Sell a residential property in Canada after owning it for less than 365 days and the CRA's anti-flipping rule deems your entire profit to be business income: 100% taxable, with no capital gains rate and no principal residence exemption. The rule has applied to sales since January 1, 2023, and it extends to assignment sales of pre-construction homes and condos. A short list of life events can exempt you. Everyone else, including real estate agents who flip on the side, pays full tax on every dollar.
What is the CRA's residential property anti-flipping rule?
The residential property flipping rule is a deeming rule in the Income Tax Act that applies to dispositions on or after January 1, 2023. A "flipped property" is a housing unit located in Canada, including a rental property, or a right to acquire one, that you owned or held for less than 365 consecutive days before selling, unless the sale is caused by one of the life events listed below. Property you already hold as business inventory is outside the definition because it is fully taxable anyway.
If your sale is caught, three things happen:
- The full gain is business income. There is no 50% capital gains inclusion, no matter what your intentions were when you bought.
- The principal residence exemption is unavailable. Living in the property does not help if you owned it for less than a year.
- A loss is deemed to be nil. If the market moves against you and you sell at a loss within 365 days, you cannot claim it.
The rule is not limited to individuals. It applies to corporations and trusts too, so routing a quick flip through a company does not sidestep it.
How much more tax do you pay when a sale counts as a flip?
The capital gains inclusion rate in Canada is 50% in 2026. The proposed increase to two-thirds was cancelled in March 2025 and never became law, so a capital gain still gets half of the profit tax-free. A flip gets nothing.
Run the numbers on an $80,000 profit for someone with a 45% marginal tax rate. As a capital gain, $40,000 is taxable and the bill is about $18,000. As business income under the flipping rule, all $80,000 is taxable and the bill is about $36,000. If you were counting on the principal residence exemption, the swing is even worse: $0 of tax versus $36,000.
| Treatment | Capital gain | Flipped property (business income) |
|---|---|---|
| Portion of profit taxed | 50% | 100% |
| Principal residence exemption | Available if you qualify | Denied |
| Selling at a loss | Capital loss, usable against capital gains | Loss deemed nil |
| Where it is reported | Schedule 3 | Form T2125 as business income |
| GST/HST exposure | Used housing generally exempt | Can apply to renovated homes and assignments |
The CRA's capital gains guide (T4037) covers the flipped property rules alongside the normal capital gains regime.
Which life events exempt a sale from the 365-day rule?
The deeming rule does not apply if the sale can reasonably be considered to occur because of, or in anticipation of, one of these events:
- The death of the taxpayer or a related person
- A related person joining your household, or you joining a related person's household (a new child, or a parent moving in, for example)
- The breakdown of a marriage or common-law partnership, where you have lived separate and apart for at least 90 days before the sale
- A threat to the personal safety of you or a related person
- A serious illness or disability of you or a related person
- An eligible relocation of you or your spouse or common-law partner (generally, a move that lets you work at a new location or attend full-time post-secondary school, with the new home at least 40 kilometres closer)
- Involuntary termination of employment of you or your spouse or common-law partner
- Insolvency
- Destruction or expropriation of the property
Two warnings. First, document the event: a separation agreement, a job termination letter, medical records. The CRA will ask. Second, qualifying for an exception only turns off the automatic deeming. The CRA can still tax the profit as business income under ordinary principles if the facts show you bought to resell.
Can the CRA tax you as a flipper even after 365 days?
Yes. The 365-day rule is a floor, not a safe harbour. Holding for 366 days does not convert a flip into a capital gain. The CRA's long-standing position, backed by decades of case law, looks at your intention when you bought, how the purchase was financed, your occupation and knowledge of real estate, how often you buy and sell, the work you did on the property, and why you sold. A renovator who buys, guts and lists a house every 14 months is still running a business, and the profit is still 100% taxable. The anti-flipping rule simply removed the argument for anything sold inside a year.
How are assignment sales taxed?
Income tax: the 12-month clock applies to the paper, not just the house
Since January 1, 2023, the flipping rule also covers assignment sales, which the CRA describes as "shadow flipping." If you assign your rights under a purchase agreement after holding those rights for less than 12 months, the profit is deemed business income. And the clock resets when the property closes: hold a pre-construction contract for three years, take title, then sell four months later, and that sale is still a flip because your ownership of the completed unit lasted less than 365 days.
