Selling US Real Estate as a Canadian: What You Need to Know Before You List

Jared Pilon

If you own property in the US, whether it is a vacation home in Arizona, a rental condo in Florida, or an investment property in California, you may face the decision to sell. While selling real estate is already complex, doing so as a Canadian with US property introduces layers of tax reporting and compliance requirements that can catch even the most prepared owners off guard.

With the right knowledge and planning, you can successfully navigate this process and avoid costly mistakes. Here's what you need to know before you put the "For Sale" sign up.

Understanding the Three Levels of Tax Reporting

When you sell US property as a Canadian, you deal with three distinct levels of tax reporting, each with its own requirements and deadlines.


Level 1: US Federal Tax Obligations

First and foremost, you need to file a US tax return reporting the sale. This means completing Form 1040-NR (the non-resident tax return) and paying capital gains tax to the IRS on any profit from the sale.
Before you receive your proceeds, you should be aware of FIRPTA, or the Foreign Investment in Real Property Tax Act. Under FIRPTA, the buyer is required to withhold 15% of the gross sale price and remit it directly to the IRS as a prepayment of your potential tax liability. 
For example, if you sell a property for $500,000, the buyer must withhold $75,000 and send it to the IRS, even if your actual tax liability is much lower. You need to file a US tax return to claim any refund owed to you.


Level 2: State Tax Requirements

Depending on which state your property is located in, you may also face state-level tax obligations. Many states have their own withholding requirements and filing deadlines, which may differ from federal rules.
Some states are more aggressive than others in collecting taxes from non-residents. Determine whether the state requires a separate tax return and what withholding applies. This is not a one-size-fits-all situation. Each state has its own rules.


Level 3: Canadian Tax Reporting

Finally, you need to report the sale to the Canada Revenue Agency (CRA). Even though you've already paid US taxes on the gain, you must also report it on your Canadian tax return.

The good news is that Canada and the US have a tax treaty designed to prevent double taxation. You can claim a foreign tax credit for the US taxes you've paid, which will offset your Canadian tax liability. However, you still need to properly report the transaction.

Ensure your Form T1135 (Foreign Income Verification Statement) is up to date if the cost of your foreign property exceeds $100,000. This form tracks your foreign assets and is required annually (if the property held is used for anything other than strictly personal use, not just in the year of sale.

Common Pitfalls to Avoid

Underestimating FIRPTA Withholding

Many Canadians are shocked when 15% of their sale proceeds are withheld. If you count on that money for your next purchase or investment, this can create cash flow problems. Plan ahead. You may not see that money until you file your US tax return and receive your refund, which can take months.

Ignoring State Requirements

It is easy to focus on federal obligations and overlook state taxes. Do not assume that because you've filed with the federal government, you are done. Research the specific requirements for the state where your property is located, or work with an advisor who can guide you.

Missing Filing Deadlines

Each level of reporting has its own deadline. Missing a US filing deadline can result in penalties and interest, while failing to report on your Canadian return can trigger CRA scrutiny. Stay organized and work with professionals who understand cross-border tax obligations.
 

Failing to Track Adjusted Cost Base

To accurately calculate your capital gain, you need to know your adjusted cost base, which includes the original purchase price plus any capital improvements you've made over the years. Keep detailed records of renovations, additions, and major repairs. Without proper documentation, you may end up paying tax on a larger gain than you actually realized.

The Value of Professional Guidance

You should not tackle the sale alone. The interplay between US federal tax, state tax, and Canadian tax rules is complicated, and the stakes are high. 

Working with a cross-border tax specialist ensures that you:

  • Understand your withholding obligations before closing
  • File all required returns accurately and on time
  • Maximize your foreign tax credits to avoid double taxation
  • Maintain compliance with both US and Canadian tax authorities
