CANADIAN SNOWBIRD TAX SERIES
By Lucas Wennersten, CFP® (US & Canada), CFA · 12-minute read
First, the honest answer: usually, don’t
Somebody — an accountant, a neighbour in the same complex, a seminar host in Phoenix — tells a Canadian couple that owning their US condo personally is a mistake, and that a corporation or a trust or an LLC will solve the estate tax problem.
For most snowbirds, that advice makes their situation worse rather than better.
It is worth understanding why before understanding the structures, because the reasoning applies to nearly every case. The problem these structures are meant to solve — US estate tax exposure on US-situs property — is usually already solved for free by Article XXIX-B treaty relief. The treaty replaces the US$60,000 nonresident exemption with a proportional share of the full US exemption, and for a Canadian family whose US property is a minority of their net worth, that share ordinarily exceeds the property’s value comfortably. The tax comes out at nil.
So the structure is often solving a problem that no longer exists, while introducing several that did not exist before — some of which recur every single year, and most of which are expensive to reverse.
This post covers what each structure actually does, why two of them are actively dangerous for Canadians, what tends to work instead, and the narrow set of circumstances where structure is genuinely warranted. For where this sits in the wider picture, start with The Canadian Snowbird Tax Guide.
The Canadian holding company, and the rule that ruins it
alt=”Personal ownership versus Canadian corporate ownership of US property showing annual shareholder benefit versus one-time estate exposure” width=”1200″ height=”630″ />
The pitch is simple. Put the condo inside a Canadian corporation. The corporation owns the US-situs asset rather than you, so on your death you own shares of a Canadian company — not US property — and the US estate tax exposure disappears.
The logic holds. The problem is what happens in every year you are alive.
When a corporation owns property that its shareholder uses personally, the Canada Revenue Agency can assess a shareholder benefit. You are enjoying something of value belonging to the corporation, and that enjoyment is treated as a benefit conferred on you as shareholder — taxable in your hands, typically measured by reference to the property’s value or an imputed rent, and assessed annually.
This is not a technicality that careful drafting avoids. It is the central reason corporate ownership of personal-use recreational property is generally unattractive in Canada, and it applies whether the property sits in Muskoka or in Scottsdale.
Weigh the two sides honestly. On one side, a US estate tax that treaty relief usually reduces to zero anyway, arising once, at death. On the other, a Canadian taxable benefit arising every year you use your own condo, for as long as you own it.
There are further costs stacked behind that one. Corporate ownership means the gain on eventual sale is realised inside the company and taxed at corporate rates, then taxed again when the proceeds are extracted. Filing obligations multiply on both sides — a Canadian corporation holding foreign property brings CRA Form T1134 and related reporting into the picture. And a US person among the shareholders or beneficiaries can trigger IRS Form 5471 obligations that are genuinely punishing to miss.
For a family using the property themselves — which describes nearly every snowbird — this structure trades a solved problem for an annual one.
The US LLC: the single most common cross-border mistake
If there is one structure to understand well enough to refuse, it is this one.
A US limited liability company looks ideal to an American adviser. It is cheap, flexible, gives liability protection, and for US tax purposes is generally a flow-through — income passes to the members and is taxed once, in their hands.
The difficulty is that Canada does not see it that way.
The CRA generally treats a US LLC as a corporation, not a flow-through. So the same entity is transparent to one tax authority and opaque to the other. That mismatch is not cosmetic. It breaks the mechanism that normally prevents double taxation.
The foreign tax credit system works by matching income taxed in one country against the same income taxed in the other, in the hands of the same person, in the same year. When the two countries disagree about who earned the income — the member, says the IRS; the company, says the CRA — the credit can fail to line up. Tax is paid in the United States, tax is paid again in Canada, and the relief that should have prevented the second payment does not fully arrive.
Article IV(6) of the Canada-United States Tax Convention provides relief for certain hybrid-entity situations, and it has improved matters. It is not a complete answer, and relying on it requires the position to be claimed and defended correctly.
The practical rule most cross-border advisers apply is blunt: a Canadian resident should not hold US property through an LLC without specific cross-border advice confirming it works in their case. Not “probably fine.” Confirmed.
This matters more than the other structures because of how it typically arises. Nobody sets out to create a hybrid mismatch. A US realtor or title agent suggests an LLC as routine good practice, the buyer agrees because it sounds sensible, and the problem is discovered years later by an accountant reconciling two returns that will not reconcile.
Trusts
Trusts can genuinely work, and they are the structure most likely to be appropriate where structure is appropriate at all. They are also the most expensive to establish and administer, and the most sensitive to being set up incorrectly.
