New Brunswick 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.

US Rental Property Ownership for New Brunswick Residents: A Complete Tax Guide

Owning rental property in the United States as a Canadian resident creates a two-country tax obligation. New Brunswick landlords who own income-producing real estate in Idaho must file returns and pay taxes to the Canada Revenue Agency (CRA), the Internal Revenue Service (IRS), and the State of Idaho. Each jurisdiction has different rules, deadlines, and withholding requirements. Understanding this framework upfront prevents costly penalties and ensures you're not paying more tax than legally required.

This guide walks you through the complete tax picture for a New Brunswick resident renting out property in Idaho.

Why This Combination Matters

New Brunswick has no provincial income tax on rental property—instead, you pay federal tax on 50% of net rental income under the federal capital gains inclusion rules. Idaho, however, imposes state income tax on non-resident rental income at a flat rate of 5.8%, plus property tax of approximately 0.69% (the state's average effective rate). The IRS also taxes US-source rental income at graduated rates (10% to 37% federal, 2025).

The complexity arises because:

• Three separate tax regimes apply simultaneously (CRA federal, IRS, Idaho state)
• Currency conversion is required (CRA uses Bank of Canada annual average rates)
• Withholding obligations vary by country and form type
• Foreign tax credits prevent triple taxation but require precise calculations
• Timing differences between CRA and IRS deadlines can create cash flow issues

CRA Obligations for Canadian Residents

Reporting Rental Income on Form T776

You must report all US rental income to the CRA on Form T776 (Statement of Real Estate Rentals), filed with your personal T1 return. Report amounts in Canadian dollars using the Bank of Canada annual average exchange rate for the year (2025: 1 USD = 1.3978 CAD).

On Form T776:

• Report gross rent received (converted to CAD)
• Deduct all allowable expenses: mortgage interest, property tax, insurance, utilities, repairs, condo fees, property management fees, and capital cost allowance (CCA)
• The net income flows to Line 10400 of your T1 General

Important: Rental property is not a capital asset for CRA purposes when held for income-producing use. However, the principal residence exemption does not apply to rental property.

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 Property Reporting) by June 15 (or December 15 if you have a December 31 year-end and file a request for adjustment).

On Form T1135, report:

• Address and description of the property
• Country (United States)
• Cost basis in Canadian dollars
• Fair market value at year-end in Canadian dollars
• Rental income earned during the year

Failure to file Form T1135 when required can result in penalties up to CAD $8,000 per year.

Calculating Foreign Tax Credit (FTC)

You are entitled to a non-refundable federal foreign tax credit for Idaho state income tax and US federal income tax paid. The FTC is calculated on Form T2209 (Federal Foreign Tax Credit).

The formula is: Foreign tax credit = (Net foreign-source income ÷ Worldwide net income) × Federal tax otherwise payable

This prevents you from being taxed twice on the same income. However, the FTC is limited—you cannot claim a credit larger than the Canadian tax you would have paid on that income.

Example: If you earned USD $10,000 net rental income (CAD $13,600), paid CAD $1,150 in Idaho state tax, and owed CAD $4,050 federal tax in Canada on that amount, your FTC would be limited to CAD $1,150 (the lesser of tax paid or tax owing in Canada).

IRS Obligations for Nonresident Alien Landlords

Obtaining an ITIN

Before filing any US tax return, you must apply for an Individual Taxpayer Identification Number (ITIN) using Form W-7 (Application for IRS Individual Taxpayer Identification Number). You cannot use your Canadian Social Insurance Number (SIN) for US tax purposes.

File Form W-7 with the IRS directly or submit it with your first US tax return. Processing takes 4–6 weeks. Your ITIN will be issued as a nine-digit number formatted XXX-XX-XXXX.

Filing Form 1040-NR and Schedule E

As a nonresident alien with US-source rental income, you must file Form 1040-NR (U.S. Nonresident Alien Income Tax Return) with the IRS by June 15 (later than residents, but penalties apply for late filing).

Attach Schedule E (Supplemental Income or Loss), which requires:

• Gross rent received (in USD)
• Property address and identification number (street address or parcel number)
• Mortgage interest, property tax, insurance, utilities, repairs, and other deductible expenses
• Net rental income or loss

Key rule: As a nonresident, you can only deduct expenses directly attributable to the US rental property. General living expenses and home office costs allocable to US rental activities are NOT deductible.

Section 871(d) Election: Electing Treaty-Based Position Disclosure

The default US federal withholding rate on nonresident rental income is 30% of gross rents. However, Canada-US tax treaty benefits allow you to elect under Section 871(d) to be taxed on net income instead of gross income, with graduated federal tax rates (10% to 37%) rather than a flat 30%.

To make this election:

1. Attach a completed Form 8288-B (Certificate of Withholding - U.S. Property Disposition by Foreign Persons) or written declaration to your Form 1040-NR
2. Declare your intent to file a timely return
3. Provide your ITIN

If you make this election and file on time, withholding is reduced from 30% to zero (or minimal), and you pay tax calculated on your actual net income. This election typically results in significant tax savings and is the preferred approach for Canadian landlords.

Idaho State Income Tax

Non-Resident Filing Requirement

Idaho taxes non-resident individuals on all income derived from Idaho sources. As a non-resident landlord, you must file Form 40 (Idaho Individual Income Tax Return) Schedule NR by April 15.

Idaho's flat income tax rate is 5.8% on taxable income. Unlike the federal system, Idaho does not use graduated brackets for non-residents—all income is taxed at 5.8%.

Allowable Deductions

On your Idaho return, you may deduct:

• Mortgage interest (both principal and interest portions)
• Property tax (Idaho's average effective rate is 0.69% of property value)
• Insurance premiums
• Utilities
• Repairs and maintenance
• Depreciation (if elected)

Idaho does not allow a standard deduction for non-residents claiming itemized deductions against real property.

Estimated Tax Payments

If you expect to owe more than USD $500 in Idaho state income tax for the year, you must make quarterly estimated tax payments on:

• April 15 (for Q1)
• June 15 (for Q2)
• September 15 (for Q3)
• January 15 next year (for Q4)

File Form 40-ES (Idaho Estimated Income Tax Payment Voucher) with each payment. Failure to pay estimated tax can result in penalties and interest.

Selling the Property: FIRPTA Withholding

When you sell your Idaho rental property, the IRS requires FIRPTA (Foreign Investment in Real Property Tax Act) withholding unless you qualify for an exception.

FIRPTA Withholding Rate

The buyer or their agent must withhold 15% of the sale price and remit it to the IRS within 10 days of closing. If the property is sold for less than USD $300,000 and the buyer intends to use it as a personal residence, withholding may not apply—but the burden is on the buyer to claim the exemption.

Avoiding Overpayment

If you expect to owe less federal tax than 15% of the sale price, you can request a Certificate of Withholding (Form 8288-B) from the IRS before closing, certifying that a lower withholding is appropriate. This requires IRS approval and advance application.

Reporting the Sale

Report the sale on:
