Canada’s Anti-Flipping Rule: The 365-Day Tax Trap and How to Avoid It (2026)

If you sell a residential property within 365 days of buying it, the profit is taxed as business income, not as a capital gain. Business income is fully taxable at your marginal rate. There is no 50% inclusion rate, no capital gains exemption, and no principal residence exemption. On a $100,000 profit in Ontario at the top marginal rate of 53.53%, that is $53,530 in tax instead of roughly $26,765 under capital gains treatment.

The anti-flipping rule took effect January 1, 2023, under ITA section 12(13). At our firm, we have worked with clients who were caught off guard by this rule after selling a property they had renovated and flipped within a year. The tax bill was double what they expected. This post walks through how the 365-day rule works, every exemption the CRA recognizes, how assignment sales are treated, and what legitimate renovators and investors can do to plan around it.

How the 365-Day Rule Works

The rule is mechanical. If you dispose of a residential property (or a right to acquire one, such as an assignment sale) and you owned it for fewer than 365 consecutive days, the profit is deemed to be business income. The CRA does not consider your intentions. The holding period is the only test.

Under ITA section 12(13), the “flipped property” rules apply to housing units, including houses, condos, townhouses, duplexes, and cottages. The clock starts on the day you acquire the property (closing date) and runs to the day you dispose of it (sale closing date). A property bought on March 15, 2026 and sold on March 14, 2027 has been held for 365 days and is outside the rule. Sold on March 13, 2027? That is 364 days, and the rule applies.

The rule overrides any other characterization. Even if you lived in the property as your primary home, even if you intended to keep it for 10 years, if you sell within 365 days and no exemption applies, the profit is business income.

The profit subject to business income treatment is calculated as the sale price minus your cost (purchase price plus closing costs, legal fees, land transfer tax, and renovation costs). You report it on line 13500 of your T1 return as other income, not on Schedule 3 as a capital gain.

The Exemptions: When the Rule Does Not Apply

The rule includes a list of exemptions under ITA subsection 12(14) for life events that force a sale within 365 days. If you qualify for an exemption, the normal capital gains rules apply and you may also claim the principal residence exemption if the property was your primary home.

Here are the recognized exemptions:

Death. If the property is sold because the owner or their spouse died, the rule does not apply. This includes the estate selling the property and a surviving spouse selling after inheriting.

Addition to the household. The birth of a child, adoption, or a new family member moving into the household qualifies if the current home cannot accommodate the larger household. The CRA expects a genuine space constraint, not a preference for a larger home.

Separation or divorce. A breakdown of a marriage or common-law partnership qualifies. The CRA does not require a court order. A genuine separation where the partners are living apart and at least one needs to sell the shared property is sufficient.

Personal safety threat. If the property is sold because of a threat to the personal safety of the owner or a related person (domestic violence, harassment, stalking), the exemption applies.

Serious illness or disability. A previously undiagnosed illness or disability that requires a move to a more accessible property or closer to medical care qualifies.

Employment relocation. If you or your spouse start a new job, or are transferred by your current employer, and the new workplace is at least 40 kilometres closer to the new home than the old home (measured by the shortest public route), the sale qualifies. This is the same 40 km test the CRA uses for moving expense deductions under ITA section 62.

Insolvency. If the sale is required to satisfy creditors or avoid bankruptcy, the exemption applies.

Involuntary disposition. Expropriation, destruction (fire, flood), or condemnation by a government authority. The property was lost, not sold by choice.

In each case, the exemption only applies if the sale is related to the qualifying event. Selling a rental property because you got a new job 200 km away does not qualify. The employment relocation exemption applies to a home you were living in, not an investment property.

At Tohme Accounting, we review every property sale under 365 days against this list. Some clients qualify for an exemption and do not realize it. Others assume they qualify but do not meet the specific conditions. If you sold a property within a year and are not sure whether an exemption applies, contact our team before filing.

Assignment Sales and Pre-Construction Condos

The anti-flipping rule applies to assignment sales. An assignment is when you sell your right to purchase a pre-construction property before closing. You never take title. You are selling the purchase agreement itself, and any profit is subject to the 365-day test.

The 365-day clock for assignment sales starts when you entered into the original purchase agreement, not when the building was completed. If you signed a purchase agreement for a pre-construction condo in January 2025 and assigned that agreement in June 2025, that is fewer than 365 days and the profit is business income.

Assignment sales also attract HST in Ontario. Under ETA subsection 123(1), an assignment of a residential purchase agreement by an individual who is not a builder is a taxable supply. The assignor must collect and remit 13% HST on the profit (the assignment fee), unless they can demonstrate the assignment was an exempt supply because they originally intended to use the property as a primary residence.

