Reporting a Foreign Inheritance to the IRS

Is a Foreign Inheritance Taxed in the US?

Here is the reassurance first, because most people who land on this page are worried about a tax bill that does not exist. A gift or inheritance you receive from a non-resident foreign person is not income to you under US law. The amount does not go on your Form 1040 as income, and you owe no US income tax on it. If your parent abroad left you $300,000, the $300,000 is yours, and the IRS does not take an income-tax cut of it.

The IRS comes in through reporting. Once the total you receive from one foreign person crosses $100,000 in a calendar year, you have to tell the IRS about it on a form called Form 3520. The form carries no tax. The form is a disclosure, nothing more. The reason this matters is that the penalty for skipping the form is tied to the form, not to any tax owed, which is exactly why so many honest people get caught off guard. The rest of this page walks through when you report, how you report, and the foreign accounts that often arrive alongside the money.

When You Have to Report: The $100,000 Line

You report a foreign gift or inheritance when the total from one foreign source crosses a dollar line in a single calendar year. The line depends on who the money came from.

• From a foreign individual or a foreign estate. More than $100,000 in the year. Most inheritances fall here, from a parent or relative who is not a US citizen or resident.
• From a foreign corporation or foreign partnership. A much lower threshold, about $20,573 for 2026, adjusted for inflation each year.

Two details catch people. First, you add up everything from one source across the whole year. Four wires of $30,000 from the same parent cross the $100,000 line together, even though no single transfer did. Second, gifts from people related to the giver can be counted together with theirs, so money from a parent and a sibling abroad may need to be combined. If you have received money from family abroad and you are near these numbers, it is worth a careful look before you assume you are clear.

How Do I Report a Foreign Inheritance to the IRS?

The question I get most about this is, "How do I report a foreign inheritance to the IRS?" The answer is Form 3520, in the section called Part IV, mailed to the IRS on its own by the due date of your income tax return. A few practical points matter more than the form itself.

• The form is mailed separately. Unlike most tax forms, Form 3520 is not attached to your Form 1040. The form goes to its own IRS address. Filing it with your 1040 does not count as filing it.
• The form is due with your return. The deadline tracks your income tax return, generally April 15, with an October 15 extension if you extend your 1040.
• You report the year you received the money. If the inheritance arrived in installments across two calendar years, you may have a report for each year it crossed the line.

If the money is already sitting in your US bank account, that is fine. Moving the money in is not the issue. The issue is whether the report was made for the year you received it. If it was not, the fix is to file the late form correctly now, which we cover in depth on our Form 3520 foreign-gift penalty page.

The "Foreign Inheritance Tax" Myth

The "foreign inheritance tax" is the single most common confusion, so it is worth being clear. People search for it and assume the US will tax them on what they inherited from overseas. The US will not. The US does not tax a US heir on a worldwide inheritance. Your inheritance from a foreign relative is not US income to you, full stop.

A US estate tax exists, but it works in the opposite direction from what people fear. The estate tax falls on the deceased person's estate, not on the heir, and for a non-resident foreign person it reaches only their US-based assets. A non-resident foreign decedent gets just a $60,000 US estate-tax exemption, and the tax above that is graduated, reaching 40%. So if your foreign parent owned a US condo or shares in a US company, their estate may face US estate tax on those US assets before anything reaches you. But if they owned only foreign property, there is no US estate tax at all, and there is still no US income tax on you. The estate-tax side, when a foreign person dies owning US property, is its own topic, covered in our guide to US estate tax for non-resident aliens and our broader guide for non-US citizens. Your part as the heir, in almost every case, is simply the Form 3520 report.

The Foreign Accounts That Come With It

For many people, the inheritance is the easy part and the accounts are the part nobody flagged. A foreign inheritance often arrives as control of, or title to, foreign bank, brokerage, or pension accounts, and that can trigger reporting duties of its own.

• FBAR (FinCEN Form 114). Required if your foreign financial accounts together exceed $10,000 at any point in the year. The test is an aggregate, at-any-point test, not a year-end balance, so even an account you held briefly can count.
• FATCA (Form 8938). A separate IRS report of foreign financial assets above higher thresholds. You can owe both an FBAR and an 8938 for the same accounts.

Inheriting a foreign account is one of the most common ways people pick up these duties without ever knowing they existed. The first year is the one to get right. If a foreign inheritance has just brought foreign accounts into your life, our FBAR and FATCA overview maps how the forms fit together, and the FBAR penalties page covers what to do if you are already behind.

For Americans With Family Abroad and Olim

Americans whose parents or relatives live abroad meet this constantly, including the many who have made aliyah to Israel. A parent in Israel dies, a US-citizen child inherits, and the money wires in from an Israeli estate or bank with no US tax form attached. The foreign lawyer settling the estate handles the foreign side and rarely says a word about US reporting, so the US heir has no reason to suspect a form is due.

Two reassurances and one task. First, you owe no US income tax on the inheritance. Second, there is no US-Israel estate tax treaty, but that does not change your answer, because the US is not taxing you on the inheritance in the first place. The task is the report. If the inheritance crossed $100,000 in a year, you file Form 3520, and if it came with Israeli bank, pension, or investment accounts you now hold, the FBAR and possibly Form 8938 come into play too. We do this regularly for Americans in Israel. See the American-in-Israel paperwork guide and our estate planning for olim page for the wider picture.

What If You Missed the Report?

Many people only learn about Form 3520 years after the money arrived, often when an accountant finally asks the right question. If that is you, the situation is fixable, but the answer is to come forward, not to wait it out. Two things happen when the report is skipped. First, the IRS clock that normally closes an old tax year never starts, so the year stays open until the form is filed. Time does not heal this, and only filing does. Second, a separate penalty can apply to the unreported gift, calculated as a percentage of it, up to 25%.

