What capital gains inclusion rate does this calculator use?

It uses the currently enacted Canadian inclusion rate of one-half, meaning 50% of a capital gain is included in taxable income. The federal government confirmed in Budget 2025 that it would not proceed with the proposed increase.

What belongs in adjusted cost base?

Adjusted cost base can include purchase cost and qualifying capital additions. The treatment of legal fees, commissions, improvements, depreciation, and prior elections depends on the asset and facts.

Does this calculate my exact tax bill?

No. It estimates tax by multiplying the taxable half of the gain by the marginal rate you enter. An actual return applies tax brackets, deductions, losses, exemptions, and provincial rules.

Is a principal residence taxable?

A qualifying principal residence may be sheltered by the principal residence exemption, but reporting and eligibility rules still apply. Get tax advice for mixed-use, rental, or partially designated property.

Canada currently includes 50% of a capital gain in taxable income. The proposed increase to two-thirds was not implemented. This tool uses the enacted one-half rate and lets you enter a marginal tax rate for a planning estimate.

How the estimate works

Net proceeds subtract selling costs from the sale price. Adjusted cost base starts with acquisition cost and may include qualifying capital additions.

Worked example

A simplified property example using a 43.41% marginal rate.

Find adjusted cost base

Add the entered purchase cost and capital improvements.

$400,000 + $30,000 = $430,000

Find net proceeds

Subtract selling costs from sale price.

$750,000 − $35,000 = $715,000

Find the capital gain

This example assumes no other adjustments.

$715,000 − $430,000 = $285,000

Apply the 50% inclusion rate

Half the gain enters taxable income.

$285,000 × 50% = $142,500 taxable

Estimate tax

The exact return calculation may differ materially.

$142,500 × 43.41% = $61,859
