The math behind your result

Every number on this page is derived from the exact Canadian regulatory formula — not approximations or estimates. The calculation runs entirely in your browser using the inputs you provided.

▶ 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%

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 That proposal was formally withdrawn on March 21, 2025 by the Department of Finance Canada — it never became law.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.

Not financial advice. Tax rates change annually. This calculator uses 2025 CRA data. The principal residence exemption has many nuances (change-of-use elections, rental income history, home office, multi-family, trust ownership) not captured here. Consult a licensed tax professional before filing. All calculations happen in your browser — no input data is sent to any server.
