Snowbird with $2M in U.S. Property: Canadian Estate Tax Exposure Most Cross-Border Owners Miss

The $60,000 Exemption That Surprises Every Snowbird

The U.S. estate tax applies to the worldwide assets of U.S. citizens and residents, with a generous exemption of $13.61 million USD in 2026. But for non-resident aliens — which includes every Canadian citizen who is not also a U.S. citizen or green card holder — the rules are fundamentally different.

Under Internal Revenue Code sections 2101 to 2108, non-resident aliens are subject to U.S. estate tax only on their U.S. situs assets. The default exemption for non-resident aliens is just $60,000 USD. That is not a typo. The exemption that protects $13.61 million for a U.S. citizen protects only $60,000 for a Canadian snowbird.

U.S. estate tax rates are graduated from 18% to 40%, with the top rate applying to taxable estates above $1 million USD. On a Florida condo worth $800,000 USD with only the $60,000 exemption, the U.S. estate tax would be approximately $245,000 USD.

What Counts as a U.S. Situs Asset

The IRS defines U.S. situs assets under IRC sections 2104 and 2105. For Canadian snowbirds, the most common categories are:

• U.S. real estate — vacation condos, rental properties, undeveloped land, and timeshares located anywhere in the United States
• Shares of U.S. corporations held directly — this includes Apple, Amazon, Microsoft, Tesla, and every other company incorporated in a U.S. state, whether held in a taxable account, a Canadian RRSP, or a TFSA
• Tangible personal property in the U.S. — vehicles registered in the U.S., boats moored in U.S. waters, furniture and art in your U.S. home
• U.S. debt obligations — bonds issued by U.S. corporations or governments (with exceptions for certain bank deposits and portfolio interest)

What is not a U.S. situs asset:

• Canadian-domiciled mutual funds and ETFs that hold U.S. stocks — the Canadian fund wrapper means you own units of a Canadian trust, not direct shares of U.S. companies
• U.S. bank deposits — cash in a U.S. bank account used for personal purposes (not connected to a U.S. business) is generally exempt under IRC section 2105(b)
• Life insurance proceeds on the life of a non-resident alien — exempt under IRC section 2105(a)

How the Canada-U.S. Tax Treaty Fixes Part of the Problem

Article XXIX-B of the Canada-U.S. Tax Treaty provides a prorated unified credit that dramatically increases the effective exemption for Canadian residents. The formula works like this:

The treaty also provides a marital credit for property passing to a surviving spouse, effectively allowing deferral of estate tax on the spousal share — similar to the unlimited marital deduction available to U.S. citizens, though mechanically different.

When the Treaty Credit Falls Short

The prorated credit works well when U.S. situs assets are a small proportion of the worldwide estate. It starts to break down in two scenarios:

1. High concentration of U.S. situs assets. If U.S. situs assets represent 60-70% or more of the worldwide estate, the prorated exemption shrinks proportionally and may not cover the full U.S. exposure. A Canadian with a $2 million USD worldwide estate where $1.4 million is U.S. situs gets a prorated exemption of $13.61M × ($1.4M / $2M) = $9.53M — still enough. But the ratio matters as worldwide estates grow.
2. Worldwide estates approaching or exceeding $13.61 million USD. Once the worldwide estate exceeds the U.S. exemption threshold, the prorated credit can no longer eliminate the tax entirely. A Canadian with a $20 million USD worldwide estate and $2 million in U.S. situs assets gets a prorated exemption of $13.61M × ($2M / $20M) = $1.36M — leaving $640,000 of U.S. assets exposed to U.S. estate tax at rates up to 40%.

Vacation Property vs. Rental Property: Same Estate Tax, Different Income Tax

For U.S. estate tax purposes, a vacation condo in Naples and a rental condo in Phoenix are treated identically — both are U.S. real property and U.S. situs assets. The estate tax exposure is the same.

The difference is in the income tax treatment during ownership and on sale:

U.S. Vacation Property (Personal Use)

• No U.S. rental income to report
• No annual U.S. income tax filing obligation (unless rented for 15+ days per year)
• On sale, FIRPTA withholding of 15% of gross sale price applies — the Canadian seller files a U.S. non-resident tax return (Form 1040-NR) to report the capital gain and claim a refund of excess withholding
• The IRC section 121 principal residence exclusion ($250,000/$500,000 gain exclusion for a primary home) does not apply to a vacation home
• In Canada, the property is reported on the deemed disposition at death, and any gain is taxable at Canadian capital gains inclusion rates

U.S. Rental Property

• Annual U.S. income tax filing required — the Canadian owner should file Form 1040-NR and elect under IRC section 871(d) to treat the rental income as "effectively connected income," allowing deductions for expenses, depreciation, and mortgage interest
• Without the section 871(d) election, gross rental income is taxed at a flat 30% with no deductions
• FIRPTA withholding on sale (15% of gross price) and capital gains reporting on Form 1040-NR
• Depreciation recapture on sale at up to 25% for U.S. tax purposes
• In Canada, rental income must be reported and Canadian tax is owing — a foreign tax credit for U.S. taxes paid can be claimed to reduce double taxation

The bottom line: both property types create the same U.S. estate tax exposure at death, but rental property has significantly higher compliance costs during ownership. For more on how capital gains work when property is inherited, see our guide to capital gains on inherited property.

