Capital Gains Tax on Selling a Home in Canada: How the Principal Residence Exemption Actually Works

Capital Gains Tax on Selling a Home in Canada: How the Principal Residence Exemption Actually Works

Short answer: If a home was your principal residence for every year you owned it, the capital gain on its sale is exempt from tax in Canada, provided you report the sale and designate the property on your return. If it was your principal residence for only some years, a formula shelters the gain year by year and the rest is a capital gain, half of which is included in income. If you owned the home for less than 365 consecutive days, a separate flipping rule deems the profit to be business income, fully taxed, with no exemption at all, unless a listed life event caused the sale. The exemption is claimed at filing time, not granted at the land registry office, and since 2016 an unreported sale can cost you the exemption itself.

This guide is education, not tax advice. Property files with a cottage, a rental conversion, a separation, or a period of non-residence can turn on facts that do not fit a general guide. A tax professional who works on real estate files can apply the rules to your dates and documents before you file.

The five gates a home has to pass

The Canada Revenue Agency sets four conditions for a property to qualify as a principal residence for a given year, and a fifth practical gate sits on top of them at filing time:

1. It is a housing unit. A house, cottage, condominium, apartment, duplex unit, trailer, mobile home, or houseboat can qualify, as can a leasehold interest in a housing unit or a co-operative housing share that gives you the right to live in a unit.
2. You own it. You can own the property alone or jointly with someone else.
3. Someone in the qualifying circle lived in it during the year. You, your current or former spouse or common-law partner, or any of your children must have lived in the home at some time in that year. A parent or sibling living there does not count unless a separate rule for minor children applies.
4. You designate it. The designation is made when you sell, on the forms covered below. One property per family unit per year can carry the designation, a limit that has applied since 1982.
5. You report the sale. For 2016 and later tax years, the CRA allows the exemption only when the disposition and the designation are reported on the return for the year of sale. Fully exempt sales still get reported. The paperwork gate is in the filing section near the end of this guide.

The land under the home counts as part of the principal residence, usually up to half a hectare, about 1.24 acres. Land beyond that is included only if you can show the extra land is needed to use and enjoy the home, for example where a municipal minimum lot size during your ownership years was larger than half a hectare. On a large rural lot, the gain may need to be split between the exempt half hectare and the taxable remainder at sale time.

Inhabitation deserves a closer look because sellers trip on it. The tax law uses the phrase "ordinarily inhabited," and CRA guidance accepts even a short period of living in the home during a year as enough for that year, provided the use is genuine residence rather than a mailbox. What the rule does not do is let you designate a property nobody in the qualifying circle lived in. A cottage only you use can qualify. A house your adult child rents from you at market rent, where you never live, cannot be designated for those years, because the child paying rent as a tenant is an income use, and designation requires living in the property as a home.

The one-property-per-year limit, in plain terms

For 1982 and later years, a family unit designates one home per year. The family unit is you, plus a spouse or common-law partner you had throughout the year, unless you were separated for the whole year under a court order or written agreement, plus your children who had no spouse or partner of their own in the year and were under 18 during it. An adult child's home is designated, if at all, in that child's own family unit, not yours.

The limit matters the moment a household owns two homes at once: a city house and a cottage, a condo kept after combining households, or a former home rented out while you live in a new one. Every overlapping year can be designated to only one of the properties. The years you give to one property are years the other property cannot use, and the formula in the next section converts that choice into dollars. The choice is made property by property at each sale, which means the designation history of the property you sold first constrains what is left for the property you sell later. Keep a written record of which years went where; the second sale may happen a decade after the first.

The formula: designated years plus one, over years owned

The exemption shelters a fraction of the gain. The fraction is:

Exempt portion = total gain x (1 + years designated as principal residence) / years owned

Years owned means the tax years ending after you acquired the property, counting the purchase year and the sale year. Years designated means the years the property is designated as your principal residence and you were resident in Canada. The fraction cannot exceed one, so a home designated for every year owned is fully exempt: the plus one pushes the numerator one past the denominator and the result is capped at the whole gain.