Several considerations tend to dominate:
- US grantor trust rules. Depending on how the trust is structured and who retains what powers, the US may look through it entirely — which can defeat the estate tax purpose while leaving all the cost.
- The Canadian 21-year rule. Canadian trusts face a deemed disposition of their capital property at 21-year intervals, which can generate a substantial tax event on a schedule nobody planned around.
- Loss of control. A trust that solves the estate problem generally has to be one where you have genuinely given the property away. Families frequently want the tax result without the substance, and that combination is the one that fails on audit.
- Administration. Trustee duties, annual filings in two countries, and professional fees that continue for the life of the trust.
Where the US holdings are large, where there are multiple properties, or where succession involves complications beyond a straightforward transfer to a spouse, a properly built trust can earn its cost. For one condo, it very rarely does.
Partnerships and co-ownership
alt=”Comparison of personal ownership, Canadian holdco, US LLC, and trust structures for Canadians holding US real property” width=”1200″ height=”630″ />
Partnership structures are sometimes proposed as a middle path, and there are circumstances — genuine rental operations, multiple unrelated owners — where a partnership is the natural form.
The situs analysis is not as clean as it is often presented. Whether a partnership interest held by a nonresident is US-situs for estate tax purposes depends on facts and is an area where practitioners differ. That uncertainty is itself a reason for caution: a structure adopted specifically to produce a tax result should not rest on a question that reasonable advisers answer differently.
Simple co-ownership between spouses is a different matter and much more common. It has its own consequences — including how each spouse’s contribution to the purchase is treated, and what happens on the first death — and it is worth doing deliberately rather than by default at the closing table. If you are still at the buying stage, our guide to buying a home in Arizona as a Canadian covers the purchase process itself.
What actually works for most snowbirds
The unglamorous answer, which is also usually the right one:
Own it personally. Rely on the treaty. Insure the gap if there is one.
Personal ownership keeps the position simple, keeps the eventual sale in the capital gains system rather than the corporate one, avoids any shareholder benefit question, and avoids the hybrid entity problem entirely. Treaty relief under Article XXIX-B handles the estate tax for the overwhelming majority of Canadian families holding a single US property.
Where a residual exposure genuinely exists — a large US holding, or an estate weighted heavily toward US assets — life insurance is frequently the cleaner answer than restructuring. It funds the liability rather than trying to eliminate it, it is reversible in a way that a corporate structure is not, and it does not create annual tax consequences while you are alive.
The estate is still going to need Form 706-NA filed — the filing threshold is US-situs assets over US$60,000 regardless of tax owing — but that is a paperwork obligation, not a reason to reorganise your ownership.
When structure is genuinely warranted
None of this means structures are never right. They are right in a minority of cases, and those cases share features:
- The treaty pro-ration does not cover the exposure. Estates that are both large and heavily weighted toward US assets can exceed what the proportional credit shelters.
- Multiple US properties, or a genuine rental business. Once the property is an operating asset rather than a personal residence, the shareholder benefit objection largely falls away and the analysis changes completely.
- Real liability exposure. Short-term rental operations carry risk that liability protection meaningfully addresses.
- Succession complexity. Blended families, minor beneficiaries, or a spouse who is a US citizen — that last one changes the analysis substantially and needs its own advice.
- The property is already held in a structure. If you inherited the arrangement or set it up years ago, the question is not whether to build one but whether unwinding it costs more than keeping it.
Notice that most of these describe a property that is an investment rather than a place you spend your winters. That is the real dividing line.
The asymmetry that should decide it
alt=”Decision path for Canadians considering a holding structure for US property, from treaty relief through insurance to structural options” width=”1200″ height=”630″ />
Structures are easy to enter and expensive to leave.
Transferring a property into a corporation or trust is generally a disposition — potentially triggering Canadian capital gains tax on the way in and FIRPTA withholding on the US side. Taking it back out is another disposition, with its own tax, and possibly a shareholder benefit assessment on top.
So a family that restructures and later discovers the structure was unnecessary does not simply return to where they started. They pay to get in, pay to get out, and absorb the annual costs in between.
When one path is reversible and the other is not, the burden of proof belongs on the irreversible one. Personal ownership can be restructured later if circumstances change. A corporation holding a condo cannot be casually undone.
That asymmetry, more than any individual tax rule, is why the default should be to do nothing until a specific reason to act is identified — and why “someone at the club said” is not that reason.
A sequencing checklist before you restructure anything
- Quantify the actual exposure first. Total your US-situs assets and your worldwide estate, and run the treaty pro-ration. Most people discover the exposure is nil.
- If it is nil, stop. There is nothing to solve.
