Statutory Regulations & IRS Aggregation Rules
Under 26 U.S.C. Section 6039F, U.S. persons receiving certain large foreign gifts or bequests are subject to international information-reporting requirements. The applicable threshold depends on the type of foreign person providing the gift, and related foreign persons may need to be aggregated. Key statutory rules include:
- Aggregation of Related Donors (IRS Notice 97-34): For the $100,000 threshold applicable to gifts from a nonresident alien or foreign estate, gifts from related foreign persons may need to be aggregated when the recipient knows or has reason to know they are related. For example, $60,000 from a foreign parent and $50,000 from another related foreign donor can produce an aggregate amount of $110,000 when the applicable relationship rules are satisfied.
- General Federal Income-Tax Treatment: A bona fide gift or bequest that qualifies for the IRC Section 102 exclusion is generally not included in the recipient's gross income. Form 3520 Part IV is an information-reporting requirement, but special rules such as IRC Section 2801 can apply to certain gifts or bequests from covered expatriates.
- Separate Mailing Address: Form 3520 is NOT attached to your Form 1040. It must be mailed separately to the IRS Internal Revenue Service Center in Ogden, UT.

Frequently Asked Questions (FAQ)
Under 26 U.S.C. Section 6039F, a U.S. person who receives gifts or bequests from a nonresident alien individual or foreign estate must generally report them on Form 3520 (Part IV) when the applicable aggregate amount exceeds $100,000 during the tax year. Gifts from related foreign persons are aggregated under the applicable rules. For purported gifts from foreign corporations or foreign partnerships, the 2026 aggregate reporting threshold is $20,573, adjusted annually for inflation; amounts from related foreign corporations, partnerships, and related foreign persons are aggregated.
Generally, a bona fide foreign gift or inheritance that is excluded from gross income under IRC Section 102 is not treated as ordinary U.S. federal income. Form 3520 is generally an information-reporting return rather than an income-tax return for the gift itself. However, special rules apply to certain gifts or bequests from covered expatriates under IRC Section 2801, and other facts can produce different federal or state tax consequences.
For Form 3520 Part IV, gifts from a nonresident alien or foreign estate are aggregated with gifts from foreign persons the recipient knows or has reason to know are related to that donor or estate. For example, $60,000 from a foreign father and $50,000 from a foreign mother may need to be aggregated when the applicable related-party rules are satisfied, producing $110,000 for the reporting threshold.
Form 3520 is generally due on the 15th day of the fourth month after the end of the U.S. person's tax year. For calendar-year taxpayers this is generally April 15. U.S. citizens and residents living outside the United States and Puerto Rico, and qualifying military or naval personnel serving abroad, generally have a June 15 deadline. A timely Form 4868 extension for the income-tax return also extends Form 3520, but not beyond the 15th day of the 10th month after the tax year; for calendar-year taxpayers, that is generally October 15.
Under Section 6039F(c), a taxpayer may be subject to a penalty equal to 5% of the value of the unreported foreign gift or bequest for each month, or part of a month, the failure continues, up to a maximum of 25% of the gift or bequest. No penalty is imposed when the taxpayer establishes that the failure was due to reasonable cause and not willful neglect.
A taxpayer who failed to timely or accurately file Form 3520 Part IV may provide a reasonable-cause statement explaining why the failure was due to reasonable cause and not willful neglect. For delinquent international information returns, the IRS also provides specific submission procedures. Reasonable-cause statements for Form 3520 are considered under the applicable Form 3520 and IRC Section 6039F rules; streamlined offshore procedures are not a generic substitute for the Form 3520 reasonable-cause process.
