Principal Residence Exemption: How to Report Home Sales to Avoid Tax

The sale of your home can be one of the largest financial transactions in your life. In Canada, the Principal Residence Exemption (PRE) allows you to avoid paying capital gains tax on the sale of a property that qualifies as your principal residence. However, understanding how to properly report the sale to the Canada Revenue Agency (CRA) is essential to ensure you benefit fully from this exemption and avoid unexpected tax liabilities.

1. What Is the Principal Residence Exemption (PRE)?

The PRE is a tax relief provision that exempts the capital gain realized on the sale of your principal residence from income tax. A principal residence is a housing unit that you, your spouse or common-law partner, or your child ordinarily inhabited during the year.

Key points:

• The exemption applies only to one property per family unit per year.
• You can claim the exemption for years you designate the property as your principal residence, even if you didn’t live there all year.
• The exemption covers the increase in value from the time you acquired the property until you sold it.

2. Qualifying as a Principal Residence

To qualify, the property must meet these criteria:

• It is a housing unit: house, condominium, cottage, apartment, mobile home, trailer, or houseboat.
• You own the property either alone or jointly.
• You, your spouse/common-law partner, or your child ordinarily inhabit it during the year.

Even if part of the property is rented out or used for business, the PRE may still apply to the portion used as a principal residence, but only that portion’s gain is exempt.

3. How to Calculate Capital Gains on a Principal Residence

Capital gain = Sale price − (Adjusted cost base + Selling expenses)

The PRE can exempt all or part of this gain depending on the number of years designated as principal residence.

Formula for the exemption:

Exempt portion = (Number of years designated + 1) ÷ Number of years owned × Capital gain

The +1 is a “plus one” rule to cover the year of sale.

4. Reporting the Sale to CRA

Effective for dispositions after 2016, you must report the sale of your principal residence on your tax return—even if the entire gain is exempt. The key requirements:

• Complete Schedule 3 – Capital Gains (or Losses) on your T1 personal income tax return.
• Fill out the Principal Residence Exemption Worksheet section on Schedule 3, detailing:
• Address of the property
• Year(s) it was your principal residence
• Proceeds of disposition (sale price)
• Adjusted cost base and selling costs
• If you fail to report the sale, you may face penalties of up to $100 per month, to a maximum of $8,000, plus interest.

5. Special Situations and Considerations

5.1 Change in Use

If you convert a property from rental or business use to your principal residence (or vice versa), a deemed disposition at fair market value occurs, potentially triggering capital gains. You may be able to defer or reduce tax with an election.

5.2 Multiple Properties

Only one property per family unit can be designated as a principal residence for each year. If you own more than one, you must choose which to designate and calculate exemptions accordingly.

5.3 Spousal or Common-Law Transfers

Transfers of property between spouses or common-law partners are generally tax-deferred, meaning no immediate capital gain is recognized.

5.4 Properties Partially Used for Business or Rental

If part of your home is used for business or rental purposes, the exemption only applies to the portion used as your principal residence. The non-exempt portion may generate capital gains tax.

6. Step-by-Step Guide to Reporting Your Home Sale

1. Gather your documents: purchase agreement, sale agreement, receipts for improvements, and selling costs.
2. Calculate the adjusted cost base (purchase price plus eligible expenses).
3. Determine your capital gain: sale price minus adjusted cost base and selling costs.
4. Determine the number of years the property was your principal residence.
5. Complete Schedule 3 and the PRE worksheet on your tax return.
6. File your return by April 30 (or June 15 if self-employed) following the year of sale.

7. Consequences of Not Reporting

Failing to report a sale that qualifies for the PRE can result in:

• Monetary penalties and interest
• Reassessment by CRA with denied exemption
• Potential audits and additional scrutiny

8. Tips for Maximizing the Exemption

• Maintain thorough records of purchase, improvements, and selling costs.
• Consult with a tax professional if you own multiple properties or have mixed-use situations.
• Be proactive in reporting—even if no tax is owing, reporting is mandatory.
