Principal Residence Exemption Calculator

Lived in it for years, then rented it out before selling? Only part of the gain is actually tax-free, and the formula surprises almost everyone the first time they see it.

How To Use This Calculator

Enter the total capital gain, how many years you owned the property, and how many of those years it was designated as your principal residence.

The formula adds one extra year of exemption to cover the year of change in use, then applies that fraction of years to the total gain. Own it for 12 years, live in it for 8, and roughly three-quarters of the gain comes out tax-free, not the eight-twelfths most people expect.

Years Designated As Principal Residence 8

Each family unit can only designate one property as a principal residence for a given year. If a change of use occurred, from principal residence to rental or vice versa, a Section 45(2) or 45(3) election may have deferred a deemed disposition at that time, not modeled here.

Total Gain: Exempt vs. Taxable

A T2091 designation must be filed with the return for the year of sale whenever the property wasn't a principal residence for every year owned, or whenever the gain isn't fully exempt. Missing this filing can trigger a penalty even when no tax is actually owing.
