The Home Flipping Tax, and Who It Catches

The rate is a straight line, and you can compute it. The Residential Property (Short-Term Holding) Profit Tax Act taxes net taxable income at 20% where the property was held 365 days or less. From day 366 to day 729 the Province's formula is 20% × [ 1 − ( (days held − 365) ÷ 365 ) ], the multiplier rounded to the nearest one-thousandth. At 730 days it does not apply at all. Taxable income is proceeds less the cost to acquire and to improve; net taxable income is that less the primary residence deduction, and cannot be negative. A house sold 550 days after purchase on $150,000 of profit carries a multiplier of 0.493, 9.86%, or $14,790. The same profit on day 200 costs $30,000.

The clock started before the tax did. The Act applies to dispositions on or after 1 January 2025, but it does not care when you bought. The Province states that property acquired before the effective date may be subject to the tax if it is sold on or after 1 January 2025 and was owned for less than 730 days, unless an exemption applies. There is no grandfathering. Every purchase from the first week of January 2023 forward has been inside the window at some point, and anything bought since late August 2024 is still inside it today.

What counts as property is wider than a house. Residential property means a housing unit in British Columbia with its adjacent land, or land with structures zoned all or in part for residential use and not part of another housing unit. It also means a right to acquire a beneficial interest in residential property, which is how presale contracts and their assignments are caught. A presale contract is taxable property in its own right, acquired on the day you pay for and enter into it, and disposed of when you assign it. Each person in the chain runs their own clock, so an assignee's 730 days begin on the assignment. Property used exclusively for a commercial purpose throughout is outside the tax, and needs no return.

The exemptions are life events, and each is tested. For individuals: death, or a disposition in anticipation of your own or a related individual's; serious illness or disability affecting you or a related individual; a marriage or common-law breakdown where you have lived separate and apart at least 90 days before the disposition; an eligible relocation for work or full-time study, where the new work or school is at least 40 kilometres closer for a primary residence, or a secondary property at least 100 kilometres farther from the new home; a change in household membership; involuntary termination of employment, expressly unavailable to the self-employed; and a threat to personal safety. For individuals, corporations and partnerships: insolvency, a housing unit destroyed by earthquake, fire, flood, landslide or spill, expropriation, foreclosure, inheritance, lottery winnings, and a developer pushing a completion date out by more than 365 days.

The primary residence deduction is not the principal residence exemption. They sound alike and behave nothing alike. The provincial deduction is $20,000 multiplied by your beneficial interest in the property, subtracted from taxable income, and it requires that you owned the property at least 365 consecutive days before disposing of it and occupied it as your primary residence, the place you resided longer than any other during the period. It caps the first slice of profit rather than sheltering all of it, and cannot take net taxable income below zero. On a 500-day hold with $60,000 of profit the rate is 12.6% and the base falls to $40,000, $5,040 payable. Under 365 days of ownership it is unavailable entirely.

Ninety days, and the exemption does not excuse the return. You must file within 90 days of disposing of a taxable property owned less than 730 days, through eTaxBC and directly with the Ministry of Finance, not with your income tax return and not through the CRA. A return is required even where net taxable income is $0, and even where you claim an exemption, unless that exemption sits on the short no-return list. The life-circumstance, builder and developer, and related-person exemptions all still require it. Late filing costs the greater of $500 or 5% of the balance owing, plus 1% of that amount per month to a maximum of twelve; a repeat becomes 10% and 2% to twenty. Interest runs at prime plus three points, compounded monthly.

The federal rule is a different instrument, and it stacks. Subsections 12(12) to 12(14) of the Income Tax Act apply to dispositions after 2022. A housing unit in Canada, or a right to acquire one, held less than 365 consecutive days is "flipped property": the taxpayer is deemed to carry on a business, the property is inventory, and the whole profit is business income, no capital gains treatment, no principal residence exemption, a loss denied outright. It creates no new tax; it recharacterises income and taxes it at your marginal rate. The provincial tax is a separate levy, running to 730 days rather than 365, which the Province states is not harmonized or administered with income tax. Both can apply to one sale, and their exception lists overlap without matching, CPABC has flagged that the federal rule has no related-party exception where the provincial one does. Nor does the provincial tax soften the federal bill: in technical interpretation 2025-1051441E5 of 12 June 2025, CRA concluded it is not deductible under paragraph 18(1)(a) and cannot be deducted in computing a capital gain.

Sourced from the Province of British Columbia's BC home flipping tax pages, the overview, the calculation page, the exemptions and life circumstance pages, the presale contract page, the glossary, and the filing and penalties pages, last updated between December 2024 and August 2026, with BCFSA Advisory 25-002 of 9 January 2025, the Department of Finance explanatory notes to subsections 12(13) and 12(14) of the Income Tax Act, CRA's Capital Gains guide T4037, CPABC's May 2025 commentary, and CRA technical interpretation 2025-1051441E5 of 12 June 2025; all verified 25 August 2026. This report describes and informs; it is not tax, legal or accounting advice, and a specific sale, a specific holding period and a specific exemption deserve specific verification by a professional.
