Rent out a property in another country and the same rent is taxed twice on paper: first by the country where the property sits, then by Canada or the United States when the owner reports worldwide income. The foreign tax credit collapses those two bills into roughly the higher of the two, and for most landlords it works. It fails for landlords stuck in a gross-withholding regime with no net election, straddling mismatched tax years, or selling after decades of depreciation the source country never recognized.
Our read: where the source country offers a net-basis election, file it, and claim the home-side credit against the final source-country liability rather than the amount withheld. The double tax that survives is rarely on the rent itself. It shows up in the plumbing: stranded credits, currency drift between when the rent was earned and when the tax was paid, and the US depreciation-recapture layer at sale.
Why two countries can tax the same rent
Every major tax treaty starts from the same allocation. Article 6 of the OECD Model Tax Convention says income from immovable property “may be taxed” in the country where the property is situated, which gives the situs country the first bite.[OECD Model Tax Convention on Income and on Capital, Article 6 — Income from Immovable Property, 2026-07] Article VI of the Canada-US treaty carries the identical rule for property on either side of that border.[Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, Article VI, 2026-07]
Note what the treaty does not say. It never turns off the home country’s claim. Canada taxes its residents on worldwide income, the United States taxes its citizens and residents the same way, and the rent lands on both returns by design. Relief arrives at the second stop, where the home country credits the income tax the source country collected first.
The citizenship lens differs. A Canadian owner is caught by residence: cease Canadian residency and the worldwide net lifts, at the price of the deemed disposition covered in departure tax on foreign property. A US citizen is caught for life regardless of address under the citizenship-based system; the same reporting follows an American landlord from Austin to Lisbon.
Gross withholding or the net election at the source
Source countries tax non-resident landlords one of two ways: a flat withholding on gross rent, or an assessed tax on net rental profit. Most default to the withholding and offer the net treatment as an election. The two regimes CrossingHQ readers most often face are the US and Canada themselves, near mirror images:
| Source country | Default on gross rent | Net election | The paperwork |
|---|---|---|---|
| United States (non-resident owner) | 30% withholding on gross, no deductions | Section 871(d) election: rent treated as effectively connected income, graduated rates on net profit | Election statement attached to Form 1040-NR; Form W-8ECI to the withholding agent |
| Canada (non-resident owner) | 25% Part XIII withholding on gross | Section 216 return: Part I tax on net rental income | T1159 return, due within two years, or by June 30 of the following year once an approved NR6 is in place; Form NR6 to withhold on projected net during the year |
Electing under section 871(d) treats the rental as effectively connected with a US trade or business, opening the door to expenses and graduated rates.[IRS, Nonresident aliens — Real property located in the U.S., 2026-07] Canada’s Part XIII withholding is refundable in part once a section 216 return taxes the net instead; an NR6 filed before the first rent payment of the year lets the agent withhold against projected net.[CRA, Electing under section 216 of the Income Tax Act, 2026-07]
The math is not close for mortgaged properties. A landlord carrying mortgage interest, management, insurance, and repairs often nets 40 to 60 cents of profit per dollar of rent, so a flat quarter or third of the gross routinely exceeds any reasonable tax on the net. The gross default wins only for an owner with almost no deductible costs and no appetite for a second country’s filings. Either election, once made, commits the owner to filing in the source country every year the rent flows.
Third countries run their own versions of the same fork, with their own rates, deduction rules, and in the EU a residence-based split between EU and non-EU landlords. Those specifics live on the country pages; a Canadian renting out a Mexican condo should start with taxes for Canadian buyers in Mexico, and each country hub carries the matching page for American owners.
The home-side return runs on different rules for each passport
Canadian residents: worldwide rent, optional depreciation
A Canadian resident reports foreign rental income on the T1 in Canadian dollars, net of the same expense categories a domestic rental would carry. The form-level walk-through, including the T776 mechanics, lives in CRA rules for foreign rental income; the property almost always also triggers the T1135 foreign-property disclosure, an information return, not a second tax.
