Principal Residence Exemption — BC Seller Reference

The 50% inclusion rate, in 2 sentences

The federal capital-gains inclusion rate is 50% — meaning half of any taxable gain is added to your income for the year of sale. The proposed increase to 66.67% on gains above $250,000 was CANCELLED by the federal government on March 21, 2025, so the 50% rate is the operative rate across the board for the foreseeable future.

With a full PRE designation, the inclusion is offset to zero. Without the PRE, half the gain is added to your other income and taxed at your marginal rate — which for a $500,000 gain on a Vancouver detached home in the highest BC bracket is approximately $130,000 of tax. The cost of getting this wrong is large.

Frequently asked questions

• What is the Principal Residence Exemption (PRE)?

  A federal Income Tax Act provision that fully exempts the otherwise-taxable capital gain on a property that the seller (or a member of their family unit) "ordinarily inhabited" as a principal residence for every year designated. A Canadian-resident individual can designate one property per family unit per year. When fully designated for every year of ownership, the PRE eliminates 100% of the capital gains tax on the sale. The PRE is the single largest tax shelter most Canadians ever use — and it does not apply automatically.

• How is capital gain calculated on a BC home sale?

  Sale price minus adjusted cost base (purchase price + capital improvements + transaction costs) = gross capital gain. 50% of the gross gain is included in your income for the tax year of the sale (the federal inclusion rate). The 66.67% inclusion rate that was proposed for gains above $250,000 was CANCELLED on March 21, 2025, so the rate is 50% across the board for the foreseeable future. Without the PRE, that included gain is added to your other income and taxed at your marginal rate. With a full PRE designation for every year owned, the inclusion is offset to zero.

• Do I have to file anything if my entire gain is PRE-exempt?

  YES. Since the 2016 tax year, every disposition of a principal residence MUST be reported on Schedule 3 of your T1 personal tax return, with the PRE designation made via Form T2091(IND) — Designation of a Property as a Principal Residence. This is the single rule most BC sellers do not know exists. Failing to file is a CRA penalty trigger ($100 per month, max $8,000) and CAN COST YOU THE EXEMPTION RETROACTIVELY if CRA catches it on audit. The PRE is not automatic. You report and designate.

• I owned two properties — which one do I designate?

  You can only designate ONE property per family unit per year. If you owned a Vancouver condo and a Whistler cabin overlapping for several years, you have to choose which property gets the PRE for those overlap years. The optimization: pick the property with the higher per-year gain. There is also a "+1 rule" (one bonus year added to the designated period) that lets you cover the year of acquisition of a replacement property without losing a year of designation on either. A CPA can run the optimization across both properties; for high-gain dual-property cases, the difference between optimal and naive designation is often tens of thousands in tax.

• How does PRE interact with BC Home Flipping Tax?

  They are separate tests with separate exemptions. PRE (federal) exempts you from federal capital-gains tax on a property "ordinarily inhabited" as a principal residence — duration test is per-year designation. BC Home Flipping Tax (provincial) is a separate 20%-of-profit tax on dispositions within 730 days, with its own exemption list (life events: death, illness, work relocation, etc.). The federal PRE does NOT exempt you from BC FHFT. A BC seller who held their principal residence for 6 months, qualifies for full PRE federally, AND owes 20% BC Flipping Tax on the gross profit. They are different statutes with different tests; a CPA needs to model both before disposition.

• How does PRE interact with the federal anti-flipping rule?

  The federal anti-flipping rule (effective January 1, 2023) deems a sale of residential property held less than 365 days to be 100%-included business income — and explicitly REMOVES the PRE for those sales. If you sell within 365 days, you cannot claim the PRE on that sale (subject to specific life-event exemptions matching the BC FHFT list). After 365 days, capital gains treatment + PRE eligibility return. Practitioner truth: if you sold after 13 months, you may be eligible for full PRE federally. If you sold at 11 months, you owe full federal income tax on 100% of the gain — even if it was your only home.

• I rented out part of my principal residence — does PRE still apply?

  Partly. CRA permits "ancillary" rental use of a principal residence (e.g., a basement suite while you live upstairs) without losing PRE eligibility, provided three conditions: (1) the rental is ancillary to the main use as principal residence, (2) no structural change has been made to accommodate the rental, (3) no Capital Cost Allowance (CCA) has been claimed on the rented portion. If you rented out the full house for several years and lived elsewhere, those years are not eligible for PRE designation. If you claimed CCA on the rental portion, you have made a "change in use" election that creates a deemed disposition — verify with your CPA before relying on PRE for any year with rental income.

• I'm a non-resident selling a BC property — does PRE apply to me?

  Generally no. The PRE is available to a Canadian-resident individual for years they were ordinarily resident in Canada. A non-resident (under the Income Tax Act's residency tests) selling a BC property is not eligible to claim PRE for non-resident years. Additionally, non-residents disposing of "taxable Canadian property" face withholding under section 116 of the Act — typically 25% of the gross sale proceeds withheld until a Section 116 Certificate is obtained from CRA. The withholding is not the final tax; it's a deposit against the actual liability. Non-resident BC sellers should engage a CPA experienced in cross-border real estate tax months before listing.

• What if I forgot to file T2091 in a prior year?

  File the T1 Adjustment Request (T1-ADJ) to amend the prior year's return and designate the property. CRA will accept late designations in many cases — particularly if the omission was accidental and the PRE would have applied — but late-filing penalties can apply ($100 per month up to $8,000, per CRA's Income Tax Folio S1-F3-C2). The longer you leave it, the harder the conversation. If you are unsure whether you filed correctly when you sold a principal residence in 2021 or 2022, ask your CPA to check; a $100/month penalty for 36 months is $3,600 and easy to avoid by filing now.
