Canadian Tax Guide for Non-Resident U.S. Property Sellers in 2025

Selling Canadian property as a non-resident can feel overwhelming, especially when you discover that up to 35% of your sale proceeds could be withheld for taxes. When you sell property as a non-resident, there are important tax considerations and compliance steps to keep in mind. Whether you’re disposing of a family cottage, rental property, or former residence, understanding Canada’s tax obligations is crucial for protecting your financial interests.

The good news? With proper planning and the right documentation, you can significantly reduce these withholding taxes and potentially recover excess amounts through filing a Canadian tax return. However, the process involves additional paperwork, especially for non-residents. This guide walks you through some essential steps, from obtaining compliance certificates to understanding your filing obligations.

Recent changes have made this process even more critical. As of January 2025, the default withholding tax rate increased from 25% to 35% of the gross sale price. Additionally, processing times for certificates of compliance have extended to over six months, compared to the previous 30-60 day timeframe. Understanding tax considerations is essential for non-residents selling property in Canada.

Understanding Canadian Withholding Tax

Canada’s tax system requires both individuals and businesses to report and pay tax on income earned within the country, as well as on worldwide income if you are a Canadian resident. If you own U.S. property, it’s important to understand the tax implications for your Canadian tax liability. The Canada Revenue Agency (CRA) oversees the administration of Canadian taxes, and all Canadian residents must file a tax return each year, declaring income from both Canadian and foreign sources—including any gains or rental income from U.S. property.

To avoid double taxation, Canadians can claim a foreign tax credit for taxes paid to the U.S. on their tax return. This tax credit helps reduce your Canadian tax liability by offsetting the taxes already paid in the U.S., ensuring you are not taxed twice on the same income. Understanding how to properly report your worldwide income and utilize available tax credits is essential for managing your Canadian tax obligations and minimizing your overall tax liability.

When you sell Canadian real estate as a non-resident, Canada Revenue Agency (CRA) requires tax withheld to ensure you meet your tax obligations. This tax withheld happens automatically at closing, but the amount depends on which method applies to your situation. If excess tax withheld occurs, you can recover the overpaid amount by filing a Canadian tax return.

Default Withholding Method

Without taking any advance action, your lawyer will withhold 35% of the entire sale price for non-depreciable property like land or residential real estate. For depreciable property such as rental buildings, the withholding increases to 50% of the sale price.

 

Certificate of Compliance Process

The Certificate of Compliance application uses Form T2062 and must be submitted before the 10th day following your property’s closing date. It is important to notify the CRA promptly about the property disposition to avoid potential penalties for late disclosure. However, smart planning involves submitting this application as soon as your sale becomes firm, not waiting until after closing.

Processing Timeline and Planning

CRA currently takes six months or longer to process certificate applications, a significant increase from previous 30-60 day timelines. This extended processing period has important implications for your financial planning, especially if you need sale proceeds for another purchase.

During the processing period, your lawyer continues withholding tax using the default method. Once CRA approves your certificate, any excess withholding gets refunded. The lengthy processing time means you should factor this delay into your financial planning and consider whether the cash flow benefit justifies the effort. Requests for refunds of excess tax withheld must be filed within the specific calendar year following the sale, so be mindful of this deadline when planning.

Application for Individual Tax Number (T1261)

Before filing any Canadian tax forms, you need a Canadian tax identification number for income tax purposes. If you don’t have a Social Insurance Number (SIN), Temporary Taxation Number (TTN), or previously issued Individual Tax Number (ITN), you must apply for an ITN using Form T1261.

This application requires a certified copy of government-issued photo identification like a driver’s license or passport. The certification must be completed by a qualified professional such as a notary, lawyer, doctor, or chartered professional accountant. The certifying professional must include their official title, address, and contact information on the certified copy.

You can submit Form T1261 alongside your T2062 certificate application, but processing your ITN may add time to the overall process.

Acceptable Security for Non-Resident Sellers

If you are a non-resident selling U.S. property, you may be required to provide acceptable security to guarantee payment of any tax owing to the IRS. Acceptable security can include a bond, letter of credit, or other forms approved by the IRS, and is typically calculated as a percentage of the gross proceeds from the sale. To reduce the amount of withholding tax, non-resident sellers can apply for a withholding certificate, which allows for a lower withholding based on the actual tax liability rather than the gross sale price.

Obtaining a withholding certificate involves additional paperwork and may require the assistance of a tax professional, as the process can be complex and time-consuming. Ensuring you have the right acceptable security in place helps avoid unnecessary withholding and ensures compliance with U.S. tax rules for non-residents.

 

Reducing Non-Resident Withholding Tax on the Sale

Several strategies can help minimize your withholding tax and maximize your adjusted cost base—the foundation for calculating your taxable gain. These strategies are governed by the relevant Tax Act, which outlines the rules for withholding requirements and potential reductions for non-residents.

Maximizing Your Adjusted Cost Base

Your adjusted cost base includes your original purchase price plus qualifying capital improvements. Gathering documentation for all improvements is crucial, as these additions directly reduce your taxable gain.