The good news is real. As of late 2024, the IRS reviews reasonable cause before it charges this penalty, rather than charging first and making you fight to undo it, and innocent, well-documented late filings are often resolved without any penalty. The one move to avoid is quietly mailing in an old form with no explanation, which the IRS treats as a red flag and which forfeits the protection a proper reasonable-cause filing gives you. The full mechanics, the penalty math, and how reasonable cause works live on our Form 3520 foreign-gift penalty page.

How We Work, and When We Co-Counsel

Cross-border reporting covers a wide range, so we are honest about where our role sits. A straightforward foreign gift or inheritance, screening the facts, preparing the current or late Form 3520, and sorting out the FBAR for any inherited accounts, is handled here, on a fee quoted up front once we see your situation. For ongoing foreign trusts, layered offshore structures, and large multi-year cleanups that also involve unreported foreign income, we co-counsel with an international tax advisor so you get the right depth without paying for the wrong tool.

Almost all of this is done by phone and video, which fits clients who are out of state or out of the country. If a foreign inheritance is bringing US reporting into your life for the first time, the pieces tend to come in layers, and our international and cross-border hub maps how the Form 3520, FBAR, FATCA, and trust forms fit together.

Frequently Asked Questions

Common Situations

The wire from an Israeli estate. A US citizen in Florida inherits about $350,000 from a parent in Israel. The money arrives over a few months, no tax form attached, and a year later her accountant asks whether she received anything from abroad. Because the inheritance was over $100,000, Form 3520 was due. She owes no income tax on it; the task is the report, filed for the year she received the money.

The inheritance that came with an account. A son inherits roughly $80,000 in cash, below the Form 3520 line, but also takes over his late father's foreign brokerage account holding $200,000. The cash needs no Form 3520, but the foreign account puts him over the $10,000 FBAR line and likely Form 8938 too. The account, not the cash, is the reporting event.

The "do I owe foreign inheritance tax?" worry. A client is convinced the US will tax a six-figure inheritance from a foreign parent and is bracing for a huge bill. No US income tax applies to the inheritance and, because the parent owned only foreign property, no US estate tax either. The entire obligation turns out to be one information form.

What One Foreign-Gift Penalty Case Shows About Timing

In my practice the same problem shows up over and over, and it is almost never the one people call about. People call me about the tax, and there is no tax. The problem is a form that carries no tax and a penalty that does not care whether any tax was owed.

The calls I take about this almost always come a year or two after the money arrived, when an accountant finally asks whether anything came from abroad. A 2025 decision from a federal court in California shows what that delay costs, and I read it in full. A woman received gifts from her parents overseas in 2015 and 2016 so that she could move to the United States for good and buy a house. She did her own returns with TurboTax, and the software told her that a person who receives money reports nothing, because the giver does the reporting (which is the rule for an American giver, and the wrong rule for a foreign one). In April 2018 she learned that Form 3520 existed and filed both years within days. The IRS assessed the penalties automatically, $62,496.25 for 2015 and $28,742.50 for 2016, which at the 25 percent cap means gifts of roughly $250,000 and $115,000. She wrote a reasonable-cause letter, and the IRS denied it in September 2019. She appealed, and during the appeal the agency’s figure grew to more than $153,000, close to $190,000 with interest, because the 2015 penalty had been entered twice. In August 2023 the Appeals office removed $117,243.25 and kept $36,495.50. She paid that with interest in February 2024, filed for a refund, and sued when six months passed with no answer. In May 2025 the court let her reasonable-cause claim go forward and dismissed everything else, and by then the IRS had mailed her a $13,018.90 refund check that its own lawyers told her not to cash. Ten years after the first gift, nobody has decided whether she owed a dollar.

In reading that file against the calls I take, I have a few take-home points.

The first is the software. The answer she got is correct for an American giver and wrong for a foreign one, and the program never asked where her parents lived. The practice pointer I take from it is that the question which decides this form is the giver’s residence and not the size of the wire, so I ask it on every intake, because a preparer who skips it files a clean return with a $62,496.25 problem behind it.

Second, the penalty in that case was assessed by a machine before anyone read her letter, and the figure was wrong by $62,500 for nearly four years. Since October 2024 the IRS says it reads the reasonable-cause statement before it assesses, which is the better order, and the way I use it is to attach the statement to the late form itself. Avoid mailing a late Form 3520 with nothing attached, because a form that arrives alone goes into the automatic process, and her 2018 filing is what that process produced.

Third, I recompute every penalty notice before I answer it. The Taxpayer Advocate counted more than $179 million a year in these penalties abated from 2018 through 2021, roughly two thirds of what was charged, which tells you how often the first figure is wrong. The practice pointer is to work the penalty from the gift amount, the due date, and the months late, because the notice in that case carried the same year twice and the taxpayer was the one who found it.

Lastly, look at what the missing form cost. Two Forms 3520, filed by April 2016 and April 2017, would have reported the gifts and cost her nothing, because the form carries no tax. Filed late with a reasonable-cause statement attached, the same two forms would have put her explanation in front of a person before any number existed. What she paid instead was $36,495.50 plus interest, seven years of letters, appeals and a lawsuit, and a question that is still open. The screen that decides which of those filings a family needs, and drafts the statement, is a flat fee quoted at the consult, and the consult is free.

What that decision cannot tell you is whether relying on tax software is reasonable cause. The court held only that she had said enough to keep the claim alive, and a court in the same district rejected the same argument on a full record in 2018. Whether a program’s advice counts the way a professional’s does is unsettled, and I will say so at the consult rather than promise it.
