How it works

  1. We find your capital gain: proceeds of disposition minus your adjusted cost base minus selling expenses.
  2. Canada’s 50% inclusion rate applies, so only half of the gain is added to your taxable income.
  3. The taxable half is multiplied by your marginal tax rate to estimate the tax owing on the sale.

Frequently asked questions

What is the capital gains inclusion rate in Canada?

50%. Only half of a capital gain is included in your taxable income. A proposed increase to 66⅔% on gains above $250,000 was not enacted, so the 50% inclusion rate still applies for 2026.

Do I pay tax when I sell my principal residence?

Generally no — the principal residence exemption can eliminate the tax on a home you lived in. This calculator is for taxable property such as non-registered investments, cottages and rental properties.

What counts as the adjusted cost base (ACB)?

Roughly what you paid for the asset plus acquisition costs such as commissions and legal fees. Keep your records — the ACB is subtracted from your proceeds to find the gain.

Can capital losses reduce the tax?

Yes. Net capital losses can offset capital gains in the same year, be carried back up to three years, or carried forward indefinitely against future gains.

Which marginal tax rate should I enter?

Your combined federal-plus-provincial marginal rate on the next dollar of income. The province selector pre-fills the approximate top rate for 2026 — lower it if your income falls in a lower bracket.
