Does 50% inclusion mean a 50% tax bill?

No. One-half of an ordinary gain is included in taxable income under the general rule. The tool applies the hypothetical combined marginal rate you enter to that taxable amount.

Does this tool calculate the tax assessed by CRA?

No. It is a single-disposition illustration with important exclusions. Use the official instructions for your property and tax year.

Purpose Information & official-source navigation Page edited September 18, 2026 Reference Income Tax Act, section 38

What the official rule says: Under the general rule in section 38(a) of the Income Tax Act, one-half of an ordinary capital gain is included in taxable income. That is an inclusion rate, not a 50% tax bill.

What this tool does: It shows the gain on one disposition, its taxable portion before exceptions, and an illustration using a combined marginal tax rate you supply. It does not determine your actual tax rate or recommend a transaction.

Start with the source: Read section 38 of the Income Tax Act and CRA’s calculation and reporting instructions.

Read the result correctly

The first calculation is sale proceeds minus adjusted cost base and eligible selling expenses. For a positive, ordinary non-exempt gain, this tool then applies one-half inclusion. Finally, it multiplies that taxable amount by the combined marginal rate you entered. A large gain can cross tax brackets, so multiplying the whole taxable amount by one rate is only an illustration—not the additional tax calculated on a full return.

The old proposed $250,000/two-thirds inclusion structure is not used here. The general enacted rule above was checked on September 17, 2026. That check does not determine whether an exemption, special rule or different treatment applies to your property.

A worked arithmetic example

Suppose proceeds are $850,000, adjusted cost base is $400,000 and selling expenses are $35,000. The gain is $415,000 and the ordinary taxable portion is $207,500. If you enter a hypothetical combined rate of 30%, the illustrated tax amount is $62,250. The 30% assumption is not an official rate assigned to a province or a recommendation. Change it to see how the arithmetic changes.

What the calculator does not determine

Whether a transaction is on capital account or business income.
Whether the adjusted cost base and expenses you entered are correct.
Principal-residence exemptions, capital-gains deductions, donations, reserves, deemed dispositions, rollovers or other special treatment.
Capital-loss eligibility or offsets, depreciation recapture, alternative minimum tax, benefit changes, provincial surtaxes or the effect of crossing brackets.
Your filing obligations or the final amount assessed by the CRA.

A negative arithmetic result is shown as a loss before special rules. It is not automatically a deductible loss or a tax refund.

Methodology

Proceeds minus adjusted cost base minus eligible selling expenses. Positive ordinary non-exempt gain × one-half inclusion × the user’s combined marginal-rate assumption. Does not model brackets, exemptions, loss offsets or a complete tax return.

Capital Gains When Someone Dies in Canada: 2026 Estate Tax Guide What an executor needs to know about capital gains tax on death in 2026: deemed disposition, the inclusion rate that applies, principal residence exemption, adjusted cost base for heirs, and the split between final return and estate (T3) return.
