How to Calculate Capital Gains in Ontario

Calculating capital gains in Ontario involves determining the profit from selling an asset and applying Ontario's tax rules. This guide explains the process step-by-step, including how to calculate your gain, apply deductions, and determine your tax liability.

What Are Capital Gains?

Capital gains are the profits realized from selling an asset for more than its original purchase price. In Ontario, capital gains are taxable events that can affect your overall tax liability. The Ontario government treats capital gains differently from ordinary income, with specific rules for calculating and reporting them.

Key Points

Capital gains are calculated as the difference between the sale price and the adjusted cost base of the asset.
Ontario applies its own tax rates to capital gains, which may differ from federal rates.
Deductions and exemptions can reduce the taxable amount of capital gains.

How Ontario Calculates Capital Gains

Ontario calculates capital gains using the following formula:

Capital Gain Formula

Capital Gain = Sale Price - Adjusted Cost Base

The Adjusted Cost Base is the original purchase price plus any capital expenditures related to the asset.

Once the capital gain is calculated, Ontario applies its progressive tax rates to the amount. The tax rates for capital gains in Ontario are as follows:

Taxable Income	Capital Gains Tax Rate
$0 - $44,792	5.05%
$44,792 - $89,585	9.15%
$89,585 - $150,000	11.16%
$150,000 - $220,000	12.16%
Over $220,000	13.16%

These rates are subject to change and should be verified with the latest Ontario tax tables.

Step-by-Step Calculation

Determine the Sale Price: This is the amount you received from selling the asset.
Calculate the Adjusted Cost Base: Add the original purchase price to any capital expenditures (e.g., repairs, improvements).
Compute the Capital Gain: Subtract the Adjusted Cost Base from the Sale Price.
Apply Ontario Tax Rates: Use the Ontario capital gains tax table to determine the tax owed.
Account for Deductions: Subtract any eligible deductions (e.g., capital losses, principal residence exemption).

Example Calculation

If you sold a property for $500,000 and the Adjusted Cost Base was $300,000, your capital gain would be $200,000. Using the Ontario tax rates, you would owe approximately $18,316 in capital gains tax.

Tax Rates in Ontario

Ontario's capital gains tax rates are progressive, meaning higher income brackets pay higher rates. The rates are applied to the entire capital gain, not just the portion that exceeds a certain threshold.

For example, if your capital gain is $200,000 and your taxable income is $100,000, you would pay:

$44,792 at 5.05% = $2,263.89
$44,793 - $89,585 at 9.15% = $4,186.94
$89,586 - $150,000 at 11.16% = $6,664.16
$150,000 - $200,000 at 12.16% = $5,080.00

Total capital gains tax = $2,263.89 + $4,186.94 + $6,664.16 + $5,080.00 = $18,194.99

Note

These calculations are simplified. Always consult a tax professional for personalized advice.

Common Mistakes to Avoid

Underestimating the Adjusted Cost Base: Forgetting to include all capital expenditures can lead to underreporting gains.
Ignoring Tax Rates: Applying federal tax rates instead of Ontario's rates can result in incorrect tax calculations.
Failing to Report Capital Gains: Not reporting capital gains on time can lead to penalties and interest charges.
Overlooking Deductions: Missing out on eligible deductions can increase your tax liability unnecessarily.