Qualifying improvements include structural additions, major renovations, and capital improvements that add lasting value to the property. Keep receipts, invoices, and cancelled checks as supporting documentation. However, personal property like appliances doesn’t qualify for inclusion in your cost base.

Special Exemptions and Reductions

Principal Residence Exemption: If you were a Canadian resident during part of your ownership period and the property served as your principal residence, you might qualify for the Principal Residence Exemption using Form T2091. This exemption, provided under section 40(2)(b) of the Income Tax Act, can eliminate or significantly reduce your taxable capital gain.

Fresh Start Rule: U.S. residents who owned Canadian property on September 26, 1980, and sold after December 31, 1984, may benefit from Article XIII of the Canada-U.S. Tax Convention. This provision can reduce your capital gain by excluding appreciation that occurred before 1985. To qualify, you need proof of continuous U.S. residency from September 26, 1980, to the sale date, plus a professional appraisal of the property’s value on December 31, 1984.

Tax Treaties and Agreements

Canada has established tax treaties and agreements with many countries, including the United States, to help avoid double taxation and clarify tax liabilities for cross-border transactions. The Canada-U.S. tax treaty is particularly important for Canadian residents selling U.S. property, as it provides mechanisms for claiming tax credits and reducing U.S. tax liability. The treaty outlines how income such as wages, pensions, and capital gains should be taxed by each country, helping to prevent the same income from being taxed twice.

Understanding the tax treaty and its implications is essential for minimizing your overall tax liabilities and ensuring you take advantage of available tax credits and deductions. Canadians selling U.S. property should consult a professional advisor familiar with cross-border tax issues to ensure compliance with both U.S. and Canadian tax laws and to optimize their tax position.

Filing a Canadian Tax Return

After completing your property sale, you must file a Canadian income tax return (Form T1) to report the disposition. The gain from the sale must be reported for Canadian income tax purposes. You are required to report the sale in the tax year in which the disposition occurred. This requirement exists regardless of whether you obtained a Certificate of Compliance.

Recovering Excess Withholding

In most cases, the withholding tax exceeds your actual tax liability on the capital gain. Several factors contribute to this over-withholding:

  • Selling costs (legal fees, real estate commissions, accounting fees) reduce your taxable gain but aren’t considered in the withholding calculation
  • The 35% withholding rate often exceeds the effective tax rate on capital gains
  • Additional deductions or exemptions may apply when filing your return

Filing your Canadian tax return typically results in a refund of excess tax withheld, making this step financially beneficial beyond mere compliance.

Rental Property Considerations

If your property generated rental income while you were a non-resident, you face additional compliance requirements. Non-residents must report both gross rental income and net rental income on their non resident tax return. Filing a non resident tax return is required to comply with Canadian tax laws regarding rental income. You should have been filing annual Canadian tax returns and remitting monthly withholding tax on rental income throughout your ownership period.

Unreported rental income must be addressed before obtaining a Certificate of Compliance. Consider voluntary disclosure if you haven’t been compliant with rental income reporting, as this approach can minimize penalties and interest charges.

Avoiding Penalties & Becoming Compliant

Late filing penalties for Certificate of Compliance applications are $25 per day, with a minimum penalty of $100 and maximum of $2,500 per non-resident owner. While these penalties might seem manageable, the bigger issue is the extended withholding period and potential complications with your sale closing. Non-residents should also be aware of potential state taxes that may apply to their property sale, as state tax obligations can vary depending on the property’s location.

Preparing Required Documentation

Success with your Certificate of Compliance application depends on having complete documentation ready before you need it for the sale of real property. Essential documents include:

  • Original purchase agreement and closing statements
  • Title documentation proving current ownership
  • Current sale agreement
  • Receipts and invoices for all capital improvements
  • Rental income records (if applicable)
  • Previous tax returns (if you’ve filed any Canadian returns)

Professional Assistance Timeline

Given the complexity of Canadian tax rules for non-residents and the tight 10-day filing deadline, professional assistance is virtually essential. Engage qualified Canadian tax professionals well before your anticipated closing date—ideally when you first decide to sell, not when you accept an offer. It is highly recommended that non-residents seek professional advice to ensure compliance with all regulations and to optimize their tax position.

Professional fees for Certificate of Compliance applications and tax return preparation typically start around $4,000 CAD, but the potential savings in reduced withholding tax often justify this investment many times over.

Planning Your Property Sale Successfully

Selling Canadian property as a non-resident requires careful planning and attention to detail, but the financial benefits of proper compliance far outweigh the complexity. Foreign investment in Canadian real estate by non-residents has specific tax implications. By understanding your obligations and taking proactive steps, you can minimize withholding taxes, ensure compliance, and often recover significant amounts through your tax return filing.

Start gathering your documentation early, engage qualified Canadian tax professionals before listing your property, and factor the extended processing times into your financial planning. Canadians pay taxes on gains from the sale of U.S. property, and the buyer’s intended use of the property—such as whether the buyer intends to occupy it as a residence—can affect withholding requirements. With proper preparation, you can navigate this process successfully while protecting your financial interests.

Remember that tax rules and processing times continue to evolve, so working with experienced Canadian tax professionals ensures you have current information and optimal strategies for your specific situation.