What Happens When a Canadian Dies With a U.S. Brokerage Account

Many Canadian snowbirds open a U.S. brokerage account to hold U.S.-listed stocks, either for convenience or to avoid currency conversion fees. At death, this creates a dual-jurisdiction problem that most families are unprepared for.

The U.S. Side

Every directly held share of a U.S. corporation in the brokerage account is a U.S. situs asset. If the account holds $400,000 in Apple, Amazon, and Johnson & Johnson, the full $400,000 is included in the U.S. estate. The brokerage firm will freeze the account upon learning of the owner's death and require one of the following before releasing assets:

• An IRS estate tax closing letter (Form 706-NA filed and accepted)
• A transfer certificate issued by the IRS
• A Small Estate Affidavit (for estates under the filing threshold after treaty credits)

This process routinely takes 6 to 18 months. During that time, the surviving family cannot sell, transfer, or access the funds in the U.S. account.

The Canadian Side

Under subsection 70(5) of the Income Tax Act, the deceased is deemed to have sold all assets at fair market value immediately before death. The capital gains on the U.S. stocks are reported on the Canadian final return, with the gain calculated in Canadian dollars using the exchange rate at the date of death.

If U.S. estate tax is also owing on the same shares, the Canada-U.S. Tax Treaty provides a foreign tax credit mechanism under Article XXIV. The Canadian return can claim a credit for U.S. estate tax paid that is attributable to the capital gain — but the credit is limited to the Canadian tax otherwise payable on that income. If the U.S. estate tax exceeds the Canadian income tax on the same gain, the excess is not fully recoverable.

Joint Ownership: The Strategy That Backfires in Both Countries

Canadian snowbirds frequently add a spouse or adult child to the title of their U.S. property as joint tenants with right of survivorship (JTWROS), assuming this avoids estate tax and probate. It does neither — and creates new problems in both countries.

U.S. Treatment of Joint Ownership

Under IRC section 2040, when joint owners are not spouses, the IRS presumes the full value of the property is included in the estate of the first owner to die — unless the surviving owner can prove they made an independent financial contribution to the purchase. If a parent bought the $800,000 Florida condo alone and later added an adult child to the title, the full $800,000 is included in the parent's estate for U.S. estate tax purposes.

For spousal joint ownership, the rules are slightly better: only 50% of the property is included in the estate of the first spouse to die, regardless of who paid. But the surviving spouse's 50% is then included in their estate at their death — there is no step-up in basis for the surviving non-U.S.-citizen spouse on the deceased's share unless the marital credit is properly claimed.

Canadian Treatment of Joint Ownership

Adding a child to the title of a property is a disposition under Canadian tax law. The parent is deemed to have transferred a portion of the property at fair market value, which can trigger an immediate capital gains tax liability. If the condo was purchased for $300,000 USD and is now worth $800,000 USD, adding a child to a 50% interest means the parent has disposed of a $400,000 interest for proceeds of $400,000, with an adjusted cost base of $150,000 — a $250,000 USD capital gain, reported in Canadian dollars.

Joint ownership also exposes the property to the child's creditors, potential family law claims if the child divorces, and creates complications if the child predeceases the parent. For more on how joint ownership structures work, see our guide to joint tenancy vs. tenants in common.

Restructuring Options: Holding Companies and Cross-Border Trusts

For Canadian snowbirds with significant U.S. real estate exposure, two restructuring strategies are commonly discussed. Both have trade-offs.

Option 1: Canadian Holding Company

Transferring U.S. real estate into a Canadian corporation removes the property from the individual's U.S. estate — the individual now owns shares of a Canadian corporation, which is not a U.S. situs asset. However, the trade-offs are substantial:

• Branch profits tax: Rental income earned by a Canadian corporation on U.S. property is subject to U.S. corporate tax (21%) plus a branch profits tax of 5% under the treaty (30% without the treaty)
• No personal use benefit: If the shareholder uses the property personally, CRA may assess a shareholder benefit under subsection 15(1) of the Income Tax Act
• FIRPTA on sale: 15% withholding on the gross sale price, plus U.S. corporate capital gains tax
• Annual compliance: U.S. Form 1120-F, state corporate returns, Canadian corporate returns, and potential transfer pricing documentation
• Transfer costs: Moving an existing property into a corporation triggers a disposition at fair market value, creating capital gains tax and potential land transfer taxes

The corporate structure makes economic sense primarily for higher-value rental properties where the estate tax savings exceed the ongoing compliance costs — typically properties worth $1.5 million USD or more with meaningful rental income. For a personal vacation home worth $500,000-$800,000, the annual costs usually outweigh the estate tax benefit, especially after treaty credits. For more on holding company strategies, see our guide to holding company tax planning.