The plus one exists for the moving year. When you sell one home and buy another in the same calendar year, both homes were lived in during that year, but only one can be designated for it. The extra year in the formula lets the sold home still come out fully exempt in that overlap case, as long as you were resident in Canada in the year you bought the new home. Outside a same-year move, the plus one simply means a home designated for all but one year of ownership is also fully sheltered.

The gain itself is computed the standard way: proceeds of disposition, minus the adjusted cost base (the purchase price, plus capital costs of acquiring the property, plus capital improvements such as an addition or a new roof structure, not routine repairs), minus the outlays and expenses of selling, such as real estate commission and legal fees on the sale. On the non-exempt slice, half the gain is included in income and taxed at your marginal rate. The inclusion rate is 50 percent for individuals, corporations, and trusts; the proposed increase to two-thirds, first scheduled for June 2024 and then deferred to January 2026, was cancelled in March 2025 and never took effect.

The formula priced three ways

All figures in this section are a labelled hypothetical. The dates, prices, and the 40 percent marginal rate are illustrations chosen to make the arithmetic easy to check, not a market average and not your tax rate. Your marginal rate depends on your province and your other income in the sale year.

Setup: a home bought in 2014 for an adjusted cost base of $400,000, sold in 2026 for $820,000, with $20,000 of selling costs. The gain is $820,000 minus $400,000 minus $20,000, which is $400,000. The home was owned across 13 tax years (2014 through 2026).

Years designated	Formula	Exempt gain	Taxable gain	Included in income (50%)	Tax at an assumed 40% marginal rate
13 of 13	(13 + 1) / 13, capped at 1	$400,000	$0	$0	$0
10 of 13	11 / 13	$338,462	$61,538	$30,769	about $12,308
7 of 13	8 / 13	$246,154	$153,846	$76,923	about $30,769

Three readings matter more than any single row:

• The plus one is worth a full year of gain. Designating 10 years shelters 11 years of gain. With a $400,000 gain spread over 13 years, each sheltered year is worth about $30,769 of gain, about $15,385 of income inclusion, and about $6,154 of tax at the assumed 40 percent rate. Designation years are the asset; allocate them deliberately.
• Three undesignated years are not fatal. The 10-of-13 row still shelters about 84.6 percent of the gain. Sellers sometimes assume a cottage designation in the middle years poisons the house exemption entirely. It does not; it prices out at the formula.
• The tax applies to the included half only. The $61,538 taxable gain in the middle row adds $30,769 to income, not $61,538. The full amount still counts for income-tested items that key off net income, which is one reason a large non-exempt gain can affect benefits and credits in the sale year beyond the tax line itself. Plan the sale year with your accountant if the non-exempt slice is large.

If the property is sold at a loss, different rules bite. A home is personal-use property, and a loss on personal-use property cannot be claimed as a capital loss. The exemption shelters gains; it does not convert a price drop into a deduction.

Two homes, one designation: spending years where the gain is

Households with a home and a cottage face the same trade every overlapping year: the designation year can shelter gain on only one property. The practical comparison is gain per year, computed property by property.

Take another labelled hypothetical. Your house gained $520,000 over 13 years, roughly $40,000 per year. Your cottage gained $260,000 over the same 13 years, roughly $20,000 per year. Designating the house for all 13 years shelters the house fully and leaves the cottage exposed on its full gain when it sells. Splitting years between them shelters part of both and leaves part of both taxable. Because the exemption runs on each property's own fraction at its own sale, the default move is to designate the property with the higher gain per year for the overlapping years, and to revisit the choice before each sale, since gains change as markets move and as ownership periods lengthen.

