Form 3520 Foreign Gift Guide: 2026 Reporting Rules

Executive Summary & Core Form 3520 Principles

Under Internal Revenue Code Section 6039F, U.S. persons (including U.S. citizens, Green Card holders, and resident aliens under the Substantial Presence Test) who receive large foreign gifts or inheritances must file annual information return Form 3520 (Part IV).

While bona fide foreign gifts and bequests are generally not subject to U.S. federal income tax, failure to timely report crossing the statutory thresholds triggers draconian monthly penalties up to 25% of the total gift value. Form 3520 is filed separately from Form 1040 and mailed directly to the IRS Service Center in Ogden, Utah.

What Form 3520 Is

Form 3520 is an information return used by U.S. persons and certain estate-related filers for several international reporting situations. Part IV is the section relevant to receipt of certain large gifts or bequests from foreign persons.

The foreign-gift rules are found primarily in Internal Revenue Code section 6039F. The reporting obligation is informational; it is not, by itself, an income-tax charge on an ordinary bona fide foreign gift.

A Form 3520 filing should not be confused with Form 709, which is generally associated with the U.S. gift-tax reporting obligations of the person making a transfer, or with Form 706, which deals with certain estate-tax matters.

Foreign Gift vs Foreign Trust Reporting

Who Is a U.S. Person for Form 3520 Gift Reporting?

The foreign-gift reporting rules generally apply to U.S. persons. For section 6039F purposes, the term is tied to the Internal Revenue Code definition rather than to immigration status alone.

A U.S. citizen or U.S. tax resident can therefore have a Form 3520 obligation. Visa labels such as H-1B, L-1, or O-1 do not by themselves answer whether someone is a U.S. person for this purpose. The individual's tax residency and other facts must be evaluated.

For example, an H-1B worker who meets the applicable substantial-presence and residency rules may be a U.S. person for federal tax purposes. Conversely, holding a visa does not automatically make someone a U.S. tax resident in every circumstance.

The $100,000 Foreign-Individual / Estate Threshold

For gifts or bequests from a nonresident alien individual or a foreign estate, the current IRS threshold is more than $100,000 during the taxable year.

The threshold is not a lifetime cap and is not a per-transaction threshold. It is generally an aggregate annual threshold for the applicable donor group.

IRS instructions also require aggregation in specified situations where gifts come from different foreign nonresident aliens or foreign estates and the recipient knows or has reason to know that the persons are related or that one is acting as nominee or intermediary for another.

The 2026 $20,573 Foreign-Entity Threshold

A different threshold applies when the purported gift comes from a foreign corporation or foreign partnership. For tax year 2026, the applicable inflation-adjusted threshold is $20,573.

The rule also covers certain foreign persons related to the foreign corporation or partnership when the recipient knows or has reason to know of the relationship.

The IRS uses the term 'purported gifts' because payments from a foreign business entity may not actually qualify as gifts for federal income-tax purposes. The IRS can potentially recharacterize such a payment based on its substance.

Related Donors and Aggregation

The IRS specifically requires aggregation in certain related-donor situations. For foreign individuals and estates, the recipient must aggregate gifts where the donors are related and the recipient knows or has reason to know of the relationship, or where one person is acting as a nominee or intermediary for another.

The related-person definition used in the Form 3520 instructions includes family members such as parents, grandparents, siblings, spouses, children, and grandchildren, as well as certain corporations.

This is why a recipient should not analyze a large family transfer solely by looking at each bank wire separately.

What Happens After You Cross the Threshold?

Crossing the applicable threshold creates a Form 3520 Part IV reporting obligation; it does not mean the entire amount automatically becomes ordinary taxable income.

The IRS instructions require identification of each gift or bequest in excess of $5,000 once the applicable reporting threshold has been exceeded. If the filer must answer 'Yes' but none of the individual gifts or bequests exceeds $5,000, the instructions provide a special entry instead of requiring separate identification of each item.

A recipient should therefore preserve a complete schedule of dates, donors, descriptions, fair market values, relationships, and supporting documents even when some individual transfers are small.

Cash, Real Estate, Securities and Other Property

The Form 3520 rules are not limited to cash wires. A gift or bequest can involve property, including assets other than money.

The relevant issue is the value of the property received and whether the reporting threshold is exceeded. For non-cash property, fair market value documentation can become particularly important.

A recipient should not automatically use the original purchase price of foreign property or an arbitrary exchange-rate conversion. The valuation should be supportable and consistent with the applicable tax rules.

Are Foreign Gifts Taxable to the Recipient?

As a general federal income-tax rule, a genuine gift or bequest that the recipient treats as a gift or bequest is not included in gross income. That is different from saying that every transfer labeled a 'gift' is automatically tax-free.

The characterization of a transfer matters. A payment that is really compensation, business income, a trust distribution, or another taxable receipt should not simply be labeled a gift to avoid tax.

There is also an important special regime for gifts and bequests from covered expatriates. Under section 2801, a U.S. citizen or resident can potentially owe a separate transfer tax on qualifying covered gifts or bequests.

Special Rule: Gifts From Covered Expatriates

The IRS's current Form 3520 instructions point out that a U.S. citizen or resident receiving a gift or bequest from a covered expatriate may also have obligations under section 2801.

