Most people assume that because a foreign gift is not taxable, there is nothing to file. That assumption is what generates the penalty.
If you have received a large gift from a parent, relative, or other person living outside the US, the first thing most people want to know is whether they owe tax on it. The answer is usually no. A gift from a foreign person is generally not taxable income to the US recipient, and no income tax is owed simply because the money or property arrived.
But not taxable and not reportable are two different things. The IRS requires US recipients of large foreign gifts to file an information return called Form 3520, and the penalty for missing that filing can be significant even when no tax is owed. This is the part most people do not find out until it is too late.
What Form 3520 is and when you need to file it
Form 3520 is an IRS information return used to report certain foreign gifts and bequests. It is not an income tax return and it does not create a tax liability on its own. Its purpose is to give the IRS visibility into large transfers from foreign persons to US residents, and filing it is a legal requirement once the reporting thresholds are met.
The thresholds depend on who the gift is from:
- For gifts or bequests from a non-resident alien or foreign estate, the reporting threshold is more than $100,000 in a taxable year, aggregated across related parties. Once that threshold is crossed, each individual gift over $5,000 must be separately identified on the form.
- For gifts from foreign corporations or foreign partnerships, the threshold is significantly lower and is adjusted each year. For 2025 the threshold is $20,116 and for 2026 it is $20,573. The IRS scrutinizes gifts from foreign entities more closely because they can be used to disguise income or business payments as gifts.
Form 3520 is filed separately from your regular tax return. It is not attached to your 1040 and it is not e-filed. It is mailed directly to the IRS address specified in the form instructions.
The filing deadline
For most calendar-year filers, Form 3520 is due on April 15, the same day as the regular tax return. US taxpayers living abroad generally have until the 15th day of the sixth month. Filing an extension on Form 4868 extends the Form 3520 deadline to October 15, but no further.
Under this regime, when you sell a PFIC or receive a large distribution from one, the gain or excess distribution is allocated across your entire holding period. The portions allocated to prior years are not taxed as capital gains. Instead, they are taxed at the highest ordinary income rate that applied in each of those prior years, plus an interest charge under Section 1291(c) that compounds on top of the tax itself.
The separate filing requirement is one of the reasons people miss this deadline. Many taxpayers hand their documents to a tax preparer assuming everything will be handled together, without realizing that Form 3520 requires separate handling and a separate mailing. Telling your preparer about a foreign gift at the time it is received, rather than waiting until tax season, is the simplest way to make sure the deadline is not missed.
The penalty for not filing
The penalty for failing to file Form 3520 when required is generally 5% of the value of the gift per month, up to a maximum of 25%. On a $200,000 foreign gift, the maximum penalty is $50,000. The penalty applies even when no income tax is owed on the gift itself.
Reasonable cause can excuse the penalty if it is properly documented and argued, but reasonable cause is not automatic. The burden is on the taxpayer to demonstrate that the failure to file was not due to willful neglect. A general lack of awareness that Form 3520 existed is sometimes accepted as reasonable cause, but it is not guaranteed and the outcome depends on the specific facts.
The IRS has several ways of discovering unreported foreign gifts, including FBAR filings, bank records, and information shared by foreign governments under FATCA. The assumption that a cash gift is undetectable is not a reliable basis for deciding not to file.
Gifts versus inheritances
A bequest received from a foreign estate after the donor’s death is treated similarly to a gift for Form 3520 purposes. Both use the $100,000 threshold for foreign individuals and estates, and the US recipient generally does not owe US income tax on either.
The main exception is when the transfer comes from a covered expatriate, meaning a former US citizen or long-term resident who renounced citizenship or residency and met certain wealth or tax compliance criteria at the time of expatriation. In those cases, IRC Section 2801 may impose a transfer tax on the US recipient at the highest applicable gift or estate tax rate. If you believe the donor may be a covered expatriate, professional advice before receiving the transfer is worth the investment.
When the gift is property rather than cash
If the gift is foreign real estate, foreign stocks, or other assets rather than cash, the US generally does not tax the receipt itself. But the type of property matters significantly for what happens later.
Gifted assets generally carry over the donor’s original cost basis for US tax purposes. When you eventually sell the property, your taxable gain is calculated from that basis, not from the value of the property at the time you received it. If the donor bought property decades ago at a low price, your gain when you sell could be substantial even if the property has not appreciated much since you received it.
Documenting the donor’s original cost basis at the time of the gift is important and frequently overlooked. Once the donor is no longer available to provide that information, reconstructing it can be difficult.