Two cautions belong with that shortcut. First, gain per year is a planning shortcut, not the statute: the formula works on total gains and whole designated years, and the plus one changes the value of the last year given to each property, so a real file deserves a year-by-year calculation before filing. Second, designation requires the ordinarily-inhabited condition in each designated year. You cannot designate a cottage nobody in the family unit used as a home in that year just because the math prefers it.

The timing of sales also interacts with designation. If the cottage sells first, you choose its designated years then, and those years are gone for the house. If the house sells first, the same constraint runs the other way. Where one sale is planned years before the other, model both orders before the first closing, not after.

Renting part of the home, renting all of it, and moving out

Part of the home earns income

If part of your home earns rental or business income and part is your residence, the CRA practice is that the whole property keeps its principal residence character when three conditions all hold: the income use is secondary to the main use as a residence, you make no structural change to support the income use, and you claim no capital cost allowance on the property. A basement suite rented to a tenant, with no structural change and no allowance claimed, is the standard case this practice covers; the rental income is still reported each year.

Where those conditions do not all hold, the selling price and the adjusted cost base are split between the residence part and the income part on a reasonable basis, such as square metres or number of rooms. The residence part is tested for the exemption; the income part produces a capital gain reported on Schedule 3, with any capital cost allowance recapture handled on the rental statement. Our seller closing costs guide prices the commission and legal side of the sale itself; the tax split is a separate calculation on top of those numbers.

The whole home changes use

Changing the use of a property is treated as a sale even when no buyer exists. If you move out and rent the whole home, or convert a rental into your home, you are generally deemed to have sold the property at fair market value on the change date and reacquired it at the same value. The gain up to the change is reported in that year, with the exemption available for the years the home was your designated principal residence. The reacquisition value becomes the new cost base going forward.

Two elections soften that deemed-sale rule, and both are made by letter rather than on a numbered form:

• Home to rental (subsection 45(2)). Electing under subsection 45(2) in the return for the year of the change means the change of use is treated as not having happened: no deemed sale, no immediate gain. While the election stands, you report the rental income, you cannot claim capital cost allowance, and you can keep designating the property as your principal residence for up to four additional years without living there, provided you designate no other property for those years and you are resident in Canada. The four-year limit is extended without a fixed cap where you live away because your employer, or your spouse's employer, requires the relocation, the employer is not related to you, your old home is at least 40 kilometres farther from the new work location than your temporary residence is, and you return to the original home while still with that employer, or by the end of the year after the employment ends, or the absence ends with your death during the term. To elect, attach a signed letter to the return for the change year describing the property and stating that you want subsection 45(2) of the Income Tax Act to apply.
• Rental to home (subsection 45(3)). Moving into a former rental triggers the same deemed sale by default. A subsection 45(3) election postpones reporting that disposition until the actual sale, and lets you designate the property as your principal residence for up to four years before you actually occupy it. The election is unavailable if you, your spouse, or a related trust claimed capital cost allowance on the property for any tax year after 1984 and on or before the change date; allowance claimed before 1985 can still produce recapture in the change year. The election letter goes with your return, and it must be filed by the earliest of 90 days after the CRA asks for it or your filing due date for the year you actually sell the property.

Partial changes joined the election system later: for changes on or after March 19, 2019, an election under 45(2) or 45(3) can also be made for a partial change of use, so converting part of a home to a rental does not force a deemed disposition of that part where the election is filed. Where no election is made on a partial change, the CRA usually treats the use as changed only where the income use is more than minor, structural changes were made, or allowance was claimed, which mirrors the three conditions above.

Elections are where the largest quiet losses happen. The 45(2) election has to be filed with the change-year return; it is not reconstructed casually years later at sale time. If you moved out and rented your former home in the last few years without filing, raise it with a tax professional promptly, because late-election relief is discretionary and the four designation years cannot be created retroactively by preference alone.

