Principal Residence Exemption: Complete Guide
Tax-Free Home Sale
The principal residence exemption (PRE) allows you to sell your home tax-free. But there can only be one PRE per family per year, so planning is crucial when you own multiple properties.
What Qualifies as a Principal Residence?
A housing unit (house, condo, cottage, etc.) that you:
- Owned (alone or jointly)
- Ordinarily inhabited at some point during the year
- Or that your spouse, former spouse, or child ordinarily inhabited
Types of Properties That Can Qualify
- House, condominium, apartment
- Cottage or vacation property
- Mobile home or trailer
- Houseboat
- Share in a co-operative housing corporation
The One-Per-Family Rule
Critical rule: Only ONE principal residence per family unit per year.
Family Unit Includes
- You
- Your spouse or common-law partner
- Your unmarried children under 18
This Means
- If spouse owns cottage and you own city home, only one can be PRE each year
- Must choose which property to designate for each year of ownership
- Planning required when selling either property
The PRE Formula
The exemption is calculated using the "plus one" formula:
Why "Plus One"?
- The extra year accounts for the fact you can't designate a property for the year of acquisition AND year of sale if buying a new home
- Provides a one-year cushion when moving
Example
You owned your home for 10 years and designate it as PRE for 8 years:
- Capital gain: $200,000
- Exempt: $200,000 × (1 + 8) / 10 = $180,000
- Taxable gain: $20,000
Reporting Requirements
Since 2016, you must report the sale and designation:
Form T2091
- File with your tax return for year of sale
- Required even if gain is fully exempt
- Failure to file: Exemption may be denied
Schedule 3
- Report the sale on Schedule 3 (Capital Gains)
- Claim the exemption
- Net gain should be zero if fully exempt
Important: Not reporting your home sale (even if tax-free) can result in a $8,000 penalty and denial of the exemption. Always file the required forms.
Multiple Property Strategy
When you own both a home and cottage:
Option 1: Designate Property with Larger Gain
- Calculate potential gain on each property
- Designate more years to property with larger gain per year
- Use plus-one year on property you sell first
Option 2: Staggered Sales
- Sell one property, use full exemption
- Wait, then sell other property
- Each gets full benefit of ownership years
Example Planning
Own city home (15 years) and cottage (15 years):
- City home gain: $600,000
- Cottage gain: $300,000
- Designate city home for 10 years ($400/year of gain/year)
- Designate cottage for 5 years ($200/year of gain/year)
- Maximize total exemption on larger gain
Change in Use Rules
Converting Principal Residence to Rental
- Deemed disposition at FMV when you change use
- Can elect to defer gain (no immediate tax)
- Election preserves PRE for up to 4 years after moving out
- Cannot claim CCA on the property to preserve election
Converting Rental to Principal Residence
- Deemed disposition at FMV
- Capital gain on rental years is taxable
- Future gain on PR portion is exempt
Land Size Limits
- Half hectare (1.24 acres) included automatically
- Excess land only included if necessary for use and enjoyment
- Rural properties may need to justify larger land portion
- Excess land may be taxable even if house is exempt
Special Situations
Flipping Properties
- Frequent sales may be deemed business income, not capital gains
- Business income is 100% taxable (no 50% inclusion)
- PRE doesn't apply to inventory
- Anti-flipping rule: Properties owned less than 12 months are business income
Inherited Properties
- Receive property at FMV at death (usually)
- Only your ownership period counts for your PRE
- Cannot use deceased's designation years
Separation and Divorce
- Transfer to ex-spouse is tax-free rollover
- Ex-spouse inherits your designation history
- Plan carefully who keeps the home
Common Mistakes
- Not filing T2091: Required since 2016, even for tax-free sales
- Both spouses claiming: Only one PRE per family per year
- Renting part of home: May affect exemption proportionally
- Not tracking ACB: Need accurate cost base for calculation
- Ignoring anti-flipping: Short-term sales may not qualify
Calculating Adjusted Cost Base
Your ACB includes:
- Purchase price
- Land transfer taxes
- Legal fees on purchase
- Capital improvements (not repairs)
- Not deductible: Ongoing maintenance, mortgage interest
Capital Improvements
Additions to ACB:
- Renovations that add value (new kitchen, addition)
- Replacement of major systems (roof, furnace)
- Landscaping that adds permanent value
Provincial Considerations
The PRE is a federal rule, but provincial taxes also apply to any taxable portion:
- Ontario, BC have additional property taxes (speculation, vacancy)
- Quebec has slightly different rules for some situations
- Always consider both federal and provincial implications