The Canadian quirk: capital cost allowance is elective. CRA’s rental guide is explicit that a filer can claim anywhere from zero CCA to the year’s maximum.[CRA, Guide T4036 Rental Income — capital cost allowance rules, 2026-07] That choice matters more for foreign property than domestic. When the source country’s tax already equals or exceeds the Canadian tax on the same rent, the foreign tax credit absorbs the whole Canadian bill; a CCA claim saves nothing today while building a recapture liability for the year of sale. Skipping CCA in high-foreign-tax years is the standard play, a choice a US owner does not get; the year-by-year mechanics of that choice, and the section 45 elections that sit beside it, are in foreign rental property elections for Canadians.
A loss still gets reported, and what happens to it next has its own rules; see rental loss carryforwards on foreign property.
US persons: Schedule E and the mandatory depreciation quirk
An American reports foreign rental income on Schedule E as if the property stood in Ohio, in US dollars, with the same expense categories. The difference is depreciation. It is not optional, and for foreign residential property it runs on the Alternative Depreciation System: straight-line over 30 years for property placed in service after 2017, 40 years for earlier, against the 27.5 years a domestic residential rental gets.[IRS, Publication 527, Residential Rental Property — ADS recovery periods for property used outside the United States, 2026-07]
The trap in “not optional” is the allowed-or-allowable rule. The IRS reduces the property’s basis by the depreciation that was allowable every year whether or not the owner claimed it. An American who skips depreciation gets no deduction during the holding period and still pays recapture-priced tax at sale on deductions never taken. Whatever the source country’s rules say, the US depreciation runs; most countries in this library give individuals no equivalent deduction, the seed of the recapture asymmetry covered below.
How the foreign tax credit meshes, and where each version leaks
Both home countries relieve the double tax through a credit, and the credits fail in different places:
| United States (Form 1116) | Canada (T2209) | |
|---|---|---|
| Basket | Passive category income | Non-business income tax, computed per country |
| Ceiling | US tax multiplied by the foreign-source share of taxable income | Canadian tax on the foreign income, per section 126 |
| Excess credit | Carried back 1 year, forward 10 | No carryback or carryforward |
| Fallback for stranded tax | Itemized deduction, only by forgoing the credit for all foreign taxes that year | Subsection 20(12) deduction against income |
| 15% cap on creditable tax | Not applicable | Does not apply to real-property income |
The US credit runs through Form 1116 in the passive basket; unused credit carries back one year and forward ten, and the baskets, the limitation math, and the carryover ordering have their own page in the Form 1116 foreign tax credit guide.[IRS, Publication 514, Foreign Tax Credit for Individuals — carryback and carryover, 2026-07] The Canadian credit is built on section 126, computed country by country, and two of its features decide rental outcomes: unused non-business credits cannot move to another year, and the 15% cap on ordinary investment income does not reach real-property rent.[CRA, Income Tax Folio S5-F2-C1, Foreign Tax Credit, 2026-07] The T2209 mechanics, the subsection 20(12) salvage, and a worked Spanish-rental example are on the Canadian foreign tax credit page.
Two operating rules apply on both sides. First, the credit attaches to the final source-country liability, not the amount withheld: a landlord who had 25% of gross withheld and then filed the net-basis return credits only the assessed net tax, and a later refund claws the credit back. Second, the ceiling is set by home-side tax on that income, so a low-income owner, a retiree on modest pensions, can watch foreign tax exceed the ceiling with nowhere to put the excess. The American carries it forward ten years; the Canadian deducts the stranded portion under subsection 20(12) and recovers cents on the dollar.
Timing and currency mismatches that strand credits
The credit assumes the foreign tax and the income land in the same home-country tax year at comparable exchange rates. Neither assumption holds reliably.
Year misalignment is the common one. Rent earned in 2026 can be assessed by the source country in a return filed and paid in 2027, and a cash-basis US filer claims the credit in the year the tax was paid unless an accrual election is in place. Income and credit then sit in different years; the one-year carryback on Form 1116 exists largely to stitch that seam. A Canadian has no carryover to lean on. The section 126 credit is claimed for taxes paid in respect of the year’s income, which in practice means adjusting the earlier return once the foreign assessment lands.
