Is a Foreign Inheritance Taxable in the US?

If your parent, grandparent, or other relative dies abroad and leaves you money or property, your first question is usually: "Do I owe US tax on this?" The short answer is generally no — the inheritance itself is not taxable income. But the reporting requirements are strict, and the penalty for ignoring them is $10,000 or more.

This post explains exactly when a foreign inheritance triggers US tax, when it does not, and how to file the required paperwork.

The General Rule: No Income Tax on the Inheritance

Under IRC Section 102, gifts and inheritances are excluded from gross income. This applies regardless of where the donor or decedent lived, where the property is located, or how large the inheritance is. A $50,000 inheritance from a German parent and a $5,000,000 inheritance from a Singaporean grandparent are treated the same for income tax purposes: not taxable to the recipient.

This rule is black-letter law. It does not matter whether the decedent was a US citizen, a green-card holder, or a non-resident alien. It does not matter whether the property is cash, real estate, stock, art, or jewelry. The transfer at death is not a taxable event for the recipient under the income tax.

What Is Taxable: Post-Inheritance Income

The inheritance itself is tax-free. But once the assets are yours, they are treated the same as any other assets you own. That means:

• Dividends and interest from inherited stocks or bonds are taxable when received.
• Rental income from inherited real estate is taxable.
• Capital gains when you sell inherited property are taxable (though the basis is generally stepped up to fair market value at death).
• Business income from an inherited company or partnership interest is taxable.

Example: You inherit €300,000 in cash and a rental apartment in Lisbon from your Portuguese father. The €300,000 and the apartment are not taxable income when you receive them. But if the apartment generates €12,000 in annual rent, that €12,000 is taxable on your US return. If you later sell the apartment for a gain above the stepped-up basis, the capital gain is taxable.

The Reporting Requirement: Form 3520

Even though the inheritance is not taxable, you must report it if the total value of gifts and bequests from foreign sources exceeds $100,000 in a calendar year.

Who Must File

Any US person (citizen, resident alien, domestic trust, domestic estate, or domestic partnership) who receives more than $100,000 in aggregate from non-resident aliens or foreign estates during the year.

The $100,000 Threshold

The threshold applies to the aggregate of all gifts and bequests from all foreign non-resident donors. It is not per donor.

When to File

Form 3520 is due with your income tax return, including extensions. If you receive an extension to file your 1040 (such as the automatic June 15 extension for taxpayers abroad), Form 3520 is also due on that date.

The Penalty

Failure to file Form 3520 carries a penalty of $10,000 or 25% of the gift/bequest amount, whichever is greater. The IRS has discretion to abate penalties for reasonable cause, but the starting point is harsh.

Inheritance vs. Gift: Does It Matter?

For Form 3520 purposes, inheritances from foreign estates are treated the same as living gifts from non-resident aliens. The form has separate sections for gifts from non-resident aliens and bequests from foreign estates, but the $100,000 threshold and penalty structure are the same.

The distinction matters more for estate tax:

• The foreign estate may owe estate tax to its home country.
• The US recipient does not owe US estate tax unless the estate is large and includes US situs assets.
• If the decedent was a US citizen or domiciliary, US estate tax applies to the worldwide estate, but that is the estate's obligation, not the beneficiary's.

Documentation Requirements

Good documentation protects you if the IRS questions the transaction. You should keep:

1. The will or intestacy decree — the legal document showing who inherited what.
2. Estate inventory or distribution statement — a list of assets and their values at death.
3. Wire records or bank receipts — proof of the transfer to your account.
4. Appraisals — for real estate, business interests, or valuable personal property.
5. Foreign estate tax returns — if the estate filed any local tax returns.
6. Legal opinion letter — in complex cases, a letter from the foreign attorney confirming the character of the distribution.

The IRS is particularly interested in distinguishing inheritances from disguised income. If you receive $500,000 from a foreign corporation shortly after performing services for that corporation, the IRS may argue it is compensation, not inheritance. Documentation is your defense.

Special Situations

Inherited Foreign Real Estate

If you inherit real estate outside the US, you do not owe US income tax on the inheritance. But you must report it if the total inheritance exceeds $100,000. You should also obtain a local appraisal to establish the stepped-up basis for future capital gains calculations.

If the property generates rental income, you must report it on Schedule E. If you sell the property, the capital gain is calculated using the stepped-up basis (fair market value at decedent's death) minus selling expenses.

Inherited Foreign Stock

Foreign stock inherited from a non-resident alien is not taxable on receipt. The basis is stepped up to fair market value at death. Future dividends are taxable. Future capital gains on sale are taxable.

If the stock is held in a foreign brokerage account, you may also have FBAR and Form 8938 reporting requirements.

Inherited Foreign Retirement Accounts

This is where it gets complicated. If you inherit a foreign pension or retirement account, the US tax treatment depends on the account type and whether the US has a tax treaty with the foreign country. Some foreign pensions are treated as foreign trusts, requiring Form 3520-A and Form 3520. Others are treated as inherited IRAs under treaty provisions. The analysis is fact-specific and requires professional review.

Inheritance from a Foreign Trust

If the decedent's assets were held in a foreign trust at death, the distribution to you may be treated as a foreign trust distribution rather than an estate bequest. Foreign trust distributions have their own reporting rules under Form 3520, including potential 35% penalties for undisclosed foreign trusts. If the trust structure is involved, consult an expat tax specialist before filing.

The Estate Tax Angle (For the Estate, Not You)

As the recipient, you generally do not pay US estate tax. But the estate itself may have tax obligations:

• If the decedent was a US citizen or domiciliary, the estate files Form 706 and estate tax applies to worldwide assets above the exemption ($13.99 million in 2026).
• If the decedent was a non-resident alien, US estate tax applies only to US situs assets (real estate, tangible personal property, stock of US corporations) above a $60,000 exemption.
• Most foreign countries have their own estate or inheritance taxes. You should coordinate with the foreign executor to understand what was paid abroad.
