How Much Is Capital Gains Tax on Real Estate in Canada?

Principal residence exemption (PRE) in detail

The PRE allows you to avoid capital gains tax on the sale of a property you have designated as your principal residence for every year you owned it. The formula effectively gives you a one-plus-year rule for the year you move out, which adds flexibility when selling and buying don’t line up perfectly. Only one property per family unit (you, your spouse, and unmarried minor children) can be designated as principal residence per year — critical for families with both a primary home and a cottage.

Even when fully exempt, the sale of a principal residence must be reported on your tax return on Schedule 3 and Form T2091 (“Designation of a Property as a Principal Residence by an Individual”). Failing to report can result in late-filing penalties of $100/month up to a maximum of $8,000. CRA introduced this reporting requirement specifically to enable enforcement against the anti-flipping rules and against improper PRE claims.

What’s taxable when you sell

• Rental and investment properties — fully taxable as capital gains in most cases. Capital cost allowance recapture may also apply if you’d been depreciating the building.
• Second homes (cottages, vacation homes) — taxable for years not designated as principal residence. The math of designating which years to which property gets technical when you have a primary home and a cottage.
• Pre-construction assignments — some treated as business income (fully taxable, no 50% inclusion rate) rather than capital gains depending on intent and pattern.
• Properties “flipped” within a short window — taxed as business income under the federal anti-flipping rules introduced in recent years. Held less than 12 months and you’re presumptively flipping unless a specified life-event exception applies (death, divorce, illness, work relocation, etc.).
• Inherited property — tax payable on the deemed disposition by the deceased’s estate, not the heir. The heir’s adjusted cost base steps up to fair market value at date of death.
• Non-resident sellers — 25–50% withholding may apply at closing pending CRA Section 116 clearance certificate.

How the tax is calculated

Capital gain = proceeds of sale − adjusted cost base (ACB: purchase price + capital improvements + transaction costs) − selling costs (commission, legal fees). A portion of that gain is then included in income at the prevailing inclusion rate. The 2024 federal proposal to raise the inclusion rate from 50% to two-thirds (66.67%) on gains above a $250,000 annual threshold was deferred and then officially cancelled by Finance Canada in 2025, so the long-standing 50% inclusion rate continues to apply to all capital gains in the 2026 tax year. The included half is then taxed at your marginal rate.

Always verify the current inclusion rate, threshold, and any exemptions (lifetime capital gains exemption for qualified small business shares or qualified farm/fishing property, which generally do not apply to residential real estate but may apply to certain commercial holdings) with your accountant before closing. The cost of getting this wrong on a $400K capital gain is materially larger than the cost of the tax-planning conversation.

Special situations to flag with your accountant

• Renting out part of your principal residence — partial PRE may apply, with the rented portion potentially attracting capital gains tax on disposition.
• Converting a rental to your principal residence (or vice versa) — deemed disposition rules under section 45(1) of the Income Tax Act may apply, triggering tax even though no sale occurred.
• Inherited property — fair market value at the date of death is the deemed acquisition cost. If the deceased’s estate already paid the deemed-disposition tax, your ACB for future sale is the FMV at death.
• Non-resident sellers — a 25–50% withholding may apply at closing pending CRA clearance certificate. Plan ahead: clearance certificates can take 4–12 weeks.
• Joint ownership — each owner reports their share of the gain. Spousal attribution rules can apply if funds were transferred between spouses to acquire the property.
• Pre-2017 cottage purchases — special grandfathering rules may apply because Canada didn’t require principal-residence reporting before 2016.

Reducing or deferring the tax bill

The most common legitimate tax-reduction strategies for real estate investors: maximise eligible capital improvements added to ACB (renovations, additions, structural improvements — not regular maintenance); ensure all transaction costs and commission are included in the capital-gain calculation; consider RRSP top-ups in the year of sale to offset taxable income; use spousal income-splitting where applicable; time the sale across tax years where the gain is large.

What doesn’t work: claiming PRE on a property you didn’t actually live in; calling a flip a “long-term hold” when the pattern shows otherwise; failing to report. CRA has invested heavily in real-estate tax compliance over the past decade, and provincial property data, MLS® records, and municipal sale records are routinely cross-referenced. See our closing-cost guide for the seller-side cost breakdown that affects your capital-gains math.

Frequently Asked Questions

Do I need to report the sale of my principal residence?

Yes. Even when the gain is fully exempt under the PRE, the sale must be reported on Schedule 3 and Form T2091. Failing to report can result in late-filing penalties of $100/month up to $8,000.

Are pre-construction assignments capital gains or business income?

It depends on intent and pattern. CRA can treat repeated assignments as business income — fully taxable, not 50% — and may apply HST. Get specific advice before assigning, particularly if you’ve done one before.

Are there exemptions for cottages?

A cottage can be designated as principal residence for some years, but only one property per family per year. The math of which years to designate to which property gets technical — it’s the kind of question worth paying for.

What’s the federal anti-flipping rule?

Properties held less than 12 months are presumptively taxed as business income (fully taxable, no PRE) unless a specified life-event exception applies: death, divorce, serious illness, work relocation of 40km+, addition to the household, threats to safety, or insolvency. The exceptions are narrow.