Option 2: Cross-Border Trust

A properly structured cross-border trust can remove U.S. property from the Canadian individual's estate while preserving personal use. The trust must be carefully designed to be treated as a "foreign non-grantor trust" for U.S. purposes (so the property is not included in the settlor's estate) while complying with Canadian trust reporting rules including the T3 return and the expanded trust reporting requirements introduced in 2024.

Trust structures involve significant legal fees ($15,000-$40,000+ to establish) and ongoing annual costs ($3,000-$8,000+ for dual-jurisdiction compliance). They are most appropriate for U.S. properties worth $2 million USD or more, or for families with complex succession objectives — such as ensuring the property passes to specific beneficiaries across multiple generations.

Worked Example: A $3.5M Estate With $1.2M in U.S. Situs Assets

David and Karen are married Canadians living in Mississauga. David is 72. Their estate includes:

Converting to USD at an assumed rate of 1.37 CAD/USD: worldwide estate is approximately $2.59 million USD, and U.S. situs assets are approximately $1.20 million USD.

Scenario 1: No Treaty Election Filed

If Karen (as executor) does not file IRS Form 706-NA, the default $60,000 exemption applies. U.S. estate tax on $1.20 million USD with a $60,000 exemption would be approximately $390,000 USD ($534,000 CAD). The U.S. brokerage account is frozen for 12+ months.

Scenario 2: Treaty Election Filed Properly

Karen files Form 706-NA within nine months and elects the treaty benefit. The prorated exemption is $13.61M × ($1.20M / $2.59M) = $6.31 million USD. Since U.S. situs assets ($1.20M) are far below the prorated exemption ($6.31M), no U.S. estate tax is owing. Additionally, the marital credit provides further protection for assets passing to Karen as the surviving spouse.

Canadian Tax on the Same Estate

Regardless of U.S. estate tax, David's death triggers Canadian deemed disposition on all assets. The RRSP rolls over to Karen tax-free under subsection 70(6) of the Income Tax Act. The principal residence exemption covers the Mississauga home. But the Florida condo and the U.S. brokerage account are both subject to deemed disposition.

If the Florida condo was purchased for $400,000 CAD and is now worth $1,100,000 CAD, the capital gain is $700,000. Under the 2026 capital gains inclusion rates, the taxable portion on gains above $250,000 is included at two-thirds, creating a significant Canadian tax liability on the final return. For more on how deemed disposition works at death, see our guide to deemed disposition and capital gains at death.

If U.S. estate tax had also been paid (in the no-treaty scenario), the Canadian return could claim a foreign tax credit — but only up to the Canadian tax otherwise payable on the same income. The mismatch between the U.S. estate tax (based on fair market value of the asset) and the Canadian income tax (based on the capital gain) means the credit rarely provides a perfect offset.

What Canadian Snowbirds Should Do Now

The cost of inaction is not theoretical — it is a specific dollar amount that can be calculated for your estate today. Here is the priority list:

1. Inventory your U.S. situs assets. List every U.S. property, every directly held U.S. stock, every U.S. brokerage account. Convert values to USD. This is the number the IRS cares about.
2. Calculate your treaty protection. Run the prorated exemption formula: $13.61M × (U.S. situs assets / worldwide estate). If the result exceeds your U.S. situs assets, you are protected — but only if the form is filed.
3. Ensure your executor knows about Form 706-NA. This is the single most important cross-border estate planning step. Write it into your will's executor instructions. Brief your executor and your accountant now, not after death.
4. Move directly held U.S. stocks into Canadian-domiciled ETFs. This eliminates U.S. estate tax exposure on your equity portfolio without changing your investment thesis. The cost is a one-time capital gains event on the disposition.
5. Evaluate corporate or trust structures for high-value U.S. real estate. If your U.S. property is worth $1.5 million USD or more and you have rental income, the compliance costs of a holding company may be justified. Get advice from a cross-border tax specialist — not a general accountant.
6. Review joint ownership arrangements. If you added a child to the title of your U.S. property, understand that it may not reduce the U.S. estate tax exposure and it created an immediate Canadian tax event. A trust may be a better structure.
7. Update your will and powers of attorney for both jurisdictions. Your Canadian will should address your U.S. assets, or you may need a separate U.S. situs will for the U.S. property. A cross-border estate lawyer can advise on whether a single will or dual wills is appropriate for your situation. For more on trust vs. will structures, see our guide to trusts vs. wills.
