▶ How is this calculated? (formulas)
1. Capital gain
Capital gain = Proceeds of disposition − Adjusted Cost Base (ACB)
ACB = original purchase price
+ transaction costs (commissions, legal fees)
+ capital improvements (renovations, additions)
+ reinvested dividends / return-of-capital adjustments
(for real estate: land transfer tax at purchase counts too) 2. Inclusion rate — confirmed 50% (not 66.67%)
Taxable gain = Capital gain × 50% The proposed increase to 66.67% (2/3) was FORMALLY CANCELLED on March 21, 2025 by the Department of Finance Canada. Source: canada.ca/en/department-finance — "Government Announces Cancellation of Capital Gains Tax Changes" Only 50% of the gain is added to your income. The other 50% is yours, tax-free.
3. Principal Residence Exemption (PRE)
Full PRE: Taxable gain = $0 (home was your principal residence every year) Partial PRE formula (ITA s.40(2)(b)): Exempt fraction = (1 + years designated as PR) / total years owned Exempt gain = Capital gain × exempt fraction [capped at 100%] Taxable gain = (Capital gain − Exempt gain) × 50% inclusion The "+1" bonus year accounts for the purchase/sale overlap year. Example: owned 10 years, designated PR for 7 years: Exempt fraction = (1 + 7) / 10 = 0.80 80% of the gain is sheltered; 20% × 50% = 10% is taxable.
4. Tax calculation — marginal delta method
Tax on gain = Tax(otherIncome + taxableGain) − Tax(otherIncome) This correctly handles bracket straddles: if the gain pushes you from 20.5% into 26%, only the portion above the bracket threshold is taxed at the higher rate. Federal 2025 brackets (blended first bracket per Bill C-4): $0 – $57,375 14.5% $57,375 – $114,750 20.5% $114,750 – $177,882 26% $177,882 – $253,414 29% Over $253,414 33% Provincial rates layered on top (varies by province).
About the Canadian Capital Gains Tax Calculator
The 50% inclusion rate — confirmed, not in dispute
As of this writing (2025), the capital gains inclusion rate in Canada is 50% for all individuals. Only half of your capital gain is included in taxable income; the other half is entirely tax-free. A proposal in the 2024 federal budget would have raised this to 66.67% (two-thirds) for individuals on gains over $250,000 per year. That proposal was formally withdrawn on March 21, 2025 by the Department of Finance Canada — it never became law. Many websites, articles, and calculators still quote 66.67%. This calculator uses the correct, confirmed rate.
What is Adjusted Cost Base (ACB)?
Your ACB is not simply what you paid for the asset. For stocks, it includes every purchase at a weighted-average cost, plus any reinvested dividends (DRIP shares add to ACB), minus any return-of-capital distributions (which reduce ACB below zero in some cases, with a capital gain triggered). For real estate, ACB includes the purchase price, land transfer tax, legal fees, real estate commissions paid at purchase, and the cost of capital improvements — things like a new roof or addition. Day-to-day maintenance does not count. Getting your ACB wrong is the most common capital gains calculation error.
Principal Residence Exemption (PRE)
Your principal residence (the home where you ordinarily live) is exempt from capital gains tax in Canada under ITA s.40(2)(b). You can only designate one property per family unit as principal residence per year. If you owned the property for all the years and designated it as your PR for all those years, the full gain is sheltered.
The partial PRE formula — one of the most underserved calculations on the web — applies
when you rented part of the property, used it as a vacation home (not primary residence every year), or
changed its use at some point. The formula from ITA s.40(2)(b) is:
exempt fraction = (1 + years designated) / total years owned.
The "+1" is a bonus year the CRA allows to cover the year of purchase or sale, preventing you from being
taxed for a year of mere transition.
The flipping rule (held under 365 days)
Since 2023, if you sell a housing property within 365 days of acquiring it (and none of the life-event exceptions apply), the gain is deemed to be business income — not a capital gain. This means 100% of the gain is taxable (not 50%), and the principal residence exemption does not apply. The anti-flipping rule (Residential Property Flipping Rule, effective Jan 1 2023) was introduced to slow speculative short-term real estate purchases. This calculator does not apply the flipping rule automatically — if this scenario applies to you, consult a tax professional.
Why your marginal rate matters more than your effective rate
Capital gains are taxed at your marginal rate — the rate on the next dollar of income — not your average effective rate. If you already earn $100,000 and realize a $200,000 capital gain, the first $14,750 of the taxable gain (50% × gain) will be taxed at ~29.65% (ON combined) and the rest at higher rates. This calculator uses the marginal-delta method: it computes the tax at (other income + taxable gain) minus the tax at (other income), correctly capturing any bracket crossovers.

Frequently asked questions
What does the 50% capital gains inclusion rate mean?
Only half of your capital gain is added to your taxable income — the other half is entirely tax-free. A proposal in the 2024 federal budget would have raised this to 66.67% for individuals on gains over $250,000 per year, but that proposal was formally withdrawn on March 21, 2025 by the Department of Finance Canada and never became law. This calculator uses the correct, confirmed 50% rate.
How do I calculate my Adjusted Cost Base (ACB)?
Your ACB is not simply what you paid for the asset. For stocks, it includes every purchase at a weighted-average cost, plus any reinvested dividends (DRIP shares add to ACB), minus any return-of-capital distributions. For real estate, ACB includes the purchase price, land transfer tax, legal fees, real estate commissions paid at purchase, and the cost of capital improvements like a new roof or addition — day-to-day maintenance does not count. Getting your ACB wrong is the most common capital gains calculation error.
When does the Principal Residence Exemption apply — and when doesn’t it?
Your principal residence (the home where you ordinarily live) is exempt from capital gains tax under ITA s.40(2)(b), as long as you owned it and designated it as your principal residence for every year of ownership. It does not fully apply to a second property, such as a rental or a cottage you did not designate every year — in that case a partial exemption applies: exempt fraction = (1 + years designated as PR) / total years owned, with a "+1" bonus year covering the purchase or sale year. Only one property per family unit can be designated as principal residence in a given year.
How is the taxable portion of my gain taxed at the provincial level?
The taxable gain (50% of your capital gain, after any PRE exemption) is added on top of your other income for the year, then taxed at your marginal rate — the rate on your next dollar of income, not your average rate. This calculator uses the marginal-delta method: it computes tax at (other income + taxable gain) minus tax at (other income alone), so it correctly captures cases where the gain pushes you across a federal or provincial tax bracket.
Does the 50% inclusion rate always apply, even if I sell within a year of buying?
No. Since 2023, if you sell a housing property within 365 days of acquiring it and none of the life-event exceptions apply, the anti-flipping rule deems the gain to be business income rather than a capital gain — meaning 100% of the gain is taxable (not 50%), and the principal residence exemption does not apply. This calculator does not apply the flipping rule automatically; consult a tax professional if this scenario applies to you.
