Holding for 366 Days Doesn't Make Your Flip a Capital Gain

“Just hold it a year and it's a capital gain.” That is not what the rule says.

It is the most repeated piece of advice in Canadian flipping, and it comes from misreading a single number.

The federal Residential Property Flipping Rule uses 365 days. People hear that and conclude that day 366 flips a switch: business income before, capital gain after. The CRA does not say that, and the difference is worth six figures on a good year.

What the 365-day rule actually is

It is a deeming rule. Introduced in Budget 2022 and applying to transactions on or after 1 January 2023, it says that if you owned a housing unit in Canada for fewer than 365 consecutive days, the profit is business income. Full stop. No argument about what you intended.

That is the entire job it does. It removes the debate inside the first year.

What happens after day 365

Here is the CRA's own language for what happens when the deeming rule does not apply, whether because you held it long enough or because a life event applied:

It would remain a question of fact whether profits from the disposition are taxed as business income or a capital gain.

“A question of fact.” Not a capital gain. Not automatically anything.

Past 365 days you return to the ordinary law that existed before 2023 — where the CRA looks at what you were actually doing and decides accordingly. The deeming rule set a floor. It did not build a ceiling.

What “question of fact” means in practice

When the CRA weighs whether a property sale is business income or a capital gain, the recurring themes are your intention at the time of purchase, what you did with the property, and your pattern of behaviour.

Consider what a renovate-and-resell looks like against that:

• You bought it specifically to renovate and resell
• You never lived in it and never rented it out
• You renovated immediately and listed on completion
• You have done it before, or intend to do it again
• You financed it short-term because you always planned a quick exit

Holding that property for 380 days does not change a single line of that. You did a flip. You did it slightly slower.

The people who genuinely have a capital gain are usually the ones whose facts changed — they bought to hold and rent, circumstances shifted, they sold. The holding period supports that story. It does not create one.

Why the mistake is expensive

Business income is included in taxable income at 100%. A capital gain is included at 50%. On $120,000 of profit at a 40% marginal rate, purely for illustration, that is roughly $48,000 versus $24,000.

Someone who prices a deal assuming the capital gains treatment they think day 366 buys them can be out by tens of thousands on a single flip — and they find out at filing, long after the money is spent.

Two more things the 366-day theory ignores

Losses are deemed nil inside the window. If the deeming rule applies and the deal loses money, the CRA treats the loss as nil. You cannot claim it. The rule is asymmetric: it takes the upside as business income and refuses the downside.

In BC there is a second clock at 730 days. The BC home flipping tax runs to two years and is entirely separate from the federal rules. Day 366 is not past that one either — it is barely half way. See the 730-day rule for the sliding scale.

The life-event exceptions

The deeming rule steps aside where the sale can reasonably be considered to occur because of, or in anticipation of, specific life events — death, a related person joining or leaving your household, marriage or common-law breakdown with at least 90 days living separate and apart, a threat to personal safety, or serious illness or disability, among others.

These exist for lives that go sideways. They are not a holding strategy, and treating them as one is how people end up explaining themselves to an auditor.

What to do instead

• Model every flip as business income unless your accountant has looked at the specific facts and told you otherwise, in writing.
• Do not let a holding period drive the exit on the belief that it changes the tax character. Federally it usually does not.
• Keep the record you would want to show — what you intended, what changed, and when. Intention is evidence, and evidence is contemporaneous or it is nothing.
• Price the deal on the tax you will actually pay. A flip that only works at capital-gains rates is not a flip that works.
