Does the principal residence exemption cover my whole BC acreage or cottage?
It shelters the gain on your home and up to half a hectare of land around it, one home per family a year, and land past half a hectare only where it's needed to use the home, such as a minimum lot size the zone sets.
Opens the report at this answer. A PID always finds the lot; an address needs an exact match.
What the answer means
When you sell a home you've lived in, Canada's principal residence exemption can take the capital gain out of income tax. On a city lot it usually covers all of it. On a rural lot over half a hectare (about 1.24 acres), or when a family owns a house and a cottage, it may cover only part, and how much turns on rules a buyer can plan for.
- What can be one
- A house, a cottage, a condominium unit, a mobile home or a houseboat, with the land under it and the land that contributes to its use and enjoyment as a home, that you, your spouse or common-law partner or your child ordinarily lived in during the year, even for a short time each year (Income Tax Act s. 54; Folio S1-F3-C2 ¶2.7, 2.10, 2.11). A cottage you use each summer can qualify; a property owned mainly to earn income, lived in only briefly, generally doesn't.
- One home per family a year
- For each year since 1982 a family (you, your spouse or common-law partner and your unmarried children under 18) can designate only one property (s. 54; Folio ¶2.13). A family that owns a house and a cottage chooses, when it sells one, which years to give it; the years given to one can't go to the other.
- The years that count
- The share of the gain sheltered is one plus the years designated, over the years owned (s. 40 (2) (b); Folio ¶2.20). The extra year lets you sell one home and buy another in the same year without losing a year. Years you owned the land before living there, building on vacant land for instance, count as years owned and not lived in.
- Half a hectare, and more only if needed
- Land past half a hectare is part of the principal residence only where you show it was needed for the home's use and enjoyment, not merely wanted (s. 54; Folio ¶2.33, 2.34). A zoning bylaw's or the Province's minimum lot size over half a hectare, or a rule that stopped the land being subdivided, normally makes the extra land part of it for the years the rule applied; land that could have been split off and sold doesn't count (Folio ¶2.35, 2.38). On a rural lot, the zone's smallest new lot (our report's zoning section, where the bylaw is summarised) is the usual evidence (our reading).
- Farmland
- On a farm with the home on it, the gain is split one of two ways: the home and a share of land valued at the greater of half a hectare of farmland or a typical residential lot nearby, or, by election with the return, the whole property's gain less $1,000 plus $1,000 for each year it was your principal residence (s. 40 (2) (c); Folio ¶2.39 to 2.44).
- Renting or a business
- Turning the whole home into a rental is a deemed sale at its value then, which an election can defer, and the home can still be designated for up to four years while rented (s. 45 (1), (2); Folio ¶2.48, 2.50). A suite or a home business that stays ancillary to living there, with no structural change and no capital cost allowance claimed, usually doesn't change its use (Folio ¶2.59).
- Reporting the sale
- Since 2016 a sale has to be reported on Schedule 3 of the return with the designation, on Form T2091(IND) when the whole gain isn't sheltered, even when no tax is owed (Folio ¶2.15). The CRA can accept a late designation, with a penalty of $100 a month up to $8,000 (s. 220 (3.21), (3.5)).
- Selling within a year
- A home held under 365 days in a row is taxed under the federal flipping rule as business income and isn't sheltered, unless a life event fits (s. 12 (12) to (14)), and BC's home flipping tax can apply on its own within two years.
- What it means for a buyer
- On an acreage, assume only the home and half a hectare are sheltered unless the zone or a covenant stops the land being split, and keep that evidence from the day you buy. With a house and a cottage, plan which one you'll designate with an accountant before you sell either (our reading).

Tax depends on the facts of each case and the Folio has more than these lines say; an accountant is the final word.

Before you buy: who to ask
- The seller or their agent
- Has the home been rented out, farmed or run as a business, and has the land ever been subdivided or offered for subdivision?
- The local government
- What is the smallest lot the zone allows, and could this lot be subdivided today? A minimum lot size over half a hectare is the usual evidence the extra land is needed.
- An accountant
- If I own another home, which should I designate for which years, and how would the land past half a hectare be treated if I sell?
