When you sell an investment — a stock, rental property, or business — for more than you paid, you've earned a capital gain. The CRA taxes a portion of that gain as income.

For a full list of CRA payment deadlines, use the free AINative Tax Deadline Calculator — it includes the April 30 capital gains payment date alongside all your other CRA dates.

Understanding how capital gains tax works in Canada is essential for investors, business owners, and anyone selling property. This guide explains the rules, the math, and the key exemptions that can reduce what you owe.

What Is Capital Gains Tax in Canada?

Capital gains tax in Canada works through an inclusion rate — only a percentage of your capital gain is added to your taxable income. The rest is tax-free.

For individuals in 2026:

  • 50% inclusion rate on the first $250,000 of capital gains per year
  • 66.67% (two-thirds) inclusion rate on capital gains above $250,000 per year
  • The included amount is taxed at your marginal income tax rate

For corporations and trusts:

  • 66.67% (two-thirds) of all capital gains are included in taxable income (no $250,000 threshold)

Note: The increased inclusion rate above $250,000 was proposed in the 2024 federal budget, deferred to January 1, 2026, and applies to dispositions on or after that date. As of May 2026, the required legislation has received Royal Assent but consult a tax professional to confirm the current status of this measure.

How to Calculate Your Capital Gain

Capital Gain = Proceeds of Disposition − Adjusted Cost Base (ACB) − Selling Expenses

Example:

  • You sell shares for $50,000
  • You originally paid $30,000 (your ACB)
  • You paid $500 in brokerage fees (selling expenses)
  • Capital gain = $50,000 − $30,000 − $500 = $19,500

At the 50% inclusion rate:

  • Taxable capital gain = $9,750

This $9,750 is added to your income for the year and taxed at your marginal rate.

Canadian Capital Gains Tax Calculator

While we don't display specific tax rates (they vary by province and income bracket), the formula is consistent:

1. Calculate your capital gain: Proceeds − ACB − Selling Expenses = Capital Gain

2. Apply the inclusion rate (individuals, 2026):

  • First $250,000 of gains: Capital Gain × 0.50 = Taxable Capital Gain
  • Gains above $250,000: Excess × 0.6667 = Additional Taxable Capital Gain

3. Apply your marginal rate: Taxable Capital Gain × Your Marginal Rate = Tax Owing

Your combined federal and provincial marginal rate on the included gain can range from approximately 22% to 54% depending on your province and income level. Use the CRA's income tax calculator for a personalized estimate.

The Principal Residence Exemption

If you sell your primary home, you may qualify for the principal residence exemption — one of the most valuable tax breaks in Canada. If the property was your principal residence for every year you owned it, the entire capital gain is exempt from tax.

Even if you didn't live there every year (for example, you rented it out for a period), you may still qualify for a partial exemption using the CRA's formula.

You must report the sale on your T1 return in the year it occurs, even if the gain is fully exempt. File Schedule 3 and designate the property as your principal residence.

Lifetime Capital Gains Exemption (LCGE)

If you sell qualifying small business corporation shares or qualifying farm and fishing property, you may be eligible for the Lifetime Capital Gains Exemption — sheltering up to $1,250,000 of capital gains from tax in 2026.

This is a major planning tool for small business owners. To qualify, the corporation must meet CRA's definitions of a Canadian-Controlled Private Corporation (CCPC) and the shares must pass various tests.

Consult a tax professional if you're planning to sell a business — the LCGE can save you hundreds of thousands in taxes if structured correctly.

Capital Losses: How They Work

If you sell an investment for less than you paid, you have a capital loss. Capital losses can offset capital gains in the same year, reducing your tax. If losses exceed gains, the net capital loss can be:

  • Applied to capital gains in the 3 prior tax years
  • Carried forward indefinitely to offset future capital gains

Capital losses cannot offset other types of income (employment income, business income, etc.) — only capital gains.

When Do You Pay Capital Gains Tax?

