Key takeaways
  • CRA allows the principal residence exemption only if the sale and the designation are reported on Schedule 3.
  • Typical review issues include whether the home was ordinarily inhabited, the flipping rule, and how the cost base was calculated.
  • If the exemption is denied, half of the resulting capital gain is taxable, and a home loss cannot be claimed.

A letter from CRA asking about a home sale can be stressful, especially when you thought the sale was tax-free. These letters are usually requests for information, and a calm, well-organized response helps.

This article explains what CRA tends to look at, what records are worth gathering, and what can follow if the claim is not accepted. Your letter will set its own response requirements, so read it closely.

This article covers Canadian federal tax law, which applies in every province.

What CRA looks at

Since the 2016 tax year, the sale of a principal residence must be reported on Schedule 3, even if there is no gain. CRA allows the exemption only if the disposition and designation are reported. A missing or inconsistent designation is a common reason for a follow-up.

Records worth gathering

Occupancy is a question of fact, and even a short period can be enough unless the main reason for owning was to earn income. So records showing who lived in the home, and when, matter.

Special situations CRA may ask about

If you owned the home, or a right to acquire it, for less than 365 consecutive days before you sold it, the gain is deemed business income. The property is treated as inventory rather than capital property, so the principal residence exemption does not apply. This applies to dispositions after 2022.

The flipping rule does not apply to a sale that can reasonably be considered to occur due to, or in anticipation of, certain events. These include the death of you or a related person, a related person joining your household, breakdown of a marriage or common-law partnership (where you have been separated at least 90 days), and a threat to your personal safety. They also include serious disability or illness, an eligible relocation, involuntary termination of employment, insolvency, and destruction or expropriation of the property.

If only part of the home is your principal residence and the rest earned income, the selling price and cost base are split by square metres or number of rooms, if the split is reasonable. Land of one-half hectare or less, including the area under the housing unit, is usually accepted as contributing to residential use. Land above that is generally not part of the principal residence unless it was necessary for use and enjoyment as a residence, for example because municipal minimum-lot or severance rules require it.

If the claim is denied

If the exemption is not allowed, the capital gain is proceeds minus the adjusted cost base and selling costs, and half of it is taxable. A home is personal-use property, so a loss on the sale cannot be claimed.

If the problem is that you forgot to designate, ask CRA to amend the return for the year of sale. CRA may accept a late designation, but a penalty may apply. That penalty is the lesser of $8,000 and $100 for each complete month between the due date and the date of the application. The Minister may waive or cancel penalties or interest if the request is made within ten calendar years after the tax year ends.

If you disagree with a reassessment, you generally have dispute rights, and deadlines apply. A lawyer can confirm which steps fit your situation.

What to do next

Frequently asked questions

Does a CRA letter mean I did something wrong?

Not necessarily. It may be a request for information about the sale or designation. Respond by the date given and support what you reported.

What if I forgot to report the sale?

The exemption is allowed only if the disposition and designation are reported. Ask CRA to amend the return; late designation may be accepted, but a penalty may apply.

Can I claim a loss if CRA denies the exemption?

No. A home is personal-use property, so a loss on sale cannot be claimed.

Does the exemption apply if I sold the home quickly?

Not if the flipping rule applies. A housing unit held less than 365 consecutive days is treated as inventory and the exemption does not apply. Exceptions exist for certain life events.