GST/HST: every assignment of a new home is taxable
Since May 7, 2022, all assignment sales of newly constructed or substantially renovated housing are taxable for GST/HST purposes, even one-off assignments by individuals. The assignor is generally responsible for collecting and remitting the tax; if the assignor is a non-resident, the assignee must self-assess. One planning point: if the assignment agreement states in writing that part of the price reimburses the deposit you paid the builder, that deposit portion is excluded from the taxable amount. The CRA's guide GI-120 on assignments of purchase and sale agreements walks through the mechanics.
Do you owe GST/HST when you sell a renovated flip?
Sales of used residential housing are generally GST/HST-exempt. But if you substantially renovate a home in the course of a business, meaning all or substantially all of the interior is removed or replaced, you can be treated as a builder, and the sale becomes taxable like a new home. On a $700,000 sale in Ontario, that is $91,000 of HST you did not budget for. Anyone doing gut renovations for resale should price GST/HST into the deal before making an offer, not after closing.
Why are real estate agents a prime audit target on flips?
The CRA's own guidance on property flipping explicitly names real estate agents. The logic is simple: agents see deals first, understand market values, and can move quickly, so the CRA assumes an agent's flip is business activity almost by default. Agents also leave a rich data trail. The CRA cross-references land registry records, MLS data, your commission income and your GST/HST filings, so a quick resale rarely goes unnoticed. If you flip through a PREC, the profit is active business income inside the corporation, and the anti-flipping rule reaches corporations anyway. Our PREC accounting guide for Ontario covers how property profits interact with your corporate structure, and if you earn commission income you should also understand how HST applies to real estate commissions in Ontario. SNF's accounting service for real estate agents handles both sides: your commission business and your property deals.
Is there a provincial flipping tax too?
British Columbia layers its own home flipping tax on top of the federal rules. Effective January 1, 2025, BC taxes 20% of the net income from a taxable property sold within 365 days, with the rate tapering to zero once you have owned the property for 730 days. It applies to presale contracts as well. If you flip in BC, you budget for both the federal business-income treatment and the provincial tax.
Frequently Asked Questions
Does the anti-flipping rule apply if I lived in the home as my principal residence?
Yes, if you owned it for less than 365 days and no life-event exception applies. The rule specifically denies the principal residence exemption for flipped property, so genuinely moving in does not protect a quick resale. If your sale within the year was triggered by a listed event, such as a job relocation, separation after 90 days apart, or serious illness, the deeming rule does not apply and normal principal residence rules can still shelter the gain. Keep evidence of the event.
What happens if I lose money on a property I sell within 365 days?
The loss is deemed to be nil. This is the harshest edge of the rule: a flipper who profits pays tax on 100% of the gain, but a flipper who loses money gets no deduction at all, neither as a business loss nor as a capital loss. Someone forced to sell in a falling market within a year should check the life-event exceptions carefully, because qualifying for one restores normal tax treatment, including the ability to claim a loss.
Do I have to charge GST/HST when I assign a pre-construction condo?
Yes. Since May 7, 2022, every assignment sale of a newly constructed or substantially renovated home is taxable for GST/HST, even if you are an individual making a single assignment. You are generally responsible for collecting and remitting the tax on your assignment profit, though an amount identified in writing as reimbursing your builder deposit is excluded. On top of that, your assignment profit is normally business income for income tax if you held the rights for under 12 months.
If I own a property for more than 365 days, is the profit automatically a capital gain?
No. Passing the 365-day mark only means the automatic deeming rule does not apply. The CRA can still assess the profit as fully taxable business income based on the traditional factors: your intention at purchase, your occupation, how often you trade properties, the renovation work done, the financing used and the reason for selling. Serial renovators and real estate professionals are routinely assessed as earning business income on properties held well past one year.
Does the flipping rule apply to corporations and PRECs?
Yes. The flipped property rule applies to individuals, corporations and trusts, so holding a quick flip inside a corporation or a PREC does not avoid it. Inside a corporation the profit is active business income, and the corporation may also face GST/HST obligations if the property was substantially renovated or assigned. For agents, a flip inside a PREC also affects how much you can pay yourself as salary or dividends, which is worth modelling before the sale, not at year-end.
