Own U.S. Assets as a Canadian? Here's What You Must Know Before 2025

With the U.S. estate tax exemption set to change in 2025, many Canadians who own U.S. property or investments could face significant and unexpected tax exposure. What once affected only ultra-high-net-worth families may soon impact a broader range of snowbirds, investors, and professionals with cross-border ties.

If you’re a Canadian with U.S. situs assets like a vacation home in Florida or shares in a U.S. corporation you need to act now to protect your estate and avoid unnecessary tax complications later.

Here’s what’s changing, why it matters, and what you can do about it.

Why This Matters More Than Ever

Under current U.S. tax law, non-residents (including Canadians) with U.S. assets exceeding USD $60,000 at death must file a U.S. estate tax return Form 706-NA. But filing doesn’t always mean paying.

Thanks to the Canada-U.S. Tax Treaty, Canadians can access a portion of the U.S. estate tax exemption. The size of that exemption is based on the value of U.S. assets relative to their total global estate.

But here’s the catch:
Unless U.S. Congress intervenes, the federal estate tax exemption is expected to drop from $13.61 million in 2024 to roughly $6 million in 2025. That means more Canadians will have U.S. estate tax exposure especially those with high-value real estate or cross-border portfolios.

A Quick Example

Let’s say your worldwide estate is valued at $12 million, and $3 million of that is U.S.-based. Under the treaty, you’d get 25% of the U.S. exemption.

  • In 2024: 25% of $13.61M = $3.4M exemption → likely no estate tax.

  • In 2025: 25% of $6M = $1.5M exemption → estate tax owed on $1.5M at rates up to 40%.

That’s a serious liability and one many Canadian families aren’t prepared for.

What Types of U.S. Assets Are Affected?

U.S. estate tax applies to U.S. situs assets, which for Canadians typically include:

  • U.S. real estate (including cottages or rental properties)

  • Shares of U.S. companies even if held through a Canadian broker

  • Tangible personal property located in the U.S.

  • Some U.S.-based ETFs and mutual funds

If the total value of these assets exceeds USD $60,000, the estate is required to file even if no tax is ultimately owed.

What the Canada-U.S. Tax Treaty Offers

Thankfully, the treaty between Canada and the U.S. provides several key protections:

  • Pro-rata unified credit: Based on the ratio of U.S. assets to total global estate

  • Spousal credit: For deferral or reduction of estate tax if assets pass to a surviving spouse

  • Foreign tax credit: Avoids double taxation by applying Canadian estate taxes against U.S. liabilities

But here’s the fine print: To access these treaty benefits, you must disclose your entire global estate not just your U.S. assets.

Common Misconceptions And Why They’re Risky

Many Canadians assume that U.S. estate tax doesn’t apply to them. A few myths that need busting:

“My U.S. assets are under $60,000, so I’m fine.”
True for now. But markets move. And even if you're under the threshold today, appreciating assets can quickly push you into filing territory.

“Only U.S. citizens pay U.S. estate tax.”
False. U.S. estate tax applies to non-resident aliens who own U.S. situs property.

“My Canadian will will override U.S. law.”
It won’t. U.S. tax law applies to U.S.-based assets, regardless of your will’s jurisdiction.

Key Actions for Canadian Investors and Families

With major changes on the horizon, here are a few steps you should consider immediately:

1. Inventory Your U.S. Assets

Real estate, shares, collectibles know what you own, and ensure you can value it accurately with supporting documentation.

 2. Review Ownership Structures

Consider holding U.S. property through Canadian corporations or trusts, which may reduce or eliminate exposure.

 3. Plan for Liquidity

Life insurance is often used to create liquidity to pay potential U.S. estate tax, avoiding forced sales of inherited assets.

 4. Coordinate Your Will Across Borders

Ensure your Canadian estate plan addresses your U.S. holdings. This may require coordination between Canadian and U.S. legal counsel.

 5. Work With a Cross-Border Tax Advisor

An experienced advisor can help you file correctly, reduce tax exposure, and navigate the complexities of international probate and compliance.

This Isn’t Just Tax Planning It’s Legacy Planning

For Canadians with U.S. assets, this isn’t just about minimizing tax it’s about ensuring your legacy passes to your family efficiently, without costly legal delays or surprise tax bills.

With the 2025 exemption changes looming, now is the time to take a hard look at your estate structure and act decisively.