What the 45(2) election is worth, priced

One more labelled hypothetical, with fair market values assumed for illustration. You buy a condo for $500,000 in 2018 and live in it through 2022. In 2023 you move out and rent it. You sell in 2026 for $780,000. Assume the condo was worth $650,000 on the 2023 move-out date. The property was owned across nine tax years (2018 through 2026), and you designate no other property in 2023 through 2026.

Path	What gets taxed, and when	Exempt gain	Taxable gain at sale
No 45(2) election	Deemed sale in 2023 at $650,000: the $150,000 gain to that date is sheltered by designating 2018 to 2022 (plus one over six ownership years to 2023, full shelter). New cost base $650,000. Sale in 2026 produces a further $130,000 gain with no designation years left on this property.	$150,000	$130,000 (half included in income)
45(2) election filed in 2023	No deemed sale. You designate 2018 through 2026 (nine years) plus one over nine ownership years: the whole $280,000 gain is sheltered, subject to the four-year extension covering 2023 to 2026 exactly.	$280,000	$0

The election is worth the tax on $65,000 of included income in this illustration, about $26,000 at an assumed 40 percent marginal rate. The trade accepted for that shelter is real: no capital cost allowance during the rental years, rental income reported annually, and your designation years tied up so no other property can use 2023 to 2026. On a property you expect to sell as a rental with large annual allowance claims available, the comparison can run the other way, which is why the election is a calculation, not a reflex.

The flipping rule: under 365 days, the gain is business income

Since January 1, 2023, a housing unit in Canada, including a rental property, and a right to acquire one, such as a pre-construction purchase agreement being assigned, that you owned or held for less than 365 consecutive days before selling is a flipped property. The profit is deemed to be business income, not a capital gain. Three consequences follow: the full profit is taxed at your marginal rate with no 50 percent inclusion, the principal residence exemption cannot be claimed on it even if you lived there, and a loss on a flipped property is deemed to be nil, so a short-held sale at a loss produces no deduction either.

Nine life events take a short-held sale out of the flipped-property definition when the sale happened because of, or in anticipation of, the event:

Life event	The condition in brief
Death	The death of you or a related person
Household change	A related person joins your household, or you join theirs (a partner moving in, a birth, an adoption, care for an elderly parent)
Relationship breakdown	You had been living separate and apart from your spouse or partner for at least 90 days before the sale
Safety threat	A threat to the personal safety of you or a related person, for example domestic violence
Serious illness or disability	A serious disability or illness of you or a related person
Eligible relocation	Your new home is at least 40 kilometres closer to the new work location or school
Job loss	The involuntary termination of your employment, or your spouse's or partner's
Insolvency	Your insolvency
Destruction or expropriation	The property is destroyed, for example in a disaster, or expropriated

Passing 365 days is a floor, not a clearance. A sale after a year can still be taxed as business income on its facts: what you intended at purchase, how the purchase was financed, your occupation and history of similar transactions, and how the property was used all feed the older business-income analysis. If the gain is not flipped property and is a capital gain, it is reported on Schedule 3; if it is business income, it is reported as business activity. The exemption discussion in this guide applies to capital gains only. A gain taxed as business income was never eligible for the exemption in the first place, at any holding period.

Sellers of assigned pre-construction contracts should treat the holding clock with care. The right to acquire the unit is itself the property for this rule, so assigning the contract before closing can be a flipped property disposition even though you never took title. Assignment profits can also carry GST/HST consequences outside the income tax analysis. Our first-time buyer GST rebate guide covers the rebate side for buyers; assignors need their own advice on both taxes before signing an assignment.

Selling costs, buying costs, and where they land

Tax follows the gain calculation, not the cash in your bank account. Proceeds are the sale price; selling costs reduce the gain as outlays rather than sheltering proceeds dollar for dollar in cash terms. Commission, legal fees on the sale, and penalties or discharge costs that are truly sale expenses each have their own treatment, and mortgage prepayment penalties in particular are not automatically a selling outlay on a principal residence file. Our mortgage prepayment penalty guide prices how a mid-term break penalty is computed by lenders; whether any part of it affects your tax file is a question for your preparer with the discharge statement in hand.

