Selling your home and wondering if the CRA takes a cut? For most Canadians selling the place they actually live in, the answer is a happy no thanks to the Principal Residence Exemption. But there are rules, a mandatory reporting step, and situations that can cost you the exemption. Here’s how it works in 2026.

Quick answer: The Principal Residence Exemption (PRE) lets you sell your main home tax-free on the capital gain no tax on the increase in value as long as it qualified as your principal residence for every year you owned it. Only one property per family per year can be designated. Even when the sale is fully exempt, you must report it on your tax return. The exemption can be reduced or lost if the home was a rental, used to earn income, or bought and flipped quickly.

Do You Pay Tax When You Sell Your Home? (Short Answer)

For a typical homeowner selling their main residence: no capital gains tax. The PRE shelters the entire gain. You only run into tax if the property wasn’t your principal residence for some years, was partly income-earning, or doesn’t otherwise qualify. Reporting is still required regardless.

What the Principal Residence Exemption Covers

The PRE exempts the capital gain on a property you designate as your principal residence. A qualifying property can be a house, condo, townhouse, cottage, or even certain mobile homes and houseboats and it generally includes the land under and around it, up to half a hectare (more if you can show extra land was needed to use and enjoy the home).

Eligibility Rules (Ordinarily Inhabited, One Per Family)

Three core rules:

Ordinarily inhabited: you (or your spouse/common-law partner, former spouse, or child) must have lived in it at some point during each year you claim.
One per family per year: since 1982, a family unit (you + spouse/common-law partner and minor children) can designate only one property as the principal residence for a given year. This matters if you own both a house and a cottage.
You must be a resident of Canada during the years you designate.

Because only one property per year can be exempt, families with two properties should plan which to designate for which years to minimize total tax.

Partial Exemption & the Formula

If a property was your principal residence for only some of the years you owned it (say you rented it out for a while), you get a partial exemption. The exempt portion is calculated with a formula:

Exempt gain = Total gain × [(Years designated as principal residence + 1) ÷ Years owned]

That handy “+1” rule means if a property qualifies as your principal residence in the year you sell (and you lived there), you often get an extra year of exemption helpful when you’ve owned two properties.

Example: You owned a home 10 years, designated it as your principal residence for 8 of them. Exempt portion = (8 + 1) ÷ 10 = 90% of the gain is tax-free; 10% is a taxable capital gain (of which 50% is included in income).

Reporting the Sale (Required Even If Fully Exempt)

Since 2016, you must report the sale of your principal residence on Schedule 3 and Form T2091 (for individuals) even when it’s fully exempt. Skipping this can mean losing the exemption or facing penalties. So: sold your home? Report it, even if you owe nothing.

Situations That Reduce or Void the Exemption (Rentals, Flips)

Watch out the PRE can shrink or disappear if:

You rented out the home (or a large part of it) those years may not qualify, creating a partial exemption. Big rental use can also trigger a “change in use.”
You ran a business from a substantial, dedicated part of the home.
You flipped it quickly under the federal property-flipping rule, a home sold within 365 days is generally taxed as business income (no PRE, no 50% rule), with life-event exceptions. BC’s separate home flipping tax may also apply within two years.
You owned it as a non-resident for some years.
You claimed CCA (depreciation) on it, which can affect the exemption.
