Whenever I am speaking to a Canadian client about buying rental properties in the US, taxes always come up. But while most investors are focused on income tax and capital gains, there is another huge US tax that most people either do not know about, or do not want to think about: US estate tax.
On paper it looks alarming. Your US property is a US asset, so when you die the IRS can tax its value at rates up to 40%, after an exemption of just $60,000. For a $500,000 property, that could mean a tax bill of $200,000.
But the part that the scaremongers leave out is the fact that the Canada-US tax treaty gives Canadians a far bigger exemption than the $60,000 allowed to most foreigners. For most of my clients, that means their actual US estate tax bill is likely to be closer to zero.
I have had this exact conversation with investors who are buying specifically to leave something to their children, so let me walk you through how it really works, and when it stops being a paperwork exercise and becomes something real to actually plan for.
First, what US estate tax actually is
US estate tax is a tax on transferring your assets to your successors when you die.
Typically, two things trip Canadians up straight away. First, it is charged on the fair market value of what you owned, not on any gain and not on your equity, so a mortgage does not automatically shrink it. Second, it is a completely separate tax from income tax and from FIRPTA.
People blur all three together. Income tax is on the rent you earn each year, and I cover that in my US tax guide for Canadian investors. FIRPTA is a withholding on the sale of the property, a prepayment against capital gains. Estate tax is neither of those. It only comes up on death, and it is charged on value, not profit. The top rate is 40%.
Why your US rental is caught
The US taxes non-residents on their US-situs assets, meaning assets treated as located in the United States. US real estate is always US-situs. So your Kansas City or Cleveland rental counts, full stop.
Not everything a Canadian might hold in the US is taxable. US bank deposits that are not tied to a US business, US Treasury securities, and life insurance proceeds on your own life are generally not classed as US-situs. But real estate is, and so are shares in US companies, which catches people who also hold US stocks.
The scary number: the $60,000 exemption
Here is where the alarming headlines come from. Under US domestic law on its own, a non-resident gets a credit that exempts only $60,000 of US-situs assets. Everything above that is exposed, at rates running up to 40%.
Run that against a $163,000 rental and it looks frightening: tax on roughly $103,000 of value. If that were the whole story, US real estate would be a bad idea for almost every Canadian. But of course it is not the whole story, because it completely ignores the treaty.
How the Canada-US treaty rescues most Canadians
The Canada-US tax treaty, at Article XXIX-B, lets a Canadian claim a prorated share of the same exemption a US citizen gets, which is $15 million per person in 2026. You claim the greater of the basic $60,000-level credit or this prorated amount.
The proration is simple both in theory and practice. Your share of the big exemption equals the full US exemption multiplied by your US-situs assets divided by your worldwide estate. So if your US property is a small slice of your total net worth, your prorated exemption is large.
Here is a simple illustration with round numbers. Say you hold a US rental worth $200,000 and your worldwide estate, everything you own anywhere, is $2 million. Your US assets account for 10% of your total estate, so you get 10% of the standard $15 million allowance, which is $1.5 million. That dwarfs the $200,000 property, so the US estate tax comes out at zero.
The practical rule of thumb: if your worldwide estate is comfortably under $15 million, the treaty almost always reduces your US estate tax to nothing. There is also a treaty marital credit that can roughly double the relief on assets passing to a spouse.
You can see how different ownership structures also play a part in estate tax planning in my guide to how to structure your US property investment.
A real example: Ronald's legacy portfolio
One of my clients, Ronald from Ottawa, bought his Kansas City rental specifically to build something to pass on to his children, so estate planning was a real question for him from the start, not an afterthought.
We ran it through. Ronald's US real estate is a small fraction of his overall net worth, so under the treaty his prorated exemption is far larger than the value of the property, and his projected US estate tax is zero.
What his family will still need to do, when the time eventually comes, is file the US estate tax return, because his US assets are over $60,000. That filing is not about paying tax. It is what secures the treaty position and lets his heirs take clean title to the property. More on that below.
When it becomes something to plan for
Estate tax stops being a paperwork item and becomes a genuine planning problem in a few situations: when your worldwide estate approaches or passes $15 million, so the prorated exemption no longer covers everything; when you build a large US portfolio, so your US assets become a big share of your estate; when you hold a lot of US stocks on top of property, since those are US-situs too; and, bluntly, when nobody files the return and the estate gets tangled up later. If you are in any of those camps, this is worth real, paid advice well before it matters.
Structures, and why the obvious ones can backfire
This is where Canadians get sold expensive solutions they do not need. Here is how the common structures actually behave for estate tax.
How common ownership structures affect US estate tax| Structure | Effect on US estate tax | The trade-off |
|---|
| Personal name | US real estate is US-situs, fully exposed (treaty relief applies) | Simplest and cheapest, may struggle to finance without a US legal entity (LLC or LP) |
| Single-member LLC | No change; the LLC is disregarded, the property is still US-situs | Feels like protection, gives none here |
| Limited Partnership (LP) | Underlying real estate still US-situs; good for income tax, not an estate-tax shield by itself | Sensible for Canadians on income tax, neutral on estate tax |
| Foreign (non-US) corporation | Shares of a foreign corp are non-US-situs, so this can move the asset outside US estate tax | Most DSCR lenders will not finance a property held by a foreign corporation, plus corporate tax and complexity |
| Cross-border or irrevocable trust | Can remove assets from your estate and avoid probate | Real setup and annual cost, overkill for one or two properties |
| Non-recourse mortgage | Reduces the taxable US-situs value of the property | Leverage you likely wanted anyway, so it works in your favor |
The one thing to remember: an LLC feels like a shield but does nothing for US estate tax, and for Canadians it also creates the income-tax mismatch I explain in my guide to LP vs LLC for Canadians. Do not treat an LLC as an estate plan.
With Ronald we looked hard at the fancier options.
A foreign corporation would have moved the property outside US estate tax on paper, but it would have killed his DSCR financing, because the specialist lenders will not lend to a foreign corporation. So that was off the table.
We looked at a trust, but for one or two properties the cost simply was not justified. The treaty already covers him.
The plan is to revisit a trust once he is at five or more properties, when avoiding probate across multiple states starts to earn its keep. Staged, appropriate to where he actually is, and not a dollar spent on a structure he does not yet need. Boring, again, wins.
What to actually do
Keep it simple while your US holdings are small, because the treaty is doing the heavy lifting for you. Make sure whoever will handle your estate knows to file Form 706-NA, even when no tax is due, to claim the treaty position and obtain the IRS transfer certificate your heirs need to deal with the property.
The IRS confirms the filing requirement kicks in once US-situs assets exceed $60,000. Use a cross-border CPA or estate lawyer rather than a general one, revisit your structure as the portfolio grows, and once you are at real scale, look at whether life insurance should cover any future liability.
Much of this sits alongside the wider setup covered in my Canadian guide to buying US rentals, and you can run your own numbers with the free tools in my foreign investor starter kit.
The bottom line
For most Canadians with a rental or two, US estate tax is a filing to remember, not a bill to fear, because the treaty reduces the tax to zero. It becomes a real planning problem only at genuine scale or with a large worldwide estate. Do not let a scary $60,000 headline frighten you into an expensive structure you do not need, and do not ignore the paperwork either.
Remember, this is a game of probabilities. Plan properly for what is likely, stay flexible for the rest, and get the right professional in the room before your estate is big enough to matter.