Currency drift is quieter. Rental income converts to home currency at the rate when earned or received; the foreign tax converts at the rate when paid, a rule Publication 514 states directly for US filers. A source-country currency that fell 10% between the rental year and the tax-payment date shrinks the credit while the income stayed booked at the higher rate. Neither system compensates for the gap. It is a structural cost of holding a rental in a weakening currency, and it compounds with the withholding-versus-assessment timing above.
The sale is where the symmetry breaks
During the rental years, the credit does most of its job. At sale, the two home regimes diverge sharply.
The American problem is recapture on depreciation the source country never saw. Thirty years of mandatory ADS depreciation drains the US basis whether claimed or not, so the US gain at sale exceeds the source-country gain by the accumulated depreciation. The depreciation-attributable slice is taxed as unrecaptured section 1250 gain at up to 25%.[IRS, Topic No. 409, Capital Gains and Losses — unrecaptured section 1250 gain rate, 2026-07] The source country taxes its smaller gain, and the credit for that tax offsets the US tax on the overlapping portion; the recapture layer sits on gain the source country never taxed, so there is no foreign tax to credit against it. That slice is US-only tax, priced in the day a US person puts a foreign property into rental service.
The Canadian side of the same event is elective. Claimed CCA comes back into income as recapture in the year of sale, fully taxable, on top of the half-taxable capital gain. A Canadian who skipped CCA through the holding years has no recapture layer at all. That single difference, elective depreciation against mandatory, is the cleanest asymmetry in the whole cross-border rental stack.
Who ends up double taxed despite the credit
The mechanism has losers, and they are identifiable in advance. The owner in a gross-withholding country with no net election and a thin home-side tax bill wears both layers: the withholding is fixed, the credit ceiling is low, and for a Canadian the excess cannot move to another year. Residents of US states with an income tax carry a second permanent layer: states generally allow no credit for foreign income taxes, so the federal credit zeroes the federal overlap while the state taxes the same rent in full.[KSM (Katz, Sapper & Miller), Combating Double Taxation: Foreign Tax Credits and Tax Treaties — state-by-state treatment of foreign taxes, 2026-07] The American seller after a long hold faces the recapture layer no treaty relieves. And a property that produced no rent still generates the cheapest but most common version: foreign property taxes, IBI, predial, and their cousins are not income taxes, earn no credit anywhere, and become a carrying cost twice over when the home side offers no deduction either.
FAQ
Is foreign rental income really taxed twice? It is reported and assessed twice, and paid roughly once when the mechanics work. The combined bill tends toward the higher of the two countries’ taxes on the rent. The genuine double payments concentrate in the edge cases: stranded credits, state-level tax, and US depreciation recapture.
Does the tax withheld abroad count as my credit, or the final bill? The final bill. Withholding is a collection device; the creditable amount is the source country’s assessed liability for the year, and a refund after a net-basis filing reduces the credit with it.
Does Canada’s 15% limit on foreign tax credits apply to rental income? No. The 15% cap and the related subsection 20(11) deduction apply to foreign property income other than real or immovable property. Foreign tax on rent from real property is creditable in full up to the section 126 ceiling, with subsection 20(12) as the fallback for any stranded excess.
Do I still file at home if the property lost money? Yes, on both sides of the border. A US owner reports the loss on Schedule E, subject to the passive-loss rules. A Canadian reports it on the T1, where it can offset other income or carry forward; the mechanics are in rental loss carryforwards on foreign property. A loss year usually still triggers the T1135 disclosure.

This page owns the treaty and credit mechanics; the operational detail branches from here. The taxes hub maps the full set. For the concept layer, read double taxation explained and the Canada-US tax treaty guide. Canadians filing their first foreign-rental year should work through CRA rules for foreign rental income alongside the T1135 disclosure rules. Country-specific rates and elections live on each country’s buyer tax pages, starting with Mexico for Canadian buyers. Owners planning to leave Canada with the property should price the deemed disposition in departure tax on foreign property first.