On the cost side, the adjusted cost base starts with the purchase price and adds capital acquisition costs and capital improvements. Routine repairs and annual ownership costs, such as property tax and insurance, are not added to the cost base. Our property tax guide and land transfer tax guide cover the recurring and purchase-side charges respectively; neither turns a non-capital charge into a cost-base addition. Keeping invoices for capital work, such as an addition, a structural renovation, or a conversion, is what supports the cost base years later, and losing them costs real money at sale because an unsupported improvement is usually an unclaimed one.

Investment and rental properties sit outside the exemption entirely. Their gains are capital gains at the 50 percent inclusion when the sale is on capital account, reported with their own cost base and allowance recapture rules. The math framework for evaluating those properties before purchase is in our investment property math guide, and the designation competition in the two-homes section above is the reason a property can be a home for tax in one year and an investment in another only through the change-in-use rules, never by relabelling.

Filing the sale: the steps that protect the exemption

Reporting has been mandatory since the 2016 tax year, and the exemption is allowed only when the sale and designation are reported. The standard sequence for an individual seller is:

1. Report the disposition on Schedule 3 of the T1 return for the sale year, in the principal residence part of the schedule. A sale includes a deemed sale, such as a change in use without an election, and the final return of a deceased homeowner is handled by the legal representative with the representative's designation form instead.
2. Complete Form T2091(IND), Designation of a Property as a Principal Residence by an Individual (Other Than a Personal Trust). If the home was your principal residence for every year you owned it, or for every year except one, page 1 of the form is all the CRA asks for. For shorter designation spans, and where more than one property was sold in a year, the full form works through the year count and the exempt fraction, with a separate form for each property sold in the same calendar year.
3. Tick the matching designation box on Schedule 3 (box 1 at line 17900 for the all-years or all-but-one case). The schedule and the form have to tell the same story.
4. Keep the supporting file: purchase and sale agreements, closing statements, capital improvement invoices, any 45(2) or 45(3) election letter as filed, and your written record of designation years used on any earlier property sale.

If the designation is missed in the sale year, ask the CRA to amend that year's return. A late designation can be accepted in certain circumstances, and the penalty is the lesser of $8,000 or $100 for each complete month from the original filing due date to the date the request reaches the CRA in satisfactory form. The penalty is the smaller risk. The larger one is that an unreported sale leaves the year open to reassessment beyond the normal window and puts the exemption itself in question, a poor trade for skipping a one-page form on a fully exempt sale.

Quebec filers have a parallel provincial designation, and residents who spent part of the ownership period outside Canada face a reduced exemption because designated years count only for years of Canadian residence in the formula. Non-residents selling Canadian homes face withholding and clearance certificate steps on top of the gain calculation. Each of those files belongs with a preparer before closing, not after.

Traps that cost sellers the exemption, or part of it

• The unreported exempt sale. The gain is exempt and the seller files nothing. Since 2016 that file is incomplete by rule, and the fix later carries the late-designation penalty risk above plus an open reassessment window for the year.
• The second property nobody modelled. Years designated to the cottage at its sale cannot be redesignated to the house later. The first sale in a two-property household sets the second sale's ceiling.
• The rented former home with no election. Moving out and renting without a 45(2) letter creates a deemed sale in the move year and strands the later growth outside the exemption, as the priced comparison above shows.
• Capital cost allowance claimed on the home. Allowance is incompatible with the ancillary-use practice for part of a home and with both change-in-use elections. Claiming it to shave rental tax can cost multiples of the saving at sale.
• The quick resale assumed to be exempt. Under 365 days, living in the property does not rescue the exemption; the gain is business income unless a listed life event caused the sale, and a loss is deemed nil.
• The adult child's house on your title. A property is designated for years someone in your family unit lived in it as a home. A house bought for a parent to live in, or rented to an adult child, does not generate designation years for you, and its gain is a regular capital gain.
• Land beyond half a hectare assumed exempt. Acreage past the usual half-hectare limit needs evidence it is required for the use and enjoyment of the home. Without it, that slice of the gain is taxable.