Capital gains are reported on your T1 personal income tax return for the year in which the disposition (sale) occurred. The balance owing is due:

  • April 30 for most Canadians
  • June 15 if you or your spouse are self-employed (but payment is still due April 30)

Capital Gains Tax Rates by Province

The effective tax rate on capital gains varies significantly by province. For the first $250,000 of gains (50% inclusion), the included amount is taxed at your combined federal + provincial marginal rate. Here are the approximate top combined marginal rates for 2026:

ProvinceTop Combined Marginal RateEffective Rate on Capital Gains (50% inclusion)
British Columbia~53.50%~26.75%
Alberta~48.00%~24.00%
Saskatchewan~47.50%~23.75%
Manitoba~50.40%~25.20%
Ontario~53.53%~26.76%
Quebec~53.31%~26.65%
New Brunswick~52.50%~26.25%
Nova Scotia~54.00%~27.00%
PEI~51.75%~25.88%
Newfoundland & Labrador~54.80%~27.40%

For capital gains above $250,000, the 66.67% inclusion rate applies, making the effective top rates roughly one-third higher (e.g., ~35.67% in BC instead of ~26.75%).

Important: These rates are approximate and reflect top marginal brackets including provincial surtaxes where applicable. Rates may change with provincial budgets. Verify current rates at TaxTips.ca or consult your accountant. Most Canadians pay a lower effective rate.

How to Calculate Capital Gains on Property in Canada

Real estate capital gains follow the same formula as other assets, but there are additional considerations:

  1. Adjusted Cost Base (ACB) includes the purchase price plus qualifying capital improvements (renovations that increase value, not routine maintenance), legal fees, and land transfer tax
  2. Selling expenses include real estate commission, legal fees, and staging costs
  3. Principal residence exemption — if the property was your primary home for every year you owned it, the entire gain may be exempt (see above)
  4. Partial exemption — if you lived in the property for some years and rented it for others, use the CRA formula: (1 + years designated) / years owned

Example: Selling a rental property in BC

  • Purchase price (2018): $500,000
  • Capital improvements: $40,000
  • Selling price (2026): $750,000
  • Commission + legal: $30,000
  • ACB = $500,000 + $40,000 = $540,000
  • Capital gain = $750,000 − $540,000 − $30,000 = $180,000
  • Taxable capital gain (50% inclusion, since under $250K) = $90,000
  • At BC's top marginal rate (~53.50%): up to ~$48,150 in tax on that $90,000

Note: Your actual tax depends on your total income and marginal bracket — the amount above assumes the full gain is taxed at the top rate, which is unlikely for most taxpayers.

Capital Gains on Cryptocurrency in Canada

The CRA treats cryptocurrency as a commodity (a form of property), not currency. Disposing of crypto — selling, trading for another crypto, or using it to buy goods — triggers a capital gain or loss.

Key rules for crypto:

  • Each disposition (including crypto-to-crypto trades) is a taxable event
  • Your ACB must be tracked across all wallets and exchanges using the weighted average cost method
  • Mining: The CRA's position is that mining operations that are organized, continuous, or profit-oriented are treated as business income (100% taxable). Casual or hobbyist mining may be treated differently — the determination depends on the specific facts of your situation
  • Staking: Staking rewards and yield farming income are generally treated as income (similar to interest), taxable at fair market value when received — not as capital gains
  • Airdrops and forks may be taxable at the time received, depending on the circumstances

Important: The CRA has been increasing its enforcement of crypto reporting. If the total cost of your foreign-held crypto exceeds $100,000 at any point during the year, you may need to file Form T1135. Consult a tax professional for guidance specific to your crypto activity.

If crypto is a significant part of your portfolio, consider using AI-powered tools that can automatically track ACB across exchanges.

Frequently Asked Questions

How much capital gains is tax-free in Canada? There is no blanket tax-free amount for capital gains. However, the principal residence exemption can make gains on your primary home 100% tax-free. The Lifetime Capital Gains Exemption shelters up to $1,250,000 on qualifying small business shares and farm/fishing property. For individuals, the first $250,000 of annual capital gains is included at 50%, with gains above that included at 66.67%.

Do I have to pay capital gains tax if I reinvest the proceeds? Yes. Unlike some U.S. rules (such as 1031 exchanges), Canada does not have a general "rollover" for reinvested capital gains. You owe tax in the year of disposition regardless of what you do with the proceeds. Exceptions exist for specific situations like transfers to a spouse or qualifying corporate reorganizations.

How do I report capital gains on my tax return? Report capital gains on Schedule 3 of your T1 return. You'll need the proceeds of disposition, ACB, and any outlays/expenses for each transaction. The net taxable capital gain flows to line 12700 of your return.

Can capital losses offset other income? No. Capital losses can only offset capital gains — not employment, business, or other income. Unused net capital losses can be carried back 3 years or carried forward indefinitely.
