When you sell a capital property - stocks, mutual funds, real estate, or cryptocurrency - for more than you paid, you realize a capital gain. In Canada, only a portion of the gain is included in your taxable income; the remainder is tax-free. For individuals in 2026, the inclusion rate remains at 50%. The included portion is then taxed at your regular marginal rate alongside all other income. This calculator takes your adjusted cost base (ACB), proceeds of disposition, and province and computes your estimated tax payable on the gain. It also models capital loss harvesting - if you have unrealized losses elsewhere, offsetting them against gains can reduce your bill. Principal residence sales are generally exempt from capital gains tax; this tool focuses on investment assets.
