The Mandatory IRS Form 3520 Filing
If you are a U.S. citizen, Green Card holder, or resident alien (including H-1B, L-1, or O-1 visa holders meeting the Substantial Presence Test) and you receive a large financial gift or inheritance from a foreign individual, you are subject to strict IRS reporting rules.
While there is no actual tax liability on the gift (the recipient does not pay tax on gifts), you are legally required to file Form 3520 (Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts) with the IRS.
The purpose of this form is purely informational, allowing the IRS to verify that the money is a genuine gift and not hidden taxable income or foreign trust distributions.
2026 Reporting Thresholds & Automatic Penalties
The thresholds for triggering a Form 3520 obligation for the 2026 tax year are as follows:
Mandatory filing if you receive an aggregate total of more than $100,000 in cash, real estate, or other assets from nonresident alien individuals during the tax year.
Mandatory filing if you receive an aggregate total exceeding $20,573 (adjusted for inflation in 2026) from foreign business entities.
Failing to file Form 3520 on time carries an automatic penalty of 5% of the total gift value for each month it is late, up to a maximum cap of 25%. For example, filing a Form 3520 late for a $150,000 down payment gift from your parents can trigger an automatic $37,500 penalty.
Reasonable Cause & How to File Late
If you missed the tax deadline and need to file Form 3520 late, do not simply send it in without explanation. Doing so will trigger an automatic penalty assessment notice from the IRS.
Reasonable Cause Statement: You must attach a detailed, signed statement showing 'Reasonable Cause' for the delay (such as medical emergency, natural disaster, reliance on professional tax advice, or a genuine lack of knowledge due to first-time resident status). If the IRS accepts your Reasonable Cause letter, they will waive the penalty.
Filing Location: Form 3520 is a paper-filed form. It must be mailed to the IRS Internal Operations Center in Ogden, Utah, separate from your standard Form 1040 tax package.

Are foreign gifts taxable to the recipient?
No. The United States does not impose income tax on gifts received by U.S. residents from foreign sources. However, the reporting via Form 3520 is mandatory if you meet the threshold.
How do I determine if I am considered a resident alien for tax purposes?
You must count your days of presence using the IRS weighted math rules. Check your status using our [Substantial Presence Test Calculator](/usa/substantial-presence-calculator) or read our [Substantial Presence Guide](/usa/guides/tax-residency/substantial-presence-test-spt-rules).
Gift Thresholds
While foreign gifts are not taxable in the U.S., filing Form 3520 is a mandatory informational requirement. Late filings carry heavy automatic monthly penalties.
