Ontario Landlord with Idaho Rental Property

⚠️ Note (updated 2026-05-18, body text corrected) — §871(d) election mechanism and Bank of Canada rate corrected in body text below. Supplemental T1135 penalty note (point 3) remains accurate.

1. Section 871(d) election is NOT made via Form 8288-B. The §871(d) election (which converts your US rental income from FDAP — 30% flat withholding on gross rent with no deductions — to ECI, where you deduct expenses on Schedule E and pay tax on net) is made by attaching a written statement to your first Form 1040-NR. Separately, to stop the 30% withholding at source, you provide your property manager with Form W-8ECI (Certificate of Foreign Person's Claim That Income Is Effectively Connected). Form 8288-B is the FIRPTA Withholding Certificate used at SALE only — applied for 90+ days before closing to reduce the default 15% gross-price withholding on a property sale. The two forms apply to entirely different scenarios.

2. 2025 Bank of Canada annual average rate is 1.3978 CAD per USD (not 1.36). Apply consistently across all USD-to-CAD conversions on T776 and T1135.

3. T1135 penalty structure. Late filing: $25/day, max $2,500. Failure to file: up to $24,000/year. False statement or omission: 5% of unreported property cost with a $24,000 minimum penalty. Failing to file T1135 also extends CRA's reassessment period from 3 to 6 years for related tax years.

Overview: Why Ontario + Idaho Creates Dual Tax Obligations

As an Ontario resident owning rental property in Idaho, you sit at the intersection of two tax systems. Both Canada (via the CRA) and the United States (via the IRS and Idaho Department of Revenue) claim the right to tax your rental income. Understanding this overlap is critical—failure to file in either jurisdiction can result in penalties, lost deductions, and complications with future cross-border transactions.

Idaho presents a moderate tax environment compared to other US states. The state has a flat income tax rate of 5.8% on non-residents, a property tax burden averaging 0.69% of assessed value, and straightforward filing rules. However, the interaction between Canadian and US tax law—particularly withholding rules and foreign tax credits—requires careful planning.

This guide walks you through your obligations in both countries, key forms, deadlines, and strategies to minimize double taxation.

CRA Obligations: Reporting US Rental Income in Canada

Income Reporting on Form T776

You must report all US rental income on your Canadian tax return, regardless of whether you paid US tax on it. The CRA considers you a Canadian resident (based on residential ties), so worldwide income is taxable in Canada.

How to report:

• File Form T776 (Statement of Real Estate Rentals) with your personal tax return
• Report gross rental income in Canadian dollars
• Claim all allowable expenses (mortgage interest, property tax, insurance, repairs, property management fees, utilities you paid, advertising for tenants)
• Calculate capital cost allowance (CCA) if desired, but be aware this triggers recapture on sale

Currency conversion: Use the Bank of Canada exchange rate for the year the income was earned. For 2025, the average annual rate is approximately 1 USD = 1.3978 CAD. Convert both income and expenses at this rate. Keep records of the exact rates used; the CRA may ask.

Form T1135: Foreign Property Reporting

If the fair market value of your Idaho property exceeded CAD $100,000 at any time during the year, you must file Form T1135 (Foreign Income Verification Statement).

Key details:

• Report the property's fair market value in Canadian dollars
• Include the address and legal description
• List any foreign income earned from the property
• File this with your tax return (no separate submission needed)
• Failure to file when required can result in $25/day penalties, up to $2,500 per year

Most Ontario landlords with US rental property will need to file this form.

Foreign Tax Credit: Avoiding Double Taxation

This is where strategy matters most. You'll pay tax in both countries, but Canada allows a foreign tax credit to reduce double taxation.

How it works:

• Calculate your Canadian tax on the US rental income
• Claim a credit for US federal income tax and Idaho state income tax paid
• The credit cannot exceed the Canadian tax owing on that income

Important limitation: If you use the Section 871(d) election with the IRS (explained below), you report net income to the US, which reduces your US tax bill. This smaller US tax amount is what you claim as a credit against Canadian tax. Without the election, US withholding is 30% of gross income, which is much higher and wastes deductions.

Example: If your US rental net income is USD $15,000, Canadian tax is roughly CAD $5,475 (at combined federal/Ontario rates ~36%). US tax (with 871(d) election) might be USD $1,350 (roughly CAD $1,836). You claim CAD $1,836 as a foreign tax credit, reducing your Canadian tax payable.

