Capital gains and the principal residence exemption when selling during divorce

How the Principal Residence Exemption works in Canada

In Canada, gains on the sale of a principal residence are sheltered from capital gains tax via the Principal Residence Exemption (PRE), as set out in section 40(2)(b) of the Income Tax Act. To claim PRE for a given tax year, the taxpayer (or a member of their family unit) must have "ordinarily inhabited" the property as their principal residence in that year, and the property must be designated as the principal residence on Form T2091.

For most Calgary couples who lived in the same home throughout their marriage and sell on separation, the PRE produces a full exemption. No capital gains tax is paid by either spouse on the divorce sale.

The family unit concept

The Income Tax Act treats married couples and common-law partners as a single "family unit" for PRE purposes. A family unit can designate only ONE property as principal residence per year, no matter how many properties it owns. This matters most when:

The couple owned a Calgary home and a vacation property (Canmore cabin, lakefront condo) — only one qualifies for PRE in any year.
One spouse owned a separate condo as a rental property before marriage — only one can be designated PRE post-marriage.

Upon separation, each former spouse becomes a separate family unit and can each designate their own property as principal residence going forward. The transition year matters: only one of the two can claim PRE for the year of separation, unless a special rule applies.

Common Calgary divorce scenarios

Scenario A: Both spouses lived in the home for all years of ownership. The home is sold during divorce. PRE applies to every year of ownership. Full exemption. No capital gains tax.

Scenario B: One spouse moved out two years ago; home is sold now. Both spouses still claim PRE for those two years through the end of separation if both family units treat the home as their designated principal residence. Generally the result is still a full or near-full exemption.

Scenario C: The home has a basement suite or Airbnb income. The portion of the home used to generate income may not qualify for PRE. CRA generally accepts that a self-contained rental suite reduces the exemption proportionally. A tax accountant should calculate the prorated exemption.

Scenario D: The home was a rental property for part of ownership. If the couple rented it out for several years before moving in (or after moving out), capital gains accrue during the rental period. Section 45(2) and section 45(3) elections can preserve PRE during a change in use; an accountant should be engaged before the sale closes.

Frequently asked questions

Do I pay capital gains when I sell the matrimonial home during divorce?

Most Calgary divorcing couples pay no capital gains tax on the matrimonial home — the Principal Residence Exemption shelters the gain if both spouses lived there throughout ownership. Exceptions: rental suites, secondary residences, or extended periods when the home was rented out can trigger a partial capital gain.

What if my spouse moved out two years ago — does that affect the exemption?

Generally no. Each former spouse becomes a separate family unit upon separation, but the PRE typically still applies to those years through the date of sale. A tax accountant should confirm the designation strategy for the year of separation specifically.

What if the home has a suite or Airbnb income?

The portion of the home used to generate rental income may not qualify for PRE. CRA generally accepts a proportional reduction based on the square footage of the rental portion. Engage a tax accountant before the sale closes so the calculation matches what gets reported on each spouse's tax return.
