Politicians are constantly searching for new tax revenue. Not wanting to upset national residents and ultimately voters, officials often include non-voting, foreign owners of domestic property as a key component to increasing tax revenue.
Canadian Snowbirds who own real estate in the U.S. are prime candidates for paying increased taxes. Since the taxation rules are complicated and can change frequently, it is vital to stay informed and in-the-know.
What you Need to Know
To be exempt from filing IRS forms or a U.S. tax return, all three conditions must be met:
- You do not earn any U.S. source income (interest, dividends, capital gains, rent) and
- You are not physically present in the U.S. for more than 182 days and
- You score less than 183 on the Substantial Presence Test:
- To calculate your Substantial Presence score, add together
- Number of days spent in the U.S. in the current tax year
- One-third of the days spent in the U.S. from the prior tax year
- One-sixth of the days spent in the U.S. the year prior to that
- An example:
- To calculate your Substantial Presence score, add together
2021: Days in U.S. = 140 x 1 = 140
2020: Days in U.S. = 93 x 1/3 = +31
2019: Days in U.S. = 120 x 1/6 = +20
Your Substantial Presence Score = 191
These calculations can be further complicated by the fact that the IRS follows the calendar year, and typically Snowbirds stay six to eight weeks in one year and then another eight weeks or more in January, February and March of the following year. Retaining airline tickets or toll receipts easily satisfies the information requirements of the IRS.
Additionally, it is important to understand the IRS’ definition of ‘day.’ The IRS counts any time spent during a calendar day, as a full day. If, for example, you cross into the U.S. at 11:55 pm, and return ten minutes later at 12:05 am, the IRS would consider this 10-minute trip as two full days since you spent time during two different calendar days, even though it was only five minutes in each. This is an extreme example but remember there are no half-days!
Also, important to note that the IRS includes all visits to the U.S. throughout the year, not just your winter snowbird holiday. Daytrips for shopping or sporting events, for example, must also be included in your Substantial Presence calculations and determination of total days in the U.S.
If you frequently travel to and from the U.S, you may want to keep a small journal in your car where you can write down the date, time, and occupants for each time you enter and exit the United States. Currently, a credible journal is sufficient proof for the IRS.
Point #1, above, addressing U.S, source income is not as straight-forward as it sounds. If the income is ‘rent’, then a 1040-NR (Non-Resident tax return) may be necessary.
Interest income is ‘zero-rated’ for Canadians, so technically the income should be declared, but the tax rate is zero, so no U.S. tax is levied.
U.S. dividends are taxed at a flat rate of 15% for Canadians, and if the proper filings are made from your broker (either Canadian or U.S. based) to the company paying the dividends, then the 15% should be withheld at source. This withholding, along with U.S. income, is included on Canadian tax filings.
If the capital gain is the sale of the U.S. real estate, it is best to consult a Canadian-based U.S. tax expert before you contemplate selling to anticipate the necessary steps to repatriate your capital to Canada.
Further complicating the declaration of income is converting U.S. payments to Canadian dollars. The requirement is that the Bank of Canada exchange rate for the date of the transaction be used. If multiple payments occur, an average annual exchange rate from the Bank of Canada is acceptable to CRA.
There is no need to travel to an IRS office as all documents can be found at irs.gov

Some Key Factors to Know
- Canadians who earn U.S. source income subject to U.S. tax must file a U.S. tax return using IRS form 1040NR (non-resident).
- When U.S. property is sold by a foreign owner, the buyer is required by law to withhold ten percent of the purchase price and remit it to the IRS when the transaction is “closed”.
- The buyer’s lawyer withholds the 10%, because if it is overlooked, the IRS could require the buyer or the buyer’s lawyer to remit it while taxes are calculated
- Filing an 8288-B can reduce this 10% withholding amount all the way down to the anticipated tax amount, even if the tax is zero
- To file an 8288-B, a Tax Identification Number (TIN) like a U.S. Social Security Number or Canadian Social Insurance Number is needed
- Obtaining a TIN requires 6 to 8 weeks, and must be in-hand prior to contract signing to reduce the 10% withholding amount
- To file an 8288-B, a Tax Identification Number (TIN) like a U.S. Social Security Number or Canadian Social Insurance Number is needed
- If a Canadian stays in the U.S. for 183 days or more, they must file a full return or a non-resident return (1040-NR). Staying in the U.S. for 183 days or more makes the Substantial Presence Test and closer-connection criteria moot.
- If your Substantial Presence Score is over 182, file an 8840 form to prove that you have a ‘closer connection’ to Canada, since any person can only have one official home country at any given time it is usually simplest for “Canadians” to be tax residents of Canada.
Bottom Line
If you are a Snowbird or travel abroad often or for extended periods, you should consider and know the tax implications of your travel plans on your taxes in both the United States and in Canada. Although a tax treaty exists between the two countries, the tax laws are not identical.
In the U.S. details change often. Staying in touch with your Advisor will help you understand these issues. Ultimately, an accountant with a specialty in cross-border tax will provide the advice you require tailored to your situation.
