Principal Residence Exemption: Get the Designation Right
Since 2016 the exemption must be claimed, and the choice can't be undone. Work through the rules, the multi-property decision, change of use, and the traps that turn an exempt gain into a tax bill.
The Principal Residence Exemption Looks Simple. The Costly Mistakes Happen on the Files That Aren't.
Since 2016, the exemption must be actively designated on the return or it is lost, and the choice generally cannot be revisited later. Most sales are straightforward. The exposure sits in the files that aren't: a client who owns both a home and a cottage, changed a property's use, holds land over half a hectare, sold a foreign property, or holds title jointly with a child. This session works through the rules and the planning decisions that determine how much of a gain stays exempt.
The most expensive error is designating the wrong property. What governs the choice is gain per year, not the largest gain or the first property sold. In the worked example, claiming the house over the faster-appreciating cottage exposes an extra $410,257 of gain, roughly $109,000 in tax, on a decision that could not be reversed once filed.
- check_circle The rules, then the planning. The section 54 definition and the 40(2)(b) gain reduced to a usable formula, followed by the decisions that actually move the number, with worked examples throughout.
- check_circle The multi-property decision. Why gain-per-year, not absolute gain, governs which property to designate, and how the "one plus" rule and overlapping ownership feed the calculation.
- check_circle Land and change of use. The half-hectare limit and when excess land qualifies, minimum-lot-size proration, and the 45(2) and 45(3) elections, including when electing or revoking changes the result.
- check_circle The traps in ordinary files. The 12-month flipped-property rule, foreign property and the foreign tax credit, trust ownership, U.S. citizens in Canada, joint title and probate, and thirteen common errors.
What You'll Learn
From the core rules and the exemption formula, through the multi-property decision, the land restrictions, change of use, and foreign and trust ownership, to the common errors that cost clients the exemption.
expand_more The Rules, the Formula, and Why a Sale Gets Missed
- Why designation now matters: the exemption must be claimed even on a fully exempt gain, and how to late-file under the fairness provisions when it is missed
- The section 54 definition and 40(2)(b) gain reduced to the exempt-portion formula, and exactly when the "one plus" is available
- What qualifies: home, cottage, ski chalet, farm, foreign condo, mobile home, trailer, houseboat, and co-op share
- The "principal" misconception, the ordinarily-inhabited test, who counts as an occupant, and how to prove occupation if CRA asks
- The T1-season habit that catches missed sales: watch for a change of address and ask about a second residence
expand_more Two or More Properties: The $109,000 Decision
- The governing principle: designate the property with the highest gain per year, not the largest gain or the one sold first
- Ben and Bernice worked in full: a house and cottage where the optimal split leaves $256,410 taxable instead of $666,667
- The $410,257 difference and its roughly $109,000 tax cost, permanent once the return is filed
- Why you must test the alternatives before committing to a designation
- Adam's example: why the "one plus" is denied when a property is acquired while non-resident
expand_more The Land Restriction and Excess Land
- The half-hectare limit and the objective "necessary for use and enjoyment" test: necessary, not merely desirable
- The two ways to justify excess land: property geography and subdivision restrictions such as minimum lot size, greenbelts, and septic or fish-habitat rules
- Minimum lot size as a year-by-year determination after Cassidy, with a worked five-acre example showing when "restarting the clock" produced a larger exempt gain
- Adjacent lots, houses straddling a boundary, integrated condo units, duplex land, and land partly used in a business
- The planning point: building across two minimum-size lots to bring both into the claim
expand_more Change of Use and the Flipped-Property Rule
- The 45(1) deemed disposition on a change to income use, and the 45(2) election to defer it and add up to four designation years
- The 45(3) election going the other way, from income use back to residence, and its conditions
- Candice's example: how revoking the 45(2) election in the right year cut the reportable gain to almost nothing
- Partial change of use, renting a room or basement, and the CCA line that turns incidental use into a disposition
- The flipped-property rule: sale within 12 months as business income, the 12(13) life-event exceptions, and the rollover situations that can trigger it unexpectedly
expand_more Foreign Property, Borrowing, and the Foreign Tax Credit
- Why claiming the exemption on a foreign property can waste it, removing the foreign non-business income the tax credit needs
- Elaine's New York condo, where claiming the exemption is a mistake, and Fred's Florida property, where a one-year claim tunes Canadian tax down to match the foreign credit
- Interest deductibility and the purpose test: the use of the funds, not the mortgage security, governs, per Henry and the Singleton case
- U.S. citizens and green-card holders in Canada: the US exemption cap and the risk of substantial U.S. tax on a gain fully exempt in Canada
expand_more Trusts, Estates, Probate, and Thirteen Common Errors
- Trust ownership: the post-2016 restrictions, the three trust types that still qualify, and the 40(4) and 40(7) interplay on rollovers
- Joint title with a child and probate: bare trust versus co-ownership versus right of survivorship, and how each affects the exemption
- A loss on a residence owned by an estate: how a vacant post-death property can generate a capital loss carried back under 164(6)
- Property rented to a child, cash back on a purchase, and the taxable forfeited deposit the exemption cannot shelter
- The thirteen common errors, from wrong designations and excess land to forgotten 1994 elections, non-resident years, and the missed change of address