- If there is residual exposure, price insurance against it before pricing a structure. It is usually cheaper and always more reversible.
- Establish how the property is actually used. Personal use, rental, or mixed — this determines whether corporate ownership is viable at all.
- If any US person is involved as owner, spouse, or beneficiary, stop and get specific advice. The analysis changes completely.
- Price the entry cost honestly — the disposition on transfer in, professional fees, and the annual compliance on both sides.
- Price the exit cost too. Ask what unwinding would cost in five years if circumstances change.
- Get the advice in writing, from someone qualified in both countries. A structure recommended by an adviser who only sees one side is the source of most of the damage in this area.
Steps 1 and 2 resolve the majority of cases. Step 7 is the one nobody asks and everybody should.
Five mistakes we see most
- Setting up a US LLC on a realtor’s suggestion. The hybrid mismatch between IRS and CRA treatment can produce double taxation that treaty relief only partly addresses.
- Putting a personal-use property into a Canadian corporation. The shareholder benefit arises annually and typically outweighs an estate tax that treaty relief already reduces to nil.
- Solving a problem that does not exist. Most families never run the pro-ration and never discover their exposure was zero.
- Taking single-country advice on a two-country question. A US adviser optimises the US side; a Canadian adviser optimises the Canadian side; the mismatch lands on the client.
- Ignoring the exit. Entry costs get priced. Unwinding costs almost never do, and they are frequently larger.
Frequently asked questions
alt=”” width=”1200″ height=”630″ />
Should I put my US property in a corporation?
For most snowbirds using the property personally, no. Corporate ownership of personal-use property can trigger an annual shareholder benefit in Canada, while the US estate tax it is meant to avoid is usually reduced to nil by treaty relief that costs nothing. The structure typically creates a recurring problem to solve a one-time problem that was already handled.
Why is a US LLC a problem for Canadians?
The IRS generally treats an LLC as a flow-through while the CRA generally treats it as a corporation. That mismatch can break the foreign tax credit mechanism that normally prevents double taxation, because the two countries disagree about who earned the income. Treaty relief exists for some hybrid situations but is not a complete answer.
What is a shareholder benefit?
Where a corporation owns property that its shareholder uses personally, the CRA can treat that use as a taxable benefit conferred on the shareholder — assessed annually, and typically measured by reference to the property’s value or an imputed rent. It is the main reason corporate ownership of recreational property is unattractive in Canada.
Does a trust work better?
Sometimes, and it is the structure most likely to be appropriate where structure is appropriate at all. But US grantor trust rules can defeat the purpose depending on how it is built, the Canadian 21-year deemed disposition applies, and it only works if you have genuinely given the property away. Costs are ongoing. For a single condo it rarely justifies itself.
What if I already have a structure in place?
The question changes from whether to build one to whether unwinding costs more than keeping it. Transferring property out is generally a disposition with its own tax consequences, so the answer is not automatically to dismantle it. Have it reviewed rather than assuming either way.
Is life insurance really a better answer than restructuring?
Frequently, where a genuine residual exposure exists. Insurance funds the liability rather than trying to eliminate it, creates no annual tax consequences, and can be adjusted or cancelled — none of which is true of a corporation holding real property.
Does my estate still have to file a US return if I own personally?
Yes, generally, where US-situs assets exceed US$60,000. That threshold is measured before treaty relief, so estates owing nothing still file. This is a paperwork obligation and not by itself a reason to restructure ownership.
What if my spouse is a US citizen?
The analysis changes materially, because the marital rules, QDOT considerations and US reporting obligations all enter the picture. Mixed-citizenship couples should treat this as a separate planning exercise rather than applying general guidance.
When does a structure actually make sense?
Broadly, when the property is an investment rather than a residence — multiple US properties, a genuine rental business, real liability exposure — or when the estate is large enough and US-weighted enough that treaty pro-ration does not cover the exposure. Succession complexity can also justify it.
What is the single biggest risk in this area?
Taking advice from someone who only sees one side of the border. A US adviser will optimise the US position and a Canadian adviser the Canadian one, and the cost of the mismatch between them lands entirely on the client — often years later, and often irreversibly.

The most valuable advice in this area is usually advice not to act. Structures are sold enthusiastically because they generate fees, and the families who most often end up in the wrong one are the ones who were told to do something rather than told to check first. Our cross-border estate planning work starts by quantifying whether there is anything to fix.
Before you restructure anything, find out whether you have an exposure at all — most people don’t, and the calculation takes an afternoon. Book a complimentary consultation and we will run your pro-ration, price the alternatives honestly, and tell you plainly if the answer is to leave it alone.