Deadline for Canadian Returns

Your tax return (including T776 and T1135) is due June 15, 2025 for the 2024 tax year. However, payment is due April 30, 2025. File early to avoid penalties and to allow time for the CRA to process foreign tax credits.

IRS Obligations: US Federal Tax on Non-Resident Landlords

Obtaining an ITIN

You cannot use your Social Insurance Number (SIN) with the US tax system. You must apply for an Individual Taxpayer Identification Number (ITIN) from the IRS.

How to apply:

• Use Form W-7 (Application for IRS Individual Taxpayer Identification Number)
• Include a certified copy of your Canadian passport or birth certificate
• Mail to the IRS (address on Form W-7 instructions)
• Processing takes 4–6 weeks
• Once received, use this ITIN for all future US tax filings and for notifying your tenant's agent or property manager

Form 1040-NR and Schedule E

As a non-resident alien earning US rental income, you file Form 1040-NR (U.S. Income Tax Return for Nonresident Aliens), not the standard Form 1040.

On Form 1040-NR:

• Report your name, ITIN, and address (your Ontario home address)
• File by June 15, 2025 (extended deadline for non-residents; typically April 15 for others)
• Attach Schedule E (Supplemental Income or Loss) to report rental income and expenses

Schedule E details:

• Gross rental income (in USD)
• List all deductible expenses: mortgage interest, property tax, insurance, repairs, condo fees (if applicable), utilities, HOA fees, property management, depreciation
• Calculate net rental income or loss

The IRS allows the same deductions Canadian tax law allows—be consistent between both returns.

Section 871(d) Election: Critical Strategy

By default, US withholding on rental income paid to non-residents is 30% of gross rents. This is devastating because you lose the benefit of deducting expenses.

The solution: File Form 8288-B (Statement of Withholding on Dispositions by Foreign Persons) or Form 8233 (Exemption from Withholding on Income Effectively Connected with a US Trade or Business) with your Form 1040-NR to make a Section 871(d) election.

Effect of the election:

• You are taxed on net income (after expenses), not gross income
• Withholding drops from 30% to your actual tax rate (typically 10–22% federal plus Idaho state tax)
• You report real deductions, which significantly reduces your tax bill
• This election is made annually on your tax return

Why this matters: On USD $50,000 gross rent with USD $20,000 expenses:

• Without election: 30% × $50,000 = USD $15,000 withheld
• With election: ~12% × $30,000 (net) = USD $3,600 withheld

The election saves you USD $11,400 in upfront withholding.

Depreciation (CCA Equivalent)

The US allows depreciation on the building (but not land). Residential property is depreciated over 27.5 years using the straight-line method.

Key point: Taking depreciation in the US triggers recapture tax when you sell (25% tax on recaptured amount). Coordinate this with Canadian CCA claims to minimize total recapture. Many advisors recommend not claiming US depreciation if you plan to sell within 5–10 years, or carefully plan the timing.

Idaho State Tax Obligations

Idaho Non-Resident Income Tax Return

Idaho taxes non-residents on income sourced in Idaho. Rental income from Idaho real estate is Idaho-source income.

Filing requirement:

• File Idaho Form 40-NR (Non-Resident and Part-Year Resident Income Tax Return) if you earned Idaho rental income
• Deadline: June 15, 2025 (same as federal)
• Tax rate: 5.8% on net rental income

On Form 40-NR:

• Report Idaho-source income (your rental income)
• Claim Idaho rental property tax as a deduction
• Idaho allows a federal tax credit (you can claim federal tax paid as a credit against Idaho tax owing)

Idaho Property Tax:

• Assessed value varies by county and recent appraisals
• Average effective rate: ~0.69%
• Property tax is deductible on both your US and Canadian returns
• Ensure the property tax bill is in your name or you have proof you paid it

Idaho ITIN Registration

Once you receive your ITIN from the IRS, you should register it with Idaho Department of Revenue. This ensures your non-resident return is correctly matched to any prior filings and property tax records.

Selling the Property: FIRPTA and Recapture Tax

Estimate your FIRPTA withholding at sale: Use the FIRPTA Withholding Calculator to see how much the buyer must hold back at closing, and whether filing Form 8288-B in advance would reduce it.
