Canadian owners buying US rentals: why a domestic LLC guide is not enough

A Canadian resident buying a US rental needs the two countries' treatment to fit together. A domestic US guide can explain how an LLC works for a US owner while leaving important Canadian tax, credit and reporting questions unanswered.

This checklist starts with a Canadian tax resident who is neither a US citizen nor a US tax resident, considering an ordinary US investment rental. Different citizenship, residence, personal-use or corporate ownership facts need a different plan. The illustrative withholding calculations use 2025 and USD.

Classify the actual owner in both countries

Begin with US rental ownership: personal title, LLC, and corporate taxation. A US domestic LLC may be disregarded, a partnership or corporately taxed for US federal purposes. That choice does not establish how Canada classifies the same legal entity. The IRS LLC page describes the US starting point.

CRA's archived Technical News 44 gives a historical example of a US LLC treated as a corporation in Canada but fiscally transparent in the US. It demonstrates why a mismatch needs investigation, not a current ruling for every LLC. See the archived CRA discussion of a US LLC with a Canadian branch. Have advisers classify the proposed entity using its governing law, agreement and current rules before you sign.

An S corporation election is also not available to every proposed owner: US nonresident alien shareholders are ineligible under the IRS requirements. A Canadian address alone does not establish the person's US tax status, so confirm the facts.

Ask how the income and tax line up

Canada generally taxes residents on worldwide income. US rental income and a later gain therefore need Canadian analysis even when the US already taxes them. A foreign tax credit has conditions and limits; it is not simply every dollar remitted to the IRS subtracted from Canadian tax. See CRA foreign-tax-credit folio.

Ask who earns the income, who legally owes the tax, which year each country recognizes it, and what currency conversion applies. Model rent, distributions and sale separately. Classification or timing differences can prevent the expected match.

The Canada–US convention contains real-property, gains, double-taxation and fiscal-transparency provisions. Articles IV(6)–(7) make entity treatment relevant to treaty analysis. Do not assume that the treaty automatically cures an LLC mismatch or removes all US rental tax.

Understand rent withholding before measuring cash flow

For a nonresident alien's US real-property income not effectively connected with a US trade or business, the IRS describes a general 30% gross-income tax, subject to any applicable treaty reduction. A timely section 871(d) election can, where available, bring qualifying property income into net-income treatment with attributable deductions and graduated tax. See IRS nonresident real-property guidance.

For a hypothetical direct owner with USD 36,000 annual passive rent under an assumed 30% gross-basis regime, the gross amount is USD 10,800: 36,000 × 30%. It is not 30% of profit after mortgage payments.

This shows why the reporting/election plan belongs in the purchase budget. It does not establish that USD 10,800 is the owner's final liability under a different regime. Have the US preparer confirm the election, return, documentation and withholding treatment before asking a manager to stop withholding. Opening an LLC is not that instruction.

Sale withholding is not the tax on the gain

The Foreign Investment in Real Property Tax Act, or FIRPTA, generally requires withholding of 15% of a foreign seller's amount realized. Exceptions and withholding certificates can change the amount. The IRS FIRPTA page explains the framework.

Suppose a separate hypothetical direct-owner sale to an investment buyer has USD 500,000 amount realized. Assume no exception or reduced certificate. General withholding is USD 75,000: 500,000 × 15%. That calculation uses amount realized, not the owner's gain or cash after paying off the mortgage.

Plan closing liquidity and the later tax-return reconciliation. Do not describe all USD 75,000 as the final tax, or claim it all as a Canadian foreign tax credit without the eligibility/reconciliation analysis. CRA's credit guidance excludes tax that is refunded from the qualifying amount.

Put information returns on the checklist

For a foreign-owned US domestic disregarded entity with reportable related-party transactions, Form 5472 and a pro forma Form 1120 can be required. Contributions and distributions can be relevant. The Form 5472 instructions explain the trigger and USD 25,000 failure-to-file penalty. No separate ordinary income-tax bill does not mean no entity reporting.

On the Canadian side, assess Form T1135 when aggregate specified foreign property cost exceeds CAD 100,000 at any time in the year, subject to exclusions. Cost is not mortgage equity, and income reporting does not begin only after that threshold. CRA T1135 questions explains both points. Corporate/foreign-affiliate ownership can create different reporting questions; have the preparer identify the relevant forms rather than adding every form indiscriminately.

Coordinate borrowing and succession before choosing title

Get a written lending proposal for the actual owner, guarantees and currency. Confirm insurance and property-state requirements. Review how exchange-rate changes affect funding and cash returned to Canada; do not quote a universal foreign-buyer loan limit.

Ask an estate adviser about US-situated assets, filing duties, probate, incapacity and available treaty relief. The IRS nonresident estate page establishes that this needs a separate review. It is not settled by the Canadian death-tax calculation or an LLC membership transfer.

Make the Canadian and US advisers review one ownership diagram and one projection covering purchase, rent, distributions, sale and death. Request a list of filings, deadlines and costs for each proposed structure. If Canadian residence will change, Leaving Canada with rentals or company shares: ownership structure matters raises a further planning question. Choose the entity only after that joint review explains the full cycle.
