How capital gains tax works in Canada

In Canada, you generally pay tax on 50% of your capital gain (for most individual scenarios). That taxable half is added to your income and taxed at your marginal tax rate. So if you sell stocks, a rental property, or other capital assets at a profit, only part of that gain becomes taxable income.

Basic formula

• Capital gain = Sale price − Adjusted cost base (ACB) − Selling costs
• Net capital gain = Capital gain − Capital losses carried forward
• Taxable capital gain = Net capital gain × Inclusion rate

Then your taxable capital gain is added to your other income for the year, and your tax bill increases based on your federal + provincial/territorial marginal rates.

What to include in adjusted cost base (ACB)

Your ACB is often more than just the original purchase price. Depending on the asset, it may include:

• Purchase price
• Acquisition costs (legal fees, commissions)
• Capital improvements (for real estate)
• Reinvested distributions (for some investment funds)

Keeping good records matters. A higher valid ACB can reduce your capital gain and your tax.

Common expenses that reduce gains

You can usually deduct direct selling costs from proceeds when calculating the gain. Examples:

• Realtor commissions
• Legal fees
• Outlays directly tied to disposition

Principal residence exemption

For many Canadians, the sale of a qualifying principal residence is exempt from capital gains tax. This calculator includes a quick principal residence option for rough planning, but real eligibility can be nuanced (for example, years designated, change of use, partial rental use, trusts, and ownership structure).

Why province matters

Canada’s tax system combines federal and provincial/territorial rates. Two people with the same capital gain can pay different tax depending on where they live and their income level. That’s why this calculator asks for your location and other taxable income.

Example scenario

Suppose you sell an investment property for CAD 700,000, with an ACB of CAD 500,000 and selling costs of CAD 30,000:

• Capital gain = 700,000 − 500,000 − 30,000 = 170,000
• No carried losses, 50% inclusion rate
• Taxable capital gain = 85,000

That CAD 85,000 is added to your other taxable income, and the tax impact depends on your total marginal bracket progression.

Tips to reduce capital gains tax legally

• Track ACB carefully and retain supporting documents
• Use capital losses strategically (current year or carryforward)
• Spread dispositions across tax years when possible
• Consider registered accounts (TFSA/RRSP rules differ by account type)
• Get personalized advice before large transactions

Frequently asked questions

Do I pay capital gains tax on 100% of my gain?

Usually no. For most individual cases, only the taxable portion (often 50%) is included in income.

Can capital losses reduce salary income directly?

Generally, net capital losses offset taxable capital gains, not regular employment income, with specific carryback/carryforward rules.

Is this calculator CRA-official?

No. It is an educational estimator to help with planning. Always verify with CRA guidance and a tax professional for filing decisions.
