You don’t pay capital gains tax on the sale of your primary residence if the home qualifies as your principal residence in every year you owned it, or in all years but one. There is a catch that surprises people: since the 2016 tax year the CRA only allows the exemption if you report the sale on your return.
So a home sale with no tax to pay still needs paperwork. Here’s what to file and what happens when the exemption only covers part of the gain.
Does my home count as a principal residence?
The CRA gives four tests. It has to be a housing unit (a house, condo, cottage, trailer, or an interest in a co-operative housing corporation), you must own it alone or jointly, you or your spouse, common-law partner or child must have lived in it during the year, and you have to designate it. The CRA’s example of the land limit is half a hectare, about 1.24 acres, unless local rules require a larger lot.
Each family can name just one home per year. That matters if you own a house and a cottage, because both may have gained a lot and you can’t shelter both for the same year.
What does a plain sale look like?
Dana in Calgary bought a townhouse for $350,000 and sold it for $520,000 after eight years of living there. The gain is $170,000, and because the home was her principal residence for every year, none of it is taxable. The taxman never sends a bill. But Dana still reports the sale on her return and designates the home, because without that step the exemption isn’t allowed.
What do I actually have to report?
If you sold your home, or are deemed to have sold it, you report it on Schedule 3, Capital Gains or Losses, and you fill out Form T2091(IND) to designate it. The form asks for the address, the date you got the property and the sale proceeds. Do it even if the whole gain is exempt.
Forgot to designate in the year of the sale? Ask the CRA to revise the return you filed for that year. The CRA can accept a late designation in some cases, and a penalty may apply. We couldn’t confirm the penalty amount on the pages we read, so check the CRA’s page on late designations.
| Situation | What to do |
|---|---|
| Home qualified in every year | Report on Schedule 3 and Form T2091(IND), no tax on the gain |
| Home qualified in only some of the years you owned it | Part of the gain is exempt, the rest is a taxable capital gain |
| Rented out part of the home | Split by floor area or rooms, report the rented share on Schedule 3 |
| Home passed at death | Exemption runs to the date of death, heirs must qualify on their own |
How is a partly exempt gain worked out?
The CRA folio on principal residences gives the formula: the gain multiplied by B over C. B is one plus the number of years the home was your principal residence. C is the number of years you owned it. The extra year exists so that buying one home and selling another in the same year doesn’t leave you exposed.
Here’s a case. You bought a home for $400,000 and sold it for $700,000 after ten years, but you put a cottage forward as the designated home for two of those years. The gain is $300,000. The exempt share is (1 + 8) over 10, or 90%. That leaves 10%, or $30,000, as a gain, and half of that, $15,000, is taxable.
Suppose you also earn $60,000 from a job in Ontario. The capital gains estimator then shows about $4,600 of extra tax on the $30,000. In Manitoba the same gain costs about $4,990. You’ll need to feed in the reduced gain yourself, since the calculator doesn’t model the exemption. Selling costs such as legal fees and agent commission come off the gain, and the home sale proceeds calculator tallies those.
What if I rented part of it or ran a business from home?
Then only the share you used as a home is protected. The CRA says to split the property, using floor area or room count, and to report the gain on the rented part on Schedule 3. If you rented out the whole place, the full exemption story gets complicated fast, and it’s the one case where an accountant who does rental property earns the fee.

Common mistakes
The first is skipping the form because there’s nothing to pay. The second is assuming a cottage and a house are both covered. Only one home per family per year can be named.
Third, people forget the land. A big rural lot can go past the half hectare, and the extra land isn’t automatically covered. Fourth, some count the gain before selling costs, which overstates it.
Keep your paperwork, too. When you only need to prove a partly taxable gain, the purchase price, the closing statements and the receipts for big renovations (not routine repairs) are what back up your cost. Dig them out of the filing cabinet before the sale closes, not three years later when a CRA letter asks for them. A quick call to your lawyer’s office usually gets you copies of the closing documents.
Under the current rules you add only half of a gain to income. The federal government cancelled the plan to raise that to two-thirds. If you’re weighing whether to sell a second property, the marginal tax rate calculator gives the rate you’d pay on the next dollar of income.
How we checked the figures
The exemption rules, the reporting requirement and the half hectare limit come from the CRA‘s principal residence pages and Income Tax Folio S1-F3-C2. The inclusion rate comes from the CRA’s T4037 guide and a Department of Finance announcement on the cancelled increase. Examples use 2026 rates. This guide is independent of the CRA and any other government body.
Frequently asked questions
Do I pay capital gains tax when I sell my house?
Not when the home was your principal residence in every year you owned it, or every year except one. The sale still goes on your return.
Do I have to report the sale if there's no tax?
Yes. The CRA only allows the exemption for 2016 and later years if the sale and designation appear on your return, on Schedule 3 and Form T2091(IND).
Can I have two principal residences?
Not for the same year. A family can name one home per year.
How much land is covered?
Usually half a hectare, about 1.24 acres. More can qualify where local minimum lot sizes require it.
What if I forgot to designate the home?
Ask the CRA to revise the return for the year of sale. A late designation can be accepted in some cases, and a penalty may apply.
