U.S.-Situs Property for Canadian Residents: Determining Which Assets May Be Subject to U.S. Estate Tax

In the first article of this series, we discussed why a Canadian resident may become subject to the U.S. estate tax regime despite never having lived in the United States. The next step in any cross-border estate tax analysis is identifying whether the deceased owned property that the United States considers to be situated within its jurisdiction. Surprisingly, this question is often more important than the size of the estate itself. Before considering treaty relief, filing obligations or planning opportunities, an advisor must first determine whether any U.S.-situs assets exist.

What Is U.S.-Situs Property?

For estate tax purposes, the United States generally taxes non-resident, non-citizens only on property having a sufficient connection with the United States. This concept is commonly referred to as ‘U.S.-situs property.’ The analysis focuses on the legal nature of the asset rather than the residence of the owner or the location of the financial institution holding the investment. Consequently, two Canadian residents with identical net worth may have very different U.S. estate tax exposure simply because they own different types of assets.

The Most Common U.S.-Situs Assets

The assets most frequently encountered in practice are U.S. real estate and shares of U.S. corporations. Vacation homes in Arizona, Florida or Hawaii are obvious examples. Less obvious is a portfolio of publicly traded U.S. shares held through a Canadian brokerage account. The fact that the investment account is maintained by a Canadian financial institution does not generally change the character of the underlying shares.

Other categories of property may also require consideration, including tangible personal property physically located in the United States, certain business interests and interests in entities whose classification is not immediately apparent. These situations are often fact-specific and should be reviewed individually.

Assets That Commonly Do Not Create Exposure

Not every investment with U.S. economic exposure is a U.S.-situs asset. A Canadian mutual fund that invests in U.S. companies is generally a Canadian investment vehicle rather than direct ownership of the underlying shares. Similarly, shares of Canadian corporations are generally not transformed into U.S.-situs property merely because those corporations conduct business in the United States or own U.S. investments.

This distinction explains why an investor’s portfolio may require a security-by-security review. Two investments with nearly identical economic performance may produce entirely different estate tax results depending on their legal form.

Common Misconceptions

Several misconceptions arise repeatedly. Investors often assume that purchasing U.S. securities through a Canadian broker avoids U.S. estate tax exposure. Others believe that electronic securities have no physical location and therefore cannot be considered U.S.-situs. Another common misunderstanding is that only real estate creates exposure. In practice, investment portfolios are frequently the largest source of U.S.-situs assets encountered by Canadian executors.

It is equally common for families to assume that all registered accounts are automatically exempt. While certain registered plans receive favourable treatment under various provisions of Canadian and U.S. law, the existence of a registered account should never replace a careful review of the underlying assets to determine if any is considered U.S.-situs assets.

A Practical Example

Consider two Canadian investors, each with a $3 million estate. The first owns Canadian bank shares, Canadian mutual funds and a principal residence in British Columbia. The second has the same Canadian assets but also owns a condominium in Arizona and a portfolio of shares of several U.S. public corporations. Although both estates have identical overall value, only the second estate presents an obvious need for a U.S. estate tax analysis. Whether tax will ultimately be payable is a separate question, but identifying the U.S.-situs assets is the necessary first step.

Practice Points

• Review the legal nature of each investment rather than relying on the account title.
• Do not assume a Canadian brokerage account or a registered account designation changes the situs of the underlying asset.
• Maintain records identifying the type and location of significant assets before an executor needs them.
• Where ownership structures are complex, obtain advice before concluding that an asset is or is not U.S.-situs.

Conclusion

Determining whether property is U.S.-situs is the foundation of every U.S. estate tax analysis involving a Canadian resident. Once the relevant assets have been identified, the discussion can move to the next stage: whether the Canada–U.S. Tax Treaty reduces or eliminates the resulting estate tax exposure, and whether any compliance obligations remain. In practice, many estate tax questions that initially appear complicated become much easier once the asset classification exercise has been completed.
