Foreign Gift Tax & Form 3520 Guide 2026

Understand when a U.S. person must report a large gift or bequest from a foreign person, how the Form 3520 thresholds work, what counts as a foreign gift, and how the IRS penalty rules apply.

Foreign Gift Tax Rules for U.S. Persons

Receiving money, securities, real estate, or other property from outside the United States does not automatically mean that the recipient owes U.S. federal income tax on the amount received. For a U.S. person, however, a qualifying foreign gift or bequest can create an information-reporting obligation under Internal Revenue Code §6039F and Form 3520.

The distinction between taxation and reporting is essential. Form 3520 is an information return used to report specified transactions involving foreign trusts and the receipt of certain large gifts or bequests from foreign persons. Under IRC §6039F(b), a foreign gift generally means an amount received from a person other than a United States person that the recipient treats as a gift or bequest. The statute excludes qualified tuition and medical transfers (IRC §2503(e)(2)) and foreign trust distributions (IRC §6048(c)).

For gifts or bequests from a nonresident alien individual or foreign estate, the current IRS Instructions for Form 3520 require Part IV reporting when the aggregate amount received during the taxable year exceeds $100,000. For purported gifts from foreign corporations and foreign partnerships, the 2026 inflation-adjusted section 6039F threshold is $20,573.

The statutory penalty under IRC §6039F(c)(1) for failing to timely report a foreign gift is 5% of the gift amount for each month of failure, up to a maximum of 25%. A statutory reasonable-cause exception applies under IRC §6039F(c)(2) when the taxpayer demonstrates that the failure was due to reasonable cause and not willful neglect.

2026 Foreign Gift Reporting Thresholds

Nonresident alien individual or foreign estate: more than $100,000

Foreign corporation or foreign partnership: $20,573 for 2026

Individual gifts over $5,000

When Must Foreign Gifts Be Aggregated?

Gifts from different nonresident alien individuals and foreign estates must be aggregated when the recipient knows or has reason to know that the donors are related to one another or that one person is acting as a nominee or intermediary for another. For example, $75,000 from one foreign relative and $40,000 from another related foreign relative must be combined into $115,000, triggering Form 3520 Part IV.

Frequently Asked Questions (6)

Not necessarily. A genuine gift or bequest from a foreign person is not included in gross income under IRC §102. The main requirement under IRC §6039F is information reporting on Form 3520 when statutory thresholds ($100,000 for individuals, $20,573 for corporations in 2026) are exceeded.

The IRS Form 3520 instructions require reporting in Part IV when aggregate gifts or bequests received during the tax year from a nonresident alien individual or foreign estate exceed $100,000. Gifts from related foreign individuals must be combined towards this threshold.

IRC §6039F(c)(1) imposes a penalty of 5% of the gift amount for each month or fraction of a month the return is late, up to a maximum of 25%. A statutory reasonable-cause exception applies under IRC §6039F(c)(2) if the taxpayer demonstrates reasonable cause and not willful neglect.

Yes. The IRS requires aggregation when gifts are received from different foreign individuals or estates whom the recipient knows or has reason to know are related. For example, $75,000 from a parent and $40,000 from a sibling totals $115,000, requiring Form 3520 Part IV reporting.

Form 3520 is generally due April 15 of the following year (or June 15 for qualifying expats living abroad). If an income tax return extension is obtained, Form 3520 is extended to October 15. It must be mailed separately to the IRS Service Center, P.O. Box 409101, Ogden, UT 84409.
