Property Flipping in Canada: The 12-Month Rule That Removes Your Choice

Before 2023, whether a quick property sale produced a capital gain or business income was a question of fact, argued on intention and circumstances. Taxpayers frequently won.

That argument is largely closed for short holds. The residential property flipping rule deems the profit to be business income where a residential property is sold within twelve months, regardless of what you intended.

What the rule does

Where you dispose of a residential housing unit in Canada, or a right to acquire one, that you held for less than 365 consecutive days, the gain is deemed business income.

Two consequences, both severe:

The denial of the principal residence exemption is what people miss. Live in the property, make it genuinely your home, sell at month ten: the exemption does not apply. The rule overrides it.

Assignment sales are caught. Selling a right to acquire a property, a pre-construction assignment, is within the rule.

The exceptions, which are life events

A property is not a flipped property where the disposition can reasonably be considered to occur because of, or in anticipation of, a defined list of events:

• Death of the taxpayer or a related person
• A related person joining the household, or the taxpayer joining theirs
• Breakdown of a marriage or common-law partnership, where you have lived separate and apart for at least 90 days
• A threat to personal safety, such as domestic violence
• Serious illness or disability of the taxpayer or a related person
• An eligible relocation, meeting the distance test used for moving expenses
• Involuntary termination of employment
• Insolvency
• Destruction or expropriation of the property

Note the framing. These are genuine changes in circumstance, not planning opportunities. “I decided to move closer to work” is not an eligible relocation unless it meets the distance test.

Document the event at the time: a separation agreement, a termination letter, medical records, a relocation offer. The exception is a factual claim and you will be asked to support it.

Twelve months is not the whole story

Surviving the 365 days does not make the gain a capital gain. It means the deeming rule does not apply automatically. The original question returns, and the CRA weighs the ordinary factors:

• Intention at purchase. Bought to live in, to rent, or to resell?
• Frequency of similar transactions. A pattern is powerful evidence
• Nature of the work done. Substantial renovation aimed at resale points one way
• Length of ownership. Thirteen months is not obviously different from eleven
• Financing. Short-term or high-cost financing suggests a resale plan
• Your occupation. A realtor or builder faces a harder argument

Someone selling their third property in four years at month fourteen each time is not protected by the calendar.

Where this catches ordinary people

Pre-construction condos. Assign the contract before closing and you are inside the rule. Many buyers treat an assignment as capital. It is not.

Buy, renovate, move in, sell. Genuine occupancy does not help inside twelve months.

Inherited property sold quickly. Death is an eligible exception, but the analysis depends on whose death and the relationship. Check rather than assume.

A rental bought and resold quickly. The rule is not limited to homes you lived in. It covers residential property generally, including rentals.

GST/HST, the second bill

Often missed, and on new housing it is not a judgment call at all.

Assignments are taxable outright. The CRA states that effective 7 May 2022, all assignment sales in respect of newly constructed or substantially renovated residential housing are taxable for GST/HST purposes. So a pre-construction assignment is caught twice: business income under the flipping rule, and GST/HST on the assignment consideration. The assignor is often the one who has to charge and remit it, which is a surprise to someone who thought they were simply selling a contract.

The new housing rebate may have to go back. The GST/HST new housing rebate depends on acquiring the home with the intention that you or a relation occupy it as a primary place of residence. Buy new, never move in, resell inside a year, and the intention the rebate rested on is difficult to defend. The rebate is frequently credited by the builder at closing, so repaying it means finding cash years after the money was spent. The conditions are in the HST new housing rebate.

A resale property can become newly taxable. A substantial renovation puts a previously occupied home back into the new-housing rules on sale, which is exactly what a serious flip involves. Someone doing this with any regularity may also be carrying on a business for GST/HST purposes and required to register. See GST/HST registration.

If the rule applies to you

It is not the end of the world, and it changes what you can claim.

Business income means expenses are deductible against it: renovation costs, interest, property taxes and utilities during the hold, realtor commissions, legal fees. Those reduce the amount taxed.

It also means you should have been tracking those costs from the beginning. Most people who discover the rule applies discover it after the receipts are gone.

What it does not give you is symmetry. The deeming rule is written about profit. Where a short hold produces a loss, you cannot assume the same provision hands you a fully deductible business loss to set against employment income, and a loss on a property that was genuinely your home is a personal-use loss that is denied outright. Model the downside on the assumption that the treatment is worse than the mirror image of the upside.

A property you have been renting out before the sale raises a further question, because the rental years and the sale can be characterised differently. The distinction is set out in rental income versus business income, and if the use changed at any point, change of use applies on top.

Where the rule does not apply, the sale is a capital gain and the levers are entirely different ones: which years the exemption is designated against, how well the cost base is documented, and which tax year the deal closes in. Those four decisions are all made before the listing rather than after the offer.

What to do before you buy

1. Decide honestly what this is. A home, an investment, or a project. That determines the treatment more than anything you write down later
2. If resale is contemplated, plan for business income and track every cost from day one
3. If it is genuinely your home, hold past 365 days unless a listed life event intervenes
4. Document any life event contemporaneously if you must sell early
5. Report the sale. Dispositions are visible to the CRA through land registry data, and unreported ones are a stated compliance priority

Whether the gain lands as business income or a capital gain changes the return rather than the transaction, so the reporting position is best settled with whoever is filing that year for you.

If you have a property you may need to sell inside a year, or you already have and are unsure how to report it, resolve it before you file rather than after a reassessment.