Section 2801 imposes a separate tax on certain covered gifts and bequests received by U.S. citizens or residents from covered expatriates. The tax is paid by the U.S. recipient rather than by the donor.

The rules are especially important where the donor formerly was a U.S. citizen or lawful permanent resident and expatriated under the rules defining a covered expatriate.

Form 3520 Due Dates for Individuals

Form 3520 Is Filed Separately From Form 1040

The IRS instructs U.S. persons to file Form 3520 separately from the federal income-tax return. It should not simply be placed inside the Form 1040 package.

The current IRS foreign-gift page gives the mailing address for Form 3520 as the Internal Revenue Service Center, P.O. Box 409101, Ogden, UT 84409.

Because IRS filing procedures can change, taxpayers should verify the current Form 3520 instructions and filing address at the time of filing.

The 25% Form 3520 Foreign-Gift Penalty

For Part IV foreign-gift reporting, the IRS states that a penalty equal to 5% of the value of the gift or bequest can apply for each month, or part of a month, that the required reporting remains late.

The cumulative penalty is capped at 25% of the value of the unreported foreign gift or bequest.

For example, if a $150,000 reportable foreign gift is not timely reported and the full maximum applies, the penalty could reach $37,500. This is an illustration of the statutory cap, not a statement that every late filing automatically receives the maximum penalty.

Reasonable Cause Can Prevent the Penalty

The IRS states that no penalty will be imposed when the taxpayer can demonstrate that the failure to comply was due to reasonable cause and not willful neglect.

Reasonable cause is evaluated based on the facts and circumstances. The taxpayer should provide a clear explanation of what happened, why the filing was late or inaccurate, what steps were taken to comply, and supporting documents where available.

Simply saying 'I did not know Form 3520 existed' does not guarantee relief. The IRS determines reasonable cause case by case.

The Statute-of-Limitations Rule Is More Nuanced Than 'Indefinitely Open'

The original draft stated that failure to file Form 3520 Part IV leaves the IRS statute of limitations open indefinitely. That is too broad.

The IRS's current Form 3520 instructions state that if a complete Form 3520 is not filed by the due date, the assessment period for tax imposed with respect to events reported in Parts I through III can remain open until three years after the required information is reported.

However, IRS materials specifically caution that IRC section 6501(c)(8) does not create that same exception merely because a person failed to report a large foreign gift under section 6039F Part IV.

Therefore, the foreign-gift Part IV failure should not be advertised as an automatic indefinite statute-of-limitations rule. Other tax-law exceptions can still matter depending on the facts.

Foreign Trust Distributions Are Not Automatically Gifts

A transfer from a foreign trust should not automatically be treated as a foreign gift from the trust's settlor or from an individual who funded the trust.

The IRS instructions distinguish foreign-trust distributions from gifts and require qualifying foreign-trust distributions to be reported in Part III of Form 3520.

Foreign-trust distributions can also have income-tax consequences depending on the type of trust, the recipient's status, the trust's income and principal, and the documentation available.

Tuition and Medical Payments Can Be Different

The IRS foreign-gift guidance states that a foreign gift does not include amounts paid directly by a foreign person for the U.S. person's qualified tuition or medical expenses.

That is different from transferring money to the student or patient and allowing the recipient to make the payment themselves. The facts and payment structure matter.

For large education or medical transfers, retain documentation showing who made the payment, to whom it was paid, what expense it covered, and whether the payment fits the applicable statutory exception.

Foreign Gift Documentation Checklist

The IRS does not prescribe a universal 'gift packet' containing a fixed set of documents. The right evidence depends on the donor, asset, transaction history, and whether the transfer could be recharacterized.

Related Forms That May Also Matter

A Form 3520 filing does not automatically satisfy every other U.S. international information-reporting obligation that might apply.

Depending on how the recipient holds or receives foreign assets, separate reporting may apply under FBAR, Form 8938, foreign-trust rules, or other tax provisions.

Conversely, filing Form 3520 does not mean every foreign account, trust, or asset must be reported on the same form.

2026 Form 3520 Decision Process

Foreign Currency and Valuation

When a reportable gift is received in a foreign currency or as non-cash property, the recipient should maintain a supportable valuation record.

For cash or bank transfers in a foreign currency, preserve the transaction date, amount in the original currency, exchange-rate methodology, and U.S.-dollar calculation used for reporting.

For property, retain appraisal or other valuation evidence appropriate to the asset. A large foreign real-estate gift can therefore require substantially more documentation than a simple bank transfer.

If You Discover an Old Unreported Foreign Gift

Do not assume that submitting a blank or incomplete Form 3520 today automatically resolves an older reporting problem.

First determine what tax year was affected, whether Part IV actually applied, whether the transfer was truly a gift, whether foreign-trust or section 2801 rules apply, and whether other international information returns were required.

A late Form 3520 should generally be accompanied by an appropriate reasonable-cause explanation when the taxpayer believes reasonable cause exists. The IRS determines whether the explanation qualifies.

Where the unreported amount is substantial, the taxpayer should consider professional advice before filing because an inaccurate characterization can create issues beyond the information return itself.
