Capital Gain Tax Ontario Calculator

Use our Capital Gain Tax Ontario Calculator to determine how much capital gains tax you owe when selling an asset in Ontario. This calculator helps you understand the tax implications of your capital gains based on your sale price, purchase price, and holding period.

How to Calculate Capital Gain Tax in Ontario

Capital gains tax in Ontario is calculated based on the difference between the sale price of an asset and its original purchase price, minus any capital costs. The tax rate depends on how long you held the asset.

Capital Gain Formula

Capital Gain = Sale Price - Purchase Price - Capital Costs

Once you've calculated your capital gain, you'll need to determine the applicable tax rate based on your holding period:

Short-term capital gains (held for 1 year or less)
Long-term capital gains (held for more than 1 year)

Important Note

In Ontario, capital gains tax is calculated on the federal level, not at the provincial level. This means the same capital gains tax rates apply in Ontario as in the rest of Canada.

Ontario Capital Gains Tax Rates

The capital gains tax rates in Ontario are the same as the federal rates because capital gains tax is a federal tax. Here are the current rates:

Holding Period	Tax Rate
Short-term (≤1 year)	50% of the capital gain
Long-term (>1 year)	50% of the capital gain (if the gain is over $1,000)

There is no capital gains tax on long-term capital gains that are $1,000 or less. This means if you have a long-term capital gain of $900, you won't owe any capital gains tax on that amount.

Examples of Capital Gain Tax Calculations

Let's look at two examples to illustrate how capital gains tax is calculated in Ontario.

Example 1: Short-term Capital Gain

You bought a stock for $10,000 and sold it for $15,000 after holding it for 6 months. There were no capital costs.

Calculation

Capital Gain = $15,000 - $10,000 - $0 = $5,000

Tax Rate = 50% (short-term)

Capital Gains Tax = $5,000 × 50% = $2,500

Example 2: Long-term Capital Gain

You bought a house for $300,000 and sold it for $400,000 after holding it for 3 years. There were capital costs of $5,000.

Calculation

Capital Gain = $400,000 - $300,000 - $5,000 = $95,000

Tax Rate = 50% (long-term, since gain > $1,000)

Capital Gains Tax = $95,000 × 50% = $47,500
