Canadians who hold U.S. assets can face a major U.S. estate tax trap if they are not domiciled in the United States. Unlike U.S. citizens, who receive a much larger estate tax exemption, non-U.S.-domiciled Canadians may only exclude $60,000 of U.S.-situs assets from U.S. estate tax when they die.
This issue can affect Canadians who have built wealth and invested in U.S. stocks, U.S. real estate, U.S. bonds, tangible property located in the United States, or other U.S.-situs assets. Without planning, a substantial portion of those assets may be exposed to progressive U.S. estate tax rates that can reach 40%.
What Counts as U.S.-Situs Assets
A Canadian who is not domiciled in the United States can still be subject to U.S. estate tax on assets considered located in the U.S. for estate tax purposes.
Examples include:
- U.S. real estate
- U.S. stocks
- Tangible property located in the United States
- Certain U.S. bonds in some cases
- Potentially membership interests in U.S. LLCs, depending on IRS interpretation
The treatment of U.S. LLC membership interests remains a gray area because Congress has not fully clarified the rules. This makes planning especially important for Canadians who hold U.S. investments through entity structures.
The $60,000 Exemption Problem
The core issue is the very low exemption for non-U.S.-domiciled foreign persons.
If a Canadian owns $1 million in U.S.-situs assets, such as a U.S. stock portfolio and a Florida property, only $60,000 may be excluded from U.S. estate tax.
That leaves $940,000 potentially exposed to U.S. estate tax.
The tax applies at progressive rates, with the top rate reaching 40%. Not all assets are automatically taxed at the top rate, but the impact can still be severe for larger estates.
For Canadians with significant U.S. investments, this can mean that heirs receive far less than expected unless the assets are structured properly before death.
Step One: Confirm U.S. Domicile Status
The first planning question is whether the Canadian individual is actually domiciled in the United States.
Domicile is different from citizenship or temporary presence. It generally looks at whether a person has a long-term intent to remain in the United States.
A Canadian who owns U.S. assets but is not domiciled in the U.S. falls into the non-U.S.-domiciled foreign person category for estate tax purposes.
Once domicile status is confirmed, the next step is to identify the person’s U.S.-situs asset pool and determine the taxable portion.
Planning Strategy 1: Foreign Blocker Corporations
One common way to mitigate or avoid U.S. estate tax exposure is to hold U.S. assets through a foreign blocker corporation.
Possible jurisdictions mentioned include:
- Panama
- Nevis
- Cayman Islands
- British Virgin Islands
- Other Caribbean jurisdictions
A properly structured blocker corporation can prevent the Canadian individual from directly owning U.S.-situs assets at death.
However, the structure must be designed carefully. Not every foreign entity automatically qualifies as a foreign blocker corporation for U.S. tax purposes.
There can also be income tax and capital gains consequences. For example, using a blocker corporation for U.S. real estate may complicate a later sale and create more aggressive withholding obligations.
The key caveat is that estate tax planning should not create a worse result for income tax or capital gains tax. The full structure needs to account for estate tax, income tax, capital gains tax, withholding, and family succession goals.
Planning Strategy 2: Trusts
Trusts can also be used to reduce U.S. estate tax exposure, but they must be drafted and governed correctly.
A trust does not automatically eliminate U.S. estate tax. Only certain types of trusts can avoid estate inclusion, and they must be structured carefully under the U.S. tax code.
The trust must avoid provisions that cause the assets to be pulled back into the taxable estate. Governance mechanisms, control rights, beneficiary terms, and drafting details all matter.
A trust may be useful when the goal is not only tax mitigation, but also making sure children, grandchildren, or future generations are looked after.
Panama Private Interest Foundations
The Panama private interest foundation is mentioned as a useful vehicle in some cases.
It can combine features of a corporation and a trust and may produce favorable tax results when structured properly.
In more advanced planning, a trust can also be combined with an underlying holding company to serve multiple purposes at once.
This type of structure may help with:
- Estate tax mitigation
- Family governance
- Asset continuity
- Holding U.S. investments
- Long-term succession planning
Planning Strategy 3: Gifting
In some cases, gifting may be simpler than using complex structures.
U.S. estate and gift tax rules differ for Canadians who are not domiciled in the United States. This can create planning opportunities if certain assets can be gifted before death.
However, gifts must be coordinated carefully to avoid U.S. gift tax exposure.
The analysis should include:
- Which assets are subject to U.S. gift tax
- Which assets are not subject to U.S. gift tax
- How the assets are being transferred
- Who receives the assets
- Whether the gift creates other tax or reporting consequences
Gifting can be useful where the person is comfortable transferring assets to children or grandchildren during life, but it should not be done casually.
Planning Strategy 4: Treaty Relief
Tax treaties may provide relief in some cases.
The U.S.-Canada tax treaty contains provisions that address estate tax issues for Canadians.
If a Canadian has left Canada and lives elsewhere, other treaties may also matter. Switzerland is mentioned as having one of the strongest estate tax treaties with the United States.
Treaty planning depends on the person’s residence, domicile, asset type, and overall structure.
Combining Estate Planning With Tax Residence Planning
For some Canadians, the broader solution may involve leaving Canada and becoming tax resident in a more tax-friendly jurisdiction.
Panama is mentioned as an example. If a Canadian relocates to Panama and holds properly structured U.S. assets, the overall planning may improve because Panama generally treats foreign-source income favorably.
This can allow a person to address both U.S. estate tax exposure and broader income tax planning.
Main Risks for Canadians With U.S. Assets
The main risk is that Canadians may assume their local accountant, U.S. property tax preparer, or general CPA has addressed the estate tax issue when they have not.
This is especially dangerous for Canadians who own:
- A Florida vacation home
- A Hawaii property
- U.S. brokerage accounts
- U.S. stocks
- U.S. bonds
- U.S. real estate through an entity
- Other U.S.-linked assets
If the estate tax exposure is ignored, heirs may lose a large share of the U.S. asset pool before receiving the inheritance.
Main Takeaway
Canadians who are not domiciled in the United States but hold U.S.-situs assets need estate tax planning before death.
The U.S. exemption may be only $60,000, and the exposed portion of the estate can face progressive tax rates up to 40%.
The practical approach is to identify all U.S.-situs assets, confirm domicile status, value the exposed assets, and then consider structures such as foreign blocker corporations, trusts, Panama private interest foundations, gifting strategies, treaty relief, and, where relevant, relocation to a more tax-friendly jurisdiction.