If the gift is deposited into or held in a foreign account, FBAR and Form 8938 reporting obligations may also be triggered separately from the Form 3520 requirement.
What the donor’s home country taxes do not change
If the donor paid gift tax in their home country, that does not eliminate your US Form 3520 reporting obligation. The US recipient generally cannot use a foreign gift tax credit to offset US reporting duties because the issue is reporting, not US income tax on the gift itself.
Tax treaties generally do not override the US reporting requirement for ordinary foreign gifts in the way many people assume. The safest approach is to treat a foreign gift as non-taxable but potentially reportable, and to verify the filing requirement before concluding that nothing needs to be done.
What to do when a large foreign gift arrives
The most important step is documentation at the time of receipt. Keep the donor’s name, relationship to you, country of residence, date of the transfer, form of the transfer (cash, property, or other assets), and the amount or value. If there is any documentation showing that the transfer was a gift rather than compensation, a loan repayment, or a business payment, keep that as well.
Notify your tax preparer as soon as the gift arrives rather than waiting until the following spring. The Form 3520 deadline is separate from the regular return, and giving your preparer adequate lead time is the simplest way to avoid a late filing.
Common mistakes
- Assuming that not taxable means no reporting required is the most common and most expensive mistake in this area. The Form 3520 penalty is calculated as a percentage of the gift value, which means a large gift creates a large penalty exposure even when the underlying tax liability is zero.
- Missing the Form 3520 deadline because it is separate from the regular return is the second most common mistake. Many taxpayers do not know the form exists until they encounter the penalty.
- Confusing the foreign gift reporting threshold with the US annual gift tax exclusion is another frequent error. The US annual exclusion, which allows US donors to give up to a certain amount per year without gift tax consequences, is a completely separate rule that applies to US donors making gifts, not to US recipients receiving gifts from foreign persons.
- Failing to document the donor’s cost basis for gifted foreign property, and not checking whether the receipt of a foreign gift into a foreign account triggers FBAR or Form 8938 obligations, round out the most common oversights.
Frequently asked questions
Is a gift from my parents living in India taxable in the US? Generally no. A gift from a foreign individual is not included in your US gross income, so you do not owe income tax on the amount received. However, if the total gifts from foreign individuals exceed $100,000 in a year, you are required to report them on Form 3520. Not filing that form when required can result in a penalty of up to 25% of the gift value.
What is the threshold for reporting a foreign gift on Form 3520? For gifts from a non-resident alien or foreign estate, the threshold is more than $100,000 in a calendar year, aggregated across related parties. For gifts from foreign corporations or foreign partnerships, the threshold is lower and adjusted annually; for 2026 it is $20,573.
What happens if I miss the Form 3520 deadline? The IRS can assess a penalty of 5% of the gift value per month, up to a maximum of 25%. On a $200,000 gift, that is up to $50,000. Reasonable cause can sometimes excuse the penalty, but it is not automatic. Filing as soon as possible after discovering the missed obligation, along with a reasonable cause statement, is the recommended approach.
Do I need to report a foreign inheritance on Form 3520? Yes, if it exceeds the reporting threshold. A bequest from a foreign estate is treated similarly to a gift for Form 3520 purposes and uses the same $100,000 threshold. The US recipient generally does not owe income tax on the inheritance, but the reporting obligation still applies.
Does it matter what kind of gift I received: cash, property, or stocks? For the initial reporting obligation, the type of gift does not change the Form 3520 requirement. For future tax purposes, however, the type matters significantly. Gifted property carries over the donor’s original cost basis, which affects your capital gains calculation when you eventually sell. Cash gifts have no ongoing basis tracking requirement.
If my relative paid gift tax in their country, do I still need to file Form 3520? Yes. The donor’s payment of gift tax in their home country does not eliminate your US reporting obligation. Form 3520 is an information return, not an income tax return, and the foreign tax paid by the donor does not offset your filing requirement.
What if the gift was deposited into a foreign bank account? If you receive the gift into a foreign bank account, you may have additional reporting obligations beyond Form 3520. If the account balance exceeds $10,000 at any point during the year, FBAR filing on FinCEN Form 114 is required. If your total foreign financial assets exceed the applicable threshold, Form 8938 may also be required.
Foreign gifts and inheritances sit at the intersection of US tax law and international transfers in a way that is easy to mishandle and expensive to get wrong. Every situation is different, and the right approach depends on the source of the gift, its form, and your overall tax picture.
