How Is Capital Gains Calculated in Ontario

Capital gains in Ontario are calculated based on the difference between the sale price of an asset and its original cost, adjusted for certain deductions and exemptions. The tax rate applied depends on your income level and whether you're a resident or non-resident of Ontario.

How Capital Gains Are Calculated

The basic formula for calculating capital gains is:

Capital Gain = Sale Price - (Original Cost + Adjustments)

Where "Adjustments" include:

Capital cost allowance (CCA) deductions for depreciable assets
Other allowable deductions such as legal fees and brokerage commissions
Any capital losses carried forward from previous years

If the capital gain is positive, it's added to your taxable income for that year. If it's negative, it can offset other capital gains or be carried forward to future years.

Tax Rates in Ontario

Ontario uses a progressive tax system for capital gains. The tax rate depends on your total income, including the capital gain. Here are the current rates (as of 2023):

Income Bracket	Capital Gains Tax Rate

Over $98,040	53.79%

Non-residents of Ontario are taxed at a flat rate of 50% on their worldwide income, including capital gains.

Capital Gains Exemptions

Ontario offers several exemptions that can reduce or eliminate capital gains tax:

Principal Residence Exemption: Up to $400,000 for the sale of your primary home (indexed annually)
Small Business Capital Gains Exemption: Up to $500,000 for small businesses (indexed annually)
Rental Property Exemption: Up to $250,000 for the sale of rental properties (indexed annually)
Farmland Exemption: Up to $1,000,000 for the sale of farmland (indexed annually)

These exemptions are applied before calculating the taxable capital gain.

Example Calculation

Let's look at an example where you sell a property for $500,000 that you originally purchased for $300,000. You've claimed $50,000 in capital cost allowance deductions.

Capital Gain = $500,000 - ($300,000 + $50,000) = $150,000

Assuming your total income is $80,000 (below the first tax bracket), the capital gains tax would be:

Capital Gains Tax = $150,000 × 50.92% = $76,380

If you qualify for the principal residence exemption, the taxable gain would be reduced by $400,000 (or $150,000 if the exemption is less than the gain).
