Ontario Landlord with South Carolina 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 Ontario Residents: A South Carolina Tax Guide

As an Ontario resident who owns rental property in South Carolina, you operate in a complex tax environment. You must satisfy three tax authorities: the Canada Revenue Agency (CRA), the US Internal Revenue Service (IRS), and the South Carolina Department of Revenue. Each has different rules, forms, and deadlines. Understanding these obligations prevents penalties, missed deductions, and unnecessary withholding.

This guide focuses on the specific tax treatment for non-resident alien (NRA) landlords and how to optimize your position across both countries.

Why Ontario + South Carolina Creates Special Tax Complexity

South Carolina is a popular investment destination for Atlantic Canadian landlords seeking rental income and property appreciation. However, this jurisdiction combination triggers mandatory reporting in both countries and two different income tax systems operating simultaneously.

The core issue: The CRA and IRS both claim taxing rights on your worldwide income, including US rental revenue. Without proper planning and forms, you'll face:

• 25% Canadian withholding tax on gross rents (Part XIII under the Income Tax Act)
• 30% US federal withholding on gross rents
• South Carolina state income tax at 6.5%
• Double taxation without a foreign tax credit claim

The solution is strategic filing and the Section 871(d) election, which allows you to report actual net rental income (rents minus expenses) instead of paying withholding on gross amounts.

CRA Obligations for Ontario Landlords

Filing Form T776

You must report all US rental income on a Canadian T776 (Statement of Real Estate Rentals). The T776 is filed as part of your personal tax return (Form T1 General) each year.

On the T776:

• Report gross rental income in Canadian dollars
• Claim all deductible expenses (mortgage interest, property tax, insurance, utilities, repairs, property management fees, depreciation)
• Convert US amounts to CAD using the Bank of Canada annual average exchange rate. For 2025, use 1 USD = 1.3978 CAD
• Include South Carolina property tax (0.57% average effective rate on assessed value), US mortgage interest, and homeowner insurance

Form T1135 Foreign Property Reporting

If your South Carolina rental property's adjusted cost base (ACB) exceeds CAD $100,000, you must file Form T1135 (Foreign Income Verification Statement).

This form is filed with your tax return and requires you to:

• Declare the property address and legal description
• Report the cost basis in Canadian dollars
• Report the fair market value (FMV) in Canadian dollars
• Specify the type of property (residential rental)

Failure to file T1135 when required triggers a $2,500 penalty, plus additional penalties if the omission is intentional.

Foreign Tax Credit

South Carolina and US federal income taxes paid are eligible for a Federal Foreign Tax Credit on Form T776 and Schedule 1 (Form T1 General). This credit prevents you from paying the same income to two countries.

To claim the foreign tax credit:

• Calculate Canadian tax on worldwide income (including US rental income converted to CAD)
• Calculate the US federal and state income tax paid
• The foreign tax credit is limited to the lesser of: (a) foreign tax paid, or (b) Canadian tax attributable to the foreign income

Example: If you pay $3,000 USD (≈ $4,080 CAD) in combined US federal and South Carolina taxes on your South Carolina rental income, and your Canadian tax on that same income would be $5,200 CAD, your foreign tax credit is $4,080 CAD.

IRS Obligations for Non-Resident Alien Landlords

Obtain an ITIN

Non-resident aliens cannot use a Canadian Social Insurance Number (SIN) with the IRS. You must apply for an Individual Taxpayer Identification Number (ITIN) using Form W-7.

File Form W-7 with the IRS (Philadelphia campus for mailed applications):

• Submit a completed W-7 application
• Include a copy of your passport as identification
• A passport copy also serves as proof of foreign status
• Processing takes 11–21 days when filed electronically

Use your ITIN on all US tax forms once issued.

Form 1040-NR: US Non-Resident Alien Tax Return

File Form 1040-NR (U.S. Non-Resident Alien Income Tax Return) annually. This is separate from your Canadian T1 General return.

On Form 1040-NR:

• Report gross rental income from Schedule E (Part I)
• Deduct all allowable rental expenses on Schedule E (Part II)
• Calculate net rental income
• File by June 15 (three-month extension available to September 15)

Schedule E and Rental Income

Schedule E (Part I) is where you report South Carolina rental income:

• List gross rents received
• Deduct mortgage interest, property tax, insurance, repairs, maintenance, utilities, HOA fees, property management fees, and advertising
• Do NOT claim depreciation if you've elected under Section 871(d) (see below)

Section 871(d) Election: The Game-Changer

This is the most important decision for your US tax position.

Without Section 871(d):

• You pay 30% withholding on gross rental income
• You file Form 1040-NR but withholding is calculated on top-line revenue
• You cannot easily recover withheld amounts

With Section 871(d):

• You report net rental income (rents minus expenses) on Form 1040-NR
• You pay tax only on profit, not gross revenue
• Your US federal withholding obligation drops dramatically
• You must file Form 8288 and work with your US property manager or tenants to avoid backup withholding

To make the Section 871(d) election:

• File Form 8288-B (Application for Withholding Certificate for Dispositions by Foreign Persons of US Real Property Interests) with the IRS
• Request withholding on net income, not gross
• Provide your ITIN
• Once approved, furnish the withholding certificate to your property manager or management company

Without this election and proper forms, your property manager may withhold 30% of every rent payment, creating significant cash flow problems.

South Carolina State Income Tax

South Carolina taxes non-resident rental property owners at a flat 6.5% state income tax rate on net rental income.

You must file:

• South Carolina Form SC 1040 (Non-Resident or Part-Year Resident)
• South Carolina Schedule C or Schedule E (for rental income)
• File by April 15 (same as US federal)

South Carolina allows deductions for:

• Mortgage interest
• Property tax
• Insurance
• Repairs and maintenance
• Property management fees
• Utilities
• Depreciation (if not claimed federally)

However, South Carolina does not allow a foreign tax credit. You cannot credit US federal withholding against SC state tax. This means you pay SC tax on top of any federal tax.

Property Tax Consideration: South Carolina's average effective property tax rate is 0.57% on assessed value. This is significantly lower than Ontario, making SC attractive for rental property investors.

Selling Your South Carolina Property: FIRPTA

When you eventually sell, FIRPTA (Foreign Investment in Real Property Tax Act) applies. This US law requires:

• The buyer to withhold 15% of the net sale proceeds (not the gross sale price)
• You file Form 8288 (U.S. Withholding Tax Return for Dispositions by Foreign Persons of U.S. Real Property Interests) to report the transaction
• Within 20 days of closing, the buyer must remit the withheld amount to the IRS

You'll also file Form 1040-NR to report the gain and claim any available exemptions. Work with a US cross-border tax professional before selling.

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.
