Cross-border families often assume that gifting assets to children is a simple and tax-efficient way to transfer wealth. In many countries, this may be true. However, when U.S. real estate is involved—and the owner is a non-U.S. person—the rules change dramatically. A transaction that feels like a routine family decision can trigger a substantial and immediate U.S. tax liability if not properly planned.
This issue commonly arises when a non-U.S. parent purchases property in the United States—perhaps for investment, education, or future relocation—and later decides to transfer that property to a child. From a legal ownership perspective, this may seem straightforward. From a U.S. tax perspective, it can be one of the most expensive mistakes a family makes.
The United States imposes a federal gift tax on transfers of property where the donor does not receive full value in return. For U.S. citizens and domiciliaries, this system is somewhat forgiving. They benefit from an annual exclusion and, more importantly, a large lifetime gift and estate tax exemption (over $15 million in recent years, and often discussed in planning contexts as roughly $15 million depending on projections and legislative changes).
This means that most U.S. persons can transfer substantial wealth during life without actually paying gift tax—at least under current law.
However, this favorable treatment does not apply to non-U.S. domiciliaries.
For gift and estate tax purposes, the key concept is domicile, not residency for income tax purposes. A person can be a U.S. tax resident under the substantial presence test and still be treated as a non-domiciliary for transfer tax purposes—or vice versa.
Generally, a non-U.S. domiciliary is someone who:
This distinction is critical because it determines the scope of U.S. transfer taxes and the availability of exemptions.
Non-U.S. domiciliaries are subject to U.S. gift tax only on transfers of U.S.-situs assets. Unfortunately, U.S. real estate squarely falls into that category.
Examples of U.S.-situs assets include:
By contrast, many intangible assets (such as shares of stock in U.S. corporations) are generally not subject to U.S. gift tax when transferred by non-U.S. persons. This creates planning opportunities—but real estate does not benefit from this favorable rule.
Here is where the real problem begins.
While U.S. persons enjoy a multi-million-dollar lifetime exemption, non-U.S. domiciliaries do not receive the same benefit for gift tax purposes. In practice, this means:
As a result, if a non-U.S. parent gifts a U.S. property worth $1 million to a child, the majority of that value may be exposed to U.S. gift tax.
U.S. gift tax rates are progressive and can reach up to 40% at the top bracket. For high-value real estate, this is not a theoretical concern—it is a real and immediate cash cost.
Even more importantly, the tax is calculated based on:
Not the purchase price
Not the original investment
Not the mortgage balance
But the current fair market value of the property at the time of the gift.
This often surprises families. A property purchased years ago for $300,000 that is now worth $1.2 million will be taxed based on the $1.2 million value—not the original cost basis.
Consider the following simplified situation:
A non-U.S. parent purchases a condominium in California for a child attending university. Years later, the child graduates, builds a career in the U.S., and the parent decides to formally transfer ownership as a gift.
At that moment:
Because the parent is a non-U.S. domiciliary:
The result? A potential U.S. gift tax liability approaching hundreds of thousands of dollars.
There are several reasons why this issue is so common:
Many individuals are familiar with U.S. income tax residency rules and assume similar logic applies to gift tax. It does not.
In some jurisdictions, gifting property to children is tax-free or lightly taxed. Families assume the same applies in the U.S.
The concept of U.S.-situs property is not intuitive, especially for globally mobile families.
Often, professional advice is sought after the transfer has already occurred—when planning options are limited or nonexistent.
One of the most dangerous aspects of this situation is that once the gift is completed, it is extremely difficult to reverse for tax purposes.
Clients frequently ask:
In most cases, the answer is no. As for the real estate, the vehicle is called "deed," and under a state property law, it is often impossible to negate the deed transaction.
The IRS generally looks at the substance of the transaction at the time it occurred. If a valid gift was made under state law, the tax consequences follow. Attempting to unwind the transaction after the fact is often ineffective and may introduce additional complications.
The key takeaway is not that gifting U.S. real estate is always a bad idea—but that planning must occur before the transfer.
Depending on the family’s goals, several strategies may be considered:
A sale at fair market value can avoid gift tax, though it introduces income tax considerations (such as capital gains). The structure of the transaction matters.
In some cases, holding U.S. real estate through a foreign corporation or other structure may change the tax treatment of a transfer. However, this approach comes with its own complexities, including potential income tax and compliance implications.
Leveraging annual exclusions may help reduce exposure, though this is often insufficient for high-value properties.
Introducing bona fide debt arrangements may alter the value of the taxable gift, but must be carefully documented and respected.
In some cases, it may be more efficient to retain ownership and address transfer planning through estate strategies, depending on the client’s long-term objectives.
Each of these strategies requires careful coordination between U.S. and foreign tax systems, as well as legal considerations in multiple jurisdictions.
It is also important to consider how gift tax planning interacts with U.S. estate tax.
Non-U.S. domiciliaries are subject to U.S. estate tax on U.S.-situs assets, but they benefit from only a very limited estate tax exemption (historically around $60,000). This creates a separate but equally significant exposure at death.
In some cases, families attempt lifetime gifting to reduce estate tax exposure—only to trigger immediate gift tax instead. Balancing these two regimes is a core part of cross-border planning.
A U.S. gift tax analysis should never be done in isolation. Other factors often include:
What appears to be a simple family decision can quickly become a multi-jurisdictional tax issue.
For non-U.S. individuals owning U.S. real estate, the following principles are critical:
Cross-border families operate in a complex environment where assumptions can be costly. The U.S. transfer tax system is particularly unforgiving when it comes to non-U.S. domiciliaries and U.S.-situs assets.
The difference between a well-planned transfer and an unplanned one can be measured in hundreds of thousands—or even millions—of dollars. With proper structuring, many of these issues can be mitigated or avoided entirely. Without it, families may face unexpected tax bills at the worst possible time.
