US Estate Tax and Real Estate Investment: The $60,000 Exemption Wall for Nonresident Aliens, and How to Plan Around It

/ Blog (EN), Real Estate & Rental Income / By

For Japanese residents who own U.S. rental property or a vacation home, income tax on rent and gains is well understood, but one thing that’s often overlooked is U.S. estate tax exposure if the owner passes away. The rules and exemption amounts differ dramatically from Japan’s inheritance tax, and without planning ahead, the tax bill can be substantial. This article covers estate tax risk for nonresident aliens holding U.S. real estate, and the main planning strategies. We cover the basics of U.S. estate tax generally in a separate article; here we focus on issues specific to U.S. real estate investors.

The Nonresident Exemption Is Only $60,000

When a U.S. citizen or a person domiciled in the U.S. dies, a $15 million exemption applies (as of 2026, made permanent by the One Big Beautiful Bill Act and indexed for inflation going forward). But for a nonresident alien — someone like a Japanese resident who is neither a U.S. citizen nor domiciled in the U.S. — the exemption for U.S.-situs assets is only $60,000. Real estate located in the U.S. generally counts as a U.S.-situs asset, so anything above that exemption is taxed at graduated rates up to 40%. For anyone holding real estate worth hundreds of thousands or millions of dollars, this tiny exemption is a serious risk.

Possible Relief Under the US-Japan Estate Tax Treaty

The U.S. and Japan have long had a tax treaty covering estate and gift taxes, under which certain taxpayers can qualify for a more favorable “prorated unified credit” than the plain $60,000 exemption. Under this approach, the full exemption a U.S. citizen or resident would receive is prorated based on the ratio of U.S.-situs assets to the decedent’s worldwide estate, and that prorated amount can be used as your exemption. The smaller the share of U.S. real estate is within your total worldwide estate, the more favorable this treatment becomes. That said, the requirements and calculations for treaty application are complex, and always require individualized professional review.

The Filing Requirement: Form 706-NA

If a nonresident alien’s U.S.-situs assets exceed the exemption (generally $60,000, or the prorated treaty amount if applicable), the heirs must file Form 706-NA (United States Estate Tax Return, Estate of Nonresident Not a Citizen of the United States), generally within 9 months of the date of death (a 6-month extension is available via Form 4768). Failing to file and pay can effectively freeze re-titling or sale of U.S. assets, including real estate, so prompt action is needed even if the heirs are based in Japan.

A Common Planning Strategy: Using a Blocker Corporation

Instead of holding U.S. real estate directly in your own name, holding it indirectly through a corporation formed outside the U.S. (for example, in Japan or a third country) — a so-called “blocker corporation” — is a widely used estate tax planning technique. Under U.S. estate tax rules, shares of a foreign corporation generally do not count as U.S.-situs property, even if that corporation itself owns U.S. real estate. The logic is that what’s inherited is “shares of a foreign corporation,” not the U.S. real estate itself, so it falls outside the scope of U.S. estate tax.

This approach comes with tradeoffs, though. When a foreign corporation owns and sells U.S. real estate, the corporation itself can become subject to U.S. corporate tax, FIRPTA withholding, and potentially an additional tax similar to the Branch Profits Tax — so while estate tax may be avoided, the tax burden during ownership and at sale can end up higher than if you’d held the property personally. The structure needs to be designed with a tax professional, taking into account your expected holding period, plans for a future sale, and how the U.S. property fits into your overall estate.

Another Option: Life Insurance

Life insurance proceeds payable to a nonresident alien generally don’t count as U.S.-situs assets, so they fall outside the scope of U.S. estate tax. A common practical strategy is to estimate your potential U.S. estate tax liability in advance and hold enough life insurance (including non-U.S. policies) to cover it, ensuring your heirs have the funds available to pay the tax when the time comes.

Frequently Asked Questions

Q: Does this apply to a vacation home I use myself and don’t rent out?

A: Yes. Whether a property is rented out or used personally makes no difference to whether it counts as a U.S.-situs asset for estate tax purposes. A vacation home in Hawaii or California is treated the same way as a rental property.

Q: Does holding the property through a U.S. LLC avoid estate tax?

A: No. A single-member U.S. LLC treated as a disregarded entity is treated, for estate tax purposes, the same as owning the real estate directly, so it does not avoid estate tax. Only holding the property through a corporation formed outside the U.S. provides this kind of protection.

Eligibility for the US-Japan treaty and the best structure for a blocker corporation depend on individual circumstances, so please consult a professional based on your specific holdings.

Summary

U.S. real estate investors tend to focus on income and capital gains tax, but the fact that a nonresident alien’s U.S. estate tax exemption is only $60,000 becomes a serious risk as your holdings grow. Weigh options including the US-Japan treaty’s prorated credit, a blocker corporation structure, and life insurance to fund the eventual tax bill, and start planning well in advance.
