Residential Property Flipping Rule: What the 12-Month Rule Actually Means

Key takeaways

• Properties sold within 12 months of acquisition are automatically treated as business income — not capital gains
• The principal residence exemption cannot be used to shelter gains on flipped properties
• Several life-event exemptions apply: death, disability, breakdown of a relationship, involuntary job loss, and others
• The rule applies to residential property purchased on or after January 1, 2023
• New construction and assignment sales are also subject to the rule under certain conditions

The Residential Property Flipping Rule, which took effect January 1, 2023, was introduced to address a practice the government believed was contributing to housing unaffordability: rapid speculative buying and selling of homes. The rule creates a deemed business income inclusion for any property sold within 12 months of purchase — overriding the capital gains treatment and principal residence exemption that might otherwise apply.

How the rule works

If you sell a residential property within 12 months of the day you acquired it, the entire gain is treated as business income — not a capital gain. This means: no 50% (or two-thirds) inclusion rate applies; the full gain is added to your income; the principal residence exemption cannot be claimed; and ordinary income tax rates apply to 100% of the profit.

The rule is mechanical — it does not depend on your intention or whether you are in the business of flipping properties. Buying a house and selling it 11 months later because you received an unexpected job offer would still trigger the rule (absent an applicable exemption).

The 12-month clock

The 12-month period runs from the date of acquisition (when the title or beneficial ownership transferred to you) to the date of disposition (when you transferred title or beneficial ownership to the buyer). The contract date matters for some purposes, but the title date is the relevant date for the flipping rule.

If you bought a pre-construction condo and assigned the agreement before closing, the assignment itself may trigger the rule if the assignment occurs within 12 months of signing the purchase agreement. The CRA's position is that the "acquisition" date for pre-construction is generally the date of the original purchase agreement.

The exemptions

The Income Tax Act lists specific exceptions where the 12-month rule does not apply. These are narrowly defined and require documentation. The main exemptions are: death of the owner or a related person; serious illness or disability; breakdown of the marriage or common-law partnership (separation or divorce); eligible involuntary job relocation (the new work location must be at least 40 km closer to the new home); and involuntary disposal under threat of expropriation.

The exemption for relationship breakdown requires that the spouses or partners be living separate and apart due to a breakdown in the relationship — the property sale must occur as part of the settlement. A couple who decides to sell and split the proceeds for unrelated reasons while still together does not qualify.

There is no exemption for financial hardship, a better investment opportunity, or a change in personal preference. The exemptions are genuinely narrow.

Planning considerations

If you are purchasing a residential property and there is any possibility you might need to sell within 12 months, be aware of the rule going in. Twelve months and one day past the acquisition date, you are back to standard capital gains treatment (subject to the principal residence exemption if you lived there as your principal residence).

For builders and renovators who regularly buy, improve, and sell properties — the flipping rule may be largely irrelevant because gains were already being reported as business income under the general business activity rules. The flipping rule primarily changes the treatment for casual sellers who bought and sold quickly without being in the business of real estate.
