Principal Residence Exemption (2026): The Free Year Most People Waste
A home designated for every year you owned it is fully exempt, with no dollar cap. The formula adds one year on top, and if you also own a cottage that spare year shelters $25,000 of its gain at no cost to the home. You must still report the sale, every time, since 2016.
Canada exempts the gain on a home entirely rather than up to a limit, which is more generous than the American exclusion and more complicated. The complications are where the money is: the formula has a spare year in it, the reporting rule has teeth, and a quick sale is not a capital gain at all.
The formula, and its spare year
The exempt portion of the gain is:
Designate a home for all 20 years you owned it and the fraction is 21 over 20, more than the whole gain, so all of it is exempt. The extra year is not rounding. It is deliberate, so that the year you sell one home and buy another, when you technically own two, does not break the chain. If you only ever own one home at a time, it does nothing and you never notice it.
Own a second property and it becomes real money. Take a family who sell both a city home held 20 years with a $600,000 gain and a cottage held 20 years with a $500,000 gain. Only one property can be designated for any given year:
Computed on the 2026 federal and Ontario tables with a 50% inclusion rate, stacked on $120,000 of other income. Giving the cottage one designated year leaves the home fully exempt, because 1 plus 19 over 20 still exceeds one.
Moving one year from the home to the cottage shelters $25,000 more gain and saves $6,691 of tax, and the home remains entirely exempt either way. The arithmetic is simple once seen: the home needs only 19 designated years to reach 100%, so the 20th year is free to use elsewhere. Which property should take the remaining years is decided by gain per year of ownership, not by total gain.
Work out your own with the capital gains calculator, and see the inclusion rate for how the taxable half is worked out.
Reporting is not optional any more
Before 2016 a fully exempt sale needed no mention on a return. Since 2016 every disposition of a principal residence must be reported, on Schedule 3, with the property designated on Form T2091(IND). The exemption can be denied outright if you do not report it, and a late designation may carry a penalty of the lesser of $8,000 and $100 for each complete month it is late.
This is the most common and most avoidable mistake on this page. The sale is tax-free and the paperwork is still mandatory.
Sell inside a year and it is not a capital gain
For dispositions since 1 January 2023, a housing unit owned for fewer than 365 consecutive days is deemed to produce business income. Business income is fully taxable rather than half, and the principal residence exemption does not shelter it.
| A $500,000 profit in Ontario | Taxed on | Tax |
|---|---|---|
| Capital gain, held over a year | $250,000 | $124,414 |
| Business income, under 365 days | $500,000 | $258,238 |
Stacked on $120,000 of other Ontario income, 2026 rates. Excludes any GST/HST that can arise when a home is built or substantially renovated to sell.
The same profit costs $133,824 more when the clock says 364 days instead of 366. The rule has exceptions for genuine life events, including a death, a separation after at least 90 days apart, a serious illness or disability, an involuntary job loss, a work relocation, insolvency, and a threat to personal safety. Assignment sales of a right to buy are caught too.
The limits worth knowing
- One property per family, per year. Since 1982 spouses and common-law partners with their minor children are a single unit. Properties held from before 1982 can still carry a partial exemption from the years when each spouse could designate.
- 0.5 of a hectare of land, about 1.24 acres, including the ground under the house. More counts only if it was necessary to use and enjoy the home, which the CRA reads narrowly: a municipal minimum lot size above the limit is the usual way to establish it, and wanting a bigger garden is not.
- Ordinarily inhabited. You, your spouse or partner, or your child must have lived in it during the year. A seasonal cottage counts; a property bought purely to rent out does not.
- A change of use triggers a deemed sale at market value when a home becomes a rental. A subsection 45(2) election avoids the deemed sale and can keep the designation for up to 4 further years, as long as no capital cost allowance is claimed in them.
- Non-residents. Years in which you were not resident in Canada are not eligible years, and the extra year is unavailable if you were a non-resident in the year you bought.
What it means in practice
For a household with one home, the exemption is automatic in substance and the only real risk is forgetting to report the sale. For a household with a cottage or a second property, the designation is a decision worth money, and it is made at the point of sale with the benefit of knowing both gains. Keep the purchase documents, the closing statements and the receipts for improvements for every property you own: the years and the adjusted cost base are what the formula runs on, and a gain is computed from them decades later. Your marginal rate decides what it is all worth, which at $120,000 in Ontario is 43.41%; the income tax calculator has yours.
Frequently asked questions
Do I pay capital gains tax when I sell my home in Canada?
Usually not. A home you ordinarily inhabited and designate as your principal residence for every year you owned it is fully exempt. There is no dollar cap, unlike the United States, but only one property per family can be designated for any given year.
How is the principal residence exemption calculated?
The exempt share of the gain is one plus the number of years designated, divided by the number of years you owned it. Designate a home for every year and the formula exceeds one, so the whole gain is exempt. The extra year exists so that a year in which you sell one home and buy another does not cost you.
Can I claim the exemption on a cottage?
Yes, but only for years you do not designate another property. A family can designate one property per year. Because of the extra year in the formula, giving the cottage a single year costs the city home nothing when the home is designated for all the other years: in the example on this page it shelters $25,000 of cottage gain and saves $6,691 of tax.
Do I have to report the sale of my principal residence?
Yes, for 2016 and later years, even when the entire gain is exempt. You report the disposition on Schedule 3 and designate the property on Form T2091(IND). Miss it and the exemption can be denied; a late designation may carry a penalty of $100 a complete month to a maximum of $8,000.
What is the home flipping rule?
For dispositions since 1 January 2023, a housing unit owned less than 365 consecutive days is deemed to produce business income, not a capital gain. That means all of the profit is taxed rather than half, and the principal residence exemption does not apply. Life events such as death, a separation, a serious illness or an involuntary job loss are excepted.
How much land is covered?
Half a hectare, about 1.24 acres, including the land under the home. More qualifies only if you can show it was necessary to use and enjoy the home, for instance where a municipal minimum lot size was larger. Land beyond that is taxable on sale.
What happens if I rent my home out?
Changing the use normally triggers a deemed sale at fair market value. A subsection 45(2) election avoids that and can keep the home designated for up to 4 more years while you are not living in it, provided you do not claim capital cost allowance against the rental income.
Can a couple each claim a principal residence?
Not since 1982. Spouses and common-law partners, together with their minor children, count as one family unit and can designate only one property per year between them. Before 1982 each spouse could designate one, which is why some long-held second properties still carry a partial exemption.
