Selling your home can generate a significant capital gain — but the principal residence exemption (PRE) can shelter all or part of that gain from tax.
How the Exemption Works
The PRE eliminates capital gains tax on sale of a property designated as your principal residence for each year owned. Formula: (1 + years designated ÷ total years owned) × capital gain. If the property was your principal residence every year, the entire gain is sheltered.
Mandatory Reporting Since 2016
Since 2016, you must report the sale on your return (Schedule 3 and Form T2091/TP-274) even if fully exempt. Failure to report is a CRA red flag and carries late-filing penalties plus potential loss of the exemption.
Multiple Properties Complication
Only one property per family unit can be designated per year. If you own a cottage or investment property in addition to your home, you must strategically decide which property to designate each year to minimize total tax.
Common Issues
- Converted rental: Renting your home triggers a deemed disposition at fair market value
- Home office deduction: Claiming it may make part of the gain taxable
- Flipping rule: Properties held under 365 days (since 2023) are treated as business income
