

A large wire from abroad does not by itself mean Form 3520 was due. Check whether:

The recipient was a U.S. person when the money arrived
The donor was a nonresident alien individual or a foreign estate
Gifts from related donors have to be combined
The total for the year exceeded $100,000
The payment was a genuine gift and
The money came from a foreign company, a foreign trust or a covered expatriate.

2. Prepare a separate form for each year

Use the current Form 3520 and write in the calendar year of the gift. A taxpayer who missed two years files two forms.

3. Complete the identifying information and Part IV

For a cash gift from a nonresident alien or a foreign estate, that generally means the identifying information on page 1 and Part IV: line 54, plus the yes-or-no questions on lines 55 and 56. The signature block is on page 6. Each gift over $5,000 is listed with its date, description and value. When no single gift exceeded $5,000, the instructions provide a short notation to enter in place of an itemized list.

4. Get professional help with the reasonable-cause statement

The statement should explain the facts behind the late filing: what you understood, what advice you received, when you discovered the requirement and what you did next. The timeline should be consistent with your returns and supporting records.

A reasonable-cause statement calls for careful review of your circumstances. We do not recommend preparing it yourself or relying on a general template.

5. Add the required notation

Write "Reasonable Cause Statement attached" at the top of the first page of the late Form 3520.

6. Sign and mail the complete filing

Form 3520 must be signed. Use a mailing method that gives tracking and proof of delivery, and keep a full copy of everything sent.

7. Be ready for IRS correspondence

Even with a statement attached, the IRS may ask for more information or issue a penalty notice. The taxpayer may then need to resubmit the explanation, provide supporting documents, request penalty abatement, or take the case to the IRS Independent Office of Appeals. A representative can respond on the taxpayer's behalf with Form 2848.

The first filing should be prepared on the assumption that the facts will be reviewed later.

What records should be kept?

A taxpayer should generally keep:

Foreign and U.S. bank statements, and the confirmation for each wire or transfer
A written gift letter or donor declaration
The donor's full name, address and country, and evidence of the donor's foreign status
Documents showing the relationship between donor and recipient
Documents supporting the source of the donor's funds
Records showing the purpose and use of the gift
Currency conversion calculations, when the gift was not in U.S. dollars
A copy of the original income tax return
The completed Form 3520 and the reasonable cause statement and
Proof of mailing and delivery.

A formal gift agreement is not always legally required. Clear paperwork still helps show that the transfer was a gift, and not income, a loan, a business payment or a trust distribution.

Does Form 1040 have to be amended?

Not always. A late Form 3520 can generally be filed without amending Form 1040 when:

The money was a genuine, tax-free gift
No taxable income was left off the return
The original Form 1040 was otherwise correct and
The only error was the missing Form 3520.

More corrections may be needed when:

The gifted funds sat in a foreign account that earned unreported interest or investment income
An FBAR or Form 8938 was required and not filed
The payment actually came from a foreign trust
The "gift" was really compensation or business income or
Other foreign assets or entities were not reported.

Common mistakes with a late Form 3520

Common problems include:

Assuming a gift is not reportable because it is not taxable
Testing each wire separately when the test is the annual total
Failing to combine gifts from related donors
Reporting a payment from a parent's company as a personal gift without reviewing the company's records
Treating a foreign trust distribution as a Part IV gift
Attaching Form 3520 to Form 1040 when it has to be mailed separately
Filing the form with no reasonable cause statement, or with a generic template that does not match the facts
Writing only "I did not know" without explaining the circumstances
Blaming a tax preparer without saying what information the preparer was given
Leaving out facts that look unfavorable
Waiting months after discovering the problem
Omitting "Reasonable Cause Statement attached" from the first page
Keeping no proof that the IRS received the filing and
Assuming that filing voluntarily guarantees no penalty.

Should I wait for an IRS notice?

Generally, waiting increases the risk.

The IRS's delinquent return procedures are written for taxpayers who find the missing form before the IRS contacts them. Filing voluntarily does not guarantee relief, but acting promptly helps show that the taxpayer took the problem seriously once it was discovered. After the IRS has made contact, both the available procedure and the reasonable cause analysis become harder.

Final thoughts

A foreign cash gift can be completely tax-free and still create a major U.S. reporting obligation.

For a late Form 3520, the questions that matter most are:

Was the recipient a U.S. person when the gift was received?
Was the donor a foreign individual or a foreign estate?
Did the total for the year exceed $100,000?
Were related donors or intermediaries involved?
Was the payment a genuine gift?
Did the money come from a foreign company or a foreign trust?
Are an FBAR or Form 8938 also required?
Do the facts support a credible reasonable cause explanation?

A late Form 3520 is more than a missing form to fill in. How the payment is classified, what records support it, how the form is filed and what the statement says can all affect whether a penalty of up to 25% of the gift applies.