The HST exposure adds a second layer of cost. A $50,000 profit on an assignment sale within 365 days means $50,000 taxed as business income (up to 53.53% in Ontario) plus $6,500 in HST, for a combined tax bill that can exceed 65% of the profit.

Pre-construction investors in Toronto and Ottawa need to plan the holding period carefully. If you entered a purchase agreement with a builder and the building timeline shifts, the 365-day window may close before you expected. Our team works with real estate investors to structure the timeline and documentation so the holding period and tax treatment are clear before a sale decision is made.

Business Income vs Capital Gains: What Is at Stake

The financial difference between business income and capital gains treatment is substantial. Here is a comparison at three profit levels for an Ontario taxpayer in the top bracket:

Capital gains above $250,000 now have a two-thirds inclusion rate (effective June 25, 2024). For gains between $250,001 and above, the capital gains rate is higher than the traditional 50% inclusion, but still lower than the 100% inclusion of business income.

There is another cost that people overlook: the principal residence exemption. If you sell your primary home within 365 days and no exemption applies, you cannot use the PRE to shelter the gain. The PRE only applies to capital gains, not business income. A home that would have been completely tax-free under the PRE becomes fully taxable.

If you are considering selling a property and you are within or close to the 365-day window, it is worth talking to a CPA before listing. The tax difference between selling on day 364 and day 366 can be tens of thousands of dollars. Our team at Tohme Accounting helps clients in this situation time their sales and document their circumstances to support the correct tax treatment.

Provincial Tax Layers on Top of the Federal Rule

The anti-flipping rule is federal, but several provinces add their own real estate tax measures that can stack on top of it.

Ontario. The Non-Resident Speculation Tax (NRST) is 25% of the purchase price for non-Canadian buyers (expanded from 15% in 2022). This applies at the time of purchase, not sale, but it affects the economics of flipping for non-resident investors. Ontario also charges land transfer tax on every purchase, plus an additional municipal land transfer tax in Toronto (roughly 2-3% combined on a $700,000 property). These are sunk costs that reduce the profitability of a short-term flip.

British Columbia. The Speculation and Vacancy Tax (SVT) applies in designated areas (Metro Vancouver, Victoria, Kelowna, and others) to property owners who do not occupy their homes or rent them out. The SVT rate is 2% of the assessed value for foreign owners, 0.5% for Canadian citizens who are not BC residents, and 0.5% for certain other categories. BC also has a Foreign Buyer Tax of 20% in designated areas.

Federal vacancy tax. The Underused Housing Tax (UHT) applies a 1% annual tax on the value of vacant or underused residential property owned by non-Canadian, non-permanent-resident owners (and certain Canadian entities). This is separate from the anti-flipping rule but adds to the cost of holding property short-term without occupying it.

A non-resident investor who buys a Toronto condo for $600,000, pays 25% NRST ($150,000), pays land transfer tax ($16,475), flips it in 8 months for $700,000, and triggers the anti-flipping rule faces business income tax on the $100,000 profit at their marginal rate. Combined with the sunk costs, the net result can be a loss after tax.

Planning for Legitimate Renovators and Investors

If your business involves buying, renovating, and selling properties, the anti-flipping rule does not change your tax treatment. Property flipping as a business was already taxed as business income before 2023. The rule targets individuals who sell one-off properties within a year and try to report the gain as a capital gain.

For investors who buy, renovate, and hold, the 365-day rule is a planning constraint, not a barrier. Here are approaches we discuss with our real estate clients:

Hold past 365 days. If you are renovating a property and the work takes 10 months, waiting two more months before listing costs you some carrying expenses (mortgage interest, property tax, insurance) but may save you tens of thousands in tax. Run the numbers.

Rent the property. If you complete renovations and the market timing is not ideal, renting the property generates income while the clock runs. A property that is rented for 6 months after renovation and then sold after 400 days gets capital gains treatment (assuming the CRA accepts that your intention was to hold it as a rental, not to flip).

Incorporate the flipping business. If you flip multiple properties per year, incorporating and running the operation as a business gives you access to the small business corporate tax rate of 12.2% on the first $500,000 of active business income. The income is still business income, but the corporate rate is lower than personal marginal rates. You pay personal tax when you withdraw funds from the corporation. Our sole proprietorship vs incorporation guide covers the math.

Document your intention at purchase. If you buy a property intending to hold it long-term but circumstances change within 365 days (a qualifying exemption), keep records that support your original intent. Board meeting minutes if incorporated, loan terms showing long-term financing, renovation plans that imply a multi-year timeline. These records matter if the CRA questions the exemption claim.