Each trap is a filing-position problem, not a price problem: the sale price was fine, and the tax result was set by a form, an election, or a designation choice made earlier, often years earlier.

Frequently asked questions

Do I pay tax when I sell the home I live in?

If the home was your principal residence for every year you owned it, no tax is payable on the gain, but the sale still has to be reported on Schedule 3 with a Form T2091(IND) designation. For 2016 and later years the CRA allows the exemption only when the disposition and designation are reported. If the home was your principal residence for only part of the ownership period, the formula shelters the designated years plus one, and half of the remaining gain is included in income.

How is the principal residence exemption calculated?

The exempt portion is the total gain multiplied by (1 + years designated) divided by years owned, capped at the whole gain. The gain is the sale proceeds minus the adjusted cost base and the outlays of selling. Only designated years in which you were resident in Canada count in the numerator, and each year can be designated to one property per family unit. The remaining non-exempt gain is a capital gain with a 50 percent inclusion rate.

What does a capital gain on a home sale actually get taxed at?

Canada has no separate capital gains rate. Half of a non-exempt capital gain is added to your income for the year and taxed at your marginal federal and provincial rates, the same rates that apply to employment income. The proposed increase of the inclusion rate to two-thirds was cancelled in March 2025 before it ever applied, so the inclusion rate stays at one half. Your actual bill depends on the size of the gain, your province, and your other income in the sale year.

I own a house and a cottage. Which one should I designate?

Designate year by year, in total, the property with the higher gain per year of ownership, and redo the comparison before each sale because prices move. The plus one in the formula and the fact that each sale locks in its own designation years mean the choice deserves a year-by-year calculation on real numbers rather than a rule of thumb alone. A short designation history, kept in writing from the first sale onward, is what makes the second sale's calculation possible.

What happens if I rent out my home after moving?

Renting the whole home is a change in use and normally a deemed sale at fair market value in that year, with the exemption covering the gain for your designated years to that date and a new cost base starting at that value. A subsection 45(2) election filed with that year's return avoids the deemed sale, lets you designate up to four more years while renting (longer for qualifying employer relocations), and requires you to report the rental income and claim no capital cost allowance meanwhile. Without the election, growth after the move is outside the exemption.

I sold in under a year. Can I still claim the exemption?

Generally no. A home owned or held for less than 365 consecutive days is flipped property: the profit is deemed business income, fully taxed, the principal residence exemption is denied, and a loss is deemed nil. The only route out is a listed life event that caused the sale, such as a death, a relationship breakdown after at least 90 days living separate and apart, an eligible relocation of at least 40 kilometres closer to the new work, an involuntary job loss, insolvency, a serious illness or disability, a safety threat, a household addition, or destruction of the property. After 365 days the deeming rule stops applying, but a gain can still be business income on its facts.

Do I have to file anything if my gain is fully exempt?

Yes. Since the 2016 tax year, every sale of a principal residence is reported on Schedule 3, with Form T2091(IND) filed for the designation; page 1 only is required when the home was your principal residence for all years owned or all but one. If the designation is forgotten, ask the CRA to amend the sale-year return. A late designation can be accepted with a penalty of the lesser of $8,000 or $100 per complete month of lateness, and an unreported sale can leave the year open to reassessment.

Does claiming rental expenses or depreciation hurt the exemption?

Claiming capital cost allowance is the harmful step. For a home partly used to earn income, the CRA practice that keeps the whole property's principal residence character requires the income use to be secondary, no structural change, and no capital cost allowance claimed. Allowance also blocks both change-in-use elections. Ordinary rental income reporting does not hurt the exemption; in a 45(2) election period the rental income must be reported while the exemption is preserved.
